Coded light source activation

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to communication engineering and can be used in optical communication systems. A coded light source in an illumination system is activated using a remote control device. If light source identification is successful, said light source is sent a control message to at least partially turn off its light. The light input of the identified light source is therefore turned off, thereby reducing the probability of conflict of coded light from an already identified light source with identifiers contained in the coded light emitted by other light sources. When there is no more detectable coded light, the sensitivity of the remote control device can be raised until the coded light is detectable again. Additional light sources can then be identified and activated.

EFFECT: improved noise-immunity.

The technical field TO WHICH the INVENTION RELATES

The present invention relates to a light source. Specifically it relates to methods and devices for commissioning a light source in an illumination system, comprising a plurality of light sources capable of emitting coded light.

The prior art TO WHICH the INVENTION PERTAINS

The use of optical communication in free space, i.e., visible light (VL) and infrared communication (IR) range, to select and control the light sources have been proposed previously, and will be called coded light (CL). To transfer CL as light sources in lighting fixtures, mainly discusses light-emitting diodes (LEDs), which allow for more acceptable bandwidth modulation. This, in turn, can lead to a quick response to the received control systems. Although generally treated Seeds, but other light sources (incandescent, halogen, fluorescent and discharge lamps high intensity discharge (HID)) also provide the ability to embed identifiers in the light, but mostly at lower speeds.

Coded light can be used to embed unique identifiers, or codes, in different light output of East�shnikov light. Using these identifiers, the light emitted from the special light sources can be identified in the presence of deposits in lighting from other light sources. This identification of individual contributions to the coverage provides for such uses as a light source, indication and control, commissioning and interactive setting zone. These applications find use, for example, in homes, offices, shops, cars and hospitals. These identifiers light sources provide a simple and intuitive control over the operation of the lighting system, which could be very difficult.

One particular category of applications, which provides an opportunity to CL is room automatic commissioning. In this application the control device receives the modulated light from the various lamps in the room. After extracting the identification code from the modulated light control device creates a (wireless) communication line identified with lamps, giving it the ability to manage them. This is the establishment of binding and control relations is the fact that hereinafter collectively referred to as commissioning.

The sensitivity of the control device creates a practical problem, especially for lamps, �located remotely from the location of the control device. These lamps provide only a small contribution to the light passed by the control device, hampering the successful extraction of identifiers. In addition, if the individual lamps emit their identification in the random access mode (for example, using a trimmed ALOHA Protocol), there can be many conflicts before an identification code is retrieved correctly.

WO 03/007665 A1 relates to wireless control of lighting equipment and lamps, and more particularly to a system and method for configuring networks to control lighting and lamps, using information about the location of lighting fixtures and lamps. The aim WO 03/007665 A1 is the provision of a system and method for associating groups of devices, such as lamps, where there is no unsolicited communications of a particular lamp or lamps. Therefore, provided the communication method of one or more lamps from the neighborhood group to the management group run together.

WO 2008/065607 A2 provides an illumination system for communication with the remote control device that contains a light-emitting element adapted to emit modulated light to the remote control device and for detecting control signals from a remote control device. This can before�to put the link between the remote control device and lighting system without the need of an additional sensor or an additional transmitter.

Summary of the INVENTION

The purpose of the present invention is to overcome this problem and to provide funds for improved commissioning of light sources. The specific objective is to provide funds for commissioning of light sources, in which coded light passed by the light detector, contains the identifiers associated with a variety of light intensities.

Typically, the above goals are achieved by a remote control device according to the appended independent claim.

According to the first aspect of the invention, this and other objectives are achieved by a remote control device for operation of the light source in the system of the coded light comprising a plurality of light sources capable of emitting coded light, comprising: a light detector; a processing unit coupled to the light detector and arranged to determine the ID of the light source based on light, another light detector, thereby identifying the light source; and a transmitter, configured to send a command to the identified light source at least partly switch off its light emission; and wherein the processing unit is arranged to prescriptions transmitter transmit� command in response to identification of the source of light, thereby triggering the operation of the light source.

Preferably the invention a method for automatically commissioning process allows commissioning to be completed in a limited period of time, avoiding the many conflicts of the signals present in the prior art. The method allows for the commissioning of light sources of the luminaires close to the remote control device (that is, those who give the strongest signal) first, before moving on to another. In other words, when the light emission of the identified light source at least partially disabled, his light contribution is reduced, thereby reducing the risk of conflict with other identifiers of the light sources. On average, the light sources are located close to, will be identified first.

The remote control device may further comprise an amplifier with adjustable gain is connected to the light detector and arranged to decrease the sensitivity of the light detector until such time as adopted in the light of not more than one identifier will detect. With a small gain remote light sources will produce deposits signals that are hidden in the quantization noise and therefore are not detector.�trolled. Thus are detektirovanie only sources of light near.

The remote control device may further comprise an amplifier with adjustable gain is connected to the light detector and configured to increase the sensitivity of the light detector until such time as at least one identifier in a received light will detect. Preferably, the sensitivity may be improved if the identifiers of the light sources are not datetimetype. Thus, the detection capability of the light source may be increased.

Even if you have already identified the muted light sources emitting light, it still can serve as a hindrance to the light sources associated with weak intensities. Therefore, the remote control device may further comprise a memory connected to the processing unit and configured to store identifiers of a plurality of light sources; wherein the processing unit is arranged to, during the determination of the identifier of the light source, compare the identifier of the light source with the stored identifiers previously identified light sources; and wherein the memory is configured to add the identifier of the identified source of Sveta memory in response to that the identified light source was identified. Preferably, the remote control device may thus reduce the risk of identification of a single light source twice.

The remote control device may be performed sequentially increasing the sensitivity of the light detector, thereby allowing the processing unit to consistently identify the light sources one by one; and a memory configured to save the IDs consistently identified light sources one by one in the memory, in response to what has consistently identified the light source was identified. Therefore, such a remote control device may provide the possibility of effective and consistent identification of light sources one by one in the system of the coded lighting.

The remote control device may be configured to transmit the identified light source additional commands related to managing the identified property of light of the light source, in which the impact of management depends on at least one from the group: (i) intensity level, and (ii) another angle of entry of light associated with Ident�Spain and Portugal light source. The transmitter can be configured to transmit additional commands if the intensity level is higher than the specified threshold, and/or the angle of entry is within a predetermined interval. Preferably, the remote control device may thus be able to control the light sources exclusively within a predetermined range of distances from the remote controller.

The remote control device may be limited to control the subset of light sources in a variety of light sources in the coded system of illumination; and wherein the transmitter is arranged to transmit additional commands, solely in the case that the identified light source is contained in the subset. Preferably, the remote control device may, thus, be able to operate exclusively given number of light sources. These light sources may correspond to the first detektirovanie light sources. These first detected light sources may correspond to the light sources located within a predetermined range of distances from the remote controller.

The processing unit may include a communication interface coupled to the processing unit, whereby the device �stantsionnogo management is able to share information, related to identify light sources and/or from at least a second device remote control. Preferably, this allows the remote control device to exchange information at least with a second device remote control. Using this information, the commissioning can be improved, for example, increase the reliability of the identification.

According to the second aspect, these objectives are achieved by a method for commissioning a light source in a coded system of lighting, comprising stages of: emitting the coded light from the light source; detecting light with remote control device; determining by the remote control device identifier of the light source on the basis of another light, thereby identifying the light source; and transmitting the remote control command to the identified light source at least partially disable the emission of light, wherein the command is transmitted in response to the identification of the light source, thereby giving the effect of a light source.

Typically, the features and advantages of the first aspect are also applicable to the second aspect. It should be noted that the invention relates to all possible combinations of the signs listed � the claims.

DETAILED DESCRIPTION

The following implementation options are provided as examples so that this disclosure will be exhaustive and complete, and will fully convey the scope of the invention to specialists in this field of technology. The same numbers indicate the same elements throughout.

Fig.1 illustrates a lighting system 100, comprising at least one light source, schematically indicated by the reference position 102. The light source 102 may be part of a lighting control system, thus, the lighting system 100 may be denoted as a system of coded light. It should be noted that the term "light source" means a device used to ensure�of moving light in the room, to highlight items in the room. Examples of such devices provide light contain lighting devices and lamps. The room, in this context, is a typical residential room or office space, a gymnasium, a car, a room in a public place or part of the external environment, such as part of the street. Each source light 102 is capable of emitting light, as schematically illustrated by arrow 106.

Due to the large number of source light 102, the distance between the source light 102 and a wide range of illumination levels that can be supported by each source light 102, the complexity of controlling such a lighting system 100 is pretty high. According to the state of the prior art, only a small number of source light 102 can be implemented in the lighting system 100 on the basis of the encoded illumination within a limited amount of time. This and other problems can be overcome by methods, devices, and system approaches, as discussed below, which improve the introduction of the source light 102 in the lighting system 100 through improved detection IDs and control the source light 102.

The emitted modulated light contains a part that is associated with a coded light containing �identificator light source. Method of operation of the light source will be disclosed below. The emitted light may also contain nemoderiruemye part associated with the contribution to the lighting. Each source light 102 may be associated with a number of lighting settings, in particular relating to the contribution to the illumination light source, such as color, color temperature, dimming level and the intensity of the light emitted. In basic words, the contribution to the illumination light source can be defined as srednevekovoi light output emitted by the source 102 of the light. The lighting system 100 further comprises one or more devices 104A, 104b remote control for the detection, receiving and processing light, such as coded light containing the ID of the source light emitted by the source 102 of the light and the light emitted by light sources outside the system 100 of light (not shown). Thus, the encoded signals of the light can be emitted not only by lamps or light sources, as well as other devices, such as sensors, switches and other climate appliances such as air conditioners, controllers, shutters, ventilation units, thermostats and heating blocks (e.g., using LEDs that emit white, infrared radiation or other color). In this case, these devices are also m�may be found and associated with the lighting system 100.

With reference to Fig.1, the user may be required to control the source light 102 in the lighting system 100, using a device 104a, 104b remote control. Therefore, the first light source and possibly other connected device must be entered in the action. To this end, the sources 102 emit light of a unique identifier by means of visible light 106. The device 104a, 104b remote control has a (directional optical) light sensor, which can distinguish between light contributions of different light sources and choose suitable source of light 102. This source 102 of the light can then be directed through the communication line, for example the wireless link 108, for example, based on ZigBee.

The user may also need control of the source light 102 in the lighting system 100 in order to create light in a certain position and/or with a desired intensity and/or color of light. To this end, the sources 102 emit light of a unique identifier by means of visible light 106. The device 104a, 104b remote control has svetopriemnik, and it allows to distinguish and to evaluate the size of the light contributions of the various sources of light 102 at that location. The device 104a, 104b controller may then estimate the required contributions of the identified sources of light 102 and to inform Nova� settings of the light sources 102 of the light as indicated by the arrow 108 in Fig.1. In addition, as indicated by the reference position 110, the information is processed by a separate device 104A remote control, can be communicated to another individual device 104b remote control.

The scenario above practical issues include the sensitivity of the device 104a, 104b remote control in order to be able to detect all sources 102 light in the room. Specifically, for the lamps that are on, only a small contribution of the emitted light reaches the detector device 104a, 104b remote control. In addition, the individual lamps emit their identifiers in the form of a trimmed ALOHA. According to the nature of random access protocols like ALOHA, each source light 102 sends its ID in a particular time each time interval. This time is arbitrary from time interval to time interval. This means that conflicts can occur before identification will be accepted correctly. Due to the effects of capture reliably received packets can be learned from the conflict, but will be more difficult, if not impossible, to perform identification of light sources farther away.

In rooms�ohms automatic commissioning according to the present invention, the device 104a, 104b remote control receives the modulated light from the various lamps in the room, detects identification lamps from the modulated light emitted by the source 102 of the light fixtures, and creates a (wireless) communication line with these lamps, it allows the control device to control them.

Fig.2 schematically illustrates a functional block diagram of the source 200 of the light, such as the source light 102 of Fig.1, disclosed above. The source 200 of the light can thus be configured to emit illumination light, and also, as coded light and the coded light contains the source identifier of the light source 200 of the light. The source 200 of the light may be provided with identifiers in the production process. The identifier may correspond to the MAC address of the source of light. The MAC address may be a length of the order of 32 to 64 bits. Source 200 contains a light emitter 202 for emitting the coded light. The emitter 202 may contain one or more Seeds, but it may also contain one or more FL or HID sources, etc. When used to identify an additional light emitter, such as an IR LED, the emitter will be placed in proximity to the primary emitter. The main emitter is associated with lighting function isto�nick light (i.e. the light emission of the light) and can be any emitter, and the secondary emitter is associated with the identifier of the light source (i.e., for emitting the coded light). Preferably, the secondary emitter was led. Thus, in some embodiments, the emitter 202 includes a primary light emitter for emitting light and a secondary light emitter for transmitting coded light. In some embodiments, a single light emitter is a main and a secondary emitter. Source 200 further comprises a light receiver 208 for receiving information relating to the configuration of the source 200 of the light. Setting may refer to color, color temperature, dimming level and intensity of the light emitted by the source 200 of the light. The source 200 of the light may further contain other components, such as block 204 processing, such as a Central processing unit (CPU) and a memory 206. For example, through the use of block 204 of processing, the source 200 of the light can change the settings of the light emitted. Information related to identifiers, such as identifiers and parameters code may be stored in memory 206.

Lamps (not shown) may contain at least one source 200 lights, with each light source can be assigned individual � unique identifiers of the light source. Preferably, this light source was the light source based on LED.

Functional block diagram of a device 300 remote control, such as the device 104a, 104b remote control of Fig.1, shown in Fig.3. The device 300 remote control contains a processing unit, schematically illustrated by the reference position 302, made with the possibility of introduction of the source 102, 200 light based on the light detected by the detector 304 of the light receiver 300. In order to achieve this commissioning, the device 300 remote control is made with the possibility of implementation of some functionality. These functionalities will be described below with reference to the block diagram of the sequence of operations of the method of Fig.4. The device 300 remote control further comprises a memory 306, a transmitter 308, amplifier 310 with adjustable gain and an interface 312 connected. The memory 306 may store instructions relating to the functionality of the entry into force of the springs 102, 200 light. The memory 306 may optionally be stored identifiers of a plurality of light sources. The transmitter 308 may be used to inform commissioning of the source light 102 in the lighting system 100. The amplifier 310 with a variable gain amplified�I can be used to increase or decrease the sensitivity of the detector 304 light. The interface 312 may be used to allow the device 300 remote control to communicate with other devices remote control or with the main controller of the lighting system 100. The device 300 remote control can be a device mounted on the desktop, with Omni-directional detector 304 light. This device 300 remote control can have either a wired or wireless communication line (e.g., ZigBee) for lamps.

Method of commissioning sources 102, 200 lights in the system 100 of the encoded illumination will be described with reference to the block diagram of the sequence of operations of the method of Fig.4. Lamps or sources 102, 200 light contained in the lamps that are entered in the input mode in the action by a General command to emit coded light. Alternatively, the lamps can emit their identification all the time, when they emit light until they are enacted. Thus, in step 402, the encoded light is emitted from at least one source 102, 200 lights in the system 100 of the coded lighting.

Light containing the encoded light emitted from at least one source 102, 200 light detector detects light 304 of the device 104a, 104b, 300 remote control, step 404. It should be noted that when�'yaty light may also include a contribution to the illumination from the light sources, not included in the system 100 of the coded lighting.

The device 104a, 104b, 300 remote control determines the identity of one of the source light 102 on the basis of another light, stage 406. The light source 102, 200 thereby identified.

If the system 100 coded light contains a large number of sources 102 light, it may be difficult to correctly identify each of the sources 102 of the light. In particular, the potential for conflict, according to the ALOHA Protocol, increases with the number of light sources. The amplifier 310 with adjustable gain device 104a, 104b, 300 remote control can therefore be used so that the source light 102 can be correctly identified, one by one. In particular, if the sensitivity of the detector 304 of light is too high, it may be difficult to distinguish one identifier from another. Consequently, the amplifier 310 with adjustable gain can be configured to reduce, in step 410, the sensitivity of the detector 304 light until such time as adopted in the light of not more than one identifier will detect. Not more than one identifier may correspond to the source 102 of the light emitting coded light with higher intensity than other light sources with�system 100 coded lighting. Not more than one identifier may also correspond to the source light 102 having the smallest distance to the device 104a, 104b remote control compared to other light sources in the system 100 of the coded lighting. Similarly, if the sensitivity of the detector 304 light is too low, none of the IDs cannot be detected. Consequently, the amplifier 310 with adjustable gain can be made with the possibility to increase the sensitivity of the light detector until such time as at least one detect the identifier will be adopted in the light.

The processing unit 302 may be configured to, when determining the identifier of the light source in step 412, compare the identifier of the source light 102, which is identified with the identifiers previously identified light sources. Such a comparison can be made possible, because the identity of the previously identified light sources can be stored in memory 306 of the device 300 remote control. Making such a comparison device 104a, 104b, 300 remote control can thereby avoid the danger (incorrectly) identify one source of light twice. When the source light 102 is already identified, the identifier identify�rovannogo source light 102 may be added in step 414, the memory 306, so that the identifier of the identified source light 102 could be used in future comparisons.

If the sensitivity of the detector 304 of the light was reduced until such time as adopted in the light of not more than one identifier will detect, and the number has been correctly identified (and stored in the memory 306), adopted the light no longer contains any redetection and unidentified identifiers. Therefore, the device 300 remote control may be configured to, in step 416, consistently improve the sensitivity of the detector 304 of light through the use of amplifier 310 with adjustable gain. In particular, the sensitivity of the detector 304 of light can be increased until such time as adopted in the light of another (unidentified) identifier will detect. Thereby, the processing unit 302 can consistently identify the source light 102 in the system 100 of the coded lighting one by one. Thus, the memory 306 can be configured to save the IDs consistently identified sources 102 light one by one in the memory 306 in response to what has consistently identified the source light 102 were identified. This can, in other words, �make the possibility of the iterative process for the commissioning of the source light 102 in the system 100 of the coded lighting as schematically marked reference position 418.

According to a variant implementation, the block 304, the processing may be configured to determine the identifier of the identified source light 102 through the first detected non-conflicting package identifiers of a plurality of sources of light 102 within a time period, for example, on the basis of pieces of teaching data in each packet identifiers. Subsequently, the data in the packet decode for the detection of the identifier.

The device 104a, 104b, 300 remote control then transmits the command to the identified source light 102, step 408. The command includes instructions for the identified source light 102 at least partially deactivate the emission of light. The command is passed directly in response to the fact that the source light 102 was identified device 104a, 104b, 300 remote control. Thus, the source 102 of the light injected into the action. Thus, the transfer command is part of the process of commissioning and as such does not depend on specific user input. The command passed to the identified source light 102 at least partially disable the light emission of the identified source light 102 may, therefore, not to be compared with the basic command initiated by the user�m, at least partial disabling of the light emission source 102 of the light in the lighting system 100.

According to variants of implementation of the present invention can be various ways for at least partial disabling of the light emission of the identified source light 102. For example, the command may contain information to disable only the modulated part of the light emitted by the identified source of light 102. The modulated part of the light emitted contains the ID of the source light 102. Thus the modulated part of the world has already identified the source light 102 can be a hindrance to the identifiers of the light sources, which have not yet been identified. By disabling only the modulated part of the light emitted source light 102 may be able to continue radiation (non-modulated) light. Thus, the source light 102 does not need the full power outage. This may be applicable to the light detector, which is mainly sensitive to the modulated signals. Alternatively, the device 104a, 104b, 300 remote control can be positioned so that it passes only the modulated part of the light emitted by the source 102 of the light. For example, the device 104a, 104b, 300 remote control can be mounted on the ceiling POM�absorption, thus, when a modulated light reflected by furniture, walls or floors of the premises. As a second example, the command contains information to dim the light emissions of the identified source light 102. According to the embodiment of the muted only the modulated part of the light emitted. Thereby the danger of the modulated parts that hinder the identifiers of the light sources that have yet to be identified, reduced. According to the embodiment of the all light emitting identified by the source 102 of the light is attenuated. Such an implementation option can provide the user visual feedback that the source light 102 sequentially identified. As a third example, the command contains information to disable the entire light emission of the identified source light 102. Such a complete cessation of work may be preferable if the identified source light 102 is located close to the device 104A, 104b, 300 remote control and thereby dominates the light contribution of the light received by the detector 304 light of the device 104a, 104b, 300 remote control.

The device 104a, 104b, 300 remote control may be configured to transmit additional commands to identify the source light 102, step 420. �the team can refer to the management of the properties of light, the identified source 102 of the light, such as color, color temperature, dimming level and the intensity of the light emitted by the identified source of light 102.

According to variants of implementation, the impact of management depends on the properties of the light emitted by the identified source 102 of the light as received by the detector 304 light. For example, the impact of management may be dependent on the intensity level another light associated with the identified source of light 102. In General, the exposure control may be proportional to the level of the intensity of the received light; a higher level of intensity can be associated with a higher control effect than the reduced level of intensity. The meaning of this reasoning is that it is likely that a high level of intensity is associated with the source 102 of the light located in the vicinity of the device 104a, 104b, 300 remote control. Consequently, the device 104a, 104b, 300 remote control must be able to provide high impact control source light 102 that are located relatively close to the device 104a, 104b, 300 remote control than the light sources are located relatively far from the device 104a, 104b, 300 remote control. In �astnosti, the transmitter 308 may be configured to transmit additional commands if the intensity level is higher than a given threshold. In other words, if all light sources emit light with essentially the same intensity level, the device 104a, 104b, 300 remote control can only work on the control of light sources arranged within a predetermined radius of the device 104a, 104b, 300 remote control, where the radius is set to the respective predetermined threshold intensity. As a second example, the impact of management may depend on another angle of entry of light associated with the identified light source 102.

In particular, the transmitter 308 may be configured to transmit additional commands if the entrance angle is within a predetermined interval. The specified interval may, for example, be associated with the angle of entry corresponding to the source 102 of the light front, right above or right below the device 104a, 104b, 300 remote control. Alternatively, the device 104a, 104b, 300 remote control can only affect the management of light sources, identified in a given time interval.

Disclosed subject matter is applicable in scenarios with offices�V-plan where the device 104a, 104b, 300 remote control can be a personal device management employee in this office. In this case, the increased sensitivity specifically limited to cover only the luminaires located close to office space of a person in respect of personal control with lamps. Thus, according to variants of implementation of the device 104a, 104b, 300 remote control is limited to the control of the subset of light sources in a variety of light sources in the system 100 of the coded lighting. For example, the memory 306 of device 104a, 104b, 300 remote control may be able to save the preset limited number of identifiers. In General terms, the first identified light sources correspond to the light sources located close to (or at least having the greatest impact on) the device 104a, 104b, 300 remote control. It may be preferable that the device 104a, 104b, 300 remote control able to operate exclusively for such closely spaced light sources. In a typical scenario of a typical office workspace (or so-called volumetric workplace) can be associated only with 2-5 different light sources. Thus, it may be preferable that the device 104a, 104b, the control at a time can operate only within the limits referred to 5 light sources. The transmitter 308 may thus be configured to transmit additional commands exclusively in the case that identified the source of light 102 is contained in the subset. Alternatively, if the additional light source is detektirovanie, one of the stored identifiers may be deleted from the memory 306, thereby providing the ability to manage additional light source. It may be proposed to the user devices 104a, 104b, 300 remote control.

As disclosed above, the system 100 coded light may contain more than one device 104a, 104b, 300 remote control. Each device 104a, 104b, 300 remote control may be associated with a particular location or area in space in which a system 100 coded lighting. For example, each device 104a, 104b, 300 remote control can match the working space or volume the workplace, as disclosed above. Because the devices 104a, 104b, 300 remote control can be located relatively close to each other, they may be able to identify common source light 102 (e.g., the source 102 of the light having essentially the same distance to both devices 104a, 104b, 300 remote control�tion). Therefore, it may be preferable that the device 104a, 104b, 300 remote control is capable of using the interface 312 communication, exchange, in step 422, the information related to the identification of light sources and/or from each other, as schematically indicated by the reference position 110 in Fig.1. For example, the distance of the source light 102 (as specified by the received intensity of the coded light) may be determined by the ratio control between devices 104a, 104b remote control. As noted above, the power of the received coded light signal can be used to determine the impact of control that you can have appropriate lights. If the lamps have a high power, they are manageable and those that continue, with low power, only partly under control (for example, "enabled" interpreted as "included 50%" and the full stage blackout is the only stage of polozitelnoe). This is especially practical for open-plan offices and residential premises, where multiple users may be required to impact on the same fixtures. For example, if the relative distance between the light source and the device 104a remote control a length of x units and the relative distance between the light source and the device 104b di�remote control length y units then management relationship between the device 104a remote control and the device remote control 104b can be configured to y/x. In other words, if the relative distance between the light source and the device 104a remote control length 4 units and the relative distance between the light source and the device 104b remote control length 6 units, then the management device 104a remote control 60%, while the attitude control device 104b remote control 40%.

Fig.5 is an example of light transmission of the identifier in the system, containing four light source (indicated in the drawing the light source 1", ....., "the light source 4"). In each frame (still not identified the source of light) transmits one packet identifier (in the drawing indicated by rectangular blocks). The light sources used kadrirovannye the ALOHA Protocol and the drawing shows the transmission of two frames ALOHA (in the drawing indicated "framek"and frame "k+1"). As can be seen in the drawing, according to this example, there is a conflict between the package identifier of the light source 1 and the package identifier of the light source 2 in the framek. Thus, in the framekneither the light source 1 or the light source 2 can not be identified. From the remaining�I two light sources 3 and 4 in this example is supposed to what is the ID of the light source 3 is received by light detector device remote control with a higher level of intensity than the ID of the light sources 4. Thus, in the framekthe light source 3 successfully identified and, therefore, does not transmit the ID of the next time interval (i.e. framek+l). In the framek+l there is no conflict and at least a light source of the remaining light sources 1, 2 and 4, adopted with the high intensity, can be consistently identified.
