The technical FIELD TO WHICH the INVENTION RELATES.

The invention relates to an automatic lighting setup for network-based lighting, in particular to create lighting that follows the man.

PRIOR art

A lighting concept that follows a man, can be found in numerous sources of literature, films and advertising. Currently used solution to determine which lights should turn on is to watch whether two lamps next to each other in physical space, but it's not very productive, for example, in the situation when two lines are parallel, but separated by a few bushes, lights turn on as soon as the lamp detects nearby pedestrians; then the lights on the parallel route is also included, what is not necessary. The same can be said about the fixtures located on two different floors or separated by a thin wall.

The INVENTION

The objective of the invention is to provide a system and method for automatic light settings.

The problem is solved by the invention set forth in the independent claims. In addition, embodiments of disclosed in zavisimykh claims.

The basic idea of the invention is to configure the lighting in the network of tubes, so that the lamp in the network adjust their light emission depending on the presence in its immediate surroundings and the detected presence surrounded by other lamps in the network. In accordance with a variant embodiment of the invention, the lamp may also be taken into consideration previous templates enable existing detectors presence for the correction of its light emission. More specifically, the invention is based on the anticipation that by analyzing patterns of detection by the detectors in lamps networks lamps, it is possible to see which bulbs are next to each other in the context of how likely the passage of a person under the specified lamp, provided that at the present time one passes under a different light. In accordance with the embodiment of the invention, the analysis can be performed by creating a cyclical neural network of lamps, in which the cyclical neural network, all of the quantity of light emitted by each lamp in the network is both the input and the output component of the network. Of course, also possible and other methods of analysis. The invention can automatically adjust the lighting pose the CTV network of lamps for a specific region in which lamps are before people get to a certain area.

A variant embodiment of the invention provides a system for automatic configuration of the lighting, and the system contains

- a network of lamps, each lamp is connected to the detector and capable of receiving signals from other lamps and/or sensors in the network, and the received signal indicates activity detected by the presence detector connected to the lamp, which transmits the signal, while

- each lamp adjusts its light emission depending on the signal received from the other lamps and results of measurement of its presence detector. In the network each lamp can contain its own detector presence, but also one presence detector can be shared by several lamps, for example, a group of four adjacent lamps. In addition, there may be provided more detectors presence than lamps, so that the lamp could be connected not only to one but to two or more detectors of the presence, or presence detectors, which are not connected to the lamp itself, may be combined. Presence detector connected to the lamp may be adapted to detect the presence and/or movement of people. The network between all lamps can be the t to be formed as a wire, and wirelessly. The network signal can be sent from one lamp to physically close with her lamp, but can also be provided to send the signal to all the lamps in the network, for example, by switching.

The lamp can adjust its light emission by performing the following steps:

- receive as input levels of activity from other lamps and measuring their presence detector,

processing the received input data, and

- correction light radiation depending on the processing.

The activity level of the lamp can be represented by a quantitative indication within a predetermined range, and this quantitative indicator of the activity detected is connected to the light detector presence.

Taken from another lamp the level of activity may contain a history of the activities detected by means connected to the light detector presence,

processing the received input may include receiving information from the history of the activities detected by the detector, to detect motion of a person, and

- light emission can be adjusted on the basis of a certain movement of the person.

Therefore, each bulb can save is aktivnosti, detected by the presence detector connected to the lamp, and activity from other detectors of the presence of the order could be executed analysis of historical data about activity for information about how the person is moving under the presence detectors. For example, if the level of activity of the first lamp is reduced and the activity level of the second adjacent lamp located next to the first lamp increases, the analysis of the trajectories of activity levels taken from both lamps under which a person moves in the direction from the first lamp to the second, can be obtained information about what people may soon enter into the area of the presence detector connected to the third lamp, which is located next to the second light network of lamps. The process information may also be accelerated if the received input data is filtered, for example, the strength of the radio signal and/or a time signal, transmitting the level of activity from the lamp. For example, input data can be filtered so that the processed signals are taken into account only signals with a signal strength that exceeds a predetermined value, or a time that is lower than a predetermined value. This provides the ability to process only the input data, taken from lamps that are in close proximity, and acceleration information, as the number of received input data can be reduced.

In addition, a variant embodiment of the invention relates to a method for automatic configuration of the lighting in the network of tubes, containing the following:

- reception of signals from other lamps in the network, and the received signal indicates activity detected by the presence detector connected to the transmitting signal lamp,

- taking measurements of presence detector connected to the above-mentioned lamp, and

- correction light radiation lamp, depending on the signals received from other lamps and measurement of presence detector connected to the said lamp.

The method can be implemented as a control algorithm for light radiation network of the lamps and, therefore, for automatic lighting configurations. It can be implemented in lamps or in the Central control unit for a lamp which is adapted for centralized control of lighting, created through a network of lamps.

Processing the received input data may include processing the input weighting function in which all inputs are weighted, and the weights are continuously adjusted depending on the activity, detected one or more presence detectors. Weighting provides the option of adjusting light emission of the lamp in accordance with the activity under other lamps and motion or presence of a person under a different light.

Correction weight values depending on the activity detected by one or more presence detectors, may contain:

- weight gain of two or more lamps, if presence detectors, connected to the lamps, detect activity within a predefined period of time, and/or if the activity levels of these lamps operate in accordance with the same template, or

- reducing the weight of two or more lamps.

Therefore, light emission of the lamp is increased if, for example, presence detectors adjacent lamps detect increased activity. Conversely, if the detectors of the presence of adjacent lamps do not show increased activity, the light emission lamp can be reduced, because it is obvious that the light no man there.

Processing the received input data may also include processing the input data to a sigmoidal function, radial basis function or activation function of multivariable logistic function. Typically, these functions are used in the art is different neural networks and may also be suitable and to provide the appropriate output for the correction light radiation lamp.

The function used for processing the input data may further comprise a delay time through the inclusion of one or more lamps, which is pre-defined delay time.

An additional variant embodiment of the invention relates to a lamp, which can be adapted for use with a system in accordance with the invention and as described above, the lamp contains:

the source of light,

a communication unit for establishing network connections and communications with other lamps,

detector presence,

- a storage device that stores the configuration of the lamp and the program to control the activity of the lamp depending on the input data received from other lamps, and measurement of the presence detector, and

a processing unit for executing stored in a storage device programs. This lamp can be included in the system as a physical object, and it allows quick and easy installation system for automatic lighting configurations in accordance with the invention. The communication unit of the lamp may be adapted to automatically create a network of connections with neighboring lamps, both wired and wirelessly. The presence detector can be configured to allow the flexible use and installation of the lamp.

A variant embodiment of the invention provides a computer program that triggers the processor to perform a method in accordance with the invention and as described above.

In accordance with an additional embodiment of the invention, a recording medium that stores a computer program in accordance with the invention, can be provided, for example, CD-ROM, DVD, memory card, floppy disk, storage device on the Internet, or similar media that is appropriate to store a computer program for optical or electronic access.

In more detail, the invention will be described below with reference to examples of embodiments. However, the invention is not limited to these illustrative examples of embodiments.

BRIEF DESCRIPTION of DRAWINGS

Fig.1 depicts an implementation option sist what we to automatically adjust the lighting in accordance with the invention;

Fig.2 depicts a first variant implementation of the bulb, which can be used in the system depicted in Fig.1; and

DETAILED DESCRIPTION of embodiments

In subsequent, similar in functionality or identical elements have the same reference numbers.

Fig.1 depicts a system 10 for automatic lighting configurations in the network of the lamps 12, each of which is connected to the detector 14 of the presence or movement in accordance with the invention. Lamps 12 are arranged in a rectangular grid, for example, can be installed on the stairs. It should be noted that in principle, the present invention is applicable to any network topology, and it is not limited to a rectangular grid. Each lamp 12 can communicate with its immediate neighbors in the grid, as well as with other lamps in the grid, because the network is configured to switch the message, i.e. a message sent from the first lamp to the second lamp in the grid, may be directed through several lamps.

Each lamp has a quantitative indicator within a predetermined range, for example from 0 to 1 (but the quantitative measure may be different), which determines how much of the Holy is Titus lamp (0 means off, and 1 means full brightness). Each lamp has regularly updates its current activation by obtaining a normalized weighted value activity detected through its detector 14 presence (which also displays the quantitative index within a specified interval, or simply returns the value 0, or 1, or any other two random measure). This update can occur both synchronously and asynchronously. The detector 14 presence capable of detecting the presence and movement of people and arranged in such a way that it covers the area under the lamp 12, which is also illuminated by the lamp 12.

In addition, each lamp 12 is configured to transmit its level of activity in the network so that other lamps could take the level of activity as input. The level of activity is sent through the signal and, for example, can also be implemented as a quantitative indicator within a predetermined range from 0 to 1, which indicates activity as detected by the presence detector connected to the lamp. The level of activity can be transmitted periodically by each lamp, each lamp transmits a signal containing the level of activity on all other lamps in the network. In addition, each lamp 12 is adapted to maintain the historical record of activity levels and to share this story with the shipment of the level of its activity so that the receiving lamp could determine the trajectory of activity as detected by the presence detector lamp, transmitting the history of activity levels. History of activity levels allows the lamp to get from it the information and are better able to adjust its light emission in accordance with the movement of the person.

In the network each lamp 12 receives as input the activity levels of all other lamps mesh and dimensions of the detector 14 of presence connected to the lamp 12. Each lamp 12 may filter the received input data, for example, by assessing the strength of the radio signal and/or the travel time of the signal transmitted from the other lamp. In particular, the input data from the lamps located far from the host lamp, can be ignored, because the activity detected by such lamps may have a minimal effect or no influence on the local configuration of the light receiving lamp. Filtering has the advantage that the amount of information that will be processed through the lamp may be reduced, and therefore, the process of obtaining information from the received input data can the be speeded up. Each lamp 12 processes the filtered in a certain way the input data and depending on the processing adjusts its light emission in the form of output data. Processing of input data can be performed by applying a function to the data input and generating the appropriate output for the correction of emitted light. Applied function may be a function of education, which provides information of the accepted histories of the level of activity detected by the detector presence of other lamps in the network. In specific embodiments of the invention applied function can be a function that is typically used in a chain of neural networks, such as the normalized weighted sum, a sigmoidal function, radial basis function or activation function of multivariable logistic function.

Fig.2 depicts a block diagram of a variant of implementation of the lamp in accordance with the invention. The lamp 12 is implemented as a physical object and contains the detector 14 presence, such as PIR (passive infrared sensor), CCD (charge coupled device), an audio sounder, controllable light source 16, the chip 18 communication, storage device 20 and the microcontroller 22. The microcontroller 22 is the Central control unit of the lamp 12 and performed the program, stored in a storage device 20 which provides means for adjustment of the brightness or light radiation control source 16 of the world. Controllable light source 16 receives data from the microcontroller 22, the signal correcting its light emission. The microcontroller 22 receives as input the measurement data from the detector 14 presence and data from the chip 18 links, which are connected with other lamps 12 in the network of tubes, as shown in Fig.1. Data from the chip connection are levels of activity, transmitted through all of the lamps 12 network. The program configures the microcontroller 22 for processing the received input data and to generate an appropriate signal for correcting light emission of the light source 16. The program can implement one of the above the above functions, for example, a typical function used in artificial neural network, in particular a chain of neural networks.

Fig.3 depicts a block diagram of an additional variant of the implementation of the lamp in accordance with the hardware implementation of the function used to process the input data. Hardware functionality can be implemented, for example, by chip ASIC (specialized integrated circuit) or FPGA (programmable gate array). In the depicted embodiment, the storage device is about 20 and the microcontroller 22 of the option exercise, is depicted in Fig.2, replaced the hardware implementation of the containing block 24 processing weights, X weighting functions W1, W2, ... WX, weighing X input data, i.e. measurement of the detector 14 presence and X-1 activity levels X-1 lamps network, with appropriate weights, and the block 26 summation and normalization for summing the weighted input data and normalization of the summation. Block 24 processing weight handles the correction signals from the received input data for functions W1 WX...weighing. In addition, the block 24 processing weight displays the activity levels of lamps X-1, which were taken from the chip 18 communication through a network of lamps on the appropriate weighting functions, i.e., the activity level of the lamp 1 to the function W2 weighting, the activity level of the lamp 2 to the function W2 weighting and so on. Block 24 processing weight periodically updates current inclusion depending on the results of measurements of the detector 14. Block 24 processing weight also regularly updates the weight for the activity levels of other lamps in the network. This is done by block 24 processing weight using the following measurements.

If the detectors of the presence of two lamps noticed activity at the same time or right after each other, the weight of these two lamps are used for weighting the activity level of each other, increases. E is whether there is a difference in time then, of course, can be used another rule updates, depending on what kind of lamp notices the activity first.

The activity levels of the two lamps are compared: if their activity levels correspond to the same pattern, for example, if one of them is high(low), while the other high(low), or if both their derivatives activation have positive(negative) value, the weight should be increased.

These rules should be understood to mean that if they are not applied at any point in time, the weight of the lamps used for weighing must be reduced. Processing weight as described above results in a lighting system, for which the lamp can be placed randomly, and they will independently automatically adjust its configuration for ignition of the light before passing man and slowly reduce the brightness behind the man.

The main problem to be solved by this procedure, is that if someone wants to install a lighting system for a given area and wants the light was switched on before people get to the specified area, then that person should determine what kind of light should be turned on, if a given sensor is available activation, and must clearly explain in which direction the floor is the user. However, the configuration above is automatically configured by means of the invention. The first foresight conducive to the invention, is that by analyzing patterns of presence through various detectors online presence lamps can be found, what bulbs are next to each other, in the context of how likely that person will soon pass under the specified lamp, provided that she/he now goes under a different light. Second, the anticipation is that the analysis can be performed by creating a chain of neural network in which the entire amount of light emitted by each lamp, is output, and the output component of the network. The third minor understanding is that if the presence detection and the lamp form a physical object, the connection between the detector and the lamp automatically.

The invention can be used in all types of lighting systems, in which the lighting system must predict where people will go, and turn on the light in advance so that people could see where she/he goes. However, the invention can also be used in other situations, such as decorative or artistic system in which the system is and, somehow follows the user, for example through, decorative lights, video or computer images projected on a wall or ceiling or other output, such as sound and water.

At least some of the functionality of the invention can be performed by hardware or software. In the case of the variant implemented in software tools, one or more standard microprocessors or microcontrollers may be used for processing one or more algorithms that implement the invention.
