The technical field TO WHICH the INVENTION RELATES

The present invention relates to illumination of at least part of the building. More specifically, it relates to the management of the level of light at least part of the building with the help of electric light and window draperies.

The LEVEL of TECHNOLOGY

Modern buildings are often equipped with controllable window draperies, such as motorized curtains or blinds to control the amount of sunlight entering the building through open holes, usually Windows. Moreover, modern buildings are often equipped with controllable electric light that allows you to control the light level of the individual device or group of devices electric lights. The light level control is usually light regulators. Generally, it is advantageous to use daylight as much as possible. For the inhabitants of the building lighting daylight usually leads to improvement in health. From the point of view of the environment, as well as from the point of view of costs, optimal use of daylight for lighting the interior of the building can reduce energy consumption in the building by reducing the need for electric light. Moreover, the optimal control can also reduce the need for maintenance�STI in heating and cooling. In many cases, window hangings and the electric light are operated manually and/or independently from each other, which leads to sub-optimal use of daylight.

U.S. patent No. 7566137 discloses a system for providing illumination to provide the desired lighting parameters in the space of the building, where the space of the building is lit like daylight and electric light. The system comprises a sensor for measuring the light level in the space, many tunable light bulbs to Supplement the lighting and control system to control the level of light bulbs. The control system adapts to a given light level in advance, which leads to the desired parameters of the lighting space. Disclosed variants of implementation, which further comprising controllable window draperies to selectively change the amount of daylight entering the space.

However, in the existing level of technology there is a need for improvement.

Lighting systems of buildings prior art work consistently. With consistent work, first regulated by the amount of daylight from window draperies, then regulated electric light to the corresponding chip mode� a given value of a given level of illumination. Such systems often do not satisfy the user, because consistent work slow, and the wait time is unacceptable. If the user is not satisfied with the automatic control of the level of light, then there is a high level of risk that it will go to manual control that jeopardize the energy savings achieved through automatic control.

The IMPLEMENTATION of the INVENTION

Fig.1 schematically depicts a variant implementation of the lighting system for lighting the interior of the building 1, presented in this paper as a floor plan of the room. The lighting system includes a control system 2, functionally associated with the sensors 3 for detecting the light level of the interior, with the control devices 4 electric light to control the light level of electrical light sources with which they are associated, and the control devices 5 window drapery management window �papirovkoy 6 to change the acceptable level of daylight, transmitted through the transparent part, this paper is two Windows 8. Window drapery is usually curtains or blinds. In a variant implementation, the control system is made in the form of a control unit, functionally associated with a processing unit 7. The system further comprises an external sensor 9 detecting the level of daylight. External sensor 9 is depicted in a location outside the building. However, the sensor can also be placed inside in such a position, as for window drapery, where it can detect the level of daylight. The figure also depicts a sensor 10 presence of people in the room to detect the presence of a person in the room, and line 11 connection. The control system is depicted as a single unit. However, it is clear that it can be embodied in any suitable manner, usually as either a centralized system or as a distributed system. In a distributed system, the processing unit may be distributed through at least one or more control devices of the electric light, one or more control devices of window draperies and one or more user interfaces. The operation of the control system can be based on instructions provided by a computer program product 12, such as computer code in any form and lubimeishii.

It is also understood that the specific details of Fig.1 is provided for illustrative reasons. In General, the lighting system may be provided in connection with any type of a building containing any type of floor plan. The building can be subdivided into parts, for example, areas where the electric light zone is controlled independently. For example, four electric light source and two window Drapes can be managed jointly, on the basis of the average level of light detected by the two reading sensors of the interior. In General, the building can be subdivided into any number of parts where the light level is controlled, jointly, on the basis of the work of any number of window draperies and any number of electrical light sources, on the basis of sensor readings from any number of sensors of the interior. If more than one sensor is used for the joint management group for electrical light sources, can be generated a combined sensor signal. The combined signal may be the average signal, the weighted signal, or by any other suitable signal. The number of light fixtures and window draperies depends on the specific application.

Fig.2A and 2B are structural diagrams depict two variants of implementation of the General location of controls. Fig.2A depicts an implementation option of applying detsen�realizowanego management and Fig.2B depicts an implementation option of the use of centralized management.

Fig.2, input values or signals are received from three components: data input values extracted from 20 specified values; introductory value extracted from the sensor data from the sensor 21 of the interior; and input values extracted from the sensor readings from the external sensor 22. The values 20 may be based on a combination of user settings and other General settings management. Sensors are usually made in the form of photo-sensors that can detect the level of illumination. The level of illumination is usually expressed as a specified level Suite. On the basis of input sources 23, 23' electric light and window draperies 24, 24' are controlled by a control device, either in the form of fixed devices 25, 26, or a joint Central control device 27. In embodiments, the control device of the electric light control the level of dimming of lighting devices, and the device management window draperies controls the mechanism of window draperies.

In the depicted embodiment of the device control by electric light and the device management window draperies are functionally related to the 28, 29, so that the working information can be shared�, to the electric light was controlled on the basis of the received information from the window draperies and/or Vice versa.

Fig.3 depicts a simplified block diagram of carrying out the control scheme executed by the device management window draperies in the case where the control device of the electric light together with the device management window draperies has an overall operating information in the form of a status light level, so that window drapery can work depending on this status.

The flowcharts in Fig.3 and 4, "Yes" abbreviated as "d", and "no" abbreviated as "h".

The initial open circuit is set to detect whether the system window draperies:

30: set in automatic mode.

If Yes,

31: detecting whether there is the specified value or fully opened window drapery, and the electric light turned on.

If the window drapery is fully open, window drapery can't work to provide more light. Therefore, if the answer to the above conditions, "no", the system is instructed to go back to detect whether the automatic mode 30. If the answer to the above condition (31) is "Yes" then there is the following control sequence:

32: to Determine, muted electric�historical light;

if Yes,

33: to determine whether the light level in the room is higher than the target level specified target values. That is, it is determined whether the difference between the detected light level of the interior and a set value of the light level of the interior positive or negative. If the detected light level of the interior is higher than the set value of the light level of the interior, then:

34: to reduce the allowable level of window draperies.

If 32 is determined that the electric light is turned on, then:

35: is also determined if the level of light in the room is higher than the target level specified target values. However, in this case, if the light level is too high:

36: permissible level of window draperies falling slowly: otherwise:

37: permissible level of window draperies increases.

Fig.4A depicts a simplified General block diagram of carrying out the control scheme executed by the control device of the electric light in the case where the control device of the electric light does not accept information about the status of the device management window draperies.

The initial open circuit is set to detect whether the electric light:

40: set in automatic mode.

If Yes,

41: detecting whether �complying with the specified value.

If the answer to the above condition (41) is "Yes" then there is the following control sequence:

42: determining whether the light level in the room is higher than the target level specified target values. That is, it is determined whether the difference between the detected light level of the interior and a set value of the light level of the interior positive or negative. If the detected light level of the interior above the setpoint light level of the interior, then:

43: reduction of the level of light generated from electric light, for example, by increasing the level of darkness.

However, if the detected light level of the interior is not above the set value of the light level of the interior, then:

44: increase the level of generated electric power, for example, by reducing the level of darkness.

Fig.4B depicts a simplified General block diagram of carrying out the control scheme executed by the control device of the electric light in the case where the control device of the electric light receives information about the status of the device management window draperies, so that the electrical light sources can work depending on this status.

The initial open circuit is set to detect whether the electric light:

400: established in automatic mode.

If Yes,

401: detecting whether the specified value, or fully opened window drapery, and the electric light turned on.

If the answer to the above condition (401) is "Yes" then there is the following control sequence:

402: determining when to open the window drape at the maximum allowable level;

if Yes,

403: determining whether the light level in the room is higher than the target level specified target values. That is, it is determined whether the difference between the detected light level of the interior and a set value of the light level of the interior positive or negative. If the detected light level of the interior above the setpoint light level of the interior, then:

404: reducing the level of electric light, for example, by increasing the level of darkness.

However, if at 402 it is determined that a window Drapes are not open to the maximum allowable level;

405: also, it is determined whether the light level in the room is higher than the target light level specified target values. However, in this case, if the light level is too high:

406: the level of electric light is increased, for example, by reducing the level of darkness;

otherwise:

407: level electric�CSOs light increases gradually, for example, by gradually decreasing the level of darkness.

Further, disclosed in more detail two variants of implementation, in which the control system is implemented by a given cost function that minimizes the difference between the detected light level of the interior and a set value of the light level of the interior. In the following examples, the cost function contains, in addition to the difference between the detected light level of the interior and a set value of the light level of the interior, the level of energy consumption by electrical light sources, so the sources of electric light and window draperies are managed with a reduction in the difference between the detected light level of the interior and a set value of the light level of the interior, and reduction of energy consumption by electrical light sources.

The control device of the electric light and the device management window draperies can in embodiments be implemented for adaptive control of the light level, based on the algorithm of gradient reduction, which minimizes the cost function. The cost function can be constructed so as to contain a fraction of the difference in light level and energy consumption. In this paper, the difference in light level is also called as bug lights. Following EQ�of Ur. 1 and Ur. 2 adaptive reduce both the error light and power consumption:

Ur. 1

Ur. 2

where x(n) and w(n) represent the electric light settings and the settings window draperies, respectively. The parameter n is the approximate time. In a similar situation, n is replaced by the timet. Function e(n) expresses the difference between the preset value of the user and measured by the light level of the interior, thus, e(n) is the error light. Function E(n) is the energy consumption.μare positive constant that specifies the dimensions of adaptation. The equations, therefore, specify the amount by which the electrical light sources and window drapery change for each of the adaptive management cycle.

Error light can be further described as:

e(n)=y(n)-u

where u specifies the desired set value of the user, and y(n) is an indication of the sensor about the interior lighting. Interior lighting can be described as:

y(n)=dl(n)w(n)+x(n)

where dl(n)is the level of available daylight, a certain indication of the external light sensor. The energy consumption of the electrical light sources can be set as proportional tox(n)which leads to:

E(n)αx(n)αy(n)-dl(n)w(n)

Using the above �of alignment, Ur. 1 and Ur. 2 can be simplified to EQ. 3 and Ur. 4:

x(n)=x(n-1)-μ1e(n)-μ2x(n),Ur. 3

w(n)=w(n-1)-μ3e(n)dl(n)+μ4x(n), EQ. 4

The presence of x(n) and w(n) in both equations ensures that the control of electric light and window drapery integrated. Moreover, the control algorithm implementing the above SD. 3 and Ur. 4, allows parallel operation without the need for a sequential operation, even if the time constant for electric light and window draping variety. Parallel adaptive system will still work correctly because the correct parallel operation.

The control algorithm is based on the SD. 1 and Ur. 2 (or LVL. 3 and Ur. 4) adjusts the balance of reducing energy consumption and compliance with the set values of the user. This may cause the values of the user cannot be always completely satisfied to save energy. This situation happens when daylight is insufficient to meet the requirements of light level, and, consequently, the level of electric lighting should be increased significantly. In this case, the control system can set the light level to a lower level to conserve energy. It is not always acceptable to the user. In another embodiment, the implementation as described in about�Novo Ur. 5 and SD. 6 below, the satisfaction of specified values to the user is a priority, while energy consumption is reduced. In a variant implementation, this can be achieved by using adaptive reduction of the error of lighting and energy consumption as follows:

Ur. 5

Ur. 6

that, as in the case of Ur. 1 and Ur. 2, can be simplified to EQ. 7 and SD. 8:

x(n)=x(n-1)-μ1e(n), EQ. 7

w(n)=w(n-1)-μ3e(n)dl(n)+μ4x(n), EQ. 8

These equations control the lighting device simply seek to satisfy the specified values of the user (i.e. to reduce the error lights), however, the device management window draperies seeks both to reduce the error of light, and to compel the electric light to save energy by assuming the largest possible amount of light through the window to the electrical light sources respectively extinguished.

In this lighting system, the number of different control algorithms can be selected via the user interface, so responsible for the lighting system can choose either the management of the entire lighting system on the basis of a General algorithm or parts of the building, managed on the basis of different algorithms.

In other embodiments, the algorithm UE�of Alenia can be based on proportional control, where the conclusions of the control device of the electric light and the device management window draperies proportional to the difference between the detected light level of the interior and a set value of the light level of the interior, which is proportional to the function e(n) lighting bugs.

Fig.5 depicts a simplified block diagram of a control system implementing the control algorithm on the basis of EQ. 7 and SD. 8 in a variant implementation of Fig.2A, i.e. in a decentralized control system. Thus, each or group of electrical light sources and each or group of window draperies are controlled by a decentralized control device. In the illustrative version of the implementation, each device control by electric light, and each device control window draperies contains its own control unit.

The user, typically by using a user interface such as a remote control device, computer or wall interface, sets the desired light level of 50, u, for example, by setting the setpoint to the desired value Suite. The set value of the user input device 51 of the electric light and in the device 52 of the control window draperies. Additionally, the testimony of the Dutch�ka from the sensor 53 interior lights are input to both of the control device. The device 51 of the electric light determines the error light,eat the first stage 54 of the processing, and the error light sequence is used to determine the control variable electric light (for example, values that reduce the level of darkness)x(n)at the next stage, 55 processing, which uses EQ. 7.x(n)an output of source 56 electric light to set the level of light. Moreover,x(n)is the output 502 of the control device of window draperies. Altered levels of light affect the subsequent reading of the light sensor 57 of the interior.

In parallel, i.e. simultaneously or in parallel with, the work of electrical light sources, the device 52 of the control window Drapes also determines (or receives) the error light,eat the first stage 58 of the processing, and the error light is further used to determine the control variable window Drapes (e.g., magnitude, changing the position of the louvres), additionally on the basis of the adopted x(n), and the sensor readings from the external sensor 501, to determine dl(n).The control variable window draperies is determined at the next stage 59 processing using EQ. 8. w(n) is the output of window draperies 500 for establishing an acceptable level. Again, the modified level with�ETA will affect the following indications 57 sensor interior light.

Fig.6 depicts a simplified diagram of a control system implementing the control algorithm on the basis of EQ. 7 and SD. 8 in a variant implementation of Fig.2B, i.e., in a centralized control system. Thus, the Central processing unit controls the electrical light sources and window draperies by sending control settings.

As in the case of Fig.5, the user sets the desired light level of 50,u. The set value of the user is input to the Central unit 60 of the management, along with the sensor data from the sensor 53 interior lights and sensor readings from the external sensor 501 of light. The Central device 60 to control the illumination determines the error light,eat the first stage 54 of the processing. Error lighting and sensor readings from the external sensor is then used to determine the control variable electric lights x(n) and the control variable window Drapes w(n) at the next stage 61 processing, which uses EQ. 7 and SD. 8. Certain x(n) and w(n) are the output 62 of the electric light to set the level of light and the device 63 of the control window draperies for setting permissible levels. Altered levels of light affect the subsequent reading of the light sensor 57 of the interior.

Parallel work is obvious�and in this case, since the Central control unit works with two equations simultaneously.

Fig.7 depicts a graph showing the simulation results of the system in accordance with the options of implementing the present invention. This and the subsequent simulation is performed through the implementation of Fig.5 in MatLab. The figure depicts the proportion φ [Deluxe] light level from daylight and electric light, respectively, as a function of the maximum magnitude of Mdl[Suite] daylight. The graph depicts a situation in which the electric light is limited to 1000 Lux output with changeable daylight, when the installation user is 500 Lux. The graph shows the percentage of fluorescent light 70 and the proportion of electric light 71. As you can see, the more available daylight, the more reduced the share of electric light, which, in turn, reduces energy consumption. The electric light is used only when insufficient daylight.

Fig.8 depicts a graph showing the simulation results of the system in accordance with the variants of implementation of the present invention, similar to the schedule in Fig.7, except that the Figure depicts the proportion φ [Deluxe] daylight as a function of SP [Deluxe]. The graph depicts a situation in which the electric light is limited to 500 Lux. The graph shows the share of the daily Saint�80 and the share of electric light 81. As can be seen, when daylight is not available to satisfy the setpoint of the user, the electric light is used as little as possible.

Fig.9 depicts a graph showing the simulation run closed loop adaptive sequential system in comparison with the execution of a parallel system in accordance with the options of implementing the present invention. The figure depicts normalized part of a valid light Fφfor serial control 90 window draperies, serial control 91 electric light, parallel control 92 window draperies in accordance with the variants of implementation of the present invention and parallel control 93 electric light in accordance with the variants of implementation of the present invention, all of which are presented as a function of time n[t]. The figure depicts a situation in which the set value increases by 94. Changes to a specified value can be caused by a set value of the user or in response to detection of the occupancy sensor in the room of human presence.
