  Hereinafter, a control system according to an embodiment will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited to these embodiments.

(Embodiment)
A control system 100 according to the embodiment will be described. As shown in FIG. 1, the control system 100 is configured to control a plurality of devices. FIG. 1 is a diagram illustrating a configuration of the control system 100. As shown in FIG. 1, the control system 100 includes a plurality of lighting devices (1a, 1b, 1c, 1d, 1e, 1f, 1g, 1h, 1i) installed on the ceiling β side of a living room α which is an example of a predetermined space. ), The air conditioner 2, the wireless router 6, and the management device 8 have a configuration capable of communicating via the communication network N. Hereinafter, among the lighting devices (1a, 1b, 1c, 1d, 1e, 1f, 1g, 1h, 1i), when an arbitrary lighting device is indicated, it is referred to as “lighting device 1”.

  As shown in FIG. 1, the lighting device 1 is installed in each of the regions 9 in which the ceiling β is divided into, for example, nine. And the detection apparatus 3 is provided in the illuminating device 1e arrange | positioned in the center of the ceiling (beta). The detection device 3 is an environment information acquisition device that acquires environment information related to the environment of a living room α that is an example of a predetermined space. The size of one region 9 is, for example, 50 cm to several meters wide (square), but the size of the region 9 is appropriately determined according to the size and performance of the lighting device 1. Each region 9 into which the ceiling β is divided may not be the same size, and each region 9 may not be a square. For example, if it is a polygon such as a hexagon, the distances between the illumination devices 1 are equal as in the case of a square.

  The air conditioner 2 is installed at an appropriate interval on the ceiling β. In FIG. 1, there is one air conditioner 2, but a plurality of air conditioners 2 are installed in one living room α as will be described later. The air conditioners 2 are preferably installed at regular intervals, but may not be equally spaced. The reason why the number of the lighting devices 1 and the air conditioning devices 2 is different is that the ranges that can be covered by the lighting devices 1 and the air conditioning devices 2 are different, the sizes are different, and the costs are different. The number of the illuminating device 1 and the air conditioner 2 can be determined arbitrarily. In addition, when there are a plurality of air conditioners 2, the reference numerals of the air conditioners 2 are 2a, 2b, and 2c, respectively.

  Note that in this specification, a living room is a room where people are present. The living room may be a room where a plurality of people exist. Specifically, the living rooms are offices, factories, seminar venues, exhibitions, indoor stadiums, and the like. The living room may be a private home.

  The environmental information is information related to the environment of the living room. Further, the environmental information is information relating to a preferable environmental state in order for a person to act comfortably. Or environmental information is the information regarding the state of the environment where it is preferable to be controlled in order for a person to operate comfortably. Specifically, the environmental information will be described using detection data (heat source data, temperature, humidity, illuminance), which will be described later, as an example, but is not limited thereto.

  The illumination device 1 is, for example, a fluorescent lamp type LED (Light Emitting Diode). The detection device 3 of the illuminating device 1e detects a temperature distribution in which the room α is divided into a plurality of regions (here, 9 regions), for example, by a thermopile function. And the detection apparatus 3 of the illuminating device 1e transmits the heat source data which shows the presence or absence of a heat source to the management apparatus 8 based on the detected temperature distribution. A wireless LAN or the like is used for transmission, but it may be transmitted by wire. The floor of the living room α is a place where a person who is a target to be detected as a heat source exists.

  The air conditioner 2 is, for example, an air conditioner such as an air conditioner (the indoor unit is illustrated in FIG. 1). The outdoor unit is installed in a predetermined place for each air conditioner 2 or in common for a plurality of air conditioners 2. In FIG. 1, the air conditioner 2 and the management device 8 are connected by wire, but may communicate wirelessly.

  The wireless router 6 receives the heat source data transmitted from the detection device 3 and transmits it to the management device 8 via the communication network N. The communication network N is constructed by a LAN (Local Area Network) and may include the Internet in part.

  As will be described later, the management device 8 has the function of a control device and may be called a server. The management device 8 generates control data for controlling the lighting device 1 and the air conditioner 2 based on the heat source data and the like sent from the wireless router 6. The management device 8 transmits the generated control data to the lighting device 1 and the air conditioner 2. The lighting device 1 performs dimming control of the LED based on the control data. The air conditioner 2 controls temperature, humidity, wind power, and wind direction based on the control data. Therefore, the management apparatus 8 can control both lighting and air conditioning, and can provide a space in which comfort and energy saving are considered for the people in the room.

  As is apparent from the above description, the lighting device 1e on which the detection device 3 is mounted not only detects the temperature distribution of the room α, but also performs dimming control of the LED of the device itself. Although the illuminating device 1e has the detection apparatus 3, it has a function equivalent to the other illuminating devices 1. FIG.

  Moreover, the detection apparatus 3 may be installed in or near the air conditioner 2. The detection device 3 may be installed separately from the lighting device 1 or the air conditioning device 2. However, since the detection device 3 is integrated with the lighting device 1, it is easy to attach and remove the detection device 3, and there is an advantage that it is not necessary to prepare a space for attaching the detection device 3.

  Next, the apparatus main body 120 to which the illuminating device 1 and the illuminating device 1e are attached is demonstrated using FIG. FIG. 2 is an external perspective view showing an example of the lighting device 1.

  As shown in FIG. 2, the lighting device 1 is, for example, a fluorescent lamp type LED lighting fixture, and includes a straight tube type LED lamp 130.

Among these, the socket 121a has power supply terminals (124a1, 124a2) for supplying power to the LED lamp 130.

  The socket 121b also has power supply terminals (124b1, 124b2) for supplying power to the LED lamp 130. Thereby, the apparatus main body 120 can supply the power from the power source to the LED lamp 130.

  On the other hand, the LED lamp 130 has a translucent cover 131 and caps (132a, 132b) provided at both ends of the translucent cover 131, respectively. Among these, the translucent cover 131 is formed, for example with resin materials, such as an acrylic resin, and is provided so that an internal light source may be covered. The illuminating device 1 e includes the detection device 3 adjacent to or inside the translucent cover 131.

  Further, the base 132a is provided with terminal pins (152a1, 152a2) connected to the power supply terminals (124a1, 124a2) of the socket 121a, respectively. The base 132b is provided with terminal pins (152b1, 152b2) connected to the power supply terminals (124b1, 124b2) of the socket 121b, respectively. When the LED lamp 130 is mounted on the apparatus main body 120, each terminal pin (152a1, 152a2, 152b1, 152b2) is connected to the apparatus main body 120 via each power supply terminal (124a1, 124a2, 124b1, 124b2). Electric power can be supplied. Thereby, the LED lamp 130 irradiates light to the outside through the translucent cover 131. The detection device 3 operates with power supplied from the device main body 120.

Can be done. Note that the communication method of the wireless module 301 may be not only wireless communication but also wired communication such as Ethernet (registered trademark) cable or PLC (Power Line Communications). The wireless module 301 operates under the control of a communication control program executed by the device controller 315.

  The temperature distribution sensor 311 is a thermal detection element that detects the temperature distribution in the living room α by detecting infrared rays. Since the temperature distribution sensor 311 can detect the surface temperature of a person or an object by using a thermal detection element, it can detect the temperature of a place near a person. That is, the temperature distribution sensor (human detection means) 311 detects whether or not a person is present near the detection target space. The thermal detection element has an absorption layer that absorbs light and converts it into heat, and outputs a temperature change of the absorption layer to the outside as an electrical signal. Examples of the thermal detection element include a thermopile, a bolometer, a pyroelectric element, and a diode whose voltage-current characteristics change.

Alternatively, the device controller 315 may be constructed by hardware such as an IC. For example, the device controller 315 controls the timing at which the temperature distribution sensor 311, the illuminance sensor 312, and the temperature / humidity sensor 313 detect the temperature and the like, and processes data detected by each sensor. For example, the device controller 315 generates heat source data indicating the presence or absence of a heat source from the temperature distribution data output from the temperature distribution sensor 311. The device controller 315 transmits detection data including heat source data to the management device 8.

  First, the layout management DB 8001 will be described. Here, FIG. 7 is a diagram exemplarily showing information stored in the layout management DB 8001. The layout management DB 8001 manages the layout information of the lighting device 1 or the air conditioner 2 as shown in FIG.

  As shown in FIG. 7A, the layout information includes one room α divided into 54 areas as an example, and an apparatus ID for identifying the lighting apparatus 1 as an LED lighting apparatus in each area 9. Are managed in association with each other. The alphabets a to f and the two-digit numerical value are the device ID. Among these, the nine areas 9 on the upper left starting with the device ID “a” correspond to the nine areas in FIG. That is, FIG. 1 shows a part of the living room α. The actual living room α has six blocks whose device IDs start with a, b, c, d, e, and f. Each block is divided into nine areas, and is divided into a total of 54 areas. Such division of the area 9 is an example, and it may be divided into any number of blocks, and one block may be divided into a number of areas other than 9 areas.

  In FIG. 7A, the alphabetic x and the two-digit numerical value are the device ID of the air conditioner 2.

The control guide management DB 8002 manages a first control guide management table as shown in FIG. In the first control guideline management table, the control content of the control target unit 20 is managed in association with the heat source field. For example, if the heat source field is “1” indicating that there is a heat source, it indicates that there is a person in the area 9. In this case, in the first control guideline management table, the light amount is set to 100% so as to maximize the light amount of the LED so that a person can work comfortably. On the other hand, when the heat source field is “0” indicating that there is no heat source, since there is no person in the area 9, the light quantity of the LED is set to 60% in order to realize energy saving. Note that 100% is only an example of a comfortable light amount, and 60% is an example of a light amount that realizes energy saving and does not make work difficult. For example, when the heat source field is “1”, the light amount is 90%, When “0” is “0”, the light quantity may be set to 50%. As long as the light quantity of the heat source field “1” is higher than the light quantity of the heat source field “0”, both may be any percentage.

  The control guide management DB 8002 manages a second control guide management table as shown in FIG. In the second control guideline management table, control guidelines for air conditioning are managed in association with human density and “temperature gap + humidity”. The temperature gap is the difference between the target value when the air conditioner 2 controls the temperature and the temperature detected by the temperature distribution sensor 311. According to the second control guideline management table of FIG. 8B, for example, the human density is 1 to 19%, the temperature is in the range of -T1 ° C to -T2 ° C with respect to the target value, and the humidity is less than H1%. In this case, the air conditioner 2 is controlled so that the temperature becomes + 2 ° C. with respect to the target value. If the humidity is H1% or higher even in the same temperature range with the same human density (1 to 19%), the air conditioner 2 is controlled dry.

  In the second control guide management table, control guidelines for air conditioning as shown in FIG. 8B are set for each human density according to the combination of the temperature gap and the humidity. Therefore, the management device 8 can finely control the air conditioning. For example, when the human density is high, the management device 8 can control the air conditioner 2 before the person feels uncomfortable because the temperature of the region 9 actually increases or the humidity changes due to the human body temperature. That is, feedforward control is possible. Therefore, comfort can be further improved.

  It should be noted that the method of dividing the human density is merely an example for explanation, and the human density may be divided more finely, or the width of the human density of each partition may be uneven.

  Further, the control guideline management DB 8002 manages an air conditioning set value table (see FIG. 25) as a third control guideline management table. Details of the air conditioning set value table will be described later.

  Next, the control area management DB 8003 will be described. Here, FIG. 9 is a diagram exemplarily showing information stored in the control area management DB 8003. A control area management table as shown in FIG. 9 is managed in the control area management DB 8003. In the control area management table, the area ID is managed in association with the apparatus ID of the air conditioner 2. The area ID is a device ID of the lighting device. As can be seen from FIG. 7A, the device ID of the air conditioner 2 is associated with the region ID of a 3 × 3 region 9 centered on the air conditioner 2.

  Note that 3 × 3 is merely an example, and 4 × 4 may be used, or the air conditioner closest to each region 9 and the region 9 may be associated with each other. For the lighting device 1, since one region 9 is associated with one lighting device 1, a control area management table is not necessary, but a region where one lighting device 1 is not limited to just below the lighting device 1. When the presence / absence of the heat source 9 is used, a control area management table as shown in FIG. 9 is prepared.

  Next, the area information DB 8004 and the mass / area correspondence DB 8005 will be described with reference to FIG. FIG. 10 is a diagram exemplarily showing information stored in the area information DB 8004 and the mass / area correspondence DB 8005. The area information DB 8004 manages an area information table as shown in FIG. In the area information table, the coordinate information of each area 9 is registered in the area ID of the area 9. The coordinate information of each area 9 is, for example, the coordinates of diagonal vertices. Thereby, the management apparatus 8 can determine where each area is from where. For example, the region 9 of region ID = a11 is a square of 0 to 100 cm in the X direction and 0 to 100 cm in the Y direction. The size of the area 9 is an example.

  Next, the mass / region correspondence DB 8005 will be described with reference to FIG. A mass / region correspondence table as shown in FIG. 10B is managed in the mass / region correspondence DB 8005. The mass / region correspondence table is a table for associating the detected mass with the region 9. Therefore, the area ID is registered in the mass / area correspondence table in association with the mass ID. The mass ID is an ID for identifying the detected mass. For example, it is a number that does not overlap, a combination of the ID of the lighting device 1 and a number or alphabet. One square ID corresponds to only one area ID, but one area ID may correspond to a plurality of square IDs.

  Next, returning to FIG. 6, each functional configuration of the management device (control device) 8 will be described. The transmission / reception unit 81 illustrated in FIG. 6 includes a reception unit 81a and a transmission unit 81b. For example, the reception unit (reception unit) 81 a receives detection data (detection result of the temperature distribution sensor 311) from the detection device 3. The transmission unit (transmission means) 81b transmits control data to the lighting device 1 and / or the air conditioner 2.

  For example, the collation unit 82 collates the layout information shown in FIG. 7A and the heat source data shown in FIG. 14 described later. Thereby, the presence or absence of a person for each area 9 is determined.

  The generating unit (control unit) 84 refers to the collation result of the collation unit 82 and the first control guide management table, and generates control data indicating the amount of light for the lighting device 1. Further, the generation unit 84 refers to the verification result of the verification unit 82 and the second control guide management table based on the heat source data and the humidity data detected by the temperature / humidity sensor 313, for example, and the air conditioner for the air conditioner 2 Control data is generated.

  The grid conversion processing unit 85 converts the heat source data transmitted by the temperature distribution sensor 311 into heat source data of the area 9 of the living room α. Details will be described later.

  For example, the storage / reading processing unit 89 reads data from the storage unit 8000 or stores data in the storage unit 8000.

  Here, human density will be described. FIG. 11 is a diagram exemplarily showing human density. In FIG. 11A, 3 × 3 regions 9 are shown for the sake of explanation. Each 3 × 3 area 9 is set in the control area management DB 8003 of the management apparatus 8 as a range (a range in which temperature, humidity, etc. are controlled) by one air conditioner 2. The human density is also calculated with respect to the range in which one air conditioner 2 performs air conditioning.

  In FIG.11 (b), the black circle was shown in the area | region 9 (area | region with a heat source) where the person was detected. Since people are detected in three of the nine regions 9, the human density is calculated as (3 ÷ 9) × 100 = about 33%. No matter how many people are actually in the area 9, if a person is detected in the area 9, it is counted as one person.

  Each 3 × 3 area 9 in which the human density is calculated is a range in which one air conditioner 2 performs air conditioning. However, temperature data and humidity data of nine areas 9 are transferred from the detection device 3 to the management device 8. Has been sent. The management device 8 determines the average of the temperature data of the nine regions 9 as the environmental value of the nine regions 9. Regarding the humidity, humidity data detected by the detection device 3 closest to the air conditioner 2 may be used as the environmental value, or an average of humidity data detected by several detection devices 3 may be used as the environmental value.

  Hereinafter, processing or operation of the management apparatus 8 will be described.

  Here, the management device 8 generates control data for controlling the lighting device 1e based on various data detected by the lighting device 1e, and transmits the control data to the lighting device 1 and the air conditioner 2. Thus, processing in which the lighting device 1 and the air conditioner 2 perform light control and air conditioning will be described. For simplification of description, processing of the lighting device 1e including the detection device 3, the other lighting device 1, and the air conditioner 2 among the plurality of lighting devices 1 will be described.

  FIG. 12 is a sequence diagram exemplarily showing processing of the management apparatus 8. As shown in FIG. 12, first, the detection unit 32 of the lighting device 1e detects the temperature distribution of each region 9 in the living room α (step S21).

  Next, the determination unit 33 determines whether the temperature is within a predetermined range value (for example, 30 ° C. to 35 ° C.) for each region 9, so that the generation unit 34 obtains the heat source data based on the determination result. Generate (step S22).

  Here, generation of heat source data will be described. FIG. 13A is a conceptual diagram exemplarily showing a temperature distribution, and FIG. 13B is a conceptual diagram exemplarily showing heat source data. As a result of detecting the temperature of each region 9 by the detection unit 32, it is assumed that the temperature distribution of the nine regions 9 is in the state shown in FIG. The generation unit 34 generates heat source data as shown in FIG. As can be seen by comparing FIG. 13A and FIG. 13B, the heat source data is indicated by heat source presence / absence information indicating the presence / absence of the heat source, and the temperature is within a predetermined range value (for example, 30 ° C. to 35 ° C.). Region 9 is represented as “1”, and region 9 having a temperature below 30 ° C. and greater than or equal to 36 degrees is represented as “0”.

  Returning to FIG. The detection part 32 of the illuminating device 1e detects the illumination intensity of the vicinity of the illuminating device 1e, temperature, and humidity (step S23).

  And the transmission / reception part 31 of the illuminating device 1e transmits detection data with respect to the management apparatus 8 (step S24). The detection data includes heat source data generated in step S22, temperature / humidity data (including temperature data used to generate the heat source data) and illuminance data indicating the result detected in step S23. . Thereby, the transmission / reception part 81 of the management apparatus 8 receives detection data. The temperature data used for generating the heat source data is preferably for each detection mass, but may be an average of the temperatures of some or all of the regions 9. Thereby, it can suppress that the load of the management apparatus 8 increases. In this case, the averaged temperature of each region 9 is treated as the same.

  FIG. 14 shows heat source data obtained by synthesizing heat source data transmitted from a plurality of lighting devices 1 e having the detection device 3. FIG. 14 is a conceptual diagram of heat source data indicating the presence or absence of all heat sources in one room α. The heat source data shown in FIG. 13B corresponds to the heat source data of the upper left block B in FIG. The heat source data in FIG. 14 is also actually given by a distorted detection mass.

  Next, the grid conversion processing unit 85 of the management apparatus 8 reads the mass / area correspondence table from the mass / area correspondence DB 8005 and converts the heat source data into heat source data corresponding to the area 9 (step S24-2). . Details will be described with reference to FIG.

  Next, the storage / read processing unit 89 of the management device 8 reads the layout information shown in FIG. 7A from the layout management DB 8001 (step S25).

  And the collation part 82 collates the layout information shown by Fig.7 (a), and the heat source data shown by FIG. 14 (step S26). By this collation, for example, in the area 9 where the lighting device 1a is present in the layout information, since the heat source field of the heat source data is “1”, it is determined that there is a “heat source”.

  Next, the storage / read processing unit 89 of the management device 8 searches the first control guideline management table of the control guideline management DB 8002 using “1” and “0” indicating the presence or absence of the heat source in the heat source data as search keys. Thus, the corresponding light quantity is read (step S27-1).

  Further, the storage / reading processing unit 89 of the management apparatus 8 reads the second control guideline management table from the control guideline management DB 8002 and reads the control area management table from the control region management DB 8003 (step S27-2).

  And the production | generation part 84 produces | generates the control data which show the light quantity with respect to the illuminating device 1 (step S28). Moreover, the production | generation part 84 produces | generates the control data of the air conditioner 2 (step S28). Thus, based on one detection data transmitted in step S24 (based on the same detection data), both control data for the lighting device 1 and control data for the air conditioner 2 can be created. Therefore, even when the two devices of the lighting device 1 and the air conditioner 2 are controlled, the number of times the management device 8 receives the detection data detected by the detection device 3 can be reduced to half. Moreover, since the same detection data is used, it becomes easy to take consistency of operation | movement of the illuminating device 1 and the air conditioner 2. FIG.

  Next, the transmission / reception part 81 transmits each control data with respect to the illuminating device 1 (step S29-1, S29-2). On the other hand, the transmission / reception unit 31 of the lighting device 1e receives control data. Moreover, the transmission / reception part 51 of the illuminating devices 1 other than the illuminating device 1e receives control data.

  Next, in the illuminating device 1e, the control part 35 produces | generates the control signal for outputting to the control object part 20 as an LED lamp based on control data (step S30-1). Similarly, the control part 55 of the illuminating devices 1 other than the illuminating device 1e produces | generates the control signal for outputting to the control object part 20 as an LED lamp based on control data (step S30-2).

  The control unit 35 outputs a control signal to the control target unit 20 (step S31-1). The control unit 55 outputs a control signal to the control target unit 20 (step S31-2).

  Thereby, the light quantity of the control object part 20 as an LED lamp is controlled (step S32-1, S32-2).

  The transmission / reception unit 81 of the management device 8 transmits control data to the air conditioner 2 (step S33). In contrast, the transmission / reception unit 51 of the air conditioner 2 receives control data.

  As a result, the temperature, humidity, air volume, and wind direction of the control target unit 20 as an air conditioner are controlled (step S34).

  For example, in FIG. 13, since it is determined that there is no heat source in the area 9 with the area ID a22 (indicated by “0”), the area is in accordance with the first control guideline management table of FIG. The amount of light of the illumination device 1 in the area 9 whose ID is a22 is controlled to 60%. On the other hand, in FIG. 13, since there is a heat source directly below the region 9 with the region ID a21 (indicated by “1”), the region ID is a21 according to the first control guide management table of FIG. The amount of light of the illumination device 1 in the area 9 is controlled to 100%.

  As a result, when the heat source is detected because there is a person, the light quantity of the LED is maximized, and when the heat source is not detected because there is no person, the light quantity of the LED is reduced, thereby realizing energy saving. Can do. In addition, when there is a person, the amount of light increases, so that the comfort of the person can be improved.

  A method for determining the presence or absence of the heat source described in step S22 of FIG. 12 will be described.

  FIG. 15 is a flowchart schematically showing the flow of heat source data generation processing. FIG. 16A is a conceptual diagram showing a temperature distribution, and FIG. 16B is a conceptual diagram of heat source data indicating the presence or absence of a heat source.

  First, the generation unit 84 of the management device 8 extracts the region 9 from which the determination unit 33 does not determine whether the temperature is within a predetermined range (for example, 30 ° C. to 35 ° C.) from the temperature distribution data (step S41). .

  Then, the determination unit 33 determines whether or not the temperature of the region 9 extracted in step S41 is within a predetermined range (step S42). For example, when an electric pot (water heater) is installed in the region 9 where the lighting device 1 with the device ID a13 is installed, as shown in FIG. For example, the temperature of the region 9 may be 60 ° C. In such a case, even if a heat source is present, it is not within the range of human heat sources (for example, 30 ° C. to 35 ° C.).

  Next, when the determination unit 33 determines in step S42 that it is within the predetermined range (Yes), it determines that there is a heat source (step S43). In this case, as shown in FIG. 16B, the heat source data is set to “1” indicating that there is a heat source.

  On the other hand, if the determination unit 33 determines that it is not within the predetermined range (No), it determines that there is no heat source (step S44). In this case, as shown in FIG. 16B, the heat source data is set to “0” indicating that there is no heat source.

  Then, after the processing in steps S43 and S44, the determination unit 33 determines whether or not the determination on whether or not the temperature is within the predetermined range is completed in all the regions 9 (step S45). If it is determined in step S45 that all the regions 9 have been determined (Yes), the processing in step S22 in FIG. 12 ends. On the other hand, if it is determined in step S45 that the determination of all the regions 9 has not been completed (No), the process returns to step S41.

  In this way, according to the processing shown in FIG. 15, even if a heat source is present, if it exceeds the range of the heat source by a specific object (for example, a human), the heat source is not handled. Thus, the presence of a person can be detected more accurately. Thereby, there exists an effect that an energy saving can be implement | achieved more correctly.

  As described above, the heat source data as shown in FIG. 16 is obtained. However, since the shape of the mass of the heat source data is actually distorted depending on the mounting angle of the temperature distribution sensor 311, the following inconvenience occurs.

  First, the more temperature distribution sensors 311, the more accurately the temperature of each region 9 can be detected. However, if the temperature distribution sensor 311 is large, the cost increases. Therefore, it is considered to install a plurality of temperature distribution sensors 311 in one lighting device 1. However, in that case, it is necessary to install the temperature distribution sensor 311 in a state where the temperature distribution sensor 311 is not perpendicular to the floor surface but is inclined to the floor surface. Since a plurality of temperature distribution sensors 311 are installed in a limited place that is integrated with or in the vicinity of the lighting device 1, the temperature detectable range 501 of one temperature distribution sensor 311 is expanded if no inclination is provided. This is because they cannot.

  FIG. 17 is a diagram exemplarily illustrating a relationship between the number of temperature distribution sensors 311 and the detectable range 501. In FIG. 17A, since the temperature distribution sensor 311 is one and is installed perpendicular to the floor surface, the detectable range 501 is a square (or a rectangle). In FIG. 17B, there are two temperature distribution sensors 311. However, since the temperature distribution sensors 311 are installed in a state where an inclination is given to the floor surface, each detectable range 501 has a shape distorted by trapezoidal distortion (trapezoid). It becomes. In FIG. 17 (c), there are four temperature distribution sensors 311. However, since each of the temperature distribution sensors 311 is installed with an inclination to the floor surface, each detectable range 501 is extended only by one diagonal line of a square. It becomes a warped shape (a shape close to a rhombus). This is because the temperature distribution sensor 311 is installed in a state rotated by 90 ° with respect to FIG.

  On the other hand, each area 9 of the living room α is divided into a square or a rectangle. For this reason, when the several temperature distribution sensor 311 is installed in the one illuminating device 1, it is necessary to match the heat source data of the distorted shape with the area | region 9 of the room (alpha).

  FIG. 18 is a diagram exemplarily showing detection areas detected by two temperature distribution sensors 311. FIG. 18A shows a detectable range 501 detected by the two temperature distribution sensors 311. In FIG. 18A, a total of six illumination devices 1 are illustrated, and one illumination device 1 has two temperature distribution sensors 311. One temperature distribution sensor 311 further includes a 4 × 4 thermopile sensor. That is, one temperature distribution sensor 311 can detect 16 temperatures in parallel. A detectable range 501 of one thermopile sensor is referred to as a detection mass 502 (an example of a sensor detection range).

  Since the temperature distribution sensor 311 is not installed perpendicular to the floor surface, the detectable range 501 and the detection mass 502 are distorted in a trapezoidal shape. Therefore, the heat source data transmitted from the detection device 3 to the management device 8 is also obtained in such a shape. It becomes difficult to use the heat source data distorted in a trapezoid as it is for the temperature of each region 9 of the living room α. Therefore, as shown in FIG. 18B, the heat source data is converted into a shape without distortion. Alternatively, the presence or absence of the heat source in each detection mass 502 of the heat source data is made to correspond to each region 9 of the living room α. That is, a plurality of squares in FIG. 18B indicate the respective regions 9 of the living room α.

  FIG.18 (c) is the figure which superimposed FIG.18 (a) and FIG.18 (b). The grid conversion processing unit 85 of the management device 8 associates each area 9 in FIG. 18B with the detection mass 502 in FIG. 18A, and the detection mass 502 of the thermopile sensor that overlaps the area 9 in each area 9. Set the heat source data (with or without heat source). Since only one detection mass 502 is not necessarily included in one area 9, when a plurality of detection masses 502 correspond to one area 9, the logical sum of presence or absence of a heat source is set in the area 9. The

  FIG. 19 is a flowchart illustrating a flow of a grid conversion process in which the grid conversion processing unit 85 of the management apparatus 8 associates the detected grid 502 in the detectable range 501 with the area 9. The process of FIG. 19 is executed in S24-2 of FIG.

  First, the grid conversion processing unit 85 sets 1 to the sensor number n of the temperature distribution sensor 311 (step S51). The sensor number n is a serial number assigned to the temperature distribution sensor 311 for easy processing.

  Next, the grid conversion processing unit 85 sets 1 to the grid number m (step S52). The mass number m is a serial number assigned to the detection mass 502 formed by each of the plurality of thermopile sensors included in one temperature distribution sensor 311.

  The grid conversion processing unit 85 determines which region 9 the detected mass 502 of the focused thermopile sensor overlaps (step S53). This determination is made based on whether or not the center coordinate O of the detection mass 502 of the thermopile sensor is included in the region 9. The center coordinate O will be described with reference to FIG.

  The square conversion processing unit 85 sets the presence / absence of the heat source in the heat source data of the detection mass 502 of interest to the area 9 determined to correspond in step S53 (step S54).

  The cell conversion processing unit 85 determines whether m is the last cell number (step S55). When the determination in step S55 is No, the grid conversion processing unit 85 increases m by one (step S56). Then, steps S53 to S55 are repeated.

  If the determination in step S55 is Yes, the grid conversion processing unit 85 determines whether n is the last sensor number (step S57). When the determination in step S57 is No, the grid conversion processing unit 85 increases n by one (step S58). Then, steps S52 to S57 are repeated. If the determination in step S57 is Yes, the process in FIG. 19 ends.

  If the management apparatus 8 (or the detection apparatus 3) performs the process of FIG. 19 as a process of associating the area 9 with the square, and the square number m is converted into a square ID that does not overlap, the area ID of the area 9 It is possible to create a mass / region correspondence table for associating the mass ID with each other. Therefore, after the lighting device 1e is installed on the ceiling, the grid conversion processing unit 85 can convert the heat source data having a distorted shape into the heat source data of the area 9 with reference to the mass / area correspondence table.

FIG. 20 is a diagram illustrating the center coordinates O of the detection mass 502 detected by the thermopile sensor. The position (x _o , y ₀ ) of the thermopile sensor on the ceiling β is given, for example, with the corner of the ceiling as the origin (0, 0). A height Z of the ceiling β is also given. It is assumed that the depression angles θx and θy with respect to the floor of each thermopile sensor are given. θx is a depression angle in the X direction, and θy is a depression angle in the Y direction.

From these, the center coordinate O of the detection mass 502 detected by one thermopile sensor is given by (x ₀ −Ztan θx, y ₀ −Ztan θy). The depression angles θx and θy are determined by the attachment angle of the detection device 3 to the illumination device 1e and the central angle of the detection direction given by the manufacturer of each thermopile sensor (angle when installed perpendicular to the installation surface). . That is, since the center angle of the detection direction of each thermopile sensor is given by a manufacturer or the like, θx and θy can be obtained by adding the attachment angle δ of the detection device 3 to the illumination device 1e to this value. In the figure, θx and θy are shown in a state in which the attachment angle δ is included. The position (x ₀ , y ₀ ) of the thermopile sensor, the depression angles θx, θy, and the attachment angle δ are information related to the position of the detection mass 502 formed by the thermopile sensor.

  Since the coordinates of each region 9 are values obtained by equally dividing the size of the room α vertically and horizontally, it can be easily obtained when the size of the room α is given by a design drawing or actual measurement. Accordingly, the grid conversion processing unit 85 can determine where the center coordinate O of each thermopile is included in the region 9.

  Instead of comparing whether the center coordinates O of the detection mass 502 are included in the region 9, for example, it may be compared whether any one or more of the four corners of the detection mass 502 are included in the region 9. If it is determined whether or not all four corners are included in each region 9, the number of regions 9 with heat sources tends to increase, which is effective when it is desired to control the lighting, air conditioner, etc. by estimating the possibility that there are people. is there.

  Further, when calculating the center coordinate O of the detection mass 502, the height at which a person is present may be used instead of the height Z of the ceiling β. For example, the height where people are is about "Z-110cm". This makes it easy to associate the detection mass 502 with the area 9 where people are actually present.

  As described above, the heat source data obtained by the detection device 3 is actually obtained in a distorted shape, but can be converted into heat source data of each region 9 of the room α by the process of FIG.

  As described above, the process of FIG. 19 is a logical sum process in which it is determined that there is a heat source when at least one center coordinate of the detection mass 502 is included in a certain region 9. On the contrary, even if the center coordinates of two or more detection masses 502 are included in a certain region 9, the number of heat sources in the region 9 is one. This can reduce erroneous determination that there is no person in the area 9. For example, this process is useful when the area 9 is wide.

  The center coordinate O may be the center of gravity in addition to the center of one detection mass 502. Further, the center coordinate O may be within the range of the detection mass 502, not the center or the center of gravity. This is because the heat source can be detected within the range of the detection mass 502.

  Further, the processing of FIG. 19 may be performed by the detection device 3 in addition to the management device 8. Or the illuminating device 1 may perform.

  Next, generation of control data in step S28 in FIG. 12 will be described. FIG. 21 is a flowchart showing a flow of processing in which the generation unit 84 generates control data relating to the light amount of the fluorescent lamp type LED lighting fixture for the lighting device 1.

  The generation unit 84 takes out one unprocessed lighting device 1 (step S61). The unprocessed lighting device 1 is a lighting device 1 for which control data has not been determined.

  Next, the production | generation part 84 refers to the heat source data of the area | region 9 with the extracted illuminating device 1 (step S62). Since the device ID of the lighting device 1 is the same as the region ID, the presence / absence of the heat source can be read from the heat source data.

  And the production | generation part 84 judges whether there exists a heat source in the area | region 9 with the illuminating device 1 (step S63). That is, it is determined whether or not “1” is set in the heat source data.

  When the heat source of the region 9 where the lighting device 1 is “1” (Yes in step S63), the generation unit 84 determines the light amount of the lighting device 1 to be 100% and generates control data (step S64). This 100% is set in the control guideline management table.

  When the heat source of the region 9 where the lighting device 1 is not “1” (No in step S63), that is, the heat source is “0”, the generation unit 84 determines the light amount of the lighting device 1 to be 60% and obtains control data. Generate (step S65). This 60% is set in the control guideline management table.

  Next, the generation unit 84 determines whether or not control data has been generated for all the lighting devices 1 (step S66). When determination of step S66 is No, the production | generation part 84 returns to step S61 and repeatedly performs the process of steps S61-S65. When the determination in step S66 is Yes, the generation unit 84 ends the process illustrated in FIG.

  In this way, control data for the lighting device 1 that is a fluorescent lamp type LED lighting fixture can be generated based on the presence or absence of a heat source (the presence or absence of a person) for all the lighting devices 1.

  FIG. 22A is a flowchart showing the flow of the air conditioning control process, that is, the process of generating the air conditioner control data for the air conditioner 2 by the generating unit 84 (S28). FIG. 22A is a flowchart for performing solar radiation presence determination and air conditioning control from information indicating lighting on / off and information indicating the presence or absence of a person.

  The generation unit 84 starts the environment sensing process (S71) and the illumination ON / OFF detection process (S72) in parallel.

  In the environment sensing process (S71), the process shown in FIG. 22B is performed. FIG. 22B is a flowchart showing the environment sensing process (S71). That is, the generation unit 84 counts the time t from the start of processing, and waits until the count time t becomes equal to or greater than the threshold time a (> 0) (No in S81). When the count time t is equal to or greater than the threshold time a (Yes in S81), the generation unit 84 transmits a detection instruction for detecting the presence / absence of a person and the room temperature to the detection device 3. The temperature distribution sensor (human detection means) 311 of the detection device 3 detects the presence / absence distribution of people (see FIG. 13B) according to the temperature distribution of the detection target region in accordance with the detection instruction. 3 temperature / humidity sensor 313 detects the room temperature of the detection target region in accordance with the detection instruction (S82). The detection device 3 transmits the detection result of the temperature distribution sensor 311 (detection result of the presence / absence of a person) and the detection result of the temperature / humidity sensor 313 to the management device 8 (S83). When the management device 8 receives the detection result of the temperature distribution sensor 311 and the detection result of the temperature / humidity sensor 313 from the detection device 3, the management device 8 resets the count time t to zero and returns the process to S81.

  In the illumination ON / OFF detection process (S72), the process shown in FIG. 22C is performed. FIG. 22C is a flowchart showing the illumination ON / OFF detection process (S72). That is, the generation unit 84 counts the time t from the start of processing, and waits until the count time t becomes equal to or greater than the threshold time a (> 0) (No in S91). When the count time t becomes equal to or greater than the threshold time a (Yes in S91), the generation unit 84 transmits a detection instruction for detecting the ON / OFF state (lighting / extinguishing state) of the lighting device 1 to the detection device 3. The device controller 315 of the detection device 3 detects the lighting / extinguishing state of the lighting device 1 (LED lamp 130) according to the detection instruction (S92).

  For example, the device controller 315 of the detection device 3 acquires the detection result from the illuminance sensor 312, and the lighting device 1 (LED lamp 130) is turned on / off based on the detection result of the illuminance sensor 312 (illuminance in the region 9). Is detected. Based on the detection result of the illuminance sensor 312, the device controller 315 of the detection device 3 can detect that the illumination device 1 is lit if the illuminance of the corresponding region of the detection device 3 is higher than a predetermined threshold. If the illuminance of the corresponding area of 3 is lower than a predetermined threshold, it can be detected that the lighting device 1 is turned off.

  Alternatively, the device controller 315 of the detection device 3 detects an LED drive signal (drive current or the like) supplied from the device controller 315 of the lighting device 1 to the control target device 319 (LED lamp 130), and detects the detected LED drive. Based on the signal, the lighting device 1 (LED lamp 130) is turned on or off. The device controller 315 of the detection device 3 can detect that the lighting device 1 is lit if the level of the LED drive signal exceeds a predetermined threshold based on the detected LED drive signal. If the level does not exceed the predetermined threshold, it can be detected that the lighting device 1 is turned off.

  Alternatively, the device controller 315 of the detection device 3 acquires illumination control information via the antenna 302a, the antenna I / F 302, and the wireless module 31, and based on the acquired illumination control information, the illumination controller 1 (LED lamp 130). Detects lighting / extinguishing status. The device controller 315 of the detection device 3 can detect that the lighting device 1 is turned on if the lighting control information is information that instructs the lighting device 1 to be turned on, and the lighting control information instructs the lighting device 1 to be turned off. If it is information, it can be detected that the lighting device 1 is turned off.

  The device controller 315 generates information (lighting ON / OFF information) indicating the detection result, and transmits the lighting ON / OFF information to the management device 8 (S93). When the management device 8 receives the lighting ON / OFF information from the detection device 3, the management device 8 resets the count time t to zero and returns the process to S91. The illumination ON / OFF detection process (S72) can be performed for each of the partial areas A to C in the illumination control area IA.

  After confirming that the reception of the detection result of the temperature distribution sensor 311 and the detection result of the temperature / humidity sensor 313 from the detection device 3 and the reception of the illumination ON / OFF information from the detection device 3 have been completed, the generation unit 84 Judgment processing (S73) is performed.

  In the determination process (S73), the process shown in FIG. 22D is performed. FIG. 22D is a flowchart showing the determination process (S73). In other words, the generation unit 84 acquires the illumination ON / OFF information received by the management device 8 and the detection result of the temperature distribution sensor 311 (detection result of the presence / absence of a person) (S101). The generation unit 84 performs solar radiation presence / absence determination processing (S102) for determining the presence / absence of solar radiation based on the ON / OFF state of the lighting device 1 indicated by the lighting ON / OFF information and the detection result of the temperature distribution sensor 311.

  In the solar radiation presence / absence determination process (S102), the process shown in FIG. 23 is performed. FIG. 23 is a flowchart showing solar radiation presence / absence determination processing (S102). That is, the generation unit 84 starts counting time and determines whether or not the ON / OFF state of the lighting device 1 indicated in the lighting ON / OFF information is an OFF state (light-off state) (S111). If the ON / OFF state of the lighting device 1 indicated in the lighting ON / OFF information is the ON state (lighting state) (No in S111), the generation unit 84 determines that there is no solar radiation (S113). The determination result is held in the RAM 803 and the process is terminated. When the ON / OFF state of the lighting device 1 indicated in the lighting ON / OFF information is in the OFF state (light-off state) (Yes in S111), the generation unit 84 may have solar radiation, so the temperature distribution sensor ( Based on the detection result of (human detection means) 311, it is determined whether or not a person is present in the area corresponding to the air conditioner 2 in the living room α (S 112). If there is no person in the area corresponding to the air conditioner 2 in the room α (No in S112), the generation unit 84 determines that there is no solar radiation (S113), and stores the determination result in the RAM 803 for processing. Exit. If there is a person in the area corresponding to the air conditioner 2 in the room α (Yes in S112), the generation unit 84 determines that there is solar radiation (S114), and stores the determination result in the RAM 803 for processing. finish.

  Returning to FIG. 22 (d), the generation unit 84 controls the air conditioning control data (in the region corresponding to the room α, which is an example of the predetermined space) according to the result of the solar radiation presence / absence determination process (S 102) and the control guideline information ( An air conditioning setting process (S103) for generating an air conditioning setting value) is performed.

  In the air conditioning setting process (S103), the process shown in FIG. 24 is performed. FIG. 24 is a flowchart showing the air conditioning setting process (S103). That is, the generation unit 84 refers to the determination result held in the RAM 803 and determines whether or not there is solar radiation in the solar radiation presence determination process (S102) (S121).

  When it is determined that there is solar radiation in the solar radiation presence / absence determination process (S102) (Yes in S121), the generation unit 84 refers to the air conditioning setting value table as the third control guideline management table and sets the air conditioning when there is solar radiation. A value is selected (S122). The generation unit 84 selects an air conditioning set value when there is solar radiation corresponding to the air conditioner to be controlled (indoor units x11, x12, x21, x22) from the air conditioning set value table. The generation unit 84 determines the air conditioning set value to be transmitted to the air conditioner 2 to the air conditioning set value selected in S122, and generates control data including a setting instruction for the air conditioning set value (S126).

  Here, in the air conditioning set value table, when it is determined that the amount of solar radiation is greater than normal, it is determined that the room temperature will increase in the future, and the set temperature of the air conditioner 2 should be set to a value that takes into account the temperature increase. It has been created in consideration of the points.

  For example, in the living room α, a worker working in the living room α comes to the office and the lighting device 1 and the air conditioner 2 (for example, the indoor units x11 to x22 shown in FIG. 7A) start operating. When it is 10:00 am, the sunlight from the window is bright, sufficient illuminance is ensured in working, and the lighting device 1 is turned off by the worker.

  In the control system 100, the lighting device 1 is turned off even though it is detected by the environmental sensing (S71) that there is one or more people in the area 9 that the lighting device 1 should originally illuminate. Is detected due to the influence of solar radiation, it is determined that the lighting device 1 is not required to be turned on and is turned off. In other words, the weather is good and the temperature is expected to rise in the future. Comparing a day with a large amount of solar radiation with a day with a small amount of solar radiation, it is known that there is a difference of 0.5 degree in 2 hours in some data. It is known that the air conditioner 2 starts to air-cool when it exceeds a certain temperature in summer, but on a day with a lot of solar radiation, the building is warmed by solar radiation and the room temperature rises, so that air-cooling starts late. For a certain period of time, a person must be uncomfortable.

  Therefore, when it is determined that there is solar radiation, the air conditioning setting value including a lower temperature than in the case without solar radiation can be changed so that the air cooling can be performed before going forward and becoming uncomfortable. The set temperature set in the air conditioner 2 is a difference from the current setting as in the air conditioning set value table of FIG. 25 (b) and the case where values are specified as in the air conditioning set value table of FIG. 25 (a). There is a way to set. Although this setting depends on the setting of the system, it may be a unit for each air conditioning indoor unit or a grouped indoor unit. 25A and 25B illustrate a case where the air conditioning setting value is set in the air conditioner 2 in units of the indoor units x11, x12, x21, and x22 (see FIG. 7A). .

  Returning to FIG. 24, when it is determined that there is no solar radiation in the solar radiation presence / absence determination process (S102) (No in S121), the generation unit 84 determines whether or not solar radiation has disappeared (S123). If it is determined that there is no solar radiation in the previous S121 and it is determined that there is no solar radiation in this S121, the generation unit 84 maintains the current air conditioning setting value, assuming that the solar radiation has already disappeared (No in S123). (S124), that. If it is determined in the previous S121 that there is solar radiation and it is determined in this S121 that there is no solar radiation, the generation unit 84 determines that the solar radiation has disappeared (Yes in S123) and sets the air conditioning setting value when the solar radiation disappears. Set or return to the original air conditioning setting value (S125). When setting to the air conditioning set value when the solar radiation disappears, the generating unit 84 corresponds to the controlled air conditioner (indoor unit x11, x12, x21, x22) from the air conditioning set value table when the solar radiation disappears. Select the air conditioning setpoint. The generation unit 84 determines the air conditioning setting value to be transmitted to the air conditioning apparatus 2 as the air conditioning setting value maintained in S124 or the air conditioning setting value selected in S125, and generates control data including a setting instruction for the air conditioning setting value. Generate (S126).

  Here, the air-conditioning set value table is created in consideration of the point that it is determined that a drastic increase in room temperature cannot be expected in the future when the amount of solar radiation disappears.

  For example, in the above example, when it becomes 13:00, the day starts to change, and the lighting device 1 is turned on again, it is determined that further outside air and the accompanying increase in room temperature cannot be expected. Or set the specified value or change amount again. The set temperature set in the air conditioner 2 is different from the current setting as in the case where the value is specified as in the air conditioning set value table in FIG. 25C and the air conditioning set value table in FIG. There is a way to set. Although this setting depends on the setting of the system, it may be a unit for each air conditioning indoor unit or a grouped indoor unit. 25C and 25D illustrate a case where the air conditioning set value is set in the air conditioner 2 in units of the indoor units x11, x12, x21, and x22 (see FIG. 7A). .

  Returning to FIG. 22D, the management device 8 transmits the control data (air conditioning set value) generated by the generation unit 84 to the air conditioning device 2 (S104).

  Returning to FIG. 22A, when the air conditioning apparatus 2 receives the control data (air conditioning set value), the air conditioning set value is changed according to the control data, and the room α which is an example of the predetermined space with the changed air conditioning set value. Is air conditioned (S74).

  As described above, in the embodiment, in the control system 100, the generation unit (control unit) 84 of the management device 8 turns on / off the lighting device 1 that illuminates the predetermined space and the temperature distribution sensor (human detection unit). Based on the detection result 311 and the control guideline information (air conditioning set value table), the presence or absence of solar radiation is determined. The generation unit 84 predicts a future increase in room temperature according to the determination result, and generates control data related to air conditioning in the predetermined space. The management device 8 transmits the control data generated by the generation unit 84 to the air conditioner 2. Thereby, since the presence or absence of the solar radiation to the predetermined space can be determined without using the solar radiation amount sensor, the control system 100 can be configured without incorporating the solar radiation amount sensor. That is, the control system 100 for improving energy saving and comfort in air conditioning control can be realized at low cost.

  In the embodiment, in the control system 100, the generation unit (control unit) 84 of the management device 8 has a combination of the lighting / light-off state of the lighting device 1 and the detection result of the temperature distribution sensor (human detection unit) 311. It is determined whether or not there is solar radiation according to the continuing time. For example, the generation unit (control unit) 84 determines that there is solar radiation on the condition that the lighting device 1 is turned off and a person is present for a predetermined time or longer. Thereby, necessary control can be performed in a state where the influence of solar radiation is confirmed, and comfort can be improved.

  It should be noted that when determining the presence or absence of solar radiation, the determination may be made by further considering the time conditions under which solar radiation is expected to occur. For example, as shown in FIG. 26, in the solar radiation presence / absence determination process (S102), before S111, the generation unit 84 determines whether or not the current time belongs to the detection target time zone (S131). The generation unit 84 acquires the current time, accesses the storage unit 8000 to acquire the time condition DB 8006, and includes the detection target time zone condition and the current time as illustrated in FIG. And according to the comparison result, it is determined whether or not the current time belongs to the detection target time zone. If the current time does not belong to the detection target time zone (No in S131), the generation unit 84 ends the process. If the current time belongs to the detection target time zone (Yes in S131), the generation unit 84 performs the processing after S111. FIG. 27 is a setting example of detection target time zone conditions used for determination of the detection target time zone (S131).

  For example, a time condition is added because it is determined that there is solar radiation and the air-conditioning setting is not changed even though the temperature is not expected to rise due to solar radiation under some condition. The setting method may be a method of directly setting the management apparatus 8 via a UI or the like, or a method of the management apparatus 8 acquiring information from the outside via the communication network N and automatically setting the information. In FIG. 27A, the sunrise sunset time is set, and the sunrise time zone is set as the detection target time zone. In FIG. 27 (b), a time zone in which the worker is working and the room α is operating is set. This is because even if the presence of a person is detected outside the operating hours, the operation is not performed. In Fig. 27 (c), in addition to setting the time zone for determining whether there is solar radiation for the operating time (here, the name is the temperature rise time), measures are taken to save energy by turning off the lights during the lunch break time zone. In the room α as it is implemented, it turns off even if there is a person regardless of whether or not there is solar radiation. Such a time zone is set as a non-detection time zone.

  For example, in the case where the detection target time zone condition is set in FIG. 27C, the lighting device 1 is turned off when the room α is cleaned by the cleaning company at 7:00 to 7:30 in the early morning. However, since it is not the detection target time zone (No in S131 of FIG. 26), the solar radiation presence / absence determination is not performed. Similarly, when the lighting device 1 is turned off after 12:00, the presence / absence of solar radiation is not determined because the non-detection time zone is set.

  As described above, when determining whether or not there is solar radiation, it is possible to prevent erroneous detection other than the influence of solar radiation by further considering the time conditions under which solar radiation is expected to occur.

  Alternatively, when determining the presence or absence of solar radiation, the determination may be made by further considering the duration of the state in which it is determined that there is solar radiation. For example, as shown in FIG. 28A, in the solar radiation presence / absence determination process (S102), the generation unit 84 sets an initial value “0” to the parameter T for counting the duration time before S111 ( S141). After S112, the generation unit 84 increments the parameter T (S142), and determines whether the parameter T is equal to or greater than the threshold time α (S143). If the parameter T is less than the threshold time α (No in S143), the generation unit 84 returns the process to S111. If the parameter T is equal to or greater than the threshold time α (Yes in S143), the generation unit 84 determines that there is solar radiation. (S114) The determination result is held in the RAM 803, and the process is terminated. Alternatively, for example, as shown in FIG. 28B, S131 similar to FIG. 26 may be performed before S141.

  In this way, in order not to detect that the lighting device 1 is not turned off due to solar radiation under certain conditions, the lighting device 1 is turned off for a certain period of time and a person is present. Check and judge that there is solar radiation. That is, one combination (combination of the light-off state and the presence of a person) among a plurality of combinations formed by the lighting / light-off state of the lighting device 1 and the detection result (the presence / absence of a person) of the human detection means. Whether or not there is solar radiation is determined according to the duration of the period. Thereby, it can avoid misjudging that the lighting apparatus 1 is extinguished and the temporary state in which a person existed is the lighting apparatus 1 being extinguished due to the absence of solar radiation.

  For example, when the workers in the target area leave the room α all at once, the lighting device 1 is turned off and there are people because the timing of leaving the worker's room α is slightly different or stops a little. It is possible to avoid erroneously determining that the state temporarily occurs as the lighting device 1 is turned off due to the absence of solar radiation. In addition, even if the lighting device 1 is turned off by mistake, a state in which the lighting device 1 is turned off and a person is present temporarily occurs, but this state is caused by the absence of solar radiation. It is possible to avoid misjudging that 1 is turned off.

  Alternatively, the air conditioning set value table referred to in S122 and S125 of FIG. 24 may be determined such that different air conditioning set values (temperatures) can be set for each time as shown in FIG.

  For example, the summer setting in which the normal setting is 27 degrees is taken as an example. FIG. 29A shows the air conditioning set value to be changed, and FIG. 29B shows the setting change amount with respect to the current set temperature. For solar radiation in the early morning (for example, 7:30), the influence on the rise in the room temperature is very low, so 27.0 (± 0) degrees is set. On the other hand, many workers in the target area started to work, and after 8:00 am, when the room temperature was naturally rising, when the indoor temperature increased further due to solar radiation, the room temperature also increased rapidly and increased by 1 in 1 hour. Often, room temperature rises above 0 degree. Even if the room temperature only changes by 0.5 degrees, people feel uncomfortable, so fine control is required. Since the effect of room temperature increase due to solar radiation in the morning and the effect of room temperature increase due to solar radiation in the afternoon or evening are different, the temperature increase is predicted according to the time and the set temperature is set.

  In this way, when it is determined that there is solar radiation, control data for the air conditioning setting value is generated based on the air conditioning setting value corresponding to the solar radiation occurrence time, so the influence of solar radiation according to the occurrence time is determined in detail. It can be controlled and comfort can be improved.

  Or, when setting the air conditioning setting values in S122 and S125 of FIG. 24, different air conditioning setting values can be set for each area when the room α, which is an example of the predetermined space, is divided into a plurality of areas. Good. When it is determined that there is solar radiation, the change of the air conditioning setting value to the plurality of air conditioning indoor units x11 to x22 (see FIG. 7A) in the room α is changed for each area in the room α where the room temperature rises due to solar radiation. In consideration of temperature fluctuation, it is possible to determine the presence or absence of control and its set value. FIG. 30 shows a flowchart of the air conditioning setting process when the room α is divided into an east area, a west area, a central area, and other areas as areas where the temperature rise due to solar radiation in the room α may be different, and the air conditioning settings are different. In FIG. 30, the flow when it is determined that there is no solar radiation (No in S121) is the same as the flow after S123 in FIG. If it is determined that there is solar radiation (Yes in S121), the generation unit 84 determines whether the layout position of the controlled air conditioner 2 (air conditioning indoor units x11 to x22) is in the west area, the central area, the east area, or any other area. It is determined whether it is within the area (S161). The other areas include areas other than the west area, the central area, and the east area when the room α is divided into a plurality of areas including the west area, the central area, and the east area.

  If the layout position of the air conditioning device 2 to be controlled is “west area”, the generation unit 84 refers to the air conditioning setting value table and selects the air conditioning setting value when there is solar radiation corresponding to the layout position “west area”. (S162). If the layout position of the air conditioning device 2 to be controlled is “central area”, the generation unit 84 refers to the air conditioning setting value table and selects the air conditioning setting value when there is solar radiation corresponding to the layout position “central area”. (S163). If the layout position of the air conditioning device 2 to be controlled is “east area”, the generation unit 84 refers to the air conditioning setting value table and selects the air conditioning setting value when there is solar radiation corresponding to the layout position “east area”. (S164). If the layout position of the air conditioning device 2 to be controlled is “other area”, the generation unit 84 refers to the air conditioning setting value table and selects the air conditioning setting value when there is solar radiation corresponding to the layout position “other area”. (S165).

  At this time, as shown in FIG. 31, the air conditioning set value table referred to in S162 to 165 may be determined so that different air conditioning set values can be set for each area. Furthermore, as shown in FIG. 31, different air conditioning set values (temperatures) may be determined for each time so as to be settable.

  For example, the temperature rise due to solar radiation in the room α varies greatly depending on the position and material of the window of the room α, the presence / absence of blinds, the direction, and the positional relationship with surrounding buildings. In the case shown in FIG. 30 and FIG. 31, there are windows on the three sides, east, north, and west, and the sun goes into the room α from the east window in the morning. In the evening, the sun goes into the room α from the west window. However, the temperature rise due to the insertion of the east and west suns is different, the temperature rise due to solar radiation in the morning in the east is 0.3 degrees per hour, and the temperature rise due to solar radiation in the evening in the west is 0.8 degrees per hour. There is a tendency. FIG. 31A shows the air conditioning set value to be changed, and FIG. 31B shows the setting change amount with respect to the current set temperature.

  Thus, it is determined whether or not there is solar radiation for each of a plurality of areas into which the predetermined space is divided, and control data is generated according to the air conditioning setting value corresponding to the presence of solar radiation. Considering the tendency of the effects of the air conditioning, more appropriate air conditioning settings can be implemented, and comfort can be improved.
