Description

  The present invention relates to a straight tube type LED illumination lamp and system.

  By detecting the presence or absence of a person in the room, various controls can be automated depending on the presence or absence of the person. For example, a lighting device that automatically turns on by detecting the presence of a person with a human sensor using a pyroelectric element among infrared sensors is known.

  When such a room is larger than a certain size, when the room is divided into several areas, it is normal that areas where people are present and areas where people are not present are mixed. For this reason, a technology is known that realizes energy saving by detecting the presence or absence of a human by a human sensor and turning off illumination for an area where no human is present (for example, see Patent Document 1). ).

  In this way, if the presence or absence of a person is detected for each area, it is possible to turn on the illumination in an area where there is a person so as not to hinder the work of the person, and to turn off the illumination in an area where no person exists. This provides a bright and comfortable space while maintaining energy savings.

  However, since the human sensor is a sensor that detects a person existing in a predetermined detection area, there is a problem that if there is a gap in the detection area, the person may not be detected even if there is a person in the area. For example, consider a case where a human sensor is installed in a fluorescent lamp type illumination device. The size of the detection area of one human sensor varies depending on the distance to the target (the longer the distance, the larger the area), but the height of the ceiling of the room varies depending on the room, so people installed in the fluorescent lamp type lighting device The detection area of the sensation sensor becomes narrower when the ceiling is low.

  In general, fluorescent lamp illumination devices are installed at fixed intervals on the ceiling, but this interval varies depending on the room, and when the interval is long, between human sensors installed in the fluorescent lamp illumination device. The interval also becomes longer. For these reasons, a gap may occur in the detection area depending on the height of the ceiling and the interval between the fluorescent lamp type illumination devices.

  In view of the above-described problems, an object of the present invention is to provide a straight tube type LED illumination lamp in which an area where a target cannot be detected is unlikely to occur.

  In view of the above problems, the present invention provides a temperature distribution detecting means for detecting a temperature distribution of a space provided in one or both of the caps provided at both ends of the irradiation unit, and a temperature detected by the temperature distribution detecting means. Transmitting means for transmitting distribution data to an external control device, wherein the temperature distribution detecting means has directivity in at least two directions and has directivity changing means for changing the directivity. A tube-type LED illumination lamp is provided.

  It is possible to provide a straight tube type LED illumination lamp in which an area where the target cannot be detected is unlikely to occur.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

<Outline of lighting apparatus of this embodiment>
First, a detection area of a sensor for detecting a person will be described with reference to FIG. The detection area is a range where a person is detected when a detection target such as a person exists. FIG. 1 is an example of a diagram illustrating the orientation of the sensor and the gap generated in the detection area 501. This sensor is a temperature distribution sensor 311 described later. The temperature distribution sensor 311 is mounted on the detection device 3, and the detection device 3 is mounted on an illumination device (more specifically, a straight tube type LED illumination lamp). This lighting device is referred to as a first control target device 1.

  In FIG. 1, nine first control target devices 1 are installed in a lattice shape parallel to the longitudinal direction of the ceiling β. In FIG. 1, temperature distribution sensors 311 are attached to all the first control target devices 1.

  FIG. 1A shows the detection area 501 when the temperature distribution sensor 311 is installed so that the detection area 501 is widely formed in a direction perpendicular to the longitudinal direction of the first control target device 1. As is apparent from the figure, the detection area 501 overlaps perpendicularly to the longitudinal direction of the first control target device 1, and conversely, a gap 510 of the detection area 501 is generated in the longitudinal direction of the first control target device 1. .

  FIG. 1B shows the detection area 501 when the temperature distribution sensor 311 is installed so that the detection area 501 is widely formed in a direction parallel to the longitudinal direction of the first control target device 1. As apparent from the figure, since the detection areas 501 in the longitudinal direction of the first control target device 1 are largely overlapped, a gap 510 of the detection area 501 is generated in the direction perpendicular to the longitudinal direction of the first control target device 1. End up.

  FIG. 1C shows the detection area 501 when the temperature distribution sensor 311 is installed so that the detection area 501 is widely formed in an oblique direction with respect to the longitudinal direction of the first control target device 1. As is apparent from the figure, there is no gap between the detection areas.

  Therefore, even if the shape and size of the detection area 501 are the same, the gap can be eliminated or minimized depending on the direction of the detection area 501. For example, if the direction of the detection area 501 is determined by the direction in which the temperature distribution sensor 311 is installed, the temperature distribution sensor 311 depends on the direction (rotation angle) in which the temperature distribution sensor 311 is installed with respect to the first control target device 1. Even if the number of the same is the same, the gap in the detection area 501 can be eliminated or minimized.

  However, the interval between the first control target devices 1 varies depending on the room, and the size of the detection area 501 changes depending on the height of the ceiling. This means that the rotation angle of the temperature distribution sensor 311 where the gap is minimized differs depending on the room. It is not realistic to manufacture the first control target device 1 in which the temperature distribution sensor 311 is installed at a rotation angle that minimizes the gap between the detection areas 501 with respect to the living room, because this increases costs.

  Therefore, in the present embodiment, the first rotation mechanism that is installed in the first control target device 1 (which can of course be removed) can be rotated in parallel with the first control target device 1 is mounted. The control target device 1 will be described. If the rotation angle at which the gap disappears as shown in FIG. 1C is known, the administrator or the like can rotate the temperature distribution sensor 311, and the temperature distribution sensor 311 can be installed at a rotation angle at which the gap is minimized in any room. .

  FIG. 2 is an example of a diagram illustrating an outline of a rotation mechanism of a sensor mounted on the lighting device. The first control target device 1 is equipped with a detection device 3 having various sensors including a temperature distribution sensor 311. As an example, the detection device 3 includes two temperature distribution sensors 311, one illuminance sensor 312, and one temperature / humidity sensor 313. The number and type of these sensors are only examples. In addition, the detection device 3 includes an LED light emitting unit 318 that periodically emits light in order to notify people of life and death.

  Among these, the two temperature distribution sensors 311 are mounted on the sensor module MD. The sensor module MD rotates horizontally with respect to the first control target device 1 without changing the relative positions of the two temperature distribution sensors 311.

  FIG. 2A is a diagram illustrating an example of the temperature distribution sensor 311 in a state where the rotation angle of the sensor module MD is zero. Two temperature distribution sensors 311 are installed in a state in which the position in the longitudinal direction of the first control target device 1 is shifted. This is only because the storage in the first control target device 1 which is a fluorescent lamp is considered, and the longitudinal positions of the two temperature distribution sensors 311 may be the same. The detection area 501 in which the rotation angle is zero corresponds to the detection area 501 in FIG.

  FIG. 2B is a diagram illustrating an example of the temperature distribution sensor 311 in which the rotation angle of the sensor module MD is between 0 ° and 90 °. The sensor module MD is rotated by about 45 ° with respect to FIG. In FIG. 2B, the sensor module MD is installed on the inner side of the first control target device 1 than the illuminance sensor 312 and the temperature / humidity sensor 313. This is for explaining an arrangement example of the sensor module MD. is there. That is, the sensor module MD may be at the end of the LED lamp 130 (irradiation unit irradiated with light) or may be slightly inside the end. Moreover, you may exist in both or one side of the edge part of the 1st control object apparatus 1. FIG. Moreover, it may exist in a center part and should just be arrange | positioned and entered into a part of LED lamp 130. FIG.

  FIG. 2C is a diagram illustrating an example of the temperature distribution sensor 311 in which the rotation angle of the sensor module MD is about 90 °. The 90 ° sensor module MD is rotated with respect to FIG. The detection area 501 in a state where the rotation angle is 90 ° corresponds to the detection area 501 in FIG. The detection area 501 formed by the first control target device 1 having the two temperature distribution sensors 311 has a symmetrical shape, and the adjacent first control target device 1 also has the same detection area 501, so that the sensor module MD By rotating 0 to 90 °, it is possible to cover from a state where the gap of the detection area 501 is minimized to a state where it is maximized.

<Terminology>
Changing the directivity means changing the direction of an object having directivity. For example, when the detection direction of the temperature distribution sensor 311 has directivity, the detection direction of the temperature distribution sensor 311 is changed. Changing the direction of the detection area 501 naturally changes the directivity and the detection direction. Further, the change in the direction of the detection area 501 means that the directions of the two axes orthogonal to each other through the center of gravity of the detection area 501 change. The detection area 501 has a long axis and a short axis, and changing the direction of the detection area 501 means changing the directions of the two axes. One means for changing the directivity is rotation of the sensor module MD.

  When the sensor module MD rotates, a part of the detection device 3 rotates, the temperature distribution sensor 311 rotates, and the thermopile sensor rotates. In the following, these are not particularly distinguished. Moreover, rotating can be expressed as follows. Rotating around the axis of the light irradiated by the lighting device, rotating around the irradiation direction of the light irradiated by the lighting device, rotating around the center of the irradiation direction of the light irradiated by the lighting device, lighting Rotating around any direction in the light irradiation range irradiated by the device, the temperature distribution sensor 311 rotating horizontally relative to the ceiling, the temperature distribution sensor 311 rotating horizontally relative to the lighting device, or a sensor The temperature distribution sensor 311 rotates horizontally with respect to the module MD.

<Outline of device control system>
FIG. 3 is an example of a schematic configuration diagram of the device control system 100 according to the present embodiment. The device control system 100 includes a plurality of first control target 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, 2 The control target device 2, the wireless router 6, the administrator PC 7 (Personal Computer), and the management system 8 have a configuration capable of communicating via a network. Hereinafter, among the first control target devices (1 a, 1 b, 1 c, 1 d, 1 e, 1 f, 1 g, 1 h, 1 i), when referring to any first control target device, “first control target device 1 ".

  As shown in FIG. 3, the first control target device 1 is installed in each region 9 in which the ceiling β is divided into nine. And the detection apparatus 3 is provided in the 1st control object apparatus 1e installed in the center of the ceiling (beta). 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 first control target 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 first control target devices 1 are the same as in the case of a square.

  The second control target device 2 is installed at an appropriate interval on the ceiling β. In FIG. 3, there is one second control target device 2, but a plurality of second control target devices 2 are installed in one room α as will be described later. The second control target devices 2 are preferably installed at equal intervals, but may not be equal intervals. The number of the first control target device 1 and the second control target device 2 is different because the range that can be covered by the first control target device and the second control target device 2 is different, the size is different, the cost is different, etc. For the reason, the numbers of the first control target device and the second control target device 2 can be arbitrarily determined. In addition, when there are a plurality of second control target devices 2, the second control target device 2 is denoted by 2 a, 2 b, 2 c, respectively, and when indicating an arbitrary second control target device, “second control target device 2”. It describes.

  The 1st control object device 1 of this embodiment is an illuminating device as a fluorescent lamp type LED (Light Emitting Diode). The detection device 3 of the first control target device 1e detects, for example, a temperature distribution in which the room α is divided into a plurality of regions (here, 9 regions) by the function of a thermopile, and heat source data indicating the presence or absence of a heat source Is transmitted to the management system 8. 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 second control target device 2 of the present embodiment is an air conditioner such as an air conditioner (the indoor unit is shown in FIG. 3). The outdoor unit is installed in a predetermined place for each second control target device 2 or in common to the plurality of second control target devices 2. In addition, although the 2nd control object apparatus 2 and the management system 8 are connected with the wire in FIG. 3, you may communicate by radio | wireless.

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

  The management system 8 has a function of an information processing device as will be described later, and is sometimes called a server. The management system 8 generates control data for controlling the first control target device 1 and the second control target device 2 based on the heat source data sent from the wireless router 6, and the first control target device The first and second control target devices 2 are transmitted. The 1st control object apparatus 1 performs dimming control of LED based on control data. The second control target device 2 controls temperature, humidity, wind power, and wind direction based on the control data. Accordingly, the management system 8 can control both lighting and air conditioning to provide a space in which comfort and energy saving are taken into consideration for the people in the room.

  As is apparent from the above description, the first control target 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 its own device. The first control target device 1 e includes the detection device 3, but has the same function as the other first control target devices 1.

  Further, the detection device 3 may be installed inside or near the second control target device 2. Moreover, the 1st control object apparatus 1 or the 2nd control object apparatus 2 may be installed separately. However, since the detection device 3 is integrated with the first control target device 1, there is an advantage that the detection device 3 can be easily attached and detached, and there is no need to prepare a space for attaching the detection device 3.

  The administrator PC 7 is a PC operated by the administrator of the device control system 100. The administrator PC 7 communicates with the management system 8 and monitors various information detected by the detection device 3. Note that the administrator may be referred to as an administrator of the device control system 100, a user, or the like.

<Outline of first control target device>
Next, the apparatus main body 120 to which the first control target apparatus 1 and the first control target apparatus 1a are attached will be described with reference to FIG. FIG. 4 is an example of an external perspective view when the first control target device is a fluorescent lamp type LED lighting apparatus. In addition, the apparatus main body 120 may be called a lamp.

  As shown in FIG. 4, the first control target device 1 as a fluorescent lamp type LED lighting fixture has a straight tube type LED lamp 130 and is installed around the center of the ceiling β of the room α. It is attached to the apparatus main body 120. A socket 121a and a socket 121b are provided at both ends of the apparatus main body 120, respectively. 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. In the case of the first control target device 1 e, the detection device 3 is provided along the translucent cover 131, adjacent thereto, or inside the translucent cover 131. 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.

  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.

The communication method 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 surface temperature of a person or an object can be detected by using a thermal detection element, the temperature in a place close to a person can be detected. 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.

Further, the signal detected by each sensor is converted into a format that can be used by the device controller 315 and sent to the device controller 315.

  The device controller 315 is a control device that controls the entire detection device 3. The device controller 315 is an information processing device such as a microcomputer that has a CPU, a ROM, a RAM, and the like and executes a program. Alternatively, it 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 system 8.

  FIG. 5B is an example of a hardware configuration diagram of the first control target device 1 or the second control target device 2 according to the present embodiment. The device controller 315 of the first control target device 1 controls the dimming of the LED based on the control data transmitted from the management system 8. The device controller 315 of the second control target device 2 controls the air conditioner based on the control data transmitted from the management system 8.

  The device controller 315, the antenna I / F 302, and the wireless module 301 are the same as those in FIG. The first control target device 1 or the second control target device 2 includes a control target device 319. The control target device 319 is an LED lamp 130 or a control circuit for the LED lamp 130 in the case of the first control target device 1, and is a heat pump, a compressor and a control circuit for an air conditioner in the case of the second control target device 2. .

  In the case of the first control target device 1e having the detection device 3, the device controller 315, the antenna I / F 302, and the wireless module 301 may be common to the detection device 3. Thereby, the number of parts of the detection apparatus 3 can be reduced.

The transmission / reception unit 51 transmits / receives various data to / from the management system 8 via the communication network N.

  The control unit 55 is a function or means realized by the operation of the device controller 315. The control unit 35 generates a control signal to be output to the control target unit 20 based on the control data sent from the management system 8.

  In the case of the 1st control object device 1, control object part 20 is realized by LED lamp 130 etc. which are the objects of light control. In the case of the second control target device 2, the control target unit 20 is realized by a heat pump or a compressor of an air conditioner.

<Functional configuration of management system 8>
Next, the functional configuration of the management system 8 will be described. The management system 8 includes a transmission / reception unit 81, a collation unit 82, a generation unit 84, and a storage / read processing unit 89. Each unit is a function or means realized by operating according to a command from the CPU 801 in accordance with a management program expanded from the HD 804 and the RAM 803 shown in FIG. Furthermore, the management system 8 has a storage unit 8000 constructed by the RAM 803 and the HD 804 shown in FIG. In the storage unit 8000, a layout management DB (Data Base) 8001, a control guideline management DB 8002, and a control area management DB 8003 are constructed. First, these databases will be described.

(Layout management DB)
The layout management DB 8001 will be described with reference to FIG. The layout management DB 8001 manages the layout information of the first control target device 1 or the second control target device 2 as shown in FIG.

  As shown in FIG. 8A, the layout information includes one room α divided into 54 areas as an example, and each area 9 identifies the first control target device 1 as an LED lighting device. 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. 8A, the alphabetic x and the two-digit numerical value are the device ID of the second control target device 2. Although the 2nd control object apparatus 2 with apparatus ID x12, x21, x22 is not shown by FIG. 3, as shown to Fig.8 (a), it is installed in the ceiling (beta). That is, four air conditioners are attached to the ceiling β of the living room α.

  The ID is a name, code, character string, numerical value, or a combination thereof used to uniquely distinguish a specific target from a plurality of targets. The ID may be called identification information or an identifier. Specifically, a combination of serial numbers that does not overlap with the room number, a simple serial number, a serial number of the apparatus, and the like are not limited thereto.

  In the present embodiment, the device ID is used as identification information for identifying the region 9 by utilizing the fact that one first control target device 1 is installed in one region 9.

  FIG. 8B is a conceptual diagram of the layout information of the room α. Each area 9 of the layout information shown in FIG. 8A shows an area 9 separated by a wavy line or a solid line on the layout of the actual room α shown in FIG. 8B. Yes. FIG. 8B shows an actual layout in which desks and chairs are arranged. In FIG. 8B as well, the room is divided into 54 areas in the same manner as the room α in FIG. That is, the position of each area 9 in FIG. 8B is the same as the position of each area 9 in FIG. In FIG. 8B, the lower side of the paper is the corridor γ side, and the upper side of the paper is the window side.

(Control guideline management DB)
Next, the control guideline management DB 8002 will be described with reference to FIG. A first control guideline management table as shown in FIG. 9A is managed in the control guideline management DB. 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% and the heat source field. 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.

  In addition, a control guideline management table may be set for each first control target device 1 and each region 9. As a result, the management system 8 can control the first control target device 1 with control guidelines that differ depending on the first control target device 1.

  The control guide management DB 8002 manages a second control guide management table as shown in FIG. 9B. 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 a difference between the target value when the second control target device 2 controls the temperature and the temperature detected by the temperature distribution sensor 311. According to the second control guideline management table of FIG. 9B, 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 second control target device 2 is controlled so that the temperature becomes + 2 ° C. with respect to the target value. If the humidity is H1% or higher even with the same human density (1 to 19%) and the same temperature range, the second controlled device 2 is controlled dry.

  Control guidelines for air conditioning as shown in FIG. 9B are set for each human density according to the combination of temperature gap and humidity. Therefore, the management system 8 can finely control the air conditioning. For example, when the human density is high, the management system 8 controls the second control target device 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. it can. 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. The human density is calculated based on how many regions 9 among the plurality of regions in the control range of the second control target device 2 are known.

(Control area management DB)
Next, the control area management DB 8003 will be described with reference to FIG. A control area management table as shown in FIG. 10 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 second control target apparatus 2. The area ID is the device ID of the first control target device 1. As can be seen from FIG. 8A, the device ID of the second control target device 2 is associated with the region ID of the 3 × 3 region 9 centering on the second control target device 2.

  Note that 3 × 3 is merely an example and may be 4 × 4 or the like, and the second control target device closest to each region 9 may be associated with the region 9. With respect to the first control target device 1, since one region 9 is associated with one first control target device 1, a control region management table is unnecessary, but one first control target device 1 is the first. When the control is performed using the presence or absence of the heat source in the region 9 that is not limited to just below the control target apparatus 1, a control region management table as shown in FIG. 10 is prepared.

(Functional configuration of the management system)
Next, returning to FIG. 7, each functional configuration of the management system 8 will be described. The transmission / reception unit 81 illustrated in FIG. 7 receives, for example, detection data from the detection device 3 or transmits control data to the detection device 3.

  The collation unit 82 collates, for example, the layout information shown in FIG. 8A and heat source data shown in FIG. Thereby, the presence or absence of a person for each area 9 is determined.

  The generation unit 84 refers to the verification result of the verification unit 82 and the first control guide management table, and generates control data indicating the amount of light for the first control target device 1. Further, the generation unit 84 refers to the collation result of the collation 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, the air conditioner for the second control target device 2. Control data is generated.

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

<Operation procedure>
Hereinafter, the processing or operation of the management system 8 will be described with reference to FIGS. FIG. 11 is an example of a sequence diagram showing processing of the management system 8. FIG. 12A is a conceptual diagram of the temperature distribution detected by the temperature distribution sensor 311, and FIG. 12B is an example of a conceptual diagram of heat source data indicating the presence or absence of a heat source. FIG. 13 is a conceptual diagram of heat source data indicating the presence / absence of heat sources in all regions 9 in the room α.

  Here, the management system 8 generates control data for controlling the first control target device 1e based on various data detected by the first control target device 1e, and the first control target device 1, and Processing in which the first control target device 1 and the second control target device 2 perform light control and air conditioning by transmitting control data to the second control target device 2 is described. For simplification of description, among the plurality of first control target devices 1, the first control target device 1 e provided with the detection device 3, the other first control target device 1, and the second control target device 2. The process will be described.

  S21: First, the detection unit 32 of the first control target device 1e detects the temperature distribution of each region 9 in the living room α.

  S22: Next, the determination unit 33 determines whether or not the temperature is within a predetermined range value (for example, 30 ° C. to 35 ° C.) for each region, so that the generation unit 34 performs heat source data based on the determination result. Is generated.

  Here, generation of heat source data will be described with reference to FIG. 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. 12 (a) and FIG. 12 (b), 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 above 36 ° C. is represented as “0”.

  S23: Returning to FIG. The detection unit 32 of the first control target device 1e detects illuminance, temperature, and humidity in the vicinity of the first control target device 1e.

  S24: The transmission / reception unit 31 of the first control target apparatus 1e transmits the detection data to the management system 8. 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 system 8 receives detection data.

  FIG. 13 shows heat source data obtained by combining heat source data transmitted from a plurality of first control target devices 1 having the detection device 3. FIG. 13 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. 12B corresponds to the heat source data of the upper left block B in FIG.

  S25: Next, the storage / reading processing unit 89 of the management system 8 reads the layout information shown in FIG. 8A from the layout management DB 8001.

  S26: The collation unit 82 collates the layout information shown in FIG. 8A and the heat source data shown in FIG. By this collation, for example, in the area 9 where the first control target 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”.

  S27-1: Next, the storage / reading processing unit 89 of the management system 8 uses “1” and “0” indicating the presence or absence of the heat source in the heat source data as a search key, and the first control guide management table of the control guide management DB 8002 To retrieve the corresponding light quantity.

  S27-2: The storage / reading processing unit 89 of the management system 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.

  S28: And the production | generation part 84 produces | generates the control data which show the light quantity with respect to the 1st control object apparatus 1. FIG. In addition, the generation unit 84 generates control data for the second control target device 2. Thus, based on one detection data transmitted in step S24 (based on the same detection data), both control data for the first control target device 1 and control data for the second control target device 2 can be created. Therefore, even when the two devices of the first control target device 1 and the second control target device 2 are controlled, the number of times that the detection device 3 detects or the management system 8 receives the detection data can be reduced by half. . Moreover, since the same detection data is used, it becomes easy to take consistency of operation | movement of the 1st control object apparatus 1 and the 2nd control object apparatus 2. FIG.

  S29-1, S29-2: Next, the transmitting / receiving unit 51 transmits the respective control data to the first control target device 1. On the other hand, the transmission / reception unit 31 of the first control target device 1e receives control data. In addition, the transmission / reception unit 51 of the first control target device 1 other than the first control target device 1e receives the control data.

  S30-1, S30-2: Next, in the first control target device 1e, the control unit 35 generates a control signal to be output to the control target unit 20 as an LED lamp based on the control data. Similarly, the control part 55 of 1st control object apparatuses 1 other than the 1st control object apparatus 1e produces | generates the control signal for outputting to the control object part 20 as an LED lamp based on control data.

  S31-1, S31-2: The control unit 35 outputs a control signal to the control target unit 20. The control unit 55 outputs a control signal to the control target unit 20.

  S32-1, S32-3: Thereby, the light quantity of the control target unit 20 as the LED lamp is controlled.

  S33: The transmission / reception unit 81 of the management system 8 transmits control data to the second control target device 2. On the other hand, the transmission / reception part 51 of the 2nd control object apparatus 2 receives control data.

  S34: The control part 55 of the 2nd control object apparatus 2 produces | generates the control signal for outputting to the control object part 20 as an air conditioner based on control data. Thereby, the temperature, humidity, air volume, and wind direction of the control target unit 20 as an air conditioner are controlled.

  For example, in FIG. 12, 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 first control target device 1 in the area 9 whose ID is a22 is controlled to 60%. On the other hand, in FIG. 12, since there is a heat source directly below the area 9 with the area ID a21 (indicated by “1”), the area ID is a21 according to the first control guide management table of FIG. The amount of light of the first control target device 1 in the region 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.

<Judgment of presence or absence of heat source>
A method for determining the presence or absence of the heat source described in step S22 of FIG. 11 will be described.
FIG. 14 is an example of a flowchart illustrating a heat source data generation method. FIG. 15A is a conceptual diagram showing a temperature distribution, and FIG. 15B 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 system 8 extracts the region 9 in 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 S101). .

  Then, the determination unit 33 determines whether or not the temperature of the region 9 extracted in step S101 is within a predetermined range (step S102). For example, when an electric pot (water heater) is installed in the region 9 where the first control target device 1 with the device ID a13 is installed, as shown in FIG. The temperature of the region 9 may reach 60 ° C. due to the heat of the container. 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 it is determined in step S102 that it is within the predetermined range (YES), the determination unit 33 determines that there is a heat source (step S103). In this case, as shown in FIG. 15B, “1” indicating that there is a heat source is set in the heat source data.

  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 S104). In this case, as shown in FIG. 15B, “0” indicating that there is no heat source is set in the heat source data.

  Then, after the processing of steps S103 and 104, the determination unit 33 determines whether or not the determination on whether or not the temperature is within the predetermined range has been completed in all the regions 9 (step S105). If it is determined in step S105 that all the regions 9 have been determined (YES), the processing in step S22 in FIG. 11 ends. On the other hand, if it is determined in step S105 that the determination of all the regions 9 has not been completed (NO), the process returns to step S101.

  In this way, according to the process shown in FIG. 14, even if a heat source exists, if it exceeds the range of the heat source by a specific object (for example, a human), the heat source is not handled. , More accurately detect human presence. Thereby, there exists an effect that an energy saving can be implement | achieved more correctly.

<About the shape of the detection area>
In FIG. 1, two temperature distribution sensors 311 are installed in one LED lamp 130. This is due to the following reasons. 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 tends to increase due to construction or maintenance. Therefore, it is considered to install a plurality of temperature distribution sensors 311 in one first control target device 1 (LED lamp 130). 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. This is because a plurality of temperature distribution sensors 311 are installed in a limited place that is integrated with or in the vicinity of the first control target device 1. Therefore, if no inclination is provided, the temperature of one temperature distribution sensor 311 is detected. This is because the area 501 cannot be expanded.

  FIG. 16 is an example of a diagram illustrating the relationship between the number of temperature distribution sensors 311 and the detection area 501. In FIG. 16A, since the temperature distribution sensor 311 is one and is installed perpendicular to the ceiling (floor surface), the detection area 501 is a square (or a rectangle). In FIG. 16B, there are two temperature distribution sensors 311, but each detection area 501 is distorted due to trapezoidal distortion because it is installed with a δ inclination on the ceiling (floor surface). Shape (trapezoid). In FIG. 16 (c), there are four temperature distribution sensors 311. However, since the temperature distribution sensors 311 are installed with a slope of δ with respect to the ceiling (floor surface), each detection area 501 is one diagonal line of a square. It becomes a distorted shape (a shape close to a rhombus) that is only extended. This is because the temperature distribution sensor 311 is installed in a state rotated by 90 ° with respect to FIG.

  The shape of the detection area 501 in FIG. 1 is the shape in the case where there are two temperature distribution sensors 311 as shown in FIG. Four temperature distribution sensors 311 may be mounted on one first control target device 1. The number of temperature distribution sensors 311 may be three, and the number is arbitrary.

  In FIG. 16, one detection area 501 is divided into a plurality of detection masses 502, which indicates a range in which one thermopile of the temperature distribution sensor 311 detects temperature. In FIG. 16, since one temperature distribution sensor 311 has, for example, a 4 × 4 thermopile sensor, one detection area 501 is divided into 16 detection masses 502. There is no gap between the detection mass 502 and the detection mass 502, or even if there is a gap, there is no problem in detecting a person.

  The direction connecting the center of the detection area 501 and the temperature distribution sensor 311 or the center of the detection mass 502 and the thermopile sensor is the detection direction of the temperature distribution sensor 311 or the thermopile sensor. It can be seen that the detection direction changes when the temperature distribution sensor 311 rotates with respect to the ceiling, for example.

  FIG. 17 is an example of a diagram illustrating the direction of the detection area 501. The two detection areas 501 have a major axis “a” and a minor axis “b” orthogonal to each other through the center of gravity O. The reason that the gap changes depending on the direction of the detection area 501 is that the length of the axis that goes straight through the center of gravity O is different. As shown in FIGS. 17A and 17B, when the temperature distribution sensor 311 rotates with respect to the ceiling, for example, the detection direction of the temperature distribution sensor 311 changes and the shape and size of the detection area 501 remain substantially constant, while the center of gravity is maintained. The detection area 501 rotates around O. Also, the orientation of the major axis a and the minor axis b changes.

<About irradiation direction>
FIG. 18 is an example of a diagram illustrating the irradiation direction of the LED lamp 130. As shown in FIG. 18A, if the LED lamp 130 is installed in the apparatus main body 120 and the direction directly below the LED lamp 130 is defined as the irradiation direction P, the temperature distribution sensor 311 has the irradiation direction P as the axis. Rotate to.

  Further, as shown in FIG. 18B, if the irradiation direction is a range m in which the light from the LED lamp 130 spreads, the temperature distribution sensor 311 can irradiate the irradiation direction of the light irradiated by the illumination device (any of the infinite number of light rays). Rotate around the center. Further, it can be said that the LED lamp 130 rotates around an arbitrary direction within the light irradiation range.

  18 (a) and 18 (b), it can be said that the temperature distribution sensor 311 rotates horizontally with respect to the ceiling, rotates horizontally with respect to the first control target device 1, and rotates horizontally with respect to the installation surface.

  As shown in FIG. 18C, when the apparatus main body 120 includes the reflector 610, the central direction of the irradiation direction is not perpendicular to the ceiling. However, the temperature distribution sensor 311 is the same in that it rotates around the irradiation direction P and rotates around the irradiation direction (any one of innumerable rays) of light irradiated by the illumination device. Although it cannot be said that the temperature distribution sensor 311 rotates horizontally with respect to the ceiling, it can be said that the temperature distribution sensor 311 rotates horizontally with respect to the first control target device 1 and rotates horizontally with respect to the installation surface (reflector 610).

<Structure of detection device>
Hereinafter, the structure of the detection device 3 and the like will be described with reference to FIGS. FIG. 19 shows an exploded view of the detection device 3. As described above, the two temperature distribution sensors 311 are housed inside the thermopile cover 401. The thermopile cover 401 has two openings 401 a that are opened at least as large as the temperature distribution sensor 311 in the detection direction of the temperature distribution sensor 311. The opening on the far side of the paper surface is hidden behind the thermopile cover 401. As shown in FIG. 16B, the temperature distribution sensors 311 are arranged with inclinations in opposite directions with respect to the ceiling. Further, the positions of the two temperature distribution sensors 311 are different with respect to the longitudinal direction (axial direction) of the first control target device 1 because the size of the thermopile cover 401 is smaller than the size of the temperature distribution sensor 311. The positions in the longitudinal direction of the two temperature distribution sensors 311 may be the same. However, the difference in the degree shown in the figure does not hinder the detection of a person.

  The two temperature distribution sensors 311 have a storage plate 408 (described later) that rotatably supports the thermopile cover 401 on the back side thereof. The thermopile cover 401 and the storage plate 408 form a storage unit that stores the two temperature distribution sensors 311. The storage plate 408 holds the thermopile cover 401 while rotating horizontally with respect to the holder cover portion 402. Details will be described with reference to FIG.

  The holder cover part 402 has a circular opening 402a through which a wiring used for communication such as a detection signal of the temperature distribution sensor 311 passes while pivotally supporting the storage plate 408. In addition, the holder cover portion 402 has an opening 402b at the end near the LED light emitting tube portion 407, through which light from the LED light emitting portion 318 passes and the temperature / humidity sensor portion 317 detects temperature and humidity.

  Thus, the thermopile cover 401 and the storage plate 408 storing the two temperature distribution sensors 311 are rotatably attached to the holder cover part 402 and attached to the aluminum structure part 403. An LED light emitting unit 318 and a temperature / humidity sensor unit 317 are disposed at the end of the aluminum structure unit 403 near the LED light emitting tube unit 407. The holder cover unit 402 has a space corresponding to the height of the LED light emitting unit 318 and the temperature / humidity sensor unit 317. When the holder cover unit 402 is attached to the aluminum structure unit 403, the LED light emitting unit 318 and the temperature / humidity are placed in this space. The sensor unit 317 is accommodated. The aluminum structure 403 has an opening 403a through which a wiring used for communication such as a detection signal of the temperature distribution sensor 311 passes. In addition, the wiring used for communication, such as a detection signal of the LED light emission part 318 or the temperature / humidity sensor part 317, may pass.

  A wireless substrate 404 is fixed to the bottom surface of the aluminum structure 403 from below. The wireless board unit 404 is an electronic board on which the device controller 315, the antenna 302a, the antenna I / F 302, the wireless module 301, the sensor driver 304, and the like illustrated in FIG. Wiring used for communication of detection signals of the temperature distribution sensor 311 and wiring used for communication of detection signals of the LED light emitting unit 318 and the temperature / humidity sensor unit 317 are electrically connected to the wireless substrate unit 404. The

  The thermopile cover 401, the holder cover part 402, the aluminum structure part 403, and the wireless board part 404 are fixed to one by a screw, a coupling structure, or the like, and fit to the same size as the diameter of the LED arc tube part 407. These are housed in the base holder part 406, mounted on the LED light emitting tube part 407, and the end part in the longitudinal direction is closed by the base part 405. The base unit 405 is electrically connected to the wireless board unit 404, and power is supplied to the detection device 3 through the base.

  FIG. 20 is an example of a diagram illustrating the structure of the storage plate 408. FIG. 20A is an example of a plan view of the storage plate 408 as viewed from the holder cover portion 402. Since the temperature distribution sensor 311 is stored at the back side of the sheet, the storage plate 408 is provided with an opening 408a for wiring. A cylindrical fitting portion 408c is formed around the opening 408a. The cylinder fitting portion 408c is a cylinder formed on the front side of the sheet. The opening 408a is provided with snap fits 408b at two locations facing each other. The snap fit 408b is a kind of mechanical joining method used for joining metals, plastics, and the like, and refers to a joining method in which one part is fitted into the other part using the elasticity of the material. The snap fits 408b protrude from the storage plate 408 on the front side of the sheet.

  FIG. 20B shows an example of a cross-sectional view of the snap fit 408 b of the storage plate 408 and the holder cover portion 402. This sectional view is a sectional view taken along the line AA 'in FIG. When the storage plate 408 approaches and comes into contact with the holder cover portion 402, the claw portion 408d is urged radially inward by the edge of the opening 402a. Since the snap fit 408b is formed of an elastic material, the claw portion 408d is elastically deformed so as to pass through the inside of the opening 402a. When the return 408e of the claw 408d finishes passing through the opening 402a, the claw 408d is released from the urging force by the edge of the opening 402a and tries to return to its original shape. The barb 408e contacts the edge of the opening 402a and cannot get over the edge of the opening 402a. Further, due to the difference in diameter between the opening 402a and the cylindrical fitting portion 408c, the cylindrical fitting portion 408c biases the opening 402a outward in the radial direction. A rubber material 402c is affixed to almost the entire circumference of the edge of the opening 402a of the holder cover 402.

  FIG. 20C is a view showing a state in which the snap fit 408 b of the storage plate 408 is attached to the opening 402 a of the holder cover portion 402. The storage plate 408 is fixed to the holder cover portion 402 in principle by the urging force that the cylindrical fitting portion 408c urges the opening 402a radially outward and the frictional force of the rubber material 402c. When a rotating force is applied to overcome the force, the storage plate 408 rotates in an exceptionally pivoted state with respect to the holder cover portion 402. With such a structure, the sensor module MD can be rotated at an arbitrary rotation angle. The rubber material is not limited to rubber as long as it is a member having a high frictional force. Examples thereof include a resin and a material having fine irregularities on the surface.

  FIG. 21 is an example of a diagram illustrating the angle adjustment mechanism 402d with respect to the perspective view of the storage plate 408 and the holder cover portion 402. FIG. It should be noted that the arrangement of the storage plate 408 and the holder cover portion 402 is upside down from FIG. This is for explaining the angle adjustment mechanism 402d. The storage plate 408 has been described with reference to FIG. 21 has an angle adjusting mechanism 402d facing each other. The angle adjusting mechanism 402d is formed in an arc shape in the circumferential direction of the opening 402a.

  When the storage plate 408 is attached to the holder cover portion 402 via the snap fit 408b, the return 408e of the claw portion 408d of the snap fit 408b comes into contact with the opening 402a side of the angle adjustment mechanism 402d. The opening 402a side of the angle adjustment mechanism 402d has a continuous uneven portion 402e, and the angle adjustment mechanism 402d is stable in a state where the barb 408d has a barb 408e in contact with the recess.

  In order for the snap fit 408b to rotate in the circumferential direction of the opening 402a, the barbs 408d of the barbs 408d need to get over the convex portion. For this reason, the storage plate 408 is maintained in a stable state at a certain rotation angle. On the other hand, when a force is applied to rotate the snap fit 408b in the circumferential direction, the convex portion of the angle adjusting mechanism 402d comes into contact with the return 408e of the claw portion 408d, and the return 408e of the claw portion 408d is radially inward of the opening 402a. Be energized. Since the snap fit 408b is made of an elastic material, the snap fit 408b is elastically deformed radially inward, and the return 408e of the claw portion 408d is stabilized in a state of overcoming the convex portion of the angle adjusting mechanism 402d and in contact with the adjacent concave portion.

  Therefore, if the angle adjustment mechanism 402d is designed so that the repetition period of the concave portion and the convex portion (the length of one adjacent concave portion and one convex portion) is constant, the storage plate 408 (that is, the sensor module MD). Is rotated by a certain angle. Therefore, it is easy for an administrator or the like to position at a certain rotation angle.

  Further, if nine concave portions and convex portions are formed at an equal interval in a range of 90 °, for example, the administrator or the like can determine the rotation angle every 10 degrees. Therefore, the rotation angle can be determined by an absolute value having a resolution of 10 degrees.

  Stopper portions 402f are formed at both ends of the angle adjusting mechanism 402d. The stopper portion 402f defines the range of the rotation angle. The stopper portion 402f protrudes longer in the radial direction of the opening 402a than the convex portion. When a rotating force is applied to the storage plate 408 and the return 408e of the claw portion 408d reaches the stopper portion 402f, more force is required to get over the stopper portion 402f than to get over the convex portion. Therefore, it is possible to notify the administrator or the like that the storage plate 408 does not rotate any more due to the reaction force applied by the stopper portion 402f to the return 408e of the claw portion 408d. The range in which the rotation is not limited by the stopper portion 402f is, for example, 90 °, but is not limited to 90 °.

  By forming the stopper portion 402f, the sensor module MD can be prevented from rotating more than expected. For example, since the wiring passes through the opening 402a, the wiring can be prevented from being largely twisted.

<Modification>
For example, a notch may be used as a mechanism that allows the rotation angle of the sensor module MD to be changed.

  FIG. 22 is an example of a diagram illustrating a schematic structure of the storage plate 408 having a notch and the holder cover portion 402. FIG. 22A is an example of a plan view of the storage plate 408 viewed from the holder cover portion 402. Since the temperature distribution sensor 311 is stored at the back side of the sheet, the storage plate 408 is provided with an opening 408a for wiring. In addition, plate-like protrusions 408j are provided at two locations facing the opening 408a. Each of the plate-like protrusions 408j protrudes from the storage plate 408 on the front side of the sheet.

  FIG. 22B shows an example of a cross-sectional view of the plate-like protrusion 408j. This sectional view is a sectional view taken along the line BB 'in FIG. The plate-like protrusion 408j has a snap fit 408g on the outer side in the radial direction. The action of the snap fit 408g is the same as that in FIG.

  FIG. 22C is an example for explaining the opening 402 a of the holder cover portion 402. A plurality of notches 402 g are formed in the opening 402 a of the holder cover portion 402. The plate-like protrusion 408j in FIG. 22 (a) is inserted into the notch 402g and maintains the state of being attached by the barbs 408h of the claw portion 408h of the snap fit 408g at the end of the plate-like protrusion 408j. If the positions of the plate-like protrusion 408j and the notch 402g do not coincide with each other, the storage plate 408 is not attached to the holder cover portion 402, so that the rotation angle of the storage plate 408 can be determined where the notch 402g is. For example, if there are seven notches 402g at equal intervals in the range of 90 °, the rotation angle is determined every 15 °. Note that seven is an example, and the resolution may be higher or lower.
