[0010] Hereinafter, the embodiments will be described in detail with reference to the drawings. Note that the embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component arrangement and connection forms, steps, and order of steps shown in the following embodiments are merely examples and are not intended to limit the present invention. In addition, among the components in the following embodiments, components that are not described in the independent claims will be described as optional components.

[0011] In addition, each drawing is a schematic diagram and is not necessarily a precise illustration. In each drawing, the same reference numerals are used for substantially the same configurations, and duplicated explanations may be omitted or simplified.

[0012] (Embodiment) [composition] First, the configuration of a control system according to an embodiment will be described below. Fig. 1 is a block diagram showing the functional configuration of a control system according to an embodiment.

[0013] The control system 10 is a system capable of controlling devices installed in a large-scale facility (such as a building) consisting of several floors, and monitoring the devices. The facility is, for example, a building such as a commercial facility or an office, but is not limited thereto, and may be a non-residential facility such as a hospital or a factory. The facility may also be a detached house or an apartment building. The control system 10 includes a power supply unit 20, a control device 30, a communication IF unit 40a, a communication IF unit 40b, a communication IF unit 40c, an air conditioning system 50, one or more (hereinafter simply referred to as one or more) lighting devices 61a, one or more detection devices 62a, one or more lighting devices 61b, one or more detection devices 62b, and an air conditioning system 50c.

[0014] First, the power supply unit 20, the control device 30, the communication IF unit 40a, the communication IF unit 40b, and the communication IF unit 40c will be described. The power supply unit 20, the control device 30, the communication IF unit 40a, the communication IF unit 40b, and the communication IF unit 40c are separate devices, and each of the power supply unit 20, the control device 30, the communication IF unit 40a, the communication IF unit 40b, and the communication IF unit 40c is realized by incorporating a circuit board or the like in a housing. Figure 2 is an external view of the power supply unit 20, the control device 30, the communication IF unit 40a, the communication IF unit 40b, and the communication IF unit 40c.

[0015] 2, the power supply unit 20, the control device 30, the communication IF unit 40a, the communication IF unit 40b, and the communication IF unit 40c are attached to a mounting member such as a rail 80. Note that the control system 10 does not need to include all of the communication IF unit 40a, the communication IF unit 40b, and the communication IF unit 40c, and may include only the necessary units.

[0016] The power supply unit 20 is connected to each of the control device 30, the communication IF unit 40a, the communication IF unit 40b, and the communication IF unit 40c by power lines, and supplies power to each of the control device 30, the communication IF unit 40a, the communication IF unit 40b, and the communication IF unit 40c. The power supply unit 20 is realized by a power supply circuit that converts AC power to DC power, etc.

[0017] The control device 30 is connected to each of the communication IF unit 40a, the communication IF unit 40b, the communication IF unit 40c, the air conditioning controller 51, and the management terminal 70 via signal lines, and communicates with each of the communication IF unit 40a, the communication IF unit 40b, the communication IF unit 40c, the air conditioning controller 51, and the management terminal 70.

[0018] The control device 30 controls one or more air conditioners 52, one or more lighting devices 61a, one or more detectors 62a, one or more lighting devices 61b, one or more detectors 62b, and one or more air conditioners 52c. The control device 30 may control only a part of one or more air conditioners 52, one or more lighting devices 61a, one or more detectors 62a, one or more lighting devices 61b, one or more detectors 62b, and one or more air conditioners 52c. In other words, the control device 30 only needs to control at least a part of one or more air conditioners 52, one or more lighting devices 61a, one or more detectors 62a, one or more lighting devices 61b, one or more detectors 62b, and one or more air conditioners 52c.

[0019] The control device 30 also monitors one or more air conditioning devices 52, one or more lighting devices 61a, one or more detectors 62a, one or more lighting devices 61b, one or more detectors 62b, and one or more air conditioning devices 52c. The control device 30 may monitor only a part of one or more air conditioning devices 52, one or more lighting devices 61a, one or more detectors 62a, one or more lighting devices 61b, one or more detectors 62b, and one or more air conditioning devices 52c. In other words, the control device 30 only needs to monitor at least a part of one or more air conditioning devices 52, one or more lighting devices 61a, one or more detectors 62a, one or more lighting devices 61b, one or more detectors 62b, and one or more air conditioning devices 52c.

[0020] The functions of the control device 30 are realized by a microcomputer or processor (hardware) executing a computer program (software) stored in a memory.

[0021] The one or more air conditioners 52 are controlled based on communication between the control device 30 and the air conditioning controller 51, and the one or more lighting devices 61a and the one or more detectors 62a are controlled based on communication between the control device 30 and the communication IF unit 40a (controller 41a). The one or more lighting devices 61b and the one or more detectors 62b are controlled based on communication between the control device 30 and the communication IF unit 40b (controller 41b), and the one or more air conditioners 52c are controlled based on communication between the control device 30 and the communication IF unit 40c (air conditioning controller 51c).

[0022] The communication IF unit 40a is a communication module to which devices compatible with a first communication protocol (first communication standard) are connected. The first communication protocol is, for example, a protocol compatible with a two-wire multiplex transmission method. Devices compatible with the first communication protocol include a lighting device 61a and a detection device 62a. Such devices also include a switch for turning on or off the lighting device 61a, and a relay for turning on or off the power supply to the lighting device 61a by operating the switch.

[0023] The communication IF unit 40a includes a controller 41a, which performs at least one of controlling and monitoring devices connected to the communication IF unit 40a. Specifically, the controller 41a is realized by a microcomputer or a processor and a memory. The functions of the controller 41a are realized by the microcomputer or the processor (hardware) executing a computer program (software) stored in the memory.

[0024] For example, in order to control the lighting device 61a, it is generally necessary to connect a lighting controller to the communication IF unit 40a. However, in the control system 10, since the communication IF unit 40a is equipped with the controller 41a, it is not necessary to connect the lighting controller to the communication IF unit 40a.

[0025] The communication IF unit 40b is a communication module to which devices compatible with a second communication protocol (second communication standard) are connected. The second communication protocol is, for example, a protocol compatible with a two-wire multiplex transmission method and is different from the first communication protocol. Devices compatible with the second communication protocol include the lighting device 61b and the detection device 62b. Such devices also include a switch for turning on or off the lighting device 61b, and a relay for turning on or off the power supply to the lighting device 61b by operating the switch.

[0026] The communication IF unit 40b includes a controller 41b, which performs at least one of control and monitoring of devices connected to the communication IF unit 40b. Specifically, the controller 41b is realized by a microcomputer or a processor and a memory. The functions of the controller 41b are realized by the microcomputer or the processor (hardware) executing a computer program (software) stored in the memory.

[0027] For example, in order to control the lighting device 61b, it is generally necessary to connect a lighting controller to the communication IF unit 40b. However, in the control system 10, since the communication IF unit 40b is equipped with the controller 41b, there is no need to connect the lighting controller to the communication IF unit 40b.

[0028] The communication IF unit 40c is connected to devices compatible with RS232C or RS485. In the control system 10, the communication IF unit 40c is connected to an air conditioning controller 51c.

[0029] Next, the air conditioning system 50, the lighting device 61a, the detection device 62a, the lighting device 61b, the detection device 62b, the air conditioning system 50c, and the management terminal 70 will be described.

[0030] The air conditioning system 50 includes an air conditioning controller 51 connected to a communication IF (e.g., a communication IF compatible with a wired LAN) provided in the control device 30, and one or more air conditioning devices 52 controlled by the air conditioning controller 51. The communication protocol for communication between the air conditioning controller 51 and the control device 30 is, for example, BACnet (Building Automation and Control Networking protocol) based on a wired LAN.

[0031] Specifically, the air conditioning controller 51 is realized by a microcomputer or a processor and a memory. The functions of the air conditioning controller 51 are realized by the microcomputer or the processor (hardware) executing a computer program (software) stored in the memory.

[0032] The air conditioner 52 is a device that adjusts the temperature within the facility by blowing out temperature-adjusted air within the facility.

[0033] The lighting device 61a is connected to the communication IF unit 40a and brightly illuminates the space within the facility. The detection device 62a is a device that performs sensing to control the lighting device 61a, and detects the state of people or objects other than people in a detection target area, and outputs detection information as a detection result. The state of people includes at least one of the presence or absence of people, the number of people, the amount of activity of people, and people's behavior. The detection device 62a can also detect the illuminance in the detection area and output detection information as a detection result.

[0034] The controller 41a of the communication IF unit 40a, one or more lighting devices 61a, and one or more detection devices 62a configure a lighting system 60a.

[0035] The lighting device 61b is connected to the communication IF unit 40b and brightly illuminates the space within the facility. The detection device 62b is a device that performs sensing to control the lighting device 61b, detects the state of people or objects other than people in the detection target area, and outputs detection information as the detection result. The detection device 62b can also detect the illuminance in the detection area and output the detection information as the detection result.

[0036] The controller 41b of the communication IF unit 40b, one or more lighting devices 61b, and one or more detection devices 62b configure a lighting system 60b.

[0037] The air conditioning system 50c includes an air conditioning controller 51c connected to the communication IF unit 40c, and one or more air conditioners 52c controlled by the air conditioning controller 51c.

[0038] Specifically, the air conditioning controller 51c is realized by a microcomputer or a processor and a memory. The functions of the air conditioning controller 51c are realized by the microcomputer or the processor (hardware) executing a computer program (software) stored in the memory.

[0039] The air conditioner 52c is a device that adjusts the temperature within the facility by blowing out temperature-adjusted air within the facility.

[0040] The management terminal 70 is installed in a central control room of the facility, and is a user interface device operated by a user to control and monitor the equipment installed in the facility. The management terminal 70 is realized by, for example, a personal computer. The management terminal 70 is connected to a communication IF (for example, a communication IF corresponding to a wired LAN) of the control device 30, and can communicate with the control device 30. The communication protocol (communication standard) in this case is, for example, BACnet based on the wired LAN.

[0041] The management terminal 70 may be provided outside the facility. In this case, a server device provided within the facility is connected to a communication IF (for example, a communication IF corresponding to a wired LAN) of the control device 30, and the management terminal 70 is connected to the server device via a wide area communication network such as the Internet.

[0042] [Detection device configuration] Next, the configuration of the detector 62a or 62b will be described. Fig. 3 is a diagram showing an installation example and an external appearance of the detector. In the following description, the detector 62a or 62b will also be referred to as the detector 62.

[0043] The detection device 62 is installed on a structure located on the ceiling side, such as a ceiling or beams, in the facility, and senses the presence or absence of people, the number of people, and the illuminance in the indoor space directly below the detection device 62. The detection device 62 includes an imaging unit 63, and can sense the presence or absence of people, the number of people, and the illuminance in the space by taking an image of the space and processing the taken image.

[0044] In addition, the detection device 62 can set multiple detection areas in the indoor space to be photographed (images captured by the imaging unit 63), and sense the presence or absence of people, the number of people, and the illuminance in each of the multiple detection areas.

[0045] According to such a detection device 62, the controller 41a can turn on the lighting device 61a provided in the detection area only when a person is present in the detection area, or dim the lighting device 61a provided in the detection area so that the illuminance of the detection area is substantially constant. Similarly, according to the detection device 62, the controller 41b can turn on the lighting device 61b provided in the detection area only when a person is present in the detection area, or dim the lighting device 61b provided in the detection area so that the illuminance of the detection area is substantially constant.

[0046] In the control system 10, the control device 30 is a higher-level controller than the controllers 41a and 41b, and can control devices equivalent to the controllers 41a, 41b, and the air conditioning controller 51c.

[0047] Furthermore, the control device 30 can also perform control to link two or more systems. For example, the control device 30 can acquire detection information output by the detection device 62 and provide the acquired detection information to the air conditioning controller 51. That is, the control system 10 can use the detection information of the detection device 62 used for lighting control purposes to control the air conditioning device 52. Similarly, the control device 30 can acquire detection information output by the detection device 62 and provide the acquired detection information to the air conditioning controller 51. That is, the control system 10 can use the detection information of the detection device 62 used for lighting control purposes to control the air conditioning device 52.

[0048] In this case, the control device 30 or the air conditioning controller 51 can operate the air conditioning equipment 52 installed in the detection area only when there is a person in the detection area, or can change the set temperature or wind speed of the air conditioning equipment 52 depending on an increase or decrease in the number of people in the detection area.

[0049] Similarly, the control device 30 can provide the air conditioning controller 51c with detection information of the detection device 62. In this case, the control device 30 or the air conditioning controller 51c can operate the air conditioning device 52c provided in the detection area only when there is a person in the detection area, or change the set temperature or air speed of the air conditioning device 52c according to an increase or decrease in the number of people in the detection area.

[0050] [Detection device setting system configuration] Various settings, including the settings of the above-mentioned multiple detection areas, can be made to the detection device 62. A setting system used for such various settings will be described below. Fig. 4 is a block diagram showing the functional configuration of the setting system.

[0051] 4, the setting system 90 includes a detection device 62, a repeater 91, and an information terminal 92. The detection device 62 includes an imaging unit 63, a plurality of thermal sensors 64, a first communication unit 65, a second communication unit 66, an information processing unit 67, and a storage unit 68.

[0052] The imaging unit 63 is a camera that captures images (videos). The imaging unit 63 is realized by an image sensor, an optical system for capturing images, etc. The imaging unit 63 captures an image of, for example, an area directly below the detection device 62 in the indoor space in which the detection device 62 is installed.

[0053] The thermal sensor 64 senses the presence or absence of a person around the detection device 62 by detecting infrared rays emitted from the human body. That is, the detection device 62 can determine the presence or absence of a person by performing image processing on the image captured by the imaging unit 63 and based on at least one of the sensing results of the thermal sensor 64. For example, when the surroundings of the detection device 62 are bright, the information processing unit 67 (human detection unit 67c) uses both the image and the sensing result to determine the presence or absence of a person, and when the surroundings of the detection device 62 are dark, the information processing unit 67 (human detection unit 67c) determines the presence or absence of a person based on the sensing result of the image and the sensing result. The detection device 62 includes four thermal sensors 64, and the four thermal sensors 64 are arranged at equal intervals so as to surround the imaging unit 63 in a plan view (shown in FIG. 3).

[0054] The first communication unit 65 communicates with the repeater 91 in a first wireless communication method using infrared rays. It can also be said that the first communication unit 65 communicates with the information terminal 92 via the repeater 91 in the first wireless communication method. The first communication unit 65 is realized by, for example, an infrared communication module (infrared communication circuit).

[0055] The second communication unit 66 communicates with the information terminal 92 in a second wireless communication method different from the first wireless communication method. More specifically, the second communication unit 66 communicates directly with the information terminal 92 in the second wireless communication method without going through the repeater 91. The second wireless communication method is a communication method using radio waves, and the second communication unit 66 is realized by, for example, a radio wave communication module (radio wave communication circuit). Note that the communication standard for radio wave communication is, for example, Bluetooth (registered trademark) Low Energy (BLE), but is not particularly limited.

[0056] The information processing unit 67 performs various information processing such as processing (image processing) of the image captured by the imaging unit 63 and processing related to the setting of the detection device 62. The information processing unit 67 is realized by, for example, a microcomputer, but may also be realized by a processor or a dedicated circuit. The information processing unit 67 includes, as functional components, a setting unit 67a, a control unit 67b, a human detection unit 67c, and an illuminance detection unit 67d.

[0057] The setting unit 67a sets the setting items of the detection device 62 based on communication using the first communication unit 65 or the second communication unit 66 (receiving a setting command from the information terminal 92). The control unit 67b executes a special operation for inspection. The human detection unit 67c detects the presence or absence of a human in the detection area based on the image captured by the imaging unit 63 or the sensing result of the thermal sensor 64. The illuminance detection unit 67d detects the illuminance in the detection area based on the image captured by the imaging unit 63.

[0058] The functions of the setting unit 67a, the control unit 67b, the human detection unit 67c, and the illuminance detection unit 67d are realized by hardware such as a microcomputer or a processor that constitutes the information processing unit 67 executing a computer program (software) stored in the memory unit 68.

[0059] The storage unit 68 is a storage device that stores information necessary for the above information processing. The information stored in the storage unit 68 includes a computer program executed by the information processing unit 67. The storage unit 68 is realized by, for example, a semiconductor memory.

[0060] The repeater 91 communicates with the detection device 62 using a first wireless communication method (infrared) and communicates with the information terminal 92 using a second wireless communication method (radio waves). In other words, the repeater 91 converts radio wave communication signals into infrared communication signals and infrared communication signals into radio wave communication signals. The repeater 91 has an appearance similar to a dedicated remote controller for a home appliance, and has only one button 91a (shown in FIG. 4). When the repeater 91 receives a predetermined radio wave communication signal from the information terminal 92 after the button 91a is pressed, the repeater 91 converts the radio wave communication signal into an infrared communication signal and transmits it to the detection device 62.

[0061] The information terminal 92 is a portable information terminal carried by a user who performs the setting (hereinafter, also referred to as a setting person). Specifically, the information terminal 92 is a portable terminal such as a smartphone or a tablet terminal. Specifically, the information terminal 92 includes an operation receiving unit 93, a display unit 94, a communication unit 95, an information processing unit 96, and a storage unit 97.

[0062] The operation reception unit 93 receives operations from a person who sets the settings. Specifically, the operation reception unit 93 is realized by a touch panel or the like.

[0063] The display unit 94 is a display on which an image is displayed, and is realized by, for example, a display panel such as a liquid crystal panel or an organic EL panel.

[0064] The communication unit 95 communicates with the detection device 62 and the repeater 91 in a second wireless communication method. The second wireless communication method is a communication method using radio waves, and the communication unit 95 is realized by, for example, a radio communication module (radio communication circuit). Note that the communication standard for the radio communication is, for example, BLE, but is not particularly limited.

[0065] The information processing unit 96 performs various settings of the detection device 62 by transmitting a setting command to the detection device 62 or the repeater 91 using the communication unit 95. The information processing unit 96 is realized by, for example, a microcomputer, but may also be realized by a processor or a dedicated circuit. The functions of the information processing unit 96 are realized by hardware such as a microcomputer or a processor constituting the information processing unit 96 executing a computer program (software) stored in the storage unit 97.

[0066] The storage unit 97 is a storage device that stores information necessary for the various settings. The information stored in the storage unit 97 includes computer programs executed by the information processing unit 96. The computer programs stored in the storage unit 97 include a predetermined application program (hereinafter also referred to as a predetermined app) for setting the detection device 62 that is installed in advance in the storage unit 97 by the user. Various display screens described below are displayed on the display unit 94 by the information processing unit 96 executing the predetermined app. The storage unit 97 is realized by, for example, a semiconductor memory or the like.

[0067] [Two communication methods in the configuration] In the setting system 90 described above, a setting person performs a predetermined operation on the information terminal 92 running the predetermined application. The predetermined operation is, for example, a tap operation on a send button displayed on the display unit 94. The operation reception unit 93 receives the predetermined operation, and the information processing unit 96 transmits a setting command to the detection device 62 using the communication unit 95 based on the received predetermined operation. The setting unit 67a of the detection device 62 performs setting based on the received setting command. As a result, the setting intended by the setting person is reflected in the detection device 62.

[0068] Two methods are used in combination to transmit the setting command. One of the two methods is a first method in which the information terminal 92 and the repeater 91 are wirelessly paired with each other using a second wireless communication method (radio waves), and then the repeater 91 transmits a setting command to the detection device 62 using the first wireless communication method (infrared). The other of the two methods is a second method in which the information terminal 92 and the detection device 62 are wirelessly paired with each other using the second wireless communication method (radio waves), and then the information terminal 92 transmits a setting command to the detection device 62 using the second wireless communication method (radio waves) without using the repeater 91.

[0069] For example, when a large number of detection devices 62 are installed in an indoor space and initial settings are performed sequentially on the multiple detection devices 62, the above-mentioned second method requires repeated connection and disconnection of the wireless pairing between the information terminal 92 and the detection devices 62, which has the drawback of taking time for setting up.

[0070] In such a case, the person setting up the system can use the first method described above to wirelessly pair the information terminal 92 with the repeater 91, and then sequentially send setting commands from the repeater 91 to a number of detection devices 62 using the first wireless communication method (infrared), thereby shortening the time required for setting up.

[0071] In addition, since the first wireless communication method (infrared) has directionality, it is necessary to point the repeater 91 toward the detection device 62 to be configured when communicating between the repeater 91 and the detection device 62. For this reason, it can be said that the first method has the effect of making it easier for the person configuring to grasp the detection device 62 to be configured (making configuration errors less likely to occur).

[0072] On the other hand, the first wireless communication method (infrared) has a relatively slow communication speed and is therefore not suitable for settings involving a large amount of communication, such as settings that require sending an image captured by the imaging unit 63 of the detection device 62 to the information terminal 92. In such cases, the person who sets the method can shorten the communication time by using the second method described above to wirelessly pair the information terminal 92 and the detection device 62 and have the information terminal 92 and the detection device 62 communicate with each other using the second wireless communication method.

[0073] [Setting items] Here, a description will be given of the setting items of the detection device 62. Fig. 5 is a diagram showing the setting items of the detection device 62, specifically, a diagram showing an example of a menu screen for setting the detection device 62 displayed on the display unit 94 of the information terminal 92.

[0074] As shown in FIG. 5, the setting items of the detection device 62 are roughly divided into three types: setting items related to construction work, setting items related to detailed work, and setting items related to inspection work.

[0075] Fig. 6 is a diagram showing an example of a setting screen for construction work. As shown in Fig. 6, the settings for construction work include settings for detection areas, such as a setting for how many detection areas to divide, a setting for addresses for the detection areas, and a setting for an arrangement pattern of the detection areas. Although not shown, the setting items for construction work also include a setting for the installation height of the detection device 62, and a setting for an absence hold time indicating how long the light emission of the lighting device 61a (or the lighting device 61b) should continue after the detection device 62 detects the absence of a person.

[0076] Fig. 7 is a diagram showing an example of a detailed work setting screen. As shown in Fig. 7, the detailed work settings include custom settings (detailed settings) related to the detection area, sensor-related settings, and image processing-related settings.

[0077] Furthermore, although not shown, on the inspection work setting screen, it is possible to set the detection device 62 to execute a special operation for inspection.

[0078] In the setting system 90, in consideration of the actual situation of settings, the setting items related to construction work and the setting items related to inspection work can be set using either the first method (infrared) or the second method (radio waves) described above, but the setting items related to detailed work can be set only using the second method out of the first and second methods. In other words, if the setting items that can be set using the first method (first wireless communication method) are defined as the first setting items, and the setting items that can be set using the second method (second wireless communication method) are defined as the second setting items, the first setting items and the second setting items only partially overlap, and the second setting items include more setting items than the first setting items.

[0079] In this case, the setting items related to the construction work, including the setting items related to the detection area, are overlapping setting items. In other words, when setting the setting items related to the construction work, it is possible to use either the first method or the second method.

[0080] Furthermore, the setting items related to images captured by the imaging unit 63 of the detection device 62 (setting items with high communication volume, included in the setting items for detailed work) are included in the second setting items, but not in the first setting items. In other words, the setting items related to images cannot be set in the first method, which has a slower communication speed than the second method. This prevents the setting of the setting items related to images from being executed in the first method (infrared), which has a slower communication speed, thereby preventing the occurrence of communication timeouts and the like.

[0081] The above-mentioned three types of setting items may be set by using either the first method or the second method. In other words, the first setting items and the second setting items may be the same. This allows the setting person to flexibly select whether to use the first method or the second method for all setting items. It is sufficient that the first setting items and the second setting items overlap at least partially.

[0082] [Detection area settings] As shown in Fig. 7 above, the settings related to the detailed work include custom settings (detailed settings) related to the detection area. The custom settings related to the detection area will be specifically described below. Fig. 8 is a diagram showing an example of an area setting screen for setting the detection area, which is displayed on the display unit 94 of the information terminal 92. Note that in the following description of the setting of the detection area, various operations (such as change operations described later) on the area setting screen are accepted by the operation acceptance unit 93, and the area setting screen is updated by the information processing unit 96, but the description of this point will be omitted as appropriate.

[0083] 8 displays an image of an indoor space (such as an image of a desk and chair seen from the ceiling side) actually captured by the imaging unit 63 of the detection device 62. The setter sets multiple detection areas for the image, thereby setting multiple detection areas for the imaging range of the imaging unit 63 in the actual indoor space. To display the image on the display unit 94, the information processing unit 96 of the information terminal 92 instructs the detection device 62 to capture an image and acquires the image from the detection device 62. The communication unit 95 is used to instruct the detection device 62 to capture the image and to acquire the image.

[0084] On the image, a plurality of currently set detection areas and a predetermined grid pattern serving as a guide for setting the detection areas are superimposed. The grid pattern is formed by, for example, arranging rectangular (more specifically, square) grid units in a matrix. Note that the grid units may be triangles, rhombuses, parallelograms, hexagons, or the like. The grid units are the smallest units for changing the detection areas. Changing the detection areas specifically means changing the layout and size of the detection areas.

[0085] In the example of FIG. 8, nine detection areas (1) to (9) are set in the image. The nine detection areas actually have different semi-transparent colors, but since color display is not possible in FIG. 8, they are distinguished by assigning numbers (1) to (9) for convenience. It is not essential that the detection areas are distinguished by color, and the detection areas may be distinguished by letters, numbers, symbols, or the like. In this way, the nine detection areas are distinguished by color, but they may also be distinguished by shades of a single color, may be distinguished by a pattern, or may be distinguished by being assigned an icon. In other words, it is sufficient that the nine detection areas have different display modes from one another and each can be uniquely identified.

[0086] The person setting the area first selects the arrangement pattern of the detection areas. When the "Area Setting" field in FIG. 8 is operated, a selection screen for the arrangement pattern of the detection areas is displayed. FIG. 9 is a diagram showing an example of the selection screen for the arrangement pattern of the detection areas. In the example of FIG. 9, a selection screen for the arrangement pattern when the number of detection areas (the number of divisions of the entire area) is four is displayed. Although not shown, a selection screen for the arrangement pattern when the number of detection areas is nine is also prepared. The "Area Setting" field can be said to be an operation area for setting multiple detection areas of a predetermined pattern for an image.

[0087] The arrangement pattern of the detection areas can be changed not only on the area setting screen of Fig. 8 but also on the construction work setting screen of Fig. 6. The number of detection areas (the number of divisions of the entire area) can be changed on the construction work setting screen of Fig. 6, but it may also be possible to change it from the area setting screen of Fig. 8. In this case, an operation area (icon, etc.) for changing the number of detection areas is provided on the area setting screen of Fig. 8 or the selection screen of Fig. 9.

[0088] Next, the setter selects an editing method. There are prepared editing methods, a first editing method in which the change operation for changing the detection area is an operation of selecting a grid unit, and a second editing method in which the change operation is an operation of moving an intersection of the boundary line of the detection area. The setter can switch from the first editing method to the second editing method and from the second editing method to the first editing method by operating the editing method switching icon 94e.

[0089] Note that the image displayed on the area setting screen (such as an image of a desk and chair seen from the ceiling side) does not change before and after switching the editing method. In other words, the image displayed on the area setting screen before switching the change operation of the detection area will also be displayed on the area setting screen after switching the change operation. Also, when switching the editing method, the editing state of the detection area immediately before switching is maintained, but the editing state of the state of the detection area may be reset.

[0090] First, the first editing method will be described. In the first editing method, the setter selects one of area 1 (corresponding to detection area (1)) to area 9 (corresponding to detection area (9)) in the "Setting target" field on the area setting screen in Fig. 8, and then selects a lattice unit in the lattice pattern. As a result, the selected lattice unit is changed to the detection area of ​​the setting target.

[0091] For example, the user selects area 1 in the "setting target" field, and then taps a lattice unit included in a detection area other than detection area (1) in the lattice pattern. This changes the tapped lattice unit to detection area (1), and the color of the tapped lattice unit changes to the color of detection area (1). When selecting a lattice unit, the user can continuously change the lattice unit by performing a swipe operation instead of a tap operation.

[0092] In addition, a single detection area (1) can be set in the image, or multiple separate detection areas (1) can be set. Setting multiple separate detection areas (1) may be prohibited since it may be undesirable in practice.

[0093] In the "Setting target" field, a non-detection area can be selected in addition to areas 1 to 9. A non-detection area is an area that appears in an image captured by the imaging unit 63 of the detection device 62, but is not included in the detection target when detecting a person or illuminance.

[0094] If the user selects a non-detection area in the "setting target" field and then taps a grid unit included in detection area (1) to detection area (9) in the grid pattern, the tapped grid unit will be changed to a non-detection area. Fig. 10 is a diagram showing an example of an area setting screen in which a non-detection area has been set, and the grid units hatched with dots correspond to the non-detection areas.

[0095] Thus, in the first editing method, the change operation for changing the multiple detection areas performed on the area setting screen is an operation for selecting a lattice unit, and the lattice unit selected by the change operation is changed to one of the multiple detection areas or to a non-detection area.

[0096] Next, the second editing method will be described. In the second editing method, circular icons 94f are displayed at the intersections of the boundaries of a plurality of detection areas. Fig. 11 is a diagram showing an example of an area setting screen when the second editing method is selected. In the example of Fig. 11, a total of 16 icons 94f are displayed.

[0097] The person setting the area can change the detection area by dragging and moving the icon 94f (intersection of the boundary lines) on the area setting screen in Fig. 11. Fig. 12 is a diagram showing an example of the area setting screen after the dragging operation.

[0098] As shown in Fig. 12, when the icon 94f is moved, the boundary line moves accordingly, resulting in a change in the detection area. In other words, the operation of moving the icon 94f is also the operation of moving the boundary line. Note that the icon 94f can be moved in units of lattices (lattice unit = minimum movement unit), but it may also be moved in units smaller than the lattice unit (lattice unit > minimum movement unit).

[0099] Here, as described above, the grid unit in the grid pattern is the minimum unit for changing the detection area. As shown in Fig. 12, if the boundary line does not follow the grid pattern as a result of moving the icon 94f, the boundary line is automatically reshaped to follow the grid pattern. Fig. 13 is a diagram showing an example of the area setting screen after the boundary line has been reshaped. As can be seen by comparing Fig. 12 and Fig. 13, the boundary line that was diagonal to the grid pattern in Fig. 12 has been reshaped into a staircase shape that follows the grid pattern in Fig. 13.

[0100] In addition, the detection area to which a lattice unit located on a boundary line before shaping belongs is determined by dividing the lattice unit at the boundary line before shaping and determining the area of ​​the small pieces of the lattice unit obtained by the division. In other words, the detection area of ​​the lattice unit is determined to be the detection area to which the small piece having the largest area among the small pieces obtained from the lattice unit belongs.

[0101] Thus, in the second editing method, the change operation for changing the multiple detection areas performed on the area setting screen is an operation of moving the icon 94f. Note that instead of or in addition to the icon 94f, the boundary line itself may be the object of the operation. That is, in the second editing method, the change operation for changing the multiple detection areas performed on the area setting screen may be an operation of moving the boundary line. In this case, the setter can change the detection area by performing a drag operation or the like on the boundary line.

[0102] It is also possible to set a non-detection area in the second editing method. For example, by moving the icon 94f located on the outermost line surrounding a plurality of detection areas inward, a non-detection area is set in the outermost part of the image.

[0103] [Variations] In the above embodiment, the information terminal 92 includes the communication unit 95 that communicates using the second wireless communication method (radio waves) and does not include a communication unit that communicates using the first wireless communication method (infrared rays), but may include a communication unit that communicates using the first wireless communication method (infrared rays). In this case, the information terminal 92 can communicate with the detection device 62 using the first wireless communication method without using the repeater 91.

[0104] Also, in the above embodiment, an example has been described in which communication in the first wireless communication method and communication in the second wireless communication method are used in combination when one information terminal 92 and one detection device 62 communicate with each other. Here, the detection device 62 may communicate with the information terminal 92 in the second wireless communication method, and may communicate with a setting terminal other than the information terminal 92 (for example, a dedicated terminal for setting) in the first wireless communication method. In other words, when one information terminal 92 and one detection device 62 communicate with each other, it is not essential that communication in the first wireless communication method and communication in the second wireless communication method are used in combination, and the detection device 62 may communicate with different terminals for each wireless communication method.
