However, the embodiment and the modified example described below are merely examples of the present disclosure, and the present disclosure is not limited to the following embodiment and modified example. Even if it is not the following embodiment and modified example, various modifications are possible according to the design, etc., as long as it does not deviate from the technical idea of ​​the present disclosure.

[0011] (1) Overview First, an overview of a detection system 1 and a device control system 100 according to the embodiment will be described with reference to FIGS. 1 to 3. FIG.

[0012] The detection system 1 according to the present embodiment is used in a facility 500 such as an office building, a store, a school, or a factory, and is a system for detecting a detection target 400 in the facility 500. In the present embodiment, a case where the facility 500 is an office building will be described as an example. As shown in FIG. 3, the detection system 1 is attached to a ceiling 501 of the facility 500, for example, and detects a detection target 400 in the facility 500. The detection system 1 can detect at least one detection target 400 including a moving object. The moving object is, for example, a person H1. In the present embodiment, the detection target 400 includes a person H1 in the facility 500 and brightness in the facility 500. The brightness in the facility 500 is, for example, the illuminance of a floor surface 502 of the facility 500. That is, the detection system 1 according to the present embodiment can detect two detection targets 400.

[0013] Moreover, the device control system 100 according to the present embodiment is a system used in, for example, a facility 500, for controlling a control target such as a lighting fixture 22 installed in the facility 500. In the present embodiment, a case will be described as an example in which the device control system 100 is a lighting control system for controlling the lighting fixture 22.

[0014] As shown in Fig. 2, the detection system 1 according to this embodiment includes a detection unit 111 and a communication unit 12. The detection unit 111 can detect at least one detection target 400 including a moving object in each of a plurality of first areas (areas) 201-204 (see Fig. 4) based on an image captured by the imaging unit 13. The plurality of first areas 201-204 are set for a detection range 200 (see Fig. 4) including at least a part of an imaging range 300 (see Fig. 4) of the imaging unit 13. The communication unit 12 outputs a detection result of the detection unit 111 for each of the plurality of first areas 201-204 using identification information set for each of the plurality of first areas 201-204.

[0015] 1, the device control system 100 according to the present embodiment includes a detection system 1 and a specific control device 2. The specific control device 2 operates according to a detection result of a detection unit 111 of the detection system 1. The specific control device 2 includes at least one of a first control device 21 and a second control device 22 controlled by the first control device 21.

[0016] In the detection system 1 and the device control system 100 according to the present embodiment, the detection target 400 can be detected for each of the first areas 201 to 204. In addition, in the detection system 1 and the device control system 100 according to the present embodiment, identification information is set for each of the first areas 201 to 204. Therefore, the detection result of the detection unit 111 can be output for each of the first areas 201 to 204 while distinguishing the detection result of the detection unit 111 for each of the first areas 201 to 204. In other words, according to the detection system 1 and the device control system 100 according to the present embodiment, the detection result of the detection unit 111 can be output for each of the first areas 201 to 204 set for the detection range 200 of the detection unit 111.

[0017] (2) Details Next, the detection system 1 and the device control system 100 according to this embodiment will be described in detail with reference to FIGS.

[0018] As shown in Fig. 1, the device control system 100 according to this embodiment includes a plurality of detection systems 1, a plurality of specific control devices 2, and a transmission unit 3. The plurality of specific control devices 2 include a plurality of first control devices 21 and a plurality of second control devices 22 that correspond one-to-one to the plurality of first control devices 21. In this embodiment, each of the plurality of first control devices 21 is a control terminal (hereinafter also referred to as "control terminal 21"). Also, in this embodiment, each of the plurality of second control devices 22 is a lighting device (hereinafter also referred to as "lighting device 22"). That is, each of the plurality of second control devices 22 is a device controlled by the corresponding first control device 21 among the plurality of first control devices 21.

[0019] Each of the multiple detection systems 1 and each of the multiple control terminals 21 are electrically connected to a two-wire signal line 4. The transmission unit 3 is electrically connected to the signal line 4 and communicates with each of the multiple detection systems 1 and each of the multiple control terminals 21.

[0020] In the device control system 100 according to this embodiment, data is transmitted and received by a transmission signal consisting of, for example, a bipolar (±24V) time division multiplexed signal. That is, in the device control system 100 according to this embodiment, data is transmitted between the transmission unit 3 and each detection system 1 and each control terminal 21 by transmitting and receiving a transmission signal via the signal line 4 according to a polling / selecting protocol.

[0021] (2.1) Control Terminal Control terminal 21 is configured integrally with lighting fixture 22 to be controlled. Note that control terminal 21 may be separate from lighting fixture 22 to be controlled. In this case, control terminal 21 is electrically connected to lighting fixture 22 or a relay provided on the power supply path of lighting fixture 22. Control terminal 21 has a function of controlling lighting fixture 22, such as turning it on / off, dimming, or adjusting its color, in accordance with a transmission signal sent from transmission unit 3.

[0022] (2.2) Detection System 2, the detection system 1 includes a control unit 11, a communication unit 12, an imaging unit 13, an infrared receiving unit 14, a setting unit 15, and a storage unit 16. In this embodiment, the imaging unit 13 and the infrared receiving unit 14 are included in the detection system 1, but they do not have to be included. In other words, the outputs of the imaging unit 13 and the infrared receiving unit 14 may be input to the detection system 1.

[0023] 3, the detection system 1 further includes a housing 10. The housing 10 has a circular shape when viewed from the front (the shape of the housing 10 attached to the ceiling 501 of the facility 500 when viewed from below). In this embodiment, a control unit 11, a communication unit 12, an imaging unit 13, an infrared receiving unit 14, a setting unit 15, and a storage unit 16 are stored in the housing 10. That is, the detection system 1 according to this embodiment is an image sensor device in which all functions are integrated.

[0024] (2.2.1) Control section The control unit 11 is configured, for example, with a microcomputer having a processor and a memory. That is, the control unit 11 is realized by a computer system having a processor and a memory. Then, the processor executes an appropriate program, so that the computer system functions as the control unit 11 (including the detection unit 111). The program may be pre-recorded in the memory, or may be provided via a telecommunication line such as the Internet, or recorded on a non-transitory recording medium such as a memory card.

[0025] The control unit 11 includes a detection unit 111. The detection unit 111 has a human detection function of detecting a human H1 present within a detection range 200 including at least a part of an imaging range 300 of the imaging unit 13 based on an image captured by the imaging unit 13. The detection unit 111 also has a brightness detection function of detecting brightness within the detection range 200 based on the image. Here, in the detection system 1 according to the present embodiment, the detection range 200 of the detection unit 111 can be divided into a plurality of first areas 201 to 204 by an area setting unit 153 described later. Then, the detection unit 111 executes a human detection function and a brightness detection function for each of the plurality of first areas 201 to 204. That is, in the detection system 1 according to the present embodiment, the detection unit 111 can detect a plurality of detection targets 400 for each of the plurality of first areas 201 to 204. Also, in the detection system 1 according to the present embodiment, the detection result of the detection unit 111 includes human information related to a person. In this embodiment, the person information includes presence / absence information indicating whether or not a person H1 is present within the detection range 200, and number-of-people information indicating the number of people H1 present within the detection range 200. Furthermore, in the detection system 1 according to this embodiment, the detection result of the detection unit 111 includes information related to the surrounding environment. In this embodiment, the information related to the surrounding environment is brightness information within the facility 500, specifically, information related to the illuminance of the floor surface 502 of the facility 500.

[0026] Further, the detection unit 111 can detect a person H1 present within a detection range (second areas 205-208 described below) of the infrared receiving unit 14 based on infrared rays received by the infrared receiving unit 14. As shown in Fig. 3, the detection system 1 according to this embodiment has a plurality of (four in Fig. 3) infrared receiving units 14. The detection unit 111 can detect the presence or absence of a person H1 in each of the plurality of second areas 205-208 that correspond one-to-one to the plurality of infrared receiving units 14.

[0027] As shown in FIG. 4, the second area 205 is set to include the first area 201 of the multiple first areas 201 to 204. As shown in FIG. 4, the second area 206 is set to include the first area 202 of the multiple first areas 201 to 204. As shown in FIG. 4, the second area 207 is set to include the first area 203 of the multiple first areas 201 to 204. As shown in FIG. 4, the second area 208 is set to include the first area 204 of the multiple first areas 201 to 204. That is, in the detection system 1 according to this embodiment, the detection unit 111 detects the presence or absence of a person H1 for each of the multiple second areas 205 to 208 that at least partially overlap with the multiple first areas 201 to 204 based on the infrared light received by the infrared receiving unit 14.

[0028] In the present disclosure, the term "detection range" refers to an area included in a plane at the detection height for detecting the detection target 400. For example, when the detection target 400 is the brightness within a facility 500, the plane is the floor surface 502 of the facility 500, and the detection range is the area included in the floor surface 502.

[0029] The control unit 11 is configured to control the communication unit 12, the imaging unit 13, and the infrared receiving unit 14 separately.

[0030] (2.2.2) Communications Section The communication unit 12 is a communication interface for communicating with the transmission unit 3. The communication unit 12 has a function of receiving a transmission signal transmitted from the transmission unit 3 and a function of transmitting a transmission signal to the transmission unit 3. That is, the communication unit 12 is configured to enable two-way communication with the transmission unit 3. In this embodiment, the communication unit 12 outputs the detection result of the detection unit 111 for each of the first areas 201 to 204 using identification information set for each of the first areas 201 to 204. The communication unit 12 outputs output information of a human detection function and output information of a brightness detection function, which will be described later, to the transmission unit 3 as the detection result of the detection unit 111.

[0031] (2.2.3) Imaging unit The imaging unit 13 has a two-dimensional image sensor (imaging element) such as a CCD (Charge Coupled Devices) image sensor or a CMOS (Complementary Metal-Oxide Semiconductor) image sensor. The imaging unit 13 captures, for example, a color image. Therefore, in the detection system 1 according to this embodiment, the brightness inside the facility 500 included in the imaging range 300 can also be detected based on the image captured by the imaging unit 13.

[0032] Here, in the detection system 1 according to this embodiment, the imaging range 300 of the imaging unit 13 coincides with the detection range 200 of the detection unit 111 (see FIG. 4). In other words, in the detection system 1 according to this embodiment, the detection range 200 of the detection unit 111 is set to be the same size as the imaging range 300 of the imaging unit 13. Note that the detection range 200 of the detection unit 111 need only include at least a part of the imaging range 300 of the imaging unit 13, and does not need to be the same size as the imaging range 300 of the imaging unit 13.

[0033] 3, the imaging unit 13 is disposed at approximately the center of the circular housing 10, and is installed on the ceiling 501 of the facility 500. Note that the imaging unit 13 only needs to be installed on the ceiling 501 side, and may be installed on, for example, a skeleton ceiling.

[0034] (2.2.4) Infrared receiver The infrared receiving unit 14 is, for example, a PIR (Passive Infrared) sensor. The infrared receiving unit 14 detects infrared rays emitted from a human body. Specifically, when the person H1 enters the detection range (any of the second areas 205 to 208) of the infrared receiving unit 14, the amount of infrared rays incident on the infrared receiving unit 14 changes by an amount corresponding to the temperature difference between the surface of the human body and the background, thereby making it possible to capture the movement of the person H1.

[0035] As shown in Fig. 3, the detection system 1 according to this embodiment includes a plurality of (four in Fig. 3) infrared receiving units 14. The plurality of infrared receiving units 14 are arranged at equal intervals around an imaging unit 13 located at the center of a circular housing 10.

[0036] (2.2.5) Setting section The setting unit 15 is configured to perform various settings related to the detection system 1. As shown in FIG. 2 , the setting unit 15 has an identification information setting unit 151, a detection range setting unit 152, an area setting unit 153, a function setting unit 154, and an information setting unit 155.

[0037] The identification information setting unit 151 sets a unique address (identification information) to be assigned to each of the multiple first areas 201-204 set in the detection range 200 of the detection unit 111. The unique address assigned to each of the multiple first areas 201-204 includes a first address and a second address. The first address is an address for transmitting information on the brightness in the facility 500 (information on the illuminance of the floor surface 502) as a detection result of the detection unit 111. The second address is an address for transmitting information on the person H1 in the facility 500 as a detection result of the detection unit 111. That is, in the detection system 1 according to this embodiment, the identification information setting unit 151 can set a first address and a second address for each of the multiple first areas 201-204. In other words, the identification information set for each of the multiple first areas 201-204 is set for each of the multiple detection targets 400 for each of the multiple first areas 201-204.

[0038] Here, in the detection system 1 according to the present embodiment, the identification information setting unit 151 has a setting mode. The setting mode is a mode in which identification information is set for a specific area, which is one of the multiple first areas 201 to 204, to automatically set identification information for the other areas excluding the specific area. For example, when the first area 201 of the multiple first areas 201 to 204 is set as a specific area and identification information is set for the first area 201, the identification information setting unit 151 sets identification information for the first areas 202 to 204, which are the other areas excluding the specific area. Specifically, in the setting mode, for example, when an address of "1" is set for the first area 201, the identification information setting unit 151 sets addresses of "2", "3", and "4" for the remaining first areas 202 to 204. The address setting for the first area 201 can be performed using the remote control (setter) 6. That is, in the detection system 1 according to this embodiment, the identification information setting unit 151 has a setting mode in which identification information (address) is set for a specific area (first area 201) based on an input from the outside (remote control 6) to set identification information for other areas (first areas 202-204). This makes it possible to set identification information for all areas (specific area and other areas) simply by setting identification information for the specific area. As a result, it is possible to reduce the time required to set identification information for the first areas 201-204.

[0039] The detection range setting unit 152 is configured to set the detection range 200 of the detection unit 111 with respect to the imaging range 300 of the imaging unit 13. The detection range setting unit 152 sets, for example, whether or not to detect the detection target 400 for each unit area 301 (see FIG. 4) constituting the imaging range 300. The unit area 301 is, for example, an area constituted by a plurality of pixels, but may be set in pixel units. In this embodiment, the detection range setting unit 152 sets all the unit areas 301 to detect the detection target 400, and as a result, the detection range 200 of the detection unit 111 is set to the same size as the imaging range 300 of the imaging unit 13 (see FIG. 4).

[0040] The area setting unit 153 can set a plurality of first areas 201-204 in the detection range 200 of the detection unit 111. The area setting unit 153 can change the number of divisions of the plurality of first areas 201-204. This allows the detection range 200 of the detection unit 111 to be set as one first area 201, as two first areas 201 and 202, or as four first areas 201-204. As shown in FIG. 4, the area setting unit 153 can set the plurality of first areas 201-204 in a size smaller than the plurality of second areas 205-208, which are the detection ranges of the plurality of infrared receiving units 14. The area setting of the detection range 200 will be described in detail in the section "(3) Area Setting".

[0041] The function setting unit 154 is configured to set the function of the detection unit 111 according to the height information input using the remote control 6. That is, the function setting unit 154 acquires height information based on an input from the outside (for example, the remote control 6). The height information is information about the height at which the imaging device including the imaging unit 13 is installed. In this embodiment, the height information is the height dimension to the ceiling 501 of the facility 500 in which the detection system 1 is installed. For example, in the case of a first person detection function of the human detection function that detects whether or not a person H1 exists within the detection range 200, the function setting unit 154 enables the first person detection function if the height dimension is 2.4 m or more and 4.5 m or less. In addition, in the case of a second person detection function of the human detection function that detects the number of people H1 existing within the detection range 200, the function setting unit 154 enables the second person detection function if the height dimension is 2.8 m or more and 8.0 m or less. In addition, in the case of the brightness detection function, the function setting unit 154 enables the brightness detection function if the height dimension is 2.4 m or more and 8.0 m or less. In this way, the function setting unit 154 can set the function of the detection unit 111 according to the height information.

[0042] Furthermore, function setting unit 154 is configured to restrict functions according to height information input using remote control 6. For example, in the case of the first person detection function, if the height is 4.6 m or more, function setting unit 154 disables the first person detection function and fixes the detection result of detection unit 111 to "present". In the case of the second person detection function, if the height is less than 2.8 m, function setting unit 154 disables the second person detection function and stops output of the detection result of detection unit 111.

[0043] Here, the detection system 1 according to this embodiment has both the imaging unit 13 and the infrared receiving unit 14 as described above. That is, the detection unit 111 has a first function of detecting the detection target 400 based on the image captured by the imaging unit 13, and a second function of detecting the detection target 400 based on the infrared light received by the infrared receiving unit 14. Therefore, it is preferable that the function setting unit 154 is configured to set at least one of the first function and the second function to be enabled / disabled according to the height information. This allows at least one of the first function and the second function to be enabled / disabled. In this embodiment, the function setting unit 154 can set both the first function and the second function to be enabled / disabled.

[0044] In addition, as in this embodiment, when the detection target 400 is detected based on the image captured by the imaging unit 13 and the output of another sensor (infrared receiving unit 14) different from the imaging unit 13, it is preferable to vary the combination of the imaging unit 13 and the other sensor depending on the height information. For example, when the height dimension is 4.5 m or less, the infrared receiving unit 14 functions normally, so the detection target 400 (person H1) is detected based on the output of the imaging unit 13 and the infrared receiving unit 14. On the other hand, when the height dimension is 4.6 m or more, the infrared receiving unit 14 may not function normally, so the detection target 400 is detected based on the output of only the imaging unit 13. In this way, by changing the combination of the imaging unit 13 and the other sensor depending on the height at which the imaging unit 13 is installed, the detection target 400 (person H1) can be detected regardless of the height.

[0045] Furthermore, it is preferable that the height information is also used for settings related to the imaging unit 13. For example, for the imaging unit 13, the focal length to the detection target 400 can be set by inputting the height information. This has the advantage that it is not necessary to input height information for setting the imaging unit 13.

[0046] The information setting unit 155 is configured to set output information based on the detection result of the detection unit 111 for each of the multiple functions. In the detection system 1 according to the present embodiment, the detection unit 111 has a human detection function and a brightness detection function. That is, the detection unit 111 has multiple functions. Therefore, the information setting unit 155 sets output information for the human detection function and sets output information for the brightness detection function. For example, for the first human detection function among the human detection functions, if the height dimension is 4.6 m or more, the information setting unit 155 sets information indicating "presence" or "absence" to the output information. Also, for example, for the first human detection function, if the height dimension is 2.4 m or more and 4.5 m or less, the information setting unit 155 sets the detection result of the detection unit 111 to the output information. In this way, the information setting unit 155 can set output information for each of the multiple functions.

[0047] (2.2.6) Storage section The storage unit 16 is configured with a device selected from, for example, a read-only memory (ROM), a random access memory (RAM), an electrically erasable programmable read-only memory (EEPROM), and the like.

[0048] The storage unit 16 stores the detection range 200 set by the detection range setting unit 152. The storage unit 16 also stores the first areas 201-204 set by the area setting unit 153. The storage unit 16 also stores the identification information (first address, second address) set by the identification information setting unit 151. The storage unit 16 also stores height information of the detection system 1 input using the remote control 6. The storage unit 16 also stores the enable / disable of the human detection function, the enable / disable of the brightness detection function, the enable / disable of the first function, and the enable / disable of the second function. The storage unit 16 also stores the output information set by the information setting unit 155 in association with each function.

[0049] (2.3) Transmission Unit The transmission unit 3 individually identifies the multiple detection systems 1 using a unique address (identification information) assigned to each of the multiple detection systems 1. In this embodiment, each detection system 1 is assigned a unique address (first address and second address) for each of the multiple first areas 201-204 set in the detection range 200 of the detection unit 111. Therefore, the transmission unit 3 recognizes the multiple first areas 201-204 individually using the unique address assigned to each of the multiple first areas 201-204. Also, in this embodiment, the multiple control terminals 21 are individually identified using the unique address assigned to each of the multiple control terminals 21.

[0050] (3) Area setting Next, the area setting for setting the first areas 201-204 in the detection range 200 of the detection unit 111 will be described with reference to Figs. 5A-5F. In Figs. 5A-5F, the detection range 200 is configured with 8 rows x 8 columns of unit areas 301, with 8 unit areas 301 lined up in the first direction (the left-right direction in Figs. 5A-5F) and 8 unit areas 301 lined up in the second direction (the up-down direction in Figs. 5A-5F). Note that the number of unit areas 301 in the first and second directions is just an example and is not limited to 8.

[0051] In the detection system 1 of this embodiment, as shown in Figures 5A to 5F, the first area can be set by inputting the number of unit areas 301 in the first direction and the number of unit areas 301 in the second direction.

[0052] 5A, the installer uses the remote control 6 to input "0" as the number of unit areas 301 in the first direction, input "0" as the number of unit areas 301 in the second direction, and then transmits this input data to the detection system 1. The area setting unit 153 sets one first area 201 based on the input data from the remote control 6. That is, in this case, the first area 201 coincides with the detection range 200 of the detection unit 111.

[0053] In FIG. 5B, the installer uses the remote control 6 to input "0" as the number of unit areas 301 in the first direction and "3" as the number of unit areas 301 in the second direction, and then transmits this input data to the detection system 1. The area setting unit 153 sets two first areas 201, 202 divided in the second direction by a boundary L2 based on the input data from the remote control 6. The first area 201 is an area including a total of 40 unit areas 301 of 8 rows and 5 columns. The first area 202 is an area including a total of 24 unit areas 301 of 8 rows and 3 columns.

[0054] In FIG. 5C, the installer uses the remote control 6 to input "6" as the number of unit areas 301 in the first direction and "0" as the number of unit areas 301 in the second direction, and then transmits this input data to the detection system 1. The area setting unit 153 sets two first areas 201, 202 divided in the first direction by a boundary L1 based on the input data from the remote control 6. The first area 201 is an area including a total of 48 unit areas 301 of 6 rows and 8 columns. The first area 202 is an area including a total of 16 unit areas 301 of 2 rows and 8 columns.

[0055] In FIG. 5D, the installer uses the remote control 6 to input "4" as the number of unit areas 301 in the first direction, and input "4" as the number of unit areas 301 in the second direction, and then transmits this input data to the detection system 1. The area setting unit 153 sets four first areas 201-204 divided by boundaries L1 and L2 based on the input data from the remote control 6. Each of the first areas 201-204 is an area including a total of 16 unit areas 301 of 4 rows and 4 columns. The input data from the remote control 6 coincides with an intersection P1 of the boundaries L1 and L2.

[0056] In FIG. 5E, the installer inputs "3" as the number of unit areas 301 in the first direction and "4" as the number of unit areas 301 in the second direction using the remote control 6, and then transmits this input data to the detection system 1. The area setting unit 153 sets four first areas 201-204 divided by boundaries L1 and L2 based on the input data from the remote control 6. Each of the first areas 201 and 204 is an area including a total of 12 unit areas 301 of 3 rows and 4 columns. Each of the first areas 202 and 203 is an area including a total of 20 unit areas 301 of 5 rows and 4 columns. The input data from the remote control 6 coincides with the intersection P1 of the boundaries L1 and L2.

[0057] In FIG. 5F, the installer inputs "5" as the number of unit areas 301 in the first direction and "5" as the number of unit areas 301 in the second direction using the remote control 6, and then transmits this input data to the detection system 1. The area setting unit 153 sets four first areas 201 to 204 divided by boundaries L1 and L2 based on the input data from the remote control 6. The first area 201 is an area including a total of 15 unit areas 301 of 5 rows and 3 columns. The first area 202 is an area including a total of 9 unit areas 301 of 3 rows and 3 rows. The first area 203 is an area including a total of 15 unit areas 301 of 3 rows and 5 columns. The first area 204 is an area including a total of 25 unit areas 301 of 5 rows and 5 rows. The input data from the remote control 6 coincides with the intersection P1 of the boundaries L1 and L2.

[0058] As described above, by inputting the number of unit areas 301 in the first direction and the number of unit areas 301 in the second direction, which are the intersection P1 of the boundaries L1 and L2, it is possible to arbitrarily set the first area for the detection range 200. In addition, by inputting the number of unit areas 301 in the first direction and the number of unit areas 301 in the second direction, it is also possible to set (change) the number of divisions of the first area.

[0059] Incidentally, it is preferable that area setting unit 153 is configured to set a plurality of first areas 201-204 according to the output destination or use of the detection result of detection unit 111. For example, when one lighting fixture 22 is associated with detection range 200 of detection unit 111, one first area 201 is set. On the other hand, when four lighting fixtures 22 are associated with detection range 200 of detection unit 111, four first areas 201-204 are set. In this way, a plurality of first areas 201-204 can be set according to the output destination or use of the detection result of detection unit 111.

[0060] The area setting unit 153 may be configured to set different areas for detecting the person H1 and for detecting the surrounding environment. For example, four first areas 201-204 are set for detecting the person H1, and one first area 201 is set for detecting brightness as the surrounding environment.

[0061] (4) Operation Next, the operation of the detection system 1 according to this embodiment will be described.

[0062] (4.1) Setting operation First, the setting operation of the detection system 1 according to this embodiment will be described with reference to FIG.

[0063] The installer uses the remote control 6 to input settings for setting the detection range 200 (step S1). After that, the installer uses the remote control 6 to transmit the input information to the detection system 1 (step S2). In the detection system 1, the detection range setting unit 152 sets the detection range 200 based on the input information from the remote control 6 (step S3). In this embodiment, the detection range 200 is set to the same size as the imaging range 300 of the imaging unit 13. Then, the control unit 11 stores the detection range 200 set by the detection range setting unit 152 in the storage unit 16 (step S4).

[0064] The installer also uses the remote control 6 to input settings for setting the first areas 201-204 (step S5). After that, the installer uses the remote control 6 to transmit the input information to the detection system 1 (step S6). In the detection system 1, the area setting unit 153 sets the first areas 201-204 based on the input information from the remote control 6 (step S7). Then, the control unit 11 stores the first areas 201-204 set by the area setting unit 153 in the storage unit 16 (step S8).

[0065] Furthermore, the installer inputs addresses (first address and second address) to be assigned to each of the first areas 201-204 using the remote control 6 (step S9). After that, the installer transmits the input information to the detection system 1 using the remote control 6 (step S10). In the detection system 1, the identification information setting unit 151 sets addresses (identification information) for each of the first areas 201-204 based on the input information from the remote control 6 (step S11). Then, the control unit 11 stores the addresses set by the identification information setting unit 151 in the storage unit 16 in association with the first areas 201-204 (step S12).

[0066] In addition, the installer inputs height information regarding the height at which the detection system 1 (imaging unit 13) is installed using the remote control 6 (step S13). In this embodiment, height information can be input for each function of the detection unit 111, and height information can be input for each of the first person detection function, the second person detection function, and the brightness detection function. After that, the installer transmits the input information to the detection system 1 using the remote control 6 (step S14). In the detection system 1, the function setting unit 154 sets the function of the detection unit 111 based on the input information from the remote control 6 (step S15). For example, the function setting unit 154 sets the first person detection function, the second person detection function, and the brightness detection function to be enabled / disabled. In addition, when the first person detection function is set to be disabled, the function setting unit 154 sets the detection unit 111 to output "presence" information as detection information. In addition, when the second person detection function is set to be disabled, the function setting unit 154 sets the detection unit 111 not to output detection information. Then, the control unit 11 stores the contents set by the function setting unit 154 in the storage unit 16 (step S16).

[0067] The order in which the detection range, area, and address are set is merely an example, and for example, the detection range and address may be set in this order after the area is set, or the address and detection range may be set in this order after the area is set. The order in which height information is input is also merely an example, and for example, it may be input before the detection range is set, before the area is set, or before the address is set.

[0068] (4.2) Communication Operation Furthermore, the communication operations between the transmission unit 3 and the detection system 1 and the control terminal 21 will be described.

[0069] The transmission unit 3 executes polling until it detects an interrupt signal. In this disclosure, an "interrupt signal" is a current-mode signal that is generated on the signal line 4 by the detection system 1 that detects a monitoring input when at least one of the multiple detection systems 1 detects a monitoring input. In addition, in this disclosure, a "current-mode signal" is a signal represented by a current change that occurs when switching between a state in which the lines of the signal line 4 are open and a state in which a low impedance element is connected between the lines of the signal line 4.

[0070] In this embodiment, the monitoring inputs are an input that occurs when the first person detection function detects the presence of a person H1 within the facility 500, and an input that occurs when the brightness detection function detects a sudden change in the brightness (illuminance of the floor surface 502) within the facility 500. Note that, when multiple monitoring inputs occur simultaneously, the transmission unit 3 is configured to acquire the monitoring inputs in order, for example, from the smallest address.

[0071] In polling, the transmission unit 3 periodically transmits a transmission signal including a sequentially changing address to the signal line 4. When the address included in the transmission signal matches its own address, each of the multiple control terminals 21 acquires the control data included in the transmission signal. Then, each of the multiple control terminals 21 replies with the control status of the corresponding lighting fixture 22 as monitoring data. In this disclosure, "reply" refers to sending data to the transmission unit 3 by a current mode signal synchronized with a period defined as a reply band in the transmission signal transmitted from the transmission unit 3.

[0072] Furthermore, each of the multiple detection systems 1 acquires the control data included in the transmission signal when the address included in the transmission signal matches the address of any of the multiple first areas 201-204 included in the detection range 200 of the detection unit 111. Then, each of the multiple detection systems 1 returns the detection result of the detection unit 111 in the corresponding first area among the multiple first areas 201-204 as monitoring data.

[0073] When the transmission unit 3 detects an interrupt signal, it executes interrupt processing. In the interrupt processing, the transmission unit 3 transmits an interrogation signal to the signal line 4 to inquire about the detection system 1 that generated the interrupt signal. Then, when the detection system 1 that generated the interrupt signal receives the interrogation signal, it stops generating the interrupt signal and replies with its own address.

[0074] When there is a reply from the detection system 1 that is the source of the interrupt signal, the transmission unit 3 acquires the address of the detection system 1 that is the source of the interrupt signal, and identifies the detection system 1 that is the source of the interrupt signal. Then, the transmission unit 3 specifies the address of the detection system 1 that is the source of the interrupt signal and transmits a transmission signal including reply request data (hereinafter referred to as a "reply request signal").

[0075] When the detection system 1 which is the source of the interrupt signal receives the reply request data including its own address, it responds by sending back monitoring data.

[0076] When the transmission unit 3 acquires the monitoring data from the detection system 1 that is the source of the interrupt signal, it completes the interrupt process. Then, the transmission unit 3 transmits a transmission signal including control data (hereinafter referred to as a "control signal") to the control terminal 21 corresponding to the address included in the monitoring data. As a result, the control terminal 21 that receives the control signal controls the relay according to the control data included in the received control signal, thereby controlling the lighting device 22. Thereafter, the transmission unit 3 executes polling until an interrupt signal is generated again on the signal line 4.

[0077] (5) Effects In the detection system 1 and the device control system 100 according to the present embodiment, the detection target 400 can be detected for each of the first areas 201 to 204. In addition, in the detection system 1 and the device control system 100 according to the present embodiment, identification information is set for each of the first areas 201 to 204. Therefore, the detection result of the detection unit 111 can be output for each of the first areas 201 to 204 while distinguishing the detection result of the detection unit 111 for each of the first areas 201 to 204. In other words, according to the detection system 1 and the device control system 100 according to the present embodiment, the detection result of the detection unit 111 can be output for each of the first areas 201 to 204 set for the detection range 200 of the detection unit 111.

[0078] Furthermore, when the imaging unit 13 and the infrared receiving unit 14 are used in combination as in the detection system 1 according to this embodiment, the presence or absence of the person H1 can be detected even if the facility 500 is dark.

[0079] (6) Examples (6.1) Air conditioning control use Air conditioning control in offices mainly involves measuring the temperature, humidity, and CO2 concentration in the office space and providing feedback control to bring the temperature, humidity, and CO2 concentration closer to the target values. However, with the increase in column-free office buildings, sensor installation locations may be limited, and when temperature sensors are installed on walls, etc., the issue is that temperature changes at locations far from the sensor are not immediately reflected in the measured values. Therefore, by measuring the number of people, which is a factor that affects increases and decreases in temperature and CO2 concentration, and controlling the temperature control of air conditioning and the introduction of outside air before the changes in the temperature sensor and CO2 concentration sensor (feedforward control), it may be possible to provide air conditioning control that prioritizes comfort. For example, when many people gather in a certain area such as a conference room during summer cooling, the space temperature rises due to the heat generated by the people, but it may take time for the temperature sensor to capture that change and control the air conditioning. Therefore, it is thought that air conditioning can be controlled without causing discomfort to workers by measuring the number of people using an image sensor, and if there is a significant increase in the number of people, the set temperature can be lowered as an auxiliary measure.

[0080] (6.2) Visualization of office usage In recent years, with the growing interest in work style reform, various improvement measures are being considered in offices, but changes in work style before and after the improvement are often surveyed by questionnaires or visual observation by humans. However, because questionnaires tend to have subjective results and it is difficult to conduct continuous surveys by humans, there is a need for objective and continuous visualization of office usage status through sensing. For example, when the usage status of a meeting space is measured using an image sensor's headcount level (including classification of the number of people or the number of people into multiple categories), it is possible to relatively grasp the usage status of the meeting space depending on whether or not an event is taking place and the time of day.

[0081] (7) Variations The above-described embodiment is merely one of various embodiments of the present disclosure. The above-described embodiment can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. In addition, the same function as the detection system 1 according to the above-described embodiment may be embodied in a control method for the detection system 1, a computer program, or a non-transitory recording medium having a computer program recorded thereon, etc.

[0082] The control method of the detection system 1 according to one embodiment includes a detection step and a communication step. The detection step is a step capable of detecting at least one detection target 400 including a moving object in each of a plurality of first areas 201-204 set in a detection range 200 including at least a part of an imaging range 300 of the imaging unit 13 based on an image captured by the imaging unit 13. The communication step is a step of outputting a detection result of the detection step for each of the plurality of areas 201-204 using identification information (e.g., an address) set for each of the plurality of areas 201-204. The program according to one embodiment is a program for causing one or more processors to execute the control method of the detection system 1 described above.

[0083] Modifications of the above-described embodiment are listed below. The modifications described below can be applied in appropriate combination.

[0084] In the detection system 1 in the present disclosure, the control unit 11 includes a computer system. The computer system is mainly composed of a processor and a memory as hardware. The function of the detection system 1 in the present disclosure is realized by the processor executing a program recorded in the memory of the computer system. The program may be pre-recorded in the memory of the computer system, may be provided through an electric communication line, or may be provided by being recorded in a non-transitory recording medium such as a memory card, an optical disk, or a hard disk drive that can be read by the computer system. The processor of the computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). The integrated circuits such as IC or LSI referred to here are called by different names depending on the degree of integration, and include integrated circuits called system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale Integration). Furthermore, a field-programmable gate array (FPGA) that is programmed after the manufacture of the LSI, or a logic device that can reconfigure the connection relationship inside the LSI or the circuit partition inside the LSI, can also be adopted as a processor. The electronic circuits may be integrated in one chip or distributed among multiple chips. The chips may be integrated in one device or distributed among multiple devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Thus, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

[0085] Furthermore, it is not essential for the detection system 1 that multiple functions are integrated into one housing. That is, the components of the detection system 1 may be distributed across multiple housings. Furthermore, at least some of the functions of the detection system 1, for example, the functions of the control unit 11, may be realized by the cloud (cloud computing) or the like.

[0086] In the above-described embodiment, the detection system 1 includes both the imaging unit 13 and the infrared receiving unit 14, but the infrared receiving unit 14 may be omitted. Also, in the above-described embodiment, the detection system 1 includes the imaging unit 13, but the imaging unit 13 may be provided separately from the detection system 1. In this case, it is sufficient that the image captured by the imaging unit 13 is configured to be input to the detection system 1.

[0087] In the above embodiment, the imaging range 300 of the imaging unit 13 and the detection range 200 of the detection unit 111 coincide with each other. However, it is sufficient that the detection range 200 is set so as to include at least a part of the imaging range 300.

[0088] In the above embodiment, the moving object is person H1, but the moving object may be any object that moves and is not limited to person H1.

[0089] In the above embodiment, the information about the surrounding environment is brightness information, but the information about the surrounding environment is not limited to brightness information.

[0090] In the above embodiment, the detection system 1 includes the imaging unit 13 and the infrared receiving unit 14. However, for example, the detection system 1 may include the infrared receiving unit 14 and a brightness sensor. In this case, the presence or absence of a person H1 in the facility 500 can be detected by the infrared receiving unit 14, and the brightness (illuminance of the floor surface 502) in the facility 500 can be detected by the brightness sensor. That is, the detection system 1 may include a detection unit 111 and a function setting unit 154. The detection unit 111 detects at least one detection target 400 including a moving object based on the sensing result of a sensor unit (e.g., the infrared receiving unit 14 and the brightness sensor) installed on the ceiling 501 side. The function setting unit 154 sets the function of the detection unit 111 according to height information regarding the height at which the sensor unit is installed. This allows the function of the detection unit 111 to be set according to the height at which the sensor unit is installed.

[0091] In the above embodiment, the specific control device 2 includes both the first control device 21 and the second control device 22, but it is sufficient that the specific control device 2 includes at least one of the first control device 21 and the second control device 22. Therefore, the specific control device 2 may include only the first control device 21, may include only the second control device 22, or may include both the first control device 21 and the second control device 22.

[0092] In the above-described embodiment, the detection target 400 of the detection unit 111 is the person H1 and the brightness (illuminance) obtained from the image captured by the imaging unit 13, but the detection target 400 of the detection unit 111 need only include at least a moving object and does not have to include brightness.

[0093] In the above embodiment, the second control device is lighting fixture 22, but the second control device is not limited to lighting fixture 22 and may be, for example, air conditioning equipment such as an air conditioner or a ventilator. In this case, for example, the air conditioning equipment may be controlled according to the number of people H1 included in the image captured by imaging unit 13.

[0094] In the above embodiment, the function setting unit 154 restricts each function according to the height information of the imaging unit 13. However, the function setting unit 154 may be configured to release each function according to the height information. In other words, it is preferable that the function setting unit 154 can set the height information for each of the plurality of functions, at least a part of the function being restricted or released. In the present disclosure, "releasing a function" means enabling the function. For example, if the height information for the first human detection function among the human detection functions is set to 2.4 m or more and 4.5 m or less, the function setting unit 154 enables the first human detection function. According to this configuration, at least a part of the function can be restricted or released according to the height information for each of the plurality of functions.
