The facility control system 100 according to the present embodiment is used in, for example, a facility 500, and is a system for controlling control targets such as lighting fixtures 22 and air conditioners 24 installed in the facility 500.
(details)
Next, details of the image sensor device 1 and the device control system 100 according to the present embodiment will be described with reference to fig. 1 to 4.
As shown in fig. 1, the facility control system 100 according to the present embodiment includes a plurality of image sensor devices 1, a plurality of lighting devices 2, an air conditioning control device 23, an air conditioning device 24, and an integrated controller 3.
The plurality of lighting apparatuses 2 include a plurality of control devices 21 (control terminals) and a plurality of lighting fixtures 22 (loads) corresponding one-to-one to the plurality of control devices 21. The control device 21 performs control of on/off, dimming, color modulation, or the like of the corresponding illumination device 22 based on the output information of the image sensor apparatus 1. The lighting fixtures 22 are devices that illuminate the interior (i.e., the office) of the facility 500 according to the control of the corresponding control apparatus 21. Further, in the present embodiment, one lighting fixture 22 is provided for one control apparatus 21, but a plurality of lighting fixtures 22 may be provided for one control apparatus 21. The air conditioning control device 23 controls the on/off of the air conditioning device 24 or the air conditioning temperature based on the output information of the image sensor device 1.

(image sensor device)
As shown in fig. 2, the image sensor device 1 includes a control unit 11, a communication unit 12 (output unit), an imaging unit 13, an infrared light receiving unit 14, and a temperature sensor 17.
As shown in fig. 3, the image sensor device 1 further includes a housing 10. The shape of the front view of the casing 10 (the shape of the casing 10 attached to the ceiling 501 of the facility 500 as viewed from below) is circular. In the present embodiment, the control unit 11, the communication unit 12, the imaging unit 13, the infrared light receiving unit 14, and the temperature sensor 17 are housed in the case 10.
(control section)
The control unit 11 is constituted by a microcomputer having a processor and a memory, for example. 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, and the computer system functions as the control unit 11 (including the detection unit 111). The program may be stored in a memory in advance, or may be provided via a communication line such as the internet or stored in a non-transitory recording medium such as a memory card.
The control unit 11 includes a detection unit 111. The detection unit 111 has a person detection function of detecting a person H1 present in a detection range 200 including at least a part of the imaging range 300 of the imaging unit 13 based on the image captured by the imaging unit 13. The detection unit 111 has a brightness detection function of detecting brightness in the detection range 200 based on the image. Here, in the image sensor device 1 according to the present embodiment, the detection range 200 of the detection unit 111 is divided into a plurality of first regions 201 to 204. The detection unit 111 performs a human detection function and a brightness detection function for each of the plurality of first regions 201 to 204. That is, in the image sensor device 1 according to the present embodiment, the detection unit 111 can detect a plurality of detection objects 400 (the person H1 and the brightness in the detection range 200) for each of the plurality of first regions 201 to 204. In the image sensor device 1 according to the present embodiment, the detection result of the detection unit 111 includes person information about a person. In the present embodiment, the person information includes: movement/stay/absence information indicating whether the person H1 is moving, staying, or absent within the detection range 200; and head count information indicating the number of persons of the person H1 present in the detection range 200. That is, in the present embodiment, the human detection function has: a first person detection function of detecting whether the person H1 is moving, staying, or not present within the detection range 200; and a second person detection function of detecting the number of persons H1 present within the detection range 200. In the following description, the movement, stay, and absence may be simply referred to as presence or absence. In addition, the control unit 11 can output the detection result of the first detection function and the detection result of the second detection function from the communication unit 12 to the outside, but in this case, the control unit 11 can output the detection result of the first detection function and the detection result of the second detection function separately.
In the image sensor device 1 according to the present embodiment, the detection result of the detection unit 111 further includes information about the surrounding environment. In the present embodiment, the information on the surrounding environment is brightness information in the facility 500, specifically, information on the illuminance of the floor 502 of the facility 500.
The detection unit 111 can detect the person H1 present in the detection range of the infrared light receiving unit 14 (present in the second regions 205 to 208 described later) based on the infrared light received by the infrared light receiving unit 14. As shown in fig. 3, the image sensor device 1 according to the present embodiment includes a plurality of (four in fig. 3) infrared light receiving units 14. The detection unit 111 can detect the presence or absence of a person H1 for each of the plurality of second regions 205 to 208 corresponding one-to-one to the plurality of infrared light receiving units 14.
As shown in FIG. 4, the second region 205 is set to include the first region 201 among the plurality of first regions 201 to 204. As shown in FIG. 4, the second region 206 is set to include a first region 202 among the plurality of first regions 201 to 204. As shown in FIG. 4, the second region 207 is set to include the first region 203 among the plurality of first regions 201 to 204. As shown in FIG. 4, the second region 208 is set to include the first region 204 among the plurality of first regions 201 to 204. That is, in the image sensor device 1 according to the present embodiment, the detection unit 111 detects the presence or absence of the person H1 for each of the plurality of first regions 201 to 204 and the plurality of second regions 205 to 208 at least partially overlapping based on the infrared ray received by the infrared ray receiving unit 14.
In the present embodiment, the second regions 205 to 208, which are the detection ranges of the plurality of infrared light receiving units 14, are set so as to overlap the first regions 201 to 204 in the detection range 200, respectively, but the detection ranges (the second regions 205 to 208) of the plurality of infrared light receiving units 14 may be set so as not to overlap the detection range 200.
In the present embodiment, the detection range of the plurality of infrared light receiving units 14 is divided into a plurality of first regions 201 to 204 for each infrared light receiving unit 14. However, the detection range of the plurality of infrared light receiving units 14 may not be divided into the plurality of first regions 201 to 204 for each infrared light receiving unit 14. In this case, the detection ranges of the plurality of infrared light receiving units 14 are common among the plurality of infrared light receiving units 14, and are, for example, all ranges obtained by adding the plurality of first regions 201 to 204. In this case, when each of the plurality of infrared light receiving units 14 detects a person in any one of the first regions 201 to 204, the detection unit 111 determines that a person is detected in all the ranges obtained by adding the plurality of first regions 201 to 204.
The control unit 11 is configured to separately control the communication unit 12, the imaging unit 13, the infrared light receiving unit 14, and the temperature sensor 17.
(communication section)
The communication unit 12 is a communication interface for communicating with the integrated controller 3. In the present embodiment, the communication unit 12 outputs the detection result of the detection unit 111 (the presence or absence of the person H1 in the facility 500, the information on the number of persons, and the brightness) and the measurement result of the temperature sensor 17 (the information on the temperature in the facility 500) to the integrated controller 3. More specifically, the communication unit 12 can output the detection result of the detection unit 111 and the measurement result of the temperature sensor 17 to the integrated controller 3 for each of the plurality of first areas 201 to 204. That is, the communication unit 12 can output the detection result of the detection unit 111 and the measurement result of the temperature sensor 17 to the integrated controller 3 in association with at least a part of the captured image of the imaging unit 13. The communication unit 12 can transmit, for example, the presence or absence and brightness of the person H1 in the facility 500 in the detection result of the detection unit 111 to the control device 21. The communication unit 12 can transmit information on the number of persons in the facility 500 and the measurement result of the temperature sensor 17 in the detection result of the detection unit 111 to the air-conditioning control device 23, for example. The detection result of the detection unit 111 (the presence or absence of the person H1 in the facility 500, the number of people, and the brightness) is information based on the captured image of the imaging unit 13.
(image pickup part)
The imaging unit 13 images a space in the facility 500. More specifically, the imaging unit 13 images, for example, a space in the facility 500 so that the imaging range includes a floor side (for example, a floor surface or a table top) of the facility 500. More specifically, the imaging unit 13 captures an image of a range directly below the imaging unit 13 in a state where the image sensor device 1 is mounted on the ceiling 501. That is, the optical axis of the imaging unit 13 faces downward in the vertical direction.
The imaging unit 13 includes an imaging element 13b, an imaging lens 13a disposed on the front side of the imaging element 13b, a color filter 13c disposed on the imaging element 13b, and a lens holder 13d (see fig. 8) holding the imaging lens 13 a. The image sensor 13b is, for example, a CCD (Charge Coupled device) image sensor or a CMOS (Complementary Metal-oxide semiconductor) image sensor. The image pickup unit 13 picks up a color image, for example.
Therefore, in the image sensor device 1 according to the present embodiment, it is possible to detect the brightness in the facility 500 included in the imaging range 300 based on the image captured by the imaging unit 13.
Here, in the image sensor device 1 according to the present 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 image sensor device 1 according to the present embodiment, 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. The detection range 200 of the detection unit 111 may include at least a part of the imaging range 300 of the imaging unit 13, and may not be the same size as the imaging range 300 of the imaging unit 13.
As shown in fig. 3, the imaging unit 13 is disposed substantially at the center of the circular housing 10 and is provided on a ceiling 501 of the facility 500. The imaging unit 13 may be provided on the ceiling 501 side, for example, may be provided on a framework ceiling.
(Infrared ray receiving part)
The Infrared light receiving unit 14 is, for example, a PIR (Passive Infrared) sensor. The infrared light receiving unit 14 detects infrared light emitted from a human body. The infrared light receiving unit 14 sets a range overlapping at least a part of the imaging range of the imaging unit 13 as a detection range. When the person H1 enters the detection range of the infrared light receiving unit 14 (any of the second regions 205 to 208), the amount of infrared light incident on the infrared light receiving unit 14 changes by an amount corresponding to the temperature difference between the surface of the human body and the background, and the infrared light receiving unit 14 can capture the motion of the person H1.
As shown in fig. 3, the image sensor device 1 according to the present embodiment includes a plurality of (four in fig. 3) infrared light receiving units 14. The plurality of infrared light receiving units 14 are arranged at equal intervals around the imaging unit 13 located at the center of the circular housing 10.
(temperature sensor)
The temperature sensor 17 measures the temperature (room temperature) inside the facility 500. The temperature sensor 17 is constituted by, for example, a thermistor, a thermocouple, or the like. The temperature sensor 17 is disposed in the casing 10, and measures the temperature in the facility 500 by measuring the temperature in an intake port 25, which will be described later, extending from the surface of the casing 10 to the inside.
(Integrated controller)
The integrated controller 3 identifies the plurality of image sensor devices 1 using the unique addresses (identification information) assigned to each of the plurality of image sensor devices 1, respectively. In the present embodiment, the unique addresses (first address and second address) are assigned to each of the plurality of first regions 201 to 204 set for the detection range 200 of the detection unit 111 in each of the image sensor devices 1. Therefore, the integrated controller 3 uses the unique addresses assigned to the first areas 201 to 204 to identify the first areas 201 to 204, respectively. In addition, in the present embodiment, the plurality of control devices 21 are identified using unique addresses assigned to the plurality of control devices 21, respectively.
(appearance of image sensor device)
The image sensor device 1 has the housing 10 as described above. As shown in fig. 5 to 7, the housing 10 includes a housing main body 101 and an exposed portion 102. The case main body 101 and the exposed portion 102 are formed of synthetic resin.
The housing main body 101 is an outer shell that houses components (the imaging unit 13, the infrared light receiving unit 14, the control unit 11, the communication unit 12, and the temperature sensor 17) other than the housing 10 in the image sensor device 1. The casing body 101 is a portion to be fitted into a mounting opening of the ceiling 501. The housing main body 101 is cylindrical (for example, cylindrical). One end (upper end) of the casing main body 101 is closed, and the other end (lower end) of the casing main body 101 is open.
The exposed portion 102 is a portion where the imaging portion 13 and the infrared light receiving portion 14 are provided. The exposed portion 102 is a portion exposed from the ceiling 501 in a state where the image sensor device 1 is mounted on the ceiling 501. The exposed portion 102 is provided at the lower end of the case main body 101 so as to seal the lower end of the case main body 101. The exposed portion 102 is, for example, a disc shape. The diameter of the exposed portion 102 is larger than the diameter of the case main body 101. The outer edge of the exposed portion 102 protrudes toward the outer periphery of the case main body 101 over the entire circumference of the case main body 101 in the circumferential direction. The portion of the exposed portion 102 protruding toward the outer periphery of the case main body 101 is also referred to as a flange portion 102 a.
The exposed portion 102 has a main surface 102 b. The main surface 102b is a main surface on the floor side of the facility 500 in a state where the image sensor device 1 is mounted on the ceiling 501. The main surface 102b is curved toward the outside of the case 10 and protrudes in a dome shape. The thickness of the exposed portion 102 is the thickest at the center of the main surface 102b, and the thickness of the exposed portion 102 decreases along the curvature of the main surface 102b toward the outer peripheral side of the main surface 102 b. The central portion of the main surface 102b may be substantially flat.
The main surface 102b of the exposed portion 102 is provided with an imaging portion 13, a plurality of (e.g., four) infrared light receiving portions 14, an air inlet hole 25, and a display window 26.
The imaging unit 13 is provided in the center of the main surface 102b of the exposed portion 102. More specifically, as shown in fig. 8, a housing recess 102d for housing the imaging unit 13 is provided in the center of the main surface 102 b. The accommodation recess 102d is, for example, a bottomed cylindrical shape and is formed so as to be depressed from the main surface 102 b. The imaging unit 13 is disposed in the housing recess 102d such that the imaging lens 13a projects outward from the opening surface 102e of the housing recess 102d (i.e., such that the imaging lens 13a projects outward from the surface of the housing 10).
The image sensor device 1 has a transparent cover 27. The transparent cover 27 is a member for protecting the imaging unit 13, and is formed of a member having light transmittance (for example, glass or synthetic resin). The transparent cover 27 is disposed on the main surface 102b so as to cover the opening surface 102e of the accommodation recess 102 d. The transparent cover 27 is, for example, dome-shaped, and protrudes from the main surface 102b in a state of being provided on the main surface 102 b. The transparent cover 27 has a shape protruding from the main surface 102b, and thus can protect the imaging unit 13 so as to cover the imaging lens 13a protruding from the housing recess 102 d.
As shown in fig. 8, the optical axis L1 of the imaging unit 13 faces the same direction as the normal L2 at the central portion of the main surface 102b in a state where the imaging unit 13 is provided in the housing 10. A normal line L2 of the main surface 102b is parallel to the central axis L3 of the case main body 101 (see fig. 7). In this way, the optical axis L1 of the imaging unit 13 is directed in the same direction as the normal line L2 of the main surface 102b, and the imaging unit 13 can image a range directly below the imaging unit 13 in a state where the image sensor device 1 is mounted on the ceiling 501.
The plurality of infrared light receiving units 14 are provided around the imaging unit 13 on the main surface 102b of the exposed portion 102. In other words, the plurality of infrared light receiving units 14 are provided on the outer edge side of the main surface 102b (i.e., the outer edge side of the housing 10) with respect to the imaging unit 13 on the main surface 102 b. More specifically, the main surface 102b is provided with a plurality of accommodating recesses 102f for accommodating the plurality of infrared light receiving units 14, respectively. Each of the accommodation recesses 102f is, for example, a bottomed cylindrical shape and is formed so as to be depressed from the main surface 102 b. The inner peripheral surface of each accommodating recess 102f is inclined from one end (the bottom surface of the accommodating recess 102 f) side to the other end (the opening surface of the accommodating recess 102 f) side toward the outer peripheral side, like the outer peripheral surface of a truncated cone. The central axis L5 of the accommodation recess 102f is inclined toward the outer peripheral side (radial direction) with respect to the normal line L2 of the main surface 102b (see fig. 7). Therefore, the opening surface of each accommodation recess 102f is substantially elliptical extending in the radial direction with respect to the normal line L2 of the main surface 102 b.
The infrared light receiving parts 14 are provided on the bottom surfaces of the plurality of accommodating recesses 102f, respectively. The optical axis L6 of the infrared light receiving unit 14 is parallel to the central axis L5 of the accommodating recess 102 f. Accordingly, the infrared receiving unit 14 mainly receives infrared rays from a direction inclined toward the outer peripheral side (normal direction) with respect to the normal line L2 of the main surface 102 b.
The intake hole 25 is, for example, a tubular ventilation path for conveying air in the facility 500 to the location where the temperature sensor 17 is disposed in the casing 10. The shape of the intake port 25 is not limited to a pipe shape, and may be any shape as long as it can convey the air in the facility 500 to the installation position of the temperature sensor 17 in the casing 10. The intake holes 25 extend from the main surface 102b of the housing 10 toward the inside of the housing 10. The intake port 25 has an intake port 25a (see fig. 6) and an exhaust port 25b (see fig. 7) on the surface of the housing 10. The intake port 25 is disposed in the housing 10, and is formed to communicate the intake port 25a with the exhaust port 25 b. That is, the intake port 25a is open at one end of the intake port 25, and the exhaust port 25b is open at the other end of the intake port 25.
Air inlet 25a is provided between infrared light receiving sections 14 on main surface 102 b. More specifically, air inlet 25a is provided between adjacent infrared light receiving sections 14 in the circumferential direction of main surface 102 b. The air inlet 25a is formed of, for example, two slits 25c, and extends in the radial direction of the main surface 102 b. The number of slits 25c is not limited to two. In addition, the shape of the intake port 25a may be rectangular or circular, instead of slit-shaped. The exhaust port 25b is provided in the outer peripheral surface 101a (side surface) of the casing main body 101. In more detail, the exhaust port 25b may be provided at the bottom surface 101b of the case main body 101.
As described above, the intake hole 25 has the intake port 25a and the exhaust port 25b, whereby the air in the intake hole 25 is exhausted from the exhaust port 25b, and the air in the facility 500 efficiently flows into the intake port 25 a. Since the air in the facility 500 efficiently flows into the air intake hole 25, the temperature (room temperature) in the facility 500 is reflected by the temperature in the air intake hole 25. Thus, even if the temperature sensor 17 is disposed in the casing 10, the temperature in the facility 500 can be effectively measured by measuring the temperature of the air flowing into the intake port 25. In the present embodiment, the image sensor device 1 is provided by a return chamber in ceiling (return chamber) air conditioning system (a system in which indoor air is discharged to the ceiling), for example.
The temperature sensor 17 is provided in the intake port 25 (fig. 7) in a state of being accommodated in the housing 10, and measures the temperature of the space inside the intake port 25. That is, the temperature sensor 17 measures the temperature of the space inside the intake port 25 (in other words, the temperature of the air flowing into the housing 10 through the intake port 25), thereby measuring the temperature inside the facility 500.
The air inlet 25a is provided in the main surface 102b of the exposed portion 102, so that air in the facility 500 can be efficiently taken into the air inlet 25 a. Further, since the exhaust port 25b is provided on the outer peripheral surface 101a of the casing body 101 and the casing body 101 is provided on the back side of the ceiling 501, the air flowing into the intake port 25 can be efficiently exhausted to the back side of the ceiling 501. This can prevent air discharged from the exhaust port 25b from being again taken in from the intake port 25 a.
The display window 26 is a window that exposes the light emitting section 28. The light emitting unit 28 notifies the operating state of the image sensor device 1 of the light emitting state. The light emitting unit 28 is, for example, an LED (light emitting diode). In the present embodiment, a plurality of display windows 26 (two in the example of fig. 6) are provided, but only one display window may be provided. The two display windows 26 are disposed around the imaging unit 13 on the main surface 102 b. More specifically, the two display windows 26 are disposed between the image pickup unit 13 and the air inlet 25a, for example.
The image sensor device 1 includes a plurality of light emitting portions 28 corresponding to the plurality of display windows 26 one for one. A corresponding light emitting unit 28 is disposed behind the display window 26. The plurality of light emitting portions 28 are exposed to the outside through the corresponding display windows 26. The plurality of light emitting units 28 display whether or not they are operating in a lit state (on or off). Further, the plurality of light emitting sections 28 may emit different colors (red or green) or change the lighting state (lighting or blinking) depending on whether or not the image sensor device 1 detects a person, thereby displaying whether or not the image sensor device 1 is detecting a person.
The image sensor device 1 is attached to the ceiling 501 such that the housing main body 101 is fitted into the attachment opening of the ceiling 501 and the exposed portion 102 closes the attachment opening. For example, the housing 10 is mounted on the ceiling 501 by fixing the exposed portion 102 to the peripheral edge of the mounting opening. In this state, the exposed portion 102 is exposed to the inside of the facility 500 (see fig. 5), and the casing main body 101 is exposed to the rear side of the ceiling 501 (see fig. 7). Thereby, the air inlet 25a is exposed to the inside of the facility 500, and the air outlet 25b is exposed to the rear side of the ceiling 501. The optical axis L1 of the imaging unit 13 faces downward in the vertical direction. This enables the imaging unit 13 to capture an area directly below the imaging unit 13.
(communication action)
The communication operation of the integrated controller 3 with the image sensor device 1, the control device 21, and the air conditioning control device 23 will be described.
The integrated controller 3 performs polling between the control device 21 and the image sensor apparatus 1 until an interrupt signal from the image sensor apparatus 1 is detected. The "interrupt signal" described in the present disclosure is a signal sent from the image sensor device 1 that detects the monitoring input to the integrated controller 3 via the signal line 4 when at least one image sensor device 1 of the plurality of image sensor devices 1 detects the monitoring input.
In the present embodiment, the monitoring input is a human detection input, a human number detection input, a brightness detection input, and a temperature measurement input. The person detection input is an input generated when the presence of the person H1 in the facility 500 (movement or stay) is detected by the first person detection function of the detection unit 111. The number-of-persons detection input is an input that notifies the number of persons in the facility 500 when the number of persons detected by the second detection function of the detection section 111 changes. The brightness detection input is an input for notifying the brightness (illuminance on the floor 502) detected by the brightness detection function when the brightness in the facility 500 changes abruptly. The temperature measurement input is an input (temperature measurement input) that notifies the temperature when the temperature within the facility 500 measured by the temperature sensor 17 changes.
The integrated controller 3 periodically transmits a transmission signal including sequentially changed addresses to the plurality of control devices 21 and the plurality of image sensor apparatuses 1 via the signal line 4 in polling. Each of the plurality of control devices 21 acquires the control data included in the transmission signal when the address included in the transmission signal matches its own address. Further, the plurality of control devices 21 respectively return the control states of the corresponding lighting fixtures 22 to the integrated controller 3 as monitoring data. Each of the plurality of image sensor devices 1 acquires the control data included in the transmission signal when the address included in the transmission signal from the integrated controller 3 matches any one of the plurality of first regions 201 to 204 included in the detection range 200 of the detection unit 111. The plurality of image sensor devices 1 also respectively return the detection results of the detection units 111 in the corresponding first areas among the plurality of first areas 201 to 204 to the integrated controller 3 as the monitoring data.
If an interrupt signal from the image sensor device 1 is detected, the integrated controller 3 executes the interrupt processing. In the interrupt processing, the integrated controller 3 transmits an inquiry signal for inquiring the image sensor device 1, which is a generation source of the interrupt signal, to the signal line 4. When the image sensor device 1, which is the source of the interrupt signal, receives the inquiry signal, the generation of the interrupt signal is stopped, and the address thereof is returned to the integrated controller 3.
If there is a reply from the image sensor device 1 that is the generation source of the interrupt signal, the integrated controller 3 acquires the address of the image sensor device 1 that is the generation source of the interrupt signal to determine the image sensor device 1 that is the generation source of the interrupt signal. Then, the integrated controller 3 specifies the address of the image sensor apparatus 1 that is the generation source of the interrupt signal, and transmits a transmission signal (hereinafter referred to as "reply request signal") including reply request data requesting reply monitoring input.
When acquiring the reply request data including the address of the image sensor apparatus 1, which is the source of the interrupt signal, the image sensor apparatus replies to the monitoring input in response thereto.
The interrupt processing is completed if the integrated controller 3 acquires a monitor input from the image sensor device 1 as a generation source of the interrupt signal. Then, the integrated controller 3 transmits a transmission signal (hereinafter, referred to as "control signal") containing control data to the control device 21 corresponding to the address contained in the monitoring input. Thereby, the control device 21 that has received the control signal controls the lighting fixture 22 according to the control data contained in the received control signal. In addition, the integrated controller 3 controls the air conditioning control device 23 using the communication line 5 other than the communication line 4 according to the content of the monitoring input from the image sensor device 1 that is the generation source of the interrupt signal. After that, the integrated controller 3 performs polling until an interrupt signal is generated again in the signal line 4.
Further, in the present embodiment, when the monitoring input generated in the image sensor device 1 is a human detection input or a brightness detection input, the control device 21 is controlled by the integrated controller 3, and the control device 21, for example, lights the illumination device 22 or controls dimming of the illumination device 22. In addition, when the monitoring input generated in the image sensor device 1 is a temperature measurement input, the air conditioning control device 23 is controlled by the integrated controller 21, and the air conditioning control device 23 controls, for example, the air conditioning temperature of the air conditioning device 24. In particular, when the monitoring input generated in the image sensor device 1 is a human number detection input, the air conditioning control device 23 is controlled by the integrated controller 21, and the air conditioning control device 23 rapidly changes the air conditioning temperature of the air conditioning device 24, for example. This enables the temperature in the facility 500 to be quickly lowered when, for example, the number of people in the facility 500 increases rapidly. That is, for example, when many people gather in the facility 50 when cooling air in summer, it takes time for the space temperature to rise due to heat generation of the people and the temperature sensor 17 to capture the change and perform air conditioning control. Therefore, when the number of people is measured by the image sensor device 1 and the number of people is greatly increased, the set temperature is lowered in an auxiliary manner, and air conditioning control can be performed in the facility 500 without giving a sense of discomfort.
(Effect)
As described above, the image sensor device 1 according to the present embodiment includes the temperature sensor 17 that measures the temperature in the facility 500, in addition to the imaging unit 13 that images the inside of the facility 500. Therefore, the image sensor device 1 can photograph the inside of the facility 500, and can also measure the temperature of the inside of the facility 500.

In the above-described embodiment, the intake port 25a of the intake hole 25 is provided on the main surface 102b of the exposed portion 102 (see fig. 5 to 7). However, in the present modification, as shown in fig. 9 to 11, the intake port 25a of the intake port 25 is provided on the outer peripheral surface 102i (side surface) of the exposed portion 102. More specifically, the thickness of the exposed portion 102 of the present modification is, for example, greater than that of the exposed portion 102 of embodiment 1. Further, a groove portion 102j is provided on an outer peripheral surface 102i of the exposed portion 102 in the present embodiment. The groove 102j is provided at the center in the width direction (vertical direction) of the outer peripheral surface 102i of the exposed portion 102 over the entire circumference of the exposed portion 102 in the circumferential direction.

Further, since the groove portion 102j is provided on the outer peripheral surface 102i of the exposed portion 102 and the intake port 25a is provided on the bottom surface of the groove portion 102j, the intake port 25a can be further suppressed from being conspicuous when viewed from the floor surface side.

When the main surface 102b is formed to be flat while keeping the shape of the main surface 102b in a circular shape, the opening surface of the accommodating recess 102f is enlarged in order to secure the depth of the accommodating recess 102 f. In order to include the opening surfaces of the four housing recesses 102f in the main surface 102b, the main surface 102b needs to be a circular shape having a larger area. In the present modification, by forming the main surface 102b in a square shape, even if the opening surfaces of the four housing recesses 102f are included in the main surface 102b, the area of the main surface 102b can be further reduced.
According to the present modification, since the main surface 102b of the exposed portion 102 is a flat surface, the housing 10 can be prevented from being conspicuous when the housing 10 is mounted on the ceiling 501.

The intake port 25a is provided in the bottom surface of the groove portion 102 j.
According to the present modification, since the air inlet 25a is provided on the outer peripheral surface 102i of the exposed portion 102, the air inlet 25a can be prevented from being conspicuous when viewed from the floor side in a state where the image sensor device 1 is mounted on the ceiling 501. Further, since the groove portion 102j is provided on the outer peripheral surface 102i of the exposed portion 102 and the air inlet 25a is provided on the bottom surface of the groove portion 102j, the air inlet 25a can be further suppressed from being conspicuous when viewed from the floor surface side.
