Here, in the detection system 1 of this embodiment, the identification information setting unit 151 has a setting mode. The setting mode is a mode in which identification information is set for one of the plurality of first areas 201 to 204, that is, a specific area, and identification information is automatically set for other areas except the specific area. For example, when the first area 201 among the plurality of 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 the other areas except the specific area, that is, the first area. Areas 202~204 set identification information. Specifically, in the setting mode, the identification information setting unit 151 sets the address of "1" for the first area 201, for example, and sets "2", "3", and "2" for the remaining first areas 202 to 204 respectively. 4" address. In addition, the address setting for the first area 201 can be performed using the remote control (setting device) 6 . That is, in the detection system 1 of this embodiment, the identification information setting unit 151 sets identification information (address) for a specific area (first area 201) based on input from the outside (remote controller 6), and Set the setting mode of the identification information for other areas (first areas 202 to 204). Thereby, identification information can be set only for a specific area, and identification information can be set for all areas (specific areas and other areas). As a result, the time required to set the identification information for the first areas 201 to 204 can be shortened.

The detection range setting unit 152 is configured to set the detection range 200 of the detection unit 111 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 of the unit areas 301 (see FIG. 4 ) constituting the imaging range 300 . The unit area 301 is, for example, an area composed of a plurality of pixels, but may be set in units of pixels. In this embodiment, the detection range setting unit 152 sets the detection target 400 to be detected in all unit areas 301. As a result, the detection range 200 of the detection unit 111 is set to be the same as that of the imaging unit 13. The imaging range 300 has the same size (see FIG. 4 ).

The area setting unit 153 can set a plurality of detection ranges 200 of the detection unit 111. Area 1 201~204. In addition, the area setting unit 153 can change the number of divisions of the plurality of first areas 201 to 204. Thereby, one first area 201, two first areas 201 and 202, or four first areas 201 to 204 can be set for the detection range 200 of the detection unit 111. In addition, as shown in FIG. 4 , the area setting unit 153 can set the plurality of first areas 201 to 204 to be smaller than the detection ranges of the plurality of infrared light receiving units 14 , that is, the plurality of second areas 205 to 208 . In addition, the area setting of the detection range 200 is explained in detail in the column of "(3) Area Setting".

The function setting unit 154 is configured to set the function of the detection unit 111 based on the height information input using the remote controller 6 . That is, the function setting unit 154 obtains height information based on input from the outside (for example, the remote control 6 ). The height information is information about the installation height of the imaging device including the imaging unit 13 . 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 the first person detection function that detects whether the person H1 exists within the detection range 200 in the person detection function, as long as the above-mentioned height dimension is 2.4m or more and 4.5m or less, the function setting unit 154 Enable the first person detection function. Also, in the case of the second person detection function that detects the number of people H1 present in the detection range 200 in the person detection function, as long as the above-mentioned height dimension is 2.8m or more and 8.0m or less, the function is set Part 154 enables the second person detection function. In addition, in the case of the brightness detection function, as long as the height dimension is 2.4 m or more and 8.0 m or less, the function setting unit 154 sets the brightness detection function to be valid. In this way, the function setting unit 154 can set the function of the detection unit 111 based on the above-mentioned height information.

In addition, the function setting unit 154 is configured to limit functions based on height information input using the remote controller 6 . For example, in the case of the first person detecting function, if the height dimension is 4.6 m or more, the function setting unit 154 disables the first person detecting function and fixes the detection result of the detecting unit 111 to "exist". Also, when the second person detects the function, if the above If the height dimension is less than 2.8m, the function setting unit 154 disables the second person detection function and stops the output of the detection result by the detection unit 111 .

Here, the detection system 1 of this embodiment has both the imaging part 13 and the infrared light receiving part 14 as mentioned above. That is, the detection unit 111 has the first function of detecting the detection object 400 based on the image captured by the imaging unit 13 and the second function of detecting the detection object 400 based on the infrared ray received by the infrared light receiving unit 14 . Object 400 performs detection. Therefore, the function setting unit 154 is preferably configured to set the validity/invalidity of at least one of the first function and the second function based on the above-mentioned height information. Thereby, it is possible to set the validity/invalidity of at least one of the first function and the second function. In this embodiment, the function setting unit 154 can set the validity/invalidity of both the first function and the second function.

In addition, as in this embodiment, when the detection object 400 is detected based on the image captured by the imaging unit 13 and the output of another sensor (infrared light receiving unit 14) different from the imaging unit 13, it is easier to It is preferable to use the above-mentioned height information to make the combination of the camera unit 13 and other sensors different. For example, when the height dimension is 4.5 m or less, since the infrared light receiving unit 14 functions normally, the detection object 400 (person H1) is detected based on the outputs of the imaging unit 13 and the infrared light receiving unit 14. On the other hand, when the height dimension is 4.6 m or more, since the infrared light receiving unit 14 may not function properly, the detection target 400 is detected based only on the output of the imaging unit 13 . In this way, by changing the combination of the imaging unit 13 and other sensors according to the installation height of the imaging unit 13, the detection object 400 (person H1) can be detected regardless of the height.

Furthermore, it is preferable that the above-mentioned height information is also used for setting the imaging unit 13 . For example, regarding the imaging unit 13, the focal distance to the detection object 400 can be set by inputting the above-mentioned height information. Thereby, there is an advantage that it is not necessary to input the height information for setting the camera unit 13. point.

The information setting unit 155 is configured to set output information based on the detection result of the detection unit 111 for each of a plurality of functions. In the detection system 1 of this embodiment, the detection unit 111 has a human detection function and a brightness detection function. That is, the detection unit 111 has a plurality of functions. Therefore, the information setting unit 155 sets the output information for the human detection function and sets the output information for the brightness detection function. For example, regarding the first person detection function among the person detection functions, as long as the above-mentioned height dimension is 4.6m or more, the information setting unit 155 will set information indicating "presence" or "absence" as output information. For example, regarding the first person detection function, as long as 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 as output information. In this way, the information setting unit 155 can set output information for a plurality of respective functions.

Furthermore, the storage unit 16 stores the identification information (the first address and the second address) set by the identification information setting unit 151. Furthermore, the memory unit 16 stores the height information of the detection system 1 input using the remote controller 6 . Furthermore, the memory unit 16 stores the validity/invalidity of the human detection function, the validity/invalidity of the brightness detection function, the validity/invalidity of the first function, and the validity/invalidity of the second function. Furthermore, the storage unit 16 associates and stores the output information set by the information setting unit 155 with each function.

(4)Action

Next, the operation of the detection system 1 of this embodiment will be described.

(4.1) Set action

First, the setting operation of the detection system 1 of this embodiment will be described with reference to FIG. 6 .

The constructor uses the remote controller 6 to perform setting input for setting the detection range 200 (step S1). Thereafter, the constructor uses the remote controller 6 to send 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 controller 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 causes the storage unit 16 to store the detection range 200 set by the detection range setting unit 152 (step S4).

Furthermore, the builder uses the remote controller 6 to perform setting input for setting the first areas 201 to 204 (step S5). Thereafter, the constructor uses the remote controller 6 to send 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 to 204 based on the input information from the remote controller 6 (step S7). Then, the control unit 11 causes the storage unit 16 to store the first areas 201 to 204 set by the area setting unit 153 (step S8).

Furthermore, the builder uses the remote controller 6 to input the addresses (the first address and the second address) assigned to each of the first areas 201 to 204 (step S9). Thereafter, the constructor uses the remote controller 6 to send the input information to the detection system 1 (step S10). In the detection system 1, the identification information setting unit 151 sets an address (identification information) for each of the first areas 201 to 204 based on the input information from the remote controller 6 (step S11). Then, the control unit 11 associates the addresses set by the identification information setting unit 151 with the first areas 201 to 204 and causes the memory unit 16 to store them (step S12).

Furthermore, the constructor uses the remote controller 6 to input information about the detection system 1 (camera unit 13) Set the height information of the height (step S13). In this embodiment, height information can be input to each function of the detection unit 111, and height information can be input to each of the first person detection function, the second person detection function, and the brightness detection function. Thereafter, the constructor uses the remote controller 6 to send the input information to the detection system 1 (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 controller 6 (step S15). The function setting unit 154 sets, for example, the validity/invalidity of the first person detection function, the second person detection function, and the brightness detection function. Furthermore, when the first person detection function is set to be disabled, the function setting unit 154 outputs "present" information as the detection information from the detection unit 111 . Furthermore, when the function setting unit 154 sets the second person detection function to be disabled, the detection information from the detection unit 111 is not output. Then, the control unit 11 causes the storage unit 16 to store the content set by the function setting unit 154 (step S16).

In addition, the order of setting the detection range, area and address is just an example. For example, the detection range and address can be set in sequence after setting the area, and the address and detection range can be set in sequence after setting the area. In addition, the order of inputting height information is also an example. For example, it may be performed before setting the detection range, before setting the area, or before setting the address.

(4.2) Communication actions

Furthermore, the communication operation between the transmission unit 3, the detection system 1, and the control terminal 21 will be described.

The transmission unit 3 performs polling until an interrupt signal is detected. The "interrupt signal" mentioned in this disclosure means that when at least one of the plurality of detection systems 1 detects a monitoring input, the detection system 1 that detects the monitoring input causes the signal line 4 to generate The current mode signal. In addition, the "current mode signal" mentioned in this disclosure is a signal represented by a change in current generated by switching the state between the lines of the signal line 4 and the state of connecting a low-impedance element between the lines of the signal line 4 .

In this embodiment, the monitoring input is an input generated when the first person detection function detects the presence of person H1 in the facility 500, and the brightness detection function detects the brightness in the facility 500 ( Input generated when the illumination of the ground 502 changes rapidly. In addition, when a plurality of monitoring inputs occur simultaneously, the transmission unit 3 is configured to obtain the monitoring inputs sequentially from a smaller address, for example.

During polling, the transmission unit 3 periodically sends transmission signals containing sequentially changed addresses to the signal line 4 . Each of the plurality of control terminals 21 obtains the control data contained in the transmission signal when the address contained in the transmission signal is consistent with its own address. Furthermore, each of the plurality of control terminals 21 returns the control status of the corresponding lighting fixture 22 as monitoring data. "Reply" as used in this disclosure means sending data to the transmission unit 3 through the current mode signal in the transmission signal sent from the transmission unit 3 that is synchronized with the period designated as the reply frequency band.

Furthermore, when the address included in the transmission signal of each of the plurality of detection systems 1 matches the address of any one of the plurality of first areas 201 to 204 included in the detection range 200 of the detection unit 111, Obtain the control data contained in the transmission signal. Furthermore, each of the plurality of detection systems 1 returns the detection results of the detection units 111 of the corresponding first areas among the plurality of first areas 201 to 204 as monitoring data.

When detecting the interrupt signal, the transmission unit 3 performs interrupt processing. During interrupt processing, the transmission unit 3 sends a query signal to the signal line 4 to inquire about the detection system 1 of the source of the interrupt signal. Moreover, when receiving the challenge signal, the detection system 1 of the source of the interrupt signal stops generating the interrupt signal and returns its own address.

If the transmission unit 3 receives a reply from the detection system 1 of the source of the interrupt signal, it obtains the address of the detection system 1 of the source of the interrupt signal and specifies the detection system 1 of the source of the interrupt signal. Furthermore, the transmission unit 3 specifies the bit of the detection system 1 of the source of the interrupt signal. address and send a transmission signal containing reply request data (hereinafter referred to as the "reply request signal").

When the detection system 1 of the source of the interrupt signal obtains the reply request data including its own address, it responds to it and replies with the monitoring data.

The transmission unit 3 completes the interrupt processing when acquiring the monitoring data from the detection system 1 that generates the interrupt signal. Furthermore, the transmission unit 3 transmits a transmission signal including the control data (hereinafter referred to as "control signal") to the control terminal 21 corresponding to the address included in the monitoring data. Thereby, the control terminal 21 that receives the control signal controls the relay according to the control data contained in the received control signal, thereby controlling the lighting fixture 22 . Thereafter, the transmission unit 3 performs polling until an interrupt signal is generated on the signal line 4 again.

(5)Effect

In the detection system 1 and the machine control system 100 of this embodiment, the detection object 400 can be detected in each of the plurality of first areas 201 to 204. Furthermore, in the detection system 1 and the machine control system 100 of this embodiment, identification information is set for each of the plurality of first areas 201 to 204. Therefore, the detection results of the detection unit 111 can be output to each of the plurality of first areas 201 to 204 in a state where the detection results of the detection unit 111 are distinguished for each of the plurality of first areas 201 to 204. That is, according to the detection system 1 and the machine control system 100 of this embodiment, the detection results of the detection part 111 can be output to each of the plurality of first areas 201 to 204 set for the detection range 200 of the detection part 111 .

Furthermore, like the detection system 1 of this embodiment, when the imaging unit 13 and the infrared light receiving unit 14 are used together, the presence or absence of H1 can be detected even in a dark situation in the facility 500 .

(6) Example

(6.1) Air conditioning control utilization

The air-conditioning control in the office mainly measures the temperature, humidity, and CO ₂ concentration of the work space and performs feedback control in a manner close to the target value. However, due to the increase in column-free office buildings, there are cases where the installation location of the sensor is limited. When the temperature sensor is installed on a wall, etc., the temperature change in a place far away from the sensor is not immediately reflected in the measurement. value becomes an issue. Therefore, the factor that affects the increase or decrease in temperature or CO ₂ concentration is measured, that is, the number of people, and the temperature control or atmospheric introduction control of the air conditioner is controlled before the changes in the temperature sensor or CO ₂ concentration sensor (feedforward control ), thereby providing the possibility of providing air-conditioning control that emphasizes comfort. For example, during summer cooling, when many people gather in certain areas such as conference rooms, the space temperature may rise due to heat dissipation from people, but it takes time for the temperature sensor to capture this change and perform air conditioning control. Therefore, image sensors are used to measure the number of people. If the number of people increases significantly, the set temperature is auxiliarily lowered. It is believed that this can be used to control the air conditioning without causing discomfort to the staff.

(6.2) Visualization of office utilization

In recent years, due to increased attention to work style reform, various office improvement measures are being studied. However, changes in work style before and after improvement are mostly investigated through questionnaires or visual observations. However, since questionnaires are subjective results and it is difficult to carry out continuous surveys through human observation, it is expected to use sensing to visualize objective and continuous office utilization. For example, when using the image sensor's measurement function of the number of people (including the number of people or classifying the number of people into multiple categories) to measure the utilization of the discussion space, the presence/absence of the event can be relatively grasped. Utilization of discussion space during the time period.
