In other words, the identification information set for each of the plurality of first areas 201 to 204 is set for each of the plurality of detection targets 400 for each of the plurality of first areas 201 to 204.

Here, in the detection system 1 according to this embodiment, the identification information setting section 151 has a setting mode. In the setting mode, by setting identification information for a specific area that is one of the plurality of first areas 201 to 204, identification information is automatically set for other areas other than the specific area. mode. For example, if 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 can set the identification information in other areas other than the specific area. Identification information is set for certain first areas 202-204. 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 an address of "2" for the remaining first areas 202 to 204. ”, “3”, and “4” addresses, respectively. Note that 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 according to the present embodiment, the identification information setting unit 151 sets identification information (address) for the specific area (first area 201) based on input from the outside (remote controller 6). Therefore, it has a setting mode for setting identification information for other areas (first areas 202 to 204). Thereby, by simply setting identification information for a specific area, identification information can be set for all areas (specific area and other areas). As a result, the time required to set identification information for the first areas 201 to 204 can be reduced.

The detection range setting section 152 is configured to set the detection range 200 of the detection section 111 with respect to the imaging range 300 of the imaging section 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) that constitutes the imaging range 300. The unit area 301 is, for example, an area composed of a plurality of pixels, but may be set on a pixel-by-pixel basis. In this embodiment, the detection range setting unit 152 is set to detect the detection target 400 in all unit areas 301, and as a result, the detection range 200 of the detection unit 111 is set to It is set to the same size as the range 300 (see FIG. 4).

The area setting section 153 can set a plurality of first areas 201 to 204 in the detection range 200 of the detection section 111. Further, the area setting unit 153 can change the number of divisions of the plurality of first areas 201 to 204. As a result, for the detection range 200 of the detection unit 111, one first area 201, two first areas 201 and 202, or four first areas 201 to 204 can be set. can do. Further, as shown in FIG. 4, the area setting section 153 sets a plurality of first areas 201 to 204 with a smaller size than the plurality of second areas 205 to 208, which are the detection ranges of the plurality of infrared receiving sections 14. can do. Note that the area setting of the detection range 200 will be explained in detail in the section "(3) Area setting".

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

Further, the function setting section 154 is configured to limit functions according to height information input using the remote controller 6. For example, in the case of the first person detection function, the function setting unit 154 disables the first person detection function if the above-mentioned height dimension is 4.6 m or more, and sets the detection result of the detection unit 111 to “presence”. ”. In the case of the second person detection function, the function setting unit 154 disables the second person detection function and disables the output of the detection result of the detection unit 111 if the height dimension is less than 2.8 m. make it stop.

Here, the detection system 1 according to this embodiment has both the imaging section 13 and the infrared light receiving section 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. have. Therefore, the function setting section 154 is preferably configured to enable/disable at least one of the first function and the second function according to the height information. Thereby, it is possible to set validity/invalidity for at least one of the first function and the second function. In this embodiment, the function setting unit 154 can enable/disable both the first function and the second function.

Further, as in the present embodiment, when detecting the detection target 400 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, the imaging unit It is preferable that the combinations of the sensor 13 and other sensors differ depending on the height information. For example, if the above-mentioned height dimension is 4.5 m or less, the infrared light receiving section 14 functions normally, so the detection target 400 (person H1) is detected based on the outputs of the imaging section 13 and the infrared light receiving section 14. do. On the other hand, if the height dimension is 4.6 m or more, the infrared light receiving section 14 may not function properly, so the detection target 400 is detected based on the output of the imaging section 13 alone. In this way, by changing the combination of the imaging unit 13 and other sensors 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. .

Furthermore, it is preferable that the height information is also used for settings related to the imaging section 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 making settings regarding the imaging section 13.

The information setting unit 155 is configured to set output information based on the detection results of the detection unit 111 for each of the plurality of functions. In the detection system 1 according to this embodiment, the detection unit 111 has a person detection function and a brightness detection function. In other words, the detection unit 111 has multiple functions. Therefore, the information setting unit 155 sets output information for the human detection function and also sets output information for the brightness detection function. For example, for the first person detection function among the person detection functions, if the height dimension is 4.6 m or more, the information setting unit 155 sets information indicating "presence" or "absence" in the output information. . Further, for example, for the first person 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 as output information. In this way, the information setting unit 155 can set output information for each of a plurality of functions.

(2.2.6) Storage unit The storage unit 16 is configured of a device selected from, for example, ROM (Read Only Memory), RAM (Random Access Memory), or EEPROM (Electrically Erasable Programmable Read Only Memory). .

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

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

Each of the first areas 201 and 204 is an area including a total of 12 unit areas 301 with 3 rows and 4 columns. Each of the first areas 202 and 203 is an area including a total of 20 unit areas 301 with 5 rows and 4 columns.

For example, when one lighting fixture 22 is associated with the detection range 200 of the detection unit 111, one first area 201 is set. Further, when four lighting fixtures 22 are associated with the detection range 200 of the detection unit 111, four first areas 201 to 204 are set. Thereby, a plurality of first areas 201 to 204 can be set depending on the output destination or purpose of the detection result of the detection unit 111.

Furthermore, the area setting unit 153 may be able to set different areas for use in detecting the person H1 and for use in detecting the surrounding environment.

(4) Operation Next, the operation of the detection system 1 according to this embodiment will be explained.

(4.1) Setting operation First, the setting operation of the detection system 1 according to the present embodiment will be explained with reference to FIG. 6.

The builder uses the remote control 6 to input settings for setting the detection range 200 (step S1). After that, the builder uses the remote controller 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 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 input settings for setting the first areas 201 to 204 (step S5). After that, the builder 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 to 204 based on 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 addresses (first address and second address) to be assigned to each of the first areas 201 to 204 (step S9). After that, the builder uses the remote control 6 to transmit 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 input information from the remote controller 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 to 204 (step S12).

Furthermore, the builder uses the remote controller 6 to input height information regarding the height at which the detection system 1 (imaging unit 13) is installed (step S13). In this embodiment, it is possible to input height information for each function that the detection unit 111 has, and it is possible to input height information for each of the first person detection function, second person detection function, and brightness detection function. can. After that, the builder uses the remote controller 6 to transmit 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 input information from the remote controller 6 (step S15). The function setting unit 154 sets, for example, enable/disable of the first person detection function, the second person detection function, and the brightness detection function. Further, when the first person detection function is set to be disabled, the function setting unit 154 sets the “presence” information to be output as the detection information from the detection unit 111. Further, when the second person detection function is set to be disabled, the function setting unit 154 sets the detection information from the detection unit 111 not to be output. Then, the control unit 11 causes the storage unit 16 to store the contents set by the function setting unit 154 (step S16).

Note that the order in which the detection range, area, and address are set is just an example. For example, you may set the area, then the detection range, and then the address, or you may set the area, then the address, and then the detection range. May be set. The order in which height information is input is also an example; for example, it may be done before setting the detection range, before setting the area, or before setting the address. Good too.

(4.2) Communication Operation Furthermore, the communication operation between the transmission unit 3, the detection system 1, and the control terminal 21 will be explained.

The transmission unit 3 performs polling until it detects an interrupt signal. The "interrupt signal" in the present disclosure is a current mode generated in the signal line 4 by the detection system 1 that has detected the monitoring input when at least one detection system 1 among the plurality of detection systems 1 detects the monitoring input. It's a signal. In addition, the “current mode signal” in the present disclosure is expressed by a current change caused by switching between a state in which the signal lines 4 are open and a state in which a low impedance element is connected between the signal lines 4. This is a signal that

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

During polling, the transmission unit 3 periodically transmits a transmission signal containing a sequentially changed address to the signal line 4. Each of the plurality of control terminals 21 acquires the control data included in the transmission signal when the address included in the transmission signal matches its own address. Each of the plurality of control terminals 21 then returns the control state of the corresponding lighting fixture 22 as monitoring data. In the present disclosure, "reply" refers to transmitting data to the transmission unit 3 using a current mode signal synchronized with a period defined as a reply band among the transmission signals transmitted from the transmission unit 3. .

Further, each of the plurality of detection systems 1 detects the transmission signal when the address included in the transmission signal matches any one of the plurality of first areas 201 to 204 included in the detection range 200 of the detection unit 111. Get the included control data. Then, each of the plurality of detection systems 1 returns the detection results of the detection unit 111 in the corresponding first area among the plurality of first areas 201 to 204 as monitoring data.

When the transmission unit 3 detects the interrupt signal, it executes the interrupt process. In interrupt processing, the transmission unit 3 transmits an interrogation signal to the signal line 4 to inquire about the detection system 1 that is the source of the interrupt signal. When the detection system 1 that is the source of the interrupt signal receives the interrogation signal, it stops generating the interrupt signal and returns its own address.

If the transmission unit 3 receives a reply from the detection system 1 that is the source of the interrupt signal, it 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 "reply request signal").

When the detection system 1 that is the source of the interrupt signal obtains the reply request data including its own address, it replies with the monitoring data in response.

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. The transmission unit 3 then transmits a transmission signal containing control data (hereinafter referred to as a "control signal") to the control terminal 21 corresponding to the address included in the monitoring data. Thereby, the control terminal 21 that has received the control signal controls the lighting fixture 22 by controlling the relay according to the control data included in the received control signal. Thereafter, the transmission unit 3 performs polling until an interrupt signal is generated on the signal line 4 again.

(5) Effects As described above, the detection system 1 and the device control system 100 according to the present embodiment include the function setting unit 154 that sets the function of the detection unit 111 according to height information. Therefore, for example, by inputting height information into the detection system 1 using the remote control 6, the function of the detection unit 111 can be set according to the height at which the imaging unit 13 is installed.

Further, when the imaging unit 13 and the infrared light receiving unit 14 are used together as in the detection system 1 according to the present embodiment, the presence or absence of the person H1 can be detected even when the inside of the facility 500 is dark.

(6) Examples (6.1) Use of air conditioning control Air conditioning control in the office is mainly performed by measuring the temperature, humidity, and CO ₂ concentration of the office space and performing feedback control to approach target values. However, due to the increasing number of office buildings without pillars, the locations where sensors can be installed may be limited, and if the temperature sensor is installed on a wall, etc., changes in temperature at a location away from the sensor will not be immediately reflected in the measured value. This becomes an issue. Therefore, it is necessary to measure the number of people, which is a factor that affects increases and decreases in temperature and CO ₂ concentration, and to control the air conditioning temperature and outside air intake before changes in the temperature sensor and CO ₂ concentration sensor (feedforward control). It has the potential to provide air conditioning control with an emphasis on comfort. For example, when many people gather in a certain area, such as a conference room, during air conditioning in the summer, the temperature of the space rises due to the heat generated by the people, but it may take time for a temperature sensor to detect this change and control the air conditioning. Therefore, it would be possible to measure the number of people using an image sensor, and if there is a significant increase in the number of people, by lowering the set temperature as an auxiliary measure, it would be possible to control the air conditioning without causing discomfort to the workers.

(6.2) Visualization of office usage status In recent years, with increasing interest in work style reform, various improvement measures are being considered for offices, but changes in work styles before and after improvements can be assessed through surveys and interviews. is often investigated by visual observation. However, since the results of questionnaires are subjective and continuous human observation is difficult, there is a need for objective and continuous visualization of office usage through sensing. For example, if the usage status of a meeting space is measured using the image sensor's number of people level (including classification of number of people or number of people into multiple categories) measurement function, the usage status of a meeting space can be measured by the presence or absence of an event and the time of the meeting. It is possible to understand the relative usage status of the space.
