In addition, in the detection system 1 of the present embodiment, the detection result of the detection unit 111 includes person information about the person. In the present embodiment, the person information includes the presence/absence information indicating whether the person H1 exists in the detection range 200, and the number information indicating the number of persons H1 in the detection range 200. Furthermore, in the detection system 1 of this embodiment, the detection result of the detection unit 111 includes information about the surrounding environment. In this embodiment, the information about the surrounding environment is the brightness information in the facility 500, specifically, the information about the illuminance of the ground 502 of the facility 500.

In addition, the detection unit 111 can detect the person H1 present in the detection range of the infrared light receiving unit 14 (second areas 205 to 208 described later) based on the infrared light received by the infrared light receiving unit 14. As shown in FIG. 3, the detection system 1 of this embodiment has a plurality of (four in FIG. 3) infrared light receiving units 14. As shown in FIG. The detection unit 111 can detect the presence or absence of each of the plurality of second areas 205 to 208 corresponding to the plurality of infrared light receiving units 14 one-to-one.

As shown in FIG. 4, the second area 208 is set to include the first area 204 among the plurality of first areas 201 to 204. That is, in the detection system 1 of the present embodiment, the detection unit 111 detects each of the plurality of second regions 205 to 208 at least partially overlapping the plurality of first regions 201 to 204 based on the infrared rays received by the infrared light receiving unit 14 The person detects that there is no one H1.

The “detection range” mentioned in this disclosure means the area included in the plane at the height of the detection object 400 to be detected. For example, when the detection object 400 is the brightness in the facility 500, the above-mentioned plane is the ground 502 of the facility 500, and the detection range is the area included in the ground 502.

In addition, the control unit 11 is configured to individually control the communication unit 12, the imaging unit 13, and the infrared light receiving unit 14.

(2.2.2) Ministry of Communications 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 sent from the transmission unit 3 and a function of sending a transmission signal to the transmission unit 3. That is, the communication unit 12 is configured to be capable of two-way communication with the transmission unit 3. In the present embodiment, the communication unit 12 uses the identification information set for each of the plurality of first regions 201 to 204, and outputs the detection result of the detection unit 111 to each of the plurality of first regions 201 to 204. The communication unit 12 outputs the output information of the person detection function and the output information of the brightness detection function described later to the transmission unit 3 as the detection result of the detection unit 111.

(2.2.3) Camera Department The imaging unit 13 has, for example, 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 of this embodiment, it is also possible to detect the brightness in the facility 500 included in the imaging range 300 based on the image taken by the imaging unit 13.

Here, in the detection system 1 of the present embodiment, the imaging range 300 of the imaging unit 13 and the detection range 200 of the detection unit 111 coincide (refer to FIG. 4). In other words, in the detection system 1 of this 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. In addition, the detection range 200 of the detection unit 111 only needs to include at least a part of the imaging range 300 of the imaging unit 13, and it 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 arranged at the approximate center of the circular casing 10 and is installed on the ceiling 501 of the facility 500. In addition, the imaging unit 13 may be provided on the ceiling 501 side, and for example, may be provided on a skeleton ceiling.

(2.2.4) Infrared light receiving part The infrared light receiving unit 14 is, for example, a PIR (Passive Infrared) sensor. The infrared light receiving unit 14 detects infrared rays radiated from the human body. Specifically, if the person H1 enters the detection range of the infrared light receiving unit 14 (any of the second areas 205 to 208), the change in the amount of infrared light incident on the infrared light receiving unit 14 corresponds to the temperature difference between the human body surface and the background The amount of this can capture the activities of human H1.

As shown in FIG. 3, the detection system 1 of 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 in the center of the housing 10 formed in a circular shape.

(2.2.5) Setting section The setting unit 15 is configured to perform various settings regarding 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.

The identification information setting unit 151 sets the unique address (identification information) assigned to each of the plurality of first areas 201 to 204 set to the detection range 200 of the detection unit 111. The unique addresses allocated to each of the plurality of first areas 201 to 204 include the first address and the second address. The first address is an address used to send information about the brightness in the facility 500 (the illuminance information of the ground 502) as the detection result of the detection unit 111. The second address is an address used to send information about the person H1 in the facility 500 as the detection result of the detection unit 111. That is, in the detection system 1 of this embodiment, the identification information setting unit 151 can set the first address and the second address for each of the plurality of first areas 201 to 204. In other words, the identification information set for each of the plurality of first regions 201 to 204 is set for each of the plurality of detection objects 400 of each of the plurality of first regions 201 to 204.

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 the recognition 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 the specific area, and the identification information is set for the first area 201, the identification information setting unit 151 sets the first area excluding the specific area as the first area. The areas 202 to 204 set identification information. Specifically, when the identification information setting unit 151 is in the setting mode, for example, if the address of "1" is set for the first area 201, then "2", "3", and "2" are set 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 controller (setter) 6. That is, in the detection system 1 of this embodiment, the identification information setting unit 151 has the function of setting identification information (address) to a specific area (first area 201) based on an input from the outside (remote control 6), and Set the identification information setting mode for the other areas (the first areas 202 to 204). In this way, the identification information can be set only for a specific area, and the 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 whether or not to detect the detection target 400 for each of the unit areas 301 (refer to FIG. 4) constituting the imaging range 300, for example. The unit area 301 is, for example, an area composed of a plurality of pixels, but it can also be set in pixel units. In this embodiment, the detection range setting unit 152 sets the detection target 400 for all the unit areas 301. As a result, the detection range 200 of the detection unit 111 is set to be the same as the detection range 200 of the detection unit 111. The imaging range 300 is the same size (refer to FIG. 4).

The area setting unit 153 can set a plurality of first areas 201 to 204 in the detection range 200 of the detection unit 111. 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. Furthermore, as shown in FIG. 4, the area setting unit 153 can set a plurality of first areas 201 to 204 with a size smaller than the detection range 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 will be described 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 altitude information based on an input from the outside (for example, the remote controller 6). The height information is information about the installation height of the camera device including the camera unit 13. 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, when the first person detection function of the person H1 is detected in the detection range 200 in the human detection function, as long as the above height dimension is 2.4 m or more and 4.5 m or less, the function setting unit 154 Set the first person detection function to be valid. Also, in the case of the second person detection function that detects the number of people H1 in the detection range 200 in the person detection function, the function is set as long as the height dimension is 2.8 m or more and 8.0 m or less The section 154 validates 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 makes the brightness detection function effective. In this way, the function setting unit 154 can set the function of the detecting unit 111 based on the above-mentioned height information.

In addition, the function setting unit 154 is configured to restrict functions based on the height information input using the remote control 6. For example, in the case of the first person detection function, if the height dimension is 4.6 m or more, the function setting unit 154 disables the first person detection function and fixes the detection result of the detection unit 111 to "in". Also, in the case of the second person detection function, if the height dimension is less than 2.8 m, the function setting unit 154 disables the second person detection function and outputs the detection result of the detection unit 111 Stop.

Here, the detection system 1 of the present embodiment has both the imaging unit 13 and the infrared light receiving unit 14 as described above. That is, the detection unit 111 has: a first function of detecting the object 400 based on the image taken by the imaging unit 13; and a second function of detecting the object 400 based on the infrared light received by the infrared light receiving unit 14 Subject 400 performs inspection. 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. In this way, at least one of the first function and the second function can be set to be valid/invalid. In this embodiment, the function setting unit 154 can set the validity/invalidity of both the first function and the second function.

Also, as in the present 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 light receiving unit 14) different from the imaging unit 13, it is more Preferably, the combination of the imaging unit 13 and other sensors is different based on the above-mentioned height information. For example, when the height dimension is 4.5 m or less, since the infrared light receiving unit 14 functions normally, the detection target 400 (person H1) is detected based on the output of the imaging unit 13 and the infrared light receiving unit 14. On the other hand, when the above-mentioned height dimension is 4.6 m or more, since the infrared light receiving unit 14 sometimes does not function normally, the detection target 400 is detected only based 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 above-mentioned height.

Furthermore, it is preferable that the above-mentioned height information is also used for the setting of the imaging unit 13. For example, regarding the imaging unit 13, the focal distance to the detected 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 13 related to it.

The information setting unit 155 is configured to set output information based on the detection result of the detection unit 111 for 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 section 155 sets output information regarding the human detection function, and sets output information regarding the brightness detection function. For example, regarding the first person detection function in the person detection function, as long as the height dimension is 4.6 m or more, the information setting unit 155 will set the information indicating "present" or "absent" as output information. Also, 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 output information can be set for a plurality of functions by the information setting unit 155.

(2.2.6) Memory Department The memory portion 16 is based on, for example, ROM (Read Only Memory), RAM (Random Access Memory), or EEPROM (Electrically Erasable Programmable Read Only Memory: Electronically Erasable Programmable Read Only Memory). Read memory) and other selected device configurations.

The storage unit 16 stores the detection range 200 set by the detection range setting unit 152. In addition, the storage unit 16 stores the first regions 201 to 204 set by the region setting unit 153. In addition, the storage unit 16 stores the identification information (first address, second address) set by the identification information setting unit 151. In addition, the storage unit 16 stores the height information of the detection system 1 input using the remote controller 6. In addition, the storage 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. In addition, the storage unit 16 stores the output information set by the information setting unit 155 in correspondence with each function and stores it.

(2.3) Transmission unit The transmission unit 3 uses the unique address (identification information) allocated to each of the plurality of detection systems 1 to individually identify the plurality of detection systems 1. In this embodiment, in each detection system 1, each of the plurality of first areas 201 to 204 set for the detection range 200 of the detection unit 111 is assigned a unique address (first address and second address). site). Therefore, the transmission unit 3 uses the unique address allocated to each of the plurality of first areas 201 to 204 to individually identify the plurality of first areas 201 to 204. In addition, in this embodiment, the transmission unit 3 uses the unique address assigned to each of the plurality of control terminals 21 to individually identify the plurality of control terminals 21.

(3) Regional setting Next, the area setting of the first areas 201 to 204 to the detection range 200 of the detection unit 111 will be described with reference to FIGS. 5A to 5F. In FIGS. 5A to 5F, the detection range 200 is arranged in the first direction (the left and right directions in FIGS. 5A to 5F), and 8 unit areas 301 are arranged in the second direction (the upper and lower directions in FIGS. 5A to 5F) The 8 unit areas 301 consist of 8 columns×8 rows of unit areas 301. In addition, the number of unit areas 301 in the first direction and the second direction is an example, and is not limited to eight.

In the detection system 1 of this embodiment, as shown in FIGS. 5A to 5F, it is possible to input the number of unit areas 301 in the first direction and the number of unit areas 301 in the second direction. Set the first zone.

In Figure 5A, the constructor uses the remote control 6 to input "0" as the number of unit areas 301 in the first direction, and input "0" as the number of unit areas 301 in the second direction, and then send the input data To the detection system 1.

(4) Action Hereinafter, the operation of the detection system 1 of this embodiment will be described.

(4.1) Setting 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 a setting input for setting the detection range 200 (step S1). After that, the builder 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).

In addition, the builder uses the remote controller 6 to perform setting input for setting the first areas 201 to 204 (step S5). After that, the builder 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 (first address and second address) assigned to each of the first areas 201 to 204 (step S9). After that, the builder 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 addresses (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 stores them in the storage unit 16 (step S12).

In addition, the builder uses the remote controller 6 to input height information about the installation height of the detection system 1 (the camera unit 13) (step S13). In this embodiment, the height information can be input for each function of the detection unit 111, and the 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 builder 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 part 154 sets the function of the detection part 111 based on the input information from the remote controller 6 (step S15). The function setting unit 154, for example, sets the validity/invalidity of the first person detection function, the second person detection function, and the brightness detection function. In addition, when the function setting unit 154 is set to invalidate the first person detection function, it outputs "present" information as the detection information from the detection unit 111. Furthermore, when the function setting unit 154 is set to invalidate the second person detection function, 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 an example. For example, the detection range and address can be set in sequence after the area is set, and the address and detection range can be set in sequence after the area is set. In addition, the order of inputting height information is also an example. For example, it can be done before setting the detection range, before setting the area, or before setting the address.

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

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

In this embodiment, the monitoring input is the input generated when the first person detection function detects that the person H1 is present in the facility 500, and the brightness detection function detects the brightness in the facility 500 ( The illuminance of the ground 502) is an input generated when the situation changes rapidly. In addition, the transmission unit 3 is configured to obtain the monitoring input in order from the smaller address when a plurality of monitoring inputs are generated at the same time.

During the polling, the transmission unit 3 periodically sends a transmission signal containing sequentially changed addresses to the signal line 4. Each of the plurality of control terminals 21 obtains the control data included in the transmission signal when the address included in the transmission signal is consistent with its own address. In addition, each of the plurality of control terminals 21 replies the control state of the corresponding lighting fixture 22 as the monitoring data. The “reply” mentioned in the present disclosure means to send data to the transmission unit 3 through the current mode signal synchronized with the period designated as the reply frequency band in the transmission signal sent from the transmission unit 3.

In addition, when each of the plurality of detection systems 1 has the same address included in the transmission signal and 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. In addition, each of the plurality of detection systems 1 replies the detection result of the detection unit 111 of the corresponding first region among the plurality of first regions 201 to 204 as monitoring data.

When the transmission unit 3 detects the interrupt signal, it executes interrupt processing. During the interrupt processing, the transmission unit 3 sends to the signal line 4 an interrogation signal of the detection system 1 that interrogates the source of the interrupt signal. Moreover, the detection system 1 for the source of the interrupt signal stops generating the interrupt signal when receiving the interrogation signal, and responds to its own address.

If the transmission unit 3 receives the response 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 the detection system 1 of the source of the specific interrupt signal. In addition, the transmission unit 3 designates the address of the detection system 1 of the source of the interrupt signal, and sends a transmission signal containing the reply request data (hereinafter referred to as "reply request signal").

When the detection system 1 for the source of the interrupt signal obtains the response request data including its own address, it responds to this and responds to the monitoring data.

The transmission unit 3 completes the interrupt processing when it obtains the monitoring data of the detection system 1 from the source of the interrupt signal. In addition, the transmission unit 3 transmits a transmission signal containing control data (hereinafter referred to as "control signal") to the control terminal 21 corresponding to the address included in the monitoring data. In this way, the control terminal 21 that has received the control signal controls the relay according to the control data included 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 the present embodiment, the detection target 400 can be detected for each of the plurality of first areas 201 to 204. In addition, in the detection system 1 and the machine control system 100 of the present embodiment, identification information is set for each of the plurality of first areas 201 to 204. Therefore, the detection result of the detection unit 111 can be output to each of the plurality of first regions 201 to 204 in a state where the detection result of the detection unit 111 is divided for each of the plurality of first regions 201 to 204. That is, according to the detection system 1 and the machine control system 100 of this embodiment, the detection result of the detection unit 111 can be output to each of the plurality of first areas 201 to 204 set for the detection range 200 of the detection unit 111 .

Moreover, like the detection system 1 of the present embodiment, when the imaging unit 13 and the infrared light receiving unit 14 are used in combination, the presence of unmanned H1 can also be detected when the facility 500 is dark.

(6) Example

(6.1) Air-conditioning control The air-conditioning control in the executive room mainly measures the temperature, humidity, and CO ₂ concentration in the office space and performs feedback control in a way that is close to the target value. However, there are cases where the installation location of the sensor is limited due to the increase of column-free office buildings. When the temperature sensor is installed on the wall, etc., the temperature change in the place far away from the sensor is not immediately reflected in the measurement Value becomes a problem. Therefore, it measures the _{number of people that affect the temperature or CO 2} concentration, and controls the temperature control or air introduction control of the air conditioner before the temperature sensor or the CO _{2 concentration sensor changes (feedforward control)} ), which can provide the possibility of air conditioning control that emphasizes comfort. For example, during summer cooling, when a large number of people gather in a certain area such as a conference room, the temperature of the space rises due to heat dissipation of people, but it takes time for the temperature sensor to capture this change and perform air conditioning control. Therefore, the image sensor is used to measure the number of people, and if the number of people increases significantly, the set temperature will be lowered auxiliary, and it is considered that it is possible to perform air conditioning control without causing discomfort to the staff.

(6.2) Visualization of office utilization In recent years, due to increased attention to the reform of working methods, various improvement measures in the office are being studied. However, the changes in working methods before and after the improvement are mostly investigated by questionnaires or human visual observation. However, since the results of questionnaires are subjective and human observations are difficult to conduct continuous surveys, it is desirable to use sensing to visualize objective and continuous office utilization. For example, when the use of the discussion space is measured by the measurement function of the number of people of the image sensor (including the number of people or the number of people classified into multiple categories), the presence/absence of events can be relatively grasped The utilization of the negotiation space during the time period.
