The notification step is a step of notifying when the detection result of the target detection unit 111 satisfies a specific condition. According to this configuration, it is possible to perform notification according to the detection result of the target detection unit 111.

FIG. 6 is a flowchart showing the first operation of the site management system 10 including the site management method according to the present embodiment.

More specifically, the builder connects (inserts) the device-side plug 19 provided in the detection device 1 to the wiring-side plug receiver 200 provided in the electrical wiring L1. As a result, the detection device 1 is electrically connected to the electric wiring L1 and is mechanically held.

Next, the builder adjusts the detection range of the target detection unit 111 in the installation process (step ST12). More specifically, the installer adjusts the orientation of the housing 100 with respect to the device-side insertion plug 19 using the adjustment mechanism 16 (step ST12). As a result, the detection range of the target detection unit 111 is adjusted. Installation of the detection device 1 is completed by steps ST11 and ST12 described above.

Next, the target detection unit 111 of the detection device 1 starts detecting the worker who is the detection target T1 at the site S1 in the detection process (step ST13). The target detection unit 111 outputs the captured image data, which is the detection result, to the data processing unit 12.

The data processing unit 12 determines whether or not the detection result of the target detection unit 111 satisfies the specific condition (step ST14). When the detection result of the target detection unit 111 does not satisfy the specific condition (step ST14; No), the data processing unit 12 causes the output unit 13 to execute the output process.

In the output process, the output unit 13 acquires the target data created by the data processing unit 12 from the data processing unit 12, and outputs the acquired target data to the communication unit 14 (step ST15). In the present embodiment, since a plurality of detection devices 1 are provided, the output unit 13 outputs a plurality of target data to the communication unit 14 in the output process. The communication unit 14 creates a communication signal including the target data received from the output unit 13 and the identification information of the detection device 1, and transmits the created communication signal to the management device 2 via the relay device 3 and the network 4.

In the management device 2, the management process is executed. More specifically, in the management process, the storage unit 21 of the management device 2 records the target data included in the communication signal received by the communication unit 22 in association with the identification information (step ST16). That is, the site information managed in the management process includes the person information regarding the person (worker) at the site S1.

On the other hand, when the detection result of the target detection unit 111 satisfies the specific condition (step ST14; Yes), the data processing unit 12 causes the notification unit 30 to execute the notification step. In the notification process, the notification unit 30 outputs a voice message such as "Detection device XX is abnormal" and sounds a buzzer (step ST17). In this case, the notification unit 30 may output only the voice message or may sound only the buzzer.

(3.2) Second Example Next, a second example of the site management method according to the present embodiment will be described with reference to FIG. 7.

The site management method according to the present embodiment further includes a removal step (corresponding to “ST21” in FIG. 7).

Further, the site management method according to the present embodiment further includes a relocation step (corresponding to “ST22” in FIG. 7). The relocation step is a step of relocating the target detection unit 111 installed in the above-mentioned installation process. According to this configuration, the detection device 1 can be relocated.

FIG. 7 is a flowchart showing the second operation of the site management system 10 including the site management method according to the present embodiment.

The builder removes the detection device 1 from the electrical wiring L1 in the removal process (step ST21). More specifically, the builder disconnects the wiring side plug receiver 200 of the electric wiring L1 and the device side insertion plug 19 of the detection device 1. As a result, the detection device 1 can be removed from the electrical wiring L1.

Next, in the relocation process, the builder connects the detection device 1 to the electrical wiring L1 at the relocation destination (step ST22). More specifically, the builder connects (inserts) the device-side plug 19 of the detection device 1 to the wiring-side plug receiver 200 provided in the electrical wiring L1 of the relocation destination. This completes the relocation of the detection device 1. After the detection device 1 is relocated, steps ST13 to ST17 of FIG. 6 are executed.
