The management process is a process of receiving the detection result of the target detection unit 111 and managing site information regarding the situation of the site S1. According to this configuration, the situation of the site S1 can be managed. In this embodiment, as an example, the site information includes information about a person (worker) at site S1.

Moreover, the site management method further has a notification step (corresponding to "ST17" in FIG. 6). The notification step is a step of performing notification when the detection result of the object detection unit 111 satisfies a specific condition. According to this configuration, it is possible to perform notification according to the detection result of the object detection unit 111 .

FIG. 6 is a flow chart showing the first operation of the site management system 10 including the site management method according to this embodiment.

In the connection process, the builder connects the detection device 1 to the electric wiring L1 (step ST11). More specifically, the installer connects (inserts) the device-side plug 19 provided on the detection device 1 to the wiring-side plug receiver 200 provided on the electrical wiring L1. Thereby, 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 object detection unit 111 in the installation process (step ST12). More specifically, the builder uses the adjusting mechanism 16 to adjust the orientation of the housing 100 with respect to the device-side plug 19 (step ST12). Thereby, the detection range of the object detection unit 111 is adjusted. Installation of the detection device 1 is completed by the above steps ST11 and ST12.

Next, the object detection unit 111 of the detection device 1 starts detecting the worker who is the detection object T1 at the site S1 in the detection process (step ST13). The object detection unit 111 outputs 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 object detection unit 111 satisfies a specific condition (step ST14). If the detection result of the object 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 this 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 .

A management process is executed in the management device 2 . More specifically, the storage unit 21 of the management device 2 associates and records the target data and the identification information included in the communication signal received by the communication unit 22 in the management process (step ST16). That is, the site information managed in the management process includes personnel information related to people (workers) at the site S1.

On the other hand, when the detection result of the object detection unit 111 satisfies the specific condition (step ST14; Yes), the data processing unit 12 causes the notification unit 30 to perform the notification step. In the notification process, the notification unit 30 outputs a voice message such as, for example, "the 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 this embodiment will be described with reference to FIG.

The site management method according to this embodiment further includes a removal step (corresponding to "ST21" in FIG. 7). The removal process is a process of removing the object detection unit 111 from the electric wiring L1. According to this configuration, the detection device 1 can be removed after construction.

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

FIG. 7 is a flow chart showing the second operation of the site management system 10 including the site management method according to this embodiment.

The builder removes the detection device 1 from the electrical wiring L1 in the removal process (step ST21). More specifically, the installer disconnects the wiring-side plug receiver 200 of the electrical wiring L1 and the device-side plug 19 of the detection device 1 . Thereby, the detection device 1 can be removed from the electric 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 installer connects (inserts) the device-side plug 19 of the detection device 1 to the wiring-side plug receiver 200 provided on 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 in FIG. 6 are executed.
