Then, the processing unit 73 transmits the linking result of linking the layout information of the target facility 200 and the wiring device B1 to the specific device 8 (step S7). The order of steps S6 and S7 may be reversed.

In the wiring equipment system 100 according to the present embodiment, each slave unit 6 acquires the spatial information in step S1, and step S1 is an acquisition step in the specific method of the wiring equipment B1.

The main configuration of a computer system is a processor and memory as hardware. When the processor executes the program recorded in the memory of the computer system, the function as the wiring device system 100 in the present disclosure is realized.

Therefore, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

Further, for example, it is not an essential configuration for the master unit 7 that a plurality of functions of the master unit 7 are integrated in one housing. That is, the components of the master unit 7 may be distributed in a plurality of housings. Further, at least a part of the functions of the master unit 7, for example, the functions of the processing unit 73 may be realized by a cloud (cloud computing) or the like.

You may. The radio wave sensor is, for example, a millimeter wave sensor. The sensor unit 66 transmits a radio wave, receives a part of the radio wave reflected by the object, and measures the phase difference or frequency difference between the transmitted wave and the received wave to measure the distance to the object. Can be done.

Further, the sensor unit 66 may have an optical sensor. The optical sensor has a light emitting element and a light receiving element, and the light receiving element receives the light reflected by the object among the light emitted from the light emitting element. Then, the sensor unit 66 can measure the distance to the object by evaluating and calculating the light received by the light receiving element. That is, it is preferable that the spatial information is acquired by using sound waves, radio waves, or reflection of light.

In the above-described embodiment, the sensor unit 66 as the acquisition unit acquires the spatial information using ultrasonic waves, but for example, the acquisition unit may acquire the spatial information from the image. In this case, the acquisition unit measures the dimensions of each space from the images of each space (first space 201 to fifth space 205) included in the target facility 200. The image is, for example, a distance image. That is, the spatial information is acquired from the image including the space in which the wiring device B1 is installed.

That is, in the specific step of specifying the position of the wiring device B1 in the target facility 200, the space in which the wiring device B1 is installed may be specified by machine learning. Hereinafter, a specific description will be given. Using the trained model, the processing unit 73 inputs (estimates) the position of the wiring device B1 in the target facility 200 by inputting at least the spatial information acquired from each slave unit 6. The trained model is generated by machine learning using the spatial information acquired from each slave unit 6 and the data including the position of the wiring device B1 in the target facility 200 as training data.

By the way, the trained model used in the processing unit 73 is generated by machine learning in the learning device. The learning device and processing unit 73 may be implemented as any type of artificial intelligence or system.

Therefore, as the training data, as described above, data with a correct answer (labeled) (Labeled Data) is used. Labeling may be done by a person. However, the learning method adopted by the learning device is not limited to supervised learning, and may be unsupervised learning or reinforcement learning.

In the above-described embodiment, the processing unit 73 specifies the position of the wiring device B1 in the space where the wiring device B1 is installed based on the spatial information in the specific step, but the orientation of the wiring device B1 is determined. It can also be specified. For example, as shown in FIG. 4B, the wiring device B1 installed in the first space 201 will be described as an example. The processing unit 73 specifies that the space in which the wiring device B1 is installed is the first space 201 based on the distance from the slave unit 6 attached to the wiring device B1. Thereby, the position of the wiring device B1 in the target facility 200 can be specified. Further, in the processing unit 73, since the distance D1 from the slave unit 601 is the longest, the wiring device B1 is attached to the first wall surface 201A or the second wall surface 201B arranged in the first direction, and the wiring device B1 is the second. It is specified that the wall surface 201B side or the first wall surface 201A side is facing. That is, the processing unit 73 can specify not only the position of the wiring device B1 in the space where the wiring device B1 is installed but also the orientation of the wiring device B1. Further, if other information regarding the space in which the wiring device B1 is installed can be acquired, it is possible to specify which of the first wall surface 201A and the second wall surface 201B the wiring device B1 is attached to. Other information is, for example, attributes such as the reflectance of the first wall surface 201A and the second wall surface 201B.

Here, the processing unit 73 specifies both the position and the orientation of the wiring device B1 in the space where the wiring device B1 is installed, but the processing unit 73 is in the space where the wiring device B1 is installed. It suffices that it is configured to specify at least one of the position and the direction of the wiring device B1 in the above. In other words, in the method for specifying the wiring device B1, at least one of the position and the orientation of the wiring device B1 in the space where the wiring device B1 is arranged may be specified based on the above spatial information in the specific step.
