Before the present invention is described in detail, it should be noted that in the following description, similar elements are represented by the same numbers.

Referring to FIG. 1, a first embodiment of the wireless network construction method of the present invention is implemented by a wireless network construction calculation system that includes multiple wireless devices, a server 1, and a wireless network construction calculation system. It is connected to the management terminal 14 of the server 1 through a communication network 100. Among the wireless devices, there is at least one master connection device 11 that is set to have a connection relationship with the server 1. Terminal 1 has a child wireless device 13 in a connection relationship.

In this embodiment, the implementation of the server 1 can be a personal computer, a cloud host, or a server, but it is not limited to this.

This embodiment sequentially includes a creation process, a connection process, and a Repair procedures, a search procedure, and a judgment procedure.

Referring to Figure 2, the establishment procedure illustrates how the server 1 establishes the connection structure between the wireless devices and the routing table corresponding to the connection structure, and includes a step 201, a step 202, a step 203, and a step 204, a step 205, a step 206, a step 207, a step 208, a step 209, a step 210, and a step 211.

In this step 201, for each master wireless device 11, the master wireless device 11 sends a connection message including its own device identification code, connection address, and positioning information to the server 1.

In the step 202, for each master wireless device 11, the server 1 establishes a connection with the master wireless device 11 according to a new request from the management terminal 14 and the connection message from the master wireless device 11 Connect.

In this step 203, for each sub-wireless device 13, the management terminal 14 selects a target main wireless device 11 from the at least one main wireless device 11 to have a connection relationship with the sub-wireless device 13.
