In the description of the following embodiments, unless otherwise specified, the first control unit 101, the wireless communication unit 102 and the first Bluetooth unit 103 are all units included in the wireless beacon module 20.

[0071] Specifically, devices with the same network number can form a network connection so that the Bluetooth gateway module 10 forms a network connection with multiple wireless beacon modules 20. When an engineering vehicle carrying a mobile wireless beacon module 30 enters an area protected from external force damage, the mobile wireless beacon module 30 enters the network coverage, and the wireless communication unit 102 communicates with the mobile wireless beacon module 30 and receives the device ID transmitted by the mobile wireless beacon module 30.
