Description

Technical Field

[0001] The utility model relates to the field of detection, in particular to the detection of LoRa tunnel LoRa wireless power and network fault monitoring terminal products, specifically a detection device for a wireless power and network fault monitoring terminal. Background Art

[0002] The length of highways in my country is growing rapidly, and highways are widely extended to mountainous areas, and the number of tunnels is increasing. The harsh environment in tunnels (humidity, water seepage, oil pollution, dust accumulation, exhaust gas) leads to frequent mechanical and electrical equipment failures, especially power and network communication failures of equipment.

[0003] The wireless network coverage of the tunnel is relatively small, and the main communication method is wired communication networks such as optical fiber communication. When the equipment fails, the remote monitoring room can only reflect that the system or a certain electromechanical equipment cannot be used. It is impossible to determine whether it is a fault of the equipment itself, a power supply fault, or a network communication fault, and it is impossible to determine the type and location of the fault. Troubleshooting can only be done by walking into the tunnel site to check one by one. Sometimes a small problem often requires professionals to go back and forth many times to eliminate it, which is time-consuming and laborious. There are many small power and network fault points and the faults are difficult to locate, which poses a safety hazard to the tunnel. If they are not discovered and maintained in time, the accumulation of fault points can easily cause the overall paralysis of the electromechanical system of a tunnel, which can easily lead to tunnel safety accidents, resulting in casualties and huge economic losses!

[0004] The electromechanical equipment in the tunnel usually has an "equipment self-check" function, but its communication method is wired communication. When the equipment fails, it is impossible to determine whether it is a failure of the equipment itself or a failure of the communication line. When the equipment itself fails, it is also difficult to determine whether it is a power supply failure or a network communication failure. In addition, the wiring of power and network communication lines is complicated, and the fault location is difficult to locate after a failure occurs. Summary of the invention
