Background technique

In the power system, the grounding wire is the most direct measure to protect workers from electric shock. However, at present, in my country, at the construction site of power engineering operation and maintenance, it is generally used to check the temporary grounding wire manually. The method is primitive, inefficient and prone to safety hazards. ACCIDENT. Most of the existing ground wire control systems use wired transmission methods such as RS485, or paid communication methods such as GPRS, which require a lot of manpower and material resources.

Patent No. CN110146769A discloses a ground wire monitoring device, EOS monitoring system and its method. The EOS monitoring system includes external electrical equipment, AC charging piles, external equipment ground stakes and ground wire monitoring devices.
