At present, my country is one of the countries with the most serious cable loss in the world. Because the cables are exposed outside, thieves can take advantage of them. The theft of power transmission cables is very common all over the country. The average annual loss in small and medium-sized cities exceeds one million. At present, there is no effective means to prevent and control cable theft. The commonly used method Generally, manual on-duty and inspection methods are used, but this method consumes a lot of labor and has high costs. At the same time, it is impossible to monitor the power supply line at all times. According to the survey, there are key areas for criminals to steal cables, but there is no fixed time. Criminals will use inspections During the gap and unattended time period, illegal and criminal activities are carried out, and the phenomenon of cable theft and cutting cannot be completely avoided. These not only cause huge economic losses to the power industry, but also threaten the country's power, communications and people's lives. Therefore, it is urgent to provide an effective monitoring system to realize real-time monitoring and effectively avoid cable theft. CN 101201960A discloses a cable anti-theft alarm system, which is composed of a wireless phone, a charging circuit and a transformer. The circuit and the transformer are connected, the disconnection detection circuit is also connected to the loop bridge circuit through the zero line of the monitored power supply line, the transformer is also connected to the charging circuit, and the transformer is connected to the loop bridge circuit through any live wire of the monitored power supply line. This cable anti-theft alarm system has realized real-time monitoring, but can only know that the failure occurs, and sometimes criminals escape quickly, and similar situations will still occur, resulting in the situation that the police do not receive benefits.
