An Anti-theft Detection Method Based on Street Lamp Cable

Abstract

The invention discloses a simple, convenient and reliable anti-theft system for a street lamp cable. The anti-theft system for the street lamp cable comprises a front controller and a small loop at the end used for applying weak voltage signals for the street lamp cable when a street lamp switch is turned off; the open circuit and short circuit of the cable are judged through detecting the voltage of an access point, and meanwhile, the front controller sends an alarm and sends information to a dedicated worker to detect the circuit. The anti-theft system for the street lamp cable is suitable for monitoring and protecting the power supply cable for the street lamp and has advantages that the equipment is simple, the maintenance cost is low, the anti-theft system is not influenced by the on and off of the street lamp switch, the reliability is high, the influence to the street lamp on the circuit is avoided, and the like.

Description

technical field [0001] The invention belongs to the technical field of improving the anti-theft reliability of street lamp cables, in particular to a simple, low maintenance cost and high reliability anti-theft detection method based on street lamp cables. Background technique [0002] In recent years, due to the increase in the price of non-ferrous metals, the expansion of cities, and the increase in the floating population, the situation of theft of lighting cables has accelerated and deteriorated. According to statistics, in 2003 Hangzhou lost a total of 800,000 yuan due to the theft of street lamp cables, 2.88 million yuan in 2004, and 5 million yuan in 2005 due to the theft of cables. The loss caused by theft of cables increases by more than 30% every year, which has become a huge heartache for every street lighting manager. [0003] The commonly used carrier method is now used for anti-theft, which is not suitable for street lamp lines of public transformers. Since r...

However, since the life of lithium batteries is generally 300 times of charging and discharging, that is to say, charging and discharging once a day can only last for about 10 months. At that time, the amount of maintenance, maintenance costs and the number of false alarms will be unacceptable to street lamp managers.
