Anti-theft device and detection method for 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 reliability of street lamp cable anti-theft, 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 scale of cities has expanded, and the floating population has increased, and the theft of lighting cables has accelerated. According to statistics, the total loss of Hangzhou City due to the theft of street lamp cables in 2003 was 800,000 yuan, in 2004 it was 2.88 million yuan, and the direct loss due to cable theft in 2005 was as high as 5 million yuan. The loss caused by the theft of cables increases by more than 30% every year, which has become a huge heart disease in the minds of every street lighting manager. [0003] The carrier method commonly used now is for anti-theft, which is not suitable for the street lamp circu...

Problems solved by technology

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.
