Anti-theft method for street lamp cable based on ZigBee and GSM (Global System for Mobile Communications) network

Abstract

The invention relates to an anti-theft method for a street lamp cable based on ZigBee and a GSM (Global System for Mobile Communications) network and belongs to the technical field of the anti-theft alarm of cables. According to the technical scheme, a terminal voltage measuring device is arranged in the street lamp cable to measure the voltage of the cable and is connected to a controller loaded with a ZigBee module, the controller is used for immediately acquiring voltage of the cable, the voltage of the cable is sent to an upper computer through the ZigBee module, a GSM module is loaded in the upper computer and is used for sending the voltage of the cable to a municipal administration department at regular time, warning information is sent immediately when the voltage is abnormal, and an error site of the cable is timely positioned through a ZigBee subnet node label, so that the problem can be conveniently and timely solved by the municipal administration department; if the cable is stolen, the steeling time and site can be rapidly determined, so that the survey of public security organs is facilitated. The method has the advantages that the cost is low; multiple links such as testing principles, reporting manners and the like are optimized, so that the cable steeling warning reliability and accuracy are greatly improved.

Description

technical field [0001] The invention relates to a street lamp cable anti-theft method based on ZigBee and GSM network, which is used to solve the problems of street lamp cable real-time monitoring and active alarm anti-theft. Background technique [0002] At present, there are several ways to prevent theft of street lamp cables: [0003] Terminal voltage measurement method, which adopts the installation of voltage detection and communication devices at the end of the cable, and is powered by a fixed power supply to communicate with the master station through wireless communication. During the day, the front-end distribution box supplies 48V DC voltage to the cable, and at night, it normally supplies 220V AC voltage. Once the end power is cut off, the cable is considered stolen and the main station is called immediately. This is one of the most reliable cable anti-theft detection methods at present, with low false alarm rate, accurate positioning, and fast response. However,...

AI Technical Summary

Problems solved by technology

This is one of the most reliable cable anti-theft detection methods at present, with low false alarm rate, accurate positioning, and fast response. However, certain problems have been found after practice: the initial investment cost and installation difficulty are relatively large, and wireless communication is required at the end of the street light cable. Equipment, antenna installation and configuration issues, lightning protection measures, etc.

However, there are many problems in the power carrier method: (1) No anti-theft during the day: the current street lighting system cannot supply power during the day, so the basic condition for the existence of power line carrier communication - the absence of power carrier, resulting in the failure of the cable anti-theft to work normally, which is exactly the practical application The key time period for cable theft;

[0011] (2) The power line carrier anti-theft is based on the modulation signal based on the power line signal. In the actual circuit, with the individual differences of the working voltage and power load, the reliability of the power line carrier is severely tested, and the anti-theft reliability is not high. In actual use, false alarms, The false negative rate is about 1%
