Description

Street light line anti-theft cutting wireless monitoring system

technical field

A street lamp line anti-theft cutting wireless monitoring system used in street lamp line management.

Background technique

Urban lighting facilities are the infrastructure of the city. Because of their frequent use, they must be in good and effective condition at all times.

Urban lighting is affected by many factors. Once there is a problem, it will hinder the normal operation of the city, and even cause or promote urban security problems, which is not conducive to urban management and the construction of a harmonious society.

Among the many factors that affect the quality and effectiveness of urban lighting facilities, cable theft is the most vicious and needs to be guarded against, and the prevention was relatively weak before.

In the past, to prevent lighting cables from being cut, methods such as power carrier anti-theft alarm, leakage anti-theft alarm and installation of communication equipment at the end of the light pole were mainly used.

Although the above method can prevent the cable from being stolen to a certain extent, and once the cable is stolen, it can be monitored and known immediately, so as to carry out remedial measures to ensure that the urban lighting is less affected. But because it is often affected by factors such as the length of the lighting line, whether the transformer is public, the lighting state, the natural conditions around the line, and the requirements for effective monitoring of the equipment itself and preventing theft of the line and cable.

Contents of the invention

The purpose of this utility model is to set a passive terminal device at the end of the network and connect it to the on-site base station through the street lamp line, and then connect the on-site base station to the alarm horn, 110 police control center, management personnel and monitoring center through the GSM/CDMA network Connected to form a street light line anti-theft cutting wireless monitoring system, which can effectively monitor the operation status of the entire network line 24 hours a day without being affected by factors such as the length of the lighting line, whether the transformer is public, lighting status, and the natural conditions around the line. Once the cable is stolen and cut, the system can detect it immediately, and can take remedial measures for the damaged cable to provide the fastest and most accurate information to improve the security and efficiency of urban lighting.

The utility model is composed of a passive terminal device, a contactor, an on-site base station, a GSM/CDMA network, an alarm horn, a 110 police control center, management personnel and a monitoring center. Two passive terminal devices are respectively arranged at the ends of the two lighting lines of AB , and connected with A, N and B, N lines respectively; A-way contactor and B-way contactor power supply terminals are connected together, the output terminals of A and B line contactors are connected with the input terminals of the field base station, A The inductance coil of the line A line is connected to the phase A line of the cable at one end, and the inductance coil of the line B line is connected to the phase B line of the cable at one end, and the other end of the two end devices is connected to the line N line back, and the line N line is connected to the N terminal of the site base station .

The alarm judging mode of the utility model is composed of two modes of lighting and extinguishing, which are combined. The operation mode of the lighting mode is to measure the current of each street light line through the high-precision current transformer connected to the on-site base station, and compare the measured value with the set value to sense the operating condition of the line; the light-off mode is set in The data acquisition module in the on-site base station and the passive terminal device form a loop through the street lamp cable line, and compare the feedback current and voltage value with the set value to sense the line operation status. The two modes are constantly switched. Once the cable is stolen and cut, the difference in the comparison signal will appear immediately, and the system will immediately alarm in all directions to achieve 24-hour uninterrupted monitoring and alarm purposes, which can effectively prevent urban lighting lines from being cut for a long time A phenomenon that affects lighting occurs.

Because the utility model adopts the passive terminal technology, it can realize 24-hour effective monitoring, has the characteristics of strong anti-interference, low false alarm rate, long service life, less initial investment, convenient for wide-scale use and maintenance, and compatible with the most advanced technology. It has wide application value and huge market potential.
