Description
Technical field
The present invention relates to cable theft-prevention technical fields, the specially cable anti-theft system based on LORA communications.
Background technology
Electric power is the energy using electric energy as power, and invention is lifted in 1870s, the invention and application of electric power
Second of industrialization climax, since becoming 18th century of human history, one of scientific and technological revolution three times of world's generation, from this are played
Science and technology changes people’s lives, the large-scale electrical power system that twentieth century occurs be in the human engineering history of science it is most important into
One of just, by generating electricity, transmitting electricity, the power generation and consumption system that power transformation, the links such as distribution and electricity consumption form, it is by nature
Primary energy electric power is changed by mechanical energy device, then supply power to each user through transmission of electricity, power transformation and distribution.
Street lamp is a kind of mode of electricity usage, and street lamp is to show the lamps and lanterns that road provides illumination functions, refers to traffic photograph
Lamps and lanterns in bright middle road surface illumination zone, street lamp is widely used in the various places for needing to illuminate, and the installation of street lamp is with making
With too busy to get away cable, cable is typically the electricity for the similar rope that by several or several groups of conducting wires (every group at least two) are twisted
Cable, mutually insulated between every group of conducting wire, and be often twisted into around a center, entire outside is surrounded by the coating of high-insulation,
Feature with interior energization, external insulation.
Cable has power cable, control cable, compensating cable, shielded cable, high-temperature cable, computer cable, signal electricity
Cable, coaxial cable, fire-resisting cable, cable for ship, mine cable, aluminium alloy cable etc., they are led by sub-thread or multiply
Line and insulating layer composition, for connecting circuit, electric appliance etc., cable can be divided into direct current cables and exchange according to the system of photovoltaic plant

The hard plastic tube of protection or be through in mixed mud pipe is buried in underground on cable joint-box, since it is with good concealment and guarantor
Shield property, it is possible to certain anti-theft function is played, but embedded buried cable construction volume is very big, and cost is also higher, simultaneously for
Later maintenance and inspection can bring big inconvenience, so the scope of application is not wide；3., electronic technology it is antitheft：The method is on road
Electronic monitoring instrument is installed on lamp cable or road lighting cable end, and when cable is stolen, system equipment can send alarm in time
Signal simultaneously notifies road lamp management related personnel in one's power, takes measures to prevent criminal offence.
Power carrier is most popular method in industry, and signal transmission hand is utilized in electric wire burglary-resisting system
Section loads detected carrier signal on the cable of detection range, and monitoring center is connected with the carrier signal on monitored cable, and one
Denier cable outlet section causes signal transmission to be interrupted, can not be connected to signal then can automatic reported data, and digitalized electron ballast
The capacity load that device is presented in itself can cause cable run that very big capacitive character is presented, and capacitance can largely absorb intermediate frequency
The carrier signal of (100kHz~300kHz), power carrier signal is easily subject to power line impulse disturbances, therefore its transmission is reliable
Property it is poor, communication be easily disturbed.
