Description

Street lamp cable alarm

Technical field

The utility model belongs to street lamp cable burglar alarm field, is specifically related to a kind of street lamp cable alarm.

Background technology

It is bright and bustling that street lamp brings people, the more important thing is, when motor vehicle night, walking was on highway, the visual information of necessity can be passed to the driver, prevent in advance owing to the not enough traffic hazard that occurs of visual information, simultaneously, can increase and guarantee the comprehensive security and the comfort of road traffic at night.

But in recent years, the pilferage activity of street lamp cable is becoming increasingly rampant, serious the people's work and life.In order to find in time that the street lamp cable is stolen, thereby stealer is arrested, use the demand of efficient modern timely anti-pilferage alarm to become more and more urgent with the fastest speed.

Summary of the invention

The purpose of this utility model provides a kind of street lamp cable alarm, and this alarm can be cut off moment at cable and in time report to the police, and accurately alarm center is informed in the concrete orientation of this street lamp cable.

Street lamp cable alarm comprises front end main frame and terminal extension set, and the front end main frame is located at the front end of protected cable, and terminal extension set is located at the end of protected cable.Each front end main frame can be with a plurality of terminal extension sets.

The front end main frame comprises gsm module, wireless receiving module, power supply and control module, line detection module.Gsm module is with power supply and control module is two-way is connected, and wireless receiving module is with power supply and control module is two-way is connected, and line detection module is with power supply and control module is two-way is connected.

Gsm module can send to alarm center with warning message, can send address code and the alert code that Chinese information shows monitored loop to eight groups of phone numbers simultaneously.

Wireless receiving module is in order to receiving the signal that terminal extension set sends out, and transfers the signal to the power supply and control module.

Power supply and control module comprise supply module and control module, and supply module is with the required direct current of alternating current conversion cost utility model, and this module also is provided with an internal battery, when externally having a power failure, can continue operation.Control module will be carried out analysis and judgement from the signal that wireless receiving module transmits, and whether at first test the front end host line has electricity, if electricity is arranged, then send stolen warning message to gsm module; If there is not electricity, then transmit a signal to line detection module, carry out the loop and detect, transmit the information of returning according to line detection module again and carry out analysis and judgement, if any unusually, then send stolen warning message.

Line detection module detects judgement by the loop that front end main frame, street lamp cable and terminal extension set are formed, and the state that detects this loop is closure or disconnects.

Terminal extension set comprises wireless transmitter module, wireline inspection and control module, supply module.Wherein, wireless transmitter module is with wireline inspection and control module is two-way is connected, and wireline inspection and control module are connected with supply module is two-way.

Whether wireline inspection and control module detect cable ends electricity, if occur having a power failure, then sends power cut signal to wireless transmitter module.

The signal that wireless transmitter module sends wireline inspection and control module is launched wirelessly.

Supply module is with the required direct current of alternating current conversion cost utility model, and this module also is provided with an internal battery, when externally having a power failure, can continue operation.

For preventing several cable loop operation irregularities, some terminal extension sets send the abnormal alarm signal simultaneously, the wireless receiving passage blocks, and terminal extension set is provided with the time slot emission function that staggers at random, receives the signal that each terminal extension set is sent to guarantee the front end main frame.

The utility model is reported to the police promptly and accurately, all adopts corresponding design at aspects such as temperature range, vibrations, has guaranteed job stability in the open air, and is safe and reliable.

Embodiment

As shown in Figure 1, street lamp cable alarm comprises front end main frame and terminal extension set, and the front end main frame is located at the front end of protected cable, and terminal extension set is located at the end of protected cable.Each front end main frame can be with a plurality of terminal extension sets.

As shown in Figure 2, the front end main frame comprises gsm module, wireless receiving module, power supply and control module, line detection module.Gsm module is with power supply and control module is two-way is connected, and wireless receiving module is with power supply and control module is two-way is connected, and line detection module is with power supply and control module is two-way is connected.

As shown in Figure 3, terminal extension set comprises wireless transmitter module, wireline inspection and control module, supply module.Wherein, wireless transmitter module is with wireline inspection and control module is two-way is connected, and wireline inspection and control module and supply module are with to being connected.
