Cable anti-theft alarm remote alarm and detection alarm method thereof

Abstract

The invention discloses a cable anti-theft remote alarm which is characterized in that the remote alarm comprises a single-chip microcomputer module, a detection module, a communication module and a power supply module; the detection module is provided with a signal transmitting interface, a signal receiving interface and a comparison module; the signal transmitting interface is used for transmitting a test signal to a cable, the signal receiving interface is used for receiving a signal returned by the cable, the comparison module is used for comparing the value of the signal returned by the cable with a preset value and outputting a corresponding level signal, and the output end of the comparison module is connected with an I / O port of the single-chip microcomputer module; the communication module is connected with a serial port of the single-chip microcomputer module; and the power supply module is connected with the other modules and is used for supplying power to the whole alarm. The alarm can monitor the cable in real time, and send an alarm short message to a manager at the first time when theft is detected, so as to reduce loss to the minimum. The alarm is not limited by time and terrain, and is high in concealment and flexible to use.

Description

technical field [0001] The invention relates to the technical field of design security, more specifically, it relates to a cable anti-theft alarm and a detection and alarm method thereof. Background technique [0002] In society, incidents of cable theft happen from time to time. In order to avoid cables from being stolen, some burglar alarms have appeared on the market. However, the existing alarms all go to detect whether the cable is powered off or lack of phase to report to the police when the cable is charged, and cannot detect the uncharged cable. At the same time, there is a risk of personal injury when the cable is live. [0003] In railway power construction, the cable construction period is long. When the cable is laid on both sides of the tunnel or the line, and the cable is not powered, the cable is left unattended for a long time, and it is very easy to be stolen by criminals, thus causing major economic losses to the construction unit. [0004] Since there ...

However, the existing alarms are all to detect whether the cable is powered off or lack of phase to alarm when the cable is charged, and cannot detect the uncharged cable.

At the same time, there is a risk of personal injury when the cable is live

[0003] In railway power construction, the cable construction period is long

When the cable is laid on both sides of the tunnel or the line, and the cable is not powered, the cable is left unattended for a long time, and it is very easy to be stolen by criminals, which will cause major economic losses to the construction unit.

[0004] Since there is no anti-theft alarm for cables laid at present, in order to prevent the cables from being stolen, the construction unit can only send people to inspect them. The cable is stolen, and the manual inspection is greatly disturbed by the weather and terrain, which leads to poor inspection effect and cannot effectively solve the problem of cable theft
