The purpose of this utility model is realized by such technical scheme, and described device includes: send the pulse producer of pulse signal, the pulse receiver receiving cable reflection signal to be monitored, signal conditioning circuit, A/D converter, microcontroller, alarm, communication module and host computer to cable to be monitored;
The command reception end of pulse producer is connected with the instruction transmitting terminal of microcontroller, the reflected signal received is sent to signal conditioning circuit by pulse receiver, signal conditioning circuit is sent to A/D converter after processing reflected signal, A/D converter is sent to microcontroller after simulating signal is converted to digital signal, microcontroller processes rear control alarm to the digital signal received and reports to the police, and information is sent to host computer by communication module.
Further, described device also includes liquid crystal display, and the signal input part of liquid crystal display is connected with microcontroller.
Further, described signal conditioning circuit includes signal filter circuit and signal amplification circuit.
Further, described microcontroller adopts MSP430.
Further, described communication module adopts 232 or USB interface.
