Research On The Sensing And Diagnosis Technology Of Electric Supply Intruding Into Telecom Cables

It will cause serious consequences to the equipment if electric supply invades into the telecom cables, so it must be detected in time, and effective precautions should be taken to prevent the possible accident, which is very significant for the communication system to work normally. Based on the above background, the problem of recognizing whether there is electric supply intruding into telecom cables is solved in this research project.Sensing, signal processing and analysis are the key technologies in this research project.The sensor with leafage, an independent innovation technology, is designed based on the layout of the telecom cables with high sensitivity. The algorithm and corresponding technology are suggested to separate signals based on the induction theory of the sensor. The perfect sensor is chosen through screening and optimizing the structure of sensor.MSP430F449 low power MCU, alarming circuit, LCD and keyboard modules are used in the hardware system. LCD can display Chinese characters, and keyboard module can be used to imput number. The man-machine interface is very easy to use. Furthermore, the system can...
