基于单片机MSP430F149的通信线缆在线监测系统

On-line Monitoring System for Communications Cable Breakdown Fault Based on MSP430F149

本文针对通信线缆的断线故障,提出了一种利用分布式的监测系统来实现对障碍的及时报警和故障点位置检测的整体方案。使用单片机MSP430F149和FPGA构成一个高速的可变采样速率系统,实现对通信线缆障碍的检测,并用DTMF拨号芯片MT8888和嵌入式MODEM芯片MSM7512配合实现远程报警和数据交换的功能。整个系统具有易于控制,灵活和可扩展的特点,解决了通信线缆的在线监测问题。

In this paper, an on-line monitoring system is brought forward to check and measure breakdown fault of communications cable.The system can achieve functions, both fault-alarm and fault-location. the system is made up of two parts： the high and alterable speed sampling system achieved by using MSP430F149 and FPGA, and the remote alarming and data exchanging module consisted of a monolithic DTMF transceiver MT8888 and a monolithic MODEM MSM7512.The whole system is flexible, extensible and easy to be controlled.It’s valuable to deal with the communications cable breakdown fault in time and valuable to reduce the economic loss caused by the fault.
