摘　　要：简单介绍GM8125串口扩展芯片的功能和特点并剖析其运用的难点,对国内外铁路地质灾害监测研究现状以及山体崩塌的原因做简要说明,对铁路地质灾害监测系统的构成要素做出阐述,同时说明其硬件和软件的基本框架。分析结果表明:在铁路地质灾害监测此类较为复杂的数据采集系统中,GM8125芯片可以很好地解决串口数量不够用的问题。The functions and characteristics of the GM8125 chip for serial port expansion were introduced briefly,and the difficulties to make use of it were clarified. The current situation for railway geological disaster monitoring and reasons for mountain collapse were also explained briefly. Elements of the railway geological disaster monitoring system were elaborated,meanwhile, the basic framework of hardware and software were illustrated. The results show that in the complicated data gathering systems such as the railway geological disaster monitoring system,the GM8125 chip can solve the problem that the numbers of serial ports are not sufficient.
