China is a geological disaster-prone countries, Landslides brings great harm on engineering such as bridges, water conservancy, construction projects, monitoring and prewarning make sense for landslides. We sampling many methods of monitoring and prewarning for landslides,including many methods of monitoring such as geotechnical internal pressure,inclinometry technology,moisture and Sliding acceleration and attitude.The features of these monitoring means fit for monitoring and prewarning of multiparameter include of rock layer landslides internal pressure, moisture content, displacement, etc,therefore it is necessary of developing application research on multi-parameter monitoring technology for landslide.Currently, existing methods such as fiber thrust,moisture other manners is still in the stage of the primary manual monitoring,need to fieldman regularity basis to the on-site monitoring, it is waste a lot of manpower and material resources, nor can not achieve the purpose of real-time monitoring, nor can the occurrence of geological disasters prompt and timely judgments and countermeasures. On the stage there is data transmission means used of GPRS transparent transport, however, because of its great impact by shortcomings such as the signal strength, communication and performance instability in a short distance, it is difficult to meet the needs of future monitoring. This design includes data collector(fiber thrust monitoring instrument,moisture sensors,sliding acceleration and attitude monitoring instrument and other monitoring instruments),embedded microprocessor LPC2103,E2PROM memory,short messagesender,short messagereceiver and field power supply module. The design used ARM7 embedded chip timing of the IPC to the function of timers on and off, and convert monitoring data collected by geological hazard monitoring equipment (fiber thrust monitoring instrument, moisture sensors and other monitoring instruments) by the A/D conversion, split, packaged, and sent SMS by GSM module to the monitoring server, then the database server monitoring center will link up the data to analysis, finally to cmplete the function of the automatic data acquisition and data transmission.By simulated software and hardware debugging and lots of field experiment, the functions of automatic wireless transmission system have been realized wholly, data transmission stability and automatic monitoring in the field for a long time, and achieve functions of poweron by rtc alarm and setting monitoring frequency, truly achieve wireless wireless automatic monitoring features of unattended and automation, real-time and so on., and can be very easily transplanted to other monitoring systems, bedeuten a relatively wide range of practical use.
