摘　　要：季冻区路基在冻融作用下常常发生冻胀、融沉等病害,其中路基土的温、湿度水平是致灾的重要因素。针对现有监测手段单一,路基温、湿度全时空监测困难等问题,利用远程无线传输技术,设计了一种基于GPRS(通用分组无线服务)通信技术的季冻土路基温、湿度双参数监测系统,可以实时监测路基温、湿度变化。系统采用土壤专用的温、湿度传感器作为采集终端;以STC89C52单片机作为主控制器,通过编辑AT指令控制GPRS连通网络和数据收发,实现温、湿度数据远程传输和存储。经实际验证该系统采集精度高、稳定可靠、操作方便,可实现对季冻土路基内部温、湿度的实时无损监测。The seasonal roadbed of the frozen soil often frost,heave,thaw and settle under the circumstance of frozen and thawed. Among all the factors that cause such damage,temperature and humidity levels are the most significant. According to the problems like too simple measure and monitoring methods,hard to have all space-time monitoring and measure of roadbed and so on in the past,we use remote wireless transmission technique to design two-parameter of monitoring and measure system of temperature and humility in the roadbed of seasonal frozen soil based on the GPRS（General Packet Radio Service） communication technique which can real-timely monitor and measure the change of temperature and humility of the roadbed. The system uses special-purpose soil sensors of temperature and humility as collection terminals; uses STC89 C52 single chip as the main controller to achieve remote transmission and storage of data of temperature and humility by editing AT commands to control GPRS network connection and data sending and receiving. We have tested this system and prove that it is a system of high-precision of collection,stabilization,reliability,simple operation which can be used for real-time and undamaged monitoring and measure of temperature and humility of inner-roadbed of seasonal frozen soil.
