地层冻结远程监测系统的设计与应用

Design and application of remote monitoring and measuring system for ground freezing

神木冻结工程中具有多井监测、测温点相对集中、空间分布远的特点。为实现多井筒冻结温度场同期监测,基于集中管理、分散监测的设计思想,应用无线数传电台及具有强力驱动性能的一线总线监测模块,构建、设计了地层冻结远程监测系统。在每个井筒的监测设计中,将测温孔与冻结器回水的温度测点制成多根测温电缆全部接至一个测温模块,使监测分站精简很多;监测模块的搜索与监测相分离的运行模式,保证了系统的可靠运行。所开发的监测系统取得了完整的监测信息,为冻结工程的顺利进行提供了保障。

There were multi mine shaft monitoring and measurements,and temperature measuring points with the relative contracted and long space distribution features in the Shenmu freezing project.In order to have the design idea of the same time monitoring and measure- ment,concentrated management and separated monitoring and measurement for the freezing temperature fields of the multi mine shafts,a remote monitoring and measurement system of the ground freezing was designed and set up with the radio digital transmit...
