地质工程自动监测系统具有监测对象信息变化差异大，监测环境恶劣等显著特点。其硬件系统须具备监测范围广，抗干扰能力强，抗雷击等特殊功能。同时，为了适应现代化工程建设的要求，还应具备先进的智能化和网络化等功能。为此，本文对地质工程自动监测系统的功能和组成、当前的发展趋势及所涉及到一些关键硬件技术问题展开了讨论，着重总结了作者有关地质工程自动监测硬件系统关键技术问题的研究。最后介绍了作者为五强溪水电站边坡工程建立的自动监测系统，以及该系统双端防雷保护和模块化信号调理等难题的解决。
Geological engineering automatic monitoring system has the characteristics of monitoring object information variation, poor monitoring environment and other notable features. Its hardware system must have a wide range of monitoring, anti-interference ability, anti-lightning and other special features. At the same time, in order to meet the requirements of modern engineering construction, it should also have advanced intelligent and network functions. Therefore, this paper discusses the function and composition of the automatic monitoring system of geotechnical engineering, the current development trend and some key hardware technical issues involved, and emphatically summarizes the author’s research on the key technical problems of the automatic monitoring hardware system for geological engineering. Finally, the authors introduced the automatic monitoring system established for the slope engineering of Wuqiangxi Hydropower Station, as well as the solution of such problems as double-end lightning protection and modular signal conditioning of the system.
