地质工程自动监测硬件系统若干技术问题

SEVERAL KEY PROBLEMS OF HARDWARE TECHNIQUE IN THE AUTOMATIC MONITORING SYSTEM ON GEOLOGICAL ENGINEERING PROJECT

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。

In this paper, functional construction, development tendency, and several key problems of hardware technique in automatic monitoring system on geological engineering project are discussed. The authors put stress on the key problems of hardware technique in development of automatic monitoring system on geological engineering project. A example of automatic monitoring system setup for a large hydropower station slope mainly by the authors is introduced. For the system a lot of difficult problems were solved, such as thunder shock protection both in monitoring instruments and in the installed transducers, high precision modulation of special transducer signal in a very small module, etc.
