摘　　要：地电阻率观测系统主要包括测量系统和装置系统,在台站的日常工作中,对测量系统准确性和装置系统稳定性都需要人工检测,不仅耗时费力,而且还会受天气和人为因素的影响。本文在研究地电阻率测量误差和装置系统稳定性自动检测方法的基础上,利用单片机技术研制了地电阻率观测系统自动检测装置。利用这一装置不仅可以实现台站地电阻率整个观测系统的自动检测,大大减轻人力消耗,更重要的是可以将国家计量标准直接传递到台站,保证检测结果的可靠性和科学性。该系统经过台站长期的应用,结果表明,地电阻率观测系统自动检测装置运行可靠,可以满足台站观测系统自动检测的需求。Geoelectric resistivity observation system is composed of measurement system and out-lines system.It needs an artificial method to test geoelectric resistivity observation system in the daily work.The process is time-consuming and laborious.The test results may be influenced by meteorologic and human factors.Studying on the automation testing method in measuring accuracy and stability in geoelectric resistivity observation system,we develop an automatic testing instrument of geoelectric resistivity observation system,based on single-chip microcomputer control technology.It is labor-saving to test geoelectric resistivity observation system with the instrument in seismic station,but also can pass the national standard to observation station,ensuring the credibility and scientificity of measuring values.After a long-term operation on station,the result shows that the automatic testing instrument worked reliably and steadily,which can meet the requirement of automatic testing geoelectric resistivity observation system in seismic station.
