摘　　要：GDAPS— 4采集站测试系统 ,是在PC机基础上构建的 ,是测试采集站技术指标的专用工具 ,在采集站维修及年检工作中使用。虽然测试功能较为丰富 ,但是在实际的使用过程中感到很不方便 ,如每次外部信号测试时 ,仅能对采集站的 2个道进行测试。本文通过分析测试系统的工作原理 ,提出了相应的技术改进思路 ,以发挥现有设备的最大利用率 ,更好地为野外地震生产服务。GDAPS -4 acquisition station test system is constructed on the basis of PC computer and is special -purpose tool of testing technical index of acquisition station, which is often used in maintenance and annual overhaul of acquisition station.Although the test function is abundant, the inconvenience in a process of practical use is often felt,because the test is only carried out for two channels of acquisition station in each test of external signal. The paper analyzed the working principle of test system and presented relevant technical improvement methods in order to display the maximum utilization ratio of instrument and better serve for seismic field production.
