System Four数字传感器工作与测试原理分析

Work principle of VectorSeis and test principle

由于数字传感器在结构上不同于传统检波器,其测试项目也就与传统的检波器大不相同,且测试项目也少很多,只有遥测接口测试、传感器畸变测试及VOR测试三项。本文详细阐述了System Four数字传感器的组成、工作原理、测试原理,并介绍了维修、拆装数字传感器时的注意事项及其常见故障的解决方法。

Because of digital sensor different from traditional geophone structurally,the test items are different from traditional geophone and far less,and only there are three items of tests: remote interface,distortion of sensor and VOR.The paper expounded in detail the composition of VectorSeis in System Four,work principle,test principle and introduced the matters needing attention in maintenance and dismount and mount of digital sensor and solution of other common troubles.
