摘　　要：为解决译码器设备年检、月检及碎修指标的测试,设计组装了译码器系统测试仪,用来测试和校验译码器的时间精度。该测试仪主要由控制电路、同步电路、振荡电路、分频电路、驱动电路、电磁模拟振动台和数据采集存储电路组成,采用双踪示波器软件实现测试功能操作。电磁模拟振动台模仿产生野外施工井口信号,实现从外部信号到内部电路全过程的检测,测试完成后通过数据存储或打印方式保留原始测试数据,填补了译码器无测试记录的空白。To raise the accuracy and efficiency of year-test,month-test and jobbing guideline of decoder,we designed the decoder-testing instrument.Its purpose is to test and verify the time precision of decoder.Decoder-testing instrument is composed of control circuit,synchronous circuit,oscillating circuit,frequency-halving circuit,drive circuit,electromagnetism oscillating table and data collection circuit.It adopts the dual trace oscillograph software to achieve the function of testing operation.Electromagnetism oscillating table produces the up-hole signal and other testing signals just like those in field operation,and then the testing instrument checks and verifies the up-hole time of the decoder.The original testing data can be stored or printed.So the decoder-testing instrument solves the problem of decoder's having no test records.
