摘　　要：为解决测井仪器故障分析困难的问题 ,在研究分析了井下仪器 4种信号的基础上 ,开发研制了单片机信号模拟器。该仪器的核心是 8751单片机 ,通过软件控制能产生模拟井下仪器中的直流电压信号、声波信号、脉冲计数率信号和PCM 350 6脉冲编码信号 ,用于检测测井仪器地面部分的工作状态。从实验结果可以看出 ,它完全能够模拟井下仪器产生的井下信号 ,对油田测井仪器检测自动化具有较高的实用价值和广阔的应用前景。A single chip computer simulator is developed on analysis of four kinds of signals from downhole tools in order to overcome tool failures. The simulator′s core is 8751 single chip computer, signals from downhole tools simulate by the simulator for detecting the surface tools. The paper introduces single-chip-computer simulator′s design idea, system structure, working principle and software realizing methods. Experimental results show the single-chip-computer signal simulator can fully simulate signals from downhole tools, it has higher practic value and wide application prospects for automatic detection.
