摘　　要：本文介绍了一种内燃机发电机组运行状态信号采集电路,包括冷却水温,机油温度、机油压力、油门位置上下限以及转速(频率)信号的采集。文中给出了较详细的硬件电路,并进行了简要分析说明,该电路可用于微机自动控制系统,且除转速外,其它信号均采用开关量形式,采集简单,便于软件编程。该电路也可用于其它需开关量控制的场合,具有一定的通用性。This essay introduces a kind ot signal collecting circuit on internal combustion engine's generating net under working condition. The singals includes cooling water tempreature engine oil temperature, engine oil pressure, upper and lower throttle limit as well as rotation speed A detailed hardware circuit is presented out and analysmg briefly in this essay This circuit can be nesd in the auto-control mucrocomputere system. Signais are assembled on-off value, except rotatom speed.It's simple and convenient to programming This circuit can be used in other situations which requires on-off value, thus it s universal.
