摘　　要：设计一种新型的车载式电量仪,与传统的电量仪相比适用范围大大提高,可以随车进行测量,方便运输、搬运,可以运用到道路照明、电缆电路检测等户外环境中,而传统的电参数测量只能利用电量仪在实验室中进行测量。本设计就是在传统电量仪的基础上对其加以改进,利用独立的12 V铅酸电源在随行车辆内取电,加强其抗干扰、防震、防尘等特性,使其成为可以方便于室外现场进行测量的车载式仪器。本设计的硬件部分是以AT89S52单片机为核心,通过电流电压传感器采集的信号,经过保持放大处理,再通过A/D转换,将数字信号传输给单片机处理,将数据实时显示出来,方便对道路照明、电缆线路故障、电站抢修等进行现场分析。Design a new type of vehicular coulometers which has lager scope of application and is more easier to be transited when compared with traditional coulometers.it could work in the open air,such as lighting of roads,electric circuits and servicing.The traditional means can just be used in labs,These traditional ones are cumbersome expensive and unconvenient to be transited also,This article makes improves on the base of the traditional ones.This new design uses absolute power supply or makes use of cars＇.On the other hand,it could be a vehicular instrument with great traits of anti-interference,anti-dust,anti-yawp and so on.The hardware part of this design is on the core of SCM AT89S52.The work process of the hardware likes this,the sign of voltage or electricity collected by sensors is blowed up by amplifier,then it goes through A/D conversion to SCM,SCM manages these mathematical signal and displays the datas real time.so testers could analyses the problems on the qround.This design mainly applys in singal-phase source.
