摘　　要：钳形电流表只能测电路中的瞬间电流值,但在测量铁路的两条轨道中电流值时,需要一段时间内的两路电流变化情况进行记录并分析不平衡系数。针对这种需要,设计开发了新型智能不平衡牵引电流测量仪。仪表采用分体式设计,主机系统采用安装windows mobile5.0的PDA,测量系统基于单片机STC89C51控制的AD采样系统。测量系统和主机系统采用蓝牙技术连接进行无线通信。本仪表具有体积小、功耗低、可测交直流并实现了数据存储,实时测量多条曲线比较,不平衡系数分析,历史数据回放等功能。Tong tester can only test the instant values of electric current, and when testing the Values of electric current of the railways＇ two trackages, it is needed that record the current evolutions and analyze the unbalanced factor. Attention should be paid to this need new aptitude unbalanced traction current tester is designed and developed. It adopts separated design. The host system adopts PDA with windows mobile 5.0 operating system, and the testing system is based on the AD sampling system controlled by MCU STC89C51. The two systems adopt Bluetooth wireless communication. This instrument is compact, lower consumption, testing alternating current-direct current. It can also store data, compare the current testing lines, analyze unbalanced factor and reDlaving the historic data.
