摘　　要：采用MCU+CPLD研制出铁路专用变压器测试系统装置。MCU实现频率跟踪和对测试数据的交流采样处理等,在MCU命令下CPLD作为接口负责对A/D的操作、测试结果的LCD界面显示和对继电器板的控制,达到了测试仪器整体结构精简并且二次设计快捷的效果,他作为与系统下位机的单片机同等重要的控制枢纽,对本系统至关重要。Railway transformer testing system has been developed based on MCU and CPLD, frequency tracking and disposing testing data by the methods of AC sampling have been implemented on MCU. Under the command of MCU and based on CPLD,we can manipulate the A/D,display the testing results on LCD and control the state of relay board. Just as MCU in the instrument,CPLD is also a control hinge,and plays an important role in the system, so as to monolithic structure of the testing instrument is reduced and shorten the period of second design.
