Abstract

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.
