Abstract: The research of this paper is focused on the multifunction control board in foreign currency exchange machine . ATMEGA128 microcontroller is used to improve intelligence level of the control board, so as to realize multiple functions of real-time measuring the voltage outputs of DC power and reporting the results to host computer by needs, real-time monitoring and controlling the  switch signals, real-time monitoring the states of intelligent modules and displaying the results in LCD. The technical improvement scheme and realization method are presented. The experimental results show that the intelligent-improved multifunction control board meets the requirements of national compulsory certification and EMC, works stably, is convenient for customer service to complete machine maintenance and fault diagnosis, meets application requirements of foreign currency exchange machine.
Keywords: foreign currency exchange machine; multifunction control board; microcontroller; fault diagnosis;
