| Abstract: | An automatic card issuer is developed for the management of small,medium and large port trucks.The software of the power supply circuit realizes continuous output current,the input and output adopts photo-coupling circuit,motor control has exception handling and protection functions,and C language is used in the program so as to improve system accuracy and reduce system response time. The prototype and circuit debugging and testing verify that system operation is stable and reliable and can meet the requirement of transportation management of port enterprises. |
