| Abstract: | In order to improve the performance of missile control system,industrial controller is simulated for this PC/104 interface card,and then combine with CAN bus and CPLD to be a PC/104 bus interface.The bus interface receives data from ISA bus,then transmits the data frame to another bus interface by optical fiber transceiver module.At the same time,the bus interface provides the data frame transmitting by another bus interface for PC/104.Finally,the method of optical fiber self-healing interface circuit based on the CPLD is given.This design greatly improves the reliability,aseismicity and anti-interference of control system. |
