In order to protect the detector and ensure the best working state of the detector,the satellite needs to be equipped with a variety of equipments.During the testing and debugging phase,it is both necessary and urgent to develop a CAN bus communication system to simulate the function of the satellite platform for satellite-level joint testing.The CAN bus communication system based on FPGA and LabVIEW is designed for system joint testing.Firstly,the CAN bus function module of FPGA is designed to complete the data transmission between SJA1000 and bus.The USB function module is designed to complete data transmission with computer.The user interface of single unit equipment which the main program framework based on event structure for the host computer is designed by LabVIEW.Finally,such functions of the CAN bus as information transceiving,data storage,analysis and display are realized.The communication system meets the test requirements of the CAN bus communication of the FXT system.The experimental results show that the communication system is stable and reliable,and has good flexibility and portability.
