| Abstract: | In performance testing system of the servo valve, the analog signal that transferred between control circuit and computer is interfered by EMI easily, while transferring the signal in digital form through the CAN bus can solve this problem, at the same time, the performance and reliability of system is improved. The circuit and program design of CAN bus and the realization of CAN open protocol are introduced. The application of CAN bus in testing system is discussed. |
