The invention discloses a performance testing device of a
bus type
motion control system. The performance testing device of the
bus type
motion control system comprises a lower computer and an upper computer, wherein the lower computer is used for monitoring transmission data in a
motion control bus and transmitting the transmission data in the motion
control bus to the upper computer and modifying the bus data according to a transmission rule and feeding the modified bus data back to a bus
system, the upper computer is used for analyzing and evaluating the performance of the motion
control system to be tested by comparing
design data with the monitored bus data, and the upper computer designs a
test case and configures the
test case into the
data transmission rule of the lower computer and then the
test case is input into the system to be tested. According to a performance testing method and the performance testing device of the bus type motion
control system, the performance testing of the motion
control system is achieved by the monitoring of the bus data, and the motion performance of the motion control system is analyzed through the monitoring of the transmission data of the bus; or the safety performance and the stability performance of the motion control system are tested due to the fact that the test case is input into the motion control system in a mode that the transmission data of the bus are modified. The performance testing method and the performance testing device of the bus type motion control system are strong in practicability, low in testing cost, high in testing efficiency, high in practical value and good in application prospect.
