Abstract

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.

Description

technical field [0001] The invention relates to a test method of a control system, in particular to a performance test method and device of a bus-type motion control system. The test device designed based on the method can be applied to various functional test occasions of the bus-type motion control system. Background technique [0002] The performance test analysis of the motion control system is one of the main ways to improve its processing performance, safety, reliability and stability. Through the use of test tools and auxiliary equipment, according to the corresponding test cases and test procedures, the function and performance of the system are tested and verified to meet the application requirements of the specific system environment. [0003] The main purpose of the test is: 1. To find the problems and defects in the system development process; 2. To verify the execution effect of the system structure and algorithm; 3. To improve the function and quality of the sy...
