At present, most of the existing simulation test systems are aimed at the user, mainly simulating the actual operation process, test interface, etc., lack of simulation test for the parameters of the control equipment. In view of the current situation, a comprehensive test platform integrating system simulation and equipment test simulation is developed. The simulation platform not only tests the actual application interface, but also tests the control parameters of the control equipment. After testing, the effect is good, which meets the needs of system simulation test and control equipment parameter test, and the simulation test results are more comprehensive and complete. This paper mainly introduces its design and implementation, including the overall design, structure, working principle, test and application results.
