Based on the AMESim simulation software and the hydraulic system simulation technology,the method of low-cost hardware-in-the-loop(HIL)simulation in Windows system is studied.Firstly,the research method uses TCP/IP communication to realize the data communication between hardware and software,and constructs the upper computer and data resolution control channel.Secondly,the USB data acquisition card is used to develop the controller,and the software and hardware IO data exchange and multi-thread design of the system are used to control the simulation data transceiver.Finally,the real-time response ability of the closed loop system is improved by using the high precision timer test.The design simulation comparison experiment improves the confidence of the system and verifies the research method.
