Abstract: The simulator can not meet the sealing box, the unmanned aerial vehicle and multi user parallel using the same simulator system to simulate and debug the different software. There for, this article researched on the wireless simulator system based on multi user from the hardware, software and the associated settings etc., described the model, hardware design, software configuration and application procedure of the wireless simulator system etc. The research project was successfully tested in the new generation of train operation monitoring system (LKJ) software simulation test system, and implemented the function of remote debugging and simulating for multi plug-in software in LKJ integrated chassis.
