In the past, the equipment simulation training system mainly focused on single-machine training, or generated and transmitted signals by physical objects, which made it difficult to implement in the practical application. In view of the above shortcomings, we put forward a design scheme of simulating training system based on ZeroMQ message oriented middleware, designed a practical and simple message passing standard, and developed an equipment simulation training system based on the communication model. The whole computer simulation system of the equipment simulation system is implemented and the interconnection between different operators is realized, which provides training conditions for improving the actual combat capability of the troops, and also provides a reference model for later simulation training system design of other kinds of equipment.
