摘要：In a missile simulation training system with one-master and multi-slaves distributed system structure, a universal controller is necessary due to the system composed with several controllers. In this research, the designed controllers communicate with each other and upper control computer through RS-485 field bus. RS-485 bus including interface circuits, transmission protocol, Cyclic Redundancy Check (CRC) method and upper control test software is designed and proposed . The universal controller adopting the designed RS-485 interface circuits is connected th r ough twisted-pair and makes the simulation system, then the controller is tested in line . The results show that the RS-485 bus communicates effectively using the protocol and CRC method, data transmission rates reaches 115.2 kbps , and has a good stability.
