RS-485 Bus Design of a Missile Simulation Training System
Abstract: 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 through 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.
