Abstract
This paper presents a master-slave multi-communication system designed with several micro-controllers used as master and slave controllers to set signal the lamp to realize point-to-point communication through the RS422 interface. By describing a typical example of this system and the blue print of hardware and the flowchart of software, the reliable work of the system has been proved. The circuits of system are very simple and practical, and they can be used to realize all the functions of a pilotless airborne mapping equipment. It also has a strong anti-jamming capability due to its balanced transfer scheme with single transmitter and multiple receivers. It is very efficient in protecting the integrity and correctness of transmitted and received signals, avoiding the collision of signals through the bus, satisfying the communication among several micro-controllers in a single system and forming a special communication network.
