Design and implementation on communication system of maintenance platform applied to self-propelled guns fire control and measurement system

In order to fulfill the requirement of maintenance platform applied to self-propelled guns fire control and measurement system, a communication scenario based on RS-485 serials communication network is designed. Data communication between one control terminal and multi-sampling terminals can be realized. The structure of this communication system is presented, the data process flow at sampling terminals, communication protocol and conversion circuit between RS-232 and RS-485 interface are described in details. The software programmed at control terminal is emphasized, which includes the method of serial communication using Windows API functions, part of program codes and human-machine interface and so on. This communication system is tested and can be applied to maintenance platform of self-propelled guns fire control and measurement system.
