Research and Realization on the Communication Subsystem of Gas Supervision System for a Colliery

Aimed at the gas supervising system for a colliery in a certain mining industry group,a design of the communication subsystem is put forward.The composition and function realizing flow of the communication subsystem is described while the communication protocol is analyzed and established The system is designed by using VB program and its performance is enhanced by use of full-duplex communication,the data format of data frames and timed detection means,which provides a high efficiency and credible communication platform for the gas supervision system of a colliery.
