Internetwork coal industry control network and IP networks to exchange research

In this paper, the status of research comparative information standards at home and abroad on the basis of the analysis of the current mine information standards problem. In order to effectively improve the efficiency of coal mine of information technology and normative, eliminate information silos, improve the degree of data sharing, application system to achieve interconnection of information through the construction of the coal industry and coal industry standard system control network and the IP network to achieve data exchange standards this goal. The application of data exchange standards to unify the content and format of coal mine safety monitoring system data exchange management departments at all levels in order to achieve mine data sharing and data exchange. Therefore, building the coal industry, information technology standards, under the guidance of the standard system of research needed to develop mines data exchange standards is necessary.

Development of coal mine safety supervision system of methane monitoring substation

Coal mine methane monitoring substation is an important component of coal mine production safety monitoring system, it and flameproof and intrinsically safe power supply and a variety of mine sensors together, monitor and control for environment parameters of mine remember parameters at the central station management. In RS485 communication system for data exchange means, so compared to the traditional monitoring system, there are obvious advantages in wiring, data transmission error. Performance of methane monitoring substation based on the reliable, stable operation, high efficiency of data transmission, monitoring of the environment in a timely and effective. On the safety production of coal mine, and play a certain role.
