Abstract: Through the suitable system function modules, flexible protocol design and standard interface inter modules, combined with asynchronous network technologies, including data metamorphosis processing methods of coal mine monitoring data, efficient completion ports and so on, a model of coal mine safety supervision networking was proposed based on the C/S framework, which achieved the interconnection of coal mine safety monitoring systems based on heterogeneous data sources. As long as the third-party data analysis module or data processing module was made in accordance with the protocol and interface specifications, the safety monitoring system would provide seamless access for new data types, and met coal mine application requirements of other networking purpose.
