Research on remote monitoring and control system key techniques based on data point table

In view of many issues from the present coal gas detection systems on operation parameters, data point table-based a kind of remote multi-stage monitoring & management system frame for the coal mine gas is designed. Structure of data point table, file format of data gathering, data format of data transmission and producing and uploading basic data for remote monitoring system are integrated in the structure. The delivering data and command function of remote distance monitoring & control system for coal mine gas with standard interface of data point table message service is achieved so that it resolves the contradiction between low cost and high efficiency in the whole system. Such functions as remotely monitoring, control, maintenance, fault diagnosis, accident forecasting and decision can be implemented. The result of the applying monitoring and control for coal mine gas engineering shows that the sort of communication mode is free from the conditional restrict of geography, insures to higher speed and more reliability in the process of data transferring,.
