Design of integrated monitoring system for large coal enterprise headquarters

In view of problems of coal mines under large coal enterprises, such as large number, cross-regional distribution and multiple management levels, in order to effectively improve refined management level, an integrated monitoring system for large coal enterprises headquarters was designed. Database access, file, OPC and other means are used to achieve data collection of various heterogeneous systems; the chord tangent data compression algorithm is used to compress a large amount of raw data in coal mine site; the distributed real-time database of coal mines is realized based on NoSQL technology to realize data storage and sharing; information of underground production environment, personnel distribution, equipments operation status are visually displayed based on GIS analysis and display platform and configuration technology, which can provide auxiliary decision support for safety production scheduling of coal enterprise. The practical application results show that the system realizes real-time monitoring of safe production status of production areas of the whole enterprise, which can meet the requirements of safe storage and sharing of large volume of real-time coal mine data; data display and query based on GIS mine map method, and improves data visualization and display efficiency.
