Research on Integrality and Monitoring Method of Underground Monitoring System Based on Information Fusion
In order to improve the reliability of coal mine safety monitoring system, the system integrality index is analyzed and the definition of integrality and integrity degree are given. Considering that the relation between system integrity and symptom is vague, the concept of fuzzy logic is introduced to make up the deficiency of the binary logic. Through studying the monitoring method of the system integrity based on multi-sensor information fusion technology, and through synthesizing intelligently the data which come from the system and the different sensors(e.g., sub-station, telemetry channels, ground central station, relay station, application software and databases), then the universal description about the effective and reliable run of the system can be educed. Through accomplishing the estimation and monitoring of the integrality index of the safety monitoring system, the system integrality information fusion monitoring model based on fuzzy inference is established and the model is applied in the coal mine. The results show that the model can meet the requirements of the integrality and reliability of the safety monitoring system, and it is very important to the monitoring system of numerous sub-stations which have high requirements in reliability.
