Design and Reliability Analysis of Security Mechanism of Wireless Sensor Network Monitoring System of Coal Mine

Abstract

In the design of the system, the construction and analysis of the system reliability model can help engineers to optimize the network structure. In order to evaluate the reliability of security monitoring and monitoring more comprehensively, on the one hand, the backup redundancy of key nodes is discussed on the basis of discussing the importance of key nodes of down hole sensors; on the other hand, consider the ground station and the data transmission reliability and failure analysis of dynamic base station, parallel redundancy design, three redundant data retransmission mode for data transmission, to improve the reliability of the whole system. The reliability of the proposed method of sensor network monitoring and transmission link increase, combined with the topological structure, greatly improves the reliability of the monitoring system, provide a basis for the reliable delivery of information.
