An integrated environment monitoring system for underground coal mines--Wireless Sensor Network subsystem with multi-parameter monitoring.

摘要: Environment monitoring is important for the safety of underground coal mine production, and it also an application Wireless Sensor Networks (WSNs). We put forward integrated environment system mine, which uses existing Cable Monitoring System (CMS) as main body WSN with multi-parameter supplementary technique. As CMS techniques are mature, this paper mainly focuses on interconnection between CMS. In order to implement mines, two work modes designed: periodic inspection interrupt service; relevant supporting technologies, such routing mechanism, collision avoidance, data aggregation, CMS, etc., proposed analyzed. nodes limited in energy supply, calculation processing power, network management scheme designed four aspects, i.e., topology management, location fault management. Experiments were carried out both a laboratory real mine. The test results indicate that mines feasible all designs performed well expected.
