Design of distributed coal-rock stress monitoring system

  • In view of problems of complex wiring, bad extensibility and low real-time performance of data transmission existed in coal-rock stress monitoring, a distributed coal-rock stress monitoring system based on wireless sensor network was designed. The system takes CC2530 as core, collects drilling coal-rock stress through sensor node. Routing node receives and transmits the collected data to sink node through ZigBee network. The sink node sends the data to upper computer for display, storage and analysis through industrial Ethernet. The test results show that the system can realize real-time and accurate monitoring of coal-rock stress with the maximum communication distance between sensor node and sink node is 50 m and has advantages of convenient operation, flexible deployment and easily to expand.
