Self-networking joint for underground environmental condition wireless monitoring system

Abstract

The invention discloses a self-networking joint for an underground environmental condition wireless monitoring system, which comprises a CPU (central processing unit) micro-processing module, an A / D (analog / digital) conversion module, a sensor, a ZigBee wireless communication module and a power supply module. The A / D conversion module is connected with an input end of the CPU micro-processing module, the sensor is connected with the A / D conversion module, the ZigBee wireless communication module is connected with an output end of the CPU micro-processing module, and the power supply module supplies power for the CPU micro-processing module, the A / D conversion module, the sensor and the ZigBee wireless communication module, and is connected with the CPU micro-processing module, the A / D conversion module, the sensor and the ZigBee wireless communication module. The self-networking joint is reasonable in design, convenient in layout, low in manufacturing cost and fast in data transmission speed, can be directly connected into a network via the ZigBee wireless communication module, and effectively resolves problems that a wired monitoring system is slow in data transmission speed, long in path, high in cost and the like, cannot meet requirements of safety monitoring for mines, and has potential safety hazards.

Description

technical field [0001] The invention belongs to the technical field of downhole environment condition monitoring, and in particular relates to an ad hoc network node for a downhole environment condition wireless monitoring system. Background technique [0002] The natural conditions of coal mines are very complex, and the mining conditions are also extremely changeable. There may be various disasters in the mine, which increases the unsafety of coal mining, easily causes major accidents, and causes great difficulties for safe production. Among them, the gas disaster is more serious, and it is the main threat factor to the safe production of coal mines. Mine gas is mainly overflowed during the mining process, so the mine working face has the largest gas content, which seriously threatens the life safety of mining personnel. The oxygen content in the mine will be reduced due to the release of gas gas during the mining process. This is also detrimental to the safety of mining ...
