Wireless sensor device and method used for coal field fire zone parameter dynamic monitoring

Abstract

The invention discloses a wireless sensor device and a method used for coal field fire zone parameter dynamic monitoring, and belongs to the field of wireless sensing system used for large-scale coal field fire zone monitoring. The wireless sensor device is composed of parameter acquisition and wireless transmission nodes, and terminal signal receiving stations in coal fields. The parameter acquisition and wireless transmission nodes are composed of a plurality of sensors, A / D converters successively connected after signal linear amplification, single chip microcomputers, infrared thermal imaging monitoring systems, and wireless transceiver modules; the terminal signal receiving stations are composed of the wireless transceiver modules, single chip microcomputers, and host computer servers; the wireless sensor device can be used for continuous monitoring on temperature, CO, and CO2 parameters of coal fields, and real-time transmission of the parameters to the signal receiving stations. The signals are stored in a database via the signal receiving stations, and displayed on a server visual interface; analysis on the coal field fire zone acquired parameters is carried out using server operating software; tracing prediction, early warning, and back checking on coal field spontaneous firing tendency are realized; and measures can be adopted in time so as to avoid generation and enlarging of coal field fire.

Description

technical field [0001] The invention relates to a wireless sensor device and method for monitoring fire area parameters, which is characterized by a wireless sensor device and method for dynamic monitoring of coal field fire area parameters. [0002] It is suitable for wireless monitoring and early warning of spontaneous combustion in large coalfield fire areas. Through the dynamic wireless monitoring of spontaneous combustion parameters in coalfield fire areas, the tracking, forecasting and review of coal spontaneous combustion trends in coalfields can be realized, and measures can be taken in time to prevent the occurrence and expansion of coalfield fires. Background technique [0003] Coalfield fire is a global disaster, which seriously threatens human health, natural environment and coal mine safety production, and causes huge resource loss and environmental pollution. Fires are common in coal fields in many countries and regions. my country's coal production and consum...
