Embodiment Construction
[0010] When the present invention is used, a background monitoring and management system needs to be equipped. The sensor terminal node has the dual functions of local data collection and transmission and forwarding of adjacent node data. It can collect data under the control of the background monitoring management system and the master node, and transmit the data to the master node through a multi-hop route; the master node is the center of the network , with the role of coordinator and gateway, responsible for network configuration, management and data collection, and responsible for communication with user PCs. The background monitoring and management system is the host computer management system. In the process of use, it should be noted that the main node should be placed near the edge of the goaf from the outside of the well, and the terminal nodes should be placed on both sides of the goaf roadway, and the distance between the terminal nodes and the terminal nodes shoul...

Description
technical field [0001] The invention relates to a wireless self-organizing network temperature monitoring system applied in goafs of underground coal mines. Background technique [0002] Coal mine underground wireless communication, especially battery-powered micro-power wireless communication is an important supplement to wired communication such as mine cables and optical cables, and is of great significance in special environments. There is still a lack of effective technical means for safety information monitoring of coal mine goafs. At present, the wireless communication technology in coal mines uses the 2.4GHz high-frequency band, which has poor penetration and data is easily lost. It is difficult to meet the needs of safety information monitoring in coal mine goafs. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a wireless ad hoc network temperature monitoring syst...
