Abstract

The invention relates to a wireless positioning method of mine equipment and a spraying dust suppression control method of hydraulic supports. The two methods have the following beneficial effects: positioning is realized based on the signal intensity values of wireless data; wireless modules on the hydraulic supports and a wireless module on a coal mining machine are distributed on two parallel lines and form a communication network based on Zigbee wireless positioning technology; after successful networking, a node B on the coal mining machine begins transmitting broadcast data ceaselessly every hundreds of ms after simple handshake response, nodes A on the hydraulic supports closer to the node B receive the data and obtain the address of the node B and then process the signal intensity values of the received data and finally return the signal intensity values to the node B point to point by groups, and the node B computes the advancing position; and in addition, automatic spraying dust suppression control of the hydraulic supports in the place in which the coal mining machine is positioned can be realized while the coal mining machine is precisely positioned by utilizing Zigbee wireless communication, thus avoiding the defect that the infrared transceiver technology is easy to block by dust, equipment and human bodies and accordingly loses functions.

Description

technical field [0001] The invention relates to a wireless positioning method of mine equipment and a hydraulic support spray dust control method. Background technique [0002] The coal mining industry is an extremely important pillar energy industry in my country's economic system. However, compared with some large coal mining countries with advanced technology, my country's coal mining conditions are at a lower-middle level, and there are very few mineral resources available for open-pit mining. , most of the coal fields belong to underground mining operations, and the conditions are more complicated. Due to the aging of coal mine safety measures and equipment and the lack of safety facilities, when mine accidents occur, a large number of people and property losses are often caused. The safety of coal mines needs to be solved urgently. . [0003] At present, the positioning of mine equipment mostly adopts the infrared method. The disadvantage of this method is that the infr...
