Network structure of mine wireless sensor network and network node deployment method

Abstract

The invention discloses a network structure of a mine wireless sensor network and a network node deployment method, and belongs to the wireless network structure and the network node deployment method. The network structure is as follows: the basic topological relation between the roadways takes a midpoint as a starting point and the graph theory as the theoretical basis; an algorithm obtains a series of roadway midlines with the same attribute through the roadway midpoint, through the optimization treatment, a roadway arc and a basic structure of the roadway line are constructed, and a roadway two-dimensional structure topological graph composed of roadway midlines is formed; the network node deployment method comprises the following steps: forming a skeleton network of the mine monitoring aiming at an underground signal attenuation factor on the basis of the roadway two-dimensional structure topological graph; establishing a communication node set by taking the underground signal shielding and attenuation as a constraint condition through the algorithm, transmitting the received information to the ground to analyze and treat, thereby guaranteeing the information transmission. The network structure disclosed by the invention has the advantages that the survivability of a coal mine safety production monitoring system under a disastrous condition is improved, and the fast reconstruction of the safety production monitoring system is realized through the coal mining and tunneling face.

Description

technical field [0001] The invention relates to a wireless network structure and a network node deployment method, in particular to a mine wireless sensor network network structure and a network node deployment method. Background technique [0002] At present, experts at home and abroad have done a lot of research on wireless sensor networks, most of which focus on ground WSN, but less research on underground WSN, especially the WSN system applied in underground coal mines. The combination of WSN and geographic information system is of great significance to coal mine safety production and information management. After the underground environment, working conditions, and personnel positioning information are collected and pre-compressed by using the underground wireless sensor network, it is transmitted to the ground in real time through the network along with information such as the location of nodes and information collection time, and then analyzed and processed by MGIS A...
