Wireless Sensing Node Deployment of Coal Mine Based on the Probability Sensor Model
Ya Wang, Mengran Zhou · 2017
The wireless sensor networks (WSN) with the distributed network protocol, the node with the abilities of sensor, wireless communications and data processing.It can monitor, aware and acquire the information of environment or monitoring object in real time.The coal mine can overcome the difficulties using the wireless sensor networks, and realize its coal mining, boring work surface, goaf gas, staff orientation such as wireless access detection.After the disaster, WSN can quickly reconstruct the environmental monitoring system to enhance the coal mine safety surveillance system in disaster conditions remaining.This paper analyses the characteristics of narrow space in the coal mine laneway, gives the probability sensor model (PSM) for laneway narrow space, analyses the relationships among perceived probability, effective awareness radius and other sensing parameters.For the semi-enclosed narrow space, to meet the maximum coverage and effective redundancy, it gives the node deployment scenarios in laneway, to lay the foundation for reliability research of wireless sensor networks in coal mine underground.
