| Abstract: | The communication network of coal-mine monitoring system for work safety can be divided into 4 categories: single monitoring station-single equipment, single monitoring station-double equipment, double monitoring station-single equipment and double monitoring station-double equipment. By comparison and analysis on the mission reliability and basic reliability of these network, and comprehensive consideration of their task-fulfilling probability and maintenance cost, the paper selects double station-single equipment with double equipment fixed in high fault point as the mode of communication network so as to enhance the communication reliability of coalmine monitoring system. |
