Research and development on robot system of mine disaster rescue second grade information detection

According to the rescue information detection robot of the mine disaster hard to reach the disaster site in the underground mine, the paper provided a new second grade disa ster rescue information detection robot system of the coal mine based on the underground refuge chamber. When a mine disaster occurred, the first grade robot of the system would be departure from a location near the refuge chamber and would be moved along the H type steel rail pre-set on the roof of the mine roadway. Until the first grade robot hard to move forward, the second grade information detection robot would be released for the disaster further information detection. Based on the design of the RSSI improved route consumption model, the system solved the poor wireless communication in the limited space and the hard to set the installation space of the relay equipment. With the simulation experiment lab of the mine roadway applied to the test of the system, the results showed that the two grade type information detection robot could have clear underground communication, clean and continuous image data transmission and stable operation of the system.
