An intelligent information guidance and release terminal with emergency linkage function

Aiming at the problems that the function of mining information publishing equipment is single and the information of each intelligent subsystem cannot be published uniformly, an intelligent information guidance and publishing terminal which can realize the functions of voice broadcasting, dot matrix display and multi-system linkage is designed. Through the analysis of the content, mode and form of underground information release in coal mine, as well as the research on network audio communication technology, graphic display technology and network transparent transmission technology, a set of intelligent information guidance release mode based on network audio principle and audio power amplification, text release through row and column driven LED display and multi-system linkage combined with network transparent transmission is proposed. It enriches the means of information release and escape guidance, and improves the intelligent level of underground information release in coal mine.
