Abstract: The observation of frozen wall can not be observed directly, and it needs to be monitored by an effective monitoring system. In view of the mine freezing point, long distance and other related problems of monitoring, in this paper, the software scheme of the first-line bus monitoring system for mine formation freezing using the first-line bus type development technology is proposed, and the system is introduced in detail. The system has been proved to be of high reliability, stability and practicability.
