In view of the problems in the mine hoisting system over-volume accident, this paper takes the vertical shaft friction type mine hoisting system as an example to establish the mechanical model of the mine hoisting system over-roll protection, and analyzes the precautions and forces of the over-roll protection process. Provide a theoretical basis for the design and safety inspection of the mine hoisting system to avoid accidents during the mine lifting process.
In view of the problems of inflexible saving and calling data and low reliability and being difficult to compatiable with other system for domestic stage video monitoring system, the authors proposed a video supervision and scheduling system of stage based on IP camera. Audio and video technology, multimedia technology and computer network technology were used in the stage video surveillance and scheduling system. The structure of the system were designed and the main functions of the system were tested. The results show that this system can satisfy the modern stage performance effect and monitoring requirements.
