Abstract:According to the actual situation of production, a set of surveillance system of the cage of the mine shaft is designed in this paper. And the video image will change when the cage’s position changes, and it can realize to switch the video interface automatically. In order to realize the function of the automatic switching, this paper uses software design instead of using video converter, which reduces the cost and improves the economic benefit. Capturing video uses the VFW technology in VC++ to get the real-time video data and it reduces the dependence of hardware and it also increases the compatibility and portability of the program. If the program is directly transplanted to the monitoring system of the mine hoist, it can realize monitor control integration of the cage of the shaft.
