| Video Surveillance System is applied in drilling site, the driller can completely view the situation of the drill block. Through this system, these operators can be away from danger of drilling site while they observe the scene, and they can also have a broader view.The main task of this research is based on the existing video surveillance system in drilling site, realize the multi-channel video signal input, use digital video recorder as the core design to realize the storage and network transmission function. Analysis the several digital video coding standard, include H.261, H.262, H.263, H.264 of ITU-T and MPEG-1, MPEG-2,MPEG-4 of Moving Pictures Experts Group. Through comparing superiority and suitable place of different kinds of the standard, show it is the most appropriate to select H.264 in the video surveillance system of drilling site.Use micro controller to design the special operating handle for the driller to realize the operation convenient, fast, efficient. Increase the video in the driller operating room based on multi-channel Video Surveillance, and store part of the videotape, meanwhile,the videotape can also be sent to the duty room cadres and oilfield technology experts, which can real-time understanding to the entire drilling site. Based on the network transmission,establish expert video management system, the remote control can be realized in the true sense, and the site problems can be solved better, greatly enhance the work efficiency. For the development of test and field application test of improvement, improve the performance of this video Surveillance system. Study on the adaptability of the environment at the same time of processing the video anti-jamming aspects. |
