油气管道工程同轴组网监控系统

Coaxial Networking Monitoring System in Oil and Gas Pipeline Projects

油气管道工程现有监控系统清晰度不高,为提高管道运行安全性,同时降低施工难度,开发了同轴组网监控系统。该系统利用视频扫描消隐场来传输控制信号,不需要更换线缆;利用已有视频电缆传输控制信号和视频信号,只需要将前端更换为720P数字高清同轴视控摄像机,将后端更换为同轴视控硬盘录像机,采购方便、施工简单。实践证明,采用同轴组网监控系统既可节省施工时间和总体投资,又能保证系统的稳定性和可靠性。

For oil and gas pipeline project,the clarity of the existing CCTV system is not high.In order to improve the safety of pipeline operation and reduce the difficulty of construction,the coaxial networking monitoring system is developed.The system uses video scan blanking to transmit control signals,without need of changing cables; the existing video cable transmission control signals and video signals can be used,and we only need to replace the front end with the 720P high-definition digital coaxial visual control camera and replace the after end with the coaxial visual control hard disk video recorder. Procurement is convenient and construction is simple. The practice proves that the coaxial networking monitoring system can not only save construction time and total investment,but also ensure the stability and reliability of the system.
