摘要
远程无线实时动态视频监控技术的应用,考虑远端部分供电及空间跨度等问题,一般有4种实施方案。方案1:近、远端所有设备就地取用220 V交流供电,信号传输敷设视频数据线,将信号传输至监控中心;此方案适合远端有220V交流电源接入、传输距离500 m左右的工程。方案2:近、远端所有设备采用220V交流供电,传输部分利用无线微波传输;此方案适合近、远端有220 V交流接入、传输距离约2 km的工程。方案3:近端用220 V交流电源,远端用12 V太阳能供电,数据传输采用无线以太网;此方案适合监控点无220V交流电源的工程。方案4:监控点采用太阳能加蓄电池直流电源供电,数据传输采用数字无线网络,建立中继站主干信号传输通道;此方案可实现30km以上远距离传输。
Considering remote side power supply and distance, there are following 4 approaches for application of remote wireless real-time video monitoring technology. （1） All local and remote equipment use 220 V AC power locally, while signals aresent to the control center via video cables. It is suitable for projects with 220 V AC power on remote side and transmission distance about 500 m. （2） All local and remote side equipment use 220 V AC power, while signals are transmitted by microwave. It is applicable for projects with 220 V AC power on both sides and transmission distance about 2 km. （3） Local equipment use 220 V AC power, while remote side is powered by 12 V solar panels, and signals are transmitted through wireless Ethernet. It is suitable for projects without 220 V AC power on monitoring sites. （4） Monitoring site uses solar power and rechargeable batteries, and data are transmitted through digital wireless network, relay station backbone signal paths are also built. Transmission distance can exceed 30 km.
