Wi-Fi Technology Application In The Construction Of Video Surveillance Systems In Strong Electric Field Interference

Earth station construction in Tianjin Yangliuqing wave transmitting station basedon this earth station plus the binding mode wave transmitting station in the country isrelatively rare. Since2008, the importance of safety broadcast more and moreprominent task, especially TV uplink system directly managed by the StateAdministration of Radio, safety equipment has become a priority, it is necessary tobuild a stable and efficient real-time video surveillance system to monitor variousaspects of the broadcast. However, the electromagnetic wave emitted by powertransmission towers strong, long-distance video transmission to the enormousinterference, textured picture eventually received serious, intermittent, or even black,can not meet the needs.In recent years, the rapid development of wireless network technology, to solvethis problem provides a new way of thinking. The main purpose of this paper is tostudy through wireless LAN technology, wireless LAN control erection method,component parts, related technical indicators and important parameters, theconstruction of a Wi-Fi-based video surveillance system technology to solve specificfields in the earth station environment long distance video transmission interferenceproblems. While leveraging the advantages of wireless technology to lay thefoundation for future system expansion.The main research method is the first theoretical analysis combining actualmeasurements demonstrate the feasibility of using Wi-Fi technology, and then selectthe appropriate place to set up the camera to establish monitoring points, subregionalmonitoring points will be connected together and to the routing device, and finallythrough antenna signal returns the total console thus erecting a video surveillancesystem, the main components need to use wireless routers, bridges, directionalantenna, omni-directional antennas, hard disk recorders, cameras, smoke detector,and a computer terminals.Through this security video surveillance system, we can all important technicalfacilities and safety nodes within the earth station for real-time monitoring, the firsttime to get the relevant information, so while ensuring Tianjin earth stations in eachdevice to work properly in a safe environment save a lot of manpower and resources.
