以中交京新临白高速公路所处无人区监控系统工程为实例,开发研究一套无人区无线通信监控视频传输方案。由于工程所在地为无人区,地势平坦且视距远,传统的光传输通信方案造价高,施工难度大,而且后期光缆维护成本大。借助有利的地理条件和施工现场的实际情况,开发使用一种无线传输系统,将路段的视频信号通过无线载波传送至各通信中心归集,实现视频无线传输目的。此方案的开发研究,可适用于各种不易布置有线传输通道的工程现场。
Taking the case of the unmanned area monitoring system in Beijing-Jinkaku Express-Lin Expressway as an example, a set of unmanned area wireless communication monitoring video transmission scheme was developed. Due to the location of the project is no man’s land, flat terrain and long distance, the traditional optical transmission and communication schemes have high cost, great difficulty in construction and large maintenance cost in the later optical fiber cables. With favorable geographical conditions and the actual situation at the construction site, the development and use of a wireless transmission system, the video signal of the road section through the wireless carrier transmitted to the collection of communication centers, to achieve the purpose of wireless video transmission. The development of this program can be applied to a variety of hard-wired transmission line project site.
