1: System Overview

  A forest area within the jurisdiction of Pingjiang County. This forest area is located in the mining area and reservoir water source area. In order to effectively manage the ecosystem in the forest area under its jurisdiction, in order to achieve fire prevention and water source ecological management. Seven monitoring points were established within the jurisdiction of the forest area, and each monitoring point was installed with two surveillance cameras, namely a traditional high-definition camera and a camera with thermal imaging functions, which are located at important points in the forest area.

2: Project introduction

This system installed monitoring towers in the seven areas of Qingmei Bay, Zhangjia, Qishudong, Nanqiaojie, Yupen, Daqiaojian, and Jinyan in the reservoir area. As shown in the figure below, Golden Weir is 18 kilometers away from the township government monitoring center. This monitoring point is transmitted back to the monitoring center through the operator's fiber network. The monitoring points where the remaining six points are located do not have any wired network access. Therefore, wireless bridging and other methods are used to transmit the signals to the Heroes Monument, and then return the signals to the monitoring center via the optical fiber network. Among them, the three points of Qingmei Bay, Zhangjiajia, and Qishudong need to be bridged step by step to realize signal transmission.

Three: Solution

This set of wireless transmission solutions uses point-to-point wireless bridging video transmission for all six monitoring points due to the monitoring point orientation and transmission restrictions. The LA-5839 5.8G 300Mbps outdoor antenna integrated wireless bridge is used uniformly, and the transmission distance is 5KM +, which fully meets the bandwidth rate requirements of each wireless monitoring point and multiple relays. In the wireless configuration process, each group of communication uses different frequencies and ID numbers to avoid mutual interference. At the same time, network security transmission is realized through network encryption and ID hiding.
