Design of Independent Wireless Communication Network Applicable to Field

介绍了一种适用于野外的独立无线通信网络系统,利用高通Atheros处理器制成的基于IEEE 802.11a/n/ac标准的无线网络设备实现数据的远距离通信,于此基础上搭建了基于该通信网络的监测系统。经现场测试和分析可知,该系统具有双向通信、300 MHz带宽和优于30 km传输距离等功能,可实现对视频图像数据、音频信号和控制信号的可靠传送。该系统的开发可解决偏远山区无通信信号的问题,实现无信号偏远山区作业现场远距离监控,能对存在事故风险区域做出及时管控,确保作业人员安全作业。

This paper introduces an independent wireless communication network system applicable to the field, which uses the wireless network equipment based on IEEE802.11 A/N/AC standard made of Qualcomm Atheros processor to realize data long-distance communication. Based on this communication network, the monitoring system is built. According to the field test and analysis, the system has the functions of two-way communication, 300 MHz bandwidth and transmission distance over 30 km, realizing the reliable transmission of video image data, audio signals and control signals. The development of the system can solve the problem of remote mountainous area without communication signal access, realize the remote monitoring of the operation site in these areas, as well as the timely control of accident risk areas to ensure the safe operation of operators.
