摘要

依据现有的电力通信系统资源,设计并实现一种基于Wi-Fi技术的语音网关设备,可在应急现场搭建语音通信网络,并能通过卫星网络与应急指挥中心进行通信。语音网关将Wi-Fi技术与IP PBX软交换架构相结合,克服了传统语音通信方式存在的缺陷,可提高电力通信系统保障电网安全稳定运行的能力。最后通过实际测试,验证了设计的语音网关设备通信性能指标可以满足应用要求。
Based on the existing electric power communication system resources, this paper gives the design and implementation of a voice gateway based on Wi-Fi technology, which can set up voice communication network in emergency site, and can communicate with the emergency command center through the satellite network. The voice gateway combines the Wi-Fi technology and the IP PBX soft switch architecture, overcomes the defects of traditional voice communication mode, and improves the electric power communication system ability to ensure the stable operation of power grid. The practical test results have proven that the designed equipment can meet the application requirements.
