针对农村配用电通信网络覆盖范围广、用户分散和成本限制等现状,提出了基于光纤网络和无线网络双平面紧耦合的通信机制.考虑到农村配用电通信网络存在信息节点多、业务类型复杂、业务流量小等问题,在光传输平面采用了以太网无源光网络(EPON)和分组传输网络(PTN)无缝对接的通信机制.相关工程应用验证了该通信机制具有可靠性高、成本低、信息隔离性强和电力业务安全等级高的优势.%Aiming at the present situation existing in rural power distribution communication network, such as wide covering range, dispersed users, and cost restriction, etc. , the two plane tightly coupled communication mechanism based on optical network and wireless network is proposed. Due to numerous information nodes in the communication network, complicated business types, while the business traffic is not big enough, the communication mechanism of seamless connection between EPON and PTN is adopted in optical transport plane. Related engineering applications verify that this communication mechanism features high reliability, low cost, strong information isolation and high security level of electricity business.
