基于EPON系统的电力ONU模块设计

摘要

Aiming at the shortage of current power communication mode in terms of stability and security,power optical network unit(ONU) modules are designed based on ethernet passive optical network(EPON) system.A modularization method of ONU equipment is adopted to simplify the network structure of power communication,and the compact combination design of the power ONU modules is adopted to reduce the cost.In the hardware part,the design and implementation method of power ONU modules is described in detail,analyze the main control chip,optical transceiver module,data storage module and peripheral circuit;in the software part,the transplantation of operating system and the application program design process are given.Test results show that the power ONU modules meet the requirements of power communication.%针对当前电力通信方式在稳定性与安全性方面的不足,设计了基于以太网无源光网络(EPON)系统的电力光网络单元(ONU)模块.采用电力ONU设备模块化的方法简化了电力通信的网络结构,采用电力ONU模块精简组合设计降低了成本.阐述了电力ONU模块的硬件设计实现方法,对主控芯片、光收发模块、数据存储模块以及外围电路进行了分析;软件部分给出了操作系统移植与应用程序设计流程.测试结果表明,电力ONU模块满足电力通信的要求.
