某电能量远方终端双平面网络接口设计

摘要

为实现某电能量远方终端接入双平面电力调度数据网络的功能，采用 RTL8019AS 以太网控制器扩展了两路独立的网络接口。针对 RTL8019AS 在专用环境下应用的特点，通过分析RTL8019AS 的设计与配置方法，采用跳线方式定制了终端的网络接口电路方案，简化了电路设计。并对所扩展网络接口的功能和性能测试，网卡承载的通信业务运行正常，报文交互的吞吐能力也满足应用的需求。项目研究达到了电能量远方终端双网口通信的目的，并投入工程应用。%In order to make electric power remote terminal unit linked to dual node dispatching data network ,the RTL8019AS network card controllers were used to extend double isolated physical interface .The implementation and configuration methods of RTL 8019AS were stud-ied ,jumper mode was selected to make the net interface circuits for the unit ,and the circuit de-sign was simplified greatly .By testing function and performance of this network card ,the com-munication service carried by this card is normal ,and the throughput capacity of the packet al-so meets the needs of the application .The expected purpose is achieved ,and this card is put in-to engineering application .
