| 摘要: |
| 设计了常规远动终端(RTU)进行网络化改造方案.该方案通过在RTU外部增加串口/网络转换器将其串口转换成网络口接入调度数据网.介绍了网络化改造方案,网络化DNP3.0规约是基于0SI 7层协议模式,其中物理层、数据链路层、应用层为增强协议结构(EPA).物理层定义RS-232或RS-485界面,数据链路层定义信息格式,应用层定义规约的功能性.论述了站端网络接入配置(常规远动终端RTU的设置、串口/网络转换器的设置、设备的联接等).该方案无需对常规RTU的硬件及通信规约做任何修改,测试结果表明,该方案是可行的. |

| Abstract: |
| The retrofit scheme of RTU(Remote Terminal Units)communication network is presented,which connects RTU with dispatch data network via an added serial-port/Ethernet converter. The DNP3.0 protocol is based on the OSI 7-layer model and its physical layer,data link layer and application layer are of EPA(Enhanced Performance Architecture). The physical layer defines the interface of RS-232 or RS-485,the data link layer defines the format of the information and the application layer defines the functions. The con... |
