远程终端单元

对于实现层，建议对IEC61970中的远程终端单元（RTU）类进行扩展，并增加与远程设定和服务器相关的类。

For the implementation level , the extension to RTU model in IEC 61970 is inevitable , and a new model with respect to remote setting and server should also be added .

远程终端单元（RTU）是配电自动化系统中的重要设备，负责监控中心与工业现场之间数据采集、执行上传／下达命令。

Remote terminal unit ( RTU ) is an important device in charge of data acquisition , uploading and command executing between surveillance center of power distribution automation system .

该系统通过现场仪表设备进行现场控制和数据采集，通过RTU（RemoteTerminalUnits远程终端单元）存储数据信息并与中心监控站通信，利用GPRS远程数据传输接收或者发送数据。

In order to realizing field controlling and data acquisition through instrumentation , this system stores data information and communicates with the center monitor by RTU ( Remote Terminal Units ), as well as uses GPRS remote data transmission to receive and transmit data .

通过对系统总体功能的了解，对系统终端的硬件电路和软件进行了设计，包括智能电子式电能表、远程终端单元及通信模块。

The whole design includes that of smart electronic electric energy meter , remote terminal unit and communication module .
