摘要:
远程测控终端系统（RTU）是构成水文水资源监控系统的核心装置，不同的设备会有不同的应用层通信协议，从而造成信息解析和通信组网的困难。采用软件定义的方法，抽象主流RTU 应用层通信协议共性，形成统一的协议处理框架模型。将各种应用层通信协议算法按照框架模型进行模块化分割，其可执行代码用虚函数标记，保存在嵌入式CPU的flash 中，构成协议栈。根据配置指令加载及初始化RTU 通信系统，实现多种RTU 应用层通信协议的动态拼装与加载，在保持传感器数据采集协议与外部多种通信终端不变的情况下，采集数据从RTU 到中心站的高效传输。
Abstract:
Remote monitoring and control terminal system (RTU) is the core device which constitutes the hydrological and water resources monitoring system.There are different communication protocols of application layer with different devices, which causes the difficulty of information analysis and communication networking.Using the method of software definition, the mainstream RTU application layer communication protocol was abstracted, and a unified protocol processing framework model was formed.The application layer communication protocol algorithms were modularized based on the framework model.The executable codes were marked with virtual function and stored in the flash of the embedded CPU to form the protocol stack.According to the configuration instructions to load and initialize the RTU communication system, to achieve dynamic assembly and loading of a variety of RTU application layer communication protocol, to collect and transfer data efficiently from the RTU to the central station while maintaining the sensor data acquisition protocol and a variety of external communication terminal unchanged.
