【摘要】：电力线通信技术是将携带有数据的电信号调制到电力线上,使用供电电力线作为信道进行通信的方式,具有成本低、方便快捷和易于组网的特点。将电力线通信技术与嵌入式技术相结合构成的电力线通信系统,具有嵌入式系统的专用性、可靠性、应用领域广泛等特点,在电力远动系统中得到了广泛应用,是电力线通信技术研究的一个重要方向。本文主要研究可在电力系统通信主站和从站终端中运行的远动通信应用软件的设计与实现。在对电力远动通信协议和相关报文格式分析的基础上,论文通过UML建模,分析软件的主程序类关系以及总召唤、单命令遥控等应用功能的执行过程,并在Visual Studio 2010平台上完成了软件的界面设计和功能实现。软件的主界面分为四个部分:系统、网络设置、电力线设置和应用,其中实现了远动通信的应用功能的主要是应用界面及系统界面中的网络管理部分。应用界面中的应用功能部分是软件的核心,主要实现总召唤、单命令遥控召唤等远动通信规约中定义的应用功能的选择和参数设置,以及对应用功能执行过程的控制。除此之外,应用界面中的应用方式、统计方式、动态数据显示等部分分别实现了主从方式和从站地址的设置、应用功能报文的统计、收发报文的解析和动态显示功能。系统界面中的网络管理部分实现了在主站对各个从站当日收发报文的数量、时延和在线时间的统计。测试结果表明,本软件能够运行于与电力线通信嵌入式系统相连接的主站和从站终端设备中,实现总召唤、单命令遥控召唤等多个应用功能的正常执行,完成完整的远动通信过程。同时软件可以对通信过程进行动态显示和监督,并在主站进行各个从站通信状态的统计。
[Abstract]:The technology of power line communication is to modulate the electric signal with data to the power line, and use the power line as the channel to communicate, which has low cost. The power line communication system, which combines the power line communication technology with the embedded technology, has the characteristics of special purpose, reliability and wide application fields of the embedded system. It is widely used in electric power telecontrol system. This paper mainly studies the design and implementation of telecontrol communication application software which can be run in power system communication master station and slave station terminal. Based on the analysis of message format. Through the modeling of UML, this paper analyzes the main program class relationship of the software and the execution process of the application functions such as total call, single command remote control and so on. The main interface of the software is divided into four parts: system, network setting, power line setting and application. The application function of telecontrol communication is mainly the application interface and the network management part of the system interface. The application function part of the application interface is the core of the software, which mainly realizes the total call. The choice and parameter setting of the application function defined in the telecontrol communication protocol, such as single command remote control call, and the control of the execution process of the application function. In addition, the application mode and statistical method in the application interface. Dynamic data display and other parts of the master-slave mode and slave station address setting, application function message statistics. The network management part in the interface of the system realizes the statistics of the number, delay and online time of the received and received messages at each slave station in the main station. The test results show that the network management part in the interface of the system realizes the statistics of the number of packets received and received on the same day, the time delay and the online time. This software can run in the terminal equipment of master station and slave station connected with the embedded system of power line communication, and realize the normal execution of many application functions, such as total call, single command remote control call and so on. At the same time, the software can display and supervise the communication process dynamically, and statistics the communication status of each slave station in the master station.
