电力101规约详解和编程思想

【实例简介】
对101规约的详细介绍以及C++代码的编程思路和架构
Substation automation system is classified to function-oricntcd centralized automation system and the hierarchical object-oriented distributed automation system Used in the design of centralized substation automation system, from the back-plane, the total control unit(front-cnd) and telemetry, remote control unit with focus group scrccn Insta Power system communication protocol is the language of power system information transmission, IEC60870-5-101 as the statute of the ieC60870 protocol suite basic telecontrol tasks supporting standard", has become the main communication standards in scheduling grid sub-stations, known as the remote communication protocol of official international standards 101 protocol designed in this communication software is by visual Studio 2008 and SQL Sever 2008 development environment, the use of c language. Firstly, the frame format of the 101 protocol and data transmission is analyzed in detail, and according to the specific communication process 101 protocol to complete the dynamic model. Then, the design method using Socket programming, to achieve the establishment of the link layer, so that the back-plane can achieve data asynchronous transfer with the front-end. Then the article discusses in detail the application layer 101 protocol, the core of the Statute of 101 asdU object programming and how to send data frame pack, unpack the data frame of C# source code analysis. Finally, procedures and functions of interface further introduction Software, database synchronization with SQL Server, providing a clear and preservation of the form used to query the data of substation automation system, including telemetry, remote, remote connections, remote data, remote control window directly with the implementation of the remote control command at any point No., time synchronization with the APl function to achieve the access to SQL Server database, and analysis of the monitoring window displays the message, debugging results are correct Substation Automation System; 101 Protocol; Socket-based Programming ASDu Object 「2] 110kV 110kV 110kV MODEM 4. 57 IECTC57 IEC60870 IEC60870-5-11 IEC60870-5-2 2 IEC60870-5-33 IEC608705-44 IEC60870-5-4 ILC60870-5-101 IEC60870-5-102 IEC60870-5-103 IEC60870-5-104 IEC60870-5-101 IEC60870-5 IEC61334 ILC60870-5-101 ILC60870-5-104EC60870-5-102 101 Visual Studio 2008 SQL Server 2008 ASDU TCP/IP 110kV IEC60870 Visual Studio 2008 SQL Sever 2008 SQL aCd I TCP/IP TCP/IP Socket S rocket 101 ASDU Visual studio 2008 Web XML Web services Visual studio 2008 ASPnet Web Visual studio 2008 Visual studio 2008 Ⅴ isual studio2008 Ⅴ isual studio 2008 (LINQ sual studio 2008 NET Framework NET Framework 2.0 3.03.5 Visual studio 2008 Visual studio 2008 Web Windows vista Office 2007 SQL Server 2008 Windows Server 2008 Visual studio 2008 Web ASPNETAJAX Web 6 【实例截图】
