| Along with the online environmental monitoring system's development, the security and reliability becomes more and more important for the online environmental monitoring system running, according to which plenty of Intelligent IED are applied to substation. In order to obtain more real time information of online environmental monitoring system, somebody advance to build a communication substation for multi-protocol information conversion and a real time Database of the whole online environmental monitoring system based on PI Database technology. Now, lots of information which acquit by IED only be used at home and can't be transmitted to the Database, which lost much message, so we advance to build a new data acquisition system, which is named "Substation Data Import to PI Database System", the function of the new system is importing data of substation IED acquitted with real-time property or similarity real-time property to PI Database.The Communication Substation which discussed by this thesis is coming from the system hereinbefore. The main function of Communication Substation is data acquisition and Protocol conversion. Thesis introduces the status and peculiarity of the Communication Substation. The design on electrical of Communication conforms to multiple CPU cooperate working's principle. Thesis describes the collectivity whole frame of hardware and each of hardware's modules in detail. VxWorks OS is used by Communication Substation. The Software whole frame, data acquisition frame and interior Communication are interpreted particular, the thesis also simply describe the hardware driver, BSP development, Keyboard programmer and so on. Beside, the thesis has introduced how data is imported to PI database by IEC61850/103 protocol or OPC protocol. |
