Research And Design Of Electric Energy Data Acquire Terminal Of Special Transformer

In order to meet the current power requirements of a modern marketing information management and development of energy information collection to ensure the timely, accurate and reliable, standardized information collection system construction of electric power, the state is about to release "DL/T698 Energy Information Collection and Management System" series of standards.According to the standards, this dissertation studies the design norms and performance requirements for electric energy data acquire terminal of special transformer, surveies the user's actual business requirements and functional requirements, designes the software and hardware systems of electric energy data acquire terminal of special transformer.Firstly, combined with the international advanced IEC62056 technical standards and domestic released DL/T698 communication protocol standards, designes the models of electric energy data acquire terminal of special transformer according to its special requirements of measurement, collection and transmission.Secondly, combined with engineering examples, from the functional requirements and performance demands detailedly discusses its system design. In the functional demand, it introduces the functional designs of electric energy data acquire terminal of special transformer from eight aspects such as data acquisition, data processing and data transmission. In performance demand, it introduces system performance specifications from ten aspects such as climate and atmospheric environmental conditions, mechanical impact, insulating performance requirements.Finally, based on the special transformer acquisition terminal model design and system function need analysis, the hardware and software architecture unit are studied and designed. The hardware unit includes CPU core processing modules, functions processing modules, power and ac sample module, wireless communication module (including GPRS and Ethernet), local maintenance and YX/YM module, LCD module. and defines the interface between. function board with other interface card unit. Software architecture includes four parts such as communication port, DL/T698 protocol stack, application process module, logic unit.This dissertation researches and designes the electric energy data acquire terminal of special transformer which has the characteristic of advanced software and hardware technology platform, strong anti-jamming ability, large storage capacity and diverse communication mode, high energy metering accuracy, easy maintenance. Its overall performance index is in a leading level in industry.
