Design And Implement Of Intelligent Power Distribution Terminal Based On μC/OS-Ⅱ

For the measurement accuracy, reliability and validity of communication problems in the current distribution control terminal, using the new modular design concept, using high-precision energy measurement chip ATT7022B as the acquisition measurement module and using STC12C5A60S2 as data processing module, this thesis has designed and implemented an intelligent power distribution control terminal.Firstly, introducing the functional requirements of the system and theoretical basis, this paper focuses on analysis of the transmission mode of the Modbus communication protocol, providing a theoretical basis for the implementation of the system communication. And then it focuses on the hardware and the software design of the power distribution control terminal, hardware section describes the basic structure of the system and the various hardware circuit modules for achieving the system requirements. Basing on the system design and hardware design, it details the composition of the system software and the design process, achieving data storage of the system, analog reading, data processing, and communications functions. Finally, through the communication test of the system with the host, the system operates in a good condition. The design of the system achieves the desired design requirements, which has the features of high accuracy, high reliability and strong anti-interference ability of communication.
