"基于单片机的电量检测系统设计研究"

Introduction: The traditional power detection systems are facing more and more shortcomings as the power system capacity grows and the voltage level increases. They are unable to meet the needs of modern power grids for automation and digitalization. In response to this issue, this bachelor thesis focuses on the design of a power detection system based on a single chip microcontroller. Hardware System Design: The thesis first introduces the working principle and technical specifications of the WB series AC power sensors, and then proceeds to design the hardware system. This includes the design of the control circuit, module conversion section, keyboard input section, and LED display section. The characteristics of the electronic interfaces in ADC0809 and 74HC595 are also discussed, along with the analysis and research on the structure, principles, and functional divisions of the units. Suitable data conversion software is selected based on the analysis and research conducted. Software System Design: The thesis proposes a design scheme for the software system, with a focus on key issues such as the design of the A/D conversion program, the flow scheme of the main program and subprograms. Keywords include A/D converter, LED display, ADC0809, 74HC595, and single chip microcontroller. Conclusion: In conclusion, this bachelor thesis presents a comprehensive design of a power detection system based on a single chip microcontroller. By addressing the shortcomings of traditional power detection systems and utilizing modern technologies, this system aims to meet the evolving needs of modern power grids for automation and digitalization. This design not only enhances the accuracy and efficiency of power detection but also provides a solid foundation for the development of future power systems.
