"基于单片机的多路输入电压表设计——宁夏大学机械工程学院2009届毕业设计研究"

The graduation project titled "Design of Multi-Channel Input Voltmeter based on Single-Chip Microcomputer" from the School of Mechanical Engineering at Ningxia University in 2009 focuses on the importance of voltage in industrial control applications. With the rapid development of microelectronics, computer technology, communication technology, and automation technology, traditional voltage measurement and control systems are facing challenges such as single-functionality, slow speed, low accuracy, and inability to store data long-term. These issues have made it difficult to meet the diverse and multifunctional needs of industrial automation and practical measurement work. Therefore, the project aims to address these challenges by developing a new multi-channel input voltmeter based on a single-chip microcomputer. The key components of the design include the voltage meter, A/D conversion, TLC1543, and programming. The use of the TLC1543 A/D converter enhances the accuracy and speed of voltage measurement, while the single-chip microcomputer provides the necessary computational power for real-time data processing. The programming aspect of the project involves writing code to control the measurement process and display the results on the screen. Overall, the project contributes to the advancement of voltage measurement and control systems by providing a more efficient and accurate solution for industrial applications. The design of the multi-channel input voltmeter based on the single-chip microcomputer not only meets the current requirements for detection speed, accuracy, and functionality but also lays the foundation for further research and development in the field of industrial automation and measurement technology.
