新型多功能电子称重系统设计与MCU控制-毕业设计详解

Based on the document "Design of weighing control System Based On MCU", this paper presents a new type of multifunctional electronic weighing system. The system uses the commonly used C51 series MCU STC89C52 as the main control chip. It can accurately measure the mass of the object to be weighed. After setting the unit price, the system can automatically calculate the total price and display the measurement results on the LCD screen. Additionally, the system also has an automatic alarm function for exceeding the range. Furthermore, the system has expanded functions such as an electronic perpetual calendar and an electronic thermometer, making it more practical. The paper discusses the background of the topic, the basis for determining the system scheme, the design of the specific hardware circuit, and the basic ideas of software programming. Finally, the test results of the system are analyzed. The key components of the system include the electronic weighing system, MCU, weighing sensor, A/D conversion, time and temperature functions, and human-computer interaction. In conclusion, the design of this weighing control system based on MCU provides an efficient and accurate solution for weighing applications in commercial trades. It demonstrates the integration of various functions into a single system, enhancing user convenience and practicality. The system's performance and functionality make it a valuable tool for businesses and industries that require precise and automated weighing processes.
