Traditional taxi meters have problems such as imprecise time differentiation, cumbersome unit price adjustment, and easy loss of data storage. They rely on manual intervention to set night surcharges, which can easily lead to metering disputes and are difficult to meet the needs of modern travel for transparent and automated billing.​The taxi meter design based on the STC89C52 microcontroller integrates DS1302 clock module, MX1508 motor driver module, KY-003 Hall detection module, AT24C02 storage module, buttons, LCD1602 display, and sound and light alarm devices, realizing the automation and intelligence of taxi billing. The core functions of the system include: obtaining real-time time through DS1302, automatically distinguishing between daytime (6:00-22:00) and nighttime (22:00-next day 6:00) periods, and implementing different pricing standards respectively (daytime starting price is 5 yuan for 3 kilometers, 2.5 yuan per kilometer beyond that; nighttime starting price is 8 yuan for 3 kilometers, 3 yuan per kilometer beyond that); detecting wheel speed through KY-003 Hall module to convert mileage, driving the motor through MX1508 to simulate driving status, and triggering sound and light alarm when the speed exceeds the limit; storing price parameters, total orders, total mileage and other data with AT24C02 to prevent loss due to power failure; supporting viewing daily total orders, total mileage, total amount and clearing records through buttons, and modifying time, setting maximum speed and adjusting price parameters; displaying real-time time, current speed, accumulated mileage, unit price and total amount through LCD1602.​The implementation of this system effectively improves the accuracy and intelligence level of taxi metering, reduces errors and disputes caused by manual intervention, ensures billing transparency, provides an efficient solution for taxi operation management, and also offers a reference for the research and development of similar on-board billing equipment, with high practical application value.​Keywords:STC89C52; Taxi meter; Hall detection; Intelligent billing; Data storage; Clock module目录第 1 章 绪论1.1 研究的目的及意义1.2 国内外发展情况1.3 本文主要研究内容第2章 设计思路与方案论证2.1 主要元器件选择2.1.1 主控芯片选择2.1.2 时钟模块选择2.1.3 电机驱动与测速模块选择2.1.4 存储模块选择2.1.5 按键模块选择2.1.6 显示模块选择2.1.7 声光报警模块选择2.2整体设计方案第 3 章 硬件设计3.1 主控电路模块3.2 时钟模块电路3.3 电机驱动与测速模块电路3.4 存储模块电路3.5 显示模块电路3.6 按键模块电路3.7 声光报警模块电路第4章 系统程序设计4.1 编程软件介绍4.2 系统主流程设计4.3 独立按键4.4 LCD1602液晶显示子流程4.5 速度检测子流程设计4.6 直流电机速度调节子流程设计第 5 章 实物测试5.1 整体实物测试5.2 时钟与计费功能测试5.3 里程与速度检测功能测试5.4 存储模块功能测试5.5 显示模块功能测试5.6 按键功能测试5.7 声光报警功能测试第 6 章 总结与展望6.1 总结6.2 展望致谢参考文献附录附录一原理图附录二PCB附录三主程序
