Traditional bus systems have problems such as relying on manual operation, delayed information updates, and single functions in terms of station announcements and information display, which are difficult to meet passengers demand for accurate travel information and are not conducive to the intelligent management of bus operations.​The bus system based on the STC12C5A60S2 microcontroller integrates DS18B20 temperature sensor, DS1302 clock module, TTS voice broadcast module, 3 independent buttons, LCD12864 display, two LED indicators, and GPS Beidou positioning module, etc., realizing the automatic monitoring of bus operation status and intelligent display of information. The core functions of the system include: real-time monitoring of the temperature inside the bus through DS18B20 and displaying it on the LCD12864; obtaining the current time with the help of DS1302 to provide a basis for time-related operation scheduling; using the TTS voice broadcast module to automatically broadcast station information when the vehicle arrives at a designated station, and it can also be triggered manually through buttons; 3 independent buttons are used for modifying time, manually broadcasting stations and function switching respectively; the LCD12864 display synchronously shows the time, the temperature inside the bus, the current station information and the longitude and latitude obtained by the GPS Beidou module; two LED indicators represent the up and down directions respectively, clearly indicating the driving direction of the vehicle.​The implementation of this system effectively improves the automation and intelligence level of bus operation, reduces errors caused by manual intervention, provides passengers with timely and accurate travel information, and also facilitates bus dispatching management. It has high practical application value and provides a reference for the research and development of similar intelligent bus equipment.​Keywords:STC12C5A60S2; Bus system; Sensor; Intelligent broadcast; Positioning; Information display​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 温度传感器选择2.1.3 时钟模块选择2.1.4 语音播报模块选择2.1.5 按键模块选择2.1.6 显示模块选择2.1.7 定位模块选择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 温度传感器电路3.3 时钟模块电路3.4 语音播报模块电路3.5 显示模块电路3.6 定位模块电路3.7 按键模块电路3.8 LED 指示模块电路第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 OLED显示流程设计4.5 温度检测模块子流程4.6 时钟模块子流程设计4.7 GPS模块子流程设计第 5 章 仿真测试5.1 整体仿真测试5.2 温度传感器功能测试5.3 时钟模块功能测试5.4 语音播报模块功能测试5.5 定位模块功能测试5.6 显示模块功能测试5.7 按键与 LED 指示功能测试第 6 章 实物测试6.1 整体实物测试6.2 温度传感器功能测试6.3 时钟模块功能测试6.4 语音播报模块功能测试6.5 定位模块功能测试6.6 显示模块功能测试6.7 按键与 LED 指示功能测试第 7 章 总结与展望7.1 总结7.2 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
