摘要
随着汽车智能化与便捷化需求的提升，传统手动操作车载设备（如车窗、空调、灯光等）的方式，在驾驶过程中易分散注意力，增加行车安全隐患，同时难以满足用户对高效、便捷驾乘体验的追求。因此，研发一种能通过语音或远程方式灵活控制车载设备的系统，对提升行车安全性与驾乘舒适度具有重要现实意义。
本设计提出一种基于 STM32F103C8T6 单片机的车载语音识别控制系统。系统通过 SU-03T 语音识别模块接收用户语音指令，可精准控制车窗与天窗（由舵机模拟开关动作）、照明灯、氛围灯、空调（由继电器实现通断控制）及雨刮器（由舵机模拟刮动动作）的运行状态；OLED 显示模块实时呈现车窗、天窗、照明灯、氛围灯、空调及雨刮器的当前开关状态，为用户提供直观的信息反馈；同时，系统通过 ESP8266-12F WiFi 模块与手机建立连接，用户可通过手机 APP 远程控制上述车载设备的开关，进一步拓展控制方式的灵活性。
该车载语音识别控制系统操作便捷、响应迅速，既能通过语音控制减少驾驶过程中的手动操作，降低安全风险，又能通过手机远程控制满足用户提前调节车内环境的需求，有效提升行车安全性与驾乘体验，为车载智能控制领域提供了实用、可靠的解决方案。

Design of Electronic Blood Pressure Monitor Based on Single Chip Microcomputer
Abstract
With the improvement of living standards and the enhancement of health awareness, monitoring blood pressure and heart rate has become an important part of people’s attention to their own health. For middle-aged and elderly people, abnormal fluctuations in blood pressure and heart rate, if not monitored and treated in a timely manner, may lead to serious health problems and even endanger their lives. Therefore, it is necessary to develop a device that can conveniently and accurately monitor blood pressure and heart rate.
This design proposes an electronic blood pressure monitor based on STM32F103C8T6 microcontroller. The main functions of the system include: detecting the current user’s diastolic and systolic blood pressure through the blood pressure detection module; Using a heart rate detection module to measure the current user’s heart rate; The user initiates the measurement by pressing a button; When abnormal heart rate or blood pressure is detected, the system will sound and light an alarm; Display measurement values through OLED; At the same time, the system stores the detected blood pressure through a storage module, which can hold up to 20 sets, and users can view them by pressing a button.
The function of this electronic blood pressure monitor is to provide people with a convenient and effective tool for monitoring blood pressure and heart rate. By timely monitoring and alerting, it can help people detect health hazards as early as possible, facilitate timely measures, ensure physical health, and improve quality of life.
