摘要
随着无障碍设施建设的推进和对特殊群体关怀的加强，为盲人提供安全、便捷的饮水辅助工具具有重要意义。传统水杯缺乏水温监测、自动加热和语音提示功能，盲人使用时易因水温过高烫伤或因水量不足影响使用，难以满足其安全饮水的需求。
基于 STM32F103C8T6 单片机的盲人智能水杯，整合了防水式 DS18B20 水温监测模块、YW-J 液位检测模块、SU-03T 语音识别模块、CN-TTS 语音播报模块、3 个独立按键、OLED 显示屏及加热装置，实现了盲人饮水的智能化辅助。系统核心功能包括：通过 DS18B20 实时监测水温，当水温低于最小值时自动启动加热，直至达到最大值；借助 YW-J 模块检测水量，无水时禁止加热；通过 SU-03T 模块播报当前水温和水量；支持设置定时喝水时间，到时由 CN-TTS 模块语音提醒；通过 3 个独立按键设置水温阈值和水量最小值，每步操作均有语音提示；通过 OLED 显示屏显示测量数据。
该系统的实现，有效提升了盲人饮水的安全性与便捷性，解决了传统水杯存在的安全隐患和操作不便问题，为盲人提供了贴心的饮水辅助，同时为同类无障碍智能设备的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
With the advancement of barrier-free facility construction and the strengthening of care for special groups, providing safe and convenient drinking water auxiliary tools for the blind is of great significance. Traditional water cups lack functions such as water temperature monitoring, automatic heating and voice prompts. When used by the blind, they are prone to scalding due to excessively high water temperature or insufficient water volume affecting use, which is difficult to meet their needs for safe drinking water.
The intelligent water cup for the blind based on the STM32F103C8T6 microcontroller integrates a waterproof DS18B20 water temperature monitoring module, YW-J liquid level detection module, SU-03T voice recognition module, CN-TTS voice broadcast module, 3 independent buttons, OLED display and heating device, realizing intelligent assistance for the blind to drink water. The core functions of the system include: real-time monitoring of water temperature through DS18B20, automatically starting heating when the water temperature is lower than the minimum value until it reaches the maximum value; using YW-J module to detect water volume, and prohibiting heating when there is no water; broadcasting the current water temperature and water volume through SU-03T module; supporting setting the timing for drinking water, and the CN-TTS module will give a voice reminder when the timing is up; setting the water temperature threshold and the minimum water volume through 3 independent buttons, with voice prompts for each operation when pressed; displaying measurement data through OLED display.
The implementation of this system effectively improves the safety and convenience of the blind’s drinking water, solves the potential safety hazards and operational inconveniences of traditional water cups, provides intimate drinking assistance for the blind, and also provides a reference for the research and development of similar barrier-free intelligent devices, with high practical application value.
