摘要
随着社会对残障人士关怀的不断提升，为视障人群提供便捷、安全的生活用品对保障其生活独立性具有重要意义。传统的水杯在盲人使用时存在诸多不便，如无法知晓水温易造成烫伤、难以判断水位、操作依赖他人协助等问题，难以满足视障人群的日常饮水需求。
基于 STM32F103C8T6 单片机的语音交互式盲人智能水杯，整合了 SU-03T 语音识别模块、语音播报模块、显示模块、DS8B20 温度检测模块、水位监测模块、WiFi 模块、按键及执行设备（加热装置、制冷装置），实现了盲人饮水的便捷化、安全化与远程化。系统核心功能包括：通过 SU-03T 语音识别模块接收语音指令，控制水杯进行加热、制冷及播报当前水温水位；借助语音播报模块实时播报水温、水位情况以及加热、制冷的运行状态；通过显示模块展示水温、水位和加热制冷的开关状态，方便视力正常者协助查看；利用 DS8B20 温度检测模块精准检测水杯内水温；通过水位监测模块监测水位，当没水时自动禁止加热、制冷操作，并进行语音提醒；支持通过按键或手机端设置温度上下限，设置过程中通过语音播报反馈，确保盲人准确操作；通过 WiFi 模块将实时水温、水位数据传输至手机端，手机可远程设置水温阈值、控制加热及制冷继电器开关。
该系统的实现，有效提升了盲人使用水杯的便捷性与安全性，减少了对他人的依赖，同时通过 WiFi 模块拓展了远程监测与控制能力，为视障人群及照护者提供了更灵活的管理方式，为同类无障碍生活用品的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
With the continuous improvement of social care for people with disabilities, providing convenient and safe daily necessities for the visually impaired is of great significance for ensuring their independence in life. Traditional water cups have many inconveniences when used by the blind, such as the inability to know the water temperature which may cause scalds, difficulty in judging the water level, and reliance on others for operation, which are difficult to meet the daily drinking needs of the visually impaired.
The voice-interactive smart water cup for the blind based on the STM32F103C8T6 microcontroller integrates the SU-03T voice recognition module, voice broadcast module, display module, DS8B20 temperature detection module, water level monitoring module, WiFi module, buttons and executive devices (heating device, cooling device), realizing the convenience, safety and remote control of drinking water for the blind. The core functions of the system include: receiving voice commands through the SU-03T voice recognition module to control the water cup for heating, cooling and broadcasting the current water temperature and level; using the voice broadcast module to real-time broadcast the water temperature, water level, and the operating status of heating and cooling; displaying the water temperature, water level and the on-off status of heating and cooling through the display module, which is convenient for sighted people to check; using the DS8B20 temperature detection module to accurately detect the water temperature in the cup; monitoring the water level through the water level monitoring module, which automatically prohibits heating and cooling operations when there is no water and gives a voice reminder; supporting the setting of upper and lower temperature limits through buttons or mobile phones, with voice broadcast feedback during the setting process to ensure accurate operation by the blind; transmitting real-time water level and temperature data to the mobile phone through the WiFi module, enabling the mobile phone to set temperature thresholds and control the on-off of heating and cooling relays.
The implementation of this system effectively improves the convenience and safety of the blind using water cups, reduces reliance on others, and expands remote monitoring and control capabilities through the WiFi module, providing a more flexible management method for visually impaired people and their caregivers. It also provides a reference for the research and development of similar barrier-free daily necessities, with high practical application value.
