news 2026/6/28 15:01:20

摘要

导盲犬作为视障人士的重要辅助伙伴，其健康状况与饮食管理密切相关。传统的喂食方式依赖人工操作，存在喂食时间不规律、食物和水量把控不准、环境不适影响健康等问题，难以满足导盲犬科学养护的需求。

基于 STM32F103C8T6 单片机的导盲犬多功能喂食器，整合了 DHT11 温湿度传感器、HX711 称重模块、YW-J 水位监测模块、3 个独立按键、DS1302 时钟模块、OLED 显示模块、ESP8266 WiFi 模块及执行设备（风扇、加热器、喂食装置、加水装置），实现了导盲犬饲养的自动化监测与智能管理。系统核心功能包括：通过 DHT11 检测环境温湿度，温度过高时启动风扇，温度过低时启动加热装置，湿度过高时启动风扇；借助 HX711 称重模块获取食物重量，YW-J 水位监测模块监测水位；通过 3 个独立按键设置环境温湿度阈值、不同体型（大型、小型）导盲犬的食物重量和水位提醒值，并选择导盲犬体型；利用 DS1302 时钟模块获取时间，到达设定时间自动投喂，食物重量大于最大值时停止投喂，水位大于最大值时停止加水；通过 OLED 显示屏实时显示各项数据；通过 ESP8266 WiFi 模块远程显示环境温湿度、水量、食量、设置的重量和水位，以及远程控制风扇、加热装置、喂食喂水和选择导盲犬体型。

该系统的实现，有效提升了导盲犬饲养的自动化与智能化水平，保障了导盲犬的饮食规律和环境舒适，为导盲犬的科学养护提供了高效、可靠的解决方案，同时为同类宠物智能饲养设备的研发提供了参考，具有较高的实际应用价值。

ABSTRACT

Guide dogs, as important auxiliary partners for the visually impaired, have their health closely related to diet management. Traditional feeding methods rely on manual operation, with problems such as irregular feeding times, inaccurate control of food and water amounts, and uncomfortable environments affecting health, which are difficult to meet the needs of scientific care for guide dogs.

The multi-functional feeder for guide dogs based on the STM32F103C8T6 microcontroller integrates DHT11 temperature and humidity sensors, HX711 weighing modules, YW-J water level monitoring modules, 3 independent buttons, DS1302 clock modules, OLED display modules, ESP8266 WiFi modules, and executive devices (fans, heaters, feeding devices, water adding devices), realizing automatic monitoring and intelligent management of guide dog breeding. The core functions of the system include: detecting ambient temperature and humidity through DHT11, starting the fan when the temperature is too high, starting the heating device when the temperature is too low, and starting the fan when the humidity is too high; obtaining the weight of food through the HX711 weighing module and monitoring the water level through the YW-J water level monitoring module; setting environmental temperature and humidity thresholds, food weight and water level reminder values for guide dogs of different sizes (large and small) through 3 independent buttons, and selecting the size of the guide dog; obtaining time through the DS1302 clock module, automatically feeding when the set time is reached, stopping feeding when the food weight is greater than the maximum value, and stopping adding water when the water level is greater than the maximum value; real-time display of various data through the OLED display; remotely displaying environmental temperature and humidity, water amount, food amount, set weight and water level through the ESP8266 WiFi module, as well as remotely controlling the fan, heating device, feeding and watering, and selecting the size of the guide dog.

The implementation of this system effectively improves the automation and intelligence level of guide dog breeding, ensures the regular diet and comfortable environment of guide dogs, provides an efficient and reliable solution for the scientific care of guide dogs, and also offers a reference for the research and development of similar intelligent pet feeding equipment, with high practical application value.
