【dz-983】基于STM32单片机的宠物自动喂食器

基于 STM32 的智能宠物投喂系统

摘 要

随着宠物在家庭中的地位日益提升，宠物主人对宠物的日常照护需求也越来越高。宠物投喂作为日常照护中的重要环节，其智能化和自动化水平直接影响到宠物的健康和生活质量。本设计旨在通过单片机技术实现智能宠物投喂系统，以提供更加精准和便捷的宠物喂食体验。

本系统采用STM32F103C8T6作为核心控制器，通过DHT11传感器实时监测宠物生活环境的温湿度，确保宠物生活在适宜的环境中。通过称重模块测量食物重量，以实现精准的投喂控制。水位检测模块和红外避障模块协同工作，智能控制宠物的饮水需求，确保宠物随时获得清洁的饮用水。时钟模块则为系统提供了时间基准，用户可以根据宠物的饮食习惯设置投喂时间，系统会在设定的时间点自动开启投喂步进电机，监测到食物重量达到预设最大值时停止投喂，并通过语音提醒宠物进食。为了方便用户随时了解宠物的生活状况和投喂记录，系统还配备了显示屏，能够实时显示包括温湿度、食物重量、水位、投喂时间等在内的宠物生活参数信息。通过按键修正实时时间，设置各项参数的阈值，以满足不同宠物的个性化需求。

该智能宠物投喂系统的设计，不仅实现了宠物喂食的自动化和精准控制，提高了宠物的生活质量，还通过节能控制减少了能源消耗，体现了环保理念，为宠物主人提供了更加便捷和直观的宠物照护体验。

Abstract

With the increasing status of pets in the family, pet owners have a growing demand for daily care of their pets. Pet feeding is an important part of daily care, and its level of intelligence and automation directly affects the health and quality of life of pets. This design aims to implement an intelligent pet feeding system through microcontroller technology to provide a more accurate and convenient pet feeding experience.

This system uses STM32F103C8T6 as the core controller. Real time monitoring of temperature and humidity in pets' living environment through DHT11 sensors ensures that pets live in a suitable environment. Measure the weight of food through a weighing module to achieve precise feeding control. The water level detection module and infrared obstacle avoidance module work together to intelligently control pets' drinking water needs, ensuring that pets have access to clean drinking water at all times. The clock module provides a time reference for the system, and users can set the feeding time according to their pets' eating habits. The system will automatically turn on the feeding stepper motor at the set time point, stop feeding when the weight of the food reaches the preset maximum value, and remind the pet to eat through voice. In order to facilitate users to understand the living conditions and feeding records of pets at any time, the system is also equipped with a display screen, which can display real-time pet living parameter information including temperature and humidity, food weight, water level, feeding time, etc. Adjust real-time time by pressing buttons and set threshold values for various parameters to meet the personalized needs of different pets.

The design of this intelligent pet feeding system not only achieves automation and precise control of pet feeding, improving the quality of life of pets, but also reduces energy consumption through energy-saving control, reflecting environmental protection concepts and providing pet owners with a more convenient and intuitive pet care experience.
