基于单片机的智能宠物喂食器系统设计
摘 要
随着人们生活节奏的加快，宠物主人常常因外出或忙碌而无法按时喂养宠物，智能宠物喂食器应运而生。本设计基于STM32F103C8T6单片机，开发了一款功能丰富的智能宠物喂食器系统，旨在为宠物提供精准、便捷的喂养服务，同时满足宠物主人远程监控与操作的需求。
该系统具备多种实用功能：通过时钟模块获取当前时间，并设置三个喂食时间点，每个时间点配有使能标志；称重模块用于实时监测食物重量，确保喂食量精准；水位监测模块可自动检测水位，当水位低于最小值时自动加水至最大值；喂食时间到时，步进电机驱动出食，并通过重量检测模块控制出食量，达到设定值后停止并触发声光报警提醒宠物进食；OLED显示屏用于实时显示测量数据，按键可切换界面进行投喂时间设置、投喂和加水操作；4G模块实现数据远程传输，宠物主人可通过手机端远程查看数据并设置投喂时间、控制喂水和喂食。
经过实际测试，该系统运行稳定，各功能模块协同工作良好。满足了设计要求，有效解决了宠物主人因忙碌而无法按时喂养宠物的问题，提高了宠物的生活质量，同时也为宠物主人提供了极大的便利。

Design of Intelligent Pet Feeding System Based on Single Chip Microcomputer
Abstract
With the acceleration of people’s pace of life, pet owners often cannot feed their pets on time due to going out or being busy, and smart pet feeders have emerged. This design is based on the STM32F103C8T6 microcontroller and develops a feature rich intelligent pet feeder system, aiming to provide precise and convenient feeding services for pets, while meeting the needs of pet owners for remote monitoring and operation.
The system has multiple practical functions: obtaining the current time through the clock module and setting three feeding time points, each time point is equipped with an enable flag; The weighing module is used for real-time monitoring of food weight to ensure accurate feeding amount; The water level monitoring module can automatically detect the water level, and when the water level is below the minimum value, it will automatically add water to the maximum value; When the feeding time is up, the stepper motor drives the feeding and controls the feeding amount through the weight detection module. When the set value is reached, it stops and triggers an audible and visual alarm to remind the pet to eat; OLED display screen is used for real-time display of measurement data, and buttons can switch the interface for feeding time setting, feeding, and water addition operations; The 4G module enables remote data transmission, allowing pet owners to remotely view data and set feeding times, control water and feeding through their mobile phones.
After actual testing, the system runs stably and all functional modules work well together. Satisfied the design requirements, effectively solved the problem of pet owners being unable to feed their pets on time due to busy schedules, improved the quality of life of pets, and also provided great convenience for pet owners.
