由于生活节奏骤然加快，宠物的陪伴可以在一定程度上缓解孤独感，并以此填补情感空洞，随着智能产品需求的增加，用户对宠物用品提出了更高的要求，人们不仅满足于对喂食器的功能需求，更期望其能够满足内心的精神和情感需求。本课题通过相关理论，总结出相应的设计策略，为智能宠物喂食器的设计提供一定的指导和借鉴。本设计具体完成基于STC89C52的智能宠物喂食控制系统的设计开发。该系统以单片机为控制核心，通过传感器对相关参数进行实时检测和采集，实现实物重量、温度、投喂时间等信息的采集和显示功能，并实现定时投喂、重量等参数的设置和调整功能。在设计中，当喂食时间到达时，系统自动启动电机投放食物和水，并对投放重量进行检测和控制。除实现自动操作控制之外，本系统还支持手动控制模式，方便了用户喂食宠物。本系统功能的实现，能够在无人条件下自动完成宠物喂食操作，确保了宠物饮食的规律性，解决了主人不在家时无法合理喂养宠物的问题，具有很大的应用前景。

Abstract
As the pace of life suddenly accelerates, the companionship of pets can alleviate loneliness to a certain extent and fill the emotional void. With the increase in demand for intelligent products, users have put forward higher requirements for pet products. People are not only satisfied with the Functional requirement of feeders, but also expect them to meet their inner spiritual and emotional needs. This topic summarizes the corresponding design strategies through relevant theories, providing guidance and reference for the design of intelligent pet feeders.This design specifically completes the design and development of an intelligent pet feeding control system based on STC89C52. The system is controlled by a microcontroller as the core, and real-time detection and collection of relevant parameters are carried out through sensors, achieving the collection and display functions of physical weight, temperature, feeding time and other information, and achieving the setting and adjustment functions of timed feeding, weight and other parameters. In the design, when the feeding time arrives, the system automatically starts the motor to dispense food and water, and detects and controls the weight of the dispense. In addition to achieving automatic operation control, this system also supports manual control mode, making it convenient for users to feed their pets.The implementation of this system function can automatically complete pet feeding operations under unmanned conditions, ensuring the regularity of pet diet, and solving the problem of owners not being able to feed their pets reasonably when they are not at home. It has great application prospects.
