摘 要
随着我国社会经济水平的快速发展，城市化的进程不断加速。我国国民生活水平不断提高，我国的宠物业也得到了飞速发展。由于城市生活的封闭性、个性化和人口老龄化等问题不断凸显。人民生活中休闲、消费和情感寄托方式也呈现出多样化发展。家庭宠物的饲养已经成为城市居民生活消遣的新方式。本设计具体完成基于STM32F103C8T6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、温湿度、光照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，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。本系统的设计和应用，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。

With the rapid development of our country’s social economy level, the process of urbanization is accelerating. With the continuous improvement of our national living standard, our pet industry has also developed rapidly. Due to the closed nature of urban life, personalized and aging population and other problems continue to highlight. The ways of leisure, consumption and emotional sustenance in people’s lives have also shown diversified development. The raising of family pets has become a new pastime for urban residents.This design completes the design and development of intelligent pet feeding control system based on STM32F103C8T6. The system takes single chip microcomputer as the control core, detects and collects the relevant parameters in real time through the sensor, realizes the collection and display function of physical weight, temperature and humidity, light and other information, and realizes the setting and adjustment function of timing feeding, weight and other parameters. In the design, when the feeding time arrives, the system automatically starts the motor to drop food, and the weight of the drop is detected and controlled. In addition to automatic operation control, the system also supports manual control mode, which is convenient for users to feed their pets.The design and application of this system can automatically complete the pet feeding operation under the condition of no one, ensure the regularity of pet diet, and solve the problem that the owner cannot reasonably feed the pet when he is not at home, and has great application prospects.
