基于STM32的宠物自动喂食器系统设计

Design of automatic pet feeder system based on STM32

针对因人们长期外出无法及时喂养宠物的问题,提出一种利用远程控制技术的宠物自动喂食器系统设计方案。该喂食器以STM32单片机为核心控制OLED的显示及称重模块和舵机,实现了定时定量加食,并可按照用户设定的时间定时发出语音播报吸引宠物进食;利用ESP8266开发移动端APP对系统进行远程功能控制,用户可设置喂食时间、食物分量等参数,操作界面简单。经测试,该系统可以在室温环境下正常工作,称重误差能够控制在5%以内,满足宠物喂食的精度要求;该宠物自动喂食器硬件简单、运行成本低,可实现对宠物的自动定时定量喂食功能。

In view of the situation that people can't feed their pets in time when they go out for a long time,a design scheme of automatic pet feeder system by using the existing remote control technology was put forward.With STM32 single-chip microcomputer as the core,OLED display,weighing module and steering gear were controlled to achieve the timing and quantitative feeding of pet automatic feeders.According to the user set time,a voice announcement was make to attract pets to come to eat;using ESP8266 to develop APP mobile client for remote function control,the operation interface was simple,and users could set feeding time,food quantity and other parameters.Testing has showed that the system operates normally at room temperature,with weighing accuracy controlled within 0.5%,meeting the precision requirements for pet feeding.The automatic pet feeder features simple hardware,low operating costs,and could effectively provide pets with timed and measured feeding.
