宠物智能喂食系统设计

Design of Intelligent Feeding System for Pets

摘要: 随着科技的发展和人们生活的提高，饲养宠物的人越来越多，而调查发现饲养宠物仅在喂食方面就需要花费大量精力和时间。为实现宠物的智能喂食，本设计以STM32F103C8T6单片机为核心、时钟、称重、喂食、监测、显示等模块，连接手机APP实现对宠物喂食的智能化管理。按键电路模块控制喂食时间与食物投放量。称重AD转换模块实时传输食物重量，红外线传感器判断宠物是否进食，OLED显示屏实现人机交互情况，实时显示宠物进食情况和食物投放量。该喂食器以STM32单片机为核心控制OLED的显示、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。通信接口JDY32蓝牙模块与手机完成连接后，可实现与手机APP连接，操作界面简单便捷，方便主人远程控制和操控。该智能宠物喂食器硬件简单、运行成本低，能循环执行用户下达的不同指令，解决了主人不在家宠物也能按时吃饭的难题。

Abstract: With the development of technology and the improvement of people’s lives, more and more people are keeping pets, and surveys have found that keeping pets requires a lot of energy and time just for feeding. To achieve intelligent feeding of pets, this design uses STM32F103C8T6 microcontroller as the core, clock, weighing, feeding, monitoring, display and other modules, connected to a mobile APP to achieve intelligent management of pet feeding. The button circuit module controls the feeding time and food dispensing amount. The weighing AD conversion module transmits the weight of food in real time, the infrared sensor determines whether the pet has eaten, and the OLED display screen realizes human-computer interaction, displaying the pet’s eating situation and food delivery amount in real time. The feeder uses STM32 microcontroller as the core to control the OLED display, weighing module, and servo, realizing timed and quantitative feeding, and can emit voice announcements at the time set by the user to attract pets to eat; Using ESP8266 to develop a mobile app for remote functional control of the system, users can set parameters such as feeding time and food portions, and the operation interface is simple. After the communication interface JDY32 Bluetooth module is connected to the mobile phone, it can be connected to the mobile APP. The operation interface is simple and convenient, making it easy for the owner to remotely control and manipulate. This intelligent pet feeder has simple hardware and low operating costs, and can execute different instructions issued by users in a loop, solving the problem of pets being able to eat on time even when their owners are not at home.
