基于单片机的智能宠物投食器控制系统设计与仿真
摘要：随着社会经济的快速发展和城市化进程的加快，城市公民家庭封闭和人口老龄化的形势突出，中国宠物产业也成为人们情感沉淀和休闲消费的必需品。传统的宠物投食器，只能够实现对食物的定点定时投食，本设计是在传统的定时投食器上新增了无线传输功能和液晶显示功能，可以使得主人能够实时的看到宠物的食量，保障了宠物的健康成长。
本设计是基于单片机的无线宠物智能投食器设计，设计分为两大部分，第一部分为宠物的食量检测和投食部分，组成包含了的单片机主控模块、重量检测模块、以及电机驱动及电机模块；第二部分为宠物的食量显示部分以及报警部分，组成包括单片机主控、液晶LCD1602显示、按键模块以及蜂鸣器报警模块，主从机的数据传输是通过无线nRF24L01模块，主要实现的功能就是实时检测宠物的食量，能够定时定点的进行实物补给，同时主人可以通过液晶实时检测宠物的余量，确保宠物能够健康成长。

Design of control system for pet feeder based on single chip microcomputer
Abstract：With the rapid development of social economy and the acceleration of urbanization process, the closure of urban households and the aging of population are becoming increasingly prominent. Based on the needs of people's emotional sustenance and leisure consumption, China's pet industry is also quietly rising. The traditional pet feeding device, can be achieved only designated for food timing feeding, the design is in the traditional timing feeding device on the new wireless transmission function and LCD display function, can make the master in real-time to see pet food intake, guarantee the healthy growth of pet.
This design is the design of wireless intelligent pet food investment based on single chip design is divided into two parts, the first part is the pet food detection and feeding part, which contains the microcontroller module, detection module, and the weight of the motor drive and motor module; the second part is the pet intake display part and an alarm part the main control module, composed of MCU, LCD display, LCD1602 button module, buzzer alarm, data transmission between the master and the slave is through the wireless nRF24L01 module, the amount of food mainly realize the function of real-time detection of pet, can real time designated supplies, while the owner can through the real-time detection of pet liquid crystal margin, ensure healthy pet growth.
