基于单片机的智能宠物投喂系统的设计_毕业设计.docx

内容摘要 随着人们现在生活和工作的压力加大，相互间可以进行沟通交流的 次数减少，难以缓解压力和诉苦的人们，选择饲养宠物，但是由于工作 场所和公共地区的限制，平时只能将宠物寄放在家中，由于宠物也需要 进食，且如果不能得到合理的进食，会影响宠物的身体健康和情绪，导 致一些不可预计的事情发生。 针对于此，本设计研究一个可以实现智能投喂功能的宠物投喂系统。 解决了宠物主人出现外出旅行、过节或者在外工作的情况下，宠物不能 够自己寻找自己的粮食进食，避免了宠物进食时间不规律导致宠物身体 可能出现状况的问题。该系统由单片机+DS1302 时钟功能模块+称重功 能模块+继电器功能模块+LCD 显示功能模块+蜂鸣器+步进电机等进行 组合的设计，实现如下功能：宠物饲料放入容器当中，宠物主人通过设 定多个宠物进食时间点，时间一到，系统蜂鸣器发出声响，宠物听到这 个声响之后，知道该进食了。本设计主要研究如何设定进食时间点并发 出提醒声音。智能宠物投喂系统主要包括单片机控制、宠物自身手动开 关和声音提醒、设计倒计时。可以通过键盘设定宠物的进食时间，当依 次到达这进食时间，发光二极管会照明，蜂鸣器发出响声，食品会投放 出来，宠物便知道可以进行食用。通过LCD1602 显示出来宠物进食时间 的倒计时。通过单片机读取键盘设定的宠物进食时间，当达到设定的宠 物进食的时间，系统将进行自动投喂按指定重量进行食物投喂，当达到 指定重量后自动关闭。与此同时，系统还设置了手动控制按钮功能，饲 主通过教会宠物自主按下按钮，宠物在饿的时候可以自己进行按下进食。 关键词： 智能投喂定时控制宠物喂食重量控制 Abstract With the increasing pressure of peoples life and work, the number of times that people can communicate with each other is reduced. People who are difficult to relieve the pressure and complain choose to keep pets. However, due to the limitations of the workplace and public areas, pets can only be placed at home at ordinary times, and they also need to eat. If they cant get a reasonable diet, it will affect their health Kanghe mood leads to some unexpected things. In view of this, this design studies a pet feeding system which can realize intelligent feeding function. It solves the problem that pet owners cant find their own food to eat when they are traveling, having holidays or working outside, and avoids the problem that pets body may be in a state due to irregular feeding time. The system is designed by SCM + DS1302 clock function module + weighing function module + relay function module + LCD display function module + buzzer + stepper motor, etc. it realizes the following functions: pet feed is put into the container, pet owner sets multiple feeding time points, when the time arrives, the system buzzer makes a sound, and the pet knows after hearing the sound Its time for Tao to eat. This design mainly studies how to set the eating time
