基于单片机的远程智能花卉培育系统设计(任务书,开题报告,论文14000字)
摘要
本次设计的花卉智能浇水系统包括当前环境的温湿度的获取与测量、以此为依据进行浇水以及光照补偿三个主要部分。其中，系统环境的温湿度的检测和显示以DHT11芯片为核心，将测量到的温湿度值送入STM32，最后再将这个值显示在LCD液晶屏幕上。智能浇水部分设计为手动和自动两个部分：自动部分是将温湿度传感器检测到的温湿度值，与系统初始设定的温湿度边界值进行比较，当检测值低于边界值时，STM32利用信号打开继电器，也就是进行开始浇水操作，当检测值高于边界最大值时，STM32利用信号关闭继电器，也就是进行停止浇水操作；手动部分是由SIM900A模块通过短信发送指令控制电子阀的打开与关；当光敏电阻检测到光照强度不足时，发送指令给单片机来打开光照进行补光，也可以通过通过SIM900A模块通过短信发送指令。本系统设计简单、性能优良，具有一定的实用性。

Design of Remote Intelligent Flower Cultivation System Based on Single Chip Microcomputer
ABSTRACT
The flower intelligent watering system designed this time includes the acquisition and measurement of the temperature and humidity of the current environment, and the main parts of watering and illumination compensation based on this. Among them, the temperature and humidity detection and display of the system environment is based on the DHT11 chip, and the measured temperature and humidity values are sent to the STM32, and finally this value is displayed on the LCD liquid crystal screen. The intelligent watering part is designed as two parts: manual and automatic: the automatic part is the temperature and humidity value detected by the temperature and humidity sensor, compared with the initial temperature and humidity boundary value of the system. When the detected value is lower than the boundary value, STM32 The signal is used to open the relay, that is, to start the watering operation. When the detected value is higher than the boundary maximum value, the STM32 uses the signal to turn off the relay, that is, to stop the watering operation; the manual part is controlled by the SIM900A module to send the electronic valve through the short message. When the photoresistor detects that the light intensity is insufficient, the command is sent to the MCU to turn on the light to fill the light, and the command can be sent through the SMS through the SIM900A module. The system has simple design, excellent performance and certain practicability.
