摘　　要：温度已成为生产、仓储及运输过程中的关键因素,对其的控制尤其关键。所设计的温度控制系统在传统模式的基础上新增远程短信通信功能,抛开传统感温电路模式,选用测量精度更高,且控制精度更高的单片机与DS18B20数字温度传感器相组合的方式进行温度采集,具备独立按键进行控制温度上下限的预设,采用LCD1602模块设计可视交互界面功能。在温度超出阈值报警时,EC600无线通信模块以发送短信的方式对超出温度阈值进行报警,蜂鸣器发出声音警报。该远程报警温度控制系统可有效防止温度升高后带来的高温窒息、花草缺氧等危险,具有广泛的应用范围。The temperature control system designed in this paper adds the function of long-distance short message communication on the basis of the traditional mode,abandons the traditional temperature sensing circuit mode,and selects the combination of single chip microcomputer with higher measurement accuracy and better control effect and DS18B20digital temperature sensor to measure the temperature.LCD1602 module with independent keys to control the preset upper and lower limits of internal temperature and visual functions as a visual interactive interface.When the temperature exceeds the threshold alarm,the ec600 wireless communication module sends a short message to alarm when the temperature ex-ceeds the threshold,and the buzzer sends an audible alarm.The remote alarm temperature control system can effectively prevent the dangers of high temperature asphyxia and hypoxia of flowers and plants after the temperature rise.
