摘要
设计了一个实时多点温度监控系统。通过USB转串口连接上位机与下位机,利用数字温度传感器DS18B20采集多点环境温度,采用单片机AT89C52处理采集到的数据,控制1602LCD显示实时温度。当温度达到系统设置的报警值时蜂鸣器报警,单片机同时能将采集的温度通过USB串口实时传给上位机。
In this paper, a real-time temperature monitoring system was designed, in which the data were acquired by digital temperature sensor DSI8B20, processed by SCM AT89C52, and displayed by 1602 LCD. When the temperature reaches the set value, the buzzer will work, and the AT89C52 will transmit the collected temperature to PC through the USB port in real time.
