说明：  本设计主要用数字式温度传感器DS18B20来采集外界温度，该设计硬件部分核心器件为89C52单片机。通过编写大量C语言程序来支撑单片机来实现温度接收、转换、存储和显示等，最终温度通过数码管显示出来。软件方面通过二个智能板通过RXD、TXD通信，一个智能板显示温度值，通过RXD发送到另一个智能板上并显示。
(The design of the main DS18B20 digital temperature sensor to capture the outside temperature, the design is part of the core hardware for the 89C52 single-chip devices. Through the preparation of a large number of C language program to support single-chip receiver to achieve the temperature, conversion, storage and display, the final temperature is displayed through the LED. Software through the adoption of two smart boards RXD, TXD communications, a smart board display temperature values sent through the RXD to another smart board and display.)
