摘要
本文提出一种利用DS18B20数字式温度传感器作为温度采集工具,利用单片机AT89C52对它进行控制,并且通过RS-485总线做远程传送将采集到的数据通过RS-232接口送入PC机测温系统的设计方法。
The article deals with the means of realizing a distance-data acquisition system integrated temperature sensor DSIB20 as its collector, and single chip computer AT89C52 as its which uses main controller. It makes a long-range conveyance by using RS-485 Bus to send the collected data to PC temperature-measuring system by RS-232 interface.
