摘要
在采用温度传感器DS18B20与单片机AT89S52构成的单总线多点测温系统中,找出和更换损坏的传感器比较麻烦。文章在研究单片机多点测温系统的基础上,提出了解决该问题的一种硬件及软件设计方案。
In using the single bus multipoint temperature measurement system composed of the temperature sensor DS18B20 and the single-chip AT89S52, there is some difficulty in finding and replacing the damaged sensor. This paper describes the change of DS18B20 in this system. Meanwhile, it provides the hardware de- sign and software program of the problem-solving.
