摘要
利用DALLAS公司推出的DS18B20智能温度传感器转换速度快,转换精度高的特点,将其应用于温度控制系统中。系统由DS18B20提供温度数字信号,采用凌阳十六位单片机SPCE061A进行温度控制,具有温度数字实时显示、语音播报以及PID算法控制等功能。介绍了系统的结构,硬件和软件设计,并给出了实现DS18B20时序控制的凌阳汇编程序。通过实验证明本系统可用于一般测温精度要求不高的场合,对其他实际的工业控制也具有一定的借鉴意义。
This paper introduces a temperature control system which provides a temperature digital signal by DS18B20 intelligent temperature sensor and controls the temperature by 16-bit signal-ship microcomputer SPCE061A of LingYang,showed system structure,hardware design and software design,and also gave the assembler about DS18B20 scheduling.This system has the functions of digital real-time display and voice broadcast as well as PID arithmetic control and so on.
