摘　　要：介绍了工业上温度、压力数据采集的低功耗系统设计.温度信号转换采用AD7416温度传感器,压力信号转换采用16位的A/D转换器AD7705;采集的数据可以存储在存储器内,系统采集数据的时间间隔可以设置,在数据采集间隔期间系统进入极低功耗状态.最后探讨了PIC单片机低功耗系统的设计方法.This paper introduces the design of low-power system for industrial temperature and pressure data acquisition. In this system ,the temperature signal is processed by AD7416,and amplified pressure signal is processed by AD7705 ;the acquisited data is stored in the memory, the interval of data acquisition can be set by users. During the period of data acquisition the power of the system is rather low. The paper also presents the design of hardware and software of the system.
