摘　　要：以青海盐湖数据采集系统为实例讨论了用于野外环境条件下仪器仪表的低功耗设计方法。仪器以80C31单片机为核心，全部使用CMOS器件，采用分块间断供电方式和使用液晶显示器等多种方法使数据采集系统仪器功耗降到常供电电流仅95μA。The methods designing intelligent instrumentsused in fieldwork are discussed. The salt lakes Data Acquisition System (DAS) is used as designing examples. Specially. low power consumption is studied. The microcontroller80C31 is employed as CPU and low temperature CMoS ICsare selected for all circuits. For lower consumption. the system is partitioned and discontinuously powered. and liquidcrystal display with some other ways are used.
