摘要
提出了采用插入ｓｌｅｅｐｙ状态，利用ＣＰＵ时间片操作来降低单片机系统负载效应并降低功耗的方法，已应用于某现场的无源流量计，实践证明该方法是有效的．文中对其工作原理进行了论证，并建立了实验电路及程序．
It′s well known that in micro processor system low power consumption and minimal loading effect is needed when battery or high resistant power source is used for the system working in field or some special circumstances. The method which can reduce the loading effect and power consumption of the micro processor system is put forward in the paper, by inserting sleepy state in the operation of the processor and making the processor work in different state according to the time slot. The method has been successfully used in a passive flowmeter. The principle is demonstrated based on the result of the experimental circuit and the program in the paper.〖HJ1〗 〖HJ〗
