一种可变采样率数据采集方法与应用

A Data Acquisition Method with Variable Sampling Rate and Its Application

为了既能完整采集观测要素数据信息,又能降低功耗,根据观测要素的波动周期特征,用可变采样率方法进行数据采集,由预设定时器控制设备工作,降低了对设备电源的功率要求,解决了受供电能力制约的问题。实际应用表明,这为农业气象自动站的节能设计提供一个有效方法。

Aiming at collecting observation data entirely and efficiently and basing on the data＇ s wave period, data acquisition were conducted by using a method with variable sampling rate. Facing the limit of power supply , a timer was used to control the equipments. Practicalities provide agrometeorological automatic station with an energy conservation design.
