Problems solved by technology

[0004] However, shortening the sampling interval means that the amount of collected data is greatly increased, which will generate more redundant and repeated data, and will also lead to high energy consumption of monitoring instruments; on the contrary, expanding the sampling interval will lead to untimely data collection, Incomplete, lack of soil moisture data at critical moments, it is difficult to reflect the temporal and spatial variation characteristics of soil moisture in polar alpine regions

Abstract

The embodiment of the invention provides a soil moisture data collection method and device, and relates to the technical field of environment monitoring, and the method comprises the steps: controlling the sampling frequency of soil moisture data to be a sampling frequency corresponding to a time period according to the time period of a current moment; if the sudden weather event is monitored within the time period, the sampling frequency of the soil moisture data is increased to be the sampling frequency corresponding to the sudden weather event; and recovering the sampling frequency of the soil moisture data as the sampling frequency corresponding to the time period of the current moment when the sudden weather event is finished. According to the scheme, when weather changes, the sampling frequency can be expanded in time, then complete soil moisture data can be collected, the sampling frequency can be recovered at other times, and therefore data redundancy is avoided, and energy consumption of data collection is reduced.

Description

technical field [0001] The present application relates to the technical field of environmental monitoring, in particular, to a method and device for collecting soil moisture data. Background technique [0002] Soil moisture is an important observation parameter in global change, and its accurate measurement is a necessary condition for understanding and studying the global water cycle. In polar alpine regions (such as the Qinghai-Tibet Plateau), there are also characteristics of large temperature difference between day and night, variable climate, and frequent occurrence of extreme weather events. [0003] At present, the soil moisture monitoring instruments developed on the market collect soil moisture data regularly according to a fixed sampling frequency and a single sampling mode. Therefore, if the sampling data is required to be complete, the sampling interval can only be shortened. [0004] However, shortening the sampling interval means that the amount of collected ...
