Embodiment 1

[0031] This embodiment discloses a method for estimating soil moisture in farmland, such as figure 1 shown, including the following steps:

[0032] Step 1: Set effective sampling points in the farmland in advance, and obtain the geographical location information and moisture data of effective sampling points.

[0033] Step 1.1 Set up M effective sampling points at the edge of the farmland, and set multiple effective sampling points at each edge. In order to ensure the accuracy of later calculations, the distance between adjacent effective sampling points at the edge of the farmland should not exceed 10 meters.

[0034] Step 1.2 Set multiple effective sampling points inside the farmland, wherein the number of effective sampling points inside the farmland is K, K=S / 20, and then rounded up, S is the plot area of ​​the farmland (m 2 )

[0035] Step 1.3 Acquire the moisture data of M+K effective sampling points in advance through the humidity sensor, forming a sequence {P 1 , P ...

Embodiment 2

[0065] This embodiment discloses a farmland soil moisture data estimation system, such as figure 2 shown, including:

[0066] Geographic location information collection module: used to collect the geographic location information of the target location in the farmland;

[0067] Straight-line distance acquisition module: used to obtain the straight-line distance between the target position and multiple preset effective sampling points according to the geographic location information of the target position;

[0068] Influence weight acquisition module: used to obtain the influence weight of each effective sampling point on the target position according to the obtained straight-line distance;

[0069] Current location moisture acquisition module: used to obtain the moisture data of the target location according to the moisture data of each effective sampling point obtained in advance and the influence weight of each effective sampling point on the target location.

Embodiment 3

[0071] This embodiment discloses an electronic device, including a memory, a processor, and a computer program stored on the memory and operable on the processor. When the processor executes the program, the farmland soil moisture content described in Embodiment 1 is realized. Data Estimation Methods.

Abstract

The invention relates to a farmland soil moisture content data estimation method and system. The method comprises the following steps: acquiring geographic position information of a target position in a farmland; obtaining linear distances between the target position and a plurality of preset effective sampling points according to the geographic position information of the target position; obtaining an influence weight of each effective sampling point on the target position according to the obtained linear distance; and obtaining the soil moisture data of the target position according to the soil moisture data of each effective sampling point obtained in advance and the influence weight of each effective sampling point on the target position, and therefore, the soil moisture at any position of the farmland can be rapidly estimated by adopting the method, and the requirement of intelligent variable operation of the farmland is met.

Description

technical field [0001] The invention relates to the technical field of soil moisture data collection, in particular to a method and system for estimating farmland moisture data. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The development of precision agriculture has far-reaching significance to agricultural production, and the monitoring of soil moisture is the key technical means to realize precision agriculture. Farmland soil moisture refers to the water content of the soil in the farmland, that is, humidity. Soil moisture information can be used to judge the growth status of crops, and has important guiding significance for farmland irrigation and disaster prediction. At the same time, carrying out variable operation according to the distribution of soil moisture, such as adjusting the depth of sowing, variable irrigation, etc., can effect...
