Embodiment 1

[0026] Based on the above principles, the present embodiment provides a soil moisture monitoring method, comprising the following steps:

[0027] 1) The thermal infrared camera system and GPS module installed on the UAV flight device preset the route and photo time;

[0028] 2) The UAV flies according to the predetermined route, and the thermal infrared camera takes pictures according to the preset time, monitors the weather information, and stores the location information of the UAV's flight route, photos and weather information;

[0029] 3) Comparing and analyzing flight route location information, photo information and meteorological information to obtain soil moisture information.

[0030] The comparative analysis in the step 3) is calculated using the following formula:

[0031]

[0032] CWSI is the crop water stress index, Tc is the crop canopy temperature, Ta is the air temperature, D1 is the maximum temperature difference between the canopy and the air (generally t...

Description

technical field [0001] The invention relates to the technical field of agricultural information, in particular to a soil moisture monitoring method and system. Background technique [0002] Scientific irrigation is an important part of agricultural water saving. The establishment of a reasonable irrigation plan is the premise of scientific irrigation, and the diagnosis of crop water shortage is the basis for formulating a reasonable irrigation plan. The monitoring of soil moisture status has always been valued by people, especially with the aggravation of water shortage. Traditional observation methods include soil sampling and drying method, neutron moisture meter method, tensiometer method, etc., all of which are measured at points, and there are large sampling errors, and it is impossible to know the distribution of soil moisture in large areas of farmland. Assist in the scientific irrigation of farmland. Contents of the invention [0003] In order to solve the proble...
