Embodiment 1

[0032] see Figure 4 , a method for testing the uniformity of spray irrigation in an indoor windy environment, comprising the steps of:

[0033] S1. Wind force setting, aim the fan at the wind speed sensor, select the first-level wind, the second-level wind, the third-level wind and the fourth-level wind to blow the air on the wind speed sensor, and record the spraying distance of the nozzle at different wind speeds while keeping the water pressure constant , to detect the influence of wind speed on the spraying distance of the nozzle, which is beneficial to adjust the water pressure;

[0034] S2. Water pressure adjustment. Under the conditions of the first-level wind, the second-level wind, the third-level wind and the fourth-level wind, when the spraying distance of the nozzle is consistent, adjust the hydraulic control valve through the controller until the spraying distance is consistent, and record at the same time Corresponding water pressure, under the condition of ens...

Embodiment 2

[0044] A test method for a test system for spray irrigation uniformity in an indoor windy environment, comprising the following steps:

[0045] S1. Wind force setting, aim the fan at the wind speed sensor, select the first-level wind, the second-level wind, the third-level wind and the fourth-level wind to blow the air on the wind speed sensor, and record the spraying distance of the nozzle at different wind speeds while keeping the water pressure constant , to detect the influence of wind speed on the spraying distance of the nozzle, which is beneficial to adjust the water pressure;

[0046] S2. Water pressure adjustment. Under the conditions of the first-level wind, the second-level wind, the third-level wind and the fourth-level wind, when the spraying distance of the nozzle is consistent, adjust the hydraulic control valve through the controller until the spraying distance is consistent, and record at the same time Corresponding water pressure, under the condition of ensur...

Embodiment 3

[0058] A test method for a test system for spray irrigation uniformity in an indoor windy environment, comprising the following steps:

[0059] S1. Wind force setting, aim the fan at the wind speed sensor, select the first-level wind, the second-level wind, the third-level wind and the fourth-level wind to blow the air on the wind speed sensor, and record the spraying distance of the nozzle at different wind speeds while keeping the water pressure constant , to detect the influence of wind speed on the spraying distance of the nozzle, which is beneficial to adjust the water pressure;

[0060] S2. Water pressure adjustment. Under the conditions of the first-level wind, the second-level wind, the third-level wind and the fourth-level wind, when the spraying distance of the nozzle is consistent, adjust the hydraulic control valve through the controller until the spraying distance is consistent, and record at the same time Corresponding water pressure, under the condition of ensur...

Abstract

The invention discloses a test method for uniformity of sprinkling irrigation in an indoor windy environment, comprising the following steps: S1, wind power setting; S2, water pressure adjustment; andS3, wind direction detection. The test method for uniformity of sprinkling irrigation in the indoor windy environment of the present invention can perform water pressure adjustment of different nozzles according to preset wind power values and corresponding wind direction and hydraulic control valves according to different wind directions and wind speeds. The adjustment not only makes the sprinkling irrigation more uniform, but also achieves the purpose of saving water. The usage is safe and convenient.

Description

technical field [0001] The invention belongs to the technical field of sprinkler irrigation, in particular to a method for testing the uniformity of sprinkler irrigation in an indoor windy environment. Background technique [0002] With the continuous development of agricultural refinement, the requirements for the uniformity of sprinkler irrigation are gradually increasing, so as to reasonably meet the water demand of crops, save water as much as possible while ensuring the normal growth of crops, and realize the sustainable use of water resources . However, the outdoor wind speed and direction are unstable and uncontrollable, so it is difficult to accurately test the uniformity of sprinkling irrigation in an outdoor windy environment. [0003] For this reason, the present invention discloses a test system and method for the uniformity of spray irrigation in an indoor windy environment. The windy environment is simulated indoors, and the wind speed and wind direction are c...
