Problems solved by technology

[0004] At present, the traditional irrigation methods are mostly based on farmers’ field experience, or even flood irrigation, which is time-consuming, laborious, poorly targeted, and easily leads to the leaching of inorganic nitrogen from the plant and layer, increasing the loss of crop nutrients, causing damage to plants and soil. It has brought immeasurable losses; traditional irrigation methods cannot adapt to the remote irrigation management of greenhouses and other related work realized in the agricultural Internet of Things environment

Embodiment 1

[0051] refer to Figure 1-6 , an intelligent irrigation controller based on the whole growth period of plants, which includes: an intelligent irrigation controller host and an intelligent irrigation controller shell;

[0052] The intelligent irrigation controller host includes: an ARM data processing core unit 20 , a communication unit 21 , a power management unit 22 , an irrigation management unit 23 and an irrigation control unit 24 . When it is working, input the prescription parameters related to the irrigation of the whole growth period of the plant into the touch screen system, such as the start time and end time of each growth period, the irrigation amount corresponding to different stages, the number of irrigation, the interval time, etc., and then start the automatic For the irrigation process, the system can automatically judge the growth cycle of the crops, follow the real-time data returned by the flow sensor, and control the start and stop of the solenoid valve ac...

Embodiment 2

[0062] An intelligent irrigation controller based on the whole growth period of plants is designed. By embedding the irrigation prescription parameters in the whole growth period of plants accumulated by experts for a long time into the controller, the irrigation amount can be precisely controlled to ensure the water supply of plants in different growth stages. At the same time, the waste of water resources is greatly reduced. The intelligent irrigation controller based on the whole growth period of the plant is used to accurately irrigate the spring crop cucumbers throughout the growth period, and the intelligent irrigation controller is placed on the wall of the ear room of the solar greenhouse through the hanging installation hole, and the electromagnetic The lead wires of the valve and the flowmeter are installed in the ear chamber through the line protection tube, and respectively introduced into the lead wire hole of the flow sensor of the controller and the lead wire hol...

Embodiment 3

[0064] An intelligent irrigation controller based on the whole growth period of plants manages the irrigation of cucumbers in spring crops.

[0065] Equipment installation and use steps:

[0066] 1. Place the intelligent irrigation controller on the wall of the solar greenhouse ear room through the hanging installation hole, and connect it with the solenoid valve and flow meter lead wires in the shed. The mains line is introduced through the power supply fixing hole and connected to the host circuit board. Turn on the power switch and start working after the device is initialized.

[0067] 2. Enter the irrigation mode selection interface on the touch screen, and select the irrigation mode of "timed time + water volume";

[0068] 3. Enter the variety selection interface on the touch screen, and select "variety 1 spring crop cucumber" (the device stores irrigation prescription parameters of 4 different varieties by default);

[0069]4. Enter the main interface, which is divide...

Abstract

The invention discloses an intelligent irrigation controller based on the whole growth period of plants and a using method. The intelligent irrigation controller comprises an intelligent irrigation controller host and an intelligent irrigation controller shell. The intelligent irrigation controller host comprises an ARM data processing core unit, a power management unit, a communication unit, an irrigation management unit and an irrigation control unit. The intelligent irrigation controller shell is made of a stainless steel material. According to the intelligent irrigation controller, a flow sensor connection interface and a solenoid valve control interface are designed so that an instrument can carry out irrigation according to a preset irrigation prescription in the whole growth period of plants; on-off of the solenoid valve is controlled according to collected flow data so that precise control over agricultural irrigation can be achieved. Water can be saved by 15% or above compared with that of a traditional irrigation mode; meanwhile, the yield and quality of harvested spring cucumbers can reach or even exceed the corresponding level of spring cucumbers planted in a traditional mode.

Description

technical field [0001] An intelligent irrigation controller based on the whole growth period of plants and its application method. Background technique [0002] In the 21st century, water resources are becoming a precious and scarce resource. The problem of water resources is not only a resource problem, but also a major strategic issue related to the sustainable development of the national economy and society and long-term stability. Lack of resources has always been one of the important factors restricting my country's economic and social development. At present, the city's facility planting industry has reached 600,000 mu, driving more than 300,000 farmers to employment. The high cost of manual management and the low utilization efficiency of resources such as water, fertilizer and medicine seriously restrict the sustainable development of facility planting. The application of advanced water-saving irrigation control technology to agricultural water-saving irrigation can...
