Embodiment 1

[0084] (1) Embodiment 1: Intelligent decision-making process

[0085] In this embodiment, soil moisture is used as an index to measure whether the crops are short of water. Through the soil moisture collected by the measurement and control module arranged in the No. 2 irrigation plot, the remote control center judges that the current field wheat is in a state of water shortage. At this time, the remote control center calculates that irrigation needs to be carried out within 24 hours, and the irrigation duration is 4 hours, and formulates the above irrigation content as an irrigation task. After waking up in the middle, the irrigation task will be synchronized to the No. 2 irrigation area measurement and control module. While the No. 2 irrigation plot controls the opening of the electronically controlled valve connected to it, the measurement and control module at the head controls the opening of the water pump to perform irrigation and fertilization. After the task is complet...

Embodiment 2

[0086] (2) Embodiment 2: Measurement and control module sleep strategy

[0087] Take the measurement and control module controlling the No. 2 irrigation plot as an example to illustrate the implementation of the sleep strategy. The measurement and control module of the No. 2 irrigation plot and the electronically controlled valves it controls are installed at the branch pipe inlet of the irrigation plot. The irrigation task formulated by the remote control center is to irrigate after 2 days. When the measurement and control module wakes up for the first time, it obtains the irrigation task from the remote control center. After the task is obtained, the measurement and control module enters a sleep state, and the microcontroller inside the measurement and control module enters a low power consumption state , the other circuits are turned off. After 12 hours, the microcontroller wakes up the measurement and control module, and actively reports to the remote control center throug...

Embodiment 3

[0088] (3) Embodiment 3: Management method of measurement and control module based on information identification

[0089] ① Example of the deployment process of the measurement and control module

[0090] First, use the user name and password of the drip irrigation system to log in to the remote control center through the terminal, that is, the smartphone in this example. Since the site where the measurement and control module is managed this time is in Tongzhou District, Beijing, the measurement and control module for soil moisture data to be configured in this example belongs to the 1,000-mu wheat intelligent drip irrigation system in Tongzhou, Beijing. Therefore, after logging in, first select the drip irrigation system through the mobile phone. After the selection is completed, the user selects the measurement and control module configuration function in the mobile phone, and uses the mobile phone to scan the QR code picture. The mobile phone reads the basic information o...

Abstract

Belonging to the technical field of high efficiency water-saving irrigation, the invention relates to a large-scale farmland wireless Internet of things intelligent drip irrigation system and method.The large-scale farmland wireless Internet of things intelligent drip irrigation system comprises a remote control center, a number of measurement and control modules, a field drip irrigation system and a terminal. The system and method provided by the invention realize all wireless control transmission, put forward consumption reduction and dormancy measures directed at the drip irrigation fieldmeasurement and control modules, at the same time the measurement and control modules are labeled with special information, and positioning of the measurement and control modules, reading, setting andother management operations can be completed through portable terminal reading. The system and method provided by the invention solving the problems of high power consumption, difficult layout and complex management in large-scale farmland intelligent drip irrigation systems, also simultaneously lower the building investment of large-scale farmland intelligent drip irrigation systems, and improvethe management efficiency.

Description

technical field [0001] The invention relates to the technical field of high-efficiency water-saving irrigation, in particular to a wireless Internet of Things intelligent drip irrigation system and method for large-scale farmland. Background technique [0002] The development of drip irrigation is an important way to achieve agricultural water saving, high yield, and high efficiency. It is of great significance to ensure the safe supply of agricultural products, drive farmers out of poverty, and promote agricultural modernization. The micro-irrigation area dominated by drip irrigation in my country has increased nearly 10 times in the past ten years, reaching 79.05 million mu in 2016, and my country has become the country with the largest drip irrigation area in the world. With the weakening of the rural labor force, the promulgation of land transfer policies, and the gradual development of large-scale and intensive agricultural production, drip irrigation technology is faci...
