Remote irrigation control method

Abstract

The invention discloses a remote irrigation control method, and belongs to the technical field of irrigation control systems. A humidity sensor, a controller, a power device and an irrigation device are arranged at each terminal node. The humidity sensors detect the soil humidity of the terminal nodes in real time, and the soil humidity is transmitted to a central processing unit through communication modules. The central processing unit generates the irrigation amount needed at the terminal nodes in real time according to the detected weather condition, the soil texture, the types of cultivated crops, and an evapotranspiration value changing curve stored in a data memorizer, and control instructions are issued to the controllers of the corresponding terminal nodes through the communication modules, and include the irrigation time and the irrigation water flow speed. The irrigation work can be automatically started in time according to the actual situation of the farmland, the irrigation accuracy and timeliness are guaranteed, delayed crop growth caused by manual carelessness is avoided, and human power is effectively saved.

Description

technical field [0001] The invention relates to a remote irrigation control method and belongs to the technical field of irrigation control systems. Background technique [0002] During the growth of crops, in order to ensure the growth and development of crops, it is necessary to irrigate the crops. When irrigating large-scale crops, it needs to invest a lot of manpower and material resources. [0003] The application number is 201310191289.5, and the patent application date of application on May 21, 2013 discloses an irrigation system, including: a motor, a switch, a power supply, a water pump and a sprinkler. The irrigation system also includes a controller, and the switch is simultaneously connected with the The controller, the power supply are electrically connected to the engine, the water pump is electrically connected to the engine and the power supply, and connected to the spray head. In one of the embodiments, the controller is used to regularly send a start sig...

Problems solved by technology

[0005] The traditional irrigation system is mainly done manually, the irrigation effect is not good, and it is easy to cause a lot of waste of resources

At present, the more common irrigation systems are mostly timing systems, and the timing and irrigation volume are pre-set. However, if it encounters rain or even floods, it will affect the growth of crops.
