Water and fertilizer integrated automatic irrigation system based on Internet of Things

Abstract

The invention discloses a water and fertilizer integrated automatic irrigation system based on Internet of Things and relates to the technical field of irrigation systems. The automatic irrigation system comprises a water supply device, a management center, a plurality of soil humidity sensors and a division device, wherein the water supply device comprises a water pump, a water and fertilizer tank and a solid fertilizer tank, a water delivery pipe is fixed at a water outlet of the water pump, a transfer pump is fixed on the circumferential surface of the water and fertilizer tank, a first water pipe is communicated between the water delivery pipe and the transfer pump, a first electric flow valve is arranged on the first water pipe, a mixing box is fixed on the bottom surface of the solidfertilizer tank, and a stirring mechanism is fixed in the mixing box. Partition plates are arranged in a division pipe to divide the division pipe into multiple compartments, meanwhile, slide rails are arranged on the division pipe, sliding connecting parts are arranged, water can be injected to different compartments for division irrigation, and the problem that fertilizer is not put uniformly due to longer division pipes under fertilizer-carrying irrigation condition at present is solved.

Description

technical field [0001] The invention belongs to the technical field of irrigation systems, and in particular relates to an automatic irrigation system integrating water and fertilizer based on the Internet of Things. Background technique [0002] In the existing water and fertilizer automatic irrigation system, due to the large land area, it is often necessary to set up multiple channels on the shunt pipe for irrigation. However, the existing shunt pipes mostly use integrated pipes, and mostly use 1-3 irrigation channels. It is a working stage, and the irrigation is continued in a postponed manner after the irrigation is completed. [0003] When it is necessary to inject fertilizer into the irrigation water, the shunt pipe is relatively longer than the channel used for irrigation, and there will be irrigation water with fertilizer in the shunt pipe away from the irrigation channel, which will cause uneven fertilizer input during subsequent irrigation. However, the crops at ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a water and fertilizer integrated automatic irrigation system based on the Internet of Things. By setting a partition in the shunt pipe, the shunt pipe is set into multiple compartments, and at the same time, a slide rail is set on the shunt pipe, and a sliding type is set. The connecting piece can inject water into different compartments for split irrigation, which solves the problem of uneven fertilizer input caused by relatively long shunt pipes in the existing irrigation with fertilizer
