Ecological data sensing, regulating and controlling method and system for kiwi fruit planting and irrigation

Abstract

The invention provides an ecological data sensing, regulating and controlling method and system for kiwi fruit planting irrigation, and the method comprises the steps: determining an irrigation group owner of each kiwi fruit planting region according to the preset position information of each irrigation device in each kiwi fruit planting region; a broadcast signaling is sent to each irrigation group owner, so that the irrigation device receiving the broadcast automatically joins in the irrigation group where the irrigation group owner closest to the irrigation device itself is located; receiving ecological data sensed by all irrigation devices in the irrigation group in which each irrigation group owner is located and reported by each irrigation group owner; judging whether a target irrigation device of which the sensed ecological data meets a preset irrigation mode switching condition exists or not; if yes, an irrigation mode switching instruction corresponding to the irrigation mode switching condition is issued to an irrigation group owner corresponding to the target irrigation device so as to correspondingly switch the irrigation mode of the target irrigation device. According to the invention, the difficulties of how to effectively arrange ecological sensing nodes and how to construct a reasonable communication architecture in ecological irrigation of kiwi fruits are solved.

Description

technical field [0001] The invention relates to the technical field of ecological data perception and regulation, in particular to a method and system for ecological data perception and regulation of kiwifruit planting and irrigation. Background technique [0002] Kiwifruit belongs to Actiniaceae, which not only has good edible value but also has rich medicinal value. Kiwifruit is distributed in Central South and Shaanxi, Sichuan, Jiangsu, Anhui, Zhejiang, Jiangxi, Fujian, Guizhou, Yunnan and other places. It has the effects of antipyretic, quenching thirst, invigorating the stomach and clearing stranguria. Indications: Fanre, diabetes, dry cough due to lung heat, dyspepsia, jaundice due to damp heat, shivering, hemorrhoids. [0003] Irrigation is particularly critical in the process of kiwifruit planting. Traditionally, it mainly relies on artificial sprinkling irrigation at regular and fixed points. However, this method is not only inefficient and labor-intensive, but als...

Problems solved by technology

[0004]However, there are still many shortcomings in the current automatic irrigation. Irrigation, which requires farmers to have rich planting experience. At the same time, this method is usually comprehensive irrigation, which cannot achieve differentiated and targeted irrigation. Due to the different ecological environments in different planting areas, or even different places in the same planting area, comprehensive irrigation It will cause some kiwifruit trees to decline in yield or even die due to over-irrigation or untimely irrigation

[0005] At present, although there are a few schemes that use sensors to sense ecological data and automatically turn on or off irrigation equipment through the controller, this scheme is due to the fact that each sensor is independently controlled When the number of sensors is too large, the controller is prone to downtime due to the impact of too many signal sources, and the sensor network will also quickly reach the life cycle due to excessive energy consumption, so this solution is currently only applicable to Small-scale planting areas, or scenes with a small number of sensors

In addition, in order to achieve a more comprehensive ecological data perception, it is generally required that the sensors be distributed relatively densely. In this case, interference between the sending and receiving signals between the sensors is likely to occur, resulting in some control commands issued by the controller being ineffective. response, eventually leading to failure of irrigation regulation
