Abstract

The present invention discloses an intelligent water-saving irrigation system based on plant organ microsize change detection. It is formed from sensor, conversion amplification circuit and chip microprocessor measuring control communication system. The sensor can be mounted and held on the typical leaf or fruit of tested plant, and the measuring signal outputted by sensor can be transferred into convertion amplification circuit, and amplified, then transferred into the microprocessor, and transferred into main control computer at regular time, according to the result obtained for processing and analyzing measured data the main control computer can define that the electroni switch of said irrigation system is switched on or not so as to implement closed loop control of irrigated plant.

Description

Technical field [0001] The invention relates to the field of water-saving irrigation and the technical field of sensor measurement and control, in particular to an intelligent water-saving irrigation system based on the detection of micro-scale changes of plant organs. Background technique [0002] The current irrigation system uses parameters such as soil humidity and environmental temperature as the control parameters of the irrigation system, not direct parameters, so the control accuracy is low, and the problem is that it causes a lot of waste of irrigation water resources. That is to say, in the soil-plant-atmosphere continuum system (SPAC), most of the previous work focused on formulating irrigation regimes or establishing irrigation systems based on soil moisture. Although controlled irrigation according to soil moisture has been widely used, there are still many insurmountable difficulties. On the one hand, the suitable soil moisture for different regions, plants, so...
