Wherein, Morphology observation method aspect, patent " the vegetation growth state monitoring system based on computer vision and Internet of Things " (CN102564593A) discloses a kind of vegetation growth state monitoring system based on computer vision and Internet of Things, and P.Foucher etc. (2004) have studied the whole Form Development that plant under Water Stress Conditions is described under artificial vision identifies in paper " Morphological image analysis for the detection of water stress in potted forsythia. ".Involved by above two kinds of methods or system, form monitoring method is strictly limited to fixing condition as floristics etc.
Wherein, electrical signal detection method aspect, Bao Yidan etc. (2005) have studied plant hydropenia information and the Changing Pattern between plant leaf blade electrical characteristics and leaf water potential in paper " the plant hydropenia degree based on vane electrical characteristics and leaf water potential is studied ".But the magnitude of voltage that the method is measured is subject to the water of irrigating plant or the impact of nutrient culture media intermediate ion amount and inaccurate.
Wherein, soil moisture content detection method aspect, patent " a kind of plant water-depletion detection water applicator " (CN201174917Y) discloses a kind of plant water-depletion detection water applicator of the testing circuit based on resistance wire change in resistance.But this detection system is more difficult detects plant hydropenia situation in real time.
So the above-mentioned plant hydropenia detection method utilizing Morphology observation, electrical signal detection, soil moisture content to detect has when carrying out plant hydropenia and detecting the deficiency that floristics limits, accuracy rate is lower.
Utility model content
The utility model aims to provide a kind of plant hydropenia pick-up unit based on vibration information, the mode of being impacted plant leaf blade by gas carries out plant hydropenia detection, overcomes the problem that in detecting plant hydropenia in prior art, floristics limits, accuracy rate is lower.
For achieving the above object, the utility model is by the following technical solutions: a range finder module, an one-chip computer module, a relay, a solenoid valve, an air pump, an air induction hose, an air-out hose, a fixed support, a fixed bar, a computer and plnat monitoring software systems, and described plnat monitoring software systems comprise signal acquisition module, signal processing module, signal characteristic abstraction module, pattern recognition module and display module, wherein, fixed bar is fixed on fixed support, range finder module is fixed on fixed bar, range finder module is positioned at above plant leaf blade, range finder module is connected with one-chip computer module by electric wire, one-chip computer module is connected with computer USB mouth by data line, one-chip computer module is connected with relay incoming end by electric wire, relay output end is connected with solenoid valve by electric wire, air induction hose one end is connected to solenoid valve inlet end, the other end is connected on air pump, air-out hose one end is fixed on fixed support, the other end is connected to solenoid valve outlet side, computer USB mouth provides power supply for one-chip computer module and carries out data transmission with one-chip computer module, one-chip computer module drives relay to open by changing low and high level, Controlling solenoid valve conducting, pressurized air in air pump is blown by air induction hose and air-out hose hit plant leaf blade and make it vibrate, range finder module gathers this plant leaf blade vibration signal and is input to one-chip computer module, one-chip computer module is transferred to computer USB mouth by after this signal AD conversion, signal acquisition module gathers the plant leaf blade vibration signal of computer USB mouth, and pass through the signal processing module of plnat monitoring software systems, signal characteristic abstraction module, pattern recognition module processes, display module display is delivered to after pattern recognition module processes.
Compared with prior art, the beneficial effects of the utility model are as follows:
Existing plant hydropenia detection method, as by Morphology observation method, soil moisture content detection method and electrical signal detection method etc., although can carry out Non-Destructive Testing to plant moisture, has the deficiency that floristics limits, accuracy rate is lower.
The mode that the utility model impacts plant leaf blade by gas carries out plant hydropenia detection, relay is driven to open thus Controlling solenoid valve conducting by one-chip computer module, by signal processing module, plant leaf blade vibration signal is processed, plant leaf blade feature when different water is coerced is extracted by signal characteristic abstraction module, realize treating the prediction of measuring plants whether lack of water by pattern recognition module, the high precision Non-Destructive Testing to plant whether lack of water can be realized.
