Embodiment 2

[0048] like figure 2 As shown, the plant detection software system in the present invention includes a signal acquisition module, a signal processing module, a signal feature extraction module, a pattern recognition module and a display module.

Embodiment 3

[0050] A plant water shortage detection method based on vibration information: place the plant leaves under the ranging module, the air pump is powered on to work, the single-chip microcomputer module drives the relay to open, the control solenoid valve is turned on for 0.5 seconds, and the compressed air in the air pump is within 0.5 seconds. The air inlet hose is input to the solenoid valve and the air outlet hose is output to blow the surface of the plant leaves. At the same time, the ranging module collects the vibration signal of the plant leaves and inputs it to the single-chip microcomputer module. The single-chip microcomputer module converts the signal AD and transmits it to the USB port of the computer. The signal acquisition module collects the plant leaf vibration signal from the USB port of the computer, and transmits it to the signal processing module, the signal feature extraction module, and the pattern recognition module for processing, and the processing result...

Abstract

The invention discloses a plant water shortage detection device based on vibration information and a method thereof, which relate to the technical field of plant water shortage detection. The device comprises a distance measurement module, a singlechip microcomputer module, a relay, an electromagnetic valve, an air pump, an air inlet hose, an air outlet hose, a fixing bracket, a fixing rod, a computer and a plant detection software system. According to the device, the singlechip microcomputer module drives the relay to be turned on by changing high and low levels, the electromagnetic valve is controlled to be switched on, compressed air in the air pump blows plant leaves through the air inlet hose and the air outlet hose and enables the plant leaves to vibrate, the distance measurement module acquires a vibration signal of the plant leaves, and the vibration signal is subjected to AD conversion through the singlechip microcomputer module, transmitted to the computer and subjected to power spectrum processing and mode identification to realize the water shortage detection of plants; the device can be used for high-precision nondestructive detection of the plants in a water shortage detection process.

Description

technical field [0001] The invention relates to an agricultural moisture detection device and method, in particular to a plant water shortage detection device and method based on vibration information, belonging to the technical field of plant water shortage detection. Background technique [0002] The shortage of water resources is an important factor affecting the development of agriculture in our country. In factory agricultural production, in order to achieve high yield and high quality, it is necessary to improve the diagnosis and control technology of drought. Water is crucial to plant growth, but it is difficult to observe with the naked eye whether plants lack water. Existing methods for diagnosing water shortage in plants include morphological detection, soil water content detection, and electrical signal detection. [0003] Among them, in terms of morphological detection method, the patent "Plant Growth Monitoring System Based on Computer Vision and Internet of T...
