Detection apparatus for pressure inside plant body

Abstract

The invention relates to a detection apparatus for a pressure inside a plant body. The detection apparatus comprises a measuring unit, a one-chip microcomputer, a DC-CD power converter, a USB interface and a computer, wherein the above-mentioned parts are successively connected. The USB interface unit includes a USB interface and a USB interface conversion circuit, wherein the USB interface and the USB interface conversion circuit are successively in bidirectional data connection; the USB interface and the computer are in bidirectional connection; and the USB interface respectively transmits a power supply provided by the computer to each part in the measuring unit and the one-chip microcomputer by the DC-CD power converter. The measuring unit detects a signal and transmits the signal to the one-chip microcomputer; and the one-chip microcomputer and the USB interface conversion circuit in the USB interface unit are in bidirectional data connection. According to the above-mentioned technical scheme provided in the invention, the detection apparatus for a pressure inside a plant body has advantages of simple structure, low cost and convenient usage; various information including an internal pressure of a plant, a temperature of the plant itself, an environmental temperature, an environmental humidity, and illuminance and the like can be detected conveniently and effectively.

Description

technical field [0001] The invention relates to a detection device, in particular to a pressure detection device in a plant. Background technique [0002] Plants convert the absorbed light energy into various organic substances through photosynthesis, which provides energy for the organisms on the earth, thereby ensuring the survival of various organisms. The strength of plant photosynthesis is closely related to its own growth status. The detection of water pressure in plants is like the blood pressure measurement of human body. Therefore, it is of great practical significance to study the growth status of plants. [0003] What is more advanced in the prior art is the plant water potential pressure chamber 3115 of the SEC of the United States, which is a portable model. It can reflect the overall water physiological status of plants and is widely used in research fields such as plant physiology, agronomy, irrigation, crop cultivation, and plant nutrition. When applying, ...

AI Technical Summary

Problems solved by technology

The existing technology can only test the water pressure in the plant body, but cannot detect the plant's own temperature, ambient temperature, ambient humidity and illuminance, and the plant must be placed in the sample room for detection, which is complicated to use.
