Modularized plant photosynthetic detector

Abstract

The invention discloses a modularized plant photosynthetic detector, and particularly relates to the field of photosynthetic detection.The modularized plant photosynthetic detector comprises a control case and a detector body, the control case is arranged at one end of the detector body, a touch control integrated screen is arranged in the control case, a Dam data acquisition and analysis program, a field load network, a wireless air interface NBIot, an embedded computer IotGW, a sensor interface module IotNode and a mariaDB database are sequentially arranged in the touch control integrated screen, and a leaf chamber body is arranged on one side of the exterior of the control case. According to the invention, an embedded computer IotGW is used for uploading to the interior of a Dam data acquisition and analysis program, the Dam data acquisition and analysis program is used for analyzing and calculating, then experimental data is uploaded to a mariaDB database, the Dam data acquisition and analysis program can call out the experimental data stored in the mariaDB database at any time, and compared with the prior art, the experiment can be more perfected.

Description

technical field [0001] The invention relates to the technical field of photosynthesis instruments, and more specifically, the invention relates to a modular plant photosynthesis detector. Background technique [0002] At present, the gas circuit design of the photosynthetic instrument mainly includes two methods: open-circuit measurement method and closed-circuit measurement method. The open-circuit measurement is powered by an air pump, the air flows through the assimilation chamber and then empties, and the photosynthetic rate is calculated by measuring the CO2 concentration difference and ventilation in the air before and after entering the assimilation chamber; while the closed-circuit measurement is transmitted by an air pump, assimilation chamber and CO2 analyzer. Sensing equipment forms a loop, and the plants or leaves to be observed are enclosed in the assimilation chamber without any exchange with the outside air. The photosynthetic rate is calculated from the reduc...

AI Technical Summary

Problems solved by technology

The dual gas chamber design scheme of single gas source, double gas chamber, and double sensor effectively solves the defect that the single gas chamber cannot simultaneously study the gas source gas and the gas in the assimilation chamber, but due to the use of two sensors, it will cause errors in the consistency of the sensors. For the existing photosynthetic instrument, it can only transmit the information passively after receiving the information, and because the information received by the photosynthetic instrument itself is inaccurate, the efficiency of subsequent experiments is not high
