Problems solved by technology

However, the system requires a long equilibration time, 20 minutes per box, which may hinder the entry of rainwater and litter. At the same time, the internal environment of the flux box will change greatly due to the long closing time, especially the temperature rise. effect, which is not conducive to the determination of farmland ecosystems, grassland ecosystems, gaps in forestry ecosystems and other places with sufficient light (Naishen Liang, 2003)
In addition, the opening and closing of the flux box is controlled by the data collector, and the control ability is not enough. Each time, 6 boxes need to be closed together to cycle, which has great limitations in reflecting spatial variation.
The main problem and deficiency of the existing system is that the automatic control technology is backward, and it cannot be monitored rapidly and continuously at multiple locations around the clock, and the disturbance to the observed object is large, which affects the accuracy of the measurement.

Abstract

The invention provides a multi-channel automated chamber system, comprising an air compressor, an infrared CO2 analyser, a buffer, a drier, a filter, a flowmeter, an air pump, a data acquisition unit and a plurality of chambers, wherein, an air cylinder is arranged between the side wall and an upper cover of each chamber, the air compressor is connected with a multi-ported valve which has a plurality of branches, each branch is provided with an electromagnetic valve, each gas branch is connected with the air cylinder inside each chamber; each chamber is connected with one multi-ported valve by a gas branch provided with an electromagnetic valve and the gas branch is connected in sequence with the buffer, the drier, the filter, the flowmeter, the infrared CO2 analyzer and the air pump and then is connected with another multi-ported valve; each branch of the multi-ported valve is connected with each chamber, each branch is provided with an electromagnetic valve to form a circulating gas path; the infrared CO2 analyzer is connected with the data acquisition unit by a circuit; the electromagnetic valve which is connected with the air cylinder and controls the extension of the air cylinder and the electromagnetic valve which is arranged on the chamber and is used for controlling the circulating gas path are connected with a logic controller by the circuit. The system has the advantages that the reaction speed is high, the efficiency is high, the all-weather continuous and circular detection of a plurality of places is realized, and the influence on the target to be detected is small.

Description

technical field [0001] The invention relates to the field of terrestrial ecosystem monitoring, in particular to a method for monitoring CO between terrestrial ecosystems and the atmosphere. 2 Fully automatic multi-flux box system for exchange flux. Background technique [0002] Between terrestrial ecosystems and atmospheric CO 2 Exchange is the most important part of the global carbon cycle, and it is an important indicator for judging whether terrestrial ecosystems are "carbon sources" or "carbon sinks". Scientifically measure its CO 2 Exchange flux has always been one of the core tasks in the study of carbon cycle in terrestrial ecosystems. Improving the efficiency of observations and reducing the interference of observations on nature is the key to scientifically and accurately estimating CO2 between terrestrial ecosystems and the atmosphere on a regional and global scale. 2 The key to exchange volume. At present, it is better to use dynamic flux box infrared CO 2 T...
