Abstract

The invention relates to an automatic gas sample collection station for monitoring greenhouse gas emission flux. The collection station comprises a power system, a master control system, an automatic static box, a water seal system, an automatic static box lifting system, a gas collection system, a gas injection system, a positioning system and a sample disc collection system. The main operating processes of the station comprises the following steps: supplying power through the power supply, sequentially controlling the covering of the box, the adding of water and sealing, collecting of gas, positioning of a sample bottle and injecting of gas through the master control system and recording environmental conditions during gas collection. After the gas sample is completely collected for the first time, the automatic static box is controlled to open, and sampling starts again when the next sampling time reaches. The master control system can transmit instructions through field key operation and also can be remotely or wirelessly controlled to operate or transmit a status report. The automatic gas sample collection station is mainly used for fully automatically sampling and monitoring greenhouse gases emitted from agriculture, forestry, grassland and natural ecosystem environments and also can be used for automatically sampling gases during atmospheric environmental monitoring.

Description

Technical field: [0001] The invention relates to automatic gas sample collection, in particular to an automatic sample collection device for monitoring gas emission flux in atmospheric environment conditions, mainly used for researching farmland, grassland and woodland (low forest) soil and corresponding growing plants The gas sample automatic collection device for monitoring the rate of greenhouse gas emission from the body into the atmosphere can also be used for automatic collection of gas samples in other gas environments. Background technique: [0002] Climate change is one of the most important issues that all human beings must face at present. It is mainly due to the overall trend of climate warming, which has an important impact on the entire earth's environment and all aspects of human life. Current scientific research shows that climate warming is mainly caused by the large amount of greenhouse gases emitted by human activities, which leads to the overall warming o...
