Abstract

The invention relates to a water inlet protection device for a greenhouse gas analyzer and a control method thereof. The water inlet protection device is realized by intelligently switching the inlet passage of the greenhouse gas analyzer. The device is composed of a water inlet detection device, a passage conversion system, an alarm device and It is composed of drainage device and reset device. During use, after the water inflow detection device system detects water entering the intake pipe, the signal is sent to the channel switching system and the alarm device at the same time. After receiving the signal, the channel switching system opens the protection intake channel and closes the normal intake channel at the same time. , to prevent water from entering the analytical instrument and play a role in protecting the instrument. When the alarm device receives the water inflow signal, it starts the warning information and sends an alarm to the operator. After the operator clears the alarm, use the drainage device to drain the water in the intake pipe, and restore the original path through the reset device, then the instrument can continue to be used normally.

Description

technical field [0001] The invention relates to a protection device and method for a monitoring instrument, in particular to a water inflow protection device for a greenhouse gas analyzer and a control method thereof. Background technique [0002] The greenhouse gas analysis instrument is a commonly used instrument for measuring the greenhouse gas flux on the water surface by using the flux box method. When in use, a box with a top seal and a bottom that is open is placed on the surface of the water body. The analytical instrument is connected, and the gas in the box is pumped into the online analytical instrument through a vacuum pump to analyze and collect the carbon dioxide and methane that are emitted by the surface water body in a diffusion manner. The static box method has been widely used due to its low cost, good portability, and convenient connection with on-line analytical instruments. However, since the flux box is placed on the water surface, although the air in...
