Abstract

The utility model relates to an automatic soil carbon dioxide breath tester, which comprises an infrared absorption sensor, a timing recorder and a computer. The infrared absorption sensor is connected with the timing recorder; the timing recorder is connected with the computer; a memory and a data reading module are arranged in the computer. The automatic soil carbon dioxide breath tester is characterized in that a sensor jacket is installed outside the infrared absorption sensor. The sensor jacket is provided with vents of which the diameter is 1-2mm, and the distance between the two adjacent vents is not smaller than 5mm. The automatic soil carbon dioxide breath tester disclosed by the utility model is concise in structure, low in cost, easy to carry, convenient to operate, and capable of improving the work efficiency.

Description

Soil carbon dioxide is breathed automatic analyzer

Technical field

The utility model relates to a kind of soil carbon dioxide and breathes automatic analyzer, can go deep into 5-10 cm layer of soil Accurate Measurement earth's surface carbon dioxide fluxes and automatically measure record carbon dioxide flux data in the no supervision situation at night in the open air.

Background technology

The main cause of Global climate change is that the content of carbon dioxide isothermal chamber gas in the atmosphere increases.And the main cause of this increase is excessive use fossil fuel and deforestation.The carbon dioxide source is dead plant, and the leaf that for example descends slowly and lightly autumn also has animal, bacterium and ocean.We just take animal and bacterium as example, produce 1,500 hundred million tons carbon dioxide their every year.

The temperature that climate change causes increases, sea level rise, extreme weather and climatic event take place frequently etc., and the natural ecosystem environment for human survival of unifying has been produced and has a strong impact on.The climate change problem has caused global extensive concern, becomes the significant problem that mankind nowadays society needs to be resolved hurrily.

Soil is carbon storehouse maximum in the terrestrial ecosystems, thereby and soil respiration is soil and the main path of atmosphere exchange CO2 participation global carbon, set up the important development trend that soil carbon monitoring of respiration network has become global carbon research.Soil carbon monitoring of respiration instrument is to be used at present monitoring maximum equipment used in the CO2 flux.

The CO2 determining instrument import of existing market account for very large proportion, price is high, is unfavorable for applying.

The utility model content

Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and provides a kind of soil carbon dioxide that can automatically measure and record soil layer and earth's surface CO2 flux in the situation at night that reaches to breathe automatic analyzer in the open air.

The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of soil carbon dioxide is breathed automatic analyzer, comprise infrared absorption sensor, clock meter, computing machine, the infrared absorption sensor is connected with clock meter, clock meter is connected with computing machine, be provided with storer and data read module in the computing machine, it is characterized in that infrared absorption sensor outside is equipped with the sensor overcoat.

Described sensor puts the air hole that is provided with 1-2 millimeters of diameters outward, and the spacing between the air hole is not less than 5 millimeters.

The utility model can be measured the CO2 flux in the unmanned situation automatically at night, and timing automatic is measured soil layer or earth's surface CO2 flux as required, and automatically is recorded in the storer of computing machine.

Have by day in people's the situation, can read and be input to by data read module and calculate in the computing machine or process.

The utility model compared with prior art has the following advantages:

The sensor overcoat has stopped the earth clogging sensor, and the air hole that the while sensor puts outward can contact again the air of outside, can and record in the soil layer or CO2 flux data on the earth's surface in the automatic mensuration in field at night;

Equipment is simple, and is cheap, carries easily, easy to operate.

Can solve the research work in the open-air especially understaffed situation at night.

Embodiment

Referring to Fig. 1, Fig. 2, the utility model embodiment soil carbon dioxide is breathed automatic analyzer and is comprised according to an infrared absorption sensor 1, clock meter 2, the computing machine 3 that principle installs that be directly proportional of carbon dioxide absorption in the special spectrum wave band, infrared absorption sensor 1 is connected with clock meter 2, clock meter 2 is connected with computing machine 3, be provided with storer 31 and data read module 32 in the computing machine 3, a sensor overcoat 4 that can go deep into 5-10 centimetres of soil layers has been installed in infrared absorption sensor 1 outside.Infrared absorption sensor 1, clock meter 2, computing machine 3 can adopt existing techniques in realizing, and computing machine 3 can be by the soil carbon dioxide flux of inner clock control timing acquiring infrared absorption sensor 1 mensuration.

Be covered with the air hole 5 of 1-2 millimeters of diameters on the sensor overcoat 4, the spacing between the air hole 5 is not less than 5 millimeters.

The utility model can be measured the CO2 flux in the unmanned situation automatically at night, and timing automatic is measured soil layer or earth's surface CO2 flux as required, and automatically is recorded in the storer 31 of computing machine 3.

Have by day in people's the situation, can read and be input in the computing machine 3 by data read module 32 and calculate or process.

The utility model compared with prior art has the following advantages:

Can night open-air automatically measure and the record soil layer in or CO2 flux data on the earth's surface;

Equipment is simple, and is cheap, carries easily, easy to operate.

Every simple deformation of the present utility model or equivalent transformation should be thought to fall into protection domain of the present utility model.
