Abstract
The utility model discloses a farmland carbon dioxide burst size detection device, including gas collection case, air intake valve, drain tap, bottom gas production net, concentration detection module, the concentration detection module includes the digital probe of carbon dioxide, control - radio frequency integration chip and power, and the output interface connection of carbon dioxide digit probe arrives the input interface of control - radio frequency integration chip, and the power links to each other with carbon dioxide digit probe and the integrated chip of control - radio frequency simultaneously. The utility model discloses a gas of farmland soil release is collected to vacuum gas collection case to carbon dioxide gas's in the gas that direct detection collected in the collecting box concentration has been got rid of the interference of external gas and has effectively been avoided the diffusion of carbon dioxide gas in to the air, therefore has had higher detection precision and an accuracy.
Description
Technical field
The utility model relates to agriculture test field, particularly relates to a kind of farmland carbon dioxide releasing amount pick-up unit.
Background technology
Due to root system of plant, microbial growth activity, agricultural land soil is enable to produce the carbon dioxide of some, these carbon dioxide directly will reflect plant and microbial growth and active situation, collect and will detect carbon dioxide releasing amount and have great importance in the active state of soil inside for analysis plant growth and microorganism.At present carry out relevant carbon dioxide collection for agricultural land soil and the equipment detected substantially also does not have, because the carbon dioxide diffusion of agricultural land soil release is very fast, there is very large defect in existing density of carbon dioxide gas checkout equipment in the accuracy detected.
Utility model content
The purpose of this utility model: provide a kind of farmland carbon dioxide releasing amount pick-up unit, can collect and detect the carbon dioxide of agricultural land soil release accurately and effectively.
The technical solution adopted in the utility model is:
A kind of farmland carbon dioxide releasing amount pick-up unit, comprise gas collection case, air intake valve, drain tap, bottom gas production net, concentration detection module, described concentration detection module comprises carbon dioxide digital probe, control-radio frequency integrated chip and power supply, the output interface of described carbon dioxide digital probe is connected to the input interface of control-radio frequency integrated chip, and described power supply is connected with control-radio frequency integrated chip with carbon dioxide digital probe simultaneously.
Preferably, described carbon dioxide digital probe inside have employed GE company of U.S. digital carbon dioxide sensor T6613.
Preferably, described control-radio frequency integrated chip have employed TI company chip CC2650F128RGZ.
The utility model adopts vacuum gas collecting box to collect the gas of agricultural land soil release, and the concentration of the carbon dioxide in the gas that direct-detection is collected in collecting box, eliminate the interference of ambient atmos and effectively prevent carbon dioxide to the diffusion in air, therefore there is higher accuracy of detection and accuracy.
Accompanying drawing explanation
Fig. 1 is the plane structure chart of the utility model farmland carbon dioxide releasing amount pick-up unit.
Fig. 2 is the schematic diagram of the utility model farmland carbon dioxide releasing amount pick-up unit.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing.
Refer to shown in Fig. 1 and Fig. 2, a kind of farmland carbon dioxide releasing amount pick-up unit, comprise gas collection case 1, air intake valve 2, drain tap 3, bottom gas production net 4, concentration detection module 5, described concentration detection module 5 comprises carbon dioxide digital probe 6, control-radio frequency integrated chip 7 and power supply 8, the output interface of described carbon dioxide digital probe 6 is connected to the input interface of control-radio frequency integrated chip 7, described power supply 8 simultaneously with carbon dioxide digital probe 6 with control-radio frequency integrated chip 7 is connected.
Described gas collection case 1 is initially vacuum state, by whole farmland carbon dioxide releasing amount pick-up unit is arranged on above soil, bottom gas production net 4 is made to be deep in agricultural land soil, then open air intake valve 2, the gas that agricultural land soil can be made to discharge enters into gas collection case 1 by air intake valve 2.Because gas collection case 1 inside is vacuum state, can spread rapidly after gas enters into gas collection case 1 inside, thus the carbon dioxide comprised in gas is uniformly distributed in gas collection case 1, described carbon dioxide digital probe 6 effectively can detect the density of carbon dioxide gas of whole gas collection case 1 inside, and concentration values is sent to control-radio frequency integrated chip 7, described control-radio frequency integrated chip 7 is in conjunction with the volumetric quantities of gas collection case 1, thus the burst size of agricultural land soil carbon dioxide can be calculated, simultaneously, can by density of carbon dioxide gas and burst size by wireless network transmissions on data acquisition computer, enable experimenter by data acquisition computer remote monitoring soil carbon dioxide air release situation.Can by gas collection case 1 vacuum state by described drain tap 3.
Preferably, described carbon dioxide digital probe 6 inside have employed GE company of U.S. digital carbon dioxide sensor T6613.
Preferably, described control-radio frequency integrated chip 7 have employed TI company chip CC2650F128RGZ.
In sum, the utility model adopts vacuum gas collecting box to collect the gas of agricultural land soil release, and the concentration of the carbon dioxide in the gas that direct-detection is collected in collecting box, eliminate the interference of ambient atmos and effectively prevent carbon dioxide to the diffusion in air, therefore there is higher accuracy of detection and accuracy.
