Description

Background
The vortex motion correlation instrument is an instrument applied to the fields of meteorology, hydrology and the like, and can directly measure physical quantities such as three-dimensional wind speed, wind direction, humidity, atmospheric pressure, carbon dioxide flux, sensible heat flux, latent heat flux and the like. In the prior art, an ultrasonic anemometer and a gas analyzer are generally used for carrying out combined observation on atmospheric turbulence, specifically, the ultrasonic anemometer is used for measuring horizontal wind speed and vertical wind speed, and the gas analyzer is used for measuring the material density of the atmosphere.
Referring to fig. 1, there is provided an installation diagram for observing atmospheric turbulence by using an ultrasonic anemometer and gas analysis in combination in the prior art (see patent document USD680455S), in order to ensure the accuracy of atmospheric turbulence analysis in an observation area, the ultrasonic anemometer and the gas analyzer are generally installed in a close distance range, and theoretically, it is known that the closer the distance of a measurement area between the ultrasonic anemometer and the gas analyzer is, the better.
However, when the distance between the ultrasonic anemometer and the gas analyzer is too close, they will interfere with each other, as shown in fig. 2, which is a schematic view of the gas flow for the joint observation situation and the theoretical non-interference situation, respectively, wherein the installation situation of the upper half in fig. 2 is the same as the installation situation shown in fig. 1, and the installation situation of the lower half in fig. 2 is the ideal non-interference situation.

Clearly this reduces the accuracy of the gas analysis of the ultrasonic anemometer inside the umbrella.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Before explaining the scheme of the invention, the vortex correlator is described below. The vortex correlator works based on the vortex covariance principle, and the analysis of the turbulent motion of the atmosphere by the vortex correlator belongs to a measurement method of micrometeorology, and the turbulent motion of the atmosphere can generate numerous small air masses, namely vortexes, as shown in fig. 3. And the vortex correlator utilizes a sensor capable of fast response to measure the characteristics of turbulent air mass between the atmosphere and the underlying surface, so as to obtain relevant data of material exchange and energy exchange.
In the prior art, a high-frequency three-dimensional ultrasonic anemoscope is usually adopted to observe horizontal wind speed and vertical wind speed, a gas analyzer is used to measure the material density of the atmosphere, and covariance operation is performed on the horizontal wind speed or the vertical wind speed measured by the high-frequency three-dimensional ultrasonic anemoscope and the measured material density of the atmosphere, so as to obtain the material flux of the atmosphere. The method is a standard method for directly measuring and calculating the flux, and is a key technology for measuring the substance and energy exchange flux of an ecological system.
Generally, a gas analyzer mainly includes two types, one of which is a gas sensor based on a TDLAS (Tunable Diode Laser Absorption Spectroscopy) technology, and the other of which is a gas sensor based on an NDIR (Non-dispersive Infrared) technology.
The vortex observation system built by the vortex correlator can measure the energy flux (namely sensible heat flux, latent heat flux and momentum flux) and the material flux (namely CO)2Or H2O) and some aerodynamic parameters, etc., which are mainly applied to the fields of boundary layer theoretical research, atmospheric diffusion, energy balance research, water and other material balance, etc.
Wherein, the material flux observation is suitable for various underlying surface environments such as forests, grasslands, farmlands, deserts, cities, water areas and the like, and is widely applied to the research on regional carbon and water circulation processes in the fields of Chinese academy, forest academy, meteorological bureau, ocean bureau and research of various departments; as an effective means for measuring and calculating the material and energy exchange information between an ecosystem and the atmosphere, the method provides an important data base for analyzing the interaction of the geosphere, the biosphere and the atmospheric space, and provides support for large-scale, long-term and continuous scientific research.
From the above description of the vortex correlator, it can be known that the vortex correlator plays a crucial role in the air quality analysis of the atmosphere, and therefore, in order to obtain reliable observation data and improve the accuracy of the air quality analysis of the atmosphere, the invention provides the vortex correlator.
The vortex motion correlator provided by the present invention will be described with reference to fig. 4 to 13.
The vortex motion correlator provided by the embodiment of the invention can comprise the following components: the ultrasonic diagnosis device comprises a supporting part 10 with an inner cavity, an extension pipe 20 and a fixing part, wherein two ends of the extension pipe 20 are respectively connected with the supporting part 10 and the fixing part, an ultrasonic transceiver and an optical transceiver are arranged on the fixing part, and the ultrasonic transceiver comprises an ultrasonic transmitter 41 arranged at one end of the fixing part and an ultrasonic receiver 42 arranged at the other end of the fixing part; the optical transceiver is arranged on the installation bottom surface of the ultrasonic transceiver, and the installation size of the optical transceiver does not exceed the installation size of the installation bottom surface of the ultrasonic transceiver;
the inner cavity of the supporting part 10 is provided with an integrated circuit board, the integrated circuit board passes through a cable of the through hole of the extension tube and is respectively connected with the ultrasonic transceiver and the optical transceiver electrically, the integrated circuit board is used for controlling the ultrasonic transceiver to transmit ultrasonic waves for wind speed measurement and also used for controlling the optical transceiver to transmit laser or infrared light for gas concentration analysis.
Therefore, in the vortex correlator provided by the invention, the optical transceiver is arranged on the installation bottom surface of the ultrasonic transceiver, and the installation size of the optical transceiver is not more than that of the ultrasonic transceiver, so that the influence on the atmospheric turbulent motion in the internal area of the fixed part is greatly reduced when the vortex correlator is used for observing the atmospheric turbulent motion, and the reliability of observation data and the accuracy of atmospheric turbulent motion analysis are improved.
In the embodiment of the invention, the circuit part on the integrated circuit board is divided into an ultrasonic speed measurement circuit for observing the wind speed of the target area and a gas analysis circuit for analyzing the concentration of the atmospheric turbulence motion of the target area according to functions. In addition, when the optical transceiver transmits and receives laser or infrared rays, the optical transceiver needs to be realized by two parts of an air circuit and a circuit together, and a connection part transmitter of the air circuit and the circuit converts the concentration change of the measured atmosphere into electric parameter change and converts the electric parameter change into voltage or current output through a corresponding circuit. The transmitter consists of two parts, including an optical system and a detector, and the main components include infrared radiation source, gas chamber, filter element and detector.
Because the circuit part and the optical device need to be placed in the inner cavity of the supporting component, the mounting size of the supporting component is usually larger, if the second umbrella-shaped support is directly connected with the supporting component, especially when the atmospheric turbulence is along the direction of the supporting component, the supporting component will certainly affect the gas analysis, therefore, the influence can be effectively reduced by arranging an extension pipe with smaller cross section size between the supporting component and the fixing component, thereby providing the reliability of the observation data and being beneficial to improving the accuracy degree of the atmospheric turbulence movement.
In one implementation, the cable passing through the extension tube through-hole may be an electrical cable or an optical fiber. It should be noted that the above mentioned cable or optical fiber is a preferred implementation of the present invention, and should not be construed as limiting the scope of the present invention.
In an embodiment of the present invention, referring to fig. 4 to 9, the fixing component is an integrated fixing frame, one end of the fixing frame 31 is provided with a first umbrella-shaped support 34, the other end of the fixing frame 31 is provided with a second umbrella-shaped support 32, the first umbrella-shaped support 34 and the second umbrella-shaped support 35 are symmetrically arranged, and have openings facing each other, the ultrasonic transmitter 41 is arranged on the first umbrella-shaped support 34, and the ultrasonic receiver 42 is arranged on the second umbrella-shaped support 35.
In one embodiment, the integrated fixing frame 31 may include three symmetrically distributed C-shaped arms. Preferably, the three C-shaped support arms form an included angle of 120 degrees between each two C-shaped support arms.
According to the geometrical principle, the regular structure has the best performance of bearing wind power. Of course, the embodiment of the present invention does not limit the specific shape of the fixing frame, and those skilled in the art can reasonably set the fixing frame according to the specific situation in the practical application, such as the installation place and the observation object.
In another embodiment of the present invention, referring to fig. 10 to 13, the fixing component is a pair of split first fixing seat 32 and second fixing seat 33, wherein a third umbrella-shaped support 36 is disposed on the first fixing seat 32, a fourth umbrella-shaped support 37 is disposed on the second fixing seat 33, the third umbrella-shaped support 36 and the fourth umbrella-shaped support 37 are symmetrically disposed, and their openings are opposite, the ultrasonic transmitter 41 is disposed on the third umbrella-shaped support 36, and the ultrasonic receiver 42 is disposed on the fourth umbrella-shaped support 37.
In practical applications, the wind speed is measured generally according to the principle that the propagation speed of sound waves in the atmosphere varies with the wind speed, and in the present invention, ultrasonic waves are used as a sound source of an ultrasonic transmitter in an ultrasonic transceiver device so as to be distinguished from ambient sound waves.
For example, a pair of ultrasonic transmitter and ultrasonic receiver is provided, the difference between the upwind and downwind travel times of the ultrasonic waves from the ultrasonic transmitter to the ultrasonic receiver is proportional to the wind speed component within the distance range, and the sum of the upwind and downwind travel times is related to the air temperature within the distance range. Therefore, the corresponding wind speed can be obtained by measuring the time difference and the time sum through the integrated circuit board.
Further, in a specific embodiment of the present invention, the ultrasound transceiver includes three ultrasound transmitters 41, and three ultrasound receivers 42 respectively paired with the three ultrasound transmitters 41; the three ultrasonic transmitters 41 are respectively installed at the ends of the umbrella ribs of the first umbrella-shaped support 34 or the third umbrella-shaped support 36; the three ultrasonic receivers 42 are attached to the ends of the umbrella ribs of the second umbrella-shaped support 35 or the fourth umbrella-shaped support 37, respectively. It can be understood that, generally, when performing ultrasonic observation, a three-dimensional observation mode is often adopted, specifically, three umbrella rib ends of the first umbrella-shaped support or the third umbrella-shaped support are respectively provided with an ultrasonic receiver, each ultrasonic receiver is used for receiving ultrasonic waves of one dimension, correspondingly, three umbrella rib ends of the second umbrella-shaped support or the fourth umbrella-shaped support are respectively provided with an ultrasonic transmitter, and each ultrasonic transmitter is used for transmitting ultrasonic waves to the ultrasonic receiver of the same dimension. That is, the first umbrella-shaped support and the second umbrella-shaped support are provided with three pairs of ultrasonic transceiving sensors which are used in a matched manner, and similarly, the third umbrella-shaped support and the fourth umbrella-shaped support are also provided with three pairs of ultrasonic transceiving sensors which are used in a matched manner.
It should be noted that the number of ultrasonic receivers and the number of ultrasonic transmitters mentioned in this implementation are a preferred arrangement provided by the embodiment of the present invention, and should not be understood as a limitation to the present invention, and those skilled in the art can make reasonable arrangements according to the specific situations in practical applications, such as adding or subtracting the respective ultrasonic receivers and ultrasonic transmitters.
In a preferred embodiment of the present invention, the optical transceiver device includes a laser transmitter 51, a laser receiver 52 and a laser reflector 53, the laser transmitter 51 and the laser receiver 52 are disposed on the first umbrella-shaped support 34 or the third umbrella-shaped support 36, and the laser reflector 53 is disposed on the second umbrella-shaped support 35 or the fourth umbrella-shaped support 37;
the laser transmitter 51 is configured to transmit laser light to the laser reflector 53, and the laser light is reflected by the laser reflector 53 and then received by the laser receiver 52.
It can be seen that the laser reflector is arranged on the second umbrella-shaped support, the laser emitted by the laser emitter arranged on the first umbrella-shaped support can be reflected to the laser receiver also arranged on the first umbrella-shaped support, so that the integrated circuit board can analyze the laser according to the receiving and sending time of the laser, and therefore when the vortex motion correlator provided by the embodiment is used for gas analysis, the interference of obstacles in an observation area formed by the openings of the first umbrella-shaped support and the second umbrella-shaped support can be completely eliminated, and the reliability of observation data and the accuracy of atmospheric analysis are effectively improved.
In another preferred embodiment of the present invention, the optical transceiver device comprises an infrared transmitter 54 and an infrared receiver 55, the infrared transmitter 54 is disposed on the first umbrella-shaped support 31, and the infrared receiver 55 is disposed on the second umbrella-shaped support 32;
the infrared transmitter 54 is configured to transmit infrared light to the infrared receiver 55.
It can be seen that the infrared receiver with smaller size is integrated and mounted on the second umbrella-shaped support, so that the interference of obstacles in an internal observation area formed by the opening between the first umbrella-shaped support and the second umbrella-shaped support or between the third umbrella-shaped support and the fourth umbrella-shaped support can be effectively reduced, and the reliability of observation data and the accuracy of atmospheric analysis are effectively improved.
In order to make the vortex correlator more suitable for installation and use in various application scenarios, the extension pipe 20 may be designed as a straight pipe (i.e. the extension pipe is "I" shaped) or an elbow pipe (i.e. the extension pipe is "L" shaped), please refer to fig. 4 to 9. In the present invention, as shown in fig. 10 to 13, the extension tube may be designed as a "Y" shape, which will be described later and will not be described herein again.
In a preferred implementation, the angle of the elbow may be set to 90 °, or a plurality of different angles may be set according to the actual installation space requirement.
The extension pipe of the present invention is a hollow pipe made of a hard material, and is preferably made of a moisture-proof and corrosion-proof insulating material.
In a preferred implementation, the inner cavity of the support member 10 may also be provided with a desiccant cartridge. The dryer is placed in the drying agent box, so that the drying degree of the space where the integrated circuit board is located can be effectively reduced, the integrated circuit board is never protected, and the service life is prolonged.
In practical application, besides the installation requirements of application scenarios, the influence of different air flow layer wind directions on the turbulent motion of the atmosphere needs to be considered. For example, in the observation of turbulent motion in the atmosphere, vertical wind velocity observation is very important. In practical application, the vortex-motion correlator can be transversely installed or longitudinally installed, wherein the transverse installation means that a connecting line of the first umbrella-shaped support and the second umbrella-shaped support is perpendicular to a horizontal wind direction when the vortex-motion correlator is installed, and the longitudinal installation means that the connecting line of the first umbrella-shaped support and the second umbrella-shaped support is perpendicular to a vertical wind direction when the vortex-motion correlator is installed.
In addition, according to test data, the accuracy of atmospheric turbulence motion observation can be effectively improved by changing the overall installation direction of the vortex motion correlator.
It should be noted that, in the installation process of the vortex correlation apparatus, the installation angle of the vortex correlation apparatus needs to be continuously debugged in combination with a specific application scenario. Of course, the present invention does not limit the specific angle value of the vortex motion correlator in practical application, and those skilled in the art need to make reasonable settings according to the specific situation in practical application.
In addition, in order to improve the installation stability of the vortex correlator, the vortex correlator can further comprise a base, and the supporting part 10 is arranged on the base.
