TECHNICAL FIELD

[0001] The present application relates to the technical field of atmospheric measurement, in particular to an atmospheric measurement device. BACKGROUND

[0002] The atmospheric measurement device is an atmospheric pressure data acquisition and analysis equipment installed in an unmanned aerial vehicle or other aircraft. The equipment usually has one or more air pressure sensing channels. By detecting the air pressure distribution data of certain specific points on the surface of the aircraft, the flight height and speed of the aircraft can be obtained to provide assistance for flight navigation. The resonant cylinder pressure sensor is a commonly used core device for sensing air pressure changes in the atmospheric measurement device. The sensor usually consists of a sensor resonant cylinder body and a data preprocessing circuit. The atmospheric measurement device can analyze and calculate air pressure data by combining the pressure sensor with a dedicated information processing circuit, and output effective information that can be directly used.

[0003] With the increasing demand for longer flight time, longer flight range, lighter weight and other increasingly stringent targets of aircraft, the atmospheric measurement device is required to have a more compact and flexible structure, and a lighter structure design. However, there is no more compact, flexible and lightweight atmospheric measurement device in the prior art. SUMMARY

[0004] The present application aims to overcome the shortcomings of the prior art and provide an atmospheric measurement device that can solve the problems in the prior art.

[0005] The technical solution of the present application is an atmospheric measurement device, wherein the device comprises a shell and a plurality of modular resonant cylinder pressure sensors arranged in the shell. Each modular resonant cylinder pressure sensor comprises a resonant cylinder, an integrated rigid-flexible circuit board, a preprocessing calculation module and an air nozzle. The integrated rigid-flexible circuit board is movably wrapped outside the resonant cylinder and connected with the resonant cylinder. The preprocessing calculation module is connected with the integrated rigid-flexible circuit board. One end of the air nozzle is connected with the resonant cylinder, and the other end is connected with an atmospheric pipeline to be measured. Part of the plurality of modular resonant cylinder pressure sensors forms a first sensor array through a connecting piece, and the other part forms a second sensor array through a connecting piece. The first sensor array is connected with the shell through a lateral adapter block and an adapter support. The second sensor array is connected with the shell through a lateral adapter block and an adapter support. The shell has a closed and coherent irregular curved surface structure to conform to the shape of the plurality of modular resonant cylinder pressure sensors.

[0006] Preferably, the device further comprises a plurality of modular information processing circuits. Part of the plurality of modular information processing circuits is connected with the shell through a connecting piece, and the other part is installed on a circuit support through a connecting piece to form an information processing circuit assembly.

[0007] Preferably, the number of modular information processing circuits is the same as the number of modular resonant cylinder pressure sensors.

[0008] Preferably, the number of modular resonant cylinder pressure sensors is 5, the first sensor array includes 2 modular resonant cylinder pressure sensors, and the second sensor array includes 3 modular resonant cylinder pressure sensors.

[0009] Preferably, the information processing circuit assembly includes four modular information processing circuits.

[0010] Preferably, the connector is a stud.

[0011] The above technical solution, by setting up multiple resonant cylinder pressure sensors, can simultaneously monitor the atmospheric pressure at multiple different locations on the surface of the aircraft; by adopting a modular design, combined pressure sensor array, and conformal shell, the limited and irregular design space can be fully utilized to meet the product design requirements and improve the utilization rate of the aircraft's internal space.

[0019] Specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the following description, specific details are set forth for purposes of explanation and not limitation, in order to aid in a thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention may be practiced in other embodiments departing from these specific details.

[0020] It should be noted that, in order to avoid obscuring the invention with unnecessary details, only the device structure and / or processing steps closely related to the solution according to the invention are shown in the accompanying drawings, while other details that are not closely related to the invention are omitted.

[0021] like Figures 1-6 As shown, this embodiment of the invention provides an atmospheric measurement device, which includes a housing 5 and a plurality of modular resonant cylinder pressure sensors 8 disposed in the housing 5. Each modular resonant cylinder pressure sensor 8 includes a resonant cylinder 1, an integrated rigid-flexible circuit board 2, a preprocessing calculation module 3, and an air nozzle 4. The integrated rigid-flexible circuit board 2 is movably wound around the outside of the resonant cylinder 1 and connected to the resonant cylinder 1. The preprocessing calculation module 3 is connected to the integrated rigid-flexible circuit board 2. One end of the air nozzle 4 is connected to the resonant cylinder 1, and the other end is connected to the atmospheric pipeline to be measured. A portion of the plurality of modular resonant cylinder pressure sensors forms a first sensor array 12 through connectors 7, and another portion forms a second sensor array 14 through connectors 7. The first sensor array 12 is connected to the housing 5 through a lateral adapter block 6 and an adapter bracket 9. The second sensor array 14 is connected to the housing 5 through a lateral adapter block 6 and an adapter bracket 9. The housing 5 has a closed, continuous, irregular curved surface structure to conform to the shape of the plurality of modular resonant cylinder pressure sensors 8.

[0022] The above technical solution, by setting up multiple resonant cylinder pressure sensors, can simultaneously monitor the atmospheric pressure at multiple different locations on the surface of the aircraft; by adopting a modular design, combined pressure sensor array, and conformal shell, the limited and irregular design space can be fully utilized to meet the product design requirements and improve the utilization rate of the aircraft's internal space.

[0023] For example, the integrated rigid-flex circuit board 2 adopts a strip-shaped bendable structure.

[0024] According to one embodiment of the present invention, the device further includes a plurality of modular information processing circuits 10, a portion of which is connected to the housing 5 via connectors 7, and another portion is mounted on a circuit support 11 via connectors 7 to form an information processing circuit assembly 13.

[0025] Therefore, a modularly designed information processing circuit can be used to process and transmit the data collected by the sensors for use by the carrier flight control system.

[0026] According to one embodiment of the present invention, the number of modular information processing circuits is the same as the number of modular resonant cylinder pressure sensors 8.

[0027] In other words, a modular resonant cylinder pressure sensor is connected to a modular information processing circuit.

[0028] According to one embodiment of the present invention, the number of modular resonant cylinder pressure sensors 8 is 5, the first sensor array 12 includes 2 modular resonant cylinder pressure sensors 8, and the second sensor array 14 includes 3 modular resonant cylinder pressure sensors 8.

[0029] For example, five modular resonant cylinder pressure sensors can have different measurement ranges.

[0030] According to one embodiment of the present invention, the information processing circuit assembly 13 includes four modular information processing circuits 10.

[0031] According to one embodiment of the present invention, the connector 7 is a stud (or a screw or bolt).

[0032] The modular information processing circuits and modular resonant cylinder pressure sensors in this invention both adopt a modular, miniaturized, and specialized design approach. The functionality is broken down into five identical information processing circuits, each corresponding to one of the five pressure sensor modules. This effectively utilizes fragmented and irregular design space, avoiding wasted space. The atmospheric measurement device's shape is as follows: Figure 2 As shown ( Figure 2 (a) shows the front view, and (b) shows the back view. The shell adopts an irregular curved surface shape, which can make full use of the internal space of the aircraft. For example, the shell can adopt a thin-walled structure with a closed and continuous curved surface, which helps to reduce the structural weight of the product and ensures high structural rigidity. In addition, by designing combined pressure sensor arrays and information processing circuit components, the structural integration can be improved, facilitating system assembly and effectively improving the utilization rate of design space.

[0033] The atmospheric measuring device of the present invention will now be described with reference to examples.

[0034] like Figure 3 and Figure 4As shown, the first sensor array 12 consists of two modular resonant cylinder pressure sensors 8 connected as one unit by four studs 7, and fixed to the housing 5 by a lateral adapter block 6 and an adapter bracket 9. Similarly, the second sensor array 14 is installed in a basically the same way, except that it has one more modular resonant cylinder pressure sensor 8. To improve assembly manufacturability, four modular information processing circuits 10 can be mounted on a circuit bracket 11 by eight studs 7 to form an information processing circuit assembly 13, such as... Figure 5 As shown; a modular information processing circuit 10 is mounted on the housing via studs (e.g., Figure 3 As shown in (a) above, where, Figure 3 (a) represents the first sensor array, and (b) represents the second sensor array. Finally, the sensor arrays and circuit components are fastened to the product housing 5 using studs, and their internal layout is as follows. Figure 6 As shown, the product structure is relatively compact and the assembly process is reasonable, which can meet the design requirements.

[0035] As can be seen from the above embodiments, the atmospheric measurement device of the present invention adopts a miniaturized and modular dedicated information processing circuit design, a combined pressure sensor array, and a closed curved thin-walled structure, which can save design space and weight, and has the characteristics of compact structure and high integration.
