Technical Field

[0002] An atmospheric measuring device is an atmospheric pressure data collection and analysis device installed inside an aircraft such as a drone. This type of device usually has one or more air pressure sensing channels. By detecting the air pressure distribution data at certain specific points on the surface of the aircraft, it obtains information such as the aircraft's flight altitude and speed, providing assistance for flight navigation. A resonant cylinder pressure sensor is a relatively common core component installed in an atmospheric measuring device that is sensitive to changes in air pressure. This type of sensor usually consists of a sensor resonant cylinder body and a data preprocessing circuit. By combining a pressure sensor with a dedicated information processing circuit, the atmospheric measuring device can analyze and calculate air pressure data and output effective information that can be directly used.

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

[0021] like Figure 1-6 As shown, an embodiment of the present invention provides an atmospheric measurement device, wherein the device includes a shell 5 and a plurality of modular resonant cylinder pressure sensors 8 arranged in the shell 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 can be movably wrapped 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 part of the plurality of modular resonant cylinder pressure sensors is formed into a first sensor array 12 through a connector 7, and the other part is formed into a second sensor array 14 through a connector 7, the first sensor array 12 is connected to the shell 5 through a lateral adapter block 6 and an adapter bracket 9, the second sensor array 14 is connected to the shell 5 through a lateral adapter block 6 and an adapter bracket 9, and the shell 5 has a closed, coherent, irregular curved surface structure to conform to the plurality of modular resonant cylinder pressure sensors 8.

[0022] Through the above technical solution, by setting up multiple resonant cylinder pressure sensors, the atmospheric pressure at multiple different positions on the surface of the aircraft can be monitored simultaneously; by adopting 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 internal space utilization of the aircraft.

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

[0025] Therefore, a modularly designed information processing circuit can be used to solve and send the data information collected by the sensor 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 .

Finally, the sensor array and circuit assembly are fastened to the product housing 5 by studs, and its internal layout is as follows: Figure 6 As shown, the product structure layout is relatively compact, the assembly process is reasonable, and it can meet the design requirements.
