Embodiment Construction

[0039] The present invention is described below based on examples, but the present invention is not limited to these examples. In the following detailed description of the present invention, some specific details are described in detail. Those skilled in the art can fully understand the present invention without the description of these details. In order to avoid obscuring the essence of the present invention, the well-known methods, processes, and procedures are not described in detail. In addition, the drawings are not necessarily drawn to scale.

[0040] The following is an explanation of the terms involved in this article.

[0041] Total pressure: also known as stagnant pressure, it refers to the pressure when the airflow velocity and other stagnation reach zero, and it is the sum of static pressure and dynamic pressure in the airflow.

[0042] Static pressure: Static pressure refers to the pressure on the surface of an object when it is stationary or moving in a straight line...

Abstract

The embodiment of the invention provides an atmospheric data measuring device, and the device comprises a pipe body for receiving atmosphere; a sensor which is used for measuring the atmosphere to obtain first atmosphere data; a control module which is electrically connected with the sensor, comprises a digital signal port, and is used for obtaining second atmospheric data according to the first atmospheric data and transmitting the second atmospheric data through the digital signal port; a body which is fixedly connected with the pipe body and used for fixing the control module; and an aviation plug which is used for fixing the atmospheric data measuring device on external equipment. According to the atmospheric measurement device provided by the embodiment of the invention, an air entraining function and an atmospheric data measurement function are integrated together to form an integrated product. Remote digital signal transmission is used for replacing existing air guide pipe drainage, measurement errors caused by airflow remote transmission are avoided, the measurement precision can be greatly improved, and the weight of the whole system can be greatly reduced by replacing anair guide pipe with a cable.

Description

Technical field [0001] The invention relates to the field of aircraft, in particular to an atmospheric data measuring device and an aircraft Background technique [0002] Atmospheric data such as air pressure altitude and indicated airspeed during the flight of the aircraft are important parameters for the pilot or the aircraft's automatic driving system to control the safe flight of the aircraft. There are two types of traditional air data measurement systems: analog and digital: the analog air data measurement system introduces the air outside the aircraft into the air pressure altimeter, air pressure through the tube (also called pitot tube, total static pressure sensor, etc.) Analog devices such as speedometers deform the bellows in the barometric altimeter and airspeed meter through static or dynamic pressure, thereby driving the corresponding pointer to deflect to indicate the barometric altitude and airspeed; the digital air data measurement system also needs to pass throu...
