Embodiment 1

[0027] Such as Figure 1 to Figure 2 As shown, on the one hand, the embodiment of the present invention provides a kind of barometric altitude detecting device, is arranged on the unmanned aerial vehicle, comprises air pressure sensor 1, sensor protective cover 2 and conduit, and air pressure sensor 1 is sealed in sensor protective cover 2, and Together with the sensor protective cover 2, it is installed on the UAV; one end of the conduit communicates with the sensor protective cover 2, and the other end passes through the sensor protective cover 2 and extends upward.

[0028] Specifically, the barometric altitude detection device used in the drone provided by the present invention includes an air pressure sensor 1 , a sensor protective cover 2 and a conduit. During installation, first cover the sensor protective cover 2 on the air pressure sensor 1, so that the air pressure sensor 1 is sealed in the sensor protective cover 2, and then complete the communication between the co...

Embodiment 2

[0048] The only difference with Embodiment 1 is:

[0049] Such as image 3 As shown, in the barometric altitude detection device provided by the present embodiment, the conduit includes a second flexible pipe 7 and a hard pipe 8 that are all hollow inside, and the hard pipe 8 is detachably arranged on the frame of the drone. One end communicates with the sensor protective cover 2, and the other end extends from the sensor protective cover 2 and communicates with the hard tube 8. The nozzle position at the top of the hard tube 8 is not lower than the highest point of the blade of the drone.

[0050] In this embodiment, the conduit includes a hard pipe 8 and a second flexible pipe 7, wherein the second flexible pipe 7 is used to connect the hard pipe 8 and the sensor protection cover 2, and the installation method is similar to that in the first embodiment, that is, the frame There is a perforation for the second flexible pipe 7 to pass through, one end of the second flexible p...

Embodiment 3

[0058] The only difference with Embodiment 1 is:

[0059] In the barometric altitude detection device provided in this embodiment, the sensor protective cover includes a mounting seat with an accommodation space inside and an inverted bowl-shaped mouth, the air pressure sensor is located in the accommodation space of the mounting seat, and the connection between the mounting seat and the drone is sealed. .

[0060] Optionally, in this embodiment, the sensor protective cover adopts an inverted bowl-shaped mounting seat with accommodating space inside. The structure is sealed and connected so that the air pressure sensor is in a sealed environment, ensuring that the air pressure sensor will not be disturbed during the detection process.

[0061] According to the preference of the above technical solution, adhesive strips or foam are used at the connection between the installation seat and the installation structure to realize the sealed connection. Optionally, the sealing memb...

Abstract

The invention relates to the technical field of UAVs (unmanned aerial vehicles), in particular to a barometric height detection device and a UAV (unmanned aerial vehicle). The barometric height detection device is arranged on the UAV and comprises a barometric sensor, a sensor protecting cover and a guide pipe, wherein the barometric sensor is sealed in the sensor protecting cover; the barometricsensor and the sensor protecting cover are mounted on the UAV; one end of the guide pipe is communicated with the sensor protecting cover, the other end of the guide pipe penetrates out of the sensorprotecting cover and then extends upwards to be away from blades, so that an external environment where the barometric sensor is located can be effectively isolated from turbulent flow produced by blade rotating, disturbance of an unstable barometric pressure environment on the barometric sensor is avoided, and accurate detection for barometric height is guaranteed; besides, the barometric heightdetection device is simple in structure, reasonable in design, low in production cost and good in detection effect.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an air pressure altitude detection device and an unmanned aerial vehicle. Background technique [0002] During the flight of the UAV, the air pressure sensor is usually used to detect the real-time flight altitude of the UAV. Through this altitude feedback, the UAV is controlled to fly according to the set target altitude through the altitude PID. However, the output value of the air pressure sensor will drift and fluctuate to varying degrees due to the influence of its measurement environment. The following situations will occur during flight, for example: Situation 1. The manual flight altitude changes drastically and is not linear, and the altitude of the log record data is completely unacceptable. Use; Situation 2: Altitude-fixed mode flight will fluctuate up and down and be difficult to control. In serious cases, the phenomenon of rapid climbing or lowering...
