When the fixing tube 7 has a tilting tendency, the pull rope 18 will be tightened, applying tension to the sleeve 14. A data processing device 19 is installed inside the drone body 1, and the data processing device 19 includes a signal receiving module 20 and a data calculation module 21. The signal receiving module 20 is signal-connected to the pressure sensor 12 and the position sensor 13, and the data calculation module 21 is signal-connected to the signal receiving module 20. The data calculation module 21 can calculate the tilt angle of the drone based on the pressure transmitted by the pressure sensor 12 and the position information transmitted by the position sensor 13.

[0037] Graph this table to obtain the function F(x) and enter this function algorithm into the data calculation module.

[0038] During the tilted flight shooting process of the drone, the fixed tube tilt angle θ, ie the drone tilt angle, can be calculated based on the pressure f applied to the pressure sensor 12 according to the function F(x), and θ=F(x)*f.

[0045] Furthermore, a method for using the UAV tilt monitoring device according to claims 1-7 comprises the following steps:

[0046] The first step is to unscrew the cover plate 8 before making this drone, fill half of the liquid into the mounting part 9, and then screw the cover plate 8 on for assembly;

[0047] In the second step, the wind turbine 2 is controlled to fly at an inclined angle by the flight control module 25, and the construction scene is photographed by the camera device 26;

[0048] In the third step, the drone body 1 tilts, driving the fixing tube 7 to tilt to one side. The pull rope 18 is tightened and pulls the ferrule 14 to slide on the fixing ring 10 until it is stable. The pressure sensor 12 is compressed and transmits the signal to the signal receiving module 20. Similarly, the position sensor 13 transmits the position information to the signal receiving module 20.

[0049] In the fourth step, the data calculation module 21 calculates the signal received by the signal receiving module 20, calculates the force and position information through a program, and displays the tilt angle on the display screen 24;

[0050] In the fifth step, the flight control module 25 is operated again to change the flight angle of the drone. The angle is calculated again using the above method. The construction site image information at different angles can be obtained through the camera device 26. The image information is then transmitted to the image recognition module 28 for recognition and then stored and identified in the cloud database 29.

[0052] The following is a specific implementation process of the present invention. The present invention sets a fixed cylinder 7 filled with liquid in advance. When the drone takes an oblique photo of the construction scene, the fixed cylinder 7 can be tilted with the drone. Since the fixed cylinder 7 is tilted, the pull rope 18 will be tightened, driving the sleeve 14 to slide on the surface of the fixed ring 10 until it is stable. The ball 16 will apply pressure to the pressure sensor 12 and the position sensor 13, and then transmit the force information and position data to the signal receiving module 20. The tilt angle of the drone can be calculated by the data calculation module 21 and displayed on the display screen 24 of the handheld controller 23, and then the tilt angle of the current picture is recorded. By using this method multiple times, the pictures taken by the drone at various tilt angles can be stored, which is convenient for building a real-life three-dimensional model and facilitating panoramic visualization management of construction.

[0053] In addition, the wind speed is monitored by the wind speed monitoring device 22, and the data can be transmitted to the data processing device 19 for processing, and then displayed on the display screen 24, so as to calculate the current wind speed of the drone and determine whether it can continue to fly; and the picture is captured by the camera device 26, and identified by the image recognition module 28, and the construction progress can be transmitted to the database 29 for recording. Moreover, if there are any illegal operations by construction workers on the construction site, they can be identified through the database 29, and then output by the voice output module 30, and the construction workers on site can be reminded through the broadcasting device 31.
