Specifically, in the initial state, the sliding shaft 23 contacts with the right end of the second sliding groove 22, and the stage structure 3 is located on the left side of the wind measuring plate 24. The working principle of the invention comprises the following steps:

step S101, the controller controls the first electromagnet 25 to be electrified and detects whether pressure information detected by each pressure sensor is received in real time, wherein a plane formed by each first cross bar 31 and a central shaft of the second chute 22 is a wind measuring surface, an included angle between the wind measuring surface and a door window is a first included angle, an included angle between the wind measuring plate 24 and the door window is a second included angle, under the action of wind power, the wind measuring plate 24 rotates towards a direction away from the door window, the first cross bars 31 in the hierarchical structure 3 are numbered according to a sequence from right to left, first included angles corresponding to 1 to N first cross bars 31 from right to left are sequentially the 1 to N first included angles, the 1 to N first included angles are gradually increased, pressure sensors arranged on the 1 to N first cross bars 31 are sequentially the 1 to N pressure sensors, and a first connecting rod correspondingly connected with the right end of the ith first cross bar 31 is the ith first connecting rod, i is an integer greater than 0 and less than or equal to N, which represents the number of the first rails 31. When the second included angle of the wind measuring plate is equal to the ith first included angle, the detected ventilation amount is equal to the first unit ventilation amount i, namely, the wind measuring plate moves one first cross rod 31 leftwards when detecting that the total ventilation amount is increased by the first unit ventilation amount, and at the moment, the lengths of the first cross rods 31 can be equal.

Step S102, setting the anemometer plate 24 to be in butt joint with the ith first connecting rod 32 currently, and when the second included angle is larger than the ith first included angle, under the action of the suction force of the first electromagnet 25, the anemometer plate 24 moves leftwards to be in butt joint with the (i + 1) th first connecting rod 32 through the ith first cross rod 31, and because the right side surface of each first connecting rod 32 is a smooth surface, the friction between the first connecting rod 32 and the anemometer plate 24 can be ignored, and the anemometer plate 24 can still detect the change of the wind power. After the wind vane 24 moves to abut against the (i + 1) th first link 32, the wind force may be increased or decreased. When wind power increases, if wind power impels the second contained angle that anemometer plate 24 corresponds to be greater than the first contained angle of ith, be less than the first contained angle of i +1, then anemometer plate 24 can not move left under the blockking of the first connecting rod 32 of i +1, if wind power impels anemometer plate 24 corresponding second contained angle to be greater than or equal to the first contained angle of i +1, then under the suction effect of first electro-magnet 25, anemometer plate 24 passes through first horizontal pole 31 of i +1, move left to with the butt of first connecting rod 32 of i + 2. When the wind power is reduced, the wind measuring plate 24 applies pressure to the ith first cross rod 31, at this time, the pressure sensor on the ith first cross rod 31 detects the pressure and transmits a pressure signal to the controller, the controller counts the time length of the pressure signal detected by the ith pressure sensor after receiving the pressure signal detected by the ith pressure sensor, when the counted time length is longer than the preset time length, the first electromagnet 25 is controlled to be powered off, the second electromagnet 26 is controlled to be powered on for a corresponding time length, so that the sliding shaft 23 drives the wind measuring plate 24 to move rightwards to the right side of the ith first connecting rod 32, after the second electromagnet 26 is controlled to be powered on for a corresponding time length, the first electromagnet 25 is controlled to be powered off, the second electromagnet 26 is powered off, under the suction effect of the first electromagnet 25, the sliding shaft 23 drives the wind measuring plate 24 to move leftwards, if the corresponding second included angle of the wind measuring plate 24 is smaller than the ith first included angle, the wind measuring plate 24 is blocked by the ith first connecting rod 32, and if the second included angle corresponding to the wind measuring plate 24 is larger than the ith first included angle, the wind measuring plate 24 moves leftwards to abut against the (i + 1) th first connecting rod.
