[0050] The front and back sides of the cover body 8-1 are both provided with a large U-shaped groove 811, and the groove opening of the large U-shaped groove 811 faces downward; the protective cover 8 can be ventilated.

[0051] A pair of rotating plates 8-2 and the connection of the cover body 8-1 are provided with small U-shaped grooves 821, the notches of the small U-shaped grooves 821 are upward, and the small U-shaped grooves 821 are communicated with the large U-shaped groove 811; when the weather is bad, the rainwater on the traffic air command unmanned aerial vehicle 1 and the rainwater in the waterproof cover 8 can flow out through the small U-shaped grooves 821.

[0053] The upper end surface of the connecting plate 421 is a plane. The protective cover 8 is made of transparent material, the internal width of the protective cover 8 is greater than the maximum width of the unmanned aerial vehicle, and the external width of the protective cover 8 is equal to the distance between the two U-shaped connecting strips 422; when the protective cover 8 covers the traffic air command unmanned aerial vehicle 1, the traffic light device 1-2 and the road monitoring device 1-3 can also be normally used through the organic glass, so that the protective cover 8 will not touch the traffic air command unmanned aerial vehicle 1 to cause damage.

[0054] Working principle:

[0055] As shown in Figure 1 When the traffic air command unmanned aerial vehicle 1 is insufficient (such as when the preset power is less than 5%, the traffic air command unmanned aerial vehicle 1 returns, and it should be noted that the preset power is sufficient to make the traffic air command unmanned aerial vehicle 1 return to the unmanned aerial vehicle charging platform 4 in the command range), the power reminding device transmits a signal to control the traffic air command unmanned aerial vehicle 1 to land on the unmanned aerial vehicle charging platform 4 through the control system, so that the landing gear 1-4 falls into the parking groove 414, and the traffic air command system can adopt the control system, which is the prior art, as shown in Figure 13 Two moving blocks 412 are controlled by the control system, and move to the center of the platform 410 until the two moving blocks 412 respectively touch the two stop blocks 411, so as to lock the traffic air command unmanned aerial vehicle 1, which can prevent the unmanned aerial vehicle from being blown off by the wind or being taken away by people, when the two landing gears 1-4 of the traffic air command unmanned aerial vehicle 1 are locked, the control system controls the telescopic rod 122 to extend downward, and the charging plug 121 is inserted into the charging jack 413 at the upper end of the platform 410 under the telescopic rod 122, so as to realize that the traffic air command unmanned aerial vehicle 1 is charged, the traffic light device 1-2 can command traffic, and the road monitoring device 1-3 can monitor and shoot.

[0056] When the external environment sensing device determines that it is currently a severe weather condition according to the monitored data (how to determine the weather according to the monitoring data and the internal preset data refers to the prior art), the control system causes the motor 9 to start rotating, which drives the lead screw 6 through the coupling 11, causing the lead screw 6 to rotate, and the lead screw nut 7 will descend because one of the lifting blocks 8-3 of the protective cover 8 is fixedly connected to the upper end of the lead screw nut 7, and the other lifting block 8-3 is slidingly connected to the light rod 10, so the protective cover 8 will stably descend, as shown in Figure 7 , to the state shown in Figure 8 , because the abutting block 8-4 between the rotating plate 8-2 and the lower end of the cover main body 8-1 abuts against the rotating plate 8-2, so the outer end surface of the rotating plate 8-2 is in contact with the control block 423, and because the protective cover 8 is still descending, as shown in Figure 10 , when the control block 423 is about to enter the small U-shaped groove 821 but has not yet entered, the critical state, because the widths of the large U-shaped groove 811 and the small U-shaped groove 821 are not less than the width of the control block 423, and then the control block 423 can enter the small U-shaped groove 821, as shown in Figure 11 , the rotating plate 8-2 is in contact with the upper end surface of the connecting plate 421, and because the protective cover 8 is still descending, the connecting portion of the rotating plate 8-2 and the cover main body 8-1 will move downward, and the control block 423 will pass through the small U-shaped groove 821 and the large U-shaped groove 811 in turn, until Figure 12 , the rotating plate 8-2 is completely coincident with the upper end surface of the connecting plate 421, and the control system controls the motor to stop rotating, at which time the protective cover 8 has completely covered the traffic air command unmanned aerial vehicle 1, which can protect the unmanned aerial vehicle from being eroded by heavy rain and damaged by hail in severe weather, and the upper end surface of the connecting plate 421 can form an angle with the horizontal plane, so that the rain brought in by the unmanned aerial vehicle can flow down along the rotating plate 8-2 to the small U-shaped groove 821, and then flow out of the traffic air command system, and because of the existence of the large U-shaped groove 811, wind can flow into the traffic air command system to achieve the effect of ventilation, keeping the inside of the protective cover 8 dry, and because the protective cover 8 is made of transparent material, the red and green light device 1-2 and the road monitoring device 1-3 can be used normally through the transparent material.

[0057] When the road monitoring device 1-3 monitors that the road traffic is high (the density of traffic flow can be determined by the prior art), and the traffic air command unmanned aerial vehicle 1 needs to perform air command operation, the traffic air command unmanned aerial vehicle 1 will send a signal to the control system, and the control system controls the motor 9 to rotate, which drives the lead screw 6 to rotate through the coupling 11, and the lead screw nut 7 will move upward, and because of the gravity of the rotating plate 8-2 itself, as shown in Figure 12 , the state will first change to Figure 11 , and then change to Figure 10The state then becomes like Figure 8 The state eventually became like Figure 7 In this state, the drone is fully charged. The control system will control the telescopic rod 122 to retract upwards, the charging plug 121 will move away from the charging socket 413, and the two moving blocks 412 will move away from the center of the tablet 410, at which point it becomes as follows: Figure 1 In this state, the traffic air command drone 1 will rotate its fan blades to take off, leave the traffic air command system, and head to conduct air command operations.

[0058] Because of the presence of the vertical telescopic rod 5, the protective cover 8 and the drone charging tablet 4 can move downwards under the control of the control system. Staff can regularly clean and maintain the system. After cleaning and maintenance, the protective cover 8 and the drone charging tablet 4 can move upwards under the control of the control system and rise to a high place. This can prevent theft and also make the traffic lights visible to vehicles behind, without creating blind spots due to obstruction by vehicles in front.

[0059] Example 2:

[0060] Unlike Embodiment 1, the upper surface of the connecting plate 421 is inclined downwards, and the end of the connecting plate 421 away from the plate body 4-1 is lower than the end of the connecting plate 421 near the plate body 4-1. The connecting plate 421 and the horizontal plane of the plate body 4-1 form a 20-degree angle. This allows rainwater inside the protective cover 8 to flow through the inclined surface of the connecting plate 421 to the small U-shaped groove 821, thereby preventing water accumulation inside the protective cover 8.

[0061] Example 3:

[0062] Unlike Embodiment 1, the traffic light device 1-2 is equipped with speakers 123 at both ends; this allows the traffic aerial command drone 1 to conduct traffic command while charging, and also allows voice command of traffic through the speakers 123. The voice command of traffic issued by the speakers 123 can also be transmitted to the outside through the large U-shaped groove 811, so as not to affect the purpose of traffic command.
