Working principle:
As shown in fig. 1, when the electric quantity of the traffic air command unmanned aerial vehicle 1 is insufficient (for example, when the preset electric quantity is lower than 5%, the traffic air command unmanned aerial vehicle 1 returns, and it is required to be explained that the preset electric quantity is enough to enable the traffic air command unmanned aerial vehicle 1 to return to the unmanned aerial vehicle charging flat plate 4 in the command range), the electric quantity reminding device can control the traffic air command unmanned aerial vehicle 1 to drop onto the unmanned aerial vehicle charging flat plate 4 through a control system transmitting signal, so that the landing gear 1-4 just falls in the stop slot 414, the traffic air command system can adopt a control system, in the prior art, as shown in fig. 13, two moving blocks 412 are all controlled by the control system to move towards the center of the flat plate 410 until the two moving blocks 412 respectively touch against two stoppers 411, so as to achieve the purpose of locking the traffic air command unmanned aerial vehicle 1, the purpose of preventing the unmanned aerial vehicle from being blown down by a strong wind or being manually taken away, when the two landing gears 1-4 of the traffic air command unmanned aerial vehicle 1 are locked, the control system can control the telescopic link 122 to extend downwards, the charging plug 121 is inserted into the charging flat plate 413 at the lower end of the telescopic link 122, and the traffic air command unmanned aerial vehicle 1-3 can be monitored while the traffic air command device can be monitored, and the traffic air device can be monitored, and the traffic air device 1 can be monitored, and the traffic air device can be monitored.
When the external environment sensing device determines that the weather condition is bad according to the monitored data (particularly, how to perform weather determination according to the monitored data and the internal preset data referring to the prior art), the control system starts the motor 9 to rotate, the screw rod 6 is driven by the coupling 11, so that the screw rod 6 rotates, the screw rod nut 7 descends along with the descending, because one lifting block 8-3 of the protective cover 8 is fixedly connected to the upper end of the screw rod nut 7, the other lifting block 8-3 is slidingly connected to the polish rod 10, the protective cover 8 descends steadily, the state shown in fig. 7 changes into the state shown in fig. 8, because the supporting block 8-4 is arranged between the rotating plate 8-2 and the lower end of the cover main body 8-1, the supporting block 8-4 supports against the rotating plate 8-2, so that the outer end surface of the rotating plate 8-2 contacts the control block 423, since the shield 8 is still descending, as shown in fig. 10, in the critical state when the control block 423 is fast entering the small U-shaped groove 821 but not yet entering, since the widths of the large U-shaped groove 811 and the small U-shaped groove 821 are not smaller than the width of the control block 423, after which the control block 423 can enter the small U-shaped groove 821, as shown in fig. 11, the rotating plate 8-2 contacts with the upper end surface of the connecting plate 421, since the shield 8 is still descending, the connection of the rotating plate 8-2 and the shield body 8-1 moves downward, the control block 423 sequentially passes through the small U-shaped groove 821 and the large U-shaped groove 811 until the rotating plate 8-2 is completely overlapped with the upper end surface of the connecting plate 421 as shown in fig. 12, the control system controls the motor to stop rotating, at which time the shield 8 has completely covered the traffic air-guided unmanned aerial vehicle 1, can protect unmanned aerial vehicle not receive the damage by storm erosion, hail striking in bad weather, the up end of connecting plate 421 can personally submit an contained angle with the level, and the rainwater that unmanned aerial vehicle brought can flow down along rotating plate 8-2 until little U-shaped groove 821 department, and little U-shaped groove 821 department flows traffic air command system, because there is the existence of big U-shaped groove 811, wind can flow in traffic air command system, reaches the effect of ventilation, keeps the inside dry of protection casing 8 of system, and because protection casing 8 is transparent material, consequently can make traffic light device 1-2 and road monitoring device 1-3 see through transparent material normal use.
