The control unit 27 is disposed inside the UAV 21 and is electrically connected to the UAV 21, the communication element 22, the display unit 23, the vehicle identification module 25, and the warning devices 26.

Referring to the fourth and fifth figures, the traffic command system executes a traffic command method. The traffic command method includes a request step S01, a receiving step S02, a starting step S03, a photograph recognition step S04, and an operation step S05. A control step S06, and a recovery step S07.

With reference to the first figure, in the request step S01, the vehicle body 1 will send a request command signal when passing through the intersection, the request command signal includes a positioning information of the vehicle body 1, the request command signal is the wireless signal.

In the receiving step S02, the communication element 22 receives the request command signal and transmits the request command signal to the control unit 27.

With reference to the second figure, in the starting step S03, the control unit 27 locates the position of the vehicle body 1 according to the request command signal, and accordingly controls the unmanned aerial vehicle 21 to fly to a preset position. In this example, The preset position is, for example, a position at the center of the intersection and a height of five meters from the ground, so that all vehicles passing the intersection can notice the traffic command device 2.

In the photography recognition step S04, the photography unit 24 shoots a continuous image, the vehicle recognition module 25 receives the continuous image, and identifies a plurality of moving objects with color difference from the road surface from the continuous image and determines the Such objects are multiple car body information.

In the calculation step S05, the control unit 27 generates judgment information based on the vehicle body information and the request command signal, the judgment information relating to whether the vehicle body 1 has a smooth travel path while driving.

In the control step S06, if the control unit 27 determines that the vehicle body 1 has a clear travel path while driving, the control unit 27 controls the display screen corresponding to the direction of travel of the vehicle body 1 The screen 231 displays the emergency indicator light, and the other display screens 231 corresponding to different directions of travel of the vehicle body 1 display the stop traffic lights, and at the same time, the control unit 27 controls the warning devices 26 to generate the Warning action to attract the attention of the vehicle at the intersection, other vehicles in a different direction of travel than the body 1 notice that the stop traffic lights displayed on the display screen 231 will stop to polite the body 1, and the vehicle Other vehicles traveling in the direction of the body 1 seeing the emergency indicator displayed on the display screen 231 will notice the moving line of the vehicle body 1 to make a polite action. If the control unit 27 determines that the vehicle body 1 has no unobstructed path of travel, the control unit 27 controls the display screens 231 corresponding to the direction of travel of the vehicle body 1 to display the forward traffic lights respectively, and controls The other display screens 231 corresponding to the direction of travel of the vehicle body 1 are not parallel to the stop traffic lights to quickly clear the congested vehicles in front of the vehicle body 1. Similarly, the control unit 27 controls the warning devices 26 respectively Such warning actions are generated to attract the attention of vehicles at the intersection.

In the recovery step S07, when the vehicle body 1 passes through the intersection, and the control unit 27 does not receive the request command signal from the communication element 22, the control unit 27 controls the display unit 23 and the warnings The aircraft 26 stops operating, and controls the UAV 21 to fly back to the standby position.

It should be added that the traffic command device 2 does not need to determine whether the vehicle body 1 has a clear travel path, and can directly jump from the start step S03 to the control step S06, and the control unit 27 directly controls the instruction The display screen 231 corresponding to the traveling direction of the vehicle body 1 displays the emergency indicator light, and the control indications correspond to the different traveling direction of the vehicle body 1. The other display screens 231 display the stop traffic lights, or, the control unit 27 The control screens 231 corresponding to the direction of travel of the vehicle body 1 display the forward traffic lights respectively, and the control screens 231 corresponding to the direction of travel of the vehicle body 1 display the stop traffic lights.

Referring to the sixth and seventh figures, a second embodiment of the traffic command system of the present invention is similar to the first embodiment, except that the traffic command system includes a control device 3, and the traffic command device 2 receives The request command signal sent by the control device 3, and the display unit 23 of the traffic command device 2 include a plurality of traffic signal lights 232, the traffic signal lights 232 are connected to the UAV 21, and surround the UAV 21.

With reference to the fifth figure, in the request step S01, the control device 3 may be operated by a traffic police, for example, the control device 3 sends out the request command signal, the request command signal includes a control time. The receiving step S02, the starting step S03, and the photography recognition step S04 are similar to the first embodiment, except that in the starting step S03, the control unit 27 controls the preset position to which the UAV 21 flies to, for example, the At the center of the intersection and at a height of three meters from the ground, vehicles passing by the intersection can notice the traffic command device 2. In the calculation step S05, the control unit 27 generates flow information based on the vehicle body information, and the flow information is related to a vehicle flow in the shooting area of the photographing unit 24. In the control step S06, the control unit 27 controls the display unit 23 to display based on the flow information. For example, when the control unit 27 determines that the traffic flow in one of the traveling directions is relatively large, the control unit 27 controls the travel parallel to the traveling The traffic signal lights 232 corresponding to the direction display the green light for a longer time to clear the congested traffic as soon as possible. Similar to the first embodiment, the control unit 27 also controls the warning devices 26 to generate the warning actions respectively To attract the attention of vehicles at the intersection. In the recovery step S07, after the traffic command device 2 executes the photograph recognition step S04, the calculation step S05 and the control step S06 to the control time, the control unit 27 controls the display unit 23 and the warning devices 26 Stop action, and control the UAV 21 to fly back to the standby position.

In summary, the communication unit 22 of the traffic command device 2 receives the request command signal, the control unit 27 controls the display unit 23 to display the traffic instructions, then the traffic command The device 2 can immediately replace the vehicles on the road commanded by the traffic police to give way to the official car, shorten the traffic time of the official car, and can also help command to clear the congested traffic, which can reduce the manpower burden of the traffic police to stay at the intersection at any time, and can To avoid the danger of traffic police in directing traffic, the control unit 27 generates the judgment information and the vehicle body information generated by the camera unit 24 and the vehicle identification module 25 of the traffic command device 2 With the flow information, the control unit 27 can control the display unit 23 to display the traffic instructions more accurately.

Based on the description of the above embodiments, the operation, use and effects of the present invention can be fully understood. However, the above-mentioned embodiments are only preferred embodiments of the present invention, and cannot be used to limit the implementation of the present invention.
