The working principle of the highway law enforcement patrol aircraft:

Monitoring device and control unit: the background management system 35 and the mobile device 34 have a remote control effect on the patrol machine. According to the needs of the time, the background management system 35 can choose to connect with the mobile device 34 through the wifi wireless network, the Internet or the USB interface. Under the situation that is far away from background management system 35, mobile device 34 and background management system 35 can connect and communicate through wifi wireless network, mobile network, Internet, under the situation that mobile device 34 and background management system 35 are in connection, mobile The device 34 can use the USB interface to directly connect with the background management system 35 through a data line for data exchange. During use, when the patrol machine is powered on, the power management unit 29 in the control box starts to monitor the power supply of each unit in the patrol machine. Alarm and power-off protection, in addition, the power management unit 29 also has an over-power protection function, which can effectively ensure the power supply and power safety of the patrol machine during work, prevent the patrol machine from being damaged due to power supply problems, and reduce the risk of patrolling. The cost of using the machine. When the patrol machine is walking, if there is a power supply failure in a certain unit, the power management unit 29 will transmit the corresponding failure signal to the central controller 27, and the central controller 27 will transmit the failure information to the mobile device 34 and the background management System 35, according to the location information displayed by the internal GPS locator 33 of the patrol aircraft, the traffic police can directly go to the position displayed by the GPS locator 33 to reclaim the patrol aircraft or the backstage management system 35 notifies relevant personnel to reclaim the patrol aircraft. When it is necessary for the patrol machine to work at a designated location or to return to the starting place, the background management system 35 and the mobile device 34 can send a control command to the central controller 27, and the central controller 27 transmits the order to the walking control unit 28, and the patrol machine Under the control of the walking control unit 28, walk to the designated location to perform corresponding work or return to the starting place. When the power management unit detects that the power of the patrol machine is insufficient, the background management system 35 and the mobile device 34 can send a recall control command to the central controller 27, start the fast return mode, and walk to the recall position quickly. When the background management system 35 finds that the power of the patrol machine is exhausted, the background management system 35 can send a control command to the mobile device 34, requiring the traffic police to bring back the patrol machine to the position where the patrol machine stops. When the power supply is normal, the patrol machine is initialized, and the camera 1 receives the control signal sent by the central controller 27, and according to the set shooting resolution, the number of shooting frames per second and the number of photos, the road hard shoulder line or illegal parking When shooting within the parking space line, when encountering special placement of vehicles, special road conditions, or locations that cannot be reached by patrol aircraft, the top and bottom of the electric pan/tilt have two degrees of freedom of rotation, which can achieve circumferential rotation of 0-360° in the horizontal plane and 90° elevation angle or depression angle, the electric pan/tilt receives the control signal sent by the central controller 27 to make adjustments, and the camera 1 simultaneously performs long-distance photography of the vehicle and close-distance photography of the license plate during the shooting process, and transmits the photographs taken to the image processing unit 31. The image processing unit 31 uses a conventional image recognition method to perform image recognition processing. At the same time, the image processing unit 31 receives the location information of the photos sent by the GPS locator 33, marks the location information of the processed pictures and stores them in the storage unit 32. Whether the infrared detector detects whether there is a person approaching and whether there is an obstacle in the forward direction, when the infrared detector detects that there is a person approaching, the signal is transmitted to the central controller 27, and the central controller 27 is processed and then sent to the alarm. Receive an order to give an alarm, prompting that the patrol plane is a mobile traffic police, pay attention to avoiding, when the infrared detector detects that there is an obstacle in the forward direction, the signal is transmitted to the central controller 27, and the central controller 27 sends a command to the walking control after processing Unit 28, the travel control unit 28 issues commands to control the travel device. When the patrolling machine is within the walking range of the entire isolation guardrail, for photographing the situation of illegally parked vehicles, the central controller 27 sends a stop control signal to the walking control unit 28, and the walking control unit 28 controls the patrolling machine to stay and wait until there is an illegally parked vehicle. , the central controller 27 sends a start control signal to the walking control unit 28, and the walking control unit 28 controls the patrol machine to continue walking. The patrol aircraft relies on the camera 1 to judge whether it is a violation scene, relies on infrared detectors to judge whether there are others approaching or encounters obstacles and whether it reaches the end point, and relies on GPS positioning to judge whether it is in a designated position.

Power device, driving device and auxiliary fixing device: the DC motor receives the command of the walking control unit 28, and the driving device receives the power from the DC motor through the power device, and realizes actions such as forward, backward, obstacle surmounting and stop during road patrolling. , if the patrol aircraft encounters an obstacle that cannot be crossed or walks at the end of the isolation fence, it can stop or return. The battery 26 supplies power to the DC motor 24, and the remote signal is sent to control the forward and reverse rotation and output torque of the DC motor 24 through the central controller 27; the DC motor 24 transmits the torque to the driving gear shaft 5 through the coupling, and the driving gear shaft passes the The connection transmits the torque to the driving gear 4, the driving gear 4 transmits the torque to the driven gear 7 through meshing, the driven gear 7 transmits the torque to the driven gear shaft 6 through the key, and the driven gear shaft 6 transmits the torque to the power The unilateral wheel 21, the power unilateral wheel 21 bears the gravity of the frame 3 and its own gravity and is pressed on the top of the guardrail, and rolls back and forth through the friction with the guardrail; the upper transmission unilateral wheel 20 and the lower transmission unilateral wheel 13 are equally pressed Close on the guardrail, and roll on the guardrail due to friction; the flange of the power unilateral wheel 21 is attached to the top side of the guardrail, and the flanges of the upper transmission unilateral wheel 20 and the lower transmission unilateral wheel 13 are all attached to the guardrail.
