When the head of the vehicle moves to a fifth preset position, the front skirt brush mechanism 101 is driven to move to a first position and run, and when the tail of the vehicle moves to the first preset position, the front skirt brush mechanism 101 is driven to move to a second position and stop running, wherein the third preset position, the fourth preset position and the fifth preset position are located between the first preset position and the second preset position. The fifth preset position is a position corresponding to the front skirt brush mechanism 101, and when the head of the vehicle moves to a position corresponding to the front skirt brush mechanism 101, the front skirt brush moves to the first position and operates to clean the vehicle, so as to prevent the vehicle from colliding with the front skirt brush mechanism 101.
Referring to fig. 1 to fig. 5, specifically, when the car washing method in this embodiment is implemented by the automatic car washing system in the above embodiment, it is first monitored whether a car stops on a car washing space, that is, a position corresponding to a long chain plate in this embodiment, when the car head reaches a first photosensitive sensor 601, the car stops running, an infrared emission end of the first photosensitive sensor 601 cannot receive an infrared signal, the first photosensitive sensor 601 is triggered, a determination signal is sent to a local PLC 800, and at this time, the local PLC 800 determines whether the car stops on the long chain plate. When the local PLC 800 judges that the long chain plate vehicle washing space is not stopped, the long chain plate and the short chain plate are controlled to start to operate, the rear skirt brush mechanism 102 is driven to move to the first position and operate the rear skirt brush mechanism 102, when the rear skirt brush mechanism 102 is positioned at the first position, at least part of the rear skirt brush mechanism 102 is positioned on the moving path of the vehicle, at the moment, the distance between the signal generating end and the signal receiving end is larger than the maximum distance required by the induction signal, the local PLC 800 cannot receive the induction signal, and cannot send a feedback signal to the early warning assembly 400, the early warning assembly 400 is in a dormant state, and the display lamp is turned off.
After the rear skirt brush mechanism 102 is cleaned, the chain plate drives the vehicle to move from the vehicle washing, when the tail of the vehicle reaches the first photosensitive sensor 601, the infrared emission end of the first photosensitive sensor 601 receives the infrared signal again, the first photosensitive sensor 601 triggers stopping, a feedback signal is sent to the local PLC 800, the local PLC 800 sends a signal to drive the rear skirt brush mechanism 102 to move to a second position and stop running the rear skirt brush mechanism 102, and when the rear skirt brush mechanism 102 is in the second position, the rear skirt brush mechanism 102 is separated from the moving path of the vehicle, at the moment, the distance between the signal generation end and the signal receiving end is smaller than the maximum distance required by the induction signal, the local PLC 800 can receive the induction signal and send the feedback signal to the early warning assembly 400, the early warning assembly 400 is in an activated state, and the display lamp is lightened. If the local PLC 800 does not receive the induction signal at this time, the display lamp of the early warning assembly 400 is not always turned on, and the abnormal occurrence of the rear skirt brush at this time is proved.
The local PLC 800 stores a preset length value, and when the headstock reaches the second photosensor 602, the second photosensor 602 records the headstock origin coordinate, and at this time, the first photosensor 601 records the tailstock origin coordinate. When the distance between the real-time position coordinates of the vehicle head and the origin coordinates of the vehicle head reaches the preset length value stored in the local PLC 800, the local PLC 800 sends a signal to control the front skirt brush mechanism 101 to move to the first position and operate the front skirt brush mechanism 101, when the front skirt brush mechanism 101 is at least partially positioned on the moving path of the vehicle in the first position, at the moment, the distance between the signal generating end and the signal receiving end is larger than the maximum distance required by the induction signal, the local PLC 800 cannot receive the induction signal, does not send a feedback signal to the early warning assembly 400, the early warning assembly 400 is in a dormant state, and the display lamp is turned off. When the distance between the real-time position coordinates of the vehicle tail and the original point coordinates of the vehicle tail reaches the preset length value stored in the local PLC 800, the local PLC 800 sends a signal to control the front skirt brush mechanism 101 to move to the second position and stop running the front skirt brush mechanism 101. In the second position, the front skirt brush mechanism 101 is separated from the moving path of the vehicle, at this time, the distance between the signal generating end and the signal receiving end is smaller than the maximum distance required by the sensing signal, the local PLC 800 can receive the sensing signal and send a feedback signal to the early warning assembly 400, the early warning assembly 400 is in an activated state, and the display lamp is turned on. If the local PLC 800 does not receive the sensing signal at this time, the display lamp of the early warning assembly 400 is not turned on all the time, and it is proved that the front skirt brush mechanism 101 is abnormal at this time.
