As shown in fig. 1, the section AB is a first section cleaning track, where a is a starting point of the first section cleaning track, B is an ending point of the first section cleaning track and is also a starting point of the second section cleaning track, and the section BC is a second section cleaning track, where B is a starting point of the second section cleaning track, and C is an ending point of the second section cleaning track. As shown in fig. 5, the slide rail is fixed on the bracket, and the brush is slidably connected to the slide rail through the slide block.

As shown in fig. 6, the method includes:

step S102: and when the brush is positioned in the first section of cleaning track, the controller controls the brush to rotate in the forward direction.

In one embodiment, the car washer further comprises: an encoder coupled to a motor for driving the conveyor, the encoder for outputting to the controller an encoded value indicative of coordinates of the nose of the vehicle 100 to be washed; the initial position of the brush is located at the starting point of the first section of track, and the starting point of the first section of track corresponds to a first coordinate;

when the brush utensil is located first section washing orbit, control brush utensil cisoid is rotated, specifically includes:

when the received code value is equal to a first preset code value, judging that the brush is positioned in a first section of cleaning track and controlling the brush to rotate in the forward direction; wherein, the first preset code value is used for indicating that the head of the vehicle 100 to be washed reaches the first coordinate.

The vehicle 100 to be washed is parked on the chain plate 200, the motor drives the chain plate 200, and the chain plate 200 drives the vehicle 100 to be washed to move forward. The car washing platform is used as a coordinate axis and is divided into a plurality of coordinates corresponding to different code values, and the controller can judge the rotating angle of the code disc according to the received code signals, so that the running length of the chain plate 200 is obtained, and the coordinates of the car are further judged. The first coordinate is the coordinate of the vehicle 100 to be washed when the vehicle 100 to be washed contacts the brush, and the first coordinate corresponds to the starting point of the first section of the washing track, namely, the point a. When the code value received by the controller is equal to the first preset code value, the brush is judged to be positioned in the first section of cleaning track and is controlled to rotate in the forward direction. The brush rotates in the same direction, and can prevent the license plate from being wound or overturned when the brush hair rotates rapidly.

Step S104: when the brush is located at the second section of cleaning track, the controller controls the brush to rotate reversely.

In one embodiment, the car washer further comprises: a first position sensor 230, the first position sensor 230 being adapted to detect that the brush reaches the start of the second segment of the cleaning track; the starting point of the second section of track corresponds to a second coordinate;
