1) dragging the tire, wherein when the tire enters a chasing detection area, a first position induction sensor sends a signal, conveying rollers of the left half roller area and the right half roller area rotate at a constant speed in the same direction, and the tire is conveyed to a centering station;
2) When the tire enters a centering station, a second position induction sensor sends a signal, a left arm holding group and a right arm holding group act, two arm holding groups in each arm holding group are turned to a holding state from an open state, and the tire is pushed to the transverse central position of a conveying roller;

4) Rotating and tracing, wherein the identification device scans the diameter area where the tire identity information carrier is located in the tire rotating process until the tire identity information carrier is identified and stored in the memory;
5) After the identification and positioning, after the identification of the tire identity information, the tire continues to rotate for a set time of 0.5 ~ 5 seconds, and then the rotation is stopped, so that the orientation of the tire identity information carriers on the tire is consistent;
6) Releasing the opening arm, and enabling the left arm-embracing group and the right arm-embracing group to act again, wherein two arm-embracing arms in each arm-embracing group are turned to an opening state from an embracing state, and the tire is left at the transverse central position of the roller conveying roller;
7) Lifting and weighing, namely lifting the tire upwards under the action of a lifting driver below the tire positioning frame until the tire leaves the surface of the conveying roller, and measuring the weight of the tire by a weighing sensor;
8) Integrating data, wherein the tire weight signal is integrated with the tire identity information in the memory and then stored, and the information is shared through a network for statistics and analysis;
9) the tire falls back, the tire positioning frame falls back downwards under the action of the lifting driver until the tire falls on the surface of the conveying roller, and the tire positioning frame continuously falls to an initial position;
10) And (4) sending out the tire, continuously rotating the conveying rollers in the left half roller area and the right half roller area at the same speed and the same direction to convey the tire backwards, and when the third position induction sensor sends a signal, leaving the tracking and sweeping detection area.
8. the method as claimed in claim 7, wherein the position sensor is one or two of a photoelectric switch and an ultrasonic proximity switch.
9. the integrated tire chase-down detection data collection method of claim 7, wherein the load cell is any one of a mechanical, resistance strain, or photoelectric load cell.
