Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0020] Such as figure 1 , figure 2 As shown, the present invention proposes a method for reversing an AGV. Its structure includes a magnetic induction coil located at the front of the AGV drive wheel and a magnetic induction line located on the ground. The control method includes the following processes:

[0021] Determine two points A and B on both sides of the first magnetic induction coil;

[0022] Determine the voltage between two points A and B;

[0023] Power on the steering motor, and make sure that the motor turns to the "0" point as the initial position;

[0024] Determine the steering: compare the voltage difference between A and B, if the voltage difference is greater than 0, the motor will rotate forward, if the voltage difference is less than 0, the motor will...

Abstract

The invention provides an AGV backing-up method. The front part of an AGV driving wheel is provided with a magnetic induction coil and a magnetic induction line is located on the ground. A control method includes the following steps that the two sides of the first magnetic induction coil are determined as a point A and a point B; the voltage between the point A and the point B is determined; and asteering motor is powered on, the motor rotates to a 0-point position which is determined as the initial position, when the steering motor is powered on, the motor rotates to the 0-point position, position information of the steering motor can be identified, at the time, the voltage on the magnetic induction coil is collected, calculation is conducted, then the angle of the steering motor is controlled, and the precise backing-up function is achieved.

Description

technical field [0001] The invention relates to the field of AGVs, in particular to an AGV reversing method. Background technique [0002] Modern logistics is produced and developed along with the process of socialized large-scale production. With the advancement of science and technology and the expansion of trade scope, its functions are constantly expanding, and its service areas are constantly expanding. Therefore, the development of modern logistics presents an integrated and networked , intelligence, specialization, socialization, internationalization and other trends, and most of these trends are also presented on the development track of many other industries. [0003] When the AGV forklift advances to the station, it needs to reverse the car to pick up the goods. If there is no good algorithm, the steering angle will be insufficient or excessive, resulting in inaccurate positions for fork-picking goods, and precise backing control cannot be realized.
