Abstract:
Disclosed is a conveying and positioning system and method, which is applied in the technical field of conveyance in the automotive industry and comprises a roller machine, a conveying trolley and an intelligent variable-frequency controller, wherein the conveying trolley is provided with a reflector; the roller machine is provided with a driving mechanism and a distance sensor; and, the driving mechanism comprises a driving motor controlled by the intelligent variable-frequency controller and a rotary encoder capable of feeding back rotation speed information of the driving motor to the intelligent variable-frequency controller. In the present invention, with the intelligent variable-frequency controller, by reading position information fed back by the distance sensor and rotation speed information fed back by the rotary encoder, accurate voltage frequency control information is output by internal operation so as to control the rotation speed of the driving motor, so that a double closed loop control mode of the conveying and positioning system is realized. In the present invention, fast conveyance, accurate positioning and stable operation of the conveying trolley can be realized by the technical solutions in the double closed loop control mode, and the cost is low.

Claim (Index 10):
A conveying and positioning method, comprising:\n controlling, by an intelligent variable-frequency controller, a driving motor on a roller machine to drive a conveying trolley to move along the roller machine, such that, along with the conveying trolley, a reflector disposed on the conveying trolley entering a detection range of a distance sensor disposed on the roller machine; recognizing, by the distance sensor, position information of the conveying trolley in a conveying process by receiving a signal from the reflector, and feeding back the position information to the intelligent variable-frequency controller; feeding back, by a rotary encoder, rotation speed information of the driving motor to the intelligent variable-frequency controller; combining, by the intelligent variable-frequency controller, the position information of the conveying trolley fed back by the distance sensor and the rotation speed information of the driving motor fed back by the rotary encoder, and comparing the position information with a target position information of the conveying trolley preset in the intelligent variable-frequency controller; outputting an accurate voltage frequency controller information to control the rotation speed of the driving motor to slow down the conveying trolley; and, controlling, by the intelligent variable-frequency controller, the driving motor to stop rotating upon the conveying trolley reaching a preset position, so that realizing an accurate positioning for the conveying trolley.
