Positioning control method and device for RGV system, storage medium and equipment

Abstract

The invention provides a positioning control method and device for an RGV system, a storage medium and equipment, and the method comprises the steps: obtaining the initial position of an RGV on a guide rail, obtaining the target position of the RGV according to the positioning condition of the RGV, setting the driving parameters of the RGV according to the initial position and the target position, and controlling the RGV to run to a target position according to the driving parameters. The position information of the RGV is monitored in real time through the laser range finder, and the frequency converter is controlled to drive the motor to execute corresponding positioning according to the position information. And the operation process is simple, the cost is saved, the fault rate is low, compared with a traditional positioning mode, the device is safer, and the stability and practicability of the equipment are improved.

Description

technical field [0001] The invention relates to the field of intelligent logistics storage, in particular to a positioning control method, device, storage medium and equipment of an RGV trolley system. Background technique [0002] RGV trolley, also called rail shuttle trolley, refers to the rail guided vehicle (Rail Guided Vehicle, RGV for short) used in various high-density storage warehouses. At present, the coordination between the RGV trolley and the assembly line body is becoming more and more frequent. The RGV trolley and the assembly line body are docked for loading and unloading operations. This requires frequent control of the RGV trolley to quickly, accurately and stably locate the position where it is docked with the line body to complete loading and unloading, and then Higher requirements are put forward for the positioning control method of the RGV trolley. [0003] The positioning control of the traditional RGV trolley includes servo drive or encoder combined...

AI Technical Summary

Problems solved by technology

Among them, the cost of servo drive is high when it is used to control high-power motors. The encoder combined with the inverter positioning method needs to return to the zero point after the system is powered off. The operation is complicated, and the above two positioning methods also have limited transmission distance, complicated operation, and difficult maintenance. , high equipment failure rate and other shortcomings, which is not conducive to improving production efficiency
