A multi-carrier AGV control system capable of omnidirectional movement and its control method

Abstract

The invention discloses an omnidirectional mobile multi-load AGV control system and a control method thereof, including a main control module and a power supply module for power supply; a steering control module for controlling the precise steering of the AGV; and a drive control module for controlling the AGV at a certain speed Forward and backward; the multi-cargo transfer module is used to control the AGV to move to the place where the goods are to be picked up to accurately take out the items on the shelf; the human-computer interaction module displays the AGV running status information in real time; the communication module is convenient for the main control module and the mobile terminal communication. The steering control module, drive control module, multi-cargo transfer module, human-computer interaction module, and communication module are all electrically connected to the main control unit. The control system can control the movement of the omnidirectional multi-load AGV proposed in the existing scheme The process performs precise motion control, and can switch the motion mode according to different motion modes, and control the AGV to complete the precise storage and retrieval tasks after reaching the designated position.

Description

technical field [0001] The invention relates to the field of AGV control, in particular to a multi-carrier AGV control system capable of omnidirectional movement and a control method thereof. Background technique [0002] As the key core equipment of intelligent logistics, AGV is an automation equipment integrating machinery, electronics, sensors, and control. It is widely used in machining, automobile, military industry, home appliance production, microelectronics manufacturing, tobacco, e-commerce warehousing, etc. multiple industries and fields. At present, the traveling process of AGV is mainly realized by differential drive, and for the AGV that can realize all-round movement, its steering displacement process is mainly realized by two kinds of mecanum wheels or omnidirectional wheels. It is not stable enough, and considering its cost, it is not widely used. At the same time, the current AGV handling trolley can generally only pick up and deliver one item at a time. I...

Problems solved by technology

At present, the traveling process of AGV is mainly realized by differential drive, and for the AGV that can realize all-round movement, its steering displacement process is mainly realized by two kinds of mecanum wheels or omnidirectional wheels. Not stable enough, and considering its cost, the adoption is not wide enough

At the same time, the current AGV handling trolley can generally only pick up and deliver one item at a time. In the case of a large order volume, the delivery task can only be completed by increasing the delivery frequency of the AGV. passed a certain test

[0003] For the occasion demand of AGV, different occasions require different movement modes. For example, industries such as medicine and fragile goods processing will put forward higher requirements for the stability of AGV movement process, but the transportation of goods in industries such as 3c and traditional machining , its stability requirements will be lower, but it requires AGV to have higher operating efficiency

In the prior art, there is a multi-load AGV that can move in all directions without being based on omnidirectional wheels. The AGV can keep the direction of the overall body unchanged during the steering process, and the stability of the transportation process is greatly improved. However, this technology Its control system has not been designed and described
