Omni-directional mobile multi-load AGV control system and control method thereof

Abstract

The invention discloses an omni-directional mobile multi-load AGV control system and a control method thereof. The omni-directional mobile multi-load AGV control system comprises a main control modulefor power supply of a power supply module, a steering control module for controlling the AGV to accurately steer, a driving control module for controlling the AGV to advance or retreat at a certain speed, a multi-cargo transferring module for controlling the AGV to move to a to-be-taken cargo position to accurately take out the articles on the cargo rack, a man-machine interaction module for displaying AGV operation state information in real time, and a communication module for facilitates communication between the main control module and a mobile terminal. The steering control module, the drive control module, the multi-cargo transferring module, the man-machine interaction module and the communication module are all electrically connected with the main control unit. The control system can perform accurate motion control on the motion process of the omni-directional multi-load AGV proposed in the existing scheme, can switch motion modes according to different motion modes, and controls the AGV to complete an accurate goods storing and taking task after the AGV arrives at a 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
