AGV key technologies and development trends

Replacing the traditional manual handling method with AGV carts can not only greatly improve working conditions and environment, increase the level of automated production, but also effectively liberate labor productivity, reduce the labor intensity of workers, reduce staffing, optimize production structure, save manpower, Material and financial resources. In the automated logistics system, compared with other equipment commonly used in material transportation, AGV has the advantages of no need to lay rails, support frames and other fixed devices, and is not limited by site, road and space. It can fully reflect its automation and Flexible to realize efficient, economical and flexible unmanned production.

AGV key technologies and development trends

Agv architecture

1. AGV Guidance technology

As a branch of wheeled mobile robots, AGV's main feature is automatic guidance. With the development of various technologies, AGV's guidance technology has also been continuously improved. At present, the commonly used guidance methods are: electromagnetic guidance, magnetic tape guidance, ribbon guidance, laser guidance, inertial guidance, visual guidance, GPS guidance, coordinate guidance, etc.

2.AGV Drive mode

At present, the common driving methods of AGV can be summarized into four types: single-wheel drive, differential drive, two-wheel drive, and all-round drive. According to the number of wheels, there are mainly three-wheel models and four-wheel models. When selecting the model, choose according to the actual road conditions and functional requirements of the work site.

3. AGV Power supply

The traditional AGV power supply generally uses batteries as energy storage carriers. Currently, the types of batteries that can be used by AGV are: lead-acid / pure lead, nickel-metal hydride, nickel-cadmium, and lithium-ion batteries. In recent years, with the maturity of battery technology, the application of super capacitors in AGV has gradually been promoted, and with the development of contactless energy transmission technology, related products have replaced the traditional power supply mode of AGV in some fields.

4. AGV System control

It is mainly divided into ground (upper) control system and vehicle-mounted (lower) control system. The higher-level control system effectively controls multiple AGVs, optimizes the ordering of tasks, dynamically plans the distribution of AGVs and driving paths, and realizes intelligent traffic management. After receiving the instructions from the higher-level system, the lower-level control system is responsible for functions such as navigation calculation, guidance implementation, vehicle walking, and loading and unloading operations.
