What is AGV (Automated Guided Vehicle) ?

AGV (Automated Guided Vehicle) can generally control its route and behavior through a computer. It has strong self-adjustment, high degree of automation, accuracy and convenience, can effectively avoid human errors and save human resources. In the automated logistics system, rechargeable batteries are used as the power source to achieve flexibility, efficient, economical and flexible unmanned work and management.

 

Types of AGV Vehicle Controllers

The vehicle controller is the core of the control system and even the entire AGV. The vehicle controllers used by AGV are basically divided into the following three types:

 

  • PLC:PLC has the advantages of high reliability, easy programming, and flexible expansion, and is suitable for most AGV application scenarios. However, PLC also has disadvantages such as high cost and large size.
  • ARM Industrial Computer:ARM Embedded Computer is actually a computer with powerful computing power and flexible expansion capabilities. It has strong anti-interference capabilities and can be used in harsh industrial environments such as vibration and electromagnetic radiation. ARM Embedded Computer has a compact structure and small size, and can run general operating systems such as Linux.
  • Microcontroller:The advantages of microcomputers include low cost, low power consumption, and small size, making them suitable for small and medium-sized, cost-sensitive AGV applications. However, the shortcomings of microcomputers, such as limited computing power and limited storage space, also limit their scope of application.

 

The Composition of AGV

Traditional AGV system

Traditional AGV systems mainly rely on PLC, IO modules, switches, 4G routers and other devices to work together.

  • PLC as control center: responsible for receiving data from sensors and controlling the actions of AGV according to preset logic.
  • IO module: used to connect various sensors and actuators to realize signal conversion and transmission.
  • Switch: ensure smooth communication between various components.
  • 4G router: provides connection with external systems to realize remote monitoring and data exchange.

Although traditional systems can meet basic automation needs, they have some obvious limitations:

 

  • High hardware cost: multiple independent devices need to cooperate with each other to achieve complete functions.
  • Complex maintenance: The complexity of the system leads to high maintenance costs and high requirements for the expertise of technicians.
  • Difficult expansion: adding new functions or changing existing settings is cumbersome, which limits the flexibility of the system.
