Heavy-Duty AGV: Technical Specifications, System Design & Applications in Construction Machinery

I.Heavy-Duty AGV Design Plan​

​​(1) Chassis Design​

• ​Core Positioning:​​ The main load-bearing structure of the heavy-duty AGV, directly impacting load capacity and structural stability.
• ​Structure and Materials:​​ Constructed from welded steel beams using high-strength steel with excellent weldability. The integrated unitary structure increases load capacity and reduces deformation.
• ​Component Configuration:​​ The chassis base is equipped with 4 drive wheels and 2 steering wheels. It integrates key components internally, including control elements, navigation elements, lithium batteries, etc.

​​(2) Control System​

• ​Core Function:​​ Manages motion control, positioning, and navigation for individual AGVs. Communicates with the AGV management and monitoring computer via wireless WLAN to receive dispatch commands and feedback vehicle status.
• ​Components:​​ Includes the onboard controller, drive units, QR code navigation sensors, power supply system, laser obstacle avoidance sensors, touchscreen, etc.

​III. AGV Management and Monitoring System​

​​(1) System Core Components​

Includes AGV system management and scheduling software, AGV monitoring module, AGV scheduling interface software, and the hardware device (AGV management and monitoring computer). It serves as the core of the AGV transportation system.

​​(2) Core Functions​

1. ​Basic Functions:​​ Path planning and design, dispatching AGVs to execute transport tasks, real-time system monitoring, controlling automatic charging, fault diagnosis, and external data exchange.
2. ​Management & Scheduling Functions:​​
• ​Cycle Time Management:​​ Set and manage the production cycle time of the assembly line handling system.
• ​Vehicle Management:​​ Control AGVs to sequentially complete assembly tasks at various stations based on their positions and status.
• ​Traffic Management:​​ Manage all AGVs in real-time to follow planned routes, implement mutual yielding, and ensure smooth operation.
• ​Communication Management:​​ Communicate with the raw material warehouse logistics management system via wired LAN, and command AGVs via wireless LAN.
3. ​Control & Management Functions:​​ Monitor AGV task execution, query AGV status/traffic information/data acquisition signals, resolve route conflicts, check communication status, and query intermediate stop/fault information.
4. ​Graphical Monitoring Functions:​​
• Dynamically display AGV working positions and operational status (Running, Charging, Manual, E-stop, Fault Stop, etc.), as well as station point and charging point occupancy information.
• Support user permission management, viewing/setting data acquisition system status, AGV tracking and blockage release, and abnormal event management (including event filtering).

​IV. Specific Applications of Heavy-Duty AGV in the Construction Machinery Industry​

​​(1) Assembly Line Handling Application​

• ​Operation Process:​​ The AGV travels along the assembly line, stopping at each station sequentially. Upon completion of a production step, triggered automatically by station-side sensors or AGV management software, or manually via a station-side call terminal, the AGV automatically proceeds to the next station.
• ​Application Value:​​ Connects various production processes, ensuring continuous material supply to the assembly line.

​​(2) Dynamic Management of Charging Function​

• ​Design Background:​​ The continuous nature of assembly tasks prevents AGVs from leaving for a centralized charging area mid-process.
• ​Implementation Plan:​​ Automatic charging functionality is installed at two stations on the main circuit. When an AGV docks to complete an assembly task, the management system assesses the battery level and controls automatic charging. Charging stops automatically at the end of the production cycle, and the AGV continues subsequent processes. Emergency charging plugs are also available at charging stations for manual charging.

​V. Summary of Application Results​

1. Solves the real-time material supply challenge for assembly lines in the construction machinery industry, serving as a successful application case within the industry.
2. Effectively improves assembly efficiency by combining global path planning with local path planning.
3. Ensures stable, efficient, and safe system operation through comprehensive collision avoidance design and monitoring management, effectively preventing collisions between AGVs, personnel, and objects.
