拖拉机多源作业载荷边缘解算专用FPGA平台设计
Design of A Dedicated FPGA Platform for Edge Computing of Multi-source Operational Loads in Tractor
摘要
Abstract
To acquire load data under high-load operations such as subsoiling,a multi-source load testing and edge-solving system based on a system on chip(SoC)field-programmable gate array(FPGA)was proposed.The system integrated chassis strain,three-point hitch draft force,driveline torque,vibration acceleration,controller area network(CAN)bus signals,and real-time kinematic global navigation satellite system(RTK-GNSS)position information into a unified platform.To balance accuracy and resource efficiency,online preprocessing such as multi-channel synchronous analog-to-digital converter(ADC)sampling,timestamp insertion,and digital filtering were implemented on the programmable logic(PL)side,while protocol parsing,data management,and tire vertical load inversion were executed on the processing system(PS)side as edge-computing tasks.Field subsoiling tests with a 200-hp wheeled tractor showed that the system operated stably and continuously;FPGA-side preprocessing achieved significantly higher time-efficiency than the onboard central processing unit(CPU),and good synchronization across multi-source data was maintained.The tire vertical loads estimated by the inversion model agreed well with the actual operating conditions.The proposed system provided an integrated test platform to support tractor load spectrum development and durability research on key components.关键词
