| Abstract: | In this paper,a design method of combine harvester threshing performance parameters collector based on CAN bus is introduced.Each CAN intelligent control is built by LM3S8962.And taking advantages of CAN multi-master communication,each node sends the collected data to the PC.By PC processing and control,the threshing cylinder of combine harvester intelligent acquisition and control is realized.In addition,the monitoring software interface that based on Labwindows/CVI is designed to provide the operator a friendly user interface and operating platform,which achieves real-time data display and storage.This system is flexible,reliable,anti-jamming and the communication speed is high,which is a good solution to combine harvester data acquisitionand control system. |
