摘　　要：针对玉米收获机械自动对行控制器在线更新用户程序的需求,基于统一诊断服务协议(Unified Diagnostic Service,UDS)设计了软件升级流程,并基于Python开发了对应的上位机软件。该上位机软件选用整机上已有的CAN总线作为通信网络,利用UDS协议规定的诊断服务实现了自动对行控制器的程序刷写。实际测试表明,该上位机软件能安全快速的在线更新自动对行控制器的用户程序。In response to the need for the corn harvester’s automatic alignment controller to update the user program online,a software upgrade process was designed based on the Unified Diagnostic Service(UDS),and the corresponding host computer software was developed based on Python.The host computer software selects the existing CAN bus on the corn harvester as the communication network,and uses the diagnostic service specified by the UDS protocol to realize the program flashing of the automatic alignment controller.The actual test shows that the host computer software can safely and quickly update the user program of the automatic alignment controller online.
