摘　　要：粮库监控系统的监控分机是实现CAN控制网络与系统主机通信的关键。监控分机是采用ARM处理器的控制系统,其软件采用Qt/E的多线程机制实现数据采集的快速性和实时性。本文提出粮库监控系统分层体系模型,介绍了利用Qt/Embedded编程工具设计的监控分机软件系统的GUI程序,并利用多线程技术解决现场CAN控制网络的多机通讯问题,最后将程序移植到ARM9系统中进行调试,结果表明程序运行稳定,数据采集的效率高。Monitoring Extension based on ARM controller is the core of Granary Monitoring System.It is the key of communication between CAN control network and host computer.This paper presents a kind of hierachical system model of the Granary Monitoring System.The Monitoring Extension GUI program which was designed by Qt/Embedded is introduced.Multithreading method is used to solve the problem of CAN bus multi-machine communication.Lastly the program is transplanted to ARM9 system and debugged.The result show that it can run steadily with efficient data collecting.
