摘　　要：针对传统PLC工业控制器效率比较低,可靠性比较差的缺点,利用ARM9嵌入式开发平台,结合嵌入式Linux的优势,研究并设计用于工业生产环境的智能监测与控制系统。完成了工业控制器的硬件电路设计,并开发出基于嵌入式Linux的控制软件。实际运行结果表明,该工业控制系统的整体性能良好,触摸屏为用户提供友善的人机交互界面,提高操作平台的易用性,网络摄像头对工业环境进行集中监控。本系统软件具有兼容性强,高可扩展性和开发周期短的特点,极大的减小了控制系统的维护成本和难度,能够满足当今社会对工业自动化越来越高的要求。Aiming at the relatively low efficiency and poor reliability of the traditional PLC industrial controllers, intelligent monitoring and control system for industrial environments is studied and designed in this paper. It is based on ARM9 embedded development platform, and takes the advantages of embedded Linux. The hardware design of industrial controllers and Linux-based embedded control software is described. Actual operating results showed a good overall performance of the industrial control system. The touch screen can provide users with a friendly interactive interface, improving the user experience.The webcam can provide centralized monitoring of industrial environment. The system software has advantages of compatibility,high scalability and features short development cycle, greatly reducing the cost and difficulty of maintaining control systems,being able to meet today＇s increasing demands of industrial automation.
