【摘要】 在现代工业生产中,一些设备的正常运行对工厂的正常运行有着决定性的意义,所以有必要对这些设备进行实时监测,但传统的监测方法已不能满足功能复杂化、更新快速化、使用便捷化、操作自动化、信息共享化、分析智能化的要求,所以对新型监测系统的研究和开发显得尤为重要。本文通过对嵌入式网络的设备状态监测模式的研究,设计了以32位ARM9为核心的下位机控制器,通过网络连接与远程PC机共同构成设备状态监测系统。相比传统的8位或16位单片机构成的系统,此系统可以更好的满足现阶段复杂的工作要求。在系统中,硬件电路设计了S3C2410核心板电路和外围扩展电路,并对电路进行了调试;软件部分进行了Bootloader和Linux操作系统的移植以及驱动程序的开发和调试。利用虚拟仪器构建了远程客户端,对信号进行了分析研究。使用网络芯片和经过精简的TCP/IP协议栈实现的上下位机通信,达到了操作自动化、信息共享化的要求。该系统充分利用了S3C2410丰富的网络功能和Linux嵌入式操作系统的特点,实现了设备运行中的状态参数实时采集,并通过以太网实现数据传送和实时监测的功能。整个系统成本低廉,功能全面,具有较好的应用价值和推广价值。更多还原

【Abstract】 In modern industrial production, a number of the normal instruments and equipment decided the factory of normal operation in safety, so it is very necessary for these machines and equipment to monitor, but the traditional way of monitoring is high to staff requirements, while in some poor or dangerous working environment, the traditional instruments and meters have been unable to meet the function of the complex, fast update, easy to use, operation automation, information sharing and intelligence analysis of the requirements. Therefore, researching and developing a new type of monitoring system is especially important.In the paper, I researched on the embedded network equipment condition monitoring mode. On this basis, controller designed by 32-bit ARM9 core connected with a remote PC, constituted a condition monitoring equipment. Compared to the traditional 8-bit or 16-bit single-chip system, the system can better meet the present complexity of the job requirements. In the system, the S3C2410 core of the circuit board and the expansion of the external circuit were designed and debugged; Bootloader and Linux operating system were transplanted, as well as driver Procedure was developped and debugged. The virtual machines built remote client, analyzed the signals. Through the use of network chips and streamline the TCP/IP protocol stack to achieve the upper and lower machine communication, it meet the operation of automation and information sharing requirements.The system made full use of the rich network function of S3C2410 and the characters of embedded Linux, and realizes real-time acquisition parameters, data transmission and real time supervision by Ethernet. The module is low cost, full function, has better application and extension value.更多还原
