【摘要】：随着SCADA系统在国内工业企业的广泛应用与发展,RTU产品作为SCADA系统的重要组成部分,对其在实时性、稳定性、通信能力等功能的要求也越来越高。嵌入式终端由于很好的支持实时性,具有强大的通信能力,良好的人机界面,非常适合作为新一代RTU平台。本文基于ARM9硬件平台和嵌入式Linux系统,设计了一种用于分布式变电站SCADA系统的RTU设备,实现现场数据处理、与调度中心通信。本系统主要采用CAN总线与现场第三方检测设备连接,在嵌入式Qt/Embedded环境下进行软件设计,包括人机交互界面的建立、重要电力数据参数存储,完成标准电力系统暂态数据交换通用格式COMTRADE转换,最终实现通过以太网与调度中心联动,完成现场监控、数据存储、远程监控。
[Abstract]:With the wide application and development of SCADA system in domestic industrial enterprises, as an important part of SCADA system, it has been applied in real time and stability. The requirement of the function such as communication ability is more and more high. The embedded terminal has strong communication ability and good man-machine interface because of its good support for real-time, so it is very suitable for the new generation of RTU platform. Based on ARM9 hardware platform and embedded Linux system, a kind of RTU equipment for distributed substation SCADA system is designed in this paper, which realizes field data processing. Communication with dispatching center. This system mainly uses CAN bus to connect with field third party detection equipment, and designs software under embedded Qt/Embedded environment, including the establishment of man-machine interface, important power data parameter storage, etc. The standard power system transient data exchange universal format COMTRADE conversion is completed, and finally the linkage between Ethernet and dispatching center is realized, and field monitoring, data storage and remote monitoring are completed.
