嵌入式以太网数据采集与控制系统设计

Embedded Ethernet Data Acquisition and Control System Design

摘要:

为了提高嵌入式以太网数据的操作精度,减少数据运行时间,增加数据运行灵活性以及稳定性,方便对嵌入式以太网数据进行的有效管理,需要对嵌入式以太网数据采集与控制系统进行设计;当前的嵌入式以太网数据采集与控制系统设计方法对以太网数据进行采集与控制系统设计时,因为无法对其进行灵活、高效、全面地采集和控制,存在数据运行盲区较多,成本较大的问题,所以提出一种基于LonWorks的嵌入式以太网采集和控制系统设计方法,即采用局部网格方式进行数据采集,使嵌入式以太网进行自维护、自组织、自控制的操作;该方法先利用μC/OSⅡ平台完成对嵌入式以太网数据采集与控制系统的硬件设计,然后依据互式数据迁移技术对嵌入式以太网进行数据采集,以采集的数据为基础,采用模糊关联空间理论对采集得到的以太网数据进行过滤,最后以上述过程为依据,利用OPC服务器程序对过滤后的嵌入式以太网数据进行控制,由此完成了嵌入式以太网数据采集与控制系统设计;实验结果证明,所提方法可以全面精确地对嵌入式以太网数据进行采集和控制,提高以太网运行速度,增强网络使用寿命,为该领域研究发展提供了强有力的依据。

Abstract:

In order to improve the operation of the embedded Ethernet data accuracy, reduces the running time data, increasing data operation flexibility and stability, convenient and effective management of embedded Ethernet data, put forward a design method of Embedded Ethernet data acquisition and control system based on LonWorks, which uses local mesh to carry on the data acquisition, the embedded Ethernet self maintenance, self organization and control operation. The method to use μC/OS Ⅱ platform of embedded Ethernet data acquisition and control system hardware design, and then on the basis of mutual on the embedded Ethernet technology for data migration data collection, based on the acquisition of data, using the theory of fuzzy correlation space of Ethernet data filtering, finally based on the above process, use of OPC server program to control the filtered embedded Ethernet data, thus completing the embedded Ethernet data acquisition and control system design. The experimental results show that the proposed method can comprehensively accurately complete the embedded Ethernet data acquisition and control, improve the speed of Ethernet, enhance the service life of the network, the research in the field development provides a strong basis.
