    摘要:

    為了提高嵌入式以太網(wǎng)數據的操作精度,減少數據運行時(shí)間,增加數據運行靈活性以及穩定性,方便對嵌入式以太網(wǎng)數據進(jìn)行的有效管理,需要對嵌入式以太網(wǎng)數據采集與控制系統進(jìn)行設計;當前的嵌入式以太網(wǎng)數據采集與控制系統設計方法對以太網(wǎng)數據進(jìn)行采集與控制系統設計時(shí),因為無(wú)法對其進(jìn)行靈活、高效、全面地采集和控制,存在數據運行盲區較多,成本較大的問(wèn)題,所以提出一種基于LonWorks的嵌入式以太網(wǎng)采集和控制系統設計方法,即采用局部網(wǎng)格方式進(jìn)行數據采集,使嵌入式以太網(wǎng)進(jìn)行自維護、自組織、自控制的操作;該方法先利用μC/OSⅡ平臺完成對嵌入式以太網(wǎng)數據采集與控制系統的硬件設計,然后依據互式數據遷移技術(shù)對嵌入式以太網(wǎng)進(jìn)行數據采集,以采集的數據為基礎,采用模糊關(guān)聯(lián)空間理論對采集得到的以太網(wǎng)數據進(jìn)行過(guò)濾,最后以上述過(guò)程為依據,利用OPC服務(wù)器程序對過(guò)濾后的嵌入式以太網(wǎng)數據進(jìn)行控制,由此完成了嵌入式以太網(wǎng)數據采集與控制系統設計;實(shí)驗結果證明,所提方法可以全面精確地對嵌入式以太網(wǎng)數據進(jìn)行采集和控制,提高以太網(wǎng)運行速度,增強網(wǎng)絡(luò )使用壽命,為該領(lǐng)域研究發(fā)展提供了強有力的依據。

    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.
