基于高速以太網(wǎng)現(xiàn)場總線（HSE）網(wǎng)絡(luò)冗余的研究

摘要首先介紹了當(dāng)前控制系統(tǒng)中網(wǎng)絡(luò)冗余的基本思想，然后分析了FF HSE 通信協(xié)議中網(wǎng)絡(luò)冗余系統(tǒng)的構(gòu)架，最后闡明了網(wǎng)絡(luò)冗余實體的實現(xiàn)過程。該實體能夠為上層應(yīng)用程序提供可操作的網(wǎng)絡(luò)接口，并且在網(wǎng)絡(luò)故障時實現(xiàn)透明切換，從而保證了HSE 網(wǎng)絡(luò)系
統(tǒng)的穩(wěn)定運行。

Abstract The basic concept of network redundancy in current control systems is introduced firstly. Then，the frame of network redundancy in FF HSE communication protocol is analyzed. The implementation procedure of network redundancy entity is described finally. The entity is able to provide operable network interface for application programs in higher，and implement transparent switchover while network fails，thus the stable operation of HSE metwork system is ensured.
