基金会现场总线预测功能块的设计与实现

提高工业以太网现场总线确定性的一个重要手段就是减少总线网络的通讯量。以基金会现场总线高速以太网 (HSE)为研究对象 ,提出一个全新的预测功能块 ,在减少总线网络的通讯量的同时 ,更加合理的利用了控制系统中分散在各个现场设备中的资源。通过具体的实验表明 ,预测功能块不仅在减少网络负担方面有非常出色的效果 ,而且可以起到第二传感器的作用 ,应用前景非常广阔。

Design and Realization of Foundation Filedbus Prediction Function Block

One of the important methods in improving the determinism of industrial Ethernet field bus lies in the decreasing the amount of communication data in the Fieldbus network.Based on the analyses of Foundation Fieldbus high-speed Ethernet (HSE),a brand new prediction function block is proposed,which reduces the amount of communication data in the Fieldbus network and more importantly, more reasonably utilizes the resources distributed in each individual device of the control system.Experiments show that prediction Function Block not only has very positive effects in alleviating the network burden,but also acts as a second sensor in the system.Wide application prospect is predictable.
