基于LONWORKS~控制网络的企业数据集成系统模型研究

Data Aggregation Model of Enterprise System Integration Based on LONWORKS~ Control Network

网络根据应用对象的需求和特点的不同,可划分为数据网络和控制网络两大类。数据网络是以数据传递为目的,实现信息共享的网络,包括互联网络,通信网络等;控制网络是以传递控制和状态数据为目的,实现分布控制的网络。正是由于两种网络的应用对象不同导致了他们在网络的实现技术上的很大差别,涉及到OSI/ISO七层协议堆栈的各个层面。其结果是由于网络协议的不同,数据网络和控制网络的完全隔离,造成资源和信息的浪费。例如,目前许多企业的ERP系统还只停留在对信息流的管理,对制造过程中的控制流数据缺乏分析,不能充分发挥企业投入巨资上马的ERP系统的能力。建立数据网络和控制网络之间的桥梁,实现数据网络和控制网络的无缝隙集成,是构建企业集成应用平台的基础。

According to the featureand requirementof application target, Network can be divided into two categories —— Data Network and Control Network. Data Network is for information sharing, such as Internet and communication network. Control Network is for signaling and statusinterchanging of distributed device. The target difference causesthe implementation technology difference of these two kinds of network from physical layer to application layer refer to the OSI/ISO 7 layers stack. The result is isolation of Data Network and Control Network, waste of resource and information, no energy saving and efficiency. It is the premises to seamlessly integrate the Data Network and Control Network for entire enterprise application, ERP or CRM etc.
