一种新型分布式汽车多检测线系统体系结构

A new distributed multi-inspection controlling system architecture for vehicle

针对汽车检测站中多检测线各自独立控制,且功能主要局限于满足工业测控的问题,在对传统汽车单检测线控制系统结构分析的基础上,采用基于组件的软件工程方法和第四代分布式控制系统技术,设计了一种适用于多检测线的新型体系结构,该系统分为过程控制级、集中监控级、数据服务级、管理决策级和用户服务级。应用结果表明:新型体系结构将多条汽车检测线统一控制管理,比传统的单检测线控制模式更能充分利用资源,大幅提高检测站的检测能力;通过对网络结构、物理结构和逻辑结构的优化,不但能实现传统检测线的测控功能,还可将其扩展为集中控制、分散处理、资源共享、面向服务的集检测、控制、管理与服务于一体的综合信息平台。

According to the fact that multi-inspection lines control independently in one vehicle inspecting station, and the function is limited to meet industrial measurement and control, based on the structural analysis of traditional vehicle single-inspection system, this paper designed a new architecture, which was suitable for vehicle multi-inspection lines, by using component-based software engineering methods and the fourth-generation technology of distributed control system. The architecture was divided into the process control level, the centralized monitoring level, the data service level, the management decision-making level and the customer service level. The practice proved that the multi-inspection lines can be integrated with control and management by the new architecture, which takes fuller advantage of the resource than the single-inspection con- trol mode and dramatically improve the inspecting ability for inspecting station. By optimizing the network architecture, physical architecture, logical architecture, the new architecture not only can achieves the traditional functions of measurement and control, but also can integrate centralized control, distributed processing, resources sharing and service oriented into an information platform, which combines the functions of inspection, controlling, management and service. 4 figs, 12 refs.
