Research And Improvement Of Real-time Information System

This paper analyzes the requirement for the enterprise on the real-time manufacture information system. It puts forward a complete plan which focuses on the support for alien-structure control systems, stability, security, expandability.In order to avoid modifying the main system when adding support to a new type of control system, the plan employs gateway to mask differences among them.To ensure stability and security, the plan handles the situation of data inconsistency carefully. And adopt a deliberate authority mechanism to prevent the system from being attacking.To ensure expandability, the plan designs common interfaces for the modules on which function expanding may required.
