空管系统中双机热备份管理的设计与实现

Design and Implementation of the Dual Hot-spare Management in Air traffic Control System

在空管关键系统中,一些双机热备份子系统由于系统检测容错软件本身存在出错的可能性,使得双机热备份系统的可靠性降低。本文介绍了空管系统中基于代理检测的应用级双机热备份系统的设计原理及其具体实现。

In the core of the air traffic control systems some dual hot-spare sub-systems have the possibility of making errors as the result of the fault-tolerant software system itself existing errors, which reduces the reliability of the dual hot-spare system. This paper introduces the design principle and implementation of the applicable dual hot-spare system based on agent detection. The new design is improved on the basis of the original dual management and has the merit of applying the primary spare in process which reaches the function of load balance. It proves the value of wide adoption and realization in other automatic air traffic control systems.
