高速公路收费系统的高可用性设计及实现

针对高速公路收费工作的连续性和稳定性要求,设计开发了高可用性收费站管理系统。在硬件架构方面建立了双机热备系统,在软件架构方面利用管理模块对其它模块的监控,实现了软件自主恢复功能。软硬件故障测试表明,系统故障恢复时间控制在10s以内,满足了实际要求。

High Application Design and Realization of the Toll System of Expressway

Aiming at the continuity and stability requirements of expressway charge,the management system of high availability toll station is designed and developed.Hot standby system is established in hardware structure and other modules are monitored by management module at software,which realizes the self-recovery function of the software.The fault tests of software and hardware prove that the recovery time of system failure controlling within 10s satisfies the actual requirements.
