摘要
针对中小型煤矿双机容灾热备份问题,为保护现有设备投资,节约投资成本,提出了摒弃传统的软硬件相结合的双机容灾热备份方案,采用单纯软件方式实现主备机之间状态侦听、数据发布/数据订阅的双机热备数据同步系统。该系统符合国家相关安全行业标准要求的功能,可以在中小煤矿原有计算机配置基础上运行,既保证安全监控系统的不间断运行和数据的完整性,又节约企业新的设备投资成本。
According to the issue of the double equipment running/standby in the medium and small coal mines, in order to protect the available equipment investment and save the investment cost, the paper provided to give up the traditional double equipment running/ standby plan with the software and hardware combined. A signal software mode would be applied to the double equipment running/standby data synchronous system with the intercept between the running and standby equipments, data issue and data subscription. The system could meet the required functions of the state related safety industrial standard and could apply to the medium and small coal mines with the existing computer devices. The system could ensure the continued operation and the data integrality of the safety monitoring and control system and could save the new equipment investment cost of the enterprises.
