针对煤矿网络建设单一化、单主机系统无热备份功能以及双机热备启动时间长等原因导致重要数据丢失的问题,提出一种新的网络建设方案和针对不同系统实现热备份功能的新方案。实现了煤矿网络热备份、系统快速热备份功能,保证了煤矿各类系统的正常运行。该方案主要从煤矿工业冗余环网建设、系统主备机工作原理等方面进行阐述。试验表明:方案可以实现网络热备份、系统快速热备份功能,降低了双机热备启动时间,保证了煤矿安全监控系统的正常运行和安全生产。
Aiming at the problems of single data network construction, single host system without hot backup function and long standby time of double hot standby, which lead to the loss of important data, a new network construction scheme and a new scheme of hot backup for different systems are proposed . It realizes the hot backup of coal mine network and the rapid hot backup function of the system to ensure the normal operation of various coal mine systems. The program mainly from the coal industry ring network construction redundancy, the main work of the system prepared to explain the machine and so on. The experiment shows that the scheme can realize hot backup of network and fast hot backup of system, and reduce the start-up time of dual-system hot backup, ensuring the normal operation and safety production of coal mine safety monitoring system.
