摘要
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。
To the single network construction of coal mine, single host system without hot backup function and double machine hot for a long time, lead to problems such as loss of important data, propose a new scheme of the network construction and high available for different system function. Hot backup, implements the coal mine network system has the function of hot backup, to ensure the normal operation of all kinds of coal mine system. The scheme is mainly from the coal industry redundant network of construction in mine, elaborates the working principle of the system for machine Lord, etc. Experiment shows that this scheme can realize the network has hot backup function and system has the function of fast hot backup, greatly reduces the double machine hot standby time, effectively guarantee the normal operation of the coal mine safety monitoring system, guarantee the production safety of coal mine.
