Design and implementation of gas disaster early-warning system based on hot-standby

In view of problem of single-point failure in hardware and software running environment of gas disaster early-warning system of coal mine,a gas disaster early-warning system based on hot-standby was proposed,and its hot-standby solution,hardware and software design and implementation were introduced.The system employs high-reliability hot-standby cluster for mutual backup and hot-standby solution based on RoseHA and shared disc array,greatly improves its reliability.The application result shows that availability of the gas disaster early-warning system based on hot-standby is greatly improved with longer mean time between failures and shorter mean time for fixing failure,compared with the early-warning system based on single server.
