Coal measurement and control system of dual computer hot standby software design

In view of the shortcomings of the Hot standby scheme of the coal mine Monitor Systems,such as Infexible,high costs,single point of failures,etc..this paper proposaled a solution which based on fexibility,low cost,reliability design discipline,focus on design and implementation of the overall structure of hot standby software, heartbeat detection module,the resource management module and data synchronization module.
