Study on key technology for networking mode of “one net and one station” in coal mine

In order to improve the efficiency of mine communication,sharing and optimal allocation of resources,through the research of “one-stop network project,in the underground communication system using new networking mode,the use of underground exchanger by 10 Gigabit ring network unified access connection and underground safety monitoring,personnel location,emergency broadcast,video monitoring,wireless communication business method to comprehensive communication substation in the effect of field test and test network model to enhance the allocation of resources."A network of a station" project for the first time using a downhole switch connected into a 10 Gigabit ring network structure,the bandwidth increased to 10 Gigabit,and through the “Ring thimble” mode,effectively enhance the data transfer rate;The terminal service is no longer independent transmission,but unified access integrated communications sub-station,through a fiber connected to the ring network switch,to optimize the original system information transmission structure,effectively reduce the mine business repeatability,to achieve the purpose of sharing resources .
