Remote fault analysis platform of coal mine monitoring system

For problems of low time-efficiency of fault process, heavy on-site maintenance workload and high cost of operation and maintenance of coal mine monitoring system, a remote fault analysis platform of coal mine monitoring system was designed based on unified specification of fault information. The platform is divided into device layer, network layer, system layer and operation and maintenance layer. Fault probe with self-diagnosis capability is built into the device layer. After fault is detected by the fault probe, relevant information is cached and uploaded to the network layer. The network layer caches the fault information from the device layer, and then packs and uploads it to the system layer with the fault information generated by the network layer. Fault information acquisition software deployed in the system layer can obtain fault information from upper computer software of monitoring system by means of memory interface, database or text file. Meanwhile, it supports direct acquisition of fault information of equipment in the network layer and transfers the cached fault information to the operation and maintenance layer. The operation and maintenance layer stores received fault information into fault information center library for analysis and push. The platform can provide important data support for fault analysis of coal mine monitoring system and effective technical support for operation and maintenance of coal mine monitoring system.
