Reliability Research Of Mining Industrial Ethernet Based On Optical Fiber Communication Technology

Along with the calculator technique, network technique, communication technique continuously developed, for satisfying the request of modern coal mine safe production and information management, many single supervision function system must be replaced by strong function the whole coal mine integrated supervise and control system .It turns towards the standardization, network and intellectualized direction .The text corresponds by modern communicate technique and the coal mine concrete environment and present according to kilomega industrial Ethernet fiber optic delivers system.Through the system feasibility analysis,comprehensive performance testing and proof by experiments,it was suggested that the transmission of security monitoring information on the Industrial Kilomega Ring—Type Ethernet was efficient and reliable .The system is much better than traditional copper or fiber network of analogue transmission system in other transmission capacity,capital and operating costs. The research result shows that the information isolation problem is solved effectively by information sharing,functionality complementing and integrated application in the system.It can monitor production procedure and ensure production safety.Mine and office automation network connect seamlessly in the system.Firstly in the article it's based on the requirement of coal mine, built mining optical fiber communication system; Secondly it's presented a design of Industrial Ethernet based on the optical fiber, and study adaptive routing according to the ants calculate way; Thirdly it's carried on a research on self-healing character ,and compare with different self-healing ring network; The fourth elaborate two major types of The Survivability Technologies: protection and renew, and excellence and shortcoming, and it's necessary to carry out the multilayer survivability; Finally lead the concept of membership cloud, it's establishment misty valuation model of multi-function appearance complicated system reliability, and made use of the mode to carry on reliability analysis with the mining Industrial Ethernet.
