Esign And Implementation Of Coal-mine D Adapter Base On Gas Monitoring System

Gas is main reason of coal mining accidents, about 70% to 80% domestic coalmine accidents caused by gas explosion. With the national security department requirements, gas monitoring system must be installed for every coalmine enterprise. For domestic north-south Environmental huge difference and backward of the technology of gas monitoring system, At present, The features of gas monitoring system inclueds: There are a wide range of gas monitoring systems with confused versions; Poor compatibility between these systems, no standard communication protocols between them; Original data of some gas monitoring systems could be intercepted and modified forced; Gas date will lost if system failed. These phenomenons lead to gas monitoring system is hard to retrive correct gas data quickly, so the risk of gas accidents increased.The coalmine data adapter in this paper is focus on developing a technology to retrieve gas data from data link layer directly through collection algorithm, at the same time, the handler and communication model of coalmine data adapter will filter, rearrange gas data and send these data to web monitor platform immediately with an unified format. If gas monitoring system failed, coalmine data adapter could store gas status and data through real-time store technology and re-send these data to web monitor platform automatically if system recovery.The coalmine data adapter in this paper solves the compatible problems between different gas monitoring systems, provide a technolgy to prevent tamper data mannually and avoid gas data lost when system failed. This solution can produce significant social benefits.Coalmine data adapter develop an advanced collection algorithm to retrieve gas data from data link layer directly and send these data to web platform directly. This technology guarantee the gas data is correct and real, The gas data can not be tampered manually.Coalmine data adapter design an unified format and interface for coalmine enterprises to transfer data via web monitor platform, resolve issues caused by non-standard format and interface in gas monitoring system.Coalmine data adapter implements gas data backup and disaster recovery intelligently without affecting existed gas monitoring system, guarantee contiguity of gas data, could provide integrity of gas data for accident causes analysis.
