Integrated Mine Wide Automation System Based on GEPON integrates surface information management system and subsystems of monitoring and control for mine environment, automation control and communication for coal production together by high-speed Ethernet ring and automation software. It really realizes integrated management and control of mine wide.
 
 
Functions of the System
Multiple software interfaces (OPC, DDE, ODBC, FTP) integrate all the subsystems, it realizes integrative management and control of coal mine wide.
With B/S structure and based on IE browser, the client terminals can be of zero configuration.
Based upon reserving functions and characteristics of each subsystem, it can coordinate all subsystems working in optimum condition, and with strict safety authorization every workstation can control any devices of the surface and underground in the system.
It has functions of data inquiry and statistic, historical curve display, report forms printing, gradual alarm, graded management of data system, fault-alarmed record and complete event record, etc.

With powerful functions of graph configuration, it can display dynamic graphs of each subsystem in group or divided screen in real-time.
Features of the System
The system can transmit multiple signals of industrial TV, safety monitoring system, production monitoring system and IP dispatching and communication system at the same time by 1-core optical fiber.
By the communication mode of upward broadcasting and downward TDM, each ONT (Optical Network Terminal) can have maximum 100M bandwidth for dynamic flow, ensuring information exchange in real-time and transmission quality in good.
Two redundant modes of double Bus lines and ring not only ensure reliability of the system but also flexibility of the networking.
ONT is convenient for operation and easy for maintenance by plug and play.
Each OLT has 4 Ethernet ports of 1000M which can be connected with 10 ONTs, each ONT has multiple 10/100M Ethernet ports.
By passive optical branching technology, single ONT failure does not break running of the whole system, thus ensuring good features of explosion-proof and anti-interfering and stable running.

The network structure of GEPON is adapted to tree-like distribution of laneway of coal mine.
