Gepon, Integrated Automation Systems In The Coal System

Coal Mine Monitoring System experienced a process from single monitor to multi-parameter monitor. Domestic 80's since the beginning of the 20th century, Coal Mine Safety and production automation monitoring and control system development basis on the Single machine series .most products have been in coal production and application security. These systems address the needs of the mining mechanization, but most common bad Compatibility and low cost performance problem. Because of various automation systems of different communication protocol resulted in "information island". Incompatible with the common hardware, Net One of the many development trends, Difficult to meet the high-yield, efficient, safe production requirements of Coal enterprises.To address these issues, the current required to set up a mine-wide integrated automation system. System can mine all kinds of monitoring systems will be high-speed backbone network and software platform to integrate automation. The construction of the control signals and data transmission channel and operating platform. System for coal enterprises in the production process control, production operations and production management on the provision of the overall solution. So that managers can keep abreast of coal mine production. Managers can also be an emergency in the event of direct control. System set up to improve the operation of coal mine production, safety, accidents, disasters, forecasting and production business plays an important role in management.This thesis is to address these issues, research, design systems based on coal mine GEPON multi-service bearer platform. And the use of point-to-multipoint network architecture, passive optical transmission, high-speed Ethernet-based platform, TDM MAC MAC midnight, for the coal mine to provide a wide range of integrated services broadband access technology.The main contents are:1. Analysis of existing industrial Ethernet technology, Ethernet, switched Ethernet and GEPON distinction, put forward a GEPON of coal mine based on the multi-service bearer platform framework. 2. Construction GEPON integrated automation of high-speed backbone of information transmission network, integration and transformation of the original automated monitoring of a variety of coal mine monitoring system.3. GEPON dedicated management software used across the network on all network management devices. Unified messaging platform, production and operation management and implementation of office automation and information technology. Eventually improve management efficiency, To provide basic information and supporting analysis tools for business decision-making.4. According to the demand for testing, testing strategies, the development of test cases for system testing.
