Application And Research Of Private Network Wireless Communication In Coal Industry

With the transformation and upgrading of coal industry,most of China’s coal enterprises have constructed and applied a variety of systems of dedicated networks,but with the improvement of coal industry automation,the traditional system of communication system has been unable to meet the development requirements of intelligent management of coal industry,and will be replaced by a new generation of dedicated wireless communication network with high bandwidth and high quality signal coverage.Besides satisfying the most basic functions of voice communication,data transmission and remote monitoring of users,TD-LTE network can also provide other value-added services based on big data bandwidth,fully considering the individual requirements of coal mine enterprises.Compared with other mainstream technologies,TD-LTE has many technical advantages,such as stronger anti-jamming ability,better signal quality,higher spectrum utilization,more diversified business services and more flexible network supervision.It has been widely used by government,army and enterprises,and has also been used in emergency command and dispatch,special task execution and daily communication services.In the process,it provides reliable,efficient and high-quality communication guarantee for users.At the same time,it also provides a brand-new technical scheme and better choice for coal enterprises which are facing difficulties in operation and maintenance of private networks because of using backward technology to upgrade and transform private networks.In order to meet the development requirements of informationization,intellectualization and transparency of China’s coal enterprise management,this thesis based on the relevant literature research of TD-LTE private network communication system,collates and analyzes the relevant theory and technical knowledge of China’s mining private network construction,and combines with the present stage of China’s coal aviation industry wireless communication technology.This thesis introduces the characteristics and advantages of the technology of TD-LTE,expounds the key technology and related technical scheme of the technology of TD-LTE,and puts forward the overall framework of the wireless private network of coal mine,and puts forward the key links and main parts of the construction of the special network of coal mine from the aspects of network layout and management system.Specific design and implementation plan.Finally,the functional performance test of the implementation scheme is carried out to verify that the design scheme can reach the requirements of coal mine users.Based on the comprehensive analysis of the outstanding advantages of TD-LTE network in terms of communication quality,storage capacity,transmission rate and anti-jamming,this thesis designs the overall framework and implementation scheme of a new generation of coal mine dedicated wireless communication network based on TD-LTE technology,with a view to constructing the underground between the various departments on the well and all underground.The seamless communication system between operators provides technical support for ensuring the safe production of enterprises in an all-round way,and provides technical solutions for coal enterprises to realize the transformation and replacement of mine wireless private network.On the one hand,this thesis enriches and supplements the theoretical development of wireless private network,and at the same time,it also provides a reference for promoting coal enterprises to improve production efficiency and accelerate the transformation and upgrading of China’s energy industry.
