基于4G通信技术的煤矿无线通信系统研究

Study on Coal Mine Wireless Communication System Based on 4G Communication Technology

井下通信系统作为煤矿安全生产的3条生命线之一,越来越多的生产数据都将以此为承载,因此,建设矿用无线通信系统是保证煤矿安全生产的必要手段。分析了现有的无线通信技术,提出了基于4G通信技术的TD-LTE矿用无线通信系统建设方案,该系统严格遵循煤矿井下安全避险"六大系统"中的通信联络系统建设规范,以电信级TD-LTE无线通信设备为基础,进行了针对专网应用的优化,专设了专网独立应用的调度平台,并涵盖了中继、交换、无线、有线、会议、集群、定位、视频、系统设备管理等子系统,可极大提升企业生产管理水平,有助于企业的网络信息建设。

Underground communication system is one of three lifelines of coal mine safety,more and more data are loaded on the underground communication system operation,so the construction of mine wireless communication system is the necessary means to ensure the safety production in coal mine.Analyzed the existing wireless communication technology,the building plan of TD-LTE mine-used wireless communication system was proposed.The system strictly follows the communication of coal mine safety risk 'six system' contact standard construction system,the telecommunication level TD-LTE wireless communication equipment is used as the basis for the optimization of the network application of the needle.Scheduling platform was dedicated for independent network,and this platform covers subsystems such as the relay,switch,wireless,cable,conference,cluster,positioning,video management and system equipment.The application of this system can greatly enhance the production management level of the enterprise,and can help to construct network information.
