摘要

摘要: 目前用于煤矿井下的信息承载网主要是百兆、千兆和万兆矿用以太环网，其时延和可靠性不可控，难以满足煤矿井下少人或无人作业、地面远程控制等需求。服务质量（QoS）可保证最高优先级应用的实时性和可靠性，但当多路接口信号同时汇入且数据量较大，或前１个数据包正在发送时，最高优先级应用的实时性和可靠性也无法保证。针对上述问题，提出了煤矿智能化信息综合承载网技术要求：传输带宽宽、传输时延短、可靠性高、传输距离远、抗干扰能力强、本质安全防爆、电网电压波动适应能力强、抗故障能力强、防护性能好、多业务综合承载等。基于上述要求，提出了基于灵活以太网（FlexE）的煤矿智能化信息综合承载网，根据时间敏感和时间不敏感视频、时间敏感和时间不敏感音频、人员定位、车辆定位、设备定位、安全监控、供电监控、运输监控、排水监控、采煤工作面监控、掘进工作面监控等不同业务对带宽、时延和可靠性的需求，分配不同的信道，将煤矿监控、定位、视频和音频等多网合一。基于FlexE的煤矿智能化信息综合承载网既满足了地面远程控制、人员定位、安全监控等不同业务对带宽、时延和可靠性的需求，又实现了煤矿智能化信息一网综合承载，减小了维护难度和工作量。

Abstract: At present, the information carrier network used in coal mine is mainly 100 Megabit, Gigabit and 10 Gigabit mining Ethernet ring network. The time delay and reliability of the network are uncontrollable. Therefore, it is difficult to meet the needs of few people or unmanned operation in underground coal mine and remote control on the ground. Quality of service (QoS) can guarantee the real-time performance and reliability of the highest priority application. However, the real-time performance and reliability of the highest priority application can not be guaranteed when multiple interface signals are imported at the same time and the data volume is large, or when the previous data packet is being sent. In order to solve the above problems, the technical requirements of coal mine intelligent information comprehensive carrier network are proposed. The requirements include wide transmission bandwidth, short transmission delay, high reliability, long transmission distance, strong anti-interference capability, intrinsically safe explosion-proof, strong adaptability to grid voltage fluctuation, strong anti-fault capability, good protection performance, multi-service comprehensive carrying, etc. Based on the above requirements, a coal mine intelligent information comprehensive bearing network based on flexible Ethernet (FlexE) is proposed. This network allocates different channels according to the requirements of different services on bandwidth, time delay and reliability. The businesses include time sensitive and time insensitive video, time sensitive and time insensitive audio, personnel positioning, vehicle positioning, equipment positioning, safety monitoring, power supply monitoring, transportation monitoring, drainage monitoring, coal working face monitoring and heading face monitoring. The network integrates coal mine monitoring, positioning, video and audio into one network. The coal mine intelligent information comprehensive carrier network based on FlexE not only meets the requirements of different services such as ground remote control, personnel positioning and safety monitoring for bandwidth, delay and reliability, but also realizes the coal mine intelligent information comprehensive carrier network, reducing the maintenance difficulty and workload.
