    A mine intrinsically safe AD hoc network base station design

    • 摘要: 针对灾后矿井下通信链路中断,救援人员信息无法互通的问题,设计1种矿用本安型自组网基站;设备基于SDR平台,采用FPGA+ADIAD9361+本质安全电路的方案,利用无线Mesh网络技术的无线多跳、自组织和强自愈能力,在矿井下供电、通信系统都被摧毁的环境下,能够快速、方便地组建无线通信网络,同时为矿井下的手持终端、矿用布控球、矿用信息记录仪等终端设备提供无线覆盖,实现事故现场与前方指挥部的信息互通。测试结果表明:基站具有自备电源、安全系数高、体积小、质量轻、功耗小等优点,2.4 GHz和1.4 GHz双频段无线组网,多跳能力为视频6~8跳,单跳传输距离大于200 m,单跳传输时延小于7 ms,功耗小于15 W,可连续工作4.5 h,可解决矿山各种事故灾害应急救援过程中遇到的通信问题。

       

      Abstract: Aiming at the problem that the underground communication link of the mine is interrupted and the information of rescuers cannot be exchanged after the disaster, a mine intrinsically safe AD hoc network base station is designed. Based on the SDR platform, the equipment adopts the scheme of FPGA + ADI AD9361+ intrinsic safety circuit, and uses wireless multi-hop, self-organization and strong self-healing ability of wireless mesh network technology to quickly and conveniently form a wireless communication network in the environment of underground power supply and communication system being destroyed, and at the same time, provides wireless coverage for terminal equipment such as handheld terminals, mine control balls, mine information recorders, etc., to realize information exchange between the accident scene and the forward command. The test results show that the base station has the advantages of self-provided power supply, high safety factor, small size, light weight, small power consumption, etc., 2.4 GHz and 1.4 GHz dual-band wireless networking, multi-hop capability of 6-8 hops of video, single-hop transmission distance greater than 200 meters, single-hop transmission delay of less than 7 ms, power consumption of less than 15 W, and continuous work for 4.5 h, which can solve the communication problems encountered in the emergency rescue process of various accidents and disasters in mines.
