Problems solved by technology

[0005] B. The theoretical transmission rate of IEEE802.11b / g single-frequency 2.4G is 54Mbps, the uplink port is only 100M, and the maximum throughput is 20Mbps for one-way transmission and 26Mbps for two-way transmission. With the development of underground communication monitoring technology and the increase of equipment , the amount of data to be transmitted is also rising sharply, and traditional wireless switches can no longer meet the needs of modern underground communications
[0006] The intrinsically safe power supply used in the mine has clear requirements on the power consumption of the whole machine and the start-up impulse current (GB3836.4 intrinsically safe explosion-proof standard), and the power consumption of the load equipment is generally not allowed to exceed 18W. Downhole use

Description

technical field [0001] 本发明属于以太网设备技术领域,尤其涉及一种本安型8口万兆双频大功率无线交换机。 Background technique [0002] 煤矿综合自动化是煤矿高产、高效和安全生产的保证,而煤矿井下网络平台是实现煤矿综合自动化的基础;目前,我国的许多煤矿都建立了工业以太网,用于井下采煤装备以及井下环境参数的监控;大部分方案都是采取井下有线以太网方式,布置于主要巷道,不能覆盖整个井下;无法实现运动机电装备的监控,比如采煤机、机车等;我国的煤矿综合自动化项目,均没能涵盖综采工作面,不能实现综采装备的远程监控,于是出现了无线交换机方案来取代有线交换机方式,采用百兆单频无线网络方式(百兆上行+无线百兆下行)。 [0003] 目前井下无线交换机的不足之处主要体现在以下几点: [0004] A、传输速率不高,100兆端口上行通信,下行为只支持IEEE802.11b / g单频2.4G无线设备连接到带有无线收发功能的摄像仪或通信控制设备。 [0005] B、IEEE802.11b / g单频2.4G的理论传输速率为54Mbps,上行端口只有100兆,最大吞吐量最高为单向传输20Mbps,双向传输26Mbps,随着井下通信监测技术的发展和设备的增多,所要传输的数据量也在急剧上升,传统的无线交换机已经不能满足现代化井下通信的需求。 [0006] 井下所使用的本安电源,对整机功耗和启动冲击电流有明确要求(GB3836.4本安防爆标准),负载设备功耗一般不允许超过18W,此要求限制了大部分普通无线交换机在井下的使用。 Contents of the invention [0007] 本发明实施例的目的在于提供一种本安型8口万兆双频大功率无线交换机,传输率高,满足现代化井下通信的需求。 [0008] 本发明实施例是这样实现的: [0009] 一种本安型8口万兆双频大功率无线交换机,包括:电源缓启动模块、本安型DC-DC电源模块、本安二次保护模块、电源管控模块、ARM架构SoC模块、双频无线基带射频模块、存储模块、时钟模块、光口电源管控模块、万兆交换芯片模块、光纤接口模块和RJ45接口模块; [0010] 电源缓启动模块外接电源,电源缓启动模块与本安型DC-DC电源模块连接,本安型DC...
