煤矿综合无线局域网WLAN的高效、可靠性设计

Design of High Efficiency and Reliability for Integrated WLAN of Coal Mine

针对传统的煤矿信息网络存在功能分散、成本高、建设周期长、可靠性差等不足,提出了煤矿WLAN高效、可靠性设计的原则和一种基于IEEE802.11协议的煤矿综合无线局域网架构。该架构可在同一网络上实现数据、语音和视频等煤矿综合信息的传输和交换,有效降低网络建设成本,提高网络可靠性。该设计采用煤矿自动化信息网和通信网物理层相互隔离的方式,从而保证煤矿自动化信息网的安全。

Aim at defects of traditional coal mine information network such as functions＇ decentralization, high cost, long establishing period and bad reliability, this paper presented the design principle for high efficiency and reliability of WI.AN of coal mine and a framework of integrated WLAN of coal mine based on IEEE802. 11 standardized protocols. This framework can realize transmission and exchange of integrated coal mine information of data, voice and video on one network, so it can reduce establishing cost and increase reliability of network effectively. The design used insulated method each other between physical layers of coal mine automation information network and communication network, so it ensured safety of coal mine automation information network.
