摘要:
随着现代化煤矿的要求及无线通信技术的发展,地面无线通信技术开始应用于煤矿井下通信。本文从煤矿井下灾害环境的特殊性及救援工作的安全性、紧迫性出发,通过分析W iF i短距离无线通信技术,提出了基于W iF i技术建立一种新的煤矿井下应急救援无线通信系统,重点介绍了其原理、硬件设计和软件仿真。该系统在灾后煤矿井下电力供应完全切断的情况下,仍能迅速建立应急救援无线通信链路。该系统基于S3C2410X ARM9硬件平台,硬件设计主要包括采集终端设备和链路路由设备两部分,可实现井下事故现场的环境参数监测、数据实时传输、语音通信等功能。通过NS2离线事件仿真器对系统仿真结果可以看,出该系统的时延小、抖动率低,传输速率随着时间的增加呈现稳定增长趋势,理论上基本满足井下应急救援通信需要,且性能比较稳定。
Abstract:
Along with modernized coal requirements and wireless communication technology development, the ground wireless communications technology used in coal mine underground communication began. Since the underground mine special environment and the safety and urgency of the rescue, a mine emergency rescue wireless communications system，based on the WiFi, is proposed in this paper. Mainly introduces the principle, software and hardware design simulation. The system can establish a emergency rescue wireless communications link rapidly after the electricity supply completely cut off when the emergency occurred. Part of the underground radio link by underground rescue base, wireless transmission link part, acquisition terminal and cloth device more parts. From the communication technology terms, the system should be wired communications technology and wireless communication technology combining rescue communication system. This system based on S3C2410X ARM9 hardware platform , and the hardware design includes acquisition terminal equipment and link routing device. Underground also to prevent the recurrence of accidents and rescue personnel to provide the personal safety of a good protection. Offline event emulator NS2 right through the system simulation results can be seen, out of the system Delay small, low jitter, With a transmission rate of the increase of steady growth trend, theoretically meet the basic underground emergency communication needs, and performance more stable.
