矿井宽带无线传输技术研究

提出了矿井宽带无线传输技术是解决采掘工作面移动监控、监视和语音通信需求的关键技术。提出了矿井宽带无线传输应满足传输带宽宽、便于接入有线宽带网络、中继设备少、体积小、发射功率小、电磁兼容性好、安全性好、传输协议标准化、电源电压波动适应能力强等要求。提出了漏泄通信不能用作矿井宽带无线传输技术,但可用于煤矿井下局部通信等;感应通信不能用作矿井宽带无线传输技术,但可用于煤矿井下救灾通信等;透地通信不能用作矿井宽带无线传输技术,但可用于煤矿井下避难硐室等应急通信;小灵通、CDMA、GSM、Bluetooth不能用作矿井宽带无线传输技术;RFID不能用作矿井宽带无线传输技术,但可用于煤矿物联网、矿用设备管理和防碰撞等;ZigBee不能用作矿井宽带无线传输技术,但可用于煤矿井下人员、胶轮车、电机车等动目标精确定位和矿用传感器无线传输等;UWB不能用作矿井宽带无线传输技术,但可用于煤矿井下生命探测、防碰撞、煤矿井下人员和胶轮车等动目标精确定位等;WCDMA、CDMA2000、TD-SCDMA等3G不能用作矿井宽带无线传输技术,但可用于煤矿井下语音移动通信等。提出了矿井宽带无线传输技术宜采用WiFi,4G有可能成为未来矿井宽带无线传输技术。

Research of mine wireless broadband transmission technology

The paper put forward that mine wireless broadband transmission technology is a key technology to meet with requirements of mobile monitoring,video and voice communication on cutting face,and proposed that mine wireless broadband transmission should meet with requirements of wide transmission bandwidth,easy to access wired broadband network,a small quantity of repeater equipments,small volume,low transmission power,good electromagnetic compatibility and safety,standardization of transmission protocol,strong adaptability of fluctuation of power voltage.It presented that leakage communication cannot be used as mine wireless broadband transmission,but as underground local communication;induction communication cannot be used as mine wireless broadband transmission,but as underground rescue communication;through-the-earth communication cannot be used as mine wireless broadband transmission,but as emergency communication of underground refuge chamber;PHS,CDMA,GSM and Bluetooth cannot be used as mine wireless broadband transmission;RFID cannot be used as mine wireless broadband transmission,but as coal mine Internet of Things,mine-used equipment management and anti-collision;ZigBee cannot be used as mine wireless broadband transmission,but as wireless transmission for mine-used sensor and precision location for moving targets such as underground personnel,rubber-tyred vehicle and electric locomotive;UWB cannot be used as mine wireless broadband transmission,but as underground life detection,anti-collision and precision location for underground moving targets such as personnel and rubber-tyred vehicle;3G such as WCDMA,CDMA2000 and TD-SCDMA cannot be used as mine wireless broadband transmission,but as underground voice mobile communication.It proposed that mine wireless broadband transmission technology should use WiFi and 4G would become future mine wireless broadband transmission technology.
