摘要
基于煤矿井下应急救援的需求,提出了多环境参数实时监测系统设计方案,实现对井下瓦斯、风速、氧气、温度、一氧化碳等环境参数的实时采集、传输与控制。该装置由救护队员随身携带,采用SDSL点对点宽带连接技术,利用电话线进行数字信号传输。0.5 mm线径的电话线在2 km的距离内可以达到1.5 Mb/s的速率,提供了一种可实时监测事故现场环境参数的技术手段。该系统同时采用便携式可充电锂电源、全数字时刻联机接入设备、救援用快速布线盒等实现矿山救援"即铺即用"的组网技术。
A design of the multi - environment parameter real - time monitoring is proposed on the basis of coal mine emergency rescue,gas, wind speed, oxygen, temperature and carbon monoxide can be collected, transmitted and controlled. The equipments are carried by rescue workers, digital signal is transmitted by point - to - point broadband access technology and with telephone line. Telephone line of 0.5mm diameter can be reached 1.5Mb/s rate. It can provide a real - time monitoring of the accident site enviromental parameters technological means. The system also using portable, rechargeable lithium power source,all-digital time online access,and rapid rescue wiring boxes, to realize rapid network technology of mine rescue.
