A MULTI-CHANNEL INTRINSICALLY SAFE REAL-TIME ENVIRONMENTAL MONITORING SYSTEM FOR UNDERGROUND MINES

摘要

The microprocessor based multi-channel intrinsically safe real-time environmental monitoring system of the present invention will be particularly useful for underground mines. The system of the present invention is capable of providing real-time monitoring of different environmental parameters such as temperature, air velocity, machine status, methane, carbon monoxide at a plurality of locations even in a big underground mine. The system of the present invention enables two-way communication, which is very much essential for taking up appropriate control action whenever required from the surface. The system also provides on-line visual representation of trend of all the monitored parameters and gives audio-visual warning signal when a particular parameter crosses the respective threshold limit so that mine management can immediately take appropriate action. This would also help in enhancement of productivity and profitability of a mine, proper ventilation planning, early detection of fire, indicating occurrence of high concentration of gases, reducing the response time and minimizing dependence on human errors.
