REAL TIME MONITORING & ANALYZE OF HAZARDOUS PARAMETERS IN UNDERGROUND COAL MINES USING INTELLIGENT HELMET SYSTEM
ABSTARCT :
Coal mining has always been a necessary evil. We need the coal for various operations, especially electrical power generation. However mining the coal has proven to be very dangerous and has caused many accidental deaths over the years. Keeping this in mind we have designed an intelligent system which can be used on helmets of these underground coal miners and can monitor/analyze a few major hazardous parameters found in these mines in real time. This includes humidity, temperature and gas contents such as methane and sulfur dioxide. These parameters, if above a certain level, can cause choking, suffocation, flooding, gas poisoning, roof collapse or explosions. Our system can detect these parameters, analyze them in real time and alert the ground control and the worker about the situation using a buzzer. Compact sensors and radio frequency modules are used to ensure practicality.
EXISTING SYSTEM :
? This is a mechanical mixture of gases existing in a mine after an explosion of firedamp or coal dust. Its composition is extremely variable, but usually includes carbon monoxide, carbon dioxide, nitrogen and sometimes H2S and SO2 with a very small percentage of oxygen.
? In any network multiple router may exist. It can relay signals from other routers or End point signals. It can never sleep either.
? In any network multiple end point may exist. It can’t relay signals. It can sleep to save power.
? The framework must decide if a mineworker has supported an existence undermining damage.
DISADVANTAGE :
? Main consideration lies in the improvement of safety issues of workers, whether it is coal mining or other minerals.
? The real time monitoring system helps in measuring the physiological variables and the environmental variables which may cause health issues to the workers.
? The gases present in coal mine environment are harmful and may cause serious issues to the health of the worker when reached beyond the safety value.
? As a precaution a continuous real time monitoring of oxygen saturation, gases present in environment, heart rate and ambient temperature is important.
PROPOSED SYSTEM :
• They proposed an overhearing-based adaptive data collecting system, which makes use of the redundancy and the correlation of the sampling readings in both time and space to ease the traffic and control.
• It makes the implementation of mine monitoring systems essential for the safety purpose.
• The real time monitoring which is the requirement now a days is designed for the purpose.
• They purposed a solution suitable for mine wireless communication, and safety monitoring using this scheme.
• Gas is transmitted from the purpose of unearthing, as well as from the coal being transported to the surface.
ADVANTAGE :
? A performance test of the proposed system was conducted in an underground limestone mine.
? When the subjects used a smartphone-based personal PWS, scores on mental demand, time demand, physical demand, frustration, effort, and overall performance were all higher than when using a smart helmet-based personal PWS.
? A performance evaluation was conducted at an actual underground mine site to evaluate the performance of the personal PWS developed in this study.
? If the workload is not properly adjusted when designing the system, overload can occur, and the work efficiency can be reduced.
? Therefore, it is necessary to improve the work efficiency by designing and operating a system with minimal workload.
