【Abstract】 The system makes use of GSM SMS(Short Message Service) to transfer data between working stations and controlling center,realizing remote controlling of poisonous air in the working stations timely and aiming at sending alarms before happing of accidents such as explosions.The system takes advantage of an active queue management method called BLUE to solve the problem of data queuing which is caused by multi data arriving at GSM SMS(Short Message Service) at nearly the same time,ensuring that every detecting points’ data can reach the controlling center timely,accept and run the commands which come from the controlling center effectively.更多还原
