Abstract: Aiming at the relatively serious delay problems easily caused by disadvantage impact such as external environmental limitation,limited range of elimination coverage,decreased system throughput and others in synchronous transmission of coal mine safety monitoring system,this paper proposes an intelligent elimination method for synchronous transmission delay of coal mine safety monitoring system.Through multi-stage congestion location sensing capture technology,it breaks through the constraints of external environment on delay elimination,sets flexible delay elimination constrained condition for synchronous transmission,and constructs a monitoring system synchronous transmission delay elimination method based on aggregated tree.By using even symmetric response processing mechanism,it effectively eliminates delays and improves the overall performance of the system.The test results show that the throughput of the design method reaches over 8.5 Gbit/s,with relatively high specificity and stability in elimination,which helps to improve the processing effect of transmission delay.
