Research on upgrading and reconstruction of underground personnel management system in Tang'an Coal Mine
The traditional personnel position monitoring system often has defects such as backward positioning technology and inability to interact with other equipment.In actual use,it has been unable to meet the requirements of modem coal mine intelligence.In view of this situation,this paper takes Tang'an Coal Mine as an example to transform and upgrade the original personnel position monitoring system of the mine.Through the analysis and comparison of the existing personnel positioning technology,the KJ1626J mine underground precise positioning system is selected.The system adopts UWB positioning technology and TOF(time of flight)positioning algorithm,which has the advantages of high positioning accuracy,wide positioning coverage,strong anti-interference performance and multi-system integration.After the practice of the new system,the application effect is good,and the safety production management level of Tang'an Coal Mine is improved.
