Improved safety management system of coal mine based on iris identification and RFID technique

It used to be difficult to precisely understand the situation of miners underground according to the existed miner safety management system. To solve this problem, we propose an improved safety management system based on iris identification and RFID (Radio Frequency Identification) technique. It combines several modern identification and communication techniques such as iris identification, RFID, computer networks and database technique. Iris identification technique is used to identify the miners by the physiological characteristics of iris and specific database for every individual is build to record the precise attendance information. Moreover, RFID is used to realize real-time tracking miners underground. Practical results show that the improved miner safety management system is able to count the number of miners underground exactly and on time, providing the reliable and useful information for daily miner management and emergency rescue. The improved system has high quality of reliability, veracity and security.
