Abstract: In order to solve problems of disordered underground material management, delayed and inaccurate information of material consumption and wasted labour, an underground material management system based on mine Internet of things was designed. Internet of things architecture of the system was given and function module design of the system was described. Material information collected from working environment is obtained by active RFID tag and intelligent handheld terminal, and uploaded to data sever through WiFi gateway. The data is processed in the server and stored in database, and the processed data is accessed, processed and displayed by Web technology. Therefore, real-time monitoring and management of life cycle of underground material can be achieved.
