Underground wireless attendance realized by wireless sensor network and radio frequency identification

An underground wireless attendance system is designed based on radio frequency identification and wireless sensor network technology. The advantages of wireless sensor network have been applied in the attendance system, mainly solving the problems of wiring complexity and error-prone information collection, among other issues in the current attendance system. This system consists of radio frequency information acquisition module, wireless transmitting and receiving modules, and an attendance information processing system. After a long-term practice test, this system demonstrates stable performance and achieves the performance and functional requirements proposed in the design stage. The wireless attendance system has broad application prospects.
