Abstract: This article introduces the various functions of nursing home management system based on Internet of things, describes the RFID personnel positioning principle, the fall detection principle, the principle of health monitoring sensors and their implementation. Through inputting the identification number of elderly and other information in RFID tag, when the elderly carries it and passes a checkpoint, the system can determine the position of the elderly, and uses gravity acceleration sensor to collect the acceleration waveform as the basis for fall detection.

Key words: Internet of things, RFID technology, personnel positioning, health monitoring, fall detection
