A ZigBee and RFID hybrid system for people monitoring and helping inside large buildings

This article refers to a system that combines ZigBee and RFID technologies for monitoring people behavior when moving inside a building. The RFID part of our system consists of a set of detector placed at strategic points. To accomplish this detection goal the visitors of the building have to be provided with a RFID tag either active or passive. The ZigBee wireless subsystem will send the information generated by the detectors to the main computer. The movements of all and every one of the attendees will be followed on-line and recorded in a database. Filed information will be useful to know people activity and performance afterward. The system also includes an artificial intelligent program (a planner) that would be used to direct the movements of visitors when necessary, for instance, in case of fast evacuation of the building for fire or earthquake.
