Sensor-controlled emergency/evacuation system for large houses, hotels or a firm's building uses a central recording office for wireless detection of sensors

摘要

A sensor is integrated in an identity/authorization card carried on a person (11) for detecting and locating that person. A building (8) has multiple rooms (9), in each of which there is an active radio frequency identification (RFID) transponder (10) for detecting passive RFID sensors (12) within its detection range.
