ZigBee-Based Monitoring System for People with Mental Disabilities

Abstract

People with mental illnesses are group of people who need special care and constant attention. Although their abilities to think and control their actions are limited - or may be disabled, they still can move easily and don’t stick to their places where they are assumed to be. Thus, there is a substantial need to be aware of their locations to guarantee their safety. For that, an indoor monitoring system based on location determination was designed especially for hospitals and treatment centers. The system exploits ZigBee technology to enable patient’s monitoring. The location of each patient was determined using artificial neural networks through the received signal strength measured from ZigBee transceiver attached to each patient. Results are displayed on a pre-uninstalled map and are stored together with relative important information about each patient in a secured database. The system was able to localize patients at room level in real time with accuracy of 97%.
