A Psychiatric Patients Tracking System

Abstract

This paper presents an RFID based psychiatric critical to psychiatric patient treatment. The work of tracking patient tracking system in a psychiatric patient care center. In psychiatric patients must include recording patients' location. this system, RFID Field Generators and Readers are installed RFID devices which are useful, small and cheap are of high in the environment, near the entrance and exit points for prominent to be used in tracking psychiatric patients. Due to tracking the patients. Every patient is required to wear the tag. current RFID techniques for tracking dynamic moving When a tag receives the call from a Field generator, it responds objects, several reasons which could usually cause the to a Reader with the ID of the Field generator issuing the interference and miss detection are (1) the interferences of calling. Based on the Field Generator IDs a tag responds, the signals from two Field Generators of overlapped cover location of the patient associated with the tag can be approximatio helyetimated. Byssociatedowing o t h the pagcatben ranges and (2) the interference of signals from close tags. In appoxmaelyesimted B s dong nt olyth paiet' our paper, we would propose an algorithm to solve it. moving patterns can be recorded but also the event of the o patient leaving the main gate of the care center be detected.In recent years, several researches have been conducted from hardware and software perspectives on the Besides the localization issue, in this paper we also employed a study ofro hrelabi andteardersigntbase on ree Graphic Coloring approach for solving the interference caused from Field Generator located one near another. Experimental space architecture [2] [3] is a major approach from hardware results show that this algorithm has significantly improved the perspective. Experiments have shown that the performance reliability of the tracking system. of a passive RFID system, due to its limited operating range, can be degraded significantly due to morphology distortion.
