Design And Implementation Of RFID Based Personnel Location And Tracking System In Secret Places

With the continuous development of information technology,the problem of loss of confidentiality has become a thorny issue for many secrecy departments.In order to improve confidentiality,many confidential places need to register people entering and leaving the place.The traditional registration method is to use security personnel records and review methods to complete.After the visitor enters the confidential place,there will be Special guards or surveillance cameras monitor the interviewers,but this way there is no way to obtain the location of the interviewers accurately and in time.In order to be able to supervise the visitors at any time,the supervisors need to pay attention to the monitoring at any time,which will Cause greater workload.Targeting personnel in secret places.The paper designs an automatic identification and tracking technology based on RFID technology.The personnel positioning system will mainly consist of readers,positioning tags,communication service base stations and software monitoring systems in the background.Access personnel need to keep this confidential before entering the confidential place The place provides personal information,and the monitoring personnel of the secret place enter the information of the visitor into the corresponding electronic tag.When the visitor enters the secret place,the reader installed inside the secret place can identify the electronic tag and is located in the monitoring room.The personnel can use the monitoring software to monitor the interviewer in the monitoring room.When the interviewer enters a place where the authority cannot enter,the monitoring device will sound an alarm.The RFID-based security personnel positioning system can bring great convenience to the monitoring of personnel in secret places.It is of great practical significance to study the application of this RFID technology in secret places.The innovations of the research work in this paper are as follows: mainly to improve the RSSI algorithm,to explore based on the placement of readers and electronic tags,and innovatively introduce reference tags as a benchmark.The rectangular reference label layout based on the LANDMARC algorithm and the improved isosceles triangle label layout were explored separately.Instead of using the nearest neighbor algorithm parameters in the two layouts for exploration and analysis,the neighbor positioning algorithm was improved after the three-sided distance was obtained.The experimental results It shows that when the nearest neighbor parameter is 5,the two layouts have better results,and the reference label layout based on the triangle is better than the reference label layout based on the rectangle.It has higher indoor positioning tracking performance and less error.Has a certain practical value.
