Design Of The Prison Monitoring And Management System Based On RFID Technology

As the administrative organ of prisoners,its main function is to prevent prisoners escape,and its discipline,to avoid endangering society.In recent years,traditional management methods exist management negligence and loopholes,and the prisoner situation is more complex,and a large number in prison.If there is no good supervision and early warning,it is easy to jailbreak,violent prison and other events.Once these events happen,it will cause a lot of waste of manpower and material resources,and affect people's lives.Therefore,intensive study of prison personnel monitoring management system is still of great significance.In this paper,based on the intensive study of monitoring and management system of the prison staff in our country,combined with the actual situation of China's prison,aiming at the problem of low positioning accuracy and difficulty in management,and slow updating information,the application of RFID technology in prison integrated monitoring intelligent management system.The system consists of active tag,remote RFID reader and management terminal.The identification area of the reader covers the entire monitoring area,the personnel position information is updated in real time,and the TCP/IP protocol is used to upload the location information to the management terminal in time.STM32F107 is used as the master chip of the personnel positioning system,and DP83848 is chosen as the Ethernet physical interface device.RF chips using highly integrated n RF24LE1 and n RF24L01+ chips.Based on the comparative analysis of several widely used positioning algorithms of RFID technology,combined with the characteristics of prison monitoring system,select relatively simple RSSI positioning algorithm.It achieves personnel positioning prison monitoring system combined with three side ranging.In this paper,the algorithm is used to analyze the error of ranging results for a single reader and the parameter correction,positioning accuracy is increased by 2.17% on average,as high as 4.54%.The system has the basic functions of personnel information management which is related to input information of prisoners and guards and prisoners,the administrator of classified management,system management whose main role is to the system database,client and other systems for self-repair and maintenance,location management which is real-time monitoring record location of all personnel in the prison area,classified management which is to achieve light criminal and felons regional management with access control,so as to avoid the conspiracy to escape and electronic consumption which is to combine RF tags with electronic consumption in the prison area to avoid cash flow.The experimental results show that the system can meet the design function,have good real-time capability and stability,can be achieved on the prison staff and inmates of the real-time monitoring,can update location information in real time,achieve intelligent monitoring.
