【摘要】：监狱作为管理犯人的行政机关,其主要功能就是防止犯人逃脱,并对其进行管教,避免危害社会。传统管理方式存在管理上疏忽和漏洞,并且在监狱中,犯人情况比较复杂,人数众多。若没有很好的对其进行监管与预警,可能发生越狱、暴狱等事件。这些事件一旦发生,就会造成大量的人力与物力的浪费,对人们的生活造成了影响。因此,深入研究监狱人员监控管理系统具有极大意义。本文在对我国现有监狱管理的实际情况进行研究,针对定位准确度低、管理难度大和信息更新不及时等问题,将射频识别技术应用于监狱综合监控智能管理系统中。系统主要由有源电子标签、远距离RFID阅读器和管理终端组成。阅读器的识别区域覆盖整个监区,人员位置信息实时更新,采用TCP/IP协议将位置信息及时上传至管理终端显示。采用STM32F107作为主控芯片构成人员定位系统,并选择DP83848作为以太网物理接口器件;射频芯片采用高集成度的nRF24LE1和nRF24L01+芯片。对目前应用较为广泛的基于RFID技术的几种定位算法进行比较分析,结合监狱监控系统特点,选取技术相对简单的RSSI定位算法,并结合三边测距实现监狱监控系统的人员定位。利用该算法对单个阅读器测距结果进行误差分析及参数修正,定位精度平均提高2.17%,最高可达4.54%。该系统实现的功能有——人员基本信息管理:在押犯人有关信息的录入,对于犯人、狱警和管理员分类管理;系统管理:其主要作用就是对系统的数据库、客户端等系统进行自检修复与维护;定位管理:实时监控记录监区内所有人员的位置;分类管理:利用门禁实现对轻、重刑犯分区域管理;电子消费:在监区内将射频标签与电子消费两者相结合,避免现金流通。实验结果表明该系统能够满足设计的功能,具有良好的实时性和稳定性,能够实现对监狱工作人员及所关押犯人的全方位、实时的监控,实时更新位置信息,实现智能监控。
[Abstract]:As an administrative organ for the management of prisoners, the main function of prisons is to prevent prisoners from escaping, to discipline them and to avoid harming society. There are administrative omissions and loopholes in traditional management methods, and in prisons, the situation of prisoners is relatively complex. There are a large number of people. If there is no good supervision and warning, there may be prison breakouts, prison storms, etc. Once these incidents occur, they will cause a lot of waste of human and material resources, which will have an impact on people's lives. It is of great significance to deeply study the monitoring and management system of prison personnel. This paper studies the actual situation of prison management in our country, aiming at the problems of low positioning accuracy, difficult management and information updating, etc. The RFID technology is applied to the intelligent management system of prison integrated monitoring and control. The system is mainly composed of active electronic tag, remote RFID reader and management terminal. The identification area of the reader covers the whole prison area, and the personnel position information is updated in real time. The position information is uploaded to the management terminal to display in time by using TCP/IP protocol, the personnel positioning system is constructed by using STM32F107 as the main control chip, and the DP83848 is chosen as the Ethernet physical interface device. The RF chip uses nRF24LE1 and nRF24L01 chips with high integration. Several localization algorithms based on RFID technology are compared and analyzed. Combined with the characteristics of prison monitoring system, a relatively simple RSSI location algorithm is selected. The algorithm is used to analyze the error and modify the parameters of a single reader. The positioning accuracy is increased by 2.17 on average, and the highest can reach 4.54. The functions of this system are as follows: the basic information management of personnel: the input of relevant information for prisoners, the classified management for prisoners, prison guards and administrators; System management: its main function is to repair and maintain the system's database, client and other systems; position management: real-time monitoring and recording the location of all the personnel in the prison area; classified management: the use of access control to achieve light, In order to avoid cash flow, the experimental results show that the system can satisfy the designed function, and has good real time and stability. It can realize the omni-directional and real-time monitoring of prison staff and prisoners, update the location information in real time, and realize intelligent monitoring.
