【摘要】：射频识别(Radio Frequency Identification RFID)技术是一种非接触式通信技术,通过使用射频电子设备发射频率信号,射频信号经过空间耦合来自动识别目标对象并获取相关信息。RFID有许多优势,如非接触、自动识别、速度快、实时、防水、防磁等。近年来,小学校园频发冒领、丢失、坏人闯入、绑架、杀人等安全事件。尽管小学校园安装了监控设备,但没有识别和预警功能,故不能及时采取措施加以避免。小学生活泼好动,自我保护能力弱,有时会跑到园内危险区域,造成伤害。另外,小学校园门禁主要通过保安对纸质通行证的辩别进行管理,坏人容易乘虚而入。因此,本文设计一种更有效的小学校园安防管理系统,即将RFID技术应用到安防管理系统中,以确保小学生在校期间的安全。本文通过对RFID技术在小学校园安防系统应用模式的研究,构建了基于RFID技术的小学校园安防管理系统。第一,给出小学校园安防管理系统的总体设计目标,建立了基于RFID技术小学校园安防系统应用模式和工作流程。第二,分析定位算法与防碰撞机制,本系统采用的定位算法为区域网格定位算法,选取了本身具有防碰撞机制的器件。第三,在安防系统的硬件设计中,读写器采用模块化设计方法,实现了小学生、家长、园内工作人员所配戴的电子标签的读写功能,并将标签中的信息发送到上位机。第四,采用RS485串行通信技术实现读写器与上位机通信。第五,以SQL Server 2005为后台数据库,采用C#开发上位机管理系统,设计了窗口、控件和函数,并利用C#继承性与封装性,简化了程序代码。本文采用无线射频识别技术改变了小学校园安防管理仅依靠保安的局面,既提高管理效率,又能实时定位,危险区提前预警,杜绝安全事故的发生,而且方便小学生与工作人员的考勤管理,非常适用于小学校园安防管理。
[Abstract]:Radio frequency identification (Radio Frequency Identification RFID) is a kind of contactless communication technology. By using radio frequency electronic equipment to transmit frequency signals, radio frequency signals can be automatically identified by spatial coupling to obtain relevant information. (Radio Frequency Identification RFID) has many advantages, such as non-contact. Automatic recognition, high speed, real-time, waterproof, magnetic proof and so on. In recent years, the primary school campus frequent occurrences, lost, bad guys break into, kidnap, killing and other security incidents. Although the primary school campus is equipped with monitoring equipment, it does not have the function of identification and early warning, so it can not be avoided in time. Pupils lively and active, weak self-protection, sometimes ran to the dangerous area of the garden, resulting in injury. In addition, primary school entrance control mainly through the security of paper pass management, bad people easy to take advantage of false entry. Therefore, this paper designs a more effective security management system of primary school campus, that is, RFID technology is applied to the security management system to ensure the safety of primary school students. In this paper, the application mode of RFID technology in primary school campus security system is studied, and the primary school campus security management system based on RFID technology is constructed. First, the overall design goal of the primary school campus security management system is given, and the application mode and workflow of the primary school campus security management system based on RFID technology are established. Secondly, the location algorithm and anti-collision mechanism are analyzed. The location algorithm used in this system is the regional grid location algorithm, and the devices with anti-collision mechanism are selected. Thirdly, in the hardware design of the security system, the reader adopts the modular design method to realize the reading and writing function of the electronic tags worn by pupils, parents and staff members in the garden, and sends the information from the tags to the upper computer. Fourthly, RS485 serial communication technology is used to realize the communication between the reader and the host computer. Fifthly, taking SQL Server 2005 as the background database, using C # to develop the upper computer management system, the windows, controls and functions are designed, and the program code is simplified by using the inheritance and encapsulation of C #. In this paper, radio frequency identification technology is used to change the situation that the security management of primary school campus only depends on security, which not only improves the efficiency of management, but also can locate in real time, early warning of dangerous areas, and put an end to the occurrence of safety accidents. And convenient attendance management of primary school students and staff, very suitable for primary school campus security management.
