Design And Implementation Of The Campus Security System Based On Internet Of Things

The campus is an important place to carry out the talent education, it is entrusted with the country, society and the hope of every family. Maintaining campus security and stability, but also an important guarantee for the construction of a harmonious society. In recent years, with the continuous expansion of the scale of colleges and universities, the number of teachers and students in the school staff have continued to increase, composition is also more and more complex, the campus theft incidents have occurred from time to time. At the same time, with the development of social economy and improvement of people’s living standards, the government, the society and the family investment in education is more and more big, the property quantity and types of schools and students have more and more. As the school, regularly purchase and add some valuable teaching equipment and experimental instruments, and almost all the students have computers and mobile phones and other valuables, especially things like computers and mobile phones are designed and made increasingly miniaturization. From desktop to notebook computers, and then to the tablet, the appearance of more and more light, more and more portable, it also makes it more vulnerable to theft, property safety problems in this series to security management on campus has brought great challenges.The focus of the traditional campus security system are placed in the "security", but without the "anti" very good, "Ann without anti commonly exists, which is mainly reflected in the current security system, all the colleges and universities are mainly in video monitoring, which in most cases are just as after the event view the lack of the necessary tools, advance warning, stealing occurs also failed to timely detection and treatment, so that even if the campus monitoring probes installed a lot of, but not fundamentally prevent the occurrence of campus theft incident.In this thesis, taking the campus intelligent security as the main research object, and based on analyzing the technology of Internet of Things, I want to talk about the innovation and exploration of the RFID electronic tag chip technology, GSM communication technology, keyboarding, liquid-crystal display, and so on.The main results are as follows:1. Putting forward a campus intelligent security scheme based on the Internet of Things: Items will be stored in the system in accordance with the corresponding information, and be connected to the phone number of the owners. The articles are labeled with RFID electronic tag, once in the scope of the alert system, the system can alarm automatically. Now the security personnel may ask the carriers to show the confirmation message sent by the system to their mobile phones. The master chip used in this system is the microcontroller AT89S52.2. Combined with the technology of the Internet of Things, and by using RFID electronic label chip e5550 with125 kHz working frequency and reader chip U2270 B, we can put the passive tags into the articles which need to be protected, so the reader-writer device can response to the status of them.3. By making a detailed study of the GSM communication technology used to receive and send short message, we can realize the function of sending the special information to the designated mobile phone by the system.4. By using the design of keyboarding and LCD modules, we can improve the interaction of the system and human beings.
