In And Out Of Campus Management System Based On Internet Of Things Technology Research

Along with the social economy and the rapid development of science and technology and Internet technology,more and more applied to various industries,especially the identification and security industry,at the same time in and out of campus management system as the main application of the intelligent building system is more and more be taken seriously.In and out of the traditional campus management adopts mechanical lock and credit card,require close operation,a lot of moment are very convenient,and prone to all kinds of problems,the cost is higher also.The rapid development of the Internet of things technology fills such defect,and radio frequency tag is contact,have fast reading and writing ability,low power consumption advantages.Based on the above background,this paper designs a kind of application of RFID technology in the campus and advanced management system,realize when personnel and vehicles in and out of campus each gate,the system will automatically obtain identity information to determine whether in personnel and vehicles for normal access to personnel and vehicles,and detailed information recording personnel and vehicles.At the same time of illegal access and send out alarm signal and stop the vehicle in and out.At the same time made the access management system and the next bit machine communication protocol,the serial port debugging program,has realized the management information,such as application data download to the read-write device and put the records of the read-write device uploaded to the PC.And the collision of the RFID system problems puts forward a new algorithm,dynamic tree RFID collision algorithm by leaps and bounds.This system adopts the uhf RFID card,support ISO18000-6B agreement by RFID read-write device decoding and the identity of the card information via a serial port/wireless communication module to service stations,service stations for through the Internet network,to implement the items of the hardware architecture of the Internet.Major hardware design includes LPC2378 main controller and AS3992 UHF rf chip,RFID read-write device of a series of functions such as data transmission and label storage full system implementation scheme,and improved the existing way of application of improved application performance.Software according to the characteristics of this topic application system analysis Outlines discrepancymanagement PC software data entity,and connect with each other between the entities,and design the form at the same time show that data entity;Using Microsoft Office Access database and application software,VB language to write the upper machine adopts modular designed by the method of setting the human-computer interaction interface,can be achieved in and out of campus management,statistics,and duration in and out of the information query function.By means of system development and black box testing,validation of this system can realize the functional and integrity.But reliability,scalability,and there are deficiencies,such as mass production can be written more practical control interface and add database,make the function of in and out of campus management system has a more rich.
