Visitor Management System Design And Implementation

This visitor management system is a second generation citizen ID card as a voucher for entry and exit.In order to make it convenient for outsiders to visit the Internet of things laboratory of the college,it is also convenient for the management of the college laboratory.Specially designed a highly automated access control system.According to the latest statistics from the Ministry of Public Security,the number of second-generation ID cards has now exceeded 1.2 billion.Because of the particularity and reliability of the information contained in the second generation ID card,at the same time,database technology and network technology are used to store and query the certificate information,and the advantage of using it as the entry and exit certificate is very obvious.Using this scheme to replace the current market access control system,the application prospect is very extensive.The design principle of this visitor management system is based on the Internet of things technology,combined with Ethernet technology,mainly including the application of TCP/IP protocol and RS485 communication technology,in addition to the embedded micro-control technology,etc.A new access guard visitor management system based on second generation ID card is proposed.The visitor system uses the second generation ID card as the access guard card,because the second generation ID card belongs to the contactless IC card,it has the contact IC card with large storage capacity,is not easy to be magnetized,and the information is not easy to copy and lose.The card has the advantage of longer service life.The other two generations of ID cards have integrated a microprocessor chip.The processor chip is a national patented product.The manufacturer of the intelligent chip is appointed by the Ministry of Public Security and the whole process of production is strictly controlled.At the same time,the intelligent chip of the second generation ID card is difficult to imitate technically,and its security degree is very high,so the security of the entrance control system using the second generation ID card as the key card is high.This visitor management system only needs to authorize the user ID card in advance,and the operation is very simple,so it does not need to issue another card,realizes the multi-use of one card,and saves social resources.The visitor management system includes the Internet of things control system,which is used to record the second generation ID card information of visitors,the management server software system,and the terminal monitor controller part,which is mainly used to control the access guard switch.In addition,there are voice broadcast function module and image acquisition module composed of four parts.Access control management,video monitoring,voice intelligent warning and alarm,attendancefunction.This paper analyzes the design of visitor management system.
