1. The working principle of the system
This system integrates automatic identification technology, computer network technology and projection technology to form an integrated system for meeting automatic registration.
The label worn by the conference delegates is called a representative card. It is a non-contact IC card with a frequency band of 13.56M and supports the protocol ISO 15693. The original TI chip is used to ensure long-distance recognition and stable performance.
The card reader used in this system is a new generation of high-frequency radio frequency automatic identification system developed by Shanghai Zhuyan Electronic Technology Co., Ltd. Its working mechanism is: each tag has a 64-bit global unique ID identification number. When the electronic tag enters the sensing range of the reader, the electronic tag is activated by the electromagnetic interrogation signal continuously emitted by the reader , So as to feed back to the reader a response signal carrying the ID number and data. It is through the signal inquiry and response between the electronic tag and the reader that the reader can accurately and quickly identify the electronic tag carried The ID number and data of the electronic tag, and the read ID number and data of the electronic tag are output to the computer, external controller or other terminal equipment in a certain output format, so as to realize the identification of the electronic tag.
There are 2048 bits of data storage space in the electronic tag, which can be used to store some basic information of the representative, so as to avoid storing all data in the back-end database, increasing the burden and instability of the system. As long as the representative wears the representative card, go everywhere Going to a meeting, even if the background database is different, as long as it is a legal reader, the basic information of the representative can still be read, which is not possible with the current ID card.
When a representative wearing an electronic tag comes to the entrance of the check-in terminal, the nearby card reader will pass the read ID number of the electronic tag to the check-in terminal through RS232 (485 or wireless), etc., and the check-in terminal will pass the computer network to the check-in terminal. The data (the ID number of the electronic tag read) is transmitted to the remote computer server. In this way, the check-in terminal and the query terminal connected to the server can update the data in real time: the check-in terminal displays real-time information such as the photo and name of the channel representative, and the query terminal displays the real-time situation and statistical data of the meeting report in real time, such as the number of people, The actual number of people and the number of people who have not arrived.
2. The composition and introduction of each part of the system

The system is divided into four main parts, a back-end server statistics and management system, which is divided into a card issuing subsystem, a venue management subsystem, and a front desk sign-in subsystem.
1. Special non-contact IC card for conference
This system uses 86*54mm long-distance non-contact IC card for conferences, which has the characteristics of high recognition rate, long recognition distance, and repeatable reading and writing. Contactless IC card, also known as radio frequency card, is a new technology developed in the world in recent years. It adds radio frequency transceiver circuit on the basis of CPU card. It successfully combines radio frequency identification technology with IC card technology. , It solves the problem of passive (no power supply in the card) and contact-free, which is a major breakthrough in the field of electronic devices. Compared with the contact type IC card, the non-contact type has the following advantages:
1) High reliability
There is no mechanical contact between the non-contact IC card and the reader, avoiding various failures due to contact reading and writing. For example: failure due to rough card insertion, non-card foreign object insertion, poor contact caused by dust or oil stains, etc. In addition, there is no exposed chip on the surface of the non-contact card, and there is no need to worry about the chip falling off, electrostatic breakdown, bending damage, etc., which not only facilitates the printing of the card, but also improves the reliability of the card.
2) Easy and fast operation
Due to the non-contact communication, the reader can operate the card within 10cm, so there is no need to insert or remove the card, which is very convenient for users to use. The non-contact card has no directionality when it is used, and the card can be read and written by swiping in any direction to complete the operation, which greatly improves the speed of each use.
3) Anti-collision
The non-contact card has a fast anti-collision mechanism to prevent data interference between the cards. Therefore, the reader can “simultaneously” process multiple non-contact IC cards. This improves the parallelism of the application and virtually increases the speed of the system.
4) Can be suitable for a variety of applications
The storage structure characteristics of the contactless card make it multi-purpose with one card and can be used in different systems. Users can set different passwords and access conditions according to different applications.
5) Good encryption performance
The serial number of the contactless card is unique, and the manufacturer has solidified the serial number before the product leaves the factory and cannot be changed. A two-way verification mechanism is adopted between the contactless and the reader, that is, the reader verifies the legitimacy of the IC card, and the IC card also verifies the legitimacy of the reader. The non-contact card must be mutually authenticated with the reader three times before processing, and all data is encrypted during the communication process. In addition, each sector in the card has its own operating password and access conditions. Because the radio frequency card has the above incomparable advantages, it is also suitable for electronic wallets, automatic highway toll collection systems and automatic bus ticketing systems.
According to the characteristics of the conference, the card is designed as a two-in-one card for portrait ID card and radio frequency IC card. The card base material is made of PVC material, which is beautiful, generous and durable. The front of the beautifully printed commemorative or iconic pattern of the card base is printed with the photo, gender, name, position and other information of the participants through the card printer. The card usage rules and precautions can be printed on the back.
2. Barrier-free meeting sign-in channel
This system uses the YN HFT11 long-distance channel barrier-free RFID sign-in machine of Zhuyan Company, which combines advanced infrared recognition technology and long-distance RFID recognition technology. The system can automatically identify the member’s identity when the participant passes through the sign-in channel , And judge whether to enter or exit the venue, so as to realize automatic conference sign-in and comprehensive management of personnel entry and exit. At the same time, it can judge the status of one person with multiple cards, no card entry, and multiple people with one card. At present, all non-accessible conference sign-in systems on the market cannot identify the direction of participants entering and leaving the conference venue.
Features:
The sign-in process is quick and convenient. The sign-in personnel only need to put the sign-in card on their chest and pass through the channel at a normal speed (even if it is a fast pass) to complete the sign-in.
Stable performance. This device can support all-weather long-term use without any performance drift problems.
The recognition rate is high. This equipment adopts high-performance antenna design, and the recognition rate of the sign-in card can reach more than 99%.
Easy to install. This equipment is designed with a large number of integrated technologies, with a simple structure and easy installation;
It can intelligently identify people without a card, and has an intelligent anti-tailing function.
It has two working modes: infrared direction recognition and non-infrared direction recognition. In the infrared direction recognition working mode, the device can recognize the direction of the sign-in person in and out of the venue, but only one person can sign in through the channel at a time, and multiple people cannot sign in through the channel at the same time. In the non-infrared direction recognition work mode, the system does not recognize the entry and exit directions of the sign-in personnel, but the device supports multiple people to sign-in at the same time, which greatly improves the sign-in speed.
Infrared direction recognition and non-infrared direction recognition working mode, the operator can manually switch according to the actual situation of the on-site sign-in flow, to meet the fast and smooth progress of the sign-in.
The equipment parameters are as follows:
