　　IoT RFID automatic meeting sign-in system

　　1. Demand Background

　　The Internet of Things RFID automatic conference sign-in system is a statistical and detailed record of conference information, unified management of conference participants, and timely and accurate statistics of attendance, lateness, early departure, absence and other conference states.

　　This system optimizes the inefficiency of traditional manual sign-in, the congestion of card sign-in, and the omission of gate sign-in, and integrates the advantages of traditional sign-in methods. Participants only need to carry small tags and leave everything else to their hands. The system can enter and exit the conference from any path, and the system can count the meeting status of the participants such as being late, leaving early, and not participating.

　　2. Application introduction

　　The IoT RFID automatic conference check-in system adopts low-power wireless RFID technology and has the following characteristics:

　　1. Stability Guarantee

　　The system adopts long-distance automatic identification technology, and adopts a special Internet of Things solution, which has strong anti-interference ability and ensures accurate check-in.

　　2. Real-time statistical supervision

　　The labels of the participants regularly report their own information, and the participants' participation status can be known in real time during the meeting.

　　3. Emergency help

　　The label is equipped with an emergency help button. When the participants encounter an emergency, they can send a help signal to the system to solve the problem that they cannot get help due to unexpected situations due to too many people.

　　4. Long working hours

　　The small label adopts ultra-low power consumption technology and can work for more than half a year, avoiding the repetitive document production of multiple meetings.

　　3. Equipment introduction

　　1. RFID tags

　　As shown in Figure 1, each participant needs to carry one, which can be used for more than half a year, and there are various color choices.

　　Figure 1 RFID tag

　　It can be hung on everyday portable products, such as mobile phones, keys, computers, wallets, etc. It is portable and compact. It is required to bring it when attending a meeting. The size is 36mm×36mm×5.8mm.

　　2. Card Issuer

　　Figure 3 Schematic diagram of the card issuer

　　The card issuer is connected to the computer card issuing software through the USB interface, and the ID information of the label is bound with the personnel information during the card issuing process.

　　3. Mini base station

　　Figure 4 Schematic diagram of mini base station

　　Depending on the size of the conference room, different numbers of mini base stations are configured. Generally, a conference room with less than 500 people is equipped with 1~2 mini base stations. The base station is installed in a way that can be moved at will, just insert the plug into the 220V socket, and try to choose a high plug. The mini base station will receive the signal from the RFID tag. After the base station receives the data, it can be sent to the background system through Ethernet or WIFI for remote statistical supervision.

　　4. Handheld viewing

　　Figure 5 Handheld PDA

　　Considering that there is no network at the conference site or there is a sudden problem with the network, the handset can be used as a temporary base station to receive RFID tag information, and then connect to the background database through 3G.

　　When a participant sends a request for help, but cannot accurately know their location, a handheld mobile phone can be used to assist in search and positioning.

　　4. Software effect

　　Figure 6 Information registration interface

　　For managers to issue cards and bind information to participants in a unified manner. After registration, participants do not need to register each time.

　　Figure 7 Sign-in statistics interface

　　Managers can easily view the real-time venue situation from the background system, including information such as those who should arrive but did not arrive, those who are late, and those who leave the venue in the middle.

　　Figure 8 Alarm processing interface

　　As shown in Figure 8, when an alarm event occurs, there will be a message prompt at "Alarm Processing" in the menu bar; after entering the processing interface, the system will be classified and displayed according to "different alarm contents, and the administrator can selectively select according to the degree of urgency. Processing; click the "processing" button at the back of the message, and the alarm disappears, which means that someone is going to deal with it.
