1. Raising the problem
After the 9.11 incident, governments of various countries have increased their security management efforts at airports, and it is especially important to strengthen the detection of airport personnel entering the airport’s safe passages. As the saying goes, house thieves are difficult to prevent, and the occurrence of the 9.11 incident illustrates this point.
At present, the traditional method of identifying people inside the airport is that each person wears a badge with his own photo, and his name and number written on it. When entering the safe passage, the passage security personnel compares the information on the badge to make a decision Whether the visitor is legal or not. The biggest disadvantage of this method of identification is that the badge is extremely easy to forge. In addition, there are many people who come out nearby, and the security personnel are familiar with it, and it is easy to cause negligence. The clothing dedicated to airport personnel is more likely to be forged It is reported that the terrorists of the September 11 incident swaggered into the plane through the safety passage of the internal personnel of the airport wearing the uniforms of the pilots.
Therefore, it is necessary to adopt an automatic identification system to strengthen the security inspection and management of the internal passages of the airport.
There are many types of automatic identification systems:
(1) Barcode
(2) Magnetic card
(3) Contact IC card
(4) Non-contact IC card (1-3 cm)
(5) Fingerprint recognition
(6) Image recognition
(7) Key password
(8) Proximity sensor read-only card (about 10 cm)
(9) Remote sensing read-only card (no multiple identification or only 2-3 cards can be identified at the same time)
(10) Long-distance Census® proximity card with multiple identifications (up to 55 cards can be identified at the same time)
We know that people in the internal passages of the airport are very frequent. If you want all the internal personnel to remove the card on the chest and then shake it in front of the card reader, it will cause great inconvenience to the staff and also affect it. Traffic speed.
Is there a means that can achieve the purpose of automatic identification, but also make the airport internal personnel acceptable, so that they feel that after adopting the new identification method, there is not much change for them? At the same time, this automatic identification method should also satisfy The following conditions:
(1) With direction recognition and judgment function
(2) Can recognize up to 15 proximity cards at the same time
(3) When a person passes through the passage, the nearby card reader can automatically sense the card carried by the person, so the sensing distance is not less than 2 meters
Two, the solution
Use CR1A-DS card reader and TC6A proximity card. Each person hangs a TC6A proximity card on the chest. When the person is near the passage, the induction antenna installed on the passage ground receives the signal of the proximity card and transmits it to the card reader. The card reader reads the card number of the card and passes The Wiegand interface of the card reader is transmitted to the nearby controller. The controller judges the legality of the card. If the card is legal, it outputs a door open relay signal and the green indicator light connected to it is on; if the card is illegal, it outputs an alarm relay signal and the red indicator light connected to it is on. At the same time, the controller also transmits the received card number to the computer in real time, and the photo of the person corresponding to the card is immediately displayed on the computer for the security personnel to manually compare the photos of the passers-by.
The system adopts the network version structure, and all data is stored on the server on the local area network. In order to ensure the security of the data on the server, the server adopts dual hard disk mirroring backup. Once the working hard disk is damaged, the other hard disk can be started to work in the shortest time.

Three, product characteristics
CR1A-DS card reader has the following features:
(1) 3 meters card reading distance
(2) Can recognize up to 55 proximity cards at the same time
(3) Two separate antennas can be connected externally, with two separate outputs (each output has Wiegand and RS232)
(4) With the function of direction recognition (judgment). There are 16 working modes to choose from (you can download the English manual of working modes online www.smartkey.net)
(5) Low battery alarm (Note: The software is optional, the software of the standard product does not include this function)
TC6A proximity card features (compared to other Census? proximity cards)
(1) Light weight, suitable for personnel
(2) Replaceable battery, battery life is generally 3 years. The battery is the standard model CR2025, which is available in the market
(3) A standard PVC card can be inserted
(4) 3 meters distance, with multiple recognition functions of up to 55 cards
System composition

(4) Software
Four, system description

1. A total of 8 personnel entry and exit channels, each channel is equipped with a four-door controller and a CR1A-DS remote card reader with direction recognition, and each entry and exit person carries a remote sensor card TC1A or TC6A When an employee enters and exits the channel, the remote card reader automatically recognizes the remote proximity card carried by the employee (the employee does not need to show the card when he enters and exits the channel), and automatically judges whether the employee is in or out.
2. Each controller is connected with an infrared through-beam sensor, a green indicator light, an audible and visual alarm, an alarm cancel button, a visitor pass button and an arm/disarm switch.
3. When the card is illegal or the person who does not carry the card tries to break into the channel immediately behind the legal person, the infrared beams installed on both sides of the channel will detect an illegal intrusion signal and transmit it to the controller.The controller sends out an audible and visual alarm
4.Each controller is connected to the computer through the 485 bus
5. Configure a card issuer to facilitate personnel issuing cards. The card issuer consists of a single-door controller and an EC1A short-range card reader.
6. The sensing antenna of the long-distance card reader is buried under the channel, about 4-6cm away from the ground. The size of the antenna is a rectangle of 3×1.5 meters. Two antennas are buried in the front and back. The distance between the two antennas is 2-3 meters.
7. The card reader, controller, and power supply are all placed in an iron case. The distance between the chassis and the antenna is no more than 15 meters.
8.Using Ximark company channel management software, you can monitor the entry and exit of personnel in each channel in real time
