Preface
Vein recognition is a recognition technology that uses near-infrared rays to read the vein pattern, compare it with the stored vein pattern, and perform personal identification. DUOAO uses this technology to use near-infrared photography from a position away from the recognition device, and compare it with pre-stored vein patterns to perform identity recognition.
Chapter 2 Solution
2.1 System overview
In this plan, we designed a system that uses the non-contact palm vein as a voucher, combined with the current world’s advanced computer technology and network technology, to control elevator users and elevator use time.
Elevator building control management: Its main function is to use non-contact palm vein intelligent recognition to restrict specific personnel from entering and exiting the elevator, so as to prevent casual people from entering and exiting at will. You can enter permitted elevators and floors according to authorization during the designated time period. Can inquire, count and analyze access information files at any time. Both real-time control and information management. The system will automatically recognize the advanced biometric technology and the motherboard to manage the safety of people entering and exiting the elevator.
2.3 Solution
2.3.1 Brief description of the system
System mode: direct access by swiping card, using password to take the elevator, non-contact palm vein automatic identification layer control mode
The elevator access control system is composed of a controller installed in the elevator hall, an IC card installed in the management center, an IC card held by the elevator user, or a palm vein with authority.
After the IC card issuing center sets the authority for each IC card, the issued card can be used. Different cards can be set with different authority, corresponding to different users; the management IC card held by the manager is usually set to be able to Full authority to use the elevator; for the lost card, the IC card issuing center can report the loss and disable the lost IC card to prevent illegal holders from continuing to use it.
The elevator access control system automatically exits the management when the elevator is in special conditions such as fire protection and inspection, or can be exited through a manual switch. The elevator can be registered without an IC card, which is convenient for the elevator to use in special situations.
It is suitable for environments with higher security levels. Users on each floor are required to swipe their cards to use the elevator, and they can use it normally after confirming their legal identity. Can effectively prevent the illegal entry of idlers.
You can swipe your card, and you can directly use the palm vein.
2.3.2 System Solution
Solution advantages: palm veins, safety, convenience, biometric identification, suitable for high-end properties, bringing a safe and intelligent life to solve the shortcomings of property management;
Disadvantages of the scheme: strict control of elevators will allow some owners to have a certain period of adaptation, which is more expensive;
2.3.3 System technical parameters
Connection between USB palm vein collector and computer
(Note 1) When the USB1.1 interface is connected, normal operation cannot be guaranteed.
Technical parameters of Doao palm vein intelligent elevator access control reader
2.3.4 System function description
Introduction to palm vein recognition column
Features of Palm Vein Recognizer:
Non-contact authentication, simple and natural
Users have no sense of resistance in terms of hygiene
? Especially suitable for unspecified majority of people.
Just extend the palm of your hand for authentication
? Movement is natural and simple.
High precision, high safety, stable characteristics
Compared with other biometric authentication, palm veins have many blood vessels and are complicated
High recognition accuracy
Thick blood vessels and high cold tolerance
Good safety and stability
Because it is an internal feature of the body, it is extremely difficult to forge. The palm vein sensor also has the function of biopsy.
Features
Can be used on the Internet, configure and manage the PC, manage and process data on the networked terminal
Rich interface, integrated network interface, USB port, RS485/Wiegand interface
Built-in IC card recognition to realize 1:1 accurate and fast authentication
Equipped with a touch screen, can operate and maintain without a display
5. Provide authentication record interface, which can be applied to access control, attendance, etc.
Palm vein authentication application case in Japan
In financial institutions that value safety and reliability, starting with Tsuruga Bank in July 2004 and Bank of Tokyo-Mitsubishi (now Bank of Tokyo-Mitsubishi UFJ) in October, it has been widely used in the back office after 6 years of stable usage. (Kawasaki Credit Union), personal safes, etc.
