How does QR code turnstile work and what are the features of QR code turnstile?
In recent years, with the continuous demand of the security market, convenient carrying, and acquisition, QR code has quickly become one hot spot in the industry of turnstile gate recognition.
How the QR code turnstile gate is opened.
Today we are going to talk about how the Mairs’s QR code turnstile gate is opened. (The principle is not complicated)
In the related technology, in the campus, the amusement park, the subway station and so on management, in order to realize the personnel flow control, generally sets the turnstile gate at the entrance and exit, one kind of swipe card type gate, needs the magnetic card to carry on the identification, the magnetic card processing is complex, the cost is high, and carries inconvenient, easy to lose, has brought many inconveniences to the user.
In addition, the turnstile’s switch circuit of the existing gate is complex, the cost is high, and it is easy to break down, which affects the access of personnel.
In view of the shortcomings of the existing technology, Mairsturnstile proposes a gate control system based on QR code turnstile scanning recognition, which is based on QR code information recognition. It solves the problems of high cost and inconvenient use of the existing swiping card turnstile ;
The turnstile gate switch adopts an electronic switch, the circuit is simple, the opening and closing efficiency are high, it solves the problems of the before existing turnstile gate is complex, high cost and easy to break down.
QR code recognition:
At the present stage, the QR code recognition we usually touched is divided into the following several classifications, which is also distinguished from the output format of the signal:
1. Wiegand signal output;
2. Serial port signal output;
3. Usb signal output;
Among these three kinds of output, USB output is more common in the application of two-dimensional code, Wiegand signal is less (Wiegand signal is often used for access control), the serial port signal output is widely used in embedded (professional hardware). So How does QR code turnstile work and what are the features of QR code turnstile?
The above is a brief introduction of QR code turnstile recognition, the specific principle of signal differentiation, we don’t offer too much explanation about this.
I noticed that actually, the QR code with Wiegand output which only in the access control industry has the application, in other industries application is very few. Why does this happen now?
Let’s take a look at the QR code turnstile access gate’s control panel.
A red circle part (WG1/WG2) in the picture is the Wiegand output signal, because our swing turnstile gate is usually used for swiping card recognition.
Using QR code to identify is to modify the signal output of the QR code scanner to Weigand interface output. This scheme is very economical compared with the dedicated industrial control computer, but it involves a problem of QR code generation and distribution.
There is content in each QR code. How to generate the irregular QR code, print it or share it with the mobile phone, and then give the authority to open the gate, the problem of QR code generation and distribution. (This problem can be solved through secondary development docking at this stage.)
Looking back on the development of intelligent turnstile gate access control, the iteration of new technology gives birth to different forms of access control, from birth to now can be divided into password access control-card access control- biometrics access control-mobile phone access control-fusion access control. The emergence of mobile phone access control is a milestone recognized by the industry. It breaks the ability boundary of the original access control. Through the smart medium of mobile phones, the intelligence will be brought to the extreme, among which the most representative is the QR code access control.
Working principle of QR code turnstile:
The QR code turnstile gate is to embed the QR code scanning head in the gate and use the QR code scanning to open the gate to control the staff. Like swiping IC card ID card, and If adding card reader and scanning head together, then can scan QR code and swipe IC or ID card together.
Working principle: the park QR code turnstile intelligent gate is embedded in the QR code scanning head, combined with the QR code electronic ticketing system, the integrated scanning code ticket function module not only enriches the tourism service level but also improves the tourist experience. So that the park to achieve intelligent management has taken a big step forward.
Technical features of QR code turnstile gate:
1. Machine core is composed of special high-speed motor, the door board with fast swing speed, low noise, smooth operation;
2. Adopts the advanced decelerating motor + coding electric control positioning device, efficiently realizes the synchronism when the door board swings, the localization accuracy;
3. The best feature of QR code turnstile gate is speed fast, the speed of opening / closing can reach 0.5 seconds ~ within 1 second;
4. Adopts the special ARM microprocessor as the core technology module electrical control system, the performance is determined and reliable;
5. Has the RS232 standard protocol communication interface, through the computer management system realizes the remote control to open / close the gate machine, may network the operation, may also run offline, realizes the gate machine intelligent management truly;
6. Has the-on self-check, fault self-check and automatic reset function;
7. QR code turnstile gate has the traffic red/green light indication prompt function, causes the access to be quick, accurate, safe, relaxed;
8. Has strict anti-tail with alarm function and anti-reverse illegal traffic function to ensure the legitimacy and effectiveness of traffic;
9. Has anti-clamping function, when the door board in the process of closing the door, someone / object blocking / trailing / forced punching card is clamped by the door board, the door board will immediately force to open, prevent clipping personnel, and constantly sound and light alarm warning, Until the person / object leaves the passage, the door board will automatically reset to ensure the safety of passage;
10. Has the fault self-check and alarm prompt function, causes the problem to solve becomes high efficiency, easy;
11. A variety of mode options, the gate can choose one-way/two-way, swipe card in/out, swipe card out/free card in/out, fast pass/open function and other modes, to meet the needs of various occasions;
12. After the card reading is valid, the door board automatically opens, and when the QR code turnstile gate detects that the person / object has passed the infrared sensing area, the door board automatically closes immediately;
13. Free passage after power off.
Features of QR code recognition
Follow we will check the features of QR code recognition, let’s go to know it again.
The accuracy of QR code recognition is 100%.
For face recognition access control system, it is synonymous with advanced technology access control in our general consciousness, but face recognition’s accuracy can not reach 100%. Because the face system is judged by comparing face features, because the face information collected through the camera can not be 100% the same, the system intelligence thinks that you are “very similar” to a face in the feature library. You will be judged to have access. Please note: I used the keyword “very similar” rather than “yes or sure”.
On the other hand, the QR code turnstile access control system, its recognition process essentially analyzes the QR code, which belongs to the digital picture of machine identification. The two colors of the QR code represent the “0” and “1” of the computer language respectively.
Therefore, the access control system can accurately identify the information on the QR code, once successfully identified, the accuracy can reach 100%. If the information of the QR code is incomplete because of the light reason or the QR code information, it will be indicated that it can not be recognized, but after the face recognition system is successfully recognized, it may appear that it is not himself.
The authority of QR code access control is flexible and controllable.
We know that there are two forms of QR code: static and dynamic. The content of the static QR code will not change. Dynamic is an editable QR code form. At the same time, it makes the dynamic code technology in-depth research and development further, through the unique technology, through the management platform can flexibly set the rights of QR code, such as access time, right of access to the entrance, ladder control rights, effective code scanning times, etc. This can maximize the security of QR code passage and the control ability of access personnel.
Remote Access right for Visitors.
For visitors, in addition to mobile access control, other identification methods can not achieve remote intelligent services, and QR code access control perfectly solves this problem. Through the direct application of the visitor’s mobile phone, or the direct invitation of the internal personnel, the visitor will receive a short message containing the QR code passage certificate, through check the QR code link can enter and exit the corresponding occasion.
At the same time, QR code access control also has the function to remote control door’s opening, through the mobile phone can remotely control access control, such as for friends, delivery guy open community access control.
The QR code becomes a building passport.
During working hours, stepping into the office you will pass through a number of entrances and exits: lobby gate — elevator hall — elevator — company gate — office — conference room — warehouse… If these access controls are card-controlled, then the manager will eventually fall into the lost card – make cards – lost card this vicious circle. If you go in and out of these scenes through face recognition, it may be expensive and unexpected, such as: one day because you are in a bad mood, no makeup, may lead to face recognition failure, make your bad mood worse.
The QR code access control is very suitable for the construction of the whole office entrance control system. A mobile phone can pass through the entrance and exit of the whole building, and visitors can also enhance the visitor experience by authorizing the corresponding entrance and exit authority. For example, visitors enter the gate by scanning the code, enter the elevator scan code to open the ladder permission, at the same time, the elevator button automatically lights up, send visitors to the destination floor, and finally sweep the code into the company, the mobile phone becomes a unified pass mark in the whole process.
