QR Code Access Control

QR code access control

Wabon Technology QR Code Calling System is an elevator floor registration system based on QR codes and mobile social platforms. Its components include the server: cloud server and QR code scanning equipment in the elevator, and the client: the QR code call menu based on the applet. After registering in this system, users can generate time-sensitive QR codes, which can be used by users themselves or sent to visitors via . The user or visitor carries this QR code and displays it in front of the scanning device in the elevator car to register to the user's landing.

Advantages

(1) User convenience

The QR code call elevator system uses , the most extensive instant messaging platform, and the large number of user clusters makes the system highly applicable. Convenient for your own use and also for authorized visitors: share with visitors via or other methods. At the same time, it also improves the safety of community buildings, reduces the frequency of elevator use, and extends the life of the elevator.

(2) Strong security

The QR code generated by this system is effective and time-sensitive. Validity means that the QR code generated by the system contains dynamic encrypted fields calculated by complex algorithms. It is almost impossible to forge, and the forged QR code will not be recognized by the scanning device. Timeliness means that the QR code becomes invalid after a certain period of time and cannot be used again.

(3) Save material cost

For elevators that require permission to use, IC card calling systems are generally used. The authorization, issuance, and recovery of IC cards require manual labor, and IC cards are damaged, malfunctioning, and other situations that need to be dealt with, which undoubtedly increases management Cost and workload of the party. And this system does not require additional cost, only one mobile phone is enough.

(4) High system matching

The system can be deployed and operated safely on various types of elevators from different manufacturers.

(5) High stability

The system can operate stably 24 hours a day.

(6) High-end user experience

You can register your floor by turning on your mobile phone without pressing a button or swiping your card, giving users a high-end elevator experience.

Functions

Project Includes

1. Cloud server

2. QR code scanning equipment in the elevator car

3. Deployment of QR code system on Mini Program

(1) Cloud server

The cloud server is used to receive user registration data and provide the data queried by the system when generating the QR code. In addition, a MySQL database is deployed on the cloud server to store user data for the entire project. This system is equipped with a cloud server, which is a distributed web application/business development hosting and operation platform. It is a true cloud computing service with high reliability, high expansion, and free operation and maintenance.

(2) QR code scanning equipment in the elevator car

The two-dimensional code scanning equipment is an image capture device, which is embedded in the COP in the elevator car. It can scan the two-dimensional code in front of the equipment in real time and transmit it to the elevator system after interpretation. When the user displays the QR code in front of the QR code scanning device, the device will determine the validity and timeliness of the QR code after interpreting the QR code. After both are passed, the device will directly obtain the QR code. The floor information in the code, and send the floor data to the elevator system to achieve the purpose of registering the floor.

(3) Deployment of the QR code system on Mini Program

Through the secondary development of the applet, the system's QR code menu, front-end page code, and front-end and back-end (cloud server) interaction interfaces are deployed on it, so that users can add the applet to use QR code system. The user needs to register for the first use. After registering, you can get your own QR code on the applet.

Configuration

Cloud refers to the QR code cloud server deployed on the Tencent Cloud platform, which stores the floor information registered by the user and the corresponding user ID. The mobile terminal refers to the applet added by the user, in which the QR code call elevator system menu is deployed. The two-dimensional code scanning equipment in the car refers to the two-dimensional code scanning equipment installed on the elevator COP in an embedded installation mode.
