Use your mobile phone to lightly scan the QR code on the bicycle to unlock the bicycle. So how does the mobile phone unlock the bicycle?

With the development of the Internet and the popularity of smartphones, bicycle sharing, as a new way of travel, has brought great convenience to people and solved the problem of the last mile of travel. You only need to lightly scan the QR code on the bicycle with your mobile phone to unlock and use the exclusive bicycle, which is very convenient. So how does the mobile phone unlock the exclusive bicycle?

***There are three most common ways to unlock bicycles, namely mobile communication unlocking, Bluetooth communication unlocking and purely mechanical unlocking. There is no integrated circuit module in the bicycle lock that uses a purely mechanical unlocking method. It is just a device similar to a luggage combination lock. Each vehicle has a specific number and password.

When people scan the QR code with their mobile phones, the mobile phone background will retrieve the password of the bicycle and send it to the mobile phone. Enter the password to unlock the bicycle. Since the password of each bicycle is fixed, once you remember the password, you can skip the step of scanning the code to unlock and directly enter the password to unlock. Therefore, this unlocking method allows a large number of bicycles to be privately occupied, which in turn creates a problem of bicycle enjoyment. Increase in operating costs.

Early mobile communication unlocking was achieved by sending text messages. The smart lock of ***Xiang Bicycle integrated a SIM card with an independent number. When using the mobile phone APP to scan ***Xiang Bicycle When you click on the QR code, the mobile phone will send the unique number information of the car to the backend, and the backend can query the location and status of the car.

After confirming the unlocking command, the cloud server will send an unlocking text message to the SIM card of the car. After receiving the text message, you will hear the motor in the car lock rotate and the lock sheath "pop" One sound, unlocking successfully.

The advantage of SMS unlocking is that the unlocking success rate is relatively high, unlocking does not require GPRS/3G traffic, and it saves power. However, its disadvantage is that the unlocking time is relatively slow. The reason is that after issuing the unlocking command, you still need to wait for the delivery of the text message.

With the development of technology, ***Bike Company is actively seeking cooperation with communication companies to develop new unlocking methods. I believe that in the near future, the innovation and upgrading of ***Bike unlocking technology will be Bring us a more convenient, more stable and safer use experience.
