What types of shared bicycle locks are there?

In daily life, everyone will use shared bicycles, and most of them will encounter the problem of unlocking when using shared bicycles. With the advancement of time and the maturity of technology, the unlocking methods of shared bicycle locks are becoming more and more diverse and mature. So what changes have the shared bicycles experienced from the beginning to the present, and what types of shared bicycle locks are there? Let me briefly share with you below.

1. Pure mechanical

At the very beginning, everyone must know a lot about the ofo small yellow car, and the ofo small yellow car used a purely mechanical unlocking method at the beginning. The user scans the QR code, obtains the password through the mobile phone software, and manually turns the dial. , to achieve unlocking. There is no technical point, the traditional combination lock, and it is a dial type, after use, you need to manually disturb the combination dial, otherwise it can be considered to be open all the time.

2. Bluetooth communication

The principle of bluetooth unlocking is that the user can communicate with the bluetooth module in the bicycle smart lock through the mobile phone bluetooth, and send the information to the server side, the background management system sends the unlocking command to the app installed in the user's mobile phone, and the user's mobile phone receives the background information. After the command of the management system, the Bluetooth of the shared bicycle is unlocked through the Bluetooth of the mobile phone.

In addition, the Bluetooth chip can also obtain the real-time location information of the shared bicycle by sharing the GPS positioning of the mobile phone, and transmit the information to the cloud platform. After the instruction is given, the Bluetooth of the shared bicycle is controlled and unlocked through the Bluetooth of the mobile phone.

3. IoT module

When we use a shared bicycle, we can scan the code with our mobile phone and click the "unlock" button to unlock the car. After we are done using it, lock the shared bicycle. Without having to operate on the mobile phone, the system can also judge that we have finished using the bicycle. These functions are mainly realized through the Internet of Things technology.

In the process of the user scanning the code to unlock the shared bicycle lock. The user scans the code to enter the system of the shared bicycle cloud. The system will record the identity (ID) of the user and the identity (ID) of the vehicle.

Simply put, the system needs to know who used that bike. Record the user ID for subsequent payment. To record the vehicle identity id, the cloud system needs to send an "unlock instruction" to the shared bicycle through the GPRS network.

The cloud system completes the "instructions" issued by the communication server, while the shared bicycles receive the instructions issued by the communication server through the communication module installed inside.

This communication is bidirectional, and the system can issue commands to unlock the car. When the user automatically locks the car after use. The communication module also uploads the vehicle status to the system. The system will calculate the cost incurred by the user for using the bicycle.

In general, as the technology becomes more and more mature and modern, the way of unlocking tends to be more intelligent, convenient and safe. At the same time, it is hoped that more convenient and safe unlocking methods will appear in the future.
