What is the principle of shared bicycle unlocking? How does the shared bicycle smart lock work? What is the shared bicycle smart lock architecture? If you ask about the latest trend of the most popular travel mode since 2016, non-shared bicycles are the only ones. For example, OFO shared bicycles, cymbals, blue bicycles, Mobike bicycles, small white bicycles, and so on. The yellow and yellow oranges appeared in the streets of major cities. How do the locks of these bicycles work?
The smart lock of a shared bicycle is actually a combination of a Bluetooth smart lock and an Internet cloud server control, which is similar to a traditional Bluetooth door lock. The difference is that the number of server requests and commands is not at a hierarchical level.
The steps for unlocking a shared bicycle are as follows:
1. The user scans the code through the mobile phone APP. The two-dimensional body code is equivalent to the identity card of the bicycle, including the vehicle number, vehicle ID, requesting the unlocking action, and so on.
2. The mobile phone APP remotely sends a signal requesting unlocking to the cloud server, including vehicle information and numbering.
3, The server receives the request information, identifies the vehicle, sends an unlock command after confirmation, and sends the command with the specified number.
4. The bicycle receives the command and executes the server command to perform the corresponding unlocking action.
5. When the user starts the riding action by unlocking, the mobile phone starts to charge for a fee.
The above is the working principle of shared bicycle unlocking, let's look at the structure of shared bicycle smart locks.
Shared bicycle smart lock structure detailedLet's start with a picture to understand the basic structure and workflow of shared bicycle locks:
Through the above picture, we can know that in the mechanical structure, the shared bicycle smart lock consists of mobile phone APP and smart round lock / U-lock / horseshoe lock and other shapes of locks, essentially Bluetooth smart lock with a chip.
Its main structure is the chip, mobile phone APP, physical lock.
In general, the shared bicycle smart lock has a simple structure and is not much different from an ordinary bicycle lock in terms of appearance. The biggest difference lies in the chip identification control. Therefore, the role of the chip is mainly introduced herein.
Shared bike smart lock chip: ST17H30 QFN20pin BLE4.0 ultra-low-power chip.
The main function of the chip: support positioning, Bluetooth IC can directly drive the motor, support a variety of unlocking methods, can be unlocked through different ways such as two-dimensional code scanning mode/Bluetooth connection mode unlocking, support over-the-air upgrade OTA, with multiple encryption functions.
The chip plays the role of the central brain. The vehicle is numbered and positioned for encryption and anti-cracking. The server sends an unlock command that is equivalent to a Bluetooth shared key. After the chip is matched, it controls the car lock to open.
The above is a smart lock China Network Xiaobian finishing published on the sharing of bicycle smart lock working principle and structure (mainly the chip) knowledge introduction, more related content, please pay attention to the site column articles!
