Sharing car unlocking principle sharing car Bluetooth unlocking working principle
What is the shared car unlocking principle? What is the principle of sharing car phone Bluetooth unlock? The concept of the shared economy has been rapidly developed once it is launched. Shared bicycles are designed to solve the last-mile travel problem, but for problems with longer distances, the disadvantages of slow cycling and physical exertion are amplified. Sharing car-based travel modes based on electric vehicles is a better solution, but what is the principle behind unlocking the mobile phone APP?
The door lock of a shared car is in fact a lock based on a Bluetooth lock. Currently, there are many shared car brands on the market. Cities such as Guangzhou, Shenzhen and Shanghai have been launched.
Therefore, the way to unlock the shared car and the principle is based on the working process of the Bluetooth lock. The detailed steps are as follows:
1, mobile phone APP remote viewing near the reservation of vehicles, equipped with GPS positioning, you can view the nearby car.
2, need to be close to the shared car, in the Bluetooth connection range, open the cellular network and Bluetooth connection, select the corresponding number of cars.
3, open the APP smart unlock, transmit the door request information to the server.
4, the server receives the information, the correctness of the audit information, will send a drive door lock command after success.
5. The mobile phone receives the command and sends the command to the door lock chip through Bluetooth. At this time, the unlock command is equivalent to the Bluetooth key function, and the designated car can be opened.
6, the designated number of cars receive Bluetooth information, the chip performs matching processing, after confirmation will open the central control lock.
7, the user can manually open the door and enter the cab to use the car.
8. When the shared car starts, the mobile phone APP starts to charge according to the mileage, and calculates the distance according to the GPS positioning information.
9. When the car is finished to use, the car door lock will be automatically closed after the car is successfully returned. The central control lock is not openable.
The above is the workflow of sharing cars. Some brands may have nuances. The main difference is whether the door lock chip is equipped with a network module and whether it can be directly connected to the server. The main flow is basically the same.
I believe that after reading the smart lock China Network Xiaobian released the shared car unlocking principle, the owners of the car for the shared car workflow has a more clear concept, more car lock knowledge, please pay attention to the site related columns!
