Anti-theft unlocking scheme for two-wheeled vehicle bluetooth alarm

1. Program overview:

Electric bicycles have received strong support from the government for their economy, ease of use, energy saving, emission reduction and noise reduction, and have become the best choice for working-class household second-wheel mobility tools. However, as electric bicycles have entered thousands of households, their theft rate has also risen year by year, bringing considerable economic losses to users. Although the existing wireless anti-theft device solutions have solved the anti-theft problem of electric bicycles, the solution Too bloated and cumbersome, you need to carry a key and remote control to unlock, which is more inconvenient to travel.



In order to further improve the convenience of travel, Shengrun Technology combined its previous experience in the electric vehicle alarm industry to design a new anti-theft unlocking solution that is different from the traditional electric vehicle unlocking solutions on the market. The solution is designed based on Bluetooth low energy technology. Under the premise that the cost increase is not obvious, the convenience of the Bluetooth interaction of the smart phone is used to replace the key and the remote control to "lighten the burden" for travel.

2. Program features:

There is a Bluetooth slave module inside, which is connected by the mobile phone to do two-way identity verification with the mobile phone

Provide BLE signal strength to the mobile phone for calculation and positioning

Authorize to the controller to control the state of the vehicle

Anti-theft alarm prompt

Vehicle information interaction

Communication encryption



3. Program advantages:

Bluetooth high frequency encryption---Bluetooth 2.4G high frequency encryption communication mechanism to make the product more secure.

Software algorithm encryption-through software algorithm encryption, making the product more robust.

Application-side authority management --- Through the application-side authority management, the product is safer and more user-friendly.
