detailed description

An embodiment of the present invention will be further described below in conjunction with the accompanying drawings.

In the embodiment of the present invention, as shown in Figure 1 and Figure 2, an intelligent fingerprint bicycle lock system includes a mobile terminal and a lock device provided with fingerprint unlocking, and the mobile terminal communicates with the lock device wirelessly connected, the car lock device includes a wireless switch lock part and an alarm part; the wireless switch lock part includes: a single-chip microcomputer, a steering gear, a lock cylinder piston, a bluetooth module and an LED light; the described alarm part includes a three-axis acceleration Electronic gyroscope and buzzer; the single-chip microcomputer, steering gear, bluetooth module, three-axis acceleration electronic gyroscope and buzzer are arranged inside the car lock body; the described LED lights are arranged on the surface of the car lock body, and the The lock cylinder piston is arranged on one side of the car lock body; the steering gear is engaged with the lock cylinder piston through gears.

In the embodiment of the present invention, the single-chip microcomputer adopts the MSP430G2553 model; the three-axis acceleration electronic gyroscope adopts the MPU6050 model; the mobile terminal is a mobile phone;

In the embodiment of the present invention, as shown in Figure 2, the single-chip microcomputer is connected to the mobile terminal through the Bluetooth module, the input end of the single-chip microcomputer is connected to the output end of the three-axis acceleration electronic gyroscope, and the first output end of the single-chip microcomputer is connected to the steering gear. The second output end of the single-chip microcomputer is connected with the LED lamp, and the third output end of the single-chip microcomputer is connected with the buzzer.

In the embodiment of the present invention, the method of using the intelligent fingerprint bicycle lock system to switch the lock, as shown in Figure 3, includes the following steps:

Step 1, enter the user fingerprint through the mobile terminal;

In the embodiment of the present invention, when in use, open the APP of the mobile phone, and the interface shown in Figure 4 will appear, click Settings to enter the fingerprint, and the LED light will be yellow during the entry process, and the LED light will be green when the mobile phone prompts that the entry is successful;
