Examples

The technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

As shown in FIG. 1, the Bluetooth dynamic password storage box system is composed of a dynamic password storage box, a server, and a smart client device. The storage box has a storage space, a unique device identifier, a Bluetooth module, and a combination lock component. The storage space is used to store small items, and the storage box has a unique device identifier. The unique device identifier corresponds to the unique storage box device number; the Bluetooth module can be wirelessly connected to the smart client device; the password lock component includes a processor, clock IC, storage medium, password input keyboard, unlock drive circuit, lock tongue, and battery, The processor generates a dynamic password based on the device number of the storage box and the encryption operation of the clock IC.

The smart client device can obtain the device number of the storage box through Bluetooth communication, and send the device number to the server. The server determines whether the storage box has authority at the current time according to the requested account, if Have the authority to generate a dynamic password based on the device number and server clock encryption operation, and send the dynamic password to the client device, the client device sends the dynamic password to the storage box via Bluetooth communication, the After the storage box is matched with the password, the unlocking drive circuit is controlled to open the lock tongue, and the storage box is opened. The processor of the server and the storage box calculates the dynamic password according to the same device number, time and calculation rule, so the two dynamic passwords are consistent.

As shown in FIG. 2, the dynamic password storage box further includes a display screen, which is provided outside the box body, specifically, the OLED12864 display screen displays input and system feedback information, which is a better human-computer interaction experience for users.

The processor is specifically the STM32L151C8T6 processor. It also has a power management chip and a motor drive chip. The power management chip can effectively prevent the battery from being over-discharged and overcharged, and at the same time ensure that the electronic circuit is working safely and effectively. The motor drives the chip to drive the motor. The processor controls the drive chip to output different currents to control the motor to do different rotations. The motor can use a 3V clutch motor. The power management chip can use the TP4056 power management chip, and the motor drive chip can use the DW01+G motor control chip.

The battery is a rechargeable battery, such as a lithium battery, and the processor includes a power chip and a motor drive chip, and the battery supplies power to the power chip and the motor drive chip, respectively.

The clock IC can be a DS1307 clock chip, which provides accurate clock information and is used to calculate the unlock password.

Door lock switch detection mechanism to obtain door lock status in real time. It is convenient for better management of door lock status information. Specifically, the Hall sensor and micro switch can be installed near the lock tongue to determine the extended or retracted state of the lock tongue, so as to perform corresponding operations, such as displaying the lock status on the lock body through the processor. on.
