Contents of the invention

The utility model provides a locker system based on fingerprint identification technology aiming at the deficiency of the prior art.

The utility model comprises a main controller, an RS485 bus interface and a plurality of locker groups, and the main controller is connected with the RS485 interface of each locker group through the RS485 bus interface.

The locker group includes an LCD display module, an RS485 interface, an MCU module, a plurality of electromagnetic locks, a fingerprint collection module and a voice chip. Each electromagnetic lock is respectively installed on a plurality of small cabinets of the cabinet group.

The I/O interface of the MCU module in the locker group is connected with the LCD display module, RS485 interface, electromagnetic lock, fingerprint collection module and voice chip. The locker system supplies power to the main controller and the MCU modules, LCD display modules, fingerprint collection modules, and voice chips of each cabinet group through an external power supply.

Both the main controller and the MCU module are composed of AVR single-chip microcomputers.

Multiple locker groups are connected to the main controller through the RS485 bus for network use; a single locker group can also be used independently.

The beneficial effect that the utility model has:

(1) The utility model not only applies the fingerprint identification technology to the locker system, but also makes the existing locker system more operable, easy to operate, and improved in safety. In addition, the utility model also utilizes the AVR single-chip microcomputer to process data, which greatly reduces the use cost.

(2) The utility model has a convenient and intelligent storage function. For users, they only need to input fingerprint information when depositing objects, and the locker system will allocate free cabinets to users and record the fingerprint information of the users of the cabinets. When users take objects, the locker system will It will identify the cabinet number and cabinet number corresponding to the user's fingerprint. After the retrieval is completed, the system will clear the fingerprint information corresponding to the cabinet for redistribution.

(3) The utility model has powerful and flexible networking and expansion functions. This locker system can be used in a single cabinet group, or multiple cabinet groups can be used in a network, and the cabinet groups are connected to the main controller through the RS485 bus. The main controller records and queries the information of each cabinet group, including information such as whether there are free cabinets in the cabinet group and cabinet switch records. The utility model can also expand and control any number of locker groups according to the different needs of customers.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, a kind of locker system based on fingerprint identification technology of the present utility model comprises main controller, RS485 bus interface and a plurality of locker groups, and main controller communicates with each locker through RS485 bus interface Set of RS485 interface connections.

The locker group adopted includes LCD display module, RS485 interface, MCU module, multiple electromagnetic locks, fingerprint collection module and voice chip. Each electromagnetic lock is respectively installed on multiple small cabinets of the cabinet group; the I/O interface of the MCU module in the locker group is connected with the LCD display module, RS485 interface, electromagnetic lock, fingerprint collection module and voice chip. Among them, the LCD display module and voice chip are used as output signals, the fingerprint collection module is used as input signals, and the RS485 interface and electromagnetic lock are used as input and output bidirectional signals; the locker system supplies the main controller and the MCU modules of each cabinet group, LCD Display module, fingerprint acquisition module, voice chip power supply.

The main controller used and the MCU module of a single locker group are all composed of AVR single-chip microcomputers.

In the utility model, a plurality of locker groups are connected to the main controller through the RS485 bus for network use; a single locker group can also be used alone.

As shown in Figure 2, the control method of the control flow of a single locker group is as follows:

(1) After the fingerprint information collected by the fingerprint acquisition module is processed, the information is sent to the MCU module;

(2) The MCU module judges whether the input fingerprint information has been stored;

(3) If there is no such fingerprint information, the MCU module will allocate an idle small cabinet, and open the corresponding electromagnetic lock of the cabinet door through the drive circuit, and store the fingerprint information and the associated information of the cabinet in the MCU module at the same time; when the cabinet door is opened, the LCD Display the number of the cabinet door to open, and the voice chip will issue a voice prompt;

(4) If the fingerprint information is stored, the MCU module will control the drive circuit to open the previously allocated cabinet door electromagnetic lock; when the cabinet door is closed again, the closing signal of the electromagnetic lock will be sent to the MCU module, and the MCU module will Fingerprint information is deleted from memory.

As shown in Figure 3, the control method for the networking of multiple lockers is as follows:

(1) The fingerprint collection module of any cabinet group processes the collected fingerprint information and sends it to the main controller through the RS485 bus;

(2) Determine whether the input fingerprint information has been stored in the main controller;

(3) If the fingerprint information exists in the main controller, then judge whether it is the locker group where the fingerprint is currently input. If it is, control the drive circuit of the cabinet group through the RS485 bus to open the previously allocated cabinet door electromagnetic lock; if it is not the locker group with the fingerprint information currently input, the LCD display and the voice chip will prompt the correct locker Group number; when the pick-up is finished, close the cabinet door and send the closing signal of the electromagnetic lock to the main controller to delete the fingerprint information;

(4) If the fingerprint information is not stored in the main controller; the main controller allocates the cabinets of the idle locker group, and opens the corresponding electromagnetic lock of the cabinet door through the drive circuit, and at the same time transfers the fingerprint information and the cabinet group and cabinet The associated information is stored in the main controller; when the cabinet door is opened, the LCD display and the voice chip prompt which cabinet number of the cabinet group is opened.
