The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiment of the present invention, all other embodiments obtained by the person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, fig. 2 and fig. 3, the present embodiment provides an RFID-based intelligent warehousing system, including a cabinet 10, an RFID tag and an RFID read-write device 20, where the RFID tag is used to record related information of an object, and the RFID read-write device 20 is used to read information in the RFID tag; a lock and a lock control unit 30 for controlling the lock to open or close are arranged on a cabinet door of the cabinet body 10, and the lock control unit 30 comprises a memory, a control circuit 303, and a fingerprint identification module 301 and an identity card identification module 302 which are respectively connected with the control circuit.

The cabinet 10 includes a plurality of cabinets 101 and doors, and the cabinets 101 are used for placing objects. In one embodiment, the volume of each of the pockets is the same, but in a more preferred embodiment, at least two of the plurality of pockets have different volumes to facilitate placement of different sized articles.

As shown in fig. 2, the control circuit 303 includes a microcontroller, an and gate, and a driving circuit, the fingerprint identification module 301 and the identification card identification module 302 are both connected to the microcontroller, two output terminals (I/O ports) of the microcontroller are connected to two input terminals of the and gate, and an output terminal of the and gate is connected to the driving circuit. After the fingerprint identification module and the identity card identification module are successfully identified, the microcontroller outputs two high level signals, the AND gate outputs the high level signal at the moment, then the drive circuit is triggered to work, and the lock is driven to be opened.

During the specific use, fingerprint identification module record administrator's fingerprint, when borrower A will borrow a certain article, this moment, need the administrator to input its fingerprint password, borrower A need provide its ID card, and it is correct when fingerprint identification module discerns the fingerprint, and behind ID card identification module discernment borrower A's ID card information, drive circuit drive tool to lock is opened.

In order to have more information to trace, optionally, a camera can be arranged outside the cabinet door, and the camera is connected with the microcontroller and used for collecting video or pictures on site and storing the collected video or pictures in the memory.

The fingerprint identification module and the identity card identification module can adopt any chip in the prior art, and can realize fingerprint identification and identity card information identification. The lock structure and the driving circuit thereof can also adopt the structure in the prior art, and the scheme of the embodiment is not improved.

In one mode, the number of the RFID reading-writing devices can be multiple, and one RFID reading-writing device is installed at each cabinet slot. However, in another preferred mode, one RFID read-write device is provided on the cabinet door, and when an object is to be taken out or put in, the RFID tag is moved (manually taken) to the RFID read-write device to read information, so that the cost of the RFID read-write device is reduced while the object information is read.

In one mode, the number of the RFID tags can be multiple, and one RFID tag is arranged on one article. However, in another mode, the RFID tag may not be disposed on each object, but each cabinet slot corresponds to one RFID tag, and at this time, the cabinet door is further provided with a control panel, and the control panel is disposed with an up-flipping key, a down-flipping key, a confirmation key, and a display screen, which are all connected to the microcontroller. The control panel may correspond to the lock control unit location on the cabinet door, e.g. the control panel is located outside the cabinet door and the lock control unit is located inside the cabinet door.

For example, 5 items are placed in a certain slot, each item corresponds to one piece of information, and the RFID tag stores the information corresponding to the 5 items, respectively, for a total of 5 items. When the RFID reading and writing equipment reads the information in the RFID label, 5 pieces of information can be read out completely and displayed on the display screen, then the information corresponding to the object to be taken out is selected through the upturning key and the downturning key, and then the confirmation is carried out by pressing the confirmation key, so that the information record of the object to be taken out can be realized. The cost of the RFID tag can be greatly reduced by sharing one RFID tag by all articles in the same cabinet slot.

In the above scheme, only the recording of the object information can be realized through the RFID read-write device, but the recording of lending or returning of the object cannot be realized, and therefore, manual recording is also required or no recording is performed. Therefore, as a more optimized scheme, the cabinet door is further provided with two photoelectric sensors, the positions of the two photoelectric sensors are staggered, and the two photoelectric sensors are connected with the microcontroller. The purpose of the staggered arrangement of the two photoelectric sensors is to enable the two photoelectric sensors to detect the objects at different times, and the record of borrowing or returning of the objects is realized through the sequence of the detected objects. For example, the photoelectric sensor of the number a detects the object first, and the photoelectric sensor of the number B detects the object later, which indicates that the object is taken out of the cabinet body from the cabinet body, i.e., borrowed, whereas, for example, the photoelectric sensor of the number B detects the object first, and the photoelectric sensor of the number a detects the object later, which indicates that the object is put into the cabinet body from the outside of the cabinet body, i.e., returned.

Alternatively, for some expensive objects, a positioning chip, such as GM4622, OTrack-128, etc., may be embedded on the object. The positioning chip is convenient for positioning and tracking the object.

Optionally, a smoke detector and an alarm can be arranged on the cabinet door, and both the smoke detector and the alarm are connected with the microcontroller. The smoke detector can timely find smoke, the alarm is triggered to send out an alarm signal when the smoke detector finds the smoke, a fire hazard is avoided, and articles in the cabinet body are reliably protected.

The microcontroller can also be connected with a communication module, for example, communication between the microcontroller and a designated terminal is realized, so that related personnel can be timely notified when an emergency occurs, and timely processing can be carried out.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
