Detailed Description

The utility model provides an intelligent key box, key box including the metal material, all install RFID label (chip) on the drop of every key of this key box, install central control module in this key box, this central control module includes microcontroller MCU, this microcontroller is connected with power module, bluetooth unlocking module, hyperfrequency RFID read write line, electronic lock and network connection module respectively, this network connection module is connected with backstage server through wired or wireless network, still include the mobile terminal that has the bluetooth function, this mobile terminal is connected with backstage server through wireless network;

or the hang tag of each key is provided with a two-dimensional code, and the keys are not placed in the key box in sequence.

In addition, a camera module is installed on the outer side surface of the intelligent key box and can be used for assisting in identifying an applicant, the camera module is connected with the microcontroller, the mobile terminal adopts an intelligent mobile phone, the microcontroller is also connected with the Bluetooth unlocking module, and the electronic lock can be unlocked through the Bluetooth function of the intelligent mobile phone (see Chinese patent 201810645694.2, namely an unlocking system and method based on the WeChat applet and Bluetooth), and certainly, the electronic lock can also be directly unlocked through the microcontroller by a background server.

The utility model discloses a use method and theory of operation are:

the key box door is made of metal materials, can shield signals of an RFID chip outside the box, is provided with a two-dimensional code of a WeChat applet, opens the unpacking applet through WeChat code scanning, interacts with a back-end server through an applet applicant, sends a key borrowing application to the server when the key is borrowed, the application comprises identity information of an applicant, a key number or a name to be borrowed, and preferably, a camera can be added to the key box or the camera of a handheld terminal of the applicant, so that an image of the applicant is transmitted to the back-end server. The back-end server sends the application of the applicant for borrowing the key and can also comprise the image of the applicant to a manager for verification and authorization, after the authorization of the manager is obtained, the back-end server controls the Bluetooth on the mobile phone of the applicant through a small program, the Bluetooth of the mobile phone is communicated with a central control device in the intelligent key box through the mobile phone Bluetooth, and the cabinet door is opened. Referring to the patent, application No. 201810645694.2 "an unlocking system and method based on WeChat applet and Bluetooth", but the method cannot confirm and manage the article taken out of the locked space after unlocking)

The ultrahigh frequency RFID reader-writer is arranged in the box, data of a plurality of RFID chips can be read simultaneously, the RFID chip is contained in the hangtag of the key, the name of the key representing the key is printed on the front face of the hangtag of the key, two-dimensional codes can be printed simultaneously, and the two-dimensional codes can play a role in a system and a method for confirming object transfer by scanning codes by using a mobile terminal or returning the key (the two-dimensional codes can contain the serial number of the RFID chip and the name of the key) when the key is handed over

The RFID card reader in the key box can scan and read the RFID chip contained in the key tag in the box once at regular time or when the box opening application is received or after the box is opened, or the combination of the schemes, and upload the RFID chip information to the server, and the server stores the corresponding relation between the RFID chip information and the key name. By adopting the scheme, the final purpose is to ensure that the server can know which keys are in the box before the box is opened, and the server can know that the key borrower takes away the keys and whether the keys are consistent with the keys to be borrowed after the box is opened.

Specifically, there are two key-taking schemes:

scheme 1: fixed position of key suspension (two-dimensional code printed on the tag, digital number printed)

The method comprises the steps that slot numbers for hanging keys are printed on the back of a key drop, each key corresponds to a slot for hanging the key, a server sends a key list in a box to an applicant through a WeChat applet, the list comprises key names and numbers, the lent keys can not be displayed or remarked and are borrowed, the numbers are the same as the slot numbers, the applicant sends the slot numbers for selecting the keys to the server through the applet, the server sends RFID chip information of the keys needing to be taken out of the box to a controller in the key box, the key box controller detects the change of the RFID information read in the box, the correct keys are checked and judged, meanwhile, the RFID information of the keys lacking in the box or the RFID information of the rest keys is uploaded to the server, meanwhile, the key information on the server is updated, and the information of an applicant and the borrowed keys is recorded.

Scheme 2: the key box is hung conveniently, the sequence is not fixed (two-dimension code printed on the hang tag)

The server sends an in-box key list to the applicant through a WeChat applet, wherein the list comprises key names, the lent key can not be displayed or remarks are lent, the applicant scans two-position code information on a key hanging tag through a two-dimension code scanning tool in the applet to determine a key to be taken away, the applet sends the two-dimension code information scanned by the applicant to a back-end server, the back-end server sends RFID chip information in a two-dimension code on the key hanging tag to a controller in the key box, the controller of the key box judges whether the taken-out key is correct by comparing detected changes of an in-box RFID chip, meanwhile, RFID information of keys lacking in the box or RFID information of the rest keys is uploaded to the back-end server, meanwhile, key information on the back-end server is updated, and information of an applicant and the borrowed key is recorded. The optional slot position can be designed into a shape that the slot position and the key tag are matched with the protrusion and the recess, so that the condition that the two-dimensional code surface on the tag can only face outwards when the key is hung is limited.

When the key is returned, the process of opening the key box is similar to that of borrowing the key, the small box opening program is opened through the WeChat code scanning, the small program applicant interacts with the back-end server, the returned key application is sent to the server, the application comprises the identity information of the applicant, the number of the key to be returned or the two-dimensional code on the key is scanned again through the small program, and preferably, a camera can be added to the key box or the camera of the handheld terminal of the applicant is used for transmitting the image of the applicant to the back-end server. The back-end server sends the return application of the applicant, and the image of the applicant can also be included to a manager for verification and authorization, after the authority of the manager is obtained, the back-end server controls the Bluetooth on the mobile phone of the applicant through a small program, the mobile phone Bluetooth is communicated with a central control device in the intelligent key box to control the door lock to open the cabinet door, then the key is put back to the key box, an RFID card reader of the key box reads the RFID information of all keys and compares the RFID information with the RFID information of all keys stored before the cabinet door is opened, meanwhile, the RFID information of all keys is uploaded to the server, the central control or the back-end server of the key box judges that the key is returned, finally, the key information on the back-end server is updated, and the information of the applicant and the returned key is recorded.
