[0044] The technical solution of the present invention is further described in detail below through the accompanying drawings and embodiments.

[0045] Figure 1 The flowchart of the control method of the anti-theft device provided by the embodiment of the present invention is as follows. Figure 1 In addition, the mobile terminal used in the embodiment of the present invention is a dedicated customized mobile terminal, or a mobile terminal loaded with a specific application that can access the paper supply device management server.

[0046] The unlocking control method of the anti-theft device provided in this embodiment includes the following steps:

[0047] Step 101, the mobile terminal scans the identification code on the paper supply device to obtain the identification code information;

[0048] Wherein, the identification code information includes a device ID;

[0049] Specifically, the mobile terminal is a smart phone or mobile tablet with image recognition and Internet access functions; the identification code is specifically a QR code or a barcode; the device ID specifically includes the device name, device number and operating status information, etc.

[0050] In a specific implementation process, a user uses a mobile terminal to scan a two-dimensional code image on a paper supply device, where the two-dimensional code image includes a device ID.

[0051] Of course, non-administrator users can also scan the QR code. When a user uses a non-customized mobile terminal (i.e. a mobile terminal without administrator privileges) to perform the above-mentioned QR code scanning operation, a security prompt interface will first appear, informing the user that his or her operating privileges will be subject to corresponding restrictions.

[0052] Step 102, the mobile terminal decodes the identification code information, generates and outputs a user interaction interface, receives anti-theft device unlocking instruction information input by the user in the user interaction interface, and sends the anti-theft device unlocking instruction information to the background server;

[0053] Specifically, the user interaction interface includes user options, device options, mobile terminal options, device operation status options and anti-theft device setting options, and each option is provided with a corresponding submenu or status information.

[0054] In a specific implementation process, the image recognition device in the mobile terminal recognizes the QR code scanned in step 101, generates and outputs a user interaction interface through analysis and is displayed on the mobile terminal. The user inputs unlocking instruction information for the anti-theft device option in the user interaction interface and performs related operations on other options through the touch screen of the mobile terminal, and then sends it to the background server through the mobile terminal, wherein the anti-theft device unlocking instruction information includes the user ID of the mobile terminal, the anti-theft device unlocking instruction, the device ID and the terminal ID of the mobile terminal; when the user uses a non-customized mobile terminal to perform the above operations, there is only one option for inputting the anti-theft device unlocking instruction information in the user interaction interface. This design can prevent user ID leakage and reduce the probability of misoperation.

[0055] The mobile terminal sends the anti-theft device unlocking instruction information to the background server through the 4G communication module or WIFI communication module in the mobile terminal.

[0056] Step 103, the backend server parses the anti-theft device unlocking instruction information, queries the paper supply device administrator data list according to the device ID, user ID and terminal ID, and determines whether the user is an administrator user in the paper supply device;

[0057] Specifically, the paper supply equipment administrator data list includes data of all authorized paper supply equipment administrators and data of authorized equipment maintenance personnel.

[0058] In a specific implementation process, the background server receives the instruction information sent by the mobile terminal, and can obtain the anti-theft device unlocking instruction information through analysis, and can also obtain the device ID, user ID and terminal ID information of the mobile terminal. By querying and comparing the device ID, user ID and terminal ID of the mobile terminal with the paper supply device administrator data list stored in the background server, it can be determined whether the current user ID is an authorized administrator of the paper supply device; when a non-administrator user uses the mobile terminal to perform the above operations, the background server receives the information sent by the mobile terminal and parses it, and obtains the anti-theft device unlocking instruction information, device ID and user ID information. By querying and comparing the device ID and user ID with the paper supply device administrator data list stored in the background server, it is determined that the current user is a non-administrator user, and step 109 is executed. The background server generates second feedback information and sends it to the mobile terminal to prompt that the user authority authentication has failed.

[0059] When it is determined that the user is an administrator user of the paper supply device, step 104 is executed.

[0060] Step 104, the backend server generates first control instruction information according to the anti-theft device unlocking instruction and the device ID, and sends it to the paper supply device;

[0061] Specifically, when the device ID, user ID and terminal ID of the mobile terminal are compared with the paper supply device administrator data list in the background server and the person is confirmed to be an authorized administrator of the paper supply device, the background server generates control instruction information corresponding to the device ID based on the anti-theft device unlocking instruction information and the device ID. The control instruction information corresponding to the device ID is sent by the background server to the paper supply device corresponding to the device ID, ensuring that the anti-theft device unlocking instruction information sent by the user from the mobile terminal matches the anti-theft device unlocking instruction information sent by the background server to the corresponding device ID.

[0062] The control instruction information is specifically anti-theft device unlocking instruction information.

[0063] In a specific implementation process, when the device ID, user ID and terminal ID of the mobile terminal are compared with the paper supply device administrator data list in the background server, and it is confirmed that the current user is an authorized administrator of the paper supply device, the background server generates a first control instruction information based on the received anti-theft device unlocking instruction information and device ID, and the first control instruction information is sent by the background server to the paper supply device of the corresponding device ID; for users who pass the above authentication using a non-customized mobile terminal, the background server also generates control instruction information corresponding to the device ID based on the anti-theft device unlocking instruction information and device ID, and the control instruction information is also sent by the background server to the paper supply device of the corresponding device ID.

[0064] After step 104, the control method further includes: the background server generates charging record information according to the device ID, the user ID and the terminal ID.

[0065] Specifically, the billing record information is the number of times the user ID applies for unlocking and the server responds and sends anti-theft device unlocking instructions within a billing cycle, which serves as the basis for the paper supply equipment supplier to settle the rental fee or consumables usage fee with the user.

[0066] In a specific implementation process, one week or one month is set as a billing cycle, and the background server records the number of times the user ID and terminal ID apply for unlocking instructions within the above billing cycle and the number of times the device ID accepts unlocking instructions within the above billing cycle and stores them in the background server, so that the supplier can settle relevant fees by retrieving the billing record information from the background server; for example, the user business to which the user belongs can be determined based on the user ID, and then the total number of times each user of the user business applies for unlocking instructions within the above billing cycle is counted, and the rental fee or consumables usage fee is calculated based on the single unlocking application fee or the total number of unlocking applications, and the billing record information is generated.

[0067] Step 105, the communication module of the paper supply device receives the first control instruction information and transmits it to the main control board of the paper supply device;

[0068] Specifically, the communication module of the paper supply device is a 4G communication module or a WIFI communication module, and the communication module and the main control board can be connected through a serial port.

[0069] In a specific implementation process, the background server sends the anti-theft device unlocking instruction information to the paper supply device. The paper supply device receives the information from the background server through the built-in 4G communication module or WIFI communication module, and transmits the received instruction information to the main control board.

[0070] Step 106, the main control board parses and processes the first control instruction information to obtain an anti-theft device unlocking instruction, generates an unlocking signal according to the anti-theft device unlocking instruction, and sends the unlocking signal to the electronic lock of the paper supply device through the adapter board of the paper supply device, so that the electronic lock performs an unlocking operation according to the unlocking signal;

[0071] Specifically, the main control board parses and processes the command information received from the communication module into a corresponding electrical signal, and sends the unlocking electrical signal to the electronic lock through the adapter board; the adapter board is used for signal transmission and power supply between the electronic lock and the main control board. A serial port is provided on the surface of the adapter board. The main control board and the electronic lock are connected to the serial port through a control line. The electronic lock performs an unlocking operation according to the received unlocking signal.

[0072] In a specific implementation process, the main control board receives the unlocking command information transmitted from the communication module, and converts it into a corresponding unlocking electrical signal through analysis and processing. The main control board is connected to the adapter board through a control line, and the adapter board is also electrically connected to the electronic lock through the control line, so that the unlocking electrical signal is sent to the electronic lock through the adapter board, and the electronic lock executes the unlocking operation after receiving the unlocking electrical signal; the specific structure of the electronic lock and the unlocking execution process will be described accordingly in the embodiments of the subsequent device.

[0073] Step 107, the main control board receives the unlocking status feedback information of the electronic lock, generates first feedback information according to the unlocking status feedback information, and sends it to the background server through the communication module;

[0074] Specifically, the first feedback information includes the device ID and unlocking completion status information;

[0075] Step 108: The backend server sends the first feedback information to the mobile terminal to prompt the user that the unlocking is completed.

[0076] Specifically, in order to confirm whether the unlocking instruction input by the mobile terminal is received and executed by the electronic lock, the background server will simultaneously feedback the unlocking status to the user. Through the first feedback information, the user can effectively avoid disassembling the upper front shell of the paper feeding device without executing the unlocking of the electronic lock, which may cause damage to the device shell.

[0077] In a specific implementation process, after the electronic lock completes the unlocking operation, it will automatically generate status information and send it to the main control board through the adapter board. The status information received by the main control board includes the device ID, terminal ID and unlocking status feedback information. The main control board processes and generates first feedback information based on the device ID, terminal ID and unlocking status feedback information. The main control board sends the first feedback information to the background server through the communication module. The background server sends the received first feedback information to the mobile terminal corresponding to the terminal ID, prompting the user of the mobile terminal that the unlocking is completed. For users using non-customized mobile terminals, the above feedback information cannot be obtained.

[0078] After the aforementioned step 103, when it is determined that the user is not an administrator user of the paper supply device, step 109 is executed:

[0079] Step 109: the backend server generates second feedback information and sends it to the mobile terminal to prompt the user that the authority authentication fails.

[0080] Specifically, when the device ID, user ID and terminal ID information of the mobile terminal obtained by the background server cannot be found in the paper supply device administrator data list, the background server will generate a second feedback message and send the user authority authentication failure information to the corresponding mobile terminal. In addition, the background server can also output advertising information of the paper supply device to the mobile terminal.

[0081] To close the electronic lock, follow these steps:

[0082] Step 201, the electronic lock generates closing state feedback information according to the closing operation, generates third feedback information according to the closing state feedback information, and sends it to the background server through the communication module;

[0083] Specifically, the third feedback information includes device ID and locking completion status information;

[0084] In a specific implementation process, in order to inform the mobile terminal that the electronic lock has completed locking, the background server will feedback the locking status to the user. The electronic lock automatically generates closing status feedback information based on the closing operation and sends it to the main control board through the adapter board. The status information received by the main control board includes the device ID, terminal ID and locking status feedback information. The main control board generates third feedback information based on the device ID and the locking completion status information, and sends the third feedback information to the background server through the communication module.

[0085] Step 202: The backend server sends third feedback information to the mobile terminal to prompt the user that the locking is completed.

[0086] Specifically, the user opens the upper front shell of the paper supply device according to the first feedback information, and after completing the replacement of toilet paper and other related tasks, restores the upper front shell of the paper supply device to its original position. The main control board generates third feedback information according to the closing state information. The third feedback information includes the device ID and the locking completion state information. Through the third feedback information, the user can confirm whether the internal electronic lock and the lock buckle are fastened, thereby avoiding the occurrence of toilet paper theft or equipment damage due to the failure of the internal electronic lock and the lock buckle of the paper supply device to fasten.

[0087] In a specific implementation process, the background server sends the received third feedback information to the mobile terminal corresponding to the terminal ID, prompting the user of the mobile terminal that the electronic lock is locked.

[0088] The control method of the anti-theft device provided by the embodiment of the present invention solves the problem that the existing mechanical paper feeding equipment cannot realize non-contact intelligent unlocking and does not need to use medium to unlock, which can prevent theft and facilitate unlocking.

[0104] The Bluetooth module 7 is arranged in the main control board 3, and is used for enabling the anti-theft device to interact with the mobile terminal and realize the unlocking operation when the anti-theft device cannot interact with the background server and realize the unlocking operation.

[0105] The unlocking process of the electronic lock is described in detail below through a specific implementation process.

[0106] The user uses a smart phone or mobile tablet with image recognition and Internet access functions to scan the two-dimensional code image or barcode located on the front shell 11 of the device shell 1, and the image recognition device in the smart phone or mobile tablet recognizes and analyzes the image or barcode to generate a user interaction interface and outputs it for display on the mobile terminal. The mobile terminal receives the user's input operation of unlocking the anti-theft device option in the user interaction interface through the touch screen, and then sends it to the background server through the communication module in the mobile terminal. The background server receives the instruction information sent by the mobile terminal, and can obtain the anti-theft device unlocking instruction information and the device ID, user ID and terminal ID information of the mobile terminal through analysis. The device ID, user ID and terminal ID of the mobile terminal are compared with the paper supply device administrator data list stored in the background server to determine whether the current user ID is an authorized administrator of the paper supply device; when it is confirmed that the current user ID is an authorized administrator of the paper supply device, the background server can obtain the unlocking instruction information of the anti-theft device and the device ID, user ID and terminal ID of the mobile terminal. After the paper equipment is authorized by the administrator, the background server generates the first control instruction information according to the received anti-theft device unlocking instruction information and the device ID, and the first control instruction information is sent by the background server to the paper supply device of the corresponding device ID; wherein, the first control instruction information is specifically the anti-theft device unlocking instruction information; while the background server sends the first control instruction information to the paper supply device, the background server generates the billing record information according to the device ID, the user ID and the terminal ID; the paper supply device receives the anti-theft device unlocking instruction information from the background server through the built-in communication module 2, and the communication module 2 transmits the received instruction information to the main control board 3; the main control board 3 receives the unlocking instruction information transmitted from the communication module 2, and converts it into a corresponding unlocking electrical signal through analysis and processing, and sends the unlocking electrical signal to the adapter board 4; the unlocking electrical signal is sent to the electronic lock 5 through the adapter board 4, and the electronic lock 5 performs the unlocking operation after receiving the unlocking electrical signal. Specifically, after the electronic lock 5 receives the unlocking electrical signal, the power supply 6 supplies power to the electronic lock 5 through the adapter board 4 and the control line 56, and the motor inside the electronic lock 5 drives the lock tongue 54 to rotate counterclockwise in the lock tongue groove 53. As the lock tongue 54 slowly rotates, the buckle body 552 of the lock buckle 55 is disengaged from the groove 543 under the push of the lock tongue baffle 541. During this period, the lock tongue hook 542 is completely separated from the buckle body 552, and the buckle body 552 moves to the outside of the lock body 51 through the lock port 52 until the buckle body 552 is partially pulled out of the lock body 51, and the lock buckle 55 is separated from the lock body 51 and unlocking is achieved.
