[0053] Current Internet of Things cards are widely used in intelligent scenarios such as cars and smart wearables. The Internet of Things card is integrated into these devices at the factory, and it is not easy to take out. When the pre-recharge amount of the Internet of Things card is used up, the user needs to recharge the Internet of Things card integrated into the device. When the user needs to recharge, most of the time, the user needs to know the Internet of Things card number and go to a third-party Internet of Things card recharge platform to recharge. These numbers are provided to the user by the seller or manufacturer when the user purchases the device. Once the user forgets the Internet of Things card number, it is difficult to complete the recharge operation, which will cause inconvenience in use.

[0054] Therefore, the present application provides a method, system, device and medium for recharging an Internet of Things card. The method includes obtaining traffic data of the Internet of Things card, determining that the remaining amount of the Internet of Things card is lower than a preset threshold based on the traffic data, sending a recharge instruction including a recharge link, obtaining Internet of Things card information of the Internet of Things card through the recharge link, generating a custom recharge interface through the Internet of Things card information, and performing a recharge operation through the custom recharge interface. This method can read the Internet of Things card information in the terminal device and parse the Internet of Things card number, thereby eliminating the need for the user to input the Internet of Things card number during the recharge operation and avoiding the situation where the user forgets the Internet of Things card number and cannot recharge.

[0055] Reference Figure 1 , Figure 1 In an embodiment of the present application, an Internet of Things card recharge platform is provided, which includes a data acquisition module 101, a control center 102, a network center 103, and a database 104. The data acquisition module 101 is configured to acquire Internet of Things card data sent by a terminal and send the Internet of Things card data to the control center 102 for processing. The control center 102 is configured to execute a method for recharging an Internet of Things card, determine the cost of the Internet of Things card on the terminal by calling data in the data acquisition module 101 and the database 104, and control the network center 103 to send a recharge instruction containing a recharge link to the terminal. The network center 103 is configured to send a message reminding the user to recharge and a recharge instruction to the terminal device. The database 104 stores cost information of the Internet of Things card, so as to be called and updated by the control center 103.

[0056] It should be noted that only a part of the modules of the Internet of Things card recharge platform is exemplarily given in the embodiment of the present application, and the Internet of Things card recharge platform can further include other modules included in other existing Internet of Things card recharge platforms to realize corresponding functions, and the specific implementation is not limited.

[0057] Referring to Figure 2 , Figure 2 is a schematic diagram of a hardware structure of an Internet of Things card recharge platform to which embodiments of the present application relate. In the embodiments of the present application, the Internet of Things card recharge platform can include a processor 201 (for example, a central processing unit, CPU), a communication bus 202, an input port 203, an output port 204, and a memory 205. The communication bus 202 is used to realize the connection and communication between the components; the input port 203 is used for data input; the output port 204 is used for data output, and the memory 205 can be a high-speed RAM memory or a stable memory (non-volatile memory) such as a disk memory. The memory 205 can optionally also be a storage device independent of the aforementioned processor 201. Those skilled in the art can understand that the hardware structure shown in Figure 2 does not constitute a limitation on the present application, and can include more or fewer components than shown in the diagram, or combine certain components, or different component arrangements.

[0058] Continuing to refer to Figure 2 , Figure 2 , the memory 205 as a readable storage medium in Figure 2 may include an operating system, a network communication module, an application program module, and a control program. In Figure 2 , the network communication module is mainly used to connect to a server and communicate data with the server; and the processor 201 can invoke the control program of the Internet of Things card recharge platform stored in the memory 205 and execute the data exchange method provided by the embodiments of the present application.

[0059] Based on the Internet of Things card recharge platform shown in Figure 1 and Figure 2 , as shown in Figure 3 , the embodiments of the present application provide a method for recharging an Internet of Things card, including but not limited to steps S301, S302, S303, S304, and S305:

[0060] S301, obtaining flow data of an Internet of Things card.

[0061] In some embodiments, step S301 can be further divided into the following steps:

[0062] receiving an Internet of Things card data packet sent by an Internet of Things card information module on a terminal;

[0063] analyzing the Internet of Things card data packet, obtaining flow data of the Internet of Things card, and verifying the authority.

[0064] It should be noted that the Internet of Things card information module sends the Internet of Things card data package carrying mdn (Internet of Things card number), IMEI (device serial number) and MAC (local area network address) and other information related to the terminal device. Through these information related to the terminal device, the related permissions of the Internet of Things card and the user can be checked, for example: the use state of the Internet of Things card, the type of the Internet of Things card and the operation permission state of the user to which the Internet of Things card belongs. Specifically, in the process of using the Internet of Things card, the terminal device carrying the Internet of Things card will continuously send the Internet of Things card data package carrying the terminal device information to the data acquisition module 101 through the CHF message. Then, the data acquisition module 101 analyzes the Internet of Things card data package to obtain the terminal device information such as mdn (Internet of Things card number), IMEI (device serial number) and MAC (local area network address) and the traffic data of the Internet of Things card. Subsequently, the data acquisition module 101 sends the above device information to the control center 102. The control center 102 checks the permissions related to the Internet of Things card according to the above device information, such as the use state of the Internet of Things card, the type of the Internet of Things card and the operation permission state of the user to which the Internet of Things card belongs.

[0065] S302, according to the traffic data, determine that the remaining balance of the Internet of Things card is lower than the preset threshold, send the recharge instruction, the recharge instruction includes the recharge link.

[0066] According to the foregoing description, the traffic data of the Internet of Things card has been obtained through step S301. In step S302, it is necessary to determine whether the remaining balance of the Internet of Things card is lower than the preset threshold according to the obtained traffic data. If yes, the recharge instruction containing the recharge link is sent to the terminal device. If no, the obtained traffic data is sent to the database 104 and saved. Specifically, after the control center 102 receives the traffic data of the Internet of Things card, it determines whether the remaining balance of the Internet of Things card is lower than the preset threshold. When the remaining balance of the Internet of Things card is lower than the preset threshold, the control center 102 controls the network center 103 to send the recharge instruction with the recharge link to the terminal device for the user to perform the recharge operation. When the remaining balance of the Internet of Things card is not lower than the preset threshold, the control center 102 sends the obtained traffic data to the database 104 for saving. Wherein, the person skilled in the art can set the preset threshold according to the actual situation, which is not limited here.

[0067] Optionally, after determining that the remaining balance of the Internet of Things card is lower than the preset threshold, the following steps are further included:

[0068] Save the traffic data.

[0069] In this embodiment, by saving the traffic data, the traceability of the data is ensured, and when an error occurs in data transmission, the data saved in the database 104 can be called to repair.

[0070] S303, obtaining the Internet of Things card information of the Internet of Things card through the recharge link.

[0071] It should be noted that the Internet of Things card information includes the Internet of Things card number. The sent recharge link accesses the built-in Internet of Things card information module of the device to read the Internet of Things card information therein, so that the Internet of Things card information is called in subsequent steps.

[0072] S304, generating a custom recharge interface through the Internet of Things card information.

[0073] In step S304, a custom recharge interface needs to be generated according to the Internet of Things card information. It should be noted that the Internet of Things card information includes the Internet of Things card number, and the custom recharge interface will change accordingly according to the difference of the Internet of Things card number, for example: when the obtained Internet of Things card number is 11234567890, the custom recharge interface will display the Internet of Things card number "11234567890" at the "recharge account" position. It can be understood that the custom recharge interface can also change the recharge interface according to other Internet of Things card information, such as: obtaining the name "ABC" of the user, and displaying "Hello, respected ABC" in the custom recharge interface; or, obtaining the remaining balance of the Internet of Things card, and displaying the remaining balance in the recharge interface, so that the user can further understand the recharge information. In this embodiment, the Internet of Things card number is automatically parsed and obtained, and the recharge process without user awareness of the Internet of Things card number is realized.

[0074] S305, performing a recharge operation through the custom recharge interface.

[0075] According to the foregoing description, in step S304, a custom recharge interface containing the Internet of Things card number is generated, and the user only needs to perform a recharge operation according to his actual needs. Specifically, the user can perform an interactive operation (such as clicking, touching, gesture, input box input, drop-down menu selection, etc.) on the display interface to trigger a corresponding operation instruction to the recharge interface, and the recharge interface confirms the recharge operation after receiving the operation instruction, and then returns the recharge result to the recharge interface. In this embodiment, the recharge is performed through the custom recharge interface, which greatly solves the situation that the user forgets the Internet of Things card number and cannot recharge.

[0076] In some embodiments, after step S305, performing a recharge operation through the custom recharge interface, further comprising:

[0077] determining that the custom recharge interface completes the recharge operation, generating recharge information;

[0078] modifying the tariff information of the Internet of Things card according to the recharge information;

[0079] saving the tariff information.

[0080] Optionally, after the generating of the recharge information, the method further comprises the following steps:

[0081] encrypting the recharge information.

[0082] It should be noted that the Internet of Things card information in this step includes the Internet of Things card recharge amount and the Internet of Things card number, etc. The custom recharge interface verifies the Internet of Things card information obtained above, thereby determining that the recharge operation is completed, and generating recharge information. The recharge information includes the Internet of Things card number and the recharge amount, etc. In order to ensure the security of the user information, the recharge information needs to be encrypted at the same time of generating the recharge information. The encryption method can use MD5, MD4, etc. algorithm. The specific encryption algorithm can be selected by the person skilled in the art according to the actual situation, which is not limited here.

[0083] Optionally, the step of modifying the tariff information of the Internet of Things card according to the recharge information specifically comprises:

[0084] obtaining the encrypted recharge information;

[0085] decrypting the encrypted recharge information to obtain the recharge information;

[0086] modifying the tariff information of the Internet of Things card according to the recharge information.

[0087] According to the foregoing description, in order to ensure the security of the user information, the recharge information is encrypted. After the recharge information is encrypted, the custom recharge interface sends the encrypted recharge information to the Internet of Things card recharge platform. After the Internet of Things card obtains the recharge information sent by the recharge interface, it decrypts the recharge information according to the preset algorithm and obtains the recharge information. Then, the control center of the recharge platform modifies and updates the tariff information of the Internet of Things card in the database according to the obtained recharge information. Specifically, the recharge interface generates encrypted recharge information after confirming that the recharge is completed and sends it to the Internet of Things card recharge platform. The platform obtains the encrypted recharge information through the data acquisition module 101 and sends it to the control center 102 for decryption. The control center 102 modifies and updates the tariff information of the Internet of Things card in the data 104 according to the recharge information obtained after decryption.

[0088] Based on the foregoing description, taking a one-time recharge process as an example, a method for recharging an Internet of Things card according to an embodiment of the application specifically includes the following steps:

[0089] Obtaining flow data of the Internet of Things card;

[0090] According to the flow data, it is determined that the remaining balance of the Internet of Things card is lower than a preset threshold, and a recharge instruction is sent, the recharge instruction including a recharge link;

[0091] Obtaining Internet of Things card information of the Internet of Things card through the recharge link;

[0092] Generating a custom recharge interface through the Internet of Things card information;

[0093] Performing a recharge operation through the custom recharge interface;

[0094] Determining that the custom recharge interface completes the recharge operation, and generating recharge information;

[0095] Modifying the tariff information of the Internet of Things card according to the recharge information;

[0096] Saving the tariff information.

[0097] Exemplarily, in the process of use of the Internet of Things card, the terminal device carrying the Internet of Things card will continuously send the Internet of Things card data packet carrying the terminal device related information to the data acquisition module 101 through the CHF message. Then, the data acquisition module 101 analyzes the Internet of Things card data packet to obtain the terminal device information such as mdn (Internet of Things card number), IMEI (device serial number) and MAC (local area network address) in the data packet and the traffic data of the Internet of Things card. Subsequently, the data acquisition module 101 sends the above device information to the control center 102. The control center 102 verifies the permission related to the Internet of Things card according to the above device information, such as the use state of the Internet of Things card, the type of the Internet of Things card and the operation permission state of the user to which the Internet of Things card belongs. After receiving the traffic data of the Internet of Things card, the control center 102 judges whether the remaining balance of the Internet of Things card is lower than the preset threshold. When the remaining balance of the Internet of Things card is lower than the preset threshold, the control center 102 controls the network center 103 to send a recharge instruction with a recharge link to the terminal device for the user to perform a recharge operation. Then, the sent recharge link accesses the built-in Internet of Things card information module of the device to read the Internet of Things card information therein. The Internet of Things card information includes the Internet of Things card number, and a self-defined recharge interface will be changed accordingly according to the different Internet of Things card numbers, for example, when the obtained Internet of Things card number is 11234567890, the "recharge account" of the self-defined recharge interface will display the Internet of Things card number "11234567890" accordingly. The recharge link can also obtain the name of the user, such as "ABC", which can be displayed in the self-defined recharge interface as "Hello, respected ABC"; or, the remaining balance of the Internet of Things card is obtained and displayed in the recharge interface to enable the user to further understand the recharge information. Subsequently, the user can perform an interactive operation (such as clicking, touching, gesture, input box input, drop-down menu selection, etc.) on the display interface to trigger a corresponding operation instruction to the recharge interface, and the recharge interface confirms the recharge operation after receiving the operation instruction, and then returns the recharge result to the recharge interface to enable the user to understand the recharge result.

[0098] From the above content, it can be known that the application determines that the remaining balance of the Internet of Things card is lower than the preset threshold by obtaining the traffic data of the Internet of Things card, and then sends a recharge instruction including a recharge link, and then obtains the Internet of Things card information of the Internet of Things card through the recharge link, and generates a self-defined recharge interface through the Internet of Things card information, and then performs a recharge operation through the self-defined recharge interface. Through this method, the Internet of Things card information in the terminal device can be read, and the Internet of Things card number therein can be analyzed, thereby eliminating the operation of the user inputting the Internet of Things card number when recharging and avoiding the situation that the user cannot recharge because he forgets the Internet of Things card number.
