[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Figure 1 Schematic diagram of the process of the management method of the self-service printing intelligent device provided by the present invention. Figure 1 As shown, the method includes the following steps S101 and S102.

[0026] Step 101: In response to a user's input operation, an MQTT protocol message is generated that needs to be sent to one or more self-service printing smart devices, where the MQTT protocol message includes management instructions for the self-service printing smart devices.

[0027] As an optional embodiment, the user may be the manager or owner of the self-service printing smart device.

[0028] It should be noted that the MQTT protocol is a lightweight message transmission protocol based on the publish / subscribe mode. It mainly works on the TCP / IP protocol family. It is a publish / subscribe message protocol designed for remote devices with low hardware performance and poor network conditions. The MQTT protocol relies on a middleware. The middleware is built on the MQTT cloud server. After the user completes the input operation in the self-service printing smart device management system, the self-service printing smart device management system interacts with the self-service printing smart device through the middleware and obtains information. The self-service printing smart device can execute the corresponding script file through the instructions obtained by the MQTT protocol to interact with the hardware of the self-service printing smart device and complete the instructions.

[0029] It should be noted that self-service printing smart devices often need to respond to user operation requests in real time. The MQTT protocol uses a long connection mechanism to ensure that management instructions can be sent to the device immediately to meet the user's real-time printing and management needs. In addition, self-service printing smart devices may be deployed in places with poor network environments, such as campuses, shopping malls and other public places. The lightweight design of the MQTT protocol can maintain efficient and reliable communication in low-bandwidth and unstable network environments, allowing the device to receive instructions and perform operations normally. At the same time, self-service printing smart devices usually have limited hardware resources, especially in network communications. The low power consumption characteristics and small message overhead of the MQTT protocol can effectively reduce the resource consumption of the device and extend the service life of the device.

[0030] In an exemplary embodiment, the management instruction includes at least one of the following: a device startup instruction, a device shutdown instruction, a device restart instruction, a print instruction, and a device operation log upload instruction.

[0031] As an optional embodiment, when a user (manager) finds that a self-service printing smart device has multiple unprinted tasks, the self-service printing smart device is judged to be in an abnormal state. The manager can enter a restart operation, and the system generates an MQTT protocol message containing a device restart instruction. The restart instruction includes the ID of the target device and the restart operation. The MQTT message is sent to the specified self-service printing smart device through the MQTT cloud server, and the self-service printing smart device performs a remote restart operation after receiving it. After the restart is successful, the self-service printing smart device can also feedback the status to the self-service printing smart device management system through the MQTT protocol.

[0032] As an optional embodiment, after receiving the operation log upload instruction, the device sends the operation log through the MQTT protocol, including information such as the remaining ink level of the printer and the number of sheets of paper. After receiving the operation log, it is determined whether the remaining consumables are lower than a preset threshold. If the remaining consumables are lower than the preset threshold, the maintenance personnel are notified to replenish them in time to ensure that the remaining consumables are sufficient during use and the printing function can be used normally.

[0033] In an exemplary embodiment, in response to the user's input operation, before generating an MQTT protocol message to be sent to one or more self-service printing smart devices, the method further includes: verifying the user's login username and login password based on an encryption verification algorithm, and the formula of the encryption verification algorithm is:

[0034] in, Represents the encrypted ciphertext, Indicates the login password entered by the user, MD5 ( Indicates that the login password entered by the user is The encrypted ciphertext, Indicates the login user name.

[0035] It should be noted that the self-service printing intelligent device management system generates encrypted ciphertext through the above formula, searches for the corresponding stored ciphertext in the database according to the user name, and compares the encrypted ciphertext generated by the formula with the stored ciphertext in the database. If the ciphertext matches successfully, it means that the user's password and account match, which means that the legitimacy verification of the login information is completed, ensuring that the user is an authorized user.

[0036] In an exemplary embodiment, the method further includes: after the user is authenticated, recording the IP address of the user's login, and the IP address is used to identify the user's remote login.

[0037] As an optional embodiment, in order to further enhance the security of the system, the IP address can be verified after the user password is verified. The administrative district of the user's login location is mainly obtained by resolving the IP address used by the user to access the server through the IP address resolved by DNS. Each time you log in, the self-service printing intelligent device management system will record the administrative district code resolved to the IP address of this login, and generate a set of login locations {IP1, IP2...IPn}, where IP1, IP2, IPn represent the administrative district code of the login location recorded each time the user logs in. The set will intelligently determine whether the login location is a common login location after each login.

[0038] In the above embodiment, the dual verification method of password verification and IP address verification can ensure that other users will not mistakenly log in to the self-service printing intelligent device management system, reducing the risk of information leakage.

[0039] Step 102: Send the MQTT protocol message to the MQTT cloud server. The MQTT cloud server is used to send the MQTT protocol message corresponding to each self-service printing smart device to each self-service printing smart device through the subscription channel corresponding to each self-service printing smart device, so that the self-service printing smart device can perform corresponding operations according to the management instructions in the MQTT protocol message.

[0040] It should be noted that the MQTT cloud server is equipped with a middleware, and the self-service printing smart device management system interacts with the self-service printing smart device and obtains information through the middleware.

[0041] In the above embodiment, the user initiates an operation request for the self-service printing smart device through the self-service printing smart device management system, and the system generates a corresponding MQTT protocol message, which contains management instructions, such as printing tasks, device restarts, or consumables status inquiries. The generated MQTT protocol message is sent to the middleware in the MQTT cloud server. The cloud server sends the MQTT message to the corresponding self-service printing smart device through the subscription channel corresponding to each self-service printing smart device. After receiving the message, the self-service printing smart device performs corresponding operations according to the management instructions in the message, such as starting a printing task, restarting the device, or reporting the device status, thereby realizing intelligent management of remote devices.

[0042] It should be noted that each smart device can subscribe to one or more channels, and MQTT protocol messages are published through channels. For example, self-service printing smart device 1 subscribes to channel A, and self-service printing smart device 2 subscribes to channel B. When the MQTT protocol message is channel A, only self-service printing smart device 1 will receive the message, and self-service printing smart device 2 will not be affected.

[0043] In the above embodiment, each self-service printing smart device can subscribe to an independent channel to ensure that the device only receives messages related to itself, and other devices will not be affected. This message routing mechanism avoids unnecessary message interference and improves communication efficiency. In addition, the publish / subscribe mode of the MQTT protocol decouples the communication between the self-service printing smart device and the self-service printing smart device management system. The self-service printing smart device management system does not need to know the specific recipient of the message, it only needs to publish the message to a specific channel. This decoupling enhances the flexibility and scalability of the self-service printing smart device management system. At the same time, security is enhanced. Different self-service printing smart devices receive instructions through independent channels to avoid messages being mistakenly sent or leaked to other self-service printing smart devices. Combined with the password verification and IP verification in the above embodiment, the security of the self-service printing smart device management system is further improved to ensure that sensitive information is only sent to the target self-service printing smart device.

[0044] In the above steps S101-S102, in response to the user's input operation, an MQTT protocol message that needs to be sent to one or more self-service printing smart devices is generated. With the help of the characteristics of the MQTT protocol, the MQTT protocol message can be sent to the MQTT cloud server more efficiently. The MQTT cloud server sends the MQTT protocol message corresponding to each self-service printing smart device to each self-service printing smart device through the subscription channel corresponding to each self-service printing smart device, so that the self-service printing smart device can perform corresponding operations according to the management instructions in the MQTT protocol message. Through the subscription mode of the MQTT protocol, the user's operation can quickly generate and issue management instructions, ensuring that the message is more efficiently delivered to the corresponding self-service printing smart device through the cloud server. Efficient remote management and control of widely distributed self-service printing smart devices is achieved.

[0045] In an exemplary embodiment, the above method also includes: receiving a device operation log uploaded by the self-service printing smart device through the MQTT cloud server.

[0046] As an optional embodiment, the self-service printing smart device can regularly send the device operation log to the MQTT cloud server through the MQTT protocol. Each device subscribes to a dedicated channel and publishes log data to the cloud server through the channel. The log information includes the operating status of the self-service printing smart device, the execution of printing tasks, the usage of consumables, and device failure information. After the MQTT cloud server receives the logs uploaded by the device, it will push these data to the self-service printing smart device management system, and the self-service printing smart device management system will monitor and maintain the device status based on these operation logs.

[0047] In the above embodiment, the operation log of the self-service printing smart device is regularly uploaded to the cloud server through the MQTT protocol, so that the self-service printing smart device management system can monitor the status and operation of the self-service printing smart device in real time, ensure timely detection and response of problems, and improve the operation and maintenance efficiency of the device. The lightweight characteristics of the MQTT protocol ensure that the device log upload process is efficient and saves bandwidth. Even in a poor network environment, the self-service printing smart device can stably upload logs to ensure data integrity.

[0048] In an exemplary embodiment, the above method also includes: based on the device operation log, displaying the device printing information of the self-service printing smart device through a display interface.

[0049] As an optional embodiment, the self-service printing smart device uploads the device operation log to the cloud server through the MQTT protocol. After receiving these logs, the cloud server sends the logs to the self-service printing smart device management system. The self-service printing smart device management system parses and processes these log data, and displays the printing information of the self-service printing smart device through a user-friendly display interface (such as a PC or mobile phone). Users can view the detailed printing records of each device through the display interface of the self-service printing smart device management system. The self-service printing smart device management system can also sort and filter according to the log data, so that users can query the printing status of a specific time period or a specific device.

[0050] In the above embodiment, the user can intuitively view the printing status of each self-service printing smart device through the display interface, which improves the transparency of information. By centrally displaying the printing information of the device, the user can more conveniently monitor and manage multiple devices, reducing the tedious work of manual recording. By displaying detailed printing log information, the user can quickly locate the time point and task of printing anomalies, thereby more efficiently troubleshooting equipment failures.

[0051] The executor of each step in the above method can be a management device of the self-service printing intelligent device, which can be implemented through software and / or hardware. The device can be integrated in an electronic device. The electronic device can be a terminal device (such as a smart phone, a personal computer, etc.), or a server (such as a local server or a cloud server, or a server cluster, etc.), or a processor, or a chip, etc.

[0052] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. In order to better understand the above method, the above process is described below in conjunction with the embodiments, but the technical solutions of the embodiments of the present invention are not limited. Specifically: The present invention provides a self-service printing intelligent device management system based on the Internet of Things, such as Figure 2 , which is a schematic diagram of the structure of the self-service printing intelligent device management system provided by the present invention. The self-service printing intelligent device management system includes a user terminal module, an identity authentication module, a device management module and a device printing information display module. Specifically.

[0053] (1) The user-side module is mainly divided into two modes: PC and mobile phone to manage and operate self-service printing smart devices. Figure 3 FIG. 1 is a schematic diagram of the structure of the user terminal module provided by the present invention. Further, the PC terminal can directly perform setting operations, while the mobile terminal is only used for viewing information and cannot perform setting operations.

[0054] (2) The identity verification module is used to ensure that the user who manages and configures the device is the user authorized by the device owner and to ensure that the user's device is not tampered with by other persons. The identity verification module mainly includes the password verification module and the module of the commonly used login location. Figure 4 As shown, it is a schematic diagram of the structure of the identity authentication module provided by the present invention. Specifically, the password verification module is used to identify the identity of the user. The commonly used login location module is mainly used to identify and verify the user's login location. The user's login location is mainly obtained by resolving the IP address used by the user when accessing the server using the IP address resolved by DNS. The identity authentication module also needs to use an encryption verification algorithm. The principle of the encryption verification algorithm has been explained in detail in the aforementioned embodiment and will not be repeated here.

[0055] (3) The device management module is used to display device information and can remotely power on and off the device and upload operation logs. Users can manage the device's hardware and software through this module. Figure 5It is a schematic diagram of the workflow of the device management module provided by the present invention. The MQTT protocol is based on a middleware. The middleware is built in the MQTT cloud server. After the user completes the input operation in the self-service printing intelligent device management system, the self-service printing intelligent device management system interacts with the intelligent device through the middleware and obtains information. The self-service printing intelligent device can execute the corresponding script file through the instruction obtained by the MQTT protocol to interact with the hardware of the self-service printing intelligent device and complete the instruction.

[0056] (4) The device printing information display module is used to show the user the time points at which the current smart device performed printing operations and the number of pages of the printed files. If a large number of unprinted orders are found in the printing information display module, it can be inferred that the device is abnormal. The device management module can be used to remotely restart the device to repair it. If the restart is ineffective, the device's operation log can also be uploaded to the system to provide users with troubleshooting work for device abnormalities.

[0057] It should be noted that the self-service printing smart device controls the hardware device through the built-in script file, including the acquisition of printing tasks and sending them to the printer, the restart and shutdown of the device itself, etc., which greatly facilitates the users of the device and allows the management of multiple devices without a large amount of manpower. When the device malfunctions, it can be restarted remotely.

The management device of the self-service printing intelligent device described below and the management method of the self-service printing intelligent device described above can be referred to each other.

Through the subscription mode of the MQTT protocol, the user's operation can quickly generate and issue management instructions, ensuring that the message is more efficiently transmitted to the corresponding self-service printing smart device through the cloud server. Efficient remote management and control of widely distributed self-service printing smart devices is realized.
