[0043] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0044] Reference Figure 1The embodiment of the present invention provides a software method for batch remote upgrade based on MQTT, which is applied to a management terminal and specifically includes the following steps:

[0045] Step S100: Acquire device numbers of multiple gateway devices, each of the device numbers is different and the topic subscribed by each gateway device is the MQTT topic corresponding to its own device number.

[0046] Specifically, each gateway device may have its own device number, which may be preset when the gateway device leaves the factory. Moreover, the device number of each gateway device may be different and unique.

[0047] In addition, the MQTT topic subscribed by each gateway device is the MQTT topic corresponding to its own device number, that is, the MQTT topic subscribed by each gateway device is different. Based on this, different instructions can be issued to different MQTT topics. Different gateway devices can receive different instructions and perform corresponding operations, and multiple gateway devices can be managed separately without the need for all gateway devices to be managed together.

[0048] It should be noted that the device number can be input from the input module of the management terminal or read from a pre-stored device number list. Therefore, the process of obtaining the device number may include: obtaining the device number input by the user through the input module, or obtaining the device number stored in an Excel table, or obtaining the device number stored in a database, etc.

[0049] Step S110: receiving an upgrade instruction, wherein the upgrade instruction includes one or more target device numbers specified by a user from the device numbers, and the gateway device corresponding to the target device number is used as the target gateway device.

[0050] Specifically, the user can customize a personalized upgrade plan, select one or more device numbers from the multiple device numbers that have been obtained as target device numbers, and then the management terminal can receive an upgrade instruction determined by the user, which can include the target device number selected by the user.

[0051] Step S120: publishing the upgrade instruction to the MQTT server, so that the MQTT server sends the upgrade instruction and the target program package for software upgrade to the target gateway device through the MQTT topic subscribed by the target gateway device.

[0052] Specifically, after receiving the upgrade instruction, the MQTT server may send the upgrade instruction and the target program package to each target gateway device specified in the upgrade instruction through the MQTT topic subscribed by each target gateway device.

[0053] Different from the existing remote software upgrade solution, the present invention can perform software upgrade on a specific number of gateway devices, thereby realizing personalized upgrade solutions and targeted management.

[0054] In order to let the user know the upgrade status, the present invention can also display a progress bar from receiving the upgrade instruction to completing the software upgrade of the target gateway device on the display interface of the management terminal. The progress bar can be divided into multiple sub-progress bars according to each node, and each time a node is completed, the sub-progress bar corresponding to the node can display completion.

[0055] The above nodes may include: receiving upgrade instructions, the MQTT server sending upgrade instructions and target program packages, and the target gateway device has completed software upgrades.

[0056] The present invention can also add a process of displaying a predicted countdown in the case of displaying a progress bar, which can specifically include:

[0057] S1. After the target gateway device starts software upgrade, a predicted countdown for completing the software upgrade is displayed on the display interface of the management terminal.

[0058] Specifically, the prediction countdown can be freely set by the user. In an optional implementation, the prediction countdown can be determined based on previous upgrade situations.

[0059] S2. If the software upgrade of all the target gateway devices is completed within the predicted countdown, a reminder mark indicating successful operation is displayed on the display interface of the management terminal, and the display of the predicted countdown is closed.

[0060] S3. If there is a target gateway device that has not completed the software upgrade within the set time period, after the predicted countdown ends, a reminder mark indicating that the operation was unsuccessful is displayed on the display interface of the management terminal, and a progress bar is marked for the target gateway device that has not completed the software upgrade.

[0061] Specifically, if some target gateway devices are not online or fail to perform software upgrades, when the predicted countdown ends, a reminder mark indicating that the operation is not completed can be displayed on the display interface of the management terminal, thereby marking the target gateway devices that have not completed the software upgrade and their progress bars. In addition, the location of the target gateway devices that have not completed the software upgrade can also be marked to facilitate repair of the failed target gateway devices.

[0062] In some embodiments of the present invention, the above-mentioned personalized batch software upgrade is implemented by subscribing to the MQTT topic corresponding to the respective device number. The present invention can also implement personalized batch operations by subscribing to the MQTT topic corresponding to the respective device number. Specifically, the following steps can be included:

[0063] S1. Receive batch operation instructions.

[0064] S2. Publish the batch operation instruction to the MQTT server, so that the MQTT server can complete at least one of obtaining the operating information of the target gateway device, restarting the system of the target gateway device, or restarting the software program of the target gateway device through the MQTT topic subscribed by the target gateway device.

[0065] Specifically, through batch operation instructions, the present invention can also view the operation information of a specific gateway device, restart the system or software program, etc. The specific implementation process can refer to the above-mentioned software batch upgrade process, which will not be repeated here.

[0066] Reference Figure 2 The embodiment of the present invention provides another software method based on MQTT batch remote upgrade, which is applied to a target gateway device and specifically includes the following steps:

[0067] Step S200: receiving an upgrade instruction and a target program package sent by the MQTT server.

[0068] Specifically, the upgrade instruction and the target program package sent by the MQTT server through the MQTT topic subscribed by the MQTT server can be received. The received target program package can be encrypted. After receiving the encrypted target program package, it can be parsed to obtain the parsed target program package.

[0069] Step S210: If the upgrade instruction contains a target device number that is consistent with the device number of the own device, the target program package is verified.

[0070] Specifically, the device number included in the upgrade instruction may be checked. If the device number included in the upgrade instruction is consistent with the device number of the device itself, the resolved target program package may be checked in the chassis.

[0071] Step S220: If the target program package meets the verification requirement, the program package to be upgraded in the local computer is replaced with the target program package that meets the verification requirement.

[0072] Specifically, the local program package to be upgraded may be backed up first, and then the local program package to be upgraded may be replaced with the target program package that meets the verification requirement.

[0073] Furthermore, the upgraded software can be restarted after the target program package is replaced. If the operation fails, the backup program can be run. If the operation succeeds, the upgrade can be considered complete.

[0074] Next, the process of batch remote software upgrade of the present invention will be described with specific examples.

[0075] 1> Assume that there are 30 gateway devices that need software upgrades. Each gateway device is defined with a globally unique device number. The device number can be entered into the device management memory of the management terminal by the manufacturer before leaving the factory for subsequent upgrades and management operations.

[0076] 2> Each gateway device can subscribe to the unique MQTT topic of the gateway device.

[0077] 3>Open the management terminal and connect to the server. At this time, the management terminal has subscribed to the feedback information topics of all gateway devices.

[0078] 4> Select the target gateway device menu to be upgraded through the management terminal, and then click the upgrade program button.

[0079] 5> After clicking the Upgrade button, the management terminal reads the upgrade package information for verification and displays the detailed information of the upgrade package on the management interface.

[0080] 6> After verification, the MQTT topics of 30 gateway devices are automatically published in a loop. Each MQTT topic corresponds to a unique device number. After that, the management interface will display 30 gateway device progress bars.

[0081] 7> The progress bar displays the progress of a series of upgrade steps, such as acceptance of upgrade instructions, inspection, and upgrade, according to the feedback information of each gateway device. That is, each operation performed by the gateway device will be fed back to the management terminal, and the feedback information will be displayed to the administrator in a graphical form.

[0082] 8> Start the upgrade. There can be a predicted countdown to determine whether the upgrade has timed out. When the predicted countdown is over, normal gateway devices will be upgraded successfully. If the gateway device cannot be upgraded successfully because it is not online, you do not need to wait any longer. The management terminal can prompt the gateway device that failed to upgrade.

[0083] 9> If there is a gateway device that fails to upgrade, the administrator can view the device information and device number of the gateway device through the display interface of the management terminal, and then repair the gateway device.

[0084] 10> After the faulty gateway device is repaired successfully, the display interface of the management terminal can perform selective upgrade management on all gateway devices. Select the gateway device that has not been successfully upgraded before and upgrade it.
