[0047] As Figure 1 shown, a detection method for keeping alive between a management center and a trusted device in the embodiments of the present application specifically includes the following steps:

[0048] Step 101, start a resource detection thread, obtain resource information of a terminal device through a trusted proxy, and send the resource information of the terminal device to a management platform;

[0049] Step 102: Determine whether the resource information of the terminal device exceeds the limit through the management platform;

[0050] Step 103: When the resource information of the terminal device does not exceed the limit, the management platform confirms that the keep-alive status with the terminal device is normal; otherwise, the management platform generates an alarm message and sends the alarm message to the terminal device.

[0051] The embodiments of the present application can be applied to online inspection of terminal devices, resource detection of terminal devices, system log analysis, etc., to ensure the keep-alive mechanism of terminal devices. The application scenarios of the embodiments of the present application are only exemplified here and are not limited.

[0052] Specifically, the keep-alive mechanism includes:

[0053] 1) The network status of the device, which is divided into online and offline; the network delay and packet loss rate can be detected, and an alarm notification can be sent in time if the network quality does not meet the standard. Detection of the resources of the terminal device: The resources of the terminal device include CPU, memory, and storage information. In management, the dynamic threshold of the resources of the terminal can be set through the page. When the resource usage exceeds the preset threshold, an alarm can be triggered to prompt the administrator of the running status of the terminal device.

[0054] 2) System log analysis: Collect and analyze the system logs of the terminal device, and detect abnormal situations of the terminal device through artificial intelligence big data to detect abnormalities or errors, so as to ensure the running status of the terminal device, thereby achieving the keep-alive mechanism between the terminal device and the management terminal. Regular automatic scanning: Add a timing task function to automatically perform a complete health check, including resource usage, network status, system logs, etc.

[0055] 3) Comprehensive report generation: Regularly generate a comprehensive operation status report and automatically send it to the administrator to assist in decision-making and improving management strategies.

[0056] As Figure 2 shown, the detection method for keep-alive between the trusted management center and the trusted device described in the present application includes the following steps:

[0057] 1) When the terminal device is started for the first time, collect the information of the terminal device and send the information of the terminal device to the management center.

[0058] 2) Start the heartbeat thread, and the trusted agent regularly sends heartbeat packets to the management platform.

[0059] 3) Start the resource detection thread, and the trusted agent sends the CPU, memory, and storage information of the terminal device to the management platform.

[0060] 4) The management platform receives the heartbeat packet to update the interface and regularly checks whether it is online.

[0061] 5) The management platform receives the CPU, memory, and storage information of the terminal device, and determines whether the CPU, memory, and storage information of the terminal device is abnormal. When the CPU, memory, and storage information of the terminal device is abnormal, an alarm message is generated.

[0062] Among them, when the CPU is too high, the storage occupancy is too high, or the space is insufficient, an alarm message is generated. Multiple intelligent solutions are adopted, and multi-channel alarm notifications are sent: Consider sending alarm messages to the administrator through different channels (such as email, SMS, APP push, etc.) to ensure that important notifications can be received in a timely manner. Automatic response mechanism: After receiving a specific type of alarm, some response measures can be automatically triggered, such as restarting the service, releasing some resources, or switching to a standby device to ensure the normal operation of the terminal device.

[0063] 6) Store the alarm message in the database.

[0064] Optionally, the management platform determines whether the resource information of the terminal device is over-limit, including:

[0065] The management platform determines the usage of any one of the resources according to the resource information; among them, the resource information of the terminal device includes the CPU information, memory information, and storage information of the terminal device;

[0066] When the resource information of the terminal device is not over-limit, the management platform confirms that the keep-alive state with the terminal device is normal, including:

[0067] When any one of the resources does not exceed its corresponding upper limit, the management platform confirms that the keep-alive state with the terminal device is normal.

[0068] Optionally, the method further includes:

[0069] The terminal device starts a heartbeat thread and regularly sends a heartbeat packet to the management platform through a trusted proxy;

[0070] The management platform receives the heartbeat packet;

[0071] Detect the online status of the terminal device based on the heartbeat packet, and / or the management platform determines the online operation status of the terminal device based on the heartbeat status information in the heartbeat packet.

[0072] In some embodiments, starting a heartbeat thread is a key measure. The trusted agent periodically sends heartbeat packets to the management platform. The heartbeat packet contains the online status information of the device. The management platform receives these heartbeat packets in real time and uses the status information therein to detect whether the terminal device is in a good online state. When an abnormality appears in the heartbeat information, the system will take corresponding countermeasures.

[0073] Optionally, the method further includes:

[0074] When starting a resource detection thread and in the case where the terminal device is started for the first time, the trusted agent obtains the configuration information, hardware parameters, and software version information of the terminal device;

[0075] The trusted agent sends the configuration information, hardware parameters, and software version information of the terminal device to the management platform for filing.

[0076] Specifically, when the terminal device is started for the first time, the trusted agent automatically collects the configuration information, hardware parameters, and software version information of the device and sends this information to the management platform for filing. This lays a foundation for subsequent management and monitoring.

[0077] Optionally, the method further includes:

[0078] During the process of monitoring the keep-alive state between the management platform and the terminal device, if the management platform discovers an abnormal situation, it determines an adjustment strategy according to the preset priority of the terminal device;

[0079] The management platform sends the adjustment strategy to the terminal device;

[0080] The terminal device executes the adjustment strategy;

[0081] Wherein, the adjustment strategy includes any one or more of restarting the terminal device, notifying the terminal device to perform a failover, and switching the operating state of the terminal device.

[0082] Optionally, when any one of the resource information does not exceed its corresponding upper limit, the management platform confirms that the keep-alive with the terminal device is normal, including:

[0083] According to the application scenario information and historical data of the terminal device, adjust the usage threshold of each resource in the resource information;

[0084] When any one of the resource information does not exceed the corresponding usage threshold, the management platform confirms that the keep-alive with the terminal device is normal.

[0085] In some other embodiments, during the monitoring process, if the management platform detects an abnormal situation (such as the resource utilization rate exceeding the limit or the device not responding), it will formulate corresponding adjustment strategies according to the preset priorities. For example, it may restart the device, notify for failover, or switch the operating mode, etc. These adjustment strategies can be sent to the terminal device immediately by the management platform to ensure a quick response and reduce the downtime caused by device failures.

[0086] Furthermore, to manage resource usage more flexibly, the management platform can also dynamically adjust the usage threshold of each resource according to the application scenario and historical data of the terminal device. When the usage of a certain resource does not exceed the dynamically adjusted threshold, the normal keep-alive state with the terminal device is still maintained. This mechanism enhances the adaptability of the system, enabling it to actively adjust the operation strategy according to environmental changes.

[0087] In a specific embodiment of the present application, after the terminal device goes online, it starts a resource detection thread, obtains the current resource information, and sends it to the management platform. It starts a heartbeat thread and sends a heartbeat packet to the management platform every set time to confirm the online state of the device. After receiving the resource information of the component, the management platform compares it with the set usage threshold. If the utilization rate of all resources is normal, the keep-alive state is confirmed to be normal. If there is an abnormality, an alarm message is generated. If an abnormality is found, the management platform immediately takes adjustment measures according to the preset priority classification and issues the instruction to the terminal device to ensure the timeliness and effectiveness of the adjustment method. According to the operation feedback and actual usage situation, the usage threshold of the resource is dynamically modified to optimize the device management strategy.

[0088] The embodiments of the present application realize the comprehensive monitoring and optimized management of terminal devices by comprehensively utilizing resource information, heartbeat detection, and an intelligent emergency response mechanism, improving the stability and security of the devices. This mechanism is not only applicable to the management of a single device but also provides a feasible solution for the device management in a large-scale IoT environment.
