[0034] Embodiment 1

[0035] Figure 1 A flowchart of a cloud-edge-terminal collaboration method for the power Internet of Things is provided for the first embodiment of the present invention. This embodiment is applicable to situations in the power Internet of Things where high-priority and low-priority events need to be efficiently processed. The method can be executed by a cloud-edge-terminal collaboration device for the power Internet of Things. The cloud-edge-terminal collaboration device for the power Internet of Things can be implemented in the form of hardware and / or software, and optionally, can be implemented by an electronic device, which can be a mobile terminal, a PC or a server, etc.

[0036] like Figure 1 As shown, the method is applied to a cloud center system and may specifically include:

[0037] S110. Receive an event processing request corresponding to an event to be processed reported by a terminal device in the power Internet of Things, determine the event category of the event to be processed and the device identification of the terminal device, wherein the event category is associated with the urgency of the event and / or the importance of the event.

[0038] Among them, the power Internet of Things can be understood as connecting various power devices through the Internet to achieve data exchange and remote control between power devices. It can be understood that the application of power Internet of Things technology can improve the efficiency of power grid operation and enhance the reliability and safety of the power system. The terminal device can be understood as various intelligent devices installed on site in the power Internet of Things, such as smart meters or sensors. The terminal device is responsible for collecting the operation data of the power system and can send data or requests to the cloud center system. The event processing request can be understood as the information sent to the cloud center system when the terminal device detects a specific situation or anomaly, requesting corresponding processing. The event processing request may include but is not limited to fault reports and maintenance requests. The event category can be understood as dividing the event into different categories according to its nature. The event category is associated with the urgency of the event and / or the importance of the event. Exemplarily, the event category may include but is not limited to important and urgent event categories, important and non-urgent event categories, urgent and non-important event categories, and non-important and non-urgent event categories. The device identifier can be understood as a unique identifier of the terminal device, which is used to identify the terminal device in the power Internet of Things. The device identifier may include but is not limited to a physical address, a serial number or other forms of coding. To ensure the safe and stable operation of the power Internet of Things, strict security verification must be performed on the access terminal devices. This can effectively prevent malicious devices from accessing the network and avoid security risks such as data leakage and network attacks.

[0039] In order to ensure the safe and stable operation of the power Internet of Things, strict security verification can be performed on the terminal devices to be connected. This can effectively prevent malicious devices from accessing the network and avoid security risks such as data leakage and network attacks. Therefore, based on the above scheme, optionally, before receiving the event processing request corresponding to the event to be processed reported by the terminal device in the power Internet of Things, it also includes: performing security verification on the terminal device to be connected to the power Internet of Things, and connecting the terminal device to the power Internet of Things if the terminal device passes the security verification.

[0040] Among them, the security verification can be understood as a check on the terminal device before allowing it to access the power Internet of Things to ensure the working status of the terminal device.

[0041] As an optional implementation of an embodiment of the present invention, when the power Internet of Things receives an access request from a terminal device, the device attribute information of the terminal device to be connected to the power Internet of Things is checked to verify its legitimacy. The check of the device attribute information may include checking the unique identifier of the device such as the MAC address and serial number, and / or verifying the security credentials such as the digital certificate or password of the device. Further, when the device attribute information is verified, the security performance of the terminal device will be tested. The detection of security performance may include checking whether the device has known vulnerabilities and / or whether malware is installed. When the security performance test is passed, the terminal device may be further assigned access rights based on the security verification results of the terminal device to determine which network resources the device can access, which operations it can perform, etc. After completing the above verification, the terminal device will be allowed to access the power Internet of Things. At this point, the terminal device can start communicating and exchanging data with other devices in the network.

[0042] On the basis of the above scheme, optionally, the security verification of the terminal device to be connected to the power Internet of Things includes: detecting the working status of multiple device components of the terminal device to be connected to the power Internet of Things; when it is detected that the device component whose working status is a faulty status and the device component is a preset component, determining that the terminal device has not passed the security verification; when it is detected that the device component whose working status is a faulty status and the device component is not a preset component, or when the device component whose working status is not detected as a faulty status, determining that the terminal device has passed the security verification.

[0043] Among them, the working state can be understood as the current operating state of the device component, and the working state can be a normal working state or a fault state, etc. The fault state can be understood as the state when the device component cannot work normally, indicating that the component is faulty. The preset component can be understood as a device component that is specially designated as a key component during the security verification process. The working state of the preset component directly affects the overall security and reliability of the terminal device. Exemplarily, the communication module can be regarded as a preset component, because the failure of the communication module may cause the terminal device to be unable to communicate with the cloud center.

[0044] In an optional implementation, a health check module is set up inside the terminal device to perform status detection on each device component regularly or on demand, and the detection result includes the current working status (normal status or faulty status) of each device component; a preset component list is set up in the cloud center system, listing device components that are considered to be key components, such as communication modules, main control chips, and encryption modules, etc. The working status of device components will affect the security of the terminal device; the preset component list can be managed through a configuration file or a database; the cloud center system receives the working status of each device component reported by the terminal device, and checks whether any preset component is in a faulty state according to the preset component list; when a device component is detected to be in a faulty state, it is determined that the terminal device has failed the security verification; when a device component in a faulty state is detected and the corresponding device component is not a preset component, it is determined that the terminal device has passed the security verification.

[0045] The above scheme can effectively detect the working status of multiple device components of the terminal device, and determine whether the terminal device has passed the security verification based on the status of the preset components, ensuring that terminal devices that meet safety standards can access the power Internet of Things, thereby improving the safety and reliability of the entire system.

[0046] On the basis of the above scheme, optionally, after the event processing request corresponding to the event to be processed reported by the terminal device in the receiving power Internet of Things, it also includes: when the event category is the third category, determining the event processing method corresponding to the event to be processed, and sending the event to be processed, the event processing method and the device identification to the edge device of the cloud center system for processing, so that the edge device processes the event to be processed according to the event processing method; when receiving the event processing result corresponding to the event to be processed and the device identification reported by the edge device, the event processing result is fed back to the terminal device according to the device identification.

[0047] Among them, the third category can be understood as an unimportant and non-urgent event category. The event processing method can be understood as a pre-defined processing step for a specific event category. Exemplarily, the event processing method may include but is not limited to restarting the device, sending an alarm, and recording a log. The edge device can be understood as a computing node located near the source of data generation, which can perform some data processing tasks, reduce data transmission delays, and improve response speed. Edge devices locally process some tasks that do not require a large amount of computing resources, which can be used to reduce the burden on the cloud center system.

[0048] It is understandable that the third category of pending events is neither urgent nor important and can be given a lower priority for processing. For the third category of pending events, the cloud center system will determine the appropriate event processing method and send the event processing method together with the pending event and device identification to the edge device, instructing the edge device to process the pending event according to the event processing method.

[0049] The above scheme, by sending the third category of pending events, their event processing methods and device identifications to the edge device for processing, can not only effectively reduce the burden on the cloud center system and improve the response speed, but also ensure that the events are handled in a timely and appropriate manner. After the edge device completes the processing locally, it feeds back the event processing results to the cloud center system, and the cloud center system returns the results to the terminal device according to the device identification, ensuring the accurate transmission of information and closed-loop management, and improving the overall operation efficiency and reliability of the power Internet of Things.

[0050] S120. When the event category is the first category, call the system resources in the cloud center system to process the event to be processed, and feed back the event processing result of the event to be processed to the terminal device according to the device identifier.

[0051] The first category can be understood as the event category that needs to be quickly processed by the cloud center system by directly calling system resources. The first category of pending events has a high degree of urgency and importance. The system resources can be understood as the hardware and software resources that can be used to execute the pending events in the cloud center system. For example, the system resources may include but are not limited to computing power, storage space, and network bandwidth.

[0052] S130. When the event category is the second category, the event to be processed and the device identifier are sent to the edge device of the cloud center system for processing. Upon receiving the event processing result and the device identifier corresponding to the event to be processed reported by the edge device, the event processing result is fed back to the terminal device according to the device identifier.

[0053] Among them, the second category can be understood as the category of events processed by the edge devices of the cloud center system. Compared with the first category, the second category of events has a lower degree of urgency or importance, and can be processed in a timely manner closer to the data source (i.e., the edge device) to reduce dependence on the central system and reduce its burden. The second category may include important but not urgent events, urgent but not important events, etc. The edge device can be understood as a device located between the cloud center system and the terminal device, which can perform preliminary processing on some data locally, thereby reducing data transmission delays and speeding up response speed.

[0054] On the basis of the above scheme, optionally, after sending the event to be processed and the device identifier to the edge device of the cloud center system for processing, it also includes: detecting the event processing status of the event to be processed by the edge device, wherein the event processing status is used to characterize whether the event to be processed is in an abnormal processing state; when the event to be processed is in an abnormal processing state, determining an event processing method corresponding to the abnormal processing state, and sending the event processing method to the edge device, so that the edge device processes the event to be processed according to the event processing method.

[0055] Among them, the event processing status can be understood as the status of the processing progress and results of the pending event on the edge device. Exemplarily, the event processing status can be used to characterize whether the pending event is in an abnormal processing state. The abnormal processing status can be understood as an abnormal situation occurring during the processing of the pending event on the edge device. Exemplarily, the abnormal processing status can include but is not limited to processing timeout, processing failure, and insufficient resources.

[0056] The above scheme can detect and handle abnormal situations in a timely manner by detecting the event processing status of the edge device for the event to be processed. When it is detected that the event is in an abnormal processing state, it will determine and send the corresponding event processing method to guide the edge device to perform correct processing. This not only improves the reliability and efficiency of event processing, reduces delays and errors caused by abnormal processing, but also enhances the overall stability and responsiveness of the system, ensuring that the terminal devices in the power Internet of Things can operate normally.

[0057] The technical solution of the embodiment of the present invention determines the event category of the event to be processed and the device identification of the terminal device by receiving an event processing request corresponding to the event to be processed reported by the terminal device in the power Internet of Things. Since the event category is associated with the urgency of the event and / or the importance of the event, priority processing of key events can be achieved; then, when the event category is the first category, the system resources in the cloud center system are called to process the event to be processed, and the event processing result of the event to be processed is fed back to the terminal device according to the device identification, so that high-priority events can be processed by the cloud center system and data transmission delay can be reduced; when the event category is the first category, the system resources in the cloud center system are called to process the event to be processed, and the event processing result of the event to be processed is fed back to the terminal device according to the device identification, so that high-priority events can be processed by the cloud center system and data transmission delay can be reduced; In the case of the second category, the event to be processed and the device identification are sent to the edge device of the cloud center system for processing. When the event processing result corresponding to the event to be processed and the device identification reported by the edge device are received, the event processing result is fed back to the terminal device according to the device identification. This can reduce the amount of data transmission when low-priority events are processed on the edge device, alleviate network bandwidth pressure, and solve the problem in related technologies that all events are processed by the cloud center system, resulting in overload of cloud center system resources and high network bandwidth pressure. Through reasonable event classification and processing strategies, the resource utilization efficiency, response speed and system reliability of the power Internet of Things are significantly improved.

[0058] Embodiment 2

[0059] Figure 2 A flowchart of a cloud-edge collaboration method for electric power Internet of Things provided in Embodiment 2 of the present invention, this embodiment is a further supplement to the above embodiments. Optionally, after the event to be processed and the device identifier are sent to the edge device of the cloud center system for processing, it also includes: detecting the event processing status of the event to be processed by the edge device, wherein the event processing status is used to characterize whether the event to be processed is in an abnormal processing state; when the event to be processed is in an abnormal processing state, the event category of the event to be processed is adjusted to the first category, the edge device stops processing the event to be processed, and the system resources in the cloud center system are called to process the event to be processed. For specific implementation methods, please refer to the description of this embodiment. Among them, the technical features that are the same or similar to the above embodiments are not repeated here.

[0060] like Figure 2 As shown, the method may specifically include:

[0061] S210, receiving an event processing request corresponding to an event to be processed reported by a terminal device in the power Internet of Things, determining the event category of the event to be processed and the device identification of the terminal device, wherein the event category is associated with the urgency of the event and / or the importance of the event.

[0062] S220. When the event category is the first category, call the system resources in the cloud center system to process the event to be processed, and feed back the event processing result of the event to be processed to the terminal device according to the device identifier.

[0063] S230. When the event category is the second category, the event to be processed and the device identifier are sent to the edge device of the cloud center system for processing, and the event processing status of the event to be processed by the edge device is detected, wherein the event processing status is used to characterize whether the event to be processed is in an abnormal processing state.

[0064] Based on the above solution, the edge device not only processes some tasks that do not require a large amount of computing resources locally, but also detects the event processing status in real time through preset abnormal detection conditions. Optionally, the event processing status of the edge device for the event to be processed includes:

[0065] When a preset abnormality detection condition is met, the event processing state of the edge device for the event to be processed is determined as an abnormal processing state; wherein the abnormality detection condition includes:

[0066]

[0067] Wherein, H represents the standard data of the event to be processed, N represents the real-time data of the event to be processed processed in real time by the edge device, and T h Indicates the standard processing time of the pending event, T n represents the total time length of the edge device processing the event to be processed, μ represents the weight of the event to be processed, and δ is a preset constant.

[0068] Among them, the abnormal detection condition can be understood as a condition for judging whether the processing of the event to be processed by the edge device is in an abnormal state. The standard data can be understood as the processing data that the event to be processed should reach under normal circumstances according to historical data or preset standards, which is used to compare the actual processing data and evaluate whether the processing is normal. The actual data can be understood as the data generated by the edge device when actually processing the event to be processed. The standard processing time can be understood as the processing time that the event to be processed should reach under normal circumstances according to historical data or preset standards, which is used to compare the actual processing time and evaluate whether the processing is normal. The preset constant can be understood as a threshold for judging the abnormal processing state. It can be understood that when the calculation result of the abnormal detection formula is greater than or equal to this preset constant, it is judged that the event processing state is in an abnormal processing state.

[0069] The above scheme, by introducing abnormal detection conditions, can detect in real time the processing status of the edge device for the second category of pending events. When an abnormal processing status is detected, it can promptly discover and take corresponding measures to ensure the accuracy and timeliness of event processing. It not only improves the robustness and reliability of the system, but also reduces delays and errors caused by abnormal processing, thereby improving the overall operating efficiency of the power Internet of Things.

[0070] S240. When the event to be processed is in an abnormal processing state, the event category of the event to be processed is adjusted to the first category, the edge device stops processing the event to be processed, and the system resources in the cloud center system are called to process the event to be processed.

[0071] It is understandable that when a pending event is in an abnormal processing state, it means that the edge device may not be able to process the pending event normally, or processing the event may lead to some adverse consequences (such as device overload, data loss, etc.). In this case, the event category of the pending event is adjusted to the first category, so that the pending event has a higher priority or requires a more special processing method; then, the edge device stops processing the pending event; finally, the system resources in the cloud center system are called to process the pending event, because the cloud center system usually has more powerful processing capabilities and more resources.

[0072] S250: When receiving the event processing result and the device identification reported by the edge device and corresponding to the event to be processed, feed back the event processing result to the terminal device according to the device identification.

[0073] The technical solution of the embodiment of the present invention detects the processing status of the second category of pending events by the edge device in real time, and uses the exception detection condition to determine whether the pending events are abnormal. When the abnormal processing status is detected, the event category is adjusted to the first category, the processing of the edge device is stopped, and the resources of the cloud center system are called for processing. This not only can timely discover and handle abnormal situations, avoiding problems caused by edge device processing failures, but also improves the response speed and processing efficiency of the system, ensures the timely processing of high-priority events, and improves the overall stability and reliability of the power Internet of Things.

[0074] Embodiment 3

[0075] Figure 3 This is a schematic diagram of the structure of a cloud-edge-end collaboration device for the power Internet of Things provided in the third embodiment of the present invention. Figure 3 As shown, the device is configured in a cloud center system, including: an event request receiving module 310, a cloud event processing module 320, and an edge side event processing module 330.

[0076] Among them, the event request receiving module 310 is used to receive an event processing request corresponding to the event to be processed reported by the terminal device in the power Internet of Things, determine the event category of the event to be processed and the device identification of the terminal device, wherein the event category is associated with the urgency of the event and / or the importance of the event; the cloud event processing module 320 is used to call the system resources in the cloud center system to process the event to be processed when the event category is the first category, and feedback the event processing result of the event to be processed to the terminal device according to the device identification; the edge side event processing module 330 is used to send the event to be processed and the device identification to the edge device of the cloud center system for processing when the event category is the second category, and when receiving the event processing result corresponding to the event to be processed and the device identification reported by the edge device, feedback the event processing result to the terminal device according to the device identification.
