[0050] In addition, numerous specific details are provided in the following detailed description to better illustrate the present invention. Those skilled in the art will appreciate that the present invention can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art have not been described in detail in order to highlight the main points of the present invention.

[0051] As described above in the background technology, the inventors have found that:

[0052] The current silent upgrade solution for power systems is not yet perfect, and it is impossible to perform efficient silent upgrades without affecting the normal use of equipment.

[0053] Based on this, an embodiment of the present invention proposes a method, device, equipment and storage medium for silent upgrade of an electric power system. The method for silent upgrade of an electric power system fragments the silent upgrade task when the silent upgrade task of the target electric power system is triggered to obtain multiple subtasks of different types. After obtaining the occupancy rate of key system resources by user behavior based on the real-time collected key system resources analysis of the target electric power system, the method predicts the resource occupancy degree of the target electric power system based on the occupancy rate, and selects the corresponding silent upgrade mode based on the resource occupancy degree in a pre-set independent silent upgrade link to silently upgrade the target electric power system. In this way, the silent upgrade mode can be scheduled in real time based on the change in the occupancy rate of key system resources by user behavior, and the upgrade of different types of subtasks can be completed successively, thereby reducing the system resource occupancy of the target electric power system during the silent upgrade process, and thus being able to perform efficient silent upgrades without affecting the normal use of equipment in the target electric power system.

[0054] Specifically, this embodiment will be described from the perspective of a power system silent upgrade device, which can be integrated into a power system silent upgrade device. That is, the power system silent upgrade method of the embodiment of the present invention can be executed by the power system silent upgrade device.

[0055] The following detailed description is provided in conjunction with the accompanying drawings. This embodiment uses the silent upgrade device for a power system as an example. It should be noted that the order in which the following embodiments are described does not limit the preferred order of the embodiments. Although the flowcharts illustrate a logical order, in some cases, the steps shown or described may be performed in a different order than that shown in the accompanying drawings.

[0056] Please refer to Figure 1 The specific process of the power system silent upgrade method can be as follows: Step S101 to Step S104, wherein:

[0057] Step S101 : in response to triggering a silent upgrade task of a target power system, fragmenting the silent upgrade task to obtain a plurality of subtasks of different types.

[0058] The target power system is the power system on which the power system silent upgrade is to be performed in the embodiment of the present invention. The target power system may be one or more.

[0059] Specifically, the silent upgrade task is fragmented to obtain multiple subtasks of different types, which means that the silent upgrade task is decomposed into multiple subtasks of different types, wherein different types of subtasks have different task sizes, and subtasks of the same type have the same task size.

[0060] It can be understood that the embodiment of the present invention fragments the silent upgrade task, which can decompose the execution of the silent upgrade task into the execution of several subtasks, thereby avoiding the situation where a large amount of tasks are upgraded at one time and occupy too many system resources, affecting the normal use of the equipment in the target power system.

[0061] To make the task amounts of the subtasks based on the silent upgrade task more reasonable, that is, more suitable for the power system silent upgrade method according to embodiments of the present invention, in some embodiments, after the silent upgrade task is fragmented, the silent upgrade task is split into multiple first subtasks, multiple second subtasks, and multiple third subtasks. The task amount of the first subtask is smaller than that of the second subtask, and the task amount of the second subtask is smaller than that of the third subtask.

[0062] Therefore, the embodiment of the present invention makes the fragmented processing of silent upgrade tasks more suitable for this solution by rationally planning subtasks of different task sizes, and can subsequently schedule different types of subtasks for upgrades based on real-time status, thereby further improving the efficiency of silent upgrades without affecting the normal use of equipment in the target power system.

[0063] In some embodiments, the triggering conditions of the silent upgrade task of the target power system are described. In this embodiment, the power system silent upgrade method may also include:

[0064] If it is confirmed that the equipment in the target power system is idle, the current power of the equipment in the target power system is greater than the preset power, and the network status of the target power system meets the preset conditions, the silent upgrade task of the target power system is triggered.

[0065] That is, the triggering conditions for the silent upgrade task of the target power system are:

[0066] The equipment in the target power system is idle, the current power of the equipment in the target power system is greater than the preset power, and the network status of the target power system meets the preset conditions.

[0067] It can be understood that the embodiment of the present invention, by setting the trigger conditions for the silent upgrade task of the target power system as described above, can minimize the disturbance to users when performing the silent upgrade of the target power system, and ensure that the device power and network status are sufficient to support the silent upgrade operation, thereby improving the user experience of the silent upgrade function.

[0068] Optionally, the preset power level can be 50%, and the network status meeting the preset conditions can be at least one of the following: network delay is less than a preset delay threshold (such as 5ms), network jitter is less than a preset network jitter threshold (such as 4ms), packet loss rate is less than a preset packet loss rate threshold (such as 3%), and network bandwidth is greater than a preset network bandwidth threshold (such as 10Mbps).

[0069] In some embodiments, the integrity and legality of the upgrade files related to the silent upgrade task are also verified.

[0070] Step S102 : collecting key system resources of the target power system in real time, and analyzing the occupancy rate of the key system resources by user behaviors based on the key system resources.

[0071] The key system resources of the target power system refer to resources related to the use of the target power system and the devices in the target power system. The more intensively a user uses the target power system and the devices in the target power system, the more key system resources are occupied. This embodiment of the present invention analyzes the occupancy rate of the key system resources of the target power system as a result of user behavior, facilitating the subsequent rational scheduling of silent upgrade tasks based on this occupancy rate, thereby reducing the impact of the silent upgrade process on the use of the devices in the target power system.

[0072] In some embodiments, step S102 may include:

[0073] Step S1021 : collecting key system resources based on a preset first time interval, and analyzing the occupancy rate of the key system resources by user behaviors based on the key system resources.

[0074] Step S1022: capturing the occupancy rates obtained from the most recent m analyses based on a preset second time interval to obtain a continuous occupancy rate.

[0075] Wherein, m is a preset value and a positive integer; the second time interval is greater than or equal to the first time interval, and the second time interval is less than or equal to twice the first time interval.

[0076] Exemplarily, m=5, that is, the occupancy rates obtained from the last five analyses are captured based on the preset second time interval to obtain the continuous occupancy rate.

[0077] Specifically, the embodiment of the present invention monitors various types of key system resources of the target power system and the equipment therein in real time, collects the key system resources once every first time interval, and transmits the key system resources to the terminal for analysis to obtain the occupancy rate of the key system resources caused by user behavior. At the same time, the embodiment of the present invention captures the occupancy rate obtained from the most recent m analyses at every second time interval to obtain a continuous occupancy rate, which is recorded as X n ,X n-1 ,…,X n-m+1 When m=5, the continuous occupancy rate is X n ,X n-1 ,X n-2 ,X n-3 ,X n-4 .

[0078] It is understood that the embodiment of the present invention analyzes the occupancy rate of key system resources caused by user behavior through steps S1021-S1022 and captures the continuous occupancy rate, facilitating the subsequent formulation of a more accurate and reliable silent upgrade strategy based on the continuous occupancy rate, further improving the efficiency and reliability of the silent upgrade without affecting the normal use of the equipment in the target power system. Furthermore, the embodiment of the present invention collects key system resources and analyzes the occupancy rate at a first time interval, and captures the continuous occupancy rate at a second time interval, wherein the second time interval is greater than or equal to the first time interval and less than or equal to twice the first time interval. This can avoid the situation where the captured continuous occupancy rate is the same as the previously captured continuous occupancy rate when the second time interval is less than the first time interval, thereby reducing the accuracy and reliability of the silent upgrade strategy subsequently formulated based on the continuous occupancy rate. It can also avoid the situation where the captured continuous occupancy rate is not representative of the timeliness of the captured continuous occupancy rate due to the second time interval being too long, thereby reducing the accuracy and reliability of the silent upgrade strategy subsequently formulated based on the continuous occupancy rate. Thus, the embodiment of the present invention can improve the accuracy and reliability of the captured continuous occupancy rate and avoid the adverse effects of abnormal data on subsequent prediction results and the reliability of silent upgrades.

[0079] Step S103 : predicting the resource occupancy level of the target power system based on the occupancy rate.

[0080] Specifically, the embodiment of the present invention predicts the resource occupancy rate of the target power system based on the occupancy rate of key system resources obtained by real-time analysis of user behavior in step S102, so as to facilitate the subsequent selection of an appropriate silent upgrade strategy based on the resource occupancy rate and reduce the impact of the silent upgrade process on the normal use of the target power system and its equipment.

[0081] Optionally, an embodiment of the present invention can predict the resource occupancy level of the target power system based on a preset machine learning model, which is pre-trained to output the predicted resource occupancy level of the target power system when the occupancy rate is input.

[0082] In some embodiments, the resource occupancy level includes an idle state, a light load state, a medium load state, and a heavy load state. In order to more accurately predict the resource occupancy level of the target power system based on the occupancy rate, in this embodiment, step S103 may include:

[0083] Step S1031: Substitute the continuous occupancy rate into a preset prediction formula to obtain a prediction factor.

[0084] Step S1032, determining whether the occupancy rate is increasing based on the continuous occupancy rate;

[0085] If it is confirmed that the prediction factor is less than a preset first threshold, the resource occupancy level is a light load state; if it is confirmed that the prediction factor is greater than or equal to the first threshold and less than a preset second threshold, the resource occupancy level is a medium load state; if it is confirmed that the prediction factor is greater than or equal to the second threshold and less than a preset third threshold, or the prediction factor is greater than or equal to the third threshold, the resource occupancy level is a heavy load state;

[0086] If not, if the prediction factor is confirmed to be less than the first threshold, the resource occupancy level is in an idle state; if the prediction factor is confirmed to be greater than or equal to the first threshold and less than the second threshold, the resource occupancy level is in a light load state; if the prediction factor is confirmed to be greater than or equal to the second threshold and less than the third threshold, the resource occupancy level is in a medium load state; if the prediction factor is confirmed to be greater than or equal to the third threshold, the resource occupancy level is in a heavy load state.

[0087] The first threshold is less than the second threshold, the second threshold is less than the third threshold, and the resource occupancy levels are arranged in order from the smallest to the smallest, i.e., the idle state, the light-load state, the medium-load state, and the heavy-load state. It is understood that the first threshold is a threshold between the idle state and the light-load state, the second threshold is a threshold between the light-load state and the medium-load state, and the third threshold is a threshold between the medium-load state and the heavy-load state.

[0088] Specifically, the prediction formula is:

[0089]

[0090] Where Y is the prediction factor; λ1,λ2…λ m It is a preset weighting coefficient, which has a preset value and decreases in sequence. That is, the farther the occupancy is from the current time, the smaller the weighting coefficient corresponding to it is. Taking m=5 as an example, the value range of λ1 is 0.9-1, the value range of λ2 is 0.7-0.8, the value range of λ3 is 0.5-0.6, the value range of λ4 is 0.3-0.4, and the value range of λ5 is 0.1-0.2.

[0091] Therefore, the embodiment of the present invention obtains a prediction factor based on continuous occupancy prediction, and determines the resource occupancy level based on whether the occupancy level increases and the specific value of the prediction factor, so as to obtain a more accurate resource occupancy level, thereby making the subsequent silent upgrade strategy determined based on the resource occupancy level more accurate and reliable, and further improving the efficiency and reliability of the silent upgrade without affecting the normal use of the equipment of the target power system.

[0092] In some embodiments, determining whether the occupancy rate is increasing based on the consecutive occupancy rates may include:

[0093] If the continuous occupancy rate is n >X n-1 >…>Xn-m+1 , it is determined that the occupancy rate has increased.

[0094] Step S104 : In a preset independent silent upgrade link, a corresponding silent upgrade mode is selected based on the resource occupancy level to perform silent upgrade on the target power system.

[0095] In each silent upgrade mode, at most one type of subtask is upgraded.

[0096] Specifically, the embodiment of the present invention can pre-establish an independent silent upgrade link based on the dedicated communication channel or backup communication channel within the target power system, and subsequently perform a silent upgrade of the target power system in the independent silent upgrade link, thereby reducing the impact of the silent upgrade of the target power system on normal communication. At the same time, the embodiment of the present invention selects a corresponding silent upgrade mode based on the resource occupancy level predicted in the aforementioned steps to perform a silent upgrade on the target power system, and upgrades at most one type of subtask before each change in resource occupancy level, and then completes the upgrade of all subtasks in the silent upgrade task in succession, thereby enabling a highly efficient silent upgrade without affecting the normal use of the equipment in the target power system.

[0097] In some embodiments, the silent upgrade task includes the plurality of first subtasks, the plurality of second subtasks, and the plurality of third subtasks as described above. In this embodiment, step S104 of selecting a corresponding silent upgrade mode based on the resource occupancy level to perform a silent upgrade on the target power system may include:

[0098] If the resource usage is idle, the third subtask is upgraded;

[0099] If the resource usage is in a light load state, the second subtask is upgraded;

[0100] If the resource usage is in a medium load state, the first subtask is upgraded;

[0101] If the resource usage is overloaded, the silent upgrade task will be paused.

[0102] Therefore, the embodiment of the present invention can upgrade the third subtask, the second subtask, and the first subtask when the resource occupancy level is in the idle state, the light load state, and the medium load state, respectively, and suspend the silent upgrade task when the resource occupancy level is in the heavy load state, and finally complete the upgrade of all subtasks in the silent upgrade task one after another. At the same time, it has a high silent upgrade efficiency and will not affect the normal use of the equipment in the target power system.

[0103] In some embodiments, the target power system may also be silently upgraded based on a multi-phase atomic commit protocol.

[0104] The multi-phase atomic commit protocol is suitable for distributed component upgrades. It is understood that embodiments of the present invention silently upgrade the target power system based on the multi-phase atomic commit protocol, ensuring that the target power system maintains a consistent state at any interruption point.

[0105] In some embodiments, the power system silent upgrade method may further include:

[0106] During the execution of the silent upgrade task, the upgrade data of the silent upgrade task is stored in segments based on the non-volatile memory and the flash memory, and an upgrade log file is generated.

[0107] The upgrade log file supports fine-grained operation recording and fast rollback.

[0108] Therefore, the embodiment of the present invention stores the upgrade data of the silent upgrade task in segmented form based on non-volatile memory and flash memory during the silent upgrade process and generates an upgrade log file. This can not only protect the files instantaneously when the target power system loses power, but also can promptly roll back to the key position of the upgrade or the corresponding position to continue updating when the target power system resumes the execution of the silent upgrade task after the power failure, thereby avoiding data loss.

[0109] In some embodiments, after step S104, the power system silent upgrade method may further include:

[0110] Test the various functions of the upgraded target power system, optimize the functions, and check the consistency of the target power system data.

[0111] To sum up, the embodiment of the present invention fragments the silent upgrade task of the target power system when it is triggered to obtain multiple subtasks of different types. After obtaining the occupancy rate of key system resources by user behavior based on the real-time collected key system resources analysis of the target power system, the resource occupancy degree of the target power system is predicted based on the occupancy rate, and in a pre-set independent silent upgrade link, the corresponding silent upgrade mode is selected based on the resource occupancy degree to perform a silent upgrade on the target power system. In this way, the silent upgrade mode can be scheduled in real time based on the change in the occupancy rate of key system resources by user behavior, and the upgrade of different types of subtasks can be completed successively, thereby reducing the system resource occupancy of the target power system during the silent upgrade process, and thus being able to perform efficient silent upgrades without affecting the normal use of equipment in the target power system.

[0112] This embodiment also provides a power system silent upgrade device, which can be integrated into the power system silent upgrade equipment. Figure 2 As shown, the power system silent upgrade device may include:

[0113] The fragmentation processing unit 201 is used to fragment the silent upgrade task in response to triggering the silent upgrade task of the target power system to obtain multiple subtasks of different types. Different types of subtasks have different task sizes, and subtasks of the same type have the same task size.

[0115] The prediction unit 203 is configured to predict the resource occupancy level of the target power system based on the occupancy rate.

[0116] The upgrading unit 204 is configured to select a corresponding silent upgrading mode based on resource occupancy in a preset independent silent upgrading link to silently upgrade the target power system, and to upgrade at most one type of subtask in each silent upgrading mode.
