Embodiment approach

[0044] The CPU is a key component for edge computing nodes to complete computing tasks, and its operating frequency is a key indicator that determines the CPU's operating speed and power consumption. Increasing the CPU frequency can make the CPU complete calculation tasks faster and consume more energy consumption, and vice versa can achieve the purpose of saving power consumption. The adjustment of the current CPU frequency is implemented by the operating system software. For the Linux system, the software only controls the CPU operating frequency by monitoring the CPU utilization. When the system finds that the CPU utilization rate increases, it sets a higher operating frequency for the CPU according to established rules, and sets a lower operating frequency when the CPU utilization rate decreases. This method is applicable to most situations, but it has limitations for edge computing nodes that handle bursty large concurrent tasks. It is mainly manifested in that for busin...

Embodiment

[0081] The purpose of the present invention is to provide a method for adjusting the CPU operating frequency of an edge computing node, so that the edge computing node can process sudden tasks in a timely manner, and at the same time reduce power consumption when there is no task.

[0082] image 3 Describes the relationship between IoT devices, edge computing nodes, and cloud computing nodes.

[0083] IoT devices use their own sensors to gather useful information about where they are located. Send information to edge computing nodes through the network. The edge computing node uses its own computing power to perform preliminary processing on the collected information. Processing collected information first at edge computing nodes can effectively reduce the amount of data transmitted to cloud computing nodes, reduce transmission costs, and ensure data security. At the same time, it can improve the response speed to key information, so as to discover and deal with it in time...

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a CPU frequency adjustment method, system, device and storage medium of an edge computing node. Background technique [0002] In traditional power computing, the data collected by each power terminal will be transmitted to the master station for centralized processing. In the ubiquitous power Internet of Things, various growing power terminal equipment and business applications will generate massive amounts of data. The transmission and processing of these data will put enormous pressure on the main station, and the high delay and security cannot meet the requirements of new technologies. business form requirements. [0003] Edge computing, on the other hand, provides services on the nearby user side to meet the business requirements of real-time data analysis and processing and low latency, while ensuring data security and helping power grids avoid risks. Based on th...
