A method and system for dynamic power consumption control of industrial terminals based on load prediction

Abstract

This invention provides a method and system for dynamic power consumption control of industrial terminals based on load prediction. The method includes: determining idle time periods based on the execution time information of each task in the task queue of the industrial terminal; if no tasks are being executed, determining candidate power-off power domains based on the target functional modules dependent on the last task before the idle time period and the first task after the idle time period, combined with the affiliation relationship between functional modules and power domains; performing islanding region analysis based on the electrical relationships between candidate power-off power domains to obtain target power-off power domains, and generating a power-off strategy for each target power-off power domain based on the duration of the idle time period and the recovery energy cost of each target power-off power domain; controlling the corresponding target power-off power domain to enter a power-off state based on the power-off strategy of each target power-off power domain, and maintaining its power-off state during the duration of the idle time period. This invention achieves fine-grained control of power consumption of industrial terminals.
