| With the increase and popularization of cloud computing and Internet of Things devices,energy has increasingly become the main bottleneck restricting the development of information technology.The concept of the integrated operating system for energy information is proposed.Energy is similar to the consumption of computers such as memory and processor occupancy rate,and should be scheduled like other resources.Realizing this vision requires two efforts,energy demand with related scheduling and energy acquisition technology.The main work of this paper is as follows: In terms of energy demand analysis,this paper first analyzes the principles of computer system energy consumption,and classifies and introduces the load tasks faced by computers.Then summarized and investigated several mainstream mathematical models of computer energy consumption.For neural network and linear model,basic modeling and test comparison are carried out on the simulation program.In addition,this article summarizes several different aspects of scheduling algorithms related to computer energy consumption,and conducts simulation scheduling experiments under unstable environmental energy.In terms of energy acquisition,environmental energy harvesting technology is an effective technology to resolve the conflict between energy consumption and performance of Io T devices.Multi-source environmental energy harvesting technology can further increase the stability and availability of environmental energy harvesting.When multiple sources work at the same time,how to make different energy sources with huge performance differences work together while reducing energy loss as much as possible is an important challenge.This paper establishes a multi-source environment energy harvesting model.We conducted experimental verification on the energy interface built in the design,and recorded the output properties of different environmental energy sources such as wind,light,and heat when working alone;and tested the interface loss when the energy sources work together.Experimental data shows that the interface loss of multi-source environmental energy harvesting is often less than one percent compared with that of environmental energy sources working alone. |
