Energy distribution method and system based on maintaining state in nonvolatile processor

Abstract

The invention relates to an energy distribution method and an energy distribution system based on a maintaining state in a nonvolatile processor. The energy distribution method comprises the steps ofbuilding an energy distribution model according to available energy stored in a capacitor after a system is powered down; acquiring system energy recovering time according to sampled data of the environment energy; working out a path between an energy break point to the furthest point where a command can be executed according to the available energy; screening out a node of which the sum of continuous executing energy and backup energy is less than the available energy stored in the system capacitor to serve as an available backup point, and working out maintenance time and continuous executing time according to the energy distribution model; comparing the sum of the maintenance time and the continuous executing time with the system energy recovering time, if the sum is more than the system energy recovering time, performing data maintenance, and if the sum is less than the system energy recovering time, computing earnings of the available backup point in the case of performing data maintenance and in the case of directly backing up without maintenance and comparing the earnings, and performing data maintenance or data backup according to a comparison result.

Description

technical field [0001] The invention belongs to the technical field of energy distribution, and in particular relates to an energy distribution method and system based on maintaining state in a non-volatile processor. Background technique [0002] With the rapid development of the Internet of Things, wearable devices such as smart bracelets and smart watches have been widely used. Most wearable devices can detect physiological data such as heart rate, body temperature and breathing rate of the user in real time. Typically, wearable devices are powered by an equipped rechargeable battery. Rechargeable batteries have the problem of requiring frequent recharging, and their bulky rechargeable batteries are not suitable for medical wearables. [0003] In order to solve the power supply problem of medical wearable devices, people also use the energy harvesting system to convert the energy of the surrounding environment such as solar energy, wind energy and human body temperature...
