Method and device for measuring volume of liquid in container based on acceleration sensor

Abstract

The invention discloses a method and device for measuring volume of liquid in container based on an acceleration sensor. According to the scheme of the method and device, the acceleration sensor is utilized for obtaining different attitude parameters, and through the attitude parameter obtained when the container stably reaches the water outlet critical position, the volume of the liquid which is contained in the container at present is calculated by utilizing the mapping relation between the pre-determined attitude parameter and the liquid volume or the water volume. The method and device have the advantages of being extremely great in universality, low in power consumption, low in cost, low in structural requirement and the like.

Description

technical field [0001] The invention belongs to the field of intelligent equipment, and relates to a method and device for measuring the volume of liquid in a container, in particular to a method and device for measuring the volume of liquid in a container based on an acceleration sensor. Background technique [0002] As the source of life, water is an essential substance for people's survival. The correct way of drinking water helps people to maintain health. However, in the past, people only relied on their own feelings to drink water and could not intuitively understand their water intake. With the enhancement of awareness and the advancement of technology, smart drinking water equipment has begun to be welcomed by people. It can accurately measure the amount of water people consume in a day, so that people can rationally plan their own water consumption. At the same time, the drinking water data will become the whole big health data. an important part of. However, in th...

[0002] As the source of life, water is an essential substance for people to survive. The correct way of drinking water helps people maintain health. However, in the past, people only relied on their own feelings to drink water, and could not intuitively understand their drinking water. As people's health With the enhancement of awareness and the advancement of technology, smart drinking water equipment has begun to be welcomed by people. It can accurately measure the amount of water people consume in a day, so that people can plan their drinking water reasonably. At the same time, the drinking water data will become the whole big health data. an important part of

However, in the field of smart water cups, flow meters, capacitance methods, ultrasonic waves, weighing methods, etc. are usually used to measure the amount of water. However, these methods are not universal, and they can only work normally in specific application scenarios.
