Embodiment Construction

[0030] The present invention will be further described below:

[0031] A method for accurately detecting the amount of drinking water in a water cup, comprising the following steps:

[0032] A1: Use the pressure sensor to weigh the water in the water cup and get the original mass m1 of the water;

[0033] A2: Obtain the original water volume L in the cup by multiplying the original mass m1 of the water by the water density, and calculate the original height h of the water in the cup according to the volume characteristics of the cup;

[0034] A3: According to the volume characteristics of the water cup, calculate the critical inclination angle φ of the water cup when the water is poured out of the water cup;

[0035] A4: Set the inclination angle of the water cup when drinking water in the cup to φ1, and the inclination angle φ1 is a variable that is constantly changing when drinking water. Measure the inclination angle φ1 of the water cup and the rate of change of the inclin...

Abstract

The invention discloses a method for accurately detecting drinking water volume of a cup. The method comprises the steps that whether the cup is located in a water pouring state or in a water drinking state is measured and determined through a 3D acceleration sensor, the original water volume in the cup and the surplus water volume in the cup after water is drunk are measured through a pressure sensor, and the accurate drinking water volume is obtained through a comprehensive measurement structure. According to the method, the mode of establishment of a mathematical model is adopted, accurate calculation of the drinking water volume of the cup is achieved on the premise that more hardware sensing devices are not added, the cup can be weighed when the cup is held up, a user adds water to the cup after the user drinks water, and drinking water drunk by the user can also be accurately recorded.

Description

technical field [0001] The invention relates to the technical field of smart water cups, in particular to a method for accurately detecting the amount of drinking water in a water cup. Background technique [0002] At present, there are two main methods for detecting the amount of drinking water in a water cup: the first method is to use a pressure sensor combined with a 3D acceleration sensor to judge the amount of drinking water; the second method is to use a capacitive sensor combined with a 3D acceleration sensor to judge the amount of drinking water. [0003] In the first method, the pressure sensor is used to measure the weight of the water in the cup, and the 3D acceleration sensor is used to judge the movement direction and acceleration of the cup. When the volume of water in the cup decreases, combined with the 3D acceleration sensor to identify that the water is drunk, the first weighing weight minus the second weighing weight is used to count the drinking water; o...
