Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings.

[0034] refer to Figure 1 ~ Figure 4 , a user identification method suitable for household weighing scales, the household weighing scale is provided with a pressure sensor and a foot length sensor for detecting the length of the user's feet, and the identification method includes the following steps:

[0035] 1) The user steps on the household weight scale, obtains the weight value according to the pressure sensor, and obtains the foot length value according to the foot length sensor;

[0036] 2) Calculate the matching degree p between the current user h and the maintained user i ,

[0037] p i =f(|W h -W i |-3)×f(|F h -F i |-1)×(|W h -W i | 2 +ρ)

[0038] Among them, W h is the current user weight value, F h It is the current user's foot length value; set the saved user as i=0,1,2,...n, and the latest weight data of the i-th saved user is W i , the lates...

Abstract

The invention discloses a user identity identification method applicable to a household weighing scale. A pressure sensor and a foot length sensor are arranged on the household weighing scale, wherein the foot length sensor is used for detecting the length of the feet of a user. The user identity identification method comprises the following steps of: (1) when the user steps on the household weighing scale, acquiring a weight value according to the pressure sensor, and acquiring a foot length value according to the foot length sensor; (2) calculating a matching degree pi between the current user h and stored users; (3) if the data of one or more stored users in the stored users are matched with the data of the current user, sorting the users according to the size of the pi, and selecting one of the stored users as the current user identity. By the adoption of the user identity identification method applicable to the household weighing scale, provided by the invention, the user identity identification is effectively realized, and data archiving and statistics can be facilitated.

Description

technical field [0001] The invention relates to the field of weighing scales, in particular to a user identification method for household weighing scales. Background technique [0002] Body weight is one of the most important indicators of health. Scientific investigations have shown that overweight people often have high body fat content and are prone to cardiovascular diseases; while underweight people are prone to low immunity and disease The probability of infectious diseases will increase. At the same time, changes in body weight over a period of time may also be a disease alarm issued by the human body. With the accelerated pace of life, more and more people ignore their own health concerns, so that they cannot be detected and treated as early as possible. Therefore, how to design an intelligent and convenient health monitoring system is very meaningful. [0003] Traditional weighing scales often only have the function of displaying the current user's body mass inde...
