Body fat scale capable of automatic awakening

Abstract

The invention discloses an intelligent body fat scale which has a main body which has a MCU unit, a sensor unit, a signal processing unit, a data storage unit and a wireless data transmission unit. The sensor unit acquires weight and body fat data of a user, transmits the acquired information to a signal processing unit, processes the information, and saves the information to the data storage unit. At the same time, the data is transmitted to an intelligent device in wireless transmission. If the sensor unit of the body fat scale, after the user completes scaling, does not detect a signal, the MCU unit determines that the intelligent scale is available, and transmits a command, such that the intelligent scale enters a standby state. When the intelligent scale is at the standby status, the intelligent scale does not display information and only consumes minimum power to enable a CPU to work. When the user stands on the intelligent scale, the sensor of the intelligent scale detects pressure which causes the sensor to deform, and the sensor unit immediately transmits a signal to the signal processing unit. At that time, the MCU unit determines that the intelligent scale is occupied by the user, sends a command, and the MCU unit is awakened and enters the scale awaiting status.

Description

technical field [0001] The invention relates to the technical field of intelligent body fat scales, in particular to a body fat scale with an automatic wake-up function. Background technique [0002] In terms of nutrition and health, body weight is a very important indicator, and the scale is a classification in the function of weighing instruments, which is used to accurately measure the body's weight and reflect a certain period of time through daily body weight changes Therefore, weight control is the basis of health management. Body weight is an objective indicator reflecting whether the dietary intake (energy intake) is appropriate. Weight changes (increase or decrease) reflect the recent balance between diet and exercise. Significant reduction or rapid increase is often the manifestation of disease. Body weight (is an objective indicator to measure children's growth and feeding (nutrition) status. Maintaining normal weight growth is the key to guiding pregnant women's ...

AI Technical Summary

Problems solved by technology

[0004] Weighing on the above-mentioned weighing scale is a short-term process, and its operation time is completed within one minute, and the smart scale is a device that needs to be used frequently. If the power switch is set, the user needs to turn on the switch before each weighing If the scale is not equipped with a power switch, the smart scale will be turned on at any time, and the smart scale that is turned on at any time is also in working state when not in use, which will cause the battery of the smart scale to be consumed too quickly
