Embodiment 1

[0028] Such as Figure 1-4 shown.

[0029] A height and weight monitoring device based on biometric identification, including a weight measuring part and a height measuring part, and the weight measuring part includes a pedal 1, a pressure bar 3, a pressure sensor 2 and a base 4 arranged from top to bottom , a boss 8 is provided on the rear side edge of the pedal 1; a height measuring part is provided on the front side edge of the pedal 1, and the height measuring part includes a fixed rod fixedly connected with the pedal 9. A height test rod 12 that is axially movably connected on the fixed rod 9, a display screen 10 is arranged on the fixed rod 9, an ultrasonic sensor 11 and a microphone 14 are arranged on the height test rod 12, and the The top of the height test rod 12 is provided with a camera 13; in the base 4, a control unit 6 is installed, and the control unit includes a connected single-chip microcomputer and memory, the camera 13, display screen 10, pressure sensor ...

Embodiment 2

[0032] Such as Figure 5 shown.

[0033] A working method of height and weight monitoring device as described in embodiment 1, comprising steps as follows:

[0034] (1) Turn on the monitoring device;

[0035] (2) The person to be measured stands on the pedal 1 of the monitoring device, and the heel of the person to be measured is flush with the boss 8;

[0036] (3) The camera 13 is automatically adjusted by an ultrasonic sensor, and the camera 13 is aligned with the face of the person to be measured, so that the face area completely falls into the viewing range of the camera, and the face image is collected;

[0037] (4) Use the face recognition software in the control unit to compare the collected face image with the face image data in the memory: if the current face image data does not exist in the memory, the control unit controls the speaker inquiry mode Or ask the name of the person to be measured by displaying on the display screen, and the person to be measured enter...

Abstract

The invention relates to a height and weight monitoring device based on biometric feature recognition. The height and weight monitoring device comprises a weight measurement part and a height measurement part, wherein the weight measurement part comprises a pedal, a compression bar, a pressure sensor and a base, wherein the pedal, the compression bar, the pressure sensor and the base are arranged from top to bottom; a boss is arranged at the edge of the rear side of the pedal; the height measurement part is arranged at the edge of the front side of the pedal; the height measurement part comprises a fixing bar and a height measurement bar, the fixing bar is fixedly connected with the pedal, the height measurement bar is axially movably connected to the fixing bar, and a display screen is arranged on the fixing bar; an ultrasonic sensor and a microphone are arranged on the height measurement bar, and a camera is arranged at the top end of height measurement bar. By the adoption of the height and weight monitoring device, information of people can be recognized, a human health database is established, manual input of data of people is avoided, labor intensity of operation is reduced, subjective errors in the manual reading process are reduced, and human-computer interaction can be conducted.

Description

technical field [0001] The invention relates to a height and weight monitoring device and working method based on biometric feature identification, and belongs to the technical field of electronic measuring instruments. Background technique [0002] With the development of modern life and economy, people pay more and more attention to their own health problems, so many instruments for measuring human health have great market prospects. At present, there are many health scales that can calculate the human health index on the market. Most of its working modes are manual input of height and measurements, combined with the weighing function of the body scale itself, to calculate the user's health index, such as BMI, BMR and Body Fat. However, these health care scales need to manually input various human body data parameters, remember a previous weight and calculate health indicators and display them on the display screen, so the input cycle is long and the use is very cumbersom...
