AI Technical Summary

Technical Problem

Existing medical height and weight scales have significant measurement errors when measuring height because infrared or ultrasonic measurements are easily obstructed by hair.

Method used

The medical height and weight integrated scale uses QR code recognition and intelligent measurement. It features a movable pressure plate and a rangefinder. The pressure plate presses firmly against the top of the person being measured to cooperate with the rangefinder for height measurement, avoiding hair obstruction. The pressure plate is driven by a servo motor and ball screw to ensure measurement accuracy.

Benefits of technology

It effectively reduces the error in height measurement, making the measurement more accurate and improving the precision and efficiency of measurement. Furthermore, through QR code recognition and intelligent control, it simplifies the data entry and transmission process.

Abstract

This utility model discloses a medical height and weight integrated scale based on QR code recognition and intelligent measurement. The medical height and weight integrated scale includes: a weight scale and a column, the column extending vertically and connected at its lower end to the weight scale; a mounting base connected to the upper end of the column; and a height measuring component, including a pressure plate and a distance measuring device. The distance measuring device is mounted on the mounting base, the pressure plate is horizontally arranged, and the pressure plate is movably positioned on the column in the vertical direction. The pressure plate is located below the distance measuring device, and the distance measuring device is configured to measure the vertical distance between the distance measuring device and the pressure plate when the pressure plate is pressed against the head, thereby obtaining the height of the person being measured. According to this utility model, when measuring height, the pressure plate can press against the top of the person being measured to cooperate with the distance measuring device for height measurement, avoiding the influence of hair obstructing the measurement, thus reducing the height measurement error and making the measurement more accurate.
