The principle of ultrasonic height and weight measuring instrument
Release Time:
2020-05-23
Ultrasonic Height and Weight Examination Machine Ultrasonic Principle:
It adopts microcomputer control and advanced ultrasonic measurement technology to automatically measure height and weight. The measurement results are displayed on an LCD screen and announced verbally.
Technical Features of the Ultrasonic Examination Machine:
This machine is an ideal choice for hospitals, pharmacies, clinics, schools, kindergartens, supermarkets, public security, military systems, fitness centers, physical examination centers, leisure facilities, community public health, and government agencies. Ideal Choice.
The ultrasonic measuring instrument uses ultrasound as a detection method and must generate and receive ultrasonic waves. The sensor determines the height of the human body through the wavelength of the sound wave and the time difference between emitting and receiving the sound wave. While sending the pulse, the receiver's timer starts and times until the receiving sensor receives the reflected wave, the counting stops, and this time difference is equivalent to the measured distance, so the distance between the measuring instrument and the top of the head, i.e., the height of the person, can be calculated.
Design Concept of the Ultrasonic Examination Machine:
A basic ultrasonic measuring instrument has two sub-modules: distance measurement and data display. The data display module consists of three parts: counting, display, and signal processing.
The measurement is mainly completed by the ultrasonic sensor. The time difference between emission and reception is converted into an electrical signal, then an A/D converter obtains a digital signal, which is then sent to the calculation part and then to the display.
System Composition of the Ultrasonic Examination Machine:
The ultrasonic height measuring instrument consists of a single-chip microcomputer central control system, an ultrasonic transmitting circuit, and an ultrasonic receiving circuit. The ultrasonic transmitting circuit consists of a transmitting driving circuit and an ultrasonic transducer located at the output end of the driving circuit. The ultrasonic receiving circuit consists of an ultrasonic receiving transducer, a limiting circuit, and an ultrasonic receiving integrated circuit.
Ultrasonic sensors are sensors developed using the characteristics of ultrasonic waves. Using ultrasound as a detection method, it is necessary to generate and receive ultrasound. The device that performs this function is the ultrasonic sensor. Ultrasonic sensors are mainly composed of piezoelectric wafers and can both transmit and receive ultrasonic waves.
Main Parameters of the Basic Ultrasonic Height and Weight Examination Machine:

With the improvement of living standards, more and more people pay attention to health, and health checkups have become a necessity of life. Ultrasonic height and weight measuring instruments, in response to the development of the times, have expanded on the original basis to include some commonly used health checkup items. For example, the Shengyuan brand 800A ultrasonic height and weight scale adds some health checkup items such as fat and blood pressure measurement on the basis of height and weight measurement. Voice prompts guide the measurement items and steps to make self-service checkups easier, and a measurement receipt is printed for easy reference.
