Embodiment Construction

[0026] In the following description, numerous details are provided in order to provide a thorough understanding of the invention. However, it will be appreciated by those skilled in the art that the following description relates only to preferred embodiments of the invention and that the invention may be practiced without one or more of these details. In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0027] According to one aspect of the present invention, an ultrasonic height measuring device is provided. The device uses ultrasound to measure a person's height. However, the propagation speed of ultrasonic waves is affected by the ambient temperature. At room temperature, the propagation speed of ultrasonic waves is about 340m / s. Generally, every time the temperature rises by 1 degree Celsius, the ultrasonic propagation speed increases by about 0.6m / s. The relationship between the ultrasonic p...

Abstract

The invention provides ultrasonic body height measuring equipment. The ultrasonic body height measuring equipment comprises an equipment main body, a plurality of temperature sensors and a body height measuring device, wherein the plurality of temperature sensors are arranged at different heights of the equipment main body and used for sensing the temperature on an ultrasonic propagation path and generating a temperature electric signal according to the sensed temperature; the body height measuring device is at least partly arranged at the top part of the equipment main body, electrically connected with the temperature sensors and used for measuring ultrasonic propagation parameters and acquiring a body height measurement value compensated by the temperature according to the temperature electric signal and the ultrasonic propagation parameters. The ultrasonic body height measuring equipment is capable of accurately calibrating the velocity of ultrasonic waves and reducing errors of body height measurement caused by environmental temperature, and thus accurate body height measurement results are obtained.

Description

technical field [0001] The invention relates to the research field of measuring instruments and equipment, in particular to an ultrasonic height measuring equipment. Background technique [0002] The Ultrasonic Height Meter uses ultrasonic distance measurement technology to measure height. It belongs to non-contact measurement, clean and hygienic, and rapid measurement. At present, this ultrasonic measuring instrument has been widely used in places with a large number of users such as medical examination centers and hospital medical examination departments. However, the existing ultrasonic height measuring instrument is affected by the ambient temperature, and the height measurement accuracy is relatively poor, and its measurement accuracy is generally questioned by people. [0003] Existing ultrasonic height measuring instruments generally adopt a single temperature compensation method. This method only measures temperature values ​​at a certain altitude. When the tempe...
