Problems solved by technology

However, the premise of this type of ultrasonic measurement is that there must be an obstacle in front to form the sound wave reflection. When there is no obstacle in front, the distance measurement cannot be carried out, which has certain limitations.
Moreover, even if ultrasonic waves are used for reflection distance measurement, the requirements for the emission echo surface are relatively high, the reflection angle cannot be too large, and echo interference cannot be formed, otherwise it will cause inability to measure or large errors

Abstract

The invention discloses a split type ultrasonic precise distance measuring device. The device comprises a signal distance measuring device transmitting terminal and a receiving terminal, wherein the transmitting terminal comprises an input / output pin (1), a transmitting terminal central processing chip (3), an infrared transmitting tube (2) and an ultrasonic transmitting probe (4), the transmitting terminal central processing chip (3) controls the infrared transmitting tube (2) and the ultrasonic transmitting probe (4) to transmit signals simultaneously. The receiving terminal comprises a receiving terminal central processing chip (6), an ultrasonic receiving probe (5), a receiving terminal ultrasonic signal processing chip (7), an infrared receiving tube (8) and a signal input / output pin(9), data of the receiving end ultrasonic signal processing chip (7) and the infrared receiving tube (8) are processed by the receiving terminal central processing chip (6) and output by the signal input / output pin (9). The device avoids the limitation of measurement through barrier reflection during traditional distance measurement and has the advantages of being low in cost, easy to operate, precise in measurement and the like.

Description

technical field [0001] The invention relates to the field of ultrasonic waves, in particular to an improvement of an ultrasonic distance measuring method. Background technique [0002] Ultrasound propagates at different speeds in gases, liquids and solids. It has the advantages of good orientation, concentrated energy, small attenuation during transmission, and strong reflection ability. It is often used to measure distances. Utilizing the directional transmission of ultrasonic waves, the characteristics of reflection formed after encountering obstacles, the actual distance can be calculated by measuring the round-trip time of ultrasonic waves and multiplying by the actual propagation speed, so as to realize the non-contact measurement of the target distance. Ultrasonic rangefinders are mainly used in scenarios such as reversing reminders, construction sites, and industrial sites. However, the premise of this type of ultrasonic measurement is that there must be an obstacle ...
