Problems solved by technology

[0003] However, the speed of ultrasonic waves in the air varies according to the ambient temperature. If the influence of temperature on the propagation speed of ultrasonic waves is not excluded, it will cause errors in distance measurement. Therefore, it is necessary to comprehensively consider the temperature of ultrasonic distance measurement and ultrasonic propagation. Design Portable distance meter, providing convenience for production and life

Abstract

The invention provides an ultrasonic voice distance measuring instrument which comprises a main control MCU (Micro Control Unit) module, an ultrasonic transmission and receiving module, a temperature measurement module, a liquid crystal display control module and a voice reporting module. The distance measuring instrument which is high in precision, good in portability and convenient to operate is provided by comprehensive consideration of possible errors of ultrasonic distance measuring and rational design of the instrument. According to the instrument, a measuring result is subjected to liquid crystal display and reported in real time by the voice module; the measuring precision is improved by comprehensive consideration of influence of temperature on the ultrasonic distance measuring; and in addition, the instrument has an over-limit alarm function, has the advantages of simplicity in operation and stable in performance and has a good use value.

Description

technical field [0001] The invention relates to the field of instruments and meters, in particular to an ultrasonic voice range finder. Background technique [0002] Ultrasound has strong directivity, slow energy consumption, and a long distance in the medium. Therefore, ultrasonic waves are often used to measure distances. Ultrasonic waves are emitted in a certain direction through an ultrasonic transmitter, and timing starts at the same time as the emission. Ultrasonic waves propagate in the air. When encountering an obstacle on the way, it will return immediately, and the propagation distance can be calculated according to the propagation speed and propagation time of the ultrasonic wave in the air. This is the so-called time difference ranging method. [0003] However, the speed of ultrasonic waves in the air varies according to the ambient temperature. If the influence of temperature on the propagation speed of ultrasonic waves is not excluded, it will cause errors in d...
