Abstract

The invention relates to an ultrasonic distance measuring system, in particular to an ultrasonic distance measuring instrument capable of realizing voice broadcast for determining the measured distance through detecting the travel time of ultrasonic waves at the detected distance in different environments. The ultrasonic distance measuring instrument is characterized by comprising a core control unit 11, an ultrasonic module 15, a display module 14, a voice broadcast module 12 and a power supply module 13, wherein the core control unit 11 is used for controlling and coordinating the work of each module, is in charge of processing and calculating the data measured by the ultrasonic wave receiving module and transmits measuring results to an output module, the ultrasonic wave module 15 can generate measuring sound waves and can receive the reflected ultrasonic waves, the display module 14 adopts a digital tube for displaying the measuring results, the voice broadcast module 12 adopts a Chinese voice synthesis chip for synthesizing the measuring results into the Chinese voice to be broadcasted, and the power supply module 13 comprises a battery, a corresponding battery protection circuit and a charging circuit, and supplies electricity to the whole system. Through the application of the system, the work efficiency of the engineering distance measurement can be effectively improved, the requirements of daily life and practical production can be met, and certain practical and popularization values are realized.

Description

technical field [0001] The invention relates to an ultrasonic distance measuring system, in particular to an ultrasonic distance measuring instrument with a voice broadcast function which can determine the measured distance by detecting the propagation time of the ultrasonic wave on the detected distance in different environments. Background technique [0002] At present, ultrasonic range finders are widely used in many fields, such as engineering distance measurement, reversing radar, etc., but many range finders can only display measurement results, which is not very convenient to use. The invention proposes a ranging system with simple structure, simple design, modular structure, accurate, convenient and safe detection, and uses a voice broadcast system to make it possible to broadcast the measurement data in time, so that the measurer is more intuitive to obtain data. The system is less subject to external interference, high integration, small size, moderate cost, and c...
