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.
