High-precision height-measuring device based on ultrasonic

Abstract

The invention relates to a high-precision height-measuring device based on ultrasonic. The device comprises an ultrasonic emitting module, an ultrasonic emitting driving circuit, an ultrasonic data acquiring module, a band-pass filtering circuit, an ARM processor, an LCD (liquid crystal display) detection display, an EEPROM (electrically erasable programmable read-only memory) memory, a voice broadcasting circuit and a power module; and the modules are respectively connected with the ARM processor in order to realize distributed control, the power module is used for supplying power for the ARM processor, an emitting system of an ultrasonic signal is composed of the ultrasonic emitting module and the ultrasonic emitting driving circuit, a receiving and filtering system of the ultrasonic signal is composed of the ultrasonic data acquiring module and the band-pass filtering circuit, and a height data display, storing and broadcasting system is composed of the LCD detection display, the EEPROM memory and the voice broadcasting circuit. The high-precision height-measuring device based on ultrasonic provided by the invention is high in speed, the height data can be clearly displayed on the LCD screen and broadcasted through the voice, and the device is a high-tech, intelligent and automatic novel device.

Description

[0001] technical field [0002] The invention relates to the field of intelligent and automatic distance measurement, in particular to a high-precision height measurement device based on ultrasonic waves. [0003] Background technique [0004] At present, the methods and standards for the height test of primary and middle school students are not uniform, and the measuring equipment is backward. The standardization, scientization and standardization of the national regulations have always been a problem for various schools. At present, most of the domestic equipment is realized by manual measurement and mechanical structure, which has defects such as slow speed and large noise, and there is no anti-interference filter, resulting in particularly large data errors. [0005] Therefore, in order to avoid the above-mentioned technical problems, it is necessary to provide a high-precision height measuring device based on ultrasound to overcome the defects in the prior art.
