Abstract

The invention discloses a circuit applied to sound intensity measurement of ultrasonic waves. The circuit applied to sound intensity measurement of the ultrasonic waves comprises a power supply management module, a signal processing module, a communication module, a control module, an input and output module and a communication module. The power supply management module comprises a 3.3V voltage switching circuit with AMS1117-3.3 as a core, the communication module is composed of RS232 connectors, the signal processing module is mainly composed of a voltage amplifier LM358 and a voltage comparator LM393ADR, the input and output module is mainly composed of a Nokia 5110 liquid crystal display and keys, and the control module is mainly composed of STC12C5628AD. The circuit applied to sound intensity measurement of the ultrasonic waves is small in size, capable of being made into a handheld type circuit, convenient to carry along and easy to operate. Batteries are utilized for providing electricity, power consumption is low and precision is high, and the functions of signal process, data process and output and the like are achieved.

Description

technical field [0001] The invention belongs to the technical field of industrial measurement, and in particular relates to a circuit applied to ultrasonic sound intensity measurement. Background technique [0002] With the development of modern industry, the ultrasonic effect has been widely used in practice, and the sound intensity (sound power) is one of the most important indicators of the ultrasonic system. It has a direct impact on the use effect and work efficiency of ultrasonic equipment. More and more industrial sites need to measure the sound intensity of ultrasonic waves. Large and bulky, it is not suitable for carrying around, and it is difficult to meet the measurement requirements of modern industrial sites. Contents of the invention [0003] The present invention proposes a circuit for ultrasonic sound intensity measurement in view of the large power consumption, relatively low precision and unsuitability for on-site use of the current sound intensity m...
