Problems solved by technology

In terms of experimental content, traditional experiments focus on using an oscilloscope to adjust the waveform. When adjusting the measurement distance, it is necessary to shake the handwheel to move the ultrasonic sensor, which adds many links to the experimental measurement itself and errors caused by manual movement; and the experimental equipment has a single function. Occupies a large area and cannot meet the teaching requirements

Embodiment 1

[0034] Such as figure 1 and 2 As shown, an ultrasonic experimental equipment with multiple detection functions, which includes a box (or box) 1, an operation panel 12, a controller 5, an ultrasonic sensor 4, an obstacle plate 6, a guide rail transmission mechanism, and is used to display ultrasonic waves. The first display module 10 of the distance measurement value, the second display module 13 and the AD module 7 for displaying the round-trip time value of the ultrasonic wave from transmission to reception;

[0035] The first display module 10, the second display module 13, the controller 5, and the AD module 7 are embedded on the operation panel 12, and the operation panel 12 is installed on the box body 1;

[0036] The ultrasonic sensor 4 is installed on the sensor bracket 3, the sensor bracket 3 is installed on the first slider 2, the first slider 2 is slidably installed on the first guide rail 2-1, and the first guide rail 2-1 is fixed on the operation panel 12 on;

...

Embodiment 2

[0052] Such as Figure 4 As shown, the difference between the second embodiment and the first embodiment is that the sensor bracket 3 in the first embodiment has three rotational degrees of freedom adjustment functions, and the sensor bracket 3 includes a bracket 3-1 for fixing the ultrasonic probe, a first steering gear 3-2, the first U-shaped frame 3-3, the second steering gear 3-4, the second U-shaped frame 3-5, and the turntable 3-6 driven by the third steering gear, the support 3-1 passes through The steering gear plate is fixed on the first steering gear 3-2 (the bracket 3-1 is tightly connected with the steering gear plate by screws, and the steering gear plate is tightly connected with the first steering gear 3-2 by screws), and the first steering gear 3-2 is installed on the first U-shaped frame 3-3, the first U-shaped frame 3-3 is tightly connected with the second steering gear 3-4, and the second steering gear 3-4 is installed on the second U-shaped frame 3 -5, the...

Embodiment 3

[0056] On the basis of the first embodiment, the operation panel 12 is also provided with a DA module, see the attached Image 6 , the output terminal of the controller is connected to the DA module, and the DA module has an output line for connecting to an oscilloscope;

[0057] The output line of the DA module is connected to the oscilloscope. The controller converts the received digital signal of the ultrasonic sensor into an analog signal through the DA module and outputs it to the oscilloscope. The waveform experiment of observing the feedback signal of the ultrasonic sensor is carried out through the oscilloscope.

Abstract

The present invention discloses an ultrasonic experimental apparatus with multiple detection functions. The operation panel of the apparatus is provided with an ultrasonic sensor, an obstacle plate, a rail transmission mechanism, a first display module for displaying an ultrasonic distance measurement value, a second display module for displaying a round trip time value of the ultrasonic wave from emission to reception, an AD module and a DA module. The ultrasonic sensor is mounted on a sensor support which is mounted on a first slide block, the first slide block is mounted on a first guide rail, and the first guide rail is fixed on the operation panel. The obstacle plate is arranged on the rail transmission mechanism. The ultrasonic experimental apparatus is used to perform the speed measurement experiment, the object flatness test, and the ultrasonic sensor feedback signal waveform observation test.

Description

technical field [0001] The invention belongs to the technical field of teaching experiment equipment, and in particular relates to an ultrasonic experiment equipment with multiple detection functions. Background technique [0002] Due to the wide application of ultrasound in the fields of industry and scientific research, it is particularly important to apply ultrasound to the teaching of basic courses in physical experiments. In terms of experimental content, traditional experiments focus on using an oscilloscope to adjust the waveform. When adjusting the measurement distance, it is necessary to shake the handwheel to move the ultrasonic sensor, which adds many links to the experimental measurement itself and errors caused by manual movement; and the experimental equipment has a single function. Occupies a large area, can not meet the teaching requirements. Contents of the invention [0003] The purpose of the present invention is to overcome the limitations of the exist...
