Problems solved by technology

[0002] In the prior art, the distance measurement of the parking position is usually measured by an ultrasonic probe. Aftershocks will be generated during the ultrasonic distance measurement process. Longer aftershocks will result in a larger range of the minimum ultrasonic measurement distance, and the distance measurement accuracy of the parking position is relatively low. Low

Embodiment Construction

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

[0026] With the development of the city, the urban space is getting smaller and smaller, and the parking space is getting smaller and smaller. Whether it is automatic parking or manual parking, it is necessary to measure the distance very accurately. Now the most mature and effective distance measurement system is to use The ultrasonic probe is used for ...

Abstract

The invention provides an ultrasonic aftershock reduction device and method, and ultrasonic detection equipment, and relates to the technical field of ultrasonic detection.The method comprises the steps that firstly, a controller controls a current generation module to generate a current signal matched with oscillation parameters based on the oscillation parameters, obtained in advance, of oscillation signals of an ultrasonic probe, wherein the direction of the current signal generated by the current output module is opposite to that of the current signal causing oscillation of the ultrasonic probe; then the current induction module generates an induction current signal based on a preset current signal generated by the current generation module; and the induction current signal acts on the ultrasonic probe so as to counteract an oscillation signal of the ultrasonic probe. According to the mode, aftershock generated by the ultrasonic probe is reduced, so that the accuracy of distance measurement based on the ultrasonic probe is improved.

Description

technical field [0001] The invention relates to the field of ultrasonic technology, in particular to an ultrasonic aftershock reduction device, method and ultrasonic detection equipment. Background technique [0002] In the prior art, the distance measurement of the parking position is usually measured by an ultrasonic probe. Aftershocks will be generated during the ultrasonic distance measurement process. Longer aftershocks will result in a larger range of the minimum ultrasonic measurement distance, and the distance measurement accuracy of the parking position is relatively low. Low. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide an ultrasonic aftershock reduction device, method and ultrasonic detection equipment to reduce the aftershock generated by the ultrasonic probe, thereby improving the accuracy of distance measurement based on the ultrasonic probe. [0004] In the first aspect, an embodiment of the present ...
