Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0033] Such as figure 1 As shown, according to the logic type ultrasonic probe array system and method based on comparison and gating provided by the present invention, the system mainly includes an ultrasonic instrument, an ultrasonic probe array, a gating control array and a comparator array, wherein, when the ultrasonic instrument sends an ultrasonic probe After the array sends out the initial excitation pulse, the ultrasonic probe array receives the ultrasonic echo signals of each channel. Since ea...

Abstract

The invention provides a logic type ultrasonic probe array system and method based on comparison and gating, the system comprises an ultrasonic instrument, an ultrasonic probe array, a gating control array and a comparator array; the ultrasonic instrument sends an initial excitation pulse to the ultrasonic probe array; the ultrasonic probe array receives an ultrasonic echo signal of each channel; the comparator array compares a plurality of ultrasonic echo signals received by the ultrasonic probe array to obtain the serial number of the ultrasonic echo signal with the maximum amplitude, and controls the gating logic array through the serial number; and the gating control array receives the plurality of ultrasonic echo signals, opens the ultrasonic echo signals corresponding to the serial numbers and sends the ultrasonic echo signals to the ultrasonic instrument, and closes the other ultrasonic echo signals. The system and method do not sacrifice the repetition frequency of an ultrasonic flaw detection system, which means that the production efficiency and precision are not affected.

Description

technical field [0001] The invention relates to the field of ultrasonic probes, in particular to a logical ultrasonic probe array based on comparison and gating. Background technique [0002] With the development of industrial technology, more and more ultrasonic probe arrays are used in industrial ultrasonic flaw detection systems. The present invention is based on the comparator array and the gating control array, and the multi-channel signals of the same type in the ultrasonic probe array are synthesized into one signal according to the principle of maximum amplitude. Flaw detection productivity and accuracy. [0003] The patent document CN 106821414 A discloses a method and device for controlling the operation of a channel and a probe. A method of controlling operation of a channel including at least one transducer includes: comparing a voltage corresponding to a current flowing in the channel with an alarm voltage; and controlling operation of the channel based on a r...
