Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] In order to improve the measurement accuracy and measurement efficiency of large bulk items. The present invention combines the advantages of ultrasonic detection technology in underwater, and develops a set of large-scale bulk item weighing system based on ultrasonic phase control technology. System structure and detection objects such as figure 1 As shown, the system consists of an ultrasonic array module (transducer), a control box module and a PC display module. The shape of the ultrasonic array is as follows: figure 2 As shown, the length is 215.5mm, the width is 60mm, and the height is 51.32mm. The diameter of the connector connecting the cable is 90mm, and the height is 65mm.

[0023] image 3 The cross-sectional view of the array is shown. The internal structure of the array is composed of acoustic lens, 32-PZT ceramic element, stainless steel shell...

Abstract

The invention relates to an ultrasonic-detection-technique-based article weighing system comprising an ultrasonic array module. The ultrasonic array module is focused in a width direction and a phase control technique is employed. With the phase control technique, deflecting focusing of an acoustic beam in a width direction is realized, so that an objective of ship body scanning can be achieved and thus a three-dimensional form of an underwater real ship. Whether a three-dimensional form of an object is placed on a ship is compared and analyzed and a drainage amount difference before and after article loading of the real ship is obtained by calculation, wherein the difference expresses the mass of the placed object. According to the invention, the deflecting focusing of the acoustic beam is realized by the phase control technique, so that an objective of scanning of a measured object is achieved and thus scanning efficiency is improved. With an acoustic lens, the acoustic beam width is reduced, so that the scanning resolution ratio is improved.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic detection, and in particular relates to an item weighing system based on the ultrasonic detection technology. Background technique [0002] The weighing of large bulk items usually has technical requirements such as weighing efficiency, weighing accuracy, and convenient operation; in addition, to complete the weighing of large bulk items, it will consume a lot of manpower and material resources, and even the weighing accuracy cannot be guaranteed. effectiveness. [0003] In this field, many researchers have proposed a large number of weighing methods or technologies, and even applied the related properties or principles of light, sound, and electricity to item weighing, and conducted experiments. However, the weighing method or technology proposed above still cannot effectively meet the weighing technical requirements. As far as item weighing technology is concerned, technical improvements ar...
