Detailed Description

The embodiment of the utility model provides an acoustic imager, which is a handheld acoustic imager, and a host and a sensor array assembly of the acoustic imager can be quickly disassembled and assembled, so that a user can conveniently disassemble and independently overhaul the host and the sensor array of the acoustic imager, and the user can conveniently replace the sensor array assembly or the host for the acoustic imager.

The acoustic imaging is based on an acoustic sensor array measurement technology, the position of a sound source is determined according to a phased array principle by measuring the phase difference of signals of sound waves reaching each microphone in a certain space, the amplitude of the sound source is measured, the distribution of the sound source in the space is displayed in an image mode, namely a cloud image-sound image of the spatial sound field distribution is obtained, and the intensity of the sound source is represented by the color and the brightness of the image in the sound image.

The fixed acoustic imager can be seen in fig. 1, and the acoustic imager is composed of a camera 1, a noise monitoring sensor 2, an acquisition card 3, a processor 4, a diagnosis server 5 and a lifting frame 6. Therefore, when the fixed acoustic imager is used, a plurality of devices need to be connected, the operation is troublesome, and the fixed acoustic imager is not convenient to carry.

To enhance the flexibility of use of acoustic imagers, hand-held acoustic imagers have been developed in the industry.

As shown in fig. 2, the handheld acoustic imager includes a main body module 1, and a supporting member 2 and a supporting pad 4 disposed on the main body module 1, wherein a display screen 11 is disposed on one side surface of the main body module 1, a microphone array module and a camera are disposed on the other side surface of the main body module 1, the supporting member 2 is movably connected to the main body module 1, and at least supporting positions for locking the relative positions of the two are respectively formed on the two side surfaces of the main body module 1.

Generally, the acoustic imager is inevitably subjected to maintenance during the application process, such as maintenance or replacement of the host or the sensor array. The host computer of the acoustic imager may need to be connected to other sensor arrays to test their functional status, or the sensor arrays may need to be connected to other host computers to test their operational status, or alternatively, a new host computer or sensor array assembly may need to be replaced. For the existing handheld acoustic imager, due to the high integration level, the user is inconvenient to disassemble and assemble, and therefore the handheld acoustic imager can hardly be overhauled and replaced independently.

In addition, the arrangement and the number of the acoustic sensors in the sensor array have great influence on acoustic imaging, generally, the spacing between the sensor elements is close, so that high-frequency acoustic signals can be better distinguished, and the spacing between the sensor elements is far, so that low-frequency acoustic signals can be better distinguished; moreover, the number of acoustic sensors has a large influence on the resolution and the price of the product. In addition, the power consumption of a screen in the acoustic imager is the largest, and a large screen can display more pictures, but can bring shorter endurance and heavier weight, so that the user experience is influenced.

Different users or under different scenes have different requirements on acoustic imaging, so that the users may have the requirement of replacing different acoustic sensors for the acoustic imager, but the traditional handheld acoustic imager cannot be detached by the users due to high integration level, and thus the handheld acoustic imager can only carry acoustic sensors with different performances and configurations.
