Abstract
Description
Technical Field
[0001] This utility model relates to the field of ultrasonic testing technology, and in particular to a digital ultrasonic flaw detector and ultrasonic testing system. Background Technology
[0002] In industrial ultrasonic testing, gloves frequently come into contact with metal shavings and industrial wastewater contaminants. These contaminants are not only difficult to completely remove from touchscreens and control panels, but can also cause scratches and reduced touchscreen sensitivity, thus shortening the lifespan of the ultrasonic flaw detector. When industrial ultrasonic testing is conducted in dimly lit environments, such as nighttime operations or entering special spaces like inside spherical tanks or large pipelines, the limited light and small display size of the flaw detector increase the probability of operator errors due to poor visibility. Furthermore, some complex scanning rigs require two-handed operation, typically necessitating an additional operator—one to operate the rig and the other to operate the instrument—consuming significant manpower and reducing testing efficiency.

[0033] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0034] Please refer to Figures 1 to 3This embodiment discloses a digital ultrasonic flaw detector, including a housing 100, a motherboard 200, and a processor 300. A display screen 110 is mounted on the housing 100, and multiple function buttons 120 are located below the display screen 110. A probe interface 130 is located on one side of the housing 100. The motherboard 200 is installed inside the housing 100 and is connected to a microphone array 210 and a voice recognition chip 220. The microphone array 210 is embedded in the housing 100 and connected to the voice recognition chip 220. The microphone array 210 receives user voice commands and converts them into electrical signals. The voice recognition chip 220 processes the electrical signals to obtain voice recognition results. The processor 300 is electrically connected to the display screen 110, the probe interface 130, and the voice recognition chip 220.
[0035] This digital ultrasonic flaw detector solves the problem of cumbersome operation methods of traditional digital ultrasonic flaw detectors with their button panels and touch screens. It adopts voice control, reducing the frequency of use of traditional button panels and touch screens, thus increasing their lifespan; avoiding accidental operation of touch screens and function buttons in dimly lit environments; and freeing up the operator's hands, improving inspection efficiency. It employs a highly integrated, low-cost solution using a voice recognition chip to achieve voice control of the digital ultrasonic flaw detector. Voice control of the ultrasonic flaw detector is achieved without the need for a collared microphone. In inspection environments, such as large workpieces like spherical tanks and large pipelines, where the inspection position has a height difference from the ground or contains internal inspection spaces, it is necessary to move the inspection personnel to the inspection position using climbing scaffolds or suspended operations. Since this movement often involves a lot of physical movement, there is a certain risk of accidental detachment. This could result in microphone damage, increasing maintenance costs, or even leaving the microphone inside the workpiece, causing unpredictable consequences for subsequent production processes.
[0036] Please refer to Figure 1 The housing 100 has multiple sound holes 140 positioned corresponding to the microphone array 210. The microphone array 210 is fitted into the surface of the housing 100 through the sound holes 140 and a waterproof layer is applied. This ensures that the microphone array 210 does not reduce its sensitivity in receiving voice commands, while also preventing damage to the internal components from the external environment. These sound holes 140 facilitate the microphone array 210 in receiving sound signals, allowing sound to be received from multiple directions. This enables more accurate sound source localization and background noise elimination, improving the accuracy and stability of speech recognition.
[0037] Please refer to Figure 3The motherboard 200 is connected to an FPGA (Field Programmable Gate Array) chip 230, which is electrically connected to the processor 300. The FPGA chip 230 performs functions such as transmission control, digital signal acquisition, digital filtering, detection, and signal extraction.
[0038] Please refer to Figure 3 The motherboard 200 is equipped with an ultrasonic front-end analog circuit 240, which is electrically connected to the FPGA chip 230. The ultrasonic front-end analog circuit 240 includes an ultrasonic high-voltage transmitting circuit, an amplification circuit, and an ADC analog-to-digital conversion circuit.
[0039] Please refer to Figure 4 and Figure 5 The housing 100 has two through holes 150, which are positioned opposite each other on the back of the housing 100. The housing 100 also has a bracket 160, which includes a support rod 161 and a rotating shaft 162. The support rod 161 is connected to the rotating shaft 162, which passes through the through holes 150. Rotating the support rod 161 supports the housing 100, allowing the digital ultrasonic flaw detector to be placed stably on a table for easy operation.
[0040] Please refer to Figure 2 The motherboard 200 is equipped with a communication module 250, which includes one or more of a 5G module, a Bluetooth module, and a Wi-Fi communication module. The motherboard 200 integrates communication functions to enhance its network connectivity. The motherboard 200 features a communication module, which includes one or more of 5G, Bluetooth, or Wi-Fi communication modules, allowing for convenient selection and implementation of the desired network connection method. The motherboard 200 achieves wireless communication connectivity with external devices through the built-in communication module 250. Users can select the required communication module, or select two or three modules simultaneously; by connecting through the selected communication module, functions such as information transmission and data sharing can be achieved.
[0041] Please refer to Figure 3 The 220 speech recognition chip is an offline speech recognition chip. It adopts a mature, low-cost, portable, low-power, and highly integrated offline speech recognition chip. Offline speech recognition does not require a network connection, resulting in low cost and low power consumption. The 220 speech recognition chip has a built-in neural network processor that supports neural network and convolution operations, enabling functions such as speech recognition, voiceprint recognition, speech enhancement, and speech detection. It has strong echo cancellation and environmental noise suppression capabilities and supports multiple global languages, including Chinese, English, and Japanese.
[0042] The voice recognition chip 220 includes a noise reduction and enhancement module, a voice recognition module, and a voice matching module. The noise reduction and enhancement module processes the voice commands transmitted by the microphone array 210, reduces environmental noise, enhances human voice recognition, and transmits the processed command signal to the voice recognition module. The voice recognition module identifies the voice data carried by the voice command, extracts the valid voice data from the voice command, and transmits the valid voice data to the voice matching module. The voice matching module matches the valid voice data with the voice database and transmits the processing result to the processor 300 for further processing.
[0043] This embodiment also discloses an ultrasonic testing system, including the digital ultrasonic flaw detector 100 described above.
[0044] During testing, the operator issues a wake-up voice command, which is received by the microphone array 210, and a voice control wake-up icon is displayed on the screen 110. The operator issues parameter adjustment or operation commands, which are received by the voice recognition chip 220, and the processor 300 executes the corresponding parameter adjustment and control operations. The voice recognition chip 220, a commercially available low-cost, low-power, offline recognition chip, is used. It integrates signal acquisition circuitry, a neural network processor, memory, power management, and an interface controller. It can quickly recognize speech and send the processing results to the processor 300 through a common hardware interface. The processor 300 does not need to expend computing resources on speech recognition algorithms or add network transmission hardware circuitry.
[0045] It should be noted that this application pertains to improvements in the product's hardware structure and does not modify the computer programs involved in the testing process; furthermore, the computer programs involved are existing technologies.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
