Sound testing and product shipment inspection (for cracks and fissures), which have relied on the sensory judgments of skilled workers and simple machines until now, can be automatically and more accurately determined by AI. This eliminates the risk of human judgment, improves work efficiency and productivity, addresses labor shortages, and reduces costs. Additionally, by combining it with the sound testing device developed by our company, reproducible data collection without variation can be achieved, regardless of who operates it. Furthermore, as the deep learning algorithms of AI learn from past images of good and defective products, the accuracy of judgment increases, enabling advanced determinations that surpass human recognition capabilities. We also accept "custom" system construction to meet various measurement needs of our customers, both hardware and software, so please feel free to consult or inquire. 【Measurement Examples】 ■ Product shipment sound testing ■ Infrastructure maintenance non-destructive testing ■ Analysis and research in medical and physiology ECG analysis / fracture determination, etc. *For more details, please refer to the PDF document or feel free to contact us.

The characteristics of sound and vibration that were not visible with conventional waveform data are converted into a "color image on the time axis" that reveals specific frequencies and sound pressure levels using our unique analysis method. This technique enables spectral analysis of sudden and non-stationary changes in sound and vibration, making it useful for phenomenon analysis and research in various fields. Additionally, in combination with our AI image recognition system, automatic judgment, which was difficult with FFT analysis or octave analysis, has become possible, in addition to visual judgment. 【Measurement Examples】 Product shipment impact testing (cracks, fractures) Impact testing of concrete and external wall infrastructure Analysis of abnormal sounds due to aging degradation of gearboxes Impact analysis of golf balls, research and development Crack detection in semiconductors Medical and physiological applications (ECG, fracture detection), etc. 【Features】 ■ Visualization of sound and vibration ■ Possible visual judgment ■ Automatic judgment possible in combination with AI image recognition system ■ Usable for analysis and research in various fields *For more details, please refer to the PDF document or feel free to contact us.

This document introduces examples of measurement systems that determine the presence of hard bone contamination in meat products. Many meat processing centers conduct full inspections using soft X-rays to check for bone fragments in meat. However, if bone fragments are embedded within fat, they cannot be distinguished. Our analysis shows that when bone fragments are sliced by a meat slicer, there is a change in a specific frequency range (sound/vibration). By attaching a vibration sensor to the bearing part of the rotating blade, we can capture this slight change in vibration and determine the presence or absence of bone fragments through FFT 1/3 octave analysis.

The outer circumference of railway vehicle wheels is fitted with iron tires, but when emergency brakes are applied to the vehicle and the wheels stop rotating while sliding on the rails, part of the tire becomes flat due to friction. When there is a flat spot, a vibration known as "gotton" occurs with each rotation of the wheel, resulting in a very uncomfortable ride. The "Wheel Flat Detection" system detects this during the passage of the train and reports it to the center. 【Basic Configuration of the Product】 ■ EC2320: USB AD Converter ■ Computer: Windows 10 ■ Input Box: ELMEC manufactured ■ Vehicle Detection Sensor Input Circuit: 3 channels ■ Acceleration Sensor: 4 channels ■ Charge Amplifier: 4 channels ■ Flat Detection Software: Custom Software *For more details, please refer to the related link page or feel free to contact us.

Actuators come in various forms, such as changing the angle of a passenger car's side mirror or moving dampers that alter the airflow of air conditioning. People generally do not feel discomfort from the normal sounds of motor rotation, but unstable sounds or unfamiliar and unpleasant noises do not necessarily have to be of high levels; rather, the frequency and pattern of the noise can cause discomfort. It is not feasible to spend a large amount of money on low-cost components like actuators. It is necessary to invest in a balanced manner according to the purpose, considering sensor selection, measurement fixture design, hardware costs, and software costs. Elmech provides suitable advice based on years of experience. *For more details, please refer to the PDF materials or feel free to contact us.*

The pre-shipment inspection items for the engine are quite complex, but among them, the inspection of engine noise and vibration is one important item. According to different engine RPM conditions, abnormal noise measurement and judgment are performed. This system is a PC measurement system, so it has intelligent features. When an NG (No Good) judgment is made, if the cause has already been identified based on the frequency range or combination of counts, the detected NG data is logically guided to display the cause in words. Customers can build complex judgment logic according to actual situations and require more accurate judgment results. *For more details, please refer to the PDF materials or feel free to contact us.*

One of the quality requirements for household refrigerator compressors is "quietness." The abnormal noise and vibration inspection conducted during the production line is not easily detectable with conventional FFT judgment devices due to surrounding noise and vibrations from manufacturing equipment. By using PJ-FFT (Point Joint FFT), which can determine instantaneous signal changes with a very short FFT window of a few milliseconds, automatic judgment becomes possible. There is also a function (optional) that not only determines OK/NG but also displays the cause of NG. This allows for logical derivation of detected NG data based on the frequency bands and combinations of counts when an NG judgment is made, enabling the specific display of the cause if it has already been identified. Our company can provide judgment methods such as area judgment, area accumulation, multiple level settings + area judgment, allowing customers to construct complex judgment logic according to actual situations and seek more accurate judgment results. *For more details, please refer to the PDF materials or feel free to contact us.
