Description

Sensors with on-device AI function Integrated wired/wireless communication drive Noise sensor, its system, and its operation method The present invention relates to a noise sensor with an integrated wired/wireless communication drive and an on-device AI (Artificial Intelligence) function, a system thereof, and a method of operation thereof. More specifically, the invention relates to a noise sensor with an integrated wired/wireless communication drive and an on-device AI function that can check the condition of building structures, machinery, and equipment, collect real-time data, and analyze and predict potential risks such as wear, damage, and destruction of an object, a system thereof, and a method of operation thereof. Generally, in the case of architectural structures or mechanical devices, phenomena appearing inside or outside the facility, such as wall cracks caused by external forces, physical vibrations, impacts, and loads, and significant defects can be identified through safety inspections of the facility. Conventional noise sensors are used for industrial purposes by simply using the sound pressure level (dB(A)) of the noise to be measured directly by inspectors or managers, or applied to display boards or FNDs (7-segment) for display. Conventional noise sensors are provided as standalone components, and measurements are taken using various controller converters and control analyzers from different manufacturers. Additionally, during measurement, the noise and vibration frequency (Hz), amplitude, and sound intensity (dB) can be verified using an oscilloscope or monitor. On the other hand, conventional noise sensors have difficulty verifying whether the noise data matches the suitability for the relevant environmental conditions. In addition, since the noise level is measured primarily by converting only the sound intensity into dB, there is a problem in that it is difficult to accurately detect abnormal defects along with the frequency, amplitude, and sound intensity of the measurement target when judging and predicting defect conditions of the measurement target. In addition, due to sensors from different manufacturers and various sensor drivers (signal converters, communication transmission devices), issues regarding communication and wired/wireless compatibility, as well as protocol compatibility mismatches, have occurred. In addition, conventional noise sensors transmit only raw data converted into electrical signals of the sensor signal, thereby providing an unreasonable environment unsuitable for artificial intelligence processing of small and medium-sized data, which involves re-computing and processing the raw data in the storage of a stored cloud server system to implement AI as big data. In addition, conventional noise sensors are standardized into mostly passive sensor products by quantizing analog signals to convert them into digital signals and receiving the converted data to display it on their own or to display it on LCD monitors, electronic display boards, instrument panels, etc., which serve as display means for devices of remote terminals. In addition, there are difficulties in users or safety managers individually inspecting and maintaining the object to be measured in a confined space exposed to danger in order to measure the noise status of the object.
