In recent years, vibrations caused by construction have garnered widespread attention. Currently, vibration impact assessment methods primarily use empirical models or numerical simulations to predict vibration amplitudes, regularly perform vibration measurements on adjacent buildings, or establish monitoring systems. By comparing these with vibration threshold standards, the adverse effects of construction activities on the surrounding environment and adjacent buildings can be mitigated.

[0057] The vibration assessment method provided in the embodiments of the present application can be applied to computer devices such as mobile phones, tablet computers, wearable devices, vehicle-mounted devices, augmented reality (AR) / virtual reality (VR) devices, laptop computers, ultra-mobile personal computers (UMPCs), netbooks, and personal digital assistants (PDAs). The embodiments of the present application do not impose any restrictions on the specific types of computer devices.

[0058] In areas with high building density, land supply is tight, which means that new construction projects are often subject to space constraints. Construction operations, including drilling, demolition, excavation, etc., often cause significant ground vibrations, posing potential risks to adjacent buildings and the ultra-precision instruments and equipment therein. In recent years, vibrations caused by construction have attracted widespread attention. Existing regulations have set acceptable vibration thresholds and require vibration monitoring during construction to prevent damage to adjacent buildings. However, existing construction vibration assessment methods are insufficient in protecting ultra-precision instruments. In existing buildings, especially in places such as hospitals, a large number of expensive ultra-precision instruments are placed, but the potential impact of environmental vibration on the normal operation of these instruments is often ignored. The reasons are specifically reflected in the following facts:

[0059] For a given type of existing building, its vibration threshold is fixed. However, it may contain a wide variety of ultra-precision instruments, each with its own specific vibration threshold. Current vibration monitoring systems cannot individually assess each ultra-precision instrument to ensure that it is properly protected.

[0060] Current methods for assessing vibration impacts include conservative predictions based on empirical models or numerical simulations, which often overestimate actual vibration levels. Furthermore, while peak particle velocity (PPV) is widely used as a vibration metric in the construction industry, vibration thresholds for ultra-precision instruments are typically expressed in the frequency domain, such as root mean square velocity in a 1 / 3 octave band. Therefore, vibration signals need to be processed in the frequency domain to meet the requirements of ultra-precision instruments.

[0061] Conventional construction vibration thresholds are typically designed to measure levels associated with building damage, but ultra-precision instruments have vibration thresholds far below the standards typically adopted in the construction industry. Therefore, vibration monitoring equipment needs to be more sensitive in order to measure even small vibrations.

[0062] Given the frequent use of ultra-precision instruments, regular vibration measurements cannot fully guarantee their performance and maintainability during use. Therefore, it is necessary to propose a real-time vibration monitoring solution to ensure timely vibration monitoring and protection of the operating environment of ultra-precision instruments.

[0063] Based on the above situation, the embodiments of the present application propose a vibration assessment method, apparatus, system, device and storage medium.

[0064] See also Figure 1 , Figure 1 3 is a flow chart of a vibration assessment method provided in an embodiment of the present application. For ease of explanation, only the parts related to this embodiment are shown.

[0065] like Figure 1 As shown, the vibration assessment method provided in this embodiment includes the following steps:

[0066] S1. Obtain real-time vibration signals and real-time status images of monitoring points;

[0067] Specifically, for step S1, the main purpose is to obtain the real-time vibration signal and real-time status image of the monitoring point at the current time. The monitoring point can be a construction site where construction activities are carried out, a part of the construction site, or the entire construction site; in addition, the number of monitoring points can be one or more.

[0068] S2. Process the real-time vibration signal to obtain the current vibration information of the monitoring point;

[0069] Specifically, in step S2, after obtaining the current real-time vibration signal of the monitoring point, a series of signal processing is performed on the real-time vibration signal to obtain the current vibration information of the monitoring point, and the vibration information is used to represent the current vibration level of the monitoring point.

[0070] S3 performs image processing on the real-time state image to obtain the source position of the real-time vibration signal;

[0071] Specifically, in step S3, after obtaining the current real-time status image of the monitoring point, the real-time status image is processed to obtain the vibration source position corresponding to the real-time vibration signal currently emitted by the monitoring point.

[0072] S4. Based on the vibration information and the vibration source location, the vibration assessment of the monitoring point is performed to generate the current vibration assessment results of the monitoring point;

[0073] Specifically, for step S4, after obtaining the current vibration information and vibration source position of the monitoring point, a spatial vibration prediction model is established using the vibration source position information and the vibration levels of all monitoring points. Combined with the vibration threshold database of ultra-precision instruments, a vibration assessment is performed on the monitoring point to assess the impact of the vibration of the monitoring point on each ultra-precision instrument. The current vibration impact of the monitoring point on the ultra-precision instrument is generated, thereby achieving personalized vibration impact assessment for each ultra-precision instrument.

[0074] Optionally, in some embodiments, step S1 of “obtaining a real-time vibration signal and a real-time status image of a monitoring point” may specifically include:

[0075] S11. sensing the real-time vibration of the monitoring point and generating a vibration electronic signal;

[0076] S12 modulates the vibration electronic signal and converts it into a corresponding vibration voltage signal;

[0077] S13. Shoot the spatial status of the monitoring point in real time to obtain a real-time status image.

[0078] In a specific embodiment, step S1 first involves acquiring a real-time vibration signal from the monitoring point. This real-time vibration signal can be acquired through a sensing system. The specific process includes: to measure minute vibrations, a highly sensitive piezoelectric accelerometer is used to sense the current real-time vibration conditions at the monitoring point and generate an electronic signal. The electronic signal is then modulated by a charge amplifier and converted into a voltage signal. The modulated voltage signal is then received by a data acquisition device and ultimately transmitted to a computer for data processing. A real-time status image of the monitoring point is then acquired, for example, by monitoring the location of the vibration source through a sensing system and using a camera to monitor the location of the vibration source in real time. The monitoring process includes the camera capturing a real-time image of the construction site's status, and the captured image is transmitted to a computer for subsequent image processing. This process ensures accurate monitoring and recording of the vibration source location.

[0079] Optionally, in some embodiments, step S2 of “processing the real-time vibration signal to obtain current vibration information of the monitoring point” may specifically include:

[0080] S21. The vibration voltage signal is filtered and sensitivity modulated to obtain an acceleration time domain signal;

[0081] S22. Integrate the acceleration time domain signal to obtain a velocity time domain signal;

[0082] S23. Perform Fourier transform on the velocity time domain signal to obtain a 1 / 3 octave sub-time domain signal;

[0083] S24. Calculate the 1 / 3 octave RMS velocity based on the 1 / 3 octave sub-time domain signal;

[0084] S25. Select the maximum value of the 1 / 3 octave RMS velocity as the current vibration information of the monitoring point.

[0085] In a specific embodiment, for step S2, after obtaining the real-time vibration signal collected by the camera device, it is necessary to perform signal processing on the real-time vibration signal. First, the vibration voltage signal is filtered and sensitivity modulated to obtain an acceleration time domain signal. Then, the acceleration time domain signal is integrated to obtain a velocity time domain signal. Then, the velocity time domain signal is Fourier transformed and inverse transformed to obtain a 1 / 3 octave sub-time domain signal. Finally, the maximum value of the 1 / 3 octave sub-time domain signal of all monitoring points is selected as the current vibration information of the monitoring point to characterize the vibration level of the monitoring point. Unlike the peak particle velocity (PPV) widely used as a vibration index in the existing construction industry, the vibration threshold of ultra-precision instruments is usually expressed in the frequency domain, such as the root mean square velocity in the 1 / 3 octave. Therefore, this embodiment processes the vibration signal in the frequency domain to meet the requirements of ultra-precision instruments.

[0086] Another key function in the software system is to establish a spatial vibration prediction model using the vibration source location information and the vibration levels of all monitoring points. Combined with the vibration threshold database of ultra-precision instruments, it can realize personalized vibration impact assessment for each ultra-precision instrument.

[0087] Optionally, in some embodiments, step S3 of “performing image processing on the real-time status image to obtain the vibration source position corresponding to the real-time vibration signal” may specifically include:

[0088] S31 performs image recognition processing on the real-time state image to obtain the corresponding image features;

[0089] S32. After preprocessing and feature extraction of the image features, the corresponding vibration features are obtained;

[0090] S33. Use pattern recognition technology to analyze vibration characteristics and determine the vibration source location of real-time vibration signals; pattern recognition technology includes machine learning algorithms or deep learning algorithms.

[0091] In a specific embodiment, for step S3, this embodiment uses a camera device to monitor the vibration source position in real time. The monitoring process includes the camera device capturing the real-time status image of the monitoring point in real time, and then performing image recognition processing on the real-time status image according to image recognition technology to obtain image features corresponding to the real-time status image. In order to eliminate noise or unnecessary features in the image, various preprocessing technologies can be used, such as filtering, smoothing, contrast enhancement and other preprocessing technologies. Then, feature extraction is performed on the preprocessed image features to extract vibration-related features, such as vibration features such as amplitude, frequency and phase. Finally, pattern recognition technology, such as machine learning or deep learning algorithms, is used to analyze the vibration features to determine the vibration position of the real-time vibration signal. These algorithms can learn how to extract useful feature information from images by training a large amount of data; in addition, in order to improve the accuracy of recognition, a series of post-processing can be performed as needed, such as smoothing, interpolation or optimization, to ensure accurate monitoring and recording of the vibration source position.

[0092] Optionally, in some embodiments, step S4 of “performing a vibration assessment on the monitoring point based on the vibration information and the vibration source location to generate a current vibration assessment result of the monitoring point” may specifically include:

[0093] S41. Construct a spatial vibration prediction model based on vibration information and vibration source location;

[0094] S42. Obtaining the vibration threshold database of the target instrument;

[0095] S43. Based on the spatial vibration prediction model and the vibration threshold database, perform vibration assessment on the monitoring point and generate the current vibration assessment result of the monitoring point.

[0096] In a specific embodiment, for step S4, after obtaining the current vibration information and vibration source position of the monitoring point, a corresponding spatial vibration prediction model is constructed based on the vibration information and vibration source position, and then combined with the vibration threshold database of the target instrument (ultra-precision instrument), the vibration threshold of the target instrument is read therefrom. Finally, based on the spatial vibration prediction model and the vibration threshold, the vibration impact of the monitoring point on the target instrument is evaluated, and the vibration evaluation result of the monitoring point on the target instrument due to vibration at the current moment is generated, thereby realizing personalized vibration impact evaluation for each ultra-precision instrument.

[0097] Optionally, in some embodiments, Figure 2As shown, after step S4 "performing a vibration assessment on the monitoring point based on the spatial vibration prediction model and the vibration threshold database to generate a current vibration assessment result of the monitoring point", the following steps may be specifically included:

[0098] S5. If the vibration assessment result is higher than the preset vibration threshold, a vibration warning message is generated and the vibration warning message is sent to the bound target terminal to prompt the target instrument to be affected by vibration;

[0099] S6. If it is determined that the vibration evaluation result is not higher than the preset vibration threshold, a data display interface including the vibration evaluation result is displayed.

[0100] In a specific embodiment, after step S4, that is, after generating the current vibration assessment result of the monitoring point, a real-time alarm and data display step is also included. If the vibration estimation result is determined to be higher than the preset vibration threshold of the target instrument, that is, once the vibration is monitored to exceed the vibration threshold of the target instrument, a vibration warning information is generated, and a visual alarm and / or a sound alarm is issued through a pre-designed real-time alarm graphical interface, and the vibration warning information is immediately sent to the bound target terminal, for example, the vibration warning information is sent to the target terminal of the bound target user via email. The vibration warning information may include the current vibration monitoring status and a list of ultra-precision instruments that may be affected, so as to notify the relevant responsible parties to take further action; if the vibration estimation result is determined to be not higher than the preset vibration threshold of the target instrument, the vibration impact is displayed through a pre-designed data display graphical interface, including the current vibration information and the real-time operating status of the target instrument. In view of the fact that users usually have limited knowledge of vibration and dynamics, a user-friendly graphical interface is used to display the vibration impact to improve practicality; and the data display graphical interface can also display real-time vibration assessment, with high real-time performance.

[0101] In addition, this embodiment also provides a data storage function, which stores the original vibration data and vibration assessment results through the software system for subsequent tracing, query and data statistics.

[0102] In summary, the vibration assessment method provided by this embodiment first obtains the real-time vibration signal and real-time status image of the monitoring point; then performs signal processing on the real-time vibration signal to obtain the current vibration information of the monitoring point; then performs image processing on the real-time status image to obtain the vibration source position of the real-time vibration signal; finally, based on the vibration information and the vibration source position, the monitoring point is vibration assessed to generate the current vibration assessment result of the monitoring point. It can be seen that this embodiment can realize personalized assessment of the vibration of the operating environment of each ultra-precision instrument and can ensure that each ultra-precision instrument is properly protected. In view of the fact that ultra-precision instruments are of many types and widely distributed, and each instrument has its own specific vibration threshold, ensuring that each ultra-precision instrument is properly protected effectively solves the shortcomings of existing construction vibration assessment methods that cannot meet the protection requirements of ultra-precision instruments.

[0103] In order to facilitate understanding of the vibration evaluation method provided in this embodiment, this embodiment also provides a vibration evaluation system for implementing the vibration evaluation method, such as Figure 3 As shown, the system may specifically include a sensing system A and a software system B connected to the sensing system A, wherein the sensing system A includes a signal processing device A1 and an image processing device A2, the signal processing device A1 is used to obtain the real-time vibration signal of the monitoring point, and perform signal processing on the real-time vibration signal, after obtaining the current vibration information of the monitoring point, the vibration information is transmitted to the software system B; the image processing device A2 is used to obtain the real-time status image of the monitoring point, and perform image processing on the real-time status image, after obtaining the vibration source position of the real-time vibration signal, the vibration source position is transmitted to the software system B; the software system B is used to perform vibration evaluation on the monitoring point based on the received vibration information and vibration source position, and generate the current vibration evaluation result of the monitoring point.

[0104] Specifically, such as Figure 4 As shown, the vibration assessment system consists of a sensing system and a software system, wherein the main task of the sensing system is to collect real-time vibration signals and monitor the position of the vibration source. The sensing system may specifically include a camera, a piezoelectric accelerometer, a charge amplifier and an acquisition instrument. In the actual operation process, in order to measure tiny vibrations, this embodiment uses highly sensitive piezoelectric accelerometers. These piezoelectric accelerometers sense vibrations and generate electronic signals. Subsequently, these electronic signals are modulated by a charge amplifier and converted into voltage signals. The modulated voltage signal is then received by a data acquisition instrument and ultimately transmitted to the computer of the software system for data processing. Another key component in the sensing system is vibration source position monitoring, which uses a camera to monitor the position of the vibration source in real time. The monitoring process includes the camera capturing the status image of the construction site in real time, and the captured image is transmitted to the computer for subsequent image processing.

[0105] The software system may include a host computer (computer) whose primary tasks are to process raw vibration data, perform vibration impact assessment, visualize data, and trigger alarms when vibration thresholds are exceeded. Furthermore, the software system includes real-time data storage capabilities to meet future needs, such as remote data downloading, subsequent data processing, and data sharing.

[0106] like Figure 5 Figure 2 illustrates the signal processing flow within the software system. One of its core functions is vibration impact assessment for ultra-precision instruments based on vibration spectrum analysis. This process begins with the voltage signal acquired by the sensing system and proceeds through a series of processing steps, including filtering, sensitivity adjustment, integration, and Fourier transform. These steps convert the voltage signal into a 1 / 3 octave RMS velocity, with the maximum value selected as the vibration level at the monitoring point. Another key function within the software system is the development of a spatial vibration prediction model using vibration source location information and vibration levels at all monitoring points. Combined with a database of ultra-precision instrument vibration thresholds, this model enables personalized vibration impact assessment for each ultra-precision instrument. Furthermore, the software system incorporates real-time alerts and a graphical interface for data display. Given that end users typically have limited knowledge of vibration and dynamics, a user-friendly graphical interface is employed to display vibration impacts. Once detected vibration exceeds the ultra-precision instrument's vibration threshold, the interface issues visual and audible alerts and immediately sends information via email, including the current vibration monitoring status and a list of potentially affected ultra-precision instruments, to notify responsible parties for further action.
