[0004] However, there are still the following problems in the prior art:

[0005] When monitoring vibration sources, most existing technologies are suitable for detecting large-scale vibration events, such as earthquakes, abnormal operation of large machinery, etc., but have poor sensitivity when monitoring small regular vibration sources near the ground in real life, such as the vibration of large vehicle engines, the vibration of pile drivers, etc., and are unable to accurately and timely determine the vibration source, resulting in low accuracy and high false alarm rate. Summary of the invention

[0006] To this end, the present invention provides an intelligent vibration monitoring and adaptive optimization device based on a neural network to solve the problem of poor sensitivity when monitoring small regular vibration sources near the ground in real life, such as the vibration of large vehicle engines, the vibration of pile drivers, etc., and the inability to accurately and timely determine the vibration source, resulting in low accuracy and high false alarm rate.

[0007] To achieve the above object, the present invention provides an intelligent vibration monitoring and adaptive optimization device based on a neural network, which comprises:

[0011] If the data volume is greater than or equal to the capacity of the vibration list and / or the time interval between two vibration events is less than a preset value and the time is discontinuous, feature extraction is performed on the original vibration data and the feature data is submitted to the neural network model;

[0016] Further, the vibration monitoring unit determines whether to send an interrupt signal to wake up the microcontroller, wherein:

[0017] If the detected vibration signal exceeds the preset vibration signal threshold, an interrupt signal is triggered to wake up the microcontroller, and the timestamp of the wake-up time is stored in the data list;

[0018] Or, continue monitoring until the microcontroller is woken up by the real-time clock.

[0019] Furthermore, the analysis and determination unit determines the submission status of the data based on the amount of data or the time interval in the data list, wherein:

[0020] If the data volume is greater than or equal to the capacity of the vibration list and / or the time interval between two vibration events is less than a preset value and the time is discontinuous, determining that the submission status is submittable;

[0021] Or, the submission status is unsubmittable and is continuously monitored.

[0022] Furthermore, the process of extracting features from the original vibration data by the analysis and determination unit includes:

[0023] Preprocessing of raw vibration data, including filtering, noise reduction and detrending;

[0024] Extract the variance characteristics, peak characteristics and power spectrum density characteristics of the preprocessed vibration data.

[0025] Furthermore, the process of calculating the vibration trigger characterization coefficient by the analysis and determination unit includes:

[0026] Determine the ratio of the variance characteristic to the reference variance characteristic as the first vibration influence coefficient;

[0027] Determine the ratio of the peak characteristic to the reference peak characteristic as the second vibration influence coefficient;

[0028] Determine the ratio of the power spectrum density feature to the reference power spectrum density feature as the third vibration influence coefficient;

[0029] A weighted sum of the first vibration influence coefficient, the second vibration influence coefficient, and the third vibration influence coefficient is determined as the vibration trigger characterization coefficient.

[0030] Furthermore, the analysis and determination unit is pre-set with vibration trigger characterization coefficient intervals corresponding to different vibration sources.

[0031] Furthermore, the process of the analysis and determination unit identifying the vibration trigger source includes:

[0032] Determining a vibration triggering characterization coefficient interval in which the vibration triggering characterization coefficient is located;

[0033] If the vibration trigger characterization coefficient is greater than or equal to the vibration trigger characterization coefficient threshold, the vibration source corresponding to the vibration trigger characterization coefficient interval is determined to be a vibration trigger source.

[0034] Further, the vibration trigger characterization coefficient threshold is a variable value, wherein,

[0035] The neural network stores the vibration trigger characterization coefficient in real time to update the vibration trigger characterization coefficient threshold.

[0036] Further, the process of the vibration verification unit determining the accuracy of the identification by the analysis and determination unit includes:

[0038] If the vibration comparison similarity is greater than or equal to the vibration comparison similarity value threshold, it is determined that the analysis and determination unit has made an accurate identification.

[0039] Compared with the prior art, the present invention is provided with a vibration monitoring unit, a data storage unit, an analysis and determination unit, a vibration verification unit and an optimization unit. The vibration monitoring unit is used to determine whether to send an interrupt signal to wake up the microcontroller, the data storage unit is used to record the timestamp of each wake-up moment and store the timestamp in a data list, the analysis and determination unit is used to determine the submission status of the data, and perform feature extraction on the original vibration data to calculate the vibration trigger characterization coefficient and identify the vibration trigger source, the vibration verification unit calculates the vibration comparison similarity to determine the accuracy of the analysis and determination unit's identification, and the optimization unit is used to continuously collect new vibration samples and integrate the vibration samples into the existing model to improve the accuracy of the model and the sensitivity of vibration monitoring.

[0040] In particular, the present invention performs real-time threshold monitoring on the monitoring area to determine whether an interrupt signal needs to be sent to wake up the microcontroller. When monitoring vibration signals under the existing scheme, single-channel single-range measurement is mostly used. This scheme results in a very narrow range of threshold setting and a poor dynamic range. This monitoring scheme is more suitable for detecting large-scale vibration events, such as earthquakes, abnormal operation of large machinery, etc. If the existing scheme is still used when monitoring small regular vibration sources near the ground in real life, the monitoring sensitivity will be deteriorated and the vibration source cannot be identified in time. Based on this, the present invention considers using multi-range amplification factors to monitor the signal of the same vibration sensor to ensure that it can accurately capture vibration signals from weak to strong. Once a vibration signal is found, an interrupt signal is immediately sent to wake up the microcontroller. At the same time, the present invention sets a daily monitoring time. If there is no vibration signal during the daily monitoring time, the real-time clock will immediately wake up the microcontroller after the end of the daily monitoring time to store and store data, so as to ensure the full collection of vibration events and improve the monitoring sensitivity and comprehensiveness.

[0041] In particular, the present invention performs feature extraction on the original vibration data to calculate the vibration trigger characterization coefficient. In actual situations, the judgment of the vibration trigger source is mostly based on the original vibration data, but a part of the original vibration data is invalid data. Calculation according to this method will lead to a waste of computing power. Based on this, the present invention performs feature extraction on the original vibration data and determines the vibration trigger characterization coefficient based on the feature data, which reduces the calculation frequency and improves the calculation speed.

[0042] In particular, the present invention adopts a neural network model to determine the vibration trigger characterization coefficient based on feature data to identify the source of the vibration trigger. In real life, the judgment of the source of the vibration trigger is mostly based on a fixed threshold, but for small vibrations, their vibration frequency and amplitude are relatively small. If the fixed threshold judgment method is still used, it may lead to an increase in the false alarm rate or even missed alarms. Based on this, the present invention introduces an intelligent recognition technology based on a neural network, records each vibration data and combines previous data to calculate the vibration trigger characterization coefficient threshold in real time, reduces the number of false alarms, accurately judges the source of the vibration trigger, and improves the recognition accuracy of the source of the vibration trigger.

[0074] Or, the submission status is unsubmittable and is continuously monitored.

[0075] Specifically, the preset value is preset, and the durations of several vibration signals are obtained in advance and the average value of the durations is calculated. The preset value is set within 0.1 times to 0.2 times the average value of the duration.
