Description

TECHNICAL FIELD

[0001] The present application relates to the field of intelligent control, and in particular to an industrial process supervision and management system based on multi-modal data processing. BACKGROUND

[0002] With the rapid development of Industry 4.0 and intelligent manufacturing technology, modern industrial production puts forward higher requirements for the real-time, accuracy and intelligent level of process monitoring systems. Traditional industrial monitoring systems mainly rely on single modal data (such as vibration signals or temperature parameters) for equipment state analysis, which has the following significant defects:

[0003] 1. Insufficient multi-source heterogeneous data fusion capability:

[0004] Existing systems usually use separate sensor networks to collect visual, acoustic and environmental parameter data, but lack a hardware-level time alignment mechanism, resulting in a timestamp deviation of multi-modal data exceeding milliseconds, which directly affects the timeliness of anomaly detection.

[0005] 2. Poor dynamic adaptability of anomaly detection:

[0006] Traditional methods rely on fixed threshold criteria, but when the equipment working condition changes dynamically with the production load, the static threshold will cause the false alarm rate to rise. In addition, existing dynamic modeling techniques cannot solve the problem of nonlinear coupling of multi-modal data, and cannot accurately define the dynamic threshold curve.

[0007] 3. Lack of explainability of intelligent decision-making:

[0008] Current systems mostly use black-box deep learning models, which can detect some abnormal events, but lack causal reasoning ability. Operators cannot trace the logical basis, leading to delayed or inappropriate control parameter adjustments, which seriously affects fault repair efficiency.

[0009] 4. Limited visual interaction effect:

[0010] Existing monitoring interfaces mostly use two-dimensional charts, which cannot intuitively present the full life cycle state of the equipment and the spatial distribution of anomalies. Although digital twin technology has been introduced, it has not yet achieved accurate spatiotemporal mapping of multi-modal data, especially lacking multi-dimensional traceability of abnormal events.

[0011] 5. Low efficiency of cross-domain collaborative control:

[0012] Independent monitoring-control architecture only supports one-way instruction transmission, and there is a lack of feedback correction mechanism between the decision unit and the execution mechanism. When the device response deviates from the expectation after parameter adjustment, the system cannot optimize the control strategy in real time, which may cause secondary abnormalities.

[0013] In view of the above problems and / or existing ones, an industrial process supervision and management system based on multi-modal data processing is proposed. SUMMARY

[0080] Embodiment 2

[0081] The second embodiment of the application differs from the first embodiment in that it further includes a test preparation and implementation process:

[0082] Test preparation and implementation process:

[0083] This example selects a certain automobile manufacturing enterprise welding production line as the test scene, verifies the performance of the industrial process supervision and management system based on multi-modal data processing in complex industrial environment. The test object includes 12 welding robots, 8 conveyor belt drive motors and supporting cooling systems, and the total monitoring area covers 1200 square meters. The experimental period is 30 consecutive days, and the total amount of data collected is 2.3TB.

[0084] Hardware deployment:

[0085] The visual sensor array 101 is composed of 36 multispectral industrial cameras 101a and 6 infrared thermal imagers 101b, arranged in an interleaved manner 3 meters above the welding station track, covering all the welding gun working area. Each multispectral camera collects a 1280x1024 resolution video stream at 30fps, and the infrared thermal imager realizes 360° scanning through a rotating pan-tilt, with a temperature detection range of 0-500℃.

[0086] The acoustic monitoring unit 102 contains a 24-channel microphone array, with a sampling rate of 48kHz per channel, deployed around the key nodes of the equipment at a height of 1.5 meters, monitoring the welding arc soundprint and motor bearing abnormal noise.

[0087] The environmental parameter sensor group 103 contains 32 vibration sensors (range 0-50g) and temperature and humidity sensors (accuracy ±0.5℃), arranged at 1.2 meter intervals on the equipment base.

[0088] Data synchronization mechanism:

[0089] A hardware-level pulse trigger mechanism is used, with a GPS-synchronized clock chip built into the environmental parameter sensor group 103, generating a synchronization pulse signal every 1 second. Tests show that the timestamp alignment error of the three modal data is <1ms, meeting the requirements of the dynamic modeling unit 301 for time sequence consistency.

[0090] Abnormality detection process:

[0091] The dynamic modeling unit 301 analyzes the multi-modal feature vectors with a 30-second window, calculates the root mean square value (RMS) of vibration, video frequency energy (0-15Hz) and acoustic MFCC variance. When generating the dynamic threshold curve by kernel density estimation, the cumulative distribution function confidence interval is set to [0.05, 0.95]. When the feature deviation of any two modalities exceeds the threshold value, the correlation decision unit 302 triggers a joint alarm.

[0106]

[0107] Time synchronization performance (Table 1): The multi-modal data alignment error is reduced to sub-millisecond level (0.5-0.8ms) by the hardware-level pulse trigger mechanism, which reduces the error by 98.3% compared with the traditional software synchronization method. This feature ensures that the dynamic modeling unit 301 can accurately establish a spatio-temporal correlation model of multi-modal features, avoiding misjudgment caused by time sequence misalignment.

[0108] Abnormality detection efficiency (Table 2): The response time is shortened by 56.3%-76.5% by the dual-mode correlation detection, and the composite abnormality detection achieves a response speed of 1.2 seconds. Through the multi-source confidence fusion of the correlation decision unit 302, the false positive rate is controlled at 0.9%-3.2%, which is reduced by 42.7% compared with single-mode detection. This shows that the deep residual network of the multi-modal feature generation unit 202 and the MFCC feature extraction effectively improve the abnormality representation ability.

[0109] Decision optimization effect (Table 3-4): The double inference mechanism of the Bayesian network improves the fault positioning accuracy to 95.2%-98.5%, and the causal chain depth reaches 3-5 levels, which is 29.6 percentage points higher than the traditional expert system. The closed-loop response time of the parameter control unit 402 is less than 3 seconds, and the steady-state error is less than 1.2%, proving that the causal chain analysis of the fault reasoning engine 401 can effectively guide the actuator adjustment.

[0110] Visualization performance (Table 5): The heat map update delay of the digital twin map 501 is less than 92ms, which is 4.8 times higher than the traditional SCADA system, meeting the real-time monitoring requirements. The three-mode data synchronous playback function of the event trace panel 502 (Table 6) makes the effective alarm rate reach 98.3%, and the false alarm rate is less than 1.5%, which is significantly better than the existing single-dimensional alarm system.

[0111] The data of the embodiment prove that the system realizes breakthroughs in detection speed, positioning accuracy and decision reliability through multi-modal data fusion and dynamic modeling. In particular, the hardware-level time synchronization, double-modal correlation decision and Bayesian double inference mechanism effectively solve the technical bottlenecks of the traditional industrial monitoring system, such as timing misalignment, single-source misjudgment and insufficient causal analysis.
