[0024] The data processing method of an intelligent security integrated management and control platform operates as follows: First operational phase: Multi-source heterogeneous data fusion and processing: A distributed sensor network is initiated to synchronously collect video surveillance streams, audio sensor signals, environmental parameter time-series data, and biometric features to generate a raw security dataset. Data cleaning is performed through a multimodal preprocessing engine, inter-frame differential decluttering filtering is applied to the video stream, wavelet domain voice separation is performed on the audio signal, Z-score normalization is performed on the sensor data, and timestamp indexing is used to align all data sources. The standardized data is then input into a hybrid model composed of a 3D convolutional neural network and a recurrent neural network to extract motion trajectory features, abnormal voiceprint fingerprints, and environmental mutation parameters. A feature fusion layer generates a security feature vector set with unified dimensions, establishing a data foundation for real-time event detection.
[0025] Second operational phase: Dynamic risk assessment decision chain: The security feature vector set is input into a pre-trained YOLO event detection model to identify threat types such as intrusion, fire, violent behavior, and equipment failure. The model outputs an event confidence score. When the confidence score exceeds a threshold, the rule engine is activated to query similar event records in the historical security database. Combining factors such as the sensitivity of the incident location, the urgency of time, and the potential spread rate, a normalized risk index is calculated. Based on a preset threshold, the risk level is dynamically classified, triggering a response decision tree. Low-risk events push early warning messages to user terminals, medium-risk events trigger access control and alarm devices, and high-risk events activate fire protection systems and emergency robots, achieving real-time matching of response strategies and threat levels.
[0026] Third operational phase: Closed-loop self-optimization mechanism: When executing response actions, metrics such as response time, false alarm rate, and event resolution rate are collected simultaneously to generate a feedback dataset. An incremental learning algorithm is used to associate the feedback data with the historical database to optimize the parameters of the risk assessment model and the event detection threshold. The reinforcement learning module simulates response paths in multiple scenarios, updates the weights of the response strategy reward function, improves resource allocation efficiency, and uses blockchain to store the hash value of key decisions. When abnormal data tampering is detected, a traceability audit is automatically initiated to ensure the verifiability of security decisions.
[0027] Fourth operational phase: Edge collaboration and resource scheduling: A lightweight feature extraction model is deployed at the data acquisition end to pre-filter the raw data, upload high-confidence feature vectors to the central platform, dynamically adjust the sensor sampling frequency based on the energy efficiency management function, reduce device power consumption during low-threat periods, build a multi-tenant data sandbox, realize permission isolation of different security areas, and exchange event response protocols with third-party systems through standardized API interfaces to form a cross-platform collaborative defense network.
[0028] Fifth operational phase: Continuous environmental adaptation The system periodically analyzes its operation logs to identify variables such as changes in ambient light, new device types, and new attack patterns. It adjusts the sensitivity parameters of the feature extraction model through an adaptive learning mechanism to enhance robustness in complex scenarios. When an increase in the frequency of regional threats is detected, the system automatically increases the risk assessment weight coefficient for that region, creating a local reinforcement effect for threat defense and enabling the system to continuously evolve.
