This invention relates to the field of hazardous chemical monitoring technology, and more particularly to a method for monitoring the entire lifecycle of hazardous chemicals and predicting safety hazards based on LIMS. The method includes the following steps: Hazardous chemical information is entered into the LIMS by scanning electronic tags, and the operation steps and status are updated in real time when the chemical moves, forming updated data. The system compares the updated data with early warning rules, generates early warning information when an anomaly is triggered, and pushes it to the terminal server. The terminal server performs risk prediction based on the updated data and automatically generates disposal suggestions and graded contingency plans, ultimately forming a record of hazardous chemical hazard handling information, achieving intelligent monitoring and early warning throughout the entire process. This invention, by combining dynamic monitoring throughout the entire lifecycle, intelligent status recognition, and contextualized risk prediction, achieves accurate identification, early prediction, and graded disposal of hazardous chemical hazards, significantly improving the safety and emergency response capabilities of hazardous chemical management.

This invention relates to the field of hazardous chemical management technology, and provides a hazardous chemical violation early warning system based on image feature comparison. The system includes a real-time image acquisition module, a multi-dimensional feature extraction module, a violation scenario rule base module, a real-time image feature comparison module, and a linkage early warning triggering module. This invention utilizes deep learning networks to extract multi-dimensional features such as personnel protective attire, chemical properties, and the spatiotemporal trajectory of operational behaviors. Through real-time dynamic comparison with a preset violation scenario model, it achieves accurate identification of violations such as single-person operation, lack of protective equipment, mixing of incompatible chemicals, and dangerous dumping actions. The system combines edge computing and cloud-based big data analysis, supporting incremental fine-tuning of model weights and hierarchical early warning linkage. This invention effectively solves the problems of numerous blind spots in manual supervision and the difficulty in detecting hidden violations, significantly improving the proactive prevention capabilities and intelligent supervision level of hazardous chemical operations.

This invention relates to the field of hazardous chemical management technology, and provides a Weizhiheng intelligent weighing and big data comparison and early warning system for hazardous chemicals. The system includes modules for multi-dimensional time-series data acquisition, nonlinear physical loss compensation, dynamic tolerance generation based on operator profiles, and multi-dimensional verification and interlocking early warning. By collecting ambient temperature and humidity data and time spent away from the container, combined with saturated vapor pressure and viscosity coefficient, the system calculates and separates dynamic volatilization and wall residue losses to obtain the compensated actual operational consumption. A deep learning model adaptively adjusts the allowable consumption range based on the operator's historical variance characteristics. When consumption exceeds the limit, a visual perception front-end is activated to identify physical spillage characteristics. This invention eliminates the interference of environmental and physical factors on weight calculation, achieves accurate identification of non-malicious losses and illegal interception, and significantly improves the accuracy of safety control over the flow of hazardous chemicals.

This invention relates to the field of hazardous chemical management technology, providing a hazardous chemical spectral analysis system and control method to prevent substitution. The system includes a basic information and physical quantity acquisition module, a dynamic adaptive spectral detection module, and a central control server. The system utilizes zoom control to acquire first background spectral data focused on the outer wall of the container and second mixed spectral data focused on the internal liquid. A differential feature extraction algorithm is used to remove interference from the container material, generating pure reagent spectral feature data and establishing a baseline profile. During verification, the server calculates the weight change difference before and after return, along with spectral similarity values, and performs calibration for natural drift using an environmental attenuation compensation model. A multi-dimensional data anti-counterfeiting judgment model is then used to output a safety control signal. This invention achieves non-destructive verification of component authenticity, effectively solving the problem of identifying malicious substitution by equal weight and deterioration contamination.
