The utility model discloses a battery pack thermal runaway derived disaster control system. The system includes an eruption handling device including a fire retardant catalytic section. The flame-retardant catalytic section comprises a retarding filler with a plurality of retarding pore channels, the diameter of the pore channels is smaller than the maximum experimental safety gap of combustible gas, and a radially protruding retarding locking piece is arranged on the shell or the retarding filler; the blocking and urging filler or the shell is provided with a blocking and urging locking channel and a blocking and urging clamping groove, wherein the blocking and urging locking channel corresponds to the blocking and urging locking piece and is used for the blocking and urging locking piece to slide in and assemble in the axial direction, and the blocking and urging clamping groove is used for clamping and fixing the blocking and urging locking piece. The utility model aims to avoid and delay the occurrence of derivative disasters when the battery pack is in thermal runaway, and reduce the influence and loss of the derivative disasters.

This application provides a method and system for managing construction site accident hazards based on the Industrial Internet of Things (IIoT), relating to the field of IIoT technology. The method includes: determining a set of key hazard management characteristic parameters; determining a preset risk assessment threshold that meets the requirements of the construction industry; configuring a correction coefficient for the preset risk assessment threshold based on factors such as workload intensity, equipment aging, and the accumulation trend of site hazards, and setting a dynamic constraint mechanism for hazards in conjunction with the set of key hazard management characteristic parameters; and simultaneously verifying the accident hazard investigation and analysis parameters based on the dynamic constraint mechanism and the on-site safety intervention mechanism, outputting a construction site accident hazard control strategy. This application solves the technical problem in existing technologies where static and isolated hazard assessment standards are severely out of sync with the dynamic and complex working conditions of construction sites, leading to untimely hazard identification and further affecting the efficiency of accident hazard control. It achieves timely hazard identification and improves the efficiency of accident hazard control.

The invention belongs to the technical field of production safety prevention and control, and particularly relates to a mine production potential safety hazard control method and device and electronic equipment. According to the scheme, dynamic simulation and prediction of a risk spatio-temporal evolution rule are achieved by constructing a spatio-temporal-behavior coupling risk field model; a dominant risk type is accurately judged by means of mode recognition based on deep learning, optimal scheduling of hidden danger points is carried out based on a multi-resource collaborative scheduling strategy, and finally continuous adaptive optimization of model parameters is realized by disposing feedback data closed loop. A closed-loop control system from accurate early warning and intelligent diagnosis to optimized disposal and self-evolution is constructed, and the core pain point problems of isolated early warning, single mode recognition, experience-dependent decision making and the like existing in current mine safety production hidden danger control are effectively solved.

This invention relates to the field of construction management technology, specifically disclosing an integrated electromechanical cage construction management system. This system addresses existing problems such as reliance on experience and verbal instructions for cage unloading, difficulty in accurately selecting and stably arranging construction methods under multiple constraints, disconnect between load limits and loading lists, lack of linkage between tower crane torque and wind speed, frequent conflicts between path and fall radius, and difficulty in tracing responsibility due to scattered documentation and images. The system includes a data acquisition layer, a construction method selection module, a closed-loop verification module, a scheduling and warning module, a crane risk control and access control module, and an evidence collection and archiving module. This invention unifies multi-source data such as tower crane amplitude—lifting weight, load, and wind speed—into a constraint set, driving the feasibility and prohibition determination of three construction methods and coordinate-based layout. It implements consistent verification of loading lists, amplitude curves, and categorized load limits, generates attitude timestamp scheduling and fall radius occupancy plans, and links non-unhooking risk control and access control with evidence chain archiving, achieving pre-hazard control, process control, and post-event traceability.
