This invention relates to a stepped layout structure for a megawatt-class energy storage power station in mountainous terrain. Belonging to the field of energy storage power station engineering layout, it aims to solve the technical problems of traditional mountain energy storage power stations, such as the need for large-scale site leveling, large earthwork volume, high cost, severe ecological damage, and inconvenient operation and maintenance. The invention features a multi-level stepped platform along the mountainside, with adjacent platforms connected by slope transitions. Energy storage units are arranged on the platforms, and maintenance roads are provided on the slope surfaces. The platform consists of a three-level energy storage area and an independent booster area platform. The energy storage units are arranged in an array, with battery energy storage compartments and PCS booster units arranged centrally or staggered. The battery energy storage compartments are located on a foundation, which is fixedly connected to a firewall. The station area is equipped with a ring-shaped fire access road, cable trenches, ancillary facilities, and slope inspection steps. This invention significantly reduces earthwork excavation and filling, improves land utilization, offers structural stability, convenient operation and maintenance, and high safety and reliability, significantly reducing construction costs and making it suitable for the construction of megawatt-class large-capacity energy storage power stations in mountainous terrain.

This invention relates to the field of mining operations, specifically a real-time simulation and optimization system for mine construction progress based on digital twins. The system includes an edge-side multimodal perception module, an edge-side preprocessing and micro-control module, a cloud-based digital base and model reconstruction module, a macro-level progress prediction and optimization module, and a twin sandbox and safety execution module. The system edge synchronously collects physical environment and equipment operating parameters. The data is then processed by an edge computing gateway through factor graph fusion, noise reduction, and dimensionality reduction before being transmitted to the cloud. The cloud center dynamically corrects the three-dimensional geological attribute layer using a Bayesian inference algorithm based on the underlying mechanical feedback data from the equipment, and simultaneously generates a real-time excavation comparison model using a semantic segmentation network. A multi-agent simulator predicts construction probabilities and generates a global scheduling strategy. The generated control strategy must completely penetrate a three-level locked firewall, including virtual collision avoidance verification, before being converted and distributed to the underlying electromechanical actuators. This achieves low-latency interaction even under extremely weak network conditions.

This application provides a biometric-based emergency passage control system for fire-resistant curtain walls, relating to the field of building fire safety technology. It performs time-stamp synchronization and alignment, and multispectral spatial coordinate registration on multi-source sensor data. Subsequently, it quantifies and evaluates smoke concentration and ambient temperature to obtain an environmental noise index. Based on this index, it performs adaptive defogging reconstruction and contrast enhancement on visual feature regions to extract refined feature vectors. In the modal fusion stage, the system dynamically allocates the weights of each modality. It solves the high false rejection rate problem caused by feature distortion in fire environments through feature uncertainty quantification and nonlinear kernel mapping similarity reconstruction, and introduces cross-modal consistency calibration penalty logic to address the risk of false matches caused by environmental interference. Finally, it dynamically adjusts the decision threshold based on the environmental noise index, and drives the fire-resistant curtain wall's electrically controlled push rod in conjunction with the fire alarm trigger signal, ensuring reliable opening of escape routes while maintaining the tightness of access control in safe areas.
