This invention discloses an intelligent goods delivery route optimization method, relating to the field of intelligent logistics and delivery technology. The method comprises the following components: S1, metaverse space construction; S2, user role creation and access; S3, immersive collaborative route planning; and S4, route optimization algorithm and data-driven approach. By constructing a logistics and delivery metaverse space, this invention achieves real-time synchronization between the real world and the virtual space, including synchronized updates of order information, vehicle location, and traffic conditions. This helps logistics dispatchers perform more accurate route planning in the virtual environment. Delivery personnel can also view and provide feedback on route planning schemes through virtual roles before executing tasks, thereby achieving multi-party collaborative immersive route planning. This method can significantly improve the efficiency and accuracy of goods delivery, reducing delivery delays or errors caused by information asymmetry or poor communication.

This invention discloses a method and system for anomaly identification in multi-source monitoring data of steel structures, belonging to the field of steel structure monitoring data processing technology. The method includes acquiring multi-source monitoring data of steel structures and unifying time-scale alignment, generating a preprocessed dataset containing working condition features and quality markers. Based on the working condition features, the physical baseline prediction value is calculated; based on the preprocessed dataset, the data baseline prediction value is calculated, and dual residuals are obtained. The physical residual strength is calculated based on the dual residuals; and the residual inconsistency degree and sliding window adaptive threshold are calculated to output anomalies. This invention constructs a stable input through unified time-scale and quality marker constraints, generates physical and data dual baselines in parallel, and outputs dual residuals. Online discrimination is completed using correlation robustness strength + residual divergence adaptive weight + sliding window threshold, achieving an interpretable, traceable, and more robust anomaly identification process for long-term monitoring under working condition drift.

This invention belongs to the field of elevator light curtain technology and discloses an elevator light curtain with door opening and closing warning function. It includes a light curtain housing and positioning frames fixed at both ends. A groove is formed on the left side of the light curtain housing, and the light curtain body is connected inside the groove. Warning LEDs are installed on both sides of the light curtain body. A movable frame is fitted around the outside of the light curtain body. Limiting grooves are formed on the front and rear sides of the light curtain housing, and the movable frame slides in cooperation with the limiting grooves. This elevator light curtain with door opening and closing warning function completely changes the traditional "passive response" safety protection mode of light curtains through the design of multiple arrays of dual-color warning LEDs, constructing an active and efficient warning system. During the elevator door closing process, the high brightness and wide warning range of the dual-color flashing lights can clearly remind the elderly and children who move slowly, and can also effectively attract the attention of passengers focused on electronic devices, avoiding collisions or pinching accidents caused by delayed reaction.

This invention relates to the field of unmanned aerial vehicle (UAV) inspection technology, specifically to an augmented reality-based UAV inspection platform and method for airport airspace. The platform comprises interconnected server modules, a GIS engine module, a UAV module, a flight control and interaction module, a data interface module, a business management module, and a UAV application module. By utilizing augmented reality technology to provide intuitive information overlay and precise guidance for UAV inspections, it achieves efficient and comprehensive inspection of airport airspace and possesses the ability to proactively handle intrusion targets such as unauthorized UAVs. This effectively solves the problems of low efficiency and incomplete coverage in traditional manual inspections, insufficient accuracy and poor real-time performance of remote sensing monitoring methods, high costs of long-term periodic updates, and passive defense against intrusion targets such as unauthorized UAVs.

This application discloses an odor-proof main structure and a cat litter box, relating to the field of pet product technology. The odor-proof main structure includes a litter bin and a base. The litter bin is rotatably mounted on the top of the base. The top of the base has a recessed cavity into which the bottom of the litter bin extends. A uniform rotational gap is formed between the inner wall of the recessed cavity and the litter bin. A collection port is located at the bottom of the recessed cavity. A sealing ring is installed at the bottom of the litter bin. The sealing ring is in sealed contact with the inner wall of the recessed cavity. When the litter bin is in its initial position, the projection outline of the sealing ring on the ground is outside the projection outline of the collection port on the ground. This odor-proof main structure effectively prevents odors from escaping from the litter bin, effectively reduces noise, and maintains a simple structure, facilitating disassembly and cleaning.

The application provides an electrical layer fault time determination method adopting multi-value discriminant comparison, and is used for a height measurement system adopting four kinds of measurement devices, namely, inertial components, radio altimeter, diaphragm capsule barometric altimeter and GPS height measurement device, for redundancy fusion measurement; four kinds of signals, namely, inertial height, radio height, diaphragm capsule barometric height and GPS height, are respectively subjected to nonlinear filtering transformation, and then four kinds of filtering speed signals and filtering signals are obtained; the inertial components are independently measured, the interference probability is small, therefore, the relative error data and the absolute error data are obtained by comparing the latter three with the inertial components; the threshold valve is set to judge the time when the fault occurs, and the component causing the fault is further judged according to the mutation of the filtering speed signal; the method has the advantages of accurate judgment and simple implementation.
