The first aspect of the present application discloses a ship longitudinal bending strength checking method based on component classification and data linkage. The second aspect of the present application discloses a ship longitudinal bending strength checking system for implementing the above ship longitudinal bending strength checking method. The core of the present application is to build an efficient and accurate checking system by scientific component classification and close data linkage, and to deeply couple the professional ship strength checking logic and the data processing capability of the general electronic spreadsheet. The system is based on a unique component numbering system divided according to the plate rack position, combined with the pre-existing double classification of components, to realize the fine management of the ship longitudinal bending strength checking process. At the same time, the system developed based on the Excel platform solidifies the complex checking process into an orderly associated calculation table, ensuring the automatic transmission and efficient processing of data.

The application discloses a method for reducing the loss of large dynamic FFT operation by truncation and number system conversion, and relates to the field of radar signal processing. Firstly, by selecting appropriate rotation factor quantization bits and complex multiplication truncation bits, the full frequency domain precision loss is ensured to be not more than a fixed value under the condition of small signal input; then, whether to retain the bit width increased by complex addition operation is judged according to the order corresponding to the number of FFT points required to be operated; finally, according to the operation bit width truncation rule, after completing the entire FFT operation, the FFT operation result represented by fixed-point numbers is converted into the FFT operation result represented by floating-point numbers. The application can effectively retain the spectrum information under the condition of small signal input, avoid the signal distortion caused by the truncation in the FFT processing process, greatly improve the dynamic range, and provide good data support for subsequent fine processing.

A robotic control system may be configured to translate a first set of location coordinates based on a first location numbering system to a second set of location coordinates based on a unified location numbering system. A robotic control system may receive layout data of a warehouse, the layout data containing a plurality of location coordinates of racks and storage locations. The location coordinates may be of a first format based on the first location numbering system that is specific to the warehouse. The robotic control system may analyze the format of the location coordinates to select, from a plurality of candidate conversion algorithms, a suitable conversion algorithm to translate the plurality of location coordinates of the first format to a second format based on the unified numbering system. The robotic control system may store the translated location coordinates for use in generating a topometric map of the warehouse.

This invention relates to the field of big data processing technology, specifically to a lighting data processing method and system based on environmental perception. The method includes the following steps: acquiring brightness and time series data and dividing them into segments by intervals; extracting segment numbers to identify the direction of change; matching segments with time windows to determine their type and associate them with paths; verifying segment consistency according to path order; and correcting the order by matching timestamps. In this invention, by dividing adjacent time intervals in the time series and constructing a segment numbering system, brightness changes exhibit continuous characteristics. Path relationships are extracted by combining changes in segment number direction, and segment cross-mapping is established within multiple time windows to form an association analysis of the brightness evolution process. Connection verification is performed based on segment type and path order to ensure consistency of adjacent data changes. Combined with time position matching and order correction, the lighting state changes become more stable, improving response reliability under lighting conditions and suppressing the impact of abnormal disturbances.
