This invention relates to the fields of computer vision and artificial intelligence, specifically to a knowledge-guided meter reading method and system based on a large visual language model. The method includes: a template acquisition step: acquiring a meter image and retrieving a structured reading prompt template containing metadata and inference logic instructions based on the type; a multimodal input step: inputting the image and template as multimodal data into a large visual language model; an inference generation step: extracting visual features and aligning them with the template's attention, executing thought chain inference in response to instructions, and generating a natural language description result containing intermediate inference evidence; and a parsing output step: performing structured parsing on the result and extracting meter reading values ​​that conform to format constraints. This invention achieves a deep integration of business logic and visual perception, establishes human-computer trust, and avoids logical fallacies inherent in purely visual models.

This invention discloses a testing platform for atomizer testing in a new energy vehicle painting production line, relating to the field of new energy vehicle production technology. It includes a workbench and a first testing component. A support plate is mounted on the top of the workbench, and a positioning component is connected to the top of the support plate. The first testing component is positioned above the workbench and includes a testing box. A fixing rod is mounted on the lower inner side of the testing box, and a return spring is sleeved on the outer side of the fixing rod. This invention uses the positioning component to automatically center and securely clamp the atomizer under test, ensuring a consistent testing benchmark. Simultaneously, it employs a purely mechanical transmission and amplification mechanism to amplify and convert the minute radial or axial movement of the rotating cup caused by bearing wear into a significant displacement of the indicator block. The wear condition can be intuitively and quickly determined through the scale on the observation window. Furthermore, this testing method eliminates the need to disassemble the atomizer, avoiding damage during disassembly and assembly.

The application discloses a kind of unmanned plane meteorological data measurement and processing method, belong to meteorological detection and unmanned plane application technical field.The method is aimed at the problem that the measurement is inaccurate due to the dynamic interference of unmanned plane platform itself, by real-time acquisition unmanned plane's attitude, speed, rotor speed and installation parameter, the original wind speed and direction data are carried out dynamic compensation calculation based on polynomial model;At the same time, the dual-redundancy sensor data are fused and fault judged, and a lightweight AI model is introduced for real-time anomaly detection.All steps are executed in parallel on the FreeRTOS real-time operating system.The application effectively decouples the coupling interference of unmanned plane platform on meteorological measurement, significantly improves the measurement accuracy and data reliability, and realizes high-precision meteorological observation comparable to fixed station in complex flight environment.
