The application discloses a construction safety hidden danger detection method and system based on a multi-modal large language model, which comprises the following steps: adopting a streaming multi-modal data acquisition strategy to synchronously collect text logs, image streams and sensor data of a construction site in real time; using an edge computing device to perform parallel preprocessing on real-time multi-modal construction safety data streams to eliminate inter-modal time inconsistency; constructing a multi-modal data feature correlation graph to identify and repair modal data anomalies caused by environmental interference in real time; performing real-time feature extraction and fusion on the preprocessed data streams, and completing rapid coding and identification of cross-modal hidden danger features through a sliding window mechanism and attention weight dynamic adjustment; based on the real-time feature fusion result, performing instant analysis through an online hidden danger detection method; and according to the real-time detection result, completing real-time visualization and tracking of the hidden danger, thereby achieving timely early warning and tracking management of the hidden danger.

The utility model discloses an air reservoir fast-plug C-shaped ring detection device which comprises a material placing tool, a clamping mechanism and a conveying line, the clamping mechanism and the conveying line are arranged on the outer side of the material placing tool, and a horizontal camera horizontally connected to the upper end of the conveying line in a butt joint mode and a vertical camera vertically connected to the upper end of the conveying line in a butt joint mode are further fixedly installed at the position close to the conveying line. A defective product box and a display screen are further fixedly arranged near the conveying line, and a non-defective product baffle in butt joint with the upper end of the conveying line is further fixedly installed on the outer side, close to the tail end, of the conveying line. The utility model provides a detection device which can automatically clamp a product and place the product at a designated position through a clamping mechanism, can detect the defects of a quick-plug C-shaped ring of an air cylinder through automatic photographing of a camera, can continuously detect a plurality of products, and can effectively avoid detection omission caused by fatigue of manual detection compared with traditional manual detection, so that the detection efficiency is improved. And the detection accuracy is effectively improved.

This invention provides a defect detection device for automotive injection molded parts processing, relating to the field of automotive injection molded parts inspection technology. It includes: a positioning frame with a fixing plate mounted on its rear side; a servo motor mounted on the outer side of the fixing ring, with a gear mounted on the output end of the servo motor; a guide block slidably mounted on the inner side of the guide rail; and a high-brightness lamp and a displacement sensor mounted on the bottom of the guide block. The high-brightness lamp below the guide block moves omnidirectionally and fully covers the injection molded part. Combined with the synchronous movement of the inspection tray, it ensures that light can fully illuminate all parts of the injection molded part, especially allowing light to pass through and display gaps and defects. This provides clear lighting conditions for defect detection, ensuring the inspection quality of automotive injection molded parts and solving the problem that small defect areas such as gaps on some automotive injection molded parts become blind spots during inspection.

The utility model relates to the related technical field of welding quality detection, and one embodiment of the utility model provides a welding quality detection device of a pipe welder, which comprises a bottom frame and a platform, the platform is fixed on the bottom frame, detection display equipment is arranged at the bottom and the outer side of the platform, a detection head is arranged on the platform, a rolling detection assembly is arranged on the platform, and the rolling detection assembly is arranged on the platform. The support moving assembly is arranged on the platform, the rolling detection assembly comprises a support, the support is fixed on the surface of the platform, the bottom of the platform is provided with a first cylinder, the output end of the first cylinder is connected with a side frame, the top of the support is provided with a groove, the detection head is installed in the groove, and the side end face of the side frame is rotatably connected with a driving wheel. By means of the technical scheme, the technical problems that in the prior art, it is difficult for detection personnel to guarantee that the whole welding opening can be accurately covered by the moving path each time, omission is prone to occurring, and consequently part of positions cannot be detected are solved.

This disclosure relates to an obstacle detection method, apparatus, vehicle, storage medium, and program product. The obstacle detection method includes: acquiring a target point cloud of a region surrounding a vehicle detected by an onboard environmental sensor; determining multiple types of grids by performing grid projection on the target point cloud, wherein each type of grid includes a projected point cloud corresponding to the target point cloud, and each type of grid uses a different grid unit division method; and determining target obstacle information based on the projected point clouds included in each type of grid. This technical solution can avoid the problem of missed obstacle detection and improve the accuracy of obstacle detection.
