This utility model discloses a full-color LED large-screen display device, relating to the field of LED large screens. It includes an outer frame, with a display screen mounted on the front side of the frame. A mesh is installed at the bottom of the through-space of the outer frame, and a motor is installed above the mesh. A fan is connected to the output end of the motor. Air ducts are symmetrically arranged inside the outer frame, with air holes evenly spaced on both sides of the ducts. Heat-absorbing blocks are evenly spaced through the left and right sides of the outer frame, with through holes in the center of each block. Heat dissipation fins for auxiliary heat dissipation are evenly spaced on the back of the outer frame. During use, this full-color LED large-screen display device can evenly deliver air into the interior space of the large screen, and the internal heat is carried out to the outside through even airflow. Simultaneously, the heat-absorbing and guiding elements on the sides and the heat-absorbing and heat-dissipating components on the back can accelerate heat dissipation, thereby improving heat dissipation efficiency, extending the lifespan of the large screen, and preventing heat damage.

This invention provides a bus filtering method for calibration, implemented on a bus filtering device used in calibration. One end of the bus filtering device is connected to the vehicle's CAN bus, and the other end is connected to a calibration device and a CAN controller. The method includes the following steps: detecting whether a calibration message generated by the calibration device during calibration of the CAN controller is received; if a calibration message is detected, forwarding the calibration message only to the CAN controller and blocking the forwarding of the calibration message to the vehicle's CAN bus. Implementing this invention can improve the situation of calibration message loss or untimely response during vehicle calibration, thereby improving calibration efficiency.

The utility model relates to the technical field of hat and coat stand forming pre -cutting technology discloses a hat and coat stand forming pre -cutting edge mould, including roof, the roof top fixed connection has hydraulic lock, the bottom of hydraulic lock is inserted and is connected with the mouth. The hat and coat stand forming pre -cutting edge mould, through the setting of dismounting mechanism, when installing and replacing the cutter main part, only need to make the mouth of cutter main part top insert the end of hydraulic lock, make the limiting hole alignment, then, the power of one side is connected, make the magnetic force of mouth place, and the suction of one side bolt is produced, the bolt is affected by the magnetic force and can penetrate the inside of limiting hole, disconnect the power, the electromagnet loses the magnetic force, the bolt of one side is supported by the reverse force provided by the spring and returns to the starting position, thereby realize the effect that the cutter main part of hydraulic lock and bottom are quickly installed and disassembled, need not install through bolt, improved the installation efficiency of equipment.

This invention relates to a method for detecting surface defects in hot-rolled strip steel for industrial applications. First, an open-source defect dataset is acquired and preprocessed, and the model's runtime environment is configured. Second, the original target detection model structure is improved: a Hybrid Attention Fusion (HAF) module is embedded after the convolutional layers of the backbone feature extraction network to enhance non-local feature modeling capabilities; a Spatial Guided Downsampling (SGDown) module is designed to replace the traditional convolutional downsampling structure to reduce the loss of detailed information; and a Multi-Branch Fusion (MBF) module is constructed in the neck network to reduce the model's false negative rate. Then, the improved network model is trained and hyperparameters are optimized to obtain the optimal defect detection model. Finally, the trained model is deployed in a detection system for real-time detection of surface defects in hot-rolled strip steel. This invention reduces the computational complexity of the model while maintaining detection accuracy, and possesses good real-time performance and engineering application value.
