This application discloses an NFC double-sided trace parallel connection structure, belonging to the field of near-field communication applications. The NFC double-sided trace parallel connection structure effectively reduces the overall antenna DCR, thereby reducing energy loss during signal transmission. The NFC module consumes less power during operation, helping to extend the device's battery life and making communication between the NFC device and external reading / writing devices more stable and efficient, improving data transmission speed and accuracy. The lower resistance enhances the antenna's sensing capability, increasing the effective sensing distance between the NFC device and other devices, making operation more convenient and flexible for users. Furthermore, the improved signal transmission enhances the compatibility of the NFC device with various types and brands of reading / writing devices, ensuring normal operation in more scenarios. In addition, the antenna thickness under this structure is not significantly different from that of conventional double-sided boards, thus requiring no special antenna space and exhibiting good applicability in practical applications.

This application relates to a detection system for the proximity of a boom to a high-voltage power line on an engineering machinery unit. The engineering machinery includes a boom, which comprises multiple boom sections. The detection system includes a high-voltage power line detection component and a controller. The high-voltage power line detection component is mounted on at least one boom section and is an antenna extending along the length of the boom section. Each boom section's corresponding high-voltage power line detection component is connected to the controller. The technical solution of this application designs the high-voltage power line detection component as an antenna extending along the length of the boom section, using a detection surface instead of a detection point, thereby improving the sensing capability for high-voltage power lines and ensuring that the protection range covers the entire boom section. Furthermore, when high-voltage power line detection components are simultaneously mounted on multiple boom sections, interference between the high-voltage power line detection components and the boom section structure can be reduced or avoided.

This invention relates to the field of gearbox condition detection technology, specifically to a detection device and method for multi-stage gearboxes with transmission stability. The device includes a fault feature extraction component as the core of an intelligent sensor. The fault feature extraction component comprises an insulating carrier, a signal pickup coil wound on the insulating carrier, and an upstream detection sensitivity gain unit. The detection sensitivity gain unit has a rectifier channel that constrains dispersed wear products to the insulating carrier. An adaptive stabilizer is arranged around the fault feature extraction component to form a flow bypass. The adaptive stabilizer performs axial compensation displacement in response to fluid pressure fluctuations in the monitoring environment. This invention utilizes fluid acceleration and inertial sorting. When the sleeve pressure senses and opens the bypass to drain oil, the inertial difference propels high-momentum abrasive particles into the central detection area, thereby achieving oil bypass but not abrasive particle bypass, ensuring accurate capture of weak fault features under all operating conditions.

The frame unit is connected to a steering mechanism, which includes a steering handle. The body cover unit includes at least a steering handle cover covering the steering handle and a maintenance cover located in front of the steering mechanism. A keyless controller is installed on the frame unit, along with a long-range antenna and a short-range antenna electrically connected to the keyless controller. The keyless controller and the long-range antenna are housed within the maintenance cover. This improves the usability of the all-terrain vehicle and facilitates maintenance of the keyless controller and the long-range antenna by housing them within the maintenance cover.

This invention provides a dynamic mechanical structure wind vane ground-mounted landscape tower, relating to the field of communication landscape towers. It includes a landscape column, a flipping guide rod, a marker head, a marker tail, and an extension plate. The landscape column has two annular sub-tower structures on its upper and lower sides of its outer end face, symmetrically positioned. The landscape column's outer end face has four outward-facing adjustment cavities. This design uses a threaded connection to move a telescopic connecting cylinder outward, which in turn moves the connecting guide plate, and then, through transmission, moves the directional marker outward. As the directional marker moves outward, it makes it easier for pedestrians to understand the wind direction, providing a direct visual representation of the wind's direction. This design also deforms the extension plate, increasing the wind-receiving area of ​​the marker tail, thereby expanding the wind-sensing area and improving the wind vane's sensing accuracy. This facilitates adjustment and sensing of the wind direction angle, and the change in the dynamic mechanical structure enhances the wind vane's sensing effect.
