The present application discloses a vehicle tire detection device, including a TPMS (Tire Pressure Monitoring System) sensor, an antenna matching network, and a terminal antenna. The TPMS sensor uses ASK / OOK / FSK transmission technology with a data transmission rate greater than 20kbps. The TPMS sensor is connected to the terminal antenna through the antenna matching network. The terminal antenna is one of a valve stem, a metal base, or a tire rim. In the present application, by enhancing a radio frequency data transmission rate, an aim is to reduce a radio frequency transmission time of the sensor, thereby reducing a transmission power consumption. By shortening the transmission data time, an aim is to enhance a signal transmission penetration and improve a radio frequency anti-interference capability. Using a valve stem, metal base, or tire rim as the terminal antenna enhances a length and area of the antenna, leading to higher signal conversion efficiency and better transmission stability of the sensor on the vehicle. The terminal antenna being on the outside of the tire body is beneficial for increasing the strength of the wireless signal, with the same transmission power of the TPMS sensor, it is easier to achieve wireless communication over a longer distance, and the error rate is reduced.

This invention discloses a high-speed network communication optical disc library and a data reading and storage method, including a main control unit, a Blu-ray drive assembly, an optical disc cartridge transfer device, and a disc splitting device. The main control unit coordinates the components through a system control module to perform optical disc reading, writing, transfer, and sorting. Its data conversion module processes the data stream read and written by the optical drive assembly, completes the conversion, verification, and protocol encapsulation / decapsulation of SATA format data, and communicates with the user terminal via high-speed Ethernet. The Blu-ray drive assembly includes multiple optical drive units with dual optical heads and dual SATA interfaces, enabling parallel reading and writing of single optical discs. The optical disc cartridge transfer device is responsible for optical disc transportation and information feedback, and the disc splitting device distributes optical discs to each optical drive or removes them for storage according to instructions. This invention removes the limitations of transmission distance and geographical location from the data storage system, reduces the transmission latency of user terminal instructions, improves the system's response speed to client instructions, increases the data transmission rate, and improves the reliability of each node in the system.

This invention discloses a multi-channel light-slice microscopic imaging device. The image acquisition module includes multiple image detectors. A laser array emits multiple excitation beams of different wavelengths, which are then combined into a single incident beam by an optical path module. This incident beam passes through a scanning galvanometer and an imaging module before illuminating the sample on a stage mounted on a three-dimensional displacement platform. The imaging objective in the imaging module collects fluorescence signals from the sample, which are then split by the beam-splitting module to form multiple fluorescence signals of different wavelengths and projected onto the multiple image detectors. Each image detector forms an image imaging channel. Multiple image imaging channels receive multiple fluorescence signals of different wavelengths and transmit them to the corresponding image detectors. The three-dimensional displacement platform enables three-dimensional displacement movement of the sample slice. By employing a strategy of continuous motion imaging of the sample slice and simultaneous detection and acquisition of fluorescence signals by multiple image detectors, the time interval between sample preparation and imaging, as well as the pauses during imaging, can be reduced.
