6results about How to "Stable and efficient transmission" patented technology

This invention discloses a remote online teaching method and system based on internet education, including a teaching server, a student terminal, and a teacher terminal. This remote online teaching system leverages the multi-channel transmission characteristics of the internet, dividing a single class into multiple learning groups. Each learning group shares a communication channel, allowing for multi-channel communication with the instructor. This effectively reduces communication congestion, resulting in more stable and efficient video transmission. Group members can communicate with each other, facilitating peer interaction. Instructors can individually enter each learning group during communication sessions to provide guidance. The system incorporates an evaluation unit, allowing for peer evaluation between instructors and students, monitoring and regulating student learning behavior. The system collects evaluations through multiple channels and at multiple levels, providing a comprehensive assessment that promotes better teacher-student communication and improves teaching quality.

This utility model relates to the technical field of servo motor transfer mechanisms, and discloses a synchronous belt tension adjusting wheel for a servo motor transfer mechanism. It includes a base, a motor body fixedly connected inside the base, a drive wheel fixedly mounted at the output end of the motor body, a synchronous belt body meshing with the teeth of the drive wheel, a tension wheel meshing with the teeth of the synchronous belt body, a support frame rotatably connected inside the tension wheel, a fixed box slidably connected to the outer wall of the support frame, a lead screw rotatably connected inside the fixed box, a disc fixedly connected to the top of the lead screw, and a limit rod slidably connected inside the disc.

This invention provides a data synchronization acquisition system and method for suspended tunnel experiments. The system employs a 10-gigabit fiber optic network, which includes a network layer, a software control layer, and an acquisition layer. The network layer includes 10-gigabit fiber optic cables, 10-gigabit switches, and fiber optic network interface cards (NICs). The software control layer includes a synchronization control terminal, a data server, acquisition clients, and a large display screen. The acquisition layer includes various sensors and lower-level machines installed in the suspended tunnel mechanism test environment. The synchronization control terminal sends data acquisition commands to the acquisition clients. The acquisition clients, upon receiving acquisition commands, send commands to the lower-level machines or sensors and provide feedback on the latest acquired data via the 10-gigabit NIC. Furthermore, the system is used to transmit the acquired data to the data server in real time and to synchronously transmit real-time image signals from the system to the large display screen. This improves the efficiency and stability of network transmission, providing fundamental support for synchronous acquisition control and real-time data storage.
