The utility model discloses a kind of semitrailer tarpaulin devices, comprising: semitrailer floor, the top of the semitrailer floor is fixedly connected with vertical plate, the top of the vertical plate is fixedly connected with top plate, the top of the semitrailer floor is fixedly connected with the side of head baffle;Top shielding component, the top of the head baffle is fixedly connected with the side of top shielding component, side shielding component, the side of the vertical plate is fixedly connected with the side of side shielding component, the tail shielding component is used to adopt tarpaulin shielding to the tail of semitrailer, the utility model relates to tarpaulin device technical field.The semitrailer tarpaulin device, by the setting of top shielding component, by driving motor directly driving threaded block drives the rotation axis of far end to move outward, first tarpaulin is spread over the top of entire semitrailer, and first tarpaulin is carried by multiple rotation axes, can evenly share tarpaulin quality, avoid causing equipment overload in moving process.

This invention provides a multi-source fusion-based system and method for calculating peak fatigue levels in runners of up to 10,000 users. The system includes a data acquisition module, a data preprocessing and fusion module, a peak fatigue calculation module, a safety early warning and coordinated intervention module, a data security and privacy protection module, and a backup data acquisition unit. The core functionality involves collecting five-dimensional, multi-source, safety-related data on runners' physiological, exercise, environmental, individual, and subjective factors through the data acquisition module. A simplified version of non-invasive electromyography (EMG) signals is introduced to identify latent muscle fatigue. A dual-layer fusion architecture of "edge + cloud" is adopted, combined with a federated learning model, to achieve deep fusion of multi-source data while protecting runner privacy, constructing a personalized dynamic fatigue threshold model. The system calculates peak fatigue levels based on a real-time safety-oriented fatigue index, implements closed-loop intervention through a four-level graded early warning mechanism linking multiple terminals, and ensures data security through three-link redundant transmission, data anonymization and encryption. The backup acquisition unit ensures full coverage of data from up to 10,000 users.
