The invention discloses a device and method suitable for MICP repairing of a curved surface crack of a PHC pipe pile, and belongs to the technical field of concrete crack repairing. Comprising a mobile platform, the mobile platform is provided with a double-liquid grouting pump, an intelligent control system, a heat preservation bacteria liquid barrel and a cementing liquid barrel, the heat preservation bacteria liquid barrel and the cementing liquid barrel are connected with the double-liquid grouting pump through pipelines, the double-liquid grouting pump is in communication connection with the intelligent control system, and a waste liquid barrel is further arranged in the mobile platform; the intelligent control system cooperates with the double-liquid grouting pump, so that the grouting time and the variety and proportion of bacterial liquid and cementing liquid can be accurately controlled, and a differentiated repair strategy is implemented according to the crack width; and the transparent plate body allows an operator to visually observe the filling of the crack, the permeation of the zeolite particles and the MICP cementing process in real time, so that the repair quality and the effect are controllable. The method has no negative influence on the environment; the required bacterial liquid and cementing liquid are relatively low in material cost, and compared with a traditional remediation method, the method has the remarkable advantages of environmental protection, economy and high efficiency.

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.

The invention provides a data lake table concurrent writing method and device, and belongs to the technical field of computers.The method comprises the steps that writing channels are dynamically selected according to the number of active writers of a target partition; for a write-in request entering a controlled concurrent write-in channel, the version number of a current partition is obtained firstly, data is written into a temporary storage area marked with the version number and a timestamp, and then the version number is tried to be increased progressively through atomic comparison exchange operation to submit the data; if the atomic comparison exchange operation fails, triggering an automatic retry mechanism, if retry succeeds, marking the corresponding data as a mergeable state, and if retry fails, transferring the data into an asynchronous repair channel; and dynamically triggering a merging task according to the number of the temporary files and a system load index, merging data in the temporary files according to a version number sequence, and atomically updating a main data version. According to the method, the problem of data consistency of single-partition concurrent writing is solved, and automatic switching and zero manual intervention of a dynamic routing mechanism can be realized.

The application discloses a kind of real-time semantic segmentation method and system based on multi-resolution branch, it is related to graphics processing technical field.By obtaining image data, using depth multi-resolution network to carry out semantic segmentation to image data, obtain semantic segmentation feature map;Wherein, semantic segmentation process includes: to image data is carried out convolution feature extraction, obtains the spatial information and semantic information of image;Using different resolution branch network to the spatial information and semantic information of image respectively learns to obtain the feature map of each branch network;Fusion is the feature map of each branch network, obtains the final semantic segmentation feature map.The application extracts the semantic and spatial information of image from different resolution respectively, solves the problem of insufficient utilization of semantic and spatial information.The application also adds semantic enhancement module and feature fusion module, improve the effect of semantic information extraction while also solve the problem of spatial information being covered under multi-branch.
