  • Patent number: 12222907
    Abstract: Embodiments of the present disclosure provide a method, apparatus, device and storage medium for data processing. If a kernel module sends a data calling request to a userspace process, first modification time information and second modification time information of data corresponding to the data calling request are obtained by the userspace process. The first and second modification time information are used to indicate modification time information of the data in the kernel module and in a file service end, respectively. The first and second modification time information are compared by the userspace process. If the first and second modification time information are inconsistent, a verification invalidation result is returned to the kernel module. The data in the kernel module is invalidated by the kernel module according to the verification invalidation result. The data in the file service is synchronized by the userspace process to the kernel module.

  • Publication number: 20250045249
    Abstract: Embodiments of the present disclosure provide a method, an apparatus, a device and a storage medium for data request processing. The method is applied at a filesystem in userspace which includes a kernel module and a userspace process. The method includes: obtaining a data request list in the kernel module, where the data request list includes a plurality of data requests to be processed and virtual address information corresponding to respective data requests of the plurality of data requests; querying, for each of the data requests, physical address information corresponding to the virtual address information, according to the virtual address information corresponding to the data request; querying target cached data corresponding to the data request, from a plurality of cached data stored in the kernel module; accessing the target cached data, and processing the data request.

  • Publication number: 20230115586
    Abstract: A construction method of digital twin for structure performance of an intelligent excavator. Through the finite element analysis on key parts in the process of the intelligent excavator, the relevant structural mechanics performance is obtained; The important operating states of the key parts of the intelligent excavator in the excavation process are collected, and the key operating data are obtained through data processing and calculation; sensor data and an artificial intelligence algorithm are fused, and the structure performance of the parts of the intelligent excavator under multiple unknown working conditions is predicated by using a prediction model; and finally, the performance data information is modeled and rendered by computer graphics technology, to obtain a digital twin of the structure performance display of the intelligent excavator is obtained, thereby realizing digital twin mapping of the performance information on key parts of the intelligent excavator in the excavation process.
