Embodiment Construction
[0055] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0056] Before the architectural big data caching method provided in this embodiment, the mobile edge caching architecture of architectural big data, that is, the MEC (Mobile Edge Computing, mobile edge computing) architecture is introduced. This MEC architecture ensures the QoS of the application during the build life cycle.
[0057] The MEC arch...

An embodiment of the present invention provides a method and device for caching large architectural data. The method includes: obtaining the number of times an application program accesses an MEC server in the MEC server layer within a historical period of time, and obtaining the number of times each MEC server is accessed. The state of the MEC server layer; the state of the MEC server layer is input into the pre-trained deep reinforcement learning model, and the MEC server in the MEC server layer to be cached in the content item of the building data obtained by the application program access is output; The content item is cached again in the MEC server where the content item is to be cached. The embodiment of the present invention optimizes the caching performance of building big data, and provides reliable service quality for applications in the life cycle of the building.
Description
technical field [0001] The invention belongs to the technical field of building information, and in particular relates to a method and device for caching large building data. Background technique [0002] Buildings are major components of cities and major consumers of resources and energy. During its life cycle, buildings continue to have a significant impact on the natural environment. At the same time, environmental impacts and stricter environmental regulations require the construction industry to manage resources more efficiently. The management and decision-making driven by construction big data is the key to the transformation and upgrading of the construction industry. [0003] The life cycle of a building can last for decades or even centuries, including building design, building construction, and building operation. In these processes, each construction involves many participants, such as construction parties, general contractors, subcontractors, material and equ...
