Abstract: A device management system comprises a data collection server and edge server including an adapter that transfers a device-related data set of an industrial device. Upon receipt of the device-related data set and when the data collection server is unable to specify a row that both adapter identification information of the device-related data set and device identification information match, in a devices list table and when the data collection server is able to specify a location name of a row that only the adapter identification information matches, in the devices list table, the data collection server is configured to generate/assign a new unique device identification ID based on the specified location name, the locations list table, and the devices list table. The data collection server associates the new unique device identification ID with the received device-related data set, and then stores the device-related data set in the data accumulation section.

Abstract: This invention is intended to process data synchronization more efficiently. Disclosed is a data synchronization system comprising: an all records fetching unit that fetches all records of synchronization target data, i.e., data specified as a target of synchronization, from a first device that is a source of synchronization; one or more storage units to prestore synchronization destination data, namely, data that is now retained on a second device that is a destination of synchronization and store synchronization target data fetched by the all records fetching unit; and a difference extraction unit that identifies difference to be reflected in the data on the second device by using the synchronization destination data and the synchronization target data, makes identified difference reflected in the data on the second device, and, after the reflection, updates the synchronization destination data based on the synchronization target data.

Abstract: A data processing unit required for the data processing is started and a data processing unit not required for the data processing is stopped to change a part of the data processing settings or to add a new data processing setting without stopping the multi-stage data processing, and when the multi-stage data processing is executed, a rear-stage data processing unit reads the tag assigned in a front-stage data processing unit to discriminate the data processing unit that executes the data processing.

Abstract: Systems and methods described herein are directed to changing models and analytics algorithms on an edge node from a core server, which can be useful in situations such as optimized factories when the edge node is physically close to data sources such as within a factory plant. The core server or cloud runs analytics algorithms and models concurrently with data received from edge nodes, and replaces the edge node with more accurate analytics algorithms and models as applicable.

Abstract: The relationship between cache servers and backup cache servers is dynamically managed, and when a fault has arisen, a second cache server that is close in terms of distance to a PBR router that is forwarding traffic to a first cache server at which the fault has arisen is used as a backup cache server. Also, a module or a device having functionality as a cache manager and a cache agent is prepared, and with the trigger being the detection of a fault in the first cache server, the cache agent automatically alters the traffic forwarding destination of the PBR router, which is forwarding traffic to the first cache server at which the fault has arisen, to be the second cache server that is close in terms of distance to the PBR router.
Abstract translation: 高速缓存服务器与备份缓存服务器之间的关系是动态管理的，当发生故障时，第二个缓存服务器与距离PBR路由器的距离相近，该路由器正在将流量转发到发生故障的第一个缓存服务器 用作备份缓存服务器。 此外，准备具有作为高速缓存管理器和高速缓存代理的功能的模块或装置，并且通过触发器检测第一高速缓存服务器中的故障，高速缓存代理自动更改PBR路由器的流量转发目的地， 这是将流量转发到出现故障的第一缓存服务器，作为距离PBR路由器的距离很近的第二高速缓存服务器。

Abstract: A digital twin management system manages a virtual model that represents an actual physical system in a virtual space on a real-time basis. To generate an integrated virtual model by adding a second virtual model to a first virtual model, a processor of the digital twin system extracts multiple parts that can be used in common in the first virtual model and the second virtual model, generates multiple integrated virtual models that are candidates of an integrated virtual model by changing the extracted parts that can be used in common, calculates an evaluation of each of the generated integrated virtual models, and outputs configuration information regarding each of the integrated virtual model candidates and an evaluation of the integrated virtual model candidate in association with each other.
