Description

CROSS-REFERENCE TO RELATED APPLICATIONS The present application is based on, and claims priority from JP Application Serial Number 2024-192736, filed November 1, 2024, the disclosure of which is hereby incorporated by reference herein in its entirety. BACKGROUND OF THE INVENTION 1. Technical Field The present disclosure relates to a data mapping method, a data mapping system, and a robot monitoring system. 2. Related Art In recent years, management systems for factories using IT technology are developed. More specifically, the management system collects information on equipment used in factories and performs visualization of an operating status of the equipment based on the collected information. The management system is also called a cyber physical system (CPS) or an Internet of Things (IoT) system. Hereinafter, the equipment used in factories is also referred to as a "device". The information collected by the management system is stored in, for example, a database constructed in a server on a network. In order to store the collected information in the database, a user determines a storage location of the collected information on the database in advance. Further, the user determines the storage location according to the type and use of the collected information. JP-A-2023-43079 describes a technology for determining a candidate storage location among a plurality of storage locations referred to as a class and a property in a standard data model. In the technology of JP-A-2023-43079, when there are a plurality of candidate storage locations, the storage location selected by the user among the plurality of candidate storage locations is determined as the storage location of the collected information. In the technique of JP-A-2023-43079, as a method for detecting candidate storage locations, for example, it is detected whether or not a device name included in a schema name of data completely matches or partially matches an item name defined in the storage location. In the following, determining the storage location of the collected information is referred to as "mapping". However, when the mapping work is performed by the user, the workload of the user increases depending on the type and amount of data to be collected. Further, the mapping work may require expert knowledge about the device. Therefore, even when the number of types of devices increases, the workload of the user involved in the mapping work increases. Therefore, a technique for reducing the burden of the mapping work is demanded.
