Abstract: A receiver mounted on a vehicle moving on a route manages an operation profile that stores data in which a section that is a part of the route and a communication quality in the section are associated, and can receive a first traffic and a second traffic having a lower priority than the first traffic. The receiver determines a section having a good communication quality to a transmission section where the second traffic can be transmitted with reference to the operation profile, and generates control information for controlling transmission of the second traffic not to hinder transmission of the first traffic when the vehicle is located in the transmission section.

Abstract: To improve learning accuracy, while avoiding transferring of a dataset from an edge terminal to a cloud server. A management device accessible to a target object to be managed has a processor executing a program, a storage device storing the program, and a communication interface communicable with the target object. The processor executes a reception process for receiving first environmental information representing a first environment of the target object, a first generation process for generating relevant information representing relevancy between the first environmental information and second environmental information representing a second environment of the target object, a second generation process for generating a first learned model for inference by the target object in the first environment based on the relevant information and a second learned model for inference by the target object in the second environment, and a transmission process for transmitting the first learned model to the target object.

Abstract: A data collection system pertaining to one embodiment of the present invention collects time-series data which is output from sensors installed on equipment which is a monitored object and carries out detecting an abnormality of the equipment. The data collection system stores plural fault models as data for comparison with time-series data and, in a learning process, determines a range to examine within time-series data by comparing the time-series data with each one of the fault models. An abnormality detection process includes extracting a partial frequency spectrum to examine from the frequency spectrum of time-series data, using information on the range to examine within the time-series data determined through the learning process, and carrying out detecting an abnormality of the equipment using the extracted frequency spectrum.
