The invention discloses an intelligent identification power distribution network fault prediction method fusing relay protection data, and belongs to the technical field of a power transmission and distribution network of a power system, and the method comprises the following steps: S1, collecting and fusing multi-source heterogeneous data; s2, constructing feature engineering and a dynamic knowledge graph; s3, multi-modal deep learning model training is carried out; s4, carrying out incremental learning and adaptation on a model based on transfer learning; and S5, fault early warning and decision support are carried out. The relay protection action event sequence and the fault recording data are fused with traditional SCADA measurement data, standing book information and historical records, the limitation that only SCADA or a single data source is used in a traditional method is broken through, the protection action event reflects the most direct response of the system to abnormity, and fault symptoms can be captured earlier and more accurately.

To provide a vehicle information history management method configured to easily improve the accuracy of obtaining information on a failure, or the like, of a vehicle, and a vehicle information history management system.SOLUTION: A vehicle information history management system 1 includes: a receiving processing unit 211 which receives a frame number N of an automobile C to be subjected to a service, and vehicle information D which is information on the automobile C or information on the service in association with each other, from terminal devices T disposed in stores S which provide the automobile-related service, via a network 3; a storage unit 22; a storage processing unit 212 which stores the received frame number N and the vehicle information D in association with each other in a cumulative manner on the storge unit 22; and a browsing processing unit 213 which transmits, on receipt of a request for the vehicle information D corresponding to the frame number N from one of the terminals T over the network 3, the vehicle information D cumulatively stored in association with the frame number N, to the one terminal T over the network 3.SELECTED DRAWING: Figure 1

The present disclosure provides computer program products and systems. The computer program product causes a processing unit of a computer to execute a process for displaying period information indicating a state of an object in an object period for each object period of a predetermined length on the basis of history information relating to a history of the state of the object, the history information includes information pertaining to the state of the subject in each of a plurality of recording periods, and information pertaining to at least one of the plurality of recording periods includes information pertaining to a history in which the subject is subjected to a plurality of external stimuli. The computer program product causes a processing unit of a computer to execute a process for performing a plurality of external stimuli on a subject in a recording period corresponding to a certain subject period among a plurality of recording periods, in accordance with a given priority sequence related to the external stimuli, and when the subject is subjected to the plurality of external stimuli in the recording period corresponding to the certain subject period. The execution unit causes the display unit to display period information indicating that the subject is subjected to a certain external stimulus during a certain subject period.
