ABNORMALITY DETECTION SYSTEM, DISPLAY DEVICE, ABNORMALITY DETECTION METHOD, AND RECORDING MEDIUM

摘要

An abnormality detection system includes a processor configured to execute a process. The process includes: storing log data in a storage in which at least a production device number is associated with the event date and time; referring to the log data stored in the storage and calculating a temporal relationship between a first device and a second device that subsequently performs a process after the first device from among a plurality of production devices; detecting elapse of a reference time that is obtained from both the latest log data from among the pieces of log data related to the first device stored in the storage and the temporal relationship calculated at the calculating and that new log data related to the second device is not newly stored in the storage; and displaying an alarm when detection is obtained at the detecting.

1. An abnormality detection system comprising:
a processor configured to execute a process including: storing log data in a storage, which is related to each of a plurality of production devices that are included in a production line and that produce a product by sequentially performing processes, and in which, for a process related to production of the product performed by each of the production devices, at least a production device number is associated with the event date and time; referring to the log data stored in the storage and calculating a temporal relationship, of the production of the same product, between a first device and a second device that subsequently performs a process after the first device from among the plurality of production devices; detecting elapse of a reference time that is obtained from both the latest log data from among the pieces of log data related to the first device stored in the storage and the temporal relationship calculated at the calculating and that new log data related to the second device is not newly stored in the storage; and displaying an alarm when detection is obtained at the detecting.
