Description

Diagnostic device Cross reference to related applications The present application is based on japanese patent application No. 2023-176818, filed on 10/12 of 2023, the contents of which are incorporated herein by reference. Technical Field The present disclosure relates to diagnostic devices. Background Conventionally, as a monitoring device, a monitoring device has been proposed in which analysis of the cause of an abnormal operation is facilitated by simultaneously reproducing data at the time of abnormality detection (for example, refer to patent document 1). Specifically, an image signal captured by the monitoring camera is input to the image processing device, displayed on the multi-window display, and stored in the main storage device. The sound signal collected by the microphone is input to the sound processing device and reproduced by the speaker, and is stored in the main storage device. When an abnormality is detected in the monitored object, data before and after the abnormality detection is transferred from among the data stored in the main storage device to the auxiliary storage device. Next, the transferred data are synchronized with each other and reproduced by a display and a speaker. This makes it possible to easily analyze the cause of the abnormality. Prior art literature Patent literature Patent document 1 Japanese patent laid-open No. 6-289927 Disclosure of Invention According to the study of the inventors, in the above-described monitoring device, data is repeatedly stored in the main storage device in advance, and a large amount of data is recorded in the main storage device. Therefore, in order to record data in a large amount, a main storage device of a large storage capacity is required. Therefore, the storage capacity of the main storage device (i.e., the storage section) of the monitoring device (i.e., the diagnostic device) is increased. The purpose of the present disclosure is to provide a diagnostic device that suppresses the increase in the storage capacity of a storage unit. According to one aspect of the present disclosure, a diagnostic apparatus includes a storage unit configured to record data, at least one or more detection units configured to detect a state of a diagnostic object, a data acquisition unit configured to repeatedly acquire data indicating the state of the diagnostic object from the detection units, a level identification unit configured to repeatedly identify a level indicating an abnormality degree of the diagnostic object based on the data acquired by the data acquisition unit, a storage control unit configured to repeatedly record the data acquired by the data acquisition unit, together with the level and the acquisition order information, in a case where information indicating an order in which the data acquisition unit acquires the data is acquired as acquisition order information, and a determination unit configured to repeatedly record the data acquired by the data acquisition unit, together with the level and the acquisition order information, in a case where the level is higher than the lowest level, the level used when the lowest level is identified by the level identification unit is the lowest level data, and to repeatedly identify the level used when the lowest level is identified by the level identification unit is the latest data, and to store, in place of the data in a case where the level is equal to the highest level when the highest level is identified by the latest data identification unit is the latest level, and a determination unit configured to store, instead of the data in a case where the highest level is equal to the highest level when the highest level is found. Therefore, since the increase in the storage capacity for storing the latest data can be suppressed, a diagnostic device that suppresses the increase in the storage capacity of the storage unit can be provided.
