[0065] Functional Configuration of Anomaly Detection Device
[0066] figure 1 is a functional block diagram illustrating the configuration of the abnormality detection device according to the first embodiment. also, figure 2 is a schematic diagram illustrating an example of the system configuration of the entire anomaly detection system. The abnormality detection device 100 includes a communication unit 101 , an output unit 102 , a control unit 110 and a storage unit 120 .
[0067] The communication unit 101 is realized by, for example, a network interface card (NIC) or the like. The communication unit 101 is a communication interface connected to a recording device 200 to be described later via a network in a wired or wireless manner, and manages information communication with the recording device 200 .
[0068] The output unit 102 is a processing unit that outputs the graph created by the control unit 110 to various output media such as a monitor, a printer, and the lik...

[0273] In the second embodiment, similar to the first embodiment, for each product, the start time and end time of each step are also indicated based on the record data 121 . Based on the specified start time and end time, the processing period is set and the bars formed by connecting the processing periods are displayed in the graph. On the contrary, the second embodiment is different from the first embodiment in that when the processing period or the waiting period of the product is set on the time axis associated with each step, a mark indicating the processing period or the waiting period of the product is set . Since the functional configuration of the abnormality detection device according to the second embodiment is the same as that of the first embodiment, description thereof will be omitted.
[0274] Display example of graph according to second embodiment
[0275] A display example of a graph according to the second embodiment will be described. Figure 48 is a sch...

[0290] In the first example, given figure 2A description of a case where the production devices 300 a to 300 d output both the start time and the end time to the record data 121 shown in ; however, the embodiment is not limited thereto. The production devices 300 a to 300 d may also output one of the start time and the end time to the record data 121 . A description will be given of an example of one of the output start time and end time of the production apparatuses 300 a to 300 d as the third embodiment.
[0291] In this case, the log data 121 stores therein only the start time or end time of each step. The calculation unit 111 calculates the time difference between the time when the first device starts production and the time when the second device starts production or the time difference between the time when the first device ends production and the time when the second device ends production based on the record data 121 . If the start time is stored, the sum of the ave...
