I have been looking into many work-orders looking for failures or anomalies, but at this point I’m not sure to take the most of the shared information, as example I’ll take the two following events: The work order 6516382362467974 has the following details available: Description: Exterior leakage - liquid for the main process Shutdown: Revision (full shutdown) Planned Start: 2014-09-11 I also plotted some of the signals from near the planned start, as shown in the below image: I have a few questions about the first work order: It seems that the compressor turned off about two weeks before the planned start time (As the green dotted line shows) is it safe to assume that is discrepancy is because the two-week delay in sharing the data? Is there a set of signals that I can look into for this work-order, I’m assuming that since there is a leakage, the time series related to lube oil could be affected, or maybe the pressure of the compressor. The second work order is 54865032
There are some signals that in the names or the description have the words: alarm, warning, or fault. E.G. There is this alarm signal, (in red ) that I’m comparing with one of the vibration signals. And the alarm seems to be on when the vibrations are close to 0 and the Compressor is off. I’m plotting the label as a combination of the name and the description, but the externalId of the alarm is: pi:160268In most cases that alarm is on when the compressor is off, except in this case, Where I do not see any problem with the vibration signal: There are these other two alarms, from the plots: one is on when the compressor is off and the other one when it is starting up. But I do not see any strange behavior in the signal when they occur. Besides the alarms, I’ve also looked into some of the fault signals but those seem to be on for very long times: Is there another way to use the alarm and fault signals to label anomalies or failures? I don’t know if using the vibration signals is the bes
I'm working on identifying the falling and rising edges of the VAL_23-KA-9101-M01:HSI.StatusMotorOn signal. For that and shifting the TS and rest the values, if I get -1 is a falling edge and for 1 it is a rising edge. For the first row it works fine: But I’m also getting a lot of values different than 1 or -1. Especially for more recent years. I guess that the problem is at the aggregating step, since I downloaded the data at a 1m frequency I get not int values for some records. Now, I was trying to download this TS at a 1s frequency, but I get a different number of records depending on the year. E.G. for 2014 I get 34 records for a 10 days time windows with a granularity 1m. If I do the same but for 2020 I get 1411, much more than for 2014, but still a tenth of the expected count. If I change the granularity to 1s, I still get the same number of records, but with more precision in the time stamp: Considering this, is there a recommended granularity to download the data and min
I'm working with the time series data for anomaly detections models and I would like to know the units of the sensor data. I found a master thesis based on the Open Industrial Data and for the variables selected for it; the author specifies the units: But from the data I downloaded with the SDK the tag VAL_23_KA_9101_M01_62C:Z.X.Value does not have unit: I looked into the meta data field an the engunits key is empty:{'P&ID No': None, 'PLC': None, 'PLC tagname': None, 'Sensor type': None, 'Tag group': None, 'Tag type': None, '_replicatedInternalId': '4326942079596138', '_replicatedSource': 'akerbp', '_replicatedTime': '1593024714000', 'archiving': '1', 'compdev': '0', 'compdevpercent': '0', 'compmax': '28800', 'compmin': '0', 'compressing': '1', 'convers': '1', 'descriptor': 'PH 1stStg Comp Mtr Current', 'digitalset': '', 'displaydigits': '-5', 'engunits': '', 'excdev': '0', 'excdevpercent': '0', 'excmax': '600', 'excmin': '0', 'exdesc': '', 'external id': None, 'filtercode':
Hi, is is the any way to download the CAD files of the Vulkan Control Room? Or the CAD files of any of the assests? for example the heat exchanger?
