Fig. 4 describes an embodiment of method 400, wherein based on the route of the next adaptive collecting device of state 500 pairs of technicians' displays of the machine along route.The method starts from frame 402, and wherein technician selects the expectation route being used for Data Collection and analysis, and such as, such route inventory by using man-machine interface 504 to show from the display 506 of collecting device 500 is selected.As described in frame 404, be accredited as the machine inventory belonging to selected route before relevant to selected route is, such as, identified by engineering.
In certain embodiments, collecting device 500 accesses multiple data source, such as, data record in remote computation or memory device, to determine whether data collect each machine on this route.In certain embodiments, the state of machine is determined then and there, and collecting device 500 whether decide to collect data from this machine based on the state of machine at least in part suitable.In certain embodiments, collecting device 500 only observes the timetable of the Data Collection of the machine recorded, and itself and record sheet when finally summarizing data is compared, and determines whether this machine to be incorporated to this route.
In certain embodiments, technician be in machine other time make whether from the decision of the machine aggregated data of specifying.In further embodiments, when the beginning of route development, machine is incorporated to route, or gets rid of from route, then technician starts this route of walking.In certain embodiments, adopt the combination of these two kinds of methods, and route selection start be incorporated to or get rid of some machines, and such as when technician be about to from machine collect data time, the state based on machine is incorporated to or gets rid of other machines.
Under any circumstance, if in block 406, machine should be used for Data Collection, then as described in frame 408, collect data, and its step is corresponding with the method 100 of Fig. 1.As described in frame 410, determine whether to collect more multimachine device on route.If collected, then the method is back to frame 404, and if do not collect, then, as described in frame 412, completes route and Data Collection.
Use example
Excessive data based on collected data is collected
In this case, the slip-stick artist defining Data Collection route wish by the amount of collected data and relevant data collection time minimum relative to the machine suitably run.But if normal data and machine state display device may have problems and alert trigger (defining alarm condition during method to set up), then slip-stick artist wants the technician collecting data to collect extra data before leaving this place.In this case, during method to set up, slip-stick artist predefines for when to the extra data collection parameters group of data of will collect when normal data generation alarm.Data collection facility 500 when be in place without the need to technician or definition route slip-stick artist intervene obtain extra data.
Embodiment
If read on induction motor, and comprise the analytical parameters alert trigger of AC current peak (that is, 120Hz), then launch higher resolution spectrum to distinguish 2 × RPM and 2 × line frequency.
If the high frequency alarm of any type of measurement triggering, then extend and carry out the frequency measured, lay equal stress on and collect data, to make analyst, there is definite signal frequency feature in high-frequency domain.
If initial reading displayed, the vibrational energy of signal portion is hyposynchronous, then carry out SST and measure to obtain being worth more accurately for the lower part of composing.
Benefit
Save time: because extra data are collected when technician has been in machine place, so without the need to returning machine afterwards to collect excessive data.
Preserve measuring position: some readings can only be carried out in specific position.If first measures and detect at A place, position, and technician returned to collect extra diagnostic data at position B (its can very close position A) place afterwards, then in the vibration signal of new reading, this defect mode may be sightless.
Catch temporal event: some machine defects are induced by the particular configuration of manufacture method.The sign that the initial reading of collecting during method configuration A can show clearly mechanical defect---such as resonating---.If technician returned to collect extra diagnostic data in the moment afterwards, then this machine can run under different conditions, and wherein this defect is no longer visible.
Intermittent duty: many machines are only by the requirement intermittent duty of production method.The machine being in operation carries out initial read get personnel can be impelled to return on the date afterwards to collect extra diagnostic data, but machine does not rerun; Therefore, have no chance to collect any extra data.
Extra measurement requirement
In this case, if some situation is genuine, then the slip-stick artist defining route wishes to collect extraneous information on machine, and this requires the extra behavior being in the technician in machine place.In this case, once have rated the current state of machine or collection and after have rated raw data, namely determine, technician should change common method and collect excessive data.This excessive data should be in different measuring position, or it can need the participation of technician, such as impact test.Once after collecting device 500 determines to need to carry out extra Data Collection, namely impel technician to take specific behavior to receive data.
Embodiment
If initial reading displayed, the vibrational energy of signal portion is asynchronous, then impel technician to connect velocity gauge, carries out Velocity Detection algorithm, then reappraise with the velocity survey improved, or use new velocity survey heavily to collect reading as the basis of reading.
If the data display of collecting may exist resonance, then impel technician to carry out the impact test of some number of times to machine, then vibrate to deduct travelling speed from reading by carriage return.
Benefit
