Definitions

  • the invention relates to a method for fault isolation and diagnosis at a fluidic system, wherein the fluidic volume flow of the entire system or at least a portion thereof and the fluid pressure during each operating cycle is detected and compared with stored references, and wherein at the time of a deviation or a change the deviation from the reference is determined in which component or components of the system, the fluid consumption influencing process has taken place to then recognize them as faulty.
  • the air consumption curve is evaluated for error localization.
  • the time of the deviation on the faulty subsystem for example, valve actuator unit.
  • Such errors which can occur in fluidic systems, have their causes, for example, in the wear of the components, improper mounting, loose fittings, porous hoses, process disturbances and the like., Which manifest themselves in the movements of the fluidic drives, and other leaks of various kinds Diagnostic errors due to changes in certain boundary conditions, such as pressure and temperature, to avoid, this document mentions the possible correction of air consumption with pressure and temperature.
  • the method for this is not described, and temporal or batch-dependent fluctuations can not be considered.
  • An object of the present invention is to improve the method of the aforementioned type so that changes in the boundary conditions and in particular different operating conditions are taken into account so that they do not lead to misdiagnosis.
  • the advantage of the method according to the invention is, in particular, that the diagnosis by means of the conductivity value easily compensates for natural fluctuations in a fluidic system, caused by unavoidable pressure and / or temperature fluctuations.
  • different operating states can also be taken into account by selecting corresponding stored reference value reference curves.
  • the comparison of the conductance with a reference and possible deviations in terms of time as well as amount allow very exact statements on the nature of the fault and the location of the fault.
  • the different operating states for which master value reference curves are stored for selection preferably relate to the warm-up, the operation after a longer standstill, the restart during retrofitting and the operation after predefinable time intervals.
  • the Leitwertieren be compensated for even better adaptation to the behavior of the overall system temperature dependent, in particular by the factor 1 / T .
  • T is the operating temperature.
  • the Leitwertieren can also be adapted fluid dependent, in particular by the factor K F .
  • K F is a fluid-dependent characteristic value.
  • Even more accurate diagnostic data and diagnostic statements are obtained by adapting the Leitwertyn by the moisture content and / or the particle content of the respective fluid, in particular by the factor 1 / K H . where K H is a dependent moisture and / or particle content characteristic value.
  • the selected reference In order to be able to take account of different operating states, that is to say to ensure that the comparison between the reference value and the current master value yields a correct statement, the selected reference must correspond to the corresponding operating state. This means that from the stored selection matrix the reference value curve corresponding to the respective operating state has to be selected.
  • this is before the diagnosis of leakage, the duration of an operating cycle by comparing the current Leitwertmesskurve with this operating cycle assigned Leitwertreferenzkurve checked, with only a predetermined deviation, the switchover to at least one more Leitwertreferenzkurve.
  • a runtime deviation is detected, the presence of a proportional time shift between the actual master value curve and the master value reference curve is additionally checked, and only in the case of a determined proportional time shift does the switch to at least one further reference value reference curve take place. If, after checking all master value reference curves, it is determined that all of them exceed the specified deviation, the entire system is far outside the operating point and a corresponding message is generated. The diagnosis of leakage is then not carried out because it makes no sense.
  • FIG. 1 a pneumatic system is shown schematically, which could in principle also be another fluidic system, such as a hydraulic system, act.
  • the pneumatic system consists of five subsystems 10 to 14, which may each be actuators, such as valves, cylinders, linear drives and the like, act, as well as Combinations thereof. These subsystems 10 to 14 are fed by a pressure source 15, wherein in a common supply line 16, a flow meter 17 for measuring the flow or the volume flow is arranged.
  • An electronic control device 18 is used to specify the process flow of the system and is electrically connected to the subsystems 10 to 14 via corresponding control lines.
  • the subsystems 10 to 14 receive control signals from the electronic control device 18 and send sensor signals back to them.
  • sensor signals are, for example, position signals, limit switch signals, pressure signals, temperature signals and the like.
  • the flow meter 17 is connected to an electronic diagnostic device 19, which in addition to the signals of a temperature sensor 20 and a pressure sensor 21 for measuring the temperature (T) and the pressure (P) in the supply line 16, ie the temperature and the pressure of the fluid supplied are. Furthermore, a fluid sensor 23 for detecting the type of fluid used and a moisture and / or particle sensor 24 for detecting the moisture content and the particle content of the fluid are connected to the diagnostic device 19. This has additional access to the sequence program of the electronic control device 18. The diagnostic results are supplied to a display 22, these diagnostic results of course also stored, printed, visually and / or acoustically displayed or a central office via lines or wirelessly can be transmitted.
  • the diagnostic device 19 can also be integrated in the electronic control device 18, which may contain, for example, a microcontroller for carrying out the sequence program and optionally for diagnosis.
  • each group has its own flow meter 17 to independently diagnose the subregions of the system associated with the groups, as described in the above-mentioned prior art.
  • the procedure for fault isolation and diagnosis will now be described below with reference to the described pneumatic system and in the FIGS. 2 to 4 illustrated Leitwertdiagramme explained.
  • the influences of the temperature T and / or the characteristic values K F or K H can also not be taken into account, so that in the simplest case the conductance depends only on the volume flow and the admission pressure.
  • the conductivity is additionally dependent on time and / or batch, that is, depending on the operating condition, other conductance curves arise.
  • Such operating states are, for example, the warm-up, the operation after a long standstill, the reclosure when retrofitting or the operation after predetermined time intervals, so for example after a one-hour or ten-hour or several hours of operation.
  • the diagnostic control value or the diagnostic control values are characteristic variables of a fluidic system or a fluidic system that consists of a variety of subsystems.
  • the conductance characterizes the behavior of the entire system or a subsystem over a defined repeating cycle. It compensates for normal fluctuations and fluctuations in the operating variables pressure, temperature, humidity, particle content, depending on how complex it is formed.
  • the evaluation of this conductance by reference comparison, ie comparison with stored master value reference curves, thus showing the errors and the causes of errors in fluidic systems.
  • a parameter-dependent master value reference curve adapted to the respective operating state must be selected. This takes place initially as a function of the applied sensor signals. Then, the runtime of the system is first checked as a function of the respective operating state and checked for correlation with the initially selected master reference curve. If the selected master value reference curve correlates with the current measured curve, the diagnosis is released. Deviations then actually indicate a leak in the detected period and can be assigned to these error-causing actuators in accordance with the sequence program.
  • the diagnosis is released, that is, the Deviation does not stem from a time shift, but from a malfunction of the plant ago, in particular from a leak.
  • the measured conductance curve K Da deviates continuously more and more from the conductance reference curve K Dref .
  • the difference ⁇ K D increases more and more with time t and is a function of time.
  • a deviation ⁇ K D occurs, which remains constant from this point in time until the end t e of the cycle.
  • a subsystem for example a valve actuator unit that was active at time t1
  • the timing of the deviation may be compared with the process image or control program in the controller 18 to locate the error-causing subsystem. If several subsystems were active at time t1, which could be the case for larger systems, the error must be limited during the following activities of these subsystems in which they are no longer active together.
  • the cycle duration has changed by the value .DELTA.t, the change having occurred at the time t2.
  • the value of the conductance remains constant from this time t2, there is only a time shift. This allows the conclusion that the travel time of the active at this time t2 actuator has changed, for example, by clamping, increased wear, switching errors on the valve or the like. It is thus also possible to detect time errors in the pneumatic system based on the conductance.
  • FIGS. 2 to 4 reported occurrences during a cycle cumulative and / or occur multiple times. By corresponding curve, several different errors occurring during a cycle can then be detected. For safety, of course, the diagnostic cycles will be repeated upon the occurrence of a fault to determine if it is a one-time fault or a faulty measurement or fault.
