A kind of data for the transmission printing machine are proposed to the remote maintenance computer method by patented claim EP1207434A2.Before the service data of machine transfers to the remote maintenance computing machine, carry out the assessment of data.At this, service data and one or more threshold value are compared, and only when surpassing, being lower than or reaching one or more threshold value, just service data is automatically transferred to the remote maintenance computing machine.This has the following advantages: be not constantly but only to give the remote maintenance computing machine with the data transmission of the computing machine of printing machine when surpassing threshold value and when expecting the inefficacy of certain probability or fault.By described methods the data transmission between the computing machine of remote maintenance computing machine and printing machine is reduced to minimum.
By patent US7,454,263B2 proposes a kind of operation agent of supporting the unfamiliar operator of printing machine.Patent US7,860,587B2 support the operation of printing machine equally.
Summary of the invention
Task of the present invention is further to improve generation and the analyzing and processing of the service data in the remote maintenance system of machine and can realize safeguarding accurately predicting with maintenance requirements.
According to the present invention, described task solves by claim 1.Favourable configuration of the present invention is drawn by dependent claims and accompanying drawing.The method according to this invention is suitable for trying to achieve and has computing machine and the machinery that preferably is connected with remote maintenance computing machine that fabricator or ISP locate by the internet and maintenance and the maintenance requirements of equipment.Especially, the method according to this invention can be used for safeguarding complicated machine---as printing machine, because high acquisition cost must be guaranteed its availability incessantly.In the method according to the invention, leave in the file of controlling on the computing machine according to the rule of determining in the service data of run duration detection machine and with described service data.Determine how and when what kind of service data storage rule hereof to be depended on according to the present invention the state of machine.This causes: needn't be continuously with the service data storage hereof, and ability storage running data when rule predetermining only.Yet when the state variation of machine (may by wear phenomenon or the machine operation by changing), described rule match be in the machine state of described change, and according to the rale store service data that changes.Therefore guarantee unnecessary a lot of data to be stored in the machine computing machine, but for example under the higher wear and tear in machines since the operation that changes when expecting inefficacy and correspondingly needing data more storage running data correspondingly when analyzing with trouble-saving.
In first configuration of the present invention, propose, just service data is stored hereof in the time of only beyond service data to be detected is located at the predetermined margin of to lerance of depositing in the control computing machine.In described situation, service data is compared with the predetermined margin of to lerance of depositing in the control computing machine enduringly, but as long as data are positioned at predetermined margin of to lerance then to abandon and not store described service data again.When surpassing predetermined margin of to lerance or this and repeatedly occur just the storage running data and subsequently correspondingly lost efficacy or the probability of fault aspect the described service data of analyzing and processing.The amount of the service data of storing can be reduced to minimum by described methods in the file of control in the computing machine.Especially at the machine of complexity---as have a plurality of CD-ROM drive motor and regulate in the printing machine of drive unit (its all must be managed and have certain property easy to wear), only store for the important relevant service data of may losing efficacy of machine and subsequently it is transferred to the remote maintenance computing machine.
Advantageously propose, the service data storage moment or time interval hereof depended on machine state.This for example is another criterion of the storing process that influences service data except surpassing predetermined margin of to lerance.So for example can a predetermined standard time interval, thus service data when surpassing predetermined margin of to lerance, in very first time interval, periodically monitored.Surpass margin of to lerance if another takes place in bigger second a predetermined time interval, then implement the storage of service data more continually and correspondingly dwindle very first time interval, thereby with short cycle storage running data.
Advantageously propose, described margin of to lerance is lower than a maximum figure, the inefficacy of expection machine when described maximum figure.Guarantee to surpass margin of to lerance and also do not estimate the inefficacy of machine immediately under the situation of storage running data subsequently but at least under any circumstance all guarantee the continuation operation of short time in property at least one times by described methods.
Particularly advantageously propose, service data comprises the electric current change procedure the when CD-ROM drive motor in the machine is moved.Such as already mentioned, printing machine has a plurality of electric drive motors.The state that can derive CD-ROM drive motor or the regulating device by the CD-ROM drive motor operation by the electric current change procedure of control during CD-ROM drive motor how.When torque was higher owing to the wearing and tearing at motor place or regulating device place when in the control CD-ROM drive motor, motor current raise or shows and is subject to invasion property, as steeper rising and decline.Especially because higher motor current can surpass the margin of to lerance of determining, thus motor current is stored as the service data in the file and described data can be transferred to the remote maintenance computing machine subsequently.
Propose in addition, the service data of an assembly in the machine is compared with the service data of the identical or similar assembly of machine and only under the situation of deviation service data stored hereof.The described lateral comparison that relatively is used as a kind of reasonableness test and guarantees before the storage running data, at first to implement the identical or similar assembly in the machine.Can identify the unusual of an assembly with respect to the identical or similar assembly of machine by described methods, thereby only must store the service data that relates to unusual assembly.
In another configuration of the present invention, also propose, only in the time interval that assembly also activates, detect or store the service data of the assembly of machine.This also is used for stoping service data to record hereof meaninglessly.Like this, when under the situation of at all not operating motor, recording the motor current of CD-ROM drive motor, can not get any identification benefit, because motor current equals zero.Therefore only when CD-ROM drive motor also be activate and when implementing adjustment process with the motor current detection and be stored as service data and be only significant.Especially in the printing machine with a lot of adjusting drive units, can reduce recorded data amount in the file.
Advantageously propose, the control computing machine of machine by network connection with on the position away from computing machine is connected and control computing machine consideration on the position away from the situation of data of computing machine under mate for detection of with storage file in the rule of service data.The control computing machine that in described situation, can realize machine not only be used for the rule of storage data based on the machine state coupling and also consider together on the position away from the regulation of maintenance calculations machine.By described methods can realize by the internet with the experience of other machines be transferred on the position away from computing machine and be transferred to from described computing machine on the control computing machine of machine.The coupling of the rule on the control computing machine can benefit from the experience of other machines.Alternatively also can realize, the control computing machine by network connection and another machine on the position away from the control computing machine directly is connected and like this consideration on the position away from the control computing machine in mate under the situation of the data of storing for detection of with storage file in the rule of service data.In described situation, not necessarily need be on the position away from computing machine and control computing machine can be directly from the coupling of the rule of other control computing machines of similar or identical machine, benefit and its knowledge of consideration in its own matching process.
Description of drawings
Below describe and set forth the present invention with reference to the accompanying drawings in detail: accompanying drawing illustrates:
Fig. 1: have three by the remote maintenance computing machine of the printing machine that has a control computing machine respectively of internet connection,
Fig. 2 a: according to the service data record of prior art,
Fig. 2 b: according to the service data record according to dynamic programming of the present invention.
Embodiment
In Fig. 1, schematically shown the general view of the assembly that participates in of remote maintenance system.Supervisory computer 2 is positioned at fabricator 1 place, and described supervisory computer connects 9 from printing machine to be safeguarded 7 acquisition maintenance and maintenance requirements and service datas by the internet.The attendant 4 that is seated in supervisory computer 2 fronts, it can show the maintenance needs of printing machines 7 and service data and can so determine corresponding on-the-spot service to drop into or other remedial measuress at screen 3 by means of the input by keyboard 12.Printing machine 7 to be safeguarded has a control computing machine 8 respectively, the printing machine 7 under the described control computer control.By control computing machine 8, press operator 5 can be controlled the repertoire of printing machine 7.In Fig. 1, printing machine 7 exemplarily has a printing mechanism respectively, and described printing mechanism has at least one electricity and regulates drive unit, for example deposits the adjusting drive unit.These are deposited the adjusting drive unit and are assigned a current sensor 11 respectively, and described current sensor detects and deposits the electric current change procedure of CD-ROM drive motor and it is transferred to printing machine computing machine 8.
According to the prior art among Fig. 2 a, the service data in the machine computing machine 8 is according to giving the rale store on ground regularly in advance in a definite journal file.Analyze based on described journal file implementation data subsequently and the identification of preventative sign, its result can connect 9 by the internet among Fig. 1 and be transferred to fabricator 1.
Propose now according to Fig. 2 b, journal file is dynamic, and the rule and the content that namely leave in the journal file are the states that changes and especially depend on machine.Can make the amount of data and type matching in machine state by described methods, thus more easy to wear in service correspondingly more and record service data more continually at machine 7.Data volume can be restricted to minimum and still guarantee before printing machine 7 loses efficacy, to identify demand for services in time and described demand for services is reported to fabricator 1 in that the variation with higher wearing and tearing is in service by described methods.Depositing the data technique of the printing machine 7 of dynamic system form in journal file describes.By control computing machine 8 automatically assess and aspect the prompting of failure symptom the analysis journal file data.By the suitable association of the failure symptom under the situation of the boundary condition of considering to be determined by operation, identified, can identify the fault at printing machine 7 places reliably.
Also can improve the remote maintenance system that is used for remote diagnosis that has existed by using according to dynamic log file of the present invention.At this, according to its ins and outs characteristic printing machine 7 is considered as dynamic system, it stands continuous variation.At this, in case observed value shows that clear and definite trend or described value with respect to suitable component variations, then especially detect the variation of physical quantity as dynamic change.For described purpose, in two printing machines 10, detect the motor current of carrying out the CD-ROM drive motor of the motion in the printing mechanism 10 by the spindle machine device by means of current sensor 11 respectively.At this, the time current change procedure changes in failure situations, because for example the pitch of main shaft is in interval internal contamination observing time and occur the blunt of mechanical hook-up thus
Therefore, can realize the identification early of imminent fault by the suitable observation of described dynamic process, namely motor is owing to bluntly at a time can not rotate fully again.Therefore at this, the interval was conclusive and detected and the memory technology data must correspondingly be mated when carrying out the failure symptom analysis observing time.If observing time, interval selection ground was improper, only then can not tries to achieve around the fluctuation of intermediate value or have ascendant trend or downtrending.
In addition, by the directly relatively dynamic change of recognition function assembly between the described assembly.In this service data of detecting of analyzing and processing each other.So for example the current drain of the CD-ROM drive motor in the printing mechanism 10 is compared with similar or identical CD-ROM drive motor in another printing mechanism 10.By can the be compared to each other electric current change procedure of all the suitable CD-ROM drive motor in the printing machine 7 of described methods.Additionally, can realize also and the comparison of the CD-ROM drive motor of other machines 7 that its mode is to connect 9 by the internet its data are provided.But it is significant that the detection of service data only is only when the adjusting drive unit also moves.For described reason, observing time, detection interval and service data was limited to following time interval: in described time interval CD-ROM drive motor be activate and the execution adjustment movement.
At this, observing time, the interval itself also can be used for the failure symptom analysis fatefully, for example measured the time in the suitable governor motor path of process definition in the time section of determining in other printing mechanisms 10 like this as measuring amount.When for example other physical measurement amounts---when not existing as voltage, electric current, torque etc. immeasurability or corresponding sensing mechanism, also can use described mode of operation.Then carry out fault analysis according to the suitable characteristic of CD-ROM drive motor.In regulating drive unit, only the position feedback of regulating drive unit in the time interval of expectation---for example the restriction of zero position or limit switch is just enough.By described methods only can realize when service data when also being meaningful, when related assembly be actually activation the time just detect service data.The storage that also can improve data under the situation that the load of machine improves is in order to can require maintenance measure to fabricator 1 in time before machine failure.Therefore, dynamic log file according to the present invention can realize machine 7 flexibly, reliably and save the operational monitoring of data and stop reliably and lost efficacy because can require maintenance needs in time.
