According to one embodiment of present invention; Can defined file 120 be provided to database 70 now, said defined file 120 is especially realized the change of visual, analysis and measurement data structure in the opertaing device and is loaded into algorithm as the replacement algorithm implementing in the unit 80.More accurately: the measurement data file is used to describe surface characteristics (value that the type of demonstration, color are selected, will be shown predetermined), be used to describe for required form within database of analytical approach and the structure that is used to describe the measurement data file, will be transferred to remote state monitoring system from the measurement data of real-time part by it.(description of measurement data file structure can realize resolving simply and explaining the data of in measuring file, supplying.For example; Within file to circular moulding test (Kreisformtest); Except actual measurement data, such as the desired locations of motor and outer carriers and physical location or actual speed and the desired speed other parameters being provided also, such as speed that is provided at the sweep time that is used for writing down in the real-time part or circular diameter, advances or the like).Defined file 120 for example can be obtained under the situation of using measurement data file 130, and this measurement data file 130 is sent out the position (remote state monitoring system) of for this reason setting up to special through (having the head signaling information) running parameter of measuring one or more machines 35.Defined file 120 can be loaded into that algorithm is implemented in the unit 80 and produce change to the output of the data that changed perhaps to the data processing of the data that were processed in database 70 and the change of storage through the webserver 100 or networking client 110 at this.
At this, communication may be implemented as feasible OPC-UA (the OPC-UA=OPC unified shader (OPC-Unified Architecture) [=further improved OPC interface] of generally planning; OPC is initial: the OLE that is used for process control (Process Control).Between equipment and GDS (database server 85 that GDS=is general), can at first adopt the SCP interface 40 that stands severe tests towards equipment 30.Between GDS 85 and the webserver 100 or MES system, can adopt OPC-UA, for example in first step, adopt the SQL function visit that encapsulates through functional interface 50.Communicating by letter between the webserver 100 and networking client 110 for example can be carried out through agreement HTTPS.Also can adopt distributed system, the webserver that for example has a plurality of GDS (through the communication via UA) perhaps (for example has Oracle-DB's) central GDS is presented by the GDS of a plurality of less dispersions.
This can be provided with in the equipment of being integrated into 10 be used for by one of interface or by long term data storage about configuration data analytic unit aspect the analysis that will carry out (perhaps algorithm is implemented unit 80) with about to the mode of the result's of data analysis further processing and the inking device of method aspect configuration device 10.
For example defined file 120 being loaded into algorithm implements inking device in unit 80 or the database 70 and for example can realize the integrated new method/algorithm of form with #C-dll (dynamic link library (dynamic link library) that dll=for example utilizes programming language C# to produce); Wherein the interface between system and data analysis unit 80 can be defined by the XML file in more detail, so that for example can integrated apace any analytical approach (method) with simple mode.By (for example in defined file 120) XML file the graphic feature and the structure measurement data of surperficial characteristic, figure, characteristic, XML file have been described advantageously also.Can any analytical approach, for example circular moulding test be integrated in the system 10 with simple mode by this way.In this solution, preferably adopt emulation tool Matlab (for example be used for emulation and be used to create dll).
In other words, the system described in Fig. 1 works as follows:
At first: (for example every at a distance from two weeks) or the method for testing after critical event and collision, confirmed to starting system once in a while are used for the inspection machine state.In this case, in NC, SPS, RC, MC, intelligent drive device, intelligence sensor system, carry out the excitation of confirming, write down established data and be transmitted to the RCM system.There, the measurement data file of generation is read into and carries out verification with regard to the condition that (described in the defined file 120) limited.In this case, data quality also is verified and is stored among the DB with the measurement that will relate to the form of performance mumber (Kennzhal).And then, move real analysis subsequently to data.The algorithm that relates to is then confirmed to measure determined characteristic quantity for each, and these characteristic quantities are stored within the database again.Under the situation of circle, this algorithm for example is circular moulding deviation.To each method of testing, a plurality of figures and a plurality of characteristic quantity can be calculated, and then show.Interested especially secular trend for application person.If these secular trend change with unallowed mode, for example index rises, and the parts that then relate to can utilize additive method to come to be examined in more detail.
Secondly:
By GDS can be circularly or only when changing record aleatory variable (state, such as the temperature of motor current or drive unit) and with the form of curve map in more detail analysis time characteristic.
Fig. 2 shows the frame circuit diagram of the combination of discharge counter.At this; Real-time system 200 (this real-time system 200 is for example implemented in like the machine of other lathes of milling machine, drilling machine or lathe) and use data handling system 210, this data handling system 210 for example can be the PC that needn't implement real time data processing.On real-time system 200, can move the function of the work that is used to control machine, for example like NC program 215 or SPS program 220.Be used for controlling machine work function discharge counter MTX acr (being used to write down all types of incidents (this incident can be user's input or other external systems predetermined) basically) 225, for example NC server 230, piece preparation device (Satzvorbereitung) 235 or in interpolator 240 be processed.([configuration] only selected by the machine builder) result of piece preparation device 235 or interior interpolator 240 can be stored in the toroidal memory 250.Incident, special event, critical event or the accident (collision) 255 of the control device record through MTX acr 225 is stored in the log memory 260.Data are generated (application person can be configured this) through the firmware of control device on the one hand at privileged site.Yet, in addition also can according to NC program 215 and SPS program 220 generation incidents and with these event transmission in log memory.This log memory 260 can have very large Data Receiving capacity and therefore on the very long time period, store the incident or the accident (collision) 255 of corresponding appearance.Additionally, in log memory 260, can store (for example under collision situation) additional data 265 (for example desired locations in different coordinate systems and physical location) from toroidal memory 250.Log memory 260 can advantageously be disposed in the data handling system 210 (for example PC) that needn't implement real time data processing at this.In addition, in non-real-time data disposal system 210, can be provided for implementing to be used for the unit 270 visual and function that disposes, configuration data 275 makes the writing function parametrization within the control device firmware.For example whether be written in the daily record in this change of confirming the tool data through the user interface input.In addition, configuration data 275 also can show to user 280.
From the log memory 260 of non-real-time data processing unit 210, can send the data to general data server 85, this general data server 85 for example is connected to the webserver 100 and is connected to networking client 110 in addition through the interface shown in Fig. 1 90.Can or the result who is obtained be shown intuitively with graphics mode through networking client 110.
Log memory 260 can be read to make at this and can discern definite event and be sent out to the maintenance personal in response to these incidents through database server 85, with the machine of maintenance operation real-time system 200.For example, can discern the accident of the instrument of the lathe that moves real-time system 200.In this case; Corresponding incident or accident 255 are transmitted to log memory 260, and this log memory 260 can and can send to the maintenance technician for the machine of this operation real-time system 200 with this accident through general database server 85 according to the accident of the data identification machine/instrument that is transmitted.Obviously improved maintenance by this way to the machine that comprises real-time system 200.Under the situation of collision or other critical events, can implement other method of testings targetedly.By these other method of testings, then can be more accurately with regard to each parts of its status checking.
In other words, the system described in Fig. 2 works as follows:
Discharge counter MTX acr assembles all dependent events (from simple status information until collision).These information then can be used to assess the quality bills of materials of machine state or this machine subsequently in higher level's remote status system.
As machine event, input or message that for example can the user is specific at this be considered as incident.As special incident, fault or BA conversion can be within considering.Critical event for example can be the clamping of tool holding system.When instrument during Be Controlled, can be discerned collision uncontrollably so in workpiece or retainer.Can be regarded as real-time system basic function be: discharge counter is apprised of the SD data that this discharge counter will write down.To collision situation, to for example each toroidal memory of existence that is configured (storage time, section can comprise approximately last 10 seconds and about whole 100 microseconds to position expectation value and actual value).SPS can be by SPS-FB (SPS-FB=SPS: storer programmable control unit; FB functional part=one section SPS program) any one occurrence is write in the log memory 260.SPS-FB provides a plurality of functions at this, and for example SPS-FB can provide the NC data are together write the possibility in the daily record 260.This SPS-FB also can enclose appended document (File) or can realize by ID and language independent ground when needed.Can on NC, incident be written in the daily record in an identical manner by the NC program.Data keep and can on the PC part, realize.Visual can in container, the realization for example is used for incident is listed in chronological order.When having GDS, data are for example loaded (for example by file transfer) by GDS circularly.Data also can be processed and be stored among the DB 70.Statistical analysis with corresponding chart can be planned, for example in case the regulation machine from confirming former thereby how long stopping.
The advantage of this solution is that also the change that can on the long time period, will be connected to the running parameter of the automation component on the management system 210 by long term data storage 260 charges to daily record (mitprotokollieren).The impact damper of the data volume that reaches 10 terabytes can be set for the long record on meaning of the present invention.By data analysis unit (for example be used for implementing to dispose or the unit 70 of visual function, in data processing unit 210 or in general database server 85); During data buffering or after (yet after the several years) possibly utilize any means/algorithm (maybe repeatedly in succession optimisedly) to check the data of charging to daily record by interface so that derive cognition thus about the state of automated system parts.And then the result who is produced by data analysis set-up not only is stored or is temporarily stored in the long term memory, and after these results are processed according to the data protocol that will use, is forwarded to the system that is connected 85,100,110 by one of interface.In addition, the manufacturing management system that bears Data Update usually can lightened the load aspect the required counting yield.Device 225 is therefore with the interface that acts on swap data between two systems, and these two systems can use different communication protocol.Device 225 (promptly being integrated in the MTX discharge counter in the real-time part of MTX as the part of firmware) also has the function of supervisory organ (Kontrollinstanz); It is to being connected to parts on this equipment, monitoring with regard to its duty like the programmable control device of storer (SPS), numerical control device (NC, CNC), driving regulator and motor, analyzes the duty of these parts and duty is notified to superior system 210,85.
In addition, be connected to the running parameter of the automated system parts on this equipment by second interface in the running hours change, and proofread and correct in working time thus.In addition; Long term data storage 260 is also used the data buffer that acts on data analysis unit 210, wherein analysis result or analyze that intermediate result can be stored in the long term data storage 260 and from long term data storage, read again and further handled by data analysis unit 270.Data from long term data storage 260 can be called by this superior system 85 by the superior system that can be connected on first interface.What can imagine equally is that data storage is configured to can be by the automated system component invocation that is connected to second interface.
