- FIG. 1 shows a schematic block diagram of a production plant
- Figure 2 is a schematic block diagram of a production plant and a
- Figure 3 is a schematic representation of steps for the maintenance of a
- Figure 4 is a flowchart of a method for maintaining a
- FIG. 1 shows a schematic block diagram of a production system 100, the production system having a control system 104 and a plurality of machine units 102 connected in series.
- the machine unit 102a is followed by the machine unit 102b
- the machine unit 102b is followed by the machine unit 102c
- the machine unit 102c is followed by the machine unit 102d.
- Each of the machine units 102 processes a product 112.
- the starting point is, for example, a raw material 111 which is processed by the machine unit 102a.
- this processing by the machine unit 102a results in a product 112a, which is then further processed by the machine unit 102b to form a product 112b.
- the machine unit 102c then processes the product 112b into a product 112c, which is then further processed by the machine unit 102d, for example to give an end product 112d.
- the raw material 111, the products 112a, 112b and 112c, and the end product 112d thus describe a material flow which begins in the image in FIG. 1 and ends at the bottom.
- Each of the machine units 102 has a corresponding local data processing unit 118, so that the machine unit 102a has the local data processing unit 118a, the machine unit 102b has the local data processing unit 118b and so on. For the sake of simplicity, these will not be discussed further with regard to machine units 102c and 102d.
- each of the machine units 102 has sensors 114 and sensors 116.
- the sensors 114 detect machine data 122 and the sensors 116 detect process data 108.
- the machine unit 102a has corresponding sensors 114a for detecting machine data 125a and it has sensors 116a for detection of process data 108a.
- the process data 108 characterize the respective product processed by the machine.
- the process data 108a characterize the product 112a that was produced by the machine 102a.
- the process data 108 are transmitted to the central control system 104, which uses the process data 108a to control the entire production system 100, that is to say all the machine units 102.
- the machine unit 102b is referred to as an example as “the given machine unit” and the machine unit 102a as that given machine unit “immediately upstream machine unit”.
- the local data processing unit 118b of the given machine unit 102b retrieves the process data acquired with respect to the product 112a from the control system 104. This is visualized by arrow 120.
- the local data processing unit 118b thereupon evaluates the machine data 122b, which have been recorded locally, on the basis of the process data 108a called up.
- the result 110 of this evaluation is then provided as a display on a graphical user interface 106.
- the production plant 100 is a plant for the production of cement, as is well known to the person skilled in the art from the prior art.
- the machine unit 102a could, for example, serve to pre-shred various raw materials 111 such as limestone, chalk, clay or marl. These reduced raw materials are then fed as product 112a to a mixer, which is given, for example, by machine unit 102b. The mixture in the specified ratio then leads to the so-called raw meal, for example the product 112b.
- the further downstream machine units 102c and 102d could then be used to add any further necessary correction substances, such as bauxite, sand or iron oxide, and further comminution, drying, heating, firing, etc. to produce the actual cement.
- the machine units are generally identified by reference number 102, the addition a, b, c or d in each case denoting a specific machine unit itself.
- the production plant 100 is a plant of the ore or mineral industry. Process steps such as rock crushing and mineral enrichment with the aim of providing mineral concentrate require a large number of machine units 112 which, connected in series, gradually process the raw material 111 into the actual end product.
- FIG. 2 is based on FIG. 1 and shows sections of only the machine units 102a and 102b, the further machine units being omitted for the sake of simplicity.
- FIG. 2 also shows an external server 200, to which the local data processing unit 118b can access with a request (identified by an arrow with reference number 202) and from which the data processing unit 118b in turn receives an answer (arrow with reference number 204) receives.
- the data processing unit 118b has a model, which models the functioning of the machine unit 102b, based on the process data 108a as an input parameter.
- the modeling of the processing that takes place by the machine unit 102b results in corresponding machine data to be expected, which are to be detected as expected by the sensors 114b in operation.
- the local data processing unit 118b could then transmit the machine data thus deviating together with the associated process data 108a to the server 200 by means of the request (reference numeral 202), whereupon the server 200 sends a detailed one Evaluates this data.
- mechanical shafts and bearings used in the mixing process could vibrate or vibrate in a certain way, which is detected by sensors 114b as machine data 122b could be.
- the server 200 could then calculate an exact vibration behavior or vibration behavior of the corresponding shafts and bearings using a, for example, highly computationally intensive finite element calculation, compare it with the real machine data and derive a result from the comparison.
- the server could then provide the result (reference number 204) to the local data processing unit 118b as a meaningful evaluation.
- This evaluation can include, for example, a concrete recommendation for action, such as, for example, operating the machine unit 102b when mixing at a reduced speed, since otherwise damage to the shafts and bearings could result.
- This recommendation could then be transmitted together with the relevant machine and process data as the result 110 of the graphical user interface 106.
- the graphical user interface 106 is part of augmented reality glasses, AR glasses.
- These AR glasses have a camera 212 which, when aligned in the direction 214, is able to read a QR code 216 attached to the machine unit 102b. Using the QR code 216, the AR glasses are then able to clearly identify and also address the machine unit 102b.
- the AR glasses could send a corresponding request to the local data processing unit 118b with the request for maintenance-relevant information.
- a technician looking through the AR glasses now sees parts 208 of the system in his field of vision, the result 110 of the evaluation also being displayed as a graphic text module 206, for example, with regard to the system.
- the insertion can take place unspecifically with respect to the entire machine unit 102b.
- the AR glasses it is also possible for the AR glasses to be able to use the camera 212 to identify exactly which area of the machine unit the user is currently looking at, so that any relevant parts of the result 110 in the graphic only for this area Text module 206 are displayed.
- corresponding components of the machine unit with respect to which the graphic text module 206 provides information, to be highlighted in color, which is shown by the hatching of the component 210 in FIG. 2.
- the technician wearing the AR glasses should thus be able to conveniently examine, adjust or replace those machine areas if, in his opinion, the evaluation results displayed as a graphic text block 206 require such an action.
- a corresponding sequence is again explained below as an example as follows:
- a maintenance technician for example, runs to a machine unit, such as machine unit 102b, which may need to be serviced. He now puts on the AR glasses and, by recognizing the QR code 216, the glasses recognize which machine unit it is.
- a communication channel between AR glasses and the local data processing unit of this machine unit is then set up either automatically or on command from the maintenance technician in order to call up relevant data 110.
- the AR glasses can also contact the control system 104 in order, for example, to call up additional process data, such as process data 108a, but also process data 108b.
- the result 110 contained by the local data processing unit 118b also contains information, such as an indication of those parts which are currently advertised for maintenance. These can be highlighted in the AR glasses and visualized accordingly for the maintenance technician. It is also possible for the local data processing unit to provide step-by-step instructions by means of which the technician can carry out the maintenance of the highlighted parts (if these are highlighted). These step instructions can also be shown on the display of the AR glasses as a corresponding text module 206. If spare parts are used at this point, they can also be identified by displaying a corresponding spare parts catalog and reordered using the AR glasses. The AR glasses can also call up corresponding catalog information from the local data processing unit 118b, but also from an external server such as the server 200.
- the machine unit 102b can be monitored when it is started again, since the corresponding data of the process control system 104 can be visualized in the glasses, possibly together with the machine data 122b evaluated live.
- the maintenance carried out is then stored, for example on a corresponding server, such as the server 200, and the maintenance technician can then continue with the maintenance of the next machine, so that a corresponding maintenance tracking is possible.
- the local data processing unit 118b serves, in particular, to record particularly fast machine data which cannot be recorded or cannot be recorded by the control system 104.
- the local data processing unit is able to combine and evaluate this fast data with the slow process data.
- the technician is thus able to take a closer look at the machine and to recognize problems even faster by providing the evaluation result 110.
- analyzes of the machine design can be carried out here (for example, are ball bearings dimensioned large enough?).
- the local data processing unit 118 models the system. However, other variants are also possible which, viewed individually or in combination with one another and also together with the modeling, can produce the result of the evaluation. In a simple variant, a set of rules could be used here, which defines what for Machine data 114 based on process data 108 are to be expected and how the maximum tolerance ranges are to be seen here. It is also possible to use a machine learning module, so that instead of permanently programming rules, the local data processing unit is able independently to draw corresponding conclusions regarding the results of the evaluation to be output after a corresponding training cycle.
- FIG. 3 shows a further diagram, a machine unit 102a for pre-comminution of material, a machine unit 102b connected downstream for carrying out a thermodynamic process and a machine unit 102b downstream for post-comminution being specified as concrete machine units 102.
- Appropriate sensors are used as process parameters analogous to the discussion of FIGS. 1 and 2, e.g. an inlet temperature, a final temperature, a differential pressure, a grain size distribution and a chemical composition of the product.
- Machine parameters 122 are, for example, a working pressure, a power consumption of the machine, an energy consumption and various dynamics such as force dynamics, pressure dynamics or moment dynamics. This could play a central role, especially in the case of larger, heavy bearings, since depending on the nature of the material to be processed, corresponding oscillations and vibrations can occur, which have a major influence on the processing quality and the mechanical durability of the machine unit.
- the process data While typically the process data are generally transmitted from the respective machine unit to the control system every second, the machine data are recorded at high sampling rates and processed or stored in the local data processing unit.
- the rates are in the range from 100 Hz to several kilohertz.
- Characteristic variables such as frequency spectra, counting frequencies or envelopes can be derived from the machine data, which are then referred to in appropriate models can flow.
- the process data 108a of the pre-shredding machine 102a are included in the evaluation with regard to the machine unit 102b performing the thermodynamic process, the various parameters 122b additionally being used for this purpose to assess corresponding model states.
- model states can be physical or statistical in nature. Assessing the
- the respective result 110 provides model states e.g. in the form of
- the result 110 can then be made available to the corresponding graphical user interface.
- FIG. 4 shows a flowchart of a method for the maintenance of a production plant, with process data and
- Machine data can be called up.
- the relevant machine data are called up by the sensors of this machine unit, the process data originating from the machine unit directly upstream of this machine unit.
- the process data is called up by the control system, which is intended to control the production system.
- step 402 The retrieved process and machine data are then evaluated in step 402, whereupon in step 404 the result of this evaluation is made available for display on a graphical user interface.
- comparisons are thus made, for example, to an optimal state, or data related to each other are grouped and arranged for analysis and support purposes.
- a higher-level system such as a server
- other services can be used, for example, for more in-depth optimization are used, which may then lead to an adaptation of the configuration and / or filters in the context of local data acquisition.
- the local data processing unit with its data on the process and the machine data continues to offer, for example, services itself in order to be able to view relevant information on site depending on the mode (filter), for example by using mobile devices with a data connection such as smartphones, tablets and / or augmented Reality devices such as AR glasses make the relevant information available to the user.
- the deviation of the current state of the function of a corresponding machine unit with an optimal state which is calculated, for example, in the local data processing unit or made available there, can be called up as a deviation, for example in a false color representation.
- the combination of machine data and process data with the ability to access more complex algorithms on site and the flexible display of data on the display device in conjunction with location information thus offers the possibility of being able to credibly present relevant information for a technician.
