Definitions
- the invention relates to process control systems especially for spinning mills.
- Process control systems are now part of certain industries long established state of the art. The question is why these "known principles" are not readily available in the textile industry Let it be realized but only with difficulty, step by step come into use. The answer lies partly in the fact that a process control system is difficult to machine a complex (such as a spinning mill) "imposed” can be. Process control systems are relatively easy introduce where the computer science and process technology be developed at the same time. This is e.g. in the field of Chemical fiber processing (filament spinning) rather the case, see above that was already introduced in the Dornbirn conference of 1981 of process control systems in the filament spinning mill (Lecture by K. Ibounig - “Change of Process control technology through microelectronics ").
- the IT in the spinning plant is in the overall framework automation. Your purpose is ultimately a better one Mastery of yarn production. They are the yardstick Production costs.
- the boundary conditions are from the raw material market, of the local operational conditions and of the yarn buyers determined. The following explanations refer to the conditions in the short-staple spinning mill. An example is the ring spinning of a combed yarn Cotton. But the invention is in other spinning mills and applicable to the manufacture of other end products.
- the spinning process involves the conversion of a natural product with only limited predictable properties in an exact specified intermediate product (yarn). By dividing up Yarn production is in a number of different stages in addition, it is particularly demanding in terms of process technology.
- the added value is on the individual Process stages of the spinning mill unevenly distributed: in the blowroom and the carding is the cleaning effect in the foreground, which primarily has a major impact on the Has running behavior in the final spinning of the fibers.
- the decisive factors for the properties of the finished yarn are subsequent process steps combing and stretching as they the refinement of the raw material and the uniformity of the Serve fiber association. Make these sections of production in today's spinning mill only a limited part of the Value creation, but are for process mastery crucial. Here the benefit potential is mainly limited on the use of inexpensive raw materials.
- the final spinning process is the bulk of the added value. At this point, this is precisely the quality specified yarn, and is at the end of the final spinning checking for "good” or "inferior” (or even "Committee”).
- Fig. 2 shows the personnel requirements in the different Process stages. Operation does not require long training but extremely high reliability. On only confusion between two roving bobbins in the night shift in the worst case, the entire production of several is sufficient Days unusable - and this may happen recognized only when dyeing the finished fabric. Especially older ones Systems require particularly conscientious and attentive Operating personnel.
- a very important component in process control is starting up, changing over and stopping the production line.
- Automation what is widespread in Western Europe today Shutting down the system over the weekend does not only bring costly downtimes, but a pronounced one Restlessness in the process.
- Each time a machine comes to a standstill is a malfunction and after a short time brings more upstream or the following machines from the production cycle.
- the Starting up a spinning plant is always process-related risky. Automation is therefore not a priority such as the automatic startup of the system, but that Avoiding downtimes. Through low-personnel shifts at In the future, it will be possible to start up at night or at the weekend largely avoid.
- Fig. 3 summarizes the functions and requirements for the temporal skills of process control in the spinning mill together.
- This invention is based on a third concept, namely the introduction of new spinning machines with controllable properties for operation with a closed control loop. This also includes troubleshooting by operating robots (Normal case) and operating personnel (exceptional case, repair). This concept means switching to one actual process control. It sets a high degree of Automation and process monitoring ahead.
- Fig. 4 summarizes a corresponding overview of the introduction of process informatics together in the spinning mill.
- FIG. 5 summarizes the requirements for the data transmission capabilities of a network which is required to fulfill the requirements shown in Fig. 3 functions shown is designed.
- Telecommunications is taking part in the development of network standards hardly any consideration for the textile industry. In the Therefore, only products with a more industrial choice are chosen Distribution, already for the necessary duration of use and reliability to ensure. The required hardware components and software drivers are precisely specified and do not have to be more specially developed.
- the invention is in accordance with the latter concept a spinning plant with a process control computer for at least a machine group before, each machine the Group is provided with its own control, which the Actuators of the machine (including any assigned to this machine Auxiliary units) controls. It is at least one Network for bidirectional communication between the Computer and each machine in the group.
- Control commands from the process control computer are in operation System directed to the machine controls via the network.
- Each machine control passes the control commands to the actuators controlled by this control, the Control commands if necessary by the machine control in control signals suitable for the actuators can be converted.
- the control commands can be transmitted directly from Process control computer to the machine controls. However, this transmission can also be carried out via a further device take place, e.g. via a "machine station" of the EP 0 365 901 type described. It is important, however, that neither Process control computer still a transmitting device (such such machine stations) direct access to the Actuators of the machine is granted. Instead, one Change of machine condition, which an intervention in the actuators only require the machine control (and according to the work program effective in this control) become.
- connection of the machine control with its (controlled) Actuators can be used independently of the communication network the machine control and the process control computer and can even be different for different actuator elements (or auxiliary units).
- a machine with a variety of jobs e.g. a so-called Slitting machine
- an autonomous control for each Work place can be the connection between the machine control and the existing actuators via the autonomous job controls can be realized, for example according to DOS 3928831 or according to DOS 3910181 or according to DPS 3438962.
- the signal connection with the machine control on electrical, optical, magnetic, pneumatic, mechanical (or other) signal transmission means.
- any machine control system is able to do that Control commands received from the process control computer into suitable ones To translate (convert) signals for their own actuator elements.
- the process control computer can accordingly a single set of control commands for a given Work machine type, regardless of whether with the process control computer connected machines of this type with the same or with different actuator elements or auxiliary units are equipped.
- the sensor system of the machine preferably comprises at least one Safety sensors, which are used for signal transmission with the Machine control is connected.
- the machine control is preferably continuously capable of using the sensors an image of the state (especially the safety state) of the machine.
- the machine control can then be programmed so that it is only or only then executes a control command from the process control computer if based on the image of the condition of the machine without danger the machine of persons, machines or operating devices can be converted into the new state.
- the "security state" the machine therefore includes both the Safety of human operation as well as that of any mobile operating devices available on the machine (in particular automatic controls) and in elements integrated into the machine. This is of course of particular importance in connection with people who are can move freely around the machine at any time, however also in connection with any mobile devices, which does not change continuously but only occasionally on the Machine, e.g. Transport devices for original material.
- the invention is in one System after our PCT patent application with the international Publication number WO 91/16481 realized, i.e. in a system in which at least one machine control is a Has user interface and the process control computer this user interface for communication with a People or with a mobile machine on this machine can use.
- This arrangement can be relative easily be made sure that in the whole of the calculator controlled system a specific signal a unique Meaning is assigned.
- This can be compared to a system after which the operating support via a system independent of the machine controls, e.g. according to US 4194349.
- the advantages of the combination according to this invention are particularly pronounced when a Process control computer both the operator support and also influences the control of the machines, e.g. in one Doff management system for ring spinning machines, similar to one System according to US 4665686.
- the operator support via the user interface the applicable machine naturally also ensures that the help is offered where it is necessary. This allows also a simplification of the alarm or call system, because in principle, operation is now only possible on the machine concerned must be conducted without first knowing exactly what is necessary Action to be informed.
- the alarm or call system must Of course, still ensure that the operation is about the urgency or the priority of the service call or that the correct accessibility or operator (Help, maintenance, thread break repair, etc.) to the affected machine is called.
- Instructions can be sent to the user via the user interface Be given to the operator to take an action which is not carried out by the machine control itself can be e.g. because the necessary actuators in the applicable machine is not available or not under control of the machine control.
- An example of one such act namely, the decommissioning of a bad working spinning station where the machine control is not directly can intervene in the spinning positions
- the operator can also be asked to do so be certain information (data) in the communication system (e.g. a keyboard). These dates complete e.g. the image of the system in the process control computer, if the appropriate sensor technology in the guided Machines missing.
- the operator is also preferably able (or is even "forced” to cause the generation of a signal which represents the execution of the instruction and this to the machine control or the process control computer communicates.
- the preferred system according to this invention is with a Provide sensors, which the operation of the system without ensures the process control signals of the process control computer.
- the system is as "Conventionally" operated system designed, i.e. she is on the machine level with such sensors and with Such machine controls connected to this sensor system provide that the system without the Process control computer is fully operational.
- control signals generated by the operational process control computer then have an optimizing effect on the otherwise operational Plant, the machine controls of the plant based on the Capable of signals from the associated sensors are to check the plausibility of the control signals at any time.
- a machine control only then executes a control command from the Process control computer from when the plausibility check no contradiction between the control signal (control command) of the Process control computer and those determined by the sensors Condition of the system reveals. Otherwise the machine control will trigger an alarm signal.
- the "control commands" of the Process control computers are usually in the form of setpoints generated or intended to processes or state transitions trigger on the machine (s).
- the system can be operated "conventionally” in the sense that already known controls and Sensors are sufficient to operate the system without the process control computer to operate.
- These controls known today can of course still be improved, but are still as to be considered “conventional” as long as they are able the system is operationally upright without the process control computer to obtain. If the process control computer fails, can do certain functions of the process control computer be taken over by the operator. In this case the possibility of human intervention in the "conventional" Investment control can be provided. But it is also desirable for other reasons, the possibility of individual interventions by the operator in the Provide process flows for the system, even if the Plant as a whole controlled or regulated by the process control computer becomes.

- the frame 210 carries a gate 230 which consists of vertical Rods 232 and cross beams 234 is formed. Rails 236 are mounted on the outer ends of the cross beams 234 and extend in the longitudinal direction of the machine. Any rail 236 serves as a guideway for a trolley train 238 which introduces new coils 240 to the gate 230. details Such a trolley train can be found in EP-43 12 68.
- the gate 230 also includes carriers 242 for supply coils 244, 246, which supply the individual spinning stations with roving.
- the beams 242 are drawn as cross rails, but with this arrangement is irrelevant to this invention.
- in the 16 are the supply spools for each row of spinning stations 212 and 214 arranged in two rows in an inner row 244 near the median plane ME and an outer row 246, which is away from the central plane ME is.
- the cross members 234 also carry one on each machine side Rail arrangement 248 or 250, which serves as a guideway for a respective mobile robot 252 or 254 is used.
- the Robot 252 or 254 therefore runs between the outer supply coil row 246 and those carried by trolley train 238 new coils 240 and above the respective control unit 226 or 228.
- the robot 252 is for operating the two supply coil rows of the gate, as in our PCT Patent Application No. PCT / CH / 91/00225 has been declared. This robot is designed for sliver handling in such a way that after changing the spool in the gate, the fuse of the new one Bobbin is threaded into the drafting system by the robot.
- FIG. 17 shows an example of the layout of the spinning room one Ring spinning system by a robot after PCT patent application No. PCT / CH / 91/00225 is operated.
- the diagram 17 is intended in particular to explain the delivery of spinning machines with original material to be processed serve.

- Spool change operations are preferably performed after a predetermined one "Change strategy" executed, an example of which in PCT Patent Application No. PCT / CH / 91/00225. According to this strategy, the change operations become alternate on one or the other side of the machine carried out to the workload of the control devices 226,228 (Fig. 16). Because it is necessary when re-threading the drafting system, a bobbin change operation every time coordinate with a thread break repair, so that the control unit 226 or 228 should always be present at the affected spinning positions. Of course, this means that the control unit is used not available from other spinning stations, though if necessary, other faults (such as a thread break repair require) occur at these other spinning positions.
- the preferred machine arrangement therefore comprises at least two operating devices (Fig. 16), one on each machine side assigned.
- an operating device for cooperation with a bobbin change operation on one machine side can be delegated is the control unit on the other side of the machine, the spinning positions to operate that do not require a bobbin change operation.
- the request (in the form of a signal) to advance of a fully loaded trolley train from the Transport device to a specific ring spinning machine preferably from this machine itself (for example according to EP-392482).
- the positioning of this trolley train compared to the ring spinning machine then depends on the overall arrangement from. For example, it could be provided that an entire machine side each time with trolley trains is occupied, after which bobbin changing operations by the robot be performed.
- the information regarding the Gate positions which are to be occupied from these trolleys, should be in the ring spinning machine or in the robot (rather than in the central control 514 of the transport device) his.
- each trolley train must be done in groups in a suitable position opposite the ring spinning machine be placed and locked.
- controller 514 of FIG Transport device and the control of the ring spinning machine to define so that the movements of the trolley train this interface from the ring spinning machine control be adopted (e.g. according to EP 392482).
- the appropriate location information can either from the robot to the Ring spinning machine can be delivered or they can in the Ring spinning machine control system and robot be transmitted.
- Triggering a bobbin change operation can be done by the Ring spinning machine either by time or (preferably) according to the amount of sliver delivered (i.e. depending machine speed).
- a spinning machine needs a transport device not only for the supply of the original material but also to transport the product of the spinning machine itself.
- Most modern ring spinning machines today are with two Conveyor belts equipped according to Fig. 18. Each row of spindles is assigned its own pin provided with a pin.
- the Empty sleeves are each on a pin by the movement of the Belt in the longitudinal direction of the machine and the doffing machine thereby fed to the spinning stations - the same or different pins attached to the belt are used to remove the full Kopse after being removed from the spindles by the doffing machine become. Examples of such systems are described in US 3791123; CH 653378 and EP 366048 to find. Newer systems based on the basis of the so-called peg tray, e.g. out can be found in European patent application No. 45 03 79.
- Transport devices e.g. for transporting cans to the or for the further transport of packages from the rotor spinning machine.
- Transport devices e.g. for transporting cans to the or for the further transport of packages from the rotor spinning machine. Examples of such systems are in DE 4015938.8 from May 18, 1990 (can supply) or DOS 4011298 and DOS 4112073 (Package transport system).
- the actuators of the machine include both the one and the attached elements and aggregates.
- the actuators for the built-in elements includes at least drives for the Spindles, the drafting systems and ring bench.
- a modern concept System (single drive) for driving the spindles, Ring bench and drafting systems of a ring spinning machine is in EP 349831 and 392255 shown what for each spindle and also a separate drive motor for each drafting system is provided.
- the most used drive system today (Central drive) for the ring spinning machine includes a main motor in the drive head of the machine and Transmission means (e.g. longitudinal shafts, belts or gears), the driving forces from the main motor to the drive elements transferred to.
- the actuator system for the built-in elements also includes the drives of the transport devices for cops (e.g. after DOS 3610838) or for empty sleeves in the attachment (e.g. according to WO 90/12133).
- the attached auxiliary units naturally include both Robots 226,228 and 252,254 as well as transport trolleys 238, which are temporarily positioned on the machine. Further Examples of such units are cleaning robots, blowers or other mobile machines e.g. for the runner change.
- Some of these units have their own drives (mobile automatic controls). Others may not have their own Drive but are from one of the machine on or installed drive depending (see e.g. the trolley drive 16 to 18 of WO 90/12133) or a drive according to European patent application No. 42 11 77.
- the drives these auxiliary units are also called the actuators To consider spinning machine provided by the machine control can be influenced.
- Important actuator elements are those that are used for "decommissioning” serve a spinning station, where “lay still” here “as to shut down effectively producing spinning station " is. In most cases, when one is shut down, one becomes individual spinning station not all working elements of this Spinning station brought to a standstill, but spinning wirc interrupted in this spinning station. For example by cutting off the material supply and / or by deliberate Generate a thread break happen.
- a largely automated machine e.g. the rotor spinning machine
- the drive on the feed roller is interrupted to ar the material supply to prevent the opening roller or the rotor of the spinning station.
- it can also be a so-called quality cut in the quality control of the spinning station or winding station be carried out to interrupt the thread flow.
- Such a rotor spinning machine or jet spinning machine "Cut" by deliberately interrupting the feed material caused.
- match clamp to interrupt the material supply will be important for all machine types, where that Original material delivered to the spinning elements via a drafting system is because usually the parking of a single Position of a drafting system is impossible.
- the match clamp of the individual spinning positions can of course also ever an actuator can be assigned. These are can then also be operated from a central machine control. Examples of such match clips are in EP 322636 and EP 353575 to find.
- Today's conventional ring spinning machine usually has a central microprocessor control, the appropriate control signals for the central drive system (usually by controlling a frequency converter) generated.
- a single drive system can e.g. a "distributed" Control according to EPO 389849 include.
- Novel spinning machines Rotor or air spinning machines
- the mobile auxiliary units each have their own autonomous Control - see e.g. EP 295406, EP 394671 or EP 394708 (Obj. 2083). Although these controls work autonomously, each subordinate to the machine control hierarchically. At an upcoming doffing e.g. become the robots 226,228 through the coordinating machine control from the Working areas of the automatic doffing machines 222,224 ordered away (e.g. according to DOS 2455495).
- the controller 514 of FIG. 17 is also a "machine controller" to consider, i.e. the transport device, organizationally, which connects two processing stages can be considered as a “machine”. this applies not if the device in question is in a machine installed or hierarchically subordinate to a machine control is.
- the rotor spinning machine e.g. has been equipped with sensors for a long time, which shows both the condition of the individual spinning station and also reflects the quality of the yarn produced therein (see EP 156153 and the prior art mentioned therein. For modern monitoring - see ITB yarn production 1/91, pages 23 to 32.4). Similar systems are also for that Filament processing in the false twist texturing machine developed - see e.g. DOS 3005746.
- the winding machine which processes the cops of the ring spinning machine into cross-wound bobbins, is already with sophisticated sensors provided - see e.g. DOS 3928831, EP 365901, EP 415222 and US 4984749.
- the corresponding sensors can be used as the safety sensors of the corresponding machine.
- the sensors may be on a neighboring machine or a Transport system must be installed. It is important that the sensor signals directed to the appropriate machine control become.
- the control of the entire system is designed so that the Processing stages are "chained". Provided the transport between the processing stages is automated Signals from a "source” (delivering machine) and one "Sink” (machine to be supplied) from the control of the Transport systems are processed to a "driving order", which is then issued to a transport unit (provided of course, that a free loaded transport unit is ready). Where certain operations are not yet automated an operator is required.
- a process control computer overlays to a process control level to build. 19 shows a corresponding one Execution, which is a modification of the system according to FIG. 14 is executed.
- FIG. 19 shows schematically the connection of the process control computer with individual machines. The illustrated thereby However, principles also apply to the connection with further or with all machines of the overall system.
- Fig. 19 shows schematically a possible variant of the architecture for a process control with the host computer 340, the network 350, the computer 390 and the computer 410, which previously held together 14 have been described. Every computer 340,390 still has the memory assigned to it 343.345 or 391 and driver 347.349 (Fig. 14) or 393.394, (Fig. 14) 395,396 (Fig. 14), with certain elements in Fig. 19 are no longer shown since they can be seen from FIG. 14.
- This process control can be for the entire system or just for part of it (e.g. for the spinning room according to Fig. 9 or 17 are provided.
- Additional drivers 412 and 416 determine the necessary ones Interfaces for communication between two additional computers 414 or 418 and the network 350. Both additional computers 414,418 are provided with drivers (not shown), which are the interfaces between the respective computers 414,418 and display and controls, only those with Display 420 and control 422 connected to computer 414 are shown are.
- the computer 418 controls an air conditioning system which controls the hall air-conditioned, which is what the computer 390 and 410 controlled machines (among others). This facility has of course nothing to do with the processes to do directly, but has a decisive influence on the environment, in which these processes must be carried out and accordingly the results of these processes.
- the air conditioner is provided with a sensor system, which is schematic in FIG. 19 is represented by a sensor 424.
- the computer 414 controls a data acquisition system, which the machine controlled by the computer 390 is attached.
- the data acquisition system comprises a sensor system which is shown in FIG. 19 is represented by sensors 426 and 428.
- the sensors of the acquisition system acquires measurement data about states in the machine controlled by computer 390, but delivers the corresponding Output signals (raw data) are not sent to the computer 390, but to the computer 414.
- This can (but must not) have a connection 430 to the computer 390 which is explained in more detail below, but provides the won Raw data nevertheless via the network 350 to the computer 340.
- the process control computer 340 can now control commands via the Network 350 to computer 390 and / or to computer 414 send.
- control commands are received by computer 414 and affect the data collection system is not Communication over connection 430 necessary. If such Commands, however, must relate to the actuators of the machine itself it via the connection 430 to the machine control 390 are forwarded if they are received by the computer 414 become.
- This arrangement is not desirable because of the Process control computer 340 preferably directly with the computer 390 communicates. The arrangement is not from the invention excluded and could prove necessary, if the "cooperation" of the data acquisition system is necessary is to use the results obtained from its data in Convert control commands for the machine. This could e.g.
- Fig. 19 also shows another computer 432, which the Computer 390 is assigned.
- Computer 432 controls e.g. an operating device, which of the machines controlled by computer 390 is constantly assigned.
- the calculator 432 cannot directly, but only via the computer 390 with the process control computer 340 communicate.
- the computer 432 receives control commands from the computer 390 and otherwise works as an autonomous unit. It controls its own drives 434,436 and has its own sensors 438,440.
- Sensor 438 is used to monitor an operating state the autonomous unit (the control unit) provided - the sensor 440, however, monitors a state the machine controlled by computer 390.
- the raw data of the Accordingly, sensors 440 become continuous or intermittent forwarded to the computer 390.
- a sensor 442 provided in the machine could be used Monitoring of a state of the autonomous unit is provided become. Its raw data would not have to be forwarded to the computer 432 but would be the control commands addressed to him influence.
- connection 444 between the computers 390 and 432 must do not exist continuously.
- a suitable connection between the control of a ring spinning machine and one of these attaching robots is in ours European Patent Application No. 394671.
- Computer 432 (like computers 390 and 414) can have its own Display or control elements are provided that but are not shown in FIG. 19.
- a machine disconnected from the process control computer is subordinate full control of the operating personnel. It can then e.g. Maintenance work or attempts (regardless of guided system).
- a "decoupled” machine is preferably from the process control system not completely isolated - it continues to report their respective status information to this system, responds but no longer on their respective control commands Host computer.
- the "switch” works in a certain way Sense as a “diode” which only signals in one direction.
- Switching means e.g. in connection with the machine control provided
- the actuator system or predetermined elements thereof
- Means can therefore be provided for a decoupled Continue operating the machine in various ways e.g. in “normal operation” (but without the function of the process control computer) or in “service mode". It could even various "keys" are provided to the machine set in one or the other operating state.
- Every machine control as well as the process control computer saves an image of the respective controlled system part from.
- the process control computer has much more data edit as a machine control controlled by him. Since the processing (interpretation) of this information is a certain Takes time, cannot be assumed be that a control command from the process control computer current state of the controlled machine is adequately taken into account. This is particularly related to the security status important to the machine. The responsibility" for safety is therefore at the machine control level set.
- the safety essentially depends on the movements of the machine parts from. These movements determine geometrically definable “Fields” or (three-dimensional) "rooms". It is therefore possible to take responsibility for a particular controller for a given security field or security room assign. This principle is explained below with reference to FIG. 20 explained in more detail, using two-dimensional fields as examples being represented.
- 20A shows the simplest example - the "security field" 550 of a machine 552 envelops the machine with one given distance, which is the maximum extent of movable machine parts (e.g. Dofferbalken 222,224, Fig. 16) is taken into account. Within this security field can all movable, subordinate to the machine control Elements move (e.g. also operating robots).
- the "security field" 550 of a machine 552 envelops the machine with one given distance, which is the maximum extent of movable machine parts (e.g. Dofferbalken 222,224, Fig. 16) is taken into account.
- this security field can all movable, subordinate to the machine control Elements move (e.g. also operating robots).
- Fig. 20D shows a variant where a machine 570 a "changeable" security field 572 is assigned, e.g. because this field corresponds to a movable extent 574 includes a mobile robot.
- a second element e.g. a blower
- a "Dodge duty" for one or the other movable Element to be predetermined.
- the functions of a host computer should be compared to the Functions of a data acquisition system are delimited, whereby the master computer can also perform recording tasks.
- the data acquisition has the task of making a meaningful Generate overview. Possibilities are for example in Article "Process data acquisition in ring spinning - application and further processing of the process data from USTER RINGDATA shown on a practical example "by W. Schaufelberger. The article was published at the Reutlingen spinning mill colloquium presented on 2/3 December 1986.
- the function of the host computer in the spinning mill depends on the task set by the user.
- This Function can e.g. consist of the basically autonomous operational system based on a predetermined strategy optimize.
- Another task can be the plant Operable over long periods without operator intervention maintain what is both dispositional as well Maintenance tasks included.
- the process control computer therefore preferably has its communication network or its communication networks Access to the raw data of the sensors in the system that are important to him or in the machines he controls.
- the raw data contain the full information of a particular (for that Process control system important) sensor, possibly prepared in such a way that misinterpretations are avoided.
- a particular (for that Process control system important) sensor possibly prepared in such a way that misinterpretations are avoided.
- the thread break sensor on a particular Spinning station signals a thread break - off this signal can only be concluded that the thread is broken if the spinning station (or the machine) is "in operation" is what is caused by another signal (or by further signals) must be taken into account in the signal processing.
- the invention is based on a clear "division of tasks" between the process control system (process control computer) and the machine controls.
- the process control system is required to fulfill these tasks (the process control computer) Information regarding the operating status for every job in the system. This places high demands on information transfer capabilities the network or networks between the machines and the calculator.
- the process control system must not continuously about the current status of the system be informed, but is facing delays in insensitive to data transmission, provided that this Delays show trends early enough that the process control system intervenes if necessary can.
- the process control computer has access to the Raw data from the system's sensors, but no direct data "Control Powers”.
- the process control computer issues control commands in the sense of target values or target status changes (e.g. "early spinning off") to the machine control ab, but these commands only after processing by the own control program and taking into account the current depicted state of the elements controlled by it and Passes aggregates as control signals to the actuators.
- the machine control software must be that of the host computer Check received control commands for plausibility. This applies to all aspects of controllable processes, so that the machine control system receives an "authorization” can "question” a control command if this Command with the image stored in the machine control of the machine condition does not match.
- the software the machine control can e.g. be interpreted in such a way that she only follows such a control command if it is confirmed by input from the staff or if a machine condition permitting the intervention is reached.
- the host computer can transfer these settings to the machine controller (s) influence the setpoint values given and on adjust the environmental changes. If e.g. an analysis shows that the number of thread breaks in the start-up phase of the The realistically expected (empirically over time) determined values, the "speed curve" (Fig. 21) the machine can be adjusted to the number of thread breaks lower again in this phase. This curve defines the Setpoints for the speed of the main drive motor (or the individual spindle motors) via the cop assembly. (see e.g. CH 1374/91 - cf. DOS 4015638).
- the host computer can Instruction via network 350 to the affected machine send this instruction on the control surface the machine must be displayed. If the adjustment of the Operating conditions is absolutely necessary, the host computer at the same time a warning call (e.g. after PCT patent application No. WO91 / 16481) to the appropriate personnel to the most suitable person on the need / type of required Draw attention to new hires (alarm system).
- a warning call e.g. after PCT patent application No. WO91 / 16481
- the communicative machine is a machine that is The communicative machine:
- FIG. 22 schematically shows a machine 580 with its own Control 582, which controls machine actuators 584 and messages (Signals, data) from the machine sensor system 586.
- This Control is in the form of a computer with suitable Programs (software).
- the machine is also with one so-called "communication board” 588 provided with the Controller 582 is coupled and has a connecting means, to couple the 588 board to the communication network should serve.
- the connection means can e.g. to connect with a coaxial cable or light guide or with a twisted Double wire are formed.
- the network is called a bus executed and is carried out according to the so-called “polling procedure” (Time sharing) operated, after which the connected communication boards queried in sequence or supplied with data become.
- polyling procedure Time sharing
- the communication board 588 preferably comprises a memory, which acts as a buffer for the data supplied or the data to be sent.
- This buffer memory is preferably "oversized" compared to normal operation and can therefore accumulate data about a predetermined Save period longer than the one specified by the system Polling interval lasts.
- the communication board also has that aforementioned drivers (programs). The board issues data the memory to packets of data together over the network can be sent to the host computer.
- the process control computer and the network are often (mostly) supplied and installed by a system supplier. There are then two ways to determine the Interface between the one supplied by the machine manufacturer Elements and the system. After the first option is the interface between the 588 communication board and controller 582. However, this can cause problems in the Adjust the board to the control.
- the communication board 588 and machine control by the machine manufacturer adapted to each other and prepared for connection to the system. To do this, it is necessary to contact the system supplier suitable protocol (transmission mode) and a common one "Object directory" to be agreed, the latter directory the information received of the signals defined. In order to the process control computer and the machine control are mutually exclusive able to communicate.

- Nur die Stillstände, nicht aber deren Begründung werden automatisch erfasst. Für die Störungs-Statistik bedarf es weiterhin auf Mitwirkung des Bedieners.
- Der Materialfluss ist nicht kontrolliert. Das Fortpflanzen eines Fehlers lässt sich nur mit Mutmassungen verfolgen.
- Technologisch bedeutsame Eingriffe wie das Beheben von Fadenbrüchen oder das Entfernen von Wickeln werden nur indirekt erfasst, beispielsweise über die Stillstandszeit der Spinnstelle oder der Maschine.
- Schliesslich zeigt die Statistik lediglich die Vergangenheit auf. Sie lässt mannigfaltige Fehlschlüsse zu. Ein rasches Eingreifen, Voraussetzung für eine zeitgerechte Fehlerbehebung, erfordert nach wie vor die Kontrollrunde einer aufmerksamen Bedienungsperson.
- Das Ausweiten der Produktionsplanung und -steuerung in die Produktionslinie hinein bis zur einzelnen Prozessstufe und Maschine, gleichbedeutend mit einer Einführung der Informatik von oben nach unten.
- Das Ausgestalten der Qualitätsüberwachung mit Einbezug der Materialflussüberwachung zu einer vollen Prozessüberwachung. Dieses Vorgehen entspricht einer Weiterentwicklung der bekannten Systeme zur Betriebsdaten- und Qualitätserfassung.
- Die Prozessregelung selbst ist auf höchste Betriebssicherheit, die damit verbundene Bedienerführung (Alarme) dagegen auf grosse Geschwindigkeit und hohen Daten-Durchsatz angewiesen. Beide Funktionen des Netzwerks haben unmittelbaren Einfluss auf den Prozess-Ablauf. Da die regelmässigen Kontrollgänge des Bedieners entfallen, wird eine moderne, stark automatisierte Spinnereianlage auf ein gut ausgebautes Alarm-System absolut angewiesen sein.
- Eine umfassende Verdichtung und Auswertung der Sensor-Signale, etwa als Spektrogramm, lässt sich wegen der erforderlichen Rechenkapazität nicht mehr in jeder Maschinensteuerung vollziehen. Eine leistungsfähige Qualitäts-erfassung muss deshalb Zugriff haben auf die Rohdaten direkt ab Sensor. Eine vorherige Verdichtung durch eine lokale Auswerte-Einheit macht eine künftige Erweiterung der Funktionen äusserst aufwendig. Die Übertragung von Rohdaten ist zwar nicht zeitkritisch und erträgt Kompromisse in der Zuverlässigkeit, erfordert aber einen grossen Daten-Durchsatz.
- Die praktische Erfahrung mit handelsüblichen Schnittstellen zeigt, dass für die Anwendung nur noch mit einem Zehntel der theoretisch verfügbaren Übertragungsleistung gerechnet werden kann. Der Rest wird für die Selbstüberprüfung, die Steuerung des Datenverkehrs und als Reserve für Spitzenbelastungen benötigt.
- einem Prozessleitrechner für mindestens eine Gruppe der Maschinen der Anlage,
- einer autonomen Steuerung für jede Maschine dieser Gruppe,
- einem Netzwerk für die bidirektionale Kommunikation zwischen dem Prozessleitrechner und den autonomen Steuerungen, wobei Steuerbefehle vom Prozessleitrechner an die Steuerungen über das Netzwerk übermittelt werden können,
