扫描架培训讲义资料重点

电机报警一般都可以从扫描架操作面板进行复位，有的报警需要到传动侧变频器上进行复位。如果在变频器上不能复位，或者刚复位又立即出现的，就需要检查变频器和控制器是否故障。在施胶扫描架上出现过七水分传感器，涂布量传感器报lamp fault，即为卤素灯故障
该报警的出现，就意味着灯泡坏了。可到现场将扫描头错开，正常时灯泡都是亮的，如果不亮就需要更换灯泡。八当扫描架开启时，报photocell sheet break。

点击下一步按钮，就可以进入曲线编辑对话框，（图6为曲线编辑对话框）在此对话框里有五个编辑曲线的命令，常用的是移动顶点。单选移动顶点，勾选显示编辑顶点选项，曲线将显示出来许多控制点如（图7），然后调整影响里的数值后，来一个个拖动控制点的位置，以实现对曲线的更好的拟合。另外也可以利用删除曲线命令来删除不对的曲线。曲线编辑完成后，再点击下一步按钮，将会进入一个新的对话框。那是调整相切线的对话框。
砂纸命令是针对小面积小区域的一种平滑方式，而下面减少噪音和松弛命令则是对整个数据进行的平滑处理。
多边形——平滑——减少噪音进入减少噪音命令框。
减少噪音里有三种参数类型分别是自由曲面形状、棱柱形（保守）、棱柱形（积极）。大多数平滑都用自由曲面形状，对于特别尖锐的数据，可以选用后两种类型进行平滑。平滑极别可以调到第二档，迭代次数可以调整到1，偏差限制到0.2mm。尤其是偏差限制非常重要，影响到数据的真实性。选中显示偏差项目框，将会显示三角形的移动量，这个移动量是相对于使用这个命令之前的位置。
多边形——平滑——砂纸进入砂纸命令框
砂纸对话框的可选项目只有松弛和清除两项，松弛是将表面三角面片数据移动位置与其它面片数据曲率连续。而清除是将表面数据删除，并且改变区域内数据形状来实现数表据表面的曲率连续。具体操作方法就是用光标在粗造区域上涂沫。清除和松驰在平缓区域进行平滑时驱别不太，而在死角，拐点位置平滑时，清除命令更优于松弛命令
填充按扭：选择这个按扭（选中后图标承红色背景）。点击孔的红边上的任何地方，这个命令将会基于曲率、切线、平面的方式，来填充孔。边界整齐平滑的孔，如下图状态，都适合用填充孔命令。
因为真实扫描数据所得的每一个孔，不可能是完全理想状态的孔，所以经常

09a_IQWetendMD_Ash[美卓扫描架培训资料]

In normal production, TARL gets scanner measurement and is in control mode: ---> MPC is controlling FIF setpoint.Machine speed and stock consistency feedforward take place through unit conversions, so no separate ash feedforward control (like ODFF) is needed .In sheet break HB ash (TAHB) is switch to Control mode and TARL is put to Prediction mode. This is shown with arrows in the operator/maintenance picture.Machine speed and stock consistency feedforwards take place through unit conversions:The mass flow value used by MPC (aqbp in g/l) is the “MPC-scaled” value of RMi measurementWhen the output of MPC (=fiaq) is scaled to mill units (l/min), filler consistency or density value is used. So if cons/dens measurement changes, the filler flow setpoint is changed immediately.‘Saturated control handling’Puts TARL into prediction mode if ash error is negative and control output is less than ‘Satur.control limit’.Break recovery time (Min/Max)After sheet break, headbox ash control TAHB is active over certain time.The time is calculated and You can enter min max limits for thecalculation. Calculated time is visible in the right panelTAHB measurement is directly in g/l, so speed information is not needed.When the output of MPC (=fiaq) is scaled to mill units (l/min), filler consistency or density value is used. So if cons/dens measurement changes, the filler flow setpoint is changed immediately. (This is the same calculation as in TARL)Measurement filterConsistency measurement is time domain filtered, before it is used in the control. User can select different filter techniques and set up the filter.Setpoint filterSetpoint changes are smootheded with filter, Purpose is to avoid large setpoint teps in HB ash control (sheet break situation)Setpoint tracking filterWhen no sheet break, ACHB is in prediction mode and setpoint is tracking the measurement. This tracking is smoothed with this exponential filter.TS Ash measurementThick stock ash content is measured with Kajaani RMi in thick stock line.Difference between raw and filtered = derivative controlIn steady state (no TS ash changes) raw and filtered measuremens are the same ---> no correction to FIF setpoint.When raw measurement changes, filtered lacks behind and a correction is made to FIF setpoint.。

A change in themachine speed causes an upset to the majority of control loops on and around the papermachine. There are several quality control loops, which require immediate adjustment whenthe speed of a paper machine is changed. Typically, the variables to be adjusted are the stockflow, the headbox pressure and the steam pressure. Sometimes also the filler and retention aidflow needs some adjustment.To maintain a constant weight as the speed is increased, the stock flow must be increased. Thespeed of the wire must start to increase at the moment when the increased mass flow of fiber isabout to emerge from the headbox. The increased fiber flow into the dryers will also result inan increased flow of water. Once the web enters the dryers it will require an additional dryingcapacity to evaporate the additional water that will be present. Similarly, to maintain forma-tion, the headbox pressure must increase at the same time as the wire speed. Due to differ-ences in the delay when these variables affect the sheet, the variables need to be adjusted atdifferent times in response to a speed change.IQWetendMD uses predefined setpoint trajectories in Coordinated speed changes. When theCoordinated Speed control becomes active, the setpoint trajectory calculation builds targettrajectories, which are read to the MPC optimization. The multivariable predictive controluses the process models of each manipulated variable to each controlled variable. On thebasis of the process models and controlled variable setpoints or setpoint trajectories the MPCcontroller regulates all manipulated variables simultaneously by considering the processinteraction, and finds a good combination of the movements of all manipulated variables todrive the coupled process outputs to follow the setpoints. Loops which are not controlled withthe MPC, such as the Jet/Wire control, use ”pseudo speeds” to ensure that controlled vari-ables change at the appropriate time.2Coordinated Speed for IQWetendMD2NAMING CONVENTIONSThe primary loop tag designation is created from:MID 3 character machine identifierMPCID4–5 character MPC control identifier (MPWE)CSC1 4 character Coordinated Speed identifierMSC1 4 character Thick Stock flow identifierMost parameters can be accessed via direct access ports created by combining the primaryloop tag, pr: MID–CSC1.P:, with the parameter name (i.e., pr:PM1–CSC1.P:rate).

Thespeed of the wire must start to increase at the moment when the increased mass flow of fiber isabout to emerge from the headbox. Similarly, to maintain formation, the headbox pressuremust increase at the same time as the wire speed.The increased fiber flow into the dryers will also result in an increased flow of water. Once theweb enters the dryers it will require an additional drying capacity to evaporate the additionalwater that will be present. The residence time of the sheet in the dryers will also be reducedrequiring a further increase in the drying capacity. This will typically be provided by increas-ing the steam pressure in a single section of dryers (unless the dryers are cascaded).The additional water in the web entering the dryers will require an additional drying capacityat the moment when it enters the section providing moisture control. The effect of the reducedresidence time will require an extra drying capacity at the moment when the machine actu-ally speeds up. The different delays would indicate that the steam pressure is increased in twosteps. However, of these two effects, the additional water in the web has a larger effect and isthe only dynamics, which the IQWetendMD Coordinated Machine Speed will support.IQWetendMD uses predefined setpoint trajectories in the Coordinated speed changes. Whenthe Coordinated Speed control becomes active, the setpoint trajectory calculation builds tar-get trajectories, which are read to the MPC optimization. The multivariable predictive con-trol uses the process models of each manipulated variable to each controlled variable. On thebasis of the process models and the setpoint trajectories, the MPC controller regulates allmanipulated variables simultaneously by considering the process interaction, and finds agood combination of the movements of all manipulated variables to drive the coupled pro-cess outputs to follow the setpoints. Loops which are not controlled with the MPC, such as theJet/Wire control, use ”pseudo speeds” to ensure that controlled variables change at theappropriate time.4.2CONTROL MODE SWITCHINGStandard mode switching strategies will be implemented for the Coordinated Speed Change.The Coordinated speed control is controlling when the following conditions are met:D MPC optimization (e.g. MPWE) is enabled,D Coordinated speed control is in auto mode,D Coordinated speed control is Enabled,D If Abort if sheet break is on and no paper brake in the scannerD If Abort if Grade Change is on and no Grade Change is active. Usually the Auto-matic Grade change is controlling the machine speed directly, and during a gradechange, the Coordinated speed is switched to manual mode, when Grade Change isactivated.V ery little quality improvement is gained by using the Coordinated Machine Speed for smallspeed changes (e.g. less than 1.0 <m/min>). Thus, in order for the Coordinated MachineSpeed to become ”active”, its setpoint must be changed by an amount that is greater than thetunable parameter Activation SP change. Once the Coordinated Machine Speed has becomeactive, it will set the status Coord. Active on, indicating that a coordinated speed change isunderway. The coordinated speed change is synchronized with trajectory calculations, sothat the actual Coord. Active status is switched on prior to the MPC control interval.12Coordinated Speed for IQWetendMDCoordinated speed synchronizationMPC control cycle (n2one, n2one ≥3)Actionn2one – 3Coordinated speed activatesn2one – 2Trajectory calculation executionn2one – 1MPC optimization executionThe Coordinated Machine Speed will remain in an active status until the actual ramping ofthe machine speed setpoint is complete and all pseudo speeds have ended, (if pseudo speedsare used). This condition will be determined by the absolute value for the difference betweenthe Coordinated Machine Speed setpoint and the corresponding deadband parameter Rampover deadband. Once the machine speed setpoint and all pseudo speeds are within this dead-band, the Coordinated Machine Speed will become inactive.4.3SETPOINT TRAJECTORIESWith the help of the MPC controlled controls, the Coordinated Machine Speed changes arehandled as setpoint changes to controlled variables. Normally these Controlled variables areOven Dry Weight, Paper Ash and Paper Moisture. A machine speed change is converted to amass flow change, which is used in the calculation of future setpoint trajectories for Con-trolled variables. By means of these calculated setpoint trajectories, the MPC optimizationknows about the incoming changes in a setpoint beforehand, and optimizes the future controlactions, so that the speed change will not have an effect on the quality variables, such as ovendry weight and moisture. Manipulated variables, like the amount of dry stock, will change atthe correct time according to the identified process models.When coordination starts, the MPC optimization parameters may have new values, like anew horizon and weights (Parameters used during a Grade Change). Therefore, in this changesituation, it is possible to use more/less aggressive controls than in a normal run. Every MPCCore part has its own trajectory module and all required calculations (waiting time, ramptime and new setpoint) are carried out before trajectory modules.Detailed Control Description 134.3.1Trajectory CalculationsWhen the Coordinated speed becomes active, the setpoint trajectory module reads the total waiting time, the ramping time and the new Controlled variable setpoint, and calculates the static setpoint trajectory.Figure 4DQBP setpoint trajectory calculation during Coordinated speedThe total waiting time W.time for MPWE left is calculated when coordination becomes active using the formula (1) with the tunable parameter Wait time for MPWE and using the longest process delay in controlled variables Speedramp wait (sec). The wait time is required so that the optimization part knows about the incoming changes in the setpoint early enough.W.time for MPWE left = Wait time for MPWE + Speedramp wait (sec).(1)The ramping time is calculated using the formulas (2), (3) and (4).The desired reel speed change is calculated 60)(_convReel SPA speed Speed Speed draw diffspeed .−.=,(2)where speed_diff = Reel speed difference [m/s], (MID–CSC1.P:dspeed)draw = reel speed [m/min] / wire speed [m/min], (MID–CSC1.P:draw)Speed SP A = new speed setpoint from the coordinated speed [Cust.

These alarm messages may be disabled by setting theparameter Issue alarms to off status.For a coordinated speed change to be possible, all of the configured interlocks must be satis-fied. Usually this means that the machine speed and all of the dependent controllers are in anappropriate control mode, the coordinated speed is Enabled, and no configured abort condi-tions are present. If any of the interlocks are on, the following alarm will be issued to indicatethe operator that some interlock is on:MP2–CSC1.poss Coord. Speed Change Not PossibleThe alarm will appear on the alarm display and will not clear until the proper mode conditionsare met.Detailed Control Description15 Usually, the dependent controllers must be in automatic mode. In rare circumstances, this may be overridden by setting the parameter Possible when loop to Manual/Auto mode for a dependent loop.If a dependent controller is preventing the coordinated speed change from occurring, the fol-lowing alarm will appear on the alarm display and will not clear until the appropriate loop is put into automatic:MP2–CSC1–ODRL Coord. Speed Change PreventedThis alarm is only issued if the Coordinated Machine Speed loop is in automatic mode. When the modes of all relevant controllers are set satisfactorily, the global monitor output Possible will become on. If coordination is disabled or interlocks in dependent loops prevent the coordination Possible from becoming active, a change to the coordinated speed setpoint will result in an immediate ramp of the machine speed setpoint. The pseudo speeds of all dependent controllers will immediately receive a new target value, without any ramp. Another occurrence related to controller modes involves a situation where modes are satis-factorily set to start a coordinated speed change, but are subsequently changed. Since the modes were initially set correctly and the waiting time has expired, the MPC has already started to change manipulated variables.There are different kinds of situations that need to be considered in an abnormal condition handling.1If coordination is Disabled, a change to a coordinated speed target will result in an immediate ramp of the machine speed setpoint to the coordinated speed target. 2If the Speed coordination switches to manual, the backout speed is the current speed. The worst situation to arise would be if the operator or drive interlocks took the Machine Speed Control out of COMPUTER. Under these conditions, the Coor-dinated Machine Speed would not be able to adjust the machine speed. Thus, the effects of a pending speed change needed to be reversed (or partially reversed if the Machine Speed had already changed). With the help of the MPC control this situa-tion could be handled without any special calculation measures and the MPC would correct any changes already occurred in the manipulated variables after this abnor-mal situation. The worst case that can happen is a sheet break and to avoid that, there is a need to have constrains limits (Maximum action in GC) in the low–level loops so that the MPC cannot control low level loops too fast.3It is also possible that one of the control loops using the machine speed or the wire speed may be placed to MANUAL or their slave loops placed to LOCAL after a coordinated speed change has begun. Since the change has begun, there will be some effects upon the paper quality, either as a result of changes already made which may be reversed, or from changes that could not be made if the coordinated speed change was to continue. In cases where one or more dependent controllers are placed into manual, the new speed setpoint will be calculated using the backout cal-culation. The hidden parameter MID–CSC1.P:bsused (0 = not used) identifies whether to use or not to use the backout calculation. Normally, this parameter is set to zero (backout calculation not used), and in backout situations, the current machine speed is the backout speed. The MPC will correct the changes that have already taken place in the manipulated variables after this abnormal situation.4If coordination is Disabled during coordinatation or if a grade change starts or a sheet break occurs and the coordination abort on a grade change is ON, the backout target is the coordinated speed target. Normally, an Automatic grade change switches the Coordinated Speed to manual, and abort is not needed.。
