PWM controller 578 receives digital controlled signal, and this digital controlled signal is transformed into analog control signal.Particularly, PWM controller 578 produces analog control signal, and this analog control signal has and the proportional pulse width of the value of digital controlled signal.
Damping control
As stated, the damping of this control damper 304 of subcontrol 305 controls.Particularly in one embodiment, subcontrol 305 produces the control signal of the damper 304 that is used for it according to the measurement signal of the acceleration/accel of expression arm 212.More particularly; Subcontrol 305 keeps the control algorithm of suitable cleaning pressure to produce control signal between cleaning mechanism 86 and conveyor belt 82 according to attempting; So that reduce the vibration effect that causes by bigger band defective, and reduce to 82, the abrasion action of cleaning mechanism 86 and other mechanism part.
In the working process of being with cleaning mechanism 86, band cleaner arm 212 and inaccuracy are along the shape of conveyor belt 82, because band cleaning mechanism 86 can not react the variation generation of conveyor belt 82 immediately.Although conscientiously make, the surface 84 of conveyor belt 82 can not be smooth fully.Unevenness with 82 causes on the top 260 of doctor blade 214 and the variable in distance between with 82, because band cleaning mechanism 86 can not produce reaction to this variation with 82 immediately.Distance between top 260 and belt surface 84 also receives the influence of belt sag, bigger band defective and friction.Belt sag will cause the relatively slowly motion (for example a few Hz) on belt surface 84 and top 260.But, bigger band defective causes the rapid movement (for example tens or hundreds of Hz) on top 260 usually, because top this bigger band defective of bump.And even without bigger band defective, the friction between top 260 and belt surface 84 causes top 260 to be pushed open from surface 84.
Control damper 304 has the damping of being represented by damping coefficient c.In one embodiment, damping coefficient c is linear with respect to the electric current of the control signal that imposes on control damper 304.The software of subcontrol 305 makes treater 558 select from obtainable status signal (for example displacement signal, speed signal, acceleration signal, peak signal, average value signal and rms signal) through signal selector 574, and confirms to impose in order to obtain suitable damping the control signal electric current of damper 304.
The status signal that is used to control damper 304 by subcontrol 305 can be the one or more status signals that impose on signal selector 574.In one embodiment, subcontrol 305 produces control signal according to the displacement signal of deriving.But, it will be appreciated by those skilled in the art that one or more other status signals also can be used for other bulk material processing equipment 6 or other band cleaning device 80 embodiment.And, should be known in because in the present embodiment displacement signal is calculated or derived by acceleration signal, so displacement signal maybe be corresponding to actual displacement, but with the proportional value of actual displacement.
Through mathematical analysis and a large amount of tests, confirm when control signal and status signal have concerning shown in Figure 61-64, will obtain suitable result.It will be appreciated by those skilled in the art that also other shape or figure can be arranged.
Shown in the instance of Figure 61-64, such as control signal C reaction, status signal is depended in damping.Control signal C has and the corresponding minimum value C of minimum damping that is used for the fail safe characteristic 1Control signal C also has and the corresponding maxim C of maximum damping that is used for safety and stabilization system 2Minimum value C 1With maxim C 2Can confirm by the data sheet of damper 304 and the analysis of bulk material handling system.
Figure 61-64 has further represented system parameter S 1, S 2, S 3And S 4System parameter S 1, S 2, S 3And S 4Corresponding to for example acceleration/accel, speed or the displacement of status signal value.In one embodiment, subcontrol 305 is controlled damping according to the displacement state signal, so system parameter S 1, S 2, S 3And S 4Corresponding to each shift value.As shown in the figure, displacement is represented on the x axle, and the electric current of control signal is represented on the y axle.Therefore, in one embodiment, 0 position on the x axle is in initial position corresponding to band cleaner mechanism 86, and wherein doctor blade 214 engages with belt surface 84.And the positive displacement value is corresponding to being with 82 doctor blade 214 pushed open, so mechanical energy is from being with 82 to pass to cleaner arm 212.On the contrary, the negative displacement value corresponding to 82 return it initial position, and band cleaner arm 212 waits through damper 304, friction and discharges mechanical energy.Through changing system parameter S 1, S 2, S 3And S 4, can obtain cleaning efficiency, blade abrasion and the arm/frame vibration of varying level.
In actual installation, technical personnel rule of thumb, the characteristic of the material of system physical size, band characteristic and transmission is provided with system parameter S 1, S 2, S 3And S 4Technical personnel can analyzing system performance and change coefficient S 1, S 2, S 3And S 4, so that improve this time for the most important parameter of this special purpose.For example, because heavy rain, the material of transmission possibly become wet and become sticky.Therefore technical personnel can determine temporary transient increasing to be applied to the pressure on the belt surface 84 by doctor blade 212.In order to realize this purpose, technical personnel can increase minimum value C 1Thereby, the minimum value of increase control signal.
In addition, control signal figure does not need symmetry.In some cases, asymmetric control signal figure can prove very favourable.The reason of this performance is when the right side has littler slope, and the mechanical energy that is absorbed by external force is lower, because it is lower to connect factor.When the left side had more precipitous slope, the mechanical energy that is dissipated in the environment was higher, because it is higher to connect factor.In one embodiment, maker and technical personnel after a while can be that purpose is selected controlled variable C with the spectral component that reduces in the displacement error 1, C 2, S 1, S 2, S 3, S 4Through signal is transformed into frequency domain (Fourier conversion) from time domain, will keep energy content.This is the direct result of Wiener Khintchine theorem (power spectrum density of the steady random processing of broad sense is the Fourier conversion of corresponding autocorrelative function).Therefore, through analyzing the displacement error spectrum in the frequency domain, can select to reduce the parameter of error.In order to select parameter like this, bulk material processing controller 12 can be selected data, and can carry out the algorithm that is provided with described below, so that confirm to reduce the controlled variable of displacement error.
The setting of damping control
Figure 65 has represented to be used to be provided with system parameter C by each subcontrol 305 1, C 2, S 1, S 2, S 3And S 4Method, these system parameters C 1, C 2, S 1, S 2, S 3And S 4Be used to produce control signal.Subcontrol 305 selects to be used for system parameter C in piece 602 1, C 2, S 1, S 2, S 3And S 4First class value.For example subcontrol 305 is can the selective system parameter following: S 1=-2mm, S 2=-1mm, S 3=0mm, S 4=5mm, C 1=C Min, C 2=C MaxIn piece 604, subcontrol 305 is provided with this subcontrol 305 with selected parameter, and the data of collecting about status signal from subcontrol 305 are used to be provided with circulation.In one embodiment, subcontrol 305 is recorded in the displacement error x (t) that is provided with in the circulation.And in one embodiment, it is 1.5 seconds that circular in definition is set, and it is even as big as comprising by with 82 the complete Energizing cycle of lax at least one that causes.For an embodiment of conveyor belt cleaner 80, belt sag is the excitation with maximum cycle.Other excitation for example rubs or the band defective has the shorter cycle usually.But, should be known in that can select difference that the cycle is set, it constitutes the interested maximum excitation cycle for other embodiment of conveyor belt cleaner 80 or for other bulk material annex 6.
Subcontrol 305 in piece 606 is by the selected data value of assessing the cost, and this value provides to be worked as based on the selecting system parameters C 1, C 2, S 1, S 2, S 3And S 4The measure of effectiveness value of bulk material processing controller 12 during work.In one embodiment, the subcontrol 305 that is used for each displacement error x (t) calculates its discrete quick Fourier transformation (FFT) f x[i] wherein i is harmonic number.Then, subcontrol 305 is for each f x[i] set of calculated is defined as the cost function of root of mean square base value:
R x = ( Σ i = 0 n f x [ i ] / n ) 1 / 2
Wherein, n is illustrated in f xThe number of the relevant harmonic wave in [i].In one embodiment, the number of relevant harmonic wave is 55 times of excitation frequencies.But, for easy for calculation, in less embedded system n=64,2 minimum time power, it is greater than 55.
In one embodiment, subcontrol 305 is attempted the selective system parameters C 1, C 2, S 1, S 2, S 3And S 4, make the overall displacements error reduce, so that make doctor blade 214 keep the surface 84 of suitable bias voltage against conveyor belt 82.But, can design other method to set up of attempting to reduce response time or toning, like this, subcontrol 305 is arranged to consider to handle certain type bulk material the prior others of operation of annex 6.For example, when the purpose of method to set up was the minimizing toning, cost function can be replaced by new cost function, and this new cost function is defined as:
R x＝max(|x[i]|) i＝0...n，
Wherein, max () extracts peaked function from the absolute value tabulation of displacement error x.
Then, subcontrol 305 writes down the value at cost of calculating and relevant group selected parameters C in piece 608 1, C 2, S 1, S 2, S 3And S 4Then, subcontrol 305 determines that in piece 610 whether carrying out another is provided with circulation.In one embodiment, subcontrol 305 is through being used for system parameter C 1, C 2, S 1, S 2, S 3And S 4Probable value come iteration, and another is provided with circulation when residue is also selected repetition during a probable value.In another embodiment, subcontrol 305 comes iteration through probable value, up to satisfying the special cost value or all testing up to all values.For example, subcontrol 305 can be arranged in case one group of parameter causes error (cost) just to stop when being lower than the value of fixing limit.
In piece 612, subcontrol 305 is according to their relevant cost value R x[i] selects one group of parameters C 1, C 2, S 1, S 2, S 3And S 4In one embodiment, subcontrol 305 attempts to reduce cost or displacement error x (t), therefore selects and this minimum cost R xOne group of parameters C that [i] is relevant 1, C 2, S 1, S 2, S 3And S 4But should be known in that for other cost function or other embodiment subcontrol 305 can attempt to make bulk material to handle the value at cost maximum of some aspect of annex 6.In this embodiment, subcontrol 305 can be selected the one group parameters C relevant with this maximum value at cost then 1, C 2, S 1, S 2, S 3And S 4
Although subcontrol 305 can be carried out the method for Figure 65 so that initial setting up system parameter C 1, C 2, S 1, S 2, S 3And S 4But subcontrol 305 also can respond other incident and carry out this method.For example, technical personnel possibly require subcontrol 305 to carry out the method to set up when mode of operation changes.For example, technical personnel possibly require the variation of variation, the humidity of the new conveyor belt of subcontrol 305 response, new transmission material, speed to wait and carry out method to set up.And subcontrol 305 can periodically change controlled variable C a little 1, C 2, S 1, S 2, S 3And S 4, whether better result is provided so that check one group of new controlled variable.
Through operation method to set up in simulation environment (for example SciLab, Octave or Matlab), can confirm for the mechanical parameter that in simulation, uses, C 2=C Max, C 1=C Min, S 1=S 2=-1mm, S 3=5mm, S 4The controlled variable of=10mm can be provided for the suitable result with an embodiment of cleaner 80.Therefore, these values are in one embodiment as acquiescence control group.
Safety management
Having represented among Figure 66 can be by the method for managing security of master controller 500 execution.Although Figure 66 is the step of sequential series with this method representation, it will be appreciated by those skilled in the art that some embodiment can be with the different order execution in step, and can carry out particular step with parallel or pseudo-parallel mode.In piece 630, master controller 500 receives the motor message of the motion feature of expression arm 212 from subcontrol 305.For example, master controller 500 can receive one or more acceleration/accels, speed, displacement, peak value, aviation value and/or the RMS status signal from subcontrol 305.
Whether then, master controller 500 can confirm in piece 632 whether the motion of arm 212 can be accepted, perhaps will take some protection action so that keep safety.Following explanation is about confirming according to the acceleration condition signal that receives.But should be known in that similar plan can be used for carrying out this according to speed, displacement, peak value, aviation value and/or RMS status signal and confirm.In one embodiment, master controller 500 is confirmed three protection zones basically.Upper area corresponding to than the programming top boundary value a MaxBigger accekeration.Bottom section is corresponding to boundary value a bottom programming MinLittler accekeration.Zone line is corresponding to dropping on top boundary value a MaxWith bottom boundary value a MinBetween accekeration.When acceleration condition signal indication acceleration/accel was in upper area, master controller 500 confirmed to take the protection action, and advanced to piece 642 so that take this action.On the contrary, when acceleration condition signal indication acceleration/accel was in bottom section, master controller 500 was confirmed not take the protection action, and advances to piece 634 so that determine whether to take the protection action according to the state of temperature signal.
For the acceleration/accel in the protection zone in the middle of dropping on, master controller 500 excites the protection action with delayed mode, and postpones to be defined as:
t＝k t·e -α·kc
Wherein, α representes instantaneous acceleration, k tAnd k cIt is pre-determined factor.In one embodiment, top boundary, bottom boundary and coefficient are defined as a Max=500m/s 2a Min=250m/s 2k t=1000; And k c=1/32.Through responding for the acceleration lag that drops in the zone line; Master controller 500 makes bulk material handle the short period section that annex 6 can have the acceleration/accel in zone line, but when the acceleration/accel that is higher than the bottom boundary keeps necessarily extending the time period, excites the protection action.
Except top three protection zones, technical personnel can also use user interface 8 to confirm the relevant boundary of difference with acceleration/accel, speed and displacement between the alternate arm 212 of being with cleaner 80.When master controller 500 confirmed that the movement differential amount of alternate arm 212 surpasses the boundary that is provided with by technical personnel, master controller 500 can be confirmed to advance to piece 642 so that take the protection action.The reason that arm 212 possibly carry out different motion is that cleaner mechanism 86 possibly not have suitable installation, therefore make arm 212 not with conveyor belt 82 proper alignment.Another reason is to be with 82 possibility partial failures, causes a subcontrol 305 to bear obviously higher impact.No matter reason how, the big movement differential between arm 212 is represented the potential dangerous operation with cleaner 80, therefore impels master controller 500 to take action.
When motion can be accepted, master controller 500 can receive the state of temperature signal from subcontrol 305 in piece 634, and can in piece 636, confirm whether can be accepted by the temperature of the status signal report that receives.In one embodiment, when leaving particular range by the temperature of subcontrol 305 reports, master controller 500 confirms to advance to piece 642 so that take the protection action.In one embodiment, technical personnel can use user interface 8 according to material, rule and other environmental conditions of conveyor belt material, transmission temperature limitation to be set.For example, in potential explosion environment, temperature limitation can be decided by the comb. of this particular surroundings.
In piece 638, master controller 500 can be from the main status signal that receives piece 520 and the local power supply 550 about the power supply capacity of each unit of supplying with.Master controller 500 can determine whether to take the protection action according to the power state signal that receives in piece 640.In one embodiment, master controller 500 advances to piece 642, can not fully work or main the supply taked the protection action when piece 520 fluctuates outside some safe limit with any local power supply 550 of box lunch.
In piece 642, master controller 500 is taked the protection action.In one embodiment, master controller 500 produces control signals, and this control signal makes detent mechanism 530 that cleaner mechanism 86 and whole arms 212 are left to be with 82 to return.And master controller 500 also sends the information about protection action of taking and the reason of taking action through user interface 8 to technical personnel.
Except above-mentioned safety method, in one embodiment, conveyor belt cleaner 80 comprises other protection characteristic.Particularly, in one embodiment, the damper 304 of band cleaner arm 212 is biased into minimum damping value C in advance 1Therefore, when bulk material processing controller 12 lost efficacy, damping was converted to lower safety value automatically, and kept like this recovering whole mode of operation up to the maintenance personnel.And bias voltage is protected damper 304 in advance, because this device possibly damage owing to when damper winding is not supplied power, receiving bigger swing.
Action monitoring & performance data stores (AM&FDS)
In one embodiment, master controller 500 each subcontrol 305 of inquiry are so that obtain motion, temperature and other status data from subcontrol 305.In one embodiment, master controller 500 is regularly to subcontrol 305 these data of inquiry.In another embodiment, replace each subcontrol 305 of inquiry, subcontrol 305 regularly sends the status information of collecting to master controller 500.No matter how master controller 500 obtains data from subcontrol 305, in one embodiment, master controller 500 keeps activation record, and this activation record comprises the operating value of each arm 212, the time mark of this value and the relevant parameter that is used to operate this arm 212.Relevant parameter comprises above-mentioned measurement and derivation value and other value, for example is used for the range of safety operation of each security feature.
Master controller 500 can be with all these information storage in memory device 542, and makes these data to be obtained by local or user at a distance through user interface 8.When local storage 542 had been expired, master controller 500 can roughly be removed older data, so that the space that is formed for Updating Information.But, because law and security reason think that prior particular data (user instruction that for example receives through user interface 8) can keep more over a long time.
As previously mentioned, in one embodiment, each subcontrol 305 has can be through calculating the ability of measuring or estimating following instantaneous value: acceleration/accel, speed, displacement, pitch of boom (inclination) and temperature.And each subcontrol 305 can calculate following value for the sample of respectively measuring of acceleration/accel, speed and displacement: aviation value, peak value, mean effective value.These values can be used for the monitoring system action by master controller 500, and parts are regulated.
For example, master controller 500 can be confirmed the mode of operation of each arm 212 according to pitch of boom.Particularly, master controller 500 can be inquired each subcontrol 305 on the basis of rule.Therefore, master controller 500 can keep the pitch of boom data logging of each arm 212.Master controller 500 can keep this record, and like this, the first arm degree of dip of each arm 212 input is corresponding to when mounted pitch of boom reference value.Then, master controller 500 can use the measurement of pitch of boom data with 82 wearing and tearing, because when being with 82 wearing and tearing, the angle of arm 212 or degree of dip change.
Master controller 500 can also be monitored the component of the measurement of bringing onto load and/or transmission according to the status signal that receives from subcontrol 305.Particularly, master controller 500 can be monitored the displacement of each arm 212, and confirms the load with 82 according to the variation of this displacement.Shown in Figure 67, the offset table of arm 212 is shown in the load on 82.Shown in Figure 67, initial displacement is represented empty conveyor belt near zero.After a while, added value has been represented in displacement, and this added value is represented each loading level.And master controller 500 can utilize the technology of monitoring arm 212 displacements to represent that band stops up.
Various characteristic of the present invention has combined example embodiment of the present invention to carry out special expression and explanation, but must know, these special constructions are example description, and the present invention will be to the explanation of its fullest.
