Embodiment
A kind of elevator based on experts database technology is led from dynamic rail method for aligning, is comprised the following steps：
Step 1：Successful empirical data is manually aligned using early stage, place is normalized to span and pressure point bending value
Reason, determines span, pressure point bending value and corresponding volume under pressure, constitutes experts database；What stride values were normalized is specific
Method is：Span is more than the unified of 1000mm and sets span as 1000mm, the span between 800mm to 1000mm is normalized to
The span that span between 800mm, 600mm to 800mm is normalized between 600mm, 0mm to 600mm is normalized to 400mm.
It is to the specific method that pressure point bending value is normalized：It will be greater than in the case of 1000mm spans and 800mm spans
Bending value equal to 2mm is uniformly normalized to 2mm, will be greater than uniformly being normalized to equal to the bending value that 1.5mm is less than 2mm
1.5mm, is uniformly normalized to 1.3mm more than or equal to the 1.3mm bending values for being less than 1.5mm, is less than 1.3mm's more than or equal to 1mm
Bending value is uniformly normalized to 1mm, 0.8mm is uniformly normalized to more than or equal to the 0.8mm bending values for being less than 1mm, less than 0.8mm
Bending value be uniformly normalized to 0.5mm；The bending value equal to 1mm is will be greater than in the case of 600mm spans and 400mm spans
1mm is uniformly normalized to, will be greater than uniformly being normalized to 0.8mm equal to the bending value that 0.8mm is less than 1mm, more than or equal to 0.6mm
Bending value less than 0.8mm is uniformly normalized to 0.6mm, and the bending value more than or equal to 0.4 less than 0.6mm is uniformly normalized to
0.4mm, is uniformly normalized to 0.3mm, the bending value less than 0.3mm is uniformly returned more than or equal to the 0.3mm bending values for being less than 0.4mm
One turns to 0.2mm.
Step 2：The linearity information of guide rail is gathered, is write music line according to gathered data fitting a straight line, fitting a straight line is write music line
Specific method be：
Step 2.1：The guide rail linearity information of laser range finder detection, i.e. laser range finder is gathered every 10 milliseconds to sense
Device is the distance between to guide rail；
Step 2.2：Draw before linearity curve, the transverse and longitudinal coordinate ratio of last point is calculated, according to this ratio pair
All points are moved up or moved down accordingly adjustment；First is collected a little as origin,
Step 2.3：Using first point as origin, the data after adjustment are fitted, and draw curve.
Step 3：Data analysis is carried out to the curve of fitting using traversal Extremal point algorithm, pressure point reference point is chosen, chooses pressure
Point reference point specific method be：
Step 3.1：Since the 21st point of curve, compare the ordinate size of current point and front and rear each 20 points, if than
The ordinate absolute value of 20 points of the right and left is all big, then judge the point can as pressure point reference point, otherwise cannot function as
The reference point of pressure point；
Step 3.2：According to the method for step 2.1, traversal removes the institute of first 20 and latter 20 a little, from whole piece guide rail straight line
Write music in line can as pressure point reference point；
Step 3.3：Remove the point that bending value is less than minimum precision from pressure point reference point.
Step 4：Found out according to the qualified index of guide rail linearity and do not conform to lattice point, joined according to the position of unqualified index from pressure point
Final pressure point is determined in examination point；
Step 4.1：The qualified index of guide rail linearity is set, including whole long bending value, every meter of bending value, left and right 500mm curved
Song value and B/A values；
Step 4.2：Calculate each index actual value, choose the pressure point reference point before and after unqualified index location in 20 points and make
For pressure point：First by one priority of these setup measures, whole long bending value priority is set to curved at highest, left and right 500mm
Bent value is taken second place, and then considers B/A values, and every meter of qualified index is last, and the high first aligning of priority makes it meet requirement；If whole length is curved
Song value is unqualified, then pressure point reference point is aligned as pressure point；If whole length is qualified, left and right 500mm is unqualified, then does not consider
The position of pressure point reference point, directly using or so 500mm be used as pressure point；If whole length is qualified, left and right 500mm is qualified, and B/A is unqualified,
The position for then B/A not being conformed to lattice point is used as pressure point；If whole length, left and right 500mm, B/A values are qualified, every meter unqualified, then every meter
The position of lattice point is not conformed to as pressure point, the absolute value of its corresponding ordinate value of the pressure point chosen is the bending value of the point.
Step 5：Readjust and determine after pressure point, it is symmetrical really on pressure point both sides further according to the maximized principle of span
Determine position of the fulcrum, the selection principle of fulcrum is：Fulcrum is symmetrically distributed in pressure point both sides, and the span of adjacent fulcra can not influence
To other pressure points, and the whole long scope of guide rail can not be exceeded, it is tried one's best greatly in the case where meeting condition.
Step 6：Experts database data are matched for convenience, are determined after pressure point and fulcrum, to the bending value and span of pressure point
It is normalized, corresponding volume under pressure is matched in experts database according to the bending value and span of the pressure point after normalization,
Guide rail is aligned as the displacement of briquetting motor with the volume under pressure, is to the method for normalizing of span：Span is big
Unified in 1000mm sets span as 1000mm, and the span between 800mm to 1000mm is normalized to 800mm, and 600mm is arrived
The span that span between 800mm is normalized between 600mm, 0mm to 600mm is normalized to 400mm.Thus obtain,
The span of pressure point.It is to the specific method that pressure point bending value is normalized：In 1000mm spans and the feelings of 800mm spans
The bending value equal to 2mm is will be greater than under condition and is uniformly normalized to 2mm, will be greater than uniformly returning equal to the bending value that 1.5mm is less than 2mm
One turns to 1.5mm, is uniformly normalized to 1.3mm more than or equal to the 1.3mm bending values for being less than 1.5mm, is less than more than or equal to 1mm
1.3mm bending value is uniformly normalized to 1mm, and 0.8mm is uniformly normalized to more than or equal to the 0.8mm bending values for being less than 1mm, small
0.5mm is uniformly normalized in 0.8mm bending value；It will be greater than being equal to 1mm in the case of 600mm spans and 400mm spans
Bending value be uniformly normalized to 1mm, will be greater than be equal to 0.8mm be less than 1mm bending value be uniformly normalized to 0.8mm, be more than
0.6mm is uniformly normalized to equal to the 0.6mm bending values for being less than 0.8mm, the bending value more than or equal to 0.4 less than 0.6mm is unified
0.4mm is normalized to, 0.3mm is uniformly normalized to more than or equal to the 0.3mm bending values for being less than 0.4mm, the bending less than 0.3mm
Primary system one is normalized to 0.2mm.
Step 7：Linearity surveying is carried out to guide rail again, required if the indices of guide rail are met, by each of guide rail
Achievement data is saved in database, if guide rail index is unqualified, return to step 3 is aligned next time.
The inventive method can accurate straightening rail, substantially increase the security and comfortableness of lift car operation.
Below in conjunction with the accompanying drawings the present invention program is elaborated with specific embodiment.
Before method for aligning is implemented, putting up first should be by platform, by the data transmit-receive signal of laser range sensor
Line is connected with the serial ports of the RS on PC -232, and motion control board and each motor servo driver and PLC are connected
Connect, determine that hardware platform smooth can be run.The logic flow of experts database guide rail aligning algorithm is as shown in Fig. 2 specific real
Apply step as follows：
Step 1：Successful empirical data is manually aligned using early stage, place is normalized to span and pressure point bending value
Reason, determines span, pressure point bending value and corresponding volume under pressure, constitutes experts database；
Step 2：With serial port communication technology, every 10 milliseconds of sensors for measuring laser range sensor to guide rail it
Between distance pass PC back, be stored in array, and the point that first is collected connects as origin in rectangular coordinate system
Point retouches line.The track and the guide rail line that is linked to be of ending that are translated due to sensor is simultaneously not parallel, so last point of guide rail does not exist
, it is necessary to which according to the transverse and longitudinal coordinate ratio of last point, the point retouched above line all is carried out into phase by this ratio above reference axis
That answers moves up or moves down adjustment.Then new data is fitted and handles and draw curve, and the value that each is put by new curve
It is saved in array, it is convenient followed by data analysis.Final curves are as shown in figure 3, the curve is contained from guide rail head altogether
To 500 data points at guide rail end, curvilinear abscissa shows rail bends value situation, the more remote bending of ordinate absolute value
Value is bigger.
Step 3：As seen from Figure 3, it is characterized in that ordinate is a range of more than both sides as pressure point bending point
Point, carries out data analysis to the curve of fitting using the method for traversal extreme point, chooses pressure point reference point.Due to hardware platform limit
System, is 20cm as the distance between briquetting of pressure point, so the 21st point is traveled through above curve, compares the point with before
The ordinate size of each 20 points, if all bigger than the ordinate absolute value of other points in 20 point ranges of the right and left, sentences afterwards
Break the point can as pressure point reference point, otherwise not as guide rail align reference point.The point time from 20th o'clock to the 480th
Going through one time just can determine all aligning reference points of the guide rail.Bending value, which is selected, in these aligning reference points is less than minimum essence
The point of degree removes, and other ungratified points are saved in array, is referred to as aligning.Only one of which pressure point reference point in Fig. 3.
Step 4：Guide rail aligning is to remove aligning according to certain accuracy standard index, is not that finally guide rail is aligned
For a smooth straight line, therefore it is determined that when final pressure point, not only to consider the whole piece guide rail traveled through out in step 3
On bending point, i.e. pressure point reference point, it is also contemplated that removing aligning for guide rail criterion of acceptability, can so greatly improve guide rail
Align efficiency.The qualified index of guide rail mainly has whole long bending value, every meter of bending value, left and right 500mm bending values and B/A values.
Whole long bending value, intuitively reflects the bending situation of guide rail, is defined as on straightness error curve ordinate most
Big value y1With minimum value y2Difference.
B/A values, reflection is the limitation to curve peak position, is defined as movement curve ordinate absolute value most
The absolute value of the ordinate of big point and the abscissa of the point are to the ratio of the nearer distance in two ends, and B/A value is：
In formula, y1It is the ordinate value of the point of ordinate maximum absolute value in curve, x1It is the corresponding abscissa value of point.
Bending value at the 500mm of left and right, as the term suggests the bending value on guide rail at 500mm and 4500mm, reflection is to work as
After many guide rails are by cloudy tenon and positive feather joint, the planarization of integrated guide rail, when calculating, with the absolute of 2 points of the ordinate
Value is used as record.
Every meter of maximum deflection value, reflection is whole long bending value of the guide rail in the range of one meter, is to ensure that whole guide rail is
At most the important indicator of the flatness of root guide rail connection, is defined as, each rice in the range of guide rail linearity error progressive with 100mm
Each whole long bending value in maximum, that is, at [0mm, 1000mm], [100mm, 1100mm] ... [3900mm,
4900mm], the corresponding whole long bending of the maximum area segments of whole long bending value in [4000mm, 5000mm] this 41 sections of one meter of regions
Value.
By four kinds of computational methods above, each index actual value is calculated, index nonconformance is found out, generally whole length
The pressure point tackled when unqualified is corresponding with bending point, when in left and right, 500mm is unqualified, and generally the point is not time
The pressure point gone through out.Therefore pressure point is adjusted, it is some or all of to give up the pressure point traveled through out, again according to unqualified feelings
Condition is to pressure point.Specific adjustable strategies：First, by one priority of these setup measures, the high first aligning of priority meets it
It is required that.Here whole long bending value priority is set into bending value at highest, left and right 500mm to take second place, remaining two indices are last.
Because a large amount of scene aligning data displays：It is general after whole long bending value and left and right 500mm place bending value are all qualified, remaining finger
The mark overwhelming majority can meet requirement, if it is not satisfied, being aligned again individually for it.Then, if only whole long bending value is unqualified,
The branch pressure point information then calculated according to original algorithm is aligned；If there is other indexs unqualified, and former algorithm is in influence
Pressure point is not calculated near the index, then increases a pressure point specifically designed for the index.Finally, if whole long bending value is to meet
It is required that, then pressure point is adjusted to first mainly for the index at the 500mm of left and right, finally solves B/A values and every meter of maximum deflection
Value.Adjustable strategies flow is as shown in Figure 4.
Step 5：Readjust and determine after pressure point, it is symmetrical really on pressure point both sides further according to the maximized principle of span
Determine position of the fulcrum.It is determined that during position of the fulcrum, first having to consider that the span on the left side pressure point left side can not be than Far Left pressure point to song
The lateral separation of line starting point is long, and the span on the right of the pressure point of the right can not be longer than the lateral separation of rightmost pressure point to End of Curve.
Secondly consider that the abscissa of left side fulcrum can not be bigger than the abscissa of the right fulcrum.Under the conditions of the two are met, as far as possible greatly
Selection stride values.Experts database data are matched for convenience, and the stride values calculated are normalized, span is more than
The unified of 1000mm sets span as 1000mm, and the span between 800mm to 1000mm is normalized to 800mm.The like, one
No longer reduce span when the minimum value 400mm of stride values, be uniformly normalized to 400mm.Thus obtain, pressure point it is curved
Song value and span.
Step 6：When determining volume under pressure according to the bending value and span of pressure point, due to contains only major part in experts database just
True volume under pressure, not comprising whole volumes under pressure under whole spans, therefore also needs to enter the bending value that bending value is similar
Row normalized.For example, 2mm bending value is uniformly normalized into 2mm in the case of 1000mm spans, it will be greater than
The bending value that 1.5mm is less than 2mm is uniformly normalized to 1.5mm, the like, place is also normalized in each bending value
Reason, so as to realize the standardization of experts database matching, improves the efficiency of guide rail aligning.Mechanical part is provided down according to experts database
Pressure amount is aligned to the bending point of guide rail.
Step 7：After guide rail aligning terminates, then Linearity surveying is carried out to guide rail, because experts database is to employ a large amount of realities
Obtained accurate data is tested, success can be aligned as Fig. 5 according to the most of guide rail of given volume under pressure, then will be closed
The data of lattice are saved in database.But there is small part guide rail due to material difference, it is impossible to disposably align successfully, need by
The data detected again are sent to data analysis module and analyzed, so as to be aligned, until aligning successfully next time.
