Embodiment 1
The magnetic signal of the magnetic signal of rope-grippers 300 part and wire rope 301 injury region cannot be distinguished to improve in prior art, the safety detection of monkey car wire rope 301 is caused to the problem of adverse effect, the embodiment of the invention discloses the recognition methods of a kind of wire rope 301 rope-grippers 300, mainly for stepless around the monkey car wire rope 301 run, by gathering the Magnetic Field of position on monkey car wire rope 301, and the information collected is carried out graphic software platform, according to wire rope 301 rope-grippers 300 characteristic connected, set rope-grippers 300 condition for identification dexterously, according to the Magnetic Field of graphic software platform, identify rope-grippers 300 accurately, effectively wire rope 301 rope-grippers 300 information and wire rope 301 damage information are made a distinction, make the detection of monkey car wire rope 301 damage information more accurately and reliably.
As shown in Figure 1, method in the embodiment of the present invention is mainly used in wire rope 301 rope-grippers 300 recognition system, wire rope 301 rope-grippers 300 recognition system comprises recognition device and multiple Magnetic Field harvester, Magnetic Field harvester is for gathering the Magnetic Field of wire rope 301 position, and the method comprises:
Step S100: recognition device receives the Magnetic Field of wire rope 301 position that each Magnetic Field harvester collects, obtains the corresponding relation of each position on Magnetic Field and wire rope 301.
Wherein, Magnetic Field harvester can be weak magnetic sensor, Hall element or giant magneto-resistance sensor etc., as long as can extract field signal, Magnetic Field is magnetic energy gesture distributional difference information.According to actual conditions, optionally can detect by one or more sensors above-mentioned, detect demand with the Magnetic Field met under different condition.
All can gather the Magnetic Field of wire rope 301 position to make each Magnetic Field harvester, and do not affect rope-grippers 300 and pass through, the mounting means of wherein a kind of Magnetic Field harvester is provided in the embodiment of the present invention, as shown in Figure 3, as: set up magnetic field charger and multiple pick-up unit 303, multiple pick-up unit 303 is fixed on charger, pick-up unit 303 is set to inverted U, multiple Magnetic Field harvester is evenly distributed in pick-up unit 303, the inverted U opening of multiple pick-up unit 303 is placed in wire rope 301 both sides, make the holding block 302 (with wire rope 301 junction) of rope-grippers 300 by this inverted U opening, because wire rope 301 is that stepless is around operation, rope-grippers 300 is fixed on wire rope 301, together run with wire rope 301, pick-up unit 303 position is fixed, thus, after start detection, pick-up unit 303 maintains static, wire rope 301 always in pick-up unit 303 around operation, each Magnetic Field harvester all can gather the Magnetic Field of wire rope 301 position.Wherein, magnetic field charger can be permanent magnet etc. for carrying out the equipment of weak magnetic planning to wire rope 301, pick-up unit 303 is for installing Magnetic Field harvester additional, after above-mentioned setting, open charger, carry out weak magnetic planning to wire rope 301, wire rope 301 stepless is around operation, and each Magnetic Field harvester all gathers the Magnetic Field of wire rope 301 position.Travel at the uniform speed because wire rope 301 is generally, the acquisition interval of Magnetic Field harvester can sets itself, thus the corresponding relation of each position on Magnetic Field and wire rope 301 can be drawn, such as: setting Magnetic Field harvester collection per second 1000 times, and the speed that wire rope 301 passes through from pick-up unit 303 is 1 meter per second, 1 collection of so corresponding Magnetic Field harvester is exactly 1mm, in like manner, can draw the corresponding relation of Magnetic Field and wire rope 301 each position collected.
Step S101: the oscillogram Magnetic Field that each Magnetic Field harvester collects being shown as respectively corresponding each Magnetic Field harvester.
Wherein, each Magnetic Field harvester all can gather the Magnetic Field of wire rope 301 position, for the ease of intuitively showing and statistics, the Magnetic Field of wire rope 301 position preferably collected by each Magnetic Field harvester in the embodiment of the present invention is shown as oscillogram, so that subsequent analysis and process.
Step S102: crest and the trough of inquiring about each oscillogram respectively, chooses Valid peak and the trough of each oscillogram respectively according to preset range value.
The Magnetic Field collected due to step S100 comprises the damage information of wire rope 301, interfere information, the Magnetic Field etc. at rope-grippers 300 place, thus, in corresponding oscillogram, also correspondence shows the damage information of wire rope 301, interfere information, the Magnetic Field etc. at rope-grippers 300 place, based on this, need filter oscillogram, filtering wire rope 301 damage information, interfere information etc., reservation rope-grippers 300 information, according to the characteristic of wire rope 301 rope-grippers 300 in the embodiment of the present invention, effective information is selected preferably by preset range value, inventor finds after deliberation, this preset range value preferably adopts peak valley drop value, this difference can be and arranges manually, also can automatically generate, can arrange flexibly according to actual conditions, embodiments provide wherein a kind of implementation, comprise:
From the oscillogram that each Magnetic Field harvester is corresponding, choose the preset range value of oscillogram respectively, preset range value is the value range centered by the drop value of oscillogram medium wave peak corresponding to the Magnetic Field at wire rope 301 rope-grippers 300 place that each Magnetic Field harvester collects, trough; Preset range value corresponding with each oscillogram with the drop parameter value of trough for crest adjacent between two in each oscillogram is compared, drop parameter value is belonged to Valid peak and trough that the crest of preset range value and trough are chosen for each oscillogram.
Wherein, because pick-up unit 303 is inverted U structure, install each Magnetic Field harvester within it additional apart from rope-grippers 300 apart from difference, thus, the preset range value adopted between the oscillogram that different magnetic field information collecting device is corresponding generally can there is some difference.
Ideally, after the magnetic signal that wire rope 301 rope-grippers 300 place produces is shown as oscillogram, corresponding peak valley difference is preset parameter value, during filtration, equals the peak valley of this preset parameter value as Valid peak, trough using the peak valley difference found in real time.But this is the preset parameter value under ideal conditions.When practical operation detects, due to all kinds of reason, often there is some difference, thus, the field signal preferably adopting rope-grippers 300 to produce when implementing, after being shown as oscillogram, using the certain percentage of the peak valley difference of correspondence as preset range value, this number percent can be 50% ~ 150%, namely using 0.5 times of preset parameter value to 1.5 times preset parameter value as preset range, the drop parameter value of crest adjacent between two in each oscillogram and trough and this preset range value are compared, drop parameter value is belonged to Valid peak and trough that the crest of this preset range value and trough are chosen for each oscillogram.
Separately, can also the single number percent (being less than 100%) of preset parameter value as " reality " preset parameter value, the drop parameter value of crest adjacent between two in each oscillogram and trough and this preset parameter value are compared, drop parameter value is greater than Valid peak and trough that the crest of this " reality " preset parameter value and trough are chosen for each oscillogram.As: using 80% of preset parameter value, 82%, 85% etc. as " reality " preset parameter value, according to actual conditions, this number percent can flexible, as long as can distinguish rope-grippers 300 information, damage information, interfere information.Such as: rope-grippers 300 value is 100, according to rope-grippers 300 characteristic, so rope-grippers 300 generally has the value of 1 ~ 3 continuous print about 100, and damage information is generally maximum 50, even if having also is single more than 100, it not continuous print, and the value of interfere information is just less, such as 20, so, with the number percent of actual peak valley drop value corresponding to rope-grippers 300 place, as actual value 100 80% as preset range value, namely 80, so just can filter out the Valid peak of rope-grippers 300 part, trough, filtering damage information, the crest that interfere information etc. produce, trough.
Magnetic Field due to wire rope 301 rope-grippers 300 place is generally all greater than the Magnetic Field of wire rope 301 injury region, more much larger than interfere information, thus, by choosing preset range value, and filtered by preset range value, reliably can select the Magnetic Field at wire rope 301 rope-grippers 300 place, Magnetic Field, the interfere information of filtering wire rope 301 injury region, effectively guarantee the accuracy that rope-grippers 300 detects.
Step S103: judge in each oscillogram, Valid peak adjacent between two or trough is whether had to meet decision condition, decision condition is 3 times that distance between Valid peak adjacent between two or trough is less than rope-grippers 300 holding block 302 length, if have, be rope-grippers 300 by wire rope 301 position mark corresponding to Magnetic Field corresponding to the crest or trough that meet decision condition;
Preferably after judging that the distance between Valid peak adjacent between two or trough is less than 3 times of rope-grippers 300 holding block 302 length, judge whether that 1 or 2 ~ 3 continuous print Valid peaks or the trough distance met between Valid peak adjacent between two or trough are less than the condition of 3 times of rope-grippers 300 holding block 302 length, if have, be then labeled as and identify rope-grippers 300.
In above-mentioned steps, following rule is followed in selecting of crest, trough: judge whether in the same way the magnetic field loading direction of magnetic field charger and the detection side of Magnetic Field harvester to, in the same way, adopts Valid peak; Anti-phase, adopt effective trough.
Step S104: when for each oscillogram, and when the same position of wire rope 301 is all labeled as rope-grippers 300 by Magnetic Field harvester over half, marker for determination is the same position of the wire rope 301 of rope-grippers 300 is rope-grippers 300.
In above-mentioned, judge whether that 1 or 2 ~ 3 continuous print Valid peaks or the trough distance met between Valid peak adjacent between two or trough are less than the rule of the same follow procedures S103 of the condition of 3 times of rope-grippers 300 holding block 302 length: judge whether in the same way the magnetic field loading direction of magnetic field charger and the detection side of Magnetic Field harvester to, in the same way, Valid peak spacing is adopted; Oppositely, effective trough spacing is adopted.
Wherein, although each Magnetic Field harvester all can detect the Magnetic Field of wire rope 301 position, namely, each Magnetic Field harvester all can detect the Magnetic Field at rope-grippers 300 place, perfect condition, when needing all Magnetic Field harvesters all the same position of wire rope 301 to be labeled as rope-grippers 300, can marker for determination be the same position of the wire rope 301 of rope-grippers 300 be rope-grippers 300, but, each Magnetic Field harvester distance rope-grippers 300 is apart from different (pick-up unit 303 is inverted U), when practical application, owing to can shake when rope-grippers 300 runs, displacement etc., the peak valley difference of the oscillogram that the Magnetic Field that distance rope-grippers 300 is collected apart from Magnetic Field harvester relatively far away is corresponding may depart from preset range value, the Magnetic Field harvester of also not all can be distinguished and detect rope-grippers 300 (meeting condition for identification), thus, the embodiment of the present invention considers actual conditions, rope-grippers 300 can be defined as when only needing Magnetic Field harvester over half to be rope-grippers 300 by this position mark, more can guarantee the integrality that rope-grippers 300 detects.
By above-mentioned steps, accurately can identify wire rope 301 rope-grippers 300 information, wire rope 301 rope-grippers 300 information not obscured with wire rope 301 damage information, is convenient to the detection of wire rope 301 damage information.

As shown in Figure 2, wire rope 301 rope-grippers 300 recognition device in the embodiment of the present invention is applied to wire rope 301 rope-grippers 300 recognition system, wire rope 301 rope-grippers 300 recognition system comprises this recognition device and multiple Magnetic Field harvester, Magnetic Field harvester is for gathering the Magnetic Field of wire rope 301 position, recognition device comprises: receiving element 200, for receiving the Magnetic Field of described wire rope 301 position that each described Magnetic Field harvester collects, obtain the corresponding relation of described Magnetic Field and described wire rope 301 each position, pattern displaying unit 201: the described Magnetic Field that each described Magnetic Field harvester for being received by described receiving element 200 collects is shown as the oscillogram of corresponding each described Magnetic Field harvester respectively, choose unit 202: for inquiring about crest and the trough of each described oscillogram respectively, crest and the trough that peak valley drop value adjacent between two belongs to described preset range value is chosen respectively, using the described crest chosen and trough as Valid peak and trough according to preset range value, judging unit 203: for respectively for each described oscillogram, judge in each described oscillogram, described Valid peak adjacent between two or trough is whether had to meet decision condition, described decision condition is 3 times that distance between described Valid peak adjacent between two or trough is less than described rope-grippers 300 holding block 302 length, if have, be rope-grippers 300 by described wire rope 301 position mark corresponding to Magnetic Field corresponding to the crest or trough that meet described decision condition, identifying unit 204: for working as each described oscillogram, and described Magnetic Field harvester over half is when being all labeled as rope-grippers 300 by the same position of described wire rope 301, be labeled as the same position of the wire rope 301 of rope-grippers 300 described in judging as rope-grippers 300.
By said apparatus, accurately can identify wire rope 301 rope-grippers 300 information, wire rope 301 rope-grippers 300 information not obscured with wire rope 301 damage information, is convenient to detection and the identification of wire rope 301 damage information.
Wherein, although each Magnetic Field harvester all can detect the Magnetic Field of wire rope 301 position, namely, each Magnetic Field harvester all can detect the Magnetic Field at rope-grippers 300 place, but, each Magnetic Field harvester distance rope-grippers 300 is apart from difference, the Magnetic Field harvester of also not all can be distinguished and detect rope-grippers 300 (meeting condition for identification), thus, rope-grippers 300 can be defined as when only needing Magnetic Field harvester over half to be rope-grippers 300 by this position mark, more can guarantee the integrality of the accuracy that rope-grippers 300 detects and damage information identification.
Wherein, Magnetic Field harvester can be weak magnetic sensor, Hall element or giant magneto-resistance sensor etc., as long as can extract field signal, Magnetic Field is magnetic energy gesture distributional difference information.According to actual conditions, optionally can detect by one or more sensors above-mentioned, detect demand with the Magnetic Field met under different condition.
Wherein, choose unit 202 specifically for from oscillogram corresponding to each Magnetic Field harvester, choose respectively oscillogram medium wave peak corresponding to the Magnetic Field at wire rope 301 rope-grippers 300 place that each Magnetic Field harvester collects, trough drop value (being multiplied by certain percentage) as the preset range value of oscillogram corresponding to each Magnetic Field harvester; Preset range value corresponding with each oscillogram with the drop parameter value of trough for crest adjacent between two in each oscillogram is compared, drop parameter value is belonged to Valid peak and trough that the crest of preset range value and trough are chosen for each oscillogram.
The Magnetic Field received due to receiving element 200 comprises the damage information of wire rope 301, interfere information, the Magnetic Field etc. at rope-grippers 300 place, thus, in corresponding oscillogram, also correspondence shows the damage information of wire rope 301, interfere information, the Magnetic Field etc. at rope-grippers 300 place, based on this, need filter oscillogram, filtering wire rope 301 damage information, interfere information etc., reservation rope-grippers 300 information, according to the characteristic of wire rope 301 rope-grippers 300 in the embodiment of the present invention, effective information is selected preferably by preset range value, inventor finds after deliberation, this preset range value preferably adopts peak valley drop value, this difference can be and arranges manually, also can automatically generate, can arrange flexibly according to actual conditions, embodiments provide wherein a kind of implementation, be specially:
Choose unit 202 for from oscillogram corresponding to each Magnetic Field harvester, choose the preset range value of oscillogram respectively, preset range value is the value range centered by the drop value of oscillogram medium wave peak corresponding to the Magnetic Field at wire rope 301 rope-grippers 300 place that each Magnetic Field harvester collects, trough; Preset range value corresponding with each oscillogram with the drop parameter value of trough for crest adjacent between two in each oscillogram is compared, drop parameter value is belonged to Valid peak and trough that the crest of preset range value and trough are chosen for each oscillogram.
Wherein, because pick-up unit 303 is inverted U structure, install each Magnetic Field harvester within it additional apart from rope-grippers 300 apart from difference, thus, the preset range value adopted between the oscillogram that different magnetic field information collecting device is corresponding generally can there is some difference.
Ideally, after the magnetic signal that wire rope 301 rope-grippers 300 place produces is shown as oscillogram, corresponding peak valley difference is preset parameter value, during filtration, equals the peak valley of this preset parameter value as Valid peak, trough using the peak valley difference found in real time.But this is the preset parameter value under ideal conditions.When practical operation detects, due to all kinds of reason, often there is some difference, thus, the field signal preferably adopting rope-grippers 300 to produce when implementing, after being shown as oscillogram, using the certain percentage of the peak valley difference of correspondence as preset range value, this number percent can be 50% ~ 150%, namely using 0.5 times of preset parameter value to 1.5 times preset parameter value as preset range, the drop parameter value of crest adjacent between two in each oscillogram and trough and this preset range value are compared, drop parameter value is belonged to Valid peak and trough that the crest of this preset range value and trough are chosen for each oscillogram.
Separately, can also the single number percent (being less than 100%) of preset parameter value as " reality " preset parameter value, the drop parameter value of crest adjacent between two in each oscillogram and trough and this preset parameter value are compared, drop parameter value is greater than Valid peak and trough that the crest of this " reality " preset parameter value and trough are chosen for each oscillogram.As: using 80% of preset parameter value, 82%, 85% etc. as " reality " preset parameter value, according to actual conditions, this number percent can flexible, as long as can distinguish rope-grippers 300 information, damage information, interfere information.Such as: rope-grippers 300 value is 100, according to rope-grippers 300 characteristic, so rope-grippers 300 generally has the value of 1 ~ 3 continuous print about 100, and damage information is generally maximum 50, even if having also is single more than 100, it not continuous print, and the value of interfere information is just less, such as 20, so, with the number percent of actual peak valley drop value corresponding to rope-grippers 300 place, as actual value 100 80% as preset range value, namely 80, so just can filter out the Valid peak of rope-grippers 300 part, trough, filtering damage information, the crest that interfere information etc. produce, trough.
Magnetic Field due to wire rope 301 rope-grippers 300 place is generally all greater than the Magnetic Field of wire rope 301 injury region, more much larger than interfere information, thus, by choosing preset range value, and filtered by preset range value, reliably can select the Magnetic Field at wire rope 301 rope-grippers 300 place, Magnetic Field, the interfere information of filtering wire rope 301 injury region, effectively guarantee the accuracy that rope-grippers 300 detects.
