Embodiment
First monitoring arrangement possesses: the mensuration control part of setting the condition determination of determination unit and the start-stop of the determination unit of indication under this condition etc.; Determination data that record is sent here from determination unit and the record/display part that shows at monitor; The collection portion of data is accumulated in preservation; Resolve and preserved the data of collecting and judge the unusual arbitration functions portion that has or not; And when in arbitration functions portion, judging when the unusual generation that surpasses the value set or level is arranged; Communicate by letter with second monitoring arrangement; And corresponding to requirement/indication from second monitoring arrangement; Send the Department of Communication Force of data that record accomplishes etc., second monitoring arrangement has: verify unusual report of sending here from first monitoring arrangement, judge whether to carry out the request of data judging part of the detailed data request of view data, numeric data etc.; The data that parsing is sent here from first monitoring arrangement, the arbitration functions portion that has or not of the necessity that the judgement rope is changed; And with the instruction reception and registration portion of this result to the transmission of first monitoring arrangement.
Preferably distinguishing assay is interval on the longitudinal direction of rope, resolves the increase of the process in time of each time measured value in same interval, whether surpasses certain reference value with this increment rate and judges unusual having or not.
Thus, because be not the inspection that depends on sensation such as experience, but judge the deterioration of rope objectively quantitatively, so the result does not have deviation, can shorten the judgement time in addition, determination data increases more and can feed back to actual achievement more, can improve precision.
In the decision procedure that uses; The state estimating of wirerope is to liking broken string; The voltage height that the evaluation of measured value is caused as the broken string that will measure in the interval is divided into a plurality of levels and gives the value of weight respectively; Check above-mentioned evaluation of estimate over time, when surpassing the rate of change of allowing, be judged as unusual.
Thus, even equal through the degradation of the time point during certain, but because under the fierce situation of the rate of change in this process, be judged as unusual, so can corresponding burst unusual, can highly keep security.
In the decision procedure that uses; The state estimating of cable wire is to liking broken string; Since be benchmark from the integrated value (signal area value) of measuring the broken string magnitude of voltage in the interval, detect the variation of the integrated value of every number of run, when this variations surpasses the rate of change of allowing, be judged to be unusually.
Thus, outside above-mentioned effect, because can easily discern the degree that broken string takes place, so can improve the correctness of judgement.
Followingly embodiments of the invention are described with reference to accompanying drawing.
Fig. 1 and Fig. 2 represent to apply the present invention to deepwater boats and ships, for example are applied to the example of the rope deterioration telemonitoring in the derrick barge; The 1st, be arranged at the crane of boats and ships A; The 2nd, be used for the wirerope of crane 1; The 3rd, be configured in the analyzer on the suitable place of mobile route of wirerope 2, though in this example near masthead portion, be not limited thereto.
The 4th, be configured near the console panel the analyzer 3, be equipped with the wireless LAN device 4b that controller 4a and data transmission are used.The 5th, wireless LAN antenna, 6 is first monitoring arrangements, in the equipment monitoring room B aboard ship.
7 be arranged on remotely, for example be second monitoring arrangement of the C of supervision institute in Japan, antenna is used in 8 transmission that are arranged on the ship, comprises the antenna of for example international maritime satellite (INMARSAT) usefulness that communicates via telstar D.
Said determination device 3 uses the magnetic leakage detection device in this example, as shown in Figure 3, in body, possesses: the magnet 3a of magnetization wirerope; , cable wire (wire) broken string detects the magnetic test coil 3b of magnetic leakage flux when taking place; And the acceleration transducer 3c of the speed when detecting wirerope and in magnetic field, moving.And; In the test section externally; Have based on passing through the detected acceleration of above-mentioned acceleration transducer 3c; To the unit that the electromotive force that detects through magnetic test coil 3b is revised, this amending unit has: based on the correction circuit 30 of acceleration to being revised and exported by the detected signal of magnetic test coil 3b; And modified value is sent to the correction adjustment circuit 31 of above-mentioned correction circuit based on detect acceleration signal by acceleration transducer 3c.Correction adjustment circuit 31 is imported correction circuit 30 as corrected signal no matter the relative acceleration of magnetic test coil 3b and wirerope is calculated the degree that makes detection signal rise or descend so that the detection signal level is certain mode.Have again,, also possess certainly: amplifier, wave filter, wave detector etc. though do not illustrate.
Because wirerope is by constituting as the hard wire (carbon steel) of kicker magnet, thus when the magnet through the magnetization detecting device with wirerope on direction of principal axis during hard magnetization, because long-pending variation the such as the partial cross section of cable wire broken string etc. causes the magnetic leakage flux variation.Variable quantity with this magnetic leakage flux of magnetic test coil 3b inspection notes abnormalities through converting electric signal to.Enumerating concrete specification example is, the diameter of wire cord of application: 40～60mm, finding speed 15～90m/min, the mode of magnetization: the dc magnetization that utilizes permanent magnet.
Usually, sectional area changes more that large-signal also becomes more greatly, and in addition, the size of signal is in measuring speed.But, be not necessarily in magnetic field under the situation of rope fast moving in the translational speed of wirerope, the broken string of cable wire or the disorder that promotes the magnetic field that noise (lift noise) causes become big, detect little cable wire broken string or promote noise.With respect to this, under the slow-footed situation of wirerope, even the state of affairs that big broken string also is not detected takes place.Therefore, as above-mentioned and with acceleration transducer and amending unit, even the velocity variations of wirerope can corresponding its make the detection signal level above-mentioned or descend, can be with the broken string of constant accuracy of detection mensuration cable wire etc.
The controller 4a of above-mentioned console panel 4 is the unit that the detection signal from said determination device 3 output carried out A/D conversion process and record, and the determination data that has been digitized is transferred to monitoring arrangement 6 through WLAN via lan device.
The expert that second monitoring arrangement 7 is positioned at the deterioration/abnormality juding of rope belongs to remotely, and is same with first monitoring arrangement 6, possesses computing machine 7a and the Internet coupling arrangement 7b.
Have again; The determination data of in above-mentioned first monitoring arrangement 6, preserve collecting is resolved and judged the unusual arbitration functions portion that has or not; With the arbitration functions portion that has or not that the unusual detailed data in second monitoring arrangement 7 is resolved and judge the necessity that rope is changed, request of data judging part etc. are constructed as software.
Measuring is that distinguishing assay is interval on the rope longitudinal direction basically, on one side with needed speed rope is moved in this example, Yi Bian continuously magnetic leakage flux voltage is detected.This determination data has preferably carried out the data of speed correcting process through acceleration transducer and amending unit as above-mentioned.
Then, to the computing machine 6a of first monitoring arrangement 6 wireless transmission determination data, preserve determination data from console panel 4.Said determination carries out regularly at each; Every echo is shown and is recorded in the determination data in the same differentiation; Resolving it over time in above-mentioned decision-making function portion, is when having surpassed the value of certain benchmark or increment rate in judgement, and the computing machine 7a of second monitoring arrangement 7 is sent unusual generation.
Fig. 4 has represented the watch circle of system of the present invention for example, prepares as operation, with private cable connection detector 3 and controller 4a, on the other hand detecting device 3 is arranged on the place of regulation, carries out the setting of controller 4 then.This is that the channel of measuring (1ch) is made as ON, selects the finding speed change-over switch.Then, confirm the normal towards whether of wireless LAN antenna, the antenna of monitoring room side is towards the direction of detecting device side antenna 5.In addition, confirm the closing of the circuit of international maritime satellite.
About the computing machine 6a of first monitoring arrangement 6, LAN cable, telephone line cable, feed cable are connected to computing machine, making power supply is ON.Confirm program start, import the IP address of LAN, the address that connects PORT and send mail with communication setting.Carry out in addition mail communication setting (message authentication applies, transceiver at interval, the concluding time).In addition, in measuring setting, set value, the judgement starting position (for example 2m) of rope speed (actual speed), judgement level (for example 2V), in addition, the folder name of input preservation data.
Then, in measuring setting, carry out the setting of Time Triggered (time trigger).Under the situation of once-a-day mensuration (moment certain begins), to choose and measure constantly, the zero hour is measured in input.Under the situation of measuring space, choose at interval the input measuring interval.Import minute (for example, MAX30 minute) at last, click setting key.Thus, begin automatically to measure in the moment of setting.
Under the situation of the setting pattern beyond Time Triggered, select manual triggers or simple measuring (simple measure).Under the situation of manual triggers, when clicking mensuration beginning button, measure beginning.Under the situation of simple measuring, format (format) in preparation of determine, begin to measure in mensuration, finish measuring end.In addition, outside this, also adopt scrambler to trigger (encoder trigger).This is as Fig. 2, to use the rotary encoder be attached to analyzer 3, when on rope, motion being arranged, and the pattern that begins to measure according to output from demoder.The displacement of rope can be write down according to the output of this demoder, locating of rope can be confirmed.
Behind above beamhouse operation, send sign on through WLAN to the controller 4a of detecting device 3 from computing machine 6a, begin to measure.Controller 4a obtains the data of setting-up time, with determined signal carry out A/D conversion and as digital signal record to this body memory, and record the storer of computing machine 6a through WLAN, simultaneously determination data is shown on monitor.In the textbox of computing machine 6a, import the voltage of the speed and the judgement level of determination object rope in advance.The judgement level is the voltage when judging.The monitor picture before the beginning is measured in Fig. 5 (a) expression, and top is the whole chart of determination data, and the bottom is to amplify chart, enlarges to be presented at the position of selecting on the whole chart.An example of Fig. 5 (b) expression determination data high voltage (magnetic leakage flux) occurs five positions.Determination data is based on the data of the detection signal of magnetic test coil being revised by the acceleration of acceleration transducer perception.
The collection portion of computing machine 6a is just preserved/be accumulated in to such data when measuring, in arbitration functions portion, resolve whether surpassed predefined benchmark (setting), carries out unusual judgement.Fig. 6 (a) is the time dependent example of (c) expression determination data waveform (b), (a) the expression voltage waveform 340,000 times time the for example, and (b) the expression voltage waveform 520,000 times time the for example can be known broken string has taken place.Voltage waveform when (c) representing 560,000 times can know that broken string increases.
As the method for judging (evaluation) in the data of arbitration functions portion, can enumerate the method for estimating with voltage height here.This is the maximum magnetic leakage flux voltage that preestablishes through after for many years, when the value that surpasses it takes place, is judged as unusual.For example, will be set at 4V through the maximum magnetic leakage flux voltage for many years, the data after a year are maximum 1.8V, and the data after 2 years are judged as when being maximum 4.9V unusually.
But,, occur under the situation of much such value in certain interval though for example the data after 2 years are the maximum 3.5V that do not reach the setting level; Should be on Security Countermeasures as unusual generation; But it is under said reference, be judged to be normal possibility, and inappropriate.
Therefore, a kind of suitable evaluation method of motion of the present invention.First mode of preferred evaluation method; Be the voltage height of certain level of inspection in the certain measurement interval and the data number (time or length) that surpasses it; For example will be made as 1 above the weight of the situation of 1V, and suppose that 50 points (data number), 0.5 second, 10mm will be long, the data number is that the voltage number also can.
Then, a peek level is also given weight respectively in voltage height.For example, suppose to surpass 1V: weight 1:50 point (data number) surpasses 2V: weight 2:30 point (data number) surpasses 3V: weight 3:15 point surpasses 4V: during weight 4:5 point (data number), and 1 * 50+ (2-1) * 30+ (3-2) * 15+ (4-3) * 5=100.Therefore, high-tension weight is big, is 5 through making weight above 3V for example, the weight that surpasses 4V is 8 etc., influence that can the reflecting voltage height.Under above condition, observe (inclination of variation) over time of evaluation of estimate, judge to changing the unusual of state for the situation more than certain at rate of change.
For example, above-mentioned evaluation of estimate is after being assumed to be 1 year under certain situation: after 10,2 years: after 20,3 years: 30 (Mode As), be 1 year in other cases after: after 5,2 years: after 8,3 years: 30 (Mode Bs)
The maximum rate of change of these situation is 22/ year under Mode B for being 10/ year under Mode A.Therefore,, be judged as that Mode A can use, Mode B will be changed when setting rate of change more than 20/ year during for the replacing level, can corresponding burst or rapid deterioration.
The relation of Fig. 7 (a) expression evaluation of estimate and line strength rate, retained strength rate are 90% to be equivalent to evaluation of estimate 20.(b) relation of express time and evaluation of estimate because Mode B is the angle at angle of inclination of overstepping the extreme limit, will be changed so this wirerope is judged as.
Then; Second mode at the evaluation method of arbitration functions of the present invention portion is; Integrated value (signal area value) with the magnitude of voltage that comes from the interval broken string of the certain mensuration of expression is a benchmark; Detect the variation of the integrated value of every number of run, when the size of this variation surpasses the rate of change of allowing, be judged to be unusual mode.
At length say, the signal voltage value waveform that Fig. 8 representes to break and causes, voltage is 4.4V.The relation of broken string under the situation of Fig. 9 presentation graphs 8 and signal area value.Area is 120 in this example.The signal area value is the integrated value of the length (position) of the waveform represented of magnitude of voltage shown in Figure 8, with the uniform velocity segmentation and obtain under the data conditions, can try to achieve through the discrete integration of Σ (magnitude of voltage * data number).This is to be utilized in the computing function of arbitration functions portion and to try to achieve automatically.Compare with Fig. 8 that waveform is near the normal distribution shape among Fig. 9, the wiring of the position beyond abnormal signal becomes smooth.Therefore, can not discern the generation state of broken string by error.
Have, the speed of the rope in data is not under the situation of uniform velocity again and since the long data number of per unit speed more fast time variant must lack more, so can revise or the weight of summarized information according to speed.For example, be under the situation of twice at velocity contrast, the speed of needing only is that the data and 2 of twice multiply each other, the weight that increases data gets final product.
Figure 10 is illustrated in the voltage of data several 6 and the relation of rope retained strength, and Figure 11 representes the relation of area (voltage * data number) and rope retained strength.R2 means related coefficient.
With the relation of such retained strength and voltage is reference application when the above-mentioned example such as shown in figure 12, can know that related coefficient is low, and the error that retained strength is inferred is big.For example, voltage is about 4.4V in the signal of Figure 12, and prediction residual intensity is in 50～95% scope.Because in the secure side evaluation, adopt 50%, be lower than general allowable strength 80% so be evaluated as, become the object that rope is changed.
With respect to this, be shown in figure 13 under the situation of benchmark in relation with area (voltage * data number) and retained strength, prediction area is quafric curve and descends from surpassing 100 scope, and it is very high that related coefficient also becomes.
Under the situation of the value 120 of Figure 13, be estimated as about 90% retained strength, be judged as and use.Wherein, 10% strength degradation takes place, being judged as needs the rope replacing to prepare and make regular check on.
Therefore, we can say relation, rather than the relation of voltage and retained strength is fit closely as the unusual determinating reference of judging with area (voltage * data number) and retained strength.
The waveform of the every operation number of run in certain equipment of Figure 14～16 expression over time, top of each figure is overall waveform, the bottom is a waveform amplification.Use the bottom to ask for area.Figure 14 is that number of run 20,000 times, Figure 15 are 30,000 times, and Figure 16 is 40,000 times.V representes voltage, S expression signal area.
Figure 17 representes the relation of the voltage and the number of run of Figure 14～16, and Figure 18 representes the signal area value of Figure 14～16 and the relation of number of run.These are to be utilized in the program of arbitration functions portion and to ask for automatically.Shown in figure 17, be under about 5V at signal voltage, not too change.With respect to this, the signal area value representation area of Figure 18 increases corresponding to number of run.Figure 19 is the result who has investigated actual broken string situation, can know very consistent with the signal area value.Therefore, the present invention with the relation of such signal area value and number of run as judging key element, the judgement that utilizes the increment rate of waveform to change.
Figure 20 representes the passing of the signal area (signal integration value) of every number of run, and in the Mode A, though from initial certain deterioration that taken place, its increase is little.On the other hand, though in Mode B deterioration take place evening that it increases big.About such variation, tilt to compare with the limit of formulating in advance, the situation that (increases violent) greatly in inclination as Mode B is be evaluated as danger, makes and carries out the judgement that rope is changed.For example, in 60,000 times, the signal area is 200 in the Mode A, is 180 in the Mode B, and Mode A is relatively poor when only estimating with absolute value, but because the inclination of the increase of Mode B is big, so can judge more dangerous than Mode A.When the limit is tilted to be set at 150/ ten thousand time, at 60,000 times time point, being 5,0/0,000 times in the Mode A, is 170/ ten thousand time in the Mode B, has surpassed the replacing benchmark.
Have, the limit tilts to can be used as limit recruitment to be considered again.The longitudinal axis adopts the recruitment (inclination) of signal area among Figure 21, asks for inclination like this, through being judged to be danger above the situation of threshold value, can high precision also learn the rope operating limit exactly.
The result who judges like this sends mails from the computing machine 6a of first monitoring arrangement 6 to second monitoring arrangement 7 as alarm; In the computing machine 6a of second monitoring arrangement 7 that has received; In order to judge having or not of necessity that rope is changed, send the mail of request of data from computing machine 7a.This request msg is view data, numerical data, program etc., and the computing machine 6a of first monitoring arrangement 6 sends the computing machine 7a of this request msg to second monitoring arrangement 7.
In the computing machine 7a of second monitoring arrangement 7, arbitration functions portion resolves the data send here, thereby and then also through the changing in time of data, make final decision with relatively waiting of past data, send to the computing machine 6a of first monitoring arrangement 6.Echo therewith, carry out the preparation of new rope, send expert's etc. measure to the locality.Thus, can change, continue safe work not cause the mode of obstacle to carry out rope the work of local facilities.
In the present invention, " mensuration of rope " is not limited to the situation of burn out detection.Mensuration content beyond the broken string (: determination unit), for example can enumerate corrosion and detect: the fluxoid method, diameter of wire cord reduces: the measuring outside diameter device; Deformation detection: pitch detecting device; Position probing: rotary encoder, tension detection: load cell, extend and measure: displacement meter; Velocity determination: accelerometer, rotation number encoder device, vibration measurement: accelerometer etc.
Figure 22 representes second embodiment of surveillance of the present invention; As determination unit except detecting magnetic leakage fluxes at above-mentioned rope detecting device 3; Also take out the fluxoid data; And configuration measuring outside diameter device 9 sequential test diameter of wire cords on the rope path locate at the pulley place, tension force etc., and these detection signals that convert electric signal into are carried out A/D conversion process and record; With digitizing these data be sent to the computing machine 6a of first monitoring arrangement 6 through WLAN via the data aggregation port, resolve and consider the broken string state and make comprehensive judgement in arbitration functions portion.Figure 23 (a) (b) (c) is illustrated in the variation in time (new product 30,000 times, 50,000 times) of the diameter of wire cord that measuring outside diameter device 9 measures, and can know that periodic diameter reduces in development.
Installation procedure is set evaluate points respectively to broken string and diameter minimizing, corrosion etc. in this case, under the situation that the deterioration that surpasses certain evaluate points is arranged, sends alarm.So long as such structure, telemonitoring necessity and period of changing more accurately just.
Have, rope deterioration in the present invention/unusual judgement is not got rid of the parameter whether voltage has surpassed the maximum voltage of setting, but comprises any of this parameter and above-mentioned two modes and comprehensive judgement of usefulness again.
