Security.Details, which is specifically described, to be realized to the vibration of elevator predicting abnormality method of present embodiment below, below
Content only realizes details for convenience of what understanding provided, not implements the necessary of this programme.
Vibration of elevator predicting abnormality method in present embodiment, as shown in figure 4, specifically including：
Step 401：Receive the vibration data that vibration acquisition device is sent.
Specifically, remote server receives the vibration data that vibration acquisition device is sent, according to the country of GB/T 24474
Standard, the definition of vibration be acceleration magnitude relative to the either large or small phenomenon alternately changed over time of a reference value, that is, shake
Dynamic value is difference of the acceleration magnitude with normal acceleration value of the elevator collected.That is, vibration data can be understood as
It is an acceleration magnitude.
Step 402：Judge whether the vibration data meets preset requirement；If it is, step 403 is performed, if not,
Then enter step 404.
Specifically,《GBT 10058-2009 elevator technology conditions》Regulation, elevator are operated in constant acceleration region
Vertically the maximum peak-to-peak value of (Z axis) vibration not should be greater than 0.30m/s2, and A95 peak-to-peak values not should be greater than 0.20m/s2, A95 peak-to-peak values
The value that the value of i.e. 95% vibration data is less than or equal to, also just says that 95% vibration data not should be greater than 0.20m/s2.Passenger
The maximum peak-to-peak value of horizontal (X-axis and Y-axis) vibration not should be greater than 0.20m/s2 during lift car is run, and A95 peak-to-peak values should not
More than 0.15m/s2, acceleration-deceleration is excessive, and passenger just has the sensation of " overweight " or " weightlessness ", and vibration acceleration is excessive, or
Vibration frequency is in human body sensitive bands, uncomfortable sensations such as passenger just has dizziness, feels sick, while can also produce a large amount of
Noise.Therefore, once the above situation occurs in elevator, reason need to be found out in time, eliminate vibration.Illustrated below by taking Z axis as an example,
The vibration data that preset requirement can be understood as receiving vibrates peak-to-peak value more than 0.30m/s^2 or A95 vibration peak-to-peak values
More than 0.20m/s^2, the vibration data due to meeting preset requirement can directly judge that elevator goes out under current state
Existing failure, therefore whether vibration data this moment occurs that failure does not have actual meaning to prediction elevator, but to analyze,
Record, the vibration data for preserving abnormal preceding certain number of run.403 are entered step if vibration data meets preset requirement,
Vibration data is handled to obtain abnormal vibration prediction proportion, step 404 otherwise can be directly performed, send elevator faults letter
Breath.
Step 403：Vibration data is handled to obtain abnormal vibration prediction proportion.
Specifically, processing procedure can be：Vibration data when being run to elevator, vibration data can be understood as vibrating
The data of reception classify average by peak-to-peak value, for example vibration peak-to-peak value is in 0m/s^2~0.10m/s^2, and 0.10m/s^2~
0.20m/s^2,0.20m/s^2~0.3m/s^2 are averaged respectively, are averaged and are weighted processing again afterwards, and 0m/s^2~
0.10m/s^2 flexible strategy are that 2,0.10m/s^2~0.20m/s^2 is that 3,0.20m/s^2~0.30m/s^2 is 5.The reason so classified
By being, it is that vibration data vibrates peak-to-peak value more than 0.20m/s^2 more than 0.30m/s^2 either A95 that elevator, which occurs abnormal, and
Before reaching the two boundaries, vibration peak-to-peak value when elevator is run is already close to the two boundaries, due to shaking close to boundary
Dynamic peak-to-peak value is more important, therefore bigger closer to two set boundaries, flexible strategy.
Formula is as follows：
A1：The average value of vibration peak-to-peak value in the range of 0m/s^2~0.15m/s^2；
a1n：N-th of vibration peak-to-peak value in the range of 0m/s^2~0.15m/s^2；
n：The number of vibration peak-to-peak value in the range of 0m/s^2~0.15m/s^2.
A2, A3 represent the average value of the vibration peak-to-peak value in the range of 0.10m/s^2~0.20m/s^2,0.20m/s^2 respectively
~0.30m/s^2 vibrates the average value of peak-to-peak value.a2n、a3nSimilarly.
4. S=(A1 × 0.2+A2 × 0.3+A3 × 0.5) × 100
S：Vibrate the weighted value of peak-to-peak value.
After drawing the weighted value of vibration data, the weighted value drawn is differentiated again, if S<2, vibration index is then
For 1, the correspondence of weighted value and vibration index can be as shown in table 1 below.
| Weighted value | Vibration index |
| 0~2 | 1 |
| 3~5.5 | 2 |
| 5.5~8 | 3 |
| 10~12.5 | 4 |
| 12.5~13.5 | 5 |
| 13.5~17 | 6 |
| 17~18 | 7 |
| 18~21 | 8 |
| 21~23 | 9 |
Table 1z shaft vibration index tables
Peak-to-peak value, that is, the value that the vibration peak-to-peak value of 95% collected is less than or equal to, it is desirable to be not more than are vibrated on A95
0.20m/s^2.Accounting of the vibration peak-to-peak value collected more than 0.20m/s^2 is known as Rate.
It is to be understood that as long as vibration index is maintained at 3 or less than 3, then elevator operation is normal, because vibration peak peak
Value is without departing from 0.20m/s^2 excessively；Vibration index 3 is occurred more than, some vibration peak-to-peak values is represented and has been over 0.20m/s^
2.And vibration peak-to-peak value once occur and be more than 0.20m/s^2 more than 0.30m/s^2 or A95 vibration peak-to-peak values, then do not record number
According to because has there is exception in elevator, but to analyze, record, preserving its abnormal preceding certain number of run vibration index and
Rate, such as abnormal preceding vibration index for running 100 times and corresponding Rate.
Abnormal vibration prediction proportion can be drawn by a large amount of abnormal preceding vibration datas come statistical analysis.Present embodiment
Following several analyses are provided and calculate the pre- pycnometric method of abnormal vibration, but are not limited to this in practical applications.Such as
There is the phase answer seizure ratio of abnormal some preceding vibration index, record the phase answer seizure ratio of vibration index, accounting for for vibration index 6 such as occur
Abnormal vibration prediction proportion can be used as than this accounting value.Say, in there are abnormal preceding data, record continuous super for another example
Cross the quantity of some vibration index, continue to exceed some vibration index quantity account for record total quantity proportion can also be used as shake
During dynamic predicting abnormality proportion, such as 77~99 operations, vibration index has been above 7, that is, continuing to exceed vibration index 7 has 23 times,
According to 100 data recorded before, it is 23% that can analyze abnormal vibration prediction proportion.There is a method in which record Rate
The number that state more than 4.5% maintains at least 20 times accounts for the proportion for recording the total degree run.
The specific algorithm of the vibration data on processing z-axis direction is the foregoing described, the vibration data for also having two axis of x, y.
X, y-axis processing mode is identical, and similar to z-axis processing method.It is specific as follows：
Vibration peak-to-peak value when elevator is run, classify average, for example vibration peak-to-peak value is in 0m/s^2~0.07m/s
^2,0.07m/s^2~0.15m/s^2,0.15m/s^2~0.20m/s^2 are averaged respectively, then are weighted processing, 0m/s^
2~0.07m/s^2 flexible strategy are that 2,0.07m/s^2~0.15m/s^2 is that 3,0.15m/s^2~0.20m/s^2 is 5.
2. 3. 4. 5. formula and z-axis processing formula are identical, are specifically shown in formula 1., x, the weighted value of y-axis and vibration index
Correspondence can be as shown in table 2 below.
| Weighted value | Vibration index |
| 0~1.4 | 1 |
| 2.1~4 | 2 |
| 4~5.9 | 3 |
| 7.5~8.75 | 4 |
| 8.75~9.45 | 5 |
| 9.45~11.4 | 6 |
| 11.4~12.75 | 7 |
| 12.75~14.5 | 8 |

Step 404：Send elevator faults information.
Such as if vibration data is unsatisfactory for preset requirement, peak-to-peak value is vibrated with regard to the vibration data for illustrating to receive
Show that event has occurred in the current operating status of elevator more than 0.20m/s^2 more than 0.30m/s^2 or A95 vibration peak-to-peak values
Barrier, remote server can send fault message, remind maintenance personal to carry out maintenance in time, so as to ensure elevator to a certain extent
Safe operation
Step 405：Judge whether abnormal vibration prediction proportion is greater than or equal to early warning proportion；If it is, perform step
406, if it is not, then the flow terminates.
Specifically, early warning proportion is appreciated that those skilled in the art by a large amount of abnormal preceding vibration datas to count
The numerical value drawn is analyzed, the abnormal vibration handled in step 403 is predicted into proportion, is contrasted with early warning proportion, if
Abnormal vibration prediction proportion is greater than or equal to early warning proportion, then although illustrating that elevator shows the state of normal operation at present,
But it is likely to break down, needs to enter step 406 at this time, send warning information.Otherwise represent that elevator is currently in just
Normal state, the possibility to break down afterwards can not handle it also than relatively low.
Step 406：Send warning information.
Such as if abnormal vibration prediction proportion is greater than or equal to early warning proportion, illustrate that elevator has and greatly may
Break down, then remote server can send warning information, prompt maintenance personal to detect the operating status of elevator, and root in time
Adjusted in time according to actually detected result, if being strictly the situation that failure occurs at once, then the timely inspection of maintenance personal
Survey and processing is conducive to avoid the failure that will appear from.
Since early warning proportion is that this area staff is drawn by a large amount of abnormal preceding vibration datas come statistical analysis,
Therefore in practical applications, may slightly have error.Such as remote server can send warning information, maintenance personal is timely
Maintenance elevator is removed, it is found that elevator does not have the trend to break down.And confirm below, gone if based on current early warning proportion
Judgement should send warning information, but maintenance personal goes to detect, it is found that elevator is not faulty, also become without what is broken down
Gesture, then the setting of increase early warning proportion that can be suitably, to adapt to the needs in real life.Such as early warning ratio is reseted
When being set to 1/3, when abnormal vibration prediction proportion is more than 1/3, warning information is sent, notifies testing staff to go to detect.If according to
This early warning proportion goes after detecting a large amount of lift facilities to find without exception, then to feed back and increase early warning proportion, such as send out again to 3/7
Go out warning information.
Compared with prior art, embodiment of the present invention remote server can be according to the vibration data received with regard to pre-
Measure elevator in the process of running it is possible that abnormal conditions, so as to handle it to abnormal, ensure that elevator is transported
Capable security.When need to carry out customary detection to elevator, it is necessary to elevator vibration data when, it is not necessary to remove scene detection device
To obtain vibration data, data only need to be obtained from remote server, save manpower and materials.And with the increasing of data volume
Add, the rule of vibration data can be more and more obvious, and the accuracy that abnormal vibration occurs in prediction elevator can be higher and higher.It is and long-range
