DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a machine information collection system using a vibration and noise gap pattern according to the present invention will be described in detail.
1 is an overall block diagram of a machine information collection system using a vibration and noise gap pattern according to an embodiment of the present invention.
1, a machine information collection system using a vibration and noise gap pattern according to an embodiment of the present invention includes a
The machine information collection terminal and the machine failure management server communicate with each other through a network to exchange data.
The machine information collecting terminal is attached to one side of the machine. In the case of the machine and the machine information collecting terminal, information is generally exchanged through the data interface unit.
2, a machine
Through the above-described configuration, the system of the present invention can determine the type of failure by using the state check of the machine, the vibration and noise gaps, and provide a preliminary warning before failure and a repair request in case of failure through an alarm , It provides a synergistic effect that enables more precise analysis and diagnosis than when analyzing only vibration information or only noise information.
The
The temperature /
The power
In other words, it controls the switch for interrupting and supplying the power line.
At this time, the vibration
In addition, the sound
The vibration pattern refers to a pattern of how many times a vibration has occurred per a predetermined time, and the noise pattern also refers to a pattern of how many noises have occurred per predetermined time.
At this time, the gaps
For example, the gap value (gap pattern value) refers to an absolute value obtained by subtracting a vibration value (vibration pattern value) from a noise value (noise pattern value).
At this time, the noise value-vibration value, or vibration value-noise value are the same.
However, the units of the noise pattern and the units of the vibration pattern should be matched.
For example, if the vibration is about 5 times as much as the noise, if the vibration is 200 占 퐉 at a certain time, and the noise is 40 dB, the unit is adjusted by adjusting the unit by five times the noise.
As a result, "vibration 200 (mu m) -
As in the above example, the gap is to change dB to 탆 or to change 탆 to dB.
That is, the interval unit is made the same.
On the other hand, by repeating the above pattern, it is possible to calculate the gap pattern for one cycle.
At this time, the
In addition, the
The parameter means various parameter data generated in the machine tool operation.
At this time, the gap
That is, the calculated gap pattern and parameter data are transmitted to the machine failure management server, and the analysis information of the machine is stored and managed in real time.
The alarm
That is, if the failure threshold value is stored as 100 and the warning threshold value is stored as 60, the alarm generation processing unit generates a preliminary action warning alarm when the gap pattern information is less than 60 and less than 60 to 100, , And when it is 100 or more, the repair request alarm information is generated.
At this time, the
3 is a block diagram of a machine failure management server of a machine information collection system using vibration and noise according to an embodiment of the present invention.
As shown in FIG. 3, the machine
A machine
And a
That is, when the machine information obtaining unit obtains the gap pattern information and the parameter data, the information is stored in the machine information database and managed.
In the case of the present invention, the detection of a fault is detected with a gap pattern. The gap pattern means a sound pattern is subtracted from a vibration pattern, or conversely, a sound pattern is subtracted from a sound pattern.
Since the gap pattern is a gap between the sound and the vibration, the gap is determined by hearing the sound of the failure from the vibration at the time of failure, so that it is determined whether the failure is occurring.
These patterns exist within this pattern because 90% of the faults are present because the patterns are recorded and sorted with the information already collected from many machines.
This pattern is recorded and stored in the machine information database to constitute a pattern database.
The present invention can predict how the machine will deviate slightly from the normal pattern (normal pattern) before going to failure.
That is, the patterns are collected within a normal range with a certain tolerance.
Upon reaching any of these thresholds, the administrator of the machine failure management server or the machine manager is given a pre-notify (warning message) before the failure.
Therefore, preventive measures become possible. Once a failure occurs, the work can not be carried out in the field. Therefore, by taking measures in advance, the utilization rate can be maximized.
On the other hand, as shown in FIG. 4, in the case of the vibration pattern, for example, vibrations due to spacing rather than complete coupling between the bolts and the nuts may occur, and a groove may be generated in the machine driving shaft, It will be possible.
At this time, if it is judged by the vibration pattern alone whether there is a failure, it is not known whether the problem is a coupling problem such as an electron or a groove occurred in a machine driving shaft.
However, if the audible pattern is additionally acquired to determine whether the audible sound is defective as in the present invention, the audible sound pattern can be analyzed as a failure corresponding to the problem of the electronic sounding sound. On the other hand, It is possible to analyze the problem that grooves are generated in the in-machine driving shaft.
That is, it is possible to perform more accurate analysis and diagnosis than when measuring with vibration or noise.
In other words, various types of faults can be identified with reference to the gap pattern, which is the difference between the sound and vibration patterns, and if you divide them, you can judge any kind of fault in the machine.
FIG. 5 is a graph illustrating a case in which a vibration value and a noise value interval unit of a machine information collection system using a vibration and noise gap pattern according to an embodiment of the present invention are matched and then subtracted.
As shown in Fig. 5, the unit of noise is dB, and the unit of vibration is mu m, so the units should be matched with each other.
Therefore, since it is 20dB per second and 100μm per second, it is necessary to multiply 20 by 5 times to make it match regardless of the unit.
The unit of the gap pattern is defined as "P ", which is obtained by subtracting the vibration value from the value obtained by multiplying the noise value by 5 times, and expressing it as an absolute value.
That is, P = | vibration value - noise value |
Therefore, it becomes "300" because it is "300-100" in one second, it becomes "0" in "200-200" in 2 seconds, it becomes "300-300" in 3 seconds, Quot; 200-200 " because it is " 400-200 ".
By using the above-described configuration and operation, it is possible to determine the type of failure by using the state check of the machine, the vibration and noise gap pattern, and to provide the pre-failure pre-warning and the repair request in case of failure through an alarm, It provides a synergistic effect that enables more precise analysis and diagnosis than analysis using only information or noise information.
In addition, it provides a synergistic effect for judging various types of failures by judging a gap pattern which is a difference between a sound and a vibration pattern.
It will be appreciated by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is to be understood, therefore, that the embodiments described above are to be considered in all respects as illustrative and not restrictive.
The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents are to be construed as being included within the scope of the present invention do.
