Detailed Description
The embodiment of the application provides a method for detecting the running state of the equipment, and solves the technical problem that the working state of the electrical equipment cannot be effectively identified through audio in the prior art.
In order to solve the technical problems, the general idea of the embodiment of the application is as follows:
a method for detecting the running state of equipment comprises the following steps: randomly combining a plurality of electrical devices in a target electrical room to obtain a plurality of device basic groups; acquiring actual audio in a target electrical room, and determining a device target group corresponding to the actual audio from a plurality of device basic groups; acquiring reference audio of each electrical device in the device target group when the electrical devices normally operate simultaneously; and determining the operation state of each electrical device in the target electrical room according to the actual audio frequency in the target electrical room and the reference audio frequency when each electrical device in the target group of devices normally operates at the same time.
The embodiment groups the electrical equipment in the target electrical room, diagnoses the running state of each electrical equipment in the group by taking the group as a unit and through the actual audio and the reference audio, improves the diagnosis efficiency, reduces the workload of workers, can discover the abnormal condition of the equipment in advance, and avoids irreversible damage to the equipment. According to the embodiment, the running state of the electrical equipment can be diagnosed based on the actual audio and the reference audio without carrying out noise processing on the acquired audio, so that the diagnosis process is simplified, and the diagnosis efficiency is further improved.
In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
First, it is noted that the term "and/or" appearing herein is merely an associative relationship that describes an associated object, meaning that three relationships may exist, e.g., a and/or B, may represent: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
The embodiment provides a method for detecting an operating state of equipment as shown in fig. 1, and the method includes:
and S11, randomly combining a plurality of electrical devices in the target electrical room to obtain a plurality of device basic groups.
In the same electric room, there are many kinds of electric equipment, and the electric equipment generally includes a frequency converter (for example, a converter frequency converter and an oxygen lance frequency converter), a contactor, a reactor, and a low-power equipment for power frequency control. The sound generated when different types of electrical equipment in the electrical room run is different, wherein the sound of the frequency converter and the contactor is larger when the frequency converter and the contactor work normally, and the sound of the reactor and the low-power equipment is almost zero when the reactor and the low-power equipment work normally. The operation time of the electrical devices may be different, for example, the electrical devices with larger sound may operate simultaneously, the electrical devices with smaller sound may operate simultaneously, or the electrical devices with larger sound and the devices with smaller sound may operate simultaneously.
In the embodiment, whether each electrical device is abnormal or not is diagnosed depending on sound, and if a plurality of electrical devices are operated together, overlapping sound may be caused, and for a certain target electrical device, for example, for a frequency converter, when sound of the frequency converter is collected, a contactor is also operated, so that sound of the contactor is included in audio information corresponding to the frequency converter. For the frequency converter, the corresponding audio frequency also includes noise (i.e. the sound of the contactor). However, the noise removal from a piece of audio can be realized by related art means, but the effect of noise removal varies with the quality of the acquired audio. In the embodiment, audio is acquired in an electrical room, and noise in the electrical room is more (for a frequency converter, sound generated by other electrical equipment is noise), and the audio acquisition environment is poor, so that the quality of the acquired audio is poor, and if a noise removing means is used, the removing effect is poor, so that the working state of the electrical equipment cannot be correctly diagnosed.
The embodiment avoids using a noise removal means, and groups the electrical devices in the electrical room to obtain a plurality of basic groups of devices, wherein the electrical devices in one basic group of devices are in simultaneous operation. That is, any one of the electrical devices in the target electrical room may be in a plurality of device elemental groups at the same time.
In step S11, a plurality of electrical devices in the target electrical room are randomly combined to obtain a plurality of device basic groups, specifically including step S21 and step S22.
And S21, dividing the plurality of electrical equipment in the target electrical room into a plurality of equipment clusters according to the position distribution of the plurality of electrical equipment in the target electrical room and the sample audio frequency when each of the plurality of electrical equipment is independently and normally operated.
The embodiment determines whether the electrical equipment is abnormal or not depending on the sound generated when the electrical equipment runs, and the sound is related to the distance of the detection position where the sound detection equipment is located; and the electrical equipment in the electrical room is more, the sound generated by each electrical equipment can also influence each other, the larger the sound is, the larger the influence is, and further, according to the position distribution and the sample audio frequency when each electrical equipment normally operates, the electrical equipment is divided into a plurality of equipment clusters.
Specifically, step S21 specifically includes steps S31 to S36.
Step S31, a sample audio of each of the plurality of electrical devices when the electrical device operates normally alone is acquired.
Each electrical device is correspondingly provided with a special sound collecting device, and sample audio in independent normal operation is collected through the special sound collecting devices. For example, as shown in fig. 2, the target electrical room includes a transducer and a contactor, and the contactor is not operated when the sample audio of the transducer is collected, and the transducer is not operated when the sample audio of the contactor is collected.
And step S32, determining the average volume of each electrical device according to the sample audio of each electrical device.
The audio frequency is a wave, and the wave includes a frequency and an amplitude, wherein the frequency is represented by the pitch and the amplitude is represented by the volume. While the sounds produced by different types of electrical equipment are mainly distinguished by volume. For example, the transducer and contactor are loud when operating, while low power devices operate with little sound. Therefore, the present embodiment determines the average volume of each electrical device from the sample audio of each electrical device.
And step S33, dividing the plurality of electrical devices into a first electrical device group and a second electrical device group according to the average volume of each electrical device, wherein the average volume of the electrical devices in the first electrical device group is larger than the average volume of the electrical devices in the second electrical device group.
According to the volume of each electrical device, the first electrical device group with larger volume and the second electrical device group with smaller volume are divided.
Step S34, obtaining the position distribution of at least two electrical devices in the first electrical device group.
Because the electrical equipment in the second electrical equipment group has small or no sound during operation, the electrical equipment in the second electrical equipment group is usually not collected by the sound collection equipment corresponding to the first electrical equipment group. In contrast, when the first electrical device group operates, the sound of each electrical device in the first electrical device group is relatively large, the sound collection devices corresponding to the electrical devices in the first electrical device group and the second electrical device group are affected, and the influence of the sound is closely related to the distance of the position, so that the position distribution of each electrical device in the first electrical device group can be obtained only, and the electrical devices in the first electrical device group are further divided.
Step S35, performing area division on the at least two electrical devices in the first electrical device group according to the position distribution of the at least two electrical devices in the first electrical device group, to obtain a plurality of area device groups.
Specifically, the electrical devices in the first electrical device group whose separation distance is smaller than the preset distance threshold may be divided into one zone device group, and then a plurality of zone device groups may be obtained.
And step S36, obtaining a plurality of equipment clusters according to the plurality of regional equipment groups and the second electrical equipment group.
The plurality of regional equipment groups are used as a plurality of equipment clusters, the second electrical equipment group is used as one electrical equipment cluster, and then a plurality of equipment clusters can be obtained.
For example, as shown in fig. 2, the target electrical room includes a converter frequency converter, an oxygen lance frequency converter, a first small power device, a second small power device, a first large contactor device and a second large contactor device, and a corresponding sound collection device is installed for each electrical device, for example, the converter frequency converter corresponds to the first sound collection device. The converter frequency converter, the oxygen lance frequency converter, the first large contactor device and the second large contactor device belong to devices with larger sound, and the first low-power device and the second low-power device belong to devices with smaller sound or even silence. When all the electrical equipment in the figure 2 runs simultaneously, the converter frequency converter and the oxygen lance frequency converter are close to each other, and the mutual influence between the converter frequency converter and the oxygen lance frequency converter is large. The first low-power device is close to the converter frequency converter, but the first low-power device does not affect the first sound collecting device of the converter frequency converter because the sound of the first low-power device is small or even silent, and conversely, the converter frequency converter has a large sound and affects the third sound collecting device of the first low-power device. Converter and first big contactor equipment distance are far away, but because sound is all great when both move, still can cause the influence to first sound collection equipment and fifth sound collection equipment, and only first big contactor equipment is to the influence of first sound collection equipment, for the influence of oxygen rifle converter to first sound collection equipment, not so big.
Therefore, the converter frequency converter, the oxygen lance frequency converter, the first large contactor and the second large contactor can be divided into a first electrical equipment group, and the first low-power equipment and the second low-power equipment can be divided into a second electrical equipment group. In fig. 2, three equipment clusters are further formed by dividing the converter and the lance converter, which are closer to each other, in the first electrical equipment group into one equipment cluster (referred to as a first cluster), dividing the first large contactor and the second large contactor, which are closer to each other, in the first electrical equipment group into another equipment cluster (referred to as a second cluster), and using the second electrical equipment group as one equipment cluster (referred to as a third cluster).
And S22, randomly combining the electric equipment in the equipment clusters to obtain a plurality of equipment basic groups.
A basic group of devices, which is composed of one or more electrical devices, is obtained from each of a plurality of device clusters.
Taking the electrical equipment shown in fig. 2 as an example, one electrical equipment may be extracted from one cluster (for example, the converter is extracted from the first cluster) to form one basic equipment group, or a plurality of electrical equipment may be extracted from one cluster (for example, the converter and the lance converter are extracted from the first cluster) to form one basic equipment group. One or more devices may also be extracted from any two clusters to form a basic group of devices, and so on.
The greater the number of electrical devices in the target electrical room, the greater the number of basic groups of devices resulting from random combinations. In the embodiment, typical electrical equipment can be combined to form an equipment basic group according to actual production requirements. Atypical combinations of electrical devices are not considered as a basic group of devices. For example, as shown in fig. 2, for the third cluster, no matter the basic group of devices is formed by the first low-power device alone, the basic group of devices is formed by the second low-power device alone, or the basic group of devices is formed by both the first low-power device and the second low-power device, since the low-power device has a small sound or even no sound, there is no influence on other devices, and the low-power devices can be directly divided into the same basic group of devices, so as to reduce the total number of the basic groups of devices, reduce the size of data, and improve the efficiency of querying the basic group of devices in the later stage.
After step S11 is executed, step S12 is executed.
And S12, acquiring actual audio in the target electrical room, and determining a device target group corresponding to the actual audio from the plurality of device basic groups.
The actual audio frequency in the target electrical room may be collected continuously or at preset intervals during operation of the electrical equipment in the target electrical room. And acquiring the actual audio frequency of the target electrical room, wherein the actual audio frequency of each electrical device in the target electrical room is actually acquired. In order to more accurately collect the actual audio frequency of each electrical device in the target electrical room, one or more sound collection devices may be respectively disposed for each electrical device, as shown in fig. 2, for collecting the actual audio frequency. That is to say, the actual audio in the target electrical room in this embodiment refers to the actual audio collected by the sound collection device corresponding to the target electrical device in each electrical device when each electrical device in the device target group operates simultaneously.
For example, when the converter frequency converter and the first large contactor operate simultaneously, for the converter frequency converter, the first sound collecting device corresponding to the converter frequency converter collects the first actual audio when the converter frequency converter and the first large contactor operate simultaneously, and the installation position of the first sound collecting device corresponding to the converter frequency converter is necessarily very close to the converter frequency converter and is far from the first large contactor. Then for the first actual audio, the sound produced by the converter transducer is the target sound, while the sound produced by the first large contactor is noise. Similarly, for the first large contactor, the sound generated by the first large contactor in the second actual audio collected by the fifth sound collection device is the target sound, and the sound generated by the converter frequency converter is the noise.
In order to determine which devices are specifically included in the electrical devices generating the actual audio, the switch states of the electrical devices in the target electrical room can be acquired from the industrial personal computer, the electrical devices with the switch states being on are selected, the selected electrical devices are matched with the plurality of device basic groups obtained in step S11, and the corresponding device target groups are selected from the plurality of device basic groups.
For example, when the converter frequency converter and the first large contactor operate simultaneously, the basic group of the equipment corresponding to the converter frequency converter and the first large contactor is the target group of the equipment.
And S13, acquiring the reference audio of each electrical device in the device target group when the electrical devices simultaneously and normally operate.
After step S11 is executed, for each basic device group in the multiple basic device groups, reference audio of each electrical device in each basic device group in normal operation at the same time may be collected, and the reference audio of each basic device group may be stored. The reference audio of each basic group of the devices refers to the reference audio corresponding to each electrical device when each electrical device is in normal operation. For example, the basic device group includes a converter and a first large contactor, and the reference audio of the basic device group refers to a first reference audio collected by a first sound collection device corresponding to the converter and a second reference audio collected by a fifth sound collection device corresponding to the first large contactor when the converter and the contactor operate simultaneously.
After step S13 is executed, that is, after the device target group is determined, the reference audio corresponding to each of the electric devices in the device target group is acquired from the stored reference audio.
And S14, determining the operation state of each electrical device in the target device group according to the actual audio frequency in the target electrical room and the reference audio frequency when each electrical device in the target device group operates normally at the same time.
The comparison may be based on a difference value between the actual audio and the reference audio, such as a difference value, a ratio value, and the like. The matching degree between the two audio signals may be compared, for example, for each electrical device in the device target group, the reference audio obtained in step S13 and the actual audio obtained in step S12 are compared to determine the matching degree between the two audio signals. And determining the operation state of each electrical device in the device target group according to the matching degree. The essence of the method is that the actual audio of each electrical device in the device target group is matched with the corresponding reference audio to obtain the matching degree, and then the running state of each electrical device in the device target group is determined.
For example, when the converter frequency converter and the first large contactor operate simultaneously, for the converter frequency converter, a first actual audio frequency acquired by the first sound acquisition device is matched with a corresponding first reference audio frequency to obtain a first matching degree, and the operating state of the converter frequency converter is determined through the first matching degree. And for the first large contactor, matching a second actual audio acquired by the fifth sound acquisition equipment with a corresponding second reference audio to obtain a second matching degree, and determining the running state of the first large contactor according to the second matching degree.
When the matching degree is lower than a preset matching threshold value, the fact that the operation of the electrical equipment is abnormal is determined, a corresponding alarm device can be set, alarm is triggered, a worker is prompted to stop the machine for detection, potential safety hazards caused by long-term operation of the electrical equipment in an abnormal state are avoided, irreversible damage to the electrical equipment can be avoided, and the service life of the electrical equipment is prolonged. And when the matching degree exceeds a preset matching threshold, determining that the electrical equipment is not abnormal in operation and can continuously and normally operate.
It should be noted that, in this embodiment, the actual audio of each electrical device is not compared with the reference audio of each electrical device when the electrical device is operating alone normally, but the actual audio of each electrical device when the electrical devices are operating simultaneously is compared with the reference audio of each electrical device when the electrical devices are operating normally, so that the influence of noise in the audio on the diagnosis of the operating state of the electrical devices is avoided.
In this embodiment, when the converter frequency converter and the first large contactor operate simultaneously, the actual audio frequency of each electrical device and the reference audio frequency of each electrical device when the converter frequency converter and the first large contactor operate simultaneously only need to be compared, and noise removal processing is not needed to be performed on the converter frequency converter and the first large contactor, so that whether the converter frequency converter and the first large contactor are abnormal or not can be determined, the diagnosis process of the electrical device is simplified, the diagnosis difficulty is reduced, and the diagnosis efficiency is improved. Moreover, the number of times of manual inspection can be reduced, and the labor intensity of workers can be further reduced.
When the device target group is the second electrical device group, it is also possible to determine whether the electrical devices in the second electrical device group are abnormal in the following manner.
When the device target group is a second electrical device group, the method further comprises:
and S41, determining the maximum value of the volume of each electrical device in the second electrical device group according to the sample audio of each electrical device in the second electrical device group.
And S42, determining a preset upper limit threshold value of each electrical device in the second electrical device group according to the maximum value of the volume of each electrical device in the second electrical device group.
And S43, determining the operation state of each electrical device in the second electrical device group according to the actual audio frequency of each electrical device in the second electrical device group and the preset upper limit threshold of each electrical device in the second electrical device group.
The electrical devices in the second electrical device group are mainly low-power electrical devices, and the sound of the electrical devices is small, even no sound exists, so that when the actual audio frequency during the operation of the electrical devices is collected, the interference caused by other electrical devices with large sound is large. If the actual audio frequency is compared with the reference audio frequency, although the operation state of the electrical equipment in the second electrical equipment group can be identified, the accuracy rate is greatly reduced. In order to improve the diagnosis accuracy of the low-power device, steps S41 to S43 are provided according to the sound abnormality characteristic of the low-power device.
