[0056] As described above, how to improve the data processing efficiency of the mechanical vibration data has become a technical problem to be solved by those skilled in the art.
[0057] In the prior art, a mechanical vibration signal of a mechanical equipment is collected by a data collection device to obtain mechanical vibration data, and the mechanical vibration data is processed, and the processed data is sent to a data detection device for mechanical vibration detection. However, the inventors have found that this method has strict requirements for the data collection device, which needs to have the functions of data collection and data processing. That is, the data collection device performs data processing during data collection, and both data collection and data processing need to occupy the device memory and processor resources of the data collection device, resulting in low data processing efficiency.
[0058] Therefore, the data collection function and the data processing function are separated in the present application, and data collection is performed by a data collection device, and conversion and normalization are performed by a data processing device. That is, data processing occupies the device memory and processor resources of the data processing device, and does not need to occupy the device memory and processor resources of the data collection device together with data collection, thereby improving the data processing efficiency.
[0059] For example, one of the scenarios of the embodiments of the present application can be applied to the scenario as shown in FIG. 1. Figure 1 The scenario includes a data collection device 101, a data processing device 102 and a data detection device 103. The data collection device 101 and the data processing device 102 interact with each other, and the data processing device 102 and the data detection device 103 interact with each other.
[0060] The data collection device 101 collects the mechanical vibration signal of the mechanical equipment to be detected through a sensor, and sends the plurality of first mechanical vibration data to the data processing device 102. The data processing device 102 receives the plurality of first mechanical vibration data sent by the data collection device 101, converts the plurality of first mechanical vibration data into a plurality of second mechanical vibration data according to the hardware parameters of the data processing device and the sensitivity of the sensor, performs normalization processing on the plurality of second mechanical vibration data according to the sampling frequency of the sensor to obtain a plurality of third mechanical vibration data, and sends the plurality of third mechanical vibration data to the data detection device 103. The data detection device 103 receives the plurality of third mechanical vibration data and performs mechanical vibration detection on the plurality of third mechanical vibration data.
[0061] First, in the above application scenario, although the actions of the embodiments provided by the present application are described as being performed by the data processing device 102, the present application is not limited in terms of the execution subject, as long as the actions disclosed in the embodiments provided by the present application are performed.
[0062] Second, the above scenario is only an example of a scenario provided by the present application, and the present application is not limited to this scenario.
[0063] In order to make the personnel in the technical field better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor fall within the scope of protection of the present application.
[0064] The embodiment of the present application provides a mechanical vibration data processing method, which is executed by a data processing device and includes steps 201-204. Referring to Figure 2 The figure is a flowchart of a mechanical vibration data processing method provided by the embodiment of the present application.
[0065] Step 201: receiving a plurality of first mechanical vibration data sent by a data acquisition device, wherein the plurality of first mechanical vibration data is obtained by the data acquisition device through a sensor collecting a mechanical vibration signal of a mechanical equipment to be detected.
[0066] Mechanical vibration data monitoring is mainly used for detecting the mechanical vibration state of various mechanical equipment, such as detecting whether a steam turbine, a water turbine, a compressor, a motor, a gear and a bearing appear mechanical vibration failure and whether there is a mechanical vibration hidden danger. In actual application, the data acquisition device is usually arranged at an engineering or industrial site, the sensor is arranged at a detection point of the mechanical equipment to be detected, and the data acquisition device collects the mechanical vibration signal of the mechanical equipment to be detected through the sensor to obtain the plurality of first mechanical vibration data.
[0067] Since the requirement for the data acquisition device in the prior art is relatively strict, it needs to simultaneously have functions of data acquisition and data processing. In the process of collecting the plurality of first mechanical vibration data by the data acquisition device, the plurality of first mechanical vibration data is simultaneously processed. Both the data acquisition and the data processing need to occupy the device memory and the processor resource of the data acquisition device, which leads to low data processing efficiency.
[0068] Therefore, in the embodiment of the present application, in order to avoid that both the data acquisition and the data processing need to occupy the device memory and the processor resource of the data acquisition device, the data acquisition device can send the plurality of first mechanical vibration data to a data processing device, and then the data processing device receives the plurality of first mechanical vibration data, so as to subsequently process the plurality of first mechanical vibration data by the data processing device.
[0069] In addition, in the embodiment of the present application, one data acquisition device can be connected with a plurality of sensors, and the data processing device can be connected with a plurality of data acquisition devices to receive the plurality of first mechanical vibration data sent by the plurality of data acquisition devices through multicast technology.
[0070] Step 202: converting the plurality of first mechanical vibration data into a plurality of second mechanical vibration data according to the hardware parameters of the data processing device and the sensitivity of the sensor.
[0071] After receiving the plurality of first mechanical vibration data in step 201, in order to facilitate subsequent mechanical vibration detection, the digital signal needs to be converted into an analog signal based on the plurality of first mechanical vibration data being generally digital signals. Based on this, for the plurality of first mechanical vibration data, the plurality of first mechanical vibration data can be converted to obtain the plurality of second mechanical vibration data representing the analog signal according to the hardware parameters of the data processing device and the sensitivity of the sensor.
[0072] Step 203: normalizing the plurality of second mechanical vibration data according to the sampling frequency of the sensor to obtain a plurality of third mechanical vibration data.
[0073] After converting the plurality of first mechanical vibration data into the plurality of second mechanical vibration data in step 202, in order to obtain the waveform data of the mechanical vibration, the plurality of second mechanical vibration data also needs to be normalized according to the sampling frequency of the sensor to obtain the plurality of third mechanical vibration data.
[0074] In the implementation of step 203, the sampling frequency of the sensor represents the amount of data collected by the sensor per second, for example, the sampling frequency of the sensor is 2048 Hz, that is, the sensor collects 2048 first mechanical vibration data per second, and then 2048 second mechanical vibration data is obtained through steps 101 and 102. According to the sampling frequency of the sensor, the 2048 second mechanical vibration data is normalized to obtain 2048 third mechanical vibration data.
[0075] In the embodiment of the present application, the data acquisition function and the data processing function are separated, and the data acquisition is performed by the data acquisition device, and the conversion, normalization and other data processing are performed by the data processing device; that is, the data processing occupies the device memory and processor resources of the data processing device, without occupying the device memory and processor resources of the data acquisition device with the data acquisition, thereby improving the data processing efficiency.
[0076] In addition, in the embodiment of the present application, the data acquisition device does not need to have the conversion, normalization and other data processing functions, which can reduce the data processing pressure of the data acquisition device in the prior art, and at the same time, the performance requirement of the data acquisition device is reduced, thereby the device cost and maintenance cost of the data acquisition device are also reduced.
[0077] Step 204: sending the plurality of third mechanical vibration data to the data detection device, so that the data detection device performs mechanical vibration detection on the plurality of third mechanical vibration data.
[0078] After obtaining the plurality of third mechanical vibration data in step 203, in order to realize mechanical vibration detection by the subsequent data detection device, the plurality of third mechanical vibration data also needs to be sent to the data detection device, so that the data detection device can realize mechanical vibration detection through the plurality of third mechanical vibration data.
[0079] The embodiment of the present application performs data acquisition by the data acquisition device, and performs data processing such as conversion and normalization by the data processing device. Therefore, the data processing occupies the device memory and processor resources of the data processing device, and does not need to occupy the device memory and processor resources of the data acquisition device together with the data acquisition, thereby improving the data processing efficiency. At the same time, since the data acquisition device does not need to perform data processing, the performance requirement of the data acquisition device is reduced, and the maintenance difficulty, procurement cost and maintenance cost of the data acquisition device are also reduced, thereby solving the problems of difficult maintenance and high cost of the data acquisition device in the prior art.
[0080] In an embodiment of the present application, the above step 202 can be realized by steps 301-302.
[0081] Step 301: converting the plurality of first mechanical vibration data into a plurality of voltage signals according to the hardware parameters.
[0082] Specifically, the plurality of first mechanical vibration data is converted into a plurality of voltage signals according to the hardware parameters of the data processing device, as shown in formula (1):
[0083] U=(S / a*b+b)*c (1)
[0084] In the formula, U is voltage, the unit is V; S is the plurality of first mechanical vibration data; a is the code value of analog-to-digital conversion; b and c are conversion coefficients, which are related to the hardware circuit layout of the data processing device.
[0085] In particular, when the plurality of first mechanical vibration data is a 16-bit signed number, a=32767.
[0086] Step 302: converting the plurality of voltage signals into the plurality of second mechanical vibration data according to the sensitivity.
[0087] Specifically, the plurality of voltage signals are converted into the plurality of second mechanical vibration data according to the sensitivity, as shown in formula (2):
[0088] D=U*d / K (2)
[0089] wherein D is the second mechanical vibration data; d is a coefficient; and K is the sensitivity of the sensor.
[0090] The embodiment of the present application converts the digital signal into an analog signal through steps 301-302, so as to obtain the plurality of third mechanical vibration data through subsequent normalization processing.
[0091] In an embodiment of the present application, the step 203 can be implemented through steps 401-402.
[0092] Step 401: According to the sampling frequency, the plurality of second mechanical vibration data is subjected to mean value processing to obtain mean value data.
[0093] According to the sampling frequency, the data amount of the first mechanical vibration data collected by the sensor per second can be obtained. For example, if the sampling frequency of the sensor is 2048 Hz, 2048 first mechanical vibration data per second are obtained, corresponding to 2048 second mechanical vibration data. The 2048 second mechanical vibration data is subjected to mean value processing to obtain mean value data, as shown in formula (3):
[0094]
[0095] wherein, is the mean value data, Xi is the i-th second mechanical vibration data.
[0096] Step 402: Difference operation is performed on the plurality of second mechanical vibration data and the mean value data to obtain a plurality of third mechanical vibration data.
[0097] Difference operation is performed on the plurality of second mechanical vibration data and the mean value data, as shown in formula (4):
[0098]
[0099] wherein, Xi is the i-th third mechanical vibration data.
[0100] In an embodiment of the present application, the step 202 can be implemented through steps 501-502.
[0101] Step 501: According to the first preset data range, the plurality of first mechanical vibration data is subjected to screening to obtain a plurality of screened data.
[0102] Generally, the first mechanical vibration data has a certain data range, a reasonable first preset data range is set in advance, and the first mechanical vibration data exceeding the first preset data range can be considered as abnormal first mechanical vibration data. Therefore, in order to remove the abnormal first mechanical vibration data in the plurality of first mechanical vibration data, so as to prevent the abnormal first mechanical vibration data from affecting the subsequent mechanical vibration detection accuracy, it is necessary to screen the plurality of first mechanical vibration data according to the first preset data range, and obtain a plurality of screened data.
[0103] Step 502: converting the plurality of screened data into the plurality of second mechanical vibration data according to the hardware parameters and the sensitivity.
[0104] In the embodiment of the application, the abnormal first mechanical vibration data is screened out to obtain a plurality of screened data, and the plurality of screened data is converted into the plurality of second mechanical vibration data, thereby improving the accuracy of subsequent mechanical vibration detection.
[0105] In an embodiment of the application, the plurality of first mechanical vibration data is obtained by screening a plurality of collected mechanical vibration data collected by the sensor according to a second preset data range. Then, the data processing device can receive the plurality of first mechanical vibration data screened, so as to improve the accuracy of the third mechanical vibration data.
[0106] In an embodiment of the application, on the basis of steps 201-203, before step 204, steps 601-602 are further included.
[0107] Step 601: obtaining a device running parameter of the mechanical equipment to be detected.
[0108] The device running parameter of the mechanical equipment to be detected can be used for subsequent mechanical vibration monitoring and analysis of the mechanical equipment to be detected.
[0109] Step 602: associating the plurality of third mechanical vibration data with the device running parameter.
[0110] By associating the plurality of third mechanical vibration data with the device running parameter of the mechanical equipment to be detected, the corresponding relationship between the plurality of third mechanical vibration data and the device running parameter of the mechanical equipment to be detected can be known. Especially in the case that the data processing device receives a plurality of first mechanical vibration data corresponding to a plurality of mechanical equipment to be detected, and obtains a plurality of third mechanical vibration data corresponding to a plurality of mechanical equipment to be detected, associating the plurality of third mechanical vibration data with the device running parameter of the mechanical equipment to be detected facilitates the subsequent mechanical vibration detection of the data detection device on the mechanical equipment to be detected.
[0111] Correspondingly, the step 204 can be implemented by sending the plurality of third mechanical vibration data and the device operation parameters associated with the plurality of third mechanical vibration data to the data detection device.
[0112] In an embodiment of the present application, the step 204 is implemented by step 701.
[0113] Step 701: sending the plurality of third mechanical vibration data to a database, so that the database provides the plurality of third mechanical vibration data to the data detection device.
[0114] The plurality of third mechanical vibration data can be stored in a database with high security, for example, MySQL. Thus, the security and reliability of the data are greatly improved.
[0115] The present application also provides a device for processing mechanical vibration data, which is shown in Figure 3 The figure is a structural schematic diagram of a device for processing mechanical vibration data according to an embodiment of the present application.
