Detailed Description

In order to more clearly understand the technical features, objects and effects of the embodiments of the present application, specific embodiments of the present application will be described with reference to the accompanying drawings.

In automated equipment lines, such as automotive lines, toy lines, and the like, where automated control is required, it is often necessary to closely monitor each of the production components. It is easily understood that in a plant line formed by a plurality of production components, the state of any one component may affect the working state of the entire line. As production continues, the state of each of the produced parts may change. Therefore, data acquisition for the production part also requires timely follow-up adjustments.

For example, during the early stages of production, the acquisition frequency may be slightly lower for some motors and bearings. As production progresses, the frequency of data acquisition for portions of the motor and bearings needs to be increased in order to reduce potential risks. At this time, if the sensor terminal needs to be replaced manually, a corresponding sensor terminal needs to be found from a large number of data acquisition terminals for manual adjustment, which is tedious and prone to error. In practical applications, the adjustment of the collection mode may be required at any time, and the number of production parts involved in the adjustment is also considerable. If both are manually adjusted, the efficiency is very low.

Based on this, the embodiment of the invention provides a data acquisition scheme, which can realize dynamic adjustment of a data acquisition mode according to the real-time working state of an equipment production line, improve the adjustment efficiency and is more convenient. As shown in fig. 1, fig. 1 is a schematic structural diagram of a system according to an embodiment of the present invention. In this schematic, a data collection end 102, a service end 103, a device manufacturing line 104, and a plurality of sensors 101 attached to the manufacturing components of the device manufacturing line 104 for collecting data are included. Of course, this is only an illustration, and in practical applications, the data is not acquired only by the sensor 101.

And the data acquisition end acquires the production environment parameters of the production parts from the equipment production line and sends the production environment parameters to the server end for analysis, and the server end returns a parameter acquisition strategy after analysis so as to facilitate the data acquisition end to adjust the corresponding acquisition mode. In practical applications, data may also be transmitted between the two through an edge gateway (not shown in the figure), which is not limited by the present solution.

As shown in fig. 1, the scheme involves two aspects, namely a data acquisition side and a service side. For the first aspect related to the data acquisition end, a corresponding flow is shown in fig. 2, and fig. 2 is a schematic flow diagram of a data acquisition method provided in an embodiment of the present invention, and is applied to a data acquisition end of an equipment production line including a plurality of production components, where the method specifically includes:

step 201, obtaining a production environment parameter of a production component, where the production environment parameter is used to represent a working state of the production component.

The production environment parameters of a production component may include the generated parameters of its own equipment, such as vibration data, temperature, operating voltage, operating current, withstand pressure, etc. of an equipment; but also parameters that may have an influence on the operating conditions in the environment in which the production component is located, such as the atmospheric temperature, the atmospheric humidity, etc. Whether the working state of a production part is stable or not or whether the working state is abnormal or not can be reflected through the comprehensive production environment parameters.

For example, chain lines in automotive manufacturing contain chain beds (chain bed) that are used to merge the vehicle underbody and the vehicle body. Various stages of acceleration, uniform speed and deceleration are often generated in the merging process, which inevitably causes overall vibration, and the vibration has different performances in different stages. Thus, the current operating state can only be characterized by collecting vibration data.

The production environment parameter may be acquired by a sensor provided on a production part of the equipment line. The corresponding vibration data is obtained, for example, by vibration sensors on the electrodes or bearings. The vibration data may include data relating to the amplitude, frequency, phase, etc. of a device, so that the vibration of the device may be accurately reflected in the form of a sine wave. For another example, the temperature data of the production equipment may be obtained by providing a temperature sensor on the equipment.

The production environment parameters can also be obtained from the environment of the equipment production line. For example, an environmental index of a production plant, which may include, for example, temperature, humidity, air pressure, noise, and aerosol concentration of various particles in the air, is obtained by providing a sensor in the production plant where the equipment production line is located.

The production environment parameters may be obtained from a Programmable Logic Controller (PLC) of the equipment production line. It is common to monitor the operating status of production components on an automated production line via a PLC, and the monitoring is not described herein. For example, the operating current, operating voltage, and on/off status data of the production component can be obtained directly from the PLC.

In practical applications, as the production automation level increases, more and more manual operations are replaced by software automation, and with the continuous development of Operation Technology (OT), Internet Technology (IT) is increasingly involved in supporting equipment production lines for production. Therefore, in a manner of obtaining the production environment parameters, the production environment parameters may also be obtained from the network environment parameters supporting the equipment production line. For example, the data traffic in the communication line of the production line is obtained, the data transmission frequency of a certain communication node is obtained, or the packet loss rate of a certain communication node is obtained.

And 202, filtering the production environment parameters of the production part to generate filtered production environment parameters.

The filtering is to reduce the data volume of the collected original production environment parameters, but the critical information that can characterize the working state is still retained.

In particular, the sensor is constantly acquiring production environment parameters for the production component. However, sometimes the production component may not be started, for example, the non-started production component is represented on the data, that is, the current or voltage is always 0, and then the partial data representing that the production component has not started to work may be filtered.

As another example, some production components may be interrelated in the collected production environment parameters. Such as vibration data of interconnected bearings and crossbars on a machine tool, vibration data of motors and bearings, and so forth. Thus, knowing the vibration data of one, the vibration data of the other can be known. In other words, there is a certain correlation between some production components, and the production environment of other production components can be derived from the production environment parameters of some production components, so that it is not necessary to send the full amount of production environment parameters, but filtering can be performed, so that the filtered production environment parameters can be used to characterize the production environment parameters of the related full amount of production components.

In an embodiment, the characteristic value of the collected signal may be obtained, the characteristic value of the production environment parameter is determined, and the characteristic value is determined as the filtered production environment parameter. The obtaining mode of the characteristic value can be specifically determined according to actual needs.

For example, a characteristic value may be obtained by acquiring data with a common and less variable acquisition frequency, for example, indoor temperature data, possibly every 10 seconds, and then taking an average value of the acquired indoor temperature data in a period of time as the data in the period of time. For example, the average value of the indoor temperature data collected in the first 20 minutes is taken as the indoor temperature data of the first 20 minutes.

For vibration data, for another example, a frequency of 1khz may be acquired, which means 1000 pieces of data per second. Based on this, the vibration data may be signal processed and converted from a time domain signal to a frequency domain signal. Therefore, the energy value of the vibration data on the frequency band is obtained, and an array or a matrix formed by the energy values on each frequency band is determined as the characteristic value of the vibration data, so that the signal amplitude can be greatly compressed, but the working state can still be determined through the characteristic value (namely, the energy value on the frequency band).

And 203, sending the filtered production environment parameters to a server, so that the server generates a parameter acquisition strategy according to the filtered production environment parameters.

The server side receives the filtered production environment parameters, can correspondingly analyze the production environment parameters, determines whether adjustment is needed, generates a corresponding parameter acquisition strategy when needed, and sends the strategy back to the data acquisition side.

And 204, receiving the parameter acquisition strategy returned by the server, and adjusting the acquisition mode of the production environment parameters according to the parameter acquisition strategy.

The data acquisition end can directly execute the parameter acquisition strategy to adjust the acquisition mode of the production environment parameters, or the data acquisition end can also locally preset an acquisition strategy configuration file and modify the acquisition strategy configuration file according to the received acquisition parameters, so that the acquisition mode of the production environment parameters can be adjusted according to the acquisition strategy configuration file.

The adjustment of the acquisition mode may specifically include multiple aspects, which are listed as follows:

first, the acquisition frequency of the production environment parameter for a given production part is adjusted, including increasing the acquisition frequency or decreasing the acquisition frequency. For example, the acquisition frequency of vibration data for one bearing is adjusted from 1khz to 5 khz.

Second, the collection of production environment parameters for a given production component is turned off or on. The designated production part can be one or more, namely, batch opening or closing can be carried out. For example, temperature sensors of a plurality of components that have been operating stably for a past period of time are turned off, or sensors of some components that have been sleeping for a period of time are turned on for data collection.

Third, the correlation of the production environment parameters between the plurality of specified production components is adjusted. For example, the association relationship between two production components having an association relationship is adjusted to be none, or a plurality of production components having no association relationship are adjusted to have an association relationship.

Fourth, the designated production components are turned off or on. For example, when some production parts are judged to be abnormal, the abnormal production parts are instructed to be shut down, so that the vibration data of the production parts are not collected; alternatively, certain designated production components having safety control functions may be turned on so that safety-related data for the designated production components may be monitored, for example, an atmospheric particle detector of a designated diameter may be turned on to collect large particle aerosol concentrations in the plant.

It should be noted that, although various examples of the acquisition mode for adjusting the parameters of the production environment are listed above, in practical applications, it is obviously impossible to exhaust all examples of the adjustment mode. The idea of adjusting the acquisition mode based on the adjustment strategy only needs to be met, and should be considered to be within the solution of the present application.

In an embodiment, the data acquisition end may filter the production environment parameters of the production component based on the association relationship, and generate filtered production environment parameters. As shown in fig. 3, fig. 3 is a schematic flow chart of filtering parameters of a production environment according to an embodiment of the present invention, which includes the following steps:

step 301, determining an association relationship of production environment parameters of a production component, and obtaining a plurality of parameter sets, where the parameter sets include a plurality of production environment parameters having an association relationship.

The production environment parameters in the same parameter set should have the following properties: the production environment parameters of other production components in the parameter set can be obtained through the production environment parameters of some production components, and the number of the parts can be one or more. For example, the production environment parameters of different components having associated relationships may be directly the same, may have a linear relationship with each other, or may have a fitting non-linear relationship, etc.

In the equipment production line, because some motors and bearings are connected and work together, the vibration data of the motors and bearings in a connection relationship have some correlations, or some production parts have a parallel or serial relationship in a production environment, and the corresponding circuit data have some correlations.

For the same reason, in the circuit of the equipment production line, some production components may be in parallel connection, and then the working voltage parameters of the parallel production components can be determined to have the correlation; alternatively, if there may be some production components in series in the circuit of the equipment production line, then the operating current parameters of these parallel production components may be determined to have a correlation.

The data acquisition end can preset an incidence relation configuration file locally for recording the incidence relation of the production environment parameters, so that the production environment parameters with the incidence relation can be obtained from the incidence relation configuration file at any time, and a plurality of parameter sets are obtained.

It is readily understood that there are multiple sets of parameters in a practical application, and that the same production component may be associated with multiple different other production components at different production environment parameters. For example, for a production component a, the production environment parameters include vibration data a1, temperature a2, operating current a3, operating voltage a4, and so on, and it is possible that the vibration data a1 is associated with the vibration data B1 of the production component B, and the operating voltage a4 is associated with the operating voltage of the production component D.

In other words, the association relationship in the embodiment of the present invention is that one parameter of the plurality of production environment parameters included in the production part is associated as the minimum dimension, and not all the production environment parameters of one production part are associated with all the production environment parameters of another production part.

Step 302, for at least one parameter set, filtering out part of the production environment parameters in the parameter set, and generating a non-vacuum true subset of the parameter set.

Since in one parameter set, the production environment parameters of some of the production components in the parameter set can be obtained from the production environment parameters of other production components in the parameter set. Then, the parameter set can be partially filtered at the data acquisition end, so as to obtain a non-empty proper subset of the parameter set.

Step 303, sending the production environment parameters in the non-vacuum subset to a server;

correspondingly, the acquisition end does not send the full amount of production environment parameters any more when sending the production environment parameters, but only sends the production environment parameters in the non-vacuum subset to the server end.

When the server receives the production environment parameters in the non-vacuum subset, the server can also obtain the association relationship among the production environment parameters by using the preset configuration file, and further analyze the association relationship to obtain the total production environment parameters in the parameter set.

Parameter filtering is carried out through the preset incidence relation, the data volume of the data acquisition end and the server end during data transmission can be effectively reduced, and therefore the data transmission cost can be effectively saved.

Further, in the filtering process, one production environment parameter in the parameter set can be selected and reserved, and the rest production environment parameters are filtered to obtain a non-vacuum subset with only one production environment parameter, so that the data transmission quantity can be reduced to the maximum extent.

Further, during the filtering, randomly selected parts of the production environment parameters may be filtered out from the parameter set. For example, 80% of the production environment parameters are randomly selected for filtering, and the influence of partial equipment on the whole production environment parameters can be effectively avoided through a random selection mode, so that comprehensive monitoring is realized.

Further, in the filtering process, the production environment parameters of the pre-specified production component may be retained in the parameter set, and the remaining production environment parameters may be filtered. For example, the production environment parameters of two specified devices in the parameter set are retained, while the other production environment parameters are filtered out. By reserving the production environment parameters of the specified equipment, the effective monitoring of the specified production part can be effectively realized.

The above section describes the data acquisition end of the first aspect. As for the server according to the second aspect in the embodiment of the present invention, as shown in fig. 4, fig. 4 is a schematic flow chart of a data acquisition method applied to the server according to the present invention, and includes the following steps:

step 401, receiving the filtered production environment parameters sent by the data acquisition end, and determining the production environment parameters of the production component according to the filtered production environment parameters.

Since the server receives not the full amount of production environment parameters but only the filtered part of production environment parameters, the server needs to calculate according to the received part of production environment parameters to obtain the full amount of production environment parameters.

Specifically, the server may first directly determine a parameter set to which the received production environment parameters belong according to an association relationship between the production environment parameters (for example, obtained from an association relationship configuration file prestored in the server), so that the full-scale production environment parameters in the parameter set may be assigned according to values of the production environment parameters in the non-aerial subset, and other production environment parameters in the parameter set may be determined. The association relationship has been described in detail above, and is not described in detail here.

For example, for an electrode and a bearing that are related, the relationship between the vibration data may be an empirical functional relationship. For example, the phase and frequency in the vibration data are the same, and the amplitude A_{Electric machine}＝F(A_{Bearing assembly}) Wherein F is an empirical function. The vibration data of the motor can be obtained directly from the vibration data of the bearing according to the empirical formula even if the vibration data received by the service end only has the bearing and does not have the motor.

Similarly, for a plurality of production components having a parallel relationship in the circuit, the received operating voltage of one production component may be determined as the operating voltage of the other production components having a parallel relationship with the operating voltage; for a plurality of production components in a series relationship in the circuit, the received operating current of one production component may be determined as the operating current of the other production component having a parallel relationship with the operating current.

In practice, there may also be more varied or load associations, but in any case as described above. The production environment parameters in the same parameter set should have the following properties: the production environment parameters of other production components in the parameter set can be obtained through the production environment parameters of some production components, and the number of the parts can be one or more. For example, the production environment parameters of different components having associated relationships may be directly the same, may have a linear relationship with each other, or may have a fitting non-linear relationship, etc.

If the received characteristic value is a characteristic value of a certain production environment parameter, since the characteristic value can also be used for reflecting the working state of a production component, the server can directly use the characteristic value as the production environment parameter of the production component at the moment. For example, if the energy value in the frequency domain of the vibration data of a production part is received, the energy value in the frequency domain is directly used as the production environment parameter of the production part.

Step 402, aiming at least one production component, determining the current working state of the production component according to the production environment parameters of the component, and judging the difference degree between the current working state and the preset rated working state.

The nominal operating state of a production component is usually predetermined on the basis of experience. For example, for a production part that is on stream for 7 days, the rated operating current may be 2A; within 15-30 days of putting into production, the rated working current can be 2.05A. In other words, the rated operating state of a production component does not always need to be fixed, and only needs to indicate that the operating state of the production component is stable and normal under the rated operating state.

Generally, the current operating state of any production component may always deviate from the nominal operating state. However, a deviation of a short time does not mean that the device is not normal, and a deviation to a certain extent only indicates that the device has a tendency to develop into an unstable operating state, and even in some cases, a stable oscillation within a small range is instead an expression of a stable operating state.

Therefore, the server needs to comprehensively evaluate the current working state of a production component according to the current production environment parameters. For example, the server side judges the load degree of the equipment according to the temperature difference between the current temperature of the equipment and the atmospheric temperature of the production workshop; for another example, the server judges the vibration amplitude and period of the production component according to the vibration data of the production component in the past period of time; for another example, the server uses the average of the current of a production unit in the past period as the current of the production unit.

Furthermore, the server can perform single-dimensional or multi-dimensional evaluation according to the load degree, vibration amplitude, current working current and other data. For example, from a single dimension, the current working current can be directly compared with the rated working current to determine the difference degree, and the difference degree can be represented by the ratio of the current working current to the rated working current; for another example, from multiple dimensions, the difference degree from the rated operating state in each dimension may be determined, and then the difference degrees in the multiple dimensions are weighted and averaged to obtain the overall difference degree from the rated operating state, or the overall difference degree from the rated operating state may be obtained by directly calculating based on a preset empirical algorithm according to the obtained production environment parameters in the multiple dimensions. The degree of difference can be represented in various forms such as difference, score value, percentage and the like, and the comparison of the scheme is not limited.

And 403, generating a parameter acquisition strategy corresponding to the production component according to the difference degree.

If the difference degree is within an acceptable range (represented by the difference threshold value, i.e. within the difference threshold value range), the server may not generate the parameter collection policy corresponding to the production component, i.e. adjust it.

If the difference degree exceeds the difference threshold value, a parameter acquisition strategy corresponding to the production part needs to be generated, wherein the adjustment degree of the parameter acquisition strategy is positively correlated with the difference degree. In other words, the parameter collection strategy can be divided into a plurality of gears, and the adjustment of the gears is positively correlated with the difference degree. For example, in terms of adjusting the frequency, when the degree of difference is within 1%, it may be considered that the parameter acquisition strategy is not required to be generated; when the difference degree is 1 to 5 percent, the acquisition frequency is considered to need to be properly increased from 1khz to 2 khz; when the degree of difference is 5% to 10%, the acquisition frequency needs to be increased to 5 khz. The specific setting mode can be determined according to actual needs.

In particular, the generated parameter acquisition strategy may include various forms, such as:

when the difference degree does not exceed the difference threshold value within the specified time, generating a parameter acquisition strategy for indicating to close the acquisition of the production environment parameters of the production component;

or when the difference degree does not exceed the difference threshold value within the specified time length, generating a parameter acquisition strategy for indicating to reduce the acquisition frequency of the production environment parameters of the production component, or generating an acquisition strategy for indicating to increase the acquisition time interval of the parameters of the production environment parameters of the production component;

or when the difference degree exceeds a difference threshold value, generating a parameter acquisition strategy for indicating to improve the acquisition frequency of the production environment parameters of the production component;

or, when the difference degree exceeds a difference threshold value by a large margin, namely, the abnormality is possible, a parameter collection strategy for instructing to turn on or off the specified production component is generated, wherein the specified production component can be the production component which generates the production environment parameter, and can also be other production components.

Step 404, the data acquisition end of the parameter acquisition strategy is sent, so that the data acquisition end adjusts the acquisition mode of the production environment parameters of the production component according to the parameter acquisition strategy.
