Detailed Description

For the purpose of promoting an understanding of the principles and advantages of the disclosure, reference will now be made in detail to the drawings, in which it is apparent that the embodiments described are only some, but not all embodiments of the disclosure. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.

The term "and/or" in the embodiments of the present disclosure describes an association relationship of association objects, which means that three relationships may exist, for example, a and/or B may represent: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

The terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present disclosure, unless otherwise indicated, the meaning of "a plurality" is two or more.

In the description of the present disclosure, it should be noted that, unless explicitly stated and limited otherwise, the term "coupled" should be interpreted broadly, for example, as being directly coupled, or indirectly coupled through an intermediary, as being in communication with the interior of two devices. The specific meaning of the terms in this disclosure will be understood by those of ordinary skill in the art as the case may be.

The components and the working fluid in the hydraulic system work in a closed oil circuit, so that the fault of the hydraulic system is generally complex and hidden, and the working failure of the hydraulic system can be caused after the hydraulic system breaks down. In the related art, parameters such as pressure at certain positions of a hydraulic system and flow of working fluid are measured, and compared with preset values to judge whether the hydraulic system has faults.

However, the above solution only determines that the hydraulic system has failed if a single parameter exceeds a corresponding preset value. As mentioned above, the failure of the hydraulic system is generally complex and hidden, and even if a single parameter does not exceed a corresponding preset value, the hydraulic system may experience a hidden failure or may be of poor performance. Therefore, the scheme is difficult to determine the faults when the hydraulic system has hidden faults, so that the hydraulic system has more serious faults; it is also difficult to determine the performance of the hydraulic system and the hydraulic system cannot be maintained in time when the performance of the hydraulic system is poor.

In order to accurately determine the performance of a hydraulic system, the embodiment of the disclosure provides a method, a device, a system and a storage medium for monitoring the hydraulic system. The following describes the technical solutions of the present disclosure and how the technical solutions of the present disclosure solve the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present disclosure will be described below with reference to the accompanying drawings.

Referring to fig. 1B, the hydraulic system 100 includes a power element 110, an actuator 120, a control assembly 130, accessories, and hydraulic oil flowing through the components (the accessories and the hydraulic oil are not shown in the drawing), where the power element 110 corresponds to a pressure sensor 1, a flow sensor 1, and a displacement sensor 1, and the actuator 120 corresponds to a pressure sensor 2, a flow sensor 2, and a displacement sensor 2. The controller in the control module 130 controls the opening degrees of the various hydraulic valves in the control module based on the control parameters, thereby changing the flow direction of the hydraulic oil.

Fig. 1B is merely an illustration of a possible implementation manner of the hydraulic system, and the embodiment is not limited to the elements specifically included in the hydraulic system, the sensor types corresponding to each element, the number of sensors corresponding to each element, and the like.

In some embodiments, the hydraulic system 100 may send the sensor-generated data and the controller-generated data to the monitoring system 200.

The above application scenario is only an example of the embodiment of the present invention, and the embodiment of the present invention is not limited thereto.

Referring to fig. 2, a system architecture diagram of the monitoring system 200 is shown, where the monitoring system 200 includes an electronic device 210 and a terminal 220.

The hydraulic system 100 may send the data generated by the sensors and the data generated by the controller to a terminal 220 in the monitoring system.

The terminal 220 may convert the received data generated by the sensor and the data generated by the controller into data of the hydraulic system;

the converted hydraulic system data may also be sent to the electronic device 210.

The electronic device 210 may select first target data from data of the hydraulic system, where the first target data includes data acquired during a target period of time and acquired through a sensor corresponding to an element of the hydraulic system, and control information of the hydraulic system acquired during the target period of time;

the first target data may be arranged based on the acquisition time of the first target data to obtain target sequence data;

the target sequence data and the environmental information in the target duration can be input into a first target model to obtain evaluation information representing the performance of the hydraulic system.

The electronic device 210 may be in data communication with the terminal 220 via a variety of communication means, such as a local area network (Local Area Network, LAN), a wireless local area network (Wireless Local Area Network, WLAN) and other networks. For example: the terminal 220 transmits data of the hydraulic system to the electronic device 210 through the WLAN.

In some specific embodiments, the electronic device 210 may manage configuration information of the terminal 220 and the hydraulic device, and the terminal 220 receives the configuration information sent by the electronic device 210.

The electronic device 210 may include one or more groups of servers, which may be one or more types.

The terminal 220 is a device with data transmission capability, and the specific implementation manner of the terminal 220 is not limited in this embodiment.

Fig. 3 is a schematic flowchart of a first method for monitoring a hydraulic system according to an embodiment of the disclosure, which is applied to the electronic device, as shown in fig. 3, and the method may include:

step 301: first target data is selected from data of the hydraulic system.

The first target data comprise data acquired in a target time period and acquired through sensors corresponding to elements of the hydraulic system, and control information of the hydraulic system acquired in the target time period.

As described above, the hydraulic system includes a plurality of elements, each element having a different sensor. According to the embodiment, according to the data acquired by the sensor corresponding to the element and the control information of the hydraulic system, which are acquired in a period of time, the change of the data (such as temperature, pressure, flow and displacement) acquired by the sensor under the control information in the period of time can be obtained, and the change can represent the performance of the hydraulic system, such as:

Under the same control information, the received pressure acquired by the pressure sensor corresponding to the executing element is higher and higher, and even if the current hydraulic system does not have faults, the performance of the hydraulic system is also problematic.

The example is only for illustrating that the change of the first target data reflects the performance of the hydraulic system to a certain extent, and in practical application, the situation that the pressure collected by the pressure sensor corresponding to the actuator is higher and higher is not necessarily generated.

In this embodiment, the first target data may include data acquired in a target time period and acquired by a sensor corresponding to a certain element of the hydraulic system, and control information of the hydraulic system acquired in the target time period;

alternatively, the first target data may include data acquired during a target period of time and acquired through sensors corresponding to a part of elements of the hydraulic system, and control information of the hydraulic system acquired during the target period of time;

alternatively, the first target data may include data acquired by sensors corresponding to all elements of the hydraulic system acquired during the target period, and control information of the hydraulic system acquired during the target period.

The foregoing is an exemplary description of the first target data, and it may be determined which hydraulic system data is to be used as the first target data according to the actual application scenario.

In addition, the target duration may be set according to an actual application scenario.

The manner of acquiring the data of the hydraulic system is not particularly limited in this embodiment, and in some specific embodiments, as in the embodiment of fig. 2, the data of the hydraulic system may be acquired through a terminal connected to an electronic device. The data of the hydraulic system are obtained by converting data generated by a sensor of the hydraulic system and a controller of the hydraulic system by a terminal.

In this embodiment, the specific implementation manner in which the terminal obtains the data generated by the sensor and the controller of the hydraulic system and converts the data is not limited, for example:

the terminal obtains data generated by a plurality of sensors of the hydraulic system and data generated by the controller through the data acquisition unit, the terminal carries out signal filtering on the data, and the data generated by each sensor is converted (unit conversion, parameter calculation and the like) according to a corresponding conversion mode according to a preset corresponding relation between the sensors and the conversion mode to obtain the data acquired by the sensors; according to the corresponding relation between the preset controller data type and the conversion mode, converting the data generated by the controller according to the corresponding conversion mode (unit conversion, parameter calculation and the like) to obtain the control information of the hydraulic system. The data acquisition unit CAN be any one or more of an ADC unit, an IO unit, an Ethernet unit and a CAN bus unit, and each unit CAN be one or more paths.

According to the embodiment, the data of the hydraulic system is acquired through the terminal connected with the electronic equipment, so that the electronic equipment can be arranged at any position convenient to set, the monitoring process is convenient to manage, and the remote monitoring of the hydraulic system is realized.

In other embodiments, the electronics may also directly acquire data from the hydraulic system.

Step 302: and arranging the first target data based on the acquisition time of the first target data to obtain target sequence data.

As described above, the performance of the hydraulic system can be characterized by the change in the data collected by the sensor corresponding to the element under the control information of the hydraulic system for a period of time. The first target data is only the data collected by the sensor and the control information in the period of time, and the change condition of the data along with time needs to be obtained.

According to the embodiment, the first target data are arranged based on the acquisition time of the first target data, so that the target sequence data reflecting the change of the data acquired by the sensors corresponding to the elements under the control information of the hydraulic system within the period of time is obtained.

Taking first target data as data acquired in a target time period and acquired by a sensor corresponding to an execution element, and taking control information of a hydraulic system acquired in the target time period as an example:

50 data acquired by the pressure sensor corresponding to the execution element are acquired in the target duration, and the data are recorded as follows: pressure data 1 acquired at the first moment, pressure data 2 acquired at the second moment, pressure data 3, … … acquired at the third moment and pressure data 50 acquired at the fifty-th moment;

and acquiring 50 data acquired by the flow sensor corresponding to the execution element, and recording the 50 data as follows: flow data 1 acquired at a first moment, flow data 2 acquired at a second moment, flow data 3, … … acquired at a third moment, and flow data 50 acquired at a fifty-th moment;

and acquiring 50 data acquired by the displacement sensor corresponding to the execution element, and recording the 50 data as follows: the displacement data 1 acquired at the first moment, the displacement data 2 acquired at the second moment, the displacement data 3, … … acquired at the third moment and the displacement data 50 acquired at the fifty moment;

and 50 pieces of control information are also acquired, and the control information is recorded as follows according to the sequence of the acquisition time: control information 1 acquired at the first time, control information 2 acquired at the second time, control information 3, … … acquired at the third time, and control information 50 acquired at the fifty-th time.

Taking the pressure data 1, the flow data 1, the displacement data 1 and the control information 1 acquired at the first moment as a first group of data; taking the pressure data 2, the flow data 2, the displacement data 2 and the control information 2 acquired at the second moment as a second group of data; taking the pressure data 3, the flow data 3, the displacement data 3 and the control information 3 acquired at the third moment as a third group of data; … … the pressure data 50, the flow rate data 50, the displacement data 50, and the control information 50 acquired at the fifty-th time are taken as the fifty-th set of data.

The fifty groups of data are arranged according to the acquisition time to obtain target sequence data: a first set of data, a second set of data, a third set of data, … …, and a fifty-th set of data.

The above manner of obtaining the target sequence data is merely illustrative, and the present embodiment may also use other manners to arrange the first target data to obtain the target sequence data.

In addition, when the first target data includes data acquired in the target duration and acquired through sensors corresponding to a plurality of elements, and control information of the hydraulic system acquired in the target duration, a manner of acquiring the target sequence data is similar to the above manner, and will not be repeated here.

Step 303: and inputting the target sequence data and the environmental information in the target duration into a first target model to obtain evaluation information representing the performance of the hydraulic system.

The environmental information includes environmental temperature and/or hydraulic system cleaning information. The ambient temperature is, for example, the ambient temperature of the location of the hydraulic system, and the hydraulic system cleanliness information is the cleanliness of the hydraulic system's pressurized oil.

The change of the data collected by the sensor under the control information is affected by the performance of the hydraulic system and the environmental information (such as the environmental temperature of the position of the hydraulic system, the cleanliness of the pressure oil of the hydraulic system and other factors) of the period of time. That is, the target sequence data is not necessarily the same even if the performance of the hydraulic system is unchanged under different environmental information. Therefore, the evaluation information that accurately characterizes the performance of the hydraulic system cannot be determined from the target sequence data.

According to the embodiment, the interference of the environmental information can be reduced by comprehensively considering the target sequence data and the environmental information, and the result of accurately representing the performance of the hydraulic system is obtained. And the target sequence data and the environmental information in the target duration are input into the first target model, so that evaluation information which accurately characterizes the performance of the hydraulic system is obtained.

In this embodiment, the manner of obtaining the first object model is not limited, for example:

the first sample data is selected from the sample data of the hydraulic system, and the manner of selecting the first target data may be referred to above, which will not be described herein again;

the first sample data is ordered based on the time of obtaining the first sample data to obtain the sample sequence data, and the above method for obtaining the target sequence data can be referred to, which is not described herein.

And training the first initial model by taking sample sequence data, corresponding sample environment information and sample performance evaluation information as input of the first initial model, taking a predicted result as output and taking similarity between the sample performance evaluation information and the predicted result as an optimization condition to obtain the first target model. The sample performance evaluation information is evaluation information corresponding to the actual performance of the hydraulic system when the first sample data is acquired.

The above is only one possible way to obtain the first object model, and the present embodiment may also use other ways to obtain the first object model.

According to the scheme, the data acquired in the target time period and acquired through the sensors corresponding to the elements of the hydraulic system are selected, and the control information of the hydraulic system acquired in the target time period is used as first target data; arranging the first target data according to the acquisition time of the first target data to obtain target sequence data, wherein the target sequence data can reflect the performance of the hydraulic system; the target sequence data is affected by the performance of the hydraulic system and also is affected by the environmental information, the interference of the environmental information can be reduced by inputting the target sequence data and the environmental information in the target time length into the first target model, and the evaluation information for accurately representing the performance of the hydraulic system is obtained, so that the hydraulic system is maintained in time when the performance of the hydraulic system is poor, and the occurrence of faults of the hydraulic system is reduced.

In some alternative embodiments, the method may further include, after step 303:

and notifying the evaluation information through a preset notification mode.

In this embodiment, the preset notification manner is not specifically limited, for example:

1) The electronic equipment is provided with a display screen, and the evaluation information is displayed through the display screen;

2) And responding to the evaluation information acquisition request sent by the user terminal, and sending evaluation information corresponding to the evaluation information request to the user terminal.

The foregoing is two possible preset notification manners, and other notification manners may be preset in this embodiment, and the evaluation information may be notified by other notification manners.

In some specific embodiments, the obtained evaluation information corresponding to the continuous target durations may be displayed in a list, a curve, a 2D/3D model, and the like, so that a preset person knows a performance change trend of the hydraulic system, and more effective measures are adopted to maintain the hydraulic system.

In this embodiment, the data of the hydraulic system may also be notified by the notification method, which is not described herein.

According to the embodiment, after the evaluation information is obtained, the evaluation information is notified through the preset notification mode, so that a preset person can know the performance of the hydraulic system, the hydraulic system is maintained in time when the performance of the hydraulic system is poor, and the occurrence of faults of the hydraulic system is reduced.

In some specific embodiments, in order to improve the security of the notification process and avoid the electronic device from being attacked, before the user terminal and the electronic device establish a connection or the electronic device displays information, the user login information is verified, and only after the verification is passed, the electronic device notifies the evaluation information in a preset notification mode. In addition, the electronic device can determine the operation authority corresponding to the user login information according to the corresponding relation between the preset login information and the operation authority, so as to determine which information can be notified in a preset notification mode, namely, which information can be queried by the user.

In some specific embodiments, after the data of the hydraulic system is acquired, the data corresponding to different elements may be classified according to the element types, and the data corresponding to the same elements may be stored according to the sequence of the receiving times, so as to conveniently and quickly select the first target data later.

step 401: for any element of the hydraulic system, selecting data acquired at the same time and acquired through a sensor corresponding to the element from the data of the hydraulic system as second target data of the element.

As described above, the data collected by the sensor may be subject to a hidden malfunction of the hydraulic system even if the data does not exceed the preset value corresponding to the sensor. In this embodiment, by comprehensively considering the data acquired by the sensor corresponding to a certain element at the same time, some hidden faults of the element of the hydraulic system can be determined. For example:

the executive component corresponds to a pressure sensor, a flow sensor and a displacement sensor. At the target moment, the data collected by the pressure sensor does not exceed the corresponding pressure threshold, the data collected by the flow sensor does not exceed the corresponding flow threshold, and the data collected by the displacement sensor does not exceed the corresponding displacement threshold. If the data collected by the sensor is only compared with the preset value corresponding to the sensor, the fact that the executing element fails at the target moment is judged. In this embodiment, the data collected by the pressure sensor and the data collected by the flow sensor are comprehensively considered, and the data collected by the displacement sensor can monitor faults which cannot be judged by a single parameter.

Step 402: and inputting the second target data of the element into a second target model corresponding to the element to obtain information representing whether the element works beyond limit.

In this embodiment, the second target data of the element is input into the second target model corresponding to the element, so that information (whether the element fails) indicating whether the element is out of limit or not at the above time is conveniently and accurately obtained. Also take the above-mentioned actuator as an example:

and inputting the data acquired by the pressure sensor and the data acquired by the flow sensor into a second target model corresponding to the executive component, and outputting yes or no, wherein yes represents that the executive component works beyond limit, and no represents that the executive component does not work beyond limit.

The above-described embodiments are merely illustrative of possible implementations of the second target data and the information characterizing whether the element is out of operation, and the present embodiment is not particularly limited thereto.

In this embodiment, the manner of obtaining the second object model is not limited, for example:

for any element, taking sample data acquired by a sensor corresponding to the element at the same moment and a real judging result of whether the element is faulty at the moment as input of a second initial model, taking a predicted result as output, taking similarity between the real judging result and the predicted result as an optimization condition, and training the second initial model to obtain a second target model corresponding to the element.

The above is only one possible way to obtain the second target model, and the embodiment may also use other ways to obtain the second target model.

The embodiment of fig. 4 may be implemented alone or in combination with the embodiment of fig. 3 described above, and this embodiment is not particularly limited.

step 501: for any element of the hydraulic system, selecting data acquired in the target duration and acquired through a sensor corresponding to the element from the data of the hydraulic system, and the control information as first target data of the element.

In some scenarios, it is desirable to determine the performance of components of the hydraulic system in order to more specifically maintain the hydraulic system. According to the embodiment, the data acquired through the sensor corresponding to a certain element and the control information are acquired in the target time period, so that the change of the data acquired through the sensor corresponding to the element under the control information in the time period can be obtained, and the change can characterize the performance of the element.

The manner in which the first target data of any element is selected from the data of the hydraulic system may refer to the implementation of step 301, and will not be described herein.

Step 502: and arranging the first target data based on the acquisition time of the first target data to obtain target sequence data.

Step 503: and inputting target sequence data of any element of the hydraulic system and the environmental information into a first target model corresponding to the element to obtain evaluation information representing the performance of the element.

In this embodiment, different elements correspond to different sensors; when the performances of different elements are normal, the change of the data collected by the sensors corresponding to the different elements under the control information is also different. Thus, no evaluation information of the performance of the individual elements can be obtained by only one first object model. Based on this, each element in this embodiment has a corresponding first object model.

for any element, the first sample data of the element may be selected by referring to the above manner of selecting the first target data, which is not described herein;

the first sample data is ordered based on the time of obtaining the first sample data of the element, so as to obtain the sample sequence data of the element, and the method for obtaining the target sequence data can be referred to, which is not described herein.

The sample performance evaluation information of the element is evaluation information corresponding to the real performance of the element when the first sample data of the element is acquired.

step 601: and selecting data acquired in the target time period and acquired through sensors corresponding to elements of the hydraulic system from the data of the hydraulic system, and the control information as first target data of the hydraulic system.

In some situations, the overall performance of the hydraulic system needs to be determined, only data acquired through a sensor corresponding to a certain element or a part of elements of the hydraulic system within a target duration is selected as first target data, and evaluation information representing the overall performance of the hydraulic system cannot be comprehensively and accurately determined according to the first target data. According to the embodiment, the data acquired through the sensors corresponding to the elements and acquired in the target time period and the control information are selected, so that the change of the data acquired through the sensors corresponding to the elements under the control information in the time period can be obtained, and the change can represent the overall performance of the hydraulic system.

The manner in which the first target data of each element is selected from the data of the hydraulic system may refer to step 301 described above, and will not be described again here.

Step 602: and arranging the first target data based on the acquisition time of the first target data to obtain target sequence data.

This step 602 is the same as the implementation of step 302 described above, and will not be described here again.

Step 603: and inputting the target sequence data and the environmental information of the hydraulic system into a first target model corresponding to the hydraulic system to obtain evaluation information representing the overall performance of the hydraulic system.

As described above, different data may be selected as the first target data, and it is difficult to accurately obtain evaluation information characterizing the performance of the hydraulic system from different angles only by one first target model. Based on this, the present embodiment presets a plurality of first object models. The first target data obtained in the mode corresponds to a first target model corresponding to the hydraulic system.

the first sample data of the hydraulic system may be selected by referring to the above manner of selecting the first target data, which is not described herein again;

the first sample data is ordered based on the acquisition time of the first sample data of the hydraulic system to obtain the sample sequence data of the hydraulic system, and the method for obtaining the target sequence data can be referred to, which is not described herein.

The sample performance evaluation information of the hydraulic system is evaluation information corresponding to the actual overall performance of the hydraulic system when the first sample data is acquired.

The implementation manner of this step 701 may refer to the manner in which the terminal obtains the data of the hydraulic system in step 301, which is not described herein.

Step 702: and sending the data of the hydraulic system to electronic equipment connected with the terminal.

In this embodiment, the terminal is disposed at a position closer to the hydraulic system, and the electronic device is disposed at a position farther from the hydraulic system. When some obvious faults occur in the hydraulic system, an alarm needs to be triggered timely. Based on the above, in this embodiment, the data generated by each sensor is converted by the terminal to obtain the data of the hydraulic system (i.e. the data collected by each sensor) and the corresponding preset threshold value are compared, if the data collected by a certain sensor reaches the preset threshold value corresponding to the sensor, it is indicated that the hydraulic system has a relatively obvious fault, and an alarm is given by a preset alarm mode.

The alarm can be realized by the following modes through a preset alarm mode:

1) The terminal is provided with a loudspeaker, and a preset voice is sent through the loudspeaker;

2) The terminal sends alarm information to the connected alarm equipment, and the alarm equipment responds to the received alarm information to alarm.

The foregoing is two possible preset alarm modes, and the embodiment can also alarm through other alarm modes.
