All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application described herein may be used. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
According to an embodiment of the present invention, there is provided a data processing method for oil level abnormality monitoring, as shown in fig. 1, the method including steps S101 to S104 as follows:
step S101, collecting mechanical state information and an oil level data set, wherein the oil level data set comprises an oil level value and sampling time.
In specific implementation, the mechanical state information may be collected through an acceleration sensor, the oil level data may be collected through a pressure sensor in the oil tank, the above-mentioned collection process may be performed according to a certain time interval, the time interval may be an equal time interval or an unequal time interval, and a person skilled in the art can flexibly set the specific sampling interval according to actual conditions, and is not specifically limited herein. The plurality of oil level data sampled at regular time intervals form an oil level data set, which includes specific oil level values and corresponding sampling times.
And step S102, determining an oil level change slope according to the oil level data group to obtain an oil level change sequence.
In specific implementation, the oil level change slope k may be determined according to the oil level value X2 obtained by the current sampling and the corresponding sampling time T2, and the oil level value X1 obtained by the last sampling and the corresponding sampling time T1, and specifically calculated according to the following formula:
Figure BDA0002368640100000061
because a plurality of oil level data are obtained by continuous sampling and the like at certain time intervals, a plurality of oil level change slopes can be correspondingly obtained, and an oil level change sequence can be obtained by comparing each of the plurality of oil level change slopes with a preset oil level characteristic change threshold value.
And step S103, extracting oil level change characteristics according to the oil level change sequence.
In specific implementation, the oil level change sequence reflects the relationship between the oil level change slope and a preset threshold value in a period of time, if the oil level change slope exceeds the preset threshold value, it indicates that the oil level may be abnormal, and if the oil level decrease slope does not exceed the preset threshold value, it indicates that the oil level may not be abnormal, so that the oil level change characteristics can be extracted according to the oil level change sequence as one of the conditions for monitoring and determining whether the oil level is abnormal.
And step S104, monitoring whether oil level abnormity occurs according to the oil level change characteristics and the mechanical state information.
In particular, the abnormality determination conditions of the machine in different states should be different, so after the oil level variation characteristic is obtained, it is necessary to combine the oil level variation characteristic with the current state information of the machine to determine whether the oil level is abnormal. For example, the oil level variation threshold for a machine in motion is clearly different from the oil level variation threshold for a machine in rest. Through the process, the accuracy and the timeliness of oil level monitoring are realized, and especially when the oil level monitoring system is applied to oil tank oil quantity management of mechanical vehicles under different working conditions, the occurrence of oil level abnormal conditions such as oil stealing and oil leakage can be effectively monitored.

Therefore, the embodiment of the application firstly needs to determine the sampling number of the oil level change slope and the oil level change threshold according to the current state information of the machine. When an oil level change sequence is determined, N oil level change slopes stored within a period of time need to be sorted according to the generation time of the slopes, an oil level change slope queue formed by the N oil level change slopes is dynamically changed in real time, and when a new k value is generated, the earliest k value is deleted and shifted.

The sizes of the preset oil level abrupt change threshold H1 and the preset oil level gradual change threshold H2 can be flexibly set by those skilled in the art according to actual situations, and are not particularly limited herein. Specifically, the oil level mutation sequence F1~FNCan be determined according to the following formula:
a) if k isi>H1, then Fi=1
b) If k isi>H1/2, then Fi=0.5
c) If k isi<-H1, then Fi=-1
d) If k isi<H1/2, then Fi=-0.5,
Wherein k isiRepresents k1~KN(ii) any one of oil level change slopes, FiRepresents and kiMutation of sequence F at oil level1~FNThe value of (1).
Oil level slowly-varying sequence D1~DNCan be determined according to the following formula:
a) if k isi>H2, then Di=1
b) If k isi>H2/2, then Di=0.5
c) If k isi<-H2, then Di=-1
d) If k isi<H2/2, then Di=-0.5,
Wherein k isiRepresents k1~KNAny one of the oil level change slopes, DiRepresents and kiIn the oil level slowly changing sequence D1~DNThe value of (1).
Step S203, determining the oil level change characteristic according to the oil level abrupt change sequence, the oil level gradual change sequence and the sampling number N of the oil level change slope.

Gi=Di+Fix N, wherein i is more than or equal to 1 and less than or equal to N.
Step S302, according to the mechanical state information, carrying out weighted summation processing on the oil level rising characteristic and/or oil level slow-falling characteristic judgment sequence.

alternatively, when the oil level variation characteristic does not belong to any one of the oil level raising characteristic, the oil level slow-falling characteristic, and the oil level sudden-falling characteristic, it is determined that there is no variation characteristic in the oil level.
As a preferred implementation manner of the embodiment of the present application, as shown in fig. 5, the acquiring oil level data set includes the following steps S501 to S502:
in step S501, it is determined whether an oil level abnormality monitoring instruction is received.
In specific implementation, before collecting oil level data, the method further comprises a step of acquiring a motion state of the machine, specifically, a continuous time domain signal of triaxial acceleration data of the machine can be collected through a triaxial sensor, the collected continuous time domain signal is divided according to time periods, and then one or more time domain signal segments are obtained, so that the current state of the machine, including a working state or a static state, is judged according to at least one time domain signal segment.
