Specifically, when the fault signal is generated when the electric energy conversion efficiency is abnormal, the corresponding second operation data is the electric energy conversion efficiency; when the fault signal is generated when the hydrogen conversion amount is abnormal, the corresponding second operation data is the hydrogen conversion amount; the second operation data is monitored in real time by the corresponding sensor and is uploaded to the electronic equipment. Standard second operation data is empirically set by a technician and is input into the electronic device in advance, and the second operation data difference value=. The degree of abnormality of the SOFC is greater as the difference in the second operation data increases.

The corresponding relation between the amplitude change frequency and the first sub-time attribute value, and the corresponding relation between the amplitude change value and the second sub-time attribute value are all set by a technician according to working experience and are input into the electronic equipment in advance. The amplitude change value is determined based on the amplitude corresponding to the current moment and the preset amplitude, and the preset amplitude is not limited in the embodiment of the application.
Step S105, determining fault information of the battery in a preset operation state based on the second operation data, all the related first operation data and the corresponding time sequence attribute values, wherein the fault information comprises: there is a fault or no fault.
In particular, the specific implementation of determining fault information from the second operational data, the associated first operational data and the timing attribute value may be referred to the following embodiments. It can be understood that in the process of determining the fault information, the related first operation data is taken as a reference, and the fault information of the battery in the preset operation state is determined by combining the time sequence attribute value related to the first operation data, so that the accuracy of determining the fault information is effectively improved.
In the embodiment of the application, when the fault signal is detected, a plurality of corresponding first operation data are directly determined according to the fault signal so as to be judged together with the first operation data; acquiring second operation data corresponding to the fault signal, and determining second operation data difference values, wherein different second operation data difference values correspond to batteries with different abnormal degrees, and the batteries with different abnormal degrees may correspond to different first operation data, so that associated first operation data are determined according to the second operation data difference values and all the first operation data, and the accuracy of the associated first operation data is effectively improved; acquiring time sequence attribute values corresponding to all the associated first operation data respectively so as to determine the change condition of the associated first operation data; determining fault information of the battery in a preset state by combining the related first operation data and the change condition of the related first operation data; compared with the prior art that the battery fault information is determined only according to a certain item of data, the application combines the running state of the battery, the related first running data under the running state, the change condition of the related first running data and the like to achieve the purpose of determining the battery fault information, so that the technical effect of determining the battery fault information accuracy is effectively improved, and the technical problem of poor battery fault information accuracy in the prior art is solved.
As shown in fig. 2, a possible implementation manner of the embodiment of the present application is a flowchart of a method for determining battery fault information provided by the embodiment of the present application, step S105 determines fault information of a battery in a preset operation state based on second operation data, all associated first operation data and respective corresponding time sequence attribute values, and includes steps S1051-S1054:
Step S1051: acquiring environment information, and determining initial associated first operation data according to the environment information and time sequence attribute values corresponding to all the associated first operation data;
Step S1052: determining first components corresponding to the second operation data based on the second operation data, and determining respective second components based on all initial associated first operation data;
step S1053: determining a plurality of target associated first operation data based on the first assembly, all initial associated first operation data and the corresponding second assemblies;
Step S1054: and acquiring first historical data corresponding to each of the first operation data associated with all the targets, and determining fault information of the battery in a preset operation state according to all the first historical data.
Specifically, the environmental information includes: ambient temperature data or humidity data may be monitored by corresponding sensors and uploaded to the electronic device. The specific process of determining the initial association first operational data according to the environmental information and the time sequence attribute value comprises the following steps: judging whether the change environment data exists, if so, acquiring a change period corresponding to the change environment data, acquiring associated first operation data without data change in the change period, and determining the associated first operation data without data change as initial associated first operation data. It will be appreciated that during operation of the battery, an excessively high ambient temperature, an excessively low ambient temperature, an excessively high humidity or an excessively low humidity may affect the initial associated first operation data, i.e. there is a change in a part of the associated first operation data due to an environmental factor rather than a fault factor, and determining the fault information of the battery according to the above-mentioned associated first operation data that changes due to the environmental factor may result in determining erroneous fault information, so that the associated first operation data that is not changed due to the environmental factor, i.e. the self-fault factor, is determined as the initial associated first operation data. The first component may be determined according to the first correspondence and the second component may be determined according to the second correspondence; the first corresponding relation is the corresponding relation between the second operation data and the first component, and the second corresponding relation is the corresponding relation of the first operation data and the second component which are initially associated. The first corresponding relation and the second corresponding relation are determined by a technician according to a plurality of historical data, wherein the establishing process of the first corresponding relation comprises the following steps: acquiring a plurality of historical second operation data in the same operation state as the preset operation state, matching the second operation data with the plurality of historical second operation data to determine target historical second operation data, acquiring historical first components corresponding to all the target historical second operation data, determining third occurrence frequencies corresponding to all the historical first components, and taking the historical first component with the highest third occurrence frequency as the first component of the second operation data. The process of establishing the second corresponding relationship is the same as the process of establishing the first corresponding relationship, and the embodiment of the application is not repeated, and the first component and the second component are respectively corresponding component names. For a specific implementation of determining the target associated first operational data from the first component, the initial associated first operational data and the second component, reference may be made to the following embodiments. The first history data may be obtained from a preset history database, where the first history data includes: the method comprises the steps of determining an abnormal interval period according to historical abnormal frequency and corresponding abnormal period, comparing the abnormal interval period with a preset abnormal interval period to determine the quantity of target associated first operation data of which the abnormal interval period is smaller than the preset abnormal interval period, and determining that fault information of a battery is fault if the quantity is larger than a preset quantity threshold; otherwise, determining that no fault exists, and limiting the preset abnormal interval period and the preset quantity threshold value according to the embodiment of the application. It will be appreciated that when the target-associated first operational data is frequently abnormal, the SOFC has a high probability of abnormality and is therefore determined to be faulty at this time. And the historical abnormal frequency represents the frequency corresponding to the first operation data associated with the target when the first operation data is not the standard value.
In the embodiment of the application, environment information is acquired, and initial associated first operation data is determined according to the environment information and a time sequence attribute value, so that the associated first operation data which is not influenced by environmental factors is taken as a reference; determining a first component of second operation data and a second component of initial association first operation data, and determining target association first operation data according to the first component, the initial association first operation data and the second component; and then acquiring the first historical data corresponding to the target associated first operation data, and taking the first historical data as a reference to effectively improve the accuracy of determining the fault information.
In one possible implementation manner of the embodiment of the present application, step S105 determines, based on the first component, all the initial associated first operation data and the respective corresponding second components, a plurality of target associated first operation data, including:
acquiring first position and first function information of a first component, and acquiring second positions and second function information corresponding to all second components;
determining, for each second component, an association value according to the first location, the first function information, the second location, and the second function information;
And determining a plurality of targets to be associated with the first operation data based on all the initial associated first operation data, the corresponding associated values and the preset associated value threshold, wherein the associated value of the targets to be associated with the first operation data is larger than the preset associated value threshold.
Specifically, the first location, the second location, the first function information, and the second function information may be acquired from a location information base and a function information base, respectively. For a specific implementation of determining the association value according to the first location, the first function, the second location and the second function information, reference may be made to the following embodiments. It can be appreciated that the closer the location between the components, the higher the degree of association between the second operational data and the initially associated first operational data, and the higher the degree of association between the first function and the second function, the higher the degree of association between the second operational data and the initially associated first operational data, and thus the association value is determined from the location dimension and the function dimension, so as to effectively improve the accuracy of the association value determination. The preset association value threshold is set by a technician according to working experience and is input into the electronic equipment in advance. And comparing the association value with a preset association value threshold value, further determining a target association value larger than the preset association value threshold value, and determining initial association first operation data corresponding to the target association value as target association first operation data. It can be understood that the association degree of the initial association first operation data and the second operation data corresponding to the target association value is higher, at this time, the initial association first operation data with the higher association degree is taken as a reference, and the fault information is determined, so that the accuracy of determining the fault information can be effectively improved.
In the embodiment of the application, the first position, the first function information, the second position and the second function information are acquired, the association value is determined, and then the target association first operation data is determined according to the association value, the initial association first operation data and the preset association value threshold value, so that the target association first operation data with higher association degree with the second operation data is used for effectively improving the accuracy of determining the target association first operation data.
In one possible implementation manner of the embodiment of the present application, step S105 determines an association value according to the first location, the first function information, the second location and the second function information, including:
Determining a structural association value based on the first location and the second location;
Determining a function association value based on the first function information and the second function information;
Acquiring a first weight value corresponding to the structural association value and a second weight value corresponding to the functional association value;
the association value is determined based on the structural association value, the first weight value, the functional association value, and the second weight value.
Specifically, a position difference value is determined according to a first position and a second position, a structure association value corresponding to the position difference value is determined according to a corresponding relation between the position difference value and the structure association value, the corresponding relation between the position difference value and the structure association value is set by a technician according to working experience, and in the corresponding relation, the structure association value is increased along with the decrease of the position difference value. The specific process of determining the function association value according to the first function information and the second function information comprises the following steps: and acquiring a plurality of preset second functions of the first function information, and matching the second functions with the plurality of preset second functions to determine a target second function, namely a second function with an association relation with the first function. Acquiring the number of the second functions, and determining a function association value according to the corresponding relation between the number and the function association value; with the increase of the number of the second functions, the function association value is increased, and the method and the device do not limit the establishment process of the corresponding relation between the number and the function association value, so that the user can set the device and the method. The first weight value and the second weight value may be set by a technician according to working experience, and the embodiment of the present application is not limited. It can be understood that in the SOFC operation process, the operation data with the structural association relationship and the operation data with the functional association relationship have different effects on the SOFC, so that the first weight value and the second weight value need to be acquired to perform targeted calculation. The correlation value can be determined according to a calculation formula of the correlation value, wherein the calculation formula is as follows: association value = structure association value x first weight value + function association value x second weight value.
In the embodiment of the application, the structural association value is determined according to the first position and the second position to determine the association value from the structural dimension, and the functional association value is determined according to the first functional information and the second functional information to determine the association value from the functional dimension.
In one possible implementation manner of the embodiment of the present application, step S103 determines, based on the second operation data difference value and all the first operation data, a plurality of associated first operation data from all the first operation data, including:
Obtaining second historical data of a second operation data difference value, wherein the second historical data comprises: historical first operational data and first frequency of occurrence;
Determining target historical first operation data from all the historical first operation data based on a preset minimum occurrence frequency and a first occurrence frequency, wherein the first occurrence frequency of the target historical first operation data is not greater than the preset minimum occurrence frequency;
and matching all the first operation data with the target historical first operation data, and determining initial first operation data, wherein the initial first operation data represents the same data as the target historical first operation data.
Specifically, second historical data for the second operational data difference may be obtained from a historical database. The preset minimum occurrence frequency is set by a technician according to working experience, in the embodiment of the application, the preset minimum occurrence frequency is preferably 1, and then the first occurrence frequency of the historical first operation data is compared with the preset minimum occurrence frequency to determine the target historical first operation data. It is understood that when the first occurrence frequency of any one of the historical first operation data is not greater than the preset minimum occurrence frequency, it indicates that the occurrence of the historical first operation data may be accidental, and thus the historical first operation data greater than the preset minimum occurrence frequency is determined as the target historical first operation data. And determining initial first operation data through a matching algorithm, wherein the embodiment of the application does not limit the specific implementation process of the initial first operation data, and the user can set the initial first operation data by himself.
