Based on this, referring to fig. 1, fig. 1 is a flowchart of an anomaly analysis method of a sensor signal calibration control system according to an embodiment of the present invention, where the method is applied to an artificial intelligence analysis system, and further may include S101-S106.
S101, an artificial intelligent analysis system acquires a calibration control system operation log to be subjected to anomaly analysis.
The calibration control system operation log to be subjected to anomaly analysis comprises X sensor signal calibration processing reports, wherein X is a positive integer.
In some examples, the calibration control system log to be subjected to anomaly analysis may be understood as a log of the operation of the sensor signal calibration control system when performing calibration control on the corresponding sensor signal.
Further, the sensor includes various types such as a resistive sensor, an inductive sensor, a capacitive sensor, a piezoelectric sensor, a magneto-electric sensor, a thermo-electric sensor, a photoelectric sensor, a digital sensor, an optical fiber sensor, an ultrasonic sensor, a thermal sensor, an analog sensor, and the like. The calibration control system for the sensor signals acquired by the different types of sensors can be selected adaptively as well, which is not shown here. Still further, the sensor signal calibration process report may be understood as a calibration process record in text form.
S102, acquiring calibration task text description vectors of the X sensor signal calibration processing reports and calibration link text description vectors of the X sensor signal calibration processing reports, and acquiring calibration result feedback information of a calibration control system operation log to be subjected to anomaly analysis.
In the embodiment of the invention, the calibration task text description vector and the calibration link text description vector are respectively used for representing the global report text characteristic and the local report text characteristic of the corresponding sensor signal calibration processing report. When the calibration control processing is performed on the sensor signal, the sensor signal calibration control system usually performs corresponding calibration task link splitting processing according to a complete calibration control task, and then performs orderly calibration control based on the split calibration task links so as to realize the processing of the sensor signal. Thus, the calibration task text description vector and the calibration link text description vector can reflect the characteristics of the sensor signal calibration process report from different granularities. As another example, the sensor signal calibration process report may include a record in text form of the initial sensor signal, calibration control parameters, calibration signals, etc.,
Further, the calibration result feedback information of the calibration control system operation log to be subjected to anomaly analysis can be understood as: after the calibration signal corresponding to the calibration control system operation log to be subjected to anomaly analysis is returned to the request end, the request end performs opinion feedback after use according to the calibration signal, and the opinion feedback can represent the signal calibration quality of the sensor signal calibration control system corresponding to the calibration control system operation log to be subjected to anomaly analysis.
S103, performing calibration task description comparison on the calibration task text description vectors of the X sensor signal calibration processing reports and the prior calibration task text description vectors corresponding to the prior calibration control system operation logs to obtain calibration task description comparison information.
And S104, performing calibration link description comparison on the calibration link text description vectors of the X sensor signal calibration processing reports and the prior calibration link text description vectors corresponding to the prior calibration control system operation logs to obtain calibration link description comparison information.
S105, performing calibration feedback comparison on the calibration result feedback information of the calibration control system operation log to be subjected to anomaly analysis and the prior calibration result feedback information of the plurality of prior calibration control system operation logs to obtain calibration feedback comparison information.
For S103-S105, the a priori calibration control system operation log may be a calibration control system operation log used as a reference for anomaly analysis, for example, an authenticated calibration control system operation log, or for example, a historical calibration control system operation log. Based on the above, the prior calibration task text description vector, the prior calibration link text description vector and the prior calibration result feedback information can also be respectively used as references of the calibration task text description vector, the calibration link text description vector and the calibration result feedback information.
S106, determining an abnormality judgment view of the calibration control system operation log to be subjected to abnormality analysis according to the calibration task description comparison information, the calibration link description comparison information and the calibration feedback comparison information.
In the embodiment of the invention, the calibration task description comparison, the calibration link description comparison and the calibration feedback comparison described in S103-S105 are three different steps for carrying out the abnormality analysis, and the feature dimensions concerned by the three different steps are different, so that the abnormality analysis of the operation log of the calibration control system can be comprehensively and comprehensively realized as much as possible, and whether the abnormality/fault exists in the sensor signal calibration control system or not is judged.
In S106, the anomaly discrimination viewpoint is used to characterize whether the calibration control system operation log to be subjected to anomaly analysis is an anomaly operation log. In the embodiment of the invention, the abnormal operation log can reflect the abnormality/fault of the sensor signal calibration control system corresponding to the operation log of the calibration control system to be subjected to abnormality analysis, and the abnormal point/fault point, such as hardware structure fault abnormality or software system fault abnormality, can be further determined through the dissimilarity of the calibration task description comparison, the calibration link description comparison and the calibration feedback comparison.
It can be seen that, through S101-S106, by acquiring a plurality of sensor signal calibration processing reports of the calibration control system operation log to be subjected to anomaly analysis, calibration task text description vector mining, calibration link text description vector mining, and calibration result feedback information mining can be performed for each sensor signal calibration processing report, so that when the operation log is compared and analyzed, it can be implemented according to three types of information mined, and according to comparison information corresponding to the three types of information, whether the calibration control system operation log to be subjected to anomaly analysis is an anomaly operation log is determined, and in view of implementing anomaly analysis through the three types of information of the operation log, whether the calibration control system operation log to be subjected to anomaly analysis is an anomaly operation log can be determined based on as many description levels, thereby improving anomaly analysis accuracy and reliability of the calibration control system for sensor signals based on the anomaly analysis concept of the operation log.

On this basis, the calibration task text description vector of the calibration processing report of the X sensor signals in S103 is compared with the prior calibration task text description vectors corresponding to the operation logs of the multiple prior calibration control systems to obtain calibration task description comparison information, including S1031-S1033.
