Embodiment Construction
[0072] A turnout is an essential line device when a train transfers from one track to or crosses another track. Usually, the normal process of a turnout action can include an unlocking process, a switching process, and a locking process. The current of the switch action is generally divided into A-phase current, B-phase current and C-phase current. The current value change of normal turnout action is divided into three stages according to its process, which are unlocking stage, conversion stage and communication expression stage. Such as Figure 1a As shown, in the unlocking stage, the switch machine needs a large starting current to complete the internal unlocking, and at the same time drive the external locking device to unlock the switch; in the switching stage, since there is no large resistance in the switching process, the three-phase current maintains a stable state. In the stage of communication and representation, the control circuit of the switch is cut off, and at t...

The present invention relates to a fault diagnosis method, device, equipment and storage medium. The terminal obtains the characteristic information corresponding to the switch action current data, and according to the first category label corresponding to the marked switch action current data and the marked switch action current data. The feature information is obtained to obtain the classification model, and at the same time, according to the classification model, the unmarked switch operation current data and the feature information of the unmarked switch operation current data are processed to obtain the fault diagnosis result of the switch operation. In this application, the terminal obtains the classification model according to the first category label and the characteristic information of the marked switch operation current data, and then processes the unmarked switch operation current data and its characteristic information according to the classification model to obtain the fault diagnosis result of the switch operation Therefore, the terminal can obtain the fault diagnosis result of the switch operation without obtaining the label of the current data of each switch operation, which improves the efficiency of the fault diagnosis of the switch operation.
Description
technical field [0001] The present invention relates to the technical field of algorithms, in particular to a fault diagnosis method, device, equipment and storage medium. Background technique [0002] Turnout is an essential line equipment when a train transfers from one track to or crosses another track. It is an important part of the railway track and is also the equipment with the highest failure rate. Once the switch breaks down and cannot complete the prescribed action, it will cause serious accidents. [0003] At present, in order to prevent accidents, railway departments use predictive models based on machine learning algorithms to diagnose turnout faults. Professionals check the electrical characteristic curve of the turnout every day, and identify the fault of the turnout by comparing it with the monitoring data of the turnout in normal operation. [0004] This way of fault diagnosis of switch operation requires a lot of manpower and material resources, and it is...
