[0057] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0058] Figure 1It is a flowchart of a method for comparing the consistency of multi-source signal status data provided by an embodiment of the present invention. In one embodiment, it specifically includes the following steps:

[0059] S101: Obtain the original multi-source signal status data.

[0060] Use optical fiber communication technology to obtain multi-source signal status data from signal devices distributed along the railway, including but not limited to obtaining multi-source signal status data from signal devices such as signal lamps, switch machines, track circuits, consoles, power distribution panels, etc. The multi-source signal status data obtained from each signal device is defined as the original multi-source signal status data.

[0061] At the same time, use stream processing technology to perform real-time processing and logical operations on the original multi-source signal status data, which can complete the processing and operation of the original multi-source signal status data in a relatively short time, ensuring the real-time nature of the original multi-source signal status data.

[0062] S102: Preprocess the original multi-source signal status data to obtain the preprocessed multi-source signal status data.

[0063] Perform preprocessing operations such as cleaning, format conversion, and timestamp alignment on the original multi-source signal status data to obtain the preprocessed multi-source signal status data.

[0064] Through preprocessing, the quality of the data and the consistency in the time dimension can be ensured, avoiding misjudgment caused by time differences.

[0065] S103: Read the comparison rules, and perform consistency comparison on the preprocessed multi-source signal status data based on the comparison rules to obtain the comparison result.

[0066] The comparison rules are pre-configured in the system by the staff according to actual needs. The system reads the comparison rules, and the comparison rules include but are not limited to matching rules, anomaly detection rules, priority rules, and response rules, specifically as follows:

[0067] A. Matching rules

[0068] Define which signal status data need to match each other. The mutually matching signal status data will be subjected to consistency comparison, and the number of mutually matching signal status data is 2 or more.

[0069] B. Anomaly detection rules

[0070] Define the anomaly conditions, anomaly levels, anomaly types, and error ranges, and these four pieces of information correspond one by one.

[0071] The error range includes but is not limited to time error and position error.

[0072] C. Priority Rules

[0073] Defines the priority of each signal status data.

[0074] D. Response Rules

[0075] Defines the response methods corresponding to different exception levels. The response methods include recording exception information, issuing corresponding alarm prompts, notifying the control center, etc.

[0076] After reading the comparison rules, perform consistency comparison. During a certain consistency comparison process:

[0077] First, based on the matching rules, clarify the range of pre - processed multi - source signal status data participating in the consistency comparison.

[0078] After that, based on the anomaly detection rules, perform consistency comparison on the pre - processed multi - source signal status data participating in the consistency comparison.

[0079] When the pre - processed signal status data participating in the consistency comparison triggers an abnormal condition, and the difference between the pre - processed signal status data participating in the consistency comparison is not within the error range, all the pre - processed signal status data participating in the consistency comparison are recognized as abnormal data, and the comparison result is recognized as an abnormal result.

[0080] When the pre - processed signal status data participating in the consistency comparison triggers an abnormal condition, and the difference between the pre - processed signal status data participating in the consistency comparison is within the error range, all the pre - processed signal status data participating in the consistency comparison are recognized as normal data, and the comparison result is recognized as a normal result.

[0081] When the pre - processed signal status data participating in the consistency comparison does not trigger an abnormal condition, regardless of whether the difference between the pre - processed signal status data participating in the consistency comparison is within the error range, all the pre - processed signal status data participating in the consistency comparison are recognized as normal data, and the comparison result is recognized as a normal result.

[0082] Then, determine the exception level and exception type according to the abnormal condition triggered during the consistency comparison.

[0083] S104: Feedback the abnormal results in the comparison result.

[0084] After obtaining the comparison result, based on the response rules, obtain the response method corresponding to the exception level according to the exception level; based on the priority rules, obtain the priorities corresponding to all the pre - processed signal status data in the abnormal result.

[0085] Feed back the abnormal results and priorities in the comparison result to the staff according to the response method.

[0086] In the second embodiment, after obtaining the comparison result, record the comparison result, specifically record: comparison time, source of signal status data, whether it is abnormal, type of abnormality, level of abnormality, response method. Store the comparison result in a log file, and classify and store the log file according to a predetermined type, and the predetermined type includes but is not limited to time and type of abnormality. To reduce the occupation of storage space, set a first predetermined period, delete the log files that exceed the first predetermined period, and only retain the log files within the first predetermined period.

[0087] In the third embodiment, after obtaining the comparison result, visually display the comparison result to the staff, and the display form includes but is not limited to charts and reports, and the display content includes but is not limited to comparison reports, abnormal data lists, etc.

[0088] During the execution of the foregoing three embodiments, back up all the data generated during the execution process according to a second predetermined period to prevent data loss, and encrypt the predetermined sensitive data to ensure the security of the data.
