[0038] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve corresponding technical effects can be fully understood and implemented accordingly. The embodiments of the present invention and the various features in the embodiments can be combined with each other without conflict, and the technical solutions formed are all within the protection scope of the present invention.

[0039] Embodiment 1

[0040] like Figure 1 As shown, an embodiment of the present invention provides a rail transit power supply operation and maintenance method based on big data, comprising the following steps S101 to S105:

[0041] Step S101: Collect target rail transit power supply data.

[0042] For example, Kettle is used to collect the target rail transit power supply offline data, and Flume is used to collect the target rail transit power supply real-time data. The rail transit power supply offline data is the offline static rail transit power supply data, and the rail transit power supply real-time data is the rail transit power supply data obtained from the device in real time.

[0043] Step S102: Processing the target rail transit power supply data according to preset analysis rules.

[0044] For example, the target rail transit power supply data is processed according to preset analysis rules through Spark SQL and / or Spark Streaming. The preset analysis rules, for example, analyze the temperature of the voltage equipment and take the average temperature per hour. Therefore, the original collected data needs to be normalized.

[0045] Step S103: storing target rail transit power supply data.

[0046] For example, the target rail transit power supply data processed by the preset analysis rules is obtained through Kafka, and the target rail transit power supply data is stored in Mongodb or FastDFS.

[0047] Step S104: searching the target rail transit power supply data according to the preset warning rules to obtain the target warning information.

[0048] For example, ElasticSreach retrieves the target rail transit power supply data according to the preset warning rules to obtain the target warning information. After obtaining the normalized data, it is stored in the ElasticSreach index for fast retrieval. For example, if the temperature of the voltage equipment is higher than 80 degrees for 4 consecutive hours, if this condition is met, it means that there may be a problem with the voltage equipment and it needs to be dealt with in time.

[0049] Step S105: Display target warning information.

[0050] For example, information about voltage devices with problems is displayed on the display interface.

[0066] Step S1: User logs in and obtains analysis data request;

[0067] For example, a user enters a password and logs into the system after verification.

[0068] Step S2: The business system initiates a request for analysis data to the algorithm library / rule library;

[0069] For example, after the user specifies the analysis rules, the analysis of characters is started.

[0070] Step S3: the algorithm library / rule library obtains offline calculation data from Mongodb (structured data) / FastDFS (unstructured data);

[0071] For example, basic data is obtained according to analysis rules specified by the user.

[0072] Step S4: Mongodb / FastDFS performs normalized data processing;

[0073] For example, clean up irregular basic data.

[0074] Step S5: Normalize data processing and consume data to Kafka.

[0075] For example, sending normalized data to kafka.

[0078] Step S7: linking data sources (detection and monitoring system, production operation system) to access data;

[0079] For example, connected to detection and monitoring systems, production operation systems.

[0080] Step S8: Read data from the data source (detection and monitoring system, production operation system);

[0081] For example, reading detection and monitoring system and production operation system data.

[0082] Step S9: The data collection program returns the collected data to Kafka;

[0083] For example, Kafka obtains collected data.

[0084] Step S10: The normalized data is directly stored in Mongodb / FastDFS.

[0085] For example, storing normalized data directly into Mongodb / FastDFS.

[0086] Step S11: The offline calculated data is returned to the algorithm library.

[0087] For example, the normalized data is stored.

[0088] Step S12: Real-time computing initiates a data consumption request to Kafka;

[0089] For example, real-time computing initiates data consumption requests to Kafka.

[0090] Step S13: Write to Mongodb according to algorithm rules;

[0091] For example, normalized data is written to Mongodb according to algorithmic rules.

[0092] Step S14: Return the result value to the business system;

[0093] For example, the result value will be returned to the business system.

[0094] Step S15: The business system interface obtains the calculated result data for presentation;

[0095] For example, the display interface shows that the temperature of a voltage device is higher than 80 degrees for 4 consecutive hours.

[0096] Step S16: For common business data, the user directly initiates a query request to the business system;

[0097] For example, a user queries voltage devices whose temperature is higher than 80 degrees for four consecutive hours.

[0098] Step S17: The business system initiates a data query request to the Mongodb component of the big data platform;

[0099] For example, query based on the condition that the temperature is higher than 80 degrees for 4 consecutive hours.

[0100] Step S18: The Mongodb database returns data to the business system;

[0101] For example, return the query results.

[0102] Step S19: The result data is displayed and presented to the user interface.
