Description

Technical Field

[0001] The present invention relates to the technical field of multi - terminal data interaction, and in particular to a multi - terminal data interaction method and system based on rail transit. Background Art

[0002] Rail transit is a complex system integrating multiple specialties and trades. It usually consists of rail lines, stations, vehicles, maintenance and repair bases, power supply and transformation, communication signals, command and control centers, etc. The transportation organization, function realization, and safety assurance of urban rail transit should all follow the objective laws of rail transit. In terms of transportation organization, centralized dispatching, unified command, and train operation according to the operation diagram should be implemented. In terms of function realization, various related specialties such as lines, stations, tunnels, vehicles, power supply, communication, signals, mechanical and electrical equipment, and fire protection systems should all ensure good conditions and normal operation. In terms of safety assurance, it mainly relies on train operation organization and normal operation of equipment to ensure the necessary train intervals and correct train routes. To ensure the safe and punctual operation of trains, under the principle of centralized dispatching and unified command, train operation organization, equipment, vehicle maintenance, equipment operation management, safety assurance, etc. are all regulated by a series of rules and regulations. Train operation is a system of multi - specialty and multi - trade cooperation, an orderly linkage and highly time - efficient system centered around safe train operation; Traditional solutions usually obtain a data management platform applied to rail transit management to understand multiple ports in the platform, so as to facilitate subsequent multi - terminal data interaction. By creating a communication token between the sending end and the receiving end, it is convenient to verify during subsequent multi - terminal data interaction, improving the reliability and accuracy of data interaction. However, when using traditional solutions, the following technical problems exist: Traditional multi - terminal data interaction methods based on rail transit require full - network support. When there is a local network anomaly, some data will be lost during transmission, resulting in insufficient integrity of data transmission and insufficient protection measures for data. Summary of the Invention

[0003] The purpose of the present invention is to solve at least one of the technical problems in the background art, and provide a multi - terminal data interaction method and system based on rail transit.

[0004] To achieve the above purpose, the present invention provides a multi - terminal data interaction method based on rail transit, including: Obtain rail transit data through an independent terminal; Transmit the data to the cloud for backup; Transmit the data to the interaction terminal. The interaction terminal identifies the data and generates an identification code, and then transmits the data to the receiving terminal; The receiving terminal obtains the data and returns interaction data; The interaction terminal identifies the interaction data and sends it to the cloud; The cloud identifies the interaction data and returns it to the independent terminal.

[0005] According to one aspect of the present invention, after obtaining data through an independent terminal, the data is saved in a local server. The local server generates an identification code for the data according to the type and specific content of the data, and subsequently retrieves the corresponding data according to the identification code.

[0006] According to one aspect of the present invention, when the data is transmitted to the cloud for backup, a data number is assigned to the data. The data number is generated according to the data type and data content. After the data number is generated, a secondary confirmation is performed. The data number has no duplicates and the format is unified according to the data type.

[0007] According to one aspect of the present invention, the identification code generated when the interaction terminal identifies the data is uploaded to the cloud. The cloud retrieves relevant data according to the data identification information of the identification code for comparison to confirm whether the data is complete and accurate. If so, the priority of the identification code of the data is divided according to the content and type of the data.

[0008] According to one aspect of the present invention, before the interaction terminal transmits the data to the receiving terminal, it detects whether there is a request to obtain data. It preferentially transmits the data that meets the request criteria to the requesting end, and determines the transmission order of the data according to the priority of the identification code of the data. When transmitting the data, the data stream is split into multiple data packets, and the data packets are transmitted in parallel through different network interfaces.

[0009] According to one aspect of the present invention, after the receiving terminal obtains the data, it identifies the data. After identification, it calls relevant data in the cloud for comparison to confirm whether the data is complete and accurate. If so, the receiving terminal generates corresponding interaction data according to the obtained data for transmission, and before returning the interaction data, the receiving terminal locally stores the interaction data; If not, the receiving terminal calls the locally stored data for transmission.

[0010] According to one aspect of the present invention, when the interaction terminal receives the interaction data returned by the receiving terminal within a preset time range, it retrieves the identification code of the relevant data according to the received interaction data, determines the independent terminal that needs to return the interaction data according to the identification code, and transmits the interaction data and the identification code to the cloud; When the interaction terminal does not receive the interaction data returned by the receiving terminal within the preset time range, it returns an exception message to the cloud and the independent terminal.

[0011] According to one aspect of the present invention, when the cloud identifies and determines that the interaction data is normal, it backs up the interaction data to the relevant data, generates an independent identification number for the interaction data, and returns the interaction data to the corresponding independent terminal; When the cloud determines that the interaction data is abnormal, it stops returning the interaction data, and transfers the interaction data and the abnormal information to the interaction end. The interaction end compares and judges the interaction data returned by the cloud and the interaction data returned by the receiving end. If the judgment results are consistent, the interaction data is transferred to the receiving end again for confirmation with the interaction data stored locally at the receiving end.

[0012] To achieve the above object, the present invention further provides a multi-terminal data interaction system based on rail transit, including: A data acquisition module, which acquires rail transit data through an independent terminal; A data backup module, which transfers the data to the cloud for backup; A data transmission module, which transfers the data to the interaction end. The interaction end identifies the data and generates an identification code, and then transfers the data to the receiving end; A data interaction module, which acquires data through the receiving end and returns interaction data; A first data identification and sending module, which identifies the interaction data through the interaction end and sends it to the cloud; A second data identification and sending module, which identifies the interaction data through the cloud and returns it to the independent terminal.

[0013] To achieve the above object, the present invention further provides an electronic device, including a processor, a memory, and a computer program stored on the memory and executable on the processor. When the computer program is executed by the processor, it implements the multi-terminal data interaction method based on rail transit as described above.

[0014] To achieve the above object, the present invention further provides a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, it implements the multi-terminal data interaction method based on rail transit as described above.

[0015] According to the solution of the present invention, the present invention stores local backups when the data is initially transferred and when the interaction data is returned, and performs cloud backups on the data when the data passes through the cloud, effectively preventing data loss caused by local area network anomalies during the data transmission process, ensuring the integrity of the data, and facilitating the retrieval of relevant data again in case of anomalies; When the present invention performs data transmission, it divides the data stream into multiple data packets and performs parallel transmission using different network interfaces, reducing the transmission delay, increasing the bandwidth, and improving the reliability of data transmission.

After the data number is generated, it needs to be manually reconfirmed to ensure the accuracy of the data number, effectively prevent abnormal data numbers, ensure that the data numbers are non-repetitive and the format is unified according to the data type.

[0022] According to an embodiment of the present invention, if an abnormality occurs when the independent terminal transmits data to the interaction terminal, the interaction terminal determines whether to call the backup data in the cloud according to the data priority. In the case of high priority, the backup data in the cloud is preferentially retrieved for subsequent data interaction to prevent data interaction interruption.

[0023] According to an embodiment of the present invention, the identification code generated when the interaction end identifies data is uploaded to the cloud. The cloud retrieves relevant data according to the data identification information of the identification code for comparison, confirms the integrity and accuracy of the data, and assigns priorities to the identification codes of the data according to the data content and data type.

[0024] In this embodiment, the above-mentioned relevant data includes both the current data backed up in the cloud and the relevant historical data backed up in the cloud, specifically depending on the call requirements of the data during the interaction process. For example, during the process of data comparison, analysis, or processing, it may be necessary to call the current data and historical data for comprehensive analysis.

[0025] In this embodiment, by assigning priorities to the identification codes of the data, when the data is transmitted and processed, the data with higher priorities is preferentially processed, thereby improving the response speed and efficiency of the system and ensuring that key information can be processed in a timely manner.

[0026] According to an embodiment of the present invention, before the interaction end transmits data, it detects whether there is a request to obtain data, preferentially transmits the data that meets the request criteria to the request end, and determines the transmission order of the data according to the priority of the data identification code. When transmitting the data, the data stream is split into multiple data packets, and the data packets are transmitted in parallel through different network interfaces.

[0034] According to an embodiment of the present invention, when the cloud determines that the interaction data is abnormal, it stops the return of the interaction data, transmits the interaction data and the exception message to the interaction end for comparison. The interaction end compares and determines the data returned by the cloud and the data returned by the receiving end. If the judgment results are consistent, the data is transmitted to the receiving end again to confirm with the interaction data stored locally at the receiving end. After confirmation, the interaction data is returned, and then the interaction end identifies the interaction data and sends it to the cloud. The cloud identifies the interaction data and returns it to the independent terminal, forming multi-terminal data interaction.

The interaction terminal detects the request for acquiring data, preferentially transmits the data that meets the request according to the request priority. After processing the data transmission of the request terminal, it continues with data interaction, transmits relevant data to the receiving terminal. After the receiving terminal acquires the data, it identifies the data, and after identification, it retrieves relevant data from the cloud for comparison to confirm the integrity and accuracy of the data.
