Due to the convenience and high efficiency of rail transit, the application of the rail transit system in the society is more and more extensive, different from conventional vehicles, the communication systems and subsystems on trains in the field of rail transit are various, the used communication technologies mainly comprise Ethernet, MVB (multifunctional vehicle bus) and the like, communication equipment is installed in a limited space, and in order to facilitate communication fault analysis and positioning, a recording module is designed on the trains to record communication data information on the trains in real time. The recorded information is stored in the recording module in a file form, and because the number and the types of the recorded files are large, under the condition that the operation space and the resources of application personnel are limited, how to safely, quickly and conveniently find and download the target recorded file becomes a problem;
in the traditional method, a specially responsible application person traverses all record files stored in a record module according to identification information of a required record file, searches for related files matched with the identification information, and selects a required target record file from the related files for downloading.
In order to solve the problems, the invention provides a method and a system for automatically downloading a train communication data recording file, which can safely, quickly and conveniently find out and download a target recording file from a plurality of recording files in a train recording module to a portable storage device. Various embodiments of the present invention will be described below with reference to the accompanying drawings.
Example one

And generating a configurable file containing preset downloading rules by combining the storage format parameters of the recording module to which the target recording file to be downloaded belongs.
Wherein, the storage format parameters of the recording module comprise the following parameters: recording the initial recording time of the file, the full storage time of the file and the corresponding sequence number of the file in the recording module; in practical applications, the full time of the recorded file may also be referred to as: the recording time when a file is full refers to the time when the file reaches a specified size during recording.
In practical application, the names of the record files in the track traffic field communication record module are generally named as follows: the sequence number of the recording time file of the initial recording time file full; for example: 201903131415_201903141718_1, this example shows that the recording start time of the file is: 14 hours and 15 minutes in 3, 13 and 13 of 2019, the time when the file record reaches the specified size is as follows: the file is ranked by 18 points in 2019, 3, 14 and 17 hours, and the ranking number of the file is 1.
Specifically, in an embodiment of the present invention, the downloading rule of the target recording file is embodied by a downloading mode flag in the configurable file, where the downloading mode flag includes two downloading mode flags, and when the downloading mode flag value is a first preset flag, a first downloading parameter corresponding to the flag includes: downloading starting sequence number, downloading sequence and target downloading quantity; when the download mode flag value is a second set flag, the second download parameter corresponding to the flag includes: a download start time and a target download duration.
In practical application, the download mode flag may be embodied by a "mode" flag in the configurable file, when the value of the "mode" is equal to 0, the download is performed according to the serial number of the file, and the corresponding first download parameter includes: the starting sequence number of the download, the download sequence and the target download number, when a failure occurs, several latest files are usually downloaded, so that the latest sequence number can be deduced from the latest sequence number in a reverse order.
Correspondingly, when the value of "mode" is equal to 1, a downloading rule is set according to the starting time set in the file and the time for downloading the long record, and then the name of the record file is matched according to the starting time parameter. When the occurrence time of the fault is known, the target downloading time length can be set according to the requirement based on the specific time of the fault occurrence or the set time before the fault as the starting time. By adopting the downloading rule, the workload can be greatly reduced on the basis of ensuring the reliability.
Further, after a configurable file (such as an xml-type configurable file) is generated, if data related to train communication is acquired through some illegal data acquisition channels, potential safety hazards are caused, and in order to prevent recorded data of a train from being illegally downloaded and utilized, the generated configurable file needs to be encrypted, specifically, the xml file serving as the configurable file can be encrypted by using an encryption algorithm, and then the encrypted configurable file is placed in a U disk, so that the method comprises the following operations:

Step S130, parsing the decrypted configurable file to obtain a download rule of the target record file contained therein.
When the device is used by a user, a portable storage device (such as a U disk) provided with an encrypted configurable file (such as an encrypted xml file) is inserted into the train recording module; the recording module can immediately detect that a USB flash disk is inserted, then judges whether an encrypted configurable file containing a preset downloading rule exists in the accessed storage equipment, if so, the encrypted xml file is decrypted according to a corresponding decryption algorithm, the decrypted xml file is stored in a drive symbol of the recording module, and a CPU of the recording module reads and analyzes the decrypted xml file from the drive symbol.
The xml file can obtain the download rules contained therein by parsing the decrypted xml file, and then the following steps are performed:
and step S140, automatically matching a target record file to be downloaded in the recording module according to the acquired downloading rule, and transmitting the target record file to the accessed storage device.
Specifically, in this step, the download rule of the target record file includes a download mode flag of the configurable file, including two download mode flags, where the download mode flag can embody the download rule in the corresponding configurable file, and specifically, in step S140, the target record file is matched based on the download mode flag by: when the download mode flag value is a first set flag, the first download parameter corresponding to the flag includes: downloading starting sequence number, downloading sequence and target downloading quantity; when the download mode flag value is a second set flag, the second download parameter corresponding to the flag includes: a download start time and a target download duration.
In practical application, the download mode flag may be embodied by a "mode" flag in the configurable file, when the value of the "mode" is equal to 0, the download is performed according to the serial number of the file, and the corresponding first download parameter includes: the starting sequence number of the download, the download sequence and the target download number, when a failure occurs, the latest several files are usually required to be downloaded, so that the latest sequence number can be deduced from the latest sequence number in a reverse order.
Correspondingly, when the value of "mode" is equal to 1, a downloading rule is set according to the starting time set in the file and the time for downloading the long record, and then the name of the record file is matched according to the starting time parameter. When the occurrence time of the fault is known, the target downloading time length can be set according to the requirement based on the specific time of the fault occurrence or the set time before the fault as the starting time.
Further, in order to ensure the safe transmission of the train communication data, in consideration that the decrypted configurable file stored in the recording module may also be illegally acquired or tampered, a policy is taken to delete the decrypted downloaded file after the downloading action is completed, and therefore, in one embodiment, the method further includes the following operations: and judging whether the decrypted configurable file is analyzed completely, if so, deleting the stored decrypted configurable file, otherwise, judging again after setting a time period until the decrypted configurable file is completely analyzed.

Specifically, the processing flow of the method of the present invention for encrypting the configurable file is shown in fig. 2. And then the recording module matches the files in the recording module according to the downloading mode and the number of the downloaded files configured in the xml file, the matching is successful, and finally the target recording file is written into the U disk. The decrypted configurable file deleting operation is started in time by adopting the operation, so that the automatic deletion of the risk file is realized, and the safety of the train communication data is ensured to the greatest extent.
The invention designs an encrypted configurable file as an intermediate downloading tool aiming at the file downloading of a recording module in the field of rail transit, and an application person only needs to modify relevant parameters of the configurable file, the xml file as the encrypted configurable file is stored in the U disk, and then the U disk is inserted into the recording module, so that the automatic matching downloading of the train recording file can be carried out, an application person does not need to select and drag the file to the U disk, the flexibility and the convenience of downloading the event recording device file by the application person are improved, particularly under the conditions that the operation space of the application person on the train is limited and the computer is inconvenient to carry with, the active downloading of the encrypted file configured by the U disk is particularly necessary, and in addition, the encrypted xml download file improves the safety of the data of the recording module, and can prevent illegal tampering and acquisition of the recorded data.
