Method and system for automatically downloading train communication data record file

The invention provides a method and system for automatically downloading a train communication data record file, and the method comprises the steps: judging whether an encrypted configurable file containing a preset downloading rule exists in an accessed storage device or not, if yes, decrypting and storing the encrypted configurable file, obtaining the downloading rule associated with the target recording file through analysis processing, and finally, matching and obtaining the target recording file needing to be downloaded in the recording module automatically according to the obtained downloading rule. According to the technical scheme, the parameters in the encrypted configurable file containing the preset downloading rule are adjusted, so that the required record file can be automatically matched and downloaded by adopting different downloading rules, and the problems of complicated operation and high error probability in the existing downloading technology are solved. Meanwhile, the configurable file is
