Method for collecting compressed files, terminal device and medium

By generating dynamic regular expressions and filename queue judgment in the mobile communication data acquisition platform, only incrementally compressed files from the FTP server are downloaded, which solves the network congestion and memory overflow problems caused by large data volume transmission, and improves data acquisition efficiency and system stability.

AI Technical Summary

Technical Problem

When the mobile communication data acquisition platform collects compressed files from the FTP server, it causes frequent large data transfers and network congestion, affecting data acquisition efficiency and system stability.

Method used

By generating dynamic regular expressions to filter compressed files generated by the FTP server, and combining this with a filename queue to determine whether to download the target file, only incremental files are downloaded, thus avoiding duplicate downloads and processing.

Benefits of technology

This reduces the amount of data downloaded and processed, improves the system stability and efficiency of the data acquisition platform, and avoids network congestion and memory overflow.

Abstract

The application discloses a compressed file collection method, a terminal device and a computer readable storage medium, and the compressed file collection method comprises the following steps: generating a dynamic regular expression based on a current time point and a preset time granularity; determining a target compressed file that meets the dynamic regular expression in a compressed file generated by a file transfer protocol (FTP) server; and downloading the target compressed file when a first file name corresponding to the target compressed file is not saved in a file name queue, wherein the file name queue is used for saving second file names corresponding to files downloaded in a first period. The compressed file is double-filtered through the generation time of the compressed file and the file name queue, so that the repeated downloading of the compressed file is avoided, and the effect of improving the data collection efficiency is achieved.
