(2) The requirement on maintenance and analysis personnel is high, and the dependence on technical personnel is strong.
(3) The existing ITCS data analysis links have a plurality of chains, and the time period from primary analysis to final confirmation is long.
(4) Data statistics is completed manually, workload is high, and problem tracking and tracing effects are difficult.

The back end of the manufacturer integrates research personnel, and the time period from the primary analysis to the final confirmation of the problems is long.
(2) The analysis work needs the locomotive to be put in storage and then the log is downloaded, the analysis can be carried out the next day, and the prior analysis cannot be carried out.
(3) The statistics of the related data such as the weekly newspaper, the monthly newspaper, the annual newspaper and the like are completed manually, the workload is high, and the problem tracking effect is difficult.
