the NAS system establishes an interface with the PDM system, acquires and stores corresponding files from the PDM system according to a source data file list on a source data structure tree, and associates with corresponding source data files in the PDM system at the same time so as to ensure that the change of the source data files can be tracked; the NAS system is a server for storing source data files and difference data, the PDM system is a product data management system, design source data are stored in the NAS system, and the design source data are associated and stored with the PDM system source data files through the NAS system.
6. The method according to claim 1, characterized in that:
when the association relation between the source data files stored in the NAS system and the corresponding file data in the PDM system is established, the NAS system updates the source data structure tree of the system by reading the latest version information of the source data files in the PDM system, so that the structure tree files on the NAS are synchronous with the versions of the source data files corresponding to the PDM system, meanwhile, the data change information is captured in the PDM system according to the source data file items listed in the source data structure tree, and a source data file difference analysis log table is generated in the NAS system.
7. The method according to any one of claims 1 to 6, wherein:
when the NAS system is created and uses the account number and the access address, the required file is checked through the access address and the account number in the range of the local area network, or the required file is checked through the external network by using the VPN.
8. The method of any of claims 1 to 6, wherein the modification visualization management system comprises:
a source data file item change tracking list is created in the system, and related attribute information such as numbers, names, data categories, model numbers/part numbers, required quantity, suppliers, release times, update time and the like are displayed in a table form.
9. The method of any of claims 1 to 6, wherein highlighting the changed source data item on the source data structure tree comprises:
highlighting the data file with the engineering change source on the change tracking table by an informatization technical means so as to facilitate a researcher to track the engineering change of the whole life cycle of the source data; and referring to the source data file subjected to modification in the NAS system to evaluate, and confirming whether modification is implemented or not, and restoring normal display of the highlighted item through confirmation operation, so that engineering source data modification closed-loop management is realized, and the consistency of the simulator and the state of a true machine is ensured.
10. The method according to any one of claims 1 to 6, wherein:
setting priority and expected response time for NAS systems corresponding to different source data;
allocating caches for each NAS system according to the priority, wherein the NAS system with high priority allocates large cache capacity and the NAS system with low priority allocates small cache capacity; and monitoring each NAS system in real time, judging whether the cache capacity of the corresponding NAS system is matched with the corresponding priority, judging whether the actual response time of the corresponding NAS system is matched with the expected response time, and if not, distributing the cache for each NAS system again.
