There is no such thing as including it, only whether it is useful or not.
In addition to the actual operation of the machine, intelligent manufacturing also need some information assistance.
These information falls in the big ocean of the network, artificial handsome selection of the fundamental reality, this time the need for information collection system assistance.
The main function of the network information acquisition system is: according to the user-defined task configuration, batch and accurate extraction of the Internet target web page of semi-structured and unstructured data, transformed into a structured record, saved in the local database for internal use or external release, the rapid realization of external information acquisition. As shown in the figure below:
The biggest features of the system are: flexibility of the collection method and accuracy of the collected data
Flexibility: any complex query and page layout can be handled flexibly
Accuracy: the resultant data is highly accurate (99%-100%)
