constructing a production line feature set corresponding to the data allocation module based on the equipment information;
based on the fact that the production line feature set is matched with a standard feature set in a preset first configuration library, a first configuration rule and first configuration data which are associated with the standard feature set matched with the production line feature set are called;
configuring the data allocation module based on the first configuration rule and the first configuration data;
the second configuration module configures a data classification module connected with each PLC controller, and performs the following operations:
acquiring a third equipment identification code of the data allocation module connected with the data classification module through the data classification module;
based on the third equipment identification code, a production line equipment ordering table and a configuration record sent by the corresponding data allocation module are called;
based on the configuration record, a preset second configuration library corresponding to the first configuration rule is called;
based on the production line equipment sorting table, calling a second configuration rule and second configuration data from a second configuration library;
configuring the data classification module based on the second configuration rule and second configuration data;
the data allocating module allocates the online data of each data classifying module after the allocation is completed and integrates the online data to form second uploading data, and the method comprises the following steps:
when a data acquisition request of the data classification module is received, locating a first position of equipment corresponding to a PLC controller connected with the data classification module in a production line equipment ordering table;
extracting in-line data uploaded by a data classification module connected with a PLC (programmable logic controller) of equipment corresponding to a second position associated with the first position and sending the in-line data to the data classification module corresponding to the data acquisition request;
and/or the number of the groups of groups,
when a data acquisition request of the data classification module is received, the data acquisition request is analyzed, and a product identification code of a corresponding production product is determined;
based on the product identification code, inquiring a production product tracking table, and determining a data classification module of a data acquisition request of a production product corresponding to the product identification code from the previous request to be a data sender;
and extracting the online data uploaded by the data sender and sending the online data to a data classification module corresponding to the data acquisition request.
