The invention relates to the technical field of power line carrier communication, and particularly provides a power line carrier communication data processing method and device, and the method comprises the steps: carrying out the mapping of a plurality of target data through a first mapping rule, and writing the target data into a plurality of memories; in the reading stage of each iterative operation cycle, mapping the logic reading address according to a first mapping rule to obtain a physical reading address, and performing data reading on the corresponding target data according to the physical reading address; performing fast Fourier calculation according to the plurality of parallel radix-4 operation modules to obtain a calculation result; in a writing stage of a non-last iterative operation period, writing a calculation result back to an original physical address to cover original data according to a first mapping rule; and in the write-in stage of the last iterative operation period, generating a physical write-in address corresponding to the calculation result according to a second mapping rule, and writing the calculation result into the corresponding physical write-in address. According to the method, the calculation speed and the read-write speed are effectively improved, the processing time is shortened, and the timeliness is ensured.

This invention provides a method and related products for converting payload files in heterogeneous databases. The method includes: in response to a conversion command, obtaining a payload file from the heterogeneous database; parsing the payload file to obtain a parsing result; obtaining an ordered index list corresponding to a target file in a local database, the target file being used to store the converted payload file; determining the target file to be written based on the ordered index list; converting the parsing result to obtain a conversion result recognizable by the local database; and writing the conversion result to the target file. This method enables the conversion of payload files between heterogeneous databases, thereby supporting further processing of payload files by domestic databases.

The present application relates to a kind of round steel peeling machine " five heart coaxiality " detection and adjustment method for the coaxiality of blank feeding roller, front guide, rotary cutter head, rear guide and clamping trolley five components of large-scale round steel peeling machine, install front and rear support sleeve, with the reference of front support sleeve, detect and adjust the coaxiality error of front guide and cutter head, install test bar, detect and adjust feeding roller, detect and adjust rear guide, detect and adjust trolley, avoid the quality problem of processing product caused by the large error of equipment " five heart coaxiality " error, through special tooling, support test bar, and test bar is in good stress state, clamping roller does not clamp test bar, which is beneficial to maintain the accuracy of test bar, and the detection and adjustment process is reasonable, and the detection and adjustment precision is high, and the efficiency is high.
