The invention provides an error identification method and apparatus for a continuous flat press cluster control system. The error identification method comprises steps of: detecting the error information of the continuous flat press cluster control system; according to the detected error information, determining the error grade string of the continuous flat press cluster control system; performing hamming coding on the error grade string in order to obtain a coded error hamming code for identifying the channel generating an error in the continuous flat press cluster control system. The error identification apparatus may execute the above error identification method. The error identification method and apparatus may achieve accurate error identification, may identify error grades with variable numbers within a certain range just by using the coding bit of an error condition word with fixed bits in an error identification process, and do not need to change the data line width of a hardware unit required by transmission and computation.
