ABSTRACT
Aiming at the ploblem that the traditional error correction code can not determine the code length and the optimal order, applied Hadamard matrix to the error correcting codes, a fault recognition method based on Hadamard error correction code support vector machine was proposed. Compared with the traditional error correction code, Hadamard error correcting code was more simple and the codebook was more advantageous. The method was verified by the sample of different classes of UCI database, and compared with the traditional "one to many" methods. Meanwhile, the method was applied to the fault identification of transmission mechanism of reciprocating compressor. The results show that Hadamard error correction code support vector machine has higher recognition accuracy in the case of a small number of classifiers and good stability for samples of different categories.
