The invention discloses an integrated rim type wheel sensor axle counting interference recognition system and method. The method comprises the steps that S1, information of wheels passing above a first wheel sensor SYS1 and a second wheel sensor SYS2 is collected through the first wheel sensor SYS1 and the second wheel sensor SYS2; s2, sequentially performing AD acquisition, filtering, differentiation and analog-to-digital conversion processing on the received wheel information through an evaluation board to obtain a corresponding digital pulse signal; and S3, performing logic judgment processing on the obtained digital pulse signal through an axle counting logic processing module to obtain abnormal/normal pulse identification information, and identifying interference to perform redundancy. According to the symmetrical design of the integrated sensor, logic processing calculation can be carried out through ingenious combination of train speed, section occupation/idle information, direction information, pulse width relation and other information, the axle counting error situation caused by most of electromagnetic interference can be effectively recognized, and on the premise that safety is guaranteed, the accuracy of axle counting is greatly improved. And the availability of the axle recording equipment is greatly improved.
