The invention discloses a built-in intelligent failure diagnosis device based on data fusion mode recognition in the technical field of intelligent diagnosis of rail transport failure, which comprises a hardware structure and a software structure. The diagnosis device adopts high-speed DPS microprocessor and forms a distributive monitor processing system, that is, a two-level microcomputer structure with a supervisory machine and a subordinate machine with the help of a multiple-stage buffer and streamline mechanism in the high-speed data processing of the former. Besides, in coordination with sensor group information based on data fusion mode recognition and with the help of multiple neural network partial diagnosis and a decision-making level fusion mode recognition and intelligent diagnosis mechanism, the invention is able to realize the data storage, image display and long-distance data transmission, so as to complete the task of failure diagnosis. Therefore, the invention is able to detect the potential failure of key equipments for train, ensure the safety and reliability for the operation of key equipment in train and improve the operation efficiency and safety guarantee to the maximal extent.
