With the aim to improve the fault‐tolerant performance of GNSS based deeply integrated train positio‐ning system ,a FRBFNN based fault detection algorithm was proposed referring to the basic principles of fuzzy system and neural network .The FRBFNN based fault detection model for the integrated train positioning sys‐tem was established ,while the corresponding training algorithm was designed based on the thought of immuni‐ty differential evolution .With respect to the issues of fault isolation of integrated train positioning and system reconfiguration ,the rules for state transition of integrated system structure were defined ,and the fault‐tolerant control process was also designed aiming at increasing the fault tolerant control performance of the integrated train positioning system .The effectiveness and practicality of the proposed model and solution were verified by computer simulation ,using the real operation data of a train in a section of the Qinghai‐Tibet railway .
