The present invention relates to apassenger train car starting up controlled system based on information integrated which includes ignition switch information acquisition module, back cabin door switch information acquisition module and starter control module. Ignition switch information acquisition module and back cabin door switch information acquisition module are made up of microcontroller, CAN communication unit, switch information acquisition unit and supporting circuit respectively, and collects state information of ignition switch and back cabin door switch, and transfers to starter control module by CAN bus. The present invention possesses the beneficial effects: (1) implementing bus type control of passenger car starter without change passenger car starter; (2) on the basis of traditional passenger car starter controlled conditions and based on information integration, realizing multi-information synthetic judgment process and improving starting up controlled safety. (3) realizing functional spreading easily base on facing consumer demand.
