A safe coding method for trackside train positioning information, including the following steps: compiling line position coding information of a train by using a redundancy coding scheme; identifying a coding string on a trackside signboard by an image collector, and sending the coding string to a vehicle-mounted safety computer after check; after performing multi-channel redundancy safe calculation on the coding string by the vehicle-mounted safety computer, looking up a table in a position database to obtain train position information corresponding to the coding string; and, updating a real position of the train according to the train position information determined by looking up the table. The method integrates redundancy, inverse check calculation and other means, thereby improving the safety of position calculation, remedying the reliability and safety defects of visual identification, and improving the positioning accuracy of passive train positioning based on a trackside device by an image collection technology.
