Virtual transponder triggering method

The invention discloses a virtual transponder triggering method. The method comprises the following steps: acquiring a track electronic map and train information of a current period; performing route searching according to the track electronic map and the train information in the current period to generate a front route signal list of the train in the current period; generating a running track signal list of the train in the current period according to the front route signal list of the train in the current period; and acquiring a virtual transponder group to be triggered in the current period according to the running track signal list of the train in the current period, and triggering the virtual transponder group, so that a vehicle-mounted system triggers the virtual transponder group message. According to the method, the triggering of the virtual transponder is completed by taking a group as a unit, and compared with a traditional method of independently triggering the virtual transponder by taking a circl
