The invention discloses a method for computing a signaler trans-
voltage command. The method specifically comprises the following steps of: enabling a zone
control system to acquire the position of the signaler and the external section of the signaler; judging whether the external section of the signaler is in an occupied state or not, if so, determining the position of a
train which is closest to the signaler; and judging whether the head and the
tail of the
train cross the signaler or not according to a position relation between the
train and the signaler, computing to generate a corresponding signaler trans-
voltage command, sending the signaler trans-
voltage command to an
interlock which corresponds to the zone
control system, and controlling a moment when the signaler is switched from an enabling
signal to an inhibiting
signal by using the
interlock. Due to the adoption of the method, undesired
emergency brake of the train is avoided, the running efficiency of the train in a CBTC (Communication Based
Train Control) mode is increased, and running of multiple rows of CBTC trains in the same
route or the same zone is realized.
