A railway turnout control method comprises: constructing a data space corresponding to a railway turnout area (101); adding a virtual railway turnout, in the data space, to an area in which a target turnback stopping point is located (102); adding the virtual railway turnout to a railway turnout list corresponding to a route along which a train drives into the area (103); and not releasing claim of the virtual railway turnout when the train stops at the turnback stopping point (104); Also provided is a railway turnout control system. The method and system can solve problems of deadlock of a turnback area and insufficient safety protection of crossed routes.

The present disclosure relates to a train-ground interlocking method and system for rail transit train operation control. In the train-ground interlocking method, a train is taken as a subject of wayside and carborne resource management, and the train actively calculates a required resource according to a “movement mission”, applies to a wayside at an appropriate time and location, uses the resource after obtaining a resource use authority, and actively releases the resource after use of the resource; and once the wayside allocates the resource to one of other trains, the resource cannot be reallocated without being released by the train. Compared to the prior art, the present disclosure has the following advantages: interlocking control of integration of the train and wayside equipment is achieved, rail transit is improved from original passive and indirect interlocking control of the train to active and direct interlocking control of the train, the train safety protection function and the utilization efficiency of wayside resources are further improved, and safe, timely and appropriate match between a movement behavior of the train and a status of the wayside equipment is truly realized.

Under a centralized control mode, the confirmation unit carries out separate turnout locking according to the target turnout position and carries out locking confirmation according to the driving confirmation signal. After locking confirmation, the position switch unit closes target turnout position switches and opens the other turnout position switches.

The discriminator voter only emits a control signal when the inputs thereof are not at variance.

A route control program generation device constructs a group of a plurality of environment models with different states in which the states of the plurality of environment models are changed in various manners. The environment model is constituted by a first moving body that is a control target and is present on a track divided into a plurality of sections, and a second moving body other than the control target, and searches for a state transition order where it is possible to achieve a request for causing the first moving body to move to a prescribed section by causing the first moving body to move to a destination while causing a state of one environment model to transition to a state of another environment model in response to the request. The route control program generation device constructs the group to match a prescribed restriction condition based on the restriction condition.
