BACKGROUND

In the field of railway station computer interlock technology, when the route selection adopts a dynamic search scheme, such as the shortest path search algorithm, the shortest path search algorithm is used to calculate the shortest path from one signal point to all other signal points. The main feature is extending to the outside layer by layer with the start point as a center, until it extends to the end point, signal points that need to be traversed and calculated are a lot, more computing resources are occupied. Moreover, the number of routes that may be searched is large, resulting in a difference between the actual usable route and the interlock table given by the design units.
For example, when there are multiple routes from signal point A to signal point B, the design units only allows one of the paths to be arranged, and the other paths are not allowed to be arranged; while the dynamic search mode considers all the multiple paths from signal point A to signal point B as effective routes. The design units requires that the route between the specified number of signal points sends to the other devices a route state with a fixed unique number; whereas the dynamic search mode dynamically retrieves the route when receiving an operation command, and the route has bad capability of maintaining a fixed unique number.
Therefore, in order for the actual route to be consistent with the interlock given by the design units, those skilled in the art urgently need to develop a route control method that enables the route to maintain a unique number.

A specific embodiment of the present disclosure further provides a route control device based on a static interlocking table, wherein the device comprises: a conversion unit configured to convert an original interlocking table provided by design units to a static interlocking table; a selection unit configured to select a route in the static interlocking table according to a routing command.
