Abstract

The application discloses a route unlocking method and a device. A first storage area and a second storage area in an interlocking route table are updated, the real-time properties of section status information and a train address which are recorded in the first storage area and the second storage area are ensured, and then, the interlocking route table is further accessed to obtain the current address of a train and the current status of each section; according to the current address of the train, route signs are maintained, and finally, according to the current route sign and the section status information, the unlocking condition is judged; compared with the prior art, the method disclosed by the application simplifies an unocking judgment process, completes the examination of the section status information while updating the interlocking route table, the temporary collection for the status of a track relay is not required, the unlocking efficiency is improved, and besides, the erroneous judgment for the unlocking conditions cannot be generated by the failure and the abnormal status of the track relay, and the correct unlocking of the route is ensured.

Description

technical field [0001] The present application relates to the technical field of rail transit signals, in particular to a method and device for unlocking an approach. Background technique [0002] In the rail transit system, after the approach is processed, the turnouts in each section of the approach are locked at the specified position to ensure that it cannot be rotated in any automatic or manual way, so that the hostile approach cannot be established. Correspondingly, when you want to cancel the route, you need to unlock the route. According to different situations of route usage, the existing unlocking methods mainly include route normal unlocking, total cancel route unlocking and total manual delay unlocking. Different unlocking methods correspond to different unlocking conditions, if and only if the route status satisfies the corresponding The route can be unlocked only when the unlocking condition is met. [0003] Wherein, the normal unlocking of the route refers t...
