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.
