Description

Automatic calculation method, device and medium for forecast beacon and restart beacon distance

Technical Field

The present invention relates to a train signal control system, and more particularly, to an automatic calculation method, apparatus, and medium for a forecast beacon and a restart beacon distance.

Background

Currently, in most subway signal systems, the spot backup mode is an operation mode that is degraded as backup. When the continuous ATP function fails or is specially required, the signal system can start the point-type backup mode to organize train operation. In the point backup mode the on-board system controls the train operation by means of the trackside variable information received from the active beacons, so that the active beacons need to be arranged on the line. The distance between the forenotice beacon and the restarting beacon in the active beacon needs to meet the minimum value in the real-time parameter, if the distance between the forenotice beacon and the restarting beacon is too small, the forenotice beacon is too close to be arranged, the state of the trackside equipment such as a front annunciator and a turnout can not be known in advance by a train, the train can be decelerated in advance, finally, the train stops in front of the restarting beacon, and the running efficiency of the train in a point-type standby mode is seriously influenced. Therefore, in the system design verification stage, it is necessary to calculate the distance between the advance notice beacon and the restart beacon and to check that the advance notice beacon and the restart beacon are at least the minimum value of the real-time parameters.

The traditional method for calculating the distance between the forenotice beacon and the restarting beacon is to find the forenotice beacon and the restarting beacon corresponding to the annunciator in the backup mode variable table IBBM according to the name of the annunciator on the signal plan, return to the signal plan to obtain the equipment kilometer sign corresponding to the forenotice beacon and the restarting beacon, and manually calculate the absolute value of the equipment kilometer sign between the forenotice beacon and the restarting beacon corresponding to each annunciator one by one so as to obtain the distance. The method needs to switch the signal plane diagram and the backup mode variable table back and forth, and is easy to error the distance calculation caused by error finding equipment; and the labor is completely relied on, so that the time consumption is high and the efficiency is low.
