Multi-protection-section protection method suitable for American dynamic beacon

Abstract

The invention discloses a multi-protection-section protection method suitable for an American dynamic beacon. A signal machine S01 is arranged at the starting point of a main route S01-S02; a signal machine S02 is arranged at the ending point of the main route S01-S02; a protection section T1101 is arranged in the signal machine S02; a turnout is arranged in the protection section T1101; a proximity dynamic beacon B0 is arranged outside the signal machine S01; a vehicle-mounted ATP runs through the proximity dynamic beacon B0 and obtains open state information of the signal machine S01 from the proximity dynamic beacon B0; if the vehicle-mounted ATP obtains that the signal machine S01 is not open from the proximity dynamic beacon B0, a train immediately implements emergency braking parking; and if the vehicle-mounted ATP obtains that the signal machine S01 is open from the proximity dynamic beacon B0, the vehicle-mounted ATP sets moving authority on the protection section T1101 regardsthat a turnout closest to the signal machine S02 in the protection section T1101 is locked in a reverse position by default and calculates an overspeed protection curve of a limited speed on the protection section according to a limited speed of the turnout in the reverse position. According to the multi-protection-section protection method suitable for the American dynamic beacon, by using an active treatment mode of the vehicle-mounted ATP, a problem of multiple protection sections is solved; and the vehicle-mounted ATP uses a most strict protection section turnout reverse speed limiting mode to perform fault guiding safety treatment.

Description

technical field [0001] The invention relates to rail transit technology, in particular to an urban rail transit signal system. Background technique [0002] Under the point control level of the urban rail transit signal system, if a specific project obtains the status of the signal machine in front of the train running and the position information of the switch in the protection zone through the American dynamic beacon, only one kind of protection zone can be associated with an American dynamic beacon For the situation involving protection of multiple protection zones, the same number of dynamic beacons should be set according to the actual approach and the lock position of the protection zone for a specific project, but usually, for the same signal machine, because the track Due to the limitation of spacing, the number of associated dynamic beacons should be set to 4 at most. [0003] Such as figure 1 As shown, the protection section of the route S01 to S02 is T1101, whic...

Problems solved by technology

[0004] In the prior art, for the case where there are multiple protection zones on one main route, to realize the safety protection of the range of the protection zone under the point type, it is necessary to configure the same number of proximity dynamic beacons as the protection zone may establish, When the train passes the signal at the entrance of the main approach, the vehicle-mounted ATP obtains the forward approach information and the position information of the switch in the protection section through the proximity dynamic beacon, and then calculates the train control curve to control the train to stop in the platform. The proximity dynamic beacon needs to be configured The number is large, and for the case where the protection zone selection range exceeds 4, due to the limitation of the track spacing, the project cannot arrange a sufficient number of proximity dynamic beacons to support the protection function of multiple protection zones
