Embodiment 1

[0016] Embodiment one, refer to figure 1 As shown, the unmanned train short-distance relocation system includes several beacons arranged along the extension direction of the ground track and two beacon readers installed on the train, and the two beacon readers read the beacons in sequence Complete the security positioning.

[0017] Among them, two adjacent beacons have a difference distance and the difference distance needs to be greater than twice the reading side lobe of the beacon plus the distance traveled by the train within the reading delay time to ensure the reading order of the two beacons. The value is 0.6m ~ 1m. When the distance is less than this distance, the system may acquire two beacons at the same time, and it will be impossible to judge the direction of the train based on the positioning principle.

[0018] In this embodiment, the two beacon readers are respectively arranged at the front and rear of the train. Of course, those skilled in the art can unders...

Abstract

The invention discloses a short-distance repositioning system of an unmanned train. The system includes a plurality of beacons arranged along the extending direction of the ground track and two beaconreaders arranged on the train, the adjacent two beacons have a difference distance and the difference distance needs to be greater than twice the distance of the beacon reading sidelobe plus the train passing in the reading information delay time. The double beacon differential arrangement, and a short-range positioning technology scheme in which the double beacon reader reads the beacons in short-range order are adopted, so that the vehicle-mounted equipment can continuously read two beacons in a short range, thereby completing positioning.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a vehicle-mounted signaling system. Background technique [0002] The traditional vehicle signal system needs to read two beacons (or transponders) continuously to complete the safe positioning. Generally, one reader continuously reads two beacons to complete safe positioning. Since the transmitter power of the reader and the radiation range of the beacon need to be independent of each other, it generally takes 3m to 5m to complete the positioning. [0003] The existing initial positioning method in which a single reader continuously reads two beacons cannot meet the needs of unmanned driving to wake up on-site positioning after power-on. The current initial positioning technology based on long transponders and loop transponders used for unmanned driving power-on wake-up is essentially to locate after reading a beacon, which requires ground ATP assistance to co...
