[0002] The automatic fare collection (AFC) system in the rail transit station hall includes ground-based ticket machines, ticket booths, entry and exit gates, and equipment rooms. Currently, all equipment is routed from below, which means that the cable ducts can only be installed in the decoration layer below the floor tiles in the station hall.
[0003] However, the decoration layer is connected to the entire civil structure. If the civil structure leaks, water will penetrate into the cable duct through the structure, causing the AFC system cables to be soaked and affecting the equipment quality. In order to ensure the safety of subway equipment, the cables need to be laid in the cable duct, led out from the ceiling of the station equipment area to the station hall, and introduced into the station hall floor from the pillars. Because the pillars and the station hall floor are at a vertical angle and there is a circle of ditch around the pillars, this vertical corner requires special treatment. However, the current rail transit AFC system wiring is all from the machine room through the ground decoration layer to the bottom of the equipment in the station hall. The connection between the top and bottom of the station hall has not been studied in depth, and there is no precedent to learn from. Utility Model Content
