Abstract: An antenna filter unit and a base station having the antenna filter unit are disclosed. The antenna filter unit according to an embodiment comprises a dielectric body that defines a plurality of single-mode resonators each including a tuning hole. At least one slot is formed on a surface of the dielectric body to serve as an antenna radiator. The at least one slot is coupled to at least one of the resonators.

Abstract: The present invention relates to a contactless intelligent customer-service system applied to rail transit and an application method thereof. The system includes: an intelligent customer-service platform server, an intelligent customer-service interface server, a system switch, a station maintenance workstation, and an intelligent passenger service terminal, where the system switch is connected to each of the intelligent customer-service platform server, the intelligent customer-service interface server, the station maintenance workstation, and the intelligent passenger service terminal; and the intelligent passenger service terminal provides, through AI interaction and intelligent speech, a passenger with intelligent services that include information inquiry and display of various facilities inside a station, information inquiry of convenient surrounding facilities, information inquiry of a train operation status, and emergency help.

Abstract: An intelligent dispatching method and system for rail transit. The method includes: collecting original data of a preset range from a plurality of data sources; acquiring passenger flow data of a rail transit station according to the original data; building a passenger flow prediction model of the rail transit station according to the passenger flow data of the rail transit station; acquiring a passenger flow volume of the rail transit station in a preset period according to the passenger flow prediction model; and performing coordinated dispatching on vehicles and passengers of the rail transit station according to the passenger flow volume of the preset period. The original data is acquired through the plurality of data sources, thus acquiring the passenger flow data, which achieves all-round monitoring of a passenger flow at the rail transit station.
