The present invention relates to an inter-car wireless connector, and more particularly, to a wireless connector which can replace an existing inter-car connector by receiving and transmitting railcar signals by using a Bluetooth transmitter. In an embodiment of the present invention, an inter-car wireless connector is installed in each of the adjacent railcars, which will become a master or a slave depending on the moving direction of the car. The wireless connector features a Bluetooth transmitter which converts signals between adjacent railcars into wireless signals and transmits the converted wireless signals from the master to the slave in a unidirectional way. The Bluetooth transmitter comprises: an automatic paring part which allows Bluetooth transmitters in adjacent railcars to register each other as a pair; a master/slave converting part which identifies the moving direction of a railcar based on information on the moving direction contained in the car signals and selects the Bluetooth transmitter installed in the preceding railcar as the slave and the Bluetooth transmitter installed in the following railcar as the master; and a wireless communication part which transmits wireless railcar signals from the master to the slave in a unidirectional Bluetooth communication system.
본 발명은 철도차량의 차간 무선 연결기에 관한 것으로서, 더욱 상세하게는 종래 차간 연결기를 대체하여 블루투스 송수신기로 차량 간에 차량신호를 송수신하는 무선 연결기에 관한 것이다. 본 발명의 실시예에 따른 철도차량의 차간 무선 연결기는, 철도차량의 각 차량 앞뒤에 설치되는 것으로, 차량의 진행방향에 따라 하나는 주(Master)가 되고 다른 하나는 부(Slave)가 되어, 인접된 차량 간 차량신호를 무선신호로 변환하여 블루투스 단방향 통신으로 상기 주(Master)에서 부(Slave)로 송신하는 블루투스 송수신기를 구비한다.
