연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A system and method which can detect the presence of a vehicle within the protected area of a four gate railroad crossing, determine its location and direction it is moving in, and open an appropriate exit gate to allow the vehicle to escape prior to the arrival of a train at the crossing. The system has a series of magnetometer sensors suitably placed in the crossing to detect the presence of a vehicle. The sensors are connected to a controller which analyzes readings from the sensors. Upon the approach of a train, the controller, based on analysis of r...

청구항

[We claim:] [1.]receiving a signal that a train is approaching the crossing;commencing sampling of readings from sensors located at the crossing;analyzing the readings from the sensors to determine if and when the crossing is clear so that exit gates to the crossing can be lowered;generating an all clear signal when it is determined that the crossing is free of any vehicular traffic; andlowering into place crossing exit gates.
