Design and Implementation ATM communication e-pay using PSTN / leased line

PSTN을 이용한 비동기 방식의 프로토콜 설계와 구현

The increase of vehicles stagnations leads to the increasing attention to the way customers pay and a large number of projects on electronic cash system. Transport system is comprised of a number of advanced technologies, including information processing, communications, control, and electronics. Recently many research on a system which provides contact in order to protect driver's vehicle passage have been carried out. And some potential problems from that system are being reviewed by electronic cash system. In this papers, we suggest RF protocol developing technology using the concept of electronic cash. ATM electronic cash developing is consist of component of pre-developed coin throw, integration of component using its, and production of more requirement-satisfactory ITS solution. Result increase 15∼40% pre-type vehicles stagnations. Especially, we expect this proposed concept would be well adapted to our national environments.
