Autonomous Decentralized High-Speed Processing Technology and the Application in an Integrated IC Card Fixed-Line and Wireless System

There is Processing speed improvement of the automatic fare collection gate (AFC gate) as one of the important problems to correspond to the passengers getting on and off in high density transportation at the peak. On the other hand, reliability is indispensable to handle the ticket that is the note. Therefore, the ticket system that has both high-speed and high reliability is necessary and indispensable. For the passenger's convenience improvement and maintenance cost reduction, wireless ticket system is hoped. However, the high-speed and the high reliability are ambivalent at this system because of wireless communications between an and an gate; the faster the gate processes the ticket, the poorer the reliability gets. In this thesis, it proposes the autonomous decentralized to meet high-speed in wireless ticket system and the requirement of high reliability. IC card and Central server are assumed to be an autonomous system. It proposes Decentralized algorithm of the fare calculation by and the AFC to achieve high-speed processing. Moreover, Autonomous, decentralized consistency technology in each subsystem is shown for high-reliability. In addition, to make these the effective one, Wireless communication area enhancing (touch & going method) and Command system for the data high speed processing are shown. These technologies are introduced into the Suica system of East Japan Railway and the effectiveness has been proven.
