JPH04241084A - Automatic ticket examination system using non-contact card - Google Patents

Abstract

PURPOSE:To prevent data from getting entangled by dividing the storage part of a non-contact card into plural recording areas, storing a data for judging the possibility of getting on a train for each electric railroad company and transmitting the data in the storage area corresponding to an electric railroad company identification data transmitted from a ticket examination machine. CONSTITUTION:An EEPROM 15 stores the data for judging the possibility of getting on the train. This EEPROM 15 is divided into plural memory areas MA1-MAn, and the data for judging the possibility of getting on the trains for the respective electric railroad companies are written in the respective memory areas. The leading data in each memory area is defined as an ID code for each company which is the electric railroad company identification data. A transmission/reception control circuit 16 exchanges the data with the ticket examination machine through an antenna 2. A power supply circuit 17 for electromagnetic force extracts power caused by electromagnetic force from this transmission/reception control circuit 16 and supplies the power to a CPU 11 or the like.

Description

[Detailed description of the invention]

0001

[Field of Industrial Application] This invention relates to an automatic ticket gate system applied at ticket gates of railway stations, etc., and in particular, the present invention is comprised of a contactless card and a ticket gate that transmits and receives data between the contactless card. Regarding automatic ticket gate system.

0002

[Prior Art] Automatic ticket gate systems installed at train station ticket gates, etc. have traditionally been equipped with a ticket gate having an insertion slot for a magnetic card carried by a passenger, and the magnetic card inserted into the ticket gate is contacted. The data is read through a magnetic head and a determination is made as to whether or not the vehicle can be ridden. However, with such conventional automatic ticket gate systems using magnetic cards, the magnetic card must be removed from a passenger compartment and inserted into the slot of the ticket gate, making this operation difficult if there is baggage. It is cumbersome and hinders the smooth flow of passengers through the ticket gate. Therefore, we use a contactless card that transmits and receives data to and from the ticket gate as a card that passengers carry.
An automatic ticket gate system using a contactless card that stores data such as card balance and user attributes and is used as a commuter pass or prepaid card has been proposed.

0003

[Problem to be solved by the invention] However, in the automatic ticket gate system using the above-mentioned contactless card, data is sent and received between the card carried by the passenger and the ticket gate, so it is difficult for each railway company to do so. However, if you use multiple railway companies for transit rides, etc., you will need to carry multiple cards. When a user carrying multiple such contactless cards passes through a ticket gate, data may be transmitted from the multiple cards in response to commands from the ticket gate, and the data transmitted from the cards may be A problem arises in which necessary data cannot be read at the ticket gate due to crosstalk.

The object of the present invention is to divide the storage section of the contactless card into a plurality of storage areas for each electric railway company, store data for determining whether or not to board the train for each electric railway company in each storage area, and Only the data in the storage area corresponding to the ticket gate being used will be sent from the contactless card, so even when using multiple railway companies for transfers, etc., you only need to carry one contactless card. An object of the present invention is to provide an automatic ticket gate system using a contactless card that can prevent data mix-up at the ticket gate by transmitting only data suitable for the ticket gate through which it passes.

[0005]

[Means for Solving the Problems] The automatic ticket gate system using a contactless card of the present invention has an automatic ticket gate system that uses a contactless card that stores data for determining whether or not to board a vehicle in its storage section, and a presented contactless card. In an automatic ticket gate system consisting of a ticket gate that sends and receives data and determines whether boarding is allowed based on the received data, the storage section of the contactless card is divided into a plurality of storage areas, and each storage area is The present invention is characterized by comprising a storage area selection means for storing data for determining whether or not to board the train for each electric railway company and transmitting data of a storage area corresponding to electric railway company identification data transmitted from a ticket gate.

[0006]

[Operation] In this invention, the storage section of the contactless card that sends and receives data to and from the ticket gate is divided into multiple storage areas, and each storage area stores data for determining boarding permission for each railway company. be done. When a user presents a contactless card when passing through a ticket gate, the ticket gate transmits railway company identification data to the contactless card.

[0007] When the contactless card receives the electric railway company identification data, the storage area selection means transmits the data stored in the storage area corresponding to the electric railway company identification data to the ticket gate. Therefore, a single contactless card stores boarding permission determination data for multiple electric railway companies, and selects the data to be transmitted depending on the ticket gate through which the card is used. data can be sent to the ticket gate.
