DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION This invention is installed in a railway station or the like, by transmitting and receiving data in the media and radio, such as a periodic ticket, traffic
The present invention relates to an automatic ticket gate and a non-contact pass gate system for determining whether or not to perform a pass.

[0002]

2. Description of the Related Art In recent years, data has been transmitted and received wirelessly between a gate device and a medium in consideration of improvement in operability of a user when passing through a gate, and it is determined whether or not the vehicle can pass based on the obtained data. A non-contact pass gate system as described above has been proposed. Such a non-contact pass gate system can be used for ticket gate processing at a station, entry / exit management of a building, customer management at a store, and the like.

However, in the non-contact pass gate system, a communication range between the medium possessed by the user and the gate is set to a range of about 10 cm to 3 m. May be presented. In such a case, data interference occurs at the gate, and wireless transmission and reception with the medium are all disabled.

Therefore, for example, in Japanese Unexamined Patent Application Publication No. Hei 3-21096, when a plurality of media enter the communicable area of the gate, the media that has entered later is communicating with the media that has entered first and the gate. By not detecting the communication signal until the communication is completed, the gate sequentially executes the communication process for each of the plurality of media that have entered the communicable area.

[0005]

However, in the conventional non-contact pass gate system described above, when a plurality of users present their respective media in the communicable area, the invasion time of each medium into the communicable area always increases. This is done by focusing on the difference. For this reason, if one user stores a plurality of different types of media in the same case, the plurality of media will simultaneously enter the communicable area, and from a plurality of media simultaneously. Communication signals are transmitted, interference occurs at the gate, and data transmission and reception are all disabled.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic conversion system capable of accurately transmitting and receiving data to and from a plurality of types of media even when the media are simultaneously presented in a communicable area.
An object of the present invention is to provide a billing machine and a contactless pass gate system.

[0007]

[0008]

[0009]

A non-contact pass gate system according to the present invention wirelessly transmits and receives data between a plurality of types of media and a gate, and requests the gate to transmit data to the plurality of types of media. In a non-contact pass gate system that transmits a reception command to perform a pass / fail decision based on data transmitted from any of the media, the reception command is received in the medium, and the reception command is set in advance for each type of medium. Transmission waiting means for transmitting data after the communication waiting time has elapsed.

[0010] Further, in the non-contact pass gate system according to the present invention, in the above configuration, the reception command may include:
A communication waiting time corresponding to each of a plurality of types of media is included.

[0011]

[0012]

[0013]

[0014]

According to the present invention, a communication waiting time unique to the medium is set in advance for each of a plurality of types of media, and after receiving the reception command, the data is transmitted from the medium after the communication waiting time has elapsed.

Further , in the present invention, from the gate,
An acceptance command including a communication waiting time corresponding to each of a plurality of types of media is transmitted.

[0024] FIG 6 is a flowchart showing the automatic ticket gate, a procedure of data transmission and reception control unit which medium has to transmit and receive data in this automatic ticket machine by wireless. The data transmission / reception control unit 21 of the automatic ticket gate 1 sets 1 to a counter i (n1). This counter i specifies the identification data to be added to the reception command from among the plurality of identification data shown in FIG. Next, the data transmission / reception control unit 21 reads the i-th identification data corresponding to the content of the counter i (n2), and transmits a reception command with the identification data added to the medium (n3). When the medium that has entered the communicable area formed above the antenna 2 of the automatic ticket gate 1 receives the reception command to which the identification data has been added (n15), the data transmission / reception control unit 31 of the medium adds the reception command to the reception command. The identified identification data is determined (n16).
If the identification data matches its own identification data in n16 (n17), the medium transmits response data to the automatic ticket gate 1 (n18). When receiving the response data transmitted from the medium (n4), the data transmission / reception control unit 21 of the automatic ticket gate 1 checks the received data (n5). As a result of the verification, if the received data is normal (n6), the data transmission / reception control unit 21 transmits a gate opening command to the main control unit that controls the gate opening / closing device (n7).

If no response data is received from the medium at n4, the data transmission / reception control unit 21 of the automatic ticket gate 1 adds 1 to the counter i (n8).
The processing after n1 is repeatedly executed. When the response data is not transmitted from the medium after transmitting the reception command to which the k-th identification data is added, the data transmission / reception control unit 21 determines that the passerby does not have a medium usable in the automatic ticket gate 1. Judgment is made and a gate closing command is transmitted to the main controller (n9, n10). n7 or n
