2. Description of the Related Art In recent years, automatic ticket gates have become widespread mainly at transportation stations, but most of them are used to insert a ticket or commuter ticket into the ticket slot of the automatic ticket gate to carry out ticket gates.

It is configured by a battery 39 that supplies power to the.

That is, a data memory 37 is connected to the main controller 36, and the data memory 37 is connected to the data memory 37.
Various commuter pass data such as a unique ID code (unique data), usage section, and expiration date are registered (stored). The main controller 36 has a data control function, a data identification determination function, a communication control function, and the like, and
It has a data serial-to-parallel converter 35.

The serial-parallel converter 35 is connected to a modulator 34 which modulates the serial data sent from the main controller 36, and the modulator 34 is connected to the distributor / combiner 31. The distributor / combiner 31 is connected to the antenna 30 and the detector 38.

The starting circuit 32 is composed of, for example, a filter / amplifier circuit, a signal detecting circuit, a timer circuit, etc., and a pulse signal for a fixed time output from this circuit is input to the main control section 36. It is designed to start up.

4 to 7 are flow charts showing an example of the procedure of communication processing between the automatic ticket gate 1 and the commuter pass 8 constituting the gate system of the present embodiment. Hereinafter, referring to this flow chart, for example, A communication process when two commuter passes 8a and 8b are present in the communicable area 9 at substantially the same time will be described.

Data transmission / reception control section 13 of automatic ticket gate 1
After the power of this system is turned on,
The signal control unit 16 is driven to start the oscillation of the oscillator 24, the output high frequency signal is input to the modulator 22, and the regular time presented in the vicinity of the antenna 7 from the antenna 7 via the distributor / combiner 23. A high-frequency signal for activating the main control unit 36 in the commuter pass 8 is wirelessly emitted to the ticket 8 (S1).

At the start of this radio wave emission, the data transmission / reception control unit 13 of the wireless communication control unit 12 drives a timer to prompt the transmission of the ID code of the commuter pass 8 and periodically requests the ID code of the commuter pass 8. Therefore, the ENQ data is output to the parallel-serial converter 17 and converted into serial data. The converted serial data is input to the modulator 22, and the oscillator 2
The high frequency signal output from 4 is modulated, input to the distributor / combiner 23, and wirelessly transmitted from the antenna 7 connected thereto (S2). Then, the reception of the ID code from the commuter pass 8a or 8b is awaited (S3).

When the commuter passes 8a and 8b are presented at the same time in the communicable area 9 above the antenna 7, the commuter passes 8a and 8b receive the radio waves emitted from the antennas 7 by the respective antennas 30. Then, the wave is detected by the wave detector 38 via the distributor / combiner 31, and when a high-frequency signal of a certain level or higher is detected by the starting circuit 32, the main controller 36 is transmitted by transmitting a signal to the main controller 36. It is activated and operation is started (31).

The commuter passes 8a and 8b receive the ENQ data from the automatic ticket gate 1 through their respective antennas 30, demodulate them by the demodulator 33 via the distributor / combiner 31, and become serial data. The parallel converter 35 converts the data into parallel data, and the main controller 36 identifies the ENQ data (S32).

When the ENQ data is identified, the main control unit 36
Reads the ID code unique to the commuter pass from the data memory 37 and sends it to the serial-parallel converter 35 to convert it into serial data.

The converted serial data is sent to the modulator 34.
Receives the radio wave output from the automatic ticket gate 1 and uses it as a high frequency signal for modulation and distribution.
It is transmitted from the antenna 30 via the combiner 31 (S3
3).

When the commuter passes 8a, 8b detect a high-frequency signal and are activated as described above, the internal timer is operated to wait for ENQ data reception. Therefore, when ENQ data cannot be received, a time-out occurs. Will be stopped and the lock on the system is prevented.

The transmission data from the commuter passes 8a and 8b are output from each commuter pass at substantially the same time, resulting in interference. Therefore, the data transmission / reception control unit 13 of the automatic ticket gate 1 receives the interfering modulated radio waves transmitted from the commuter tickets 8a and 8b by the antenna 7, and cannot correctly identify the commuter ticket (the portion 120 in FIG. 8). ).

Therefore, conventionally, since the communication link cannot be identified, the communication link cannot be established and the processing cannot be performed. Therefore, in the present embodiment, in such a case, the automatic ticket gate 1
The data transmission / reception control unit 13 determines that the ID code of the commuter ticket cannot be correctly received due to interference, and the commuter tickets 8a, 8
For b, the specific data that defines the generation of the transmission timing for the ID code response and the transmission of the ID code at that timing, that is, the timing generation ID request data (hereinafter referred to as SSA data Yes) is transmitted from the antenna 7 (S4). Then, the waiting timer for reception is set, and the SSA transmission number counter (provided in the data transmission / reception control unit 13 and initially having a value of 0) is incremented.

The commuter passes 8a and 8b receive the SSA data from the respective antennas 30 (S34), and the main controller 3
When the SSA data is recognized in 6, the calculation logic is operated to generate the ID code transmission timing for the reply.

An example in which the ID code unique to the commuter pass is used as a factor in the calculation logic for the generation of the ID code transmission timing will be described below. FIG. 8 is a time chart showing an example of the ID code collision and recognition sequence, and FIG. 9 shows an example in which the ID codes of the commuter pass 8a and the commuter pass 8b are composed of N bits. is there.

A logical example of the timing calculation in this case is that when the main control unit 36 receives and recognizes the SSA data in the commuter passes 8a and 8b, the SSA reception counter (provided in the main control unit 36, Is 0),
The bits are sequentially shifted out from the LSB side of the ID code, and the transmission start timing is calculated and assigned by the shifted out bit data "1" and "0" (S3).
5). Then, the SSA reception counter is incremented.

The main control unit 36 transmits a unique ID code according to the assigned transmission timing (S).
36). At this time, if the shifted-out bit data of the commuter passes 8a and 8b are the same, the transmission timings are also the same, and interference will occur again. Therefore, the automatic ticket gate device 1 receives the above-mentioned interfering modulated radio waves transmitted from the commuter passes 8a and 8b at the antenna 7.
The commuter pass is not correctly recognized again (the portion denoted by reference numeral 121 in FIG. 8).

Therefore, the data transmission / reception control unit 13 of the automatic ticket gate apparatus 1 judges that the ID code of the commuter ticket cannot be received correctly due to interference, and the commuter ticket 8a, 8b
The transmission timing for the ID code response is generated, and the SSA data that defines the transmission of the ID code at that timing is transmitted from the antenna 7 (the portion 122 in FIG. 8).

This repeating sequence is repeated until the ID code is normally received (S5), the maximum number of times (S6), or a system error occurs (S7).

Data transmission / reception control unit 13 of automatic ticket gate 1
However, when the SSA data is repeatedly transmitted n times, the commuter passes 8a and 8b receive the SSA data from the respective antennas 30, and when the main control unit 36 recognizes the SSA data, the nth calculation logic operates. Then, the transmission timing for the reply is generated (the portion indicated by reference numeral 123 in FIG. 8).

In this embodiment, the bit data "1", which is shifted out, is sequentially shifted from the LSB side of the ID code according to the SSA reception counter.
The transmission start timing is calculated and assigned by "0" (S35). Then, the SSA reception counter is incremented. FIG. 10 shows an example of the transmission timing of this embodiment.

The main control section 36 transmits a unique ID code according to the assigned transmission timing (S).
36). At this time, if the shifted out bit data of the commuter passes 8a and 8b are different, the transmission timing is different and the transmission data does not interfere (the portion indicated by reference numeral 123 in FIG. 8).

Data transmission / reception control section 13 of automatic ticket gate 1
The antenna 7 sequentially receives the modulated radio waves transmitted from the commuter passes 8a and 8b and inputs them to the mixer 26 via the distributor / combiner 23. Distributor / synthesizer 23 and mixer 2
A signal obtained by modulating the signal from the oscillator 24 by the modulator 25 is input to 6 to perform asynchronous detection.

The demodulator 27 determines the base band of the detected signal and demodulates it into serial data. The demodulated serial data is converted into parallel data by the parallel-serial converter 17, and is recognized as the ID code of each of the commuter passes 8a and 8b identified by the data transmission / reception control unit 13 (S8). Then, the SSA transmission counter is cleared.

The data transmission / reception control unit 13 wirelessly transmits the ACK data, the unique ID code of the commuter ticket 8a, the unique ID code of the automatic ticket gate 1 and the like as transmission data as the recognized confirmation signal, and the commuter ticket 8a and A communication link between them is established (S15, S16).

The main control unit 36 of the commuter ticket 8a receives the above data from the automatic ticket gate apparatus 1 and determines that the automatic ticket gate apparatus 1 recognizes the data (S42). The ID code of the ticket 8a and the commuter ticket data such as the valid section and the valid period stored in the data memory 37 are wirelessly transmitted (S43, a portion 124 in FIG. 8). Then, the SSA reception counter is cleared.

On the other hand, the transmission data for establishing the communication link transmitted from the automatic ticket gate 1 is also received by the commuter pass 8b, but since it is not the unique ID code of the commuter pass 8b, the communication link is an automatic ticket gate. 1 is not established with the commuter pass 8b, a response to the received data is not transmitted, and communication interference does not occur.

Data transmission / reception control section 13 of automatic ticket gate 1
Receives the commuter pass data from the commuter pass 8a (S1
7) determine whether the data is valid or invalid (S1)
8). If the result of this determination is invalid, an abnormal process (S2
2) is performed to terminate the communication link with the commuter pass 8a.

Then, the data transmission / reception control unit 13 sends the ACK data, the unique ID code of the commuter ticket 8b, the unique ID code of the automatic ticket gate 1, etc. as the recognized confirmation signal to the commuter ticket 8b. Wirelessly send as
A communication link with the commuter pass 8b is established (S2).
3, S24, S16, S17).

If the commuter ticket data from the commuter ticket 8a is valid, the data transmission / reception control unit 13 performs internal processing (S19, S20), and the ID code of the commuter ticket 8a,
The ID code of the automatic ticket gate 1, the unique data of the processed automatic ticket gate 1, the processing date and time, the status data such as entry or exit are wirelessly transmitted (S21).

When the main control unit 36 of the commuter pass 8a receives the above-mentioned status data from the automatic ticket gate 1 (S44), it writes necessary data in the data memory 37,
When that is completed (S45), the ID code of the automatic ticket gate 1, the ID code of the commuter pass 8a, and the processing completion data are transmitted (S46).

Data transmission / reception control section 13 of automatic ticket gate 1
Receives the above data from the commuter pass 8a (S2
5) It is determined that the communication is normally completed, and to that effect is transmitted to the gate main control unit 10 (S26), and the ID of the commuter pass 8a is obtained.
The code, the ID code of the automatic ticket gate 1, and the processing completion data are transmitted, and the communication link is closed and released (S27).

Then, it is checked whether or not there is another commuter pass that can be identified (S28). As a result of this check,
If there is another commuter pass that can be identified, a communication link is established (S15), and communication processing is similarly performed. If there is no other commuter pass that can be identified, the process jumps to the activation signal transmission routine for another commuter pass. Then, the ENQ data is periodically transmitted (S2), and a standby loop for checking the presence or absence of a response signal from the commuter pass is performed (S3).

Next, a communication process when, for example, three commuter passes 8a, 8b, 8c simultaneously exist in the communicable area 9 will be described. The process of identifying one commuter pass and detecting the interference of two commuter passes is the same up to the process of separating and identifying the two commuter passes (S8). In that process (S8),
Only one commuter pass was identified, so commuter pass 8
One correct ID code, which is a, and commuter passes 8b and 8c
The data transmission / reception control unit 13 of the automatic ticket gate 1 obtains the two sections of the unidentified error data of the interference (see FIG. 9).

Of the two types, the automatic ticket gate 1 designates the identified ID code for the commuter pass 8a whose ID code is identified, and stops the SSA function response for stopping the response of the SSA function. Send data (S
9).

When the main control unit 36 of the commuter pass 8a receives the SSA function response stop data from the automatic ticket gate 1 (S
37), stop the response of the SSA function, and transmit the response of the SSA function response stop acceptance (S38).

Data transmission / reception control unit 13 of automatic ticket gate 1
When receiving the response to the SSA function response stop acceptance from the commuter pass 8a, it confirms it (S10), and then continues to the SS for the two commuter passes 8b and 8c which cannot be separated.
A data is transmitted (S11).

Then, the transmission timing of the ID code is different at the kth time (see FIG. 9), and the data transmission / reception control unit 13 of the automatic ticket gate 1 can recognize the ID code of the commuter passes 8b and 8c (S12).

The calculation logic (shift bit number, timing time) for generating the transmission timing can be changed by using several kinds of SSA data codes or by attaching auxiliary codes. Further, in the present embodiment, the explanation has been made with the 1-bit shift, but it goes without saying that the shift may be carried out by several bits.

As described above, according to the above embodiment,
By using the logic to calculate the transmission timing for the response from the automatic ticket gate between the automatic ticket gate and the commuter ticket, the automatic ticket gate can ensure that the timing is different between multiple commuter tickets. Therefore, the ID code unique to the commuter pass can be obtained.

Therefore, even if the user possesses a plurality of commuter passes and presents a plurality of commuter passes in the communicable area, the automatic ticket gate and the adaptive commuter pass can be surely communicated. And processing based on data transmission / reception can be performed.

In the above embodiment, the automatic ticket gate apparatus additionally transmits the shift bit number of the unique ID code as the auxiliary data code in the specific command for generating the ID code transmission timing to be transmitted to the commuter pass. Thus, the number of shifts at the time of reception may be obtained without using the SSA counter for the commuter pass or maintaining the previous shift state.

Further, in the above-mentioned embodiment, the communication process with each commuter ticket is performed after recognizing all or as much as possible the ID code of the commuter ticket, but the ID code of the commuter ticket is determined. It is also possible to carry out the communication process from 1) to continue to identify the ID code of the commuter pass that has not been identified after the process with one commuter pass is completed.

Furthermore, in the above embodiment, the case where the gate device is the automatic ticket gate device and the recording medium is the commuter ticket has been described, but the present invention is not limited to this. It may be a ticket or the like, or the gate device may be a check device for checking entrance and exit to a facility such as a theater or an amusement park, and the recording medium may be tickets for entering and exiting.

[0067]

As described above in detail, according to the present invention, even if the user has a plurality of recording media and presents these recording media in the communicable area, the interference or the communication is caused. It is possible to provide a gate system that can reliably perform separation communication between a gate device and an adaptive medium without causing a defect and can normally perform processing based on data transmission and reception.
