In addition, if the difference between the current time and the supplied processing time is equal to or less than a predetermined time, the current passage availability determination processing is stopped.
Therefore, the determination as to whether or not data transmission / reception processing has been performed between the same storage medium and another transmission / reception means within a predetermined time is executed only for the adjacent transmission / reception means.

In the invention described in claim 6, the transmission / reception means executing the data transmission / reception processing with the storage medium transmits
Data on the storage medium is supplied to the transmission / reception means corresponding to the adjacent passage. When data on a storage medium on which data transmission / reception processing is being performed is supplied from an adjacent transmission / reception means, the data transmission / reception processing on the storage medium is restricted by the processing restriction means . The treatment regulation means
For example, data from the transmitting and receiving means corresponding to the adjacent passage
Data about the storage medium that is performing transmission / reception processing is supplied.
When the storage medium is
Do not execute. Therefore, when the same storage medium is presented in the communicable area of the plurality of transmitting / receiving units corresponding to the adjacent passages, the transmissibility determination is not performed by the subsequently presented transmitting / receiving unit.

According to a seventh aspect of the present invention, the processing in the storage medium or the gate device according to the third, fifth, or sixth aspect of the present invention is performed in such a manner that the processing is performed in a direction opposite to the installation side of the transmission / reception means and the installation side of the transmission / reception means. And only in the opposite direction. Therefore, processing is performed only on the transmission / reception means of another passage close to the transmission / reception means corresponding to one passage, and the frequency of execution of the processing is reduced.

In the invention described in claim 8, the transmitting / receiving means which has started transmitting / receiving data to / from the storage medium is the transmitting / receiving means corresponding to the same-directional passage adjacent to the side opposite to the installation side of the transmitting / receiving means. When the data processing is started within a predetermined time, the data transmission / reception means corresponding to the adjacent path is requested to cancel the data processing. Therefore, even if the storage medium is presented first to the transmission / reception means of the passage adjacent to the passage to which the passer intends to pass, the passability determination is performed only in the transmission / reception means corresponding to the appropriate passage.

According to the ninth aspect of the present invention, the number of times of passage permission processing in each passage is compared with the number of passages of passers-by, and when data processing for the same storage medium is executed in an adjacent passage, When the number of times of passage permission processing exceeds the number of passages of passers-by, the number of passage permission times is decremented. Accordingly, the traffic determination is performed in a plurality of passages which are adjacent to the same storage medium, if the traffic in the traffic determination processing previously is permitted, the gate already after if the passer is passed through the passage Passing through the passage where the process has been started is prohibited, and if a passerby has not yet passed through the passage on which the gate process has been executed first, passage through that passage is prohibited.

FIG. 4 is a flowchart showing a processing procedure of the control unit of the automatic ticket gate according to the embodiment of the present invention. The CPU 2 included in each of the automatic ticket gates 1a and 1b transmits a reception command at regular time intervals (n1) and waits for reception of a response from the storage medium 21 such as a commuter pass (n2). CPU2 in waiting for the reception of this response, it is checked whether the input of the reception inhibiting command from the other direction of the automatic ticket gate (n3).
Upon receiving a response from the storage medium 21 and outputs the reception inhibition instruction to the other direction of the automatic ticket gate (n4). Thereafter, the data for the passage permission / inhibition determination included in the response is collated (n5), and the gate is opened and closed according to the collation result (n6 to n8). Thereafter, wait for exiting the passer from the inside passage 31 (n9), and outputs an instruction for canceling the acceptance prohibition against the passerby from the passageway 31 exits the other direction of the automatic ticket gate (n10).

The CPU2 in while waiting for reception of response data from the storage medium (n1 to n3), the rejection command from other <br/> Direction of automatic ticket gate is input, rejection release The transmission of the reception command is stopped until the command is input (n11). Therefore, when one of the automatic ticket gates 1a or 1b starts transmitting / receiving data to / from a storage medium carried by a passerby trying to pass in the X direction or the Y direction with respect to the passage 31, automatic ticket gate 1b, 1a can be prevented by stopping the transmission of the received commands until exiting passage 3 1 or et passerby is passer simultaneously in both directions in a single passage 31 that enters in advance .

FIG. 5 is a schematic plan view of an automatic ticket gate to which the embodiment of the invention described in claim 2 is applied. The automatic ticket gates 1a, 1b installed with their backs in contact with each other constitute passageways 31a, 31b, respectively. Automatic ticket gate 1

The automatic ticket gate 1b transmits and receives data to and from a storage medium presented by a passerby passing in the arrow Y direction through the passage 31b via the antenna 14b.

FIG. 6 is a flowchart showing a processing procedure of the control unit of the storage medium applied in the embodiment of the present invention. The CPU 22 of the storage medium 21 waits for reception of an acceptance command transmitted from the automatic ticket gates 1a and 1b (n21). When the reception command is received, RA
The previous data transmission / reception time Tr stored in M24 is read (n22). The storage time Tr is compared with the reception time Ta indicating the time at which the current reception command was executed (n23). The reception time Ta is set at the automatic ticket gates 1a and 1b.
It is included in the reception command transmitted from. Note that a timer may be provided in the storage medium 21 to read the time measured by the timer when receiving the reception command.

In the comparison between the storage time Tr and the reception time Ta, if the difference between them exceeds a predetermined time k, the EEPR
The data for judging passage permission stored in the OM 26 is read (n25), and transmitted to the automatic ticket gates 1a and 1b as response data (n26). Thereafter, the current reception time Ta is written to a predetermined memory area of the RAM 24 as the storage time Tr (n27).

The storage time Tr and the reception time T at n24
If the difference between the two is smaller than the predetermined time k, the response data is not transmitted. As the fixed time k, for example, a time of about 5 seconds is set. In the automatic ticket gates 1a and 1b shown in FIG. 5, a passerby who has entered the passage 31a in the direction of the arrow X is the antenna 14a of the automatic ticket gate 1a.
When the storage medium is presented to the antenna 14b of the adjacent automatic ticket gate 1b after the storage medium is presented to the automatic ticket gate 1b, the automatic ticket gate 1b determines whether or not there is a passerby in the passage 31b. Perform processing. Such a situation may occur when a passerby presenting the storage medium to the antenna 14a stores the storage medium in a bag or pocket.

In this embodiment, in the above situation, the storage medium 21 carried by the passerby passing in the direction of the arrow X in the passage 31a transmits and receives data to and from the automatic ticket gate 1a via the antenna 14a. After that, when the storage medium 21 is presented in the communicable area of the antenna 14b while passing through the passage 31a, the storage medium 21 receiving the reception command from the antenna 14b transmits the response data to the automatic ticket gate 1b. The automatic ticket gate 1b does not perform a pass / fail determination process for a storage medium carried by a passerby passing through another adjacent passage 31a, so that malfunction of the automatic ticket gate is prevented beforehand. Is done. In addition,
The reception commands transmitted by the automatic ticket gates 1a and 1b include a path number for specifying the path constituted by the automatic ticket gates, and store the path number in the storage medium at the storage time T
The reception time Ta and the storage time Tr may be stored only when the path number included in the reception command received this time is adjacent to the path number related to the previous data processing. With this configuration, the processing time in the storage medium can be reduced.

FIG. 7 is a flowchart showing the processing procedure of the control unit of the automatic ticket gate that constitutes the embodiment of the non-contact pass gate system according to the fourth aspect of the present invention. FIG.
The CPU 2 included in the automatic ticket gates 1a and 1b installed as shown in (1) transmits an acceptance command at a predetermined timing and waits for transmission of a response from the storage medium 21 (n31, n32). When the response data transmitted from the storage medium 21 is received, the current time Tn measured by the timer 8 is read (n33). Next, the processing time Ts included in the response data transmitted from the storage medium 21 is compared with the current time Tn (n34).
The processing time Ts is the processing time of the previous data transmission / reception in the storage medium 21. The processing time Ts is read out from a timer provided in the storage medium 21 itself, or the current time data included in the reception command transmitted from the automatic ticket gates 1a and 1b. It is stored as the processing time Ts. The storage medium 21 transmits the processing time Ts to the automatic ticket gates 1a and 1b together with the data relating to the passability determination.

If the difference between the current time Tn and the processing time Ts is equal to or longer than the predetermined time k, the data for judging whether or not the traffic is transmitted from the storage medium 21 is collated (n35, n36). The gate is opened / closed according to the propriety of the data for judging whether or not traffic is possible (n37 to n40).

If the difference between the current time Tn and the processing time Ts is smaller than the predetermined time k, the processing relating to the passage permission / prohibition determination is not executed (n35 → n31). Therefore, for the storage medium for which the passability judgment processing has been properly completed in one of the automatic ticket gates shown in FIG. 5, the passability judgment processing is not performed in the automatic ticket gates constituting the adjacent passage, and the passage in the passage is not performed. A malfunction does not occur in an automatic ticket gate to which no one passes.

FIG. 8 is a flowchart showing a processing procedure of the control unit of the gate device constituting the non-contact pass gate system according to the fifth embodiment of the present invention. CP
U2 transmits the reception command at a certain timing (n
41), waiting for transmission of response data from the storage medium 21 or input of processing data from an adjacent gate device (n42, n43). When processing data is input from an adjacent gate device, it is stored in a predetermined memory area of the RAM 4. The processing data includes an identification code of a storage medium related to the data processing executed in the adjacent gate device and data indicating a processing time. Upon receiving the response data transmitted from the storage medium 21 during the standby, the CPU 2 reads the processing data stored in the RAM 4 (n42 → n45), and identifies the identification data of the storage medium 21 included in the received response data, It is determined whether the data matches the identification data included in the processing data (n
46). If the identification data included in the response data and the identification data included in the processing data do not match, the data related to the passage permission / inhibition determination is collated, and the gate opening / closing process is performed according to the collation result (n47 to n47). n5
1). When the data is properly collated in the passage permission / inhibition determination processing, the identification data and the processing time of the storage medium that has performed the passage permission / inhibition determination processing are output to the adjacent gate device (n52).

On the other hand, when the identification data included in the response matches the identification data included in the processing data supplied from the adjacent gate device at n46,
The current time Tn is compared with the processing time Ts included in the processing data (n53). In this comparison, if the time difference between the current time Tn and the processing time Ts is equal to or longer than the predetermined time k, the flow proceeds to n47 to execute the passage permission / inhibition determination process. Also,
If the difference between the two times is less than the fixed time k, it is determined whether or not traffic is possible
It does not execute the process according to the (n54 → n 41).

According to the above-described processing, after the storage medium carried by the passer who has passed through one of the plurality of adjacent paths is presented to the gate device corresponding to the path, the storage medium erroneously identified as the adjacent path. When presented to the constituent gates, the identification data included in the response data read by the adjacent gate device is the identification data of the storage medium related to the passability determination process performed by the gate device that the passer has passed. Matches. At the same time, since the data itself from the storage medium in the two paths continuously occurs within a certain time, the current time Tn and the processing time Ts
Both are similar in comparison with. Therefore, since the passing row determination process in the adjacent gate device is not performed, there is no causing a malfunction of the gate in adjacent passages.

FIG. 9 is a flow chart showing the processing procedure of the control unit of the non-contact pass gate system according to the sixth embodiment of the present invention. The CPU 2 also waits for input of identification data from an adjacent gate device while waiting for reception of a response from the storage medium, and transmits a reception command at a predetermined timing during this period (n61 to n61).
n63). When the identification data of the storage medium for which the passage permission / inhibition determination process has been completed is input from an adjacent gate device, the identification data is transmitted to R.
It is stored in a predetermined memory area of AM4 (n64).

When receiving the response transmitted from the storage medium, the CPU 2 reads the identification data stored in the RAM 4 (n65) and compares this with the identification data included in the response data (n66). If the identification data stored in the RAM 4 and the identification data included in the response data do not match, a collation process is performed based on the data for determining whether or not traffic is permitted included in the response data. The gate is opened and closed (n67 to n72). If the data is appropriate in the passability determination processing,
Output the processing end data to the adjacent gate device (n7
3).

On the other hand, if the identification data included in the response data matches the identification data stored in the RAM 4 at n66, it is determined whether there is processing end data from an adjacent gate device (n74), and the adjacent gate device is determined. RAM when processing end data is input from the gate device
4 is erased (n75).

When a plurality of adjacent passages are formed by the above-described processing, the passage permission / inhibition determination processing may be performed in the adjacent passages for the storage medium on which the passage permission / inhibition determination processing is being performed in one of the passages. Absent.

In the gate device constituting the non-contact pass gate system according to the third, fifth or sixth embodiment of the present invention, the adjoining passage has a direction opposite to the installation side of the transmitting / receiving means of the gate device. it is possible to reduce the occurrence frequency of the input and output processing of the gate between adjacent gate device as a whole by limiting the same direction of the passage of the installation side opposite the passage and the transmitting and receiving means. As described above, the present invention is particularly applicable to the passage in the opposite direction to the installation side of the antenna and the passage in the same direction opposite to the installation side.
The reason for this is that in such a case, the antennas of the gate devices constituting the adjacent passage approach each other, and erroneous detection is likely to occur.

FIG. 10 is a schematic plan view of a gate device constituting a non-contact pass gate system according to an embodiment of the present invention. As shown in FIG.
Adjacent passages 31a and 31b in the X direction are formed by a and 1b. In the gate device thus configured, the storage medium carried by the passerby passing through the passage 31a is presented in the communicable area of the antenna 14b of the adjacent passage 31b, and then the antenna 14a of the gate device 1a constituting the passage 31a May be presented in the communicable area. Even in such a case, the gate device 1b malfunctions.

FIG. 11 is a flowchart showing a processing procedure of the gate device constituting the non-contact pass gate system according to the embodiment of the present invention. The CPU of the gate device 1a or 1b transmits an acceptance command at a fixed time interval in the idling state, waits for reception of response data transmitted from the storage medium, and performs processing from the adjacent gate device 1b or 1a. It waits for data input (n81 to 83). When processing data is input from an adjacent gate device, a timer T for measuring a certain time is started (n84), and identification data of a storage medium included in the processing data is stored in a predetermined memory area of the RAM 4 (n85). .

When the response data transmitted from the storage medium is received, it is determined whether the identification data included in the response data matches the identification data stored in the RAM 4 (n86). It is determined whether T has timed out (n87). If the timer T has not expired, a command to cancel the passage permission / inhibition determination process is output to the adjacent gate device (n88).

Thereafter, the data for passability determination included in the response data is collated, and the gate is opened and closed according to the collation result (n89 to n93). Upon completion of the passage permission / inhibition determination processing, the storage medium identification data relating to the passage permission / inhibition determination processing is output to the adjacent gate device (n9).
4).

As described above, the storage medium carried by the pedestrian passing through one of the adjacent passages in the same direction transmits and receives data to and from the antenna of the gate device constituting the adjacent passage. When the passage permission / inhibition determination process is performed in the gate device, it is possible to prevent a malfunction in the gate device that constitutes a passage through which a pedestrian does not pass.

FIG. 12 is a flowchart showing a processing procedure of the gate device constituting the non-contact pass gate system according to the embodiment of the present invention. CPU2
Sends a reception command at fixed time intervals,
It waits for transmission of response data from the storage medium, and waits for input of processing data from an adjacent gate device (n101 to n103). When the storage medium receives the transmitted response data, it verifies the passability determination data included in the response data, and opens and closes the gate based on the verification result (n104 to n10).
8). If the passage permission / inhibition determination data is appropriate, the counter for counting the number of permitted passages is incremented. This counter is assigned to a predetermined memory area of the RAM 4. When a passerby passes through the passage within a predetermined time after opening the gate, the counter for counting the number of passes is incremented and the process returns to the standby state (n109, n110).

When processing data is input from an adjacent gate device during standby, whether or not the identification data included in the processing data matches the identification data of the storage medium on which the passability determination processing was performed immediately before is determined. Perform determination (n11
1). If the two coincide, the number of permitted traffics counted by the counter provided in the RAM 4 is compared with the number of permitted traffics (n112), and if they do not match, the number of permitted traffics is decremented (n113, n114).

According to the above-described processing, when a passerby attempts to illegally pass through a plurality of adjacent paths in the gate device having the configuration shown in FIG. 10, the path for which the passability determination processing has been performed first is performed. The matching / mismatch between the number of permitted traffics and the number of traffics is determined in the gate device to be configured. If the number of permitted traffics exceeds the number of traffics for a long time, it is determined that unauthorized use has occurred and the number of permitted traffics is reduced. You. As a result, the number of times of passage is equal to the number of times of passage, and the gate is closed in the passage.

[0056]

According to the present invention, when a plurality of adjacent paths or a two-way path are formed by a plurality of gate devices, other than a path through which a storage medium of a passerby intentionally or erroneously passes. Even when presented to the transmission / reception means of the gate device that constitutes the passage, it is possible to prevent the occurrence of malfunctions in the gate device that constitutes the passage that does not pass by a passerby, and to ensure the unauthorized use of the passerby. It has the advantage of being regulated.
