  Further, the operation mode of the automatic ticket gate 100 may include an operation mode in which both the passage in the direction a and the passage in the direction b shown in FIG. 2 are permitted. In this case, for example, the control unit 150 controls the front display unit 113 and the front display unit 133 to display a mark, a graphic, a character, and the like indicating that the passage is permitted, unless the user is passing. I do. In addition, the ticket gate control unit 150, for example, allows the user to enter from either the a direction or the b direction, and the code display ticket is held over one of the optical reading unit 111 and the optical reading unit 131. Then, the other optical reading unit is invalidated, and a mark, a graphic, or a character indicating that passage is prohibited is displayed on the display unit (the front display unit 113 or the front display unit 133) on the side where the user has not entered. And so on. In addition, the ticket gate control unit 150, for example, allows the user to enter from either side of the a direction or the b direction, and inserts a magnetic ticket into one of the ticket slot 116 and the ticket slot 136. Then, the other ticket entrance is closed, and a mark, a graphic, or a character indicating that passage is prohibited is displayed on the display unit (the front display unit 113 or the front display unit 133) on the side where the user has not entered.

The reflection type photoelectric sensor Sr generates a detection signal indicating whether or not a user's body that reflects light exists in the passage based on the intensity of the received light. The reflection type photoelectric sensor Sr is mainly used for specifying the height of a user existing in a passage. The above-described reflection type photoelectric sensor Sr has been described as being provided in the main unit 110, but is not limited thereto, and may be provided in the slave unit 130, or may be provided in both the main unit 110 and the slave unit 130. Good. The transmission photoelectric sensor St is an example of a “detection unit”.

  FIG. 5 is a diagram illustrating an example of a functional configuration of the automatic ticket gate 100 according to the first embodiment. The automatic ticket gate 100 may further include, in addition to the configuration shown in FIG. 2, a speaker 140 that outputs sound in accordance with an instruction from the ticket gate control unit 150 and a ticket gate storage unit 170 that stores various information. . Further, the ticket gate control unit 150 may include, but is not limited to, the acquisition unit 152, the ticket gate communication unit 154, the decryption determination unit 156, and the passage determination unit 158.

  Some or all of the components of the ticket gate control unit 150 may be realized by a processor such as a CPU (Central Processing Unit) executing a program stored in the ticket gate storage unit 170. Further, some or all of the components of the ticket gate control unit 150 are realized by hardware such as an LSI (Large Scale Integration), an ASIC (Application Specific Integrated Circuit), and an FPGA (Field-Programmable Gate Array). May be provided for realizing the above function.

  The ticket gate storage unit 170 includes, for example, a nonvolatile storage medium such as a ROM (Read Only Memory), a flash memory, a HDD (Hard Disk Drive), and an SD card, a RAM (Random Access Memory), and an MRAM (Magnetoresistive Random Access). And a volatile storage medium such as a register. The ticket gate storage unit 170 stores a program executed by the processor, a fare table 172, station service parameter data 174, and the like.

  FIG. 6 is a diagram illustrating an example of the station service parameter data 174. In the station service parameter data 174, for example, a "parameter value" and a "reference data size" are associated with each "ticket type" indicating the type of the ticket TIX. The types of the ticket TIX are classified into, for example, an entrance ticket, a one-way ticket, a round-trip ticket, an express ticket, and the like. The “parameter value” and the “reference data size” are referenced when identifying whether or not the ticket TIX displaying the display object from which the object data is decoded is a medium that can be processed by the automatic ticket gate 100. Is done. The ticket gate control unit 150 (decryption determination unit 156 described later) may determine these “parameter value” and “reference data size” according to the type of the ticket TIX. Further, the ticket gate control unit 150 (decryption determination unit 156 described later) may update the “parameter value” and the “reference data size” in a predetermined period such as a day or a week. Part (for example, only “parameter value”) or all of the station service parameter data 174 is an example of “comparison target data”.

  The acquisition unit 152 acquires object data from each of the optical reading units 111 and 131. In addition, the acquisition unit 152 acquires the ticket information from each of the magnetic ticket reading units 118 and 138. The acquisition unit 152 supplies the acquired object data and the ticket information to the decryption determination unit 156 and the passage determination unit 158, respectively.

  The ticket gate-side communication unit 154 performs wireless or wired communication with the server device 200, and transmits the object data acquired by the acquisition unit 152 to the server device 200 in accordance with the result of the determination made by the decryption determination unit 156 described later. I do. Further, the ticket gate communication unit 154 receives information from the server device 200.

  The decryption determination unit 156 decrypts (for example, decrypts) data in which the ticket information is encrypted (hereinafter, referred to as encrypted data) included in the object data based on the object data acquired by the acquisition unit 152. Is determined. For example, the decryption availability determination unit 156 determines to decrypt the encrypted data when both of the two determination conditions described later are satisfied, and determines not to decrypt the encrypted data when at least one of the determination conditions is not satisfied. . The encrypted data is an example of “first data”.

  Hereinafter, two determination conditions will be described. The decryption determination unit 156 determines whether the data value of the predetermined data area in the object data matches the “parameter value” in the station service parameter data 174 stored in the ticket gate storage unit 170. I do. For example, when the object data is a one-dimensional data array, the predetermined data area is a set of data from the first data to the subsequent certain data. In addition, the predetermined data area may be, for example, a set of data from the last data to a certain fixed data on the head side when the object data is a one-dimensional data array, or in the middle of the data. Alternatively, a set of data in a certain range may be used. In the present embodiment, as an example, the data from the first data to the data of the fourth byte is treated as a predetermined data area. Note that the size of the predetermined data area is not limited to the above-described numerical value, and may be, for example, 1 byte, 2 bytes, 3 bytes, or 4 bytes or more. Further, the size of the predetermined data area may be in units of bits. The data in the predetermined data area is an example of “second data”.

  The decryption determination unit 156 determines whether or not the data size of the object data matches the data value indicated by the “reference data size” in the station service parameter data 174 stored in the ticket gate storage unit 170. judge. For example, the decryption determination unit 156 expands the object data acquired by the acquisition unit 152 in a RAM or the like in the ticket gate storage unit 170, and acquires the data size of the object data. Then, the decryption determination section 156 determines whether or not the acquired data size matches the reference data size.

  FIG. 7 is a diagram illustrating an example of the structure of the object data. The illustrated example shows a case where the object data is a one-dimensional data array, and the first data is X1 and the last data is Y32. For example, the decryption determination unit 156 searches the station service parameter data 174 and finds data from the first data X1 to 4 bytes, that is, the data value Xa from the data X1 to X4 and the data size Za (= It is determined whether or not a “ticket type” that matches both of them is registered. In the case of the station service parameter data 174 shown in FIG. 6, the one that matches both is registered as an admission ticket, so the decryption availability determination unit 156 determines to decrypt the encrypted data.

  Further, when a label indicating the data size of the object data is attached to the object data, the decryption determination unit 156 refers to the label to make the data size of the object data match the reference data size. It may be determined whether or not.

  FIG. 8 is a diagram illustrating another example of the structure of the object data. The illustrated example shows a case where the object data is a one-dimensional data array, and the first data is X1 and the last data is Y32. Further, a label R indicating the data size is attached to the object data. In this case, the decoding permission / non-permission determining unit 156 acquires the data size of the object data by reading the data value of the label R, and determines whether or not the data size matches the reference data size.

  The decoding possibility determination unit 156 determines that the data value of the predetermined data area in the object data matches the parameter value, and that the data size of the object data matches the reference data size (both the two determination conditions described above are satisfied). ), It is determined to decrypt the encrypted data (Ya in FIGS. 7 and 8). Then, the decryption permission / inhibition determination unit 156 causes the ticket gate machine-side communication unit 154 to transmit the object data including the encrypted data to the server device 200.

  The passability determination unit 158 determines whether the passage of the user is permitted or prohibited based on the ticket information acquired by the acquisition unit 152. The passability determination unit 158 determines whether to permit the user to pass based on the information received by the ticket gate side communication unit 154, that is, the information transmitted by the server device 200 (determination reference data described later). Alternatively, it is determined whether to prohibit. The passability determination unit 158 determines the doors 114, 115, 134, and 135, the speaker 140, the top display units 112 and 132, the front display units 113 and 133, or a combination thereof, according to the determination of permission or prohibition of passage. Control things.

  Hereinafter, the server device 200 will be described. FIG. 9 is a diagram illustrating an example of a functional configuration of the server device 200 according to the first embodiment. The server device 200 includes, for example, a server-side control unit 210 and a server-side storage unit 220. The server-side control unit 210 may include a server-side communication unit 212 and a decryption processing unit 214, but is not limited thereto. Some or all of the components of the server-side control unit 210 may be realized by a processor such as a CPU executing a program stored in the server-side storage unit 220. In addition, some or all of the components of the server-side control unit 210 are realized by hardware such as an LSI, an ASIC, and an FPGA, and may have a circuit configuration for realizing each function.

  The server-side storage unit 220 may be realized by, for example, a nonvolatile storage medium such as a ROM, a flash memory, an HDD, and an SD card, and a volatile storage medium such as a RAM, an MRAM, and a register. The server-side storage unit 220 stores a program to be executed by the processor, and also stores encryption key information 222 and the like.

  FIG. 10 is a diagram illustrating an example of the encryption key information 222. In the encryption key information 222, for example, for each "parameter value", "decryption format" and "encryption key" are associated. The “decryption format” may be, for example, a decryption format corresponding to a common key encryption system such as a block cipher or a stream encryption, or a decryption format corresponding to a public key encryption system such as an RSA encryption or an ElGamal encryption. Is also good. Further, the “decoding format” may be a decoding method using a hash function. The “encryption key” is, for example, station identification information for identifying a station, and may be generated by combining the station identification information of the station where the code display ticket was issued and the date and time when the code display ticket was issued.

  The server-side control unit 210 may determine these “decryption format” and “encryption key” according to the “parameter value” in the station service parameter data 174 or the type of the ticket TIX. For example, as the parameter value is larger, the ticket information may be encrypted (encrypted) using a more complicated encryption method. In this case, the “decryption format” may be changed according to the encryption method. Is set to Also, as the purchase price of the ticket TIX is larger or the validity period of the ticket TIX is longer, the ticket information may be encrypted (encrypted) by a more complicated encryption method. In this case, " The “decryption format” is set to a more complicated decryption format according to the encryption method. The “encryption key” may be set to be longer as the purchase price of the ticket TIX is larger or as the validity period of the ticket TIX is longer. Therefore, the server-side control unit 210 (decoding processing unit 214 described later) determines the “parameter value” that matches the data in the predetermined data area of the object data or the ticket TIX specified from the data in the predetermined data area. “Decryption format” and “encryption key” may be determined according to the type. Further, the server-side control unit 210 (decryption processing unit 214 described later) may update the “decryption format” and the “encryption key” in a predetermined period such as a day or a week.

  The server-side communication unit 212 communicates with the above-described automatic ticket gate 100, and receives the object data transmitted by the automatic ticket gate 100. Further, the server-side communication unit 212 transmits the processing result of the decryption processing unit 214 described later to the automatic ticket gate 100.

  The decryption processing unit 214 refers to the encryption key information 222 stored in the server-side storage unit 220 and decrypts the encryption data included in the object data received by the server-side communication unit 212. For example, the decoding processing unit 214 refers to a predetermined data area of the object data, specifies a “parameter value” that matches the data value of the predetermined data area, and decodes the “parameter value” associated with the “parameter value”. Decrypt the encrypted data of the object data according to the format. At this time, the decryption processing unit 214 decrypts the encrypted data using the encryption key associated with the specified “parameter value”.

  For example, the encrypted data is a decryption method different from the decryption method corresponding to the encryption method used when the ticket information is encrypted, or an encryption key different from the encryption key used when the ticket information is encrypted. If used, the ticket information is converted into a sequence of characters and symbols having a different meaning from the original ticket information, and is not processed by the ticket gate control unit 150. Therefore, when the decryption processing unit 214 converts the encrypted data into information that can be processed by the ticket gate control unit 150 by the decryption processing, the decryption processing unit 214 determines that the encrypted data has been decrypted, and the ticket gate control unit 150 When the information is converted into information that cannot be processed, it is determined that the encrypted data could not be decrypted.

  If the decryption processing unit 214 can decrypt the encrypted data, the server-side communication unit 212 transmits the ticket information (hereinafter, referred to as determination reference data) generated by decrypting the encrypted data to the automatic ticket gate 100 To be sent. Further, when the decryption processing unit 214 cannot decrypt the encrypted data, the decryption processing unit 214 causes the server-side communication unit 212 to transmit error information indicating that the encrypted data could not be decrypted to the automatic ticket gate 100.

  FIG. 11 is a sequence diagram illustrating an example of a processing flow of the transportation system 1 according to the first embodiment. When the code ticket is held over one of the optical reading units 111 and 131, the automatic ticket gate 100 acquires the object data from the optical reading unit and determines whether to decrypt the encrypted data (step S100). ). When decrypting the encrypted data, the automatic ticket gate 100 transmits the object data to the server device 200 (step S102).

  Upon receiving the object data, the server device 200 decrypts the object data (Step S104), and transmits the decrypted determination reference data to the automatic ticket gate 100 (Step S106). Next, upon receiving the criterion data, the automatic ticket gate 100 determines whether or not the user can pass based on the criterion data (step S108).

  Hereinafter, a flow of a series of processes of the ticket gate control unit 150 of the automatic ticket gate 100 will be described. FIG. 12 is a flowchart illustrating an example of a processing flow of the ticket gate control unit 150 according to the first embodiment. The processing of this flowchart is repeatedly performed, for example, at a predetermined cycle.

  First, the decryption determination section 156 determines whether or not the acquisition section 152 has acquired object data from one of the optical reading sections 111 and 131 (step S200). When the object data is acquired by the acquisition unit 152, the decryption determination unit 156 determines whether the data value of the predetermined data area in the object data matches the parameter value in the station service parameter data 174. (Step S202).

  When the data value of the predetermined data area in the object data matches the parameter value, the decryption determination unit 156 determines whether the data size of the object data matches the reference data size in the station service parameter data 174. Is determined (step S204). Note that the decryption determination unit 156 may perform the process of step S204 before performing the process of step S202.

  If the data value of the predetermined data area in the object data does not match the parameter value, or if the data size of the object data does not match the reference data size, the ticket gate control unit 150 ends the processing of this flowchart. .

  On the other hand, when the data value of the predetermined data area in the object data matches the parameter value, and the data size of the object data matches the reference data size, the ticket gate control unit 150 (for example, the decryption determination unit 156) Prohibits the acquisition unit 152 from acquiring the object data from the optical reading units 111 and 131, and inhibits the acquisition unit 152 from acquiring the ticket information from the magnetic ticket reading units 118 and 138 (step S206).

  For example, the ticket gate control unit 150 (for example, the decryption determination unit 156) stops the operation of the acquisition unit 152 so as not to receive the object data and the ticket information transmitted from the optical reading units 111 and 131. The control may be performed, the decryption determination unit 156 may control the object data supplied from the acquisition unit 152 not to be received, or the passability determination unit 158 may control the ticket information supplied from the acquisition unit 152. May be controlled so as not to be received. In addition, the ticket gate control unit 150 (for example, the decryption determination unit 156) operates shutters (not shown) provided at the ticket entrances 116 and 136 to close the ticket entrances 116 and 136, and The magnetic tickets may not be inserted into the insertion ports 116 and 136.

  Next, the decryption permission / non-permission determination unit 156 causes the ticket gate-side communication unit 154 to transmit the object data including the encrypted data to the server device 200 (Step S208).

  Next, the passability determination section 158 determines whether or not error information has been received by the ticket gate side communication section 154 (step S210). When error information is received by the ticket gate-side communication unit 154, the passability determination unit 158 determines that the passage of the user is prohibited, and for example, the top display unit 112 (132) and the front display unit 113 (133). And / or output information indicating that the code display ticket cannot be used to the speaker 140 and control the doors 114 (115) and 134 (135) to be in the closed state to prohibit the passage of the user (step S212). .

  If no error information is received by the ticket gate-side communication unit 154, the passability determination unit 158 determines whether the criterion data is received from the server device 200 by the ticket gate-side communication unit 154 (step S214). When the criterion data is not received by the ticket gate-side communication unit 154, the passability determination unit 158 returns to the process of step S210 described above.

  On the other hand, when the criterion data is received by the ticket gate communication unit 154, the passability determination unit 158 determines whether or not to allow the user to pass based on the criterion data (step S216).

  For example, the passage availability determination unit 158 compares the information such as the validity period, the boarding station (departure station), and the boardable section included in the criterion data (the ticket information) with the fare table 172, so that the own device can use it. Whether the station at which a certain automatic ticket gate 100 is installed matches the boarding station, whether the station at which the automatic ticket gate 100 is installed is within a boardable section, and the boarding section of the user at the participating station It is determined whether some or all of the conditions, such as whether or not the purchase price at the time of the ticket is appropriate and whether or not the time when the code-displayed ticket is held over the optical reading unit 111 (131) is within the validity period, are all determined. If the determination condition is satisfied, the passage of the user is permitted, and if one or more of the determination conditions is not satisfied, the passage of the user is prohibited.

  When permitting the user to pass, for example, the passability determination unit 158 controls the doors 114 (115) and 134 (135) to be in the open state to permit the user to pass (step S218). On the other hand, when prohibiting the passage of the user, the passability determination unit 158 performs the process of step S212 described above.

  Next, the ticket gate control unit 150 permits the acquisition unit 152 to acquire the object data from the optical reading units 111 and 131, and acquires the ticket information from the magnetic ticket reading units 118 and 138 by the acquisition unit 152. Is permitted (step S220). Thus, the processing of this flowchart ends.

  On the other hand, when the object data is not obtained by the obtaining unit 152 in the process of step S200 described above, the decryption determination unit 156 obtains the ticket information from one of the magnetic ticket reading units 118 and 138 by the obtaining unit 152. It is determined whether or not it has been performed (step S222).

  When the ticket information is not acquired by the acquisition unit 152, the ticket gate control unit 150 ends the processing of this flowchart. On the other hand, when the ticket information is acquired by the acquisition unit 152, the ticket gate control unit 150 prohibits the acquisition unit 152 from acquiring object data from the optical reading units 111 and 131, and sets the magnetic ticket by the acquisition unit 152. The acquisition of the ticket information from the reading units 118 and 138 is prohibited (step S224).

  Next, based on the ticket information acquired by the acquisition unit 152, the passage availability determination unit 158 determines whether or not to allow the user to pass (step S226). The passability determination unit 158 performs the process of step S218 described above when permitting the user to pass, and performs the process of step S212 described above when prohibiting the user from passing. Thus, the processing of this flowchart ends.

  In the processing described above, for example, when information is read from a display object different from a display object that can be processed by the automatic ticket gate 100 by the optical reading units 111 and 131, the automatic ticket gate 100 makes a negative determination in step S202 and step S204. (No) determination is performed, so that the subsequent process of determining whether or not the user can pass is not performed. As a result, the automatic ticket gate 100 can reduce the processing load. In addition, when the user holding the medium on which the display object unrelated to the station service is held over enters the passage by mistake because the automatic ticket gate 100 does not perform the pass / fail determination processing based on the object data. However, in this case, the automatic ticket gate 100 performs a no-tag determination process.

  The no-tag determination process is a process of prohibiting the passage of a user when the automatic ticket gate 100 does not permit the passage of the user when the user attempts to pass the passage. For example, the ticket gate control unit 150 determines whether the user has reached a predetermined position in the passage based on the detection signal detected by the transmission type photoelectric sensor St. The predetermined position is, for example, near the middle of the passage viewed from the traveling direction of the user.

  For example, when a user is detected by a transmission type photoelectric sensor St provided around a predetermined position among a plurality of transmission type photoelectric sensors St provided on a housing surface of the main machine 110, the ticket gate control unit 150 Prohibits the acquisition unit 152 from acquiring the object data from the optical reading units 111 and 131, and inhibits the acquisition unit 152 from acquiring the ticket information from the magnetic ticket reading units 118 and 138.

  Then, the ticket gate control unit 150 transmits information indicating that the ticket TIX is not used in the automatic ticket gate 100 to the top display unit 112 (132), the front display unit 113 (133), and / or the speaker 140. Then, the doors 114 (115) and 134 (135) are controlled to be in the closed state to prohibit the passage of the user. When the user exits the passage and the user in the passage is no longer detected by the transmission type photoelectric sensor St, the ticket gate control unit 150 permits the acquisition of object data from the optical reading units 111 and 131. At the same time, acquisition of the ticket information from the magnetic ticket reading units 118 and 138 by the acquisition unit 152 may be permitted.

  Hereinafter, a flow of a series of processes of the server device 200 will be described. FIG. 13 is a flowchart illustrating an example of a processing flow of the server device 200 according to the first embodiment. The processing of this flowchart is repeatedly performed, for example, at a predetermined cycle.

  First, when object data is received by the server-side communication unit 212 (Step S300; Yes), the decryption processing unit 214 refers to the encryption key information 222 stored in the server-side storage unit 220 and refers to the server-side communication unit. The encrypted data included in the object data received by 212 is decrypted (step S302).

  Next, the decryption processing unit 214 determines whether the encrypted data has been successfully decrypted (step S304). When the encrypted data has been successfully decrypted, the decryption processing unit 214 causes the server-side communication unit 212 to transmit the determination reference data obtained by decrypting the encrypted data to the automatic ticket gate 100 (step S306). On the other hand, if the encrypted data could not be decrypted, the decryption processing unit 214 causes the server-side communication unit 212 to transmit error information indicating that the encrypted data could not be decrypted to the automatic ticket gate 100 (step S308). Thus, the processing of this flowchart ends.

  According to the transportation system 1 in the first embodiment described above, the encrypted data included in the object data is decrypted based on the object data in which the information of the display object displayed on the medium such as the code display ticket is decoded. By determining whether or not the ticket TIX on which the display object not related to the station service is displayed on the automatic ticket gate 100 is determined based on the object data of the display object not related to the station service. The determination as to whether or not the vehicle can pass is not performed. As a result, the transportation system 1 according to the first embodiment can suppress an increase in the processing load.

  Further, according to the transportation system 1 in the first embodiment, since the decryption format of the encrypted data and the encryption key used for decryption are changed by referring to the predetermined data area of the object data, the confidentiality of the ticket information is changed. Can be improved.

  Further, according to the transportation system 1 in the first embodiment, when the ticket TIX displaying the display object unrelated to the station service is held over the automatic ticket gate 100, the information acquisition by the various reading units is performed. Does not perform control processing. Generally, when a ticket TIX such as a code-display ticket or a magnetic ticket is used for the automatic ticket gate 100, the automatic ticket gate 100 waits for another ticket until it completes the pass / fail determination for the ticket TIX. Restrict use of TIX. In the present embodiment, the automatic ticket gate 100 performs a process of controlling acquisition of information by various reading units before determining whether or not passage is possible. At this time, for example, the ticket gate control unit 150 activates shutters (not shown) provided at the ticket entrances 116 and 136 to prohibit the acquisition of the ticket information by the magnetic ticket reading units 118 and 138. When performing the process of closing the ticket entrances 116 and 136 with the opening and closing of the shutter, processing time is required for opening and closing the shutter.

  On the other hand, in the first embodiment, when the code display ticket is held over the automatic ticket gate 100, the predetermined data area of the object data is changed before performing the process of controlling the acquisition of information by the various reading units. Since it is determined with reference to whether the code display ticket is valid, it is possible to suppress an increase in processing time. As a result, the traffic system 1 may be able to reduce the processing time from about several tens of ms to about several ms, for example.

(Modification of First Embodiment)
The passability determination unit 158 of the ticket gate control unit 150 described above may be included inside the server control unit 210. In this case, the passability determination unit 158 of the ticket gate control unit 150 may be omitted. For example, the passability determination unit of the server-side control unit 210 determines whether to permit the user to pass based on the determination reference data generated by the decryption processing unit 214. Then, the passability determination unit of the server-side control unit 210 causes the server-side communication unit 212 to transmit information indicating a determination result of permitting or prohibiting the user's passage to the automatic ticket gate 100. Upon receiving this information, the automatic ticket gate 100 receives the doors 114, 115, 134, and 135, the speaker 140, and the upper surface in accordance with the determination result (permission or prohibition of passage) by the passability determination unit of the server-side controller 210. The display units 112 and 132, the front display units 113 and 133, or a combination thereof are controlled. Thereby, according to the modification of the first embodiment, similarly to the first embodiment, an increase in the processing load can be suppressed.

(Second embodiment)
Hereinafter, the traffic system 1 in the second embodiment will be described. The transportation system 1 according to the second embodiment differs from the transportation system 1 according to the first embodiment in that the automatic ticket gate 100A decrypts encrypted data included in object data. Therefore, the following description focuses on the differences, and a description of common parts is omitted.

  FIG. 14 is a diagram illustrating an example of a functional configuration of the automatic ticket gate 100A according to the second embodiment. The ticket gate control unit 150A of the automatic ticket gate 100A in the second embodiment includes a decryption processing unit 160 in addition to the components of the ticket gate control unit 150 in the first embodiment described above. Note that the ticket gate side communication unit 154 may be omitted.

  In addition, the ticket gate storage unit 170A of the automatic ticket gate 100A stores encryption key information 176 in addition to the information stored in the ticket gate storage unit 170 in the first embodiment described above. The encryption key information 176 stored in the ticket gate storage unit 170A may be the same as or equivalent to the encryption key information 222 stored in the server storage unit 220.

  The decryption processing unit 160 refers to the encryption key information 176 stored in the ticket gate storage unit 170A, and decrypts the encrypted data included in the object data acquired by the acquisition unit 152.

  Hereinafter, a flow of a series of processes of the ticket gate control unit 150A of the automatic ticket gate 100A will be described. FIG. 15 is a flowchart illustrating an example of a process flow of the ticket gate control unit 150A according to the second embodiment. The processing of this flowchart is repeatedly performed, for example, at a predetermined cycle.

  First, the decryption determination unit 156 determines whether the acquisition unit 152 has acquired object data from one of the optical reading units 111 and 131 (step S400). When the object data is acquired by the acquisition unit 152, the decryption determination unit 156 determines whether the data value of the predetermined data area in the object data matches the parameter value in the station service parameter data 174. (Step S402).

  When the data value of the predetermined data area in the object data matches the parameter value, the decryption determination unit 156 determines whether the data size of the object data matches the reference data size in the station service parameter data 174. Is determined (step S404). Note that the decryption determination unit 156 may perform the processing of step S402 after performing the processing of step S404.

  If the data value of the predetermined data area in the object data does not match the parameter value, or if the data size of the object data does not match the reference data size, the ticket gate control unit 150A ends the processing of this flowchart. .

  On the other hand, when the data value of the predetermined data area in the object data matches the parameter value, and the data size of the object data matches the reference data size, the ticket gate control unit 150A (for example, the decryption determination unit 156) Prohibits the acquisition unit 152 from acquiring the object data from the optical reading units 111 and 131, and inhibits the acquisition unit 152 from acquiring the ticket information from the magnetic ticket reading units 118 and 138 (step S406).

  Next, the decryption processing unit 160 refers to the encryption key information 176 stored in the ticket gate storage unit 170A to decrypt the encrypted data included in the object data acquired by the acquisition unit 152 (Step S408). Next, the decryption processing unit 160 determines whether or not the encrypted data has been successfully decrypted (Step S410).

  If the encrypted data is not decrypted by the decryption processing unit 160, the passability determination unit 158 determines that the passage of the user is prohibited, and for example, the top display unit 112 (132), the front display unit 113 (133) and And / or output information indicating that the code display ticket cannot be used to the speaker 140 and control the doors 114 (115) and 134 (135) to be in the closed state to prohibit the passage of the user (step S412).

  On the other hand, when the encrypted data is decrypted by the decryption processing unit 160, the passability determination unit 158 determines whether to permit the user to pass based on the determination reference data decrypted by the decryption processing unit 160. (Step S414).

  When permitting the passage of the user, for example, the passability determination unit 158 controls the doors 114 (115) and 134 (135) to be in the open state to permit the passage of the user (step S416). On the other hand, when the passage of the user is prohibited, the passage possibility determination unit 158 performs the processing of step S412 described above.

  Next, the ticket gate control unit 150 permits the acquisition unit 152 to acquire the object data from the optical reading units 111 and 131, and acquires the ticket information from the magnetic ticket reading units 118 and 138 by the acquisition unit 152. Is permitted (step S418). Thus, the processing of this flowchart ends.

  On the other hand, when the object data is not acquired by the acquiring unit 152 in the process of step S400 described above, the decryption determination unit 156 acquires the ticket information from one of the magnetic ticket reading units 118 and 138 by the acquiring unit 152. It is determined whether or not it has been performed (step S420).

  When the ticket information is not acquired by the acquisition unit 152, the ticket gate control unit 150 ends the processing of this flowchart. On the other hand, when the ticket information is acquired by the acquisition unit 152, the ticket gate control unit 150 prohibits the acquisition unit 152 from acquiring object data from the optical reading units 111 and 131, and sets the magnetic ticket by the acquisition unit 152. The acquisition of the ticket information from the reading units 118 and 138 is prohibited (step S422).

  Next, the passability determination unit 158 determines whether to permit the user to pass based on the ticket information acquired by the acquisition unit 152 (step S424). The passability determination unit 158 performs the process of step S416 described above when permitting the user to pass, and performs the process of step S412 described above when prohibiting the user from passing. Thus, the processing of this flowchart ends.

  According to the transportation system 1 in the second embodiment described above, similarly to the first embodiment described above, the ticket TIX on which the display object irrelevant to the station service is displayed is overlaid on the automatic ticket gate 100. In such a case, it is possible to prevent the determination as to whether or not passage is possible based on the object data of the display object irrelevant to the station service. As a result, the traffic system 1 according to the second embodiment can suppress an increase in the processing load.

(Third embodiment)
Hereinafter, the traffic system 1 in the second embodiment will be described. The traffic system 1 according to the second embodiment differs from the traffic systems 1 according to the first and second embodiments in that the ticket gate control unit 150B of the automatic ticket gate 100B acquires the determination reference data from the optical reading unit. I do. Therefore, the following description focuses on the differences, and a description of common parts is omitted.

  FIG. 16 is a diagram illustrating an example of a functional configuration of the automatic ticket gate 100B according to the third embodiment. The optical reading units 111B and 131B of the automatic ticket gate 100B according to the third embodiment include a decoding processing unit therein, decode information indicating a display object read from a code display ticket, and are included in the decoded object data. The encrypted data is further decrypted to generate determination reference data.

  The acquisition unit 152 of the ticket gate control unit 150B acquires the determination reference data from each of the optical reading units 111B and 131B. The acquisition unit 152 supplies the acquired determination criterion data to the passability determination unit 158. The passability determination unit 158 determines whether to permit or prohibit the passage of the user based on the determination reference data acquired by the acquisition unit 152.

  According to the transportation system 1 in the third embodiment described above, similarly to the first and second embodiments described above, the ticket TIX in which the display object irrelevant to the station service is displayed on the automatic ticket gate 100. When is shaded, it is possible not to make a determination as to whether or not it is possible to pass based on the object data of the display object irrelevant to the station service. As a result, the transportation system 1 according to the third embodiment can suppress an increase in the processing load.

  According to at least one embodiment described above, it is determined whether or not to decrypt encrypted data included in object data based on decoded object data of a display object displayed on a medium such as a code display ticket. Accordingly, when the ticket TIX on which the display object not related to the station service is displayed on the automatic ticket gate 100 is shaded, it is determined whether or not passage is possible based on the object data of the display object not related to the station service. Can not be. As a result, the traffic system 1 in the embodiment can suppress an increase in the processing load.
