The stored processed flag is rewritten to “ON”. Further, the processing deeming unit 38 rewrites the processed flag stored in the matching queue in association with the reception information not selected by the selection unit 35 to “ON”. Note that the process deeming unit 38 does not record each received information in the business process queue 37.

The receipt server 3 performs the following operation | movement by providing the said structure.
The range determination unit 33 is a period from the latest reception time associated with the processed reception information to a time that is the reception adjustment time before the reception time associated with the reception information last received by the antenna 1. A certain processing target range is determined. The processed determination unit 34 extracts reception information associated with a reception time indicating a time within the processing target range and received from a vehicle other than the vehicle that transmitted the processed reception information. The selection unit 35 receives reception information received from different vehicles one by one from the reception information extracted by the processed determination unit 34 and the reception information associated with the reception time indicating the time after the processing target range. select. The business processing unit 36 uses the reception information selected by the selection unit 35 among the reception information stored in the matching queue 32 for processing, and sets the reception information as processed. The processing deeming unit 38 processes the reception information that is not extracted by the processed determination unit 34 and the reception information that is not selected by the selection unit 35 among the reception information associated with the reception time indicating the time within the processing target range. It is assumed that it has been processed without being used.
By performing the above operation, the receiving server 3 can prevent the same vehicle from being processed repeatedly using the received information received from the same vehicle.

Next, the operation of the receipt server 3 according to this embodiment will be described.
FIG. 4 is a flowchart showing the operation of the receipt server 3.
When the antenna 1 captures a signal from the vehicle and the lane server 2 receives the reception information via the antenna 1, the lane server 2 outputs a communication record with the vehicle to the receiving server 3.
When receiving server 3 receives a communication record from lane server 2, recording unit 31 records information indicating the communication record in a storage area corresponding to input lane server 2 in matching queue 32 (step S1). .

When information is newly recorded in the matching queue 32, the range determination unit 33 reads from the matching queue 32 the one that indicates the latest time among the reception times associated with the processed flag that indicates “ON” ( Step S2). When the example illustrated in FIG. 3 is used, the range determination unit 33 reads “2010/09/30 10:08”. Moreover, the range determination part 33 reads the reception time which shows the latest time from the memory area corresponding to each lane server 2 in the matching queue 32 (step S3). Next, the range determination part 33 specifies the reception time which shows the earliest time among the reception times read by step S3 (step S4). When the example illustrated in FIG. 3 is used, the range determination unit 33 reads “2010/09/30 10:13”.
The range determination unit 33 sets the processing target range to a range in which the reception time read in step S2 is the start time, and the reception adjustment time (for example, 5 minutes) before the reception time specified in step S4 is the end time. Determine (step S5).

When the range determination unit 33 determines the processing target range, the processed determination unit 34 indicates the reception time within the processing target range from the matching queue 32 among the reception information associated with the processed flag indicating “OFF”. The reception information associated with the reception time indicating the earliest time is read (step S6).
Next, the processed determination unit 34 reads the reception information stored in the matching queue 32 in association with the reception time corresponding to the read information in the past search adjustment period (step S7). The past search adjustment period is a period from the reception time associated with the read reception information to the time 10 minutes before the reception time, as described above.

  Next, the processed determination unit 34 determines whether the reception information read in step S7 includes reception information associated with the same vehicle identification information as the vehicle identification information associated with the reception information read in step S6. Is determined (step S8). As a result, the processed determination unit 34 reads out the reception information included in the processing target range from the matching queue 32, and searches whether there is reception information associated with the same vehicle identification information as the reception information in the past.

  When the processed determination unit 34 determines that the reception information read in step S7 includes reception information associated with the same vehicle identification information as the vehicle identification information associated with the reception information read in step S6 ( (Step S8: YES), the process deeming unit 38 rewrites the processed flag stored in the matching queue 32 to “ON” in association with the reception information read by the processed determination unit 34 in Step S6 (Step S9).

  On the other hand, the processed determination unit 34 determines that the reception information read in step S7 does not include the reception information associated with the same vehicle identification information as the vehicle identification information associated with the reception information read in step S6. In the case (step S8: NO), the selection unit 35 receives the reception information stored in the matching queue 32 in association with the reception time corresponding to the future search adjustment period of the reception information read by the processed determination unit 34 in step S6. Is read (step S10). As described above, the future search adjustment period is a period from the reception time associated with the read reception information to the time 10 minutes after the reception time.

  Next, the selection unit 35 receives the reception information associated with the same vehicle identification information as the vehicle identification information associated with the reception information read out by the processed determination unit 34 at step S6 out of the reception information read out at step S10. Specify (step S11). Next, the selection unit 35 selects information with the highest priority from the reception information specified in step S11 (step S12). Here, high priority information is information that is not damaged, and is information that can read valid detailed information when the received information is billing detailed information, for example.

Then, the business processing unit 36 records the reception information selected by the selection unit 35 in step S12 in the business processing queue 37, and rewrites the processed flag stored in the matching queue 32 in association with the received information to “ON”. (Step S13).
Further, the processing deeming unit 38 sets the processed flag stored in the matching queue 32 to “ON” in association with the reception information not selected in step S12 among the reception information read by the selection unit 35 in step S11. Rewrite (step S14).

  When the processing deeming unit 38 rewrites the processed flag of the matching queue 32 to “ON” in step S9 or step S14, the processed determination unit 34 is associated with the processed flag indicating “OFF” in the matching queue 32, and It is determined whether there is reception information associated with the reception time within the processing target range (step S15). When it is determined that there is corresponding reception information (step S15: YES), the processed determination unit 34 repeats the operations after step S6. On the other hand, when it is determined that there is no corresponding reception information (step S15: NO), the processed determination unit 34 ends the operation and waits for input of a new communication record from the lane server 2.

FIG. 5 is a diagram illustrating an example of communication records output from the lane server 2.
Hereinafter, the operation of the receipt server 3 will be described by taking as an example the case where the lane server 2 receives the reception information in the order shown in FIG.
When the lane server 2A receives the reception information from the vehicle A at 10:00, the range determination unit 33 of the collection server 3 determines the processing target range by executing steps S2 to S5. At this time, since reception information is not recorded in the storage area corresponding to the lane server 2B, the processing target range determined in step S5 becomes an invalid value. Therefore, at this time, the process for determining whether or not the information stored in the matching queue 32 is used for the business process is not executed.

  At 10:02, when the lane server 2B receives the reception information from the vehicle B, the range determination unit 33 of the collection server 3 determines the processing target range by executing steps S2 to S5. At this time, the reception time specified in step S4 is 10:00. Then, the range determining unit 33 determines the period up to 9:55 before 5 minutes (reception adjustment time) at 10:00 as the processing target range. Since the reception information associated with the reception time before 9:55 is not stored in the matching queue 32, it is determined at this point whether or not the information stored in the matching queue 32 is used for business processing. Processing is not performed. Hereinafter, when the lane server 2A receives the reception information from the vehicle B at 10:03, the lane server 2A receives the reception information from the vehicle A at 10:04, and the lane server 2A from the vehicle C at 10:07. Similarly, when the reception information is received, the processing after step S6 is not executed.

  When the vehicle server B receives the reception information from the vehicle D at 10:08, the range determination unit 33 of the collection server 3 determines the processing target range by executing steps S2 to S5. At this time, the reception time specified in step S4 is 10:07. Then, the range determining unit 33 determines the period up to 10:02 five minutes before 10:07 as the processing target range.

Next, in step S <b> 6, the processed determination unit 34 reads reception information associated with the earliest reception time within the processing target range and associated with the processed flag “OFF”. That is, the processed determination unit 34 reads the reception information received from the vehicle A at 10:00 by the lane server 2A from the matching queue 32.
Next, the processed determination unit 34 reads the reception information associated with the reception time indicating between 9:50 and 10:00 (past search adjustment period). At this time, the matching queue 32 does not store reception information associated with a reception time indicating a time between 9:50 and 10:00. Therefore, the processed determination unit 34 determines that there is no reception information associated with the vehicle identification information indicating the vehicle A in the reception information read out in step S8.

  Next, the selection part 35 reads the reception information linked | related with the reception time which shows between 10: 00-10: 10 (future search adjustment period) by step S10. That is, the reception information received from the vehicle B at 10:02, the reception information received from the vehicle B at 10:03, the reception information received from the vehicle A at 10:04, the reception information received from the vehicle C at 10:07, And the reception information received from the vehicle D is read at 10:08. Next, the selection part 35 specifies the reception information linked | related with the vehicle identification information which shows the vehicle A from read reception information by step S11. That is, the reception information received from the vehicle A at 10:04 is specified.

Next, in step S12, the selection unit 35 selects a higher priority among the reception information received from the vehicle A at 10:00 and the reception information received from the vehicle A at 10:04. At this time, when the selection unit 35 selects the reception information received from the vehicle A at 10:04, the business processing unit 36 stores the reception information received from the vehicle A at 10:04 in the business processing queue 37 in step S13. Record. At this time, the business processing unit 36 records the reception time of the reception information received from the vehicle A at 10:04 in the business processing queue 37 as 10:00. As a result, the reception information is stored in the job processing queue 37 in the order of reception time.
Then, the task processing unit 36 rewrites the processed flag stored in the matching queue 32 to “ON” in association with the reception information received from the vehicle A at 10:04. Further, the processing deeming unit 38 rewrites the processed flag stored in the matching queue 32 to “ON” in association with the reception information received from the vehicle A at 10:00 in step S14.
Thus, according to this embodiment, when the vehicle stays in the communication range of the antenna 1 due to traffic jams or the like, when the antenna 1 communicates with the same vehicle a plurality of times, the same vehicle is duplicated. Processing can be prevented.

  Next, in step S15, the processed determination unit 34 determines whether there is reception information that is associated with a reception time that indicates a period up to 10:02 and that the processed flag indicates “OFF”. . At this time, since the processed flag associated with the received information received from the vehicle B at 10:02 indicates “OFF”, the processed determination unit 34 associates with the reception time indicating the period until 10:02. It is determined that there is received information whose processed flag indicates “OFF”.

Next, in step S <b> 6, the processed determination unit 34 reads reception information associated with the earliest reception time within the processing target range and associated with the processed flag “OFF”. That is, the processed determination unit 34 reads the reception information received from the vehicle B by the lane server 2B at 10:02 from the matching queue 32.
Next, the processed determination unit 34 reads the reception information associated with the reception time indicating between 9:52 and 10:02. That is, the processed determination unit 34 reads the reception information received from the vehicle A at 10:00. Next, the processed determination unit 34 determines whether the read reception information is received from the vehicle B.

  Since the reception information read in step S7 is not received from the vehicle B, the selection unit 35 reads the reception information associated with the reception time indicating between 10:02 and 10:12 in step S10. That is, the reception information received from the vehicle B at 10:03, the reception information received from the vehicle A at 10:04, the reception information received from the vehicle C at 10:07, and the reception information received from the vehicle D at 10:08 Is read. Next, the selection part 35 specifies the reception information linked | related with the vehicle identification information which shows the vehicle B from read reception information by step S11. That is, the reception information received from the vehicle B at 10:03 is specified.

Next, in step S12, the selection unit 35 selects the higher priority among the reception information received from the vehicle B at 10:02 and the reception information received from the vehicle B at 10:03. At this time, if the selection unit 35 selects the reception information received from the vehicle B at 10:02, the business processing unit 36 stores the reception information received from the vehicle B at 10:02 in the business processing queue 37 in step S13. Record.
Then, the business processing unit 36 rewrites the processed flag stored in the matching queue 32 to “ON” in association with the reception information received from the vehicle B at 10:02. Further, the processing deeming unit 38 rewrites the processed flag stored in the matching queue 32 to “ON” in association with the reception information received from the vehicle B at 10:03 in step S14.
Thus, according to the present embodiment, when the plurality of antennas 1 communicate with the same vehicle, it is possible to prevent the same vehicle from being processed repeatedly.

  Next, in step S15, the processed determination unit 34 determines whether there is reception information that is associated with a reception time that indicates a period up to 10:02 and that the processed flag indicates “OFF”. . At this time, since all the processed flags associated with the reception times indicating the period until 10:02 indicate “ON”, the processed determination unit 34 ends the processing and receives information from the lane server 2. Wait for input.

  When the vehicle server A receives the reception information from the vehicle C at 10:15, the range determination unit 33 of the collection server 3 determines the processing target range by executing steps S2 to S5. At this time, the reception time read in step S2 is 10:04. On the other hand, the reception time specified in step S4 is 10:08. Therefore, the processing target range determined in step S5 becomes an invalid value, and the process for determining whether or not the information stored in the matching queue 32 is used for the business process is not executed.

  When the vehicle server B receives the reception information from the vehicle A at 10:21, the range determination unit 33 of the collection server 3 determines the processing target range by executing steps S2 to S5. At this time, the reception time read in step S2 is 10:04. On the other hand, the reception time specified in step S4 is 10:15. Therefore, the range determination unit 33 determines the period from 10:04 to 10:10, 5 minutes before 10:15, as the processing target range.

Next, in step S <b> 6, the processed determination unit 34 reads reception information associated with the earliest reception time within the processing target range and associated with the processed flag “OFF”. That is, the processed determination unit 34 reads the reception information received from the vehicle C at 10:07 by the lane server 2A from the matching queue 32.
Next, the processed determination unit 34 reads the reception information associated with the reception time indicating between 9:57 and 10:07. That is, the processed determination unit 34 receives the reception information received from the vehicle A at 10:00, the reception information received from the vehicle B at 10:02, the reception information received from the vehicle B at 10:03, and the vehicle at 10:04. Read the received information received from A. Next, the processed determination unit 34 determines whether the read reception information is received from the vehicle C.

  Since none of the reception information read in step S7 has been received from the vehicle C, the selection unit 35 reads the reception information associated with the reception time indicating between 10:07 and 10:17 in step S10. That is, the reception information received from the vehicle D at 10:08 and the reception information received from the vehicle C at 10:15 are read out. Next, the selection part 35 specifies the reception information linked | related with the vehicle identification information which shows the vehicle C from read reception information by step S11.

  Among the reception information read in step S11, there is no reception information associated with the vehicle identification information indicating the vehicle C. Therefore, the selection unit 35 selects the reception information received from the vehicle C at 10:07 in step S12. Next, the business processing unit 36 records the received information received from the vehicle C at 10:07 in the business processing queue 37 and sets the processed flag stored in the matching queue 32 in association with the received information to “ON”.

  Next, in step S15, the processed determination unit 34 determines whether there is reception information that is associated with a reception time that indicates a period up to 10:02 and that the processed flag indicates “OFF”. . At this time, since the processed flag associated with the received information received from the vehicle D at 10:08 indicates “OFF”, the processing received from the vehicle D at 10:08 is performed by executing the processing after step S6. The information is recorded in the business process queue 37, and the processed flag stored in the matching queue 32 in association with the received information is rewritten to “ON”.

  At 10:27, when the vehicle server A receives the reception information from the vehicle E, the range determination unit 33 of the collection server 3 determines the processing target range by executing steps S2 to S5. At this time, the reception time read in step S2 is 10:08. On the other hand, the reception time specified in step S4 is 10:21. Therefore, the range determination unit 33 determines the period from 10:08 to 10:16, 5 minutes before 10:21, as the processing target range.

Next, in step S <b> 6, the processed determination unit 34 reads reception information associated with the earliest reception time within the processing target range and associated with the processed flag “OFF”. That is, the processed determination unit 34 reads the reception information received from the vehicle C by the lane server 2A at 10:15 from the matching queue 32.
Next, the processed determination unit 34 reads the reception information associated with the reception time indicating between 10:05 and 10:15. That is, the processed determination unit 34 reads out the reception information received from the vehicle C at 10:07 and the reception information received from the vehicle D at 10:08. Next, the processed determination unit 34 determines whether the read reception information is received from the vehicle C.

Since the received information received from the vehicle C at 10:07 is received from the vehicle C, the processing deeming unit 38 is stored in the matching queue 32 in association with the received information received from the vehicle C at 10:15. The processed flag is rewritten to “ON”.
Thus, according to the present embodiment, when the vehicle stays in the communication range of the antenna 1 due to traffic jams or the like and the antenna 1 communicates with the same vehicle a plurality of times, the previous reception information has already been processed. Even when the vehicle is running, it is possible to prevent the same vehicle from being processed repeatedly.

  When the vehicle server B receives the reception information from the vehicle F at 10:30, the range determination unit 33 of the toll server 3 determines the processing target range by executing steps S2 to S5. At this time, the reception time read in step S2 is 10:15. On the other hand, the reception time specified in step S4 is 10:27. Therefore, the range determination unit 33 determines the period from 10:15 to 10:22 five minutes before 10:27 as the processing target range.

Next, in step S <b> 6, the processed determination unit 34 reads reception information associated with the earliest reception time within the processing target range and associated with the processed flag “OFF”. That is, the processed determination unit 34 reads out the reception information received from the vehicle A at 10:21 by the lane server 2B from the matching queue 32.
Next, the processed determination unit 34 reads reception information associated with a reception time indicating between 10:11 and 10:21. That is, the processed determination unit 34 reads the reception information received from the vehicle C at 10:15. Next, the processed determination unit 34 determines whether the read reception information is received from the vehicle A.

  Since the reception information read in step S7 is not received from the vehicle A, the selection unit 35 reads the reception information associated with the reception time indicating between 10:21 and 10:31 in step S10. That is, the reception information received from the vehicle E at 10:27 and the reception information received from the vehicle F at 10:30 are read out. Next, the selection part 35 specifies the reception information linked | related with the vehicle identification information which shows the vehicle A from read reception information by step S11.

There is no reception information associated with the vehicle identification information indicating the vehicle A in the reception information read in step S11. Accordingly, the selection unit 35 selects the reception information received from the vehicle A at 10:21 in step S12. Next, the business processing unit 36 records the received information received from the vehicle A at 10:21 in the business processing queue 37 and sets the processed flag stored in the matching queue 32 in association with the received information to “ON”. Rewrite to That is, even if reception information (first reception information) from the vehicle A has already been received at 10:00 or 10:04, it is again after a predetermined time (in this embodiment, 10 minutes) or more after the previous reception time. When receiving information (second received information) is received from the same vehicle, the selection unit 35 selects the received information, and the business processing unit 36 records the received information in the business processing queue 37.
Thus, according to this embodiment, when the same vehicle goes around the road and returns again, or when the same vehicle once exits, enters again from the entrance, and passes through the same exit again. In addition, the processing can be performed every time the road passes, instead of performing the processing only once.

Next, in the case where the lane server 2 receives the reception information in the order shown in FIG. 5, from 10:00 to 10:31, the communication between the lane server 2A and the receiving server 3 is interrupted. The operation of the receipt server 3 will be described.
When communication between the lane server 2A and the receiving server 3 is interrupted from 10:00 to 10:31, only the reception information received by the lane server 2B is stored in the matching queue 32 during that time. . Accordingly, since the reception information is not recorded in the storage area corresponding to the lane server 2A from 10:00 to 10:31, the processing target range determined in step S5 becomes an invalid value. Therefore, during this time, the process for determining whether or not the information stored in the matching queue 32 is used for the business process is not executed.
Accordingly, it is possible to prevent the processing from being performed using the reception information with low priority received by the lane server 2B while communication with the lane server 2A is interrupted.

  At 10:31, when the information received by the lane server 2A from 10:00 to 10:31 is input to the receiving server 3 from the lane server 2A, the range determining unit 33 of the receiving server 3 performs steps S2 to S5. To determine the processing target range. At this time, the reception time specified in step S4 is 10:27. And the range determination part 33 determines the period to 10:22 5 minutes before 10:27 as a process target range.

Next, in step S <b> 6, the processed determination unit 34 reads reception information associated with the earliest reception time within the processing target range and associated with the processed flag “OFF”. That is, the processed determination unit 34 reads the reception information received from the vehicle A at 10:00 by the lane server 2A from the matching queue 32.
Next, the processed determination unit 34 reads the reception information associated with the reception time indicating between 9:50 and 10:00. At this time, the matching queue 32 does not store reception information associated with a reception time indicating a time between 9:50 and 10:00. Therefore, the processed determination unit 34 determines that there is no reception information associated with the vehicle identification information indicating the vehicle A in the reception information read out in step S8.

  Next, the selection part 35 reads the reception information linked | related with the reception time which shows between 10: 00-10: 10 by step S10. That is, the reception information received from the vehicle B at 10:02, the reception information received from the vehicle B at 10:03, the reception information received from the vehicle A at 10:04, the reception information received from the vehicle C at 10:07, And the reception information received from the vehicle D is read at 10:08. Next, the selection part 35 specifies the reception information linked | related with the vehicle identification information which shows the vehicle A from read reception information by step S11. That is, the reception information received from the vehicle A at 10:04 is specified.

Next, in step S12, the selection unit 35 selects a higher priority among the reception information received from the vehicle A at 10:00 and the reception information received from the vehicle A at 10:04. At this time, when the selection unit 35 selects the reception information received from the vehicle A at 10:04, the business processing unit 36 stores the reception information received from the vehicle A at 10:04 in the business processing queue 37 in step S13. Record.
Then, the task processing unit 36 rewrites the processed flag stored in the matching queue 32 to “ON” in association with the reception information received from the vehicle A at 10:04. Further, the processing deeming unit 38 rewrites the processed flag stored in the matching queue 32 to “ON” in association with the reception information received from the vehicle A at 10:00 in step S14.

  Thus, according to the present embodiment, even if communication with the lane server 2 is interrupted, it is possible to prevent the process from being erroneously executed. In other words, when communication with the same vehicle is performed a plurality of times in a short period (10:00 and 10:04) due to traffic jams or the like, the process is erroneously executed for the same vehicle. Can be prevented. Furthermore, when communication with the same vehicle is performed a plurality of times at intervals of time (10:00 and 10:21) by passing through the same exit a plurality of times, the process may be executed every time the vehicle passes. it can.
