  As shown in the flowchart of FIG. 14, the inquiry means 104a transmits an inquiry signal to the first parking position sensor 3-1 (steps S141 and S142), and the parking position sensor 3-1 in response thereto. When the read result is returned, the read result, the reception level thereof, and the processed flag = “0” are stored in the first area # 1 of the read result storage unit 107a (step S143). Thereafter, the same processing is performed on the second to nth parking position sensors 3-2 to 3-n (steps S142 to S144), and the processing for the nth parking position sensor 3-n is completed. (Step S145 is YES), the parking position determination means 111 is started (Step S146), and the completion of processing is notified from the parking position determination means 111 (Step S147).

  When the parking position determination unit 111 is activated by the inquiry unit 104a, as shown in the flowchart of FIG. 15, the parking position determination unit 111 pays attention to the first area # 1 of the reading result storage unit 107a, and the processed flag is set to “1”. It is checked whether or not (steps S1051 to S1503).

  If the processed flag is “1” (YES in step S1503), attention is focused on the second area # 2 (S1510, S1502).

  On the other hand, if the processed flag is “0” (NO in step S1503), whether or not a ticket number is stored in the attention area # 1 after the processed flag is changed to “1”. (Steps S1504 and S1505). The item “ticket number” stores a ticket number or information indicating reading failure.

  If the ticket number is not stored (NO in step S1505), information indicating no ticket number is stored in the first area # 1 of the parking position storage unit 112, and then the reading result storage unit 107a. Attention is focused on the second region # 2 (S1509, S1510, S1502).

  On the other hand, when a ticket number is stored in the attention area # 1 (YES in step S1505), first, an area where the same ticket number as the attention area # 1 is stored is read from the read result storage unit 107a. Searching is performed, and the processed flag of each searched area is changed from “0” to “1” (step S1506). Next, from the attention area # 1 and each area searched in step S1506, one area having the highest reception level recorded therein is selected (step S1507). Thereafter, the ticket number in the selected area is stored in an area corresponding to the selected area on the parking position storage unit 112 (step S1508). If, for example, in step S1507, the first area on the reading result storage unit 107a is selected (area corresponding to the first parking position sensor 3-1), the ticket number recorded there is selected. Is stored in the first area (area corresponding to the first parking position sensor 3-1) of the parking position storage unit 112. Thereafter, the parking position determination unit 111 pays attention to the second area # 2 (steps S1510 and S1502), and performs the same processing as described above (steps S1504 to S1508).

  When the above-described processing is performed on all the areas # 1 to #n on the reading result storage unit 107a (YES in step S1511), the parking position determination unit 111 notifies the questioning unit 104a that processing is complete. (Step S1512), the process is terminated.

  On the other hand, when the completion of processing is notified from the parking position determination unit 111 (YES in step S147 in FIG. 14), the inquiry unit 104a performs the processes in steps S141 to S146 described above again. The above processing is always performed in the inquiry unit 104a and the parking position determination unit 111, and the parking position storage unit 112 always stores information indicating the latest parking position.

  Next, an operation when the user returns to the parking lot will be described.

  When the user returns to the parking lot, the user inserts the number ticket 5 into the insertion slot 102 of the parking position display device 1a. When the ticket number 5 is inserted, the ticket number reading means 103a reads the ticket number recorded on the ticket number and passes it to the parking position display means 113.

  When the ticket number is passed from the ticket number reading unit 103a, the parking position display unit 113 searches the parking position storage unit 112 using the ticket number as a key, and uses the sensor number registered in association with the ticket number. Obtained (step S161 in FIG. 16). Thereafter, the parking position display means 113 searches the sensor number display position correspondence table 109 using the sensor number acquired in step S161 as a key, acquires the display position of the parking mark, and as shown in FIG. A parking mark is displayed on the screen (steps S162 and S163).

[Effects of Second Embodiment]
According to the present embodiment, in addition to the effects of the first embodiment, it is possible to shorten the time from when the user inputs a ticket number until the parking position of the user's vehicle is displayed. The effect that can be obtained.

  The reason is that the questioning means 104a periodically associates the reading results of the parking position sensors 3-1 to 3-n with the reception levels and stores them in the reading result storage unit 107a. Each time the reading result and the reception level of each parking position sensor 3-1 to 3-n are stored in the reading result storage unit 107a by the 104a, the vehicle corresponding to each ticket number is based on the contents of the reading result storage unit 107a. This is because the parking position is identified, and the parking position storage unit 112 stores the ticket number and information related to the identified parking position (for example, sensor number) in association with each other and stores them in the parking position storage unit 112.

  The present invention is preferably applied to a large-scale parking lot.
