<Processing Flow of Parking Management System>
FIG. 5 is a first diagram showing the processing flow of the parking management system.
Next, processing of the parking management system 100 will be described.
First, a user who parks a vehicle 2 in a parking space purchases a parking ticket 3 using a ticket issuing machine 1. - 特許庁At this time, the ticket issuing machine 1 accepts the insertion of money from the user (step S101). The ticket issuing processing unit 132 of the ticket issuing machine 1 calculates the total amount of money and determines whether the total amount is equal to or greater than a predetermined parking fee. When the total amount is equal to or greater than the predetermined parking fee, the ticket issuing processing unit 132 outputs to the writing processing unit 131 a request to write information to the RFID tag 4 of the parking ticket 3 stored inside the ticket issuing machine 1 . The write processing unit 131 writes information to the RFID tag 4 of the parking ticket 3 to be issued (step S102). At this time, the ticket issuing processing unit 132 controls the ticket issuing mechanism 12 to perform control such as transporting the parking ticket 3 to a predetermined position for writing information on the parking ticket 3 to be issued.

Examples of information to be written in the RFID tag 4 include a ticket issuing number, ticket issuing time, and ticket issuing machine ID. The write processing unit 131 may further write the parking space number input by the user to the RFID tag 4 . The write processing unit 131 acquires the face of the user's license read by an optical reading device separately provided in the ticket issuing machine 1, and detects information such as the name, address, and license number from the image of the face of the license. Then, such information may be further written to the RFID tag 4. FIG. The write processing unit 131 may also write other information to the RFID tag 4 . Other information may be, for example, contact information such as the user's e-mail address and telephone number input to the ticket issuing machine 1 by the user. Then, the ticket issuing processing unit 132 performs control to transmit the parking ticket 3 to which the RFID tag 4 in which the information is written by the writing processing unit 131 is attached from the ticket issuing port (step S103).

A user obtains a parking ticket 3 from the ticket issuing port. The user places parking ticket 3 on the dashboard. Alternatively, the user may attach the parking ticket 3 to the windshield or dashboard by peeling off the sticker covering the adhesive portion of the parking ticket 3 and pressing the adhesive portion onto the windshield or dashboard.

When the issuance of the parking ticket 3 is completed, the ticket issuing processing unit 132 outputs to the vehicle condition management unit 134 the information indicating the completion of issuing the parking ticket, the issue number specifying the issued parking ticket 3, and the issuing time. The vehicle status management unit 134 records the parking management information including the ticket issuing number, the ticket issuing time, and the ticket issuing machine ID in the storage unit such as the HDD 17 (step S104). The parking management information may further include other information written in the RFID tag 4 of the issued parking ticket 3 . Vehicle status management unit 134 outputs the parking management information to output unit 135 . The output unit 135 transmits the parking management information to the parking management server 5 (step S105). The parking management unit 512 of the parking management server 5 records the parking management information in the storage unit such as the HDD 54 (step S106).

The vehicle status management unit 134 outputs an information acquisition request to the information acquisition unit 133 when the parking management information is recorded in the storage unit. The information acquisition unit 133 controls the wireless communication device 11 to transmit a read signal based on the information acquisition request. The information acquisition unit 133 controls the wireless communication device 11 to transmit the reading signal at predetermined time intervals such as one minute intervals. The wireless communication device 11 transmits a reading signal based on the control from the information acquisition section 133 (step S107). The vehicle status management unit 134 may perform control to stop transmission of the read signal by the wireless communication device 11 when the parking management information is not recorded in the storage unit. As a result, transmission of unnecessary radio signals from the ticket issuing machine 1 can be suppressed.

The RFID tag 4 provided on the parking ticket 3 receives the read signal transmitted by the wireless communication device 11 . The RFID tag 4 generates an electromotive force by a resonance action based on the reception of the radio wave of the reading signal, and transmits a tag signal including information to be stored by the electromotive force. The wireless communication device 11 receives the tag signal (step S108). The information acquisition unit 133 acquires information included in the tag signal from the wireless communication device 11 . The information may include the ticket issuing number, the ticket issuing time, the ticket issuing machine ID written in the RFID tag 4, and various other information.

The information acquisition unit 133 uses the reception information included in the tag signal received by the wireless communication device 11 to determine from which parking space the tag signal was transmitted (step S109). More specifically, the wireless communication device 11 has a plurality of antennas, and estimates the transmission position based on the phase difference and reception strength of the tag signal received by each antenna. The originating position may be the distance from the wireless communication device 11, for example. A known technique may be used for estimating the originating position. Based on the transmission position, the information acquisition unit 133 identifies the parking space where the RFID tag 4 that transmitted the tag signal is located. For example, if the ticket issuing machine 1 manages the parking spaces A1, A2, and A3, the information acquiring unit 133 determines whether the RFID tag 4 that has transmitted the tag signal is in any of the parking spaces A1, A2, and A3. Identify whether the tag signal was emitted from the location. This process is performed by the information acquisition unit 133 based on the reception status of the wireless signal carrying the information received from the RFID tag 4, which is a wireless transmitter, in the wireless communication device 11. This is one mode of processing for determining whether communication has been established with a wireless transmitter that is connected to a mobile station. The information acquisition unit 133 outputs an information acquisition result including the information contained in the acquired tag signal and the identification number of the identified parking space to the vehicle condition management unit 134 . The information acquisition unit 133 periodically outputs information acquisition results obtained under the control of the wireless communication device 11 to the vehicle condition management unit 134 .

The vehicle status management unit 134 acquires the ticket issue number and the ticket issue time from the information acquisition result. The vehicle status management unit 134 calculates the parking time from the difference between the time when the ticket was issued and the current time (step S110). The vehicle condition management unit 134 determines whether the parking time is longer than or equal to a predetermined parking available time (step S111). When the parking time is equal to or longer than the predetermined parking available time, the vehicle condition management unit 134 generates overtime information (step S112). The time-out information may include the ticket issuing number, ticket issuing time, and ticket issuing machine ID. The excess time information may include other information written on RFID tag 4 . The vehicle condition management unit 134 instructs the output unit 135 to transmit the overtime information. The output unit 135 transmits the warning information including the overtime information to the parking management server 5 (step S113).

The parking management server 5 receives the warning information including the time limit information (step S114). In the parking management server 5, the parking management unit 512 acquires the overtime information. When the parking management unit 512 acquires the overtime information, it transmits warning information including the overtime information to the management terminal 6 (step S115). The management terminal 6 outputs the ticket issuing machine ID and the ticket issuing time included in the overtime information on the screen. Based on the ticket issuing machine ID and the ticket issuing time displayed on the management terminal 6, the manager of the parking space goes to the ticket issuing machine indicated by the ticket issuing machine ID to confirm the parking space managed by the ticket issuing machine ID.

By the above processing, the manager can confirm the vehicles parked in the parking space for a predetermined parking time or more based on the information displayed on the screen of the management terminal 6. FIG. The manager had to go around the parking spaces in the area in order and check them. It is only necessary to go around and perform confirmation work, and management labor can be reduced.

Further, the parking management unit 512 of the parking management server 5 may notify the user of the vehicle that has been parked in the parking space for a predetermined parking time or longer based on the time overtime information. For example, it is assumed that the above-mentioned parking management information includes the e-mail address of the user of the vehicle. In this case, the parking management unit 512 acquires the ticket issuing machine ID, the ticket issuing number, and the ticket issuing time from the overtime information received from the ticket issuing machine 1, and specifies the parking management information including these information from the storage unit. The parking management unit 512 reads the e-mail address included in the identified parking management information. The parking management unit 512 transmits warning information including time limit information to the e-mail address. As a result, the warning information including the overtime information is transmitted to the user's portable terminal, and the user can grasp that the parking time has exceeded the starting parking time.

In the above-described processing, the information acquisition unit 133 of the ticket issuing machine 1 may use the reception information of the tag signal of the wireless communication device 11 to determine whether the tag signal is transmitted from a position on the ground surface. For example, the information acquisition unit 133 estimates the transmission position based on the phase difference and reception strength of the tag signal received by each antenna. If the direction indicated by the transmission position is an angle that faces the ground surface, the information acquisition unit 133 can determine that the tag signal has been transmitted from a position on the ground surface. In this case, the information acquisition section 133 outputs management discard information including the information contained in the tag signal to the vehicle condition management section 134 . If the tag signal is transmitted from the ground surface, there is a possibility that the parking ticket 3 equipped with the RFID tag that transmitted the tag signal has been discarded. The vehicle status management unit 134 acquires the ticket issuing machine ID, the ticket issuing number, and the ticket issuing time from the information included in the management discard information. The vehicle condition management unit 134 deletes the parking management information including these pieces of information from the storage unit. Also, the vehicle status management unit 134 transmits a request for discarding the parking management information to the parking management server 5 via the output unit 135 . The parking management server 5 deletes the parking management information stored in its own server based on the parking management information included in the discard request.

In addition, the vehicle status management unit 134 identifies the ticket issue number from among the information contained in the tag signal, and even though it is stored in its own storage unit, the vehicle status management unit 134 detects the ticket issue number that cannot be received for a certain period of time, such as 5 minutes or 10 minutes. may be deleted from the storage unit. As a result, the management of the vehicle originating from the parking space can be stopped.

The vehicle status management unit 134 of the ticket issuing machine 1 may transmit information indicating the availability of parking spaces to the parking management server 5 based on the information acquisition result acquired from the information acquisition unit 133 . For example, the vehicle condition management unit 134 detects the identification number of the parking space where the vehicle is parked based on the information acquisition result described above. Accordingly, the vehicle condition management unit 134 identifies the identification number of the parking space where no vehicle is parked. For example, in the example of FIG. 1, the vehicle status management unit 134 of the ticket issuing machine 1 that manages the parking spaces A1, A2, and A3 determines that no vehicles are parked in the parking spaces A2 and A3. The identification number of the parking space can be specified. In this process, the vehicle status management unit 134 determines whether the vehicle is present or absent based on the reception status of the wireless signal received by the wireless communication device 11 from the RFID tag 4, which is the wireless transmitter, among the plurality of parking spaces. This is an example of managing the parking status of the vehicle based on the vehicle presence/absence information. The vehicle status management unit 134 transmits the vacant status information including the identification numbers of the parking spaces to the parking management server 5 via the output unit 135 .

The parking management server 5 receives the availability information. The parking management unit 512 of the parking management server 5 stores the identification information of the parking spaces included in the availability information. The parking management unit 512 generates map information indicating the positions of these parking spaces with vacant parking spaces and list information of the identification information of the parking spaces, which can be viewed on the mobile terminal of the user via the Internet. You may make it transmit. In this case, the parking management server 5 has the function of a web server, and distributes map information and list information by the function of the web server.

With the above processing, the parking management system 100 can efficiently manage the conditions of vehicles in a plurality of parking spaces.

The above-described parking management system 100 has explained the processing in the case of managing the parking space on the shoulder of the road. However, the parking management system 100 may manage parking spaces other than roadside parking spaces. For example, the parking management system 100 includes a parking management device that manages multiple parking spaces instead of the ticket issuing machine 1 . The parking management device does not have the ticket issuing mechanism 12, but has the same functions as the ticket issuing machine 1 other than that. Instead of the ticket issuing machine 1, the parking management device may manage a plurality of parking spaces in the same manner as described above. For example, a parking space for taxis at a taxi rank may be managed to determine whether a taxi is parked at the parking space at the taxi rank. The parking management device may also calculate the number of vehicles parked in the parking space and provide the information to the parking management server 5 . The parking management server 5 may perform processing for dispatching taxis based on the number of taxis parked in the parking space.

A mode in which the vehicle condition management unit 134 is provided in the ticket issuing machine 1 in the parking management system 100 described above will be described. However, the configuration of the vehicle status management unit 134 may be provided in the parking management server 5 . In this case, the information acquisition unit 133 of the ticket issuing machine 1 transmits the acquired information to the parking management server 5 . Then, the parking management unit 512 of the parking management server 5 may perform the same processing as the vehicle condition management unit 134 does.

FIG. 6 is a third diagram showing an overview of the parking management system according to this embodiment.
The vehicle 2 may be equipped with a communication device 7 as shown in FIG. The communication device 7 may be built in an in-vehicle device such as a DSRC (Dedicated Short Range Communications) in-vehicle device. In the parking management system 100 described above, as a result of the wireless communication device 11 transmitting the read signal, the wireless communication device 11 receives the tag signal from the RFID tag 4 of the parking ticket 3, and the information acquisition unit 133 detects the information contained in the tag signal. are getting However, the user of the vehicle parked in the parking space inserts a card such as an ETC (Electronic Toll Collection System) card extracted from the communication device 7 into the insertion slot of the ticket issuing machine 1, and as a result, the write processing unit 131 of the ticket issuing machine 1 may write information on the card. In this case, the user brings the card back to the vehicle 2 and inserts it into the communication device 7 . When the communication device 7 receives the read signal from the wireless communication device 11 , it transmits a response signal including the information written in the card to the wireless communication device 11 . It is assumed that the communication device 7 is activated even while the vehicle 2 is stopped. Then, the wireless communication device 11 may receive this response signal, and the information acquisition section 133 may acquire information contained in the response signal. The information included in the response signal may be the ticket issuing number, the ticket issuing time, the ticket issuing machine ID, etc., in the same manner as the information written in the RFID tag 4 . That is, in this case, the processing flow is as follows.

FIG. 7 is a second diagram showing the processing flow of the parking management system.
Next, processing of the parking management system 100 will be described.
First, the user who has parked the vehicle 2 in the parking space inserts the ETC card extracted from the communication device 7 of the vehicle 2 into the ticket issuing machine 1 . At this time, the ticket issuing machine 1 accepts the insertion of money from the user (step S201). The ticket issuing processing unit 132 of the ticket issuing machine 1 calculates the total amount of money and determines whether the total amount is equal to or greater than a predetermined parking fee. If the total amount is equal to or greater than the predetermined parking fee, the ticket issuing processing unit 132 outputs a request for writing information to the ETC card to the writing processing unit 131 . The write processing unit 131 writes information to the ETC card (step S202). The ticket issuing machine 1 ejects the ETC card (step S203). The user obtains an ETC card from the ticket issuing port. The user reinserts the ETC card into the communication device 7 .

When the ejection of the ETC card is completed, the ticket issue processing unit 132 outputs to the vehicle condition management unit 134 information indicating completion of writing, a ticket issue number specifying the ETC card, and a ticket issue time. The vehicle status management unit 134 records the parking management information including the ticket issuing number, the ticket issuing time, and the ticket issuing machine ID in the storage unit such as the HDD 17 (step S204). The parking management information may further include other information written in the ETC card. Vehicle status management unit 134 outputs the parking management information to output unit 135 . The output unit 135 transmits the parking management information to the parking management server 5 (step S205). The parking management unit 512 of the parking management server 5 records the parking management information in a storage unit such as the HDD 54 (step S206).

The vehicle status management unit 134 outputs an information acquisition request to the information acquisition unit 133 when the parking management information is recorded in the storage unit. The information acquisition unit 133 controls the wireless communication device 11 to transmit a read signal based on the information acquisition request. The information acquisition unit 133 controls the wireless communication device 11 to transmit the reading signal at predetermined time intervals such as one minute intervals. The wireless communication device 11 transmits a reading signal based on the control from the information acquisition section 133 (step S207).

The communication device 7 receives the read signal transmitted by the wireless communication device 11 . Based on the reception of the read signal, the communication device 7 transmits a response signal including the information written from the ticket issuing machine 1 to the ETC card.

The information acquisition unit 133 uses the reception information included in the response signal received by the wireless communication device 11 to determine from which parking space the communication device 7 is parked (step S209). More specifically, the wireless communication device 11 has a plurality of antennas, and estimates the transmission position based on the phase difference and reception strength of response signals received by each antenna. Subsequent processing is the same as the processing of steps S110 to S115.

The communication device 7 itself can be carried outside the vehicle 2. The user carries the communication device 7 from the vehicle 2 to the front of the ticket issuing machine 1, and the ticket issuing machine 1 directly communicates with the communication device 7. The same information as the information written in the ETC card or RFID tag 4 may be written. In this case, the user returns the communication device 7 to the vehicle 2 and places it inside the vehicle. The communication device 7 placed inside the vehicle 2 may transmit a response signal to the ticket issuing machine 1 based on the reception of the read signal transmitted from the ticket issuing machine 1 .

The ticket issuing machine 1 may be a device capable of writing information to the RFID tag 4 attached to the parking ticket 3 and writing information to the ETC card or the communication device 7 .
