  In FIG. 1, although two tower parkings are shown, three or more buildings may be used. Moreover, in FIG. 1, although the tower type parking lot was shown, as long as the type of a parking lot is a mechanical parking lot, any type of parking lot may be used, for example, a puzzle type, an underground type It may be a mechanical parking lot such as a multistage type.

  Next, processing operations to be performed before using the parking lot control system shown in FIG. 1 will be described. Tower parkings 11 and 12 shown in FIG. 1 are provided, for example, near the workplace of a company, and are used to park company cars used by employees. Each employee carries an IC card in which an employee number is written. Further, it is assumed that an ETC (Electronic Toll Collection System) vehicle-mounted device or a DSRC (Dedicated Short Range Communication) vehicle-mounted device (hereinafter referred to as a vehicle-mounted device) is mounted on all the vehicles parked in the tower parking 11 and 12. The user of the company car obtains the vehicle-mounted device ID that can uniquely identify the vehicle-mounted device in advance, the pallet number of the tower parking 11 and 12 where the vehicle is to be parked, the employee number stored in the IC card, and the IC card number. In association with each other, it is registered in a registered vehicle master database (not shown) in the parking lot control control device 2. The pallet number is composed of an identification number (TP number) for identifying one of the two tower parkings and a pallet number (vehicle compartment number) of the tower parking.

  Next, with reference to FIGS. 2 and 3, the processing operation at the time of vehicle entry in the parking lot control system shown in FIG. 1 will be described. First, when the vehicle arrives at the parking lot entrance and enters the detection area of the DSRC antenna 31 (FIG. 2 (1)), the vehicle-mounted device ID is received by the DSRC antenna 31, and the parking lot control device 2 receives the vehicle-mounted device ID. The vehicle-mounted device ID is authenticated, and if the vehicle-mounted device ID is authenticated, the warehousing prohibition flag is turned off and stored in the registered vehicle master database in association with the received vehicle-mounted device ID (step S1). Then, the parking lot control device 2 determines whether or not the shutter is in a closed state (step S2), and transmits an open signal to the shutter control panel 72 if the shutter is closed. As a result, the shutter 71 is opened (FIG. 2 (1)). The driver confirms that there is no leaving vehicle, and enters the parking lot site by slow driving (FIG. 2 (2)). At this time, the vehicle warning lights 61 and 62 are both lit in blue, indicating that they can enter.

  Next, when the vehicle enters the detection area of the DSRC antenna 32 (entry call dedicated antenna), the vehicle-mounted device ID is received by the DSRC antenna 32, and the parking lot control device 2 authenticates the received vehicle-mounted device ID, If authenticated, a determination process is performed to determine whether or not to perform a warehousing call. Here, with reference to FIG. 6, a determination processing operation for determining whether or not to perform a warehousing call will be described. FIG. 6 is a flowchart showing a determination processing operation for determining whether or not to perform a warehousing call. First, when receiving the vehicle-mounted device ID (step S21), the parking lot control device 2 determines whether or not the received vehicle-mounted device ID is a registered vehicle (step S22). The warehousing prohibition flag information associated with the received vehicle-mounted device ID is acquired from the database (step S23). And the parking lot control apparatus 2 determines whether the acquired warehousing call prohibition flag is off (step S24). As a result of the determination, if the warehousing call prohibition flag is on, it is determined that the warehousing is performed, and the warehousing call is not performed. On the other hand, if the warehousing call prohibition flag is off, it is determined that the warehousing is performed, and the warehousing calling process is executed for the tower parking 11 and 12 (step S25).

  In the example shown in FIGS. 2 and 3, since the warehousing call prohibition flag is off, it is determined that the warehousing is performed, and the parking lot control device 2 performs the warehousing call procedure and adds it to the queue (step S4). And the parking lot control apparatus 2 specifies a TP number and a vehicle compartment number from vehicle equipment ID, and transmits a warehousing call (step S6). The driver moves the vehicle to the front of the tower parking 11, confirms the display contents of the operation panel 13 (the occupant compartment number) (FIG. 2 (3)), enters the vehicle (FIG. 2 (4)), and gets off the vehicle. Then, the operation panel 13 is operated to close the safety gate. When the parking lot control device 2 receives the safety gate closing signal of the tower parking 11 (step S7), the warehousing is completed. The driver enters the IC card over the card reader 23 (FIG. 2 (6)).

  Next, with reference to FIGS. 4 and 5, the processing operation at the time of vehicle exit in the parking lot control system shown in FIG. 1 will be described. First, when the driver holds the IC card over the card reader 23 (FIG. 4 (1)), the parking lot control device 2 receives the card ID and performs authentication (step S11). When the card ID is authenticated, the parking lot control device 2 performs an outgoing call procedure and adds it to the queue (step S12). Then, the parking lot control device 2 identifies the TP number and the vehicle compartment number from the card ID, transmits a delivery call (step S13), and lights the vehicle warning light 61 (the warning light of the tower parking 11) in red (shipping). (Step S14). The driver moves to the front of the tower parking 11 and confirms the content displayed on the operation panel 13 (the vehicle compartment number during delivery) (FIG. 4 (2)) and gets on the vehicle and exits (FIG. 4 (3)). Then, the operation panel 13 is operated to close the safety gate (FIGS. 4 (4) and (5)).

  Next, when receiving the safety gate closing signal of the tower parking 11, the parking lot control device 2 turns on the warehousing call prohibition flag (step S 15). When the vehicle moves and enters the detection area of the DSRC antenna 32 (entrance call dedicated antenna), the DSRC antenna 32 receives the vehicle-mounted device ID, and the parking lot control device 2 authenticates the received vehicle-mounted device ID, If it is authenticated, a determination process is performed to determine whether or not to perform a warehousing call (step S16). Here, the process operation shown in FIG. 6 is performed to determine whether or not to perform a warehousing call. Here, since the warehousing call prohibition flag is on, the warehousing call is not performed. The parking lot control device 2 transmits an instruction to turn on the exit warning lamp 51 (step S17), and turns on the vehicle warning lamp 61 in blue (step S18). When the vehicle further moves and enters the detection area of the DSRC 31 (FIG. 4 (6)), the vehicle-mounted device ID is received by the DSRC antenna 31, and the parking lot control device 2 authenticates the received vehicle-mounted device ID. If it is authenticated, the warehousing prohibition flag is turned off and stored in the registered vehicle master database in association with the received vehicle-mounted device ID (step S19). Subsequently, the parking lot control device 2 transmits an instruction to turn off the exit warning lamp 51 (step S20).

  In this way, the DSRC antenna is installed in the parking lot, the unique OBE ID of the OBE is read, the entrance / exit determination is automatically performed without installing the gate and the lane separation, and the shutter interlock control, the three-dimensional parking In the parking lot system that performs the parking lot interlocking control, when entering the tower parking, the vehicle-mounted device ID is acquired by the DSRC antenna dedicated to the warehousing call, and the tower parking pallet is automatically called. Since one DSRC antenna cannot determine the traveling direction of the vehicle, the state of the vehicle delivered from the tower parking is managed and solved by a host device. Specifically, during the exit from the parking lot after the completion of TP delivery, a “receipt call prohibition flag” is provided so as not to execute an entry call even if it passes through the DSRC antenna, and this is stored and managed for each registered vehicle. To do. This flag information is set (ON) when the tower parking is completed for each vehicle, and the vehicle is detected by another DSRC antenna immediately before exiting the parking lot and reset (OFF), so that warehousing is called while driving toward exit Even if it passes through the DSRC antenna for a plurality of times, the warehousing call does not occur. At the time of warehousing, the flag information can be reset (OFF) again by the DSRC antenna, so that the warehousing call process can be surely executed by the DSRC antenna.

  Thereby, it becomes a simple structure without a gate, and the parking lot where the freedom degree of a layout improves can be provided. Further, since the vehicle can be detected only by the DSRC antenna, it is not necessary to install another sensor, and cost reduction can be realized. In addition, since the pallet of the tower parking can be automatically called at the time of warehousing, it is possible to save labor and shorten the waiting time until the pallet arrives. Furthermore, the security of the parking lot can be enhanced by shutter-linked control based on entry / exit determination and registered vehicle authentication.

  The program for realizing the function of the parking lot control device 2 in FIG. 1 is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read by the computer system and executed. A parking lot control process may be performed. Here, the “computer system” includes an OS and hardware such as peripheral devices. The “computer system” includes a WWW system having a homepage providing environment (or display environment). The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Further, the “computer-readable recording medium” refers to a volatile memory (RAM) in a computer system that becomes a server or a client when a program is transmitted via a network such as the Internet or a communication line such as a telephone line. In addition, those holding programs for a certain period of time are also included.

  The program may be transmitted from a computer system storing the program in a storage device or the like to another computer system via a transmission medium or by a transmission wave in the transmission medium. Here, the “transmission medium” for transmitting the program refers to a medium having a function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line. The program may be for realizing a part of the functions described above. Furthermore, what can implement | achieve the function mentioned above in combination with the program already recorded on the computer system, what is called a difference file (difference program) may be sufficient.

  It can be applied to applications where it is indispensable to detect a vehicle by wireless communication and perform a control operation in a parking lot.
