Then, by appropriately traversing each lower pallet 17, any one lifting pallet 11, 12, 13 located in the upper parking area T 4 or any one middle stage located in the middle parking area T 2 (5). The landing position P1 in the lower parking area T1 can be secured for the pallet 15.

  In the underground parking area T0, there are a plurality of underground pallets 19 (three in this case) that can be moved up and down between the ground stop position defined in the lower parking area T1 and the underground landing position defined in the underground parking area T0. ) Is provided. For each underground pallet 19, an elevating mechanism (not shown) for giving the underground pallet 19 an up-and-down movement operation is provided. This lifting mechanism is known per se and includes, for example, a drive motor. The ground stop position of each underground pallet 19 is determined to be the same as the landing position P1 in the lower parking area T1 of the lifting pallets 11, 12, 13 for example.

  As described above, the parking apparatus 1 has a total of 12 pallets including three lifting pallets 11, 12, 13, 4 middle pallets 15, 2 lower pallets 17, and 3 underground pallets 19. Each pallet has a unique pallet number (for example, No. 1 to No. 12) and is distinguished from each other.

  In addition, in order to improve safety when the parking device 1 is operating, the parking device 1 prevents a person from entering the parking device 1 and prevents a person or the like from falling into the basement. In addition, a gate 21 is provided at the vehicle entrance / exit Q1.

A so-called non-contact type IC card reader that reads information stored in the card 91 is used. The card reading unit 25 transmits an electrical signal indicating that the IC card 91 has been detected to the overall control unit 37 (described later) when the IC card 91 is within a predetermined distance range in which communication is possible. The display unit 29 is controlled by the display control unit 49, and displays the pallet number in the information read from the IC card 91, the operation state of the parking device 1, and the like. The warning lamp 27 lights up or blinks in a predetermined case to display the operation state around. The emergency stop button 33 stops the operation of the parking apparatus 1 when operated by a user in an emergency, for example. The instruction input unit 31 is an input device including a numeric keypad, and accepts an input by the user in a predetermined case where a user instruction is required. When the parking device 1 is in the operation lock state, the lock release button 34 is operated by the user to release the operation lock state. The operation locked state is a state in which the operation of the user by the operation panel 23 is not accepted so that the pallets 11 and the like and the gate 21 do not move accidentally while the user enters and leaves the vehicle. In the operation lock state, the movement of each pallet 11 and the like and the movement of the gate 21 are prohibited regardless of the input from the operation panel 23.

  On the rear surface of the parking apparatus 1, a pallet driving motor for driving each pallet, a gate driving motor for driving the gate 21, and a control panel 35 for controlling the operation of the operation panel 23 are provided on the ground surface G. It is arranged in a state of facing.

  FIG. 4 is a block diagram illustrating a control configuration of the parking apparatus 1. The control panel 35 has a control CPU (not shown) including ROM and RAM, for example.

The display control unit 49, the motor control unit 50, and the like are included.

  The motor control unit 50 includes a pallet driving motor 61 for the lifting mechanism for each lifting pallet 11, 12, 13 and a pallet driving motor 61 for the lifting mechanism for each middle pallet 15 or lifting / lowering via a control system signal line (not shown). It is connected to the pallet drive motor 61 of the mechanism, the pallet drive motor 61 of the drive mechanism for each lower pallet 17, the pallet drive motor 61 of the lift mechanism for each underground pallet 19, or the gate drive motor 63 of the lift mechanism for the gate 21. A drive control signal for controlling the drive state of each drive motor is supplied to each pallet drive motor 61 and gate drive motor 63. The motor control unit 50 and the pallet drive motor 61 function as pallet drive means. The motor controller 50 and the gate drive motor 63 function as gate drive means. The motor control unit 50, the pallet drive motor 61, and the gate drive motor 63 are controlled and operated by the overall control unit 37, and the overall control unit 37 functions as a control unit that controls the pallet drive unit and the gate drive unit.

  The card reading unit 25 is connected to the overall control unit 37 via the communication control unit 43. The card reading unit 25 is controlled by the communication control unit 43 to exchange data with the IC card 91. The display unit 29 and the warning lamp 27 are connected to the overall control unit 37 via the display control unit 49. The display unit 29 is controlled by the display control unit 49 and displays predetermined information. The warning lamp 27 is controlled by the display control unit 49, and displays lighting or blinking in a predetermined case. The limit switch 24, the emergency stop button 33, the lock release button 34, and the instruction input unit 31 are connected to the overall control unit 37 via the input control unit 47. The limit switch 24 transmits a control signal to the overall control unit 37 when the gate 21 contacts. The emergency stop button 33 transmits a control signal to the overall control unit 37 when operated by the user. The overall control unit 37 that has received this control signal transmits a control signal to the motor control unit 50 and stops the pallet drive motor 61 and the gate drive motor 63. The unlock button 34 transmits a control signal to the overall control unit 37 when operated by the user. The overall control unit 37 that has received this control signal releases the operation lock state. The instruction input unit 31 transmits a control signal corresponding to the operation to the overall control unit 37 when operated by the user. The overall control unit 37 that has received the control signal according to the user's operation transmits the control signal to the motor control unit 50 and drives the pallet drive motor 61 and the gate drive motor 63 according to the user's operation.

  As the IC card 91, for example, a so-called non-contact type IC card is used. The IC card 91 has a data storage unit 93 and a communication unit 95. The IC card 91 is normally held by the user of the parking device 1, and a pallet number is stored in the data storage unit 93 as information regarding a desired pallet. In the present embodiment, the data storage unit 93 stores a user ID in addition to the palette number. The user ID is ID data for identifying a user who uses the parking apparatus 1 and is information unique to each user. The pallet number is information relating to the pallet used by the user holding the IC card 91 and is data indicating which pallet the user uses (for example, No. 1 to No. 12). This pallet number is stored in correspondence with the pallet number assigned to each pallet of the parking apparatus 1. The communication unit 95 communicates information with the card reading unit 25. Information stored in the data storage unit 93 is transmitted to the parking device 1 side via the communication unit 95.

  A single pallet to be used can correspond to a plurality of IC cards. That is, in these sets of IC cards, the stored user IDs are different from each other, but the pallet numbers are the same. For example, when a pallet is shared by a plurality of users, each user holds an IC card group as described above. On the other hand, since the user ID is a unique number for each user as described above, the user ID is operated so that there is no set of cards having the same user ID. For this reason, for example, when the read user ID is the same for the IC card read in the step of moving the pallet (described later) and the IC card read in the step of closing the gate 21 (described later) It can be determined that both IC cards are the same.

  Further, for example, if the user's home key is an IC card type key and the home key is set in accordance with the communication protocol, data system, etc. of the IC card 91, the home key is set in the IC card 91. It is possible to operate the key and the key function of the parking apparatus 1 together. Further, the data storage unit 93 may store other information such as personal information of the user.

  FIG. 5 is a flowchart of the vehicle entry / exit processing in the parking apparatus 1. The entering / exiting process of the parking apparatus 1 and the user's operation will be described with reference to this figure.

  First, a user who wants to enter and leave the vehicle brings the IC card 91 into contact with the card reading unit 25 of the parking device 1. In the parking apparatus 1 in the standby state (S202), the card reading unit 25 detects the IC card 91 (S204), the power is turned on, and the user ID stored in the data storage unit 93 from the card reading unit 25 and The pallet number is read (S206). Then, the data stored in the specification data storage unit 41 is compared with the read user ID and pallet number, and the validity of the IC card 91 is checked (S208). In this validity check, for example, whether the user ID is correct data, whether the user has authority to operate the parking apparatus 1, and whether the pallet number is a pallet that exists in the parking apparatus 1. It is confirmed. At this time, if it is determined that the read user ID or pallet number is invalid, it is considered that the IC card 91 is not a valid card and the card holder is not authorized to operate the parking device 1. Then, the process returns to the standby state of S202.

  If it is determined in S208 that the IC card 91 is a valid card, the pallet driving motor 61 is driven and the movement of the pallet is started (S216). This pallet movement is performed in a predetermined order to move the pallet (desired pallet) corresponding to the pallet number read from the IC card 91 to the landing position P1 (entry / exit position) in the lower parking area T1. Done. At this time, the pallet to be moved to the landing position P1 may be moved to any landing position P1 among the plurality of lower parking areas T1. During the pallet movement, the user ID, the pallet number, and a predetermined message read from the IC card 91 may be displayed on the display unit 29. After the movement of the pallet to the landing position P1 is completed, the gate drive motor 63 is driven to open the gate 21 (S218). Then, after it is detected by the limit switch 24 that the gate 21 is completely opened (S222), the parking apparatus 1 is set in the operation locked state (S224) and waits until the lock release button 34 is operated (S226). ).

  As described above, the parking apparatus 1 can read the pallet number stored in the IC card 91 by the card reading unit 25, and the overall control unit 37 can receive the pallet number without requiring the user to input a key for the pallet number. The pallet number to be moved to the floor position P1 can be directly recognized. Therefore, a user who wants to enter / exit the vehicle moves the desired pallet to the landing position P1, opens the gate 21 and locks the operation by only the operation of bringing the IC card 91 into contact with the card reading unit 25. A series of preparations for loading and unloading can be performed automatically.

  Thereafter, while the parking apparatus 1 is in the operation locked state, the user enters the vehicle C into the pallet at the landing position P1 or leaves the vehicle C from the pallet at the landing position P1. When entering the vehicle C, the user enters the pallet moved to the landing position P1 together with the vehicle C, and then gets off the vehicle C and leaves the parking device 1. Further, when leaving the vehicle C, the user enters the parking device 1, gets on the vehicle C on the pallet moved to the landing position P <b> 1, and exits the parking device 1 together with the vehicle C. .

  Since it is dangerous if the pallet 11 or the like or the gate 21 moves accidentally during such loading / unloading, the parking apparatus 1 is automatically set to the operation locked state as described above. Yes. This operation lock controls the movement of the pallet 11 and the gate 21 and the like when the vehicle is in and out, so that the user can safely enter and leave the vehicle. It should be noted that while the operation is locked, the display unit 29 may display that the operation is locked, and the warning lamp 27 may be turned on in order to allow the user to confirm the fact. Good.

  Subsequently, the user who has finished loading and unloading the vehicle operates the lock release button 34 (for example, presses the button) of the operation panel 23. In the parking apparatus 1, the operation of the unlock button 34 is detected (S226), and the operation lock state is released (S228). In this way, by operating the lock release button 34 when releasing the operation lock state, the user can be aware that the parking apparatus 1 will move to the next operation, and can be urged to confirm safety.

  After releasing the operation lock state, the user brings the IC card 91 into contact with the card reading unit 25 again. In the parking apparatus 1, it is confirmed that the detected IC card is the same as the card used in the previous S204 (S232), and the gate drive motor 63 is driven to close the gate 21 (S234). Then, after the gate 21 is closed (S236), a message indicating that the loading / unloading is completed is displayed on the display unit 29 (S238), the power is turned off, and the process returns to the standby state (S202). In addition, after the gate 21 is completely closed (after S236), a process for requesting the IC card 91 to be brought into contact with the card reading unit 25 again may be added. In this way, it is possible to prevent the user from leaving before the gate 21 is fully closed, so that safety can be improved. At this time, if the IC card 91 is not touched, a process for making the user's IC card 91 unusable from the next time is performed as a penalty for the user's failure to confirm safety. Also good.

  In addition, when the operation of the emergency stop button 33 is detected during the loading / unloading process, the pallet driving motor 61, the gate driving motor 63 and the like are stopped for safety.

  As described above, according to the parking device 1, it is possible to enter and leave the vehicle without requiring a complicated operation by the user.

  In the above embodiment, the present invention is applied to the up-and-down traverse type parking apparatus 1. However, the present invention is not limited thereto, and can also be applied to an up-and-down type parking apparatus and a tower-type parking apparatus.

It is a front view which shows a parking apparatus. It is a side view which shows a parking apparatus. It is a perspective view of an operation panel. It is a block diagram which shows the control structure of a parking apparatus. It is a flowchart of the entering / exiting process of the vehicle in a parking apparatus.
