  The operation panel 28 has a function as a user interface for an attendant of the mechanical parking lot 10 or an operator who performs maintenance work of the mechanical parking lot 10. The operation panel 28 has a touch panel. The operation panel 28 is connected to the control device 30 and transmits a control signal to the control device 30 in accordance with an operation input to the touch panel, and receives a control signal from the control device 30 and receives information necessary for the touch panel. Is displayed. For example, when the switching instruction from the service operation to the maintenance operation is input to the touch panel, the operation panel 28 transmits a switching instruction signal to the maintenance operation to the control device 30. Further, for example, when the switching instruction from the maintenance operation to the service operation is input to the touch panel, the operation panel 28 transmits a switching instruction signal to the service operation to the control device 30.

  “Service driving” refers to a state in which the mechanical parking lot 10 is in normal operation and entry / exit into all the parking spaces 50 is possible. The “maintenance operation” is a mode for the operator to perform various inspections regarding the parking space 50, including inspection of various devices provided in the power supply parking space 52 in the parking space 50. Regarding the instruction to switch to the maintenance operation, in the maintenance operation, entry / exit to all the parking spaces 50 is basically prohibited. However, when only a specific parking space 50 is to be put into maintenance operation, that is, when information specifying the specific parking space 50 is included in the switching instruction signal to maintenance operation, entry / exit to the power supply parking space 52 is performed. Only is prohibited.

  FIG. 3 is a block diagram showing a power supply system from the power supply apparatus to the power supply system 40. The mechanical parking lot 10 further includes a main switch 34 and a plurality of individual switches 36. These switches are constituted by, for example, electromagnetic contactors. In the embodiment, since each storage shelf includes three power supply parking spaces 52, the mechanical parking lot 10 includes nine power supply parking spaces 52. Therefore, the mechanical parking lot 10 includes nine power supply systems 40. The main switch 34 is provided on a path between all of the nine power supply systems 40 and the power supply device. The individual switch 36 is provided corresponding to the power feeding system 40. Each individual switch 36 is provided on a path between the main switch 34 and each power supply system 40.

  When the main switch 34 is turned off, the power supply device and the power supply terminals of all the power supply systems 40 are electrically disconnected. Therefore, even if the power feeding terminal and the power receiving terminal of the power receiving unit included in the EV car pallet 100 are in mechanical contact, the power receiving terminal is electrically disconnected from the power supply device. When the individual switch 36 is turned off, the power supply device and the power supply system 40 corresponding to the individual switch 36 are electrically disconnected.

  FIG. 4 is a block diagram illustrating the function and configuration of the control device 30. Each block shown here can be realized by hardware such as a computer (CPU) (Central Processing Unit) and other elements and mechanical devices, and software can be realized by a computer program or the like. The functional block realized by those cooperation is drawn. Therefore, it is understood by those skilled in the art who have touched this specification that these functional blocks can be realized in various forms by a combination of hardware and software.

  The control device 30 includes a reception unit 60, a monitoring unit 62, a notification unit 64, and a switch control unit 66. The accepting unit 60 receives a control signal transmitted from the operation panel 28. When receiving the switching instruction signal to the maintenance operation and the switching instruction signal to the service operation from the operation panel 28, the receiving unit 60 transmits the contents to the switch control unit 66.

  The monitoring unit 62 monitors various devices provided in the parking space 50. For example, the monitoring unit 62 monitors the power supply system 40. Specifically, the monitoring unit 62 receives a current value of power supplied from the power supply system 40 from an ammeter (not shown) provided in the power supply system 40, and monitors whether charging has started. In addition, the monitoring unit 62 monitors whether or not the time during which the power supply system 40 supplies power (that is, the charging time) is within a predetermined time. When charging is not started or when the charging time exceeds a predetermined threshold, it is considered that an abnormality such as a contact failure or a malfunction of the power feeding system 40 has occurred. When detecting such an abnormality, the monitoring unit 62 generates an abnormality detection signal and transmits the abnormality detection signal to the notification unit 64 and the switch control unit 66. The abnormality detection signal may include information for identifying the parking space 50 in which an abnormality has occurred.

  When receiving the abnormality detection signal from the monitoring unit 62, the notification unit 64 generates a notification signal including a message notifying that an abnormality has occurred and transmits the notification signal to the operation panel 28. The notification signal may include information for identifying the parking space 50 in which an abnormality has occurred. The operation panel 28 displays information corresponding to the received notification signal on the touch panel. An attendant of the mechanical parking lot 10 can grasp that an abnormality has occurred by reading a message displayed on the touch panel.

  The switch control unit 66 controls the operation state, that is, on / off of each of the main switch 34 and the plurality of individual switches 36. When the switch control unit 66 receives a switching instruction signal for maintenance operation, the switch control unit 66 controls the main switch 34 to be turned off. The switch control unit 66 controls the individual switch 36 corresponding to the power supply system 40 in the power supply parking space 52 to be turned off when the information for designating the specific power supply parking space 52 is included in the switching instruction signal to the maintenance operation. To do.

  When the switch control unit 66 receives a switching instruction signal for service operation, the switch control unit 66 controls the main switch 34 and all the individual switches 36 to be turned on. The switch control unit 66 controls the individual switch 36 corresponding to the power supply system 40 of the power supply parking space 52 to be turned on when information specifying the specific power supply parking space 52 is included in the switching instruction signal to service operation. To do. When the switch control unit 66 is off, the main switch 34 is also turned on.

  When receiving the abnormality detection signal, the switch control unit 66 controls the main switch 34 to be turned off as in the case of receiving the switching instruction signal for the maintenance operation. In addition, when the information which specifies the electric power feeding parking space 52 which abnormality has contained in the abnormality detection signal, the switch control part 66 turns off only the individual switch 36 corresponding to the electric power feeding system 40 of the electric power feeding parking space. You may control.

Operation | movement of the mechanical parking lot 10 comprised as mentioned above is demonstrated.
Consider the operation when maintenance is performed. The operator operates the operation panel 28 and instructs switching to the maintenance operation. The operation panel 28 transmits a switching instruction signal to the control device 30. When receiving the switching instruction signal, the control device 30 controls the main switch 34 to be turned off. Thereby, the electric power feeding system 40 of all the electric power feeding parking spaces 52 is electrically disconnected from a power supply device. In this state, the worker performs maintenance of various devices provided in the parking space 50 in the parking space 50 including the power supply parking space 52. Since the main switch 34 is off at this time, the power supply terminal of the power supply system 40 in the power supply parking space 52 is electrically disconnected from the power supply device. Therefore, among the power receiving terminals of the first power receiving unit 104 or the second power receiving unit 106, the power receiving terminal of the power receiving unit that is not in contact with the power feeding terminal is also electrically disconnected from the power supply device. Therefore, even if the operator touches the power receiving terminal, no electric shock is caused. When the maintenance is completed, the operator operates the operation panel 28 and gives an instruction to switch to service operation. The operation panel 28 transmits a switching instruction signal to the control device 30. When receiving the switching instruction signal, the control device 30 controls the main switch 34 to be turned on.

  Note that the operator may designate the parking space 50 (particularly the power supply parking space 52) where the maintenance work is performed when operating the operation panel 28 to instruct the switching to the maintenance operation. In this case, the control device 30 controls the individual switch 36 corresponding to the power supply parking space 52 to be turned off.

  Next, an operation when an abnormality occurs in the power supply parking space 52 will be considered. When detecting an abnormality, the control device 30 controls the main switch 34 to be turned off as in the case of the maintenance operation. The control device 30 may control only the individual switch 36 corresponding to the power supply system 40 in the power supply parking space 52 where the abnormality is detected to be off. Thereby, at least the power supply terminal of the power supply system 40 in the power supply parking space 52 in which an abnormality has occurred is electrically disconnected from the power supply device. Control device 30 also displays a message indicating that an abnormality has occurred on the touch panel of operation panel 28. The staff member grasps that an abnormality has occurred by reading this message, and notifies the worker who performs the maintenance work. The worker performs countermeasures according to the abnormality in the power supply parking space 52 where the abnormality has occurred. At this time, at least the power supply terminal of the power supply system 40 in the power supply parking space 52 where an abnormality has occurred is electrically disconnected from the power supply device. Therefore, among the power receiving terminals of the first power receiving unit 104 or the second power receiving unit 106, the power receiving terminal of the power receiving unit that is not in contact with the power feeding terminal is also electrically disconnected from the power supply device. Therefore, even if the operator touches the power receiving terminal, no electric shock is caused. When the countermeasure is completed, the operator operates the operation panel 28 to instruct switching to service operation. The operation panel 28 transmits a switching instruction signal for service operation to the control device 30. Upon receiving this signal, the control device 30 controls all the switches to be turned on.

  According to the mechanical parking lot 10 which concerns on embodiment described above, the electric power feeding system 40 of all the electric power feeding parking spaces 52 is electrically disconnected from a power supply device by switching from a service driving | operation to a maintenance driving | operation. Therefore, the power receiving terminal of the power receiving unit included in the EV car compatible pallet 100 is naturally electrically disconnected from the power supply device. As a result, when the worker is performing the maintenance work, no electric shock is caused even if he / she contacts the power receiving terminal of the power receiving unit not connected to the power supply unit 44.

  Moreover, according to the mechanical parking lot 10 which concerns on embodiment, the electric power feeding system 40 of the specific electric power feeding parking space 52 can be electrically disconnected from a power supply device. In other words, the electrical connection between the power supply system 40 and the power supply device in the power supply parking space 52 that does not require maintenance is maintained. Thereby, the influence on the charge by maintenance can be minimized.

  Further, according to the mechanical parking lot 10 according to the embodiment, when an abnormality is detected, the service operation is switched to the maintenance operation, and the power supply system 40 of all the power supply parking spaces 52 or the power supply of the power supply parking spaces 52 in which an abnormality has occurred. System 40 is electrically disconnected from the power supply. When an abnormality occurs, the operator needs to perform work in the electric power supply parking space 52 in which an abnormality has occurred, so that at least the electric power supply system 40 of the electric power supply parking space 52 that performs the operation is provided so that the operator does not get an electric shock. Must be electrically disconnected from the power supply. On the other hand, in the embodiment, as described above, when an abnormality is detected, the power supply system 40 of the power supply parking space 52 where the abnormality has occurred is electrically connected to the power supply device without the operator operating the operation panel 28. Separated. Therefore, the labor of the operator can be reduced.

  Further, according to the mechanical parking lot 10 according to the embodiment, the operation panel 28 is provided outside the passenger compartment 12, that is, at a position physically separated from the parking space 50. The operator switches the driving state of the mechanical parking lot 10 by operating the operation panel 28. Therefore, the operator is physically away from the parking space 50 when switching the driving state, particularly when switching from the maintenance driving to the service driving. This prevents the operator from getting an electric shock when switching to service operation.

  The configuration and operation of the mechanical parking lot according to the embodiment have been described above. This embodiment is an exemplification, and it is understood by those skilled in the art that various modifications can be made to combinations of the respective constituent elements, and such modifications are also within the scope of the present invention.
