Embodiments for Carrying Out the Invention

[0012] 〔First Embodiment〕 Hereinafter, a power supply control system, a power supply control method, a power supply control program, and a mechanical parking device according to the first embodiment of the present disclosure will be described with reference to the drawings. In the first embodiment described below, an elevator-type tower mechanical parking device is exemplified as the mechanical parking device of the present disclosure, but it is not limited to this example. The mechanical parking device of the present disclosure may be a vertical circulation type, a plane reciprocating type, a horizontal circulation type, a two-multistage type, or the like. Further, it may be a conveyor type or a fork type mechanical parking device that does not use a pallet.

[0013] FIG. 1 is a longitudinal sectional view of a mechanical parking device 1 according to the first embodiment of the present disclosure. As shown in FIG. 1, the mechanical parking device 1 is an elevator-type tower multi-story parking facility capable of accommodating a plurality of vehicles 2, and includes a parking tower 5 provided with an entrance / exit 3 and an entrance / exit door 4. The ground floor of the parking tower 5 is a landing 7 for loading and unloading the vehicle 2, and a turntable 8 for changing the direction of the vehicle 2 is installed on the floor surface thereof. The turntable 8 has a configuration in which a swivel plate 10 and a swivel drive unit 11 are provided in a concave pit 9 formed on the floor surface of the landing 7. In this embodiment, the case where both loading and unloading are performed in the landing 7 is shown, but it is not limited thereto. For example, the landing may be made different for loading and unloading, and a loading-only landing and a unloading-only landing may be provided. Further, in this embodiment, one landing is shown, but a plurality of landings may be provided.

[0014] A vertical lifting passage 13 is formed in the central portion of the parking tower 5, and a lift 14 (an elevator-like transporter) is provided in this passage so as to be able to move up and down. The lift 14 is suspended at its four corners by a plurality of wire ropes extending downward from a winch (not shown) provided, for example, at the upper part of the parking tower 5, and can move up and down in the lifting passage 13 when the winch is activated.

[0015] On the other hand, vehicle storage racks 17 (parking spaces) are provided on both sides of the elevator passage 13. These vehicle storage racks 17 are arranged in a multi-tiered manner, vertically flanking the elevator passage 13, and each vehicle storage rack 17 houses one pallet 18 for loading vehicles. Note that the support columns and other components of the vehicle storage racks 17 are not shown in the illustration.

[0016] The floor surfaces of the lift 14 and the vehicle storage rack 17 are provided with a transfer mechanism (not shown) that allows for the smooth transfer of an empty pallet 18 or a pallet 18 loaded with a vehicle 2 from the lift 14 to the vehicle storage rack 17, or from the vehicle storage rack 17 to the lift 14, when the heights of the floor surfaces of both are aligned.

[0017] Figure 2 is a schematic perspective view showing the passenger compartment 7. Inside the passenger compartment 7, there is a space in the center where a pallet 18 is placed, and on the wall in front of the entrance / exit door 4, there is a mirror 24 for the driver (user) to check the position of the vehicle 2, and an illuminated stopping position indicator light 25 that provides guidance for "forward," "stop," and "reverse." Near the entrance / exit door 4, a door fully open detection sensor 66 is provided to detect when the entrance / exit door 4 is fully open, and a door fully closed detection sensor 67 is provided to detect when the entrance / exit door 4 is fully closed.

[0018] The passenger compartment 7 is equipped with four cameras 35A to 35D to photograph the interior. In this embodiment, cameras 35A to 35D are, for example, video cameras, and each is mounted on a different wall (4 sides) of the passenger compartment 7. The number of cameras to be installed is not limited to the above; at least one camera is sufficient.

[0019] The passenger compartment 7 is equipped with an internal detection sensor (internal detection means) 30 (see Figure 5) for detecting people (objects) inside the passenger compartment. The internal detection sensor 30 may include sensors for detecting people (objects) in each of the following areas of the passenger compartment 7: the front area, the right side area, the left side area, and the rear area. Known sensors can be appropriately used as these sensors. Examples include human presence sensors and photoelectric sensors. The internal detection sensor 30 may also include a vehicle presence sensor 31 for detecting that a vehicle is inside the passenger compartment, and a vehicle position detection sensor for detecting the vehicle's stopped position. Furthermore, the internal detection sensor 30 may include, for example, two range sensors 30A and 30B located diagonally opposite each other in the passenger compartment 7.

[0020] Figure 3 shows an example of the installation position and detection range of the range sensors 30A and 30B in the passenger compartment 7. The range sensors 30A and 30B output a search wave W that has the property of reflecting off a target object, such as a laser beam or ultrasonic wave, and by receiving the reflected wave and scanning a predetermined angular range horizontally, they can detect people in the passenger compartment, the presence or absence of a vehicle, and so on.

[0021] Furthermore, the cameras 35A to 35D mentioned above can be used as the internal detection sensor 30. In this case, it is possible to confirm that the passenger compartment is unoccupied based on the image data acquired by the cameras 35A to 35D. The internal detection sensor 30 is used to check for unoccupied passengers inside the passenger compartment and is not limited to the various sensors described above. The various sensors described above may be used in combination, or other known sensors may be used as appropriate.

[0022] As shown in Figure 2, an entry / exit detection sensor 32 may be provided at the entrance / exit 3 of the passenger compartment 7 to detect when a person or vehicle enters or exits the passenger compartment 7. Furthermore, the passenger compartment may be equipped with an information unit (notification means: not shown) for notifying users of information (guidance information for entering and leaving the depot, error information, etc.) by voice. Examples of the notification unit include speakers and warning lights.

[0023] Outside the passenger compartment 7, an entry control light 21 with blue and red lamps is installed above the entry / exit door 4. Also outside the passenger compartment 7, an operation panel 22 is installed to receive input information for closing the entry / exit door 4. The operation panel 22 is operated by, for example, users, administrators, maintenance personnel, etc. A monitor 28 for displaying real-time images captured by cameras 35A to 35D is installed near the operation panel 22. Furthermore, the passenger compartment 7 is equipped with an emergency door 6 for workers to enter and exit in emergencies or during maintenance, and an emergency door fully closed detection sensor 36 is provided nearby to detect when the emergency door 6 is open, or in other words, to detect when the emergency door 6 is not fully closed.

[0024] Furthermore, a parking control device 40 that controls the entire mechanical parking system 1 is installed inside or outside the passenger compartment 7. The mechanical parking system 1 is also equipped with an electrical control system 80 (see Figure 6), which will be described later.

[0025] Figure 4 shows an example configuration of the control panel 22. As shown in Figure 4, the control panel 22 is housed in a metal casing 43 for protection from wind and rain and to prevent tampering, and this casing 43 is equipped with a lockable lid 44. When an operator operates the control panel 22, they unlock the lid 44 and open it to access the control panel 22.

[0026] The control panel 22 includes, for example, an authentication information input unit for receiving user authentication information. In this embodiment, an IC card reader 46 is provided as an example of the authentication information input unit, but the system is not limited to this example. The authentication information input unit may consist of, for example, a biometric information reading unit that reads so-called biometric authentication information such as a keypad, fingerprint, iris, vein information, or facial image, and a wireless communication unit that receives authentication information via wireless communication (e.g., 3G, 4G, 5G, 6G, wireless LAN, Wi-Fi, LTE, etc.).

[0027] The control panel 22 may also be equipped with a touch panel 45, a speaker 47 for providing voice instructions to the operator (e.g., a user), an emergency stop button 48 for emergency stopping the operation of the mechanical parking device 1, a microphone, and the like.

[0028] The touch panel 45 combines display and input functions. For example, the touch panel 45 displays various guidance information for performing parking entry and exit operations, as well as operation buttons for the operator to perform these operations. The display on the touch panel 45 is controlled by the parking control device 40, which will be described later, and the information entered when the touch panel 45 is operated by the operator is output to the parking control device 40.

[0029] Figure 5 is a functional block diagram showing an example of the functions of the parking control device 40 of the mechanical parking system 1 according to this embodiment. The parking control device 40 is, for example, an information processing device and includes a CPU, an auxiliary storage device for storing programs executed by the CPU, a main memory that functions as a work area when each program is executed, a communication interface for connecting to a network, and so on. The parking control device 40 also includes a comprehensive database 52 that stores various data necessary for controlling the mechanical parking system 1. The comprehensive database 52 stores vehicle occupancy status, pallet shape type, vehicle storage shelf shape type, identification information of persons authorized to use the mechanical parking system 1, and contact information of users, etc. (for example, registered email address, etc.). Persons authorized to use the mechanical parking system 1 include users, administrators, maintenance personnel, etc.

[0030] Furthermore, the parking control device 40 is equipped with a storage unit 41 for storing necessary data in conjunction with the execution of the parking entry and parking exit processes described later. For example, the storage unit 41 stores the user ID (first authentication information) obtained when user authentication was successful in the first user authentication process, information on various modes, and so on.

[0031] The auxiliary storage device of the parking control device 40 stores control programs and other information for controlling each mechanism of the mechanical parking device 1. The CPU reads the various programs stored in the auxiliary storage device into the main memory and executes them to realize the functions of each part described later. In executing the programs, the CPU also refers to and uses various data stored in the integrated database 52.

[0032] The control program described above may be pre-stored in an auxiliary storage device such as ROM during the manufacturing of the parking control device 40, or it may be downloaded and installed from a server that distributes control programs after installation. It may also be installed via an external storage device. Thus, there are no particular limitations on the method of installing the various programs.

[0033] The parking control device 40 includes a main control unit 50. In addition to the comprehensive database 52 mentioned above, the main control unit 50 is connected to an entrance / exit door control unit 55, a transporter control unit 56, a sensor control unit 57, a camera control unit 58, an image database 59, a vehicle measurement control unit 61, a turning control unit 62, and the like. Furthermore, an operation panel 22 is connected to the main control unit 50, enabling two-way communication.

[0034] The entry / exit door control unit 55 receives an operation command from the main control unit 50 and controls the door drive unit 63, which drives the entry / exit door 4 to open and close, thereby opening and closing the entry / exit door 4. The entry / exit door control unit 55 also receives a position signal of the entry / exit door 4 from the entry / exit door sensor 65 and feeds this information back to the main control unit 50. The door drive unit 63 is configured, for example, with a motor or the like. Various known configurations can be appropriately adopted for the door drive unit 63.

[0035] The entry / exit door sensor 65 includes, for example, a fully open door detection sensor 66 that detects when the entry / exit door 4 is fully open, and a fully closed door detection sensor 67 that detects when the entry / exit door 4 is fully closed. Any known sensor can be appropriately used as the entry / exit door sensor 65. Examples of the fully open door detection sensor 66 and the fully closed door detection sensor 67 include limit switches.

[0036] The door fully open detection sensor 66 outputs a fully open detection signal (e.g., an ON signal) when the door is fully open, and outputs a fully open release signal (e.g., an OFF signal) when the entry / exit door 4 is not fully open. The door fully closed detection sensor 67 outputs a fully closed detection signal (e.g., an ON signal) when the door is fully closed, and outputs a fully closed release signal (e.g., an OFF signal) when the entry / exit door 4 is not fully closed. The detection signals from the door fully open detection sensor 66 and the door fully closed detection sensor 67 are also output to the power supply control system 80, which will be described later.

[0037] The conveyor control unit 56 controls the raising and lowering of the lift 14 and the loading and unloading of the pallets 18 by controlling the lift drive unit 64, which drives the lift 14, in response to an operation command from the main control unit 50. The conveyor control unit 56 also receives a position signal of the lift 14 from the conveyor position sensor 68 and feeds this information back to the main control unit 50.

[0038] The sensor control unit 57 receives the detection signal from the internal detection sensor 30 and outputs this information to the main control unit 50. The sensor control unit 57 also determines the entry or exit of a person or vehicle based on the detection signal from the entry / exit detection sensor 32 and outputs the determination result to the main control unit 50. The sensor control unit 57 also receives the detection signal from the landing detection sensor 34 and outputs this information to the main control unit 50. Here, the landing detection sensor 34 is a sensor that detects, for example, when the lift 14 has landed on the boarding / alighting room (entry floor) 7. The landing detection sensor 34 outputs a landing detection signal (e.g., an ON signal) when the lift 14 is in a landing state, and outputs a landing release signal (e.g., an OFF signal) when the lift 14 is not in a landing state. The detection signal from the landing detection sensor 34 is also output to the power supply control system 80, which will be described later. Examples of landing detection sensors 34 include cage landing detection devices commonly found in mechanical parking systems (see, for example, Japanese Patent Application Publication No. 2006-307495).

[0039] The camera control unit 58 receives an operation command from the main control unit 50 and causes the cameras 35 (35A~35D) installed inside the passenger compartment 7 to capture images, and outputs the image information to the main control unit 50. This image information is stored in the image database 59 for a predetermined period. The image database 59 may be located inside the integrated database 52 or on the cloud.

[0040] The vehicle measurement control unit 61 receives an operation command from the main control unit 50, measures the weight of the vehicle mounted on the lift 14 using the vehicle measuring instrument 69, and feeds this information back to the main control unit 50 via the vehicle weight sensor 72. This vehicle weight information is used for controlling the lift 14, etc.

[0041] The rotation control unit 62 receives an operation command from the main control unit 50 and operates the turntable 8 by controlling the rotation drive unit 11 that rotates the turntable 8. The rotation control unit 62 also receives a rotation position signal of the turntable 8 from the turntable position sensor 71 and feeds this information back to the main control unit 50.

[0042] The main control unit 50 operates the mechanical parking system 1 based on feedback from each control unit 55, 56, 57, 58, 61, and 62, and input information from the control panel 22. The main control unit 50 also executes control programs for vehicle entry and vehicle exit based on various information exchanged with the control panel 22. The detection signals from the internal detection sensor 30, entry / exit detection sensor 32, and landing detection sensor 34 may be input directly to the main control unit 50 instead of being input to the main control unit 50 via the sensor control unit 57 described above. This makes it possible to implement faster control in response to the detection signals.

[0043] Figure 6 is a diagram showing one example configuration of the power supply control system 80 according to this embodiment. As shown in Figure 6, the power supply control system 80 includes a switch 81 and a power supply control unit (power supply control means) 82.

[0044] Power is supplied from a power supply 70 to the door drive unit 63 that drives the loading / unloading door 4 and the conveying equipment drive unit 60 that drives the conveying equipment. A switch 81 is provided in the circuit connecting the door drive unit 63 and the conveying equipment drive unit 60 to the power supply 70. The conveying equipment includes a lift 14. The conveying equipment may also include a turntable 8. The conveying equipment drive unit 60 includes a lift drive unit 64 that drives the lift 14. The conveying equipment drive unit 60 may also include a slewing drive unit 11 that drives the turntable 8.

[0045] The switch 81 controls the power supply to the door drive unit 63 and the transport equipment drive unit 60. The switch 81 is a mechanical switch that switches between powering on and cutting off power to the door drive unit 63 and the transport equipment drive unit 60, and examples include a magnetic contactor and a magnetic switch. The opening and closing of the switch 81 is controlled by the power supply control unit 82.

[0046] The power supply control unit 82 is, for example, an information processing device and includes a CPU, an auxiliary storage device for storing programs executed by the CPU, a main memory that functions as a work area when each program is executed, and a communication interface for sending and receiving information with other devices. The auxiliary storage device of the power supply control unit 82 stores power supply control programs for controlling the opening and closing of the switch 81, and the CPU reads the programs stored in the auxiliary storage device into the main memory and executes them to realize the various processes described later.

[0047] The above-mentioned power supply control program may be pre-stored in an auxiliary storage device such as ROM during the manufacturing of the power supply control system 80, or it may be downloaded and installed from a server that distributes the program after installation. It may also be installed via an external storage device. Thus, there are no particular limitations on the method of installing the various programs.

[0048] For example, when the power supply control unit 82 detects that the loading / unloading door 4 is not fully closed and the transport equipment is not in a loaded state during loading or unloading, it opens the switch 81 to cut off the power supply to the door drive unit 63 and the transport equipment drive unit 60. Specifically, the power supply control unit 82 opens the switch 81 when it receives a landing release signal (e.g., an off signal) from the landing detection sensor 34 and a fully closed release signal (e.g., an off signal) from the door fully closed detection sensor 67.

[0049] In the electrical circuit connecting the power supply 70, the door drive unit 63, and the transport equipment drive unit 60, a circuit breaker 73 may be provided upstream of the switch 81. In the electrical circuit connecting the power supply 70 and the door drive unit 63, a circuit breaker 74 may be provided downstream of the switch 81. In the electrical circuit connecting the power supply 70 and the transport equipment drive unit 60, a circuit breaker 75 may be provided downstream of the switch 81. The parking control device 40 is supplied with power from the power supply 70. A circuit breaker 76 may be provided in the circuit connecting the power supply 70 and the parking control device 40.

[0050] In the event of an overcurrent or other abnormality, circuit breakers 73-76 are activated, cutting off the power supply to the door drive unit 63, the transport equipment drive unit 60, and the parking control device 40. After safety is confirmed by the workers, circuit breakers 73-76 are reset, and power is restored.

[0051] [Inbound processing] Next, an example of the parking process performed by the parking control device 40 when a vehicle enters the parking lot will be explained with reference to the figures. Figures 7 to 9 are flowcharts showing an example of the procedure for the parking process performed by the parking control device 40.

[0052] First, when entering the parking lot, the user moves vehicle 2 in front of the entrance / exit gate 3, gets out of the vehicle, and approaches the control panel 22. Then, they unlock the lock with a special key and open the cover 44 of the housing 43. When the parking control device 40 detects that the cover 44 has been opened (SA1 in Figure 7), it displays the first user authentication screen on the touch panel 45 of the control panel 22 (SA2).

[0053] When a user touches their IC card to the IC card reader 46, the user ID (first authentication information) registered on the IC card is read and transmitted to the parking control device 40. When the user ID is entered (SA3), the parking control device 40 performs first user authentication (first authentication) to determine whether the person attempting to enter the parking lot is a pre-registered user (SA4). Specifically, the parking control device 40 accesses the comprehensive database 52 and determines whether the entered user ID is registered. If the first user authentication fails as a result (SA5:NO), the user is notified of the authentication failure by displaying a message on the touch panel 45 indicating that user authentication failed, and then the first user authentication screen is displayed (SA2).

[0054] On the other hand, if the first user authentication is successful (SA5:YES), that is, if the user ID is registered in the comprehensive database 52, the system is set to an operation-permitted state where input operations from the touch panel 45 of the control panel 22 are possible (SA6), the user ID for which the first user authentication was successful is stored in the storage unit 41 (SA7), and the storage entry start confirmation screen is displayed on the touch panel 45 of the control panel 22 (SA8).

[0055] When the start button is pressed on the vehicle entry start confirmation screen (SA9), the parking control device 40 enters an operation permission state that allows the operation of the mechanical mechanisms (entry / exit doors 4, turntable 8, lift 14, etc.) (SA10), and retrieves an empty pallet from the vehicle storage rack 17. At this time, a vehicle entry waiting confirmation screen indicating the waiting status may also be displayed on the touch panel 45.

[0056] Next, when an empty pallet arrives at the loading / unloading compartment 7 and the landing detection sensor 34 detects that the lift has landed, the landing detection sensor 34 outputs a landing detection signal (SA11). The parking control device 40 displays a door open screen on the touch panel 45 indicating that the loading / unloading door 4 is opening (SA12), and starts opening the door (SA13 in Figure 8). As the loading / unloading door 4 begins to open, the door fully closed detection sensor 67 outputs a fully closed release signal.

[0057] Next, when the door full-open detection sensor 66 detects that the entrance / exit door 4 is fully open, a door full-open detection signal is output (SA14). The parking control device 40 displays an entrance guidance screen on the touch panel 45 prompting the user to enter the parking lot (SA15), and further locks the operation of the control panel 22 so that it does not accept input from the touch panel 45 (SA16). This makes it possible to prevent a third party from inputting from the touch panel 45 while the user is away from the control panel 22.

[0058] After checking the entry guidance screen, the user boards vehicle 2, moves vehicle 2 into the passenger compartment, stops vehicle 2 on the empty pallet that has been transported into the passenger compartment, and returns to the front of the control panel 22. The parking control device 40 displays a second user authentication screen on the touch panel 45 of the control panel 22, prompting the user to enter authentication information (SA17).

[0059] As a result, when a user or other person touches the IC card to the IC card reader 46 and authentication information (second authentication information) is entered (SA18), the parking control device 40 performs second user authentication (SA19). In the second user authentication (second authentication), it is determined whether the received user ID (second authentication information) is a user ID that has been registered in advance. If the second user authentication is successful (SA19: YES), then a matching process is performed to determine whether the user ID (first authentication information) entered in the first user authentication and the user ID (second authentication information) entered in the second user authentication are the same (SA20). In the matching process, it is determined whether the person who opened the entrance / exit door 4 and the person who closed it are the same. If the matching process is successful (SA20: YES), the process proceeds to step SA21.

[0060] On the other hand, if the second user authentication fails (SA19:NO), or if the matching process fails (SA20:NO), the system returns to step SA17 and displays the second user authentication screen. At this point, the system may also notify the user that authentication or matching failed.

[0061] In step SA21, the parking control device 40 puts the control panel 22 into an operation permission state (SA21). Next, the parking control device 40 displays an unoccupied confirmation screen on the touch panel 45 to allow the user to confirm that the passenger compartment is unoccupied (SA22 in Figure 9). On the unoccupied confirmation screen, for example, an unoccupied confirmation button is displayed, along with guidance prompting the user to confirm that the passenger compartment is unoccupied before operating the unoccupied confirmation button. When the unoccupied confirmation button is pressed on this unoccupied confirmation screen (SA23), the parking control device 40 displays a door closing screen on the touch panel 45 of the control panel 22 to close the entrance / exit door 4 (SA24). On the door closing screen, for example, a door closing button is displayed, along with guidance prompting the user to confirm that the passenger compartment is unoccupied again before operating the door closing button.

[0062] In this closed door screen, when the closed door button is pressed (SA25), the parking control device 40 starts closing the door (SA26). As a result, the fully open door detection sensor 66 outputs a fully open release signal. Then, when the door closing detection sensor 67 detects that the entry / exit door 4 is fully closed (SA27), the door closing detection sensor 67 outputs a door closing signal. Next, the parking control device 40 starts storing the vehicle (SA28). Specifically, it drives the lift 14 to store the vehicle in a designated storage rack. As the lift 14 rises, a ground landing release signal is output from the ground landing detection sensor 34. Then, once the storage of the vehicle 2 is complete (SA29), the user ID (first authentication information) stored in the memory unit 41 is erased (SA30), and the parking process is terminated.

[0063] [Power supply control process] Next, an example of the power supply control process performed by the power supply control system 80 when a vehicle is brought into storage will be explained with reference to the figure. Figure 10 is a flowchart showing an example of the processing procedure for the power supply control method performed by the power supply control system 80.

[0064] First, the power supply control unit 82 closes the switch 81 (SB1). This electrically connects the power supply 70 to the door drive unit 63 and the transport equipment drive unit 60, and power is supplied. Next, the power supply control unit 82 determines whether the entry / exit door 4 is in a fully closed state. Specifically, it determines whether a fully closed release signal (off signal) is input from the door fully closed detection sensor 67 (SB2). If the fully closed release signal is not input (SB2: NO), this determination process is repeated. On the other hand, if a fully closed release signal is input (SB2:YES), it is determined whether or not an implantation release signal (off signal) has been input from the implantation detection sensor 34 (SB3). If, as a result, no implantation release signal has been input (SB3:NO), the process returns to step SB2. On the other hand, if a landing release signal is input (SB3: YES), the power supply control unit 82 opens the switch 81 (SB4) and terminates this process. This cuts off the power supply from the power supply 70 to the door drive unit 63 and the transport equipment drive unit 60.

[0065] If the switch 81 is opened, the following recovery operations are performed. For example, the parking control device 40 detects the malfunction and notifies the control panel 22 and the maintenance company of the malfunction. Subsequently, a maintenance worker switches the operation mode of the power supply control system 80 to manual mode. This mode switch is performed, for example, by the maintenance worker operating a mode switching key switch provided on the control panel of the power supply control system 80. After that, the maintenance worker releases the emergency stop button, closes the emergency door 6, and performs an error reset. Once this series of input operations is performed, the power supply control unit 82 of the power supply control system 80 closes the switch 81. Subsequently, through manual operation by the maintenance worker, the transport equipment such as the lift 14 is brought to the ground position and the entrance / exit door 4 is fully closed. After that, when the operation mode of the power supply control system 80 is switched from manual mode to automatic mode by the maintenance worker, the recovery work is completed.

[0066] [Outbound processing] The outbound process is the same as the various processes in the outbound process described above, except that screens specialized for outbound operations, such as the inbound startup confirmation screen (SA8 in Figure 7) and the inbound guidance screen (SA15 in Figure 8), are changed to screens specialized for outbound operations, such as the outbound startup confirmation screen and the outbound guidance screen, and in the pallet retrieval process, an empty pallet is retrieved during inbound operations, while a pallet with a vehicle on it is retrieved during outbound operations. Therefore, a detailed explanation is omitted here.

[0067] Furthermore, the method of power control by the power control system 80 during vehicle departure is the same as during vehicle arrival, so a detailed explanation is omitted here.

[0068] As described above, according to this embodiment, the system includes a switch 81 provided in the circuit connecting the door drive unit 63 and the transport equipment drive unit 60 to the power supply 70, and a power supply control unit 82 that controls the switch 81. The power supply control unit 82 opens the switch 81 and cuts off the power supply to the door drive unit 63 and the transport equipment drive unit 60 when it detects that the entry / exit door 4 is not in a fully closed state and the transport equipment is not in a loaded state. More specifically, the power supply control unit 82 opens the switch 81 when a fully closed release signal is input and a landing release signal is input.

[0069] For example, a state in which a fully closed release signal is input and a grounding release signal is input indicates an abnormal state of the mechanical parking system. Specifically, this means a state in which, during entry and exit, the entry / exit door 4 begins to open before the transport equipment has properly grounded on the entry / exit floor, a state in which the lift 14 begins to move up or down when the entry / exit door 4 is not fully closed, or a state in which the entry / exit door 4 and the transport equipment are operating simultaneously. The entry / exit door 4 must open only when the transport equipment has securely grounded, and the transport equipment must begin to move only when the entry / exit door 4 has securely closed. However, due to various factors such as malfunction of the door control program of the parking control device 40, malfunction of the transport control program, deterioration of the brake circuit of the entry / exit door 4, or deterioration of the brake circuit of the transport equipment leading to brake release, there is a risk that the transport equipment and the entry / exit door may operate simultaneously.

[0070] According to this embodiment, such an abnormal condition is quickly detected, and the power supply to the door drive unit 63 and the transport equipment drive unit 60 is shut off. In other words, according to this embodiment, the power supply itself to the door drive unit 63 that drives the entry / exit door 4 and the transport equipment drive unit 60 that drives the transport equipment is shut off, so it is possible to more reliably prevent the entry / exit door 4 and the transport equipment from being driven compared to when the operation of the entry / exit door 4 and the transport equipment is locked by software processing. As a result, it is possible to reliably prevent the entry / exit door 4 and the transport equipment from being driven when the boarding / alighting area is in an unsafe state, and further enhance safety.

[0071] In this embodiment, only one switch 81 was provided, but the number of switches 81 is not limited. For example, the switch 81 may be configured with multiple switches connected in series. This ensures that even if one switch fails, the other switches remain open, thereby reliably interrupting the power supply.

[0072] [Variation 1] In the first embodiment, the power supply control unit 82 may open the switch 81 and cut off the power supply to the door drive unit 63 and the transport equipment drive unit 60 even when the entrance / exit door 4 is fully closed and a person is detected inside the passenger compartment. Specifically, the power supply control unit 82 is configured to receive a human detection signal from the internal detection sensor 30. The power supply control unit 82 then opens the switch 81 when it receives a fully closed detection signal from the door fully closed detection sensor 67 and a human detection signal from the internal detection sensor 30.

[0073] For example, when the entry / exit door 4 is fully closed, the condition in which a person is detected inside the passenger compartment means that a person is remaining inside. Therefore, if such an abnormal condition is detected, safety can be ensured by opening the switch 81.

[0074] [Variation 2] In the first embodiment, the power supply control unit 82 may also open the switch 81 and cut off the power supply to the door drive unit 63 and the transport equipment drive unit 60 if it detects that the emergency door 6 is not in a fully closed state. Figure 11 is a diagram showing the schematic configuration of the power supply control system according to the modified example 2. As shown in Figure 11, the power supply control unit 82a is configured to receive, in addition to the detection signals from the ground landing detection sensor 34 and the door fully closed detection sensor 67 mentioned above, an emergency stop signal from the control panel 22, a door fully closed release signal (off signal) from the emergency door fully closed detection sensor 36, and a human detection signal from the internal detection sensor 30. Here, the emergency stop signal is a signal (off signal) that is output when the emergency stop button 48 on the control panel 22 is operated. The human detection signal is a signal (off signal) that is output when a person is detected by the internal detection sensor 30. The power supply control unit 82a controls the opening and closing of the switch 81 based on these signals.

[0075] Figure 12 is a flowchart showing an example of the processing procedure for the energization control method executed by the energization control unit 82a.

[0076] First, the power supply control unit 82a closes the switch (SC1). This electrically connects the power supply 70 to the door drive unit 63 and the transport equipment drive unit 60, and power is supplied. Next, the power supply control unit 82a determines whether or not an emergency stop signal has been input from the control panel 22 (SC2). That is, it determines whether or not the emergency stop button 48 provided on the control panel 22 has been pressed. If, as a result, an emergency stop signal (off signal) has been input (SC2: YES), the switch 81 is opened (SC7), and this process ends.

[0077] On the other hand, if no emergency stop signal is input (SC2:NO), it is determined whether a door release signal indicating that the emergency door 6 is not fully closed has been input (SC3). If, as a result, the door release signal has been input (SC3:YES), in other words, if it is detected that the emergency door 6 has opened, the switch 81 is opened (SC7), and this process is terminated.

[0078] On the other hand, if no door release signal is input (SC3:NO), it is determined whether or not a landing release signal (off signal) is input from the landing detection sensor 34 (SC4). If, as a result, no landing release signal is input (SC4:NO), the process returns to step SC2 and this determination process is repeated.

[0079] On the other hand, if a landing release signal is input (SC4:YES), it is determined whether or not a fully closed release signal (off signal) is input from the door fully closed detection sensor 67 (SC5). If a fully closed release signal is input as a result (SC5:YES), the switch 81 is opened (SC7) and this process ends.

[0080] On the other hand, if the fully closed release signal is not input (SC5:NO), that is, if the entrance / exit door 4 is in a fully closed state, it is determined whether or not a person detection signal has been input from the internal detection sensor 30 (SC6). In other words, it is determined whether or not a person has been detected inside the passenger compartment. As a result, if no human detection signal is input (in the case of an ON signal input) (SC6:NO), the process returns to step SC2 and this determination process is repeated. On the other hand, if the human detection signal is OFF input (SC6:YES), the switch 81 is opened (SC7) and this process ends.

[0081] Thus, according to Modification 2, when it is detected that a person has entered the passenger compartment 7 through the emergency door 6, the power supply to the door drive unit 63 and the transport equipment drive unit 60 can be shut off. As a result, the entry / exit door 4 and the transport equipment can be reliably prevented from being driven, thereby enhancing safety.

[0082] [Second Embodiment] Next, a power supply control system, power supply control method, power supply control program, and mechanical parking device according to the second embodiment of this disclosure will be described with reference to the drawings. In the following description, components identical to those in the first embodiment described above will be denoted by the same reference numerals and their descriptions will be omitted. The description will mainly focus on the different components.

[0083] Figure 13 shows an example configuration of the power supply control system 80b according to this embodiment. As shown in Figure 13, the power supply control system 80b according to this embodiment further comprises a door switch 91 and a door power supply control unit 92. The door switch 91 is part of the circuit connecting the power supply 70 and the door drive unit 63, and is located downstream of the switch 81. In this embodiment, the door switch 91 is located downstream of the circuit breaker 74, in other words, in the circuit closer to the door drive unit 63, but this is not the only example. For example, the door switch 91 may be located between the switch 81 and the circuit breaker 74.

[0084] The door switch 91 controls the power supply to the door drive unit 63. The door switch 91 is, for example, a mechanical switch that switches between supplying and cutting off power to the door drive unit 63, and examples include a magnetic contactor and a magnetic switch. The opening and closing of the door switch 91 is controlled by the door power supply control unit 92.

[0085] The door power control unit 92 is configured to receive signals from, for example, the landing detection sensor 34, the door fully open detection sensor 66, the door fully closed detection sensor 67, and the parking control device 40. The door power control unit 92 is, for example, an information processing device and includes a CPU, an auxiliary storage device for storing programs executed by the CPU, a main memory that functions as a work area when each program is executed, and a communication interface for sending and receiving information with other devices. The auxiliary storage device of the door power control unit 92 stores a door power control program for controlling the opening and closing of the door switch 91, and the CPU reads the program stored in the auxiliary storage device into the main memory and executes it to realize the various processes described later.

[0086] The above-mentioned door power supply control program may be pre-stored in an auxiliary storage device such as ROM during the manufacturing of the power supply control system 80b, or it may be downloaded and installed from a server that distributes the program after installation. It may also be installed via an external storage device. Thus, there are no particular limitations on the installation method of the various programs.

[0087] The door power supply control unit 92, for example, when it receives a landing detection signal indicating that the transport equipment is in a landing state during entry or exit, closes the door opener 91 and starts supplying power to the door drive unit 63. At this time, it may also determine whether or not a person is detected inside the passenger compartment, and close the door opener 91 only if the transport equipment is in a landing state and no person is detected inside the passenger compartment. For example, the door power supply control unit 92 may determine whether or not the passenger compartment is empty based on the output signal from the internal detection sensor 30.

[0088] Furthermore, when the door power control unit 92 detects that the entry / exit door 4 is fully open, it opens the door switch 91 and cuts off the power supply to the door drive unit 63. Specifically, when the door power control unit 92 receives a fully open detection signal from the door fully open detection sensor 66, it opens the door switch 91 and cuts off the power supply to the door drive unit 63.

[0089] [Door power supply control process] Next, an example of door power control processing performed by the door power control unit 92 when entering the storage area will be described with reference to the figure. Figure 14 is a flowchart showing an example of the processing procedure for the door power control method performed by the door power control unit 92 of the power control system 80b according to this embodiment. Note that the door power control processing is performed when the switch 81 is closed.

[0090] First, when the parking control device 40 initiates the parking process, the door power supply control unit 92 determines whether or not a landing detection signal has been received from the landing detection sensor 34 (SD1). If no landing detection signal has been received (SD1:NO), the unit remains in standby mode until a landing detection signal is received. On the other hand, if a landing detection signal has been received (SD1:YES), the door power supply control unit 92 closes the door opener 91 (SD2). This initiates the supply of power from the power supply 70 to the door drive unit 63.

[0091] Next, the door power control unit 92 determines whether or not a full-open detection signal has been input from the door full-open detection sensor 66 (SD3). If no full-open detection signal has been input (SD3: NO), the unit remains in standby mode until a full-open detection signal is input. On the other hand, if a full-open detection signal has been input (SD3: YES), the door power control unit 92 opens the door switch 91 (SD4). This cuts off the power supply from the power supply 70 to the door drive unit 63.

[0092] Next, the door power control unit 92 determines whether or not a door closing instruction signal has been input from the parking control device 40 (SD5). This door closing instruction signal is, for example, the signal output from the parking control device 40 to the door drive unit 63 and the door power control unit 92 when a door closing instruction signal is input by a user in step SA25 of Figure 9. If the door power control unit 92 has not received a door closing instruction signal (SD5: NO), it remains in standby mode until a door closing instruction signal is input. On the other hand, if a door closing instruction signal is input (SD5: YES), the door power control unit 92 closes the door switch 91 (SD6). This starts the power supply from the power supply 70 to the door drive unit 63.

[0093] Next, the door power supply control unit 92 determines whether or not a fully closed detection signal has been input from the door fully closed detection sensor 67 (SD7). If no fully closed detection signal has been input (SD7: NO), the unit remains in standby mode until a fully closed detection signal is input. On the other hand, if a fully closed detection signal has been input (SD7: YES), the door power supply control unit 92 opens the door switch 91 (SD8) and terminates this process. As a result, the power supply from the power supply 70 to the door drive unit 63 is cut off.

[0094] According to the above door power supply control method, for example, when the landing of the lift 14 is detected in step SA11 of Figure 7, power supply to the door drive unit 63 is started, and when the full opening of the entry / exit door 4 is detected in step SA14 of Figure 8, power supply to the door drive unit 63 is cut off. Then, when a door closing instruction signal is received by the user in step SA25 of Figure 9, power supply to the door drive unit 63 is started, and when the full closing of the entry / exit door 4 is detected in step SA27 of Figure 9, power supply to the door drive unit 63 is cut off.

[0095] This ensures that power is supplied to the door drive unit 63 only during the period when the entry / exit door 4 needs to be driven, thus preventing malfunctions of the entry / exit door 4 due to program errors or other issues during other periods.

[0096] [Third Embodiment] Next, a power supply control system, power supply control method, power supply control program, and mechanical parking device according to the third embodiment of this disclosure will be described with reference to the drawings. In the first and second embodiments described above, an elevator-type mechanical parking device 1 in which a pallet 18 is transported between the passenger compartment 7 and the vehicle storage rack 17 by a lift 14 was described as an example, but in this embodiment, a planar reciprocating type mechanical parking device 100 in which vehicles are transferred by a conveyor (transportation equipment) will be described as an example.

[0097] Figure 15 is a perspective view showing the schematic structure of the mechanical parking system 100 according to this embodiment. As shown in Figure 15, the mechanical parking system 100 includes, for example, a plurality of double-row storage rack groups 110. The double-row storage rack group 110 consists of a plurality of storage racks 112 arranged in a continuous manner for storing vehicles 2. Each storage rack 112 is equipped with a lateral conveyor 117. One or more trolleys 105 are provided in the passages (trolley tracks) between each double-row storage rack group 110. The trolleys 105 can travel along the double-row storage rack group 110 by, for example, running on rails. The double-row storage rack group 110 has a hierarchical structure, and accordingly, trolleys 105 are provided on each floor. Each trolley 105 is equipped with a lateral conveyor 116 for laterally moving the vehicle 2.

[0098] The double-row storage rack group 110 has a loading / unloading berth 102 on the loading / unloading floor for loading and unloading. The loading / unloading berth 102 is adjacent to the lift lifting room 101 from which the lift (transport equipment) 103 moves up and down. A lateral conveyor 114 (see Figure 16) is installed in the loading / unloading berth 102. In addition, a lateral conveyor 115 is installed in the lift 103. Figure 16 is a schematic external view of the berth (boarding / alighting area) 102. As shown in Figure 16, a partition door 104, for example, is provided between the berth 102, which also serves as a boarding / alighting area, and the lifting / alighting area 101, as an entrance / exit door.

[0099] It should be noted that the configuration of the planar reciprocating mechanical parking device 100 according to this embodiment is just one example, and other known configurations can be adopted.

[0100] Furthermore, the power supply control systems 80, 80a, and 80b described above can also be applied to the planar reciprocating mechanical parking device 100 illustrated in Figures 15 and 16. This enhances safety by cutting off the electrical connection between the power supply and the transport equipment drive unit and the door drive unit, thereby cutting off the power supply to them, when the lift 103 has not reliably landed on the access floor and the compartment door (in / out door) 104 is not fully closed. In a planar reciprocating system, examples of conveying equipment drive units include a lift drive unit that drives the lift 103, a conveyor drive unit that drives various conveyors, and a trolley drive unit that drives the trolley. In addition, an example of a door drive unit is a partition door drive unit that opens and closes the partition door 104.

[0101] Although the present disclosure has been described above using the embodiments described above, the technical scope of this disclosure is not limited to the scope described in the embodiments above. Various modifications or improvements can be made to the embodiments above without departing from the gist of the disclosure, and such modified or improved forms are also included in the technical scope of this disclosure. Furthermore, the flows of receiving processing, shipping processing, power supply control processing, door power supply control processing, etc., described in the embodiments above are just examples, and it is possible to delete unnecessary steps, add new steps, or change the processing order without departing from the spirit of this disclosure.

[0102] For example, the explanation used upward-opening doors as an example for the entry / exit door 4 and the compartment door 104, but it is not limited to these. For example, the entry / exit door 4 and the compartment door 104 may open horizontally or downward (a type that is stored in the ground).

[0103] Furthermore, while cage landing detection devices and the like have been given as examples of landing detection sensors 34, the system is not limited to these. For example, the landing detection sensor 34 can be any sensor or device that can detect when the transport equipment has landed safely in the boarding / alighting room (entry floor). For example, the following devices may be used as the landing detection sensor 34.

[0104] For example, a carrier such as a lift 14 is equipped with a locking mechanism to prevent the equipment from moving due to load fluctuations on the wire rope when it stops at the access floor or storage floor. Such a locking mechanism may also be used as a landing detection sensor 34. In this case, the landing state is defined as when the locking mechanism is activated and locked, and the landing release state is defined as when the lock is released.

[0105] Alternatively, a combination of multiple detection signals, such as the turntable position signal from the turntable position sensor 71 that detects the rotational position of the turntable 8, the position signal from the position sensor that detects the vertical position of the turntable 8, and the detection signal from the pallet sensor that determines whether or not the pallet is in the landing position, may be used to determine that the pallet is in a landing state when these sensor signals meet predetermined conditions.

[0106] For example, the system may determine that the turntable is in a landing state if the rotational position of the turntable detected by the turntable position sensor 71 is in an appropriate position for receiving or shipping goods, and a pallet is detected by the pallet sensor. The operating state of the locking mechanism described above may also be added to these determinations.

[0107] Thus, determining whether or not implantation has occurred can be done based on signals from one or more sensors, and the conditions under which implantation is determined can be set as appropriate according to the operational requirements.

[0108] The energization control system, energization control method, energization control program, and mechanical parking device described in each embodiment above can be understood, for example, as follows.

[0109] The first aspect of the present disclosure of the power supply control system (80, 80a, 80b) is a power supply control system applied to a mechanical parking device (1,100) comprising an entry / exit compartment (7, 102) for entering and exiting vehicles, an entry / exit door (4, 104) provided in the entry / exit compartment, a door driving means (63) for driving the entry / exit door, a transport device (8, 14, 103) which is equipment for transporting vehicles, and a transport device driving means (60) for driving the transport device, wherein the power supply control system comprises a switch (81) provided in an electrical circuit connecting the door driving means and the transport device driving means to a power supply (70), and power supply control means (82, 82a) for controlling the switch, wherein the power supply control means opens the switch and cuts off the power supply to the door driving means and the transport device driving means when it is detected that the entry / exit door is not in a fully closed state and the transport device is not in a grounded state.

[0110] According to the above embodiment, when the entrance / exit doors are not fully closed and the transport equipment is not in a grounded state, the power supply to the door driving means and the transport equipment driving means is cut off. This makes it possible to reliably prevent the entrance / exit doors and transport equipment from operating in an unsafe state of the mechanical parking system. This prevents people from being caught in the operation of the equipment. Furthermore, by cutting off the power itself, it is possible to enhance safety compared to locking the operation of the entrance / exit doors and transport equipment through software processing.

[0111] In the first embodiment of the transport power supply control device according to a second aspect of the present disclosure, the power supply control means (82, 82a) opens the switch to cut off the power supply to the door driving means and the transport equipment driving means when the entrance / exit door is fully closed and a person is detected inside the passenger compartment.

[0112] According to the above embodiment, when the entry / exit door is fully closed and a person is detected inside the passenger compartment, the power supply to the door drive means and the transport equipment drive means is cut off. This makes it possible to reliably prevent the entry / exit door and transport equipment from being driven when a person remains inside the passenger compartment. This makes it possible to increase safety compared to locking the operation of the entry / exit door and transport equipment by software processing.

[0113] A third aspect of the present disclosure provides a power supply control system, in the first or second aspect described above, comprising an electrical circuit connecting the power supply and the door driving means, a door switch (91) provided downstream of the switch (81), and a door power supply control means (92) for controlling the door switch, wherein the door power supply control means opens the door switch to cut off the power supply to the door driving means when the loading / unloading door is fully closed, closes the door switch to enable power supply to the door driving means when it is detected that the transport equipment has landed, and opens the door switch to cut off the power supply to the door driving means when the loading / unloading door is fully open.

[0114] According to the above embodiment, the power supply to the door driving means can be cut off during periods when it is not necessary to drive the entry / exit door. This prevents the entry / exit door from being driven due to software malfunction or other reasons, thereby enhancing safety.

[0115] A mechanical parking system according to a fourth aspect of the present disclosure comprises an entry / exit compartment for entering and exiting vehicles, an entry / exit door provided in the entry / exit compartment, a door driving means for driving the entry / exit door, a transport device which is equipment for transporting vehicles, a transport device driving means for driving the transport device, and an electrical control system according to any of the first to third aspects described above.

[0116] According to the above embodiment, it is possible to reliably prevent the entry / exit doors and transport equipment from operating in an unsafe state of the mechanical parking system. This makes it possible to enhance safety compared to locking the operation of the entry / exit doors and transport equipment by software processing.

[0117] A mechanical parking system according to a fifth aspect of the present disclosure includes, in the fourth aspect described above, a parking control device (40) for controlling the mechanical parking system, wherein the power supply control means is provided separately from the parking control device and operates independently of the parking control device.

[0118] According to the above embodiment, even if the parking control device malfunctions, the power supply control means can detect the abnormality of the mechanical parking device and promptly cut off the power supply to the drive means. This makes it possible to improve safety.
