Description

[Technical Field]

[0001] The present invention relates to a two-level parking system installed outdoors. [Background technology]

[0002] Mechanical parking systems are installed inside buildings constructed above ground or in underground spaces to store a large number of vehicles in a multi-level manner. Various types of mechanical parking systems are used, including elevator systems, comb elevator systems, vertical circulation systems, multi-level circulation systems, horizontal circulation systems, flat shuttle systems, and two-tier systems. With these mechanical parking systems, contracted vehicles tend to leave the parking lot in a concentrated manner during certain times of the day (e.g., during the day), which can result in empty spaces.There has been a demand for a way to effectively utilize these empty pallets during times when they are not in use.

[0003] For example, Patent Document 1 discloses the use of pallets in a mechanical parking device as a takeoff and landing site for unmanned aerial vehicles (such as drones) carrying luggage and as a storage site for luggage. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2019-214888 Summary of the Invention [Problem to be solved by the invention]

[0005] The mechanical parking device in Patent Document 1 requires only one lift to both park the baggage carrier at the takeoff and landing location and to transport the baggage carrier to the baggage receiving location, so it is not possible to receive baggage from a drone and deliver another baggage at the same time.

[0006] The present invention has been devised to solve the above-mentioned problems. That is, an object of the present invention is to provide a two-level multi-level parking system that can utilize an empty pallet as a place to receive luggage from an unmanned aerial vehicle and can perform the operation of receiving luggage and the operation of handing over another luggage in parallel. [Means for solving the problem]

[0007] According to the present invention, a two-tiered parking device having two or more parking spaces in the same installation space, and having a plurality of such installation spaces, a plurality of pallets for loading the vehicle; a pallet driving device that moves the pallet laterally or vertically between the parking space and the vehicle entry / exit position; a communication device for bidirectional communication with the unmanned aircraft carrying the cargo; a control device that selects one of the pallets that is at the top and is empty among the plurality of pallets in each installation space and designates it as a landing site where the unmanned aerial vehicle can take off and land; A two-level multi-level parking device is provided in which the control device controls the pallet drive device, sends and receives communication via the communication device, or specifies the landing location in parallel. [Effects of the Invention]

[0008] According to the present invention described above, a single space has multiple installation spaces with two or more levels of parking spaces. In other words, the present invention has two or more parking spaces that can be designated as landing locations for unmanned aircraft. The control device selects one of the topmost empty pallets among the multiple pallets in each installation space and designates it as a landing location where the unmanned aircraft can take off and land. In addition, the control device can simultaneously control the pallet drive device, send and receive communications via the communication device, and designate a landing location. Therefore, the present invention allows luggage received at one landing location to be picked up and delivered at another landing location, so that luggage receiving and delivery operations can be carried out in parallel.

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In addition, common parts in the drawings are given the same reference numerals, and duplicated explanations will be omitted.

[0011] (First embodiment) The first embodiment is a front view of a mechanical parking system that is a two-level parking system in which the uppermost pallet only moves up and down. FIG. 1 is a front view of a two-level parking system 100 according to the first embodiment. Two-level multi-level parking devices 100 can be broadly divided into ground-level types in which parking spaces 3 are provided only on the ground, and pit-level types in which parking spaces 3 are provided above ground and underground. In both ground-level and pit-level types, the vehicle 1 is loaded and unloaded by directly loading the vehicle 1 onto a pallet located at the loading / unloading height (FL), or by unloading the vehicle 1 from a pallet at the loading / unloading height. The two-level parking device 100 raises and lowers or moves the pallet 2 sideways into the parking space 3, thereby creating two or more levels of parking spaces 3 in the same installation spaces A, B, C, and parking the vehicle 1. The two-level parking device 100 has multiple adjacent installation spaces A, B, C.

[0012] In the example shown in this figure, the two-level parking device 100 of this embodiment is a ground-level three-level lift-and-transverse type with three levels (1F, 2F, 3F) of vehicle parking spaces 3 provided in the same installation spaces A, B, and C. The two-level parking device 100 in this example has 3 levels x 3 rows = 9 parking spaces 3.

[0013] In this example, of the three tiers, two pallets 2 located on the first floor can move horizontally, two pallets 2 located on the second floor can move horizontally and rise and fall, and three pallets 2 located on the third floor can only rise and fall. Therefore, in this example, the capacity of the vehicle 1 is 3×3−2=7 vehicles.

[0014] In this example, the triple-entered, two-tiered parking device 100 has three loading and unloading positions in installation spaces A, B, and C. The loading and unloading positions are parking spaces 3 on the first floor above ground. The overall width of the pallets 2 is preferably the same, but may be different. Note that each loading and unloading position in installation spaces A, B, and C is arranged so that the three pallets 2 are positioned adjacent to each other with a required gap (for example, 40 mm or less) between them. The two-level parking device 100 is equipped with a pallet drive device 5 that moves the pallet 2 laterally or raises and lowers it between the parking space 3 and the entry / exit position of the vehicle 1. The pallet drive device 5 has a horizontal drive device that moves the pallet 2 laterally, and a lifting drive device 5a that raises and lowers the pallet 2.

[0015] The two pallets 2 located on the first floor have wheels 6a at both ends in the longitudinal direction, and are driven horizontally by a horizontal drive device (not shown) along two horizontal rails 8a provided on the first floor, allowing the vehicle 1 to be directly brought in and out of one of the entry and exit positions in installation spaces A, B, and C. Hereinafter, "entering and retrieving" refers to entering and retrieving.

[0016] The two pallets 2 located on the second floor have wheels 6b at both longitudinal ends of the rectangular frame 7 that hoists them. The rectangular frame 7 surrounds the pallet 2 parked on the intermediate level between the top and bottom levels, and is installed so that it can move sideways while suspending the pallet 2. With this configuration, the two pallets 2 located on the 2nd floor are moved horizontally along horizontal rails 8b installed on the 2nd floor by a horizontal drive device (not shown), allowing the vehicle 1 to be directly loaded and unloaded at one of the loading and unloading positions in installation spaces A, B, and C.

[0017] In this example, the two-tiered parking device 100 has a pallet 2 that can be raised and lowered to carry the vehicle 1 between the entry / exit height (FL) at which the vehicle 1 enters and exits, and a parking space 3 above this entry / exit height. The pallets 2 that can be raised and lowered correspond to the two pallets 2 located on the second floor and the three pallets 2 located on the third floor.

[0018] In this example, the two-level parking system 100 further includes a lifting drive device 5a for lifting and lowering the pallet 2. The lifting drive device 5a winds up or unwinds a flexible string member 4 (chain or wire) that extends vertically at a position that does not interfere with the vehicle 1, and raises or lowers the lower end of the string member.

[0019] The lifting drive device 5a on the second floor is fixed to the rectangular frame 7 and moves horizontally together with the rectangular frame 7. The lifting drive device 5a for the third floor is fixed to the main body frame 9, and is configured to lift and lower the three pallets 2 from the main body frame 9 independently.

[0020] In addition, in this example, the lower ends of the four string members 4 are fixed to a total of four locations, at the front and back of the pallet 2, taking into account the load balance, and the lifting drive device 5a lifts and lowers the pallet 2 while keeping it horizontal.

[0021] The two-level parking device 100 of this embodiment further includes a communication device 10 that communicates bidirectionally with an unmanned aerial vehicle D (e.g., a drone D), and a control device 11 that specifies a landing location where the unmanned aerial vehicle D can take off and land. Hereinafter, this embodiment will be described using the drone D as an example of the unmanned aerial vehicle D.

[0022] The control device 11 knows the unique numbers and positions of the pallet 2 carrying the vehicle 1 and the empty pallet 2. The control device 11 then designates one of the empty pallets 2 that is at the top of the multiple pallets 2 in each of the multiple installation spaces A, B, and C as a landing site where the drone D can take off and land. One empty pallet 2 can carry one piece of cargo L. The control device 11 can also control the operation of the pallet driving device 5, send and receive communications via the communication device 10, and designate a landing site, all in parallel. The control device 11 also controls the operation of the pallet driving device 5 to move the pallet 2.

[0023] The communication device 10 communicates bidirectionally with the drone D to exchange information about the baggage L carried by the drone D. The information includes, for example, user information, baggage code, various request notifications, permission notifications, etc. The communication device 10 outputs the contents of this communication to the control device 11.

[0024] 2 is a plan view of the two-level parking device 100 of the first embodiment. The two-level parking device 100 has multiple installation spaces A, B, and C, and each of the same installation spaces A, B, and C has two or more levels of parking spaces 3. Therefore, when the two-level parking device 100 is viewed from above, the three pallets 2 in the topmost parking spaces 3 of the installation spaces A, B, and C appear to be open upward. The two-level parking device 100 uses the empty pallets 2 in these topmost parking spaces 3 as a landing site for drone D.

[0025] As shown in the figure, a two-dimensional code 12 that specifies the landing position of drone D is displayed on pallet 2, and control device 11 may specify the landing location by transmitting the two-dimensional code information of pallet 2 to be landed from communication device 10 to drone D. In this case, pallet 2 itself, rather than parking space 3, is specified as the landing location.

[0026] In the example shown in this figure, the two-dimensional code 12 is provided in the center of a foldable pallet 2. This prevents the tires of the vehicle 1 from running over the two-dimensional code 12, allowing the two-dimensional code 12 to be maintained for a long period of time without being damaged.

[0027] The two-dimensional code 12 may be displayed on a display 12a, and may be switchable between display and non-display. This reduces the possibility that the drone D will land on the wrong pallet 2 by displaying the two-dimensional code 12 only on the display 12a of the pallet 2 at the landing location specified by the control device 11 among multiple landing locations.

[0028] However, the method by which the control device 11 specifies the landing location is not limited to this. For example, the landing location may be specified by transmitting relative position data (RTK), position coordinates by the Quasi-Zone Satellite System (QZSS), or GPS to the drone D. In this case, the parking space 3, not the pallet 2, is specified as the landing location.

[0029] With this configuration, the two-level parking device 100 of this embodiment can effectively utilize empty pallets 2 as a receiving area for luggage L delivered by drones D. Furthermore, with this configuration, simply by adding a communication device 10 and a control device 11 to an existing two-level parking device, it is possible to easily add to the two-level parking device 100 a function for receiving luggage L from delivery drones D without the need for major construction work. Furthermore, the two-level parking device 100 can be converted into a receiving area for luggage L without the need to provide a dedicated luggage receiving space for drones D. Furthermore, by moving the pallet 2 carrying the luggage L to the loading / unloading position in the same way as when the vehicle 1 is loaded or unloaded, the luggage L can be easily handed over to the recipient of the luggage L.

[0030] When the control device 11 receives a contractor's cargo L during an exit operation, it is preferable to move the pallet 2 carrying the cargo L to the entry / exit position as the pallet 2 to be loaded, even if the contractor normally parks on a different pallet 2. For example, suppose that the contractor's data for the two-level parking device 100 registers a pallet 2 on the first ground floor as the contractor's registered pallet, but the pallet 2 that received the cargo L during the contractor's exit is the empty pallet 2 on the top level. In this case, the control device 11 rewrites the contractor's registered pallet stored in the contractor data from the pallet 2 on the first ground floor to the topmost pallet 2 that received the cargo L. As a result, when the contractor performs a loading operation, the pallet 2 carrying the contractor's cargo L is automatically called, and the contractor can retrieve the cargo L and load it onto that pallet 2. This allows the user to retrieve the cargo L at the same time as calling up the pallet 2 for storage, eliminating the need to call up the pallet 2 twice. This contributes to user convenience and also shortens the time required for storage and receipt of the cargo L.

[0031] Next, the operation of the two-level parking system 100 of the first embodiment will be described. 3 and 4 are explanatory diagrams of the operation of the two-level parking system 100 of the first embodiment. (Step 1) When the drone D carrying the luggage L approaches the delivery destination, it transmits a landing request signal to the target two-level multi-level parking device 100. At this time, it is preferable that the drone D transmits the luggage code of the luggage L to the two-level multi-level parking device 100.

[0032] (Step 2) Next, upon receiving the landing request signal, the two-level parking device 100 prepares a state in which the drone D can land. Specifically, the control device 11 selects an empty pallet 2 for the drone D to land on. At this time, it is more preferable that there are empty pallets 2 on the left and right of the pallet 2 that will be the landing location. This reduces the possibility of the parked vehicle 1 being damaged by contact with the drone D.

[0033] The control device 11 derives the recipient by comparing the contracted user data as a parking lot user of the two-level parking device 100 with the recipient information obtained from the parcel code, and if the contracted pallet 2 of the recipient contracted user is vacant and can be selected as a landing location, the control device 11 may designate that pallet 2 as the landing location. If the contracted pallet 2 is not vacant, the control device 11 designates a common pallet 2 that can receive anyone's parcel L as the landing location. Also, if the recipient of the parcel L is someone who is not a contracted user of the parking device, the control device 11 designates the common pallet 2 as the landing location.

[0034] (Step 3) When preparations for landing are complete in step 2, the two-level parking device 100 transmits a notification of completion of preparation to the drone D. At this time, the two-level parking device 100 confirms that there are no people or vehicles 1 around the two-level parking device 100 using LiDER (a device that uses a laser to identify the shape of an object and measure the distance), sensors, and surveillance cameras installed on the two-level parking device 100 for safety confirmation when entering and leaving the parking lot, before transmitting the notification of completion of preparation. The preparation completion notification includes information indicating the landing site designated to the control device 11.

[0035] The landing site may be designated by displaying a two-dimensional code 12 on the pallet 2 as shown in FIG. Alternatively, the control device 11 may specify a landing location by transmitting relative position data (RTK) or position coordinates obtained by the Quasi-Zone and Satellite System (QZSS) or GPS to the drone D. In this case, for example, a position information transmitter may be provided in the two-level parking device 100, and the position correction information transmitted by the position information transmitter may be transmitted to the drone D via the communication device 10. Alternatively, a position information transmitter may be installed on each pallet 2, and landing position information may be transmitted directly from the position information transmitter of the pallet 2 that is to be the landing location.

[0036] When the landing location of the drone D is specified by transmitting relative position data or position coordinates, it is not necessary to display the two-dimensional code 12 on the pallet 2. This makes it possible to easily convert an existing two-level multi-level parking device into a two-level multi-level parking device 100 having a landing location for the drone D without having to draw the two-dimensional code 12 on the pallet 2 or install a display 12a.

[0037] (Step 4) Next, drone D lands at the designated landing location and places cargo L there. (Step 5) Thereafter, drone D sends a takeoff request signal to the two-level parking device 100.

[0038] (Step 6) When the two-level parking device 100 receives the takeoff request signal, it checks the surroundings and usage status and gives permission for takeoff to the drone D. Specifically, similar to step 3, the two-level parking device 100, such as a LiDAR, uses sensors and surveillance cameras installed to check safety when entering and leaving the parking lot to confirm that there are no people or vehicles 1 in the vicinity. The two-level parking device 100 may also measure the surrounding wind speed using an anemometer provided for takeoff and landing of the drone D, and issue takeoff permission to the drone D. Note that if the user has made a reservation for operation, the control device 11 will not issue takeoff permission.

[0039] In addition, when the drone D takes off or lands, it is preferable that the control device 11 alerts people around the two-level parking device 100 by providing audio guidance from a speaker or turning on an indicator light, etc.

[0040] The control device 11 also stores the unique number of the pallet 2 that has become the landing location and the baggage code of the baggage L in association with each other.

[0041] (Step 7) When drone D receives takeoff permission from the two-level parking device 100, it takes off as shown in Figure 3(B) and moves away from the two-level parking device 100. (Step 8) Next, when drone D moves a certain distance away from the two-level parking device 100, it sends a takeoff completion notification to the two-level parking device 100.

[0042] (Step 9) When the control device 11 of the two-level parking device 100 receives the takeoff completion notification from the drone D, it transmits a notification (hereinafter, a package arrival notification) informing the user that the package L has arrived. The control device 11 may, for example, notify the manager of ancillary facilities of the two-level parking device 100 (for example, an apartment building that owns the two-level parking device 100) of the package arrival notification. Alternatively, if the two-level parking device 100 is attached to an apartment building or other collective housing complex, the control device 11 may derive the recipient information of the package L from the package code by comparing the contractor data of the two-level parking device 100 or the resident information of the ancillary facilities, and then notify the recipient information of the package L via a management terminal of the ancillary facilities of the apartment building or a parking device management system.

[0043] (Step 10) Upon receiving the notification of the arrival of the luggage, the user performs the luggage collection operation at the two-level multi-level parking device 100. The procedure for the luggage collection operation and the subsequent movement of the pallet 2 are the same as when the vehicle 1 enters or leaves the parking lot. For example, the user may operate a control panel attached to the two-level multi-level parking device 100 to move the pallet 2 carrying the desired luggage L to the entry / exit position. For example, in Figure 3, cargo L is placed on pallet 2 on the third floor above ground in installation space A. The control device 11 operates the horizontal drive device to move pallets 2 on the second and first floors above ground in installation space A laterally, clearing parking space 3 in installation space A below the third floor above ground. Next, the lift drive device 5a is driven to lower the target pallet 2 from the third floor above ground to the first floor above ground. After the target pallet 2 arrives at the loading / unloading position, an entrance door (not shown) at the loading / unloading position opens, inviting the user into the loading / unloading position. This allows the user to enter the loading / unloading position and pick up the cargo L.

[0044] The control device 11 can control the pallet drive device 5, send and receive communications via the communication device 10, or designate a landing location in parallel. Therefore, if the control device 11 subsequently receives a landing request signal from the next drone D, it may proceed with the landing operation of the next drone D even before the pallet 2 has returned to its original parking space 3 after the recipient has received the package L. Specifically, in parallel with returning the pallet 2 on the ground 3F of the installation space A to its original position, the control device 11 may designate one of the remaining two pallets 2 on the ground 3F as a landing location (steps 1 and 2), send a preparation completion notification to the drone D (step 3), and cause the drone D to land and take off (steps 4 to 8), thereby receiving the package L.

[0045] In this way, the two-level parking device 100 of this embodiment has multiple pallets 2 that can be used as landing locations, and the control device 11 can start the operation of receiving the next piece of luggage L before the delivery of the previously received piece of luggage L is completed, as shown in FIG. 4. This allows the two-level parking device 100 of this embodiment to proceed with the operation of receiving one piece of luggage L and the operation of delivering another piece of luggage L in parallel. In other words, it is possible to receive pieces of luggage L from the drones D one after another while minimizing the downtime of the pallet driving device 5. This makes it possible to shorten the time required for the operation of receiving the piece of luggage L from the drones D. It also makes it possible to shorten the waiting time for users entering and leaving the parking lot and for users receiving the piece of luggage L.

[0046] (Second embodiment) FIG. 5 is a front view of the two-level parking system 100 of the second embodiment. The two-level parking system 100 of the second embodiment differs from the first embodiment in that all pallets 2 are capable of both lateral movement and elevation. The two-level parking system 100 of this figure has two pallets 2 on the top level (third floor in the example of this figure), and these two pallets 2 are capable of both lateral movement and elevation. In other words, all pallets 2 on the second floor and above in this embodiment are capable of both lateral movement and elevation. Therefore, in this example, the capacity of the vehicle 1 is 3×3−3=6.

[0047] It is preferable that the control device 11 specify the landing location using the two-dimensional code 12. This is because the pallet 2 serving as the landing location can be seen from above no matter what step height the pallet 2 is at, and so the drone D can land by aiming at the two-dimensional code 12. However, the method of specifying the landing site is not limited to this. The landing site may also be specified using position coordinates obtained from QZSS or GPS, which can identify the vertical position coordinates. In this case, vertical position information of the landing site is required.

[0048] In this way, in the two-level parking device 100 of the second embodiment, all pallets 2 are capable of traversing, so that the drone D can land on pallets 2 other than the top level. This allows the drone D to take off and land on a pallet 2 below the top level, and the luggage L can be stored on a level below the top level to prevent the luggage L from getting wet in the rain. In addition, when the two-level parking device 100 of this embodiment is a pit type, the luggage L may be stored on an underground pallet 2. When the luggage L is stored underground, the pallet 2 in the pit that has risen to the first floor above ground becomes the landing place for the drone D. Other configurations of this embodiment are the same as those of the first embodiment.

[0049] 6 and 7 are explanatory diagrams of the operation of the two-level parking system 100 of the second embodiment. First, we will explain the case where the pallet 2 circled in Figure 6(A) is used as the landing site for drone D. As mentioned above, in the event of rain, it is preferable for the control device 11 to designate a pallet 2 below the topmost pallet as the landing site so that the cargo L does not get wet. The control device 11 moves the designated pallet 2 to the top of the pallets 2 arranged in the same installation space A, B, or C, and then designates it as the landing site.

[0050] First, the operation in step 1 is the same as in the first embodiment. (Step 2) Upon receiving the landing request signal from drone D, the two-level multi-level parking device 100 prepares a state in which drone D can land. Drone D can use the empty pallet 2 that is exposed at the top as a landing site. In other words, even if the pallet 2 is on the first or second floor above ground in this figure, drone D can land if the pallet 2 is moved laterally so that the top surface of the pallet 2 is exposed above the two-level parking device 100. In the example of this figure, by moving the upper pallet 2 of the pallet 2 designated as the landing site laterally, the top surface of the pallet 2 is opened (exposed) above the two-level parking device 100 as shown in FIG. 6(B). This allows drone D to descend along installation space B and land on the pallet 2 on the second floor above ground as shown in FIG. 6(C).

[0051] Of course, the method of moving the target pallet 2 to expose it to the sky above the two-level parking device 100 is not limited to this. In the case of this figure, the target pallet 2 may be moved laterally to the installation space C, thereby exposing the top surface of the pallet 2 to the sky. Other operations in step 2 are the same as those in the first embodiment.

[0052] The subsequent operations in steps 3 to 10 are the same as those in the first embodiment. In this way, because all of the pallets 2 are capable of moving laterally, the two-level parking device 100 of the second embodiment can use the empty pallets 2 in all of the parking spaces 3 as landing sites for the drones D. Therefore, it is possible to store as many pieces of luggage L as there are empty pallets 2. Furthermore, when it rains, the control device 11 selects a pallet 2 below the topmost level as a landing site, and while the luggage L is being stored, the control device 11 moves the pallet 2 above it on top of the pallet 2 carrying the luggage L, thereby protecting the luggage L from the rain.

[0053] Furthermore, once the marker (2D code 12) at the landing location of drone D is installed, it is generally difficult to change. Conventionally, unless the marker itself can be moved, the landing location of drone D could not be changed. However, in the two-level parking device 100 of this embodiment, the pallet 2 with the two-dimensional code 12 attached can be moved, and by moving the pallet 2 itself, it is possible to respond to changes in the landing location of the drone D according to the situation. Therefore, the two-level parking device 100 of this embodiment uses the movement function of the pallet 2 that existing two-level parking devices normally have, and by specifying the top of that pallet as the landing location for the drone D, it is possible to realize a drone port that can respond to changes in the landing location for the drone D. The other configurations, operation methods, and effects of this embodiment are the same as those of the first embodiment.

[0054] The two-level parking system 100 of the second embodiment is not limited to the configuration described above. For example, the two-level parking system 100 of the second embodiment may be a puzzle-type two-level parking system in which all pallets can move up and down and sideways, as disclosed in Japanese Patent Application Laid-Open No. 2020-2569. In this case, the control device 11 moves the pallet 2 designated as the landing location to a parking space 3 where the unmanned aircraft can land (for example, the parking space 3 on the top level or the parking space 3 directly below an empty parking space 3), and allows the drone D to take off and land. After that, it is preferable to place the pallet 2 carrying the cargo L on a level below the top level.

[0055] According to the present invention described above, there are multiple installation spaces A, B, and C, each with two or more levels of parking spaces 3, in the same space. In other words, the present invention has two or more parking spaces 3 that can be designated as landing locations for unmanned aerial vehicle D. The control device 11 selects one of the topmost and empty pallets 2 among the multiple pallets 2 in each installation space A, B, and C, and designates it as a landing location from which unmanned aerial vehicle D can take off and land. In addition, the control device 11 can simultaneously control the pallet drive device 5, send and receive communications via the communication device 10, and designate a landing location. Therefore, the present invention allows the operation of receiving and handing over luggage L received at one landing location to receive other luggage L at another landing location, so that the operation of receiving and handing over luggage L can be performed in parallel.
