Description

[Technical field]

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

[0002] A mechanical parking system is a facility that stores a large number of cars in a multi-level manner by installing a mechanical device inside a building constructed above ground or in a space formed underground. There are various types of mechanical parking systems in use, such as the elevator system, comb elevator system, vertical circulation system, multi-level circulation system, horizontal circulation system, flat shuttle system, and two-tier system. In these mechanical parking devices, contracted vehicles tend to leave the parking lot at certain times (e.g., during the day), which can result in empty spaces. There has been a demand for a way to effectively utilize such empty pallets during times when they are not in use.

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

[0004] [Patent Document 1] JP 2019-214888 A 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 site and transport it to the baggage collection site, so it is not possible to receive baggage from a drone and hand over another baggage in parallel.

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

[0007] According to the present invention, a two-level parking device having two or more parking spaces in the same installation space, A plurality of pallets for carrying vehicles; A pallet driving device that moves the pallet laterally or vertically between the parking space and the vehicle entry / exit position; A communication device that communicates bidirectionally with the unmanned aircraft that transports luggage; A control device that selects one of the pallets that is at the top and 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, transmits and receives communication via the communication device, or specifies the landing location in parallel. Effect of the Invention

[0008] According to the present invention described above, there are multiple installation spaces each having two or more levels of parking spaces in the same space. 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 pallets that is the topmost and empty 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 control the pallet drive device, send and receive communications via the communication device, or designate a landing location in parallel. Therefore, the present invention allows baggage received at one landing location to be picked up and delivered at another landing location, thereby enabling baggage receiving and delivery operations to be carried out in parallel.

[Figure 7] 11 is an explanatory diagram of the operation of the two-level parking system of the second embodiment. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In addition, common parts in each drawing 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 top pallet only moves up and down. FIG. 1 is a front view of a two-level parking device 100 according to the first embodiment. The two-level parking device 100 can be broadly divided into a ground type in which the parking spaces 3 are provided only on the ground, and a pit type in which the parking spaces 3 are provided above ground and underground. In both the ground type and the pit type, 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 the pallet at the loading / unloading height. The two-level parking device 100 raises and lowers or moves the pallet 2 laterally into the parking space 3, thereby providing 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-traverse 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 of 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 vehicle 1 is 3×3−2=7 vehicles.

[0014] In this example, the triple-articulated two-level multi-level parking device 100 has three entry and exit positions in installation spaces A, B, and C. The entry and exit positions are parking spaces 3 on the ground floor. The overall width of the pallets 2 is preferably the same, but may be different. Note that each entry and exit position in installation spaces A, B, and C is arranged so that the three pallets 2 are adjacent to each other with a required gap (e.g., 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 entrance / 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 1st floor have wheels 6a at both ends in the length direction, and are moved horizontally by a horizontal drive device (not shown) along two horizontal rails 8a installed on the 1st floor, allowing the vehicle 1 to enter and leave the warehouse directly at any of the entry and exit positions of the installation spaces A, B, and C. Hereinafter, entry and exit refers to entering and leaving the warehouse.

[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 laterally while suspending the pallet 2. With this configuration, the two pallets 2 located on the 2nd floor are moved horizontally along a horizontal rail 8b installed on the 2nd floor by a horizontal drive device (not shown), allowing the vehicle 1 to be directly loaded and unloaded from any of the loading and unloading positions in the installation spaces A, B, and C.

[0017] In this example, the two-level parking device 100 has a pallet 2 that can raise and lower the vehicle 1 between a parking entry / exit height (FL) at which the vehicle 1 enters and exits, and a parking space 3 above this parking 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 described above.

[0018] In this example, the two-level parking device 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 lifts 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 and lowering 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 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 consideration 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 site 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 topmost and empty pallets 2 among 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 luggage 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 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 these communications 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 a plurality of installation spaces A, B, and C, and each of the same installation spaces A, B, and C is provided with 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 uppermost parking space 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 the uppermost parking space 3 as a landing site for the drone D.

[0025] As shown in the figure, a two-dimensional code 12 that specifies the landing position of the drone D is displayed on the pallet 2, and the control device 11 may specify the landing location by transmitting the two-dimensional code information of the pallet 2 to be landed from the communication device 10 to the drone D. In this case, the pallet 2 itself, rather than the 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 by a display 12a, and the display may be switched between on and off. This reduces the possibility of drone D landing on the wrong pallet 2 by displaying the two-dimensional code 12 only on the display 12a of the pallet 2 at the landing site specified by the control device 11 among multiple landing sites.

[0028] However, the method of the control device 11 specifying the landing site is not limited to this. For example, the landing site may be specified by transmitting relative position data (RTK), position coordinates by the Quasi-Zopher 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 site.

[0029] With this configuration, the two-level parking device 100 of this embodiment can effectively utilize the empty pallet 2 as a receiving location for luggage L delivered by the drone D. Furthermore, with this configuration, by simply adding the communication device 10 and the control device 11 to an existing two-level parking device, the two-level parking device 100 can easily be given a function for receiving luggage L from a delivery drone D without the need for major construction work. Furthermore, the two-level parking device 100 can be modified into a receiving location for luggage L without the need to provide a luggage receiving space dedicated to the drone D. Furthermore, by moving the pallet 2 carrying the luggage L to the loading / unloading position in the same manner as when the vehicle 1 enters or leaves the warehouse, the luggage L can be easily handed over to the recipient of the luggage L.

[0030] When the control device 11 receives the baggage L of a contractor who has performed a parking operation while the contractor is departing, it is preferable that the control device 11 moves the pallet 2 carrying the baggage L to the parking / retrieval position as the pallet 2 to be parked, even if the contractor usually parks on a different pallet 2. For example, suppose that the pallet 2 on the ground level 1F is registered as the contractor's registered pallet in the contractor data of the two-level multi-level parking device 100, but the pallet 2 that received the baggage L while the contractor was departing was the topmost empty pallet 2. In this case, the control device 11 rewrites the contractor's registered pallet stored in the contractor data from the pallet 2 on the ground level 1F to the topmost pallet 2 that received the baggage L. As a result, the pallet 2 carrying the contractor's baggage L is automatically called when the contractor performs a parking / retrieval operation, and the contractor can store the baggage L on the pallet 2 as it is while collecting the baggage L. This allows the user to retrieve the luggage 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. Also, the time required for storage and receipt of the luggage L can be shortened.

[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 baggage 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 baggage code of the baggage L to the two-level multi-level parking device 100.

[0032] (Step 2) Next, upon receiving the landing request signal, the two-level multi-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 the left and right sides of the pallet 2 serving as the landing site are empty pallets 2. This can reduce 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 contractor data as a parking lot user of the two-level parking device 100 with the recipient information acquired from the baggage code, and may designate the contracted pallet 2 of the contractor who is the recipient as the landing place if the pallet 2 is vacant and can be selected as a landing place. If the contracted pallet 2 is not vacant, the control device 11 designates the common pallet 2 that can receive anyone's baggage L as the landing place. Also, if the recipient of the baggage L is a person who is not a contractor for the parking lot, the control device 11 designates the common pallet 2 as the landing place.

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

[0035] The landing site may be specified by displaying a two-dimensional code 12 on the pallet 2 as shown in FIG. Alternatively, the control device 11 may specify the landing location by transmitting relative position data (RTK) or position coordinates by the Quasi-zonal 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 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 in 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 drawing the two-dimensional code 12 on the pallet 2 or installing a display 12a.

[0037] (Step 4) Next, drone D lands at the instructed landing site and places cargo L there. (Step 5) Then, 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 a takeoff request signal, it checks the surroundings and usage status and gives permission for the drone D to take off. Specifically, similar to step 3, the two-level parking device 100 such as LiDER 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 with an anemometer provided for takeoff and landing of the drone D, and give takeoff permission to the drone D. Note that if the user has made a reservation for operation, the control device 11 does not give 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 was the landing site 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 multi-level parking device 100, it takes off as shown in Figure 3 (B) and moves away from the two-level multi-level parking device 100. (Step 8) Next, when drone D moves a certain distance away from the two-level multi-level parking device 100, it sends a takeoff completion notification to the two-level multi-level parking device 100.

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

[0043] (Step 10) The user who has received the notification of the arrival of the luggage performs the luggage receiving operation at the two-level multi-level parking device 100. The method of the luggage receiving operation and the subsequent movement of the pallet 2 are the same as when the vehicle 1 enters and leaves the parking lot. For example, the pallet 2 carrying the desired luggage L may be moved to the entrance / exit position by operating an operation panel attached to the two-level multi-level parking device 100. For example, in FIG. 3, a package L is placed on a pallet 2 on the 3rd floor above ground in installation space A. The control device 11 operates the horizontal drive device to move the pallets 2 on the 2nd and 1st floors above ground in installation space A sideways, freeing up the parking space 3 in installation space A below the 3rd floor above ground. Next, the lift drive device 5a is driven to lower the target pallet 2 from the 3rd floor above ground to the 1st floor above ground. After the target pallet 2 arrives at the loading / unloading position, an entrance door (not shown) of the loading / unloading position is opened, and the user is invited into the loading / unloading position. This allows the user to enter the loading / unloading position and pick up the package L.

[0044] The control device 11 can control the pallet driving device 5, send and receive communication 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, the control device 11 may proceed with the landing operation of the next drone D even before the pallet 2 after the recipient receives the package L returns to the original parking space 3. 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 have the drone D land and take off (steps 4 to 8), and receive 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 baggage L before the delivery of the previously received baggage 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 the baggage L and the operation of delivering another baggage L in parallel. In other words, the baggage L can be received from the drone D one after another while minimizing the stop time of the pallet driving device 5. This makes it possible to shorten the time required for the operation of receiving the baggage L from the drone D. In addition, the waiting time of users entering and leaving the parking lot and users receiving the baggage L can be shortened.

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

[0047] It is preferable that the control device 11 specify the landing site using the two-dimensional code 12. This is because the pallet 2 serving as the landing site can be seen from the sky regardless of the height of the pallet 2, 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 be specified by 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 traversable, 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 multi-level parking device 100 of this embodiment is a pit type, the luggage L may be stored on the pallet 2 underground. 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 of the drone D. Other configurations of this embodiment are similar to 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, a case will be described where the pallet 2 circled in Fig. 6(A) is used as the landing site for the drone D. As described above, in case of rainy weather, it is preferable for the control device 11 to designate a pallet 2 below the topmost pallet as the landing site so that the luggage 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 spaces A, B, and C, and then designates it as the landing site.

[0050] First, the operation of step 1 is the same as in the first embodiment. (Step 2) When the two-level parking device 100 receives a landing request signal from the drone D, it prepares the drone D for landing. The drone D can use the empty pallet 2 exposed at the top as a landing site. In other words, even if the pallet 2 is on the first or second floor of the ground in this figure, the drone D can land if the pallet 2 is moved laterally to expose the top surface of the pallet 2 above the two-level parking device 100. In the example of this figure, the top pallet 2 of the pallet 2 designated as the landing site is moved laterally, so that 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 the drone D to descend along the installation space B and land on the pallet 2 on the second floor of the 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 to expose the upper surface of the pallet 2 to the sky. Other operations in step 2 are similar to 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 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 the parking spaces 3 as landing sites for the drone D. Therefore, it is possible to store luggage L equal to the number of all the empty pallets 2. Furthermore, in rainy weather, 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 pallet 2 above it can be moved onto the pallet 2 carrying the luggage L, thereby protecting the luggage L from the rain.

[0053] Moreover, once the marker (two-dimensional code 12) at the landing site of drone D is installed, it is generally difficult to change it. Conventionally, the landing site of drone D could not be changed unless the marker itself could be moved. However, in the two-level parking device 100 of this embodiment, the pallet 2 with the two-dimensional code 12 attached can be moved, so that 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 can realize a drone port that can respond to changes in the landing location of the drone D by using the movement function of the pallet 2 that existing two-level parking devices normally have and designating the pallet as the landing location of the drone D. The rest of the configuration, operation method, and effects of this embodiment are similar to those of the first embodiment.

[0054] The two-level parking device 100 of the second embodiment is not limited to the above-mentioned configuration. For example, the two-level parking device 100 of the second embodiment may be a puzzle-type two-level parking device in which all pallets can be raised, lowered, and moved sideways, as disclosed in JP 2020-2569 A. In this case, the control device 11 moves the pallet 2 designated as the landing location to a parking space 3 where the unmanned airplane 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 luggage L on a level lower than the top level.

[0055] According to the present invention described above, there are multiple installation spaces A, B, and C, each having 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 a landing location for the unmanned aerial vehicle D. The control device 11 selects one of the pallets 2 that is the topmost and empty among the multiple pallets 2 in each installation space A, B, and C, and designates it as a landing location where the unmanned aerial vehicle D can take off and land. In addition, 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, in the present invention, while the operation of handing over luggage L received at one landing location is being performed, other luggage L can be received at another landing location, so that the operation of receiving and handing over luggage L can be performed in parallel.
