[0002] Current logistics facilities can transport goods using multiple automated electric handling vehicles. These vehicles can transport goods between multiple handling stations. Electric handling vehicles require electricity to move. It should be noted that current logistics facilities provide fixed charging stations. Due to queuing, electric handling vehicles often waste significant time queuing at charging locations and traveling back and forth to charging stations, resulting in decreased transport efficiency. Therefore, increasing the charging opportunities for electric handling vehicles is one of the key research focuses for those skilled in the art in order to improve transport efficiency in logistics facilities. [Summary of the Invention]

Implementation Method

[0007] Some embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Component symbols used in the following description are considered to be the same or similar components when they appear in different drawings. These embodiments are only a part of the present invention and do not disclose all possible implementations of the invention. More precisely, these embodiments are merely examples within the scope of the present invention's patent application.

[0008] Please refer to Figures 1 and 2. Figure 1 is a schematic diagram of a transportation system according to an embodiment of the present invention. Figure 2 is a schematic diagram of an operation method according to an embodiment of the present invention. In this embodiment, the transportation system 100 includes electric handling vehicles 110_1~110_3, wireless charging devices 120_1~120_n, and a host 130. The host 130 executes operation method S100. The host 130 executes multiple instructions of operation method S100.

[0009] In this embodiment, the operation method S100 includes steps S110 to S150. In step S110, the host 130 defines a movable area AA in the field based on the layout of the field. For example, the host 130 can receive a layout file of the field. The host 130 can define the movable area AA in the field based on the layout file of the field.

[0010] In step S120, the host 130 sets up transport stations ST1 to ST5 for the electric transport vehicles 110_1 to 110_3 in the movable area AA. For example, the locations of transport stations ST1 to ST5 are respectively adjacent to the locations of shelves in the area. The electric transport vehicles 110_1 to 110_3 take goods from the shelves at transport stations ST1 to ST5, or move goods onto the shelves at transport stations ST1 to ST5. Therefore, the host 130 obtains the locations of the shelves in the area based on the layout file of the area, and sets up transport stations ST1 to ST5 based on the locations of the shelves in the area.

[0011] In step S130, the host 130 establishes transport paths P1~P10 between transport stations ST1~ST5 based on multiple shortest distances between transport stations ST1~ST5. Electric transport vehicles 110_1~110_3 can move on transport paths P1~P10.

[0012] In step S140, the host 130 defines multiple wireless charging locations at multiple positions adjacent to transport stations ST1-ST5 on transport paths P1-P10 and at the intersections of the multiple transport paths. In step S150, the host 130 controls at least one of the electric transport vehicles 110_1-110_3 to move the wireless charging devices 120_1-120_n to the multiple wireless charging locations. That is, once the multiple wireless charging locations are determined, at least one of the electric transport vehicles 110_1-110_3 is controlled to transport the wireless charging devices 120_1-120_n to the multiple wireless charging locations.

[0013] It is worth mentioning that the host 130 establishes transport paths P1-P10 between transport stations ST1-ST5 based on at least one shortest distance between them, and defines multiple wireless charging locations at multiple positions adjacent to transport stations ST1-ST5 and at the intersections of transport paths P1-P10. Therefore, when electric transport vehicles 110_1-110_3 pass by or stop at a wireless charging location on transport paths P1-P10, the transport system 100 can wirelessly charge the electric transport vehicles 110_1-110_3. The charging opportunities for electric transport vehicles 110_1-110_3 are increased. In this way, the transport efficiency of the site can be improved.

[0014] In this embodiment, the wireless charging devices 120_1~120_n are placed on the ground along the transport paths P1~P10 and are approximately flush with the ground. That is, in terms of layout, the transport paths P1~P10 partially overlap with the plurality of wireless charging locations. Therefore, the placement of the wireless charging devices 120_1~120_n and the plurality of wireless charging locations further increases the space cost of the site.

[0015] For illustrative purposes, this embodiment uses five transport stations ST1~ST5 as an example and three electric transport vehicles 110_1~110_3 as an example. However, the present invention is not limited to the number of transport stations and the number of electric transport vehicles. In addition, the number of transport paths will also increase with the increase of transport stations.

[0016] Based on the change of the field FD, when the number of transport stations is changed, the host 130 re-executes the operation method S100.

[0017] In this embodiment, the site can be a warehouse or a factory. The electric handling vehicles 110_1 to 110_3 can each be automated guided vehicles (AGVs) with cargo transportation functions. In the site, the electric handling vehicles 110_1 to 110_3 move and transport goods according to the transport paths P1 to P10 provided by the host 130.

[0018] In this embodiment, the host 130 may be implemented by an electronic device with computing capabilities. For example, the host 130 may be a server, personal computer, laptop computer, tablet computer, smartphone, or other mobile device.

[0019] Please refer to Figure 3, which is a circuit block diagram of a transportation system according to an embodiment of the present invention. This embodiment uses an electric transport vehicle 110_1, a wireless charging device 120_1, and a host 130 of the transportation system 100 as examples. In this embodiment, the wireless charging device 120_1 includes a wireless charger 121 and a charging controller 122. The wireless charger 121 receives mains power PEX and outputs wireless power WPM based on the mains power PEX. In this embodiment, the wireless charger 121 can convert the mains power PEX into wireless power WPM and send the wireless power WPM to the electric transport vehicle 110_1 in an inductive coupling manner. Therefore, once the electric transport vehicle 110_1 passes by the wireless charging device 120_1 or stays near the wireless charging device 120_1, the wireless charger 121 can wirelessly charge the electric transport vehicle 110_1.

[0020] The charging controller 122 is connected to the wireless charger 121. The charging controller 122 provides the wireless charging device 120_1's information MG1 to the host 130. The wireless charging device 120_1's information MG1 includes the location of the wireless charger 121 and the usage status of the wireless charger 121. For example, the usage status of the wireless charger 121 includes the supply status and power of the wireless power supply (WPM).

[0021] In this embodiment, the electric transport vehicle 110_1 includes a battery module 111 and a wireless power receiver 112. The wireless power receiver 112 is connected to the battery module 111. The wireless power receiver 112 receives wireless power (WPM) from the wireless charger 121 via inductive coupling and uses the wireless power (WPM) to charge the battery module 111. In this embodiment, the battery module 111 is implemented using an aluminum-ion battery. Therefore, the battery module 111 has a high charging speed and a high discharging speed.

[0022] The electric handling vehicle 110_1 also includes a motor 113 and a power converter 114. The electric handling vehicle 110_1 moves based on the operation of the motor 113. The power converter 114 is connected to the battery module 111 and the motor 113. The power converter 114 converts the battery power PB stored in the battery module 111 into a drive power PDR, and uses the drive power PDR to drive the motor 113.

[0023] The electric transport vehicle 110_1 also includes a vehicle controller 115. The vehicle controller 115 is connected to the power converter 114 and the wireless power receiver 112. The vehicle controller 115 provides information MG2 of the electric transport vehicle 110_1 to the host 130. The information MG2 of the electric transport vehicle 110_1 includes the position of the electric transport vehicle 110_1 and the usage status of the electric transport vehicle 110_1. For example, the usage status of the electric transport vehicle 110_1 includes the usage status of the power converter 114 and the wireless power receiver 112. The host 130 can also know the power level of the battery module 111 via the wireless power receiver 112, and know the operating status of the motor 113 (e.g., running time and speed) via the power converter 114. In addition, the vehicle controller 115 can receive control signals SC from the host 130. The vehicle controller 115 controls the electric transport vehicle 110_1 to move within one of the transport paths P1 to P10 (e.g., a designated transport path) based on the control signal SC. The vehicle controller 115 can also control the charging speed of the battery module 111 and / or the rotational speed of the motor 113 based on the control signal SC.

[0024] In this embodiment, the host 130 includes a message transmission circuit 131 and a calculation circuit 132. The calculation circuit 132 executes operation method S100. Furthermore, the message transmission circuit 131 receives message MG2 from the electric transport vehicle 110_1 and message MG1 from the wireless charging device 120_1. The calculation circuit 132 is connected to the message transmission circuit 131. The calculation circuit 132 adjusts at least one of the following based on messages from the charging controller 122 and the vehicle controller 115: the plurality of wireless charging locations, the designated transport path of the electric transport vehicle 110_1, the number of electric transport vehicles, and the range of the mains power transmission area.

[0025] In this embodiment, the host 130 further includes a data output circuit 133. The data output circuit 133 is connected to the arithmetic circuit 132. The data output circuit 133 stores and outputs at least one of the following: the message MG2 of the electric transport vehicle 110_1, the message MG1 of the wireless charging device 120_1, the plurality of wireless charging locations, the designated transport path of the electric transport vehicle 110_1, the number of electric transport vehicles, and the range of the mains power transmission area.

[0026] In this embodiment, the message transmission circuit 131 communicates wirelessly with the vehicle controller 115 and the charging controller 122 according to any protocol. In some embodiments, the message transmission circuit 131 can communicate wiredly with the vehicle controller 115 and the charging controller 122.

[0027] In this embodiment, the arithmetic circuit 132 is, for example, a central processing unit (CPU), or other programmable general-purpose or special-purpose microprocessor, digital signal processor (DSP), programmable controller, application specific integrated circuit (ASIC), programmable logic device (PLD) or other similar device or combination of these devices, which can load and execute computer programs.

[0028] Please refer to Figures 1, 2, and 4. Figure 4 is a schematic diagram illustrating steps S110 and S120 according to an embodiment of the present invention. The field FD is divided into multiple unit areas. Each of the multiple unit areas has a different address. The host 130 can identify the location of the transport stations ST1~ST5, the location of the transport paths P1~P10, and the location of the wireless charging location based on the multiple unit areas. In step S110, the host 130 defines prohibited movement areas AD1 and AD2 in the field FD according to the layout of the field FD. The prohibited movement areas AD1 and AD2 are areas that the electric transport vehicles 110_1~110_3 cannot enter. The host 130 defines the area outside the prohibited movement areas AD1 and AD2 as the movable area AA. In step S120, the host 130 sets the transport stations ST1~ST5 in the movable area AA.

[0029] Please refer to Figures 1, 2, and 5. Figure 5 is an operational schematic diagram of step S130 according to an embodiment of the present invention. The host 130 establishes transport paths P1 to P10 between transport stations ST1 to ST5 based on multiple shortest distances between transport stations ST1 to ST5. For example, there is a first shortest distance between transport station ST1 and transport station ST2. The distance of transport path P1 between transport station ST1 and transport station ST2 is equal to the first shortest distance. There is a second shortest distance between transport station ST1 and transport station ST3. The distance of transport path P2 between transport station ST1 and transport station ST3 is equal to the second shortest distance. There is a third shortest distance between transport station ST1 and transport station ST4. The distance of transport path P3 between transport station ST1 and transport station ST4 is equal to the third shortest distance, and so on. The first shortest distance may be the same as or different from the second shortest distance. The first shortest distance may be the same as or different from the third shortest distance, and so on. Therefore, the distances of transport paths P1 to P10 may not be exactly the same.

[0030] Please refer to Figures 1, 2, and 6. Figure 6 is a schematic diagram illustrating the establishment of a new road segment according to an embodiment of the present invention. The host 130 can also decide whether to establish a new road segment. Taking the electric transport vehicle 110_1 as an example, the host 130 also determines the number of times the electric transport vehicle 110_1 avoids other electric transport vehicles (e.g., electric transport vehicles 110_2, 110_3) on the road segment PS1 of the transport path P1. After the transport paths P1~P10 are established, the host 130 can obtain the above-mentioned number of times through simulation. When the number is greater than a set number, it indicates that the road segment PS1 is relatively congested. Therefore, the host 130 establishes a new road segment PS1'. The new road segment PS1' is parallel to the road segment PS1. When the number is less than or equal to the set number, it indicates that the road segment PS1 is not congested. The host 130 does not establish a new road segment PS1'.

[0031] Please refer to Figures 1, 2, and 7. Figure 7 is an operational schematic diagram of step S140 according to an embodiment of the present invention. The host 130 defines wireless charging positions PO1 to PO8 at multiple locations adjacent to transport stations ST1 to ST5 on transport paths P1 to P10 and at the intersections of transport paths P1 to P10. Wireless charging positions PO1 to PO5 are respectively adjacent to one of transport stations ST1 to ST5. Wireless charging positions PO6 to PO8 are respectively located at one of the intersections.

[0032] Next, the host 130 can control the electric transport carrier 110_1 to transport eight wireless charging devices 120_1 to 120_n to wireless charging positions PO1 to PO8. For example, wireless charging device 120_1 is placed in wireless charging position PO1. Wireless charging device 120_2 is placed in wireless charging position PO2, and so on.

[0033] In some embodiments, the host 130 can control multiple electric transport vehicles to transport eight wireless charging devices among the wireless charging devices 120_1~120_n to wireless charging locations PO1~PO8.

[0034] In this embodiment, segment PS1 on the transport path P1 is located between wireless charging location PO6 and wireless charging location PO7. Therefore, the newly added segment PS1' is also established between wireless charging location PO6 and wireless charging location PO7.

[0035] In this embodiment, the host 130 can decide to allocate one to five electric transport vehicles to the field FD. For example, electric transport vehicle 110_1 is allocated to the field FD. Electric transport vehicle 110_1 runs along the transport path P2. Therefore, when electric transport vehicle 110_1 passes through or stops at wireless charging positions PO1, PO6, PO7, and PO3, the host 130 controls the wireless charging devices located at wireless charging positions PO1, PO6, PO7, and PO3 to wirelessly charge electric transport vehicle 110_1.

[0036] Please refer to Figures 1 and 8A. Figure 8A is a schematic diagram of a mains power transmission area according to an embodiment of the present invention. In this embodiment, the host 130 adjusts the range of the mains power transmission area AG1 according to the transport paths P1 to P10. The wireless charging devices set at the wireless charging positions PO1 to PO8 can provide wireless power based on the mains power from the mains power transmission area AG1. In this embodiment, the range of the mains power transmission area AG1 is approximately equal to the range surrounded by the transport stations ST1 to ST5 in the movable area AA, and includes the range of the transport paths P1 to P10.

[0037] In this embodiment, when the transport path P1~P10 or the transfer station ST1~ST5 are frequently changed, the range of the mains power transmission area AG1 is shown in Figure 8A.

[0038] Please refer to Figures 1 and 8B. Figure 8B is a schematic diagram of the mains power transmission area according to an embodiment of the present invention. In this embodiment, when the transport paths P1~P10 or the transfer stations ST1~ST5 are not frequently changed, the range of the mains power transmission area AG2 is as shown in Figure 8B. The range of the mains power transmission area AG2 is smaller than the range of the mains power transmission area AG1 shown in Figure 8A.

[0039] Please refer to Figures 1 and 9. Figure 9 is a schematic diagram illustrating a wireless charging device and a wireless charging location according to an embodiment of the present invention. Figure 9 shows a wireless charging device 220 and a wireless charging location PO. The wireless charging device 220 includes a circuit module CC, a communication element 223, a power transmission coil LP, and a magnetic structure 224. The circuit module CC generates wireless power WPM based on the mains power PEX. The circuit module CC includes a converter and a controller (not shown). The function of the controller is substantially the same as that of the charging controller 122 shown in Figure 3. The charging controller of the wireless charging device 220 can wirelessly communicate with the host 130 via the communication element 223. The converter receives the mains power PEX and converts the mains power PEX into wireless power WPM. The power transmission coil LP is connected to the circuit module CC. The power transmission coil LP outputs wireless power WPM. The functions of the converter and the power transmission coil LP are substantially the same as those of the wireless charger 121 shown in Figure 3.

[0040] The communication element 223, the power transmission coil LP, and the magnetic structure 224 are respectively disposed on the first surface of the circuit module CC. Therefore, the magnetic structure 224 is located between the power transmission coil LP and the circuit module CC. The magnetic structure 224 can concentrate the magnetic field generated by the power transmission coil LP. The directionality of the magnetic field is enhanced. Therefore, the directionality of the wireless power WPM transmission is improved. The magnetic structure 224 can prevent the circuit module CC from being affected by the magnetic field generated by the power transmission coil LP.

[0041] The wireless charging device 220 includes mains contact structures CT1 and CT2. The mains contact structures CT1 and CT2 are disposed on the second side of the circuit module CC. The second side is opposite to the first side.

[0042] In this embodiment, cables CB1 and CB2 for transmitting mains power PEX are disposed underground in the field. Each unit area of ​​the field has a groove. The groove has through-holes H1 and H2. When the wireless charging device 220 is moved to the wireless charging position PO, the wireless charging device 220 is placed in the groove corresponding to the wireless charging position PO. The mains power contact structure CT1 contacts cable CB1 via through-hole H1. The mains power contact structure CT2 contacts cable CB2 via through-hole H2. Therefore, the wireless charging device 220 receives mains power PEX.

[0043] Furthermore, when the wireless charging device 220 is placed in the groove corresponding to the wireless charging position PO, the first surface of the circuit module CC is flush with the ground GD of the field.

[0044] In some embodiments, when the wireless charging device 220 is placed in the groove corresponding to the wireless charging position PO, the power transmission coil LP is flush with the ground GD of the field.

[0045] In some embodiments, the wireless charging device 220 may include a protective cover (not shown). When the wireless charging device 220 is placed in a recess corresponding to the wireless charging position PO, the protective cover is flush with the ground GD of the field.

[0046] In this embodiment, the wireless charging device 220 includes a magnetically conductive structure 224. Therefore, to remove the wireless charging device 220 placed in the recess, the electric transport carrier 110_1 can use magnetic force to remove the wireless charging device 220 placed in the recess. In some embodiments, the electric transport carrier 110_1 can also use a suitable clamping mechanism to remove the wireless charging device 220 placed in the recess.

[0047] In this embodiment, the wireless charging device 220 can be one of the wireless charging devices 120_1 to 120_n.

[0048] In summary, the operating method and transportation system establish multiple transport paths between the multiple transport stations based on at least one shortest distance between them, and define multiple wireless charging locations at multiple positions adjacent to the multiple transport stations and at the intersections of the multiple transport paths. Therefore, when the electric transport vehicle passes through or stops at a wireless charging location on a transport path, the transportation system can wirelessly charge the electric transport vehicle. The charging opportunities for the electric transport vehicle are increased. In this way, the transportation efficiency of the logistics area can be improved.

[0049] Although the present invention has been disclosed above by way of embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims. [Simplified Explanation of the Diagram]
