Description

Drone delivery receiving system

[0001] The present invention relates to a parcel receiving system, and more specifically, to a drone parcel receiving system for receiving parcels delivered by a drone.

[0002] With the recent rapid growth of the e-commerce market and the proliferation of contactless services, various technological initiatives are being undertaken to enhance the efficiency and safety of parcel delivery logistics systems. In particular, drone delivery technology is garnering attention as a faster and more cost-effective means of goods delivery compared to traditional ground logistics systems, and its potential for use is significantly increasing not only in urban areas but also in regions with poor transportation access. While drone delivery offers the advantage of delivering goods regardless of the recipient's location, a receiving system capable of safely and quickly delivering items is essential for its effective implementation.

[0003] Existing drone delivery systems typically presented the inconvenience of requiring recipients to go outside to pick up items in person or manually retrieve them from specific landing sites. Additionally, issues such as security concerns during landing, the risk of loss or damage during delivery, and instability due to weather conditions also existed.

[0004] The present invention aims to provide a system that allows for the safe receipt of parcels delivered by drone through a smart container installed on a building window railing.

[0005] Specifically, the present invention was developed to solve the problems of the aforementioned prior art, and the objective of the present invention is to provide a drone parcel receiving system that can promote the commercialization of drone logistics by comprehensively improving the convenience, safety, and efficiency of a drone delivery system.

[0006] As a means for solving the above-mentioned problem, a drone delivery receiving system according to the disclosure of the present invention is a drone delivery receiving system for receiving delivery items transported via a drone mounted on a window railing of a building, and may include: a smart container installed on a window railing and having an internal storage space for storing delivery items; a power supply unit mounted on the smart container and supplying independent power to the smart container; a control unit that communicates with a drone or a user terminal device and outputs a control signal that controls the opening, closing, and movement of the smart container according to a signal from the drone or the user terminal device; and a driving unit that opens, closes, or moves the smart container according to the control signal output from the control unit.

[0007] The above power supply unit can store electricity generated by the solar panel in a capacitor and supply the stored electricity to the smart container.

[0008] The above drone delivery receiving system may further include a temperature control unit installed inside the smart container and receiving power from the power supply unit to control the internal temperature of the smart container.

[0009] The above control unit can detect the approach of a drone through wireless communication with one or more drones and output a control signal to control the opening and closing of the smart container when the drone approaches.

[0010] The smart container described above can be configured to change shape between a folded state with reduced volume and an unfolded state for storing packages.

[0011] When a request to discharge a stored parcel is received from a user terminal device, the control unit can control the smart container to rotate to a position where the user can receive the parcel, and open the smart container to discharge the stored parcel.

[0012] The above control unit can notify the user terminal device of the receipt of a delivery item when it receives a delivery item delivered by a drone.

[0013] The above control unit outputs a control signal to control the cover to be closed upon receipt of a delivery item delivered by a drone, and

[0014] The smart container described above may include a sealed structure designed to protect against external environmental factors.

[0015] The above control unit can output a control signal to control the opening and closing of the smart container by switching it to a protection mode during adverse weather conditions, including rain, snow, or strong winds.

[0016] The above control unit can determine the receiving order of delivery items delivered by multiple drones when multiple drones approach simultaneously, and output a control signal to control the approach of multiple drones according to the determined receiving order.

[0017] The present invention provides a drone parcel receiving system that solves problems arising from parcel delivery using drones and simultaneously improves user convenience and system safety, and exhibits the following effects of the invention.

[0018] First, the present invention provides an environment in which users can safely receive items indoors without having to go outside, through a smart container installed on a building window railing. When a drone approaches, the smart container automatically opens and rotates or slides inward at the user's request, allowing for easy retrieval of items. Through this function, users do not need to be exposed to the external environment, and even children and the elderly can safely receive packages.

[0019] Secondly, the present invention can effectively protect delivery items from the external environment. The smart container is designed with a sealed structure to prevent damage to items from external environmental factors such as rain, snow, and strong winds, and automatically switches to a protection mode via an environmental detection sensor when weather conditions deteriorate. This enhances the landing safety of the drone and reduces the risk of damage to the items.

[0020] Thirdly, the present invention enables continuous power supply by including an independent power system utilizing solar panels. The power supply unit stores electricity generated from sunlight in a capacitor and supplies power to the drive and control units inside the container when necessary. This allows the system to operate stably for a long period, even in environments where external power supply is difficult.

[0021] Fourth, the present invention enables the sequential delivery or receipt of goods without collision even when multiple drones approach simultaneously through a multi-drone support function. The control unit determines the order of receipt based on the drone's arrival time, the importance of the goods, and battery status, and efficiently manages the movement between drones. As a result, logistics processing speed is improved, and stable operation is possible even in large-scale logistics networks.

[0022] In addition, the system of the present invention can maintain the freshness of goods by storing special cargo, such as fresh food, at an appropriate temperature through a temperature control unit. User convenience is significantly improved as the user can check and control the status of the goods in real time via a mobile terminal.

[0023] Therefore, the present invention solves various problems that may occur during the drone delivery receiving process and provides users with a safe and efficient product receiving environment, thereby exhibiting significant technical effects that can promote the commercialization of logistics systems utilizing drones.

[0039] According to hardware implementation, the embodiments described herein may be implemented using at least one of ASICs (application specific integrated circuits), DSPs (digital signal processors), DSPDs (digital signal processing devices), PLDs (programmable logic devices), FPGAs (field programmable gate arrays), processors, controllers, microcontrollers, microprocessors, and electrical units for performing functions.

[0040] According to the software implementation, embodiments such as procedures or functions may be implemented together with separate software modules that perform at least one function or operation. The software code may be implemented by a software application written in a suitable programming language.

[0041] FIG. 1 is a block diagram showing the configuration of a drone delivery receiving system (100) according to one embodiment of the present invention.

[0042] The drone delivery receiving system (100) includes a smart container (110). The smart container (110) is installed on a window railing of a building and configured to safely and efficiently receive delivery items delivered by a drone. The smart container (110) provides a storage space inside for storing delivery items.

[0043] The power supply unit (120) is a component for supplying independent power to the smart container (110), storing electricity generated through a solar panel in a capacitor and supplying power to each component of the container when needed. This allows the system to operate continuously for a long period without an external power supply.

[0044] The control unit (130) performs wireless communication with the drone or user terminal device, detects the approach of the drone, and outputs control signals for each component of the system (100). The control unit (130) controls the operation to ensure safety by adjusting the opening and closing state of the smart container when the drone approaches and switching to a protection mode in case of bad weather.

[0045] The drive unit (140) is responsible for opening, closing, or moving the smart container (110) according to a signal output from the control unit (130). The drive unit may be composed of mechanisms such as an electric motor, a hinge, or a rail, and when a user requests it through a mobile application, the container rotates or slides to move to a position where goods can be received.

[0046] The temperature control unit (150) is installed inside the smart container (110) and provides the function of controlling the internal temperature to maintain the freshness of the parcel being stored. The temperature control unit (150) includes a cooling device and a temperature sensor and operates automatically according to user or environmental conditions through the control unit (130). This enables long-term storage of items such as fresh food.

[0047] The drone delivery receiving system (100) provides a convenient item receiving environment for the user through real-time communication and control with the drone, and can safely protect the items from external environmental factors. In addition, efficient energy management and storage conditions can be optimized through the energy self-sufficiency system of the power supply unit (120) and the temperature control unit (150).

[0048] Below, each component of the drone delivery receiving system (100) is described in detail.

[0049] [Power supply unit (120)]

[0050] The drone delivery receiving system (100) includes a power supply unit (120) to enable stable operation even in environments where power supply is not smooth. The power supply unit (120) generates electricity using a solar panel, stores the generated electricity in a capacitor, and then supplies power to each component as needed.

[0051] The power supply unit (120) may include a solar panel, a converter, and a capacitor.

[0052] Solar panels convert external solar energy into electrical energy. In this invention, a panel composed of high-efficiency solar cells is used to be designed to generate sufficient power even in low-light environments. The panel is installed on the exterior of a residential window railing and positioned at an angle to maximize solar absorption. A transparent protective layer is applied to the surface of the panel to protect it from external environmental factors, and this protective layer is composed of a material with durability and UV blocking capabilities.

[0053] Direct current (DC) power generated from the solar panel is transferred to a converter within the power supply unit (120). The converter converts the power generated from the panel into a stable voltage and current and supplies it according to the power specifications required by each component of the smart container (110). In this process, a power stabilization circuit may be included to prevent damage caused by overvoltage or fluctuations in current.

[0054] The converted power is stored in a capacitor (battery). The capacitor may consist of a lithium-ion battery or a lithium iron phosphate battery, and can stably store and release power for a long time. The capacitor can continuously supply power even in a standby mode with low power consumption, and ensures the normal operation of the container even at night when sunlight is insufficient or in cloudy weather. The remaining battery level is transmitted to the control unit (130) in real time for management, and the charging status can be checked via a user terminal if necessary.

[0055] Additionally, the power supply unit (120) includes a Power Management System to maximize energy efficiency. This system sets power usage priorities so that each component, such as the drive unit (140), control unit (130), and temperature control unit (150), can use power efficiently. For example, when no items are stored, the operation of the temperature control unit (150) is stopped or switched to a power-saving mode to reduce unnecessary power consumption.

[0056] [Control unit (130)]

[0057] The control unit (130) detects the approach of the drone, controls the operation of the smart container through the drive unit (140), and can manage the process of receiving goods through communication with the user terminal device.

[0058] The control unit (130) detects the approach status of the drone through wireless communication with the drone and performs necessary control commands. Communication with the drone can be performed through various wireless communication methods such as RFID, Bluetooth, Wi-Fi, or UWB (Ultra-Wideband). When the drone approaches a signal recognition device mounted on the smart container, the control unit (130) receives the drone's signal and checks whether the drone has the authority to perform a designated delivery task. Once signal verification is complete, the control unit (130) can output a control signal to the drive unit (140) to open the lid of the smart container.

[0059] When the drone safely places the delivery item inside the smart container, the control unit (130) checks whether the item has been properly stored using an internal sensor (e.g., a weight sensor or an infrared detection sensor). Afterward, it commands the drive unit (140) to close the cover so that the item can be protected from the external environment. If bad weather is detected or the drone fails to place the item correctly, the control unit (130) may stop the opening and closing operation and send a notification to the user.

[0060] The control unit (130) controls the smart container (110) to move to an appropriate location in conjunction with the drive unit (140). For example, when a user requests to receive a delivery item via a mobile application, the control unit (130) commands the drive unit (140) to rotate or slide the smart container (110) to a location accessible to the user. This movement is performed through an internal motor and gear system and is precisely controlled by a position sensor and a limit switch. The drive unit (140) performs the movement and opening / closing of the smart container (110) according to the control signal of the control unit (130).

[0061] After the delivery item is received, the control unit (130) notifies the user in real time of the item receipt status through communication with the user terminal device. The control unit (130) sends a notification to the user via a mobile application and manages the procedure to verify whether the user has safely received the item. The user can monitor the status of the container through the terminal device or send a command to receive additional items. This communication can also be performed remotely as long as the network connection is maintained stably, allowing the user to check the delivery status anytime and anywhere.

[0062] Additionally, the control unit (130) can continuously monitor data from the environment sensing sensor and switch to a protection mode according to the weather conditions. For example, if strong winds or heavy rain are detected, the control unit commands the drive unit (140) to keep the smart container (110) in a folded state and temporarily suspends additional delivery operations to ensure the safety of the system.

[0063] [Driver (140)]

[0064] The drive unit (140) can drive the smart container (110) according to the approach of the drone, the receipt of delivery items, and user requests. The drive unit (140) may include an electric motor, a hinge mechanism, a sliding rail, a position sensor, and a limit switch, and performs various operations according to a control signal from the control unit (130).

[0065] When the drone approaches the smart container (110), the control unit (130) receives a signal from the drone and outputs a command to the drive unit (140) to open the lid of the smart container. Accordingly, the electric motor of the drive unit (140) operates so that the lid of the smart container opens automatically. At this time, the hinge mechanism and the position sensor mounted on the drive unit (140) monitor the opening angle of the lid in real time to precisely control the lid so that it does not open or close excessively. When the lid is fully opened, the drone can safely place goods into the smart container (110).

[0066] When bad weather or strong winds are detected, the control unit (130) commands the drive unit (140) to restrict the opening and closing operation, and the drive unit (130) closes the cover and switches the smart container (110) to a protection mode state. This allows the goods and the smart container (110) to be protected from external environmental factors even when a drone approaches.

[0067] When the drone places a delivery item inside the smart container (110), the control unit (130) checks through an internal sensor whether the item is stored correctly. Then, the control unit (130) issues a command to the drive unit (140) to close the cover, and the electric motor of the drive unit (140) operates again to close the cover. Even during the process of closing the cover, the position sensor and the limit switch are linked to ensure that the cover is closed correctly and the sealed state is maintained.

[0068] The drive unit (140) is designed to operate smoothly and stably so that the item is not damaged by external impact or environmental factors. In particular, the drive mechanism with a sealed structure prevents external dust, water, and wind from penetrating into the smart container (110), thereby optimizing the storage condition of the item.

[0069] When a user requests to receive a delivery item through a mobile application, the control unit (130) outputs a command to the drive unit (140) to move the smart container (110) to a location accessible to the user. The drive unit (140) rotates or slides the smart container (110) from the outside of the railing to the inside in accordance with this command. At this time, the electric drive device and the guide rail work together to allow the smart container (110) to move smoothly and accurately.

[0070] After the smart container (110) moves to the user access position, the lid is automatically opened so that the user can safely take out the item. When the user receives the item, an internal sensor detects this and transmits a signal to the control unit (130) indicating that the item has been received. The driving unit (140) moves the smart container (110) to its initial position and maintains it in a standby state.

[0071] The drive unit (140) provides various functions to maintain safety and precision at each operation stage. A position sensor monitors the opening, closing, and movement positions of the container in real time, and a limit switch controls the operation so as not to exceed the operating range. In addition, the drive unit (140) includes an overload protection device to immediately stop operation if an excessive load occurs on the drive unit, thereby preventing damage to the system.

[0072] FIG. 2 is a block diagram illustrating an example of a computer device (200) according to an embodiment of the present invention. The control unit (130) described above may be implemented by the computer device (200) shown in FIG. 2, and a control method according to embodiments of the present invention may be performed by such a computer device (200).

[0073] At this time, as illustrated in FIG. 2, the computer device (200) may include memory (210), a processor (220), a communication interface (230), and an input / output interface (240). The memory (210) is a computer-readable recording medium and may include a non-perishable mass storage device such as RAM (random access memory), ROM (read only memory), and a disk drive. Here, the non-perishable mass storage device such as ROM and the disk drive may be included in the computer device (200) as a separate permanent storage device distinct from the memory (210).

[0074] Additionally, an operating system and at least one program code may be stored in the memory (210). These software components may be loaded into the memory (210) from a computer-readable recording medium separate from the memory (210). This separate computer-readable recording medium may include computer-readable recording media such as a floppy drive, disk, tape, DVD / CD-ROM drive, or memory card. In another embodiment, the software components may be loaded into the memory (210) via a communication interface (230) rather than a computer-readable recording medium. For example, the software components may be loaded into the memory (210) of the computer device (100) based on a computer program installed by files received through the network (170).

[0075] The processor (220) may be configured to process instructions of a computer program by performing basic arithmetic, logic, and input / output operations. Instructions may be provided to the processor (220) via memory (210) or a communication interface (230). For example, the processor (220) may be configured to execute instructions received according to program code stored in a recording device such as memory (210).

[0076] The communication interface (230) may provide a function for the computer device (200) to communicate with other devices (e.g., storage devices described above) through the network (170). For example, requests, commands, data, files, etc. generated by the processor (220) of the computer device (200) according to program code stored in a recording device such as memory (210) may be transmitted to other devices through the network (170) under the control of the communication interface (230). Conversely, signals, commands, data, files, etc. from other devices may be received by the computer device (200) through the communication interface (230) of the computer device (200) via the network (170). Signals, commands, data, etc. received through the communication interface (230) may be transmitted to the processor (220) or memory (210), and files, etc. may be stored in a storage medium (the permanent storage device described above) that the computer device (200) may further include.

[0077] The input / output interface (240) may be a means for interfacing with an input / output device (250). For example, the input device may include a device such as a microphone, keyboard, camera, or mouse, and the output device may include a device such as a display or speaker. As another example, the input / output interface (240) may be a means for interfacing with a device in which the functions for input and output are integrated into one, such as a touchscreen. The input / output device (250) may be composed of a computer device (200) and a single device.

[0078] Additionally, in other embodiments, the computer device (200) may include fewer or more components than the components of FIG. 2. However, it is not necessary to clearly illustrate most of the prior art components. For example, the computer device (200) may be implemented to include at least some of the input / output devices (250) described above, or may include other components such as a transceiver, a database, etc.

[0079] FIG. 3 is a drawing showing the state in which a smart container (110) of a drone delivery receiving system (100) according to one embodiment of the present invention is installed on a house window railing.

[0080] The smart container (110) is equipped with a solar panel (121) on the front so that it can safely receive and store delivery items transported by drone and operate independently for a long period without an external power supply.

[0081] The smart container (110) is fixedly installed on the outer railing of a window in a residential area and is designed to allow a drone to easily deliver goods. A solar panel (121) is installed on the front of the container, and the solar panel (121) converts external solar energy into electrical energy. The solar panel (121) is composed of high-efficiency solar cells, so it can stably produce electricity even in low light environments.

[0082] Electricity generated from the solar panel (121) is stored in a storage battery (battery) installed inside the container. The storage battery stores solar energy and supplies power to the drive unit (140), control unit (130), and temperature control unit (150), which are the main components of the smart container (110). This allows the smart container (110) to operate continuously even in environments where external power supply is difficult. A power converter is installed between the panel and the storage battery to adjust the voltage and current, thereby optimizing power efficiency.

[0083] The solar panel (121) of the smart container (110) may include a transparent protective layer with enhanced durability to protect it from external environmental factors. The transparent protective layer prevents damage to the panel caused by rain, snow, wind, etc., and extends the lifespan of the panel through a UV blocking function.

[0084] When there are no items stored inside the smart container (110), the external exposure area is minimized so that it can be maintained in a folded state as shown in FIG. 3.

[0085] FIG. 4 is a drawing showing the state in which a drone (300) loads goods at a logistics center and moves to a delivery address.

[0086] The drone delivery receiving system (100) can provide fast and stable logistics services by utilizing a drone (300) to quickly and efficiently connect a logistics center and a receiving address.

[0087] The drone (300) loads the goods to be delivered into the storage box (400) at the logistics center. The drone (300) safely loads the designated goods at the logistics center and stores them in the storage box (400) equipped with a fixing system so that the goods are not damaged. The storage box (400) is attached to the bottom of the drone (300) and is designed to minimize shaking of the goods during movement.

[0088] The drone (300) moves to the delivery address after loading the goods. During this process, the drone flies along the optimal path using a GPS-based location tracking system and an autonomous flight control system. The drone continuously monitors the surrounding environment even while flying and can adjust its path in real time according to obstacles or weather conditions. In particular, the drone automatically controls its flight altitude and speed to ensure safe flight.

[0089] The drone (300) and the control unit (130) communicate in real time to share information such as flight status, battery level, and item status. When necessary, the drone (300) transmits status information to a logistics center or user terminal device to support the smooth maintenance of logistics flow.

[0090] FIG. 5 is a diagram showing the state in which a drone (300) approaches a smart container (110) of a drone delivery receiving system (100) according to one embodiment of the present invention. The drone (300) arrives near the delivery location carrying the goods to be delivered, and proceeds with the goods receiving procedure through wireless communication with the control unit (130) of the smart container (110).

[0091] After arriving at the delivery address, the drone (300) communicates in real-time with the control unit (130) to transmit its location and verify the location of the smart container (110). This communication is carried out through various wireless communication technologies such as RFID, Bluetooth, Wi-Fi, or Ultra-Wideband (UWB), and the drone (300) and the smart container (110) determine the exact location through mutual signal exchange. When the drone (300) approaches the designated location, the control unit (130) checks the status of the smart container (110) and then sends a command to the drive unit (140) to control the opening of the cover.

[0092] FIG. 6 is a diagram showing the state in which the lid (111) of the smart container is opened after the drone (300) approaches the smart container (110) according to one embodiment of the present invention. This state is a preparatory step for the drone (300) to safely deliver goods, and mutual communication and control are performed between the drone (300) and the drone delivery receiving system (100).

[0093] After arriving at the delivery address, the drone (300) communicates wirelessly with the control unit (130) to notify of its approach. The control unit (130) receives the signal from the drone (300), and when the approach of the drone (300) is confirmed, it outputs a control signal to the drive unit (140) to open the cover (111) of the smart container (110). Accordingly, the drive unit (140) operates so that the cover (111) is opened by rotation or sliding. During this process, a position sensor detects the opening angle of the cover in real time and controls the cover so that it is safely opened and fixed in a designated position.

[0094] When the cover (111) is fully opened, the drone (300) prepares to put the delivery items loaded in the storage box (400) mounted on the bottom into the smart container (110).

[0095] FIG. 7 is a drawing showing the state in which the cover (410) of the storage box (400) of the drone (300) is opened and a delivery item is delivered to the smart container (110) according to one embodiment of the present invention.

[0096] When the cover (410) of the storage box (400) is opened, the delivery items stored inside are smoothly transferred into the container. At this time, a gentle slope is formed to prevent the items from falling or being damaged during the transfer process, and a loading status detection sensor is installed inside the smart container to continuously monitor the arrangement status of the items.

[0097] When the delivery item is accurately placed in the smart container (110), the control unit (130) checks the loading status and communicates with the drone (300) to notify that the delivery of the item is complete. A loading status detection sensor is installed inside the smart container (110) so that it can check in real time whether the item is placed correctly. If an abnormality occurs during the insertion of the item or if it is not placed correctly, the control unit (130) transmits a warning signal to the drone (300) and the user terminal device to resolve the problem.

[0098] FIG. 8 is a drawing showing the state in which the lid (111) is closed after the delivery item is received in the smart container (110).

[0099] When a delivery item delivered via a drone (300) is placed in a smart container (110), the control unit (130) detects the condition of the item and outputs a command to the drive unit (140) to close the cover (111). Accordingly, the drive unit operates to close the cover, and the inside of the smart container (110) is sealed. During this process, a position sensor and a limit switch are linked to monitor the closed state of the cover (111) in real time and control it so that excessive force or position errors do not occur.

[0100] After the lid (111) is closed, the smart container (110) maintains a sealed structure that protects the goods from the external environment. It prevents external elements such as rain, wind, and dust from penetrating inside, thereby minimizing the risk of damage to the goods. In particular, if the goods are fresh food, the temperature control unit (150) operates to maintain the internal temperature within a set range. For example, for goods requiring refrigeration, the internal temperature is controlled to a range of 0 to 10°C to maintain freshness, and the user can check the internal temperature status in real time through a mobile terminal device.

[0101] The smart container (110) continuously transmits status information in conjunction with a user terminal device while the item is being stored. When a user requests to receive the item via a mobile terminal, the control unit (130) issues a command to the driving unit (140) to move the smart container (110) to a location accessible to the user and open the lid so that the item can be taken out.

[0102] FIG. 9 is a diagram showing the state in which a drone (300) returns to a logistics center after the receipt of a delivery item is completed in a drone delivery receiving system (100) according to one embodiment of the present invention.

[0103] After the drone (300) successfully delivers goods to the smart container (110), it confirms the receipt status through communication with the control unit (130) and receives a command to return to the logistics center. During this process, the smart container (110) is kept closed so that the goods stored inside are safely protected from external environmental factors.

[0104] The drone (300) moves to the logistics center along the optimal route through a GPS-based route guidance system and an autonomous flight control system. During flight, the drone (300) monitors battery status, location information, flight speed, and altitude in real time and can adjust the route if necessary. In addition, through communication functions between drones, it prevents collisions with other drones and continues to fly safely.

[0105] FIG. 10 is a drawing showing the state in which a user receives an item stored in a smart container (110) according to one embodiment of the present invention.

[0106] The user issues a request to receive goods through an application installed on a mobile terminal (500). This request is transmitted to a control unit (130), and the control unit (130) outputs a command to a driving unit (140) so that the smart container (110) moves or rotates toward the user, making it easy for the user to access.

[0107] According to the control signal of the control unit (130), the lid (111) of the smart container (110) is opened, and the user can receive the delivery items stored inside the smart container (110). While the lid (111) is open, a position sensor operates to maintain the opening angle of the lid appropriately, and the drive unit (140) stably controls the movement of the smart container (110) to ensure safety.

[0108] When a user takes out an item, a loading status detection sensor installed inside the smart container (110) confirms that the item has been received. The control unit (130) detects this and sends a notification of item receipt completion to the user terminal (500), and then the smart container (110) closes the lid (111) and switches back to a standby state.

[0109] Accordingly, the user can safely receive the item inside the house or indoors without having to go outside. In addition, the user can check the delivery status in real time through a mobile terminal (500) and perform additional operations (e.g., reservation of receipt, extension of storage time, etc.) if necessary.

[0110] Afterward, the lid (111) of the smart container is closed under the control of the drive unit (140), and the container is kept in a sealed state. During this process, a sealed structure designed to prevent external environmental factors (e.g., wind, rain, dust, etc.) from penetrating into the interior is applied.

[0111] FIG. 11 is a flowchart illustrating a process for determining the order of receiving goods and controlling the approach of drones according to the determined order when multiple drones approach simultaneously in the drone delivery receiving system (100) of the present invention.

[0112] The control unit (130) of the drone delivery receiving system (100) can detect a situation in which multiple drones approach simultaneously (step S610). Each drone transmits an approach request signal to the control unit (130) via wireless communication, and the control unit (130) receives status information of each drone and starts a process.

[0113] The control unit (130) can determine the order of receiving items for each drone based on the status information transmitted by the multiple drones (step S620). The order of receiving items can be determined according to the calculation result of the receiving priority described later.

[0114] For example, the case where drones A, B, C, and D approach simultaneously is explained. The control unit (130) can receive status information of each drone and calculate the reception priority.

[0115] The order of receiving items can be determined based on the importance of the delivered items (whether they are general goods or fresh food), the battery status of the drone (whether the battery is above a threshold or below a threshold), and the priority (high, medium, low) preset by the user. Items with a higher priority are received first, and the priority of receipt can be determined according to [Equation 1] below.

[0116] [Mathematical Formula 1]

[0117]

[0118] Here, a, b, and c are weights of each item and can be preset by the administrator. In one embodiment, a can be set to 0.3, b to 0.2, and c to 0.5. The importance of the delivery item can be set to 0.5 for general items and 1 for fresh food. The drone's battery status can be set to 0.5 if it is above a threshold and 1 if it is below a threshold. The preset priority can be set to 0.1 for "low," 0.5 for "medium," and 1 for "high."

[0119] [Drone Status Information and Receipt Priority Calculation]

[0120] (1) Drone A

[0121] - Delivery Item Importance: General Item (0.5)

[0122] -Battery status: Above threshold (0.5)

[0123] - Preset priority: Medium (0.5)

[0124] - Receipt Priority = 0.3 * 0.5 + 0.2 * 0.5 + 0.5 * 0.5 = 0.15 + 0.1 + 0.25 = 0.5

[0125] (2) Drone B

[0126] -Importance of delivery items: Fresh food (1)

[0127] -Battery status: Above threshold (0.5)

[0128] - Preset priority: High (1)

[0129] - Receipt Priority = 0.3 * 1 + 0.2 * 0.5 + 0.5 * 1 = 0.3 + 0.1 + 0.5 = 0.9

[0130] (3) Drone C

[0131] - Delivery Item Importance: General Item (0.5)

[0132] -Battery status: Below threshold (1)

[0133] - Preset priority: Medium (0.5)

[0134] - Receipt Priority = 0.3 * 0.5 + 0.2 * 1 + 0.5 * 0.5 = 0.15 + 0.2 + 0.25 = 0.6

[0135] (4) Drone D

[0136] - Delivery Item Importance: General Item (0.5)

[0137] -Battery status: Above threshold (0.5)

[0138] - Preset priority: Low (0.1)

[0139] - Receipt Priority = 0.3 * 0.5 + 0.2 * 0.5 + 0.5 * 0.1 = 0.15 + 0.1 + 0.05 = 0.3

[0140] (5) Final order determination

[0141] Drone B (0.9) > Drone C (0.6) > Drone A (0.5) > Drone D (0.3)

[0142] In the case of Drone A, it is transporting general goods, its battery status is above a threshold, and its priority is set to medium. Based on this, the calculated receiving priority is 0.5. Drone B is transporting fresh food, has a good battery status, and its priority is set to high, so its receiving priority is the highest at 0.9. Drone C is transporting general goods, but its battery status is below a threshold and its priority is set to medium, so its receiving priority is evaluated as 0.6. Finally, Drone D is transporting general goods and has a good battery status, but its priority is set to low, so its receiving priority is the lowest at 0.3.

[0143] The control unit can transmit a control signal for the approach order to the drones based on the calculated reception priority and control the approach of multiple drones (step S630).

[0144] The control unit (130) transmits a control signal to allow drone B to approach first based on the calculated receiving priority, and then to allow drones C, A, and D to receive the goods in that order. Each drone receives an approach signal from the control unit (130) in order and approaches the smart container (110) in the designated order to deliver the goods.

[0145] FIG. 12 is a flowchart illustrating the procedure for handling additional items delivered via drone in the drone delivery receiving system (100) of the present invention when there are items already stored in the smart container (110). Each step is described below.

[0146] [Detection of additional drone approach while items are in storage (Step S710)]

[0147] The control unit (130) of the smart container (110) detects a situation in which a drone approaches additionally. For example, a drone carrying fresh food may approach while general goods are already stored in the smart container (110). The control unit (130) receives the drone's approach signal and initiates a procedure to determine whether to receive additional goods.

[0148] [Determination of eligibility for receiving additional items (Step S720)]

[0149] The control unit (130) checks how many items are currently stored inside the container (110) and determines whether there is space to store additional items. For example, if the maximum item capacity of the smart container (110) is 2 and 2 items are already stored, new items may or may not be stored depending on their size or shape.

[0150] At this stage, a loading status detection sensor mounted on the smart container (110) provides internal space information, and the control unit (130) can determine whether additional items can be received based on this information.

[0151] [Request user approval if additional items cannot be received (Step S730)]

[0152] If it is determined that there is insufficient space to store additional items inside the container (110), the control unit (130) sends a notification to the user terminal device (500) and sends a request for approval for the operation of receiving new items after discharging the items currently being stored.

[0153] For example, if the user determines that there is no problem with discharging items already in storage, they may approve a request to discharge the current items and receive fresh food through the application of the terminal device (500). Conversely, if the user determines that there may be a problem when discharging items in storage (for example, if there is a high risk that the items in storage will be damaged upon discharge), the user may refuse to receive additional items or select a different delivery option.

[0154] [Proceed with receipt of additional items upon user approval (S740)]

[0155] When the user transmits an approval response from the terminal device (500), the control unit (130) controls the drive unit (140) to proceed with the discharge of stored items and the receipt of additional items. For example, if the user approves to discharge general items currently in storage first, the lid (111) of the container (110) is opened and the stored items can be discharged into a space such as a veranda. Subsequently, an additionally approaching drone safely places fresh food into the container (110).

[0156] During this process, multiple drones can be controlled so that the approach order and movements between the drones are coordinated to prevent confusion. Once all procedures are completed, the smart container (110) can be switched back to a standby state.
