DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A delivery storage system according to an embodiment of the present invention will be described below. EXAMPLES

[0015] A delivery storage system according to a first embodiment will be described with reference to Fig. 1 to Fig. 7. The delivery storage system in this embodiment is a system that, when a delivery person visits a resident while the resident is absent, causes the resident to place the delivery in a home delivery box, thereby preventing redelivery.

[0016] As shown in FIG. 1, the delivery storage system 1 is composed of a delivery box 2 installed at the entrance of a residence such as a detached house or an apartment building, an intercom 3 installed in the residence, a mobile communication terminal 4 carried by the resident who is the user of the delivery box 2 and intercom 3, and a server 5 that provides services for the delivery storage system 1.

[0017] The server 5 is connected to the Internet and includes a correspondence management means capable of linking and managing a unique user ID set for each resident who is a user of the service provided by the provider, a unique box ID set for the delivery box 2 used by the resident, a unique ID set for the intercom 3 used by the resident (terminal ID of the gateway terminal 8 described later), and a unique mobile ID set for the mobile communication terminal 4 carried by the resident. The server 5 also includes a calculation means.

[0018] The intercom 3 is composed of an outdoor unit 6, an indoor unit 7, and a gateway terminal 8. As shown in Fig. 2, the outdoor unit 6 is fixed near the front door or on the gate, and is equipped with an imaging means 9, a microphone 10, a speaker 11, a call button 12, and a delivery button 13. The call button 12 and the delivery button 13 form a visitor notification button that can be pressed by a visitor. The outdoor unit 6 is also connected to the indoor unit 7 by wire so as to be able to communicate with it, and is also connected to the gateway terminal 8 and the delivery box 2 by wireless communication such as Wi-Fi so as to be able to communicate with it.

[0019] As shown in Fig. 3, the indoor unit 7 is equipped with a display screen 14, a microphone 15, a speaker 16, a call button 17, an end button 18, and an answering machine setting button 19. Although this is a widely used technology and will not be described in detail here, when the call button 12 of the outdoor unit 6 is pressed, a ring tone is played from the speaker 16 of the indoor unit 7. Also, by pressing the call button 17, a call can be made using the speakers 11, 16 and microphones 10, 15 of both units. In addition, an image of a person standing in front can be viewed on the display screen 14 of the indoor unit 7 by the imaging means 9 of the outdoor unit 6.

[0020] As shown in FIG. 4, the gateway terminal 8 includes a wireless communication means 20, an Internet communication means 21, and an MPU 22 built therein.

[0021] As shown in Fig. 5, delivery box 2 is a hexahedron made of metal plates or the like, one of which is open, and opening 2a can be opened and closed by opening door 25. Opening door 25 is provided with locking means 26. Locking means 26 is a numeric keypad that can physically lock the locking mechanism from the outside, and also has driving means (not shown) for driving the locking mechanism. Delivery box 2 also has wireless communication means and a power source (not shown), and is capable of communicating with outdoor unit 6 via the wireless communication means.

[0022] Furthermore, the interior space of the delivery box 2 is divided into upper and lower spaces by a shelf 29. Sensors 28A and 28B (delivery detection means), which are strain gauges, are installed in the divided spaces 27A and 27B, respectively, to detect the contents. The detection information of these sensors 28A and 28B can be transmitted to the outdoor unit 6 by wireless communication means. In this embodiment, the upper divided space 27A has a capacity to hold 60-size deliveries, and the lower divided space 27B has a capacity to hold 80-size deliveries.

[0023] A specific application is installed on the mobile communication terminal 4 owned by a resident who is a user of the service provided by the provider. When using the application, a user ID and password are set in advance. The set user ID and password are sent to the server 5 via the cellular line of the mobile communication terminal 4 or the Internet via wireless communication such as Wi-Fi, together with a mobile ID used in a signaling protocol such as SIP, and are managed by the correspondence management means.

[0024] In the server 5, a correspondence management means manages a mobile ID, a terminal ID of the gateway terminal 8 which is a communication device, and a box ID of the delivery box in association with the user ID. In the application, a screen (not shown) is displayed prompting the user to enter a user ID and a password, and the entered user ID and password are sent to the server 5 for authentication.

[0025] If the user ID and password received from the mobile communication terminal 4 via the application are correct, the server 5 has the function of identifying the IP address of the corresponding gateway terminal 8 using a signaling protocol and enabling mutual communication between the gateway terminal 8 and the mobile communication terminal 4 running the application.

[0026] Next, the functions of the delivery storage system that can be used by a resident who is a user of the service provided by the provider when he / she is out will be explained with reference to Figs. 6 and 7, assuming a case where a delivery person actually visits. When going out, the resident starts an application on the mobile communication terminal 4 in advance and changes to away mode. A notification of the change to away mode is sent to the server 5 together with identification information (user ID or mobile ID, terminal ID of the gateway terminal 8, box ID, or a combination thereof) that identifies the resident or the resident's house. Based on the change notification, the server 5 sends an instruction to start away mode via the Internet to the outdoor unit 6 of the corresponding resident's house. The resident can also start and end away mode by pressing the away setting button 19 (see Fig. 3) on the indoor unit 7.

[0027] 2, the delivery button 13 is a button dedicated to the delivery person's response, and is marked with a picture of a cardboard box containing the delivery so that it can be distinguished at a glance from a normal call button. When the delivery button 13 is pressed, the outdoor unit 6 notifies the server 5 via the gateway terminal 8 that a delivery person has arrived (notification function).

[0028] The server 5 processes the visit notification for the mobile communication terminal 4 based on the identification information of the sender of the visit notification (notification function). In detail, the server 5 refers to the information managed by the correspondence management means, and identifies, by a signaling protocol, the IP address of the mobile communication terminal 4 that corresponds to the terminal ID of the gateway terminal 8 to which the outdoor unit 6 that is the sender of the visit notification is connected, and makes the gateway terminal 8 (and the outdoor unit 6) and the mobile communication terminal 4 capable of communicating with each other via the Internet using the IP address.

[0029] The outdoor unit 6 sends a call notification to the mobile communication terminal 4. Call notifications are common and will not be described in detail here, but they are a ringtone or push notification sent by running an application in the background. When the resident responds to the call notification by tapping or the like, the application is started and a call is established between the outdoor unit 6 and the mobile communication terminal 4. This call state is, for example, a call state using VoIP (Voice over Internet Protocol), and in addition to the audio conversation, the image captured by the imaging means 9 of the outdoor unit 6 can be viewed on the mobile communication terminal 4 (see FIG. 7).

[0030] As shown in FIG. 7, the call screen 30 of the mobile communication terminal 4 displays, in addition to an image display 31 that displays an image captured by the imaging means 9 of the outdoor unit 6, a lock button 32 that can be used to send an instruction to lock the locking means 26, and an unlock button 33 that can be used to send an instruction to unlock it, so that locking and unlocking can be performed from the mobile communication terminal 4 side as necessary (unlocking operation means), and in addition, the color of one of the lock button 32 and unlock button 33 can be highlighted, making it possible to distinguish whether the state is locked or unlocked at that time.

[0031] Additionally, an availability indicator 34 showing the availability of the delivery box 2 at that time is displayed on the call screen 30. The availability indicator 34 displays whether or not cargo can be placed in the divided spaces 27A, 27B, based on the received detection information by the sensors 28A, 28B.

[0032] The resident talks to the delivery person to find out the size of the delivered item B. The resident then gives appropriate instructions to the delivery person by referring to the availability display 34. For example, if the availability display 34 indicates that a delivery item is in the upper divided space 27A and that it is possible to place the item in the lower divided space 27B, and the delivered item B is a size 60, the resident verbally instructs the delivery person to place the item in the lower divided space 27B of the home delivery box 2, since the lower divided space 27B can accommodate items up to a size 80.

[0033] In the state of Fig. 7, a delivery has been placed in the upper divided space 27A, i.e., another delivery person has locked the delivery box 2 after placing the delivery. This can be determined from the fact that the lock button 32 is highlighted on the call screen 30. Therefore, the resident taps the unlock button 33 to unlock the locking means 26, making it possible to place a delivery into the lower divided space 27B of the delivery box 2 (unlock operation means).

[0034] More specifically, when the unlock button 33 is pressed, an unlock instruction is sent from the mobile communication terminal 4 to the server 5, and the server 5 transmits the unlock instruction to the corresponding outdoor unit 6. This transmission of the unlock instruction is performed without using a signaling protocol, etc., because the mobile communication terminal 4 and the outdoor unit 6 are already in a state where they can communicate with each other.

[0035] The outdoor unit 6, which has received the unlock instruction, issues an unlock instruction to the delivery box 2 using wireless communication means. In accordance with the unlock instruction, the delivery box 2 unlocks the locking means 26 by driving the driving means. The delivery person locks the delivery box 2 after placing the package in the lower partition space 27B as instructed, and reports the completion of the delivery work by phone.

[0036] Furthermore, when loading of the lower divided space 27B is performed, the sensor 28B detects the delivery B, and transmits the detection information to the server 5. The server 5 updates in real time the portion of the lower divided space 27B in the availability status display 34 on the call screen 30 to a display indicating that loading is unavailable.

[0037] In this way, in the delivery storage system 1 in this embodiment, the outdoor unit 6 constituting the intercom 3 has a notification function that can send a visitor notification (specific notification) to the mobile communication terminal 4 via the Internet when the delivery button 13 that notifies the resident of a visit is pressed, and the mobile communication terminal 4 has an unlocking operation means that can unlock the locking means 26 of the opening and closing door 25 of the delivery box 2 via the Internet. According to this, when the delivery button 13 is pressed by the delivery person, a visitor notification is sent to the mobile communication terminal 4 of the resident, and the resident can know the delivery person's visit. In addition, the resident can unlock the locking means 26 of the delivery box 2 as needed from outside the home via the Internet. Therefore, even if the resident forgets to unlock the door before going out or is unable to unlock the door because they are not aware that a delivery is scheduled, by remotely unlocking the door in time with the delivery person's visit, the delivery person can open the opening and closing door 25 and reliably put in the delivery B, and redelivery can be prevented.

[0038] In addition, the unlock button 33 as the unlocking operation means is operably displayed on the call screen 30 between the outdoor unit 6 and the mobile communication terminal 4, so the resident can confirm during the call that the remote unlocking of the locking means 26 has been completed, and can reliably guide the resident to place the delivery B in the home delivery box 2 without hanging up the phone.

[0039] In addition, residents can check the availability of the delivery box 2 using the availability display 34 displayed on the mobile communication terminal 4, so they can guide the delivery person to place the parcel in the delivery box 2 based on accurate information.

[0040] Furthermore, when a delivery is placed in divided spaces 27A, 27B, sensors 28A, 28B detect the delivery and transmit the detection information to server 5, which then updates in real time the availability display 34 on the call screen 30. This allows the resident to accurately check the availability of delivery box 2 in real time, and based on the accurate information, can guide the delivery person to place the delivery in delivery box 2, while also being able to confirm the completion of placement. EXAMPLES

[0041] Next, a delivery storage system according to a second embodiment will be described with reference to Figures 8 and 9. Note that the same components as those shown in the above embodiment will be denoted by the same reference numerals and duplicated explanations will be omitted.

[0042] 8, delivery box 42 in the second embodiment has no internal partitions and has one large luggage compartment.

[0043] As shown in Fig. 9, the call screen 40 of the mobile communication terminal 4 displays the video display 31, the lock button 32, the unlock button 33, and the availability display 45. Detection information from the height detection sensor 44 (delivery detection means) of the delivery box 2 is sent to the outdoor unit 6. The calculation unit A (see Fig. 2) of the outdoor unit 6 calculates the availability from the received detection information related to height, in this case, how much space is available in the vertical direction, in other words, what size of cardboard box of a general shape (including some degree of error) is available for loading. As a result, the available size is displayed on the availability display 45.

[0044] The resident talks to the delivery person and finds out the size of the delivered item B. The resident then refers to the availability display 45 and gives the delivery person appropriate instructions while unlocking the door. For example, if a 60-size item is already inside the door and there is space above the 60-size item to fit an 80-size item, the availability display 45 will show that an 80-size item can be accommodated, and if there is no item inside the door, the availability display 45 will show that there is space available to fit a 120-size item.

[0045] In this way, no partitions are provided in the delivery box 42, and the delivery box 42 itself detects changes in the available capacity, determines the available size of the cargo, and displays the available size to the mobile communication terminal 4. This allows for flexible loading of various sizes of cargo, and there is no limit to the number of cargoes that can be loaded until the available capacity is reached, effectively preventing the need for redelivery. EXAMPLES

[0046] Next, a delivery storage system according to a third embodiment will be described with reference to Figures 10 and 11. Note that the same components as those shown in the above embodiment will be denoted by the same reference numerals and duplicated explanations will be omitted.

[0047] The outdoor unit 46 is equipped with a distance measuring means. The distance measuring means is capable of three-dimensionally measuring an object by irradiating a laser beam or the like in a pulsed manner and measuring the time it takes for the beam to be received, and is composed of a module section 47 consisting of an irradiating section and a light receiving section, which is installed near the imaging means 9, and a calculation section A built into the outdoor unit 46, as shown in FIG.

[0048] The distance measuring means can measure the three-dimensional dimensions of a delivery placed within a predetermined angle of view and a predetermined distance in front of the outdoor unit 46. The calculation unit A can then determine which size of a commonly shaped cardboard box it corresponds to.

[0049] The outdoor unit 46 further calculates the available space for a cardboard box of a certain size based on the detection information from the height detection sensor 44 of the delivery box 42 (see FIG. 8), and determines whether the delivery item B brought by the delivery person is of a size that can be placed in the delivery box 42 at that time (determination process). As shown in FIG. 11, the result of this determination process is displayed on the call screen 50 of the mobile communication terminal 4 as a possibility indicator 51 indicating whether the item can be placed. The resident refers to this possibility indicator 51 to give appropriate instructions to the delivery person and performs the unlocking operation.

[0050] In this way, the distance measuring means of the outdoor unit 46 measures the three-dimensional dimensions of the delivery item, the delivery box 42 itself detects changes in the available space, and a decision is made as to whether or not the delivery item B brought by the delivery person can be placed in the delivery box 42 at that time, all without the intervention of judgment from the delivery person or the resident, thereby preventing the occurrence of human error and enabling the delivery work to be completed quickly.

[0051] 11(a), a measurement start button 52 is displayed on the call screen 50, and when this measurement start button 52 is tapped, the outdoor unit 46 starts the delivery measurement process and guides the delivery person through the speaker 11 on the procedure. For example, voice announcements such as holding the delivery B in front of the outdoor unit 46, "Please move the delivery away", "Please lift the delivery", and "Please hold all six sides in order" are also made as necessary to accurately measure the three-dimensional dimensions.

[0052] Also, as shown in FIG. 11(b), if delivery item B is too large for the available space in the delivery box and cannot be placed in it, the availability indicator 51 will show that it cannot be placed in, in which case the resident can take measures such as having the delivery person place the item on the floor in a specified location.

[0053] Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention also includes modifications and additions that do not deviate from the gist of the present invention.

[0054] For example, in the above embodiment, the unlocking instruction from the mobile communication terminal 4 is sent to the gateway terminal 8 via the Internet, relayed through the outdoor unit 6 connected to the gateway terminal 8 via a local network, and then sent to the delivery box 2 connected to the outdoor unit 6 via the local network. However, this is not limited to the above, and for example, the outdoor unit 6 may be directly connectable to the Internet, or the delivery box 2 may be directly connectable to the Internet.

[0055] In addition, in the above embodiment, when the away mode is initiated, pressing the delivery button 13 (visitor notification button) causes the outdoor unit 6 to attempt communication between the delivery person and the mobile communication terminal 4. However, the present invention is not limited to this. For example, if there is no response from the indoor unit 7 until a preset time has elapsed after pressing the call button 12 (visitor notification button), the outdoor unit 6 may determine that the person is not at home and automatically attempt communication between the delivery person and the mobile communication terminal 4.

[0056] Furthermore, the delivery detection means provided in the delivery box 2 is not limited to strain gauges such as the sensors 28A and 28B in the first embodiment, but may be, for example, an infrared sensor or a weight sensor. Similarly, the delivery detection means is not limited to the height detection sensor 44 in the second embodiment, but may be, for example, a distance measuring means similar to that provided in the outdoor unit 46 in the third embodiment.

[0057] In addition, in the above-mentioned second embodiment, the calculation unit A of the outdoor unit 6 is configured to convert the internal free space into the standard delivery size that can be loaded based on the detection information from the height detection sensor 44 and display it on the call screen 40, but this is not limited to the above. For example, the free space may be displayed as an image of a three-dimensional shape, or the three-dimensional dimensions of the space of the free space may be displayed.

[0058] In addition, in the above-mentioned Example 3, the calculation unit A of the outdoor unit 6 is configured to determine whether or not a cargo can be loaded by comparing the internal free space with the three-dimensional dimensions of the cargo measured by the distance measuring means based on the detection information from the height detection sensor 44, but this is not limited to the above, and for example, the three-dimensional dimensions of the free space may be directly compared with the three-dimensional dimensions of the cargo to determine whether or not a cargo can be loaded.

[0059] In addition, when the delivery button 13 is pressed, the outdoor unit 6 notifies the mobile communication terminal 4 of the arrival of a delivery person, but the specific notification provided by this notification function is not limited to a notification of a visit and may be, for example, a notification simply prompting the user to unlock the locking means 26 of the opening and closing door 25.

[0060] Needless to say, the delivery storage system of the present invention can be used without installing a delivery box and only for delivery to a designated place, but it can also accommodate a service of delivering packages to the inside of a house. In this case, the outdoor unit is configured to communicate with the locking device of the front door and unlock it when an unlocking operation is performed from the mobile communication terminal 4. In this case, it is preferable to install a surveillance camera or the like inside the house from the viewpoint of security and record and manage the video by matching the time axis with the video captured by the imaging means of the outdoor unit.
