[0018] The embodiments of the management system and management program according to this invention will be described in detail below with reference to the attached drawings. First, the basic concept of Embodiment [I] will be explained, then the specific details of Embodiment [II] will be explained, and finally, modifications of Embodiment [III] will be explained. However, the present invention is not limited by the embodiments.

[0019] [I] Basic Concepts of the Embodiments First, the basic concepts of the embodiment will be explained. The embodiment relates to a management system and a management program. The management system according to the present invention is a system for managing target equipment to be unlocked or locked.

[0020] "Target equipment" refers to equipment managed by the management system, and is a concept that includes, for example, materials and equipment used at construction sites or any other items. "Materials and equipment" is a concept that includes, for example, aerial work platforms, forklifts, scaffolding, or elevators.

[0021] In the embodiments described below, we will explain the case where the "target equipment" is an aerial work platform as a piece of equipment.

[0022] [II] Specific details of the embodiment Next, the specific details of the embodiment will be described.

[0023] (composition) First, the management system according to this embodiment will be described. Figure 1 is a diagram showing the management system according to this embodiment, and Figure 2 is a block diagram showing the management system functionally. The number of each element included in the management system 100 is arbitrary, but in this embodiment, the elements shown will be described. Also, the shape and mounting position of the key management device 3 in Figure 1 are illustrated for the convenience of explanation.

[0024] The management system 100 shown in Figures 1 and 2 is a system for managing the aerial work platform 4 and includes, for example, a terminal device 1, a server device 2, and a key management device 3.

[0025] (Configuration - Aerial work platform) The aerial work platform 4 is the aforementioned equipment (i.e., the target device), and is, for example, a device used at construction sites. This aerial work platform 4 can be configured with a known configuration, such as a motor and battery, so only a brief description will be given. The aerial work platform 4 includes, for example, the work platform 41 and the operating unit 42 shown in Figure 1.

[0026] (Configuration - Aerial work platform - Work platform) The work platform 41 is, for example, designed to allow workers to perform tasks at relatively high altitudes, and is configured to rise or fall with workers on it.

[0027] (Configuration - Aerial work platform - Control unit) Figure 3 is a front view of the control panel. The control panel 42 in Figures 1 to 3 is an operating means for switching the operating mode of the aerial work platform 4, and is operated by the user to switch between the first mode and the second mode.

[0028] "Operation mode" refers to a mode for operating the aerial work platform, and is a concept that includes, for example, a first mode and a second mode. "First mode" is a mode in which a predetermined operation of the aerial work platform 4 is possible, and in this embodiment, for example, is a concept that indicates the upper operation mode described later. "Second mode" is a mode in which a predetermined operation of the aerial work platform 4 is impossible, and in this embodiment, for example, is a concept that indicates the lower operation mode and the OFF mode described later.

[0029] The aerial work platform 4 is configured to move itself horizontally (hereinafter also referred to as "horizontal movement") by driving its wheels, or to move the work platform 41 vertically (hereinafter also referred to as "vertical movement"). This "horizontal movement" is a horizontal movement of the aerial work platform 4, and is therefore also referred to as "horizontal movement." Similarly, "vertical movement" is a vertical movement of the aerial work platform 4, and is therefore also referred to as "vertical movement." In this embodiment, we will describe the case in which the horizontal movement corresponds to a "predetermined movement."

[0030] The operating unit 42 includes, for example, a knob 421, as shown in Figure 3. The knob 421 is a component that can rotate around a pivot axis (an axis shown as a point conveniently drawn at the center of the knob 421 in each figure of Figure 3) by receiving rotational force from the user. The knob 421 can rotate to the "upper operation" position (Figure 3(a)) for setting the aerial work platform 4 to upper operation mode, the "OFF" position (Figure 3(b)) for setting the aerial work platform 4 to OFF mode, or the "lower operation" position (Figure 3(c)) for setting the aerial work platform 4 to lower operation mode.

[0031] The "upper operation mode" is the first mode mentioned above, and specifically, it is a mode that enables horizontal and vertical movement. For example, it is a mode that allows the aerial work platform 4 to move both horizontally and vertically (i.e., a mode that enables a predetermined horizontal movement). When set to upper operation mode, the aerial work platform 4 moves horizontally by operating the horizontal movement pedal (not shown), and the work platform 41 of the aerial work platform 4 moves vertically by operating the vertical movement lever or vertical movement button (not shown).

[0032] The "lower operation mode" is the second mode mentioned above, and specifically, it is a mode that enables vertical movement. For example, it is a mode that allows only vertical movement of the aerial work platform 4 (i.e., a mode in which a predetermined horizontal movement is impossible). When set to lower operation mode, even if the horizontal movement pedal (not shown) is operated, the aerial work platform 4 will not move horizontally. Instead, the work platform 41 of the aerial work platform 4 will move vertically by operating the vertical movement lever or vertical movement button (not shown).

[0033] The "OFF mode" is the second mode mentioned above, and specifically, it is a mode in which horizontal and vertical movement is impossible. For example, it is a mode that makes it impossible for the aerial work platform 4 to move both horizontally and vertically (i.e., a mode in which a predetermined horizontal movement is impossible). When set to OFF mode, even if the horizontal movement pedal (not shown) is operated, the aerial work platform 4 will not move horizontally, and even if the vertical movement lever or vertical movement button (not shown) is operated, the work platform 41 of the aerial work platform 4 will not move vertically.

[0034] (Configuration - Terminal device) The terminal device 1 in Figures 1 and 2 is a device carried by the user and communicates with, for example, the server device 2 and the aerial work platform 4 (specifically, the key management device 3 installed on the aerial work platform 4). One example of such a device is a tablet terminal or a smartphone.

[0035] As shown in Figure 2, the terminal device 1 includes, for example, a communication unit 11, a touchpad 12, a display 13, a recording unit 14, and a control unit 15.

[0036] (Configuration - Terminal Equipment - Communication Unit) The communication unit 11 in Figure 2 is a communication means for communicating with other devices (server device 2 and key management device 3). The specific configuration of this communication unit 11 is arbitrary, but for example, it can be configured with a known wireless communication circuit.

[0037] In this embodiment, the communication unit 11 is configured to perform wireless communication with the key management device 3 based on a communication standard compatible with Bluetooth® (for example, wireless communication that can communicate within an effective range of a predetermined distance such as approximately 10m to 15m), but the embodiment is not limited to this configuration.

[0038] (Configuration - Terminal device - Touchpad) The touchpad 12 in Figure 2 is an operating means that receives various operation inputs from the user when pressed by the user's finger or the like. The specific configuration of this touchpad 12 is arbitrary, but for example, a known one equipped with an operation position detection means such as a resistive type or a capacitive type can be used.

[0039] (Configuration - Terminal device - Display) The display 13 in Figure 2 is an image display means that displays various images based on the control of the control unit 15. The specific configuration of this display 13 is arbitrary, but for example, a known liquid crystal display or an organic EL display or other flat panel display can be used. The touch pad 12 and the display 13 may also be integrally formed as a touch panel.

[0040] (Configuration - Terminal device - Recording unit) The recording unit 14 in Figure 2 is a recording means for recording programs and various data necessary for the operation of the terminal device 1, and is configured, for example, using flash memory (not shown) as an external recording device. However, any other recording medium can be used instead of or in conjunction with flash memory, including magnetic recording media such as hard disks and magnetic disks, or optical recording media such as DVDs and Blu-ray discs (the same applies to the recording units of other devices).

[0041] The recording unit 14 is, for example, a key information storage means for storing key information (Figure 2). "Key information" refers to information for unlocking the aerial work platform 4, and its specific contents will be described later.

[0042] (Configuration - Terminal device - Control unit) The control unit 15 in Figure 2 is a control means for controlling the terminal device 1, and is specifically a computer comprising a CPU, various programs interpreted and executed on the CPU (including basic control programs such as an OS, and application programs launched on the OS to realize specific functions), and internal memory such as RAM for storing programs and various data. In particular, the program according to this embodiment is installed on the terminal device 1 via any recording medium or network, and substantially constitutes each part of the control unit 15 (the same applies to the control units of other devices).

[0043] The control unit 15 functions, for example, as an unlocking means. The processing performed by such a control unit 15 will be described later.

[0044] The unlocking means is, for example, a means for performing unlocking-related processing to unlock the target equipment in one of a plurality of unlocking modes that define matters concerning the locking of the aerial work platform 4 at the time of unlocking. The unlocking means is also a means for performing unlocking-related processing to unlock the aerial work platform 4 based on key information transmitted by the server device 2. The unlocking means is also a means for performing the process of transmitting key information stored in the recording unit 14 to the aerial work platform 4 side (in this embodiment, the key management device 3 provided on the aerial work platform 4) as an unlocking-related processing.

[0045] In this embodiment, for example, a case in which a first unlocking mode and a second unlocking mode are provided as "multiple unlocking modes" will be described, and variations will be described in the modified examples. The "first unlocking mode" is a mode in which the aerial work platform 4 is locked after being unlocked, for example, a mode in which it is locked when predetermined conditions are met after unlocking, and in this embodiment, it is a mode in which a locking process (described later) is performed after unlocking. The "second unlocking mode" is a mode in which the aerial work platform 4 is not locked after being unlocked, and in this embodiment, it is a mode in which a locking process (described later) is not performed after unlocking.

[0046] (Configuration - Server Equipment) The server device 2 in Figures 1 and 2 is, for example, a device that communicates with the terminal device 1. One example of this configuration is a server computer located in any location such as a data center, or a so-called cloud computer realized by multiple computers.

[0047] As shown in Figure 2, the server device 2 includes, for example, a communication unit 21, a recording unit 22, and a control unit 23.

[0048] (Configuration - Server device - Communications unit) The communication unit 21 in Figure 2 is a communication means for communicating with other devices (terminal device 1). The specific configuration of this communication unit 21 is arbitrary, but for example, it can be configured with a known wireless communication circuit or the like.

[0049] (Configuration - Server device - Recording unit) The recording unit 22 in Figure 2 is a storage means for storing programs and various data necessary for the operation of the server device 2. This recording unit 22 also includes, for example, a user-related information database 221 (hereinafter, the database is referred to as "DB"), equipment-related information DB 222, and reservation / key-related information DB 223.

[0050] (Configuration - Server device - Recording unit - User-related information DB) The user-related information DB221 in Figure 2 is a user-related information storage means for storing user-related information.

[0051] Figure 4 is an example of user-related information. "User-related information" refers to information about the user who will be using the aerial work platform 4, and for example, the information of each item shown in Figure 4 is interconnected.

[0052] The "User ID" field contains user identification information that uniquely identifies a user (the identification information is also referred to as "ID") (e.g., "UID0001" in Figure 4). The "Name Information" field contains name information indicating the user's name (e.g., "AAA1" in Figure 4). Note that "AAA1" etc. is used for explanatory purposes and represents a name. The "Company Information" field contains company information indicating the company (i.e., organization) to which the user belongs (e.g., "A Construction" in Figure 4, which is the name of a cooperating company).

[0053] For example, the information at the top of Figure 4 indicates that the user identified by "UID0001" is named "AAA1," and that the company to which this user belongs is "A Construction."

[0054] The method for storing such user-related information is arbitrary, but for example, the information may be stored by inputting it to server device 2.

[0055] (Configuration - Server device - Recording unit - Equipment-related information database) The equipment-related information DB222 in Figure 2 is an equipment-related information storage means for storing equipment-related information.

[0056] Figure 5 is an example of equipment-related information. "Equipment-related information" refers to information about the equipment, specifically the aerial work platform 4. For example, the information for each item shown in Figure 5 is interconnected.

[0057] The "Equipment ID" field contains the equipment ID that uniquely identifies the aerial work platform 4 (in Figure 5, this is represented by "EID0001" to "EID0003," etc., indicating aerial work platforms 401 to 403 in Figure 1). The "Name Information" field contains the name information of the aerial work platform 4 (in Figure 5, this is represented by "Unit 1," etc.). The "Type Information" field contains the type information of the aerial work platform 4 (in Figure 5, this is represented by "9m Aerial Work Platform," etc.).

[0058] The item "Return Information" in Figure 5 is return information relating to the return of the aerial work platform 4. In this embodiment, for example, a general contractor for a construction project rents the aerial work platform 4 from a rental company (a company that rents out the aerial work platform 4) and allows its use at the construction site on a per-subcontractor basis (i.e., on a per-subcontractor basis such as "A Construction"). Furthermore, the subcontractors reserve and use the aerial work platform 4 that the general contractor has rented from the rental company. In addition, when the general contractor returns the aerial work platform 4 that it has rented to the rental company, it performs a return process for the aerial work platform 4 being returned.

[0059] "Return processing" refers to the process of returning the aerial work platform 4 to the rental company, for example, by removing it from the list of candidates for reservation by a cooperating company. In this embodiment, for example, a user of the main contractor company can select the aerial work platform 4 to be returned via their own computer (for example, terminal device 1, etc.) and perform a return operation (for example, by pressing the return button in the application that manages the aerial work platform 4), thereby making the aerial work platform 4 subject to return, and preventing cooperating companies from reserving and using it after that operation.

[0060] The return information in Figure 5 stores information related to this return operation. For example, it stores "Not yet returned" to indicate that the return operation has not yet been performed (i.e., that the item is not yet subject to return to the rental company), and "Returned (2022 / 2 / 27)" to indicate that the return operation was performed on February 27, 2022.

[0061] For example, the information at the top of Figure 5 indicates that the aerial work platform 401 identified by "EID0001" is named "Unit 1" and is of the type "9m aerial work platform". It also indicates that the return operation for this aerial work platform 401 has not yet been carried out.

[0062] The method for storing such equipment-related information is arbitrary, but for example, the equipment ID, name information, and type information may be stored by the general contractor when they rent the aerial work platform 4 and input the information into the server device 2. In addition, for return information, "Not yet returned" may be stored as initial information, and when the aforementioned return operation is performed, information such as "Returned (2022 / 2 / 27)" may be stored.

[0063] (Configuration - Server device - Recording unit - Reservation / key-related information database) The reservation / key-related information DB223 in Figure 2 is a reservation / key-related information storage means for storing reservation / key-related information.

[0064] Figure 6 is an example of reservation and key-related information. "Reservation and key-related information" refers to information regarding the usage reservation status and key information, and for example, the information of each item shown in Figure 6 is interconnected. "Usage reservation status information" refers to information indicating the usage reservation status of the aerial work platform 4.

[0065] The information for the item "Equipment ID" in Figure 6 is the same as the information with the same name in Figure 5. The "Reservation Date and Time Information" in Figure 6 is reservation time information indicating the reserved time slot for the aerial work platform 4, and in particular, reservation date and time information indicating the reservation date and time slot. In Figure 6, the day is divided into a morning time slot and an afternoon time slot, and the morning and afternoon are used as the time slots, and the case where "0301-AM" indicates the morning time slot on March 1st, "0301-PM" indicates the afternoon time slot on March 1st, etc. is explained. The information corresponding to the item "Reservation Company Information" in Figure 6 is reservation company information indicating the company that has reserved the aerial work platform 4 (in Figure 6, "A Construction", etc.).

[0066] The item "Key Acquisition User Information" in Figure 6 is the key acquisition user information that indicates the user who acquired and stored the key information on their own terminal device 1 (i.e., downloaded it to terminal device 1). In this embodiment, for example, we will describe a case where a user downloads key information to unlock a high-altitude work vehicle 4 reserved by the company to which they belong from the server device 2, and uses the downloaded key information to unlock the high-altitude work vehicle 4. The key acquisition user information in Figure 6 stores the user ID of the user who downloaded the key information.

[0067] For example, the equipment ID, reservation date and time information, and reservation company information in Figure 6 may be interpreted as corresponding to "usage reservation status information," and the reservation / key related information DB223 may be interpreted as corresponding to "usage reservation status information storage means."

[0068] For example, the information at the top of Figure 6 indicates that the aerial work platform 401, identified by "EID0001," is reserved by "A Construction" for the morning time slot on March 1st, indicated by "0301-AM." It also indicates that the key information to unlock the aerial work platform 401 during that reserved time slot has been downloaded by the user identified by "UID0001," who belongs to "A Construction." Since multiple users belonging to the company can each download the key information at the same time, multiple user IDs may be stored as key acquisition user information for a common reserved time slot, as shown in the key acquisition user information associated with "Equipment ID" = "EID0002" in Figure 6, where "UID0001,UID0002" is displayed.

[0069] While the method for storing reservation and key-related information is arbitrary, for example, the equipment ID may be one that identifies the aerial work platform 4 whose "return information" is "not yet" among the equipment IDs stored in the equipment-related information in Figure 5. In other words, the equipment ID of the aerial work platform 4 that the general contractor has rented and for which the return operation has not yet been performed may be stored. Furthermore, the reservation date and time information may be based on calendar information. In addition, the reservation company information and key acquisition user information are stored through the reservation processing and key information storage processing described later.

[0070] (Configuration - Server device - Control unit) The control unit 23 in Figure 2 is a control means for controlling the server device 2, and functions, for example, as a key information transmission means. The processing performed by such a control unit 23 will be described later.

[0071] The key information transmission means transmits key information for unlocking the aerial work platform 4 to the terminal device 1 based on the usage reservation status information stored in the usage reservation status information storage means.

[0072] (Configuration - Key management device) The key management device 3 is a device installed on the aerial work platform 4, and specifically, it is a device for locking or unlocking the aerial work platform 4, and is, for example, an operation control means for performing a locking operation or an unlocking operation. As shown in Figure 2, the key management device 3 includes, for example, a communication unit 31, a recording unit 32, and a control unit 33.

[0073] "Locking operation" is a concept that indicates the operation of locking the aerial work platform 4. "Locking" is a concept that indicates that the user is prevented from performing predetermined operations on the operating section 42 shown in Figures 1 to 3. "Locking" is a concept that indicates that, for example, the user is prevented from rotating the knob section 421 in Figure 3 to a certain rotational position (in this embodiment, the "upper operation" position shown in Figure 3(a)), thereby preventing the aerial work platform 4 from being set to upper operation mode. "Predetermined operation" is a concept that corresponds to the operation of rotating the knob section 421 from the "OFF" position (Figure 3(b)) or the "lower operation" position (Figure 3(c)) to the "upper operation" position (Figure 3(a)) to set the aerial work platform 4 to upper operation mode.

[0074] "Unlocking operation" is a concept that indicates the operation of unlocking the aerial work platform 4. "Unlocking" is a concept that indicates enabling the user to perform a predetermined operation on the operating section 42 shown in Figures 1 to 3. "Unlocking" is a concept that indicates enabling the aerial work platform 4 to be set to upper operation mode by releasing (invalidating) the restriction on the rotation of a part of the knob section 421 in Figure 3 to the rotation position of "upper operation" shown in Figure 3(a) in this embodiment (that is, enabling the user to rotate the knob section 421 to the "upper operation" position).

[0075] In this embodiment, regardless of whether the device is locked or unlocked, it is possible to rotate the knob 421 to the "OFF" position (Figure 3(b)) or the "lower operation" position (Figure 3(c)).

[0076] The specific configuration of the key management device 3 for making or enabling predetermined operations of the operating unit 42 impossible is arbitrary, but for example, it may be configured using a stopper mechanism that restricts the rotation of the knob 421 to the "upper operation" position (Figure 3(a)) when locking, and releases the restriction on said rotation when unlocking.

[0077] (Configuration - Key management device - Communication department) The communication unit 31 in Figure 2 is a communication means for communicating with other devices (terminal device 1).

[0078] (Configuration - Key Management Device - Recording Unit) The recording unit 32 in Figure 2 is a storage means for storing the program and various data necessary for the operation of the key management device 3. For example, the recording unit 32 stores the equipment ID that indicates the aerial work platform 4 on which the key management device 3 is installed.

[0079] In this embodiment, for example, the recording unit 32 of the key management device 3 installed in the aerial work platform 401 stores "EID0001," which indicates the aerial work platform 401. Although not shown in Figure 2, the recording units 32 of the key management devices 3 installed in the aerial work platforms 402 and 403 also store "EID0002" and "EID0003," respectively.

[0080] (Configuration - Key Management Device - Control Unit) The control unit 33 in Figure 2 is a control means for controlling the key management device 3. The processing performed by this control unit 33 will be described later.

[0081] (process) Next, the processes performed by the management system 100 according to this embodiment will be described. Specifically, the reservation process, key information storage process, first unlocking process, second unlocking process, unlocking / locking management process, and locking process will be described.

[0082] Unless otherwise specified, the control entity for each of the following processes shall be the control unit of each device, and the description of "control unit" as the control entity may be omitted as appropriate.

[0083] (Processing - Reserved Processing) First, let's explain the reservation process. The "reservation process" is the process of making a reservation to use the aerial work platform 4, for example, the process of storing the reservation company information shown in Figure 6, and is executed by terminal device 1 and server device 2. Figure 7 is a flowchart of the reservation process (in the following explanations of each process, steps will be abbreviated as "S").

[0084] The timing of executing this reservation process is arbitrary, but for example, the system will start when a user making a reservation enters their user ID as login information via the touchpad 12 of their terminal device 1 and performs a predetermined operation. The explanation will begin from the point when the system starts.

[0085] Here, we will explain using an example where the user indicated by "UID0001" in the top row of Figure 4 makes a reservation to use the aerial work platform 401.

[0086] ===SA1=== In SA1 shown in Figure 7, terminal device 1 transmits login information. Specifically, it transmits login information, including the user ID entered by the user when the reservation process is initiated, to server device 2.

[0087] For example, if user "AAA1" enters their user ID "UID0001" when starting the reservation process, terminal device 1 will send login information including "UID0001".

[0088] ===SB1=== Meanwhile, in SB1 in Figure 7, server device 2 receives login information transmitted by SA1. Here, for example, it receives login information including "UID0001".

[0089] ===SB2=== In SB2 of Figure 7, the server device 2 displays a reservation screen on the display 13 of the terminal device 1 based on the login information received by SB1.

[0090] ==Reservation Screen== Figure 8 shows an example of the reservation screen. The "reservation screen" is a screen where information for making a reservation is entered and the reservation status is displayed. As shown in Figure 8, the reservation screen includes, for example, a field 51 for displaying the equipment name and a reservation button 52.

[0091] The equipment name display field 51 is where the name of the aerial work platform 4 that is subject to reservation is displayed.

[0092] The reservation button 52 is operated to make a reservation for use and also displays the current reservation status. The reservation button 52 is provided for each reservation date and time information in Figure 6, and for March 1st in Figure 8, separate reservation buttons 52 are provided for morning and afternoon use reservations.

[0093] This reservation button 52 is displayed in a format corresponding to, for example, "Available," "Completed," or "Other" in Figure 8.

[0094] "Available" is a display mode that indicates that the item is not reserved. For example, by tapping it, information (hereinafter also referred to as "reservation execution information") for reserving the date and time (day and time slot) of use for the corresponding aerial work platform 4 can be entered.

[0095] "Completed" is a display mode that indicates the status of a reservation made by the company (the company to which the user who entered the login information belongs). For example, by tapping it, information to cancel the existing reservation for the corresponding aerial work platform 4 for the date and time (hereinafter also referred to as "reservation cancellation information") will be entered.

[0096] "Other" indicates that the reservation is held by another company (a company other than the one the user who entered their login information belongs to). For example, tapping on it will not result in any information being entered.

[0097] The examples of how to display "empty," "completed," or "other" are arbitrary, as long as they can be distinguished from each other. For example, they may be displayed in different colors, or the text information for "empty," "completed," or "other" may be displayed.

[0098] ==Processing== Specifically, regarding the processing of SB2 in Figure 7, the server device 2 generates screen information for displaying the reservation screen based on the login information received by SB1 and the reservation / key-related information in Figure 6, and transmits the generated screen information to the terminal device 1, thereby displaying the reservation screen on the display 13 of the terminal device 1. In detail, the following steps 1 to 3 are performed.

[0099] =Step 1= In the first step, the user ID included in the login information received by SB1 is obtained, and the company information associated with the obtained user ID is identified by referring to the user-related information in Figure 4.

[0100] <Example of processing> Here, for example, the user ID "UID0001" included in the login information is obtained, and by referring to the user-related information in Figure 4, the company information "A Construction" associated with the obtained user ID is identified.

[0101] =Step 2= In the second step, the reservation company information in the reservation and key-related information of Figure 6 is referenced, and based on the company information identified in the first step and the referenced reservation company information, the display mode of the reservation button 52 for each date and time for each aerial work platform 4 in Figure 8 is determined.

[0102] For example, if no information is stored in the reservation company information in Figure 6, it is identified as "Available". Also, if the reservation company information in Figure 6 contains the same information as the previously identified company information, it is identified as "Completed". Also, if the reservation company information in Figure 6 contains information different from the previously identified company information, it is identified as "Other".

[0103] <Example of processing> Here, for example, although not shown in Figure 6, we will illustrate a case where, in the reservation and key-related information, no information is stored as the reservation company information for "0301-AM", "0301-PM", and "0302-AM" with "Materials ID" = "EID0001", and "C Construction" is stored as the reservation company information for "0302-PM", as shown in Figure 6.

[0104] In this case, the display options for "0301-AM", "0301-PM", "0302-AM", and "0302-PM" in the reservation button 52 for the aerial work platform 401 are specified as "Available", "Available", "Available", and "Other".

[0105] =Step 3= In the third step, the system refers to the equipment-related information in Figure 5 to identify the name of the aerial work platform 4 indicated by each equipment ID in Figure 6. The identified name of the aerial work platform 4 is displayed in the equipment name display field 51 in Figure 8, and the reservation button 52 in the display mode identified in the second step is displayed in the corresponding field. This screen information is generated and transmitted to the terminal device 1 to display the reservation screen.

[0106] <Example of processing> Here, for example, by referring to the equipment-related information in Figure 5, the name of the aerial work platform 4, "EID0001," such as "Unit 1," is identified, and the identified "Unit 1," etc., is displayed, and the reservation button 52 in the display mode identified in the second step is displayed in the corresponding field, as shown in the reservation screen of Figure 8, which is then displayed on the terminal device 1.

[0107] ===SA2=== Meanwhile, in SA2 in Figure 7, terminal device 1 transmits reservation-related input information, which is information about the reservation entered by the user via the reservation screen, to server device 2. Specifically, it transmits reservation execution information or reservation cancellation information entered by the user when they tap the reservation button 52 in Figure 8.

[0108] For example, if a user taps the three "available" reservation buttons 52 for the morning and afternoon of March 1st and the morning of March 2nd for "Unit 1" in Figure 8, the terminal device 1 sends reservation execution information to the server device 2 as reservation-related input information to make a reservation for the use of the aerial work platform 401 for the date and time corresponding to the tapped reservation button 52.

[0109] For example, the reservation execution information transmitted here may be interpreted as corresponding to the "usage reservation information" used to make a usage reservation.

[0110] ===SB3=== Meanwhile, in SB3 in Figure 7, server device 2 receives reservation-related input information transmitted by SA2. Here, for example, it receives the aforementioned reservation execution information.

[0111] ===SB4=== In SB4 in Figure 7, server device 2 stores or deletes the reservation company information shown in Figure 6 based on the reservation-related input information received in SB3.

[0112] =When reservation execution information is received by SB3= Specifically, when SB3 receives reservation execution information as reservation-related input information, SB1 identifies the company to which the user who entered the login information belongs based on the user ID included in the login information received and the user-related information in Figure 4. Then, in the reservation / key-related information in Figure 6, the reservation company information indicating the identified company is stored as reservation company information corresponding to the date and time for the aerial work platform 4 indicated by the reservation execution information received by SB3, and the reservation is made.

[0113] Here, for example, when SB3 receives the aforementioned reservation execution information, SB1 identifies "A Construction" as the company to which the user who entered the login information belongs, based on the user ID "UID0001" included in the login information received by SB1 and the user-related information in Figure 4. Then, in the reservation and key-related information in Figure 6, "A Construction" is stored as the reservation company information for "0301-AM", "0301-PM", and "0302-AM" with "Equipment ID" = "EID0001", as illustrated in Figure 6.

[0114] =When reservation cancellation information is received via SB3= On the other hand, if SB3 receives reservation cancellation information as reservation-related input information, the information stored as reservation company information corresponding to the date and time for the aerial work platform 4 indicated by the reservation cancellation information received by SB3 is deleted, and the reservation is canceled. This completes the reservation process.

[0115] (Processing - Key information storage process) Next, the key information storage process will be explained. The "key information storage process" is the process of downloading and storing key information in terminal device 1, and is performed, for example, by terminal device 1 and server device 2. Figure 9 is a flowchart of the key information storage process.

[0116] The timing of executing this key information storage process is arbitrary, but for example, it will start when a user downloading key information enters their user ID as login information via the touchpad 12 of their terminal device 1 and performs a predetermined operation. The explanation will begin from the point when the process starts.

[0117] Here, we will explain using an example where the user indicated by "UID0001" in the top row of Figure 4 downloads key information.

[0118] ===SC1=== In SC1 of Figure 9, terminal device 1 transmits login information and date / time information. Specifically, the user inputs date / time information (corresponding to the date and time of reservation information in Figure 6) via the touchpad 12, indicating the date and time on which they wish to use the aerial work platform 4. In this case, terminal device 1 transmits the login information, including the user ID entered by the user when the key information storage process is started, and the aforementioned entered date / time information to server device 2.

[0119] For example, if user "AAA1" enters their user ID "UID0001" when starting the reservation process, and also enters "3 / 1AM" (date and time information indicating the morning of March 1) in SC1, terminal device 1 will transmit the login information including "UID0001" and "3 / 1AM".

[0120] ===SD1=== Meanwhile, in SD1 in Figure 9, server device 2 receives login information and date / time information transmitted by SC1. Here, for example, it receives login information including "UID0001" and "3 / 1AM".

[0121] ===SD2=== In SD2 of Figure 9, the server device 2 displays a key information acquisition screen on the display 13 of the terminal device 1 based on the login information and date / time information received by SD1.

[0122] ==Key information acquisition screen== Figure 10 shows an example of the key information acquisition screen. The "key information acquisition screen" is a screen that displays information to allow the user to acquire key information. As shown in Figure 10, the key information acquisition screen includes, for example, a date and time selection field 61 and a key information display image 62.

[0123] The date and time selection field 61 is a field for selecting and entering the desired date and time for using the aerial work platform 4 after the key information acquisition screen is displayed, and it also displays the currently selected date and time. In Figure 10, the currently selected date and time, 3 / 1 AM (morning of March 1st), is hatched, but in practice, this date and time may be highlighted in any manner.

[0124] The key information display image 62 is an image that displays information regarding the key information for unlocking the aerial work platform 4 reserved by the company to which the user who entered login information (hereinafter also referred to as the "logged-in user") belongs. The key information display image 62 is an image that is displayed for each aerial work platform 4 corresponding to the date and time selected by the user, and includes, for example, an information display field 621 and operation buttons 622.

[0125] Information display field 621 is a field that displays various information related to each key. For example, it displays text information such as "Not Downloaded" indicating that the key has not yet been downloaded by the logged-in user, or "Digital Key Available" indicating that the key has already been downloaded by the logged-in user.

[0126] Operation button 622 is a button image that is tapped when performing various operations.

[0127] ==Processing== Specifically, regarding the processing of SD2 in Figure 9, the server device 2 generates screen information for displaying the key information acquisition screen based on the login information, date and time information, and reservation / key-related information in Figure 6 received by SD1, and transmits the generated screen information to the terminal device 1, thereby displaying the key information acquisition screen on the display 13 of the terminal device 1. In detail, the following steps 1 to 4 are performed.

[0128] =Step 1= In the first step, the user ID included in the login information received by SD1 is obtained, and the company information associated with the obtained user ID is identified by referring to the user-related information in Figure 4.

[0129] <Example of processing> Here, for example, the user ID "UID0001" included in the login information is obtained, and by referring to the user-related information in Figure 4, the company information "A Construction" associated with the obtained user ID is identified.

[0130] =Step 2= In the second step, the equipment ID, reservation date and time information, and reservation company information in the reservation and key-related information of Figure 6 are referenced to identify the aerial work platform 4 reserved by the company indicated in the company information identified in the first step at the date and time indicated by the date and time information received by SD1. Then, the key acquisition user information in the reservation and key-related information of Figure 6 is referenced to determine whether the logged-in user has downloaded the key information for each identified aerial work platform 4.

[0131] <Example of processing> Here, we will explain using an example where, for instance, no information is stored as the key acquisition user information associated with "0301-AM" with "Equipment ID" = "EID0001" in Figure 6 (i.e., the key information has not yet been downloaded to the logged-in user and "UID0001" is not stored).

[0132] In this case, the aerial work platform 4 reserved by "A Construction," the company identified in the company information identified in the first step, on the morning of March 1st, which is the date and time indicated by "3 / 1AM" received by SD1, is identified as aerial work platforms 401, 402, etc., indicated by "EID0001" and "EID0002." Next, as the key acquisition user information associated with "E1D0001" and "0301-AM" in Figure 6, (as mentioned above, if "UID0001" has not yet been stored) the same "UID0001" as the login user's user ID (i.e., the user ID included in the login information received by SD1) is not stored, so it is identified that the login user has not downloaded the key information for aerial work platform 401. On the other hand, as the key acquisition user information associated with "EID0002" and "0301-AM" in Figure 6, the same "UID0001" as the login user's user ID is stored, so it is identified that the login user has downloaded the key information for aerial work platform 402.

[0133] =Step 3= In the third step, screen information is generated to display a key information acquisition screen, which includes a key information display image 62 related to the aerial work platform 4 identified in the second step (i.e., the aerial work platform 4 reserved by the company to which the logged-in user belongs at the date and time selected by the logged-in user).

[0134] In detail, in the second step, for the key information display image 62 related to the aerial work platform 4, which is identified as having not had its key information downloaded by the logged-in user, screen information is generated to display "Not Downloaded" in the information display field 621 and "Download Digital Key" on the operation button 622. On the other hand, in the second step, for the key information display image 62 related to the aerial work platform 4, which is identified as having had its key information downloaded by the logged-in user, screen information is generated to display "Digital Key Usable" in the information display field 621 and "Unlock Key" on the operation button 622.

[0135] Furthermore, in the date and time selection field 61 of the key information acquisition screen, the date and time selected by the logged-in user (i.e., the date and time corresponding to the currently displayed key information display image 62) will be highlighted, and screen information will be generated to display a key information acquisition screen that includes information indicating the dates and times before and after that date and time.

[0136] <Example of processing> Here, for example, screen information is generated to display a key information acquisition screen, including key information display images 62 related to the aerial work platforms 401 and 402 identified in step 2. Specifically, in step 2, it was determined that the key information for aerial work platform 401 had not been downloaded, so the key information display image 62 on the left side of Figure 10 is displayed. Furthermore, since it was determined that the key information for aerial work platform 402 had been downloaded, screen information is generated to display the key information display image 62 on the right side of Figure 10. In practice, as shown in Figure 10, the key information display image 62 also displays information indicating the names of the aerial work platforms 4 corresponding to the key information display image 62, such as "Unit 1" and "Unit 2." For this display, the names are identified and displayed by referring to the equipment-related information in Figure 5.

[0137] =Step 4= In the fourth step, the screen information generated in the third step is transmitted to the terminal device 1 to display the key information acquisition screen. Here, for example, the key information acquisition screen shown in Figure 10 is displayed.

[0138] If the user then taps and selects another date and time in the date and time selection field 61, the same processes as described above will be performed for the tapped date and time, and a key information acquisition screen will be displayed showing various information related to that other date and time.

[0139] ===SC2=== Meanwhile, in SC2 of Figure 9, terminal device 1 sends request information to server device 2, which is information for requesting key information (specifically, first key information). Specifically, the user taps the operation button 622 corresponding to the aerial work platform 4 for which they wish to download key information, on the key information acquisition screen of Figure 10 displayed on display 13. In this case, terminal device 1 sends request information requesting the first key information for unlocking the aerial work platform 4 corresponding to the date and time corresponding to the tapped operation button 622.

[0140] Here, for example, if a user views the key information acquisition screen and confirms the key information download status, and then taps the operation button 622 on the key information display image 62 (left side of the drawing) corresponding to "Unit 1" in Figure 10, a request is sent requesting the first key information to unlock the aerial work platform 401 on the morning of March 1st.

[0141] ===SD3=== Meanwhile, in SD3 of Figure 9, server device 2 receives the request information transmitted by SC2. Here, for example, it receives the aforementioned request information.

[0142] ===SD4=== In SD4 of Figure 9, the server device 2 generates first key information corresponding to the request indicated by the request information received in SD3 and transmits it to the terminal device 1.

[0143] "First key information" refers to the key information used to unlock the aerial work platform 4 in the first unlocking mode. The specific contents of this first key information are arbitrary. For example, this explanation will describe a case where it includes the equipment ID of the aerial work platform 4 to be unlocked, and unlocking date and time information indicating the date and time when unlocking is possible (for example, the date and time corresponding to the tapped operation button 622 mentioned above, and one example being information indicating the date and time corresponding to a reservation unit such as the morning of March 1st). Furthermore, for the first key information, any encryption method that can be decrypted by the key management device 3 in Figures 1 and 2 may be used (the same applies to the second key information described later).

[0144] Here, for example, server device 2 generates and transmits first key information, which includes the equipment ID of the aerial work platform 401, "EID0001," and the unlockable date and time information, "3 / 1AM" (that is, information indicating the reservation date and time corresponding to the key information display image 62 on the left side of the drawing in Figure 10, where the user in Figure 10 tapped the operation button 622).

[0145] Furthermore, in the aforementioned SD2, the key information acquisition screen shown in Figure 10 is displayed based on the reservation and key-related information in Figure 6, and in SD4, the first key information corresponding to the key information display image 62 displayed on that screen is displayed. Therefore, it can be interpreted that the server device 2 transmits the first key information to the terminal device 1 based on the reservation and key-related information in Figure 6 (i.e., the usage reservation status information).

[0146] ===SD5=== In SD5 of Figure 9, the server device 2 stores the user ID of the logged-in user as the key acquisition user information corresponding to the first key information transmitted in SD4 in the reservation / key-related information of Figure 6. Here, for example, as shown in the top row of Figure 6, "UID0001" is stored.

[0147] ===SC3=== Meanwhile, in SC3 of Figure 9, terminal device 1 receives the first key information transmitted by SD4 and stores it in recording unit 14. Here, for example, the first key information including "EID0001" and "3 / 1AM" is stored. This completes the key information storage process.

[0148] (Processing - First unlocking process) Next, the first unlocking process will be explained. The "first unlocking process" is a process performed to unlock the aerial work platform 4 in the first unlocking mode, and is, for example, a process to make the aerial work platform 4, which has been reserved for use, available for use for work purposes. The first unlocking process is performed, for example, by the terminal device 1. Figure 11 is a flowchart of the first unlocking process.

[0149] The timing of executing this first unlocking process is arbitrary, but for example, it will be started when the user performs a predetermined operation via the touchpad 12 of their terminal device 1, and the explanation will begin from the point where the process starts (the same applies to the second unlocking process described later).

[0150] Here, we will explain using an example where, for instance, the recording unit 14 of terminal device 1 stores first key information including "EID0001" and "3 / 1AM".

[0151] ===SE1=== In SE1 shown in Figure 11, the terminal device 1 displays the first unlock screen on the display 13 based on the first key information stored in the recording unit 14.

[0152] ==First unlocking screen== Figure 12 shows an example of the display of the first unlocking screen. The "first unlocking screen" is a screen that allows the user to select the key information to be sent to the key management device 3, and as shown in Figure 12, it includes, for example, a date and time display field 71 and a key information display field 72.

[0153] The date and time display field 71 is a field that displays the date and time selected by the user as the date and time they wish to unlock the aerial work platform 4 for use. Figure 12 shows the state in which the morning of March 1st has been selected and is displayed.

[0154] The key information display area 72 is a field that displays various information about the first key information downloaded and stored on the terminal device 1 held by the user. For example, it is a field that displays information about the first key information, including unlockable date and time information corresponding to the date and time displayed in the date and time display area 71. The key information display area 72 includes, for example, a material name display area 721, an unlockable time display area 722, and an unlock button 723.

[0155] The equipment name display field 721 is a field that displays information indicating the name of the aerial work platform 4 that is to be unlocked by the first key information. In Figure 12, "Unit 1" is shown, indicating aerial work platform 401. The unlockable time display field 722 is a field that displays the time period (AM or PM) within the date and time indicated by the unlockable date and time information of the first key information. In Figure 12, "0:00-11:59" is shown, indicating the AM time. The unlock button 723 is a button image that is tapped when transmitting the first unlock signal. The "first unlock signal" is a signal for unlocking the aerial work platform 4 in the first unlock mode, and is, for example, a signal that includes the first key information.

[0156] ==Processing== Specifically, regarding the processing of SE1 in Figure 11, the terminal device 1 first acquires the first key information from the recording unit 14, identifies the date and time indicated by the unlockable date and time information of each acquired first key information, and displays each identified date and time on the display 13. After this, the user selects the desired date and time for unlocking from the displayed dates and times and inputs that date and time via the touchpad 12.

[0157] Next, terminal device 1 displays the first unlock screen based on the entered date and time. Specifically, it displays information indicating the entered date and time in the date and time display field 71. Next, it refers to the unlockable date and time information of each first key information stored in the recording unit 14 to identify the first key information that includes the unlockable date and time information corresponding to the entered date and time, identifies the name of the aerial work platform 4 to be unlocked with the identified first key information, displays the identified name in the equipment name display field 721, displays the time period within the date and time indicated by the unlockable date and time information included in the identified first key information in the unlockable time display field 722, and displays the unlock button 723 for transmitting the first unlock signal including the identified first key information.

[0158] The method for identifying the name of the aerial work platform 4 to be unlocked using the first key information is arbitrary. For example, the recording unit 14 of the terminal device 1 stores information that links the equipment ID and name information shown in Figure 5, and the identification may be based on this information and the equipment ID included in the first key information. Alternatively, for example, the name information of the aerial work platform 4 to be unlocked may also be included in the first key information, and the identification may be based on this name information.

[0159] Here, for example, the first unlocking screen is displayed, showing the information in Figure 12 for the first key information, which includes "EID0001" and "3 / 1AM".

[0160] ===SE2=== In SE2 of Figure 11, terminal device 1 determines whether or not to send the first unlock signal. Specifically, the determination is based on whether or not the unlock button 723 in Figure 12 has been tapped by the user. If the unlock button 723 has not been tapped, it is determined not to send the first unlock signal (SE2 NO), and SA2 is executed again. On the other hand, if the unlock button 723 has been tapped, it is determined to send the first unlock signal (SE2 YES), and the process proceeds to SE3.

[0161] Here, for example, if a user holding terminal device 1 taps the unlock button 723 in Figure 12 at a location near the aerial work platform 401 in Figure 2 (for example, a location about 1m to 2m away where terminal device 1 and the key management device 3 of the aerial work platform 401 can communicate), it is determined that a first unlock signal will be sent.

[0162] ===SE3=== In SE3 of Figure 11, terminal device 1 transmits a first unlock signal. Specifically, it generates a first unlock signal containing first key information corresponding to the unlock button 723 tapped in SE2, and transmits the generated first unlock signal to key management device 3.

[0163] Here, for example, terminal device 1 generates and transmits a first unlocking signal containing first key information having "EID0001" and "3 / 1AM," and this first unlocking signal reaches the key management device 3 of the aerial work platform 401 located around terminal device 1.

[0164] Thus, in the first unlocking process, since the first key information is stored in the terminal device 1, it is possible to send the first unlocking signal to the aerial work platform 4 even in an environment where communication with the server device 2 is not possible.

[0165] For example, the process by which terminal device 1 transmits the first unlock signal may be interpreted as corresponding to the "first unlock-related process." This concludes the first unlock process.

[0166] (Processing - Second unlocking process) Next, the second unlocking process will be explained. The "second unlocking process" is a process performed to unlock the aerial work platform 4 in the second unlocking mode. For example, it is a process to make the aerial work platform 4 usable for the purpose of returning the aerial work platform 4, which has undergone the return process, to the rental company. The second unlocking process is performed, for example, by the terminal device 1 and the server device 2. Figure 13 is a flowchart of the second unlocking process.

[0167] ===SG1=== In SG1 in Figure 13, the server device 2 displays the second unlocking screen on the display 13 of the terminal device 1 that performed a predetermined operation when initiating the second unlocking process, based on the equipment-related information in Figure 5.

[0168] ==Second unlocking screen== Figure 14 shows an example of the second unlocking screen. The "second unlocking screen" is a screen for selecting the aerial work platform 4 to be unlocked, and as shown in Figure 14, it includes, for example, a display field 81 for equipment information.

[0169] The equipment information display area 81 is a field that displays information indicating the aerial work platform 4 that has been returned, and includes, for example, an equipment name display area 811, a return operation date display area 812, and an unlock button 813.

[0170] The equipment name display field 811 is a field that displays information indicating the name of the aerial work platform 4 that has been returned, and in Figure 14, "Unit 3" is shown. The return operation date display field 812 is a field that displays information indicating the date on which the return operation was performed, and in Figure 14, "2022 / 2 / 27" is shown. The unlock button 813 is a button image that is tapped when the second unlock signal is transmitted.

[0171] The "second unlocking signal" is a signal used to unlock the aerial work platform 4 in the second unlocking mode, and is, for example, a signal that includes second key information. The "second key information" is key information used to unlock the aerial work platform 4 in the second unlocking mode. The specific content of this second key information is arbitrary, and for example, we will explain the case where it includes the equipment ID of the aerial work platform 4 to be unlocked. In particular, since the second unlocking mode is unrelated to usage reservations, the second key information does not include the unlocking date and time information included in the first key information mentioned above.

[0172] ==Processing== Specifically, regarding the processing of SG1 in Figure 13, the system refers to the equipment-related information in Figure 5 to identify the aerial work platform 4 for which "Returned" is stored as return information (i.e., the aerial work platform 4 that was the subject of the return process), identifies the date on which the return operation of the identified aerial work platform 4 was performed, and identifies the name of the identified aerial work platform 4. Next, the system displays the second unlocking screen by generating screen information that displays the information indicating the identified name in the equipment name display field 811 of Figure 14, the information indicating the date on which the return operation was performed in the return operation date display field 812, and the corresponding unlock button 813. This information is then transmitted to the terminal device 1 to display the second unlocking screen.

[0173] <Example of processing> Here, for example, by referring to the equipment-related information in Figure 5, the aerial work platform 403 (i.e., aerial work platform 403 with "EID0003") is identified as the aerial work platform 4 for which "Returned" is stored as return information, "2022 / 2 / 27" is identified as the date on which the return operation was performed, and "Unit 3" is identified. Next, the second unlocking screen is displayed on terminal device 1 by generating and transmitting screen information for displaying the second unlocking screen shown in Figure 14.

[0174] ===SF1=== In SF1 of Figure 13, terminal device 1 sends request information to server device 2, which is information for requesting key information (specifically, second key information). Specifically, the user taps the unlock button 813 corresponding to the aerial work platform 4 for which they wish to download key information, on the second unlock screen of Figure 14 displayed on display 13. In this case, terminal device 1 sends request information requesting the second key information to unlock the aerial work platform 4 corresponding to the tapped unlock button 813.

[0175] Here, for example, if a user holding terminal device 1 taps the unlock button 813 corresponding to "Unit 3" in Figure 14 at a location near the aerial work platform 403 in Figure 2 (for example, a location about 1m to 2m away), the device sends request information requesting the second key information to unlock the aerial work platform 403.

[0176] ===SG2=== Meanwhile, in SG2 in Figure 13, server device 2 receives the request information transmitted by SF1. Here, for example, it receives the aforementioned request information.

[0177] ===SG3=== In SG3 in Figure 13, server device 2 generates second key information corresponding to the request indicated by the request information received in SG2 and transmits it to terminal device 1. Here, for example, server device 2 generates and transmits second key information that includes "EID0003", which is the equipment ID of the aerial work platform 403.

[0178] ===SF2=== Meanwhile, in SF2 in Figure 13, terminal device 1 receives the second key information transmitted by SG3. Here, for example, it receives second key information including "EID0003".

[0179] ===SF3=== In SF3 of Figure 13, terminal device 1 transmits a second unlock signal. Specifically, it generates a second unlock signal containing the second key information received in SF2, and transmits the generated second unlock signal to key management device 3.

[0180] Here, for example, terminal device 1 generates and transmits a second unlocking signal containing second key information having "EID0003," and this second unlocking signal reaches the key management device 3 (not shown) of the aerial work platform 403 located around terminal device 1.

[0181] Thus, the second unlocking process is basically performed in an environment where communication can take place between terminal device 1 and server device 2.

[0182] For example, the process by which terminal device 1 transmits the second unlock signal may be interpreted as corresponding to the "second unlock-related process." This concludes the second unlock process.

[0183] (Processing - Unlocking and Locking Management Process) Next, the unlocking and locking management process will be explained. The "unlocking and locking management process" is the process of managing the unlocking or locking of the aerial work platform 4, and is performed, for example, by the key management device 3. Figure 15 is a flowchart of the unlocking and locking management process.

[0184] The timing of executing this unlocking / locking management process is arbitrary, but for example, it will be started when the key management device 3 receives the first unlocking signal or the second unlocking signal, and the explanation will begin from the point where the process starts.

[0185] ===SH1=== In SH1 of Figure 15, the key management device 3 determines whether or not it has received the first unlocking signal when the unlocking / locking management process is initiated. Specifically, the determination may be based on the type of signal itself or the type of information contained in the signal. If it is determined that the first unlocking signal has not been received (i.e., that the second unlocking signal has been received) (SH1 NO), the process proceeds to SH5. If it is determined that the first unlocking signal has been received (SH1 YES), the process proceeds to SH2.

[0186] ===SH2=== In SH2 of Figure 15, the key management device 3 determines whether or not to unlock in the first unlocking mode. Specifically, it first obtains the equipment ID from the recording unit 32 of the key management device 3, and then identifies the current date and time using an arbitrary identification method (for example, assuming that the key management device 3 is equipped with a timing means such as a timer, and identifying the date and time based on the timing result of this timing means). Next, it obtains the first key information contained in the first unlocking signal received when the unlocking / locking management process is started. Next, it compares the equipment ID contained in the obtained first key information with the previously obtained equipment ID (i.e., the equipment ID of the recording unit 32), and also compares the date and time indicated by the unlockable date and time information contained in the obtained first key information with the previously identified current date and time.

[0187] Then, if the compared equipment IDs match and the current date and time falls within the date and time (day and AM or PM time slot) indicated by the unlockable date and time information, the system determines that it has received a first unlock signal to unlock the aerial work platform 4, on which the key management device 3 is installed, in the first unlock mode at the current date and time, and decides to unlock it (YES for SH2), then proceeds to SH3.

[0188] On the other hand, if the compared equipment IDs do not match and are different, or if the current date and time are outside the date and time indicated by the unlockable date and time information (i.e., the current date and time are not included in the date and time indicated by the unlockable date and time information), the system determines that it has not received the first unlock signal to unlock the aerial work platform 4, on which the key management device 3 is installed, in the first unlock mode at the current date and time, and decides not to unlock it (NO in SH2), and terminates the process.

[0189] Here, for example, if the key management device 3 installed on the aerial work platform 401 receives the first unlocking signal (a first unlocking signal including "EID0001" and "3 / 1AM") transmitted by terminal device 1 in SE3 of Figure 11 during the morning of March 1st, the key management device 3 stores "EID0001" and the current date and time falls within the date and time indicated by "3 / 1AM", so it is determined that the device should be unlocked.

[0190] ===SH3=== In SH3 of Figure 15, the key management device 3 unlocks the aerial work platform 4 on which it is mounted in the first unlocking mode (i.e., performs an unlocking operation). Specifically, for example, by releasing the restriction by the stopper mechanism on the rotation of the knob 421 to the "upper operation" position (Figure 3(a)) (i.e., disabling the restriction), the device enables the knob 421 to rotate to the "upper operation" position (Figure 3(a)), thereby enabling the aerial work platform 4 to switch to the upper operation mode. In this case, regardless of whether it is locked or unlocked, the knob 421 can rotate to the "OFF" position or the "lower operation" position as shown in Figures 3(b) to (c), but by unlocking in SH3, it also becomes possible to rotate to the "upper operation" position. In other words, as shown in Figures 3(a) to 3(c), the knob 421 can be freely rotated, allowing the user to switch the aerial work platform 4 between upper operation mode, OFF mode, or lower operation mode as appropriate for performing tasks.

[0191] Furthermore, if the unlocking and locking management process shown in Figure 15 is executed multiple times, it is conceivable that SH3 may be executed multiple times with respect to the same key management device 3 before the aerial work platform 4 is locked. In other words, it is conceivable that the process of unlocking the aerial work platform 4 again may be executed even if it is already unlocked. In this case as well, the same process as described above will be performed, and as a result, the unlocked state in the first mode will be maintained.

[0192] ===SH4=== In SH4 shown in Figure 15, the key management device 3 starts the locking process and then terminates the unlocking / locking management process. The locking process will be described later.

[0193] ===SH5=== On the other hand, in SH5, after determining in SH1 of Figure 15 that the first unlocking signal has not been received (i.e., after determining that the second unlocking signal has been received) (NO in SH1), the key management device 3 determines whether or not to unlock in the second unlocking mode. Specifically, first, it obtains the equipment ID from the recording unit 32 of the key management device 3, and obtains the second key information included in the second unlocking signal received when the unlocking / locking management process is started. Next, it compares the equipment ID included in the obtained second key information with the previously obtained equipment ID (i.e., the equipment ID of the recording unit 32).

[0194] Then, if the compared equipment IDs match, the system determines that it has received a second unlocking signal to unlock the aerial work platform 4, on which the key management device 3 is installed, in the second unlocking mode, and decides to unlock it (YES in SH5), and proceeds to SH6.

[0195] On the other hand, if the compared equipment IDs do not match and are different, the system determines that it has not received a second unlocking signal to unlock the aerial work platform 4, on which the key management device 3 is installed, in the second unlocking mode, and therefore decides not to unlock it (NO in SH5), and terminates the process.

[0196] Here, for example, if the key management device 3 (not shown) installed on the aerial work platform 403 receives the second unlocking signal (second unlocking signal including "EID0003") transmitted by the terminal device 1 in SF3 of Figure 13, the key management device 3 determines that the device should be unlocked because "EID0003" is stored in it.

[0197] ===SH6=== In SH6 of Figure 15, the key management device 3 unlocks the aerial work platform 4 on which it is mounted in the second unlocking mode (i.e., performs the unlocking operation). In detail, it performs the same process as in SH3.

[0198] ===SH7=== In SH4 of Figure 15, if the locking process described later is being executed, the key management device 3 will terminate the unlock / lock management process after completing the locking process. This completes the unlock / lock management process.

[0199] (Processing - Locking process) Next, the locking process will be explained. The "locking process" is the process of locking the aerial work platform 4, and is performed, for example, by the key management device 3. Figure 16 is a flowchart of the locking process.

[0200] This locking process is initiated and started in SH4 in Figure 15. In other words, it is executed in SH3 in Figure 15 after the aerial work platform 4 is unlocked in the first unlocking mode, but it is not executed in SH6 after the aerial work platform 4 is unlocked in the second unlocking mode.

[0201] ===SI1=== In SI1 of Figure 16, the key management device 3 determines whether or not to terminate the locking process. Specifically, it makes this determination based on whether or not the process of SH7 in Figure 15 has been executed. If the process of SH7 in Figure 15 has been executed, it determines that the locking process will be terminated (YES in SI1) and terminates the process. On the other hand, if the process of SH7 in Figure 15 has not been executed, it determines that the locking process will not be terminated (NO in SI1) and proceeds to SI2.

[0202] Here, for example, if the aerial work platform 4 is unlocked in the first unlocking mode and the locking process starts with SH4 in Figure 15, but the aerial work platform 4 has not yet been unlocked in the second unlocking mode, then SH7 in Figure 15 has not been executed, and it is determined that the locking process will not be terminated. Also, for example, if the aerial work platform 4 is unlocked in the first unlocking mode and the locking process starts with SH4 in Figure 15, and then the aerial work platform 4 is unlocked in the second unlocking mode, then SH7 in Figure 15 will be executed, and it is determined that the locking process will be terminated.

[0203] ===SI2=== In SI2 of Figure 16, the key management device 3 determines whether or not to lock the aerial work platform 4. Specifically, there are predetermined locking requirements, and the decision is made based on whether or not these locking requirements are met.

[0204] The locking requirement is optional, but in this embodiment, for example, it is defined as the requirement that the OFF mode remains set for a predetermined time (e.g., 30 to 60 seconds) or longer after the unlocking operation is performed.

[0205] For example, the key management device 3 may be provided with a confirmation unit to check the position of the knob 421 (to check which of the positions shown in (a) to (c) in Figure 3 it is in), and the determination may be made based on the confirmation result of this confirmation unit. The specific configuration of the confirmation unit is arbitrary; for example, a configuration using various sensors (one example being a proximity sensor) may be adopted, or a configuration using a switch to confirm that the knob 421 is located in each of the positions shown in (a) to (c) in Figure 3 may be adopted, or a configuration that confirms based on the rotation angle of the knob 421 may be adopted.

[0206] Then, after unlocking in SH3 in Figure 15 (i.e., unlocking operation in the first unlocking mode), if the knob 421 remains in the "OFF" position for a predetermined time or longer, it is determined that the aerial work platform 4 has been set to OFF mode for a predetermined time or longer after the unlocking operation (i.e., the locking requirement is met), and the aerial work platform 4 on which the key management device 3 is installed is locked (YES in SI2), and the process moves to SI3. On the other hand, after unlocking in SH3 of 15 in Figure 15 (i.e., unlocking operation in the first unlocking mode), if the knob 421 is not continuously set to the "OFF" position for a predetermined time or longer (i.e., if the knob 421 is not rotated to the "OFF" position, or if less than a predetermined time (e.g., 10 seconds) has elapsed since it was rotated to the "OFF" position), it is determined that the aerial work platform 4 has not been set to OFF mode for a predetermined time or longer after the unlocking operation (i.e., it is determined that the locking requirements are not met), and the aerial work platform 4 on which the key management device 3 is installed is not locked (NO in SI2), and SI1 is executed again.

[0207] Here, for example, if, after an unlocking operation, the knob 421 is rotated to the "upper operation" or "lower operation" position, and then switched from the "upper operation" or "lower operation" position to the "OFF" position and a predetermined time has elapsed, or if, after an unlocking operation, the knob 421 remains in the "OFF" position and a predetermined time has elapsed, the system will determine that the aerial work platform 4 is locked.

[0208] ===SI3=== In SI3 of Figure 16, the key management device 3 locks the aerial work platform 4 on which it is mounted (i.e., performs a locking operation). Specifically, for example, it enables the stopper mechanism to restrict the rotation of the knob 421 to the "upper operation" position (Figure 3(a)), making it impossible to switch the aerial work platform 4 to the upper operation mode, and thus ending the process. In this case, regardless of whether it is locked or unlocked, the knob 421 can be rotated to the "OFF" position or the "lower operation" position as shown in Figures 3(b) to (c). By locking in SI3, rotation of the knob 421 to the "upper operation" position becomes impossible, and rotation to the "OFF" position or the "lower operation" position becomes possible. This completes the locking process.

[0209] (Usage example) Next, we will explain typical usage examples of the management system 100. Here, we will explain, for example, the case in which a user of a cooperating company reserves and uses an aerial work platform 4 that the general contractor has rented from a rental company (hereinafter referred to as "Example 1"), the case in which the general contractor returns the aerial work platform 4 that it has rented to the rental company (hereinafter referred to as "Example 2"), and the case in which, after changing the return schedule for the aerial work platform 4 to the rental company, the user of the cooperating company reserves and uses the aerial work platform (hereinafter referred to as "Example 3").

[0210] (Example of use - Example 1) In the first example, the user makes a reservation by tapping the "empty" reservation button 52 on the reservation screen in Figure 8, in an environment where terminal device 1 and server device 2 can communicate with each other (hereinafter referred to as the "online environment"). Next, in the online environment, the user stores the first key information on their terminal device 1 by tapping the operation button 622 on the key information acquisition screen in Figure 10.

[0211] Next, the user, while near the aerial work platform 4 (i.e., at a location where the terminal device 1 and the key management device 3 can communicate), taps the unlock button 723 on the first unlocking screen in Figure 12, thereby sending the first unlocking signal to the key management device 3 of the aerial work platform 4. Note that, since no communication takes place between the terminal device 1 and the server device 2 at this stage, the first unlocking signal can be sent to the key management device 3 regardless of whether the terminal device 1 and the server device 2 are in an environment where they cannot communicate with each other (hereinafter referred to as an "offline environment") or an online environment.

[0212] In this case, the key management device 3 executes SH1 and SH2 in Figure 15, and in SH3, following YES in SH2, it unlocks the aerial work platform 4 to be used in the first unlocking mode. Immediately after this, the locking process shown in Figure 16 is started by executing SH4.

[0213] After this, the user performs the work while appropriately switching the operating mode of the aerial work platform 4. After the work is completed, the user turns the knob 421 of the aerial work platform 4 to the "OFF" position (Figure 3(b)) and moves away from the aerial work platform 4. In this case, after a predetermined time has elapsed since the knob 421 was turned to the "OFF" position, it is determined that the system should be locked by SI2 in Figure 16, and the aerial work platform 4 is automatically locked by SI3.

[0214] (Example of use - Example 2) In the second example, the user, while online, taps the unlock button 813 on the second unlocking screen in Figure 14, thereby sending a second unlocking signal to the key management device 3 of the aerial work platform 4. In this case, the key management device 3 executes SH1 and SH5 in Figure 15, and in SH6, after YES in SH5, unlocks the aerial work platform 4 to be returned in second unlocking mode. In this case, the locking process in Figure 16 is not started, and if the locking process has already started, it is terminated in SH7, so the locking process is not executed.

[0215] In other words, since the aerial work platform 4 is not automatically locked, for example, when a rental company picks up the aerial work platform 4, the driver of the pickup truck can easily move the aerial work platform 4 while appropriately switching its operating mode at any time, load it onto the truck, and transport it to the rental company.

[0216] (Example of use - Example 3) In the third example, the user unlocks the aerial work platform 4 to be returned in the second unlocking mode, as in the second example, and then updates the return information in Figure 5 from "returned" to "not returned" by performing an operation via their computer to cancel the return. Note that the user who performs the operation to update the return information in Figure 5 from "returned" to "not returned" is not limited to the user who tapped the unlock button 813 on the second unlocking screen in Figure 14, but may be another user. Next, as in the first example, the user makes a reservation for use and unlocks the aerial work platform 4 in the first unlocking mode, thereby changing the return schedule and making it possible to use the aerial work platform 4 for work.

[0217] In this case, at SF3 in Figure 13, terminal device 1 sends a second unlocking signal to key management device 3, which unlocks the door in second unlocking mode at SH6 in Figure 15. Subsequently, at SE3 in Figure 11, terminal device 1 sends a first unlocking signal to key management device 3, which unlocks the door in first unlocking mode at SH3 in Figure 15. After this, at SH4 in Figure 15, the locking process shown in Figure 16 is initiated.

[0218] In other words, in the third example, when terminal device 1 transmits a second unlocking signal, key management device 3 performs an unlocking operation, but does not perform a locking operation until terminal device 1 transmits a first unlocking signal.

[0219] (Effects of this embodiment) According to this embodiment, by performing unlocking-related processing (i.e., the first unlocking-related processing and the second unlocking-related processing) for unlocking the aerial work platform 4 in one of the multiple unlocking modes that define matters concerning the locking of the aerial work platform 4 at the time of unlocking, it becomes possible to operate the aerial work platform 4 in accordance with the user's intentions regarding locking.

[0220] [III] Modifications of the Embodiment While embodiments of the present invention have been described above, the specific configurations and means of the present invention can be arbitrarily modified and improved within the scope of the technical idea of ​​each invention described in the claims. Such modifications will be described below.

[0221] (Regarding the problems to be solved and the effects of the invention) First, the problems that the invention aims to solve and the effects of the invention are not limited to those described above, and may vary depending on the implementation environment and details of the invention's configuration. In some cases, only a portion of the problems described above may be solved, or only a portion of the effects described above may be achieved.

[0222] (Regarding decentralization and integration) Furthermore, the above-mentioned components are functional concepts and do not necessarily need to be physically configured as shown in the diagram. In other words, the specific forms of distribution and integration of each part are not limited to those shown in the diagram, and all or part of them can be functionally or physically distributed or integrated in any unit depending on the usage situation. For example, the key management device 3 in Figure 1 may be formed separately from the aerial work platform 4 and then retrofitted to the aerial work platform 4, or it may be formed integrally with the aerial work platform 4.

[0223] (Regarding shape, numerical values, structure, and time series) With regard to the components illustrated in the embodiments and drawings, their shapes, numerical values, or the interrelationships of the structure or time series of multiple components can be arbitrarily modified and improved within the scope of the technical concept of the present invention.

[0224] (Regarding the transmission of unlock signals) The second unlocking process in Figure 13 was described assuming it is performed in an online environment, but this is not the only option. For example, the second key information may be stored in the terminal device 1, similar to the first unlocking signal, and the system may be configured to generate and transmit the second unlocking signal based on this stored second key information, thereby enabling the transmission of the second unlocking signal even in an offline environment.

[0225] (Regarding the completion of the locking process) The process of SI1 in Figure 16 may be omitted, and if SH6 in Figure 15 is executed while the locking process in Figure 16 is running, the system may be configured to interrupt and terminate the ongoing locking process.

[0226] (Regarding the determination of whether the door is locked) In Figure 16, SI2 describes a case where the position of the knob 421 is checked and processing is performed, but this is not the only case. For example, the aerial work platform 4 may be provided with a function to output mode information indicating its current operating mode, and processing may be performed based on the mode information output by this function. For example, if it is confirmed that the OFF mode has been set for the aerial work platform 4 for a predetermined period of time or longer based on the mode information, the aerial work platform 4 may be configured to lock, as this satisfies the locking requirement.

[0227] (Regarding unlocking mode) In addition to the first and second unlocking modes described in the embodiment, a third unlocking mode may be provided. The "third unlocking mode" is a mode for master privilege holders that allows the download of the first key information regardless of which company has made the reservation. For example, master privileges may be granted to prime contractors or periodic inspectors for use in emergencies, and users with such master privileges can download the first key information and unlock the device using a first unlocking signal based on the first key information.

[0228] (Regarding reservations and key information downloads) In this embodiment, we have described a case where the aerial work platform 4 is reserved on a company basis, as shown in the reservation company information of the reservation and key-related information in Figure 6, and the key information is downloaded to the terminal device 1 on a user basis, as shown in the key acquisition user information in the same figure. However, the system is not limited to this configuration. For example, the system may be configured to reserve the aerial work platform 4 on a user basis or on a group basis consisting of multiple users within a company, or the system may be configured to download key information on a company basis or on a group basis.

[0229] (Regarding other features) Other features may be combined as follows: For example, terminal device 1 may generate and transmit a locking signal for locking the aerial work platform 4 based on first key information stored within itself, and key management device 3 may be configured to lock the platform when it receives the locking signal.

[0230] The key management device 3 may be configured to automatically return the knob 421 to the "OFF" position and lock the door at any time (for example, when the reserved time ends, or at a predetermined time).

[0231] The terminal device 1 may be configured to transmit a first unlock signal at regular intervals, and the key management device 3 may be configured to unlock the door while it is receiving this first unlock signal at regular intervals, and to lock the door when the reception of this first unlock signal is interrupted.

[0232] The key management device 3 may be configured to transmit locking or unlocking history information to the terminal device 1, and the terminal device 1 may transmit the history information to the server device 2 at any time, and the server device 2 may store the history information.

[0233] (Regarding terminal devices) Various functions of terminal device 1 may be implemented using any method. For example, an application combining an application for processing reservations for the aerial work platform 4 (hereinafter also referred to as the "reservation application") and an application for processing key information (hereinafter also referred to as the "key application") may be installed on terminal device 1, and the functions may be implemented using the installed application. In this configuration, generally speaking, the reservation application may execute all processing except for processing related to key information, and the reservation application may call the key application to execute the processing related to key information.

[0234] The area in the recording unit 14 of the terminal device 1 where key information is recorded (hereinafter also referred to as the "key information recording area") is generated by the key application and may be configured to perform the following processes. For example, in SC2 of Figure 9, when the user taps the operation button 622 on the key information acquisition screen of Figure 10, the reservation application calls the key application, the called key application sends request information, and thereafter, in SC3 of Figure 9, the key application receives the first key information and stores the first key information in the key information recording area of ​​the recording unit 14. Also, for example, in SE3 of Figure 11 and SF1~SF3 of Figure 13, the reservation application may be configured to call the key application, and the called key application may be configured to execute each process. Note that other processes performed by the terminal device 1 may be configured to be performed by the reservation application.

[0235] The implementation method described here is just one example, and the various functions of terminal device 1 may be implemented using any other implementation method, not limited to this one. (Note) The management system described in Appendix 1 is a management system for managing target equipment to be unlocked or locked, and comprises unlocking means that performs unlocking-related processing to unlock the target equipment in one of a plurality of unlocking modes that define matters concerning the locking of the target equipment at the time of unlocking. The management system in Appendix 2, in the management system described in Appendix 1, includes at least a first unlocking mode in which the target device is locked after unlocking, and a second unlocking mode in which the target device is not locked after unlocking, and the unlocking means performs a first unlocking-related process for unlocking the target device in the first unlocking mode, or a second unlocking-related process for unlocking the target device in the second unlocking mode. The management system in Appendix 3 is a management system described in Appendix 2, wherein the target device is operated by a user to set the target device to a first mode in which a predetermined operation is possible, or a second mode in which the predetermined operation is impossible, and the management system further comprises an operation control means that performs a predetermined operation on the operation means by the user, which is a locking operation that locks the target device by making the predetermined operation for setting the target device to the first mode impossible, or an unlocking operation that unlocks the target device by making the predetermined operation on the operation means by the user possible, and the operation control means performs the locking operation after performing the unlocking operation when the unlocking means has performed the first unlocking-related processing, and the operation control means does not perform the locking operation after performing the unlocking operation when the unlocking means has performed the second unlocking-related processing. The management system in Appendix 4 is a management system described in Appendix 3, wherein the first mode is a horizontal-vertical operation enabled mode in which both horizontal and vertical operations are possible, among horizontal operations relating to the target device or vertical operations relating to the target device; the second mode includes a vertical operation enabled mode in which only the vertical operation among the horizontal or vertical operations is possible, and a horizontal-vertical operation disabled mode in which both horizontal and vertical operations are impossible; the predetermined operation is the horizontal operation; and the operation control means performs the locking operation when the unlocking means has performed the first unlocking-related processing, and after the unlocking operation, the horizontal-vertical operation disabled mode is set for the target device for a predetermined time or longer. In the management system described in Appendix 5, the operation control means, when the unlocking means performs the second unlocking-related processing, refrains from performing the locking operation after the unlocking operation has been performed, at least until the unlocking means performs the first unlocking-related processing. The management program in Appendix 6 is a management program for managing target equipment to be unlocked or locked, and causes a computer to function as an unlocking means that performs unlocking-related processing to unlock the target equipment in one of a plurality of unlocking modes that define matters concerning the locking of the target equipment at the time of unlocking. (Effect of the note) According to the management system described in Appendix 1 and the management program described in Appendix 6, when unlocking, the target device is unlocked using one of several unlocking modes that define matters related to locking the target device. This allows the target device to be operated in accordance with the user's intentions regarding locking. According to the management system described in Appendix 2, by unlocking the target device in a first unlocking mode in which the target device is locked after unlocking, or by unlocking the target device in a second unlocking mode in which the target device is not locked after unlocking, it becomes possible to operate the target device in accordance with the user's intention to lock the target device after unlocking, or the user's intention not to lock the target device after unlocking. According to the management system described in Appendix 3, when the first unlocking-related process is performed, the locking operation is performed after the unlocking operation, and when the second unlocking-related process is performed, the locking operation is not performed after the unlocking operation. This makes it possible to operate the target equipment in accordance with the user's intentions regarding locking, for example. According to the management system described in Appendix 4, when the first unlocking-related process is performed, if the target device is in a mode where horizontal and vertical movement is impossible for a predetermined period of time or longer after the unlocking operation, the target device can be automatically locked by performing a locking operation, for example. This improves the security of the target device and reduces the effort required for the user to lock it. According to the management system described in Appendix 5, when the second unlocking-related process is performed, the locking operation is not performed after the unlocking operation until at least the first unlocking-related process is performed. This allows the target device to be kept in an unlocked state, for example, thus preventing the user from locking it against their will. Description of Symbols
