Description

[0001] This application is a divisional application of the invention patent application with application number 201880099628.8, application date November 22, 2018, entitled "Dynamic Display Device, Dynamic Display System, Dynamic Display Method and Dynamic Display Program". Technical Field

[0002] This invention relates to a dynamic display device, dynamic display system, dynamic display method, and dynamic display program for displaying multiple display objects in motion. Background Technology

[0003] As such a technology, there are known devices that display the current locations of multiple vehicles transporting goods on a user's terminal that manages the operation of the vehicles (see, for example, Patent Document 1). In the device described in Patent Document 1, vehicles that meet the conditions such as departure point, destination, and vehicle type specified by the user via the terminal are extracted, overlaid on map data displayed on the user's terminal screen, and vehicle markers indicating the current locations of the extracted vehicles are displayed in real time.

[0006] Patent document 1: Japanese Patent Application Publication No. 2016-53777. Summary of the Invention

[0007] The problem the invention aims to solve

[0008] However, in the device described in the aforementioned Patent Document 1, the dynamics of vehicles that meet the conditions are only displayed on a single map. When there are many vehicles displayed, or when the displayed vehicles are scattered in multiple areas that are separate from each other, it is difficult to display the dynamics of each vehicle in a way that is convenient for the user.

[0009] In other words, in the device described in Patent Document 1, since all vehicles are displayed on a single map, the map becomes a wide-area display when vehicles are widely dispersed, making it difficult to monitor the activities of each vehicle. Furthermore, when vehicles are scattered across multiple separate areas, users need to manipulate the map to adjust its display position in order to observe the activities of each vehicle, which is inconvenient for the user. Additionally, displaying multiple map views in different locations simultaneously requires multiple monitors or a large display, increasing the overall cost of the device.

[0010] In this step, the display unit is controlled based on the location information obtained in the location information acquisition step to display an icon image representing the current location of the displayed object on the map image in real time; and a display mode switching step is performed, in which the display unit switches between multiple display modes at predetermined time intervals, including a first group display mode that displays icon images of displayed objects belonging to the first group in real time on the display unit and a second group display mode that displays icon images of displayed objects belonging to the second group in real time on the display unit. The display control step includes controlling the display unit to: when the display mode is switched to the first group display mode in the display mode switching step, to display icon images of displayed objects located in a first area pre-defined for the first group in real time; and when the display mode is switched to the second group display mode in the display mode switching step, to display icon images of displayed objects located in a second area pre-defined for the second group in real time. The displayed objects belonging to the first group are workers performing operations in the first area, and the displayed objects belonging to the second group are workers performing operations in the second area.

[0011] Invention Effects

[0012] Using this invention, the dynamics of the displayed object can be shown in a good manner. Attached Figure Description

[0024] The following is for reference Figures 1-10 An embodiment of the present invention will be described. The dynamic display device of this embodiment can be used to display in real time various activities of field personnel, attendees at large facilities, etc., to provide solutions for problem-solving.

[0025] One technical solution of the present invention is a dynamic display device for real-time display of the current positions of multiple display objects belonging to any one of multiple groups, including a first group and a second group. The device comprises: a location information acquisition unit that acquires location information of each of the multiple display objects; a display unit; and a display control unit that controls the display unit based on the location information acquired by the location information acquisition unit to display icon images representing the current positions of the display objects on a map image in real time. The display control unit has a display mode switching unit that switches between multiple display modes at predetermined time intervals, including a first group display mode that displays icon images of display objects belonging to the first group in real time on the display unit and a second group display mode that displays icon images of display objects belonging to the second group in real time on the display unit. The display control unit controls the display unit to: when the display mode is switched to the first group display mode by the display mode switching unit, display icon images of display objects located in a first area pre-defined for the first group in real time; and when the display mode is switched to the second group display mode by the display mode switching unit, display icon images of display objects located in a second area pre-defined for the second group in real time. The display objects belonging to Group 1 are the workers performing operations in Area 1, and the display objects belonging to Group 2 are the workers performing operations in Area 2.

[0026] Another technical solution of the present invention provides a dynamic display system comprising: a dynamic display device and a mobile terminal that moves with the display object and sends the position information of the display object to the dynamic display device.

[0027] Another technical solution of the present invention is a dynamic display method for displaying the current positions of multiple display objects belonging to any one of multiple groups, including a first group and a second group, on a display unit in real time. The method includes: a position information acquisition step, in which position information of each of the multiple display objects is acquired; a display control step, in which the display unit is controlled based on the position information acquired in the position information acquisition step to display icon images representing the current positions of the display objects on a map image in real time; and a display mode switching step, in which the display unit is switched between multiple display modes at predetermined time intervals, including a first group display mode that displays icon images of display objects belonging to the first group on the display unit in real time and a second group display mode that displays icon images of display objects belonging to the second group on the display unit in real time. The display control steps include controlling the display unit to: when the display mode is switched to the first group display mode in the display mode switching step, to display the icon image of the display object located in the first area of ​​the first group in real time; and when the display mode is switched to the second group display mode in the display mode switching step, to display the icon image of the display object located in the second area of ​​the second group in real time. The display object belonging to the first group is the operator performing work in the first area, and the display object belonging to the second group is the operator performing work in the second area.

[0028] Another technical solution of the present invention is a dynamic display program that displays the current positions of multiple display objects belonging to any one of multiple groups, including Group 1 and Group 2, on a display unit in real time. The program enables a computer to perform the following steps: a position information acquisition step, in which position information of each of the multiple display objects is acquired; and a display control step, which constitutes a dynamic display system.

[0029] The following describes an example of a dynamic display system applied to various services provided by sales managers on field trips or delivery personnel, including the delivery of goods, flyers, letters, postcards, and other mail. Specifically, it illustrates an example of a system that displays the real-time activities of delivery personnel performing delivery operations at delivery companies, post offices, and other distribution points.

[0030] In such delivery and distribution services, it is preferable to display the activities (dynamics) of delivery personnel during delivery in a way that is easy for managers to grasp. Therefore, in this embodiment, in order to display the dynamics of each delivery personnel in a way that is easy for managers to grasp, even when there are many delivery personnel to be displayed or when the delivery personnel to be displayed are scattered in multiple separate areas, the dynamic display device is configured as follows.

[0031] [Functional Composition of Dynamic Display System 100]

[0032] First, the functional configuration of the dynamic display system 100 according to an embodiment of the present invention will be described. Figure 1 This is a diagram illustrating an example of the system configuration of the dynamic display system 100. For example... Figure 1 As shown, the dynamic display system 100 includes multiple devices connected via a network 4, including public wireless communication networks such as the Internet and mobile phone networks. Figure 1 It consists of two delivery terminals (1A and 1B), a management server (2), and a manager terminal (3).

[0033] The management server 2 and the manager terminal 3 in such a dynamic display system 100 collectively constitute the dynamic display device 5 of the embodiment of the present invention. It should be noted that the management server 2 or the manager terminal 3 can also constitute the dynamic display device 5 independently. Furthermore, the network 4 also includes a closed communication network set up in each designated management area, such as a wireless LAN (local area network), Wi-Fi (Wireless Fidelity) (registered trademark), etc.

[0034] Delivery terminals 1A and 1B can be stored in the pockets of clothing, bags, or small pouches of delivery personnel A and B, or mounted on the brackets of vehicles 6A and 6B used in delivery operations. In this embodiment, smartphones, tablets, mobile phones, PDAs (Personal Digital Assistants), and various wearable terminals capable of public wireless communication connections are collectively referred to as delivery terminals 1A and 1B.

[0035] Delivery terminal 1A and delivery terminal 1B share a common configuration. It should be noted that there can be three or more delivery terminals 1A and 1B. Vehicles 6A and 6B are transport vehicles such as four-wheeled vehicles, motorcycles, bicycles, and handcarts. As an example, Figure 1 The image shows a light-duty vehicle 6A and a bicycle 6B equipped with a prime mover, widely used for the delivery and distribution of goods, leaflets, letters, postcards, and other mail. Delivery personnel A and B can also perform delivery operations on foot without using vehicles 6A and 6B.

[0036] Next, we will explain the components of delivery terminal 1A, 1B, management server 2, and manager terminal 3.

[0037] <Delivery Terminals 1A and 1B>

[0038] First, delivery terminals 1A and 1B will be described. Various application software can be installed on delivery terminals 1A and 1B. In this embodiment, delivery terminals 1A and 1B constitute a dynamic display system using application software installed on a smartphone. By using commercially available smartphones, the cost of building the system can be controlled.

[0039] Figure 2 This is a block diagram showing the general structure of delivery terminals 1A and 1B. (Example) Figure 2 As shown, the delivery terminal 1A has a control unit 10, a storage unit 11, a wireless unit 12, a sensor unit 13, a display unit 14, and an input unit 15.

[0040] The storage unit 11 consists of a semiconductor memory, a hard disk, and other components. The storage unit 11 stores various information, including an operating system (OS), software such as applications supporting delivery and distribution operations, map information such as road maps and residential maps, and customer information for delivery destinations. The customer information includes not only the address and phone number of the delivery destination but also customer-related information such as the availability of parcel lockers. It should be noted that the software, map information, and customer information can be pre-stored in the storage unit 11 or retrieved from the management server 2.

[0041] The wireless unit 12 includes a DSP (Digital Signal Processor) and is configured to communicate wirelessly with the management server 2 via wireless communication networks such as 3G, LTE (Long Term Evolution), 4G, and 5G mobile phone networks. The wireless unit 12 can also be configured as a short-range wireless communication unit (not shown) capable of using short-range wireless communication technologies such as Wi-Fi and Bluetooth. The wireless unit 12 can send the login ID (also called "delivery ID") used to identify delivery personnel A and B, the current location information of delivery personnel A and B, or vehicles 6A and 6B, and speed information to the management server 2.

[0042] The sensor unit 13 consists of a GPS sensor 13a that receives positioning signals from multiple GPS (Global Positioning System) satellites and determines the absolute positions (latitude and longitude) of the corresponding delivery personnel A and B, and a gyroscope sensor 13b that detects angular velocity. In the event that positioning signals from GPS satellites cannot be received, AGPS (Assisted Global Positioning System) communication can be used to calculate the current positions of delivery personnel A and B or vehicles 6A and 6B based on base station information from the wireless communication network obtained from the wireless unit 12.

[0043] The display unit 14 is composed of a display device such as a liquid crystal display or an organic EL panel. The display unit 14 can receive instructions from the control unit 10, display maps, icons of operation buttons for touch panels, and various information such as the current location of delivery personnel A and B or vehicles 6A and 6B, the surrounding area of ​​the current location, and maps of the delivery destination.

[0044] The input unit 15 consists of physical switches such as numeric keys operated by delivery personnel A and B, and input devices (not shown) such as a touch panel superimposed on the display surface of the display unit 14. Based on the operation input from the input unit 15, such as delivery personnel A and B pressing numeric keys or pressing the touch panel, the generated signals are output to the control unit 10, thereby enabling delivery personnel A and B to perform operations such as switching the screen display on the display unit 14.

[0045] In addition, delivery terminals 1A and 1B may also include speakers, vibrators, lights, microphones, etc. (illustrations omitted). The speakers, vibrators, and lights communicate various information to the delivery person through sound, vibration, and light. Furthermore, the speakers output voice messages to the delivery person, and the microphone picks up the voice messages spoken by the delivery person. Thus, various information can be output from the speakers via voice, and voice recognition technology can be used to input various commands spoken by the delivery person via the microphone into the control unit 10.

[0046] The control unit 10 is configured with a microprocessor including a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read-Only Memory), and I / O (Input / Output Interface). The CPU executes a pre-stored program and transmits and receives signals with the storage unit 11, the wireless unit 12, the sensor unit 13, the display unit 14, and the input unit 15. The control unit 10 has a display control unit 101, a connection processing unit 102, and a location information notification unit 103 as its functional structure.

[0047] The display control unit 101 generates image signals based on the operation of the input unit 15 or the reception of various information by the wireless unit 12, and sends them to the display unit 14, thereby controlling the screen display of the display unit 14. The screen displayed on the display unit 14 by the display control unit 101 includes a login screen for logging into the dynamic display system 100, etc.

[0048] The connection processing unit 102 transmits the login ID and password entered by delivery personnel A and B through the input unit 15 on the login screen displayed on the display unit 14 to the management server 2 via the wireless unit 12. Thus, delivery personnel terminals 1A and 1B are connected to the management server 2 in a communicable state. When a delivery person begins work, that is, when the delivery person departs from the delivery point, the login input performed by that delivery person is executed.

[0049] Furthermore, when a logout is entered via input unit 15, connection processing unit 102 sends a logout message to management server 2 via wireless unit 12. This terminates the communication connection between delivery personnel terminals 1A and 1B and management server 2. The logout input made by the delivery personnel is executed when they finish their work, i.e., when they return to the delivery point. It should be noted that logout can also be executed automatically based on time and location information when the delivery personnel return to the delivery point.

[0050] The location information notification unit 103 establishes a correspondence between the current location information of delivery personnel A and B or vehicles 6A and 6B that move with delivery personnel terminals 1A and 1B, calculated based on the GPS signal received by the sensor unit 13 (GPS sensor 13a), and the delivery personnel ID, and sends it to the management server 2 via the wireless unit 12 at a predetermined time interval (e.g., 1 second interval).

[0051] The locations of delivery personnel A and B, or vehicles 6A and 6B, are constantly changing. Therefore, when current location information is obtained at specified time intervals, the location calculated based on the most recent current location information may not strictly differ from the actual location. However, because the deviation is small, the location calculated based on the current location information obtained at specified time intervals can be considered the current location.

[0052] Additionally, it is possible to aggregate and send multiple pieces of current location information of delivery personnel A and B or vehicles 6A and 6B at specified time intervals at once (so-called burst sending). The time interval for obtaining the current location information of delivery personnel or vehicles (e.g., 1-second interval) and the number of pieces sent at once when multiple pieces are aggregated for burst sending can be preset.

[0053] <Management Server 2>

[0054] Next, management server 2 will be described. In this embodiment, management server 2 will be described as a single server with various functions, but it can be a distributed server in which each function is composed of different servers, or it can be implemented by a cloud server (virtual server).

[0055] Figure 3 This is a block diagram showing the general structure of management server 2. (Example) Figure 3 As shown, the management server 2 includes a control unit 20, a storage unit 21, a communication unit 22, a display unit 24, and an input unit 25. It should be noted that the display unit 24 and the input unit 25 can be omitted. Alternatively, the display unit 24 and the input unit 25 can be configured using other information terminals (not shown) connected to the management server 2.

[0056] The storage unit 21 is composed of semiconductor memory, hard disk drive, etc. The storage unit 21 stores the operating system (OS), software called applications, and various other information. Therefore, the storage unit 21 stores various storage areas such as the delivery person information area 211, the vehicle information area 212, the delivery destination or distribution destination information area 213, and the map information area 214. It should be noted that the information areas are, for example, tables in a database management system.

[0057] In the deliveryman information area 211, for each employee ID (also called "deliveryman ID") that serves as identification information for deliverymen A and B, basic information related to deliverymen A and B is stored, such as their names, affiliated delivery outlets, and affiliated delivery teams. Additionally, the deliveryman information area 211 stores information about the delivery areas that each delivery team to which deliverymen A and B belong is responsible for in delivery and distribution operations.

[0058] The information stored in the deliveryman information area 211 includes the location information (latitude and longitude) of the representative point (center point) when each responsible area is displayed on the map, as well as the scale information, or the location information (latitude and longitude) of the diagonal vertex when each responsible area is displayed on the map.

[0059] Additionally, the vehicle used by the delivery person is stored in the delivery person information area 211, specifically the vehicle ID, which is stored as the identification information for vehicles 6A and 6B and is associated with the delivery person ID. The association between the vehicle ID and the delivery person ID is pre-set by the delivery network manager, for example, before the start of a day's delivery operations.

[0060] In the vehicle information area 212, for each vehicle ID, information related to that vehicle is stored, such as the type of vehicle, such as a four-wheeled vehicle, a motorcycle, or a bicycle, and the size of the cargo box.

[0061] In the delivery destination or distribution destination information area 213, information about the distribution destination, including the address, telephone number, and delivery area containing the distribution destination, is stored. It should be noted that the delivery area is an area pre-set by the manager of the distribution network to facilitate the allocation of delivery and distribution operations to each delivery person, and consists of, for example, 10 to 30 delivery destinations equivalent to one or more blocks.

[0062] The delivery personnel information area 211 stores the responsibility areas assigned to the delivery teams to which delivery personnel A and B belong, which consist of multiple delivery areas. Delivery personnel A and B, belonging to their respective delivery teams, are responsible for delivery and distribution operations within the responsibility areas assigned to their respective delivery teams.

[0063] Map information such as road maps and residential maps is pre-stored in map information area 214. This map information includes road link information and display map data used to show the background of roads and road maps. This map information is updated regularly.

[0064] When the communication unit 22 is used to transmit and receive information with delivery terminals 1A and 1B, it is equipped with communication protocols capable of wireless communication such as 3G, LTE, 4G, and 5G. On the other hand, when the communication unit 22 is used to transmit and receive information with the manager terminal 3, it is equipped with communication protocols capable of wired communication (such as internet lines) or wireless communication.

[0065] The control unit 20 is configured with a processor including a CPU, RAM, ROM, I / O, etc. The control unit 20 has a connection processing unit 201, a position information acquisition unit 202, a display control unit 203, a display mode switching unit 204, a dwell determination unit 205, a non-communication determination unit 206, and an information output unit 207 as its functional structure.

[0066] The connection processing unit 201 performs login processing from delivery terminal 1A and 1B, establishing a connection with delivery terminal 1A and 1B. Additionally, the connection processing unit 201 performs logout processing from delivery terminal 1A and 1B, terminating the connection with delivery terminal 1A and 1B. Furthermore, the connection processing unit 201 performs login processing from administrator terminal 3, establishing a connection with administrator terminal 3, and performs logout processing from administrator terminal 3, terminating the connection with administrator terminal 3.

[0067] The location information acquisition unit 202 acquires various information by receiving data sent from delivery terminal 1A, 1B to management server 2 via communication unit 22. The information acquired by the location information acquisition unit 202 includes the location information of delivery personnel A, B, or vehicles 6A, 6B sent from the location information notification unit 103 of each delivery terminal 1A, 1B. The location information is specifically expressed in latitude and longitude.

[0068] The display control unit 203 generates image signals and sends them to the administrator terminal 3 according to the instructions from the administrator terminal 3, so that various images are displayed on the display unit 34 of the administrator terminal 3.

[0069] Based on the location information obtained by the location information acquisition unit 202, the loitering determination unit 205 determines whether the delivery personnel A and B or the vehicles 6A and 6B are in a loitering state where they have stayed for a specified time (e.g., more than 3 minutes) within a specified range (e.g., within a radius of 5m).

[0070] The non-communication determination unit 206 determines whether the delivery personnel A and B or the vehicles 6A and 6B are in a non-communication state where location information cannot be obtained by the location information acquisition unit 202 for more than a specified time (e.g., more than 3 minutes).

[0071] Figure 4 , Figure 5 , Figures 7A-8 This is an example of a display DP shown on the display unit 34 of the manager terminal 3. It shows a display DP shown on the manager terminal 3 of a delivery network that manages 30 deliverymen 01 to 30.

[0072] Figure 4 This is an example of the initial screen display (DP) shown on the display unit 34 of the administrator terminal 3 when the connection processing unit 201 performs connection processing with the administrator terminal 3 according to instructions from the administrator terminal 3. Figure 4 In the example, a dynamic image DP1 is displayed on the map image MAP, showing the current locations of deliverymen 01 to 30, with location icons PI01 to PI30 overlapping. A menu DP2 is displayed to the left of the dynamic image DP1.

[0073] In the initial state of the dynamic image DP1, based on the network manager ID input via the manager terminal 3, the current locations of delivery personnel 01 to 30 belonging to delivery groups 1 to 3 managed by the network manager are displayed in real time (dynamic display mode). The scale and center position of the map in the dynamic image DP1 can be appropriately changed via the input unit 35 of the manager terminal 3, such as a touch panel or mouse provided on the display unit 34.

[0074] When a deliveryman dynamically displayed in the dynamic image DP1 is determined by the demurrage determination unit 205 to be in a demurrage state, the location icon PI showing that deliveryman's current location P is displayed in a different way than the location icons PI showing the current locations P of other deliverymen. For example, it can be displayed in a recognizable way, such as by changing the display color of the location icon PI or by flashing the location icon PI. Alternatively, a warning message can be displayed on the screen DP indicating the presence of a deliveryman determined to be in a demurrage state.

[0075] At the top of menu DP2 is an automatic switching button BT1 that, as described later, turns the automatic switching function of the dynamic image DP1 display mode on or off. At the bottom of menu DP2, for each of the delivery groups 1 to 3 managed by the delivery network manager, dynamic map display buttons BT61 to BT63 and drop-down menus DD1 to DD3 are displayed in the dynamic image DP1, showing only the dynamic map of the delivery personnel of each delivery group 1 to 3.

[0076] Below the automatic switching button BT1, there is a full display button BT2 that shows all the activity data for delivery personnel 01 to 30, and a full hide button BT3 that hides all activity data. Also, there is a full collapse button BT4 that collapses all drop-down menus DD1 to DD3, and a full expand button BT5 that expands all drop-down menus.

[0077] Figure 5 , Figures 7A-8 These are examples of the display screen DP shown when the map display buttons BT61 to BT63 are pressed via the touch panel (input unit 35) of the administrator terminal 3.

[0078] exist Figure 5 The dynamic image DP1 displays in real time the current positions of 5 delivery personnel (06-10) belonging to delivery group 1 (01-10) who are logged into the dynamic display system 100, specifically their position icons PI06-PI10 (Group 1 display mode). The current positions of delivery personnel (01-05) who have exited the dynamic display system 100 are not displayed. The name of the delivery group, "Group 1," is displayed in the upper left corner of the dynamic image DP1.

[0079] Figure 6 This is a diagram used to illustrate the status of delivery terminals 1A and 1B. For example... Figure 6As shown, the status (status, deliveryman status) of each delivery terminal 1A and 1B includes a logged-in status and a logged-out status. Furthermore, the logged-in status of delivery terminals 1A and 1B includes a communicable state where location information has been obtained by the location information acquisition unit 202 of management server 2 within a specified time (e.g., 3 minutes), and a non-communicable state where location information has not been obtained within the specified time. Non-communicable states include situations such as the delivery terminals 1A and 1B running out of battery power or a network 4 malfunction.

[0080] Regarding delivery personnel in a state of non-communication (in) Figure 4 , Figure 5 In the example of deliveryman 10, the location icon PI10 of the last obtained current location P10 is displayed in a different way than the location icons PI of other deliverymen's current locations P. For example, it is displayed in a recognizable way, such as by changing the display color of location icon PI10 or by flashing location icon PI. That is, it is recognizable by displaying the determination result of the non-communication determination unit 206 that deliveryman 10 is in a non-communication state where location information cannot be obtained.

[0081] In menu DP2, the drop-down menu DD1 of delivery group 1, which is displayed in the dynamic image DP1, is highlighted. The drop-down menu DD1 clearly shows whether 5 of the 10 delivery personnel belonging to delivery group 1 are logged in or the remaining 5 are logged out.

[0082] And, as Figure 5 As shown, when the drop-down menu DD1 is expanded, the status (login or logout status) of each of the 10 deliverymen 01-10 belonging to delivery group 1 is displayed and can be identified. Furthermore, for the 5 deliverymen 06-10 who are logged in, in addition to their status, the type of vehicle they are using is displayed, and a checkbox CB is shown.

[0083] By pressing the checkbox CB for each deliveryman 06 to 10 via the touch panel (input unit 35) of the administrator terminal 3, it is possible to individually switch the display or non-display of the current position P06 to P10 of each deliveryman 06 to 10 in the dynamic image DP1.

[0084] exist Figure 7A , 7B The dynamic image DP1 displays in real-time the current locations of the 10 delivery personnel (11-20) belonging to delivery group 2, with location icons PI11-PI20 (group 2 display mode). Comparison Figure 7A , Figure 7B Map image MAP, Figure 7B The display of the map image MAP is greater than Figure 7AThe map image MAP can be made larger or smaller.

[0085] For example, suppose that when all delivery drivers are displayed in a logged-in state, the usual delivery time is... Figure 7A Such a display, then in Figure 7B In such a display scenario, the managers of the delivery network would be able to notice the anomaly. That is, such as... Figure 7B As shown, when a delivery person moves to a location different from the usual one, the map scale and display location change to a different state, so that managers can easily identify the different situation.

[0086] In the dynamic display of each delivery group 1 to 3, the scale and center position of the map in the dynamic image DP1 are automatically adjusted to display the current location of all logged-in delivery personnel belonging to each delivery group. The map in the dynamic image DP1 can also be configured to display a pre-defined area, such as a responsibility area, for each of the delivery groups 1 to 3, regardless of the delivery personnel's current location.

[0087] exist Figure 8 In the dynamic image DP1, the current locations of the three deliverymen 21 to 23 who are logged in among the ten deliverymen 21 to 30 belonging to delivery group 3 are displayed in real time, with location icons PI21 to PI23 (third group display mode).

[0088] exist Figure 8 In menu DP2, the automatic switching button BT1 is highlighted. Figures 4 to 7B When the automatic switching button BT1 of menu DP2 is pressed via the touch panel (input unit 35) of the administrator terminal 3, the automatic switching button BT1 is highlighted, and the automatic switching function of automatically switching the display mode of dynamic image DP1 is activated.

[0089] It should be noted that when the automatic switching function is enabled, when the map display buttons BT61 to BT63 of menu DP2 are pressed via the touch panel (input unit 35) of the manager terminal 3, the automatic switching function is disabled and the display mode for each delivery group is switched.

[0090] Furthermore, when the automatic switching function is enabled, the automatic switching function is disabled when operations such as the map scale and center position in the dynamic image DP1 are performed via the touch panel (input unit 35) of the administrator terminal 3. In this case, the display mode remains unchanged as when the automatic switching function was disabled, and the automatic switching function remains disabled.

[0091] like Figure 3As shown, the display control unit 203 has a display mode switching unit 204. When the automatic switching function is activated according to the command input via the touch panel (input unit 35) of the manager terminal 3, the display mode switching unit 204 sequentially switches to the first to third group display modes that display the dynamics of the delivery personnel in each of the delivery groups 1 to 3.

[0092] Specifically, the system switches between display modes for groups 1 through 3 every specified time interval (e.g., 5 seconds). It can also automatically switch between a full group display mode showing the dynamics of all delivery groups 1 through 3 and the group 1 through 3 display modes every specified time interval.

[0093] Figure 3 The information output unit 207 sends data from the management server 2 to the management terminal 3 via the communication unit 22, thereby outputting various information. The information output by the information output unit 207 includes image signals generated by the display control unit 203 and sent to the management terminal 3.

[0094] Figure 9 This is a flowchart illustrating an example of a process executed by the CPU of management server 2 according to a pre-stored program. The process shown in the flowchart begins when an instruction is received from the administrator terminal 3 and repeats at a predetermined cycle.

[0095] First, in step S1, the automatic switching function is determined to be enabled by the processing of the display mode switching unit 204. If step S1 is affirmative (S1: Yes), the process proceeds to step S2; if it is negative (S1: No), the process ends. In step S2, it is determined whether a predetermined time has elapsed since the switch to the currently displayed display mode. If it is affirmative (S2: Yes), the process proceeds to step S3; if it is negative (S2: No), the process proceeds to step S4.

[0096] In step S3, the location information of deliverymen A and B, displayed in the next display mode, is read through the processing of the location information acquisition unit 202. Conversely, in step S4, the location information of deliverymen A and B, displayed in the current display mode, is read. Next, in step S5, the image signal of the dynamic image DP1 is generated based on the location information acquired in step S3 or S4 through the processing of the display control unit 203. Finally, in step S6, the image signal generated in step S5 is sent to the manager terminal 3 through the processing of the information output unit 207.

[0097] Delivery network managers can easily monitor the movement of delivery personnel within their managed areas by simply pressing the automatic switching button BT1 displayed on the display unit 34 via the touch panel, mouse, or other input unit 35 on the display unit 34 of the manager terminal 3. The system displays the movement of delivery personnel for each delivery group operating within their assigned area, thus enabling them to monitor the activities of each delivery person even when there are many delivery personnel within the managed area and they are scattered across multiple separate areas.

[0098] <Administrator Terminal 3>

[0099] Next, the administrator terminal 3 will be described. Administrator terminal 3 is used by the managers of the delivery network to confirm the real-time location of delivery personnel A and B who are carrying out delivery operations. Administrator terminal 3 includes various computers such as personal computers, tablet computers, and smartphones equipped at the delivery network, and communicates with the management server 2 via network 4.

[0100] Figure 10 This is a block diagram showing the general structure of the administrator terminal 3. (Example) Figure 10 As shown, the administrator terminal 3 has a control unit 30, a storage unit 31, a communication unit 32, a display unit 34, and an input unit 35.

[0101] Storage unit 31 consists of semiconductor memory, hard disk drive, etc. Storage unit 31 stores the operating system (OS), software called applications, and various other information. The software stored in storage unit 31 includes applications used to manage delivery and distribution operations.

[0102] The communication unit 32 is equipped with communication protocols that enable wired communication (such as Internet lines) or wireless communication such as 3G, LTE, 4G, and 5G, and connects to the management server 2 for sending and receiving.

[0103] The display unit 34 is composed of a display device such as a liquid crystal display or an organic EL (electroluminescent) panel. It receives instructions from the control unit 30 and displays maps, icons of operation buttons for the touch panel, etc. Furthermore, the display unit 34 displays various images based on image signals sent from the information output unit 210 of the management server 2.

[0104] The input unit 35 consists of physical switches such as numeric keys operated by the administrator, and input devices (not shown) such as a touch panel superimposed on the display surface of the display unit 34. Switching commands for the display screen of the display unit 34 are input through the input unit 35. The input unit 35 can also be used to set the responsibility areas (departmentalization of delivery destinations) for each delivery group.

[0105] The control unit 30 is configured with a processor including a CPU, RAM, ROM, I / O, etc. The control unit 30 has a functional structure including a display control unit 301, a connection processing unit 302, a dynamic display request unit 303, and a server information acquisition unit 304.

[0106] The display control unit 301 generates image signals based on the operation of the input unit 35 and sends them to the display unit 34, thereby controlling the screen display on the display unit 34. The screens displayed on the display unit 34 by the display control unit 301 include a login screen for logging into the dynamic display system 100, a setting screen for setting the responsibility area of ​​the delivery team, etc.

[0107] The connection processing unit 302 performs login processing on the management server 2, for example, using an identification number (site manager ID) and password to identify the manager or person in charge of the delivery site.

[0108] The dynamic display request unit 303 sends an output request (instruction) for displaying the dynamic image DP1 to the management server 2 based on the administrator's operation on the input unit 35. For example, when the connection processing unit 302 performs login processing, it simultaneously sends an output request for displaying the dynamic image DP1 to the management server 2.

[0109] The server information acquisition unit 304 acquires image signals, etc., sent from the management server 2 (information output unit 207). When the server information acquisition unit 304 acquires an image signal, it displays various images on the display unit 34. Figure 4 , Figure 5 , Figures 7A-8 ).

[0110] [Dynamic display system 100's actions]

[0111] Next, an example of the operation of the dynamic display system 100 will be described. When deliverymen A and B, driving vehicles 6A and 6B respectively, depart from, for example, a delivery point to begin work, they enter their login ID and password through the input unit 15 on the login screen displayed on the display unit 14 of the deliveryman terminals 1A and 1B. When this input is made, the management server 2 performs connection processing with the deliveryman terminals 1A and 1B.

[0112] Afterwards, delivery terminals 1A and 1B communicate with management server 2 at specified time intervals (e.g., 1-second intervals) to send the location information of delivery personnel A and B or vehicles 6A and 6B to management server 2. Communication between delivery terminals 1A and 1B and management server 2 continues until delivery terminals 1A and 1B perform an exit operation.

[0113] On the other hand, the manager of the delivery point operates the touch panel (input unit 35) of the manager terminal 3 to launch the application for managing delivery and distribution operations, and enters the delivery point manager ID and password on the login screen displayed on the display unit 34. When this input is made, the management server 2 performs connection processing with the manager terminal 3.

[0114] Based on instructions from the manager terminal 3, the management server 2 generates image signals displaying the current location P of the delivery person corresponding to the network manager ID, dynamic image DP1, and menu DP2, and sends them to the manager terminal 3. When the delivery network manager presses the automatic switching button BT1 of menu DP2 displayed on the display unit 34 to activate the automatic switching function, the dynamic image DP1 of each delivery group automatically switches and displays sequentially. Figure 9 Steps S1 to S6) Figure 4 , Figure 5 , Figures 7A-8 ).

[0115] Therefore, managers of delivery outlets can effectively monitor the movement of delivery personnel under their management. This is achieved based on the number and density of the delivery personnel being managed, such as... Figure 4 As shown, when all delivery personnel's current locations are displayed at once, the map is displayed in a wide area, and the location icons (PI) representing each delivery personnel's current location overlap, making it difficult to grasp the current location and activities of each delivery personnel.

[0116] On the other hand, in order to track the current location and activities of each delivery person, users acting as managers can manually manage... Figure 5 , Figures 7A-8 The map scale and center position shown can be confusing for users. To address this, the dynamic display device 5 automatically switches to a different scale. Figure 5 , Figures 7A-8 or Figure 4 , Figure 5 , Figures 7A-8 The display mode is used to display dynamic images DP1, so managers can keep abreast of the ever-changing dynamics of delivery personnel from multiple perspectives.

[0117] To monitor the movements of delivery personnel belonging to multiple groups from multiple perspectives, it is possible to display multiple display modes of the video feed (DP) on multiple monitors. However, in this case, each video feed (DP) is scaled down or requires a large monitor as the display unit 34. In this regard, the dynamic display device 5 automatically switches the display mode at appropriate time intervals to display the dynamic image (DP1). Therefore, even if the display unit 34 is a relatively small monitor such as a tablet computer, it is possible to monitor the constantly changing movements of the delivery personnel from multiple perspectives.

[0118] The following effects can be achieved by adopting this implementation method.

[0119] (1) The dynamic display device 5 displays the current location P of multiple delivery personnel belonging to any one of the multiple delivery groups 1 to 3 in real time. Figure 4 , Figure 5 , Figures 7A-8 The dynamic display device 5 includes: a location information acquisition unit 202 that acquires location information of multiple delivery personnel; a display unit 34; and a display control unit 203 that controls the display unit 34 based on the location information acquired by the location information acquisition unit 202 to display a location icon PI representing the current location P of a delivery person in real time on a map image MAP. Figure 3 , Figure 10 ).

[0120] The display control unit 203 has a display mode switching unit 204, which switches between multiple display modes at predetermined time intervals, including display modes of groups 1 to 3 that display the location icons PI of delivery personnel belonging to delivery groups 1 to 3 in real time. Figure 3 This allows delivery network managers to effectively track the current locations of all delivery personnel and gain a detailed understanding of each delivery person's current status.

[0121] In other words, by dynamically displaying each group, the map is prevented from becoming too broad, and a view that is easy for managers to observe is provided. Furthermore, the display of each group switches automatically, so managers do not need to adjust the map scale or display position, allowing them to focus on the dynamics.

[0122] (2) The dynamic display device 5 also has an input unit 35 for receiving instructions from the manager of the distribution network. Figure 10 The display control unit 203 stops the display mode switching implemented by the display mode switching unit 204 based on the instruction received from the input unit 35. Therefore, automatic switching can be stopped as needed, allowing for effective monitoring of delivery personnel's activities even when there are delivery groups or delivery personnel to monitor, or areas to monitor.

[0123] (3) The input unit 35 receives instructions from the administrator when the administrator presses the automatic switching button BT1, which is displayed on the display unit 34 and can be pressed. By providing the automatic switching button BT1, which can be operated by the administrator, on the display unit 34, the administrator can stop the automatic switching of the display mode by simple operation as needed.

[0124] (4) The input unit 35 receives an instruction from the manager when the manager selects one of the multiple map display buttons BT61-BT63 corresponding to the multiple selectable delivery groups 1-3 displayed on the display unit 34. The display mode switching unit 204 switches the display mode to display the delivery group selected by the manager. The display control unit 203 stops the display mode switching implemented by the display mode switching unit 204 according to the instruction received by the input unit 35.

[0125] This allows administrators to quickly switch the display mode for each delivery group they want to monitor with a simple operation. Furthermore, the automatic switching of display modes stops when the administrator switches modes based on their actions, thus preventing automatic changes to the display of the delivery groups the administrator is monitoring, and providing a visual display that aligns with the administrator's intentions.

[0126] (5) The map image MAP is displayed on the display unit 34 in a manner that allows for changes in scale and location. The input unit 35 receives instructions from the administrator when the map image MAP is operated by the administrator. The display control unit 203 stops the switching of display modes performed by the display mode switching unit 204 based on the instructions received by the input unit 35.

[0127] When the scale or location of a map image is changed by the administrator, the automatic switching of the display mode stops. Therefore, the display of the map that the administrator is interested in will not be automatically switched, and the screen display can be provided in accordance with the administrator's intention.

[0128] (6) When the display mode is switched to the first to third group display modes by the display mode switching unit 204, the display control unit 203 controls the display unit 34 to display the location icons PI of all delivery personnel belonging to the delivery groups 1 to 3 in real time, whose location information has been obtained by the location information acquisition unit 202.

[0129] Therefore, even in, for example, Figure 7B Even when delivery personnel within the same delivery group are dispersed, the system automatically displays the current location of all logged-in delivery personnel within the same group, thus reliably monitoring the status of each delivery group. For example, if a delivery person moves to a location different from usual, the map scale and display location will change accordingly, making it easy to identify situations that are different from usual.

[0130] (7) The display mode switching unit 204 switches between multiple display modes at predetermined time intervals, including a full group display mode that simultaneously displays multiple delivery groups 1 to 3. This allows for the understanding of the positional relationships between delivery groups and the dynamics of each delivery person. Therefore, by observing the overall dynamics and then confirming the dynamics of a specific group, it is easy to grasp the condition of the delivery persons and to gain a more comprehensive understanding of their dynamics.

[0131] (8) When the display mode is switched to the first to third group display modes by the display mode switching unit 204, the display control unit 203 controls the display unit 34 to display the location icon PI of the delivery personnel located in the pre-set responsible area for each delivery group 1 to 3 in real time.

[0132] This allows for reliable monitoring of delivery personnel's activities within their assigned delivery groups' areas of responsibility. Specifically, the pre-assigned areas of responsibility for each delivery group are always displayed, making it easy to identify delivery groups from the map image. Furthermore, it allows for easy monitoring of the number and activities of delivery personnel within desired areas.

[0133] (9) The dynamic display device 5 also includes a loitering determination unit 205, which determines, based on the location information obtained by the location information acquisition unit 202, whether the delivery person is in a loitering state where they have stayed within a specified range for a specified time or more. Figure 3 The display control unit 203 controls the display unit 34 to display the location icon PI of the delivery person determined by the delay determination unit 205 to be in a delayed state in a manner that can be identified relative to the location icon PI of other delivery persons, or to display a delay warning image that warns the delivery person determined by the delay determination unit 205 to be in a delayed state.

[0134] By displaying in a recognizable manner the status of each delivery person remaining in one place beyond the intended delivery time, abnormal situations such as malfunctions during delivery can be detected in advance.

[0135] (10) The dynamic display device 5 also includes a non-communication determination unit 206, which determines whether the delivery person is in a non-communication state where location information cannot be obtained by the location information acquisition unit 202 for more than a specified time. Figure 3 The display control unit 203 controls the display unit 34 to display the location icons PI of delivery personnel that are determined by the non-communication determination unit 206 to be in a non-communication state in a manner that can be recognized relative to the location icons PI of other delivery personnel. This allows for the early detection of malfunctions in delivery personnel terminals 1A and 1B.

[0136] Furthermore, the above-described embodiments can be modified in various ways. The following describes some modifications. In the above-described embodiments, an example was given where the dynamic display device 5 displays the activities of delivery personnel performing delivery operations in real time. However, the dynamic display device can be in any form as long as it displays the current positions of multiple display objects belonging to any one of multiple groups in real time. For example, the activities of attendees at a large facility can also be displayed in real time according to each group of attendees or each area where they are staying.

[0137] In the above embodiment, the location information acquisition unit 202 acquires the location information calculated on the delivery terminal 1A and 1B sides, but the configuration of the location information acquisition unit that acquires the location information of the displayed object is not limited to this. For example, the location can also be calculated by the management server 2 based on GPS signals received on the delivery terminal 1A and 1B sides.

[0138] In the above embodiment, instructions from the user acting as the administrator are received via a touch panel, mouse, or the like on the display unit 34 of the administrator terminal 3. However, the instruction receiving unit for receiving instructions from the user is not limited to this form. For example, a microphone can be provided on the administrator terminal 3 to receive voice instructions from the user, and a camera can be provided on the administrator terminal 3 to receive gesture instructions from the user.

[0139] In the above embodiment, the display control unit 203 of the management server 2 controls the display unit 34 of the manager terminal 3, but the display control unit controlling the display unit is not limited to this. That is, the display control unit 301 of the manager terminal 3 can also generate, for example... Figure 4 , Figure 5 , Figures 7A-8 That kind of screen displays the DP image signal.

[0140] The present invention has been described above as a dynamic display device 5, but it can also be used as a dynamic display method for real-time display of the current positions of multiple display objects belonging to any one of multiple groups. That is, the dynamic display method includes: obtaining the location information of each of the multiple delivery personnel (…). Figure 9 Steps S3 and S4); Based on the obtained location information, control the display unit 34 to display the location icon PI representing the current location P of the delivery person on the map image MAP in real time (steps S5 and S6); Switch between multiple display modes at predetermined time intervals, including the first to third group display modes that display the location icons PI of delivery persons belonging to delivery groups 1 to 3 in real time (steps S1 and S2).

[0141] The dynamic display program is stored in the storage unit 21 of the management server 2, but it can also be stored on an external storage medium such as flash memory. The dynamic display program can also be obtained from outside the dynamic display system 100 via the network 4.

[0142] The above description is essentially an example, and the above embodiments and modifications do not limit the invention as long as they do not destroy its features. One or more of the above embodiments and modifications can be combined in any way, and modifications can also be combined with each other.
