Description

  The present invention displays position information of vehicles, ships, airplanes, etc. (collectively referred to as “moving bodies”) together with information on a map (including charts), and others relating to the operation of moving bodies according to user requests. It is related with the moving body operation information system which provides the information of.

  In particular, according to the present invention, it is possible to operate an object in an arbitrary lower layer without changing the order of layers on a computer screen in which the above-described various types of information are described in a plurality of layers and displayed in an overlapping manner. The present invention relates to a mobile operation information system. Note that “object” refers to a moving object or information displayed on a computer screen, and “object operation” refers to displaying or updating object related information. “Displaying related information of an object” includes displaying other predetermined information related to the object and displaying past information of the object itself such as the trajectory of the moving object.

  Conventionally, as a computer display method, there has been known a method of displaying overlapping images by stacking layers.

  The operation system (OS) of Microsoft (registered trademark) employs a display method in which a plurality of windows are displayed in a superimposed manner so that windows below can be seen through. This is also one of display methods by layer stacking.

  Also, in the CAD field, for example, in building design drawings, concrete foundation drawings, wood floor drawings, electrical wiring diagrams, piping diagrams, etc. are described in separate layers, and displayed and output in the necessary combinations. Things are known.

  On the other hand, there has also been a map information system. A map information system is a system that displays a map on a computer screen and displays related information by placing a cursor at a predetermined location, and is used in various fields. For example, in the field of car navigation systems, a map information system combined with layer display technology is known. In such a car navigation system, a map is described in one layer, and other information such as a parking lot location, a convenience store location, a gas station location is described in a separate layer, and is displayed by a user input command. There is known a technique of controlling a layer to be displayed and combining and displaying a parking lot position, a convenience store position, and a gas station position on a map as necessary.

  In a car navigation system, a technique is known in which a car serves as a cursor on a computer screen, and when a car reaches a predetermined location, information input in advance at that location is displayed.

  The map information system is also applied to navigation charts, ship and aircraft operation monitoring systems.

  Ship and aircraft operation monitoring systems include maps and charts, the position of moving objects, radar images, etc., on separate layers, which are superimposed on each other and displayed on a computer screen. A technique for providing necessary information is known.

(1) In the conventional map information system, the ground color of the layer is transparent, but the object itself is opaque so that it can be seen, and the objects overlap and are displayed in context. was there. When an object is displayed in a superimposed manner, conventionally, if an object to be operated is in a lower layer, the layer is raised to a surface layer and an operation is performed on a desired object.

  In other words, in the conventional layer display method, in order to operate a specific object, it is necessary to “activate” the layer to which the object belongs, and the order of the layers of the layer is switched by the activation of this layer. The state has changed.

  However, by enabling the display order of the layers to be changed, the position of the ship or aircraft that should always be monitored in the ship or aircraft operation monitoring system may become a lower layer. This is not preferable for safety of operation, and it is necessary to return to the default display state.

  For example, in an operation monitoring system for a ship or an aircraft, an object such as an approaching moving body, shallow water, or operation regulation is displayed in a superimposed state. In the part where the objects overlap, at least a part of one object is displayed in a state hidden behind another object.

  In a state where such objects overlap, it is necessary to operate the lower layer object without changing the order of the layers while displaying the position of the most important moving body on the surface.

  For this reason, one problem to be solved by the present invention is that a moving object operation information system that can operate an object in an arbitrary lower layer without changing the order of the layers on the screen displayed by overlapping the layers. Is to provide.

(2) In the operation information system of a ship or an aircraft, it may be necessary to know the past locus of a specific ship or aircraft while displaying the current position of the ship or aircraft.

  The conventional map information system can only know peripheral information at the current cursor position, and cannot know past time-series information of a specific object.

  When displaying past information, the positions of all moving objects at a certain point in the past are usually displayed.

  However, in operation information systems such as ships and airplanes, displaying the position of all moving objects at a certain point in time in the past may cause the information to be buried. Only the object needs to display past information in time series.

  Therefore, another problem to be solved by the present invention is that, in the operation information system of a moving object, when a cursor such as a mouse is placed on a specific moving object and clicked, the past locus of the moving object in the present situation The object is to provide a mobile operation information system capable of displaying time-series information.

(3) Also, when displaying time-series information such as the trajectory of the moving object on the screen, in consideration of ordinary techniques, information such as the past trajectory of each moving object is recorded in the database, and a specific moving object is recorded. When is selected, the past data of the mobile object is searched from the database, and the past data of the searched mobile object is drawn on the current screen.

  However, both the search for the database and the drawing of the past data on the screen are time consuming processes, which causes a problem that the process is slow.

  Therefore, another problem to be solved by the present invention is that in a travel information system of a moving body, when a mouse cursor is clicked on a specific moving body and clicked, time series information such as the past trajectory of the moving body is extremely reduced. The object is to provide a mobile operation information system that can be displayed in a short time.

The mobile operation information system of the present invention is
A screen display unit for displaying a plurality of layers displaying screen data in a predetermined order on a computer screen;
Determines which part of each layer is managed as an object, gives identification information for each object, manages object position information at a predetermined time, and commands when the cursor is at a predetermined coordinate Is issued, the command transparency control of the object that controls whether or not the object that aligns with the coordinates executes the command, and whether or not the entire layer is displayed by controlling the transparency of the layer A layer control unit that performs display control to be controlled;
An information database for storing information held by the object;
An input means capable of controlling a cursor on a computer screen and inputting a command;
A central processing unit for controlling the entire process,
The central processing unit causes the layer control unit to set command transparency of each layer object and transparency of each layer in response to a command from the user via the input unit, and causes the screen display unit to perform the layer control. Each layer set by the part is displayed on the overlapping computer screen,
When the user inputs a predetermined command by positioning the cursor at a predetermined coordinate on the computer screen by the input means, the central processing unit moves the object of each layer aligned with the coordinates of the cursor from the surface layer to the lower layer. The information is retrieved from the information database by executing the command on the object in the uppermost layer among the objects set to execute the command by searching toward the layer of the object, aligning with the coordinates of the cursor, and executing the command. And a layer control command for display is output to the layer control unit as necessary, and the layer and necessary information are displayed in a superimposed manner on the screen display unit.

The layer that displays the position of the moving object is a layer group having a predetermined number of layers in time series. In a normal use state, the central processing unit and the layer control unit only apply the layer at the latest moving object position. Control the display so that the layer of the past moving body position is transparent, and the layer group of the moving body position is overlapped and displayed on the screen display unit,
When a cursor is aligned with a predetermined moving body and a past data reference command for requesting reference to past data is input, the central processing unit executes the command to obtain identification information of the moving body, Based on the identification information of the moving object, the layer control unit displays only the moving object having the same identification information among the moving objects on the layer at the past moving object position, and the layer group of the moving object position is displayed on the screen display unit. Can be displayed in an overlapping manner.

  In an image displayed by overlaying layers of the moving body position, the moving body having the same identification information is connected by a line to display trajectory information, or the moving body having the same identification information as necessary. Can be highlighted.

The layer that displays objects having time-series data including meteorological information and communication between moving objects is a layer group having a predetermined number of layers in time series, and in a normal use state, the central processing unit and the layer The control unit controls to display only the latest layer, and the layer that displays past time-series data displays the entire layer as a transparent layer on the screen display unit,
When a cursor is aligned with a predetermined object and a past data reference command for requesting reference to past data is input, the central processing unit executes the command to acquire identification information of the object, A layer that displays only objects having the same identification information among objects on the past time-series data layer on the layer control unit according to the object identification information, and displays the object having the time-series data on the screen display unit Groups can be displayed in an overlapping manner.

  The upper layer has a layer that describes the position of the moving object, and the lower layer has a layer that describes the map. Between that, the AIS layer that describes the communication data between the moving objects, the satellite photo layer, the radar image layer, and the weather data It has at least one of the described weather layers and can have a layer control interface that allows the user to select which layer of objects can be manipulated or which layer to display.

  In the mobile operation information system of the present invention, a plurality of layers in which screen data including objects are displayed are stacked in a predetermined order and displayed on a computer screen. A predetermined part or range of each layer is managed by identification information as an object, and when a command is issued when the cursor is at a predetermined coordinate, whether or not the object aligned with the coordinate executes the command is determined. It is preset for each layer.

  When the user places a cursor on a computer screen at a predetermined coordinate and inputs a predetermined command, the central processing unit searches the object of each layer that aligns with the cursor coordinate from the surface layer to the layer below. Then, the command is executed on the object in the uppermost layer among the objects set to be aligned with the coordinates of the cursor and to execute the command.

  Thus, the moving body operation information system of the present invention does not change the order of the layers, and the command is applied to the lower layer object set to execute the command among the objects displayed to overlap each other. Can be executed.

  The execution setting of the above command, that is, command transparency can be freely set for each layer, so that an object in an arbitrary layer below can be operated.

  Also, when executing a command on objects that are displayed to overlap each other in this way, the layer does not change, so an important moving object It is possible to reduce the risk that the current position of the lower layer becomes the lower layer and the eyes of the monitoring are out of reach.

  In another aspect of the present invention, layers for displaying an object having time series data are displayed as a layer group having a predetermined number of layers in time series.

  As for the position of the moving object, the layer in which the current and past positions of the moving object are recorded can have a predetermined number of layers in time series, and only the layer of the latest moving object position is displayed. By controlling so that the layer of the past moving body position is made transparent so that the entire layer is transparent, the latest moving body position can be displayed in a normal use state. .

  In such a state, when the cursor is aligned with a predetermined moving body and a reference to past data is requested, in the present invention, the central processing unit executes the command to acquire the identification information of the moving body. Using the identification information as a key, control is performed so that only the moving bodies having the same identification information are identified and displayed among the moving bodies on the layer of the past moving body position. Overlapping display.

  In this way, past information of a moving object having specific identification information is displayed, so that when the layer group of moving object positions is displayed in an overlapping manner, the current position of another moving object is displayed, The past trajectory of the moving object is displayed.

  According to the invention having a function of connecting a moving body having the same identification information with a line and a function of highlighting the same identification information, the trajectory information of the moving body is displayed in an easy-to-understand manner.

  An object having the above time-series data can also be applied to an object having weather information. In a mobile operation information system that displays information on multiple anemometers / anemometers, past data on anemometers / anemometers Recording to multiple layers in series, and if the user moves the cursor to a specific wind direction / anemometer and enters a past data reference command, the process of the change of wind direction / wind speed at the wind direction / anemometer point can be checked at a glance can do.

  An object having time series data can also be applied to communication data between mobile objects. In this case, communication data between specific mobile objects can be expressed in time series, Is much easier to understand.

  The object having the time series data is not limited to the moving body position, weather information, communication data, and the like, and can be applied to an object having arbitrary time series data.

  As described above, in the present invention, a layer having time-series data is originally included as a component of screen display, and when there is a request for referring to past data, only a specific object is revealed. In the current information screen, past data of a specific object can be continuously displayed.

  For this reason, as in the prior art, when past data is stored in a database and a past data reference command for a predetermined object is input, the time for searching the past data of the object or the current screen is searched. The time for drawing past data is omitted, and the past data of a specific object can be displayed very quickly.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. The invention of the present application is not limited to a ship, but relates to a system that widely provides operation information of a moving body including a ship, an aircraft, and a vehicle. For the sake of easy understanding, the following description will be made by taking a ship operation information system as an example. .

  FIG. 1: has shown the block diagram by one Embodiment of the mobile body operation information system which concerns on this invention. As shown in the figure, the ship operation information system 1 of the present invention includes a central processing unit 2, a layer control unit 3, a screen display unit 4, an information database 5, and input means 6.

  The central processing unit 2 is a part that controls the overall processing.

  The screen display unit 4 is a part that displays a plurality of layers on which screen data is displayed in a predetermined order on a computer screen.

As shown in FIG. 1, a layer has a plurality of layers, and each layer is an element that forms a screen. Each layer has objects O ₁ , O ₂ , O ₃ , O ₄ ... Having information on a transparent surface, and image data having no information, for example, satellite data or image data representing a wide sea area. ing. The ground color of the layer is transparent in principle. An object can be defined as a closed fixed graphic area, is related to information, and can refer to or update related information. The objects O ₁ , O ₂ , and O ₃ are defined as triangular graphic areas, and can be defined as indicating a ship, for example. Each object has identification information. Objects of each layer are managed by the layer control unit based on the identification information.

  Each layer describes specific types of information for easy management. For example, ship data, communication data between moving bodies, radar images, weather data, and map data are described in separate layers.

  Furthermore, an object having time-series information, for example, a layer describing ship data, has a plurality of layers having the same kind of information, and forms a layer group.

  When the layers are displayed in an overlapping manner, since the ground color of each layer is transparent, only the image on each layer is displayed in a superimposed manner to form one screen.

  The layer control unit 3 determines which part of each layer is managed as an object, gives identification information for each object, and manages the position information of each object at a predetermined time for a moving object. This control is called object control.

  In addition, when a command is issued when the cursor is at a predetermined coordinate, the layer control unit 3 controls whether or not an object whose position is aligned with the coordinate executes the command. This control is called object command transparency control.

  Further, the layer control unit 3 controls the presence / absence of display of the entire predetermined layer by controlling the transparency of each layer. This control is called display control.

  The information database 5 stores information related to each object using object identification information as a key.

  The information database 5 stores image data of layers that do not always need to be displayed and image data of layers that exceed the upper limit of the number of layers.

  The input means 6 forms an interface between the user and the ship operation information system 1 and preferably includes means for operating at least a cursor so that a command can be input to the ship operation information system 1.

  In addition, although not shown in figure, the ship operation information system 1 has a memory | storage device and an output device as needed.

  Further, the ship operation information system 1 can be configured as a stand-alone device or can be configured as a system on a network.

  FIG. 2 is a diagram illustrating display control based on command transparency control of an object and transparency control of a layer.

In the example of FIG. 2, there are three layers L ₁ , L ₂ , and L ₃ , and the layer L ₁ has only image data having no information. Layer L ₂ has objects O _X and O _Y , and layer L ₃ has object O _Z. Object O _Y and object O _Z is assumed to overlap when viewed from above.

The layer L ₁ may be set such that all of the image data including the image data cannot be seen by setting the transparency to 100%, or the image data can be seen by setting the transparency to less than 100%. You may do it.

  Even if image data that is not an object is visible, it does not respond to commands.

The layer L ₂ includes objects O _X and O _Y , the object O _X is set so as not to be transparent to the command, and the object O _Y is set to be transparent to the command. Shall.

Layer L ₃ has an object O _Z, the object O _Z assumed to be set so as not to have a transparent to the command.

  “Command is transparent” for a given object means that no command is executed for the object even if the command is requested when the cursor is in the graphic area of the object. The command transparency of an object may be set uniformly for the entire layer, or the command transparency may be individually set by specifying an object on a predetermined layer.

In Figure 2, when the cursor is in the graphic area of the object O _X when viewed from above, the command is requested, the layer L ₁ does not react to a command, the object O _X layer L ₂ of the lower layer because it is set so as not to have a command permeability, to execute commands on the object O _X on demand.

On the other hand, when the cursor is in the overlapping portion of the object O _Y and O _Z when viewed from above, the command is requested, the layer L ₁ does not react to the command, the lower layer L ₂ object O _Y because not react in the same manner as the command because it is set to have a command permeability, further objects O _Z layer L ₃ thereunder is set so as not to have a command permeability, on demand executing commands on the object O _Z Te.

At this time, to manipulate the object _{O Z,} the order of the context of the layer _{L 1,} L 2, _{L 3} is not changed, while overlapping of the object _{O Y} and _{O Z,} with respect to the underlying object _{O Z} Command can be executed.

  FIG. 3 shows a screen display example when the mobile operation information system of the present invention is applied to a ship operation information system.

  In FIG. 3, reference numeral 7 indicates a coastline, reference numeral 8 indicates a line with a depth of 10 meters, reference numeral 9 indicates a line with a depth of 30 meters, and map data (including chart data) is indicated by lines 7, 8, and 9. Is configured.

  Reference numeral 10 indicates weather data that graphically represents the wind direction and the wind speed.

  The code | symbol 11 has shown AIS data containing the presence of the communication between ships, the direction of transmission / reception, and the message content.

  Reference numeral 12 denotes a ship. In addition, a ship is represented as a triangular object, and in FIG. 3, all triangles indicate objects of the ship, and only a few ships are denoted by reference numeral 12 for ease of viewing.

  FIG. 4 is an exploded view of the layer structure corresponding to the screen of FIG.

  As shown in FIG. 4, the screen of FIG. 3 has a map layer, a weather layer, a radar / satellite image layer, an AIS data layer, and a ship data layer from the bottom.

  In the ship operation information system, as shown in FIG. 4, the map layer is in the lower layer, the ship data layer is in the upper layer, and in the meantime, the AIS layer in which the communication data between the moving objects is described, the satellite photograph layer, Preferably, a radar image layer and a weather layer describing weather data are arranged.

  With such a context, the current ship position, which is the most important for the ship operation information system, is always displayed, and the risk of the ship position not being visible due to lower object operations can be avoided.

  As for the map layer, a coast line, a line with a depth of 10 meters, and a line with a depth of 30 meters are described in each layer, and the map layer is configured as a whole.

  The meteorological data has time-series information, the meteorological data at time 0, the meteorological data at time-1 and the meteorological data at time-2 are described in each layer, and the meteorological layer is composed of these layers. ing.

  Normally, only the meteorological data layer at the current time 0 is displayed as the weather layer, and the past meteorological data layer is set to be transparent by display control and is not displayed.

  Radar images and satellite images can be displayed as necessary by forming a radar / satellite image layer.

  The AIS data layer describes the existence of communication between ships, the direction of transmission / reception, and message contents, and has time-series information. In FIG. 4, only one layer is shown for convenience. You may be comprised by the layer group which consists of these layers.

  The ship data layer indicates the position of the ship in the area, has time-series information, ship data at time 0, ship data at time -1, ship data at time -2, and ship data at time -3. It has ship data and ship data at time -4, and the ship data layer is composed of a layer group composed of a plurality of layers describing them.

  Only the ship data layer at the current time 0 is normally displayed as the ship data layer, and the past ship data layer is set to be transparent by display control and is not displayed.

  A screen as shown in FIG. 3 is formed by displaying each layer of FIG. 4 in an overlapping manner.

  Next, the usage method and processing of the moving body operation information system according to the present invention will be described below.

  FIG. 5 shows a screen of a mobile operation information system having a layer control interface that allows the user to select which layer object is operable or which layer is displayed.

  As shown in FIG. 5, in this embodiment, a button 13 capable of selecting a layer of an object that can be operated and a layer to be displayed can be selected in the upper left portion of the computer screen displaying the screen of FIG. A user interface having buttons 14 is provided.

  The user designates a layer for performing an object operation and a layer to be displayed through the input means 6 through the user interfaces 13 and 14 in FIG.

  The central processing unit 2 of this system causes the layer control unit 3 to set the command transparency of each layer object and the transparency of each layer in response to a command input by the user via the input means 6, and then the screen The display unit 4 displays each layer set by the layer control unit 3 on a superimposed computer screen.

  In this manner, only the layer to be displayed can be selected and displayed by operating the user interfaces 13 and 14. In addition, an arbitrary layer capable of manipulating an object is selected, and an object displayed in an overlapping manner as described with reference to FIG. The object can be manipulated.

  According to the present invention, the user can operate an object in a layer of an arbitrary layer, click on an object in a lower layer with respect to an overlapping object, and display information related to the object. Can be requested. In response to such information display request, the central processing unit 2 acquires the identification information of the object for which the command is executed, searches the information database 5 for information related to the identification information, and displays the screen display unit 4. To be displayed on the computer screen.

  Finally, a method for displaying the time series information of the object will be described below.

  FIG. 6 is a diagram for explaining a method of displaying a ship trajectory as time-series information of objects.

  In FIG. 6, only the layer group of the ship data layer and the map data layer are shown for easy understanding, but there may actually be other layers.

  In the example of FIG. 6, a ship data layer at time 0, a ship data layer at time −1, a ship data layer at time −2, a ship data layer at time −3, and a ship data layer at time −4. In general, only the ship data layer at time 0 indicating the current ship position is displayed.

  If it is desired to obtain past time-series information of a ship (identification information is S1) at the current ship position, the user places the cursor on the object of the ship S1 and requests the past data to be referred to. Enter a reference command.

  The central processing unit 2 recognizes a past data reference command, searches for an object of each layer that aligns with the coordinates of the cursor from the surface layer toward the lower layer, aligns with the coordinates of the cursor, and executes the command The command is executed on the object in the uppermost layer among the objects set to be.

  In the example of FIG. 6, since the object S1 of the uppermost layer does not transmit the command, the past data reference command is executed for the object S1 of the current uppermost ship data layer.

  When the command is a “past data reference command”, the central processing unit 2 acquires the identification information S1 of the mobile object on which the command is executed, and as shown in FIG. Among the ships on the ship data layer, a ship having the same identification information S <b> 1 is specified and controlled so as to be displayed by controlling the transparency, and the ship data layer group is displayed on the screen display unit 4 in an overlapping manner.

  In FIG. 6, the ship data layers have five overlapping layers, but the number of layers depends on the processing capability of the computer, and a large number of ship data layers can be displayed. However, since the screen cannot be displayed in an infinitely large number of ship data layers, the past data layers of a certain number of layers or more are stored in the information database 5.

  If you want to display past data that exceeds the number of layers that exist as elements that make up the screen, extract the necessary past layers from the information database 5, perform the same processing as above, Display time series information.

  FIG. 7 is a diagram showing past position information of a predetermined ship as a trajectory by the above processing.

  As shown in FIG. 7, a plurality of ships for displaying past data may be displayed. Further, as shown in FIG. 7, in the image displayed by overlaying the layer group of ship positions, the ship having the same identification information is connected by a line to display the trajectory information, or the same identification information as necessary. A moving object having can be highlighted.

  Thereby, the trajectory information becomes clear.

  Further, as can be seen from FIG. 7, only the ship requested for the past data reference command shows the trajectory information, and the other ship shows only the current position, so the screen is simple and the trajectory of the specific ship Can be understood clearly and clearly.

  6 and 7 describe the case of displaying time-series position information of a specific ship. However, the present invention is not limited to the time-series position information of a ship, and can be applied to, for example, an object having weather information. In a mobile operation information system that displays information on at least one wind direction / anemometer, the past data of the wind direction / anemometer is recorded in multiple layers in time series, and the user can select a specific wind direction / If you move the cursor to the anemometer and enter a past data reference command, you can see at a glance the process of changes in the wind direction and wind speed measured by a specific wind direction and anemometer.

  In addition, it can be applied to communication data between mobile units. By specifying communication data between specific mobile units, past communication contents can be represented in time series, greatly understanding the communication contents. To be easier.

  As is apparent from the description of FIGS. 6 and 7, according to the present invention, when the past data of a specific object is to be displayed, if the number of screen layers is sufficient, information on the object is retrieved from the information database. There is no need to draw.

  That is, according to the present invention, a layer having time-series data is provided as a constituent element of the screen display, and when there is a request for referring to past data, the target object of each layer is simply revealed. The past data of the target object can be continuously displayed in the information screen.

  Thereby, the process of searching the past data of a specific object and drawing of the searched past data can be omitted, and the past data of an arbitrary object can be displayed quickly.

A moving body operation information system characterized by displaying two or more images.   The moving body operation information system according to claim 1, wherein in the image displayed by overlapping the moving body position layer group, the moving body having the same identification information is connected by a line to display trajectory information. A screen display unit for displaying a plurality of layers displaying screen data in a predetermined order on a computer screen;
Determines which part of each layer is managed as an object, gives identification information for each object, manages object position information at a predetermined time, and commands when the cursor is at a predetermined coordinate Is issued, the command transparency control of the object that controls whether or not the object that aligns with the coordinates executes the command, and whether or not the entire layer is displayed by controlling the transparency of the layer A layer control unit that performs display control to be controlled;
An information database for storing information held by the object;
An input means capable of controlling a cursor on a computer screen and inputting a command;
A central processing unit for controlling the entire process,
The central processing unit causes the layer control unit to set command transparency of each layer object and transparency of each layer in response to a command from the user via the input unit, and causes the screen display unit to configure the layer Overlay each layer set by the control unit and display it on the computer screen,
When the user inputs a predetermined command by positioning the cursor at a predetermined coordinate on the computer screen by the input means, the central processing unit moves the object of each layer aligned with the coordinates of the cursor from the surface layer to the lower layer. The information is retrieved from the information database by executing the command on the object in the uppermost layer among the objects set to execute the command by searching toward the layer of the object, aligning with the coordinates of the cursor, and executing the command. And, if necessary, output a layer control instruction for display to the layer control unit, and display the layer and necessary information on the screen display unit,
A layer control interface that allows the user to select which layer of objects can be manipulated;
The layer that displays objects having time-series data including meteorological information and communication between moving objects is a layer group having a predetermined number of layers in time series, and in a normal use state, the central processing unit and the layer The control unit controls to display only the latest layer, and the layer that displays past time-series data displays the entire layer as a transparent layer on the screen display unit,
When a cursor is aligned with a predetermined object and a past data reference command for requesting reference to past data is input, the central processing unit executes the command to acquire identification information of the object, A layer that displays only objects having the same identification information among objects on the past time-series data layer on the layer control unit according to the object identification information, and displays the object having the time-series data on the screen display unit A mobile operation information system characterized by displaying a group superimposed.
