  Next, the best embodiment according to the present invention will be given and described in detail with reference to the drawings.

  First, the configuration of the management system 1 that can implement the mobile object information display method according to the present embodiment will be described with reference to FIGS.

  FIG. 2 is a block diagram showing the entire management system 1. The management system 1 includes a managed device 20 mounted on a moving body and a management device 30 installed at another location separated from the moving body. In this case, as an example, a transport truck or the like can be assumed as the moving body, and a management center or the like at the terminal of the transport truck can be assumed as another place away from the mobile body.

  The managed device 20 includes a computer unit 21.

The communication unit 21t performs bidirectional communication with the display panel 21d and the management device 30 side. The computer unit 21 is configured as a dedicated device that can be mounted on a moving body.

  Further, a GPS receiver 5 is mounted, and this GPS receiver 5 is connected to the control unit 21c. The GPS receiver 5 has a basic function of receiving radio wave signals (GPS signals) transmitted from a plurality of GPS satellites 50 and recognizing current position information Ax related to the current position of the moving body. In this case, the GPS receiver 5 can obtain time information A1, latitude information A2, longitude information A3, altitude information A4, speed information A5, and direction information A6 shown in FIG. Current position information Ax can be obtained from the longitude information A3. On the other hand, reference numeral 23 denotes a sensor unit (G sensor), from which acceleration information A7 and angular velocity information A8 shown in FIG. 3 can be obtained. Reference numeral 24 denotes a moving body information acquisition unit. The moving body information acquisition unit 24 is information that is basically owned by the moving body itself, and includes information that can be acquired without separately providing a sensor or the like. Therefore, from the moving body information acquisition unit 24, speed information A9, engine speed information A10, travel distance information A11, fuel consumption information A12, light operation information A13, foot brake operation information A14, seat belt attachment / detachment shown in FIG. Operation information A15, parking brake operation information A16, turn indicator operation information A17, shift operation information A18, air conditioner operation information A19, and car audio operation information A20 can be obtained. The sensor unit 23 and the moving body information acquisition unit 24 constitute predetermined information acquisition means 6 provided in the moving body, and each information related to A1 to A20 can be obtained by the information acquisition means 6. This is moving body information other than the current position information Ax. Since the mobile body information can include various types of information A1,..., Various states related to the mobile body can be displayed according to the situation judgment of the administrator (operator) as necessary.

The computer system 3 includes a control unit 3c including a CPU and the like, a main part of a computer having a memory 3m including a RAM and a ROM, a display 3d such as a color liquid crystal display, and a keyboard. And a communication unit 3t that performs bidirectional communication with the operation unit 3s such as a mouse and the communication unit 21t of the managed device 20. Therefore, the communication unit 21t of the managed device 20 and the communication unit 3t of the management device 30 constitute a predetermined communication unit 7 that transmits at least the current position information Ax and each information A1 acquired in the moving body to the computer system 3. . Note that necessary data and commands (voices) can be transmitted from the management apparatus 30 side to the managed apparatus 20 side by bidirectional communication. The computer system 3 can use a general-purpose personal computer, and in particular, installs and uses a processing program (application program) that can execute the mobile information display method according to the present invention.

  Reference numeral 4 denotes data storage means. This data storage means 4 may be an internal memory (memory 3m) of the computer system 3 or an external memory registered in a medium from the viewpoint of hardware, and constitutes a database from the viewpoint of software. That is, the data storage means 4 constitutes a database related to the map data Dm and a database related to the graphic data Df. In this case, the map data Dm can display the map M on the screen Vd of the display 3d as shown in FIG. 1 (FIG. 4).

  On the other hand, the graphic data Df is a graphic whose size is changed at least in correspondence with the state of each information A1, A2,..., And FIG. 1 shows a display mode of the speed information A5 (including A9). In this case, the ring graphic F1 is used as the graphic data Df. The ring figure F1 changes the size of the diameter according to the state of the speed information A5. For example, the diameter is reduced at a low speed, and the diameter is increased at a high speed. Therefore, icons (graphic data Df) of a plurality of ring figures F1... Having different diameters corresponding to a plurality of different speed sizes are preset (registered) as a database. Also, graphic data Df related to the graphic W imitating a clock is registered. Thereby, the time corresponding to the time information A1 can be displayed using the figure W. Such graphic data Df can be set in various modes, and the speed information A5 can also be set by a line graphic F2 (see FIG. 4) as in a modified embodiment described later. Furthermore, although only speed information A5 and time information A1 are illustrated, other information A2 to A4, A6 to A8, and A10 to A20 are set in the same manner as shown in a part of the modified embodiment described later. be able to.

  Next, the display method of the mobile body information which concerns on this embodiment including the usage method and function of the management system 1 comprised in this way is demonstrated with reference to FIGS.

  First, when the moving body moves (regardless of whether it is actually moving or stopped), the managed device 20 mounted on the moving body uses the GPS receiver 5 to obtain current position information Ax related to the current position of the moving body. recognize. Further, various pieces of mobile body information other than the current position information Ax are acquired by the information acquisition means 6 provided in the mobile body. That is, the GPS receiver 5 obtains time information A1, latitude information A2, longitude information A3, sea level altitude information A4, speed information A5, and azimuth information A6, and the sensor unit 23 obtains acceleration information A7 and angular velocity information A8. Further, the speed information A9, the engine speed information A10, the travel distance information A11, the fuel consumption information A12, the light operation information A13, the foot brake operation information A14, and the seat belt attachment / detachment operation information are obtained by the moving body information acquisition unit 24. A15, parking brake operation information A16, turn indicator operation information A17, shift operation information A18, air conditioner operation information A19, and car audio operation information A20 are acquired. Then, the acquired current position information Ax and information A1, A2,... Other than the current position information Ax are transmitted from the communication unit 21t to the management apparatus 30 side.

  On the other hand, these pieces of information Ax, A1,... Transmitted from the communication unit 21t are received by the communication unit 3t of the management device 30. The management device 30 reads the map data Dm including the current position information Ax from the current position information Ax from the data storage means 4 and displays it on the display 3d. FIG. 1 (FIG. 4) shows a state in which a map M corresponding to the read map data Dm is displayed on the screen Vd of the display 3d. Note that the map M can be displayed in advance when the travel route of the moving body is known in advance, regardless of the acquisition of the current position information Ax.

  Further, the operator (administrator) can select the moving body information to be used from the received information Ax, A1,..., That is, the information A1 to be displayed on the map M, using the operation unit 3s. Assume that the operator has selected speed information A5. In this case, for the speed information A5, since the graphic data Df corresponding to the state (speed magnitude) of the speed information A5 is registered in the data storage means 4 as the ring graphic F1, the received speed information A5 The graphic data Df related to the ring graphic F1 having a diameter corresponding to the speed at is read from the data storage means 4 and displayed on the map M displayed on the screen Vd of the display 3d. At this time, the displayed position is a position corresponding to the current position information Ax. Similar display processing is performed at regular time intervals. Accordingly, ring figures F1,... With the same diameter or different diameters are sequentially and cumulatively displayed on the map M in accordance with the travel route of the moving body. This display mode is shown in an enlarged view in FIG. 1, and the entire display mode is indicated by a symbol Fc in FIG. In this way, when the ring figure F1 is used as the figure and the diameter is changed in accordance with the state of the speed information A5, for example, when the speed is high, the diameter of the circle figure F1 increases. Therefore, when the images are sequentially displayed in a cumulative manner, the width is widened, and the administrator can confirm the state at a glance. Therefore, this display mode is optimal for grasping the speed change and the like. In addition, when the ring figure F1 is used, there exists an advantage which can grasp | ascertain easily the space | interval (roughness) between a plurality of ring figures F1 ... when they overlap in a time series direction.

  Further, the graphic data Df related to the graphic W imitating the clock is read from the data storage means 4, and the time corresponding to the received time information A1 is set, and at predetermined intervals according to the travel route of the moving object on the map M. indicate. In the example, the hour and minute are displayed by the hour hand and the minute hand. As described above, if the time information A1 is sequentially displayed at predetermined intervals by a graphic W imitating a clock at a corresponding position on the map M displayed on the display 3d, the time can be easily and accurately grasped. There is an advantage that can be confirmed.

  Therefore, according to such a display method, the figure (F1...) Corresponding to the state of the mobile object information (A1, A2...) Is sequentially and cumulatively displayed on the map M of the display 3d at predetermined intervals. Therefore, it is possible to quickly grasp information necessary for the administrator. Therefore, for example, when an unfavorable running state is confirmed, such as overspeeding or turning a sharp handle, the state can be quickly grasped, and therefore monitoring can be performed with particular care. Moreover, since the figure (F1...) Corresponding to the state of each moving body information (A1, A2...) Can be displayed in a mode with a larger amount of information, the traveling state of the moving body can be grasped more accurately and accurately. can do. Therefore, accurate and precise management as well as necessary situation analysis and comprehensive management can be sufficiently performed. In particular, in the above example, the computer system 3 including the display 3d is provided in another location separated from the moving body, and the current position information Ax and the moving body information (A1...) Acquired in the moving body are predetermined from the moving body. Since the communication means 7 transmits the data to the computer system 3, there is an advantage that centralized management of a plurality of mobile objects can be performed in a management center or the like.

  Next, the display method of the mobile body information according to the modified embodiment of the present invention will be described with reference to FIGS.

  FIG. 4 shows a display mode in which a linear figure (line figure) F2 is used as the figure in the figure data Df, and the line length is changed in accordance with the state of the moving body information (A1...). Therefore, in the case of the exemplified speed information A5, the speed information is shortened at a low speed and is long at a high speed. Moreover, the line figure F2 can show the direction of a running direction by changing direction. For this reason, in actual display, the line figure F2 having a different length is displayed at an angle (direction) corresponding to the received azimuth information A6. For this reason, in this example, icons of a plurality of line figures F2,... Having different lengths corresponding to a plurality of different speed sizes, that is, figure data Df are preset (registered) as a database.

  Using the graphic data Df of such a line graphic F2, as shown in FIG. 4, the traveling direction of the moving body and the speed at that time are displayed simultaneously. That is, on the map M, line figures F2,... Having the same diameter or different lengths are sequentially and cumulatively displayed according to the travel route of the mobile object, and at the same time, the travel direction of the mobile object is the angle (direction) of the line figure F2. Is displayed. This display mode is shown in an enlarged view in FIG. 4, and the entire display mode is indicated by the symbol Fc in FIG. As described above, when the line figure F2 is used as the figure and the length of the line is changed in accordance with the state of the speed information A5, the traveling direction of the moving object and the time at that time can be obtained by using the direction information A6. Since the speed of the vehicle can be displayed simultaneously, for example, the traveling state of the moving body at the intersection can be confirmed at a glance. Therefore, this display mode is optimal for grasping the handle operation and the like.

  5 and 6 show other mobile information. FIG. 5 shows the simplest display mode, in which the movement elapsed time is displayed based on the time information A1. Therefore, the diameter of the ring figure F1 increases sequentially in proportion to the elapsed time of movement. In this case, it is possible to check at a glance the elapsed time of the Oma. FIG. 6 shows a mode in which acceleration information A7 or angular velocity information A8 is displayed. In this case, the size of the diameter of the ring figure F1 is displayed differently corresponding to the magnitude of acceleration or angular velocity. For example, when there is a sudden start or a sudden brake, or when shaking is large, the diameter of the ring figure F1 becomes large. 5 and 6, the same parts as those in FIG. 1 (FIG. 4) are denoted by the same reference numerals to clarify the configuration.

  In FIG. 7, a computer system 3 including a display 3d is provided in a moving body, and display based on the current position information Ax and the moving body information (A1...) Acquired in the moving body is performed on the moving body side. Therefore, the display 3d can use the relatively small display panel 21d shown in FIG. 2, and the computer system 3 can use the computer unit 21 shown in FIG. Thereby, since the driver | operator and passenger of a moving body can also confirm the state of a moving body, there exists an advantage which can be reflected in actual driving | operation etc. quickly by seeing the display content. The form of FIG. 7 may be used alone or in combination with the form of FIG. In other words, the management target device 20 shown in FIG. 2 may be replaced with the management target device 20 shown in FIG.
