The arrow 90a may indicate the magnitude of the velocity by the length thereof. In this case, when the ignition SW is off (IGN_OFF), the speed is the value 0, so the arrow is not displayed, and instead, a point is displayed. That is, the vehicle mark 90 is drawn in a circle having a center point.

  An operation of the management system 5 having the above configuration is shown. FIG. 6 is a sequence diagram showing an operation procedure of the management system 5. The vehicle-mounted device 10 constantly monitors on / off of the ignition switch 16 of the vehicle 3. Further, the on-vehicle device 10 can repeatedly acquire GPS position data based on the GPS signal received by the GPS receiving unit 15.

  The vehicle-mounted device 10 detects that the ignition switch 16 is on (ignition on) (T1). Further, when the vehicle-mounted device 10 detects that the ignition is on, the vehicle-mounted device 10 acquires GPS position data (T2). The vehicle-mounted device 10 transmits ignition on information and GPS position data to the server 30 together with the vehicle number and the operation data (total traveling distance, maximum speed while traveling, etc.) (T3).

  The server 30 updates the database 37z stored in the storage 37 based on the information transmitted from the vehicle-mounted device 10 (T4). The server 30 creates display data for the wide area operation status screen GM1 displayed on the display unit 33 of the server 30 and the display unit 53 of the user PC 50 based on the data registered in the updated database 37z (T5 ). When creating display data for the wide area operation status screen GM1, the server 30 creates a wide area circle graph 80 displayed so as to overlap a predetermined area on the map. Further, the wide-area circle graph to be created may be one in which the aforementioned attribute is reflected in accordance with information set in advance.

  The server 30 displays the wide-area operation status screen GM1 on the display unit 33 based on the created display data (T6). The server 30 determines whether there is a request for display data from the user PC 50 via the network 70 (T7). The request for display data of the user PC 50 may be a request for display data narrowed down by designating an attribute.

  When the server 30 receives a request for display data from the user PC 50, the server 30 sends display data of the wide-area operation status screen GM1 to the user PC 50 via the network 70 (T8).

  The user PC 50 displays the wide area operation status screen GM1 on the display unit 53 based on the display data of the wide area operation status screen GM1 transmitted from the server 30 (T9). The user performs a predetermined switching operation on the wide area operation status screen GM1 displayed on the display unit 53 by selecting the wide area circle graph 80 with the cursor kr (T10). When the user PC 50 receives this operation, it requests the server 30 for display data of the narrow area operation status screen GM2 corresponding to the selected wide area circle graph 80 (T11).

  When the server 30 receives a request for display data from the user PC 50, the server 30 creates display data for the narrow area operation status screen GM2 corresponding to the selected wide area circle graph 80 (T12). At this time, the server 30 may switch the screen displayed on the display unit 33 of the server 30 from the wide area operating status screen GM1 to the narrow area operating status screen GM2. The server 30 returns the display data for the created narrow area operation status screen GM2 to the user PC 50 (T13).

  Based on the display data for the narrow area operation status screen GM2 received from the server 30, the user PC 50 changes the display from the wide area operation status screen GM1 displayed on the display unit 53 to the narrow area operation status screen GM2. (T14).

  Thereafter, the vehicle-mounted device 10 detects that the ignition switch 16 is off (T15). Also, when the vehicle-mounted device 10 detects that the ignition is off, it acquires GPS position data (T16). The vehicle-mounted device 10 transmits ignition off information and GPS position data to the server 30 together with the vehicle number and the operation data (total traveling distance, maximum speed while traveling, etc.) (T17). The subsequent operation is the same as when the ignition is on.

  The server 30 updates the database 37z stored in the storage 37 based on the information transmitted from the vehicle-mounted device 10 (T18). The server 30 creates display data for the operation status screen GM1 displayed on the display unit 33 of the server 30 and the display unit 53 of the user PC 50 based on the data registered in the updated database 37z (T19).

  The server 30 displays the wide-area operation status screen GM1 on the display unit 33 based on the created display data (T20). The server 30 determines whether there is a request for display data from the user PC 50 via the network 70 (T21).

  When the server 30 receives a request for display data from the user PC 50, the server 30 sends display data for the wide area operation status screen GM1 to the user PC 50 via the network 70 (T22).

  The user PC 50 displays the wide area operation status screen GM1 on the display unit 53 based on the display data for the wide area operation status screen GM1 transmitted from the server 30 (T23). The user performs a predetermined switching operation on the wide area operation status screen GM1 displayed on the display unit 53 by selecting the wide area circle graph 80 with the cursor kr (T24). When the user PC 50 receives this operation, the user PC 50 requests display data for the narrow area operation status screen GM2 corresponding to the selected wide area circle graph 80 to the server 30 (T25).

  When the server 30 receives a request for display data from the user PC 50, the server 30 creates display data for the narrow area operation status screen GM2 corresponding to the selected wide area circle graph 80 (T26). At this time, the server 30 may switch the screen displayed on the display unit 33 of the server 30 from the wide area operating status screen GM1 to the narrow area operating status screen GM2. The server 30 returns the display data for the created narrow area operation status screen GM2 to the user PC 50 (T27).

  Based on the display data for the narrow area operation status screen GM2 received from the server 30, the user PC 50 changes the display from the wide area operation status screen GM1 displayed on the display unit 53 to the narrow area operation status screen GM2. (T28).

  The above operation procedure is an example. Here, server 30 responds to the request from user PC 50 and returns the display data for wide area operation status screen GM1. However, regardless of the presence or absence of the request, display for wide area operating status screen GM1 Data may be sent repeatedly. Thus, the user PC 50 can update the wide-area operation status screen GM1 displayed on the display unit 53 in real time.

  In addition, the server 30 initially displays the wide area operation status screen GM1 (including the wide area circle graph 80), and when the zoom operation is accepted, the server 30 switches to the narrow area operation status screen GM2. . That is, the server may first display the narrow area operation status screen GM2 (including the vehicle mark 90) and switch to the wide area operation status screen GM1 when the wide operation is received.

  Moreover, when a management system is comprised by three apparatuses, a vehicle-mounted device, a server, and user PC, a server does not need to have a display part by utilizing the display part of user PC. Moreover, the management system may omit the user PC and may be configured by two devices of an on-board unit and a server (including a display unit).

  With the above configuration, even when a large number of vehicles exist in a predetermined area of map information, the management system 5 of the present embodiment collectively displays the position information and the operating state of these vehicles, so on the map It is possible to suppress the problem that a large number of vehicle information is displayed and difficult to view, and the data to be displayed increases and it takes time to display. Moreover, the tendency regarding the operation state of the vehicle located in the predetermined area | region can be grasped | ascertained easily.

  In this way, since the tabulated result is displayed on the display device, the number of vehicles and the operating condition are displayed on the map even if the number of vehicles increases, compared to the case where the operating condition of each vehicle is displayed. The time to display can be shortened. In addition, even when the number of vehicles increases, each vehicle is not displayed like a point, so that the number of vehicles and the operation status can be easily seen. Therefore, when a portable terminal such as a smartphone is used as a display device, the user can visually recognize the number and operation status of many vehicles displayed on the map even if the screen size is small. Moreover, even if the number of vehicles increases and display data to be updated increases, the time until drawing can be shortened.

  Further, when a zoom operation (instruction for enlargement) is input to the map information on which the result of the aggregation is displayed, the CPU 31 replaces the display of the result of the aggregation with GPS position information of each vehicle and ignition on. Since the / off information is displayed on the display unit 33 of the server 30 and the display unit 53 of the user PC 50 in association with the enlarged map information, when it is desired to grasp position information and operation information of each vehicle, map display It can be easily confirmed on the screen by enlarging.

  As described above, when the user wants to know in detail the narrow area on the map that is particularly focused, the zoom operation enlarges the predetermined area to be focused, and the GPS position information of each vehicle and the ignition on / off Information can be displayed. Therefore, the convenience of the user is improved. In addition, when the map is enlarged, the number of vehicles included in a predetermined area on the enlarged map is limited. That is, since the number of vehicles included in the enlarged predetermined area is smaller than the number of vehicles included in the wide area, even if the GPS position information and ignition on / off information of each vehicle are displayed, the display time is Can be avoided.

  In addition, the database 37z registers (records) each vehicle 3 and information representing the attribute of the vehicle 3 in association with each other. Since the CPU 31 reflects the attribute on the wide area pie chart 80 which is the result of the counting, the CPU 31 can perform the counting according to the attribute of the vehicle for each predetermined area. Therefore, for example, the operating condition of the vehicle in a specific area can be tabulated by industry or company and utilized in the sales policy of the company.

  As described above, by reflecting the attribute, it is possible to enhance the utility value of the GPS position information and the ignition on / off information of a plurality of vehicles which are the result of the aggregation. For example, when the attribute is a company, the operating status of vehicles owned by the company and other companies can be grasped and can be used for commerce. Also, if the attribute is a business type, for example, in the case of the transportation business, it is possible to discard vehicles with low operating rates or divert them to another area. In addition, when the attribute is a car type, it can be understood that the area is a region where light vehicles frequently travel or a region where many large vehicles travel, and this can also be used to determine a travel route.

  The technical scope of the present invention is not limited to the above-described embodiment. The embodiments described above can be accompanied by various modifications and improvements within the technical scope of the present invention.

  For example, the display device capable of displaying the operation status screen is an external display device such as an external display device directly connected to the server or a digital signage connected via a network, in addition to the display unit inside the server and the user PC. It may be.

  Further, in the above embodiment, the ignition on / off information is used as the information representing the operating state, but when the situation in which the vehicle is actually traveling is made into the operating state, after the ignition on as the information representing the operating state The data of the vehicle speed sensor of may be used. In this case, it is also possible to obtain information on a non-operating vehicle, such as resting while idling.
