Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a digital operation recorder mounted on a vehicle.
[Prior art]
[0002]
The digital operation recorder is mounted on a vehicle such as a truck and records various operation data such as a travel distance. This operation data is automatically calculated based on the detection value of the vehicle speed sensor, and is recorded on a recording medium such as a memory card. Data is automatically input to a computer connected to the reading device by reading this memory card with a reading device installed in a business office, and is also used to automatically create a daily operation report.
[0003]
By the way, in creating the daily driving report, in order to easily grasp the daily operation history of the vehicle, a plurality of graph displays showing the daily vehicle operation status are configured and displayed in an arbitrary display form. I am letting. This makes it possible to display a graph in an appropriate display format as needed, such as when you want to know the overall daily operating situation or when you want to know the operating situation during a specific time period. Know the situation more precisely.
[0004]
FIG. 5 shows an example of a graph showing an operation situation created by a conventional general digital recorder. (A) is a 24-hour display graph representing the entire daily operating situation, where the horizontal axis represents the operating time zone and the vertical axis represents the speed ([km / hour]) corresponding to the operating time zone. (B) is an 8-hour display graph displaying only 8 hours in the entire daily operation. This selects an arbitrary time zone (for 8 hours) from the 24-hour display graph of (A), and displays the operation status in the selected time zone as a graph on the entire screen.
[0005]
(C) represents the 4-minute display graph which displays the operation status only for 4 minutes in the arbitrary time slot | zones in the same day as (B). This makes it possible to know the details of the operation status in a specific time zone more precisely.
[0006]
In general, a digital operation recorder, which is a field to which the technology related to the present invention belongs, is obliged to have a function for displaying the above three types of graph display forms.
[Problems to be solved by the invention]
[0007]
However, the conventional operation status graph display as described above has the following problems. That is, when looking at the detailed operation status in a specific time zone while looking at the 24-hour display graph of (A), it is necessary to open the 8-hour display (B) or 4-minute display (C) graph. is there. However, it is impossible to open these graphs simultaneously on the same screen, and the user has to check a plurality of graphs while switching the screens. With this method, the management of the operation status of a single vehicle requires the trouble of checking the operation status while switching multiple graphs on the screen, and at the same time, there is a risk that the accurate operation status cannot be grasped. It was.
[0008]
The present invention is for solving the problems related to the graph display of the operation recorder as described above, and can display the entire operation status of the day and the operation status of a specific time zone simultaneously by a simple operation. It aims to provide a method.
[Means for Solving the Problems]
[0009]
In order to solve the above problems, in the present invention, in the operation management system for taking out and managing the daily operation status as data, as a means for displaying the data representing the operation status, the daily operation status on the same graph. In addition to showing the whole, among the time axis of the graph representing the daily operation status, (a) the display width of the graph is automatically enlarged only for the traveling time zone, and for the stopped time zone The display width of the graph is automatically reduced and displayed, or (b) the time zone where the vehicle is traveling at a certain speed or more and is automatically enlarged only for a predetermined time zone, It is possible to perform any display of automatically reducing and displaying the time zone other than (Claim 1).
[0010]
The operation management system is characterized in that the display width of the graph can be arbitrarily changed not only with respect to the time axis but also at an arbitrary speed on the speed axis.

In this graph, when the time T = T1 on the graph is clicked on the horizontal axis, the display width is expanded so that the details of the operation state at the time T = T1 are shown.
[0019]
In general, in the operation recorder, as described above, (i) a 24-hour display for representing the entire operation status of the day, and (ii) a portion that is mainly operated within the day is expanded. It is necessary to have a function of performing at least three kinds of display of eight hours display for displaying and (iii) four minutes display indicating details of the operation state at a specific time, but the display width expansion and contraction performed in the present invention The ratio can be arbitrarily changed, and may be enlarged on an 8-hour display scale or may be enlarged on a 4-minute display scale. FIG. 3 shows an example in which the operation status at time T = T1 is displayed on a 4-minute display scale.
[0020]
Further, the display width may be set in advance on the software program, and may be arbitrarily determined by changing the setting as necessary.
[0021]
Furthermore, when the mouse pointer is moved on the horizontal axis in order to save time and effort for searching for the time T1 on the horizontal axis (time axis), the time corresponding to the position of the pointer is automatically displayed next to the pointer. You may do it.
[0022]
In this embodiment, it can be an effective system for managing the operation status during a day (especially, a normal carrier) when operating in a time zone where the driving is concentrated.
[0023]
FIG. 4 shows a second embodiment of the present invention. In the first embodiment, the display width can be expanded and contracted in order to know the detailed operation status at a specific time. However, in the present embodiment, the display width at the velocity V = V1 on the vertical axis is arbitrarily expanded. I have to. This makes it possible to visually read detailed speed data at an arbitrary speed.
[0024]
Further, when the mouse pointer is moved on the vertical axis in order to save time and effort on the horizontal axis (speed axis) of the speed V11, the speed corresponding to the position of the pointer is automatically displayed next to the pointer. You may do it.
[0025]
This embodiment is effective in managing the operation status when operating in an area (for example, an expressway) where speed restrictions are severe.
[0026]
Further, the embodiment of the present invention is not limited to the above two examples. As another example, among the graphs representing the daily operation status, the display width of the graph is automatically enlarged and stopped only for the operating time zone (the driving time zone). For a certain time zone, a form such as automatically reducing the display width of the graph can be considered. It is assumed that the ratio of the enlargement width and the reduction width in this embodiment can be set as required.
[0027]
Also, in the above example, the display range of the enlarged or reduced graph is not determined by the time zone indicating whether or not the vehicle is operating, but only the time zone where the vehicle is traveling at a certain speed or higher is enlarged and displayed. However, the time zone during which the vehicle is traveling at a lower speed may be displayed in a reduced size. Further, a specific time zone may be determined in advance, and the graph may be enlarged and displayed only in that time zone. Further, the graph may be enlarged and displayed only for a specific time zone in which both of them are combined and traveling at a certain speed or higher.
