[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle operation information collection / analysis system for collecting and analyzing vehicle operation information including information indicating the speed of a vehicle which changes from moment to moment in the form of digital data. The present invention relates to a vehicle operation information collection / analysis system which, when analyzing information, draws the information on a graph showing changes over time in a predetermined time zone and outputs the graph.

[0002]

2. Description of the Related Art This type of vehicle operation information collection / analysis system is mounted on a vehicle and monitors the time-varying speed and mileage, and converts the signals obtained by this monitoring into digital data. An in-vehicle device that is generally called a digital tachograph that is stored in a storage medium such as a memory card and an office that manages the vehicle are installed, and the digital data in the storage medium that is stored by the in-vehicle device is read, and the read digital data is read. An analyzing device for analyzing and collecting vehicle operation information necessary for vehicle management is configured as shown in FIG.

In the figure, reference numeral 1 is a rotation sensor for inputting rotation according to the number of rotations of an axle from a transmission 2 of a vehicle, converting this rotation into a pulse signal having a frequency proportional to the number of rotations, and outputting the pulse signal 3A. This is an in-vehicle device that samples and inputs a pulse signal from the sensor 1, calculates an instantaneous speed and a traveled distance, performs a predetermined data compression process, and stores the data. An IC memory card 4, which is a portable storage medium, can be removably attached to the in-vehicle device 3A. The IC memory card 4 has
By mounting this on the vehicle-mounted device 3A, the speed and distance are stored in the form of digital data.

Further, in the figure, 5B is an analysis device installed in an office or the like that manages the operation of the vehicle. To this analysis device 5B, the IC memory card 4 removed from the in-vehicle device 3A should be attached. Read the digital data from the IC memory card 4 and save it in a storage medium such as a floppy disk, and analyze the saved digital data to collect vehicle operation information, perform printing and display, and perform digital printing. In order to store data, initialization of the IC memory card 4 mounted on the in-vehicle apparatus 3A and used and storage of setting data and the like are performed.

In the system having the above-mentioned configuration, FIG.
As shown in FIG. 4, the time series data D5 of the traveling speed that changes with time is drawn on one screen in the form of a graph in which the vertical axis and the horizontal axis represent time and speed on the analysis device 5B side. Based on the graphs, the operation status including the change of running speed with the passage of time is evaluated. In order to perform this evaluation, it is necessary to accurately check the traveling speed of the attention point P in the time-series data D5, but relying only on the time axis of the graph whose size is limited, It is very difficult to confirm the accurate traveling speed.

Therefore, it is conceivable to display the cursor simultaneously with the time series data D5 on the graph and use the cursor to assist in confirming the traveling speed of the point of interest in the time series data D5. As a conventional method of displaying a cursor over such a graph, there is, for example, a data display method disclosed in JP-A-1-138414. In this data display method, a cursor is used to specify the data part of the analysis target that is extracted from the graph in which the compressed running speed data is plotted as it is, expanded, and displayed separately. It extends in a direction orthogonal to the axis.

Therefore, if the cursor orthogonal to the time axis of the graph is displayed on the graph of FIG. 24 at the same time, as shown in FIG. 25, the cursor passes through the attention point P of the time series data D5. C5 is positioned and the same scale (not shown) as the time axis is attached to this cursor C5, or
Alternatively, instead of this scale, as shown in the figure, the time T1 of the point of interest P of the time-series data D5 overlapping the cursor C5
And the traveling speed V1 are also displayed simultaneously in an auxiliary manner.

[0008]

However, in such a display form, the time-series data D of the drawn graph is displayed.
When evaluating how the traveling speed of the vehicle fluctuates with respect to the speed limit on the basis of 5, while moving the cursor C5 little by little in the time axis direction, the time series intersects with the cursor C5 each time. It is necessary to read the speed of the data D5 portion with the eyes, or to confirm and memorize it by checking the display of the traveling speed V1. For example, at a glance on the graph, it is possible to see how many parts exceed the speed limit. There was a problem that could not be identified with. Then, when the speed limit changes during one operation, such as when traveling on both general roads and highways, it is possible to determine how much speed has been exceeded in what time zone with just a graph of traveling speed. There is a problem in that it becomes extremely difficult to analyze and evaluate detailed contents in a graph, and the burden on the analysis staff increases accordingly. In addition, such a problem can be similarly applied to, for example, when the engine is excessively inflated, or when the fluctuation of the engine speed is analyzed in order to evaluate the engine life.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to collect and analyze vehicle operation information indicating a running state of the vehicle, which changes from moment to moment, in the form of digital data. In the operation information collection and analysis system, changes in the running speed with respect to the speed limit, changes in the actual engine speed with respect to a predetermined reference speed, etc., easily analyzed with respect to changes in the running state with the running of the vehicle, An object of the present invention is to provide a vehicle operation information collection / analysis system that can easily obtain an evaluable output.

[0010]

In order to achieve the above-mentioned object, the present invention, as shown in the basic configuration diagram of FIG. 1, stores traveling state data that fluctuates with the operation of a vehicle as a portable storage medium 4.
The vehicle-mounted device 3 for writing vehicle operation information by writing to the vehicle, and the running state data written in the storage medium 4 are read, and the running state indicating a time-series change of the running state of the vehicle is read from the read running state data. The series data D is obtained, the obtained traveling state time series data D, a cursor C indicating a reference value for the traveling state time series data D, and the traveling state time series data D portion exceeding the reference value is set to the reference value. It is characterized in that it is provided with analysis devices 5 and 5A for drawing a graph in which the section information S for distinguishing from the running state time-series data D within and the same time scale are drawn.

Further, according to the present invention, the in-vehicle device 3 has a reference value-time zone setting means 36 for setting the reference value and a time zone to which the reference value is applied. Cursor data consisting of the reference value set by the setting means 36 and an application time zone of the reference value is written in the storage medium 4, and the analyzers 5 and 5A are based on the cursor data read from the storage medium 4. The above graph is drawn. Furthermore, the present invention provides the analysis device 5, 5A.
Has a reference value changing means 51ba for increasing / decreasing the reference value, and changes the position of the cursor C in the graph to the traveling state according to the reference value increased / decreased by the reference value changing means 51ba. It is assumed that the series data D is changed.

The present invention also provides the analysis device 5, 5A.
Has a graph time zone designating means 51bb for designating a time zone of the time scale, and draws the graph in the time zone designated by the graph time zone designating means 51bb. Further, in the present invention, the analysis devices 5 and 5A are
Time information indexing means 51A for indexing time information indicating the time of the running state time series data D portion exceeding the reference value.
And the graph in which the time information indexed by the time information indexing means 51A is described as the classification information S is drawn.

The present invention also provides the analysis device 5, 5A.
Has a drawing form changing means 51B for setting the running state time series data D portion exceeding the reference value to a drawing form different from the running state time series data D portion within the reference value. The graph in which the running state time series data D portion exceeding the reference value different from the running state time series data D portion within the reference value is described as the classification information S is drawn. Further, the present invention provides
The analyzers 5 and 5A have excess number indexing means 51C for indexing the number of times the running state time series data D exceeds the reference value on the graph, and the excess frequency indexing means 51C index. The graph in which the number of times is described as the classification information S is drawn.

[0014]

In the above structure, the analyzing devices 5 and 5A generate the running state time series data D indicating the time series changes of the running state data on the basis of the running state data written in the portable storage medium 4 by the in-vehicle device 3. Further, the traveling state time-series data D obtained, a cursor C indicating a reference value for the traveling state time-series data D, and the traveling state time-series data D portion exceeding the reference value are within the reference value. Since a graph in which the division information S for distinguishing from the running state time series data D is plotted on the same time scale, it is difficult to analyze and evaluate only the running state time series data D, and the fluctuation of the running speed with respect to the speed limit. Or the transition of the actual engine speed with respect to the predetermined limit engine speed,
It is possible to easily analyze and evaluate the change of the traveling state with respect to the reference value, which changes with the traveling of the vehicle, by viewing together the traveling state time-series data D with the cursor C and the segment information S drawn in the graph. In other words, it is possible to obtain an output that facilitates such fine analysis and evaluation.

The in-vehicle apparatus 3 writes in the storage medium 4 cursor data consisting of a standard value set by the standard value-time zone setting means 36 and a time zone to which the standard value is applied. By making the analysis devices 5 and 5A draw a graph based on the cursor data read from the storage medium 4, for example, when the reference value changes several times during one operation, the data is used as travel information. At the same time, the data can be transferred from the vehicle-mounted device 3 to the analysis devices 5 and 5A, and the analysis devices 5 and 5A can draw a cursor C according to the reference value on a graph according to the transferred data. Further, the analyzers 5 and 5A have their own reference value changing means 51b.
By increasing / decreasing the reference value by a and changing the position of the cursor C in the graph with respect to the running state time-series data D, the reference value is set to an arbitrary value according to the evaluation content at the analysis stage. It is possible to make the graph draw the classification information according to the reference value.

Further, the analysis devices 5 and 5A draw the graph on the time scale of the time zone designated by the graph time zone designating means 51bb owned by the analyzers 5 and 5A, so that the content limited to the time zone to be analyzed can be obtained. It is possible to output a graph and perform detailed analysis and evaluation. Further, the time information indicating the time of the running state time series data D portion that exceeds the reference value is calculated by the time information indexing means 51A of the analyzers 5 and 5A, and this time information is plotted in the graph as the classification information S, The section on the graph defined by the running state time series data D and the cursor C allows not only visual confirmation of the running state time series data D portion exceeding the reference value, but also the running state time series data D portion of the time. The information makes it possible to confirm it as data such as numerical values.

Further, the analyzing devices 5 and 5A have their own drawing form changing means 51B, and the traveling state time series data D portion exceeding the reference value is used as the classification information S as the division information S and the traveling state time series within the reference value. By drawing in a different form from the data D portion, it is possible to more easily perform the traveling state time series data D portion that exceeds the reference value and the traveling state time series data D portion that is within the reference value, which are divided by the cursor C. Can be distinguished. In addition, the number of times the running state time series data D exceeds the reference value on the graph, which the analyzers 5 and 5A have calculated by the excess number indexing means 51C, is recorded in the graph as the classification information S. By doing so, similarly to the case where the time information indexed by the time information indexing means 51A is shown in the graph as the classification information S, the running state time series data D portion exceeding the reference value can be confirmed as data such as numerical values. It will be possible.

[0083]

As described above, according to the present invention, an on-vehicle device that collects vehicle operation information by writing traveling state data that fluctuates with the operation of a vehicle in a portable storage medium, and the storage medium. The written running state data is read, running state time series data indicating a time series change of the running state of the vehicle is obtained from the read running state data, and the obtained running state time series data and the running state time Graph showing the cursor indicating the reference value for the series data and the segment information for distinguishing the running state time series data portion exceeding the reference value from the running state time series data portion within the reference value on the same time scale And an analyzing device for drawing.

Therefore, it is difficult to analyze and evaluate the traveling state time-series data only, and it is difficult to analyze and evaluate the traveling speed with respect to the speed limit, the change in the actual engine speed with respect to a predetermined engine speed limit, etc. It is possible to easily analyze and evaluate the change of the fluctuating running state with respect to the reference value together with the running state time-series data by looking at the cursor and the segment information drawn in the graph together, in other words,
There is an effect such as being able to obtain an output that facilitates such fine analysis and evaluation.

According to the present invention, the on-vehicle device is
It has a reference value-time zone setting means for setting the reference value and a time zone to which the reference value is applied, and the reference value set by the reference value-time zone setting means and the application time of the reference value The cursor data composed of a band is written in the storage medium, and the analysis device draws the graph based on the cursor data read from the storage medium. Therefore, for example, when the reference value changes several times during one operation, the data is passed from the vehicle-mounted device to the analysis device together with the traveling information, and the analysis device determines the reference value according to the passed data. You can draw a cursor on the graph according to.

Further, according to the present invention, the analysis device has a reference value changing means for increasing / decreasing the reference value, and in the graph according to the reference value increased / decreased by the reference value changing means. Since it is configured to shift the position of the cursor with respect to the running state series data in, the reference value is set to an arbitrary value according to the evaluation content at the analysis stage, and the classification information according to the reference value. Can be drawn in a graph.

The driving state time-series data portion that exceeds the reference value has a drawing form changing unit that sets a drawing form different from that of the traveling state time-series data part that is within the reference value, and the drawing form is within the reference value. It is configured to draw the graph in which the running state time-series data portion that exceeds the reference value different from the running state time-series data portion is described as the classification information. Therefore, it is possible to more easily distinguish the running state time-series data portion exceeding the reference value and the traveling state time-series data portion within the reference value, which are divided by the cursor.

Further, according to the present invention, the analysis device has an excess number indexing means for indexing the number of times the running state time series data exceeds the reference value on the graph. The graph in which the number of times determined by the means is described as the classification information is drawn. Therefore, similarly to the case where the time information indexed by the time information indexing means is shown in the graph as the classification information, the running state time series data portion exceeding the reference value can be confirmed as data such as numerical values.
