DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital operation recorder mounted on a vehicle.

[Prior art]

[0002] A digital operation recorder is mounted on a vehicle such as a truck and records various operation data such as a running distance. The operation data is automatically calculated based on the value detected by the speed sensor of the vehicle, and is recorded on a recording medium such as a memory card. When this memory card is read by a reader installed in a business office, data is automatically input to a computer connected to the reader and used to automatically create a daily operation report.

[0003] In the above-mentioned digital operation recording device, when a vehicle-mounted device mounted on a vehicle acquires speed data, time data, and mileage data, the vehicle-mounted device uses a GPS (Global Positioning Sys- tem).
tem) function, obtains information such as the current location and the traffic condition of the vehicle equipped with the on-vehicle device, and designates the vehicle to travel according to the current location and the traffic condition from the office managing the vehicle. It is common practice to determine how much time the vehicle needs to reach its destination, and so on.

[0004] The daily driving report, which indicates the daily operation status in the above-mentioned digital operation recording system, is a time-series display of the speed of the vehicle corresponding to time or time. In order to easily grasp the history, a graph showing the vehicle operation status for one day is configured to be displayed based on a plurality of time axes, and the display form of the graph corresponding to the time axis as necessary Is displayed. This makes it possible to know the operation status of each vehicle more precisely, such as when the user wants to know the entire operation status of the day or when he wants to know the operation status in a specific time zone.

FIG. 6 shows an example of a graph showing an operation status created by a conventional general digital operation recording system. (A) is a 24-hour display graph showing the entire operation status of a day, in which the horizontal axis represents the operation time zone and the vertical axis represents the speed ([km / hour]) corresponding to the operation time zone. (B) is an eight-hour display graph that displays only eight hours of the entire operation of the day. This is (A) 2
An arbitrary time zone (for eight hours) is selected from the four-hour display graph, and the operation status in the selected time zone is displayed as a graph on the entire screen.

[0008] (C) shows a four-minute display graph that graphically displays the operation status of only four minutes in an arbitrary time zone of the day, similarly to (B). As a result, the details of the operation status in a specific time zone can be known more precisely.

In general, a digital operation recorder, which is a field to which the technology relating to the present invention belongs, is required to have a function of displaying the above three types of graph display forms.

[Problems to be solved by the invention]

However, the conventional operation status graph display as described above has the following problems. That is, in general, although a road on which a vehicle passes is provided with a speed limit corresponding to each region as shown in FIG. It cannot be read from the graph whether the vehicle has traveled in such an area, for example, has traveled on a highway. Specifically, even when the vehicle is traveling in the area A where the speed limit is 40 km / h, and when the vehicle is traveling in the area B where the speed limit is 60 km / h at the same speed, a distinction is made on the displayed graph. Not done.

[0009] Further, it is not possible to read the situation of the traveling area, that is, how the traffic congestion or the traffic accident in the traveling area affects the operation of the vehicle from the displayed graph.

SUMMARY OF THE INVENTION The present invention is to solve the above-described problem relating to the graph display of the operation recorder, and it is possible to refer to the operation status in the area where the speed limit is different, and to check the status of the area where the travel is performed.
