BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital vehicle operation recording device which collects vehicle operation information including the traveling speed of a vehicle which changes from moment to moment in the form of digital data, and more particularly to vehicle operation data together with the time of occurrence thereof. The present invention relates to a digital vehicle operation recording device including an in-vehicle device that records and collects data in a storage unit and a portable device that is connected to the in-vehicle device and that stores data stored in the storage unit in a memory.

[0002]

2. Description of the Related Art Conventionally, an apparatus of this type has been used by being mounted on a vehicle to collect operation information of each vehicle for managing a transportation vehicle such as a large number of trucks owned by a courier and the like. The configuration is shown in FIG. In the figure, 1 is an in-vehicle device that is attached to a vehicle and collects vehicle operation information, and 2 is a device called a handy numeric keypad that is portable by a driver. The mobile device 2 includes a display device 2a and a keyboard 2b and has a built-in memory for storing data. The mobile device 2 has a connector hole 1b provided on the front surface of the vehicle-mounted device 1 in which the display device 1a is arranged. Correspondingly connected to each other in a paired manner, the display 2a and the keyboard 2b are used for transportation work, key input for slips, and data input from the vehicle-mounted device 1.
It has a function to send the in / out command.

The operation information collected by the illustrated digital vehicle operation recording device includes information related to the operation of the vehicle itself and information related to the transportation work. The former includes data on traveling speed and traveling distance of the vehicle from the leaving of the vehicle departing from the truck base to the entering of the vehicle returning to the truck base, and these are mainly collected by the vehicle-mounted device 1. The latter includes time-series data indicating the status of delivery work, and these are collected by the mobile device 2. All of the above-mentioned former data are finally transferred to the mobile device 2 and stored in the internal memory thereof, and then handed over to the vehicle manager for various kinds of analysis.

A device 3 called a notebook computer, which is used for setting various data in the in-vehicle apparatus 1 and is suitable for carrying, is connected in place of the portable device 2 and the collected data in the memory is connected. It may be applied for reading.

[0005]

By the way, the vehicle-mounted device 1
The data collected by is roughly divided into large volumes of data such as velocity compression data to see details of velocity changes, and relatively small volumes of data such as maximum velocity and distance collected at regular intervals. However, detailed data is not required for the data corresponding to the daily report normally recorded by the driver.

However, in the above-mentioned conventional apparatus, all of the information collected by the vehicle-mounted apparatus 1, that is, a large amount of data that is almost unnecessary, is always sucked up by the portable device 2 or the device 3. Therefore, there is a problem that a huge amount of time is required for downloading data and processing the downloaded data.

Although a proposal has been made to reduce the processing time for the downloaded data, this proposal allows all the data to be downloaded regardless of the necessity of the data, and the driver must wait during that time. Besides, there is a limit to the reduction of processing time because it involves the processing of unnecessary data.

Therefore, in view of the above-mentioned conventional problems, the present invention provides a digital vehicle operation recording apparatus capable of shortening the waiting time for a driver by shortening the time taken for data to be collected under normal conditions. It is an object.

[0009]

In order to achieve the above-mentioned object, a digital vehicle operation recording device made according to the present invention comprises:
As shown in the basic configuration diagram of FIG. 1, the vehicle operation data including the traveling speed of the vehicle, which changes moment by moment, is written into the writing means 11b.
According to a request signal from the outside, the output means 11c outputs the collected data to the output means 11c in order to output the collected data to the storage means 12b. However, a simple data area 12 for recording simple data
b ₁ and detailed data area 12b ₂ for recording detailed data
The simple data output means 1 for outputting the simple data recorded in the simple data area 12b ₁ according to a simple data request signal from the outside.
1c ₁ and a detailed data output means 11c ₂ for outputting detailed data recorded in the detailed data area 12b ₂ in response to a detailed data request signal from the outside.

[0010]

In the above structure, the simple data area 12b of the storage means 12b is responsive to a simple data request signal from the outside.
_The simple data recorded in ₁ is output by the simple data output means 11c _{1 of the} output means 11c, and the detailed data area 1 of the storage means 12b is output in response to a detailed data request signal from the outside.
Since the detailed data recorded in 2b ₂ is output by the detailed data output means 11c _{2 of the} output means 11c, the data required for normal vehicle management can be obtained by outputting simple data. It is possible to selectively output detailed data only when it is necessary.
