2. Description of the Related Art For example, a vehicle operation information collection / analysis system for collecting and analyzing operation information of business vehicles such as trucks, taxis, delivery vehicles and the like is mounted on a vehicle and measures a speed and a traveling distance which change every moment. The on-board device generally referred to as a digital tachograph that monitors and converts a signal obtained by the monitoring into digital data and stores this in a storage medium such as an IC memory card; FIG. 9 is a diagram illustrating an example of an analysis device that reads digital data in a storage medium stored in the storage device, analyzes the read digital data, and collects vehicle operation information necessary for vehicle management.

In FIG. 1, reference numeral 1 denotes a rotation sensor which inputs a rotation corresponding to the rotation speed of an axle from a transmission 2 of a vehicle, converts the rotation into a pulse signal having a frequency proportional to the rotation speed, and outputs a pulse signal. This is an in-vehicle device that samples and inputs a pulse signal from the sensor 1, calculates an instantaneous speed and a traveling distance by calculation, and stores these data. An IC memory card 4 as a portable storage medium can be detachably mounted on the in-vehicle device 3A. By mounting the IC memory card 4 on the in-vehicle device 3A, the speed, distance, and the like are stored in the form of digital data.

In FIG. 1, reference numeral 5 denotes an analyzer installed in an office or the like for controlling the operation of the vehicle. An IC memory card 4 removed from the in-vehicle device 3 is attached to the analyzer 5. In addition to reading digital data from the IC memory card 4 and saving it on a storage medium such as a floppy disk, it also collects vehicle operation information obtained by analyzing the saved digital data. In order to store the data, the IC memory card 4 to be mounted on the in-vehicle device 3A and used is initialized and setting data and the like are stored.

In the system having the above configuration, the IC
Even if the storage capacity of the memory card 4 is not so large,
In order to collect all the information in one operation of the vehicle without interruption, the in-vehicle device 3A performs a predetermined data compression process on the speed data, which is enormous data amount as it changes with time, in particular. The data amount is stored in the IC memory card 4 after being reduced.

[0006] By the way, in particular, trucks and taxis,
In industries where the length of one operation is long and the working hours from start to end are longer than those in normal industries, it is stipulated that if the continuous working hours reach the specified number of hours, a break for a certain period of time will be taken. ing. Therefore, conventionally, when the information stored in the IC memory card 4 is analyzed by the analysis device 5, the longest continuous time of the speed $ 0 is confirmed, and based on this, it is determined whether or not the break has been taken as specified. Had been confirmed.

However, the information that the analysis device 5 needs to analyze to confirm the longest continuous time of the speed ≠ 0, that is, I
The speed information in the C memory card 4 is, as described above,
Since the data has been compressed in the in-vehicle device 3A,
In the above-described conventional system, the analysis of the longest continuous time of the speed ≠ 0 cannot be performed unless the compressed speed data is expanded to time-series data at predetermined time intervals. For this reason, conventionally, when analyzing the longest continuous time of the speed ≠ 0, expansion of the speed data, time-series data conversion at predetermined time intervals,
In addition, it takes a considerable amount of time to determine whether or not the speed of the speed data converted into the time-series data at the above-mentioned predetermined time ≠ 0, and defines a break after working for a predetermined continuous time. There was a problem that it was not possible for the analyzer 5 to quickly confirm whether or not it passed.

In view of the above-mentioned conventional problems, the present invention collects vehicle operation information indicating a running state of a vehicle, which changes every moment, in the form of digital data, performs predetermined compression processing on the collected data, and then performs storage processing. In the in-vehicle device for collecting vehicle operation information to be stored in the storage device, the analysis device reads out the storage information in the storage medium and performs an analysis process later. When outputting information on items whose state is continuously invariable as in the case of, for example, the information stored in the storage medium has an added value so that the analyzer can quickly generate the information on the continuous invariant items. It is an object of the present invention to provide an in-vehicle device for collecting vehicle operation information that can be operated.

In the in-vehicle device for collecting vehicle operation information for storing operation information, based on the vehicle operation information before the predetermined compression processing collected in the form of the digital data, continuous invariable item information for generating the continuous invariant item information Generating means, and continuous invariable item information for storing the continuous invariant item information of the running state of the vehicle generated by the continuous invariant item information generating unit in the storage medium for each operation of the vehicle. It was configured to provide a recording means.

For this reason, when the analyzing device that has read the information from the storage medium outputs the continuous invariant information, it is not necessary to perform the process of generating the continuous invariant information from the vehicle operation information after the compression processing. As a result, the information stored in the storage medium can be given an added value so as to produce an advantage that the output processing of the continuous invariant item information can be speeded up.
