Abstract

(57) [Summary] This bulletin contains application data before electronic filing, so abstract data is not recorded.

Description

[Detailed description of the invention] [Industrial application field] This invention collects data using a digital driving recorder.

The present invention relates to a processing device that processes various types of data to be recorded.

[Conventional technology]

A digital driving recorder, also known as a digital tachometer, records in its memory various work management data such as momentary driving speed, engine speed, and distance traveled, as well as work details, operation locations, and transported items.

Such driving recorders are required to store driving data in a nearly continuous format, so they must handle extremely large amounts of data. for example,
If 2 bytes of data are required every 0.5 seconds for 24 hours, then 24' x 60' x 60' x 12 x 2 = 345.
The amount of data is 6 Kbytes. For this reason, it is desirable to perform data compression using various methods, but even with these methods, the current situation is that the amount of data in units of bytes still has to be handled on the order of several tens of bytes.

[Problem that the invention seeks to solve]

In other words, there is a problem that the amount of data to be handled is too large.

Furthermore, the data from the driving recorder is generally recorded in a cassette type memory, which is taken out from the vehicle every time the driver finishes his or her shift and processed by a computer in the business office. However, since the end times of drivers' shifts are often concentrated, it takes a lot of time to process the data. As a result, a situation arises where the computer is waiting for processing, and even though data is stored digitally in memory, there is a delay in daily report creation, or it takes time to correct the daily report data and processing cannot be completed on the same day. There is a problem in that there are cases where the process does not end.

On the other hand, the data handled by a digital driving recorder is: a) Time that is required to be recorded by law.

Data such as driving speed and mileage b) Various driving data that is not legally required to be recorded, such as engine speed, idling status, mileage by road, etc. C) Mileage by driver It can be divided into management data for each driver or vehicle, such as maximum speed, overspeed time, mileage for each vehicle, number of trips, name and quantity of transported items, various fees, time for one meal or nap, etc. These data are originally generated in chronological order, but processing all of this data in chronological order requires a large amount of time, and to shorten this time a large-scale computer system is required. However, there is also the problem that the system becomes large and expensive, resulting in a heavy economic burden.

Therefore, it is an object of the present invention to significantly reduce the data processing time, particularly by a computer system, by devising a data processing method.

[Means for solving problems]

a reading device that reads out the recorded contents of a removable memory (cassette type memory) that records various data including the running speed of the vehicle collected by a digital driving recorder mounted on the vehicle when it is set; A host computer is provided which is connected to this via a predetermined communication means and which receives the data and performs predetermined processing including the creation of a daily report.

[Effect]

In the cassette type memory, first data necessary for daily report creation and second data other than that are recorded in separate areas, while the reading device records this first data. When the second data is read and stored in the external auxiliary storage device, only the first data is sent to the host computer, and when there is a request from the host computer, the data saved in the external auxiliary storage device is sent. By doing so, at least daily reports can be created in a short time, and other data can be sent to the host computer for processing as needed, thereby improving processing efficiency.

〔Example〕

FIG. 1 is a block diagram schematically showing an embodiment of the present invention. That is, a digital operation recorder (electronic tachograph body) 1 mounted on a vehicle 2 such as a truck or bus.
and a removable memory cassette (
cassette type memory) 19, and a computer system (cassette reader 31, computer 32, printer 33A
, 33B, etc.). Note that 12 is a speed sensor, and 18 is an operation section.

FIG. 2 is a configuration diagram showing a digital driving recorder mounted on a vehicle. In the figure, reference numeral 10 denotes a data processing device such as a one-chip microcomputer, and rotation sensor 11. When the number of pulses of the running sensor 12 is counted and data is set in the internal memories 17A and 17B at fixed time intervals (for example, 0.5 seconds), the data is also stored in the memory cassette 19. Reference numeral 15 denotes a display lamp, which is used to guide the user to the remaining amount of data memory in the memory cassette 19, etc. In addition, an operation section 18 with manual key operation and an LCD display is provided, which allows various data (
work data, numerical value 2 names, etc.) in memory 17A, 17B.
Or 19 can be stored. 16 is a memory for the microcomputer, 13 is a power supply circuit such as a battery (battery bath control circuit), and 14 is a clock LSI for setting time data.

Although driving data is appropriately compressed and recorded, such compression also generates a large amount of driving data. by the way,
This kind of data is a kind of primitive data and is not always needed, so it is usually organized to create various types of data as shown below.

b) Data for each vehicle; c) Data for each driving sound; c) Common data for drivers. There is a lot of data that needs to be done, and the operation section 18 is provided for this purpose. Since there are various possible input methods, the details will be omitted, but an example of the operation section is shown in FIG. 3. This is the display section 18
A and a keyboard section 18B, and desired data can be input by the cooperative operation of these sections.

This input data is set as one data block in, for example, 40 bytes of memory. To explain with reference to FIG. 2, these input data are first created by the microcomputer 10 and stored in the data memory 17A.
, 17B. At this time,
Since the data memories 17A and 17B are used alternately, the corresponding memories are used in that order. The memory 16 also includes a ROM for programs.
and a control RAM are prepared, for example, data sampled every 0.25 seconds or a data memory 17.
The data before setting to A, 17B is used for this control R.
It is temporarily stored in AM.

In other words, the data includes fixed data such as travel distance and speed over time created based on work data and driving data, as well as data from sensors and time data that are generated chronologically depending on driving conditions. It can be considered separately from variable data consisting of such data. Therefore, fixed data is assigned a predetermined address area,
In order to use memory effectively, variable data is allocated to other address areas, and the storage direction of fixed data and variable data are reversed as shown in Figure 4. Make it.

The data stored in this way is set in a fixed data area, taking into consideration the nature of the data and the data necessary for creating daily business reports and the like. Although this fixed data varies depending on the operation method, it is considered to be around 5' bytes out of a total of 40 bytes. In other words, it can be seen that it is sufficient to use approximately 1/10 of the total data as data for daily or monthly reports.

FIG. 5 is a flowchart for explaining the operation of FIG. 2.

First, in step S1, it is determined whether data to be stored has occurred. The data to be stored includes data that is generated independently of the operation unit, such as speed data, and data that is generated due to manual keystrokes from the operation unit. Therefore,
If data to be stored is generated, the process advances to S2, and if there is no data to be stored, the process is terminated. Step S
In step 2, it is determined whether or not the data is travel record data, and if it is travel record data, the process advances to S5. In step S3, it is determined whether the generated data is vehicle-side fixed data,
If applicable, proceed to S6. In step S4, it is determined whether the data is fixed data classified by driving sound or not, and if it is fixed data classified by driving sound, the process advances to S7. If not, it is determined that the fixed data is common to all drivers, and the process proceeds to step S8. In addition, in steps 85 to S8, after creating data according to the data format for each store data, the address to store is specified. In step S9, it is determined which data block (see memories 17A and 17B in FIG. 2) is being used, and in step S10 and Sll, the data created in steps 35 to S8 is stored in each block. . Here, step S10. The address spaces of S11 are allocated to the same space. In step S12, the data stored in steps SIO and Sll is stored in the memory cassette 19.

Repeat the above steps.

FIG. 6 is a configuration diagram showing the configuration of the set leader. In the same figure, 31A is a multiplexer, 31B is a floppy disk, 31C is a control CPU, and 31D is an RO.
M and 31E are RAMs, and 31F is a transmission section. In addition, 1
9 is a memory cassette; 32 is a host computer. Further, 32a is an input/output unit of the upper calculation m32.

The cassette reader (reading device) 31 reads the contents of the memory cassette 19 that the driver takes back to the office at the end of his/her shift, and can read all data via the multiplexer 31A.

As explained above, this data includes a fixed data area and a variable data area. For this reason, the cassette reader 3
1 writes all the read data, including the cassette number, etc., to a built-in floppy disk 31B, while sending the data in the fixed data area to the host computer (office computer) 32 via the transmission unit 31F and serial ink face. to be transmitted.

Now, if this fixed data part is, for example, 5' bytes and the transmission speed is 9.6 Kbps (bits/second), then
Assuming the transmission efficiency is 40%, it is possible to transmit data to the host computer in the following manner. Here, if you want to transmit all the data of 40 bytes, the amount of memory is 8 times the above, so 10.4X 8
= 83.2 seconds of communication time is required.

The host computer 32 prints out daily work reports tailored to various uses, but if the data is in this fixed data area, the data can be transmitted within a short time, so it is possible to print out daily reports sufficiently. Become.

In the explanation so far, we have explained the case of just one memory cassette, so the difference in communication time does not seem to be that big. Considering this, it is important to consider how quickly the data transfer can be completed, print out the daily report without waiting for the driver, and have the driver check the daily report data. This is the point. In particular, the driver's work data is key input data, and incorrect data may be input, so it is important to check the daily report as soon as it is fresh in your memory. If 8 happiness k
If the next day arrives, there are many work schedules where the next day is a day off for some drivers, and it is almost impossible to check the daily report after a long vacation. I understand how important it is to publish a daily report.

On the other hand, time-series driving data that was not automatically sent to the host computer is not needed for the time being to create daily reports.
It is only necessary to send a predetermined command from the host computer to the cassette league only when necessary, read out running data including fixed data, and analyze this content to read changes in running speed over time. Another method is to set a floppy disk stored in a cassette reader into another analysis computer or host computer and read the running data.

FIG. 7 is a flowchart for explaining the operation of the cassette league as described above.

First, in step S1, it is detected whether a memory cassette has been set. If it is set, the process advances to step S2, and if it is not set, the process ends. In step S2, data is sequentially read from the memory cassette, and in step S3, all the read data is saved on a floppy disk. In step S4, the read data is data to be transmitted to the host computer,
In other words, it is determined whether the data is fixed data. As a result, if it is fixed data, the process advances to step S5 and the data is transmitted to the host computer. The host computer processes the received data and prints it out to the printer. Step, Pu S6
Then, it is determined whether all data reading from the memory cassette has been completed, and if it has not been completed, the process returns to S2.
The above-described process is repeated until all data reading is completed.

〔Effect of the invention〕

According to this invention, all the data necessary for creating the daily monthly report is created as fixed data, and other driving data (original data regarding time, speed, and distance) is stored as variable data in a chronological manner. In addition to storing all data in a large capacity memory such as a floppy in a cassette league that reads out the contents of the memorized memory card by storing it separately in the driving recorder, it also stores the fixed data necessary to prepare the daily and monthly reports. The data is transmitted to the host computer and the daily report is automatically printed out by the host computer, so the host computer can concentrate on creating only the 8 items, and the data necessary to create the daily report is stored in the address area. Since the data is created in a table format with a fixed table format, it not only becomes easier to create various daily reports and monthly reports for the host computer, but also has the great effect of making it easier to create the programs. Furthermore, since the cassette league side has a built-in large capacity memory, the host computer can be used for purposes other than the operation management system.
