Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a system for recording and analyzing vehicle operating status data.

Drivers of trucks, buses, taxis, etc. are required to prepare daily driving reports (operation hours, total mileage, working hours, contents of transportation, route of operation, etc.), but recording in a book takes time and effort. In addition to putting a strain on the paper, it also stains the recording paper.

In some cases, it was difficult to read later due to wrinkles, etc.

On the other hand, conventional mechanical tachographs record data over a long period of time on a narrow recording surface, so they have the disadvantage of requiring a tremendous amount of effort to decipher the data.

The present invention does not conventionally require much effort from the driver.

In addition, data was collected electronically by the driver's key operations in the car, eliminating the need to create daily driving reports that had poor accuracy.

Performed easily and accurately by analyzing on the ground.

At the same time, operation data that was difficult to read with conventional tachographs is electronically recorded and analyzed, making it possible to record operation records that are easy to read.

The present invention will be explained below with reference to the drawings.

In FIG. 1, reference number 1 indicates a recording device mounted on an automobile 100, and 3 indicates a removable storage device within the recording device. All daily driving report data and operation data collected while the car is running are stored in the storage device 3 and collected at the business office.

The processing device 5 reads the collected data by connecting the storage device fa to the connection device 4 of the analysis device 2 installed in the business office. The analysis device 2 includes an external storage device 6, a display input/output device 7. A modulation/demodulation device 8 and a printing device 9 are connected, and the collected data is outputted to these devices as is or after analysis. The analysis process performed by the processing device is as follows.

(1) Daily driving report creation process (time-mileage analysis process (3) time-speed analysis process (4) time-engine speed analysis process (5) fuel consumption analysis process (6) driver work analysis process (7) There are other complex processes in addition to the seven processes above the vehicle condition analysis process, but they are omitted for the sake of brevity.The contents of the above processes will be further explained.

(1) Daily driving report creation process This process is based on the business data entered by the driver by pressing the keyboard of the recording device 1, and the detection data from the axle load detection device, distance/speed detection device, and engine rotation speed detection device. Create a daily report.

(I) Time-travelling distance analysis Processing The cumulative mileage over time is totaled from the detection data of the distance/speed detection device.

(3) Time-Speed Analysis Processing Based on the detection data of the distance/speed detection device, speed changes with time changes are totaled.

(4) Time-engine rotation speed analysis Based on the detection data of the engine rotation speed detection device, changes in engine rotation speed with time are summarized.

(5) Fuel consumption analysis processing The relationship between fuel consumption and travel distance over hourly changes is compiled based on the detection data of the consumed fuel detection device and the distance/speed detection device.

(6) Driver work analysis processing By operating the display input/output device 7, the time for each job, driving characteristics, etc. of each driver is analyzed and totaled based on the accumulated data stored in the external storage bag f6.

(7) Vehicle condition analysis processing By operation from the display input/output device 7.

Based on the cumulative data stored in the external storage device 6, the mileage, cumulative engine speed, etc. of each vehicle are totaled.

The data compiled by the analysis device is sent to other systems via the modulation/demodulation device 8.

FIG. 2 is a diagram showing the recording device 1 mounted on a truck 100.
10 is a distance/speed detection device, 11 is an engine rotation speed detection device, and 12 is a consumed fuel detection device that detects the flow rate from the fuel tank 13. 14 is an axle load detection device that detects whether or not cargo is loaded.

FIG. 3 is a block diagram of the configuration of the recording apparatus.

A control device 16 controls the operation of the recording device.

The recording device displays business data input from the keyboard 18 on the display 20, as well as time data from the clock device 17, distance/speed detection device 10° engine @ revolution speed detection device 11. II' which is combined with the detected data of the axis and stored in the memory device 19.
) is stored in the memory device. Reference numeral 3 denotes a removable storage device comprising a memory device, a battery 21, and an adapter 22 for reading. 15 is an interface device for the detection device, and f23 is a power supply device that converts the voltage of the automobile battery into the voltage required for the recording device.

As described above, according to the present invention, it is possible to save the driver's effort in keeping a daily report and create a daily driving report with fewer errors, and it is also possible to create a driving record that is easy to read. This has the effect of reducing driver effort, speeding up administrative work, and improving reliability.
