Reference). Further, Japanese Utility Model Application Laid-Open No. 63-192862 discloses a technique for outputting operation information from a sensor to a detachably inserted storage medium via a repeater. However, this technique is intended to reduce the number of components, and it is not possible to quickly change and improve the system and improve the operation management.

Further, in the conventional apparatus, a terminal, that is, a numeric keypad, for a driver to input operation data such as work information, is exclusively used for each apparatus, and cannot be used for other purposes. . Therefore, it is necessary to add or change the input of work or vehicle operation information (loading, refueling, inspection and maintenance, payment of expressway tolls, breaks, hand waiting, etc.) that matches the intention of the user (operation manager, etc.). However, complicated operations such as writing a machine program into a ROM were necessary, and were not enough to manage and improve the operation.

2 and a power supply 23.

The control device main body 1 includes sensors 20 to
An arithmetic processing unit 2 for inputting vehicle information from the control unit 21 through the input interface 5 and performing arithmetic processing; a ROM (ROM) 3;
A RAM (RAM) 4 and a communication interface 6 to which a terminal 10 is connected are provided. The terminal 10 is composed of a known electronic organizer, and the original electronic organizer 11 and the display 12, an input unit 13 for each item indicating an operation state, and data indicating a traveling state and an operation state are transmitted from the apparatus body 1. And a storage unit 14 for inputting and storing.

FIG. 2 shows the arrangement of the function keys A to J of the input unit 13, and FIG. 3 shows the names of the function keys A to J and the ID code.

The outline of the control mode of the apparatus main body 1 will be described. When the power supply 23 is turned on, a main process (FIG. 6) is started, and communication becomes possible when the ignition key is turned off.
The vehicle conditions that have been input to the terminal 10 in advance, that is, values such as a gear ratio and a tire diameter, are received, and initialization is performed. The recording of the operation data is started by the interruption process (FIG. 7) when the ignition key is turned on, and the data is stored in the RAM 4.
In the setting form F (FIG. 5). At the end of operation,
The ignition key is turned off, the terminal 10 is connected, the recording is terminated by a termination command from the terminal 10, and the operation data is transferred to the terminal 10. Furthermore, initialization is performed in preparation for the next operation. On the other hand, Terminal 10
Then, while the operation data is being recorded, input of operation information for operation management is performed. After receiving the operation data from the apparatus main body 1, display and correction of the operation data and work information are performed.

The data of the terminal 10 recorded in the apparatus main body 1 is displayed on the display 12 as it is, but as shown in FIG. 4, personal data is transmitted through an input / output device (I / O) and a reader / writer (R / W) 16. It is connected to a computer 17 and used for analysis of actual operation status and operation management / improvement through a disk file 18 and a display 19.

FIG. 6 shows a main processing flow.

The apparatus main body 1 enables interruption (step S1), and determines whether or not the signal from the ignition key ON / OFF sensor 22 is OFF (step S2).
If YES, communication with the terminal 10 is permitted (step S3), and it is determined whether or not there is a command to receive individual information of the vehicle (step S4). In the case of NO, that is, during recording, the process returns to step S2. If the result is YES, the real timer in the entire apparatus 1 is stopped (step S5), and interruption is disabled (step S5).
6). Next, it is determined whether or not the transmission is performed (step S7).
In the case of NO, the vehicle condition and time data are received (step S8) and sent to step S11, and if YES,
The failure self-diagnosis is performed (step S9), and the recorded data and the diagnosis result data are transmitted to the terminal 10 (step S9).
10), proceed to step S11. In step S11, system variables such as a gear ratio and a tire diameter are initialized, and then a real timer is started by adjusting the time (step S12), and an interrupt is enabled (step S11).
13) Return.

FIG. 7 shows a flow of a sampling process of the interrupt. It is determined whether or not the ignition key has changed (step S20). If there is no change, the process proceeds to step S27. Is changed from OFF to ON (step S21). If YES, it is determined whether or not the vehicle is running (step S22). If YES, the parking flag is set to O.
FF is performed (step S23), and the parking time counter value is written into the ram 4 (step S24), and step S27 is performed.
Move on to When step S21 is NO, that is, when the ignition key changes from ON to OFF,
The parking counter is initialized, the parking flag is turned on (Step S25), and the routine goes to Step S27. If NO in step S22, that is, if the operation has ended, the system flag is set to “recording” (step S26), and the process proceeds to step S27. In step S27, it is determined whether or not the ignition key is ON. In the case of NO, the process proceeds to step S35, and in the case of YES, it is determined whether or not the specified maximum speed is exceeded (step S28). If NO, the process proceeds to step S30, and if YES, the time, time, and distance are counted and written (step S2).
9) Move to step S30. In step S30, it is determined whether or not the specified maximum number of revolutions has been exceeded.
If the determination is NO, the process proceeds to step S32. If the determination is YES, the time, the time, and the number of revolutions are counted and written (step S31), and the process proceeds to step S32. Step S3
In 2, the travel distance is calculated, then the speed at the sampling time is calculated (step S32a), the maximum speed is determined, and the RAM is saved (step S32b). Further, it calculates how fast and how often the vehicle ran (step S
33) Count how often the vehicle has traveled at the specified range speed (step S34), and determine whether a set sampling time of, for example, 5 minutes has elapsed (step S35). In the case of NO, the interruption ends, and in the case of YES, it is determined whether or not the vehicle is parked (step S36). N
In the case of O, for example, the maximum speed for 5 minutes, the ON / OFF state of the ignition key, and the running distance are written (step S37). When the interruption is over and the answer is YES, the parking time is counted, for example, for 5 minutes (step S3).
8) End the interrupt.

FIG. 8 shows a processing flow in the terminal 10. The driver turns on the power supply 23 and inputs one of the function keys A to P (step S4).
1) Write the ID code of the function key (step S42), and write the time (step S4).
3) When the written work is started (YES in step S44), a work start time is input (step S51),
The power supply 23 is turned off to finish. When the work is completed (step S44 is NO and step S45 is YES),
The work end time is input (step S46), and the
Command (step S47), and receives the recorded data from the apparatus main body 1 (step S48). Therefore, the content input with the function key is matched with the recorded data (step S49), and if there is an error, the error is corrected (step S50), and the power is turned off to end.
