[0006]

[0007]

In the operation recording apparatus configured as described above, the apparatus is started up when the power is turned on, and when the sampling time is changed, an input is made from the input unit.
When the ignition key is in the OFF state, the sampling time is input to the ram of the apparatus main body and stored together with data necessary for calculation from the terminal. When the ignition key is turned on, acquisition of operation data is started, and if a sampling time exists in the ram, sampling is performed at the sampling time. And
When there is no set value of the sampling time in the RAM, sampling is performed using the default value (specified value) stored in the ROM. Therefore, by inputting the sampling time to the ram from the input unit, data can be acquired at an arbitrarily designated sampling time, so that the analysis of the running state and work can be performed accurately and efficiently. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, an operation recording apparatus includes an apparatus main body 1, a terminal 10 connectable to the apparatus main body 1, a speed sensor 20, an engine rotation sensor 21, an ignition key ON / OFF sensor connected to the apparatus main body 1. 22
And a power supply 23.

The apparatus main body 1 includes sensors 20 to 21.
Processing unit 2 for inputting vehicle information from the vehicle through input interface 5 and performing arithmetic processing, ROM (ROM) 3 for storing a program for arithmetic processing and a predetermined value of sampling time, setting value of sampling time, etc. (RAM) 4 for storing the information and a communication interface 6 to which the terminal 10 is connected. 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.

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. 4) is started. The setting of the sampling time is performed by inputting the value into the terminal 10 and receiving the vehicle information together with the vehicle information from the terminal 10 when the ignition key is turned off, and storing and holding the same in the ram 4. Sampling of the operation state of the vehicle is performed according to an interruption process (FIG. 5) when the ignition key is turned ON, and data is stored in the ram 4 in a setting form (FIG. 3). When the set value of the sampling time on the ram 4 exists, sampling is performed with that value, and when it does not exist, the sampling is performed with the ROM 3 default value (default value).

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. 2, personal data is transmitted via 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. 4 shows a main processing flow.

The apparatus main body 1 enables an interrupt (step S1), and determines whether or not a 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. 5 shows a flow of an interrupt sampling process. It is determined whether or not the ignition key has changed (step S20). If it has not changed, the process proceeds to step S27. If it has changed, the ignition key has changed. Is changed from OFF to ON (step S21). If YES, it is determined whether or not recording is in progress (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).

Next, it is determined whether or not there is a set value of the sampling time (step S35).
It is determined whether or not the set sampling time (for example, 5 minutes) has elapsed (step S36). If NO, it is determined whether or not the set sampling time of the default value on ROM 3 has elapsed. In the case of NO in both steps S36 and S37, the interruption ends, and in the case of YES,
It is determined whether the vehicle is parked (step S38). In the case of NO, for example, the maximum speed for 5 minutes, the ON / OFF state of the ignition key and the running distance are written (step S39), and the interruption is ended. If the answer is YES, the parking time is counted by 1 for example in 5 minutes ( Step S40),
End the interrupt.
