BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below along with preferred embodiments. It should be noted that the present invention is not limited to the embodiments described below, and can be modified as appropriate without departing from the gist of the present invention. In addition, in the embodiments shown below, there are places where illustrations and explanations of some configurations are omitted, but the details of the omitted technologies are provided within the scope that does not cause contradiction with the contents explained below. , Needless to say, well-known or well-known techniques are applied as appropriate.

FIG. 1 is a block diagram showing the operation recording device according to the embodiment of the present invention. As shown in FIG. 1, the operation recording device 1 is mounted on a vehicle and records vehicle operation data (for example, vehicle operation information such as vehicle speed and engine speed). The operation data is recorded, for example, in an operation card (a card having a recording medium) inserted in the operation recording device 1 or in a data recording unit 13 which will be described later. The operation card is carried by the driver of the vehicle. The operation card is brought to a management office or the like by the driver after the end of driving, and is set in the driving evaluation device. When the operation card is set, the operation evaluation device reads operation data and performs evaluation based on the read operation data.

Such an operation recording device 1 includes a CPU (Central Processing Unit) 11, a setting program storage unit 12, a data recording unit (internal memory) 13, a data processing unit 14, an information storage unit 15, a speed I / F (Interface) 16 , an engine I/F 17 , a power I/F 18 and a card connector 19 . Furthermore, the operation recording device 1 includes an LCD (Liquid Crystal Display) 20 , an audio output section 21 , and an other vehicle copy processing section 22 .

The CPU 11 comprehensively controls each part of the operation recorder 1 . The setting program storage unit 12 stores a program for the CPU 11 of the operation recorder 1 to implement each function. The data recording unit 13 is a non-volatile memory or the like in which operation data is recorded. Operation data of other vehicles are also copied to the data recording unit 13 as will be described later.

The data processing unit 14 serves as a work area for processing operation data. The information storage unit 15 stores the vehicle code of the vehicle in which the operation recording device 1 is mounted, the driver code indicating the authorized driver, the model code indicating the model of the operation recording device 1, and the like.

A speed I/F 16 receives a speed pulse from a vehicle speed sensor attached to the vehicle. The speed I/F 16 is connected to the CPU 11 and supplies the input speed pulse to the CPU 11 . The CPU 11 inputs a speed pulse through the speed I/F 16 and grasps the speed of the own vehicle.

The engine I/F 17 receives engine pulses from an engine speed sensor attached to the vehicle. The engine I/F 17 is connected to the CPU 11 and supplies input engine pulses to the CPU 11 . The CPU 11 receives an engine pulse through the engine I/F 17 and grasps the engine speed of the own vehicle.

The power supply I/F 18 is an input unit that receives power supply from the vehicle battery. The card connector 19 is a card insertion part into which a service card owned by a driver (for example, a taxi driver or a delivery company driver) is inserted. Since the operation card is inserted into the card connector 19 during business hours, the operation data is recorded not only in the data recording unit 13 but also in the operation card.

The LCD 20 is a display unit for providing information to the driver through image display. The voice output unit 21 issues a warning or the like when it is determined that the driver is driving in a manner that deviates from predetermined safe driving conditions.

The other vehicle copy processing unit 22 is a functional unit that copies the operation data of the other vehicle in order to save the operation data before the transfer due to the loss of the operation card. The other vehicle copy processing section 22 includes a first determination section (first determination means) 22a, a second determination section (second determination means) 22b, and a memory control section (memory control means) 22c.

The first judging section 22a judges, when an operation card is inserted into the card connector 19, whether operation data of other vehicles is recorded in the inserted operation card. When the first determination unit 22a determines that the operation data of the other vehicle is recorded, the second determination unit 22b determines that the operation data of the other vehicle is recorded by the operation recording device 1 of a different model. It determines whether

Here, in this embodiment, the operation data includes 1) vehicle code, 2) model code, and 3) physical data such as vehicle speed during operation. Of these, 1) vehicle code and 2) model code are information that can be read not only between operation recorders 1 of the same model but also between operation recorders 1 of different models. As for 3) physical data, different formats are often adopted for operation recorders 1 of different models.

The first determination unit 22a determines whether the operation data of other vehicles is recorded based on the vehicle code of such operation data. That is, the first determination unit 22a reads the vehicle code of the operation data recorded in the operation card and determines whether the vehicle code matches the vehicle code stored in the information storage unit 15. FIG. The first determination unit 22a determines that the operation data of the other vehicle is not recorded in the operation card when the vehicle codes match, and the operation data of the other vehicle is recorded in the operation card when the vehicle codes are different. It is determined that

The first determination unit 22a determines that the operation data of other vehicles is not recorded in the operation card even when the operation data is not recorded in the operation card and there is no vehicle code to be read.

The second determination unit 22b determines whether the operation data of the other vehicle was recorded by the operation recording device 1 of a different model based on the model code of the operation data as described above. That is, the second determination unit 22b reads the model code of the operation data recorded in the operation card and determines whether it matches the model code stored in the information storage unit 15. FIG. When the model codes match, the second determination unit 22b determines that the operation data of the other vehicle recorded in the operation card is recorded by the same model, and when the model codes are different, the other vehicle are recorded by a different model.

The memory control unit 22c is a functional unit that copies operation data of other vehicles to the data recording unit 13. FIG. In this embodiment, the storage control unit 22c stores the operation data of the other vehicle as data when the second determination unit 22b determines that the operation data of the other vehicle was recorded by the operation recording device 1 of the same model. Store in the recording unit 13 . On the other hand, when the second determination unit 22b determines that the operation data of the other vehicle was recorded by the operation recording device 1 of a different model, the storage control unit 22c stores the operation data of the other vehicle in the data recording unit. 13 is prohibited.

Thus, in this embodiment, the storage control unit 22c does not execute the copy process when the operation data of the other vehicle is recorded by the operation recording device 1 of a different model. This prevents the operation data from being damaged in the data recording section 13 by copying the data of a different format like the 3) physical data of the operation data described above.

Next, an overview of the operation of the operation recorder 1 according to this embodiment will be described. FIG. 2 is a conceptual diagram showing an overview of the operation of the operation recorder 1 according to this embodiment.

As indicated by symbol A in FIG. 2, the driver first inserts the operation card into the operation recording device 1a before changing trains, and exit processing is performed. After that, the vehicle will go out for business outside the office premises, etc., and the operation data will be recorded in the operation recording device 1a and the operation card before the transfer. Next, the vehicle returns to the office premises or the like, and the warehousing process is performed. Next, the operation card is taken out from the operation recording device 1a.

After that, as indicated by symbol B, the driver inserts the operation card into the operation recording device 1b after the transfer. It is assumed that this operation recording device 1b is of the same model as the operation recording device 1a before the transfer. In this case, the operation recording device 1b after the transfer determines that the operation data of the other vehicle is recorded in the operation card by the first determination unit 22a. Next, the second determination unit 22b determines that the operation data of the other vehicle has been recorded by the operation recording device 1a of the same model as the self, and the storage control unit 22c causes the data recording unit 13 to copy the operation data of the other vehicle. . After that, the leaving process is performed, and the operation data at the time of business is recorded in the operation recording device 1b and the operation card after the transfer. Next, the vehicle returns to the office premises or the like, and the warehousing process is performed. Next, the operation card is taken out from the operation recording device 1b.

In this case, for example, if the driver loses the operation card, a backup card is inserted into the operation recording device 1b. The contents stored in the data recording section 13 are copied to the backup card. Therefore, as shown in FIG. 2, the operation data before the transfer and the operation data after the transfer are stored in the backup card.

On the other hand, as indicated by symbol C, it is assumed that the operation card is inserted into the operation recorder 1b of a different model depending on the driver. In this case, the operation recording device 1b after the transfer determines that the operation data of the other vehicle is recorded in the operation card by the first determination unit 22a. However, the second determination unit 22b determines that the operation data of the other vehicle is not recorded by the operation recording device 1a of the same model as its own. Therefore, the storage control unit 22c prohibits the process of copying the operation data of the other vehicle to the data recording unit 13. FIG. After that, the leaving process is performed, and the operation data at the time of business is recorded in the operation recording device 1b and the operation card after the transfer. Next, the vehicle returns to the office premises or the like, and the warehousing process is performed. Next, the operation card is taken out from the operation recording device 1b.

In this case, for example, if the driver loses the operation card, a backup card is inserted into the operation recording device 1b. Only operational data will be stored.

Next, a data storage method of the operation recording device 1 according to this embodiment will be described. FIG. 3 is a flowchart showing a data storage method of the operation recorder 1 according to this embodiment. Note that the processing shown in FIG. 3 is repeatedly executed until the power of the operation recorder 1 is turned off.

First, as shown in FIG. 3, the CPU 11 of the operation recorder 1 determines whether the operation card is inserted into the card connector 19 (S1). If the operation card has not been inserted (S1: NO), the CPU 11 repeats this process until it is determined that the operation card has been inserted.

When the operation card is inserted (S1: YES), the CPU 11 determines whether the leaving process has been completed (S2). In this process, the CPU 11 determines whether the leaving process is completed when, for example, an operation card storing a valid driver code is inserted into the card connector 19 and the leaving operation is performed. If the leaving process has not been completed (S2: NO), the CPU 11 repeats this process until it determines that the leaving process has been completed.

When the leaving process is completed (S2: YES), the first determination unit 22a determines whether the operation data of the other vehicle is recorded in the operation card (S3). In this process, the first determination unit 22a determines whether the operation data of the other vehicle is recorded in the operation card based on whether the vehicle code in the operation data and the vehicle code stored in the information storage unit 15 match. determine if there is

If the operation card does not record the operation data of the other vehicle (S3: NO), the process proceeds to step S7. On the other hand, when the operation data of the other vehicle is recorded in the operation card (S3: YES), the second determination unit 22b determines whether the operation data of the same model is recorded (S4).

If the operation data of the same model is recorded (S4: YES), the memory control unit 22c copies the operation data of other vehicles recorded in the operation card to the data recording unit 13 (S5). After that, the storage control unit 22c determines whether copying is completed (S6). If copying is not completed (S6: NO), this process is repeated until copying is completed. If the copy process is completed (S6: YES), the process proceeds to step S7.

If the operation data of the same model is not recorded (S4: NO), that is, if the operation data of a different model is recorded, the storage control unit 22c does not execute the copy process, and the process proceeds to step S7. Transition.

In step S7, the operation recorder 1 performs data processing and recording processing during leaving the garage (S7). After that, the process moves to step S1.

As described above, according to the operation recording device 1 and the data storage method thereof according to the present embodiment, when it is determined that the operation data of another vehicle is not recorded by the operation recording device 1 of the same model, To inhibit the processing of storing operation data of a vehicle in a data recording unit 13, thereby preventing data in a different format from being copied, and reducing the possibility of damage to the operation data in the data recording unit 13.例文帳に追加can be done.
