It has a database 29.

  The CPU 11 comprehensively controls each part of the digital tachograph 10, and processes and records the speed, the engine speed, and the captured image as operation data in the recording unit 17. The memory 26 stores an operation program executed by the CPU 11. The memory 26 stores limit values such as speed and engine speed. The recording unit 17 records operation data including speed, engine speed, captured image, inter-vehicle time, brake reaction timing, and the like.

  The card I / F 18 (reading unit) has a card slot 18a (insertion unit), is connected to various cards inserted into the card slot 18a, and transmits and receives data. In this embodiment, a crew member authentication card 55 (external recording medium) possessed by a crew member is inserted into the card slot 18a so as to be freely inserted and removed. FIG. 2 is a table showing registration contents of the crew member authentication card 55. In the crew member authentication card 55, identification information of two crew members consisting of a regular crew member and a secondary crew member is registered. Note that the identification information of three or more crew members may be registered. In this embodiment, a three-digit identification number (ID number) consisting of numerals and alphabets is used as identification information.

In addition, information such as the name, function classification, identification number, and driving evaluation of each crew member is registered in the crew member authentication card 55. In this embodiment, a contact type card such as a magnetic recording card or an IC card inserted into a card slot is used as a crew member authentication card.
Here, if you start running with the Crew Authentication Card mounted on the digital tachograph, the temperature inside the digital tachograph housing that is running will rise, and this temperature rise may cause the card itself to deteriorate and shorten the card life. is there. For this reason, as described later, it is desirable to remove the crew member authentication card from the card slot after the identification number has been read.

  Instead of using a contact card inserted into a card slot and connectable to the card I / F, a non-contact IC card capable of short-range wireless communication may be used as a crew member authentication card. As the short-range wireless communication, a wireless communication method such as near infrared, Bluetooth (registered trademark), Felica (registered trademark), or the like can be employed.

Further, a memory card (not shown) capable of transferring operation data once recorded in the recording unit 17 or directly recordable is inserted into the card slot 18a of the card I / F 18 so as to be freely inserted and removed.
A speaker 20 (notification unit) for notifying various information is connected to the audio I / F 19. The RTC 21 measures the current time.

A button set 30 is connected to the button input I / F 22. The button set 30 (operation unit) includes a crew member switching button 31, a setting button 32, an UP button 33, and a DOWN button 34. The crew member switching button 31 is a button for switching selection of two crew members registered in the crew member authentication card 55. The setting button 32 is a button for confirming various settings and selections. The UP button 33 is a button for switching selection to a previous crew member when selecting a plurality of crew members included in a crew member ID selection screen displayed on a liquid crystal display (LCD) 28 described later. Similarly, the DOWN button 34 is a button for switching selection to the next crew member.
A liquid crystal display 28 is connected to the display I / F 23, and the display I / F 23 controls the display operation of the liquid crystal display 28. The LED display unit 27 displays the state of communication and operation.

  In the crew ID number database (DB) 29, identification numbers (ID numbers) of many crew members are registered in advance. In addition, in the crew ID number database 29, the identification numbers of a plurality of crew members (for example, 20 crews) who have boarded up to the last time are set to be readable as a history of boarding the vehicle.

Further, the digital tachograph 10 includes a speed I / F 12A, an engine rotation I / F 12B, a camera input I / F 13, a sensor input I / F 14, a GPS receiving unit 15, a CAN_I / F 16, a communication unit 24, and a power supply unit 25.
A speed pulse representing a vehicle speed is input from the vehicle speed sensor to the speed I / F 12A. The engine rotation I / F 12B receives a rotation pulse representing the engine speed from the engine speed sensor. A camera 52 that images the front of the vehicle is connected to the camera input I / F 13. Signals such as a brake SW 54 that is turned on when the brake pedal is pressed by the crew member, a temperature sensor that detects the engine temperature, a fuel sensor that detects the fuel amount, and a blinker SW are input to the sensor I / F 14.

  The GPS receiver 15 is connected to the GPS antenna 15a and acquires the current position (GPS information). Various devices in the vehicle connected to a CAN (Controller Area Network) standard network are connected to the CAN_I / F 16 so that various data such as speed, engine, and fuel amount can be communicated. The communication unit 24 performs wide area communication via a wide area communication network such as a wireless communication line (for example, a 3G / LTE line) and a packet communication network such as the Internet. The power supply unit 25 supplies power to each unit of the digital tachograph 10 when the ignition switch is turned on.

  FIG. 3 is a diagram showing the appearance of the digital tachograph 10. A liquid crystal display 28, a button set 30, a speaker 20, and a card slot 18a are disposed on the front surface of the housing 10A of the digital tachograph 10. The button set 30 includes the crew switch button 31, the setting button 32, the UP button 33, and the DOWN button 34 described above.

  A card such as a crew member authentication card is removably inserted into the card slot 18a. The liquid crystal display 28 displays a crew member ID selection screen 65 (see FIG. 4). FIG. 4 is a diagram showing a crew ID selection screen 65 displayed on the liquid crystal display 28 of the digital tachograph 10.

  On the crew member ID selection screen 65, identification numbers of a plurality of crew members registered in advance (for example, all crew members in the company) are arranged in the vertical direction and the horizontal direction. As an example, the identification numbers “43d”, “1cb”, “b32”,..., “210”, “e2e”,. If the identification number does not fit on one screen, a scroll bar 66 is displayed on the right side of the screen. For example, after the user presses a predetermined button, the UP button 33 or the DOWN button 34 is pressed and the slider 66a of the scroll bar 66 is slid to scroll the crew member ID selection screen 65 in the vertical direction in the figure. Thus, an undisplayed identification number can be displayed. Also, a message 67 “Please insert a crew member authentication card” prompting the insertion of the crew member authentication card 55 is displayed at the bottom of the crew member ID selection screen 65.

  The operation of the digital tachograph 10 having the above configuration will be described. FIG. 5 is a flowchart showing a procedure for inputting the identification number of the crew member. The operation of inputting the identification number is performed before starting the recording of operation data. The CPU 11 displays the crew ID selection screen 65 (see FIG. 4) on the liquid crystal display 28 (S1). This makes it possible to select and set one identification number from among a plurality of crew member identification numbers displayed on the liquid crystal display 28. In this case, the crew member presses the setting button 32 in a state where one identification number is selected, so that this selection is confirmed and the identification number is set in the digital tachograph 10. Therefore, the CPU 11 functions as a setting unit.

  The CPU 11 determines whether or not the UP button 33 is pressed by the crew before the setting button 32 is pressed by the crew (S2).

  When the UP button 33 is pressed, the CPU 11 displays the crew member ID selection screen 65 in a state in which the identification number that is one order prior from the present is selected (S3). Then, the CPU 11 rings the speaker 20 so as to notify the name of the target crew member (S4).

  The CPU 11 determines whether or not the setting button 32 has been pressed (S5). If the setting button 32 is not pressed, the process returns to step S1. On the other hand, when the setting button 32 is pressed, the CPU 11 outputs a message indicating the start of recording from the speaker 20 (S6). That is, the speaker 20 notifies a message to record with the name of the target crew member. For example, a message “Start recording of Mr. XX” is notified from the speaker 20 (see FIG. 3).

  And CPU11 starts the recording of operation data (S7). Thereafter, the CPU 11 ends this operation. In the recording of operation data, the CPU 11 determines the speed input via the speed I / F 12A, the engine speed input via the engine rotation I / F 12B, the current vehicle position obtained from the GPS receiver 15, and the like. Information is recorded in the recording unit 17 in time series.

  On the other hand, when the UP button 33 is not pressed in step S2, the CPU 11 determines whether or not the DOWN button 34 is pressed (S8). When the DOWN button 34 is pressed, the CPU 11 displays the crew member ID selection screen 65 in a state in which the identification number one order after the present is selected (S9). Thereafter, the CPU 11 proceeds to the process of step S4 and performs the same process.

  On the other hand, if the DOWN button 34 is not pressed, the CPU 11 determines whether or not the crew member authentication card 55 has been inserted into the card slot 18a of the card I / F 18 (S10). When the crew member authentication card 55 is not inserted, the CPU 11 returns to the process of step S1 and causes the liquid crystal display 28 to continue displaying the crew member ID selection screen 65.

  On the other hand, when the crew member authentication card 55 is inserted in step S10, the CPU 11 proceeds to the process of step S6, and outputs a message indicating the above-described recording start from the speaker 20.

  As described above, in the digital tachograph 10, when setting the identification number of the crew member, the crew member simply inserts the crew member authentication card 55 owned by the crew member into the card slot 18a disposed on the front surface of the housing 10A. The crew identification number stored in the crew authentication card 55 can be read into the digital tachograph 10. Thereby, the operation of selecting the identification number of the crew member from the crew member ID selection screen can be saved, and the input operation of the crew number is simplified.

In addition, by performing an operation of selecting one identification number from among a number of identification numbers registered on the crew ID selection screen 65 displayed on the liquid crystal display 28, the crew identification card is placed in the card slot. Even if it is not inserted, the crew can input their identification number using the crew ID selection screen. Therefore, the crew member authentication card is placed in a place where it is difficult to reach and it is possible to input the crew member identification number even in a situation where it is difficult to use. Alternatively, even if part of the crew authentication card is damaged or the data of the identification information is lost, it is also possible to manually select the identification information from the crew ID selection screen. is there. Thereby, it is possible to prevent the recording of the operation data from being started without knowing the identification number of the crew member.
(Second Embodiment)

  In the second embodiment, countermeasures that can occur by using a crew member authentication card will be described. Since the digital tachograph of the second embodiment has the same configuration as that of the first embodiment, the same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  6 and 7 are flowcharts showing the procedure for inputting the crew member identification number in the second embodiment. About the same step process as the said 1st Embodiment, the description is abbreviate | omitted by attaching | subjecting the same step number.

  When the crew member authentication card 55 is inserted into the card slot 18a disposed on the front surface of the housing 10A of the digital tachograph 10 in step S10, the CPU 11 determines whether or not the crew member authentication card 55 is normal, that is, the crew member authentication card. It is determined whether or not the crew member identification number stored in 55 can be read (S11).

  As a result of this determination, the identification number of the crew member stored in the crew member authentication card 55 can be read. If the crew member authentication card 55 is normal, the CPU 11 presses the crew member switch button 31 by the crew member, and the crew member switching operation is performed. It is determined whether or not the operation has been performed (S12). When the crew member switching operation is performed, the CPU 11 switches from one crew member to the other crew member among the two crew members stored in the crew member authentication card 55 (S13), and sets the identification number of the crew member after the switching. Read (S14). On the other hand, if the crew member switching operation is not performed in step S12, the CPU 11 reads the crew member identification number in step S14 without switching the crew member.

  After reading the identification number, the CPU 11 determines whether or not the crew member authentication card 55 has been removed from the card slot 18a (S15). When the crew member authentication card 55 has not been removed from the card slot 18a, the CPU 11 issues an alarm for prompting removal (S16). In this alarm, the CPU 11 makes a predetermined alarm sound for the speaker 20, for example. Alternatively, the CPU 11 may turn on the LED display unit 27 so as to indicate an alarm together with the alarm sound or instead of the alarm sound. In addition, the CPU 11 may display on the screen of the liquid crystal display 28 to prompt the crew member authentication card 55 to be removed. On the other hand, if the crew member authentication card 55 has been removed from the card slot 18a, the CPU 11 proceeds directly to the process of step S6. The processing after step S6 is as described above.

  If the crew member identification number stored in the crew member authentication card 55 cannot be read in step S11 and the crew member authentication card 55 is abnormal, the CPU 11 uses the speaker 20 to indicate that the crew member authentication card 55 is abnormal. (S17). Here, as an abnormality of the crew member authentication card, there is a case where the crew member authentication card 55 is partially damaged or stored data is erased. In this case, the CPU 11 returns to the process of step S1.

  Note that the confirmation of the extraction of the crew member authentication card in step S15 and the warning for prompting the extraction when not extracted in step S16 may be performed after notifying the name of the target crew member in step S6. After confirming that the crew member identification number has been set, the crew member authentication card can be removed.

  In the digital tachograph of the second embodiment, if the crew member authentication card is not extracted after reading the identification number, an alarm to that effect is given, so that the crew member can immediately notice and remove the crew member authentication card. Thereby, it is possible to prevent forgetting to remove the crew member authentication card. In addition, it is possible to prevent the crew member authentication card from being inserted into the card slot during traveling, and the card itself from being deteriorated due to the temperature rise inside the housing, thereby shortening the life of the crew member authentication card.

  In addition, since one of the two crew members stored in the crew member authentication card can be selected, the crew member can be replaced with a simple operation. Thereby, the operation data can be recorded with the correct identification number of the crew member.

  Further, when the crew member authentication card is abnormal, the fact is notified, so that the crew member can notice the abnormality of the crew member authentication card. Even in this case, the crew member can manually perform an operation of selecting his / her identification number displayed on the crew member ID selection screen as usual. Thereby, it is possible to prevent the recording of the operation data from being started without knowing the identification number of the crew member.

The technical scope of the present invention is not limited to the embodiment described above. The above-described embodiments can be accompanied by various modifications and improvements within the technical scope of the present invention.
For example, in the above embodiment, when setting the identification information of the crew member, after the crew ID selection screen is first displayed, the selection operation by the crew member using the setting button or the like, or the crew member authentication card insertion operation is performed. Operations may be performed in the following order. That is, a screen prompting the insertion of a crew member authentication card is displayed first, and when the crew member authentication card is not inserted even after waiting for a predetermined time, a crew member ID selection screen is displayed and a selection operation by a crew member using a setting button or the like is performed. You may be made to be. Thereby, the crew member's operation can be guided to the insertion of the crew member authentication card with an easy input operation.

Moreover, although the case where it applied to a digital tachograph as a vehicle-mounted apparatus was shown in the said embodiment, you may apply to various apparatuses, such as a drive recorder and a car navigation apparatus.
