Description

The present invention relates to the operation recording device and the data reading how to record operational data to the storage device.

  Conventionally, a digital tachograph that is mounted on a vehicle and records operation data such as a traveling speed, a traveling time, and a traveling distance of the vehicle is known. It is possible to insert a recording medium such as an IC memory card into the digital tachograph and suck up the recorded operation data. The extracted operation data is read by a data processing device on the office side, and the operation data is analyzed by analysis software.

  FIG. 9 is a flowchart showing a conventional procedure for recording operation data and writing to a recording medium. The digital tachograph waits until the ignition key (IGN) is turned on (step S101). When the IGN is turned on, the digital tachograph waits until an IC memory card (recording medium) is inserted (step S102).

  When the recording medium is inserted, the digital tachograph determines whether or not there is driver information on the recording medium (step S103). If there is no driver information, the digital tachograph generates an error (step S112) and ends the process.

  On the other hand, if there is driver information, the digital tachograph registers the driver information in a memory (SRAM) and makes it possible to take out the recording medium (step S104). Thereafter, the digital tachograph starts recording operation data such as travel speed and engine speed in a memory (SRAM) (step S105).

  The digital tachograph determines whether or not the data capacity of the work area of the memory (SRAM) is full (step S106). If it is not full, the digital tachograph returns to the process of step S105. On the other hand, when it becomes full, the digital tachograph moves the operation data stored in the memory (SRAM) to the backup memory (FROM) (step S107).

  The digital tachograph determines whether or not the vehicle is stopped (stopped) (step S108). If the vehicle is not stopped, the process returns to step S105. On the other hand, when the vehicle is stopped, the digital tachograph determines whether or not the above-described recording medium is inserted again (step S109). If not inserted, the digital tachograph returns to the process of step S105. On the other hand, when the recording medium is inserted, the digital tachograph writes (discharges) the operation data from the time when the driver information is registered (at the timing “a”) until the vehicle stops (at the timing “b”) to the recording medium. Step S110). Thereafter, the digital tachograph makes it possible to take out the recording medium (step 111). When the recording medium is taken out, the process returns to step S102.

  As described above, in the conventional digital tachograph, it is possible to suck up only the previous operation data from the registration of the driver information to the insertion of the recording medium on which the driver information is recorded after stopping. It is. Thereby, the siphoning time can be shortened.

  Further, as a conventional operation recording apparatus, an in-vehicle apparatus that records operation data collected for each operation of a vehicle on a recording medium is known (see Patent Document 1).

JP 09-81816 A

  However, the conventional operation recording apparatus has the following problems, and an improvement has been demanded. That is, in the conventional digital tachograph, the recording medium for sucking up the operation data after the end of traveling is only one type for the driver. For this reason, in some cases, there is a possibility that the operation data may be left behind.

  For example, assume that there are two drivers driving the same car. If the driver A who was driving first did not download the operation data when the driver changed, the next driver B could only download his own operation data. The operation data will remain.

  Also, when the vehicle is returned, the crew member who was on the vehicle did not press the write button, so the operation data for that ride was not recorded on the crew card, and the crew member of the next crew member who got on that vehicle The operation data may remain on the card without being recorded.

The operation recording apparatus of this embodiment is applied to a digital tachograph that is mounted on a vehicle and records operation data of the vehicle.

  FIG. 1 is a block diagram showing a configuration of a digital tachograph 10 in the embodiment. The digital tachograph 10 includes a CPU 11, a data processing unit 12, a data recording unit 13, an LCD 14, a buzzer 15, a printer 16, a recording medium connector 17, a power supply unit 18, an operation unit 22, an RTC 23, a speed interface (I) connected to the CPU 11. / F) 19, engine I / F 20, and reception I / F 21.

  The CPU 11 controls the entire digital tachograph, has a built-in ROM, RAM, etc., and executes an operation program stored in the ROM.

  Based on the speed pulse signal detected by the vehicle speed sensor 32 and the engine rotation pulse signal detected by the engine speed sensor 33, the data processing unit 12 receives various data such as the vehicle speed, the engine speed, and the travel distance. To process.

  The data recording unit 13 is a data memory (SRAM) 13a used as a work area in which operation data is recorded. When the data capacity of the data memory 13a is full, the operation data recorded in the data memory 13a is moved. And a backup memory 13b used as a backup and a table memory 13c in which driver information is set in advance. The backup memory 13b has a larger data capacity than the data memory 13a. The data recording unit 13 records operation data such as position information, travel distance, vehicle speed, engine speed, operation time, and battery voltage. Of course, the media types of the data memory 13a, the backup memory 13b, and the table memory 13c may be different. For example, the data memory 13a may be a RAM, the table memory 13c may be a ROM, and the backup memory 13b may be a hard disk drive. In the present embodiment, a static RAM (SRAM) is used for the data memory 13a, and a flash memory (FROM) is used for the backup memory 13b.

  The LCD 14 displays various types of information such as the running state, time, and emergency messages. The buzzer 15 issues voice guidance such as dangerous driving conditions, uneconomical driving, and abnormal conditions to the crew (driver) as an alarm. The printer 16 prints operation data and the like.

  A recording medium 31 can be freely connected to the recording medium connector 17. As a recording medium, an IC memory card, a USB (Universal Serial Bus) memory, or the like can be used.

  A vehicle speed sensor 32 is connected to the speed I / F 19 and a speed pulse signal generated by the vehicle speed sensor 32 is input. The vehicle speed sensor 32 is composed of a rotary encoder, and generates a pulse signal of a number corresponding to the transmission speed of the rear wheel (drive wheel) as a pulse signal for calculating a travel distance, and outputs it as a speed pulse signal.

  An engine speed sensor 33 is connected to the engine I / F 20, and an engine speed pulse signal generated by the engine speed sensor 33 is input thereto. Among engine speed sensors, there are sensors that mechanically detect rotation of the camshaft of the engine to generate a pulse signal, and sensors that electrically detect an applied voltage to the spark plug to generate a pulse signal.

  A GPS receiver 37 is connected to the reception I / F 21. A GPS (Global Positioning System) receiver 37 is attached to the vehicle, receives radio waves from a plurality of GPS satellites, and outputs a signal representing coordinates (GPS coordinates) of the current position of the vehicle.

  The power supply unit 18 is energized from the battery 36 when the ignition switch (IGN) 35 is turned on, and supplies a necessary power supply voltage to each unit of the digital tachograph 10. Further, the power supply unit 18 detects the battery voltage of the battery 36. The operation unit 22 is provided with various buttons that can be operated by the crew. An RTC (Real Time Clock) 23 includes a clock IC and measures the current time.

  2A and 2B are views showing the appearance of the digital tachograph 10 and the arrangement of each device mounted on the vehicle 30. FIG. As shown in FIG. 2A, on the front surface of the digital tachograph 10, an LCD 14, a printer 16, a recording medium connector 17 to which a recording medium 31 is connected, and an operation unit 22 including various operation buttons are provided. . FIG. 2B shows the positional relationship among the digital tachograph 10, the vehicle speed sensor 32, the engine speed sensor 33, the battery 36 and the GPS receiver 37 mounted on the vehicle 30.

  3A to 3D are diagrams showing a recording medium 31 connected to the digital tachograph 10 and a data processing device 50 from which operation data is read out from the recording medium 31. FIG. In the present embodiment, the USB memory described above is used as the recording medium 31, but an IC memory card or the like may be used. The recording medium 31 includes an identification information storage unit 311 in which identification information such as driver information, administrator information, and backup information is stored, and a data storage unit 312 in which operation data is written. The driver information includes information indicating that the driver is a driver and information (ID) for identifying the driver name (A, B, C). The manager information includes information indicating that the manager is limited to one person or a specific plurality of persons.

  In the present embodiment, the recording medium 31 includes a driver recording medium 31a in which driver information is stored, an administrator recording medium 31b in which administrator information is stored, and a backup recording medium in which backup information is stored. There are three types of 31c. When it is not necessary to distinguish these recording media, the recording media 31 are collectively referred to. FIGS. 3A, 3B, and 3C show a driver recording medium 31a, an administrator recording medium 31b, and a backup recording medium 31c, respectively. Here, although these recording media are the same media, they may be different media so that they can be easily distinguished. For example, the driver recording medium 31a may be an IC card memory, the administrator recording medium 31b may be a USB memory, and the backup recording medium 31c may be a hard disk drive. In this case, however, it is necessary to prepare a plurality of types of recording medium connectors corresponding to each medium.

  A data processing device 50 shown in FIG. 3D is configured by a general-purpose computer system including a computer main body 51, a display 52, a keyboard 54, a mouse 55, and the like. A connection connector 57 to which the above-described recording media 31 for the driver, the manager, and the backup are connected is provided at the lower front portion of the computer main body 51. The data processing device 50 reads the operation data recorded on the recording medium 31, analyzes the operation data read by the analysis software installed in the computer main body 51, and performs various data processing.

  FIG. 4 is a diagram showing the contents of operation data recorded in the data recording unit 13 in the order of operation. In FIG. 4, operation data is recorded in the order of operation, that is, in the order of “operation 1”, “operation 2”, and “operation 3”. In the recording medium 31, as operation data, data such as an engine speed, a traveling speed, a traveling distance, an operation time, a position coordinate, a battery voltage, and the like that change every time according to the traveling for each identification number (ID) of the driver. Is recorded.

  The operation of the digital tachograph 10 having the above configuration will be described. FIG. 5 is a flowchart showing a procedure for recording operation data and writing to the recording medium 31. This processing program is stored in the ROM in the CPU 11 and is executed by the CPU 11. Note that the CPU 11 in the digital tachograph 10 is energized even when the ignition switch (IGN) 35 is turned off.

  The CPU 11 waits until the ignition switch (IGN) 35 is turned on (step S1). When the IGN 35 is turned on, the CPU 11 waits until the driver recording medium 31a is inserted and connected to the recording medium connector 17 (step S2). . In step S2, the process of detecting that the driver recording medium 31a is inserted and connected to the recording medium connector 17 corresponds to a connection detecting means.

  When the driver recording medium 31a is connected, the CPU 11 determines whether or not the driver information is stored in the driver recording medium 31a, and authenticates the driver information (step S3). Note that the process of step S3 may be performed automatically or may be performed when the driver presses an authentication button provided on the operation unit 22 of the digital tachograph 10. Further, when authenticating the driver information, it may be simply checked whether or not the driver information is stored in the driver recording medium 31a, or the driver information stored in the driver recording medium 31a. Is matched with the driver information set in the table memory 13c of the data recording unit 13, and if it matches, the driver information may be stored as authentication OK.

  When it is determined in step S3 that the driver information is not stored, the CPU 11 generates an error (step S15) and ends the process. On the other hand, when it is determined in step S3 that the driver information is stored, the CPU 11 registers the driver information in the data memory (SRAM) 13a in the data recording unit 13 (this time is set as timing a). At the same time, the connection of the driver recording medium 31a is released so that the driver recording medium 31a can be taken out (step S4). Thereby, the crew member can take out the driver's recording medium 31a. At this time, the digital tachograph 10 may display on the LCD 14 that the driver information is registered and that the driver recording medium 31a can be taken out.

  Thereafter, the CPU 11 detects the vehicle speed pulse signal detected by the vehicle speed sensor 32, the engine rotation pulse signal detected by the engine speed sensor 33, the position information received by the GPS receiver 37, the current time measured by the RTC 23, and the like. It starts recording operation data such as traveling speed and engine speed obtained based on the data in the data memory (SRAM) 13a in the data recording unit 13 (step S5).

  The CPU 11 determines whether or not the data capacity (work area buffer) of the data memory (SRAM) 13a in the data recording unit 13 is full (step S6). If it is not full, the CPU 11 returns to the process of step S5. On the other hand, when it becomes full, CPU11 moves the operation data memorize | stored in the data memory 13a in the data recording part 13 to the backup memory (FROM) 13b (step S7).

  And CPU11 discriminate | determines whether it is stopping (stop) based on the vehicle speed pulse signal obtained from the vehicle speed sensor 32 (step S8), and when not stopping, it returns to the process of step S5. Here, when the vehicle is stopped, the operation data recording is stopped due to the vehicle being stopped.

  On the other hand, when the vehicle is stopped (this time is set as timing b), the CPU 11 determines whether or not the driver recording medium 31a inserted in step S3 is inserted again and connected to the digital tachograph 10. (Step S9). When the driver recording medium 31a is inserted, the CPU 11 operates immediately before, that is, from the time when the driver information is registered in step S3 (time point a) to the stop in step S4 (time point b). Data is discharged (written) to the driver recording medium 31a (step S10). Thereafter, the CPU 11 makes it possible to take out the driver recording medium 31a (step S15). When the driver recording medium 31a is taken out, the process returns to step S2.

  On the other hand, if the driver recording medium 31a is not inserted in step S9, the CPU 11 determines whether or not the administrator recording medium 31b is inserted and connected to the digital tachograph 10 (step S11). When the administrator recording medium 31b is inserted, the CPU 11 operates immediately before, that is, from the time when the driver information is registered in step S3 (timing a) to the stop in step S8 (timing b). Data is discharged to the administrator recording medium 31b (step S12). Thereafter, the CPU 11 enables the manager recording medium 31b to be taken out in step S15, and when the manager recording medium 31b is taken out, the process returns to step S2.

  On the other hand, if the administrator recording medium 31b is not inserted in step S11, the CPU 11 determines whether or not the backup recording medium 31c is inserted and connected to the digital tachograph 10 (step S13). When the backup recording medium 31c is inserted, the CPU 11 discharges all the operation data recorded in the backup memory 13b to the backup recording medium 31c (step S14). Thereafter, the CPU 11 enables the backup recording medium 31c to be taken out in step S15, and when the backup recording medium 31c is taken out, the process returns to step S2.

  If the backup recording medium 31c is not inserted in step S13, the CPU 11 returns to the process of step S5. Note that the ejection (writing) operation in steps S10, S12, and S14 may be performed automatically with the recording medium 31 inserted, or the writing provided on the operation unit 22 of the digital tachograph 10 by the driver. This may be done by pressing a button.

  FIG. 6A to FIG. 6C are diagrams specifically showing the operation data siphoning operation. In the figure, d1 to d46 indicate operation data. For example, the operation data d1 is operation data traveled by the driver A on the 2nd as a date. The same applies to the operation data d2 to d6. When it is necessary to particularly distinguish the driver as the driver recording medium 31a, for example, the driver recording medium 31a for the driver A is used as the recording medium 31aA for the driver A, and the driver recording medium for the driver B is used. The medium 31a is a driver B recording medium 31aB, and the driver C recording medium 31a is a driver C recording medium 31aC.

  6A, when the driver C recording medium 31aC is inserted on the 17th and authentication of the driver C is started, and the driver C is registered, the operation is started. When the creation of data is started and the recording medium 31aC for the driver C is inserted again on the 18th day of the next day, the operation data d5 and d6 of the previous day, that is, the 17th and 18th, are stored in the recording medium 31aC for the driver C. Sucked up. At this time, the past operation data d1 to d4 before the 17th are not sucked up in normal operation in order to shorten the sucking time.

  6B, in the vehicle 1, the driver A recording medium 31aA is inserted on the 17th day in the vehicle 1, the driver A authentication is started, and the driver A is registered. Then, the creation of the operation data is started, and when the administrator recording medium 31b is inserted on the 18th day of the next day, the operation data d15 and d16 of the driver A on the previous day, that is, the 17th and 18th days, The recording medium 31b is sucked up. At this time, the past operation data d11 to d14 before the 17th are not sucked up in normal operation in order to shorten the sucking time.

  In the vehicle 2, the recording medium 31aB for the driver B is inserted on the 11th, and the authentication of the driver B is started. When the driver B is registered, the creation of operation data is started, and the 11th of the same day is started. When the manager recording medium 31b is inserted into the manager recording medium 31b, only the operation data d24 of the driver B immediately before, that is, the 11th day, is sucked into the manager recording medium 31b. At this time, the past operation data d21 to d23 before 11th are not sucked up in normal operation in order to shorten the sucking time.

  Further, in the vehicle 3, when the driver C recording medium 31aC is inserted on the 14th and the authentication of the driver C is started and the driver C is registered, the creation of operation data is started, and the 15th day of the next day is started. When the administrator recording medium 31b is inserted, the operation data d35 and d36 of the driver C immediately before, that is, the 14th and 15th, are sucked into the administrator recording medium 31b. At this time, the past operation data d31 to d34 before the 14th are not sucked up in normal operation in order to shorten the sucking time.

  In the backup recording medium sucking operation shown in FIG. 6C, when the backup recording medium 31c is inserted on the 18th, all the operation data d41 to d46 are sucked to the backup recording medium 31c.

  FIGS. 7A and 7B are diagrams illustrating operation data siphoning operation when a predetermined operation data siphoning operation procedure is not observed. FIG. 7A shows an operation in which the previous driver sucks up the operation data after the next driver registers. Specifically, after the driver A recording medium 31aA is inserted and the driver A is registered at timing t1, the driver B recording medium 31aB is inserted and the driver B is registered at timing t2. Further, when the driver A has noticed that the operation data of the operation 1 has not yet been picked up at the timing t3 and the driver A recording medium 31aA is inserted after the registration of the driver B, the range of the operation data to be picked up is “operation 1 ”. Further, when the administrator recording medium 31b is inserted here, the range of the operation data to be sucked up is “operation 2”. Furthermore, after the operation data of the driver A is sucked up at the timing t3, if the recording medium 31aB for the driver B is inserted at the timing t4, the range of the operation data sucked up at this time is “operation 2 + operation 3”.

  The siphoning operation shown in FIG. 7A is realized by partially changing the procedure shown in the flowchart of FIG. FIG. 8 is a diagram showing a changed portion of the flowchart of FIG. In step S9, when the driver recording medium 31aA already inserted in step S3 is inserted again, the process of step S10 is performed as described above. On the other hand, if the driver recording medium 31aA already inserted in step S3 is not inserted again in step S9, the CPU 11 determines whether or not another driver recording medium 31aB is inserted (step S9A). ). When another driver recording medium 31aB is inserted, the CPU 11 returns to the process of step S3, registers that there is information of the driver B, and performs the processes after step S4. On the other hand, when another driver recording medium 31aB is not inserted in step S9A, the CPU 11 proceeds to the process of step S11 described above. Accordingly, the operation data siphoning operation when the predetermined operation data siphoning procedure shown in FIG. 7A is not observed is realized.

  FIG. 7B is a diagram showing the operation of copying operation data when the next driver does not register. Specifically, after the driver A recording medium 31aA is inserted at the timing t11 and the driver A is registered, the driver A is switched to the driver B at the timing t12, but the driver B recording medium 31aB is changed. Driver B is not registered because it was not inserted. Furthermore, when the driver A recording medium 31aA or the administrator recording medium 31b is inserted at the timing t13, the range of operation data to be sucked is “operation 1 + operation 2”. That is, the operation data of the “operation 2” of the driver B is collected as the operation data of the driver A. Note that when the recording medium 31aB for the driver B is inserted at the timing t13, the operation data is not downloaded, and the registration of the driver B is performed as in FIG.

  As described above, in the digital tachograph of the present embodiment, when the driver recording medium is inserted after the driver information is registered after the driver information is registered, the previous operation data can be sucked into the recording medium. Furthermore, when the administrator recording medium is inserted, the previous operation data can be sucked up even by a person other than the driver. Further, when the backup recording medium is inserted, all the operation data can be sucked up. As described above, since the operation data is read in the reading range corresponding to the identification information stored in the recording medium, the operation data can be taken out as necessary, and the operation data recorded in the digital tachograph is prevented from being left behind. can do. In addition, it is possible to diversify how to read operation data.

  Further, since the operation data from the registration of the driver information to the end of the operation by the driver information is recorded, the operation data can be recorded for each driver. In addition, it becomes easy to manage the operation data from the registration of the driver information to the end of the operation.

  Further, since the identification information recorded on the recording medium is read, the identification information can be easily recognized. Moreover, since only the last operation data is written in the recording medium, the operation data read time can be shortened.

  Further, when the identification information is driver information, reading of operation data by a person other than the driver set in advance can be prevented, and security is improved. In addition, when the identification information is manager information, since the previous operation data is written to the recording medium, the operation data can be read out by the administrator without being driven by the driver, and the operation data can be prevented from being left behind. it can.

  Further, when the identification information is backup information, since all the operation data is written in the recording medium, it is possible to reliably prevent the operation data from being left behind.

  The present invention is not limited to the configuration of the above-described embodiment, and any configuration can be used as long as the functions shown in the claims or the functions of the configuration of the present embodiment can be achieved. Is also applicable.

  For example, in the above embodiment, the recording medium identification information is driver information, administrator information, and backup information, but it may be divided into three or more, for example, group information, confidential information, and the like. The reading range may be set according to each.

  In the above-described embodiment, the digital tachograph recognizes the identification information by reading the identification information stored in the recording medium. However, as a connection connector to which the recording medium is connected, it corresponds to a recording medium of a different type. When a plurality of connection connectors (a plurality of connection portions) are provided, the recording medium corresponding to each connection connector may be connected so that the identification information of the recording medium can be recognized. As a result, the identification information can be recognized from the type of the recording medium.

  In the above embodiment, the recording medium that can be connected to the digital tachograph is connected to the digital tachograph by being inserted into the connection connector, but is connected to the digital tachograph by a wireless signal or an infrared signal without being inserted into the connection connector. You may do it.

  Moreover, although the case where it applied to the digital tachograph mounted in the vehicle was shown in the said embodiment, the operation recording apparatus of this invention may be applied not only to a vehicle but to various vehicles. In addition, the operation data is not limited to those listed in the above embodiment, and may be data indicating various operation states.
