  As described above, according to the first aspect of the present invention, when the approach determining means determines that the vehicle is within the first range, the control means approaches the terminal (display unit) to the work point. When the stop determination means determines that the vehicle is within the second range, the work content is displayed on the terminal. When the operator inputs that the work content displayed on the terminal is complete by operating the operation unit, the recording means records the displayed work content as operation data in the operation data recording medium. By doing in this way, first, by determining that it is in the first range, it is possible to reduce the loss of travel time and eliminate leakage such as collection and delivery. Moreover, it can detect reliably that it has stopped in the work position by determining that it has stopped in the 2nd range. Then, since the work content is recorded as operation data only by the operator performing the operation completion operation, the work content input work can be reduced and input mistakes can be reduced.

  According to the second aspect of the present invention, the stop determination means determines that the vehicle has stopped when the vehicle has stopped for a predetermined time or more. Therefore, it is possible to prevent erroneous detection due to a temporary stop such as waiting for a signal. The work contents can be displayed at the work place.

The memory card I / F 25 also includes a memory card slot that allows the memory card M to be freely attached and detached. The audio I / F 26 is an I / F that is connected to a speaker or the like in order to output a sound such as a warning sound from the digital tachogoraf 10.

  The RTC 27 is a clock (Real Time Clock) that is a time at which the digital tachograph 10 records a running situation, work contents, and the like. The EEPROM 28 stores rewritable information among programs and setting data that operate on the CPU 11.

  The H / TI / F 29 is an I / F for communicating with a handy keypad 40 to be described later. For example, a USB (Universal Serial Bus) I / F is used, but it may be an I / F by wireless communication. The SW input 30 indicates input signals of various operation switches provided on the case outer surface of the digital tachograph 10. The LCD controller 31 is a circuit for controlling an LCD (Liquid Crystal Display) that functions as a display means provided on the outer surface of the case of the digital tachograph 10, and displays on the LCD in accordance with characters or image information output from the CPU 11. To control.

  The digital tachograph 10 having the above-described configuration obtains a traveling state such as a vehicle speed, a traveling time, a traveling distance, an engine rotational time, and an engine rotational speed from the speed / engine rotational I / F 12 and other I / Fs. Until the warehousing, the CPU 11 records these traveling conditions as operation data on a memory card M as an operation data recording medium sequentially via the memory card I / F 25. That is, the CPU 11 functions as a recording unit.

  As shown in FIG. 2, the handy key 40 includes a CPU 41, an I / F 42, a display unit 43, a FROM 44, a communication I / F 45, and a keyboard 46. The handy key 40 is detachably configured as a terminal of the digital tachograph 10 and is connected by wire or wirelessly. FIG. 1 shows an example of connection by wire (USB).

  The CPU 41 is a central processing unit that performs various processes and controls according to a predetermined program. The CPU 41 stores a ROM that is a read-only memory storing a program for the CPU 41, various data, and the CPU 41. A RAM, which is a readable / writable memory having an area necessary for processing work, is incorporated. The CPU 41 operates by reading out programs, data, and the like stored in the ROM and RAM.

  The I / F 42 is an I / F that connects the display unit 43 and the CPU 41, which will be described later, and also functions as a driver that drives the display unit 43 in accordance with characters or image information displayed on the display unit 43 output from the CPU 41. To do.

  The display unit 43 is configured by, for example, an LCD (liquid crystal display), and displays characters, image information, and the like that are driven from the I / F 42 and output from the CPU 41.

  The FROM 44 is a nonvolatile memory in which various data used by the CPU 41 is recorded.

  The communication I / F 45 is an I / F for the CPU 41 to communicate with the digital tachograph 10, and performs data transmission / reception with the digital tachograph 10 by wired communication using, for example, a USB (Universal Serial Bus) or the like.

  The keyboard 46 as an operation unit includes a plurality of function keys 46f and numeric keys 46t as shown in FIG. For the function key 46f, for example, one operation key is assigned to each work category such as loading, unloading, waiting, inspection, and rest.

  The handy numeric keypad 40 configured as described above records collection / delivery data such as work contents performed by a crew member (worker) or the like in advance in the memory card M of the digital tachograph 10 at an office or the like, and from the memory card M during subsequent delivery processing. It is downloaded to the FROM 44 of the handy keypad 40. That is, the FROM 44 functions as a work recording unit in which work points where work needs to be performed and work contents performed at the work points are recorded in advance.

  Next, operations of the digital tachograph 10 and the handy ten key 40 configured as described above will be described with reference to the flowchart of FIG. In the flowchart of FIG. 3, the operation on the handy key 40 side is executed by the CPU 41, and the operation on the digital tachograph 10 side is executed by the CPU 11.

  First, in step S11 on the digital tachograph 10 side, it is determined whether or not there is latitude / longitude information. If yes (if Y), the process proceeds to step S12. If not (N), the process waits in this step. . Since the latitude / longitude information is acquired via the GPS I / F 19, it is determined in this step whether the latitude / longitude information calculated by the GPS receiver is input from the GPS I / F 19.

  Next, in step S12, the latitude / longitude information determined to be present in step S11 is transmitted to the handy ten key 40 via the H / TI / F 29, and the process proceeds to step S13.

  On the other hand, in step S21 on the handy ten key 40 side, it is determined whether or not there is collection / delivery data. If there is (Y), the process proceeds to step S22. If not (N), the process waits in this step. In this step, as described above, the collection / delivery data is stored in the memory card M at the office as pre-processing, and during the delivery process performed after the memory card M is mounted on the digital tachograph 10, the digital tachograph 10 stores the FROM 44 of the handy ten key 40. The collection / delivery data has been downloaded, and the presence / absence of the downloaded collection / delivery data is determined.

  This collection / delivery data includes, for example, the work place name, product name, and quantity, latitude / longitude information of the work place, and an approach capturing radius for notifying the approach to the work place described later (a predetermined distance from the work place as a radius). And a work place capturing radius for notifying the work place. That is, the approach capture radius is the first range and the work place capture radius is the second range. The work place capture radius is a radius value smaller than the approach capture radius. However, the work place capture radius may not necessarily be set in the range, and may be the latitude / longitude information of the work place itself (radius 0). Further, the approach capture radius and the work place capture radius may not be common to all work places, and may be set for each work place or may be set for each of a plurality of work places.

  Next, in step S22, the latitude / longitude information transmitted by the digital tachograph 10 in step S12 is received, and whether the received latitude / longitude information is within the range indicated by the approaching capture radius set in the collection / delivery data. If it is within the range indicated by the approaching capture radius (in the case of Y), the process proceeds to step S23, and if not within the range indicated by the approaching capture radius (in the case of N), the process returns to step S21. That is, the CPU 41 functions as an approach determination unit that determines whether the vehicle is within the first range centered on the work point based on the position of the vehicle.

  Next, in step S23, since it was determined in step S22 that it is within the range indicated by the approach capturing radius, the display unit 43 is displayed indicating the approach to the work place, and the process proceeds to step S24.

  Next, in step S24, it is determined whether or not the vehicle has stopped. If the vehicle has stopped (Y), the process proceeds to step S25. If not (N), the process returns to step S22. In this step, the vehicle speed information input from the speed / engine rotation I / F 12 is acquired via the CPU 11 and the H / TI / F 29 to determine whether or not the vehicle is stopped and the stop position. It is also determined whether or not is within the work place capture radius and whether or not the stop time is longer than a predetermined time. That is, the CPU 41 functions as a stop determination unit that determines whether or not the vehicle has stopped for a predetermined time or more in a second range that is closer to the work point than the first range.

  That is, in step S24, it is determined as affirmative (Y) that the vehicle has stopped for a predetermined time or longer within the work place capturing radius. The predetermined time for determining the stop is a length of time that is not determined to be a temporary stop, such as waiting for a signal, and the predetermined speed is set in advance, for example, less than 2 km / h, but the speed is determined appropriately. May be.

  Next, in step S25, the work instruction set in the collection and delivery data corresponding to the work place is displayed on the display unit 43, and the process proceeds to step S26. That is, the CPU 41 functions as a control means by this step and the above-described step S23.

  Next, in step S26, after completion of the work instructed by the crew member, it is determined whether or not a predetermined designation key in the keyboard 46 has been operated. If operated, the process proceeds to step S27. Return to S25.

  Next, in step S27, the collection / delivery data instructed in step S25 is transferred to the digital tachograph 10.

  On the digital tachograph 10 side, it is determined whether or not collection / delivery data has been transmitted from the handy ten key 40 in step S13. If there is, the process proceeds to step S14, and if not, the process returns to step S11.

  Next, in step S14, the collection / delivery data is stored in the memory card M as work information (operation data). In other words, since the operator has input from the operation unit that the work content displayed on the display unit has been completed, the CPU 11 serving as a recording means uses the displayed work content as operation data on the operation data recording medium. It is recorded on a certain memory card M.

  Here, a specific example of the above-described operation will be described with reference to FIGS. FIG. 4 is a diagram showing the relationship between the work place and the capture radius, and FIG. 5 is a diagram showing the relationship between the capture radius and the display content. As shown in FIG. 4, the approach capture radius in the range having x1 (for example, 100 m) as the radius value centered on the work location and the work location in the range having x2 (for example, 10 m) as the radius value from the work location as the center. The capture radius is set. Point a is within the approach capture radius and outside the work location capture radius, and point b is the work location.

  When the vehicle reaches a point a that is within the approaching capture radius, the above-described steps S11, S12, S22, and S23 are executed, and as shown in FIG. Is displayed. Then, when the vehicle reaches point b, which is a work place, steps S11, S12, S22, S23, S24, and S25 are executed, and the message “Loading. Place name: Nagoya Nishi, customer: Work content such as “XX Trading, Product Name: Drinking Water” is displayed. When the crew member completes the work displayed at the work position and operates the designation key of the handy ten key 40 to input the work completion, steps S26, S27, S13, and S14 are executed, and the work contents are those of the digital tachograph 10. It is recorded as work information in the memory card M.

  In addition, the display when reaching point a (display indicating that the work place is approached) is not limited to displaying the work content as shown in FIG. 5 (for example, “approaching the loading place”). You may make it display the place name, the customer, etc. of a place (for example, "I am approaching XX trading in Nagoya west").

  According to the above embodiment, when the CPU 41 of the handy numeric keypad 40 determines that the vehicle is within the approach capturing radius, the display unit 43 displays that the work point is approaching, and the vehicle captures the work location. When it is determined that the work content is within the radius, the work content is displayed on the display unit 43, and when the crew member inputs the work content displayed by operating the designation key, the CPU 11 of the digital tachograph 10 Since the work contents at the work point are recorded in the memory card M as operation data, it is possible to reduce the loss of travel time and eliminate leakage such as collection and delivery by first determining that it is within the approach and capture radius. In addition, it is possible to reliably detect the stop at the work position by determining that the stop is within the work place capturing radius. And, since the work contents are recorded as operation data simply by the crew member performing the work completion operation, input work of work contents can be reduced and input mistakes can be reduced.

  Further, since the CPU 41 determines that the vehicle is stopped when the vehicle has stopped for a predetermined period of time or longer, it prevents erroneous detection due to a temporary stop such as waiting for a signal and reliably displays the work contents at the work place. Can do.

  In the embodiment described above, the collection / delivery data is stored in the memory card M at the office and downloaded to the handy numeric keypad 40 at the time of the delivery process, but wirelessly communicates with the office via the communication terminal I / F 21 of the digital tachograph 10. Communication may be performed to acquire collection / delivery data and download it to the handy keypad 40. By doing in this way, even if there is a change or addition of work after leaving, it can be downloaded by communication to reflect the change or addition of work. In this case, the communication terminal I / F 21 (digital tachograph 10) functions as a receiving unit, and the CPU 41 functions as a changing unit.

  Further, the data that is changed by downloading through the communication described above is not limited to the work content such as the work place and the product name, but the approach catching radius and the work place catching radius may be changed. Further, the approach capturing radius and the work place capturing radius may be changed by the crew with the handy key 40.

  In addition, embodiment mentioned above only showed the typical form of this invention, and this invention is not limited to embodiment. That is, various modifications can be made without departing from the scope of the present invention.
