  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an example of an overall configuration diagram of the travel information collection system 100.

  The travel information collection system 100 includes a plurality of operation data transmission devices (hereinafter referred to as “on-vehicle devices”) 1 mounted on each of the vehicles C1 to n vehicles Cn, and a server device 50. Furthermore, the terminal device 20, the terminal device 30, a GPS (Global Positioning System) satellite 40, and the Internet network 60 are used in the travel information collection system 100. In the following description, in order to make the description easy to understand, the vehicle C1 is mainly described as a representative. Since the terminal device 20 and the terminal device 30 have the same configuration, the terminal device 20 will mainly be described as a representative. The number of terminal devices is also an example, and at least one terminal device may be connected to the server device 50 via the Internet network 60.

  In the present embodiment, the in-vehicle device 1 mounted on the vehicle C1 and the server device 50 are connected by a wireless packet communication network (wireless transmission path) as an example. Thereby, wireless data communication can be performed between the in-vehicle device 1 and the server device 50. In this embodiment, the packet communication network is used for the wireless transmission path, but a wireless transmission path other than the packet communication network (for example, a wireless transmission path using a mobile phone) may be used.

  Here, in the traveling information collection system 100, when an administrator (for example, a transporter) of the vehicle (for example, a truck) C1 makes a use contract with an operator that provides the system 100, the operator In 50, identification data for identifying the vehicle C1 is registered. Thereby, the server apparatus 50 manages the operation data transmitted from the in-vehicle apparatus 1 based on the identification data for each vehicle to be managed by the usage contract (details will be described later). When the in-vehicle device 1 transmits the operation data of the vehicle C1 to the server device 50 side, the in-vehicle device 1 transmits the identification data of the vehicle C1 itself at the same time. The vehicle to be managed by the travel information collection system 100 is not limited to a truck, for example, and may be a general passenger car or the like.

  In addition, the server device 50, the terminal device 20, and the terminal device 30 are connected via the Internet network 60, and the server device 50 transmits vehicle travel information to the terminal device 20 and the terminal device 30 via the Internet network 60. . Thereby, the user can obtain travel information of a plurality of vehicles from the terminal device 20 and the terminal device 30. A specific example of the travel information will be described later. Hereinafter, the configuration of the in-vehicle device 1, the server device 50, and the terminal device 20 will be specifically described.

<In-vehicle device>
FIG. 2 is a block diagram illustrating an example of the in-vehicle device 1. As shown in FIG. 2, the in-vehicle device 1 includes a GPS receiver 11, a vehicle speed sensor 12, a control unit 13, a transmission buffer 14, a communication device 15, and a battery power source 16.

  The GPS receiver 11 receives radio waves from the GPS satellite 40 by a GPS antenna (not shown), and acquires position data (longitude, latitude) while the vehicle is traveling in time series.

  The vehicle speed sensor 12 measures the vehicle speed of the vehicle. For example, the vehicle speed sensor 12 measures a vehicle speed (vehicle traveling speed: vehicle speed data) based on a vehicle speed pulse signal obtained by rotating the wheel.

  The control unit 13 is a processor that performs overall control of the in-vehicle device 1. The control unit 13 controls each unit of the in-vehicle device 1 by executing a program stored in advance in the control unit 13. The control unit 13 includes a RAM (Random Access Memory) for use in arithmetic processing and the like.

  The control unit 13 also functions as a continuous travel time measurement unit 13a and a stop time measurement unit 13b. The control unit 13 has a timer for measuring time. When the continuous travel time measurement unit 13a detects that the vehicle C1 is in a travel state based on the measurement of the vehicle speed sensor 12, the continuous travel time measurement unit 13a measures the continuous travel time by integrating the time from the start of travel of the vehicle C1. Moreover, the stop time measurement part 13b will stop by integrating | accumulating the time from the driving | running | working stop of the vehicle C1, if it detects based on the measurement of the vehicle speed sensor 12 that the vehicle C1 will be in a stop state (vehicle speed is 0 km / h). Measure time.

  The control unit 13 has a first counter that counts continuous running time and a second counter that counts stop time in the RAM inside the control unit 13. Thereby, the continuous running time measurement unit 13a measures the continuous running time by incrementing the first counter every minute. In addition, the stop time measuring unit 13b measures the stop time by incrementing the second counter every minute.

  In the present embodiment, when the vehicle is continuously stopped for 10 minutes or more, the control unit 13 estimates that the driver is resting. Therefore, in this embodiment, if the time that the vehicle is stopped is continuously less than 10 minutes, the control unit 13 counts as continuous running time. This is to prevent the control unit 13 from estimating that the vehicle is taking a break when the vehicle is temporarily stopped, for example, waiting for a signal. In addition, when the driver starts driving the vehicle again after a break of, for example, 10 minutes or more, the continuous driving time is reset again and counted.

  The transmission buffer 14 is a buffer memory that temporarily records position data, vehicle speed, continuous travel time, and stop time as operation data.

  The communication device 15 reads the operation data from the transmission buffer 14 and transmits it to the server device 50 by wireless data communication.

The battery power source 16 is a power source that supplies electric power to the in-vehicle device 1 during operation of the idling stop mechanism. In recent years, large vehicles such as trucks include models equipped with an idling stop mechanism that detects a stop and stops the engine, detects a start operation, and restarts the engine. When the idling stop mechanism is mounted on the vehicle C1, when the idling stop mechanism is operated, the control unit 13 switches to supplying power from the battery power supply 16 so that the power source of the in-vehicle device 1 is not turned off. . Thereby, for example, even when the idling stop mechanism is operated by waiting for a signal or the like, the in-vehicle device 1 can continue to operate.
<Server device>
Next, the server device 50 will be described. FIG. 3 is a block diagram illustrating an example of the server device 50. As illustrated in FIG. 3, the server device 50 includes a server reception unit 51, a CPU (Central Processing Unit) 52, a database 53, a server transmission unit 54, and a data bus 55. The server reception unit 51, the CPU 52, the database 53, and the server transmission unit 54 are connected to each other via a data bus 55.

  The server receiving unit 51 receives operation data transmitted from the plurality of in-vehicle devices 1 by wireless data communication. The server reception unit 51 has a buffer memory (not shown) that temporarily records operation data. In addition, the server reception unit 51 receives command inputs and the like from the terminal device 20 and the terminal device 30 illustrated in FIG.

  The CPU 52 controls the operation of the server device 50 in an integrated manner. The CPU 52 also functions as a data distribution unit 52a, a reception unit 52b, a first average value calculation unit 52c, a second average value calculation unit 52d, and a determination unit 52e.

  The data distribution unit 52a distributes the operation data for each vehicle based on the identification data of each vehicle, and stores the operation data for each position data in time series in the management table 53a of the database 53.

  The accepting unit 52b accepts command input and the like from the terminal device 20 and the terminal device 30 illustrated in FIG. Here, the user can select, from the terminal device 20 and the terminal device 30, for example, a traveling route within a certain range among the traveling routes (roads) based on the position data. The accepting unit 52b accepts position data of a travel route (road) on a map which is a target selected by user input. Note that the selected target may be one point (latitude, longitude) on the travel path.

  The 1st average value calculation part 52c calculates the average value (average continuous travel time) of the newest continuous travel time of the several vehicle which passed the selected object based on the operation data for every vehicle. For example, when the vehicle C1 travels continuously for 60 minutes, stops for 15 minutes, and further travels continuously for 90 minutes, the latest continuous travel time for the vehicle C1 is 90 minutes. Therefore, the control unit 13 of the in-vehicle device 1 measures the stop time in addition to the continuous travel time.

  In the present embodiment, for example, the first average value calculation unit 52c first calculates the average value of the continuous travel time for each vehicle that has passed through the selected target. Next, the 1st average value calculation part 52c calculates the whole average value about the vehicle which passed the selected object further with respect to the average value of the continuous running time calculated about each vehicle. This overall average value is defined as the average continuous running time. This average continuous travel time corresponds to an example of travel information.

  The 2nd average value calculation part 52d calculates the average value of the vehicle speed data of the some vehicle which passed the selected object based on the operation data for every vehicle. In the present embodiment, for example, the second average value calculation unit 52d first calculates the average value of the vehicle speed data for each vehicle that has passed through the selected target. Next, the 2nd average value calculation part 52d calculates the whole average value about the vehicle which passed the selected object further with respect to the average value of the vehicle speed data calculated about each vehicle. This overall average value is defined as average vehicle speed data. This average vehicle speed data corresponds to an example of travel information.

  The determination unit 52e determines whether or not the vehicle is stopped based on the operation data. When the vehicle is stopped for 10 minutes or more, the determination unit 52e determines that the vehicle is stopped (the driver is taking a break).

  The database 53 is a rewritable recording medium. Also, the management table 53a shown in FIG. 3 manages information used in the travel information collection system. Specifically, the management table 53a manages position information (latitude, lightness), continuous travel time (including stop time), vehicle speed, and the like as operation data in time series for each vehicle. For example, vehicle number 1 (identification data) is given to vehicle C1. Details of the management table 53a will be described later.

The server transmission unit 54 transmits travel information (average continuous travel time and average vehicle speed data) to the terminal device 20 or the terminal device 30 that has received a command input via the Internet network 60. In addition, the server transmission unit 54 transmits travel information (position data of a place where the vehicle is stopped) to the terminal device 20 or the terminal device 30.
<Terminal device>
FIG. 4 is a block diagram illustrating an example of the terminal device 20. The terminal device 20 is a personal computer, for example. As shown in FIG. 4, the terminal device 20 includes a communication interface unit (hereinafter referred to as “communication I / F unit”) 21, a keyboard 22, a mouse 23, a display monitor 24, a CPU 25, and a storage unit 26. Prepare.

  The communication I / F unit 21 provides a communication interface for communicating with the server device 50 via the Internet network 60. The keyboard 22 receives an instruction input from the user. The mouse 23 provides, for example, a user interface for the user to select and input a vehicle travel path on a map. The display monitor 24 displays, for example, a map based on the map data 26a and the output result of this embodiment on the screen.

  The CPU 25 is a processor that performs overall control of the terminal device 20. The CPU 25 also functions as a selection input receiving unit 25a, a communication unit 25b, and a display control unit 25c. The selection input receiving unit 25a receives, for example, a selection input of a travel path of the vehicle on the map via the mouse 23.

  For example, the communication unit 25 b transmits the position data of the selection input of the travel path of the vehicle to the server device 50 via the communication I / F unit 21. Further, the communication unit 25b receives, for example, the average continuous running time and the average vehicle speed data from the server device 50 via the communication I / F unit 21.

  For example, the display control unit 25c causes the display monitor 24 to display a diagram representing the average continuous running time and the average vehicle speed data. The storage unit 26 is a memory, and as an example, map data 26a such as a map of Japan is stored as electronic data.

  Next, the operation of the travel information collection system 100 will be described. In order to make the explanation easy to understand, here, first, the operation on the in-vehicle device 1 side and the operation on the server device 50 side will be described separately.

  FIG. 5 is a flowchart illustrating an example of the operation of the in-vehicle device 1 in the travel information collection system 100. FIG. 6 is a flowchart showing a subroutine of the scheduled task in step S102 of FIG. Here, when the control unit 13 accepts the start of the engine of the vehicle C <b> 1 by the driver's key operation, the process of the flowchart shown in FIG. 5 is started by the control of the control unit 13.

  Step S101: The control unit 13 initializes the in-vehicle device 1. Specifically, the control unit 13 activates the GPS receiver 11 and the vehicle speed sensor 12 of the in-vehicle device 1.

  Step S102: The control unit 13 executes a scheduled task subroutine which will be described later. The control unit 13 activates this scheduled task subroutine every minute.

  Step S103: The control unit 13 monitors whether or not the scheduled task is terminated due to the power-off input of the in-vehicle device 1, and when there is no power-off input (step S103: No), the control unit 13 performs step S102. Return to the process. On the other hand, when there is an input of power off (step S103: Yes), the control unit 13 ends the process of the flowchart shown in FIG.

  Next, the routine task subroutine (FIG. 6) will be described.

  Step S201: The control unit 13 determines whether the vehicle speed is 0 km / h based on the measurement result of the vehicle speed sensor 12. When the vehicle speed is not 0 km / h (step S201: No), the control unit 13 proceeds to step S202. On the other hand, when the vehicle speed is 0 km / h (step S201: Yes), the control unit 13 proceeds to step S203.

  Step S202: The stop time measuring unit 13b of the control unit 13 sets the stop time to zero. That is, the control unit 13 sets the value of the second counter to zero. When the value of the second counter is already zero, the control unit 13 skips the process of step S202.

  Step S203: The stop time measuring unit 13b increments the value of the second counter by 1. This incrementing value of 1 corresponds to 1 minute.

  Step S204: The control unit 13 determines whether or not the stop time is 10 minutes or longer. That is, the control unit 13 refers to the value of the second counter and determines whether or not the counter value is 10 or more. If the counter value is 10 or more (step S204: Yes), the control unit 13 proceeds to step S205. On the other hand, if the counter value is less than 10 (step S204: No), the control unit 13 proceeds to step S206.

  Step S205: The continuous running time measuring unit 13a of the control unit 13 sets the continuous running time to zero. That is, the continuous running time measuring unit 13a sets the value of the first counter to zero. As a result, when the driver starts traveling the vehicle C1 again, the control unit 13 sets the position as the starting point of traveling.

  Step S206: The continuous running time measuring unit 13a increments the value of the first counter by 1. This incrementing value of 1 corresponds to 1 minute.

  Step S207: The controller 13 temporarily stores the position data, continuous travel time, stop time, and vehicle speed values acquired by the GPS receiver 11 during execution of the scheduled task subroutine as operation data in the transmission buffer 14. . For convenience of explanation, the vehicle speed is a value at the time when the GPS receiver 11 acquires the position data.

  Subsequently, the control unit 13 instructs the communication device 15 to transmit wireless data. The communication device 15 reads the operation data from the transmission buffer 14 and transmits it to the server device 50.

  And the control part 13 will return to step S103 shown in FIG. 5, if the process of the subroutine shown in FIG. 6 is complete | finished. Note that the processing of the subroutine shown in FIG. 6 is completed within one minute.

  FIG. 7 is a diagram schematically showing how operation data is transmitted in time series. In FIG. 7, as an example, the value of the continuous travel time when the vehicle C1 starts traveling and passes from the point a to the point e is depicted. Here, after the vehicle C1 starts traveling, the control unit 13 activates the scheduled task every minute. As a result, operation data for every minute is transmitted to the server device 50.

  Next, the operation on the server device 50 side will be described. FIG. 8 is a flowchart illustrating an example of the operation of the server device 50. This flowchart is started by the control of the CPU 52 when the CPU 52 of the server device 50 shown in FIG. In this flowchart, it is assumed that the CPU 52 is always in operation until it receives a power-off instruction input.

  Step S301: Upon receiving an instruction to turn on the power, the CPU 52 performs initialization for operating the travel information collection system of this embodiment. For example, the CPU 52 controls the server reception unit 51 so that operation data from each vehicle can be received.

  Step S302: The CPU 52 determines whether or not operation data transmitted from a plurality of vehicles has been received. Here, when the server reception part 51 receives operation data by wireless data communication, it determines with CPU52 having reception of operation data (step S302: Yes), and transfers to step S303. On the other hand, when the server receiving unit 51 has not received operation data through wireless data communication, the CPU 52 determines that no operation data has been received (step S302: No), and returns to step S302.

  Step S303: The data distribution unit 52a of the CPU 52 distributes the operation data for each vehicle based on the identification data of each vehicle, and stores the operation data by distributing the position data to the management table 53a of the database 53 in time series. Go. Then, the CPU 52 returns to the process of step S302.

  Next, the operation between the terminal device 20 and the server device 50 will be described. FIG. 9 is a sequence diagram illustrating an example of the operation of the travel information collection system 100. Here, as an example, a sequence between the terminal device 20 and the server device 50 will be described. Note that the sequence on the terminal device 20 side is started when the CPU 25 receives an instruction input of the travel information collection system from the user after the terminal device 20 is activated by power-on. Hereinafter, description will be made with reference to FIGS. 3, 4 and 9 as appropriate.

  Step S401: The CPU 25 of the terminal device 20 shown in FIG. 4 initializes the travel information collection system. Specifically, although not shown in the sequence of FIG. 9, the communication unit 25 b of the CPU 25 transmits a sequence start command request to the server device 50 side via the communication I / F unit 21. As a result, the sequence on the server device 50 side shown in FIG. 9 is started under the control of the CPU 52 shown in FIG.

  Step S402: The CPU 25 reads the map data 26a in the storage unit 26 shown in FIG. 4 and displays a map on the display monitor 24.

  Step S403: The selection input accepting unit 25a of the CPU 25 accepts a selection input of a travel route on the map via the mouse 23. The position data of the selected object is temporarily stored in the storage unit 26. For example, when the user selects two points on the map, the two points on the map are converted into latitude and longitude and become position data.

  Step S404: The communication unit 25b of the CPU 25 reads the selected target position data from the storage unit 26. And the communication part 25b transmits to the server apparatus 50 side via the communication I / F part 21. FIG.

  Step S501: The receiving unit 52b of the server device 50 receives position data as a selection input via the server receiving unit 51. The server device 50 searches the management table 53a based on the position data. And the server apparatus 50 extracts the operation data of the range of a corresponding point, for example.

  FIG. 10 is a diagram illustrating a management table in which operation data in a range of corresponding points is extracted. FIG. 10 shows operation data of the vehicle C1. That is, the vehicle C1 travels on a travel path in the range A (point a to point e) and travels in a range B (point f to point h). Actually, the server device 50 extracts the operation data for all the vehicles that have traveled on the travel path in the range A (point a to point e) and range B (point f to point h).

  Step S502: The first average value calculation unit 52c of the server device 50 first calculates an average value of continuous running times of the vehicle C1. The 2nd average value calculation part 52d of the server apparatus 50 calculates the average value of the vehicle speed data of the vehicle C1.

  FIG. 11 is a diagram illustrating calculation results of the first average value calculation unit 52c and the second average value calculation unit 52d. FIG. 11 shows the operation data of the vehicle C1. Actually, the first average value calculation unit 52c and the second average value calculation unit 52d calculate average continuous running time and average vehicle speed data in a predetermined range based on operation data of a plurality of vehicles.

  Step S503: The server transmission unit 54 of the server device 50 transmits the average continuous travel time and the average vehicle speed data to the terminal device 20 as travel information. Then, the sequence on the server device 50 side ends once.

  Step S <b> 405: The communication unit 25 a of the terminal device 20 receives the average continuous travel time and the average vehicle speed data via the communication I / F unit 21. These data are temporarily stored in the storage unit 26.

  Step S406: The display control unit 25c of the terminal device 20 causes the display monitor 24 to display a diagram representing the average continuous running time and the average vehicle speed data.

  FIG. 12 is a diagram illustrating an example of contents displayed on the display monitor 24. FIG. 12A shows the average continuous running time and average vehicle speed data of the range A and the range B for the vehicle C1 for convenience of explanation. Actually, as shown in FIGS. 12 (b) and 12 (c), for example, the average continuous running time and the average vehicle speed data consisting of operation data of 100 vehicles (C1 to C100) are displayed. Here, for convenience of explanation, it is assumed that 100 vehicles (C1 to C100) have traveled the route of the range A and the range B.

  Step S407: The CPU 25 of the terminal device 20 determines whether or not there is an end instruction input from the user. When there is no end instruction input from the user (step S407: No), the process returns to step S403. At this time, the communication unit 25 b of the CPU 25 transmits a sequence start command request to the server device 50 side via the communication I / F unit 21. Thereby, the sequence on the server device 50 side shown in FIG. 9 is started again by the control of the CPU 52.

  On the other hand, if there is an end instruction input from the user (step S407: Yes), the CPU 25 ends the sequence processing on the terminal device 20 side shown in FIG.

  Although not shown in the sequence on the terminal device 20 side shown in FIG. 9, in response to a command request from the user, the server transmission unit 54 transmits the position data where the vehicle C1 is stopped as travel information.

  FIG. 13 is a diagram in which points estimated to be resting are extracted from the management table 53a shown in FIG. As an example, in FIG. 13, the continuous running time is counted until 10 minutes elapses after the vehicle speed becomes 0 km / h at the point a. The determination unit 52e determines that the vehicle C1 is stopped at the point a when the continuous running time becomes zero.

  In addition, after the communication unit 25b of the CPU 25 on the terminal device 20 side receives the position data where the vehicle C1 is stopped, the display control unit 25c of the CPU 25 displays a mark (for example, a break point) on the map on the display monitor 24 (for example, , Flag icons) may be displayed.

  From the above, in this embodiment, for example, as shown in FIG. 12B, it can be seen that the average continuous running time in the range A is 100 minutes and the average continuous running time in the range B is 90 minutes. The average continuous running time can be used as a judgment material, for example, where a business operator or the like who wants to install a break place should install a break place for the purpose of attracting customers. The reason is as follows.

  Conventionally, it has been required by law to take a 30-minute break for every four hours of driving, but this 30-minute break does not necessarily need to be taken all at once. It is also possible to obtain. In this case, it is considered that it is rare for the driver to take a break after a continuous running time of about 10 minutes from the start of driving. On the other hand, if the average continuous running time is about 100 minutes, it is considered that the possibility that the driver will stop when the break place is seen during driving is high. Therefore, as an example, if there is no resting place along the road at the point where the range A switches to the range B, the business operator or the like can consider that point as a resting place candidate. Further, when the CPU 25 of the terminal device 20 displays a mark indicating a resting point on the map on the display monitor 24, the business operator determines that the point is a place where it is easy to rest and excludes it from the examination target. be able to.

  Therefore, the travel information collection system of the present embodiment can collect travel information that serves as a guide indicating the installation location of the resting place. This makes it easier for the operator to grasp the point where the driver needs a rest area.

  Further, in the present embodiment, for example, as shown in FIG. 12C, it can be seen that the average vehicle speed data in the range A is 45 km / h and the average vehicle speed data in the range B is 60 km / h. These average vehicle speed data can be used as a judgment material, for example, where an administrative organization such as a police station can be expected to be more effective if a signboard for preventing overspeeding is installed. The reason is as follows.

  For example, when the legal speed in the range A and the range B is 50 km / h, it can be seen that in the range B, there are many drivers who are operating without complying with the legal speed. As an example, an administrative organization such as a police station can obtain a guideline that an overspeed prevention signboard or the like may be installed along the road where the range A switches to the range B.

  Therefore, the travel information collection system of the present embodiment can collect travel information that serves as a guide indicating the installation location of a traffic sign such as a sign for preventing overspeed. This makes it easier for an administrative body such as a police station to grasp a point where a sign for preventing overspeed, for example, should be installed.
