Description

  The present invention relates to an on-vehicle device, an operation management system, and a passage confirmation method for confirming passage when a vehicle stops at a predetermined point.

  Conventionally, in an operation management system that manages the operation state of a bus, when a vehicle-mounted device mounted on the bus receives a signal from a bus stop (bus stop), it notifies the management server accordingly. When receiving the notification, the management server recognizes that the notified bus is near the bus stop.

  As this type of prior art, an operation monitoring system that uses GPS to constantly grasp the position of the vehicle-mounted device is known (see Patent Document 1).

  Further, an operation management device is known in which the current time and the scheduled time of each bus stop are sequentially compared, and when the current time reaches the scheduled time, the operation status is “passed” (see Patent Document 2).

  CPU11 controls the onboard equipment 10 whole. The nonvolatile memory 12 stores an operation program executed by the CPU 11 and operation data described later. The volatile memory 13 is used as a working memory, and stores a passing event, a non-passing event, image data, and the like which will be described later.

  A memory card 34 possessed by a crew member is detachable from the card I / F 14. A speaker 53 is connected to the audio I / F 15. The RTC 16 (time acquisition unit) includes a clock IC and measures the current time.

  The SW input unit 17 receives ON / OFF of various switches. Various devices are connected to a CAN (Controller Area Network) I / F 18.

  A wide area communication terminal 31 and a narrow area communication terminal 32 are connected to the communication terminal I / F 19. The wide area communication terminal 31 (transmission unit) performs wide area communication with the radio base station 51 via the antenna 31 a and connects to the packet communication network 52. The narrow area communication terminal 32 performs narrow area communication with the narrow area communication path side wireless device 45 via the antenna 32a.

  The G sensor 21 detects gravitational acceleration. The camera I / F 22 is connected to a camera 55 that is mounted on the bus 5 and photographs the periphery of the bus 5 (for example, in front of the bus). A vehicle speed sensor 56 and an engine speed (NE) sensor 57 are connected to the vehicle speed / engine rotation I / F 23.

  The speed / engine rotation alarm unit 24 is an alarm device such as a lamp or a buzzer. Various external signals are input to the external input I / F 25. Various analog signals are input to the analog input I / F 26. Various signals are output to the external output I / F 27. An ETC vehicle-mounted device 59 is connected to the ETCI / F 28. A GPS receiver 58 is connected to the GPS I / F 29 (position acquisition unit).

  Moreover, the narrow area communication path side radio | wireless apparatus 45 is installed in the bus stop 40 as mentioned above, and performs the narrow area communication with the narrow area communication terminal 32 in the onboard equipment 10 via the antenna 42.

  FIG. 3 is a diagram showing a communication area 48 of the narrow area communication path side wireless device 45 installed at the bus stop 40. The narrow area communication path side wireless device 45 has an antenna 42 provided at a position 5 m from the ground, and projects a directional radio wave from the antenna 42 downward in the figure. When the bus 5 enters the communication area 48, the narrow area communication path side wireless device 45 performs narrow area communication with the vehicle-mounted device 10 mounted on the bus 5. In the present embodiment, a 5.8 GHz band DSRC (Dedicated Short Communication) system is employed. The communication area 48 is set so that communication is possible within a range of 3 m in width and 4 m in length at a height of 1 m from the ground.

  As described above, the server device 65 is installed in the application service provider (ASP) 60, receives data transmitted from the vehicle-mounted device 10 via the packet communication network 52, and receives the data from the computer device in the office 70. 75.

  Operation | movement of the bus operation management system 1 which has the said structure is shown. FIG. 4 is a flowchart showing an operation procedure of the vehicle-mounted device 10. This operation program is stored in the nonvolatile memory 12, and is executed by the CPU 11 every time the bus 5 passes through the bus stop.

  In addition, today's operation data is registered in the nonvolatile memory 12 in the vehicle-mounted device 10. FIG. 5 is a diagram showing the operation data table 36. The operation data can be registered, for example, by the crew member mounting the memory card 34 on the card I / F 14 and reading the contents recorded on the memory card 34. Moreover, the onboard equipment 10 may perform wide area communication with PC75 by the side of the office 70 via the wide area communication terminal 31, and may acquire and register operation data. In the operation data table 36, the name of the route operated by the bus 5, the position of the bus stop, and the estimated arrival time are recorded.

  The CPU 11 first acquires the current time from the RTC 16, and further acquires GPS position information with the GPS receiver 58 (step S1).

  The CPU 11 determines whether or not the current time is in time contention (passing time) that is a time zone including the estimated arrival time of the bus stop (step S2). The process of step S2 corresponds to a time determination unit.

  When it is in time contention, the CPU 11 determines whether or not the position of the bus 5 obtained from the GPS position information is in position contention near the bus stop (step S3). The process in step S3 corresponds to a position determination unit.

  When in the position contention, the CPU 11 enters the communication area 48 (narrow area) in which the bus 5 is capable of narrow-area communication until a wireless signal is received from the narrow-area communication path side wireless device 45 via the narrow area communication terminal 32. Wait until it enters (step S4). The process of step S4 corresponds to a narrow area determination unit. When the bus 5 enters the communication area 48 and narrow area communication is performed, the CPU 11 determines whether or not the speed of the bus 5 detected by the vehicle speed sensor 56 via the speed / engine rotation I / F 23 has become a value of 0 or less. That is, it is determined whether or not it has been stopped (step S5). The process in step S5 corresponds to a stop confirmation unit.

  When the speed of the bus 5 becomes 0 or less and the bus 5 is stopped, the CPU 11 records a passing event indicating that the bus is stopped at the volatile memory 13 (step S6). The process in step S6 corresponds to a recording unit. Note that the CPU 11 may record on the memory card 34 attached to the card I / F 14 instead of recording on the volatile memory 13. The same applies to the subsequent recording operation. Thereafter, the CPU 11 ends this operation.

  On the other hand, if the current time is not in the time contention in step S2, the CPU 11 determines whether or not the time content has been exceeded (step S7). If the time contention is not exceeded, the CPU 11 returns to the process of step S2.

  When the time contention is exceeded, the CPU 11 records the image captured by the camera 55 in the volatile memory 13 via the camera I / F 22 (step S8). Then, the CPU 11 records a non-passing event indicating that this bus stop has not passed in the volatile memory 13 (step S9). In step S <b> 9, the CPU 11 further transmits the image recorded in step S <b> 8 and non-passing event data to the PC 75 on the office 70 side via the wide area communication terminal 31. Thereafter, the CPU 11 ends this operation.

  On the other hand, if the GPS position information is not in the position contention in step S3, or if the speed of the bus 5 is not less than 0 and not stopped in step S5, the CPU 11 proceeds to the process in step S8.

  FIG. 6 is a flowchart showing an operation procedure of the PC 75 installed in the office 70. This operation program is stored in the ROM in the PC main body 71 and is executed by the CPU in the PC main body 71.

  The PC 75 waits until the image and the data of the non-passing event are received from the vehicle-mounted device 10 via the packet communication network 52 or the server device 65 in the ASP 60 (step S21). Upon receiving these data, the PC 75 displays a screen for notifying that the bus stop has not passed on the display 73 (step S22). Thereafter, the PC 75 ends this operation.

  FIG. 7 is a diagram showing a screen of the display 73 on which an image transmitted from the vehicle-mounted device 10 and a non-passing event are displayed. On the screen of the display 73, an image 80 taken by the camera 55 at the scheduled time of passing the bus stop b and the fact that the bus stop b has not passed is displayed. Further, an image 81 taken by the camera 55 is displayed at the time when the bus stop g has not passed and the scheduled time of passing the bus stop g.

  According to the bus operation management system of the present embodiment, it can be confirmed in real time that the bus has stopped at the bus stop and has passed. Also, if you run too far without stopping at the bus stop, you can confirm that you have not passed. Therefore, bus operation can be managed efficiently.

  It is also possible to verify later by recording the passage or non-passage of the bus stop. In addition, when it has not passed, data indicating that it has not passed is transmitted to the office-side PC, so that the manager on the office side can grasp the bus operation status in real time.

  Furthermore, since the image taken by the camera is also transmitted, the manager on the office side can grasp the situation of the bus when it has not passed the bus stop. For example, it is possible to know a situation in which a bus is involved in a traffic jam, a situation in which a road is detoured due to an accident, or the like.

  Moreover, when it is in the communication area | region set to the bus stop, since an onboard equipment becomes communicable with the narrow area communication path side radio | wireless apparatus, it can target only the bus | bowl in the narrow range before a bus stop.

  The present invention is not limited to the configuration of the above-described embodiment, and any configuration that can achieve the function of the configuration of the present embodiment is applicable.

  For example, in the above embodiment, the case where the bus operation is managed is shown, but the present invention is not limited to the bus, and can be applied to an operation management system in which various vehicles travel on a specific route. is there.

  In the above embodiment, the current position of the bus is acquired by the GPS receiver. However, the current position may be acquired by performing wireless communication with the radio base station. Moreover, although the stop of the bus was detected by the vehicle speed sensor, it can also be detected by tracking the GPS position information.

  In the above embodiment, the vehicle-mounted device confirms that the bus is in the passing area set at the bus stop by performing narrow-area communication with the narrow-area communication path side wireless device. Not limited. For example, a bar code may be installed in a passing area of a bus stop, and the bar code reader mounted on the bus may read the bar code for confirmation. Alternatively, the light installed at the bus stop may emit light having a specific pattern at the estimated arrival time, and the light receiver mounted on the bus may receive the light.

  INDUSTRIAL APPLICABILITY The present invention is an on-vehicle device mounted on a vehicle, which is useful because it can correctly confirm that the vehicle stops and passes at a predetermined point.
