Description

  The present invention receives operation status information from an in-vehicle device installed on each bus at the bus management center, and transmits the received operation status information to each bus stop from the bus management center, thereby displaying the bus status on the display panel of each bus stop. The present invention relates to a bus operation management system that displays operation status.

  A general route bus is operated based on one day of staff data (operation schedule data) indicating at which stop the bus arrives at what time. The bus management center that manages bus operations manages bus stop departure / arrival times based on this staff data, and the timetable posted at each bus stop also corresponds to this staff data.

  During normal bus operation, the driver manages the operation based on this staff data, so that delays and early departures of the bus can be prevented. However, since traffic conditions change due to traffic congestion, road surface construction, etc., it may be difficult to operate according to staff data. Therefore, when a bus arrives at a bus stop later than scheduled due to traffic congestion or the like, passengers at the bus stop need to wait for the bus without knowing how late the bus will arrive after the scheduled time has passed.

  In recent years, in order to reduce such anxiety of passengers, a bus operation management system has been devised that presents bus operation information such as bus delay time on a display panel of a bus stop (for example, Patent Document 1 and Patent Document 2). reference).

  In the bus operation management system, a GPS antenna or the like is installed on the bus, and the traveling position of the bus detected by the GPS antenna and its detection time are transmitted to the bus management center through wireless communication means or the like. The bus management center calculates the transit time on the bus route based on the received bus location information and detection time, and compares it with the planned transit time recorded in the staff data to determine the bus delay status. Judging.

If it is determined that the bus is delayed, the bus management center transmits the delay time information to each bus stop using wireless communication means, etc., and the received delay time information is displayed on the bus stop display panel or the like at each bus stop. Let

  However, in the bus operation management system as described above, the position information and detection time information of all buses are concentrated and transmitted to the bus management center. For this reason, the bus management center must determine the delay time of all the buses, and the processing load of the bus management center tends to increase. When the processing load of the bus management center is increased, it takes time to determine the delay time, and there is a problem that the delay time of the bus cannot be displayed quickly at the bus stop.

  In addition, this trend increases as the number of route buses operated and the scale of operation increase, so the bus company must pay additional facilities to improve and stabilize the system processing speed. There was a problem of not becoming.

  The present invention has been made in view of the above problems, and is capable of quickly showing the bus operation status to passengers waiting for the bus at the bus stop while reducing the processing burden at the bus management center. Provide a system.

  In order to solve the above problems, a bus operation management system according to the present invention receives operation status information from an in-vehicle device installed in each bus at the bus management center, and receives the received operation status information from the bus management center to each bus stop. A bus operation management system for displaying the bus operation status on the display panel of each bus stop, wherein the in-vehicle device detects the travel position of the bus, and the detection of the travel position. A time detecting means for obtaining a time in time, a recording means for recording the scheduled operation data of the bus, a current position on the bus operating route is determined from the travel position detected by the position detecting means, and the recording means Comparing the estimated passage time of the current position obtained from the scheduled operation data recorded in the time and the time detected by the time detection means Therefore the operation status determining means for determining the operation status of the bus, characterized in that it comprises a transmitting means for transmitting the operation status information determined by 該運 row status determination means to said bus management center.

  In addition, the bus operation management system according to the present invention receives operation status information from an in-vehicle device installed in each bus at the bus management center, and transmits the received operation status information from the bus management center to each bus stop. A bus operation management system for displaying a bus operation status on a display panel of each bus stop, wherein the in-vehicle device detects that the bus has arrived / passed at the bus stop, and arrived / passed at the bus stop. A time detection means for determining the time taken, a recording means for recording the bus operation schedule data, and an operation schedule recorded in the recording means when it is detected by the bus stop detection means that the bus has arrived or passed through the bus stop. By comparing the estimated time of passage of the bus stop determined from the data with the time detected by the time detection means, The operation status determination means for determining may be characterized in that it comprises a transmitting means for transmitting the operation status information determined by 該運 row status determination means to said bus management center.

  In the bus operation management system according to the present invention, the operation status of the bus is determined not by the bus management center but by an in-vehicle device installed in each bus, so that the processing load at the bus management center can be reduced.

  In addition, the bus management center only needs to transmit the bus operation status information received from each in-vehicle device to each bus stop as it is, so it is possible to quickly convey the operation status such as early departure / delay time of the bus to each bus stop. .

  Hereinafter, a bus operation management system according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration of a bus operation management system. The bus operation management system 1 includes an in-vehicle device 2 installed on each bus and a bus management center 3 that manages operation of a plurality of buses.

  The in-vehicle device 2 includes a GPS detector 10, a communication device 11, a recording device 12, and a bus control unit 13.

  The GPS detector 10 includes a GPS antenna 10a and a detection main body device 10b. The GPS antenna receives a GPS signal from a GPS satellite, and based on the GPS signal received by the GPS antenna, the detection main body device 10b obtains the traveling position of the bus and its detection time.

  The recording device 12 includes storage means such as a hard disk and a large-capacity memory, and records staff data (operation schedule data) 12a indicating a bus operation schedule. The staff data 12a is data in which the schedule of operation of each bus is defined. The driver checks the staff data 12a to manage the bus operating route, arrival / departure time, and the like.

  The communication device 11 is used for communicating with the bus management center 3. The communication device 11 communicates information with the bus management center 3 using a wireless communication technology such as a mobile phone, PHS, and wireless LAN.

  The bus control unit 13 is a processing unit including a CPU, a memory, and the like that are not shown. The bus control unit 13 determines the bus operating status by comparing the bus travel position and detection time obtained by the GPS detector 10 with the information of the staff data 12a recorded in the recording device 12.

  FIG. 2 is a flowchart showing a bus operation status determination process in the bus control unit 13.

  First, the bus control unit 13 acquires arrival / passage information of a bus stop (step S.1). The arrival of the bus stop is determined according to the operation of the door opening / closing operation button 14a operated by the driver. Based on the opening / closing operation button 14a being operated and the door opening at the bus stop, the bus control unit 13 determines the arrival of the bus stop. When the bus passes without stopping at the bus stop, it is determined whether or not the bus stop has passed based on the operation of the bus stop guide button 14b operated by the driver immediately after passing the bus stop. When the bus stop guidance button 14b is operated, voice guidance and voice advertisement for the next bus stop are started, and the name of the next bus stop is displayed on the guidance display board in the vehicle.

  When the arrival / passage information of the bus stop is acquired, the bus control unit 13 acquires the travel position and detection time of the bus from the GPS detector 10 (step S.2). The bus control unit 13 can obtain the arrival / passage time of the bus stop by acquiring the detection time immediately after acquiring the arrival / passage information of the bus stop.

  Then, the bus control unit 13 refers to the staff data recorded in the recording device 12 to obtain the estimated arrival time of the bus stop (step S.3), and compares the estimated arrival time with the detection time to determine the bus status. The operation status, specifically, how fast the bus departed from the bus stop and how late the bus arrived (step S.4).

  As described above, the bus in-vehicle device 2 determines the early departure / delay of the bus, whereby the processing conventionally performed in the bus management center 3 can be shared with each in-vehicle device 2, and the processing load in the bus management center 3 is increased. Can be reduced.

  The bus control unit 13 transmits the obtained early departure / delay time of the bus (operation status information) to the bus management center using the communication device 11 (step S.5).

  The bus management center 3 receives operation status information related to early departure / delay of each bus, and distributes the received operation status information to each bus stop 4 using wireless communication means. At each bus stop 4, the operation status information received from the bus management center 3 is displayed on the display panel of the bus stop 4, and the passengers waiting for the bus at the bus stop are informed of the delay time of the bus.

  As described above, in the bus operation management system 1 according to the present invention, the bus operation status determination (early departure / delay time determination) is performed not by the bus management center 3 but by the in-vehicle device 2 installed in each bus. The processing load in the bus management center 3 can be reduced.

  In addition, since the bus management center 3 only needs to distribute the bus operation status information received from each in-vehicle device 2 to each bus stop 4 as it is, it is possible to promptly inform the bus stops 4 of the early departure / delay time of the bus. .

  The bus operation management system according to the present invention has been described above with reference to the drawings. However, the bus operation management system according to the present invention is not limited to the above-described embodiment. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  For example, in the above-described embodiment, when the arrival / passage information of the bus is acquired, the detection time is acquired by the GPS detector 10 to determine the arrival / passage time of the bus stop. Regardless of the arrival / passing timing of the bus stop, the GPS detector 10 may detect the bus travel position and detection time periodically (at regular intervals, for example, every minute).

  When the traveling position and detection time of the bus are regularly detected, the bus control unit 13 predicts the arrival time of the next bus stop 4 based on the traveling position and detection time, and the predicted time and By determining the time difference from the scheduled arrival time recorded in the data 12a, the in-vehicle device 2 can determine the bus operation status. Even in such a case, it is not necessary to make a bus operation status determination (early departure / delay time determination) in the bus management center 3, so that the processing load in the bus management center 3 is reduced as in the above-described embodiment. It becomes possible.

It is a block diagram which shows schematic structure of the bus operation management system which concerns on embodiment. It is a flowchart which shows the bus operation condition judgment process of the vehicle-mounted apparatus which concerns on embodiment.
