Further, the bus is provided with a computer 12, a bus stop passage information generation circuit 14, an in-car congestion information generation circuit 15, and an emergency information generation circuit 16. The bus stop passage information generation circuit 14 transmits information indicating that the bus has passed to the server 30 via the computer 12 and the communication device A11 when the bus passes one bus stop. The in-car congestion information generation circuit 15 transmits a congestion signal by a bus driver's switch operation, or mechanically determines the congestion state based on a video taken inside the bus car, and determines the number of passengers on the bus. The information is transmitted to the server 30 via the computer 12 and the communication device A11, for example, for determining the congestion status based on the number of passengers with respect to the number of passengers. The emergency information generation circuit 16 transmits emergency information to the server 30 via the computer 12 and the communication device A11 based on the switch operation of the bus driver when a trouble such as a bus failure or a passenger's illness occurs. Yes.

On the other hand, the bus stop 20 is provided with a communication device B23 as shown in FIG. 4, and this communication device B23 can communicate with the server 30 via the packet communication network in the same manner as the communication device A11. Yes. The bus stop 20 is provided with a bus stop indicator 22. The bus stop indicator 22 is composed of a liquid crystal display panel, and is installed so that information can be displayed for customers waiting for the bus at the bus stop. The bus stop 20 corresponds to a small-scale bus stop in the present invention.
FIG. 14 shows an example of the appearance of the bus stop 20. In this case, the bus stop 20 is provided with a pillar 25 on a concrete base 21 and provided with a display board 26. The display board 26 shows a timetable and a route map, and the bus stop indicator 22 described above. Is provided. The bus stop indicator 22 has a size of about 70 mm 2 and displays a QR code (registered trademark) which is a two-dimensional code.
At the upper end of the display board 26 of the bus stop 20, a gutter 27 is provided in the horizontal direction. The gutter 27 is provided with a solar cell on its upper surface, and the electric energy generated by the solar cell is stored inside the gutter 27. A lithium ion battery for storing electricity, a computer 24, a speaker, and a communication device B23, which will be described later, are provided, and a white LED (light emitting diode) for illuminating the display plate surface is provided on the lower surface of the basket 27. An antenna 28 connected to the communication device B23 is provided at the upper end of the display board 26 so as to be able to communicate with the packet communication network.
As shown in FIG. 4, the bus stop indicator 22 displays information in accordance with a command transmitted from the server 30 via the computer 24 and the communication device B23.

  A management terminal 40 is connected to the server 30, and information selected by the administrator through the management terminal 40 can be displayed on the bus stop display 22.

FIG. 5 shows the processing performed in the server 30. First, in step S21, it is determined whether or not passage information is generated from the bus stop passage information generation circuit 14, and if so, step S21 is executed. An affirmative determination is made, and in step S22, the bus schedule is compared with the time when the passing information is generated, that is, the passing time. As a result of the comparison, it is determined in step S23 whether or not there is a predetermined delay in the passage time with respect to the diamond. If there is no delay, the approach information is transmitted in step S24. This approach information is information indicating that the bus is approaching the next bus stop, and is transmitted to the corresponding bus stop.
On the other hand, if there is a delay, an affirmative determination is made in step S23, and an estimated arrival time at the next bus stop is calculated in step S25. In step S26, the arrival information is added to the approach information similar to that in step S24 and transmitted. If the passage information is not received in step S21, a negative determination is made in step S21, and the processing from step S22 to step S26 described above is skipped.

  Next, in step S29, it is determined whether or not in-vehicle congestion information is received. If the congestion information is transmitted from the in-vehicle congestion information generation circuit 15 mounted on the bus and received, step S29 is affirmatively determined, and the display information related to the congestion displayed on the respective indicators 13 and 22 in step S30. Send. The display information in this case may be character information. If the congestion information is not received, a negative determination is made in step S29, the process in step S30 is skipped, and it is determined in step S31 whether or not emergency information is received from the emergency information generation circuit 16 mounted on the bus. The If the emergency information has been received and the determination in step S31 is affirmative, in step S32, details of the emergency information, for example, whether the bus is faulty, where is the faulty part, or if the passenger is in trouble are identified. Send. This transmission information is displayed on the screen of the management terminal. Based on the information, the manager selects display information to be displayed on the bus stop indicator 22 at the management terminal and transmits it to the server 30. Here, the display information is text information that corresponds to the emergency information when the administrator sees the content of the emergency information. Next, in step S33, it is determined whether display information has been received. If this display information is received and step S33 is affirmed, character information is transmitted as display information in step S34. If urgent information has not been received, a negative determination is made in step S31, the processing after step S32 is skipped, and if no display information has been received, a negative determination is made in step S33, and the processing returns to step S32. Wait for display information to be received.

  FIG. 6 shows processing performed by the computer 12 mounted on the bus. First, in step S92, the name of the bus stop to be stopped next is displayed on the on-vehicle display device 13 as is normally done in the bus. Yes. In the next step S93, it is determined whether or not the bus stop passage information is input from the bus stop passage information generation circuit 14. If the bus stop passage information has been input, the determination in step S93 is affirmative. In step S94, the communication device A11 transmits the bus stop passage information together with the bus identification code. If the bus stop passage information is not input, a negative determination is made in step S93, and the process in step S94 is skipped.

In the next step S99, it is determined whether or not congestion information is input from the in-vehicle congestion information generation circuit 15. If the congestion information has been input, an affirmative determination is made in step S99, and the congestion information is transmitted to the server 30 via the communication device A11 in step S100.
If the bus congestion information has not been received and the determination in step S99 is negative, the processing in step S100 is skipped, and in the next step S103, it is determined whether or not emergency information is input from the emergency information generation circuit 16. . If the emergency information is input and step S103 is affirmed, the emergency information is transmitted to the server 30 via the communication device A11 in step S104. If the bus emergency information has not been received and the determination in step S103 is negative, the processing in step S104 is skipped.

Next, FIGS. 7 and 8 show processing of the computer 24 at the bus stop. First, in step S41, the approach information is received from the server 30, and it is determined whether or not the bus has approached the bus stop up to a predetermined distance. . Whether or not the vehicle has approached a predetermined distance is substituted by the elapsed time since the reception of the approach information. If the approach information is received and the vehicle is approaching a predetermined distance and the determination in step S41 is affirmative, whether the approaching bus is a daytime bus or a nighttime bus is transmitted from the bus in step S42. It is determined based on the identification code. If the approaching bus is a daytime bus and an affirmative determination is made in step S42, it is determined in step S43 whether the approaching bus is a continuation bus or a final bus. If it is a continuation bus and step S43 is affirmed, it is determined in step S44 whether or not an approach flag is set. Initially, since the approach flag is not set, a negative determination is made in step S44, and the approach information is displayed in step S47. That is, the route of the bus is identified based on the identification code of the approaching bus, and a command is transmitted so that the bus stop indicator 22 is displayed together with the destination of the bus.
The display command to the bus stop indicator 22 in step S47 is converted into a QR code that is a two-dimensional code, and is displayed on the bus stop indicator 22 as shown in FIG. Passengers who wait for boarding at the bus stop 20 read the QR code displayed on the bus stop indicator 22 with the camera of the mobile phone (two-dimensional code reader) 50, so that the approach information is displayed on the screen of the mobile phone 50 as shown in FIG. Can see. The process of converting the character information of the display command into the QR code is performed by conversion software in the computer 24 at the bus stop, and the process of converting the QR code read by the mobile phone 50 into the character information as shown in FIG. It is done by the conversion software inside. Since these conversion softwares are well known in the art, a detailed description is omitted.
As described above, the bus approach information at the bus stop 20 is displayed by the QR code, and the display area can be smaller than that displayed by using characters and drawings, so the bus stop indicator 22 can be small, and thus the power consumption. The solar battery and the lithium ion battery, which are power supply devices for driving the bus stop indicator 22, can be small. Therefore, even if it is applied to a small bus stop with few passengers, the cost for the facilities can be reduced and the profitability is good.
Thereafter, an approach flag indicating that the display of approach information has been completed is set in step S48.

  When the approach information is displayed in this way and step S44 is processed after the approach flag is set, step S44 is affirmed, and in step S45, a command for displaying the approach information in a superimposed manner is transmitted. This is the state where the approach information has already been displayed on the bus stop indicator 22, and when the subsequent bus approaches the bus stop, the approach information of the subsequent bus is displayed superimposed on the approach information of the preceding bus. ing. On the bus stop indicator 22, an indication that the destination is approaching each of the two buses that are approaching the bus stop is displayed by a QR code. The QR code in FIG. 10 and the approach information display in FIG. 11 are examples of displaying information on two buses. Next, in step S46, the display flag is set so as to overlap. This flag stores that a plurality of pieces of approach information are displayed on the bus stop indicator 22 as described above.

  If it is determined in step S43 whether or not the bus is a continuation bus, if the determination is negative in step S43 for the final bus, the bus stop display 22 is displayed in step S49 as the final bus. In the bus stop indicator 22, it is added to the approach information that the approaching bus is the last bus and is displayed by the QR code. In the next step S50, the final bus flag is set. This flag stores that the approaching bus is the last bus.

  If it is determined in step S42 whether the bus is a daytime bus, if it is a night bus and the determination in step S42 is negative, it is determined in step S51 whether the bus is a continuation bus. The process of step 51 is exactly the same as the process of step S43 described above, and after step S51, the processes of step S52 to step S58 are also displayed on the bus stop display 22 with respect to the processes of step S44 to step S50 described above. The only difference is the approach information for daytime and nighttime use. Therefore, the description of the same part is omitted here.

  After the above processing is completed, an approach voice guidance is commanded in step S60. In addition to the above-described display, this also guides the approach of the bus even by voice by a speaker installed at the bus stop.

In step S61, it is determined whether bus congestion information is received from the server 30 or not. If the congestion information is received, an affirmative determination is made in step S61, and in step S62, an indication that the approaching bus is congested is additionally displayed on the bus stop indicator 22. If the congestion information has not been received and the determination at step S61 is negative, the process at step S62 is skipped and the process at step S63 is executed.
When the bus approach information is not received from the server 30 in the process of step S41 described above, or when the bus is not approaching the predetermined distance, a negative determination is made in step S41, and each of the processes described above is skipped. The process of step S63 in FIG. 8 is executed. Here, it is determined whether or not the bus has passed the bus stop. Although not shown, the bus stop has a circuit that generates a signal by detecting passage of the bus, and determines whether a bus passage signal is received from the circuit. Instead of providing such a circuit, an operation signal of a switch operated by a bus driver may be used as a bus stop passage signal. At this time, if the bus has not passed and the determination in step S63 is negative, it is determined in step S71 whether the approach flag is set. At this time, if the approach display is not performed on the bus stop indicator 22 and the approach flag is not set, a negative determination is made in step S71, and a timetable display is executed in step S67. The timetable is displayed on the bus stop display 22 as shown in FIG. 12, and displayed on the screen of the mobile phone 50 that has read the QR code as shown in FIG. The display performed on the screen of the mobile phone 50 displays the departure time of the bus at the bus stop.
In the next step S68, the approach flag is reset. If an affirmative determination is made in step S71, the processes in steps S67 and S68 are skipped.

If the bus passes and the determination in step S63 is affirmative, it is determined in step S64 whether or not the final bus flag is set. If the final bus flag is not set, a negative determination is made in step S64, and it is determined in step S65 whether the approach flag is set. If the approach flag is not set, a negative determination is made in step S65, and the processes in steps S67 and S68 described above are executed.
At that time, if the approach information is displayed on the bus stop indicator 22 and the approach flag is set, an affirmative determination is made in step S65, and it is determined in step S66 whether or not the display flag is set repeatedly. When a plurality of approach information is displayed on the bus stop display 22 in an overlapping manner, an affirmative determination is made in step S66, and the approach information displayed earlier is deleted from the plurality of approach information in step S69. This is because the preceding bus approach information is erased because the preceding bus has passed the bus stop, and only the following bus approach information is displayed on the bus stop display 22. In the next step S70, the display flag is reset again. If a negative determination is made in step S66, the processes of steps S67 and S68 described above are executed.
If an affirmative determination is made in step S64, the final bus has passed the bus stop, so the power of the bus stop indicator 22 is turned off in step S72, and all the indications on the bus stop indicator 22 are erased. In step S73, the final flag representing the final bus is reset.

  Next, in step S78, it is determined whether or not emergency information is received from the server 30. If the emergency information is received, an affirmative determination is made in step S78, and the emergency information is displayed as a QR code on the bus stop display 22 in step S79. If the bus emergency information has not been received and the determination in step S78 is negative, the processing of step S79 is skipped, and the processing of the computer at the bus stop ends.

  FIG. 9 shows the processing of the management terminal installed at the bus sales office together with the server 30. First, in step S81, the same content as that displayed on the bus stop indicator 22 on the screen of the management terminal is displayed in character display. In the next step S82, it is determined whether or not emergency information is received in the server 30, and if emergency information is received, an affirmative determination is made in step S82 and an emergency call is made to the administrator in step S83. . This emergency call is for notifying the administrator that an emergency has occurred. In the next step S84, it is determined whether or not an input made by selecting from a plurality of display items in the management terminal as display information to be displayed on the bus stop indicator 22 by the administrator receiving an emergency call is completed. The Here, the information selected by the management terminal is displayed on the bus stop display 22 by the manager with respect to the contents of the emergency information, for example, whether the bus is faulty, where is the faulty part, or whether the fault is in the passengers. This is character information that is selected and inputted by determining display information to be displayed. Steps S83 and S84 are repeated until the input is completed. When the input is completed, an affirmative determination is made in step S84, and the display information input in step S85 is transmitted. Based on this transmission, the emergency information is displayed on the bus stop indicator 22.

As described above, according to the above embodiment, when a bus approaches the bus stop 20, the bus stop indicator 22 displays that the bus is approaching and also displays a voice so that the passengers can see the bus operation status. Can be informed appropriately. In addition, since the display of the bus stop indicator 22 is performed by a QR code, a small display can be used and power consumption is small, so that a solar cell or a lithium ion battery for operating it can be small.
In addition, the bus congestion status and emergency information are also displayed at the bus stop so that passengers can appropriately respond to these situations.

In the above embodiment,
The server 30 and the management terminal 40 correspond to the control unit of the present invention, the solar battery and the lithium ion battery correspond to the power supply apparatus of the present invention, and the processing of step S21 and step S24 is performed by the display command means of the present invention. Correspondingly , the process of step S47 corresponds to the approach command means of the present invention .

In the above-described embodiment, a GPS (Global Positioning System) device is not used, but the GPS device is mounted on the bus so that the travel position of the bus can be grasped in more detail, and the bus stop passage information and the GPS device can be obtained. It is also possible to generate bus approach information at a more accurate timing by combining with bus position information based on the above. In addition, the bus stop indicator uses a small indicator that displays with a QR code as in the above embodiment for a small bus stop with few passengers, while characters and characters are displayed on a large bus stop with many passengers. A large display that can be easily understood using a figure may be used, and a bus stop display may be properly used in the same bus route.
In addition, the present invention can be implemented in various forms within the scope of the inventive idea.
