Description

[Detailed Description of the Invention] The present invention is directed to a bus guide display system in a bus terminal.

To make it easier for users to use the bus by displaying to people waiting for a bus near a bus stop whether a bus is coming or not, and to reduce the sense of distrust and crowding while waiting for a bus as much as possible. Can be done.

Here, if there is one bus system on one route, it is relatively easy to display it, but when buses of multiple systems run on multiple routes and use multiple stops, such as at a bus terminal, how to display it. The present invention provides a system that satisfies these points, and one embodiment thereof will be described below with reference to the drawings.

FIG. 1 shows the layout of the entire system, with arrows 1 to 3 indicating routes on which buses head toward terminal 7, and arrows 4 to 6 indicating routes departing from terminal 7.

8 is a roadside device installed on the road of Route 1 entering Terminal 7, and is a roadside antenna 81. It consists of an electromagnetic induction type receiver 82.

83 indicates a communication area. 9 has an on-board transmitter 92 having an on-board antenna 91 that is electromagnetically coupled to a road antenna 81 when the bus runs on the road and passes through a communication area, as shown in FIG.

In this case, the transmitter 92 has a code setting device (not shown) for setting a code signal so that a code signal corresponding to the bus system can be set, and when the last bus is the last bus, last bus information can also be set. It looks like this.

The transmitter 92 may be started in conjunction with the engine key, or may be started manually, and the signal is transmitted when the on-vehicle antenna 91 near the roadside device 8 enters the communication area where it electromagnetically couples with the roadside antenna 81. Based on the signal from the roadside receiver 82, bus information is transmitted for a certain period of time.

In the terminal 7, 10 is a bus stop having one or more bus stops (bus departure and arrival points), and at its entrance there is a terminal receiving device 11 consisting of an antenna 12 and a receiver 13 similar to the on-road device 8. On the other hand, each bus stop (only one is shown in Figure 1)
A display 14 is provided at the.

FIG. 3 is an enlarged view of that part, and the display 14 is further divided into displays A, B, and C as shown in FIG. It is now possible to do so.

3. As shown in FIG.
are respectively provided and are coupled to a central processing unit 16.

The remaining central processing unit 16 is connected to a modem 161 as shown in FIG.
．． The main components are a serial/parallel conversion section 162, an arithmetic processing section 163, and a storage device 164, and control the display 14.

That is, the bus information from the roadside receiving device 8 and the terminal receiving device 11 is also checked, and it is possible to determine which bus system the information is from, to determine whether the information is for the first time or today), and to determine whether it is the last bus information. No need to worry, now display 14
Display A.

You will need to control the B button and C.

FIG. 6 shows this hardware configuration, where 165 is a discriminator, and 166 is a display A based on the first bus information, for example, "■ Yado 00 Roro line", that is, the stop number and system number.

A control unit that lights up information such as the destination and turns off the light when the last bus information is displayed, and is also useful for road bus information.Display B
``The next bus left △△△△'' and the flash of display C are turned on, and the terminal bus information is also controlled to turn off the lights and display B.

It consists of a control section 167 that operates the notification sound generating device 500 for a certain period of time at the same time as the display of C starts, and the control section 1.67
has, for example, an addition/subtraction counter function, and is designed to eliminate erroneous display when road bus information is entered while display B continues to be lit.

(Details on this point will be described later.) Next, the operation of the following configuration will be briefly explained.

1. The bus information code of the on-board transmitter 92 is set in advance by an attendant or the driver at the garage, business office, operation area, etc. where the bus departs for Taniminal 7.

Here, the code is set according to the route or destination from which the bus departs from the terminal 7, regardless of which route or other road the bus is heading towards.

The last bus code is set for the last bus.

Therefore, when the bus 9 having such an on-board transmitter 92 passes through the roadside receiving device 8 and the terminal receiving device 11 on the road, the receiving device 8.11 tends to receive the bus information.

On the other hand, we will explain how to control the display on the display 14 based on the bus information from the receiving devices 11 and 8.
A in Figure 7 shows the bus 9 arriving at the bus stop at terminal 7 without passing through the on-road receiver 8, and leaving after a certain time; the yokozuna represents time, and the vertical axis represents distance. The display status of the display is shown at the top.

In this case, only display A is in a lighting display state.

The same exit shows the state of arriving at the terminal 7 after passing through the point of the roadside reception device 8, and when the roadside reception device 8 receives bus information, display A is displayed.

A light is displayed when the B and C power is selected, and a notification sound is generated to notify the start of lighting.

Display B here. C turns off when the terminal receiving device 11 receives bus information from the bus 9.

After that, depending on the first bus, display A will continue to be displayed, but display B,
C and the notification sound are controlled based on information from the terminal reception point on the road.The notification sound is controlled by a drive circuit and operates once or multiple times in succession.

However, there may be cases where there are multiple buses of the same system or destination between the on-road reception point and the terminal reception point due to short driving intervals, and in such cases, the central processing unit 16 calculates the number of buses of the same system. is counted, and when there is a bus between the pixels, displays B and C are kept on, and when there is no bus between the pixels, the displays B and C are turned off as shown in FIG.

In this case, this process is carried out by the arithmetic processing unit 163 and the storage device 164.
However, as explained with reference to FIG. 4, the terminal bus information continues to be displayed when the terminal bus information corresponds to the number of on-road bus information added to the control unit 167.

After the departure of the last bus, the display A will be lit and displayed.In order to avoid misunderstandings among users, by setting the last bus information code, the display A will be displayed as shown in Figure 9. When the last bus information is received at the terminal reception point, the light goes out along with display B.

If the bus breaks down as shown in Figure 10 without reaching Terminal 7 even though it has passed the receiving point on the transfer route, the broken bus will not arrive at bus stop 10 of Terminal 7, so display B will continue to light up. However, assuming that there is no overtaking of buses on the same route, the central processing action 16 will be taken when the following bus or alternative bus arrives at the terminal reception point.
It is determined that the vehicle is overtaking, and indicators B and C go out.

In the unlikely event that the last bus breaks down, service will not be canceled and a replacement bus will be provided.

[However, in relation to the case in FIG. 8, the central processing unit 16
It is desirable to press the button in such a way that this judgment can be easily made.

] The explanation above has been given using one system as an example, but if there are multiple systems, the central processing unit 16 can determine which system or destination bus information is, and the lighting control of the display 140 can be performed based on that information. .

Figure 4a shows the case where there is one display 14 for one route or destination, but when there are multiple destinations, a fourth display 14 is displayed to show which destination bus is approaching. It is preferable to provide means for flashing the display C in front of the destination display as shown in the figure.

Further, the notification sound generating device 500 may be formed by an oscillator,
It may be provided outside the display 14.

In addition, although one terminal receiving device 11 is provided for each 10 stops, even if the terminal receiving device 11 is provided by the number of bus systems (-N devices per stop), all buses entering terminal 7 will receive only one terminal receiving device 11.
If it is located in one place, one piece per terminal □ is sufficient.

As explained above using the embodiment, in the electromagnetic induction type communication in which code signals are sent from the bus 9 to the on-road device 8, the communication area can be limited by electromagnetic coupling between the on-vehicle and on-road antennas. The probability of simultaneous reception is low, and the effects of reflection and shielding are relatively small.

That is, while it is easy to separate the upper and lower lines, there is little influence of reflection from other vehicles or buildings/structures, and there is no possibility of simultaneous reception even for parallel vehicles on a three-lane road, for example, if the head-to-head distance is 3 m or more.

Electromagnetic induction antennas have a high degree of freedom in installation because they are relatively unaffected by nearby objects.

Further, since the bus information from the bus 9 requires lighting control of the clearance indicator 14, the service to the users can be provided accurately and easily.

As shown in Figs. 7 to 10, the lighting time of display B depends on the distance between the on-road reception point and the evening/minal reception point, and the path 90.
It depends on the driving speed, but if there is traffic jam between them, T1. (To<TI) may occur.

Therefore, in order to make the display time of display B almost the same, the time required from the previous road reception point to terminal reception point 1 is memorized and display B is displayed.

By delaying the display start of C by al and a2, the display time of displays B and C becomes close to a fixed time,
The degree of distrust towards people waiting for the bus will be reduced.

As soon as the last bus information is displayed, a display may be provided to notify that the last bus has departed, as shown in the upper right corner of Figure 4.

This will turn on and off for a certain period of time.
