Abstract

PURPOSE:To accurately inform the name of the next bus stop to a passenger by providing a bus stop name transmitter at every bus stop and a bus stop name display device at each bus, and automatically informing the name of the bus stop scheduled to stop next without interposing the operation of a driver. CONSTITUTION:When a route bus on which the bus stop name display device is loaded approaches the bus stop, a wave emitted from the antenna 3 for transmission of the bus stop name transmitter is inputted to a reception part 5 via an antenna 4 for reception, and is recovered to a code by a decoder 8. A CPU 7 retrieves the data of the bus stop next to the bus stop with the code sent from the bus stop name transmitter from a memory 8. When the route bus is separated from the bus stop and reception information from the reception part 5 disappears, the CPU 7 displays the name of the next bus stop on a display unit 9, and also, the name of the next bus stop is announced from a speaker 11 by controlling a tape recorder 10. In such a way, the name of the bus stop scheduled to stop next can accurately be informed to the passenger.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a system for notifying passengers of the name of the next stop on a route bus.

``Prior art'' - In general, there are two ways to notify passengers on a route bus of the name of the next stop, other than when the driver or the like tells it verbally:
There are two methods: an audio method such as a pre-recorded RF cassette tape, and a visual method such as lighting up a lamp on a display board installed at the front of the bus. Hands pressed push buttons one by one to activate these devices.

[Problems to be Solved by the Invention] With the conventional method described above, passengers may forget to press the button for bus stop notification or press the button incorrectly, and the announcement may not be heard due to the noise. There are disadvantages such as getting off at the stop or missing the bus.

[Means for Solving the Problems] The bus stop name transmission/display system of the present invention includes: a bus stop name transmission device installed at each bus stop to transmit the bus stop name; and a bus stop name transmission device installed inside the bus. It consists of a bus stop name display device that receives the pass stop name transmitted from the bus stop name transmitting device and displays the name of the pass stop at which the next stop is scheduled to be made to the passengers. The bus stop name display device includes a code generator for encoding, a transmission antenna, and a transmitter that converts the generated code into radio waves for transmission and emits them with the transmission antenna. A receiving antenna that receives radio waves emitted by a receiver, a receiver that detects and amplifies the received radio waves, a decoder that decodes codes from the detected and amplified radio waves, and an audio and visual display of bus stop names. and a control section that causes the display to display the path stop name for the next stop P on the display based on the decoded code.

[Function] Each time a bus operating on a route approaches a bus stop, the bus stop name display device receives radio waves containing a code indicating the name of the bus stop emitted from the bus stop name transmitter, Say the name of the next pass stop by voice and/or
Alternatively, since it is visually displayed, there is no need for any intervention by the bus driver, and passengers are accurately notified of the name of the bus stop where the bus is scheduled to stop next.

[Example] Next, an example of the present invention will be described with reference to the drawings.

Figure 1 shows the bus stop name transmission/display system of the present invention.
- In the embodiment, (1) in the same figure is a block diagram of a bus stop name transmitting device, and (2) in the same figure is a block diagram of a bus stop name display device.

As shown in Fig. 1 (1), the bus stop name transmitting device is
It consists of a code generator 1, a transmitter 2, and a transmitting antenna 3,
They will be installed at each bus stop along the route.

The code generator 1 has a ROM in which a set of route identification code and a number assigned to each stop on the route is written in advance as a digital code for each bus stop,
During operation, the ROM is read out and digital codes are sent to the transmitter 2 as a serial signal. The transmitter 2 generates radio waves with a frequency determined for each route, modulates the serial signal sent from the code generator 1 to produce a signal radio wave, and sends this signal radio wave to the side of the road where the bus passes through the transmitting antenna 3. fire towards.

The bus stop name display device is as shown in Figure 1 (2).
It consists of a receiving antenna 4, a receiving section 5, a decoder 6, a CPU 7, a memory 8, a display 9, a tape recorder IO, and a speaker 11, and is installed in each bus operating on this route.

The receiving antenna 4 captures the signal radio waves emitted from the bus stop name transmitting device and transmits them to the receiving section 5. Receiving section 5
detects and amplifies the received radio wave and sends it to the decoder 6 as a serial digital signal. The decoder 6 decodes the serial digital signal into the same digital code as the code of the code generator 1, and records it in the RAM included in the decoder 6. The memory 8 is a ROM memory in which data for all bus stops are written in advance, including a code for each bus stop and data for displaying the stop name. The CPU 7 detects the presence or absence of radio wave reception in the receiving section 5, searches the 5-set number unit 6 and the memory 8 for data on the corresponding path stop name, and controls the operation of the display 9 and tape recorder IO. The indicator 9 is provided with a lamp for each stop, and the corresponding lamp is turned on under the control of the CPU 7. tape recorder [0
is a playback-only cassette tape recorder, into which is inserted a cassette tape with audio recordings of the bus stop names on the route, one by one, in the order of passing.

Next, the operation and operation of this embodiment will be explained.

The bus stop name transmitting device constantly emits signal radio waves containing the bus stop code during the time when route buses are in operation. Constant firing here does not necessarily mean continuous firing, and intermittent firing using a timer etc. is also acceptable, but it is necessary to be able to receive the radio waves of the bus stop at least once while the route bus passes the stop. be. In addition, in order to avoid interference and interference with radio wave users at adjacent stations and other nearby stations, the power emitted from the transmitting antenna 3 is kept to the minimum necessary limit, for example, the electric field strength at a distance of 30 meters from the transmitting antenna 3 is 10 microvolts. Adjust to about every meter.

When a route bus equipped with a bus stop name display device approaches a bus stop, radio waves emitted from the bus stop name transmitter enter the receiving unit 5 via the receiving antenna 4, and are roughly restored to code by the decoder 6. be done.

The CPU 7 searches the memory 8 for data on the bus stop name corresponding to this code. The data searched at this time is the data of the stop next to the stop of the code sent from the bus stop name transmitting device.

When the route bus moves away from the bus stop, the electric field strength becomes weaker, and there is no more information received from the receiver 5, the CPU 7
The next path stop name is displayed on the display 9 based on the data retrieved from the memory 8, and the tape recorder 10
The next path stop name is announced from the speaker 11.

[Effects of the Invention] As explained above, the present invention provides a stop name transmitting device for each bus stop, a stop name display device for each bus, and then displays the stop name of the scheduled stop through the driver's operation. By automatically informing passengers of the next pass stop name, passengers can be sure to get off at the stop they want to get off at, and the bus driver can This has the effect of ensuring the safe operation of route buses because drivers can be conscious of the prefecture when driving.
