Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for automatically broadcasting information inside a vehicle of a mass transportation system such as a railway or a mole rail.

As is well known, in-train information is broadcast by the conductor using a microphone using a broadcasting device.

Alternatively, predetermined information may be broadcast using a recorder, such as in a one-man bus.

However, if the conductor is eliminated and the train is operated only by a driver, or if the train is operated unmanned, there is no one to make guidance announcements, so it is impossible to make announcements by humans.

Furthermore, when broadcasting using a recorder, it is difficult to perform broadcasts that are appropriate for various situations.

Therefore, the present invention has been made in order to eliminate the above-mentioned inconveniences and provide sufficient service to passengers when realizing single-crew operation or unmanned operation, and can be realized with a relatively simple device configuration. This is what I am trying to do.

In order to achieve the above object, the automatic broadcasting device for a vehicle of the present invention transmits guidance broadcast information using a transmitting device installed along the track, receives this information using a receiving device equipped on the vehicle, This is intended to be broadcast as an in-car broadcast.

At this time, by adding a device that detects the timing of reception and the timing of the end of broadcasting, the receiving device and the broadcasting device can be turned on and off, and the reliability of the device can be increased.

Furthermore, by adding a device that obtains the number of the train to be received as code information and determines whether or not to broadcast based on the determination, reliable broadcasting becomes possible.

In addition, the received information is stored in a recorder or the like and is reproduced and broadcast when necessary.

The present invention will be explained below with reference to Examples.

FIG. 1 shows an example of an automatic broadcasting device for vehicles according to the present invention.

Transmitting devices 2.degree. 3 installed along the orbit transmit audio information based on command information from the guidance broadcast command device 4.

The guidance broadcast command device 4 knows that the train has entered the receivable section, the destination of the train, and the type of service such as express or local, and then commands voice information for guidance regarding the next station.

The guidance broadcast command device 4 can identify the train and know its location via a conventionally used CTC device (centralized signal control device) or the like.

The transmitted audio information is received by receiving devices 5 and 6 inside the vehicle.

The received audio information is broadcast by the broadcasting device 7 to the inside of the car through the speaker 8.

By providing the audio information receiving device in the vehicle in this manner, any information commanded by the guidance broadcast command device can be broadcast into the vehicle.

However, in the example shown in Figure 1, there is no way to know when a broadcast will be transmitted, so the receiving device and broadcasting device must be kept on standby at all times. A decrease occurs.

Another embodiment of the present invention designed to eliminate this inconvenience is shown in FIG.

Here, another receiving device 9-10 and a device on/off determining device 11 are added to the example shown in FIG.

That is, a transmitter or a resonant ground element is installed at the starting point of the information transmission process, and the receivers 9 and 10 detect this.

Upon this detection, the equipment on/off determination device 11 turns on the receiver 6 and the broadcasting device 7, making them effective.

When broadcast information is transmitted, it is broadcast as described in the example of FIG.

For this example, an example of a time chart of equipment and signals along the orbit is shown in Fig. 3.

A transmitting antenna 2 is installed along the track 13 before and after the platform 120.

Transmission to trains is possible in the section where antenna 2 is installed.

Here, A is a train passage detection signal, B is processing of the guidance broadcast command device, C is a transmission and reception signal, D is a ground element detection signal, E is a receiver state, and F is a broadcasting device state.

Based on the train passage detection signal A-1 from the train passage detection device 15-a, the guidance broadcast command device performs processing to edit the content to be broadcast as a broadcast upon arrival at the station.B-L
When the transmitting devices 2 and 3 transmit the edited information C-1, on the other hand, when the receiving devices 9 and 10 detect the beacon 14-a in the vehicle, the detection signal D-1 causes the equipment on/off determination device 11 to , the receiver 6 is in the on state and the EL broadcasting device 1 is in the on state F-1.

Therefore, the transmitted information C-1 is broadcast inside the vehicle.

Further, the station departure broadcast is also broadcast as C-2 based on the detection signal 15-b in the same manner as the arrival broadcast.

A beacon 14-b is installed at a position where the train exits the section where transmission is possible.

When the train detects this, the equipment on/off determination device 11 turns off the receiver 6 and the broadcasting device 7 based on the detection signal D-2 E-1, F-1. By making full use of the broadcasting equipment, the lifespan of the equipment will be extended and reliable reception will be possible.

In a transmitting device, the section where a train can receive signals varies depending on the frequency and strength of the radio waves and the length of the transmitting antenna.

Therefore, it is conceivable that many trains may receive a signal transmitted from one transmitting device.

Distinguishing between up and down trains can be achieved by changing the transmission frequency.

However, it is difficult, for example, to transmit signals by changing the frequency for each upstream train.

FIG. 4 shows another embodiment of the present invention designed to eliminate such inconveniences.

That is, the guidance broadcast command device 4 creates information specifying the train to be received before the audio information to be broadcast,
It is transmitted by transmitting devices 2 and 3.

An information determining device 16 is provided which determines received train designation information and determines whether subsequently transmitted audio information is to be broadcast as an in-train broadcast.

That is, the information determination device 16 compares the number set in advance for the train and the received train-designated number, and if they match, it is assumed that the train is the designated train and the received audio information is broadcast in the train, and if they do not match, the received audio information is broadcast in the train. If so, it is determined that the train is not designated, and the received audio information is invalidated and no broadcast is made.

A time chart for this example will be explained with reference to FIG.

Here, G is the received signal of the receiver 6, H is the train designation information extracted from the received signal, ■ is the output signal of the information determination device 16 based on the train designation information, and J is the on-off state of the broadcasting device 7. shows.

G-1 is a signal indicating the start of one transmission, and based on this, the information determining device 16 determines the timing for receiving the train designation information G-2 to be received next.

The information determination device 16 extracts the train designation information H-1 and compares it with the number stored therein.

In the example shown in FIG. 5, the train number of the user is 1101.

Since H-1 is 1011, this transmission information is determined to have been sent to another train, and the information determination device 16 outputs nothing.

Therefore, after that, the received information does not reach the broadcasting device, and the audio information G-3 is not broadcast into the vehicle.

The same process is performed in the next transmission, and this time the train designation information H-1' is 1101, which matches the own train number, so the information determination device 16 outputs a signal of 11.

As a result, the receiving device and the broadcasting device are connected and the broadcasting device is turned on, Jl, and thus the received information G-3' is broadcasted into the vehicle.

The I-1 signal indicates the end of the audio signal G-3/. G-4'
The information determination device 16 is turned off by this signal.

As a result, broadcasting was interrupted. In this way, information can be transmitted and broadcast only to the target train.

Note that the voice information and data information such as train designation information may be transmitted on the same carrier wave or on separate carrier waves.

. In the case of separate carrier waves, waves 2 and 3 must be transmitted by a receiving device that can receive both waves.

Furthermore, by creating a code for train designation information that all trains receive, there are advantages such as being able to use it for simultaneous broadcasting in emergencies.

In the embodiments described above, the received information is immediately broadcast as is, but if the reception period is short, long broadcasts cannot be made, and broadcasting outside the reception period is impossible.

FIG. 6 shows another embodiment of the present invention designed to eliminate such inconveniences.

This is the example shown in FIG. 1, with a recorder 18 for storing received information, receiving devices 9 and 10 for obtaining timing signals for starting recording and broadcasting, and a control device 17 for controlling the equipment at the above-mentioned timing. be.

In other words, information to be broadcast is transmitted in bulk, and when received, it is recorded and reproduced at the required timing to be broadcast.

Regarding this example, the relationship between equipment along the track and signal timing will be explained with reference to FIG.

In the example shown in FIG. 7, information is transmitted around the station.

This is because trains stop at stations, so there is a lot of transmission time.

Here, K is a train passing detection signal, L is processing of the guide broadcast command device M is a transmission and reception signal, N is a beacon detection signal, O is a recording state of the recorder, and P is a reproduction state.

-1 to the detection signal from the train passing detection device 15-a, the guide broadcast command device 4 edits information such as station departure broadcast and station arrival broadcast for the train, and transmits it by L-1 and transmitting devices 2 and 3. ~1~M4, where M-1
is a station departure broadcast, M-2 is a signal indicating the end, M-3 is a station arrival broadcast, and M-4 is a signal indicating the end of transmission.

If you want to broadcast more information, use Ml, M-
You can repeat it in the second form.

In the vehicle, when the ground element 14-d is detected by the receiving devices 9 and 10, the control device 17 activates the recorder 1 based on the detection signal N-2.
The end of the 0-1o recording is controlled by the control device 17 using the M-4 signal indicating the end of transmission.

The recorded received information is reproduced and broadcast by detection by ground transducers 14-C and 14-e.

First, when the train leaves the station, it passes through the ground transceiver 14-e.

When this is detected by the receivers 9 and 10, the control device 17 uses this detection signal N-3 to start playback on the recorder 18 P-2, uses an endless tape in the recorder 18, and adjusts the length of the tape to an appropriate length. If you do this, even if you play back the station departure broadcast M-1, the station departure broadcast M-1 will be broadcast by broadcasting device 7. You can also leave it there.

In response to the reproduction signal Q-4 of the M-2 signal indicating the end of the station departure broadcast, the control device 17 stops the reproduction of the recorder 18.

After that, when the train approaches the station, it passes the ground transceiver 14-C.

In response to this detection signal N-1, the control device 17 starts the playback of the recorder 18 again P-1゜This causes the station arrival broadcast M
The control device 17 stops the reproduction of the recorder 18 by the Q-2 signal, which is the reproduction of the M-4 signal in which -1 is broadcast through the broadcasting device 7 and indicates the end of the Q-1 degree transmission.

In addition, in the case of a recorder that performs winding back here, Q.
-2 signal to perform winding.

In this way, the information to be broadcast can be received all at once and broadcast to the inside of the car at the necessary time.

Note that with this method, only information received at the previous station can be broadcast.

However, by transmitting and receiving information specifying whether information should be recorded or broadcast as is, direct broadcasting within the transmission/reception period is easily possible.

As explained above, according to the present invention, an automatic broadcasting device for a vehicle having the following effects can be realized.

(1) Since this is an automatic broadcasting device that does not require an operator in the vehicle, the number of crew members in the vehicle can be reduced or the vehicle can be unmanned.

(2) Since the guidance broadcast command device on the ground can determine the broadcast content by grasping the situation of the entire route and broadcast it on the vehicle, passengers can be provided with appropriate service according to the situation.

(3) Even when there are many trains, by receiving train designation information, it is possible to broadcast only to a specific train.

- (4) Even if there is only a small part of the transmitting device, broadcasting can be performed from a desired point by recording.
