Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a broadcasting device for providing a guide broadcast to train passengers.

[Conventional technology]

In general, a train is provided with a broadcast device for performing a guide broadcast to passengers, and performs a guide broadcast of a destination, a stop station, an arrival time, and the like.

[Problems to be solved by the invention]

Such a conventional broadcasting device has no problem in the case of fixed formation, but in the case of a train which changes connection by connecting and disconnecting to the final destination, correct broadcasting is required unless the train composition is always recognized. Therefore, if the train is frequently changed, the conductor's attention is directed to the guide broadcast, which is not preferable from the viewpoint of safe operation. In addition, in the holiday season and the like, the burden on the conductor of the conductor when operating such that the number of connected vehicles is changed between holidays and weekdays becomes even greater.

[Means for solving the problem]

In order to solve such a drawback, the present invention automatically recognizes and displays a train set, and reduces the labor burden on a conductor.

[Action]

The train formation is automatically recognized, and a broadcast for each formation is performed based on the recognition result. By selecting an arbitrary vehicle, a broadcast for only the selected vehicle is performed.

〔Example〕

FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, 1 is a train recognizing device for recognizing train trains, 11 to 26 are connected states based on the formation results, that is, the connected car numbers are individually displayed in the cabin, and the decimal point display unit is made to emit light. , Display switches for selecting the broadcast line of each car, 31 to 46 are single selection switches for individually selecting the broadcast line of each car, 2 to 4 are formation selection switches for selecting the broadcast line for each formation, and 5 is a collective switch. Broadcast switch, 6
Is a switch for a green car, 7 is a switch for a non-smoking car, 8 is an amplifier, 9 is a selection circuit, and 51 to 66 are speakers for broadcasting provided in each car.

When the formation selection switches 2 to 4 are pressed, the selection circuit 9 selects the broadcasting line for the car number of the selected formation in conjunction with the recognition result of the formation recognition device 1, and selects the single selection switches 31 to 46. When one of the switches is pressed, the broadcast line of the vehicle number corresponding to the switch pressed is selected.

The selection circuit 9 is composed of a known circuit, for example, as shown in FIG. In the figure, reference numeral 90 denotes a train formation recognition result recognized by the formation recognition device 1 and operation outputs of formation selection switches 2 to 4, a collective broadcast switch 5, a green car switch 6, and a non-smoking car switch 7. A selection circuit control unit 101 for outputting a broadcast selection signal for selecting speakers 51 to 66 provided for each vehicle to a broadcast selection line 91;
To 116, converters for outputting broadcast switching signals 121 to 136 in response to detection of a predetermined broadcast selection signal from the broadcast selection line 91;
Broadcast switches 1 to 156 individually control whether or not to supply the broadcast signals output from the amplifier 8 to the broadcast line 92 to the speakers 51 to 66 according to the broadcast switching signals 121 to 136. Each of the converters 101 to 116 and the broadcast switchers 141 to 156 are disposed separately for each vehicle corresponding to each of the speakers 51 to 66, and each of the converters 101 to 116 is connected to the broadcast selection line 91. The broadcast switches 141 to 156 are commonly connected to the broadcast line 92.

Now, when the single switch 32 (see FIG. 2) corresponding to the second car among the single switches 31 to 46 is operated, the selection circuit control unit 90 detects this and receives the input from the formation recognizing device 1 in advance. Based on the recognition result of the current train set, the second car is selected as a broadcast target, and a broadcast selection signal addressed to the corresponding converter 102 is output to the broadcast selection circuit 91. Converter 102 detects a broadcast selection signal and outputs a broadcast switching signal 122 when the broadcast selection signal is addressed to itself. In response, the broadcast switch 142 supplies the broadcast signal output to the broadcast line 92 to the speaker 52, and the broadcast signal is output only from the speaker 52 of the second car corresponding to the single switch 32.

The same applies to the case where a switch for selecting a vehicle to be broadcast, such as the formation selection switches 2 to 4, the batch broadcast switch 5, the green car switch 6, and the non-smoking car switch 7, is operated in the same manner as described above. One or more vehicles to be broadcast are selected based on the train organization recognition result input from 1 and a broadcast selection signal is output to the corresponding converters 101 to 116 via the broadcast selection line 91. As a result, a broadcast switching signal is output from each of the converters to be broadcast, and the corresponding broadcast switch operates to operate the broadcast line 92.
The above broadcast signal is output from the speaker of the vehicle to be broadcast.

The selection circuit control unit 90 holds the type information of each vehicle, for example, a green car, a non-smoking car, a formation, etc., as a train formation recognition result output from the formation recognition device 1 in advance. The target vehicle is selected according to the operation of the various switches to be selected.

FIG. 2 shows an example of the arrangement of the display units 11 to 26, the single selection switches 31 to 46, the organization selection switches 2 to 4, the batch broadcast switch 5, the green car switch 6, and the non-smoking car switch 7.
These parts are attached to a part of the setting device placed in the conductor compartment.

In the device configured as described above, when the power is turned on or the formation is changed, the formation recognizing device 1 recognizes the train formation, supplies the recognition result to the selection circuit 9, and displays the display units 11 to The recognition result is displayed on 26. The example shown in FIG. 2 is a 16-car train consisting of the first to the 16th cars. The divisions of the formations are displayed on the decimal display sections 15a and 20a of the indicators 15 and 20. Cars 1 to 5 represent the first train, Cars 6 to 10 represent the second train, and Cars 11 to 16 represent the third train. In the example of FIG. 2, since the rear end is an example of the 16th car, the number display 26 is displayed, but if the rear end is, for example, the 11th car, the displays 22 to 26 are not displayed. I'm sorry.

Here, when it is desired to carry out the guide broadcast only to the first train, when the formation selection switch 2 for the first train is pressed, the selection circuit 9 selects the broadcasting line of the first to fifth cars and the amplifier 8
Is connected to the first to fifth cars, so that the guide broadcast can be performed only to the first train. Similarly, vehicles of the second and third formations or green cars,
If a switch such as a non-smoking car is selected, a guide broadcast can be made only to the corresponding vehicle. By pressing the batch broadcast switch 5, the broadcast can be broadcast to all vehicles.

When the third train is released at a station in the middle of the train of the train shown in FIG. 2, the train recognition device 1 recognizes this fact and displays the display 21.
Turn off ~ 26. For this reason, the conductor can know the composition at that time only by looking at the display, and can reduce the labor for the guide broadcast.

FIG. 3 and FIG. 4 are diagrams for explaining the operation of the knitting recognition device 1 for automatically performing knitting recognition. In FIG. 3, 1 and 2 are trains, respectively, leading cars 1a, 2a,
It consists of intermediate wheels 1b, 2b and tail wheels 1c, 2c. Here, the vehicle with the driver is defined as the leading vehicle, and the vehicle with the conductor conducting the driving operation is defined as the tail car. The first vehicle 1a is defined as the first vehicle, and the last vehicle 2c is defined as the last vehicle.

Front and rear switches D1 to D4, display DP, setting devices S1 to S4 for setting various conditions, and converters H1, H3, H4, H6 for transmitting and receiving data are provided for the leading vehicles 1a, 2a and the trailing vehicles 1c, 2c. Are provided, and converters H2, H5 are provided in the intermediate wheels 1b, 2b. Top car 1a, 2
The setting devices S1, S3, the display device DP, and the converters H1, H4 provided in a are set as Tc 'vehicles, that is, vehicles on the Tokyo side.

The leading cars 1a and 2a and the trailing cars 1c and 2c have inverters (not shown). In the case of one train, the leading cars 1a and 2a that have been set as Tc 'cars give priority to output. When no power is output from this vehicle, rear wheels 1c, 2
c outputs. In the case of FIG. 3, since there are two trains, the leading car 1a gives priority to the output of the inverter, and if this output is not performed, the trailing car 2c performs output.

FIG. 3 (a) shows a state before the power is turned on, and the power supply U0 and the signal path S are respectively formed with a serial connection.

When the power is turned on in the train configured as described above, the setting device S1 operates an inverter (not shown) based on the conditions of the Tc 'side and the front-rear switching device D1, and supplies power to the power supply path U0. Then, based on the conditions of the front / rear switching devices D1 to D4, as shown in FIG.
The setting devices S2 and S3 close the passage. After that, the setting device S1
Since the first allocation start data (for example, address 10H, data 40H) is sent out from the condition on the c 'side, the setting unit H1
H6 receive this data. At this time, each setting unit H1 ~ H6
Is configured to transmit a non-verification answer-back signal indicating non-verification when it cannot be verified that the data is the first allocation data. The drawing is opened as shown in FIG. 3 (c).

After that, the setting unit S1 sends cueing data (for example, address 10H, data 00H) for cueing the knitting, so that the converter H1 that has received this data has received the collated answer record indicating that the signal has been received. After transmitting the signal, the signal path to the intermediate vehicle 1b, which is the rear vehicle, is closed as shown in FIG. 3 (d). Then, second allocation data (for example, address 10H, data 10H) is transmitted.

As a result, the second allocation data is received by the setting unit H2,
From this, a verified answerback signal is transmitted. Then, the setting unit H2 closes the connection as shown in FIG. 3 (e) and sends out third allocation data (for example, address 10H, data 11H) obtained by counting and adding the vehicle number 1. The third allocation data is received by the converter H3. After transmitting the verified answerbook signal, the converter H3 closes the passage as shown in FIG. Fourth allocation data added (for example, address 10H, data 12H)
Is sent.

The allocation data shown in FIG. 4 is received by the setting unit H4, and after the collated answer-back signal is sent out therefrom, the connection is closed as shown in FIG. 3 (g). Here, since the setting unit H4 is set on the Tc 'side, it recognizes the change of the formation, adds one count to the contents of the formation, and adds fifth count of the car number to the fifth allocation data (for example, address 10H). ,
Data 23H) is transmitted.

Hereinafter, in a similar procedure, the vehicle number recognition is performed sequentially following the sequence up to the setter H6. And setting device S4 is Tc
It recognizes that the knitting is the last from the conditions of the side and the condition of the front / rear switch D4, and assigns the allocation end data (for example, address 10H,
Data 80H), the setting unit S1 receives the allocation end data and receives the composition allocation data (for example, addresses 16H,
Data 5052H).

A series of data transmission is completed by this operation. However, when the power is turned on, the vehicle number is automatically recognized sequentially from the leading vehicle to the trailing vehicle, so that the leading vehicle 1 is automatically recognized. By displaying the results recognized so far in ₁ and the last vehicle ₁₆ on the display DP, the number of connections and the composition are displayed.

Next, the operation at the time of connection and disconnection will be described. First, as shown in FIG. 4, an operation when the first train 1 and the second train 2 are connected will be described. Before the connection shown in FIG. 4 (a), the setting devices S1 to S4 are front-rear switching devices D1 to D4.
The opening is opened from the condition of D4, and T
The inverters I1 and I3 are operating from the condition on the c 'side.

When this train is connected as shown in FIG. 4 (b),
The forward / reverse switch D2 connected to the setting device S2 is switched to the middle position by the managing staff, and it is detected that there is no power supply from the train 2, and the setting device S2 is switched as shown in FIG. 4 (c). Close the drawing. The set switch S3 is connected to the front / rear switch D3 and is set to the middle position by the crew. When the power supply from the train 1 is detected, the inverter I3 is opened.
Is controlled to be turned off. The setting device S4 controls the inverter I4 from off to on since the power supply is lost due to passing through.

The setting unit S3 is used when power is supplied from the train 1.
Inverter off data (for example, address 12H, data 80H) for turning off the inverter I4 is sent to S4. The setter S4 receiving this data controls the inverter to be turned off. After confirming that the power supply from the setter S4 side has been stopped, the setter S3 closes the passage as shown in FIG. 4 (d). By performing the above control, the train I, the train I, and the train I are controlled by the setter S1.
Power is supplied to the train 2. After that, the setting device S3 displays allocation data (for example, an address) indicating that the composition has changed.
10H, data 40H).

Next, the operation at the time of disconnection will be described. Before the disconnection, as shown in FIG. 4 (e), the inverter I1 controlled by the setting device S1 supplies power to the trains 1 and 2, and the setting device S1
2, S3 is closed when receiving the condition of the middle position of the front / rear selectors D2, D3.

In order to perform disconnection, the front / rear switch D2 connected to the setting device S2 is switched from the middle position to the front or rear position,
As a result, the setting device S2 opens the train and the train 1
And the train 2 is electrically disconnected as shown in FIG. 4 (f). As a result, the setter S2 sends out the allocation start data (for example, address 10H, data 40H) to the train 1.

At the time when the opening is established by the above-mentioned setting device S2, power is not supplied to the train 2, but at this time, the train 2 operates such that the inverter I4 controlled by the setting device S4 operates. Power is supplied from the inverter I4.

Next, when the front / rear switch D3 connected to the setting device S3 is switched from the middle position to the front or rear position, the setting device S3 is turned to the fourth position.
As shown in FIG. 7 (g), the connection is opened and the allocation start data (for example, the address 10H and the data 40H) is connected for the connection. Thereafter, the train 1 and the train 2 are divided into two as shown in FIG. 4 (h).

Thus, when a connection or disconnection is made,
Since the allocation data is transmitted, the change in the formation is recognized, and the new car number is recognized. If this recognition result is displayed on the display, the driver or conductor can identify the new number of connected vehicles in the formation. it can.

〔The invention's effect〕

As described above, the present invention automatically recognizes and displays a train organization, and can broadcast using the recognition result, thereby reducing the effort and attention of a conductor for guidance broadcasting. This has the effect that the labor and attention can be redirected for safe operation.
