Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the content of a signal on an in-vehicle indicator light provided in a train, based on information obtained when the train passes over a grounding device provided on the ground. The present invention relates to an in-vehicle display device capable of displaying an image.

[0002]

2. Description of the Related Art Conventionally, when a train is controlled by an ATS (Automatic Train Stopping System) -P type, the speed is determined based on information obtained when the train passes through a ground rail provided on the ground. It is configured to generate a check pattern for checking. Then, the driver of the train drives the train to the traffic light indicating the stop indication within a range where the train does not exceed the generated check pattern.

Incidentally, as shown in the route map of FIG. 3 described in the section of the embodiment of the present invention, even if the track is curved and the train A enters the block 2T, the following When it is not possible to see the signal of the traffic signal (next signal) S3 in the block section, a relay signal S 'is installed, and the same signal content as the next signal S3 is displayed on the relay signal S'.

[0004]

However, in the above-mentioned conventional ATS-P type, when it is not possible to see the signal at a curve or the like, a signal for assisting the signal until the signal becomes visible. One or two or more relay signals have to be installed, which has the disadvantage of increasing equipment costs.

[0005] An ATC (Automatic Train Control System) exists as a system for displaying the present content of a traffic signal on a train (on a car) without requiring such a relay traffic signal. There is a drawback that the equipment becomes large because equipment for transmitting the ATC signal to the vehicle via the circuit is required. Further, the ATC can efficiently operate the train until the ATS-P type stops before the block section of the stop indication. On the other hand, in the ATC operation, the train speed is set for each track circuit. , The operation efficiency is reduced as compared with the ATS-P type.

Accordingly, an object of the present invention is to provide an in-vehicle display device capable of displaying the present contents of a traffic light even on a vehicle using the ATS-P type.

[0007]

In order to achieve the above object, an in-vehicle display device according to the present invention comprises: an in-vehicle indicator light provided in a train for displaying the present contents of a traffic light; Receiving means for receiving predetermined information from the ground child when passing through the provided ground child; extracting means for extracting the present information of the traffic light from the received information; Control means for controlling lighting of the in-vehicle indicator light based on the present information.

In order to achieve the above object, an in-vehicle display device according to the present invention includes an in-vehicle indicator light provided in a train for displaying the present contents of a traffic light, and a measuring means for measuring a traveling distance in the train. Receiving means for receiving predetermined information from the ground child when the train passes through a ground child provided on the ground, and a signal indicating a lighting range of the in-vehicle indicator light from the received information. Extraction means for extracting,
When a signal indicating the lighting range of the in-vehicle indicator light is extracted,

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration of an in-vehicle display device according to an embodiment, FIG. 2 is a flowchart showing its control operation, and FIG. 3 is a diagram of a route on which a train equipped with the in-vehicle display device travels. This is an example.

Since the in-vehicle display device 1 is constructed using an ATS-P type on-board device, first, an outline of ATS-P type train control will be described with reference to the route map of FIG.

A plurality (three in the illustrated example) of block sections (track circuits) 1 formed by dividing the rail r into a predetermined length.
Signals S1, S2 and S3 are provided at T, 2T and 3T, respectively. Then, each block section 1T, 2T,
In 3T, a plurality (3 in the illustrated example) is maintained at a predetermined interval.
(The ground children in the block section 3T are omitted. Hereinafter, the block sections 1T,
The explanation focuses on the 2T ground child. ) Are provided.

Each ground child a11, a12, a13, a21, a22,
a23 uses the information generated by the code processors (not shown) in the instrument boxes A2, A3 provided for the traffic signals S2, S3, respectively, for each of the ground children a11, a12, a13, a21, a3.
22 and a23 are respectively transmitted through relays (not shown). In addition, each equipment box A1, A2
, A3 are provided with signal control circuits (not shown), respectively, so that the lighting of each of the traffic lights S1, S2, S3 can be controlled.

[0013] In the route map of FIG.
There is another train (not shown) inside
The signal S3 for T is a stop signal (hereinafter referred to as "R signal"), the signal signal S2 for the block section 2T is a signal signal for caution (hereinafter referred to as "Y signal"), and a signal signal for the block section 1T. S1 is displayed on the progress announcement (hereinafter referred to as "G announcement").

The controller 2 of the in-vehicle display device 1 is configured to generate an inspection pattern for performing a speed inspection based on information taken through the vehicle upper arm 3. That is, the controller 2 is formed around the CPU, and generates a check pattern over a traveling distance from the installation position of the received ground child to the block section of the R display (3T in the example of FIG. 3). It is configured to be able to. Therefore, the driver of the train A can operate efficiently according to the generated check pattern before the travel distance of the own train obtained from the speed generator 4 reaches the block section indicated by R.

In FIG. 1 and FIG. 3, reference numeral 5 denotes an in-vehicle indicator light provided on a cab (not shown) of the train A. Like the traffic signals S1, S2, S3, R, Y, G Are configured to be displayed.

Each of the above ground children a11, a12, a13, a21, a
22 and a23, a predetermined ground child (in the example of FIG. 3, ground child a
12. Hereinafter, the predetermined ground child will be described as a12. )
In addition to the ATS-P type train control information,
The message frame transmitted from the vehicle includes data indicating that the in-vehicle indicator lamp 5 is turned on for a predetermined distance after the vehicle has passed a predetermined distance from the ground child a12.

As shown in FIG. 3, in the section where the in-vehicle indicator light 5 is lit, the driver of the train A cannot recognize the traffic signal (in the example of FIG. 3, the traffic signal S3 for the block section 3T). The data indicating this section and indicating this section is generated by a code processor provided in the equipment box A2 with the address of the ground child a12 added thereto.
Of course, since the data indicating this section is invariable, it can be fixedly stored in the ground child a12.

The lighting control operation of the in-vehicle indicator light 5 will be described below with reference to the flowchart of FIG. 2 and the route map of FIG.

Since the block 3T is blocked by a train (not shown), and the traffic light (next traffic light) S3 provided before the block 3T displays the R indication, the Y indication is displayed.

In FIG. 3, a range X indicated by hatching is a traveling range in which the driver of the train A cannot recognize the next traffic light S3. The range from a little before to almost the middle position of the ground children a21 and a22 in the block section 2T is a range where the traffic light S3 cannot be seen.

When the vehicle upper child 3 approaches the ground child a11 due to the running of the train A, predetermined information is received from the ground child a11 (Yes at Step 100; hereinafter, the steps are referred to as "S"). . Since the control signal of the in-vehicle indicator light 5 is not included in the message frame transmitted from the ground child a11, the normal processing of the ATS-P type, that is, the checking pattern from the ground child a11 to the next traffic light S3 Is generated and the train control is performed (No at S102).

When the train a advances further and reaches the ground child a12, a control signal of the in-vehicle indicator light 5 is received from the ground child a12 in addition to the ATS-P type information (S10).
2 affirmation). The present information (Y present information) of the current traffic signal S2 is fetched from the received signal, and the contents of the present (R present) of the next traffic signal S3 are generated from the fetched present information. Is performed (S104, S106). In addition, by making the information sent from the ground child a12 include the indication information of the next traffic signal S3, the generation of the indication content of the next traffic signal S3 can be simplified.

The control signal of the in-vehicle indicator light 5 includes
Since the information of the section where the in-vehicle indicator light 5 is to be displayed is included from the installation position of 12, the traveling distance from the ground child a12 obtained from the speed generator 4 reaches the section (X) to be displayed. (S108 affirmative), the R indication is displayed on the in-vehicle indicator light 5 (S110).

The displayed R indication is continued until the train A passes the section (X) (Yes at S112, S1
14). Therefore, the driver of the train A
In the range (X) where is not recognized, the vehicle can be driven based on the present state of the in-vehicle indicator light 5. In addition, when the next traffic light S3 becomes visible, the in-vehicle indicator light 5 is turned off, so that the driver does not see the two types of traffic lights in one block section, and the train operation is safe. Can be achieved.

In the above-described example, an example is shown in which the traffic light provided along the track and the in-vehicle indicator light are used together. May be displayed. In this case, each of the ground terminals transmits an in-vehicle display control signal in addition to the ATS-P type information.
