BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 shows a functional circuit configuration thereof, wherein 1 is an on-vehicle transmission control unit installed in a train to be controlled, 2 is installed near a running path R of the train, and It is a terrestrial transmission control unit that performs mutual wireless transmission with the upper transmission control unit 1.
[0019]
The on-vehicle transmission control unit 1 holds the preset vehicle length and knitting growth of this train as data, and stores the data held when the train passes near the ground transmission control unit 2 on the ground transmission control unit 2. And receives the data of the installation point distance from the terrestrial transmission control unit 2.
[0020]
The terrestrial transmission control unit 2 holds a preset installation point distance from the terrestrial transmission control unit 2 to the stop position as data, and stores the data at the time of passing through the train. And the vehicle length and knitting growth of the train are received from the on-vehicle transmission control unit 1.
[0021]
However, the terrestrial transmission control unit 2 is connected to the terrestrial data processing unit 4, and the terrestrial data processing unit 4 receives a stop position target indicating lamp 5 according to the vehicle length and knitting growth data of the passing train received from the terrestrial transmission control unit 2. To control lighting. In this case, if there are a plurality of stop position target indicator lights 5, an appropriate one corresponding to the vehicle length and knitting growth data of the passing train received from the above-mentioned ground transmission control unit 2 is judged from the plurality of them. Lighting control is performed only on the object to be turned on.
[0022]
On the other hand, on the train side, the on-vehicle transmission control unit 1 operates under the control of the on-vehicle data processing unit 3. The rotation detection unit 6, the display unit 7, the audio output unit 8, and the external device connection unit 9 are connected, and their operation is controlled.
[0023]
The axle rotation detector 6 detects the number of revolutions of the axle of the train, and the detection signal is sent to the on-vehicle data processor 3.
The on-vehicle data processing unit 3 includes data of the installation point distance indicating the distance to the stop position target obtained from the ground transmission control unit 2 by the on-vehicle transmission control unit 1, a detection signal of the axle rotation detection unit 6, and a preset value. The distance to the stop position target is calculated by comparing the calculated travel distance of the train using the calculated wheel diameter, and the calculated distance to the stop position target is displayed on the display unit 7.
[0024]
When the train stops, the on-board data processing unit 3 recognizes that the train is in a stopped state based on the detection signal of the axle rotation detection unit 6, and determines the distance at that time, that is, the moving amount of the train, The vehicle length and the distance between the stop position targets suitable for knitting growth are compared with each other to determine whether or not the stop position at that time is appropriate. The determination result is displayed on the display unit 7. On the other hand, the judgment result is output as voice by the voice output unit 8. The on-board data processing unit 3 can transmit and receive data to and from external devices other than the terrestrial transmission control unit 2 by the external device connection unit 9. It is also possible to output to the external device information of the determination result indicating whether or not the stop position output from the on-board data processing unit 3 when the train stops is appropriate. .
[0025]
In the above configuration, the ground transmission control unit 2 installed at a point in the vicinity of the traveling path separated by a preset distance from the stop position target, the vehicle mounted on the train by passing the train When the data of the installation point distance is transmitted to the upper transmission control unit 1 and the data of the train length and knitting growth of the train is received from the on-vehicle transmission control unit 1, the received data is immediately transmitted to the ground data processing unit 4. Transferred to
[0026]
If there is only one stop position target indicator light 5 according to the vehicle length and knitting growth data of the passing train from the ground transmission control unit 2, the ground data processing unit 4 sets the stop position target indicator light 5 to: When there are a plurality of stop position target indicator lights 5, only those appropriate for the vehicle length and knitting growth data of the passing train received from the ground transmission control unit 2 are judged from among them, and lighting control is performed. In addition, guidance assistance is provided when the train stops.
[0027]
On the train side, the on-board data processing unit 3 calculates the moving amount of the train using the detection signal of the axle rotation detecting unit 6 and a preset wheel diameter. The distance to the stop position target is constantly calculated by comparing the data with the installation point distance indicating the distance to the stop position target obtained from the ground transmission control unit 2 via the transmission control unit 1, and the calculated stop is calculated. The distance to the position target is specifically displayed on the display unit 7, and the driver assists the driver in guiding the stop position together with the stop position target indicator 5.
[0028]
When the operator stops the train, the on-board data processing unit 3 recognizes that the train is stopped based on the detection signal from the axle rotation detection unit 6, and determines the distance at that time, that is, the above-mentioned ground transmission control. Comparing the travel distance of the train after passing through the section 2 with the installation point distance received from the ground transmission control section 2, that is, the distance between the train length and the stop position target suitable for knitting growth, In this case, while it is determined whether or not the stop position at that time is appropriate and the determination result is displayed and output on the display unit 7, the determination result is output as a predetermined audio signal by the audio output unit 8 in a loud voice. Further, information on the determination result may be output from the external device connection unit 9 to an external device (not shown) so as to utilize the information regarding the train stop state.
[0029]
By performing such an operation, the train operator stops the train while receiving guidance support by the lighting display of the stop position target indicator light 5 and the distance display on the display unit 7, and the position at which the train actually stopped is determined. Whether it is appropriate or not can be confirmed by the display contents on the display unit 7 and the audio signal on the audio output unit 8.
[0030]
Therefore, the position to be stopped can be quickly and accurately guided to the train operator in a very easy-to-understand state, and the operator's attention is greatly reduced compared to the conventional system, and the psychological burden due to tension is reduced. By alleviating this, the fatigue of the operator is directly linked to danger, which can also contribute to improvement of safety.
