Description

TECHNICAL FIELD The present invention relates to a method for displaying a rolling-stock set configuration for displaying a rolling-stock set in a driver's cab and a conductor's cab.

[Conventional technology]

In general, the stop position of the train differs depending on the number of connected vehicles, so that the crew member needs to recognize the number of connected vehicles, and in the past, the crew member recognized it by memorizing it.

[Problems to be solved by the invention]

However, when connecting or disconnecting at a station on the way, the number of connections will change from that point, and the crew must remember the new number of connections each time, and if you have to pay attention to that, from the viewpoint of safe operation. Is not preferable. For this reason, it may be possible to automatically recognize the train formation and display the car numbers from the first car to the last car in accordance with the train condition. Since it is necessary to reverse the display direction in the case of, and when the number of connected vehicles changes, there is no suitable display method for realizing this.

[Means for solving problems]

In order to solve such a drawback, the present invention provides a display suitable for the traveling direction based on the recognition result obtained by automatic composition recognition and the condition of the front / rear switch.

[Action]

 A display suitable for the traveling direction is displayed.

〔Example〕

FIG. 1 is a diagram showing a train configuration, and shows one edition component. In the figure, 1 ₁ is the leading vehicle, 1 ₂ to 1 _n-1 are intermediate vehicles, 1 _n
Is a tail vehicle. Leading vehicle 1 and tail car 1 to _n before and after switching device 5, display 6, setter 7, it is provided converter 8, only transducer 8 is provided in the intermediate car 1 ₂ to 1 _n-1 . FIG. 2 shows a state in which vehicles of such a formation are connected to form three formations.

The display unit 6 and the setting unit 7 are adapted to receive signals from the front / rear switching unit and perform necessary display and setting as a device placed in a driver's cab or a conductor's cab. The converter 8 is adapted to generate a signal for sending the state of each car number to the service line.

In a device constituted as above, of the transducer 8 at power provided to 1 _n top car 1 ₁ or tail wheel, a knitting structure to adjacent vehicles are connected from either defined A recognition signal for recognition is sent out. At this time, the passage of the signal line to the succeeding vehicle after the adjacent vehicle is cut off. The vehicle that has received the recognition signal sends a new recognition signal obtained by adding 1 to its own vehicle number after connecting the signal line lead in the vehicle. The adjacent vehicle behind this vehicle receives the new recognition signal and performs the same processing as described above. In this way, the recognition signal obtained by sequentially adding 1 to the vehicle number is received by the next adjacent vehicle. At this time, if it is a division of the formation, a signal indicating the division of the formation is also transmitted. It is becoming like this. When the signals are sequentially transmitted in this manner, all the vehicle names can be recognized in due course. Using the train formation configuration result recognized in this way, data to be displayed on the display 6 and the setting device 7 is created as follows.

The recognition of the formation composition described above is generated at the time of setting the vehicle number.
The first knitting allocation data shown in FIG. 3 (a) and FIG. 3 (b)
And the second formation allocation data shown in FIG. In FIGS. 3 (a) and 3 (b), L is the length of a bit, and in this example, 4 bits are taken. A is the last vehicle number address of the first formation, B is the last vehicle number address of the second formation, C is the last vehicle number address of the third formation, and D is the last vehicle number address of all the formations. In addition, the car number address is one less than the number of the car number, and it takes a value from zero to FH.

The setting device and display device that received the formation assignment data assign the car number and formation division to the formation data 1 to 16 (8 bytes make up 1 byte, consisting of 16 bytes in total) in the buffer area of the device. .

The composition data 1 to 16 correspond to the 7-segment numeric display for displaying the composition of each vehicle for each vehicle, are stored in BCD code, and respectively correspond to the display, as shown in FIG. .

The composition data 1 to 16 correspond to a 7-segment numeral display for displaying composition composition for each vehicle, and are stored in BCD code. Also, the top two bits are used to display the dot points representing the formation division.

Here, the operation when the Tc 'side (local side, that is, the side far from Tokyo station) is displayed as Car 1 is shown in Figs. 5 and 6.
It will be described with reference to the drawings.

In FIG. 5 (a), the last vehicle number address of the first formation is stored in “A” of the memory, the last vehicle number address of the second formation is stored in “B”, and in FIG. 5 (b). The last vehicle number address of the third formation is stored in “C”, and the last vehicle number address of all formations is stored in “D”. Based on these data, among the knitting data shown in FIG. 5 (c), the data corresponding to the last car of the knitting is identified by the upper two bits as the knitting of the knitting. I am trying.

BCD codes 1, 2, 3, ... Are sequentially allocated from the formation data 1 as shown in steps 100 to 104, and the allocation work is repeated for the final vehicle number data + 1 times. Where step 102
Is calculated by BCD code. Then step 10
As shown in 5,106, after adding a dot point to the last car number, as shown in step 107, the address where the formation data 1 of the buffer area is entered is the last car number address of the first formation, that is, FIG. "A" shown in a) is added and a dot point is added to the knitting data at that address. Note that step 106 is a subroutine.

Therefore, as shown in step 108, it is judged whether or not the last vehicle number address of the second formation is zero, and if it is zero, the allocation is ended, and if it is not zero, the formation data is shown in steps 109 and 110. Dot points are added to the address obtained by adding the last vehicle number address of the 2nd formation to the address of 1. Here, step 110 is a subroutine.

Next, as shown in step 111, it is determined whether or not the last vehicle number address of the third formation is zero, and if it is zero, the allocation is terminated, and if it is not zero, as shown in steps 112 and 113,
Dot points are added to the formation data obtained by adding the final vehicle number address of the third formation to the formation data 1 to display the allocation.

By performing such a process, the indicator 6 shown in FIG. 1 displays the first car as the first car and the last car as the 16th car as shown in FIG. It is displayed as shown in Fig. 8. Here, the numbers "5", "10", "1"
The dot points added to "6" represent the division of the composition. Also, in Fig. 7 and 8, up to car No. 16 is displayed, but when it is shorter than 16 cars, unstructured part is not displayed.

Next, the operation when the traveling direction changes will be described. At this time, the front / rear switch 5 shown in FIG. 1 is switched, so that the program shown in FIG. 9 is carried from this condition. Since the Tc side closer to Tokyo Station runs with the leading car running, the following process is performed and the display direction of the train set shown in FIGS. 7 and 8 is reversed. That is, the place where the number "1" is displayed becomes "16", the place where the number "16" is displayed becomes "1", and it is displayed that the No. 16 car is running. That is, the fact that the traveling direction of the train has changed is detected by the switching operation of the front / rear switch, and the display positions on the display 6 of the leading car and the trailing car are changed to a state adapted to the traveling direction.

As shown in steps 200 to 206, the data obtained by adding 1 to the last vehicle number is converted into a BCD code and assigned to the knitting data 1, and then the value obtained by sequentially reducing the BCD code by 1 is used as knitting data. Allocate and repeat until the value becomes "1". Then, as shown in steps 205 and 206, a dot point is added to the first car.

Next, at step 207, the first from the last vehicle number address
It is determined whether the value obtained by subtracting the last car number address of the formation is zero. If it is zero, the allocation is completed.
As shown in 8,209, a dot point is added to the knitting data of the address obtained by adding (final car number address-final car number address of the first train-1) to the address of the knitting data 1. Similarly, as shown in steps 210 to 212, if the value obtained by subtracting the last car number address of the second train set from the last car number address is zero, the allocation is ended, and if it is not zero, the train data 1
A dot point is added to the organization data of an address obtained by adding (final vehicle number address-final vehicle number address of the second formation-1) to the address of. Steps 213-215 are also steps
In the operations of 210 to 212, the same processing is performed except that the second composition data is changed to the third composition data.

〔The invention's effect〕

As described above, the present invention automatically recognizes the train set, and the result of the recognition and the condition of the front / rear switching switch cause the leading car in the traveling direction to be displayed as the leading car of the display device. The crew has the effect of being able to immediately recognize the actual train formation and concentrate on safe operation.
