Description

[Detailed explanation of the invention] This invention is used for Shinkansen trains, etc., and is an ATC system that types information such as signal type, train speed, etc., which changes from moment to moment, on printing paper as they change.
This invention relates to a recorder for an on-board device.

Conventional ATC on-board device recorders print the train number and point number (points are set approximately every 3 Ian) along with external conditions such as signal type every time these external conditions change. In order to record more accurately, it is desired to also record time and distance.

However, if the number of printing digits is increased in order to print these, the recording device becomes larger and the width of the printing paper also becomes larger.

An object of the present invention is to provide a recorder for an ATC on-board device that can record time and distance without increasing the number of printed digits.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example of a printing paper 1 printed by the ATC on-vehicle recorder according to the present invention.

The first to third digits from the left are the train number and time, the fourth digit is the signal type, the fifth digit is the train speed, the sixth digit is the brake type, the seventh digit is the reception level, the eighth digit is the logic mechanism failure, and the 9th digit is signal equipment failure, 10th digit is backup, 11th digit is unit failure, 12th digit is equipment failure, 13th digit is switch operation, 14th...
The 16 digits display the point number and distance, respectively.

The train number is printed in the first to third digits 2 5 seconds after the power is turned on and every 1000 seconds, and all of the digits of Shisen are spaces.

In Figure 1, the train number is 860.

Each time external conditions such as signal type or point number change, a time expressed in three-digit seconds is printed in the first to third digits 2.

In the 14th to 16th digits 3, point numbers are printed when the train passes through points provided about every three lines on the railway track.

At that time, the time is printed in the first to third digits 2, the signal type is printed in the fourth digit, and all other digits are spaces.

In Figure 1, point number 001 changes to 360 at 241 seconds.
A point number 002 is printed on each second.

Then, each time external conditions such as signal type change, a distance represented by a three-digit number is printed in the 14th to 16th digits 3.

For this distance, the point where the point number is printed is Qm, and one unit of approximately 46 m, that is, 0001.

Reading the print in Figure 1, the train with train number 860 is
1 second later signal E1 vehicle speed F, brake C1 distance 000, 50 seconds later the signal changes to D at distance 000, 63 seconds later the brake changes to P at distance 000, 92 seconds later distance 00.
1, the vehicle speed changes to E.

Note that : is a symbol indicating normality. FIG. 2 shows the time train number selection circuit.

The oscillation circuit 4 sends IHz pulses to the time counting circuit 57, and the time counting circuit 5 repeatedly counts from 000 to 999 seconds.

The train number setting device 6 is for setting a train number.

When the power is turned on, the time counting circuit 5 has been reset and its output is 000 seconds, so the 1000 second relay 7 is set to 1 by this 000 second output.
Operates for seconds.

By closing the lifting contacts R, -1 of the 1000 second relay 7, the first switching circuit 8 prevents the output of the time counting circuit 5 from being transmitted to the first decoder 9.

On the other hand, since the lifting contact R1-3 of the 1000 second relay 7 is also closed, the train number setting device 6 falls to the zero unit, thereby sending the train number signal set by the train number setting device 6 to the type selection circuit 10 of the printer. It will be done.

The printed character selection circuit 10 selects the first to third digit printed characters as the numbers of the train number.

Five seconds after the power is turned on, another relay (not shown) operates to start the oscillation circuit 4 and generate a print command signal, which causes only the first to third digit printing mechanism parts to operate. , the train number is printed as shown in the first column of FIG.

When the 1000 second relay 7 operates for 1 second and then falls, the first switching circuit 8 transmits the output of the time counting circuit 5 to the first decoder 9, and the first decoder 9 transmits the output of the time counting circuit 5 to the first decoder 9. The output of the counting circuit 5 is sent to the type selection circuit 10 as a time signal.

By opening the lifting contact R0-3, the train number setting device 6 no longer outputs the train number signal.

When external conditions such as signal type change, the type selection circuit 10 selects the first to third digit type according to the time signal at that time, and prints all digits according to the print command signal for all digits generated due to the change in external conditions. The printing mechanism operates, and as shown in the second column of FIG. 1, the time indicated in three-digit seconds is printed in the first to third digits 2.

When the time counting circuit 5 counts 999 seconds and then automatically resets to 000 seconds, the 1000 second relay 7 operates and the train number signal is transmitted from the train number setting device 6 to the print selection circuit as described above. Sent to 10.

On the other hand, the pole contact R1-1 changes from open to closed, and the falling contact R1-2
At the moment when switches from close to open, both contacts R1
-1 and R1-2 are both open, so the inputs of the NAND circuit N1 become 1 and 1, and the output becomes 0, which is converted to 1 by the impark circuit l.

Since the output 1 of the inverter circuit 1 returns to 0 once the contacts R1-1 and R1-2 are switched, a narrow pulse is generated, and this pulse is sent to the printer as the train number print command signal S. Sent.

The NAND circuit N1 and the inverter circuit 1 form a train number print command signal generation circuit 11.

In response to the train number print command signal S1, only the first to third digit printing mechanism operates, and the train number is printed as shown in the 15th column of FIG.

Similarly, the train number is printed every 1000 seconds.

FIG. 3 shows a distance point number selection circuit.

The point relay 12 operates all the time and drops when the train passes the point.

Therefore, the lifting contacts R2-1°R2-3 are always closed,
Since the falling contacts R, -2, and R2-4 are open, the second switching circuit 13 transmits the output of the distance counting circuit 14 to the second decoder 15, and the third switching circuit 16 transmits the output of the distance counting circuit 14 to the point number counting circuit 1.
7 is not transmitted to the third decoder 18.

The distance condition generation circuit 19 generates approximately 46 meters due to the rotation of the train's wheels.
A distance condition pulse is generated every m, and this distance condition pulse is counted by a distance counting circuit 14.

The output of the distance counting circuit 14 is connected to the second switching circuit 13 and the second
The signal is sent via the decoder 15 to the character selection circuit 20 as a distance signal.

When external conditions such as signal type change, the type selection circuit 20 selects the 14th to 16th digit type according to the distance signal at that time, and prints all digits according to the print command signal for all digits generated due to the change in external conditions. The printing mechanism part operates, and the distance represented by a three-digit number is printed in the 14th to 16th digits 3, as shown in the second column and below in FIG.

When the train passes the point, the point relay 12 falls, so the lifting contacts R2-1 and R2-3 open, and the falling contact R2
-2, R2-4 closes, the second switching circuit 1
3 prevents the output of the distance counting circuit 14 from being transmitted to the second decoder 15, and the third switching circuit 16 transmits the output of the point number counting circuit 17 to the third decoder 18.

At the same time, the output of the NAND circuit N3 changes from O to 1, and the point number counting circuit 17 counts 1.

Further, the output of the NAND circuit N2 changes from 1 to 0, thereby the distance counting circuit 14 is reset, and the point number print command signal generation circuit 21 generates a point number print command signal S2 and sends it to the printer. 1st to 4th digits and 14th to 1st
Operates only the 6-digit printing mechanism.

The output of the third decoder 18 (1 point number counting circuit 17 is sent as a point number signal to the type selection circuit 20, and the type selection circuit 20 selects the 14th to 16th digit type depending on the point number signal. As shown in the 10th column or the 13th column of FIG. 1, a point number represented by a three-digit number is printed in the 14th to 16th digits 3.

Note that NAND circuit N2. N3 is contact R2-3 or R2-4
This is to prevent the negative effects of chattering.

In addition, in the illustrated embodiment, the 1000 seconds that the time counting circuit 5 repeatedly counts is the fixed time of the present invention,
The 1000 second relay 7 corresponds to the time relay of the present invention.

As explained above, according to the present invention, the train number is printed in the train number and time digits by the train number print command signal, and the time is printed by the all digit print command signal or the point number print command signal. The number of digits to be printed can be changed by setting the number of digits to be printed and the distance by using the print command signal for all digits. You can record time and distance without increasing the time.
