Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a railway signal interlocking device having a timed unlocking operation indicator.

"Prior Art" The railway signal interlocking device works by linking a turning machine with a traffic light and a traffic light with a traffic light in order to ensure stable train operation on the premises. This interlocking device is centrally controlled by relay interlocking devices that use relays, and recently electronic interlocking devices that do not rely on relays have also been adopted.

For example, in the relay interlocking device, as illustrated in FIG. 2, the control panel has a display panel surface 10 modeling the premises, and the display panel surface 10 has an up line 11 and a down line 12 horizontally. As shown in parentheses between the premises lines, there are lines 1 to 4 on the premises, and a crossover 13 is provided at the entrance to the premises.

Rolling machine 2 at the place where each track and crossover 13 cross
1 _b, 21 _b, is provided with a 22 to 25, barb in the direction of the point lock device indicates the localization.

Traffic signals 1RA and 1RB are installed on the approach side of the up line 11, and traffic signals 8LC and 8LD are installed on the approach side of the down line 12. The end of the sign of the traffic signal is the section A on the premises,
It indicates that whether or not to enter the relevant section is displayed corresponding to B, C, and D. Further, traffic lights 2L to 5L indicating whether or not the vehicle can proceed in the down direction are installed.

In order to have a traffic light show a signal that directs the progress,
When the signal lever of the corresponding traffic signal is handled, the relay interlocking device automatically controls the switching machine in the section operated by the traffic signal, and also other traffic signals in the same direction and the traffic signal of the route to be the same arrival point. Is a stop signal and has not locked the route, and there are no other trains from the signal installation position to the arrival point. Show the signal that instructs the traffic light to proceed.

That is, the relay interlocking device has a safety function of safely checking various conditions.

One of the security functions of the relay interlocking device is an access lock. Second
In the figure, it is assumed that a signal for permitting the approach to the on-site traffic signal 1RB is currently displayed for the A train. The B train is waiting on the first line to make a turnaround. The operation of the A train was delayed for some reason, and I found that if I waited for this arrival and departed the B train, it would be delayed, so I decided to start the B train first.

In this case, after indicated current stop signal to the hall traffic 1RB back a signal lever which controls the hall traffic 1RB, point lock device 22 and 21 _b, 21 course _Lee from the one Line up downline 12 Will be opened.

At this time, when the train A is in a certain section close to the on-site traffic light 1RB, even if the driver checks the stop signal indication and applies the brakes, the driver may not stop by the on-site traffic light 1RB and may cross over. .

Such point lock unit 21 _b when 22 is dangerous because it will collide derailment or B train to be converted in or in opposite direction change.

Therefore, in order to prevent such a situation, the traffic signal 1R
If B is showing progress and A is approaching,
If the stop signal aspect to cancel the control of the hall traffic 1RB, ensuring the course of the up line 11 to line 2 of hall traffic 1RB indicates current progression, point lock unit 21 _b in the path, 22 is locked in a state where the route is secured, and unlocked after a time sufficient for the A train to stop so that the route of the B train can be opened.

This function is called an access lock, and unlocking after the sufficient time has elapsed is called timed unlocking.

In the conventional time-delay unlocking operation of the relay interlocking device, the timer switch 1 is operated as shown in FIG. 3, and the indicator light L is turned on to inform the operator that the time-delay unlocking operation is in progress. I was doing.

This situation is the same as in the case of the electronic interlocking machine in recent years, and in the present specification, various interlocking machines will be collectively referred to simply as interlocking machines.

[Problems to be solved by the invention] However, in such a display of the time-delay unlocking operation in the conventional interlocking device, it is possible to understand that the time-delay unlocking operation is being performed by the indicator light L, but the elapsed time Since it is not known at which stage of the process and the timing when the unlocking is completed is unknown, there is a problem that the next operation is delayed or the operation is complicated.

The present invention has been made in view of such a conventional problem, and the time unlocking operation in the interlocking device which solves the above problems by allowing the elapsed time of the time unlocking operation to be immediately understood. It is intended to provide an indicator.

[Means for Solving Problems] The gist of the present invention for achieving such an object is to provide a railway signal interlocking device having a time-delay unlocking operation indicator (20). The display device (20) includes a counter (23) that measures the elapsed time during the timed unlocking operation of the approach lock according to the timed operation condition, and a decoder (that converts the timed value of the counter (23) into a display value. 24) and a display device (20) for displaying the elapsed time by the output of the decoder (24).

"Action" Then, when the timed unlocking operation starts, the counter measures the elapsed time, the decoder converts the measured value into the displayed value as the elapsed time or the remaining time, and the indicator visually or ears it. The information can be displayed as recognizable information, and the operator can immediately understand the elapsed time and promptly perform appropriate operation.

[Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an embodiment of the present invention in which a timer switch 21 and a clock 22 to which the actual operating conditions are input are countered. 23, the counter 23 is connected to the decoder 24, and the decoder 24 is further connected to the display 25 to form the time delay unlocking operation display 20.

The counter 23 counts the clock signal of the clock 22 according to the timed unlocking operation start condition of the timer switch 21 and outputs the elapsed time. The decoder 24 is the counter 2
The elapsed time output of No. 3 is converted and the display value of the display 25 is output. The display unit 25 outputs the displayed value as a number, a sign, and a sound as an elapsed time display and a remaining time display.

Next, the operation will be described.

In FIG. 2, when the train is approaching and the signal indicating the progress is shown to the on-site traffic light 1RB, if the signal lever outside the drawing is returned and the control of the traffic light 1RB is cancelled, the time unlocking operation condition is satisfied. . At this time, the timer switch 21 shown in FIG. 1 is turned on, and the counter 23 starts from that point.
Starts timing.

The time count value counted by the counter 23 is input to the decoder 24, and the decoder 24 uses the time count value as elapsed time information in relation to the predetermined time set in advance.
Output to 5. According to the output of the decoder 24, the display 25 outputs a visual display or a display that can be confirmed by ear,
The operator of the relay interlocking device can immediately know the elapsed time of the timed unlocking operation.

When the output of the display unit 25 is a visual display, the display of the second number,
Alternatively, the time lapse is displayed by some kind of sign. When the output of the display device 25 is to be confirmed by ear, the time is uttered by voice.

When the remaining time is displayed on the display 25, a so-called countdown is performed, and the time when the display becomes 0 is the end of the elapsed time.

In the above embodiment, the relay interlocking device, which has been commonly used in the past, was illustrated, but it goes without saying that the same applies to a so-called electronic interlocking device that integrates logic to perform an interlocking operation.

[Effect of the device] According to the railway signal interlocking device according to the present invention, the operator of the interlocking device can immediately know the time elapsed until the time when the unlocking operation starts and the actual unlocking time can be realized. The operation of the machine will be simple and reliable, and quick and reliable operation will be possible.
