Abstract

PURPOSE:To provide a device for preventing erroneous vehicle departure in a vehicle base inexpensively and surely. CONSTITUTION:An erroneous departure prevention transmitter 7 for transmitting an ATC signal of limiting speed 10km/h when a shunting signal 6 is displaying stoppage, and transmitting a non-installation switching signal for bringing an onboard ATC device into an inoperative state when the signal 6 is displaying advance, is connected to a loop coil 2 for detecting a train in a section immediately before the signal 6 in a storage track. Accordingly, if a vehicle erroneously departs when the signal 6 is displaying stoppage, it is forcibly stopped because of absence of a signal inside, and if the vehicle departs at the time of an advance signal the ATC device is in an inoperative state and allows the vehicle to travel. When the signal 6 is displaying stoppage and the vehicle is waiting in a storage track, traveling of the vehicle for manual brake inspection and vehicle position adjustment is allowed, and in the case where the vehicle is accelerated from rearward it is forcibly decelerated immediately before the signal 6 to decrease over-traveling distance. Only new installation of a transmitter 7 is required so that the device can be provided inexpensively.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an erroneous departure preventing device when a vehicle leaves a vehicle depot.

[0002]

2. Description of the Related Art At a vehicle depot, cost problems and
Most of them do not have a ground ATC device because there is not enough space in the vehicle base to secure a sufficient overrun distance required when installing a TC (automatic train control) device. Currently, the driving of vehicles at the time of entry and exit from the depot is performed by visual inspection of the interchange signal.

In this case, for example, when a vehicle parked on the detention line immediately before the turnout exits, the route is opened at the turnout, and the indication of the interchange traffic light becomes the progress (G) indication. The driver visually confirms that the vehicle should be delivered. However, in the current situation where the interchange signal is delivered by visual inspection, many vehicles are lined up and stopped at the depot, so when leaving when the surroundings are still dark, such as in the early morning of winter, the wrong detention line is used. There is a danger that, when the vehicle is in a vehicle, the surroundings are dark and the interchange signal of the detention line of the vehicle in which the vehicle is aboard is illusion that it is a progress indicator.

In order to prevent such a danger, there is conventionally a vehicle depot provided with an erroneous departure prevention device as described below. That is, a short loop coil is laid directly under the replacement traffic signal on the detention line where the unloading vehicle is stopped, and when the replacement traffic signal is stopped (R), the loop coil is stopped by the ATC.
It is configured to transmit a signal and not to transmit a signal when the interchange traffic light indicates progress. Here, the on-board ATC device is A
When a TC non-equipment signal is received, it is automatically switched to a non-operating state and its state is stored, and when an ATC signal is received, it is automatically switched to an operating state and its state is stored. When the vehicle with the ATC facility enters the vehicle depot without the ATC facility, an ATC non-equipment signal is transmitted to the upper side of the vehicle at the base entrance to automatically deactivate the on-board ATC device. It is possible to drive inside the depot.

In such a conventional apparatus, when the vehicle leaving the vehicle departs even though the interchange signal signal shows the stop and the ATC signal of the stop flowing to the loop coil is received, the on-board ATC apparatus automatically switches to the operating state. The brake operates to forcibly stop the vehicle and prevent accidental departure. Incidentally, since the signal is not transmitted to the loop coil when the interchange signal is showing the progress, the on-board ATC device can be driven without any trouble in the inoperative state.

[0006]

However, in the conventional device, since a short loop coil is laid directly under the interchange signal, it is effective when the vehicle stopped immediately before the interchange signal is erroneously started, but from the rear side. For vehicles that are accelerating, the vehicle will reach a considerable speed immediately under the traffic signal (generally up to 25 km / h in a vehicle depot section without ATC), so a long overrun distance is required. There is a problem in terms of base space because it is necessary to provide sufficient inward sections after the exchange signal. Also, within the detention line, we would like to test the manual brake by loosening the brake even when the interchange signal stops showing for the delivery check. At this time, if the stop signal is received from the loop coil, the on-board ATC device is activated and the automatic braking by the ATC device is activated, so that the manual braking test cannot be performed. Further, there is a problem that even if an attempt is made to correct the stop position of the vehicle within the detention line, the correction cannot be made if the stop signal is transmitted.

An object of the present invention is to provide a vehicle erroneous departure prevention device in a vehicle depot that solves the above problems.

[0008]

Therefore, when an ATC non-equipment signal is received, it is automatically switched to a non-operating state and its state is stored, and when an ATC signal is received, it is automatically switched to an operating state and its state is stored. In a vehicle erroneous departure prevention device that manages the entry / exit of a vehicle equipped with an on-board ATC device by means of an interchange signal and at the time of vehicle exit in a vehicle depot where the ground ATC device is not installed, a branching device in front of the exit vehicle A transmission that transmits a low-speed ATC signal to the existing vehicle detection circuit in the outer section immediately before the nearest interchange signal and transmits an ATC non-equipment signal when the signal indicates progress. It is configured by providing means.

[0009]

In such a configuration, when the interchange signal is in the stop indication, the transmitting means transmits a low-speed ATC signal to the outer section immediately before the interchange signal so that the vehicle can travel at a low speed. It is possible to perform a braking test and position correction of a manual brake. Further, for a vehicle accelerating from behind, the vehicle can be decelerated in the section immediately before the interchange signal by transmitting the low-speed ATC signal, and there is no signal in the inward section that has entered after passing the interchange signal. Therefore, emergency braking is applied and stopped by the on-board ATC device that is switched to the operating state by the low-speed ATC signal, so that the overrun distance can be shortened.

Further, when the interchange signal is showing progress, the transmitting means transmits an ATC non-equipment signal to the outer section immediately before the interchange signal, so that the low speed ATC is indicated by the stop indication on the vehicle side. Even if the ATC device is once activated by the signal, the ATC device is deactivated again, so that it is possible to drive the section inside the interchange signal at a predetermined speed in the vehicle depot.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1 showing the circuit configuration of the present embodiment, a train detection circuit is installed in each section of the track 1 in the depot to obtain position information of the vehicle necessary for managing entry / exit of the vehicle. ing. The train detection (TD) circuit includes a loop coil (TD loop) 2 laid in each section, and a verification signal transmitter 3 that transmits a verification signal to the loop coil 2.
And a train detection signal receiver (TD receiver) 4 that receives a train detection signal from the vehicle via the loop coil 2.

In this embodiment, when the traveling direction of the vehicle leaving the vehicle is set to the direction of arrow A in FIG. 1, the switching signal 6 closest to the branching device 5 in front of the vehicle leaving the vehicle passing through the track 1 is displayed. A low speed (eg 10km / h) ATC when the exchange signal 6 is stopped (R) in the train detection circuit in the immediately preceding outer section.
An erroneous departure prevention transmitter 7 is provided as a transmission means for transmitting a signal (10 signals) and transmitting an ATC non-equipment switching signal (X signal) when the progress (G) is indicated. The outer section up to the front side of the interchange signal 6 with respect to the traveling direction of the leaving vehicle is the detention line. In addition, a section ahead of the interchange signal 6 is called an inner section.

Next, the operation of the apparatus of this embodiment will be described with reference to FIGS. First, the case where the interchange signal 6 in front of the branching device 5 is in progress indication will be described with reference to FIG.
When the turn signal of the front track 1 is set by the branching device 5 and the interchange signal 6 is showing the progress, the transmitter 7 causes the loop coil 2 to deactivate the on-board ATC device in the section immediately before. The X signal which is the equipment switching signal is transmitted. The other sections are no signal (N) sections with no signal. Then, the vehicle 8 waiting on the detention line immediately in front of the interchange signal 6 receives the non-equipment switching signal at the time of warehousing and automatically stores the ATC device on the vehicle in a non-operating state. At the time of departure, the ATC device on the vehicle can travel without operating, and as shown in the figure, the vehicle can be traveled at an increased speed up to a speed of 25 km / h or less and can start. When the vehicle accelerates from the rear as shown in the figure
You can keep the speed of 25km / h or less and proceed as it is.

Next, referring to FIG. 3, a case where the interchange signal device 6 is stopped and the vehicle 8 is waiting in the section immediately before the interchange signal device 6 will be described. In this case, 10 signals are transmitted from the transmitter 7 to the loop coil 2 immediately before that as an ATC signal for limiting the traveling speed to 10 km / h. Also,
The other sections are non-signal (N) sections with no signal. For this reason, the vehicle 8 waiting on the detention line immediately before the interchange signal 6 automatically receives the 10 signal when the vehicle 8 enters this section and the ATC device on the vehicle automatically installs the equipment, that is, operates. Memorize this. Then, if the vehicle 8 accidentally departs despite the stop indication, as shown in the figure, the vehicle 8 can travel at a speed of 10 km / h or less, but enters the no signal (N) section immediately after the interchange signal 6. At the time, ATC on the car
Emergency braking is applied by the operation of the onboard ATC device because the device is already in operation in the previous section,
The vehicle 8 is forcibly stopped. Therefore, even if the vehicle 8 starts erroneously, the vehicle 8 can be stopped immediately and derailment or the like at the branching device 5 can be prevented. In addition, even when the replacement traffic signal 6 is stopped, in the section immediately before the replacement traffic signal 6.
Since the vehicle can travel at a speed of 10 km / h or less, the position of the vehicle 8 can be corrected and the manual brake can be inspected during standby.

On the other hand, when the route is set and the interchange signal 6 is changed from the stop indication to the progress indication while the vehicle 8 is on standby, the transmitter 7 is a non-equipment switching signal X instead of the 10 signal.
Send a signal. When the vehicle 8 on standby receives this X signal, the ATC device is automatically deactivated. As a result, the vehicle 8 can travel at a speed of 25 km / h or less as in the case of FIG. 1, and can start according to the progress indication.

Next, a case where the vehicle is accelerating from the rear when the interchange signal 6 is stopped will be described with reference to FIG. Also in this case, 10 signals are transmitted as the ATC signal in the section immediately before the exchange traffic signal 6, and the other sections are non-signal (N) sections without a signal. The vehicle 8 accelerating from the rear can travel at 25 km / h or less before entering the section immediately before the interchange signal 6, as shown in the figure. Then, when entering the section just before the interchange signal 6, the 10 signal is received and the brake of the ATC device is activated to forcibly decelerate to 10 km / h or less. Furthermore, when the vehicle passes the interchange signal 6 as it is and enters the next section, this section is a no-signal (N) section, and the on-board ATC device has already been switched to the operating state by the reception of the 10 signal. ATC
The emergency braking of the device is applied, and the vehicle 8 is forcibly stopped. In this way, even if the vehicle accelerates from the rear, it is forcibly decelerated to 10 km / h or less in the section immediately before the interchange traffic light 6, so even if the location of the interchange traffic light 6 is mistakenly passed, it will pass more than before. Since the speed is low, the overrun distance that needs to be provided immediately after the interchange signal 6 is short, which is advantageous in securing a base space as compared with the conventional case.

According to such a configuration, the existing circuit can be used, and it is not necessary to provide new equipment such as a loop coil exclusively for preventing an incorrect start at the vehicle base as in the conventional case, and the upper side of the vehicle also has the existing ATC. The device can be used as it is and no equipment is required to prevent accidental departure. It is also possible to check the manual brakes and adjust the vehicle position before leaving the warehouse. Further, there are many advantages such as a short overrun distance and an advantage in securing a base space.

In this embodiment, a loop coil type train detection circuit is laid as an example, but the invention is also applicable to a depot where a track circuit type train detection circuit is used. It is possible to apply the device.

[0019]

As described above, according to the present invention, when the interchange traffic signal indicates the stop, the ATC is displayed in the section immediately before the stop signal.
As a signal, a low speed signal for limiting the traveling speed to a low speed is transmitted, and when the interchange signal is showing progress, a non-equipment switching signal for automatically deactivating the on-board ATC device is transmitted. 、 Even if the replacement traffic signal starts erroneously despite the stop sign, when the vehicle passes the replacement traffic signal and enters the next section, emergency braking is activated by the on-board ATC device to prevent a vehicle derailment accident. It can be prevented. In addition, even if the vehicle is accelerating from the rear, the vehicle is forcibly decelerated before the interchange signal, so the overrun distance can be shortened and the base space can be secured more advantageously than before. Furthermore, since the vehicle can travel at a low speed even during standby, manual brake inspection and vehicle position adjustment are possible.
