ともに、その間はATC機能が損われるという問
題があつた。 If there is a no-signal section in the ATC ground equipment due to construction, malfunction, etc., the ATC failure detection circuit in the onboard equipment detects the no-signal condition, and this causes an emergency brake to be applied. Then, by setting the emergency operation switch, the emergency braking condition that occurs due to the no-signal condition is suppressed, allowing the train to run in the no-signal section. However, the conventional ATC failure detection circuit maintains the failure detection function even if the emergency operation switch is set, and operates the holding relay when a failure is detected. The ATC failure detection circuit operates and is held while driving in a no-signal area, so if you cancel emergency operation after passing through a no-signal area, the emergency braking condition of the ATC failure detection circuit is restored and the emergency brake I get stiff. Therefore, conventionally, once you pass through a no-signal section,
There was a problem that normal operation could not be resumed even in a signalized (normal) section and the train had to run in emergency operation, and the ATC function was impaired during that time.
そこで、この発明はATC地上設備の無信号区

機能するようにしたATC装置用車上装置を提供
することを目的とする。 Therefore, this invention was developed to set the emergency operation switch and pass through the no-signal section of the ATC ground equipment.
To provide an on-vehicle device for an ATC device that enables normal operation to be resumed when an emergency operation switch is reset and allows ATC to function normally thereafter.

ーの接点でそれぞれ構成されている。 Next, an embodiment of the present invention will be described based on the drawings. In the figure, A is an ATC failure detection circuit. Since recent ATC onboard equipment is composed of three systems, the ATC failure detection circuit A is configured to detect failures in each system: failure detection circuit 1 for system 1, failure detection circuit 2 for system 2, and failure detection circuit 3 for system 2. It consists of a system failure detection circuit 3 and a non-appearance detection circuit 4 for detecting no current in the track circuit or non-appearance of a signal (including failures of wayside and onboard elements). The system failure detection circuits 1 to 3 and the non-indication detection circuit 4 are each constituted by contacts of an indicator relay (not shown).

る。 Further, in the figure, reference numerals 5 to 8 are holding relays for each of the failure detection circuits 1 to 4, which are set by the detection output of each failure detection circuit. The non-display detection circuit 4 outputs an output to operate the holding relay 8 when all the display relays are restored. This setting of holding relay 8 provides an emergency braking condition.

加圧線が切り離される。 10 is an emergency operation switch.
When turned ON, the emergency operation relay 11 operates. In this invention, the contacts of this emergency operation relay, 11a,
11b is inserted into the pressure line l1 of the ATC failure detection circuit A and the reset circuit l2 of the ATC failure holding relay. As a result, emergency operation switch 1
If the ATC fault holding relays 5 to 8 are in operation when 0 is turned on, they are all reset by the contact 11b and the emergency brake condition disappears.
Further, the pressurizing wires of each of the failure detection circuits 1 to 4 are separated by the contact 11a.

が可能である。 With the above configuration, when the train approaches a no-signal section on the ground during normal operation and the no-signal detection circuit 4 detects no signal, the holding relay 8 operates;
Emergency brake is applied. If the vehicle wishes to travel in a no-signal section, the emergency operation switch 10 is turned on, the emergency operation relay 11 is operated, and the holding relay 8 is reset by the contact 11b. The emergency operation switch releases the emergency brake, allowing the train to run. Then, the pressurized line of the failure detection circuit A is disconnected by the contacts 11a and 11b of the emergency operation relay, and all the holding relays 5 to 8 are reset, so even if the train runs in a no-signal section, These failure detection circuits and holding relays do not operate. Then, when the train leaves the no-signal section and enters the normal section, when the emergency operation switch 10 is turned off, the pressure line of the failure detection circuit A is reconnected, and the holding relay 5
-8 are placed in a settable state. Therefore, normal operation with a normal ATC failure detection function is possible from now on.

運転を維持することができる。 Since the contact 11b on the reset circuit l2 side of the emergency operation relay is provided in parallel with the manual reset switch 9, for example, if one of the on-board devices fails, the system failure detection circuit 1, 2 or 3
is activated and the holding relay 5, 6, or 7 falls, and if the fault in that system is corrected, the holding relay is manually restored by pressing down the reset switch 9, and the triple system is activated. Highly reliable operation can be maintained.

る。 As described above, according to the present invention, the contact circuit of the emergency operation switch is inserted into the pressure line of the ATC failure detection circuit and the reset circuit of the failure hold relay,
When the emergency operation switch is operated, the contact circuit disconnects the pressure line and resets the fault hold relay, so when the emergency operation switch is set, a new ATC is automatically activated.
Since the ATC failure detection function is not accepted and the failure holding relay is reset, if the emergency operation switch is reset after passing through the no-signal section due to emergency operation, the ATC failure detection function will be automatically restored to the initial state. and normal operation can be resumed.
