Abstract

The invention relates to railway automation, in particular to an automatic locomotive signaling system with control of the driver’s vigilance. The purpose of the invention is to increase reliability. The device contains a code decoder 1 associated with a locomotive speed tester 2, a speed control relay 4, a watch hand relay connected to a power source through a contact in the watch handle, a mode switch, the rear contact 24 of which is connected in series with contact 8 of an additional handle vigilance and rear contact of the auxiliary button, in parallel with which the front contact 17 of the green fire alarm relay is on. Parallel to the white contact 24, the front contact 25 is connected, which is connected between the front contact of the green fire signal relay and the serially connected front contacts of the sig-. yellow and red-yellow relay lights. The supply circuits of the electro-pneumatic braking valve 3 are connected in series with the front contacts 27.7 and 9 of the auxiliary button of the watchman control. 1 il. .a (L

Description

.and.

The invention relates to railway automation, in particular to an automatic locomotive alarm system with a driver control vigilance field.

The purpose of the invention is reliability.

The drawing shows a schematic diagram of the device for monitoring driver vigilance.

The device contains a decoder 1 code, locomotive speed meter 2 with contacts 2.1-2.3., Electro-pneumatic valve 3, speed control relay 4 with contact 4.1, block 5 of the watchout relay with contacts 5.1 and 5.2, contacts 6 and 7 of the upper alert handle, pins 8 and 9 of the lower auxiliary alert handler, relay 10 of the alert handler with contacts 10.1 and 10.2, contacts of the signal relays of red and yellow fire 11 and 12, yellow fire 13 and 14, green fire 15-17 (the relays are not shown), capacitors 18 and 19, resistors 20 and 21, diode 22, pins 23-25 of the mode switch c and pins 26 and 27 of the auxiliary button.

The device works as follows.

Confirmation of vigilance with the use of two handles of vigilance involves pressing the upper handle with contacts 6 and 7 to stand at any locomotive traffic light, and the lower additional handle with contacts 8 and 9 sits only at yellow fire and white fire with a rare confirmation of vigilance in areas not equipped with autolock.

If a yellow and a red light is on at the locomotive traffic lights, periodic vigilance checks are carried out continuously to ensure that the speed does not exceed the permissible level. Speed control relay 4 receives only intermittent power from a capacitor through a circuit through contacts 13 and 14 of the signal relays, contact 5.2 of the watchdog relay, resistor 21 and contact 2.1 of the speedometer. The capacitor is charged through the front contact 10.1 of the watchout relay, diode 22 and resistor 20. The watchdog relay relay is energized through contact 6 of the top watchman handle

In case of white light at the locomotive traffic light, the 4 speed controls also receive periodic power through the upper watchfulness knob (pin 6) (capacitor 18 is discharged across the circuit: resistor 2t, pin 5.2 of the alert unit and pin 13 of the signal relay).

In case of a yellow light on the locomotive traffic light, the relay 10 of the alert handler receives power through the contacts 12 and 1A of the alarm relay, contact 23 of the button, contact 8 of the lower additional watchfulness handle. With white fire with a rare test of alertness, the power supply of the relay 10 of the alert handle is received through the front contact 17 of the signal relay,

T-pin 23 button and rear contact 8 of the alert handler.
