Description

The invention relates to automation and remote control devices in railway transport and can be used in the systems of interval control of train movement.

The purpose of the invention is to increase reliability.

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

The device comprises a decoder 1 connected by exits with a locomotive traffic light 2 and a vigilance switch 3. Via switch 3, the control relays 4 are connected to the power source with contact 4.1 and the pulsation relay 5 with contacts 5.1-5.7. Front contacts 5.3-5.7 are connected between the outputs of the decoder 1 and the inputs of the locomotive traffic light 2. The front contact 4.1 is connected to the power supply circuit of the electro-pneumatic valve 6 of hitchhiking. Relay 5 pulsation performed

with two windings connected in opposite directions, in the circuit of one of which capacitor 7 is connected, and connected through front contact 5.1 parallel to the winding of control relay 4, and through rear contact 5.2 to the power supply.

The device works as follows.

If the vigilance switch 3 is in the position corresponding to the burning signal at the locomotive traffic light, for example green, as shown in FIG. 1, the key- {is supplied with a decoder to the corresponding input of the locomotive traffic light and through switch 3 to relay 4 and relay 5. In this case, relay 5 is constantly under current, not a pulsar, and therefore, the signal light of the locomotive traffic light does not flash.

When the signal is changed, the power supply to the first one disappears and power is supplied to the other output of the decoder. In this case, a relay circuit 4 and 5 is provided under the switch 3 to the first B1 | 1 input of the decoder. When power is lost from switch 3, relay 5 disappears. At the same time, its rear contact 5.2 is closed and it is again attracted, however, with a deceleration determined by the flow ratio, the counter current is turned on - HbJK windings of the relay 5 and the capacitor 7.
