DEVICE FOR CONTROL OF THE LED TRAFFIC LIGHT FUNCTIONING Russian patent published in 2018 - IPC B61L5/18 

FIELD: traffic control systems.

SUBSTANCE: invention relates to the field of railway automatics and telemechanics for controlling the LED traffic light. Device contains a recorder and a series-connected current source, a front contact of the alarm relay and a group of connected LEDs, the rear contact of the alarm relay, a source of constant voltage of the reverse polarity and a resistor connected between the point of connection of the negative pole of the current source with the positive pole of the voltage source of the reverse polarity, the negative pole of which through the rear contact of the signal relay is connected to the connection point of the anode of a group of connected LEDs, which are the traffic light emitter, with the front contact of the signal relay. And the point of connection of the resistor with the positive pole of the source of direct voltage of reverse polarity is connected to the control input of the recorder, the common input of which is connected to the cathode of a group of connected LEDs.

EFFECT: increase in the reliability of the monitoring device is achieved.
