PNEUMOELECTRIC CONVERTER FOR BRAKING CONTROL SYSTEM OF LIGHT RAIL VEHICLE Russian patent published in 2024 - IPC B61H11/00 B61H13/34 B60T13/26 

FIELD: railway transport.

SUBSTANCE: invention relates to the braking system of a light rail vehicle. The pneumoelectric converter of the braking control system of a light rail vehicle comprises a pressure alarm and a pressure sensor configured to connect with their pneumatic inputs to a pneumatic brake line, an electronic control unit, an electromagnetic starter relay and an electromagnetic shutdown relay, wherein the starter electromagnetic relay is configured to be powered by electric current through electrical communication lines E1 and E2, the electronic control unit and pressure sensor are configured to be powered by electric current through electrical communication lines E3 and E4, the pressure sensor is configured to convert pressure in the pneumatic brake line into an analogue electrical signal and transmit the signal via communication line E5 to the input of the electronic control unit, one output of which is connected to the E6 communication line, and the other output is connected by the E7 communication line to the electromagnetic shutdown relay.

EFFECT: ability to control the electromechanical brakes of a towed light rail vehicle based on a signal about a change in pressure in the brake line of the towing locomotive, which increases the safety of rolling stock during towing and shunting operations.
