Abstract

The invention relates to a railway vehicle contact type obstacle detection circuit, which is characterized in that an emergency braking loop adopts a control logic that double train lines are connected in parallel with a backward relay, and ensures that an obstacle detection system can normally trigger the function of an emergency braking system in contact with an obstacle no matter the vehicle is in the working conditions of advancing and backing. And the emergency braking loop is controlled by the relay state of the obstacle detection system, emergency braking is triggered when the ODR loses power, the ODR state is controlled by the normally closed contact of the obstacle detection device, and fault guiding is safe. And power-off triggered braking is ensured. For a monitoring circuit, a normally open contact is adopted to provide input, when an obstacle is triggered, the normally open contact is closed, alarm information is provided, a subsequent alarm strategy is triggered, and reliability and usability are comprehensively considered in circuit design.

Description

technical field [0001] The invention relates to a rail vehicle obstacle detection circuit and belongs to the technical field of rail vehicle control circuits. Background technique [0002] As an important safety control system for unmanned driving, the contact obstacle system includes an obstacle detection control circuit and an obstacle detection and alarm strategy in its control strategy. According to the information sent back by the left and right detectors of the obstacle, it is determined whether a collision has occurred. [0003] After searching, it is found that the Chinese invention patent application CN103303338A discloses a rail vehicle contact obstacle detection device, which includes a detection beam, a toggle connecting plate, a travel switch and two elastic supports arranged symmetrically in a matching manner. The front end support arms of the support are fixedly connected together, the front end support arms of the elastic support are fixedly connected with a...
