Abstract
The invention discloses a vehicle alarm bell control circuit, a cab vehicle and a passenger car. The vehicle alarm bell control circuit comprises a silencing branch, an alarm lamp branch and an alarm bell branch, the silencing branch circuit, the alarm lamp branch circuit and the alarm bell branch circuit are connected in parallel between the first circuit end and the second circuit end; the first circuit end is used for receiving an alarm signal; the noise reduction branch comprises a driver noise reduction button and an alarm noise reduction relay, the driver noise reduction button is connected with a main coil of the alarm noise reductionrelay in series, and a self-holding normally open contact of the alarm noise reductionrelay is connected with the driver noise reduction button in parallel; the alarm lamp branch comprises a normally open contact of the alarm silencing relay and an alarm lamp, and the normally open contact of the alarm silencing relay is connected with the alarm lamp in series; the alarm bell branch comprises a normally-closed contact of the alarm silencing relay and an alarm bell, and the normally-closed contact of the alarm silencing relay and the alarm bell. By the adoption of the circuit, a driver can know the alarm information and cannot be affected by the noisy sound of the alarm bell.
Description
technical field [0001] The application relates to rail vehicle technology, in particular to a vehicle alarm bell control circuit, a cab car and a passenger car. Background technique [0002] During the operation of the vehicle, when the cab car receives the alarm signal transmitted by the locomotive, the alarm bell set in the cab will always alarm. The alarm bell will always be in working state unless the locomotive cancels the alarm signal. The alarm sound is noisy and lasts for a long time, which will affect the driver's work mood and directly affect the safety and reliability of the vehicle operation. [0003] Problems existing in the prior art: [0004] After the cab car received the alarm signal from the locomotive, the alarm bell kept alarming, which affected the driver's mood. Contents of the invention [0005] Embodiments of the present application provide a vehicle alarm bell control circuit, a cab car and a passenger car to solve the above technical problems. ...
