Train automatic braking control circuit based on bogie instability detection device

Abstract

The invention provides a train automatic braking control circuit based on a bogie instability detection device. The braking control circuit in the driver's cab controls the action of the destabilizing braking trigger relay and the on-board equipment braking command relay; when the bogie destabilization detection device in a carriage detects abnormal vibration of the train, the destabilization of the bogie The output relay acts to trigger the bogie instability action relay, the bogie instability action relay is energized, the normally closed point of the bogie instability action relay in the control circuit is disconnected, the instability braking trigger relay is de-energized, and the on-board The equipment brake command relay is energized, and the train applies the brake. The circuit of the invention overcomes the defects of only relying on the train network system for braking control, being interfered and disconnected.

Description

technical field [0001] The invention relates to the field of circuit design, in particular to a train automatic braking control circuit based on a bogie instability detection device. Background technique [0002] At present, the operating environment of EMUs is complex and changeable, and the bogie instability detection system is one of the key systems to ensure the safe operation of trains. [0003] Under the current technical conditions, after the train bogie instability device detects abnormal vibration, it outputs a fault signal to the train network system, and automatically limits the speed through the network system. [0004] As a key system to ensure the safe operation of trains, it only relies on the train network system for braking control, and there is a risk of interference and disconnection. Therefore, it may affect the train braking, resulting in serpentine movement of the bogie, which will bring a negative impact on the safe operation of the train. come at ris...
