Train automatic braking control circuit based on bogie unstability detecting devices

Abstract

The invention provides a train automatic braking control circuit based on bogie unstability detecting devices. Each carriage is provided with one bogie unstability detecting device, a bogie unstability output relay and a bogie unstability motion relay; an unstability brake trigger relay and a vehicle-mounted equipment brake instruction relay in a driver cab are controlled to move through a brake control loop penetrating a train; after the bogie unstability detecting device in a certain carriage detects abnormal vibration of the train, the corresponding bogie unstability output relay acts to trigger the corresponding bogie unstability motion relay, the corresponding bogie unstability motion relay is powered on, and a normally-closed contact of the corresponding bogie unstability motion relay in the control loop is disconnected, the corresponding bogie unstability output relay is powered off, the vehicle-mounted equipment brake instruction relay is powered on, and the train conducts braking. By means of the train automatic braking control circuit, the defects that brake control is carried out through a train network system, so that interference and disconnection exist are overcome.

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...
