Embodiment Construction

[0031] Such as figure 1 As shown, in the embodiment of the present invention, the independent brake controller sends a voltage analog signal of 0-10V to the brake control unit BCU through the analog quantity acquisition channel as an input signal for implementing brake pressure. By sending 4 channels of 110V switching signals to the brake control unit BCU as the input signals of different positions of the individual brake controller. The present invention can perform the following three types of fault detection and safety guidance. The separate brake controller of the locomotive brake has four operating positions, namely the operating position, the braking zone, the full braking position and the side pressure relief position. The B01 auxiliary switch of the independent brake controller is at high level in the operating position, braking zone and full braking position. B03 is high level at the operating position of the individual automatic controller, which is used as the inp...

Abstract

The invention discloses a locomotive brake, an independent brake controller guiding control method thereof and a vehicle. If an auxiliary switch contact signal of an independent brake controller is abnormal and an analog quantity signal is normal, a brake instruction of the independent brake controller is controlled by the analog quantity signal, and auxiliary switch fault alarm information is sent out; if the analog quantity control signal of the independent braking controller is abnormal, the auxiliary switch contact signal is normal, and if the independent braking controller recognizes that the auxiliary switch contact is in a braking area, independent full braking is guided, and fault alarm information is sent out; and if the auxiliary switch contact is in a release position, a release signal instruction is sent out. According to the invention, fault judgment and safety guidance are carried out on the independent brake controller by adopting a judgment method of combining auxiliary switch contact signals and analog quantity signals sent by different levels of positions of the independent brake controller so that the reliability and safety of input signals of the brake are improved; and the situation that safe parking cannot be achieved when an independent brake controller breaks down is prevented.

Description

technical field [0001] The invention relates to the technical field of locomotive brake control, in particular to a locomotive brake machine and a guiding control method for a separate brake controller thereof, and a vehicle. Background technique [0002] As a key system for locomotive speed regulation and parking, the locomotive brake is a control system to ensure driving safety, and the individual brake controller is the operating part of the locomotive brake. The control command of the individual brake controller is sent to the brake control unit through the auxiliary switch contactor as a switch signal and an analog signal. After the brake control unit receives the command of the individual brake controller, it Take control. [0003] The independent brake controller is used as the input device of the control signal of the brake machine. The reliability and safety of its signal input play a key role in the control of the brake machine. Ensuring safe parking is a key con...
