FIG. 1 is a schematic diagram of a single slow safety guidance system of an individual brake controller of a locomotive brake in accordance with an embodiment of the present invention;
FIG. 2 is a logic flow diagram of locomotive brake single-slow control according to an embodiment 2 of the present invention.
Detailed Description
As shown in fig. 1, the single-slow safety guidance system of the single brake controller of the locomotive brake in embodiment 1 of the invention comprises the single brake controller, an automatic brake controller, a brake control unit and a brake cabinet.
The individual brake controller is used for a driver operated device which issues individual brake control commands including a single retard bit, a single brake apply release bit and a brake bit.
An automatic brake controller is a driver-operated device for issuing service brake commands and emergency brake commands.
The brake control unit receives a single-buffer relieving command sent by the single brake controller and a brake area command sent by the automatic brake controller, and outputs brake pressure through calculation.
The brake cabinet is used for installing a brake control unit and an electric and gas path interface for braking.
The brake control unit collects corresponding position instruction signals between the single buffer position of the independent brake controller and the common brake instruction or the emergency brake position of the automatic brake controller, judges whether the single buffer position of the independent brake controller exceeds the preset value time or not, and determines the validity of the single buffer position signals.
In the present invention, the position command signals include a service brake command, an emergency brake command of the automatic brake controller and a single slow command of the individual brake controller. The single-slow brake controller is set to be in the single-slow position within the preset value time, the brake control unit considers that the single-slow command signal is effective, and the single-slow signal is output to control the electric and gas circuit of the brake cabinet, so that the safe single-slow function of the common brake and the emergency brake of the locomotive brake is realized; and if the single-slow bit of the single-brake controller exceeds the preset value time, the single-slow instruction signal is invalid. When the single buffer is reset again, the single buffer instruction signal is timed again, and the brake control unit judges the validity of the single buffer instruction signal again.
The service braking instruction and the emergency braking instruction of the automatic braking controller are prior to the single slow instruction of the single braking controller, namely when the single slow instruction is continuously output by the single braking controller, if the service braking or the emergency braking instruction is output by the automatic controller, the service braking or the emergency braking instruction is identified by the braking control unit.

Step 2: if a rising edge signal of a service brake instruction of the automatic brake controller is received firstly, and then a single slow instruction signal of the single brake controller is received, the single slow instruction signal exceeds the preset value time K, and the service brake is considered to be unavailable. The preset value time K can be set when the single buffer is blocked or the collection of the brake control unit is invalid, so that the brake cylinder of the brake is prevented from being relieved to influence the application safety of the locomotive due to the single buffer action of the service brake or the emergency brake.
And step 3: if the signal of the common brake command rising edge of the automatic brake controller is received, the single slow command signal of the independent brake controller cannot be received, and the common brake is considered to be unavailable.
And 4, step 4: and if the rising edge signal of the service braking instruction of the automatic braking controller is not received, the service braking is considered to be unavailable slowly.
And 5: when the service brake is available, the service brake single-slow signal is output to control the brake cabinet to execute the service brake single-slow function.
Step 6: when the service brake single buffer is unavailable, if the single buffer command signal is reset, the judgment of the single buffer control logic is carried out again; if the single slow command signal is not reset, the brake cylinder pressure is kept in the last single slow state, and when automatic braking is added or applied again, the single slow brake cannot be controlled to relieve the pressure of the brake cylinder of the service brake, and the brake cylinder pressure is kept at the pressure during automatic braking control.
And 7: if an emergency braking instruction rising edge signal of the automatic braking controller is received firstly, and then a single-buffer instruction signal of the independent braking controller is received, the single-buffer signal is within a preset value time K, and the emergency braking instruction signal is effective, and the single-buffer emergency braking is considered to be available.
And 8: if an emergency braking instruction rising edge signal of the automatic braking controller is received firstly, and then a single slow instruction signal of the single braking controller is received, the single slow instruction signal exceeds the preset value time K, and the single slow of the emergency braking is considered to be unavailable.
And step 9: if the rising edge signal of the emergency braking instruction of the automatic braking controller is received firstly, and then the single slow instruction signal of the single braking controller is received, the single slow instruction signal is within the preset value time K, but the emergency braking instruction signal is not kept, and the single slow of the emergency braking is considered to be unavailable.
Step 10: if the rising edge signal of the emergency braking instruction of the automatic braking controller is received, but the single slow instruction signal of the single braking controller is not received, the single slow of the emergency braking is considered to be unavailable.
Step 11: and if the rising edge signal of the emergency braking instruction of the automatic braking controller is not received, the emergency braking is considered to be unavailable slowly.
Step 12: when the emergency brake is available, the emergency brake signal is output to control the brake cabinet to perform the emergency brake function.
Step 13: when the emergency braking single buffer is unavailable, if the single buffer command signal is reset, the judgment of the single buffer control logic is carried out again; if the single slow command signal is not reset, the pressure of the brake cylinder is recovered, and the single slow brake can not be controlled to relieve the pressure of the emergency brake cylinder.
