Description
Technical field
The invention belongs to railcar electrical principle control field, specially a kind of railcar draws/brakes redundancy control
Method processed.
Background technology
Railcar traction/control for brake had two ways in the past, and one kind is based on rigid line control, and another kind is based on net
Network controls.
Earliest traction/control for brake adopt rigid line control, control principle block diagram as shown in Figure 1: driver controller or
The traction of atc output, braking, direction instruction directly pass through hard-wire transfer to traction control unit and brak control unit, draw
Power/demand braking force value is transmitted to traction control unit and brak control unit, traction control after coder transitions are pwm ripple
Unit processed and brak control unit realize train after receiving traction, braking, direction instruction and pull strength/demand braking force value
Traction and braking function.In the deboost phase, there is electric braking and air damping cooperation, in traction control unit and control for brake
Hard signal is set up, such as electric braking force completes value, electric braking status signal, electric braking slide signal, electric braking is light between unit
Go out signal, reference speed signal, load signal, electric braking disable signal.Based on rigid line control, traction/brake control signal passes
Have passed through the conversion links to signal for the encoder, encoder fault will lead to traction/braking function cannot realize, row during defeated
Car can only wait for rescue.
With the development of network technology, traction/control for brake is gradually network controlled replacement, control principle block diagram such as accompanying drawing
Shown in 2: the traction of driver controller or atc output, braking, direction instruction and pull strength/demand braking force value are passed by rigid line
Defeated to mixed-media network modules mixed-media, these signals are transferred to traction control unit and brak control unit by mvb, draw and control for brake
Unit realizes traction and the braking work of train after receiving traction, braking, direction instruction and pull strength/demand braking force value
Energy.In the deboost phase, electric braking force necessary to electricity sky composite braking completes value, electric braking status signal, slides signal, electricity system
The dynamic signal that fades out, reference speed signal, load signal, electric braking disable signal are transmitted again by mvb.Based on mixed-media network modules mixed-media control
System, when train network module breaks down, traction, signal transmission passage necessary to braking are interrupted it is impossible to normally real
Now traction/braking function, even if also can only make train realize restricted traction and braking function, row using urgent traction function
Car can not realize stepless control as normal, and does not enable electricity sky composite braking, can only adopt pure air damping, train work(
Energy is impacted can only the offline Hui Ku of the proteges of the powerful who stay with their benefactions like parasites.
