It should be noted that a kind of preferred embodiment as the present embodiment, to a kind of train emergency braking loop control
Scheme processed illustrates：
A kind of novel emergency braking loop control program, is related to train brake control field, braking control system belongs to row
The highly safe system of vehicle, therefore the reliability of control for brake and safety are particularly important in control circuit design；This programme
On the basis of traditional single emergency braking loop, it is proposed that a kind of redundant emergency brake loop control program, this scheme are additional
Configuration one brakes the identical Article 2 emergency braking loop of loop with normal emergency, appoints in first emergency braking loop
When what position is broken down, directly Article 2 can be selected urgent by operating emergency braking loop selecting switch (BLSS)
The control that loop participates in train is braked, rather than directly cuts off emergency braking loop, to improve the reliability of train operation.
The present invention can avoid arranging caused by emergency braking loop fault in the case where not cutting off emergency braking loop
Vehicle erroneous trigger emergency braking, causes Train delay, and extraneoas loss is brought to passenger, to improve entire rail traffic operation system
The reliability of system.The invention belongs to the product independent research technologies that is put on sale.
For the problems of the prior art, the Novel electric that can improve emergency braking control circuit reliability has been invented herein
Road scheme.Propose a kind of redundant emergency brake loop control circuit, this programme by way of redundancy additional configuration one with
Normal emergency brakes the identical emergency braking loop of loop, in first urgent system by way of intermediate relay conversion
It, can be directly by operating emergency braking loop when dynamic loop breakdown causes the emergency braking of train erroneous trigger that can not alleviate
Selecting switch (BLSS) selects Article 2 emergency braking loop to participate in the control of train, rather than directly cuts off emergency braking ring
Road can continue all trigger condition normal operations for ensureing emergency braking, improve the reliability of Train Control in this way；And electricity
Road is directly automatically switched by rigid line, rapid reaction, the problem of there's almost no delay.
