In the one end of the second trigger far from the second equipment, while the other end for also avoiding third branch is connected to the second equipment and the
In second branch between two branch disconnections.
For the first trigger and the second trigger it should be understood that the first trigger and second in the present embodiment
Trigger can be zero speed relay, wherein the first trigger be the first zero speed relay, the second trigger be the second zero-speed after
Electric appliance.
Specifically, the first zero speed relay may include: the normally-closed contact being set in second branch, and it is set to
The normally opened contact of three roads, wherein normally-closed contact disconnects after the first zero speed relay is activated, to disconnect second branch；
Normally opened contact is closed after the first zero speed relay is activated, to be connected to third branch.
That is, the first zero speed relay by normally-closed contact and normally opened contact controls second branch and the in the present embodiment
The disconnected state of three branches.Specifically, when the first equipment can export the first zero-speed signal by the first branch, the first zero-speed
Relay is activated, and normally-closed contact disconnects, to ensure that the second zero-speed signal of the second equipment output is isolated；Its normally opened contact closes
It closes, to activate the second zero speed relay, wherein target line is connected to after the second zero speed relay is activated, and target device can be with
The first zero-speed signal of the first equipment output is got by target line.
When the first equipment can not export the first zero-speed signal by the first branch, the first zero speed relay is not swashed
It is living.At this point, the normally-closed contact of the first zero speed relay is closed, the second equipment can export the 2nd 0 by the second branch of connection
Fast signal, wherein the second zero-speed signal first activates the second zero speed relay, wherein mesh after the second zero speed relay is activated
The connection of graticule road, target device can get the second zero-speed signal of the second equipment output by target line；First zero-speed
The normally opened contact of relay disconnects, and the second zero-speed signal of the second equipment output can not be transferred to the first zero-speed by third branch
In relay, the case where avoiding circuit disorder generation.
For the first equipment and the second equipment in the present embodiment, it should be understood that preferred high safety of the first equipment etc.
The equipment of grade, that is, the zero-speed signal of high safety grade equipment output is preferentially selected in the present embodiment, in high safety grade
After equipment fault, other zero-speed output equipments are automatically switched to, to select the zero-speed signal of other zero-speed output equipments output,
To guarantee that zero-speed signal can be exported normally, and then rail vehicle is enabled to operate normally.
In a kind of optional example, the equipment that the first equipment uses output signal zero-speed, and the second equipment is using output
The equipment for braking zero-speed, wherein the equipment of output signal zero-speed can be signal system.
In addition, in the present embodiment, which further includes prompting device, wherein reminiscences be used for the first trigger not by
Activation and the second trigger issue the first prompt information in the case where being activated, and are not activated and second in the first trigger
In the case that trigger is not also activated, issue the second prompt information, wherein the first prompt information for prompt the first equipment without
Method exports zero-speed signal, and the second prompt information is for prompting the first equipment and the second equipment that can not export zero-speed signal.
In addition, the device further includes diode in the present embodiment, it is set in second branch as shown in Figure 2.
It should be understood that the first equipment can not export the first zero-speed signal in the case where fail self-test or barrier.
The embodiment of the present application also provides a kind of methods for switching zero speed circuit, it should be noted that the switching zero-speed electricity
This application can be applied to switch the device of zero speed circuit provided by the embodiment of the present application for the method on road.Below to the application reality

Step S302: in the case where the first equipment can export the first zero-speed signal by the first branch, second is disconnected
Road, wherein second branch is used for transmission the second zero-speed signal of the second equipment output, wherein the second zero-speed signal indicates track
The travel speed of vehicle is zero.
Step S303: in the case where the first equipment cannot export the first zero-speed signal by the first branch, connection second
Branch.
Using the technical solution of the present embodiment, by can normally export the first zero-speed by the first branch in the first equipment
Second branch is disconnected when signal, the second zero-speed signal of the second equipment output is isolated；The first branch can be passed through in the first equipment
Second branch is connected when the second zero-speed signal of normal output, the second zero-speed signal exported using the second equipment, to solve to export
When the system jam of zero-speed signal, track train just can not use zero-speed signal control circuit the technical issues of.Reach
After the first equipment fault of output zero-speed signal, the technical effect of the second equipment output zero-speed signal is automatically switched into, simultaneously
Avoiding rail vehicle can not be using generation the case where zero-speed signal control circuit.
For judging whether the first equipment can be in such a way that the first branch normally exports the first zero-speed signal, in this implementation
It can be in example are as follows: the first equipment of control sends the first zero-speed signal to the first trigger by the first branch, is touched with activation first
Send out device；In the case where the first trigger is activated, then it represents that the first equipment can export the first zero-speed signal by the first branch；
In the case where the first trigger is not activated, then it represents that the first equipment cannot export the first zero-speed signal by the first branch.

In the first branch, the other end is connected in the second branch at the disconnection of second branch between the second trigger.
In addition, this method can also include: not to be activated and the second trigger quilt in the first trigger in the present embodiment
In the case where activation, the first prompt information is issued, wherein the first prompt information is for prompting the first equipment that can not export the 1st
Fast signal.Such design makes the first equipment in the case where that can not export the first zero-speed signal, not only from the first equipment output zero
Fast signal automatically switches into second and sets output zero-speed signal, while also the first equipment of automatic prompt staff can not export first
Zero-speed signal grasps the output situation of zero-speed signal convenient for staff in time, so that staff is to the first equipment of failure
On-call maintenance.
And this method can also include: not to be activated and the second trigger in the first trigger in the present embodiment
In the case where not being activated, the second prompt information is issued, wherein the second prompt information is for prompting the first equipment that can not export the
One zero-speed signal, and the second equipment can not also export the second zero-speed signal.Similarly, such design is so that the first equipment and second is set
For when can not export zero-speed signal (the first zero-speed signal and the second zero-speed signal), the first equipment of staff is notified in time
With the second device fails, so that staff is to the first equipment and the second equipment on-call maintenance of failure.
