Drawings
FIG. 1 is a schematic diagram of a reliable output brake release application state circuit for a rail transit vehicle of the present invention.
Detailed Description
The embodiments of the present invention are explained below.
As shown in fig. 1, the circuit for a rail transit vehicle of the present embodiment reliably outputs a brake release application state, including a brake release train line L1 and a brake application train line L2 that extend through the whole vehicle;
each vehicle is provided with: a remote input/output module RIOM; the first brake release relay BRR1 and the second brake release relay BRR2 are respectively in one-to-one correspondence with the bogie; and a first bogie isolation valve BBIV1 and a second bogie isolation valve BBIV2 which are respectively in one-to-one correspondence with the bogies.
The first normally open contact BRR1-1 of the first brake release relay BRR1 and the first normally open contact BRR2-1 of the second brake release relay BRR2 are connected in series to the brake release train line L1.
The first output port RIOM-1 of the remote input/output module RIOM is connected in series with the second normally open contact BRR2-2 of the second brake release relay BRR2 and then connected in parallel with the first normally open contact BRR1-1 of the first brake release relay BRR 1. The second output port RIOM-2 of the remote input/output module RIOM is connected in series with the second normally open contact BRR1-2 of the first brake release relay BRR1 and then connected in parallel with the first normally open contact BRR2-1 of the second brake release relay BRR 1.
The first normally-closed contact BRR1-3 of the first brake release relay BRR1 and the first normally-closed contact BRR2-3 of the second brake release relay BRR2 are connected in series to a brake application train line L2, the normally-open contact BBIV1-1 of the first bogie isolation valve BBIV1 is connected in parallel with the first normally-closed contact BRR1-3 of the first brake release relay BRR1, and the normally-open contact BBIV2-1 of the second bogie isolation valve BBIV2 is connected in parallel with the first normally-closed contact BRR2-3 of the second brake release relay BRR 2.
The head car is provided with a brake release power supply circuit for connecting a train power supply and a brake release monitoring port TCMS-1 and a brake application power supply circuit for connecting the train power supply and a brake application monitoring port TCMS-2, wherein the brake release power supply circuit is connected with a first normally closed contact COR1 of a cab activation relay and a first normally open contact COR3 of the cab activation relay in series, and the brake application power supply circuit is connected with a second normally closed contact COR2 of the cab activation relay and a second normally open contact COR4 of the cab activation relay in series. The end part of the brake release train line L1 is connected between a first normally closed contact COR1 of the cab activation relay and a first normally open contact COR3 of the cab activation relay. The end of the brake application train line L2 is connected between the cab activation relay second normally closed contact COR2 and the cab activation relay second normally open contact COR4. The train power supply of the head car is respectively connected with a first normally closed contact COR1 of the cab activation relay and a second normally closed contact COR2 of the cab activation relay after passing through a brake state breaker BSCB. The braking state breaker BSCB is connected in series with an anti-reverse flow diode D1.
When the driver cab of the side is activated, a driver cab activation relay of the driver cab of the side is electrified, a first normally closed contact COR1 and a second normally closed contact COR2 of the driver cab activation relay of the side are disconnected, a first normally open contact COR3 and a second normally open contact COR4 of the driver cab of the side are closed, the opposite side driver cab is in an unactivated state, the activation relay of the driver cab is not electrified, a brake release train line L1 and a brake application train line L2 penetrating through the whole vehicle are powered by a train power supply of the opposite side driver cab, and detection of a brake release signal and a brake application signal are respectively carried out through a brake release monitoring port TCMS-1 and a brake application monitoring port TCMS-2 of the local driver cab.
The remote input/output module RIOM acquires the state of the brake release relay of each bogie in real time, when the first brake release relay BRR1 is monitored to be faulty, the first output port RIOM-1 of the remote input/output module RIOM is closed, the first normally open contact BRR1-1 of the first brake release relay BRR1 is shielded, and a brake release signal is output outwards by the second brake release relay BRR2 corresponding to the adjacent bogie. When the second brake release relay BRR2 is monitored to be faulty, a second output port RIOM-2 of the remote input/output module RIOM is closed, a first normally open contact BRR2-1 of the second brake release relay BRR2 is shielded, and a brake release signal is output outwards by the first brake release relay BRR1 corresponding to the adjacent bogie.
Therefore, when a certain bogie brake release relay fails, the output port of the remote input/output module of the failed bogie and the contact point of the adjacent bogie brake release relay are connected in parallel, so that the train line L1 can output a whole-vehicle brake release signal.
When the first brake release relay BRR1 is monitored to be faulty, the normally open contact BBIV1-1 of the first bogie isolation valve BBIV1 is closed to shield the first normally closed contact BRR1-3 of the first brake release relay BRR1, and a brake application signal is output through the normally closed contact BBR2-3 of the second brake release relay BRR2 and the normally open contact BBIV1-1 of the first bogie isolation valve BBIV1 which are connected in series. When the second brake release relay BRR2 is detected to be faulty, the normally-open contact BBIV2-1 of the second bogie isolation valve BBIV2 is closed to shield the first normally-closed contact BRR2-3 of the second brake release relay BRR2, and a brake application signal is output through the normally-closed contact BBR1-3 of the first brake release relay BRR1 and the normally-open contact BBIV2-1 of the second bogie isolation valve BBIV2 which are connected in series.
It can be seen that when a certain truck brake release relay fails, the failed brake release relay contacts can be bypassed by the parallel truck isolation valves, so that the trainline L2 can output the entire vehicle brake application signal.
As shown in fig. 1, each vehicle is further provided with a vehicle isolation valve CBIV, and a normally open contact CBIV-1 of the vehicle isolation valve CBIV is connected in parallel to the outer ends of a first normally closed contact BRR1-3 of the first brake release relay BRR1 and a first normally closed contact BRR2-3 of the second brake release relay BRR 2.
When the first bogie isolating valve BBIV1 or the second bogie isolating valve BBIV2 fails, the normally open contact CBIV-1 of the bogie isolating valve CBIV is closed, and the failed bogie isolating valve contact is bypassed, so that the brake application train line L2 outputs a complete vehicle brake application signal.
In addition to the embodiments described above, other embodiments of the invention are possible. All technical schemes formed by equivalent substitution or equivalent transformation fall within the protection scope of the invention.
