A Communication-Based Train Control System (CBTC) is a System that performs real-time bidirectional wireless Communication with ground equipment through a Train to realize safe operation of the Train, and the Train Control level is generally divided into a CBTC Control Mode and a backup Control Mode (Block Mode, BM). The CBTC is a normal control mode, when the CBTC is unavailable due to the failure of some equipment, the backup control mode can increase the availability of the system, and the line can continue to operate. In a backup control mode, a train realizes automatic protection control of the train through a signal machine safety interval, an interlocking machine sends calculated status information of trackside equipment to an active beacon through a beacon encoder through an interface circuit and finally transmits the status information to train-mounted equipment, and the interface circuit between the beacon encoder and the interlocking machine is an important ring in the transmission process and is an important guarantee for safe operation of the train. In the existing interface circuit, only a train signal relay, a turnout positioning indication relay and a turnout reversal indication relay which indicate the open or close state of a signal machine are deployed, so that the deployment problem is that the circuit does not identify a coming train mode and is always conducted, and the following problem can be caused. To this end, the present application provides an interface circuit for use between a beacon encoder and an interlock machine. Let interface circuit can discern the mode of coming the train to the security when promoting the train operation.
For example, referring to fig. 1 and fig. 9, fig. 1 is a schematic diagram of an overall structure of an interface circuit used between a beacon encoder and an interlocking machine provided in the present application; fig. 9 is a schematic diagram of an overall structure of an interface circuit between a beacon encoder and an interlocking machine provided in the present application when the interface circuit is packaged; as shown in fig. 1, the present application provides an interface circuit 10 for use between a beacon encoder and an interlock machine, comprising: lighting relays 141 and 142, wherein the first and second lighting relays 141 and 142; train signal relays 131 and 132, wherein the first train signal relay 131 and the second train signal relay 132; switch positioning indication relays 151 and 152, wherein a first switch positioning indication relay 151 and a second switch positioning indication relay 152 are arranged; the switch reverse indicates the relays 161 and 162, wherein the first switch reverse indicates the relay 161 and the second switch reverse indicates the relay 162. As shown in fig. 9, the interface circuit 10 is packaged in the combination cabinet 17, and the connection lines of the interface circuit 10 connected to the first interface cabinet 122 and the second interface cabinet 121 extend out of the combination cabinet 17 so as to be connected to the first interface cabinet 122 and the second interface cabinet 121.
The relays are connected to the contacts of the positive and negative parts of the interface circuit 10, respectively, and the following description is given:
the first ends of the first lighting relay 141 and the second lighting relay 142 are connected to the second end of the first interface cabinet 122 through a connection line and a connection terminal, and then the first end of the first interface cabinet 122 is connected to the interlocking machine 13, so that the first lighting relay 141 and the second lighting relay 142 are connected to the interlocking machine 13.
Then the second end of the first ignition relay 141 is electrically connected to the first end of the first train signal relay 131, the first end of the first turnout positioning indicating relay 151 and the first end of the first turnout reverse indicating relay 161 respectively; a second end of the second lighting relay 142 is electrically connected to a first end of the second train signal relay 132, a first end of the second switch position indication relay 152, and a first end of the second switch reverse indication relay 162, respectively.
Further, the second end of the first train signal relay 131, the second end of the second train signal relay 132, the second end of the first switch position indication relay 151, the second end of the second switch position indication relay 152, the second end of the first switch inversion indication relay 161, and the second end of the second switch inversion indication relay 162 are connected to the first end of the second interface cabinet 121 through connecting wires and connecting terminals, respectively, and the second end of the second interface cabinet 121 is connected to the beacon encoder 11, so as to achieve the connection between the second end of the first train signal relay 131, the second end of the second train signal relay 132, the second end of the first switch position indication relay 151, the second end of the second switch position indication relay 152, the second end of the first switch inversion indication relay 161, and the second end of the second switch inversion indication relay 162 and the beacon encoder 11.
The first lighting relay 141, the first train signal relay 131, the first turnout positioning indication relay 151 and the first turnout reversal indication relay 161 are connected to a positive part in the interface circuit 10; the second lighting relay 142, the second train signal relay 132, the second switch positioning indication relay 152 and the second switch reverse position indication relay 162 are respectively connected to the negative electricity part in the interface circuit 10.
It should be further noted that the first train signal relay 131, the first switch location indication relay 151, and the first switch reverse indication relay 161 are connected in parallel, that is, all the three are connected to the first lighting relay 141, but the three are not interfered with each other, the second train signal relay 132, the second switch location indication relay 152, and the second switch reverse indication relay 162 are the same as the first train signal relay 131, the first switch location indication relay 151, and the first switch reverse indication relay 161, and no repeated description is given.
Whether the first lighting relay 141 and the second lighting relay 142 are closed depends on the driving of the interlocking machine 13, and if the interlocking machine 13 recognizes that the coming train mode is a non-CBTC train mode, the first lighting relay 141 and the second lighting relay 142 are driven to be closed; when the interlock device 13 recognizes that the outdoor traffic signal is open, the first train signal relay 131 and the second train signal relay 132 are driven to close.
The switch indication relays 151, 152, 161, and 162 are driven by a switch indication circuit (not shown) to reflect the actual situation of the outdoor switch, and if the switch is positioned, the first switch positioning indication relay 151 and the second switch positioning indication relay 152 are closed; if the turnout is in reverse, the reverse of the first turnout indicates that the relay 161 is closed, and the reverse of the second turnout indicates that the relay 162 is closed.
The non-labeled parts in all figures of the application are connecting lines and connecting terminals.
In actual work, reference may be made to fig. 2, where fig. 2 is a schematic diagram of a closed condition of an interface circuit when a lighting relay is closed in the interface circuit between a beacon encoder and an interlock machine, a semaphore is open, and a switch is positioned, where a specific work flow is as follows:
before the description, it should be noted that the states of the first lighting relay 141 and the second lighting relay 142 should be kept consistent, that is, both should be closed if they are closed, and if they are not consistent, the circuit cannot be conducted; the states of the first train signal relay 131 and the second train signal relay 132 should be kept consistent, the states of the first turnout location indication relay 151 and the second turnout location indication relay 152 should be kept consistent, the states of the first turnout reversal indication relay 161 and the second turnout reversal indication relay 162 should also be kept consistent, if the states are not consistent, the interface circuit 10 cannot be conducted, and therefore through double-circuit control, the fault probability of circuit conduction caused by mixed power is effectively reduced, and the safety of the circuit is greatly improved.
The following is a specific process: when the interlocking machine 13 recognizes that the coming train mode is a train with a non-CBTC mode, the first lighting relay 141 and the second lighting relay 142 are driven to be closed, the circuit has a conduction condition, and further, if the signaler satisfies an opening condition, the interlocking machine 13 drives the first train signal relay 131 and the second train signal relay 132 to be closed, meanwhile, if the turnout is positioned, the turnout indication circuit (not shown) drives the first turnout location indication relay 151 and the second turnout location indication relay 152 to be closed, the closed state of the relays can be output to the beacon encoder 11 through the second interface cabinet 121, and after the beacon encoder 11 obtains a signal, the output code bits are the signaler opening condition: 1; and (3) positioning conditions of turnouts: 1; the switch reverse situation: 0.
further, please refer to fig. 3, fig. 3 is a schematic diagram of a closed condition of an interface circuit when a lighting relay is closed, a semaphore is open, and a switch is in a reverse position in the interface circuit between a beacon encoder and an interlock machine, according to fig. 3, the work flow is as follows:
when the interlocking machine 13 recognizes that the coming train mode is a train with a non-CBTC mode, the first lighting relay 141 and the second lighting relay 142 are driven to be closed, the circuit has a conduction condition, and further, if the signaler satisfies an opening condition, the interlocking machine 13 drives the first train signal relay 131 and the second train signal relay 132 to be closed, meanwhile, if the turnout is in a reverse position, the turnout indication circuit (not shown) drives the first turnout reverse position indication relay 161 and the second turnout reverse position indication relay 162 to be closed, the closed state of the relays can be output to the beacon encoder 11 through the second interface cabinet 121, and after the beacon encoder 11 obtains a signal at the moment, the output code bit is the signaler opening condition: 1; and (3) positioning conditions of turnouts: 0; the switch reverse situation: 1.
further, please refer to fig. 4, fig. 4 is a schematic diagram of the closing condition of the interface circuit when the lighting relay is closed, the annunciator is closed, and the switch is positioned in the interface circuit between the beacon encoder and the interlock machine, which is provided by the present application, as shown in fig. 4, the work flow is as follows:
when the interlock device 13 recognizes that the coming train mode is a non-CBTC mode train, the first lighting relay 141 and the second lighting relay 142 are driven to be closed, the circuit has an on condition, and if the traffic signal does not satisfy the open condition, the first train signal relay 131 and the second train signal relay 132 are kept in an off state. If the switch is located, the switch indicating circuit (not shown) drives the first switch location indicating relay 151 and the second switch location indicating relay 152 to be closed, the closed state of the relays can be output to the beacon encoder 11 through the second interface cabinet 121, and after the beacon encoder 11 obtains a signal at this time, the output code bit is the open condition of the signaler: 0; and (3) positioning conditions of turnouts: 1; turnout inversion condition: 0.
further, please refer to fig. 5, fig. 5 is a schematic diagram of the closing condition of the interface circuit when the lighting relay is closed, the annunciator is closed, and the switch is in the reverse position in the interface circuit between the beacon encoder and the interlock machine, as shown in fig. 5, the specific work flow is as follows:
when the interlock device 13 recognizes that the coming train mode is a non-CBTC mode train, the first lighting relay 141 and the second lighting relay 142 are driven to be closed, the circuit has an on condition, and the first train signal relay 131 and the second train signal relay 132 are kept in an off state if the traffic signal does not satisfy the open condition. If the turnout is in the inverted position, the turnout indication circuit (not shown) drives the first turnout inverted position indication relay 161 and the second turnout inverted position indication relay 162 to be closed, the closed state of the relays can be output to the beacon encoder 11 through the second interface cabinet 121, and after the beacon encoder 11 obtains a signal at the moment, the output code bit is the open condition of the annunciator: 0; and (3) positioning conditions of turnouts: 0; the switch reverse situation: 1.
in addition to the above embodiments, in some particular embodiments, the interface circuit 10 does not include the first train signal relay 131 and the second train signal relay 132. Specifically, referring to fig. 6, fig. 6 is a schematic diagram of an overall structure of an interface circuit used between a beacon encoder and an interlocking machine when a train is located upstream of a platform and is in a station type with an interlocking boundary and an outbound direction close to a switch fork according to the present application.
In addition, even if the train is in an upstream interval, the state of the outbound signal machine is predicted, and the train may be invalid at the departure time, so that the state of the outbound signal machine does not need to be predicted in advance at the upstream of the platform. Correspondingly, in the corresponding interface circuit, a train signal relay of the outbound signal machine does not need to be deployed.
Each route starting-end signal machine can be deployed with a re-opening beacon for providing the state of the signal machine for the train and forecasting the state information of the signal machines and the turnouts in the downstream section, and in addition, a plurality of forecasting beacons are additionally arranged at necessary positions in the section and used for forecasting the state information of the signal machines and the turnouts in the downstream section so as to improve the running efficiency of the train and ensure the stop in place. However, since the beacon encoder can only be connected to one interlocking machine, the active beacon connected to it can only contain the variables of a single interlocking area. In a station type in which the upstream of the platform is an interlocking boundary and the departure direction is close to the switch fork, the state of the switch of the next interlocking area needs to be known in advance when the train stops at the platform, and therefore, IB1 (announcement beacon) belonging to the interlocking area needs to be arranged to announce the state of the switch of the next interlocking area.
Therefore, in the station type in which the upstream of the platform is the interlocking boundary and the outbound direction is close to the switch bifurcation, the interface circuit 10 only needs to dispose the lighting relays 141 and 142, the switch positioning indicating relays 151 and 152, and the switch inversion indicating relays 161 and 162.
Whether the station is an interlocking boundary upstream of the station, the station type with the outbound direction immediately adjacent to the switch fork, or other station types, the interface circuit 10 is enclosed in a combination cabinet 17, as shown in fig. 10.
Further, as shown in fig. 7, fig. 7 is a schematic diagram of an interface circuit used between a beacon encoder and an interlocking machine, when a train is located upstream of a platform and is an interlocking boundary, and an outbound direction is in a station type of a switch fork, a lighting relay is closed, and the interface circuit is closed when the switch is positioned, as shown in fig. 7, a work flow is as follows:
