[0032] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0033] MCR: Main Controller
[0034] ATP: Automatic Train Protection
[0035] TCMS: Train Network Control and Management System
[0036] Example 1
[0037] This embodiment discloses a forward operation control system for an automatic turnaround process, such as... Figure 1It includes: a start branch, an MCR branch, a command interlock branch, and a monitoring branch. The start branch is used to receive the automatic turnaround command of the train and send a turnaround signal according to the automatic turnaround command. The MCR branch is connected to the start branch and is used to keep the MCR in the driver's cab energized according to the turnaround signal. The command interlock branch is connected to the start branch and is used to keep the train in a forward running state according to the turnaround signal.
[0038] Specifically, such as Figure 2 The starting branch includes an automatic turnaround button (ATO) installed in the driver's cab, an ATP module, and an automatic turnaround relay (ZFJHR). The automatic turnaround button (ATO) is connected to the coil of the automatic turnaround relay (ZFJHR) through the ATP module.
[0039] Specifically, such as Figure 3 The MCR branch includes a key command interface BOR located in the driver's cab, an MCR located in the driver's cab, and the first normally open contact of the automatic return relay ZFJHR. The key command interface BOR is connected to the MCR, and the first normally open contact of the automatic return relay ZFJHR is connected in parallel across the key command interface BOR.
[0040] Specifically, such as Figure 4 The command interlock branch includes a train direction handle DS, a forward control relay DSDFR, a backward control relay DSDRR, a forward relay DFR, and a backward relay DRR, all located in the driver's cab. The train direction handle is connected to the coils of the forward control relay DSDFR and the backward control relay DSDRR, respectively. One end of the normally closed contact of the forward relay DFR is connected to the train direction handle, and the other end is connected in series with the normally open contact of the backward control relay DSDRR and the coil of the backward relay DRR. One end of the normally closed contact of the backward relay DRR is connected to the train direction handle, and the other end is connected in series with the second normally open contact of the automatic reversing relay ZFJHR and the coil of the forward relay DFR. The normally open contact of the forward control relay DSDFR is connected in parallel across the two ends of the second normally open contact of the automatic reversing relay ZFJHR.
[0041] Specifically, such as Figure 5 The monitoring branch includes the third normally open contact of the automatic reversing relay ZFJHR, the normally open contact of the MCR, the normally open contact of the forward relay DFR, and the reversing activation feedback relay ZFJHRR. One end of the third normally open contact of the automatic reversing relay ZFJHR is connected in series with the coil of the normally open contact of the MCR, the normally open contact of the forward relay DFR, and the reversing activation feedback relay ZFJHRR and grounded. The other end of the third normally open contact of the automatic reversing relay ZFJHR is connected to the normally open contact of the reversing activation feedback relay ZFJHRR. The other end of the normally open contact of the reversing activation feedback relay ZFJHRR is connected to the TCMS through the ATP module.
[0042] The following explanation is based on the specific implementation process:
[0043] When automatic reversal is required, the train direction handle DS is in the closed position. The driver first removes the key inserted in the driver's cab key command interface BOR, at which point the MCR is de-energized. Then, the driver presses the automatic reversal button ATO in the driver's cab, the ATP module activates the automatic reversal relay ZFJHR, the automatic reversal relay ZFJHR is energized, and the first, second, and third normally open contacts of the automatic reversal relay ZFJHR are all closed. At this time, the MCR remains energized.
[0044] When the coil of the forward relay DFR is energized, its normally open contact closes and its normally closed contact opens, ensuring that the coil of the backward relay DRR is not energized, thus achieving directional command interlocking. At this time, the coil of the turnaround activation feedback relay ZFJHRR is energized, and its normally open contact closes. The ATP module detects the closure of the normally open contact of the turnaround activation feedback relay ZFJHRR and considers that the train has achieved a lock-in forward running state, i.e., the automatic turnaround preparation is complete, and feedback is sent to the TCMS.
[0045] If the normally open contact of the turnaround activation feedback relay ZFJHRR is not detected to be closed after the ATP module activates the automatic turnaround relay ZFJHRR, it is considered that the vehicle has not completed the forward running lock, that is, the automatic turnaround preparation has not been completed, and feedback is given to TCMS. TCMS then sends a warning message to the driver.
[0046] When the train is running normally and the train direction handle DS is in the "forward" position, the coil of the forward control relay DSDFR is energized, the normally open contact of the forward control relay DSDFR closes, the coil of the forward relay DFR is energized, and the train moves forward; at the same time, the normally closed contact of the forward relay DFR opens to ensure that the coil of the backward relay DRR is not energized.
[0047] When the train is running normally and the train direction handle DS is in the "reverse" position, the coil of the reverse control relay DSDRR is energized, the normally open contact of the reverse control relay DSDRR closes, the coil of the reverse relay DRR is energized, and the train moves in the reverse direction; at the same time, the normally closed contact of the reverse relay DRR opens, ensuring that the coil of the forward relay DFR is not energized.
[0048] In the automatic turnaround activation mode, the vehicle issuing a forward command is a necessary condition for the on-board signaling system to realize the automatic turnaround of the vehicle. The present invention can lock the train in the forward running state through the command interlock unit, meet the operating conditions of automatic turnaround, and ensure the normal operation of the vehicle through the direction command interlock, thereby improving driving safety.
[0049] Example 2
[0050] This embodiment discloses a forward operation control method for an automatic turnaround process, used to implement the control system described in Embodiment 1. The control method includes the following steps:
[0051] S1. Initiate branch circuit detection and receive automatic train turnaround command, and send automatic train turnaround signal according to the automatic turnaround command. Specifically, the branch circuit includes an automatic turnaround button, an ATP module, and an automatic turnaround relay located in the driver's cab. The automatic turnaround button is connected to the coil of the automatic turnaround relay through the ATP module.
[0052] S2, the MCR branch keeps the driver's cab MCR energized according to the train's automatic turnaround signal. Specifically, the MCR branch includes a key command interface located in the driver's cab, an MCR located in the driver's cab, and the first normally open contact of the automatic turnaround relay. The key command interface is connected to the MCR, and the first normally open contact of the automatic turnaround relay is connected in parallel across the key command interface.
[0053] S3. The command interlock branch interlocks the direction commands based on the automatic turnaround signal to keep the train in a forward running state. Specifically, the command interlock branch includes a train direction handle, a forward control relay, a backward control relay, a forward relay, and a backward relay installed in the driver's cab. The train direction handle is connected to the coils of the forward control relay and the backward control relay, respectively. One end of the normally closed contact of the forward relay is connected to the train direction handle, and the other end is connected in series with the normally open contact of the backward control relay and the coil of the backward relay. One end of the normally closed contact of the backward relay is connected to the train direction handle, and the other end is connected in series with the second normally open contact of the automatic turnaround relay and the coil of the forward relay. The normally open contact of the forward control relay is connected in parallel across the two ends of the second normally open contact of the automatic turnaround relay.
[0054] In one embodiment, a monitoring branch is also included, which includes a third normally open contact of an automatic reversing relay, a normally open contact of an MCR, a normally open contact of a forward relay, and a reversing activation feedback relay. One end of the third normally open contact of the automatic reversing relay is connected in series with the coils of the normally open contacts of the MCR, the forward relay, and the reversing activation feedback relay and grounded. The other end of the third normally open contact of the automatic reversing relay is connected to the normally open contact of the reversing activation feedback relay. The other end of the normally open contact of the reversing activation feedback relay is connected to the TCMS through an ATP module.
[0055] When automatic reversal is required, the train direction handle DS is in the off position. The driver first removes the key inserted in the key command interface in the driver's cab, at which point the MCR is de-energized. Then, the driver presses the automatic reversal button in the driver's cab, the ATP module activates the automatic reversal relay, the automatic reversal relay is energized, and the first, second, and third normally open contacts of the automatic reversal relay are all closed. At this time, the MCR remains energized.
[0056] When the coil of the forward relay is energized, its normally open contact closes and its normally closed contact opens, ensuring that the coil of the backward relay is not energized, thus achieving directional command interlocking. At this time, the coil of the reversal activation feedback relay is energized, and its normally open contact closes. The ATP module detects the closure of the normally open contact of the reversal activation feedback relay and considers that the vehicle has achieved the train-locked forward running state, maintaining forward running, thus completing the automatic reversal preparation, and feeding back to the TCMS.
[0057] If the ATP module activates the automatic turnaround relay but does not detect the normally open contact of the turnaround activation feedback relay closing and / or detects that the driver's cab MCR is not energized, it is considered that the vehicle has not completed the train forward running lock, that is, it has not completed the automatic turnaround preparation. The ATP module issues an alarm and feeds back to the TCMS, and the TCMS sends a warning message to the driver.
[0058] When the train is running normally and the train direction handle is in the "forward" position, the coil of the forward control relay is energized, the normally open contact of the forward control relay closes, the coil of the forward relay is energized, and the train moves forward; at the same time, the normally closed contact of the forward relay opens to ensure that the coil of the backward relay is not energized.
[0059] When the train is running normally and the train direction handle is in the "reverse" position, the coil of the reverse control relay is energized, the normally open contact of the reverse control relay closes, the coil of the reverse relay is energized, and the train moves in reverse; at the same time, the normally closed contact of the reverse relay opens to ensure that the coil of the forward relay is not energized.
[0060] This invention enables trains to maintain forward movement, meeting the conditions for automatic turnaround, and ensures normal vehicle operation through directional command interlocking, thereby improving driving safety.
[0061] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
