[0002] The phase separation area is an electric-free section of the electrified railway. Different phases of electricity supplied by different substations are isolated by two phase separation switches to prevent short circuit of different phases from causing tripping of substations, fusing of catenary and other accidents.

[0003] Currently, for a heavy-haul marshalling train, the automatic phase separation device of the lead car is mainly used to detect the phase signal from the ground magnetic induction coil, and the heavy-haul marshalling train uses the phase signal received by the lead car to realize automatic phase separation control. When the heavy-haul marshalling train receives the phase signal, the main circuit breaker will be opened, and the train will run through the phase separation area by inertia.

[0045] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application is further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0046] The train through phase redundancy control method provided by the embodiment of the present application can be applied to an application environment as shown in Figure 1 . The terminal 102 interacts with the server 104 through a wired channel / wireless channel. The data storage system can store data required to be processed by the server 104. The re-connection marshalling train includes a master control car and at least one slave control car, and the master control car and the slave control car are both loaded with automatic through phase devices for collecting phase difference signals. Specifically, S1, determining whether each automatic through phase device has a fault, and sending the phase difference signals collected by each automatic through phase device to the master control car and the slave control car; S2, when the automatic through phase detection device of the master control car has a fault, determining a slave control car corresponding to a first automatic through phase device without a fault as a target slave control car along the running direction of the re-connection marshalling train; S3, determining a first distance between the master control car and a phase pre-warning point when the master control car receives a target phase difference signal corresponding to the target slave control car based on the position serial number of the target slave control car and the result of multiplying a preset car length; S4, determining a second distance between the master control car and a phase strong break point when the master control car receives the target phase difference signal based on the difference between a preset phase distance and the first distance, and cutting off the automatic through phase function of the re-connection marshalling train when the second distance is less than a preset safety distance. The terminal 102 can be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, Internet of Things devices, etc. The server 104 can be a server, a server cluster composed of multiple servers, or a cloud computing center composed of multiple servers.

[0047] In an embodiment, as shown in Figure 2 , a train through phase redundancy control method is provided. Taking the server 104 in Figure 1 as an example for illustration, the re-connection marshalling train includes a master control car and at least one slave control car, and the master control car and the slave control car are both loaded with automatic through phase devices for collecting phase difference signals. The train through phase redundancy control method includes the following steps:

[0048] S1, determining whether each automatic neutral section passing device has a fault, and sending the phase-fault signal collected by each automatic neutral section passing device to the lead vehicle and the follower vehicle.

[0049] The lead vehicle is located at the head of the double-heading marshalling train. The automatic neutral section passing device collects the phase-fault signal by detecting the ground magnetic induction coil. The phase-fault signal is used to indicate that the double-heading marshalling train is about to enter the transition area between different power supply partitions, i.e., the neutral section or the no-power area. The phase-fault signal helps the control system on the double-heading marshalling train and the driver to prepare and perform the neutral section passing operation, ensuring that the double-heading marshalling train can safely and smoothly pass through the transition area.

[0050] In some embodiments, whether each automatic neutral section passing device has a fault can be determined by the state information of the automatic neutral section passing device sent to the train gateway. Whether the automatic neutral section passing device of the follower vehicle has a fault can also be determined according to whether the phase-fault signal is sent to the lead vehicle. For example, if the automatic neutral section passing device configured in the follower vehicle A does not send the phase-fault signal to the lead vehicle, it can be determined that the automatic neutral section passing device configured in the follower vehicle A has a fault.

[0051] Sending the phase-fault signal collected by each automatic neutral section passing device to the lead vehicle and the follower vehicle can ensure that the lead vehicle and the follower vehicle can synchronously receive the same phase-fault signal and make consistent operational responses according to the phase-fault signal, so that the lead vehicle and the follower vehicle work cooperatively and smoothly pass through the neutral section.

[0052] S2, when the automatic neutral section passing detection device of the lead vehicle has a fault, determining the follower vehicle to which the first automatic neutral section passing device without a fault belongs as the target follower vehicle along the running direction of the double-heading marshalling train.

[0053] The determination of the follower vehicle to which the first automatic neutral section passing device without a fault belongs as the target follower vehicle along the running direction of the double-heading marshalling train can also be understood as judging whether the automatic neutral section passing device of each follower vehicle has a fault in sequence according to the running order of the double-heading marshalling train from the lead vehicle until the first automatic neutral section passing device without a fault is found. For example, when the automatic neutral section passing device of the lead vehicle has a fault and the automatic neutral section passing device of the follower 1 vehicle has no fault, the follower 1 vehicle is the target follower vehicle; when the automatic neutral section passing devices of the lead vehicle and the follower 1 vehicle have faults and the automatic neutral section passing device of the follower 2 vehicle has no fault, the follower 2 vehicle is the target follower vehicle.

[0054] In some embodiments, the lead vehicle can receive multiple phase-fault signals. When the lead vehicle receives multiple phase-fault signals and the automatic neutral section passing detection device of the lead vehicle has a fault, the follower vehicle to which the first automatic neutral section passing device without a fault belongs is determined as the target follower vehicle along the running direction of the double-heading marshalling train according to the result of whether each automatic neutral section passing device has a fault.

[0055] S3, determining a first distance between the master control vehicle and the phase-advance point when the master control vehicle receives a target phase-sensing signal corresponding to a target slave control vehicle based on a product of a position sequence number of the target slave control vehicle and a preset vehicle length.

[0056] wherein the position sequence number of each slave control vehicle is sequentially increased from the head of the re-connection marshalling train. Specifically, the position sequence number of the first slave control vehicle is 1, the position sequence number of the second slave control vehicle is 2, the position sequence number of the third slave control vehicle is 3, and so on, and the position sequence number of the Nth slave control vehicle is N, where N represents the total number of slave control vehicles in the re-connection marshalling train.

[0057] The preset vehicle length is the vehicle length of the slave control vehicle and the master control vehicle, and the preset vehicle length of the slave control vehicle and the master control vehicle is consistent.

[0058] The target phase-sensing signal is a phase-sensing signal collected by an automatic phase-over device of the target slave control vehicle when the target slave control vehicle passes through the phase-advance point. Further, the target slave control vehicle collects the target phase-sensing signal and sends the target phase-sensing signal to the master control vehicle and each slave control vehicle through a train gateway.

[0059] The phase-advance point is used to prompt the re-connection marshalling train to approach the phase-over area. When the re-connection marshalling train reaches the phase-advance point, the re-connection marshalling train can prepare to cut off the automatic phase-over function in advance, so as to timely cut off the automatic phase-over function of the re-connection marshalling train.

[0060] The first distance refers to the distance between the master control vehicle and the phase-advance point when the master control vehicle receives the target phase-sensing signal corresponding to the target slave control vehicle. When the automatic phase-over device of the target slave control vehicle collects the target phase-sensing signal and sends it to the master control vehicle, the master control vehicle has already driven away from the phase-advance point. Therefore, the first distance of the master control vehicle relative to the phase-advance point at this time needs to be inversely deduced according to the position of the target slave control vehicle.

[0061] S4, determining a second distance between the master control vehicle and a phase-over strong break point when the master control vehicle receives the target phase-sensing signal based on a difference between the preset phase-over distance and the first distance, and cutting off the automatic phase-over function of the re-connection marshalling train when the second distance is less than a preset safety distance.

[0062] wherein the preset phase-over distance refers to a fixed distance from the phase-advance point to the phase-over strong break point. The phase-over strong break point is a physical isolation point set on the electrified railway overhead contact system, which is used to forcibly cut off the master circuit breaker of the re-connection marshalling train, so as to safely pass through the phase-over area between different power supply sub-areas. For example, taking the slave control vehicle 2 as the target slave control vehicle, and using the phase-sensing signal of the slave control vehicle 2 and the slave control vehicle 2 to calculate the second distance, a schematic diagram is shown in Figure 3 .

[0063] The second distance is the distance between the master vehicle and the strong break point of the phase when the master vehicle receives the target phase signal. The preset safety distance is the minimum distance required from the position where the master circuit breaker of the re-connection marshalling train needs to start the power-off operation to the strong break point of the phase. The preset safety distance is preset to ensure that the re-connection marshalling train has sufficient time and space to complete the automatic phase-over function cut-off operation.

[0064] The automatic phase-over function refers to the function that the train can automatically complete the process of opening and closing the main circuit breaker when passing through the electric phase separation area of the catenary to ensure safe passage through the phase separation area.

[0065] In some embodiments, the automatic phase-over device collects the phase signal in real time and sends the collected phase signal to the master vehicle, so as to determine the target slave vehicle in real time and calculate the first distance based on the product of the position sequence number of the target slave vehicle and the preset train length, determine the second distance based on the difference between the preset phase distance and the first distance, so as to timely cut off the automatic phase-over function of the re-connection marshalling train when the second distance is less than the preset safety distance.

[0066] The above train phase-over redundant control method determines whether each automatic phase-over device has a fault, and sends the phase signal collected by each automatic phase-over device to the master vehicle and the slave vehicle. When the automatic phase-over detection device of the master vehicle has a fault, the first slave vehicle without a fault is determined as the target slave vehicle along the running direction of the re-connection marshalling train. The first distance between the master vehicle and the phase warning point when the master vehicle receives the target phase signal corresponding to the target slave vehicle is determined based on the product of the position sequence number of the target slave vehicle and the preset train length. In this way, the redundancy of the phase signal of the slave vehicle can be realized, and the availability of the automatic phase-over function can be improved. The second distance between the master vehicle and the strong break point of the phase when the master vehicle receives the target phase signal is determined based on the difference between the preset phase distance and the first distance. When the second distance is less than the preset safety distance, the automatic phase-over function of the re-connection marshalling train is cut off. In this way, the redundancy of the automatic phase-over function of the train can be fully utilized, and the re-connection marshalling train can be prevented from entering the phase area with power.

[0067] In one embodiment, step S1 comprises:

[0068] The state information of the automatic phase-over device of the master vehicle and the slave vehicle is sent to the train gateway.

[0069] The train gateway sends each state information to the master vehicle and the slave vehicle to determine whether the master vehicle has a fault according to each state information, and to determine the slave train to which the first automatic phase-over device without a fault belongs when the automatic phase-over detection device of the master vehicle has a fault.

[0070] The phase-splitting signals collected by each automatic neutral section device are sent to the master vehicle and the slave vehicle through the train gateway.

[0071] The state information of the automatic neutral section device of the master vehicle and the slave vehicle includes, but is not limited to, whether the automatic neutral section device has a fault, and a fault type of the automatic neutral section device. Further, the fault type of the automatic neutral section device includes a power disconnection.

[0072] In a specific application scenario, a schematic diagram of sending and receiving the phase-splitting signals is shown in FIG. 2. Figure 4 Specifically, the master vehicle and the slave vehicle send the phase-splitting signals of the ground magnetic induction coil detected by the automatic neutral section device to the central control unit, the central control unit sends the phase-splitting signals to the train gateway through network communication, and the train gateway forwards the phase-splitting signals to the full-reconnection marshalling train. When the master vehicle is fault-free, the phase-splitting signal of the master vehicle is preferred; when the master vehicle is faulty and the slave vehicle 1 is fault-free, the phase-splitting signal of the slave vehicle 1 is selected; when the master vehicle and the slave vehicle 1 are faulty, the target phase-splitting signal of the subsequent normal target slave vehicle is selected in turn. The master vehicle further includes a display screen, through which the preset safety distance setting and the automatic neutral section function removal can be performed.

[0073] In this embodiment, the state information of the automatic neutral section device of the master vehicle and the slave vehicle is sent to the train gateway, and the train gateway sends each state information to the master vehicle and the slave vehicle, so that whether the master vehicle has a fault can be determined according to each state information, and when the automatic neutral section detection device of the master vehicle has a fault, the slave train to which the first fault-free automatic neutral section device belongs can be determined. The phase-splitting signals collected by each automatic neutral section device are sent to the master vehicle and the slave vehicle through the train gateway, so that the transmission rate of the phase-splitting signals can be improved, so that the master vehicle can quickly receive the phase-splitting signals.

[0074] In one embodiment, the automatic neutral section function removal of the reconnection marshalling train in step S4 includes:

[0075] Outputting prompt information to prompt the operator to manually remove the automatic neutral section function through the prompt information.

[0076] The prompt information is information for prompting the operator to manually cut off the automatic overlap function. The form of the prompt information includes but is not limited to sound, light, and text. Further, when the second distance is less than the preset safe distance, text information is displayed on the display screen to prompt the operator to manually cut off the automatic overlap function. The displayed text information includes but is not limited to the second distance, and the size between the second distance and the preset safe distance. Further, the operator is prompted to manually cut off the automatic overlap function through the indicator light. For example, the operator is prompted to manually cut off the automatic overlap function through a red indicator light, and the operator is prompted to manually cut off the automatic overlap function by controlling the indicator light to flash.

[0077] In this embodiment, the operator is prompted to manually cut off the automatic overlap function by outputting the prompt information. This can timely cut off the automatic overlap function of the re-connection train when the re-connection train approaches the overlap strong breakpoint.

[0078] In one embodiment, the main circuit breaker is opened after the main control car receives the target overlap signal. After step S4, the method further includes:

[0079] S5, determining the running distance of the main control car after receiving the target overlap signal. When the running distance is greater than the preset running distance and the network voltage is in the normal range, the main circuit breaker is closed.

[0080] The running distance s of the main control car after receiving the target overlap signal can be calculated according to the driving time t, the driving speed v, and the acceleration a of the main control car through the formula The driving speed v is the speed of the main control car when it receives the target overlap signal. The running distance of the main control car after receiving the target overlap signal is also the running distance of the re-connection train.

[0081] The main circuit breaker is a key high-voltage electrical device on an electric locomotive or a motor train unit in an electrified railway system. The main function of the main circuit breaker is to open and close, protect, and isolate the high-voltage circuit of the re-connection train. The network voltage refers to the overhead line voltage.

[0082] In some embodiments, when the running distance is greater than the preset running distance, an overlap end signal is sent to the re-connection train to close the main circuit breaker based on the overlap end signal.

[0083] In some embodiments, the target phase signal includes a target phase pre-warning signal and a target phase strong breaking signal. After the master vehicle receives the target phase pre-warning signal, the master vehicle breaks the main circuit breaker after a preset waiting time. After the master vehicle receives the target phase breaking signal, if the main circuit breaker is not broken, the master vehicle directly breaks the main circuit breaker. The target phase pre-warning signal is a phase signal collected by the target slave vehicle when passing through the phase pre-warning point. The target phase strong breaking signal is a phase signal collected by the target slave vehicle when passing through the phase strong breaking point.

[0084] In this embodiment, by determining the running distance of the master vehicle after receiving the target phase signal, when the running distance is greater than the preset running distance and the network voltage is in the normal range, the main circuit breaker is closed. In this way, it can be ensured that the main circuit breaker is closed only when the re-connection marshalling train has completely driven out of the phase area, thereby avoiding the safety hazards caused by misoperation.

[0085] In one embodiment, after the master vehicle receives the target phase signal, the main circuit breaker is broken, and step S4 further includes:

[0086] S7, after the master vehicle receives the target phase signal, detecting the voltage provided by the overhead contact line to the re-connection marshalling train, when the voltage is in the preset voltage interval and the time length of the voltage being in the preset voltage interval is greater than the preset time length, the main circuit breaker is closed.

[0087] During the phase passing process, if the network voltage of a certain phase area does not interrupt due to high induced network voltage and other problems, the re-connection marshalling train cannot automatically close the main circuit, and the driver needs to manually operate the main circuit breaker to manually close the main circuit. This may cause the vehicle to not close the main circuit in time, resulting in long power loss time. This situation may cause the train to stop when the re-connection marshalling train is on an uphill.

[0088] The overhead contact line is a power transmission facility in an electrified railway system that provides power to electric locomotives or multiple units. The overhead contact line is composed of a series of wires suspended above the track, which directly contact the power reception device on the top of the train, thereby providing continuous power supply to the re-connection marshalling train.

[0089] The preset voltage interval is an interval condition for judging whether the voltage on the overhead contact line has recovered. Specifically, when the voltage on the overhead contact line is higher than 17500V and lower than 31000V for more than 2.5s, it is considered that the network voltage has recovered, and the main circuit breaker can be closed. When the voltage on the overhead contact line is lower than 15000V or higher than 32000V for more than 500ms, it is considered that the network voltage has interrupted, which indicates that the re-connection marshalling train has not driven out of the phase area, and the main circuit breaker cannot be closed. The network voltage refers to the voltage on the overhead contact line.

[0090] In some embodiments, when the voltage is in the preset voltage interval and the duration of the voltage being in the preset voltage interval is greater than the preset duration, a phase separation end signal is sent to the re-formation train to close the main circuit breaker based on the phase separation end signal.

[0091] In the embodiment, after the main control vehicle receives the target phase separation signal, the voltage provided by the overhead line system to the re-formation train is detected, and when the voltage is in the preset voltage interval and the duration of the voltage being in the preset voltage interval is greater than the preset duration, the main circuit breaker is closed. In this way, it can be ensured that the main circuit breaker is closed only when the re-formation train has completely left the phase separation area, thereby avoiding safety hazards caused by misoperation.

[0092] In one embodiment, the opening mode of the main circuit breaker includes automatic opening and / or manual opening, and the closing mode of the main circuit breaker includes automatic closing and / or manual closing, thereby increasing the flexibility of operation.

[0093] It should be understood that, although each step in the flowchart involved in each of the above-described embodiments is shown in sequence according to the arrow, these steps are not necessarily executed in the order indicated by the arrow. Unless otherwise specified herein, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other orders. Moreover, at least part of the steps in the flowchart involved in each of the above-described embodiments can include multiple steps or stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution sequence of these steps or stages is not necessarily sequential, but can be executed alternately or alternately with at least part of other steps or stages.

[0094] Based on the same inventive concept, the embodiments of the present application also provide a train phase separation redundancy control system for implementing the above-mentioned train phase separation redundancy control method. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme described in the above method, so the specific limitations in one or more train phase separation redundancy control system embodiments provided below can refer to the limitations of the train phase separation redundancy control method described above, which will not be repeated here.

[0095] In one embodiment, as shown in Figure 5 a train phase separation redundancy control system is provided, the re-formation train includes a main control vehicle and at least one slave control vehicle, the main control vehicle and the slave control vehicle are both loaded with an automatic phase separation device for collecting a phase separation signal, and the system includes:
