Description

Unmanned system of maglev train

Technical Field

The invention relates to an unmanned technology of a normally-conducting high-speed maglev train, in particular to an unmanned system of a maglev train and an unmanned method of the maglev train.

Background

The high-speed magnetic suspension train runs above the rails in a suspension mode. Because the vehicle is not contacted with the rail, the maglev train can not only reach the running speed of more than 500 kilometers per hour, but also has no noise, and has no wheel pair abrasion caused by wheel-rail friction, thereby greatly reducing the maintenance workload and the operation cost. In order to realize the efficient operation of high-speed maglev trains, a fully unmanned control system is urgently needed in the field for automatically controlling maglev trains and ground equipment on maglev lines.

The existing train unmanned control system is mainly applied to locomotives, and a traction and braking system of the existing train unmanned control system is configured on a vehicle. Accordingly, existing train drone control systems are primarily concerned with controlling the onboard traction and braking systems of a single train. However, the traction power supply system of the normally conducting high-speed magnetic levitation system is arranged beside the track, different traction control partitions are divided according to the track, one traction partition corresponds to one traction system, one traction partition only allows one train to run, and traction force and braking force according with the running direction are given through stator segments arranged on the track line. Therefore, the architecture of the existing unmanned system cannot be applied to a high-speed magnetic levitation system. The unmanned technology of the normal-conducting high-speed magnetic-levitation train in the field is still in a blank stage.

In order to make up for the technical defects in the field, the invention provides an unmanned technology of a maglev train, which utilizes equipment configured at multiple ends, such as a central control center, a vehicle-mounted equipment system, a station/vehicle base system, a communication transmission network, a traction power supply system, a track and the like to realize unmanned control of the maglev train.

Detailed Description

The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure. While the invention will be described in connection with the preferred embodiments, there is no intent to limit its features to those embodiments. On the contrary, the invention is described in connection with the embodiments for the purpose of covering alternatives or modifications that may be extended based on the claims of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The invention may be practiced without these particulars. Moreover, some of the specific details have been omitted from the description in order not to obscure or obscure the focus of the present invention.

As described above, the conventional train unmanned control system mainly relates to control of an on-board traction system and a brake system of a single train. However, the power system of the normally conducting high-speed magnetic levitation system is on the ground, and traction force and braking force according to the running direction are given through the stator segments arranged on the track line. Therefore, the existing unmanned system structure cannot be applied to the high-speed magnetic levitation system. The unmanned technology of the normal-conducting high-speed magnetic-levitation train in the field is still in a blank stage.

In order to make up for the technical defects in the field, the invention provides an unmanned system of a magnetic-levitation train, an unmanned method of a magnetic-levitation train and a computer readable storage medium, which utilize a central control center, a vehicle-mounted equipment system, a station/vehicle base system, a communication transmission network, a traction power supply system, a track and other equipment configured on the ground, the vehicle and a central control end to realize unmanned control of the magnetic-levitation train.

Referring to fig. 1, fig. 1 shows a schematic layout of an unmanned system of a magnetic-levitation train according to some embodiments of the present invention.

As shown in fig. 1, in some embodiments of the present invention, the unmanned system of a normally-conducting maglev train may include an operation control system, a traction power supply system, and a broadcasting system (PA), a Passenger Information System (PIS), a video monitoring system (IMS), an automatic fare collection system (AFC), an environment and equipment monitoring system (BAS), and a fire automatic alarm system (FAS) that implement an operation assistance function. Each system can be arranged on a central control center, a station, a vehicle and a track along the line according to actual application requirements so as to realize the dispatching and driving control of the magnetic-levitation train.

Specifically, the operation control system may include an operation scheduling system, an operation zone control system 12, a switch control system 13, a sleep wakeup unit 14, a Vehicle Safety Control (VSC) system 15, and an operation control transmission network 16, so as to schedule and control the unmanned operation of each train on the magnetic levitation train.

Further, the operation scheduling system may include a central scheduling unit 111 and a plurality of station scheduling units 112. The central scheduling unit 111 is configured in the central control center and is used for performing overall ground line scheduling and time scheduling on the magnetic-levitation train on the magnetic-levitation line. The station dispatching units 112 are respectively configured in the station control centers of the stations on the positive line of the magnetic suspension line, only have partial functions of the central dispatching unit 111, and are mainly used for carrying out local line dispatching on the magnetic suspension train in the local traction subarea when the central dispatching unit 111 has communication or operation faults.

The operation zone control system 12 is configured in the station control center of each station, and is configured to formulate a wake-up instruction according to the scheduling instruction formulated by the operation scheduling system to wake up the corresponding maglev train located in the traction zone, formulate a turnout adjustment instruction to adjust the position of the turnout, and formulate a start-stop instruction to control the traction power supply system to control the traction power supply of the maglev train. Correspondingly, the switch control system 13 is also configured in the station control center, and is used for pulling the position of the switch according to the switch adjustment command formulated by the operation zone control system 12 of the traction zone, so as to adjust the route of the magnetic-levitation train. The dormancy wakeup unit 14 is configured on the magnetic levitation train, powered by a vehicle-mounted uninterruptible power supply to keep running, and configured to wake up the corresponding magnetic levitation train to be powered on according to a wakeup instruction formulated by the running partition control system 12.

The vehicle-mounted safety control system 15 is configured on the magnetic-levitation train, and is used for performing self-checking on the magnetic-levitation train to obtain train self-checking information, and monitoring the magnetic-levitation train in real time to obtain train operation information. In some embodiments, the vehicle-mounted safety control system 15 may be connected to the vehicle-mounted speed measuring unit and the obstacle detecting unit through a vehicle network, and is adapted to monitor the running speed of the maglev train and the obstacle information in front of the maglev train by using the speed measuring unit and the obstacle detecting unit, and control the braking system of the maglev train to apply safety braking to the train according to the measured running speed and the obstacle information.

The operation control transmission network 16 includes a wired transmission network 161 and a wireless transmission network 162, and is used for connecting devices distributed on the ground, the vehicle, the central control center and the like in a communication manner to realize unmanned control of the magnetic suspension train. Referring to fig. 2, fig. 2 is a schematic diagram illustrating a communication connection relationship of an operation control system according to some embodiments of the present invention. As shown in fig. 2, in some embodiments, the ground devices of the operation control system and the traction power supply system may be communicatively connected through a wired transmission network 161 to complete information interaction between the ground devices of the central control end and the station end. On the contrary, the vehicle-mounted device of the maglev train can be communicatively connected to the ground devices of the central control end and the train station end through the wireless transmission network 162, so as to complete information interaction between the vehicle-mounted device and the ground device.

The working principle of the unmanned system will be described below in connection with the control flow of some unmanned systems. It will be appreciated by those skilled in the art that the control flow for such an unmanned system is only a few non-limiting embodiments provided by the present invention, and is intended to clearly demonstrate the broad concepts of the invention and provide specific details for enabling the public to practice the invention, and not to limit the scope of the invention.

Referring to fig. 3, fig. 3 is a schematic diagram illustrating a data flow of an operation control system according to some embodiments of the invention.

As shown in fig. 3, in some embodiments of the present invention, before the maglev starts to operate, the central dispatching unit 111 disposed in the central control center may first perform route dispatching with auto-route arrangement on the multiple maglev trains on the maglev train according to the schedule of the current day and the train plan. Thereafter, the central scheduling unit 111 may send a line scheduling command indicating train scheduling and start information to the operation zone control system 12 of each corresponding traction zone through the wired transmission network 161.

After receiving the line scheduling instruction, the operation partition control system 12 of each traction partition may send a wake-up instruction to the sleep wake-up unit 14 of the corresponding maglev train in the traction partition through the wireless transmission network 162 according to the scheduling instruction formulated by the central scheduling unit 111, so as to wake up the maglev train for powering on and self-checking. In response to the wake-up command, the sleep wake-up unit 14 may perform low-voltage power-up on the magnetic-levitation train to wake up the magnetic-levitation train for self-test. The vehicle-mounted safety control system 15 can start to work in response to the electrification of the maglev train, acquire train self-checking information of the maglev train, and send the acquired train self-checking information to the operation zone control system 12 of the traction zone through the wireless transmission network 162. Then, the operation zone control system 12 may send the received train self-check information to the central dispatching unit 111 and the station dispatching unit 112 of the local traction zone through the wired transmission network 161, so as to provide the operation dispatching system with reference and dispatching adjustment.

If the train self-checking information indicates that the self-checking of the magnetic-levitation train is normal, the central dispatching unit 111 can arrange a route for the corresponding magnetic-levitation train according to the train self-checking information. Specifically, the central scheduling unit 111 may send the route scheduling instruction of the maglev trains which are normally checked to the operation zone control systems 12 of the plurality of traction zones according to the current time schedule, the train schedule, and the train self-check information of each maglev train. In response to the line dispatching command, the operation zone control system 12 of each traction zone may send a switch adjustment command to the switch control system 13 of the traction zone through the wired transmission network 161 to pull the position of the switch and lock the route of the magnetic-levitation train. Then, the operation zone control system 12 of each traction zone can send a start-stop instruction to the traction power supply system of the traction zone through the wired transmission network 161 to supply power to the power device laid at the designated position of the magnetic suspension line to drive the magnetic suspension train to operate.

In the running process of the magnetic-levitation train, the vehicle-mounted safety control system 15 can monitor train running information of the magnetic-levitation train through interfaces such as a vehicle-mounted position sensor, a speed measurement unit and a door control unit. The train operation information includes, but is not limited to, at least one of a train position, a travel speed, a door status, and a safety braking status. Because the normal conducting high-speed maglev needs a corresponding power track to supply power when running at low speed, the maglev train must stop in a parking area with the power track when running on a positive line, so as to avoid that the maglev train stopped in a non-electric area can not be started. In some embodiments, the onboard safety control system 15 can determine whether the magnetic-levitation train is in a safe state according to the monitored train operation information. For example, if the running speed of the maglev train is greater than the specified train speed limit, the on-board safety control system 15 may determine that the maglev train is in an unsafe state of speed. If the estimated stopping point of the maglev train is located outside the stopping area (i.e. the area where the power track is not laid), the vehicle-mounted safety control system 15 can determine that the maglev train is in the unsafe state of position. In response to determining that the maglev train is in an unsafe state, the on-board safety control system 15 may trigger a traction cutoff and apply eddy current braking to the maglev train to avoid further safety accidents caused by these unsafe states.

It will be appreciated by those skilled in the art that the above-described unsafe conditions of speed and position are merely non-limiting examples provided by the present invention, and are intended to clearly illustrate the scope of the invention and provide specific solutions to the public for implementation without limiting the scope of the invention. Optionally, in other embodiments, the vehicle-mounted safety control system 15 may further determine a corresponding non-safety state according to other train operation information, and execute a corresponding safety protection measure, so as to achieve the effect of improving the train safety as well.

After obtaining the train operation information of the maglev train, the vehicle-mounted safety control system 15 may send the monitored train operation information to the integrated monitoring system configured in the central control center through the operation zone control system 12 of the traction zone where the train is located, so that the central scheduling unit 111 monitors and tracks the trains on the maglev line. In some embodiments, the central scheduling unit 111 may determine the deviation of each train from the schedule based on the results of train monitoring and tracking. Then, the central scheduling unit 111 can adjust the schedule according to the deviation of each train from the schedule, and formulate a time scheduling instruction for automatic train adjustment to schedule the time of the magnetic levitation train.

In some embodiments, when the central dispatching unit 111 fails to dispatch the whole magnetic-levitation train due to a communication failure or an operation failure, the station dispatching unit 112 disposed at each station can dispatch the multiple magnetic-levitation trains located in the local towing sector according to the schedule of the local towing sector and the train plan. Thereafter, the station dispatching unit 112 may send a line dispatching command indicating train shift and start information to the operation zone control system 12 of the local traction zone through the wired transmission network 161 to route the corresponding magnetic-levitation train. In some embodiments, the control priority of the central scheduling unit 111 is higher than that of the station scheduling units 112, and the control priorities of the station scheduling units 112 are the same. The station dispatching units 112 with the same control priority only have the function of performing route dispatching such as automatic route arrangement on the magnetic-levitation trains in the traction subarea, but do not have the function of performing schedule adjustment and train automatic adjustment on all the magnetic-levitation trains on the magnetic-levitation route.

As shown in fig. 1, in some embodiments of the present invention, the station dispatching unit 112 may also be configured in a control center of the vehicle base. Unlike a station configured with a positive line, a vehicle base can be configured with the track line of a magnetic levitation line. The station dispatching unit 112 disposed at the vehicle base is adapted to make dispatching instructions for storage management, vehicle maintenance and car washing for the magnetic-levitation train parked at the vehicle base, and to perform route dispatching for the magnetic-levitation train parked at the vehicle base according to the current day schedule and the train plan. In some embodiments, the station dispatching unit 112 configured at the vehicle base is further adapted to communicate with the central dispatching unit 111 to obtain the route dispatching plan formulated by the central dispatching unit 111, so as to control the magnetic-levitation train at the vehicle base to switch to the main line running according to the route dispatching plan.

Referring to fig. 1 and 4 in combination, fig. 4 is a schematic diagram illustrating an architecture of a traction power supply system according to some embodiments of the present invention.

As shown in fig. 1 and 4, in some embodiments of the present invention, the traction power supply system may include a main substation, a traction substation 21, a trackside substation 22, and the like, and a traction zone control system 23 for providing traction and braking force to the maglev train to control the operation thereof.

The main substation and the traction substation 21 may be disposed at each station. The main substation is used for reducing the high voltage provided by the power system into the medium voltage required by the magnetic levitation system, and providing the medium voltage to the traction substation 21 and the trackside substation 22. The traction substation 21 is used to supply power to the traction zone control system.

The traction sub-area control system may be disposed at each station, and power is supplied from the traction substation 21 at the station. The traction subarea control system is suitable for controlling the trackside substation 22 to supply power to the power device arranged at the designated position of the magnetic suspension line according to the start-stop instruction sent by the running subarea control system 12 of the traction subarea.

The trackside substation 22 is disposed along the magnetic levitation train and adapted to supply power to a power device disposed at a designated position of the magnetic levitation train according to a control command of the traction zone control system of the traction zone to drive the magnetic levitation train at the designated position to operate.

Specifically, the traction zone control system may include a traction real-time monitoring system 231, a safety cut-off switch (not shown), a traction logic control system 232, a converter control unit 233, and a stator switching station 234. And the equipment in the same traction subarea and among different traction subareas realize information interaction through a traction control network.

The traction real-time monitoring system 231 is used for acquiring the state of the all-wire traction equipment and the state of the stator segment, and displaying the state information and the current and voltage information of the currently occupied stator segment of the train in real time according to the acquired train position information. In some embodiments, the real-time monitoring system 231 may be divided into two parts, a control center and a station. The monitoring device configured in the central control center can obtain the running information of the traction power supply system of the whole magnetic suspension line from each traction subarea, so that the central scheduling unit 111 can refer to and monitor the central scheduling. In some embodiments, the monitoring device configured in the central control center may further display the traction system condition of the entire magnetic suspension line through a large-screen human-machine interface of the central scheduling unit 111, so as to provide the operator of the central control center with reference and monitoring for central scheduling. In contrast, the monitoring device configured in the station control center may obtain the operation information of the traction power supply system of the local traction partition, and display the conditions of the traction power system in the area around the current station (i.e., the local traction partition) on the human-computer interface of the station scheduling unit 112, as a supplement to the overall monitoring of the control center.

The safety cut-off switch (not shown) is a safety switching device for cutting off a failed traction power. In some embodiments, each operation zone control system 12 may monitor the operation status of each power equipment in the traction power supply system of the local traction zone through the diagnostic maintenance network, and monitor the safety status of the magnetic-levitation train located in the local traction zone through the on-board safety control system 15. The power plant includes, but is not limited to, stator segments distributed along a magnetic levitation line. In response to determining that any stator segment is faulty or the maglev train is in a non-safe state of position and/or speed, the run zone control system 12 may control the corresponding safety cut-off switch to immediately cut off the input and output loops of the traction zone control system, and stop supplying power to the faulty stator segment to disable the power of the faulty stator segment, thereby preventing the faulty stator segment from driving the maglev train incorrectly.

The traction logic control system 232 may be communicatively connected to the operation zone control system 12 of the traction zone, and is adapted to obtain train self-checking information and train operation information provided by the vehicle-mounted safety control system 15, and start/stop instructions formulated by the operation zone control system 12, so as to determine a position corresponding to the maglev train and a given traction braking force to be provided to the maglev train.

The operation of the traction logic control system 232 will be described below in connection with the control flow of some traction power supply systems. It will be appreciated by those skilled in the art that the control flow of the unmanned system is only a non-limiting example provided by the present invention, and is intended to clearly illustrate the broad concepts of the invention and provide some detailed examples for facilitating the implementation by the public and not to limit the scope of the invention.

Referring to fig. 5, fig. 5 illustrates a schematic diagram of stator segment power supply control provided in accordance with some embodiments of the present invention.

As shown in fig. 5, in some embodiments of the present invention, the start-stop instructions specified by the zone control system 12 include, but are not limited to, one or more of a tow run instruction, a tow shut-off instruction, line data information, stop-point step information. The traction logic control system 232 can calculate to realize speed closed loop according to the train information and the start-stop instruction, and formulate a traction braking control strategy and a train speed control strategy of the maglev train. The traction logic control system 232 may then output the calculated traction brake apply force to the converter control unit 233 and send a switch on/off command to the corresponding stator switching station 234.

Specifically, the converter control unit 233 may include an input transformer, a converter power unit, an output transformer, an input/output switch cabinet, and the like. The converter control unit 233 is adapted to convert the dc power provided by the main converter into a three-phase ac power with variable frequency, phase and amplitude according to the traction braking given force provided by the traction logic control system 232, and provide the three-phase ac power to the stator segment where the train takes place on the line, so as to implement the traction braking control of the maglev train. In some preferred embodiments, the inverter control unit 233 may also collect the actual traction brake force output by the stator segments to achieve closed loop control of the traction brake force.

The stator switching station 234 may be disposed along the magnetic levitation line for controlling the plurality of stator segments at corresponding positions. The stator switching station 234 can control the working state of each stator section on the line by controlling the on-off of the switch according to the on-off instruction given by the traction logic control system 232, thereby realizing the traction braking control of the magnetic suspension train. In some embodiments, each stator segment may be supplied in segments. That is to say, each traction subarea only has a pair of stator sections to work and supply power to drive the magnetic suspension train at the corresponding position to run, thereby achieving the effects of saving energy and reducing the consumption of electric energy.

Furthermore, in order to reduce the line loss, the traction logic control system 232 and the converter control system 233 may be disposed at both ends of the operating region, and the devices at both ends of the traction subarea are switched according to the train information and the start-stop instruction, so as to realize the master-slave control in the same traction subarea and the subarea switching function between two traction subareas, thereby controlling the operation of the maglev train more efficiently.

As shown in fig. 1, in some embodiments of the invention, the central control center may also be configured with an integrated monitoring system 17. The integrated monitoring system 17 may be connected to each of the train-ground devices of the operation control system and the traction power supply system through an independent diagnosis and maintenance network, and may be connected to one or more of the broadcasting system (PA), the Passenger Information System (PIS), the video monitoring system (IMS), the automatic ticket selling and checking system, the environment and device monitoring system, and the automatic fire alarm system. The diagnostic maintenance network may include a wired transmission network 161 and a wireless transmission network 162. The central dispatching unit 111 and the dispatching personnel of the central control center are connected with the integrated monitoring system 17 through the IMS, PA, PIS and voice system, know the field situation in time through the wired transmission network 161 and the wireless transmission network 162, and make appropriate associated control decisions, thereby controlling the traction power supply system and each associated system, and completing the passenger transportation service according to the safe, efficient and on-time principle.

Specifically, in some embodiments, the station control center of each station may be configured with a personnel protection switch 18. Before driving the maglev train to approach and during the operation of the maglev train, each operating zone control system 12 can monitor whether a person enters the operating area of the maglev train. If someone enters the operation area of the maglev train, the operation zone control system 12 can turn off the personnel protection switch 18 of the traction zone to give personnel protection alarms. The operation scheduling system can monitor the state of the personnel protection switch 18 of each traction subarea in real time through the comprehensive monitoring system 17. In response to the opening of the personnel protection switch 18 of any traction zone, the operation dispatching system can set the corresponding traction zone as a fault area and cancel the route of each magnetic-levitation train in the fault area.

According to another aspect of the present invention, there is also provided herein a method of unmanned driving of a magnetic levitation train. The unmanned method is to control the running of the magnetic-levitation train by using the unmanned system of the magnetic-levitation train provided by any one of the embodiments.

The unmanned method of the magnetic levitation train described above will be described below in conjunction with some control methods of the unmanned system. It will be appreciated by those skilled in the art that these control methods for the unmanned system are only some non-limiting examples, which are intended to clearly demonstrate the main idea of the invention and to provide some detailed solutions for the implementation by the public, and not to limit the scope of protection of the invention.

Referring to fig. 6, fig. 6 illustrates a flowchart of a method for controlling an unmanned aerial vehicle according to some embodiments of the present invention.

As shown in fig. 6, in some embodiments of the present invention, a control method of an unmanned system may include the steps of: and testing the ground equipment and the vehicle-mounted equipment which are positioned in each traction subarea of the magnetic suspension line to be used as a scheduling basis.

Specifically, before the operation of the magnetic levitation system is started, the staff member of the central control center may first power on the central control center and import the operation plan of the whole magnetic levitation line to the central scheduling unit 111. The operation plan includes, but is not limited to, a time of day and a train utilization plan. Then, the central dispatching unit 111 may generate a planned operation chart of the current day at a predetermined time (e.g., 1-2 hours) before the magnetic levitation system is put into operation, and issue the plurality of partition operation plans to the station dispatching unit 112 of each related traction partition, and other related systems and stations via the wired transmission network 161.

After receiving the partition operation plan, the staff at each relevant station can Power on the operation Control system and the traction Power supply system in the station at a low voltage, and remotely Power on the operation interval equipment through a Power supervisory Control and Data Acquisition (PSCADA) system. Then, the operation zone control system 12 of each traction zone can detect whether the constructors in the traffic line area and the main line area in the traction zone are both clear, and confirm whether the relevant traveling equipment and power supply equipment meet the operation condition of the day.

In some embodiments, if there is a person in the yard or main area within the traction zone, the operating zone control system 12 may open the personnel protection switch 18 of the present traction zone to make a personnel protection alarm. The operation scheduling system can monitor the state of the personnel protection switch 18 of each traction subarea in real time through the comprehensive monitoring system 17. In response to the disconnection of the personnel protection switch 18 of any traction zone, the operation dispatching system can set the corresponding traction zone as a fault area and cancel the route of each maglev train in the fault area.

In some embodiments, in response to low voltage power up of the traction power supply system, the central dispatch unit 111 may send a traction state transition command over the wired transmission network 161 to transition its traction state to a corresponding test state. The traction power supply system can determine whether the stator sections distributed at various positions of the magnetic suspension line are electrified normally through links such as current test and the like, and determine whether the stator switches 234 are in normal contact. Then, the traction power supply system may feed back the current test result to the operation zone control system 12 of the traction zone, so that the central scheduling unit 111 determines whether each zone of the traction zone can normally operate according to the test result. In some embodiments, if the power loss caused by the failure of one traction partition exceeds the preset ratio threshold, the central scheduling unit 111 may determine that the state of the traction power supply system of the traction partition does not satisfy the operation condition, so as to first take the route arrangement of the demagnetized floating train in the failure area, and notify the maintenance personnel to perform the troubleshooting on the area. In some embodiments, the central dispatch unit 111 may also resume routing of the magnetic-levitation train in the section area to implement the section operation in response to the troubleshooting feedback of the failed area.

After completing the state tests of the personnel protection switch 18, the operation zone control system 12, the turnout control system 13 and the traction power supply system, the central dispatching unit 111 may perform high-voltage power-on operations on the vehicle base in the non-fault area and the traction power supply system of the main line according to the planned operation diagram. In some embodiments, the cameras of the corresponding area may be triggered before the high voltage power-on operation of the traction power supply system is performed, and the captured images are pushed to the station dispatching unit 112 for auxiliary confirmation by the dispatcher workstations. In some embodiments, a broadcast may also be triggered prior to performing a high voltage power-up operation of the traction power supply system to alert field personnel to prepare for power-up.

In some embodiments of the invention, the invention can also perform the train test of the magnetic-levitation train preferentially before the implementation of the access operation so as to ensure the safe operation of the magnetic-levitation train. Specifically, in response to receiving the partition operation plan, the station scheduling unit 112 of each vehicle base may first make a scheduling plan for entering and exiting the vehicle base according to the personnel scheduling situation of the local towing partition, the received partition plan operation diagram, the actual station occupation situation of the train in the vehicle base and the vehicle maintenance situation, and send the scheduling plan to the central scheduling unit 111 before the magnetic levitation system starts to operate. The central dispatching unit 111 can send the wake-up command to the sleeping wake-up unit 14 of the corresponding maglev train according to the schedule of entering and exiting the garage of each vehicle base.

In response to the wake-up command, the sleep wake-up unit 14 may wake up the corresponding magnetic-levitation train for low-voltage power-up. The magnetic-levitation train can automatically perform self-checking in response to low-voltage power-on. The Vehicle Safety Control (VSC) system 15 can obtain train self-check information of the maglev train and forward it to the operation zone control system 12 of the vehicle base control center. The station dispatching unit 112 can determine whether a train needs to be changed according to the fault condition of the magnetic-levitation train. In some embodiments, if the low-voltage powered maglev train has no fault and passes the self-test, the station dispatching unit 112 may send the maglev train passing the self-test to the central control center for the central dispatching unit 111 to dispatch integrally. On the contrary, if the low-voltage electrified magnetic suspension train fails to pass the self-test, the station dispatching unit 112 may select to replace the train and send the information related to the replaced train to the central control center for the central dispatching unit 111 to dispatch the train integrally.

As shown in fig. 6, in some embodiments of the present invention, the control method of the unmanned system may further include the steps of: and the central dispatching unit is used for carrying out line dispatching and time dispatching on the multiple rows of magnetic suspension trains on the magnetic suspension lines according to the operation plan of the magnetic suspension lines.

After the tests of the ground equipment and the vehicle-mounted equipment are completed, the central dispatching unit 111 can modify the imported operation plan so as to realize the overall line dispatching of the multiple lines of maglev trains on the maglev lines. Specifically, the central scheduling unit 111 may first issue a traction state transition command to the operating zone control system 12 of each corresponding traction zone, control the corresponding traction power supply system to close the power supply input switch to establish the intermediate voltage, and close the output switch in preparation for applying three-phase ac power to the stator segments to control train operation.

Then, the central dispatching unit 111 may send a control command to each garage door control module of each station control center to open the garage door, and perform automatic route arrangement on the multiple magnetic-levitation trains stored in each garage after receiving the feedback of the opening state of the garage door. The operation zone control system 12 may send a switch adjustment command to the switch control system 13 according to the automatic route arrangement of each maglev train to lock the corresponding route.

After the route transaction is completed, the central dispatching unit 111 may send an insert operation command to the magnetic-levitation train completing the self-check. The break in operation command may include the distance, speed and direction the train is allowed to travel. In response to receiving the plug-in running command, the on-board safety control system 15 may control the train to levitate. The central dispatching unit 111 can then also send an insert run command to the traction power supply system via the run zone control system 12 to control it to apply three-phase ac power to the stator segment where the maglev train is located, thereby generating a traveling wave magnetic field that controls the train's operation.

In some embodiments of the present invention, the operation control system needs to first determine the effective position of the maglev train before operation to realize the control. The vehicle base zone control system 12 may operate without power down. Before the maglev train runs formally, the traction subarea control system can determine the initial position of the maglev train through small current control. And then, the traction subarea control system can control the magnetic-levitation train to run through a ground absolute positioning mark according to the expected running direction of the train so as to obtain the actual position of the train and judge the actual running direction of the train. If the driving direction is inconsistent with the system convention, the operation zone control system 12 will force the maglev train to stop, and request the central dispatching unit 111 to insert the operation command containing the new direction, so as to control the maglev train to operate again. After the inserting operation, the magnetic suspension train obtains the correct positioning and direction. In some embodiments, the operation control system can also control the maglev train to run through one or more ground absolute marks, and correct the mileage recorded by the onboard safety control system 15 according to the mileage corresponding to the ground absolute mark, so as to correct the actual position of the maglev train. Then, the running control system can control the magnetic suspension train to run on the positive line of the magnetic suspension line according to the corrected position information.

Because the normal conducting high-speed maglev needs a corresponding power track to supply power when running at low speed, the maglev train must stop in a parking area with the power track when running on a positive line, so as to avoid that the maglev train stopped in a non-electric area can not be started.

In some embodiments of the invention, each traction zone may include a plurality of parking zones. These parking areas may be paved with stator segments (i.e. power tracks) for powering the magnetic-levitation train. In the process of running the maglev train on the main track, the running zone control system 12 can obtain the running speed of the maglev train from the vehicle-mounted safety control system 15, and determine a proper parking zone according to the running speed. Referring to fig. 7, fig. 7 illustrates a parking spot stepping diagram provided in accordance with some embodiments of the present invention.

As shown in fig. 7, in the above embodiment, each parking zone may correspond to one maximum speed curve and one minimum speed curve. These velocity (V) curves vary with the distance (S) of the maglev train to the ends of the parking area. The zonal control system 12 can compare the real-time position and the travel speed of the maglev train to the speed profile. In some embodiments, if the travel speed of the maglev train is greater than the minimum speed curve 2, the operation zone control system 12 can determine that the maglev train is sufficient to pass through the unpowered area and move to the next parking zone. On the contrary, if the running speed of the magnetic-levitation train is greater than the minimum speed curve 2, the operation zone control system 12 can determine that the magnetic-levitation train cannot pass through the unpowered area between the two parking zones, so as to control the magnetic-levitation train to park in the parking zone. Specifically, the operation zone control system 12 can calculate a specific stop point of the maglev train according to the real-time position and the running speed of the maglev train, and formulate corresponding stop point step information. Then, the operation zone control system 12 can send the established parking point stepping information to the traction power supply system to control the maglev train to step and stop in the parking area paved with the power track according to the parking point stepping information.

In some embodiments, the parking area may include a platform area of each station. When the maglev train stops at the platform, the vehicle-mounted safety control system 15 can control the maglev train to fall. Then, the magnetic suspension train can utilize the vehicle-mounted door control unit to open and close the vehicle door so as to provide the passengers with access at the platform.

In some embodiments, the in-vehicle safety control system 15 may also perform obstacle detection using an in-vehicle obstacle detection unit. In response to the anomaly in the obstacle detection result, the on-board safety control system 15 can immediately cut off the traction power supply of the traction power supply system and start eddy current braking to control the magnetic-levitation train to stop nearby.

In some embodiments, the central dispatching unit 111 can also utilize the onboard safety control system 15 of each maglev train to perform train monitoring and tracking on the train position and/or the running speed of each maglev train, and determine the deviation of the relative schedule of each maglev train according to the train monitoring and tracking result. Then, the central scheduling unit 111 can also adjust the schedule according to the deviation of each maglev train from the schedule, and formulate the time scheduling instruction for automatic train adjustment to perform time scheduling of the whole maglev line.

Further, the central control center may also be configured with an integrated monitoring system 17. The integrated monitoring system 17 may be connected to each of the train-ground devices of the operation control system and the traction power supply system through an independent diagnosis and maintenance network, and may be connected to one or more of the broadcasting system (PA), the Passenger Information System (PIS), the video monitoring system (IMS), the automatic ticket selling and checking system, the environment and device monitoring system, and the automatic fire alarm system. The diagnostic maintenance network may include a wired transmission network 161 and a wireless transmission network 162. The central dispatching unit 111 can be connected to the integrated monitoring system 17 through the IMS, PA, PIS, and voice systems, know the field situation in time through the wired transmission network 161 and the wireless transmission network 162, and make appropriate associated control decisions, thereby controlling the traction power supply system and each associated system, and completing the passenger transportation service according to the safe, efficient, and on-time principle. In some embodiments, the integrated monitoring system 17 may further display the collected device information of all the ground devices and all the vehicle-mounted devices on a display interface of the central control center, so that a dispatcher of the central control center can know the field situation in time and make an appropriate associated control decision. Then, the central scheduling unit 111 may adjust the originally formulated line scheduling and time scheduling according to a manual scheduling instruction input by a scheduling person through a human-computer interaction interface.

As shown in fig. 6, in some embodiments of the present invention, the control method of the unmanned system may further include the steps of: and responding to the fault of the central dispatching unit, and utilizing each station dispatching unit to carry out the line dispatching of the traction subarea on the magnetic suspension train positioned in the traction subarea according to the corresponding subarea operation plan.

Specifically, when the central scheduling unit 111 fails to perform the entire scheduling of the magnetic levitation train due to a communication failure or an operation failure, the station scheduling unit 112 disposed at each station can perform route scheduling of automatic route arrangement for the multiple magnetic levitation trains located in the local towing bay based on the schedule of the local towing bay and the train plan. Thereafter, the station dispatching unit 112 may send a line dispatching command indicating train shift and start information to the operation zone control system 12 of the local traction zone through the wired transmission network 161 to route the corresponding magnetic-levitation train. In some embodiments, the control priority of the central scheduling unit 111 is higher than that of the station scheduling units 112, and the control priorities of the station scheduling units 112 are the same. The station dispatching units 112 with the same control priority only have the function of performing route dispatching such as automatic route arrangement on the magnetic-levitation trains in the traction subarea, but do not have the function of performing schedule adjustment and train automatic adjustment on all the magnetic-levitation trains on the magnetic-levitation route.

In some embodiments, when the maglev system is finished operating, the central dispatching unit 111 may dispatch each maglev train to the vicinity of the corresponding vehicle base according to the operation plan of the next day. The station dispatching unit 112 of each vehicle base can perform the storage-returning route arrangement on the magnetic-levitation train in the traction subarea according to the corresponding subarea operation plan. Then, the station dispatching unit 112 of each vehicle base can utilize the running zone control system 12 of the present traction zone to control the traction power supply system to drive the magnetic-levitation train to step back to the base.

In some embodiments, the station dispatching unit 112 configured at the vehicle base may also have a function of automatically arranging a car wash route and a maintenance route. Specifically, the station dispatching unit 112 of each vehicle base can perform the car washing route arrangement and the maintenance route arrangement according to the car washing requirement and the maintenance requirement of each magnetic-levitation train located in the local traction subarea. Then, the station dispatching unit 112 can utilize the operation zone control system 12 of the traction zone to control the traction power supply system to drive each maglev train to step to the corresponding car washing point and maintenance point respectively for automatic car washing and automatic maintenance.
