Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The train route transaction method and apparatus of the present invention will be described with reference to fig. 1-5.

As shown in fig. 1, the present invention provides a train route handling method, which includes: as follows from step 110 to step 150.

In step 110, train position information is obtained, and front train position information is obtained from the trackside control unit.

It can be understood that the execution subject of the train route transaction method can be an on-board control system of the train, as shown in fig. 2, the on-board control system is used for controlling signal transmission of the train, and the on-board control system can have an overspeed protection function, a route control function, a mobile authorization calculation function and an electronic map management function. The vehicle-mounted manager is a logic control center of the train, the vehicle-mounted manager can be in communication connection with the train positioning device and can acquire the train position information, and the vehicle-mounted control system can acquire the train position information from the vehicle-mounted manager.

As shown in fig. 2, a trackside control unit (OC)₁To OC_n) The trackside control unit can control the actuating elements on the track, such as the working states of a signal machine and a turnout. The dispatching command system is used for commanding and dispatching the running processes of a plurality of trains.

It should be noted that, when each train passes through the trackside control unit, the trackside control unit registers and records information of the train, and meanwhile, the subsequent driving process of the train can be tracked, and the position of the train can be obtained in real time.

And step 120, determining a route section based on the train position information and the front signal position information.

It can be understood that the position information of the front signal is the position information of the nearest signal in front of the train, the signal is the trackside basic equipment of railway and urban rail transit, the railway signal system takes the ground signal as the main signal, and the driver must operate according to the display of the signal; the urban rail transit takes a vehicle-mounted signal as a main signal, a signal machine is not arranged in a main line section basically, and a ground signal machine is arranged only in a turnout section for the requirement of shunting operation.

The position and the quantity of the signal machines arranged on the track can be determined, the position of the signal machine can be prestored in the vehicle-mounted control system, after the train operation plan is determined, the vehicle-mounted control system can determine the positions of a plurality of signal machines corresponding to the train operation plan, and meanwhile, the position information of the front signal machine of the train can be found according to the train position information.

The route section of the train may be determined based on the train position information and the front traffic signal position information, because the current position of the train is used as the starting point and the position of the front traffic signal is used as the ending point.

And step 130, if the turnout exists in the route section, judging whether the opening direction of the turnout is consistent with the train advancing path.

It will be appreciated that the access section comprises a section of track on which there may be switches, a type of line connection device that allows a rolling stock to switch from one track to another, switches being important devices for effecting track changes and being widely present on railway lines. The common switch types include single switch, three switch, cross switch and crossover switch.

If a turnout exists in a route section of a train, the train can normally run, the opening direction of the turnout needs to be ensured to be consistent with the train running path, otherwise, safety accidents are possible to occur, and here, the vehicle-mounted control system can acquire the opening direction of the turnout through a trackside control unit, compare the opening direction of the turnout with the train running path and judge whether the opening direction of the turnout is consistent with the train running path or not; of course, the on-board control system may also pre-store the opening direction of the switch in the route section, or determine the opening direction of the switch in the route section according to the train operation plan.

And step 140, if the opening direction of the turnout is not consistent with the train advancing path and the turnout is not locked, sending turnout control information to the trackside control unit so as to change the opening direction of the turnout to be consistent with the train advancing path.

It will be appreciated that if the switch is not open to the same direction as the train path of travel within the route section of the train, there may be two situations:

in the first case, the switch is not locked by other routes, the on-board control system may send switch control information to the trackside control unit, adjusting the direction of the switch to be consistent with the train travel path.

In the second case, the turnout is locked by other routes, and the vehicle-mounted control system can wait for the turnout to be unlocked and then send turnout control information to the trackside control unit, so that the turnout is changed to be consistent with the train travelling path.

In other words, the train route transaction method further includes: if the opening direction of the turnout is not consistent with the train advancing path and the turnout is locked, after the turnout is unlocked, turnout control information is sent to the trackside control unit, so that the opening direction of the turnout is changed to be consistent with the train advancing path.

Of course, if the direction of the switch is the same as the train route in the route section of the train, no separate adjustment is necessary, and if there is no switch in the route section of the train, no separate adjustment is necessary.

And 150, under the conditions that the train does not exceed the position of the front train in the advancing process and the opening direction of the turnout is consistent with the advancing path of the train based on the train position information and the front train position information, the train is transacted.

It can be understood that there are two basic prerequisites for handling the route for the train, one is to control the position of the train not to exceed the front train in the process of traveling, so that the train will not collide with the front train, and the other is to make the direction of the turnout consistent with the traveling path of the train.

If the physical parameters of the train, such as the running direction, the running speed, the running acceleration and the like, accord with the two basic premises, the train can be transacted.

As shown in fig. 3, in one possible embodiment, it is determined whether the train operation plan is valid, if yes, it is determined whether the front traffic signal is normal, if yes, it is determined whether there is a switch in the route section, if not, the route transaction is successful, if yes, it is determined whether the opening direction of the switch is consistent with the train traveling path, if yes, the route transaction is successful, if no, it is determined whether the switch is locked, if yes, the route transaction is failed, if no, the switch is controlled to turn, it is determined whether the adjusted opening direction of the switch is consistent with the train traveling path, if yes, the route transaction is successful, and if no, the route transaction is failed. It should be noted that the route transaction failure shown in fig. 3 refers to the failure of this route transaction, and does not mean that the route transaction is not attempted any more, for example, after the switch is unlocked, the switch may be controlled to turn again, and then the route transaction is performed. In addition, the route handling here is the route handling for the train mentioned above.

It is worth noting that the current CBTC system is composed of an integrated monitoring center (ATS), a vehicle-mounted controller (VOBC), a Zone Controller (ZC), and a Computer Interlock (CI). The route control process is as follows: the central ATS issues a train plan; the station ATS generates an access sequence and issues an access control command to the computer interlocking device in due time; the computer interlocking equipment controls the access to be opened; and the vehicle-mounted equipment passes through the train route according to the driving permission. This is a kind of "vehicle-ground-vehicle" communication architecture, and the control process is relatively complicated.

The invention breaks through the communication architecture of the traditional CBTC system 'vehicle-ground-vehicle', and adopts the communication architecture of 'vehicle-vehicle'. Compared with the traditional CBTC system, the system simplifies the traditional ground equipment such as ZC, CI and the like. The train-mounted control system bears the functions of route control, route protection and the like of the traditional ground interlocking, controls the trackside equipment through the trackside control unit, is different from the traditional ground interlocking route handling mode, breaks through the route handling mode from the signal machine to the signal machine in the traditional CBTC signal system when handling the route, and adopts the route handling mode taking the train as the center in the train operation control system based on the 'train-vehicle' communication, namely, takes the position of the train as the starting point and takes the signal machine as the terminal point to handle the route; meanwhile, the vehicle-mounted equipment also has the functions of mobile authorization calculation and the like of the traditional ZC, so that the efficiency of the whole system is greatly improved.

It is worth noting that the method uses the train as the center to transact the route, and compared with the method using other equipment as the center to transact the route, the method can simplify the process of transacting the route.

The train route transaction method provided by the invention has the advantages that the route transaction operation is performed by taking the train as the center, the position of the train which does not exceed the front train is confirmed in the route section by the vehicle-mounted control system, and the opening direction of the turnout is consistent with the advancing path of the train under the condition that the turnout exists, so that the route transaction process is simple and convenient, and the work efficiency of the route transaction is improved.

In some embodiments, the obtaining the position information of the leading vehicle from the trackside control unit in step 110 includes: confirming whether the train enters the jurisdiction of the trackside control unit or not based on the train position information and the jurisdiction information of the trackside control unit; if the train enters the jurisdiction range of the trackside control unit, the train and the trackside control unit are registered, and historical registered train information sent by the trackside control unit is received; and confirming the position information of the previous train based on the train position information and the history registered train information.

It can be understood that each trackside control unit has a certain jurisdiction, the jurisdiction information of the trackside control unit is used for representing a certain interval range on a track where a train advances, and whether the train enters the jurisdiction of the trackside control unit can be determined according to the train position information and the jurisdiction information of the trackside control unit.

If the train enters the jurisdiction range of the trackside control unit, the vehicle-mounted control system can initiate registration operation to the trackside control unit, and after the registration is completed, the trackside control unit can send the states of trackside equipment in the jurisdiction area and all train information which is historically registered with the trackside control unit to the vehicle-mounted control system.

The vehicle-mounted control system can find the nearest train in front of the train from the history registered train information according to the train position information and find the position information of the previous train, namely the position of the nearest train in front.

In some embodiments, performing a registration operation with the trackside control unit includes: and sending the train ID to the trackside control unit for the trackside control unit to search and register the train ID in the database.

It can be understood that the database corresponding to the trackside control unit may be pre-stored with parameter information of each train, the parameter information of the train may have a corresponding relationship with a train ID, when the on-board control system of the train performs a registration operation on the trackside control unit, the train ID may be sent to the trackside control unit, and the trackside control unit may search the database for whether the related parameter information of the train exists by using the train ID, and register the train ID.

In some embodiments, the front signal location information is determined based on a train operation plan received from the train integrated monitoring center and the train location information.

It can be understood that, when the train is put into operation, the train integrated monitoring center can send the train operation plan corresponding to the train on the same day to the vehicle-mounted control system, and the vehicle-mounted control system can determine the front traffic signal position information from the train operation plan according to the train position information.

After the train operation plan is determined, the vehicle-mounted control system can determine the positions of the traffic signals corresponding to the train operation plan, and meanwhile, the position information of the traffic signal in front of the train can be found according to the train position information.

In some embodiments, the determining 120 a route section based on the train position information and the front traffic signal position information includes: and determining the route section by taking the current position of the train as a starting point and the position of the front signal machine as an end point on the basis of the position information of the train and the position information of the front signal machine.

It is understood that the route section of the train may be determined based on the train position information and the front traffic signal position information, since the current position of the train is used as the starting point and the position of the front traffic signal is used as the ending point.

In some embodiments, the train route handling method further comprises: and sending the train position information and the state information of the trackside control unit to the train comprehensive monitoring center in real time, wherein the state information of the trackside control unit is received from the trackside control unit.

It can be understood that the vehicle-mounted control system also sends train position information and trackside control unit state information to the train comprehensive monitoring center in real time, so that the train comprehensive monitoring center can monitor the position of the train and the state of the trackside control unit and further confirm the driving safety of the train in the route handling process.
