It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
First, relevant equipment related to train operation control is explained:
vehicle-mounted controller, english name: the vehicle on-board controller is abbreviated as VOBC in English, is used for realizing the functions of Automatic Train Protection (ATP) and Automatic Train Operation (ATO), and is used for reporting the Train position in real time and acquiring the moving block of Train moving authorization to replace the fixed track section block to realize the Train Operation control.
Zone controller, english name: zone Controller, ZC, acronym, zone Controller, which is an important component of CBTC trackside safety processing, divides a train line into a plurality of control zones, each control Zone is responsible for one Zone Controller, and the Zone Controller in the responsible Zone is responsible for providing a Movement Authority (MA) to the train to inform the train of the farthest distance allowed to advance.
And the vehicle-mounted controller sends the position information of the starting end of the train to the regional controller, and the regional controller generates train movement authorization according to the position information of the starting end of the train and the trackside resource information.
Fig. 1 is an exemplary flowchart of a method for switching a train running direction according to an embodiment of the present application, where the method is performed by an on-board controller, as shown in fig. 1, and the method for switching the train running direction includes:
in step 101, a train is stopped on a retracing track, and state change information of a first end of the train is obtained, wherein the first end is a starting end of the train in a running direction before the train is stopped stably.
Specifically, after the train stops stably on the retraced track, the train body of the train remains stationary, and at this time, if the physical key for starting train operation is removed from the driver control room by the train driver, the train stops operating, where the physical key for starting train operation is used for starting the train, when the physical key for starting train operation is inserted and the train is started, various devices on the train are ready for operation, some devices may need to be charged and initialized, some devices may need to complete preparation for normal operation, some devices may need to establish communication with each other, and the like. In the embodiment of this application, before the train stops steadily at the track of turning back, regard the initiating terminal of train traffic direction as first end, can know that, after the train finishes the traffic direction conversion, the initiating terminal of train traffic direction has exchanged with rear of a vehicle one end this moment.
Specifically, in an embodiment of the present application, the stopping of the train on the retraced track and the obtaining of the state change information of the first end of the train include:
and acquiring that the physical key of the first end is switched from an inserting state to an extracting state.
Specifically, when the physical key of the first end is pulled out, the state change of the first end is triggered, and the changes not only relate to the information change of the vehicle, but also relate to the change of relevant parameters during the running of the vehicle, such as the movement authorization of the vehicle and the like. When the physical key at the first end is pulled out, the vehicle-mounted controller triggers and executes a corresponding program for controlling the first end.
And switching the physical key of the first end from the inserting state to the extracting state as the state change information of the first end.
Specifically, the physical key at the first end is switched from the inserted state to the extracted state as the first end state change information, that is, when the physical key at the first end is extracted from the driver control room, the vehicle-mounted controller records the state change information, so as to control the change of the vehicle-mounted controller.
In step 102, state change information of a second end of the train is obtained according to state change information of the first end of the train, wherein the second end is the end, opposite to the first end, of the train.
Specifically, in the present application, two ends of the train in the moving direction are respectively set as a first end and a second end, before the train is stopped on the retraced track, the starting end of the train in the moving direction is the first end, and the tail end of the train in the moving direction is the second end.
Specifically, in an embodiment of the present application, the obtaining the second end state change information of the train according to the first end state change information of the train includes:
and controlling the first terminal to be switched from an activated state to a standby state according to the state change information of the first terminal.
Specifically, when the physical key at the first end is pulled out from the cab, the train disconnects the corresponding communication connection and electrical connection, and stops the operation of the corresponding equipment, and at the moment, the on-board controller also controls the on-board controller to switch the on-board controller from the activated state to the standby state, so that the physical key is pulled out, which indicates that the train does not operate any more at the moment, and the train does not need the on-board controller to control the train to operate temporarily.
And when the first end is in a standby state, the physical key for acquiring the second end is switched from an extraction state to an insertion state.
Specifically, the physical key is allowed to be inserted into the cab of the second end only when the first end is in the standby state, because if the first end is not in the standby state, when the physical key is inserted into the second end, the on-board controller starts protection without accepting state change of the second end, when the first end of the train is in the standby state, and after the physical key is inserted into the second end of the train, the train starts preparation of corresponding electrical equipment, for example, some equipment may be powered on, some equipment may be initialized, some equipment may establish mutual connection, some equipment may complete handshake with external equipment, and the like, and after the physical key of the second end is inserted, the train completes preparation of electrical and communication of all physical equipment.
And switching the physical key of the second end from the pulled-out state to the inserted state as the second end state change information.
Specifically, after the physical key is inserted into the cab of the second end of the train, the second end of the train will have some state changes, and then the state changes of the train caused by switching the physical key of the second end from the pulled-out state to the inserted state are used as the second end state change information.
In step 103, the train operation direction is controlled to be switched according to the first end state change information and the second end state change information.
Specifically, when the physical key is pulled out from the first end, each device on the train is changed from a working state to a non-working state, at the moment, the vehicle-mounted controller is also switched from an activated state to a standby state, namely, the train stops, the vehicle-mounted controller temporarily stops controlling the train to run, when the physical key is inserted from the second end, the train completes corresponding electrical or communication preparation, at the moment, the vehicle-mounted controller is also switched from the standby state to the activated state, the vehicle-mounted controller starts to control the running direction of the train, at the moment, because the physical key is pulled out from the first end and is inserted into the second end, the original first end of the train is switched into a starting end, the second end of the train is switched into a tail end, the first end is the starting end, the train position information required to be obtained by the area controller is not the position information of the first end any more, but the position information of the second end is the position information of the second end, because the devices on the train have already completed corresponding electrical and communication preparation according to the condition that the second end of the train is started, the second end of the train to run, and then the vehicle-mounted controller completes the preparation for the running of the tail end.
It should be emphasized that the train operation direction conversion in the manual driving mode is to interchange the start end and the tail end of the train, that is, to interchange the ascending and descending of the train, for example, when the train is in the ascending state, the first end of the train is the start end, the second end is the tail end, then when the train is in the descending state, the second end of the train is the start end, the first end is the tail end, and the first end is the start end, the movement authorization is generated according to the position information of the first end, the train operation direction control is performed, when the second end is the start end, the movement authorization is generated according to the position information of the second end, the train operation direction control is performed, and the process of performing the manual operation direction conversion is the process of changing the vehicle operation direction and regenerating the movement authorization according to the operation direction.
Specifically, in an embodiment of the present application, the controlling the train operation direction conversion according to the first end state change information and the second end state change information includes:
and determining the change direction of the insertion position of the physical key according to the first end state change information and the second end state change information.
Specifically, after the physical key is pulled out from the first end, the first end is no longer the starting end of the train running direction, and after the physical key is pulled out from the first end and the physical key is inserted into the second end, the changing direction of the physical key inserting position is determined through the change of the physical key inserting position.
And determining the running direction in the activated state according to the first end state change information and the second end state change information.
Specifically, the physical key is pulled out by the first end of the train, so that the on-board controller is changed from the active state to the standby state, at the moment, the train stops running, the first end of the train temporarily stops serving as the starting end of the train running, at the moment, the physical key is inserted into the second end of the train, so that the on-board controller is changed from the standby state to the active state, the on-board controller acquires train running information sent by various devices on the train according to the fact that the physical key is inserted into the second end, and the on-board controller takes the second end of the train as the starting end of the train running, so that the running direction of the second end of the train in the active state is determined.
And when the change direction is consistent with the running direction in the activated state, acquiring the physical position of the starting end of the running direction in the activated state as positioning information.
Specifically, if the train moving direction is not changed, that is, the physical key is continuously inserted into the first end of the train, the physical position of the starting end is not sent again, and if the changing direction of the train moving direction is the same as the moving direction of the activated state, that is, the train moving direction is switched in the embodiment of the present application, the second end of the train is used as the starting end of the train moving direction, and is consistent with the starting end of the train moving direction obtained by the onboard controller in the activated state, so that the onboard controller uses the physical position of the starting end of the moving direction in the activated state as the positioning information.
And sending the positioning information to a regional controller.
Specifically, after the on-board controller acquires the positioning information of the start end of the running direction in the activated state, the positioning information is sent to the area controller, the area controller generates the movement authorization according to the positioning information and the trackside resource information, and the movement authorization is sent to the on-board controller, so that the on-board controller controls the train to run according to the movement authorization.
Specifically, in an embodiment of the present application, before sending the positioning information to the area controller, the method further includes:
and when the vehicle-mounted controller is determined not to finish the registration to the regional controller, sending a registration request to the regional controller.
Specifically, before the vehicle-mounted controller sends the positioning information to the zone controller, it needs to first determine whether communication is established with the zone controller, if communication is not established, registration of the vehicle-mounted controller to the zone controller needs to be completed, and since the zone controller is arranged on a train running track and keeps working in full time, after the vehicle-mounted controller is switched from a standby state to an active state, a registration request needs to be sent to the zone controller by the vehicle-mounted controller, and after the registration request sent by the vehicle-mounted controller is passed by the zone controller, registration of the vehicle-mounted controller to the zone controller is completed.
And when the vehicle-mounted controller is determined to be registered with the regional controller, sending a positioning position report to the regional controller, wherein the positioning position report comprises the physical position of the starting end of the running direction in the activated state.
Specifically, after the on-board controller completes registration with the zone controller, the zone controller sends a location report acquired by the zone controller, where the location report includes, but is not limited to, a physical location of a starting end of the running direction in the activated state.
According to the method and the device, the vehicle-mounted controller acquires the state change information of a first end of a train when the train is stopped stably on a turn-back track, and acquires the state change information of a second end of the train according to the state change information of the first end of the train; and the vehicle-mounted controller controls the running direction of the train to be switched according to the state change information of the first end and the state change information of the second end. According to the method and the device, the condition change information of the first end and the second end of the train is directly obtained without pressing a turn-back button, the vehicle-mounted controller is triggered to trigger data exchange, and the train running direction conversion under the manual driving mode is realized.
Fig. 2 is an exemplary flowchart of a method for switching a train running direction according to another embodiment of the present application, and as shown in fig. 2, the method for switching the train running direction of the present application is performed by a first onboard controller and a second onboard controller, and includes:
in step 201, a train is stopped on a retraced track, and the first onboard controller obtains state change information of a first end of the train, where the first end is a starting end of a running direction of the train before the train is stopped.
Specifically, when the train is not stopped on the retraced track, the first onboard controller controls the first end to control the train to run as the starting end of the train running, so that the first onboard controller obtains the position information of the first end in real time and obtains the movement authorization generated by the area controller according to the position information of the first end in real time; when the train stops stably on the retraced track, the train body of the train keeps still, if the physical key for train control is pulled out from a cab of a driver at the first end at the moment, the train stops running, the physical key for train control is used for starting train running, when the physical key for train control is inserted and the train is started, various devices on the train also enter a working state from a standby state, some devices may need to be charged and initialized, some devices may need to complete preparation work for normal running, some devices may need to establish communication among each other, and the like. In the embodiment of the application, before the train stops stably on the retracing track, the starting end of the running direction of the train is used as the first end, and it can be known that after the train finishes the running direction conversion, the starting end and the tail end of the train are interchanged.
Specifically, in an embodiment of the present application, the stopping of the train on the retraced-back track, the acquiring, by the first onboard controller, the state change information of the first end of the train includes:
the first vehicle-mounted controller obtains that a physical key of the first end is switched from a plug-in state to a pull-out state.
Specifically, when the physical key of the first end is pulled out, the state change of the first end is triggered, and the changes not only relate to the information change of the vehicle, but also relate to the change of relevant parameters during the running of the vehicle, such as the movement authorization of the vehicle and the like. When the physical key at the first end is pulled out, the first vehicle-mounted controller triggers and executes a corresponding program for controlling the first end.
The first onboard controller switches the physical key of the first terminal from an inserted state to an extracted state as the first terminal state change information.
Specifically, the first onboard controller switches the physical key at the first end from the inserted state to the extracted state as the first end state change information, that is, when the physical key at the first end is extracted from the driver control room, the running state of the train and the related data of various devices on the train, which take the first end as the starting end of train running, will both change, and the first onboard controller will record these change information as the first end state change information.
In step 202, the first onboard controller sends the first terminal state change information to the second onboard controller.
Specifically, due to the periodic interaction of the information between the first onboard controller and the second onboard controller, when the state of the first end acquired by the first onboard controller changes, the second onboard controller will also acquire the state change information of the first end in time.
In step 203, the second onboard controller obtains state change information of a second end of the train according to state change information of the first end of the train, where the second end is an end of the train opposite to the first end.
Specifically, because the first onboard controller and the second onboard controller periodically exchange information, when the state of the first end acquired by the first onboard controller changes, the second onboard controller will also acquire the state change information of the first end in time, and it should be particularly noted that, in the embodiment of the present application, only when the state of the first end changes, the state of the second end can be allowed to change, because in train operation, only one end can be used as a starting end of train operation for ensuring operation safety, the train operation must be controlled by collecting fixed equipment operation parameters of the starting end, if at this time, the equipment operation parameters of the second end as the starting end of train operation are also collected, a disturbance of train operation control will occur, which affects train operation safety, and because the second onboard controller is in a hot standby state, the second onboard controller also collects position information of the second end in real time, and acquires the state change information of the second end of the train.
Specifically, in an embodiment of the present application, the obtaining, by the second onboard controller, the second end state change information of the train according to the first end state change information of the train includes:
and the second vehicle-mounted controller determines that the first vehicle-mounted controller is switched from an activation state to a hot standby state according to the first terminal state change information.
Specifically, when the physical key of the first end is pulled out from the driver control room, the data and the related control command acquired by the device on the train by taking the first end as the starting end of the train operation are also stopped, because the train is about to stop operating, at this time, the first onboard controller is also switched from the activated state to the hot standby state according to the state change information of the first end. The first vehicle-mounted controller does not exit from the work after being switched to the hot standby state, the hot standby state is ready to be replaced at any time to become the activated state, the first vehicle-mounted controller normally receives relevant data of the first end, such as position information of the first end of the train, but does not control the running of the train, and the first vehicle-mounted controller entering the hot standby state cannot obtain the movement authorization any more, and cannot control the running of the train without the movement authorization.
And when the first onboard controller is in the hot standby state, the second onboard controller acquires that the physical key at the second end is switched from the pull-out state to the plug-in state.
It is particularly emphasized that the physical key can only be inserted at the second end of the train if the first onboard controller switches from the active state to the hot standby state. When the physical key is inserted into the cab at the second end, the train starts the work preparation of the corresponding electrical equipment, for example, some equipment may be powered on, some equipment may be initialized, some equipment may establish mutual contact, some equipment may complete the handshake with the external equipment, and the like, and when the physical key at the second end is inserted, the train completes the electrical and communication preparation of all the physical equipment.
The second onboard controller switches the physical key of the second terminal from the pulled-out state to the plugged-in state as the second terminal state change information.
Specifically, the second onboard controller switches the physical key of the second end from the pulled-out state to the plugged-in state as the second end state change information, that is, when the physical key of the second end is pulled out from the driver control room, the running state of the train and relevant data of various devices on the train, which are in charge of monitoring the running parameters of the second end, after the physical key of the second end is plugged in, will all change, and the second onboard controller will record the change information as the second end state change information.
In step 204, the second onboard controller controls the train operation direction conversion according to the second end state change information.
Specifically, the first onboard controller is changed from the activated state to the hot standby state due to the state change of the first end, the second onboard controller is changed from the hot standby state to the activated state due to the state change of the second end, the first onboard controller and the second onboard controller complete position exchange at the moment due to the fact that the second onboard controller in the activated state controls the train to run, and the change of the traveling direction of the train can be controlled through the state change of the first onboard controller and the second onboard controller.
Specifically, in an embodiment of the present application, the controlling the train running direction conversion by the first onboard controller and the second onboard controller according to the first end state change information acquired by the first onboard controller and the second end state change information acquired by the second onboard controller, includes:
the second onboard controller receives the physical position of the first end from the first onboard controller, and the physical position of the first end is initial positioning information.
Specifically, in the running process of the train, the first onboard controller acquires the position information of the first end and the position information of the second end in real time, so that after the physical key is inserted into the second end, the first onboard controller needs to send the acquired position information of the first end and the acquired position information of the second end to the second onboard controller, and information interaction between the second onboard controller and the first onboard controller is completed.
And the second vehicle-mounted controller determines that the second vehicle-mounted controller is switched from the hot standby state to the activation state according to the second terminal state change information.
Specifically, after the physical key is inserted into the second terminal, the second onboard controller can determine that the second onboard controller is converted from the hot standby state into the active state according to the state change information of the second terminal.
The second onboard controller obtains a physical location of the second end when the second onboard controller is in an active state.
Specifically, after the second onboard controller is switched from the hot standby state to the active state, the second onboard controller acquires the physical location of the second end.
And the second vehicle-mounted controller replaces the initial positioning information by using the physical position of the second end to obtain the current positioning information.
And the second vehicle-mounted controller sends the current positioning information to the area controller.
Specifically, after the second onboard controller finishes registering with the area controller, the second onboard controller sends the position information of the second end to the area controller, and the area controller generates the mobile authorization according to the position information of the second end and the trackside resource information and sends the mobile authorization to the second onboard controller.
Specifically, in an embodiment of the present application, before the second on-board controller sends the current positioning information to the area controller, the method further includes:
when the second vehicle-mounted controller determines that the registration with the area controller is not finished, the second vehicle-mounted controller sends a registration request to the area controller;
specifically, only one starting end in the running direction is needed when the train runs, that is, one vehicle-mounted controller is used as the vehicle-mounted controller for the master control of the running of the train, after the second vehicle-mounted controller becomes the master control system, the first vehicle-mounted controller will not control the running of the train any more, and at this time, the first vehicle-mounted controller and the regional controller must be logged out, so that the movement authorization sent by the regional controller is not received by the first vehicle-mounted controller, and the normal running of the train is not influenced.
When the second onboard controller determines that registration with the zone controller has been completed, the second onboard controller sends a location report to the zone controller, the location report including the current location information.
Specifically, after the second onboard controller completes registration with the zone controller, the zone controller sends a location report acquired by the zone controller, where the location report includes, but is not limited to, a physical location of a starting end of the recorded running direction.
According to the method, a first vehicle-mounted controller acquires state change information of a first end of a train when the train is stably stopped on a retraced track, and a second vehicle-mounted controller acquires state change information of a second end of the train according to the state change information of the first end of the train acquired by the first train controller; and the second vehicle-mounted controller controls the running direction of the train to be switched according to the state change information of the second end. According to the method and the device, the turn-back button does not need to be pressed, the state change information of the first end and the second end of the train is directly obtained, the first vehicle-mounted controller and the second vehicle-mounted controller are triggered to trigger data exchange, and the train running direction conversion under the manual driving mode is realized.
It should be particularly noted that, in some embodiments, the area controllers may not be the same area controller, and when the train is turned back and is stopped stably on a track, an area where the train is located may span two area controllers, such as a first area controller and a second area controller, at this time, when the first area controller receives the first end position information sent by the first onboard controller, the first area controller generates a movement authorization of the start end when the first end is the train running direction; and when the second area controller receives the second end position information sent by the second vehicle-mounted controller, generating the movement authorization of the starting end when the second end is the train running direction.
