Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The Chinese Train operation Control System (CTCS) is divided into 5 levels of 0-4, and is used for monitoring the operation condition of the Train, responding to various conditions of the Train in time and adjusting the operation state of the Train.
At present, 5 levels of a CTCS correspond to different regions on an actual running track, and when a train is going to run from a current CTCS level region to a next CTCS level region, since two different level regions are monitored by different train control systems, an on-board device of the train is also converted from a CTCS system corresponding to the current CTCS level region to a CTCS system corresponding to the next CTCS level region, so that the on-board device of the train can be matched with the CTCS system in the next CTCS level region and run under the monitoring of the CTCS system.
However, most of the conventional conversion methods directly convert the current CTCS system corresponding to the CTCS hierarchical region into the next CTCS system corresponding to the CTCS hierarchical region at a fixed location, and in this case, if the next CTCS hierarchical region has a failure, the train CTCS system conversion will fail, so that the conventional conversion methods have a low success rate. Therefore, the invention provides a grade conversion method of a train operation control system, which can improve the success rate of a train when converting a CTCS system. The specific implementation steps are shown in fig. 1, and include:
101. at a specified position within the first area, the in-vehicle device is connected.
The first area is an area where a train is located when the train is on board and uses the train operation control system of the current grade.
In the present invention, a class switching call responder group, a class switching advance notice responder group, and a class switching execution responder group are preset. Wherein there are a plurality of transponders in each group of transponders.
In the invention, the current level train operation control system can be a CTCS-2 system or a CTCS-4 system, and the level train operation control system to be converted can be a CTCS-2 system or a CTCS-4 system, but it should be noted that if the current level train operation control system is the CTCS-2 system, the level train operation control system to be converted is the CTCS-4 system; and if the current grade train operation control system is a CTCS-4 system, the grade train operation control system to be converted is a CTCS-2 system.
Thus, when the train travels from the first area to the second area and crosses the class switching call responder group in the first area, the vehicle-mounted device receives a call information packet of a pre-deployed Radio Block Center (RBC), then actively calls the RBC through the wireless network, and after receiving the call information of the vehicle-mounted device, the RBC sends a session to the vehicle-mounted device, so as to connect the vehicle-mounted device, that is, the designated location is the class switching call responder group.
102. And determining the driving permission information of the train by using the vehicle-mounted equipment, and detecting the state of the target track section in the second area.
And the second area is an area corresponding to a train-mounted train operation control system of the grade to be converted.
After the step 101 is performed, the vehicle-mounted device reports the location information of the train to the RBC, and then the RBC can calculate the driving permission information of the train according to the real-time location information of the train; in addition, the RBC will also detect the status of the target track segment in the second region by interlocking.
Wherein, the target track section is the first track section in the second area.
In addition, when the RBC calculates the train driving permission information, the RBC may search forward according to the real-time position of the train to see whether an abnormal condition exists in front of the real-time position of the train until the abnormal condition is found. Therefore, the driving permission information calculated by the RBC may be position information, which is a position from the train start position reported by the vehicle-mounted device until the position before the abnormal condition is searched.
103. And judging whether the train meets the conversion condition for converting the current grade train operation control system into the grade train operation control system to be converted or not based on the running permission information and the target track section state.
In this step, it can be determined whether the train meets a conversion condition for converting the current-class train operation control system into the to-be-converted-class train operation control system according to the driving permission information and the target track section state.
Specifically, when judging whether the train meets the conversion condition for converting the current grade train operation control system into the grade train operation control system to be converted: the on-board device may be used to obtain the real-time location information of the train, and then detect whether the real-time location information of the train crosses a preset class conversion advance responder group, if so, the train may be proved to be ready to be converted from the current class train operation control system to the class train operation control system to be converted, at this time, it may be detected whether the driving permission information crosses a target execution responder in the preset class conversion execution responder group (that is, the last execution responder in the class conversion execution responder group), and whether the target track section state is idle, if the driving permission information crosses the target execution responder, and the target track section state is idle, it may be determined that the train satisfies the conversion condition, and then step 104 may be executed.
104. And sending a conversion command to the vehicle-mounted equipment.
When the train meets the conversion condition of converting the current-grade train operation control system into the grade train operation control system to be converted in step 103, the train can send a conversion command to the vehicle-mounted device, the vehicle-mounted device receives the conversion command of the RBC and confirms the conversion command, then the train operation is continuously controlled, the RBC can send driving permission information to the vehicle-mounted device after receiving the confirmation information of the vehicle-mounted device, the vehicle-mounted device generates a speed-distance mode curve under the grade train operation control system to be converted according to the driving permission information, the train operation control system to be converted is prepared, when the train operation approaches to a first execution responder in the grade conversion execution responder group, the vehicle-mounted device can prompt a Driver to convert the current-grade train operation control system into the grade train operation control system to be converted through a human-Machine Interface (DMI), the Driver performs corresponding operation according to the prompt, and then the vehicle-mounted device is converted from the current-grade train operation control system into the grade train operation control system to be converted, and then the RBC operation of the train is continuously monitored according to the sent permission.
Based on the implementation manner of fig. 1, it can be seen that the method for grade conversion of a train operation control system provided by the present invention is to connect with a vehicle-mounted device when a train is located at a designated position of a first area, where the first area is an area where the train is located when the train uses a current grade train operation control system, determine driving permission information of the train and a target track section state in a second area by using the vehicle-mounted device, where the second area is an area corresponding to the train-mounted grade train operation control system to be converted, determine whether the train meets a conversion condition for converting the train from the current grade train operation control system to the grade train operation control system to be converted according to the driving permission information and the target track section state, and send a conversion command to the vehicle-mounted device if the train meets the conversion condition, where the vehicle-mounted device converts the current grade train operation control system to be converted into the grade train operation control system according to the conversion command. According to the invention, the switching command is sent to the vehicle-mounted equipment only when the train is judged to meet the switching condition according to the driving permission information and the state of the target track section in advance, and the vehicle-mounted equipment is switched from the current-grade train operation control system to the grade train operation control system to be switched according to the switching command, so that the switching condition of the train is judged in advance compared with the prior art because the switching command is not directly switched. The invention firstly judges whether the train meets the conversion condition of converting the current grade train operation control system into the grade train operation control system to be converted, and the vehicle-mounted equipment performs conversion under the condition of meeting the condition, thereby improving the conversion success rate to a certain extent.
Further, as a refinement and an extension of the embodiment shown in fig. 1, an embodiment of the present invention further provides another class switching method for a train operation control system, as shown in fig. 2, which includes the following specific steps:
201. at a specified position within the first area, the in-vehicle device is connected.
The implementation manner of step 201 is the same as that of step 101, and the same technical effect can be achieved, so that the same technical problem is solved, and repeated details are not described herein.
202. And determining the driving permission information of the train by using the vehicle-mounted equipment, and detecting the state of the target track section in the second area.
The implementation of step 202 is the same as that of step 102, and the same technical effects can be achieved, so as to solve the same technical problems, which is not repeated herein.
203. And judging whether the train meets the conversion condition for converting the current grade train operation control system into the grade train operation control system to be converted or not based on the running permission information and the target track section state.
The implementation of step 203 is the same as that of step 103, and the same technical effects can be achieved, so as to solve the same technical problems, which is not repeated herein.
204. And sending a conversion command to the vehicle-mounted equipment.
Part of the implementation of step 204 is the same as that of step 104, and the same technical effect can be achieved, so as to solve the same technical problem, which is not repeated herein.
In addition, after the switching command is sent to the vehicle-mounted device, when the vehicle-mounted device switches from the current-class train operation control system to the class train operation control system to be switched according to the switching command, the RBC also needs to monitor whether the state of the target track section changes at any time through interlocking: for example, after a certain train in front changes lanes, the train suddenly enters a target track section in the second area, so that the state of the target track section is not idle, if the state of the track section is not idle, the train cannot enter the second area temporarily, and therefore cannot be converted into a train operation control system of a grade to be converted, and if the train operation control system of the grade to be converted is forcibly converted into the train operation control system of the grade to be converted in the first area, the grade of the train control system used by the train-mounted equipment is not matched with the area where the train-mounted equipment is located, so that the train operation efficiency is affected.
205. Whether a train specified position report sent by the vehicle-mounted equipment is received or not is detected within a specified time period.
In this step, after the switching command is sent to the vehicle-mounted device, the vehicle-mounted device switches to the train operation control system of the grade to be switched according to the switching command, and the success of the switching cannot be directly determined, and only when a train designated position report sent by the vehicle-mounted device is received, that is, a train position report sent by the vehicle-mounted device when the train is in the second area is received, the success of the switching can be determined.
Based on the above description, it is necessary to further detect whether a train designated location report sent by a vehicle-mounted device is received within a designated time period, if so, step 206 may be executed, and if not, it may be determined that the vehicle-mounted device is not switched to the to-be-switched class train operation control system, at this time, when the RBC detects a station track in the train arrival station, a manual switching command may be sent to the vehicle-mounted device, so that the vehicle-mounted device switches from the current class train operation control system to the to-be-switched class train operation control system according to the manual switching command. Therefore, the conversion can be performed manually in time under the condition that the designated position report of the train cannot be received, and the conversion success rate is improved to a certain extent.
The specified time period may be determined according to specific situations, and is not limited herein.
206. And if so, confirming that the vehicle-mounted equipment is successfully converted to the train operation control system of the grade to be converted.
If the train appointed position report sent by the vehicle-mounted equipment is received in the appointed time period, the vehicle-mounted equipment can be confirmed to be successfully converted to the grade train operation control system to be converted. At this time, it may be determined whether all cars of the train are in the second area using the on-board device.
Specifically, the vehicle-mounted device reports the real-time position information of the train to the RBC in real time, so that the RBC can determine whether the positions of all the carriages of the train uploaded by the vehicle-mounted device are in the second area, that is, whether all the trains exit the first area. If so, the connection with the vehicle-mounted equipment can be disconnected. Therefore, the resource occupation can be released, and the resource utilization rate of the system is improved.
Based on the implementation manner of fig. 2, it can be seen that the class switching method of the train operation control system according to the present invention is to preset a class switching call responder group, a class switching advance notice responder group, and a class switching execution responder group, when a train travels from a first area to a second area and crosses the class switching call responder group in the first area, the vehicle-mounted device will actively call the RBC through the wireless network, and after receiving the call information of the vehicle-mounted device, the RBC sends a session to the vehicle-mounted device, thereby connecting the vehicle-mounted device.
And then when the RBC detects that the real-time position information of the train crosses a preset grade conversion forenotice transponder group through the vehicle-mounted equipment, judging whether the train meets the conversion condition of converting the current grade train operation control system into the grade train operation control system to be converted according to the train driving permission information and the target track section state in the second area, and if so, sending a conversion command to the vehicle-mounted equipment, confirming after receiving the conversion command of the RBC by the vehicle-mounted equipment, and then continuing to control the train to operate.
Then, when the train operation approaches to the first execution responder in the grade conversion execution responder group, the vehicle-mounted equipment can be converted from the current grade train operation control system to the grade train operation control system to be converted. As is apparent from the above description, the present invention sets a plurality of transponder groups and prepares for a train switching operation when a train crosses a call transponder group, and therefore, the switching method of the present invention sets a large amount of redundant time, and the present invention determines a train switching condition first, thereby preventing a problem of a failure of switching if a failure occurs in a next CTCS class region during direct switching. In summary, the grade conversion method for the train operation control system provided by the invention improves the success rate of the vehicle-mounted equipment when converting from the current grade train operation control system to the grade train operation control system to be converted to a certain extent.
