The main technical scheme of the application is as follows: receiving low-frequency code information of a track circuit based on running of a train on the track circuit in a partial mode, and acquiring transponder message data from a transponder based on the transponder through which the train runs; judging whether the front of the train is about to enter into side line operation or not according to the low-frequency code information; if yes, deleting the stored transponder message data.
Description
Technical Field
The present disclosure relates to the field of rail transit technologies, and in particular, to a method and an apparatus for deleting transponder message data in a vehicle-mounted part mode.
Background
In a full mode (Full Supervision mode, FS mode) of the CTCS-2 level train control system, the vehicle calculates a continuous speed profile of the target speed distance using the received track circuit data and transponder message data to monitor the train running on the track line based on the continuous speed profile.
Based on the acquired transponder message data, the vehicle is operated in a partial mode (Part Supervision mode, PS mode) before the vehicle has not yet confirmed that the vehicle can be switched to the full mode, as illustrated in fig. 1, which shows a schematic view of an operation scenario of the vehicle in the partial mode, in fig. 1: transponders (BG 1, BG2, and BG 3); two track sections 103BG and 103AG near the X-semaphore; positive line X-SN and lateral line X-SBN; and low frequency code information (LU, U2S, UUS, L5) of the track circuit.
As in the operation scenario illustrated in fig. 1, the vehicle operates in the partial mode, and the transponder BG1 defines a line data C1 packet in the downstream direction (i.e. downstream direction when operating to the right as shown in fig. 1), but no message data in the complete mode is transferred, and the C1 packet defines line data in the positive line. However, when the vehicle runs past the transponder BG2, the vehicle cannot receive corresponding transponder message data due to ground faults, and when the vehicle runs past the transponder BG3, the vehicle cannot receive corresponding transponder message data due to ground faults.
Assuming that the pre-arranged route of the vehicle is a side route and the line data of the side route are stored in the transponder BG3, however, since the vehicle fails to receive the transponder message data provided by the transponder BG3, as shown in fig. 1, after passing over the X-ray signal, the vehicle will continue to use the C1 packet described in the transponder BG1, which means that the vehicle uses the wrong line data, which will bring about a driving risk.
At present, the countermeasure adopted is to utilize the frequency locking in the line data C1 packet to compare with the carrier frequency received from the track circuit, if the frequency locking is inconsistent, the vehicle-mounted can actively output braking to protect, so as to prevent the safety risk caused by the fact that the vehicle-mounted still adopts the wrong line data C1 packet to continue to operate.
However, on the premise that the vehicle does not receive the transponder message data sent by the transponder BG3, since the information of frequency locking and the information carried by the carrier frequency are only uplink or downlink of the train, if the situation that the frequency locking in the line data C1 packet is consistent with the carrier frequency received from the track circuit happens, the vehicle will not brake at this time, but will still continue to control the train operation with the wrong line data C1 packet, which is inconsistent with the actual running line (i.e. the requirement is a side line), and the running risk cannot be avoided.

Detailed Description
Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application 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.
Now in the train operation scenario in the partial mode, as shown in fig. 1, the transponder BG1 defines a line data C1 packet in the downstream direction (i.e. downstream direction when running to the right as shown in fig. 1), the C1 packet defines line data of a positive line, but the on-board pre-arranged route is a side route, and the line data of the side route is stored in the transponder BG 3.
In such an operation scenario, the inventor finds that if the train part mode passes through the transponders BG2 and BG3, and the vehicle cannot receive the corresponding transponder message data due to ground faults and the like, then as shown in fig. 1, after the vehicle passes over the X-ray signal, the vehicle will continue to use the line data C1 packet described in the transponder BG1, which means that the vehicle uses the line data incorrectly, and running risks will be brought.
The inventor found that, from the perspective of avoiding the safety risk, whether the transponder message data provided by the transponder BG2 or BG3 is normally received or not, if the vehicle uses the latest received transponder message data after the transponder BG3 is operated in the partial mode, the situation that the line data C1 packet described in the transponder BG1 is continuously used will not occur, so that the use of the wrong transponder message data to the subsequent train operation line is effectively avoided.
It should be noted that, because the transponders are arranged in sequence in advance on the track line, the message data provided by different transponders are continuously received based on the running of the train passing the transponders, and the new transponder message data can cover the historical transponder message data to be applied to the subsequent running line, even if the current historical transponder message data is deleted by the vehicle, the normal running of the train in the partial mode is not influenced temporarily, and the new transponder message data can be received again along with the running of the train to be applied to the subsequent running line.
Based on the above conception, the implementation of the present application provides a method for deleting transponder message data in a vehicle-mounted part mode, as shown in fig. 2, and the following specific steps are provided for this embodiment of the present application:
101. and in the partial mode, based on the running of the train on the track line, receiving the low-frequency code information of the track circuit, and based on the passing transponder of the train, acquiring transponder message data from the transponder, wherein the transponder message data comprises a data packet defining the positive line data.
The partial mode (Part Supervision mode, PS mode) refers to a vehicle control mode of the CTCS-2 train, and the fixed speed limit is only 45km/h in the partial mode.
The track circuit code is vehicle-mounted driving permission information obtained from the ground track side equipment in real time.
In the embodiment of the application, in the partial mode, for a running train, the vehicle can receive data information of two aspects: on the one hand, low-frequency code information of the track circuit is received; on the other hand, the transponder message data corresponding to each transponder is acquired based on the transponder group running through, and since the transponder message data includes a data packet defining the positive line data, such as a C1 packet, the train running is controlled according to the positive line data.
The track circuit low frequency code information will be mainly explained below.
For example, the low frequency code information of the track circuit that may be received on-board from the ground trackside equipment may include, but is not limited to: l5 code, L4 code, L3 code, L2 code, L code, LU code, U code, HU code, H code, U2 code, UU code, U2S code, UUS code, JC code, conversion code and no code.
The explanation of the low frequency code information of the track circuit is as follows, for example, in the following table in "the corresponding relation between track circuit information and vehicle-mounted monitoring speed in the partial mode of the record" in the technical condition of CTCS-2-level train control vehicle-mounted equipment "in the national railway industry standard of the people's republic of China (TB/T3529-2018).
List one
The meanings of the low frequency code information of the track circuit shown in table one are described in "definition and distribution of cab signal information" in the national railway industry standard for the people's republic (TB/T3060-2016), and the information meanings indicated by the different codes are shown in table two, for example, in "CTCS-2/3 stage section".
Watch II
According to the information meanings corresponding to the different codes, in the embodiment of the application, if the vehicle receives other track circuit codes except HU codes, JC codes, conversion codes and no codes, namely when the condition is met, the vehicle can keep the partial mode to operate all the time.
102. And judging whether the front of the train is about to enter into side line operation or not according to the low-frequency code information.
In the embodiment of the present application, since it is determined based on step 101 that the received transponder message data includes a data packet defining the positive line data, it means that the train operation is controlled according to the positive line data.
However, if it is determined that the front of the train is about to enter into the side track operation based on the received track circuit low frequency code information during the running of the train, this means that the running direction of the train is about to be changed, and if the running of the train is controlled by continuing to use the previously received positive track line data, a situation in which the erroneous transponder data is applied to the subsequent train running line may occur, which may bring about a running hazard.
103a, if it is determined that the front of the train is about to enter into side line operation, deleting the currently stored transponder message data.
103b, if it is determined that the front of the train does not enter into the side line operation, in the process of continuing the operation of the train, after the vehicle-mounted vehicle receives new transponder message data from the next transponder, the new transponder message data is utilized to be applied to a subsequent operation line.
In the embodiment of the present application, the purpose of determining whether the front of the train is about to enter into the side line operation based on the low frequency code information is to determine whether the front of the train is about to enter into the side line operation, if the front of the train is encountered, the line data used is necessarily different for different lines about to run, so the scheme adopted in the embodiment of the present application is that the vehicle deletes the historical transponder message data immediately before entering into the side line position, so as to avoid adopting the wrong historical transponder message data when running into the side line.
For example, as shown in fig. 1, due to ground faults and other factors, the train runs through the transponder BG3 but fails to receive corresponding transponder message data, and the historical transponder message data is deleted immediately before entering the side line position, so that the line data C1 packet obtained based on the transponder BG1 is deleted, and the situation that wrong line data is used in the subsequent running route is avoided.
As described above, the embodiment of the present application does not rely on the type of traffic signal defined in the line data C1 packet in the transponder message data to determine the type of X traffic signal as shown in fig. 1, and normally, if the X traffic signal can be determined to be an incoming traffic signal or an outgoing traffic signal based on the line data C1 packet, it can be predicted that there is a side-line traffic channel in front based on the traffic signal type. When the vehicle enters the track circuit section where the X signal machine is located, the vehicle is controlled to delete the current stored historical transponder message data.
However, it is not necessary to delete the entire historical transponder message data, and it is preferable to delete the following packets, such as packets E5, E21, E27, C1, C2, C3, C4, and E68, in the historical transponder message data, which affect the running performance of the train on the line. For example, E72 is to store station name information, and whether to delete or not will not adversely affect the subsequent operation, and deletion may not be necessary.
The information meaning of each data packet is as follows:
e5: a transponder link for linking a transponder group that is expected to pass in front of the link, defining a response (emergency braking, maximum service braking, no response) after the vehicle-mounted transponder loses the linked transponder;
e21: line gradient, defining gradient information of a track line, ascending slope, or descending slope;
e27: the track speed, defining the allowable running speed of the track, such as starting from the D_static distance, and defining the maximum allowable speed V_static of the track;
c1: the method comprises the steps of a track section information packet, a carrier frequency sent by a front track section to a vehicle is defined, the section length of each section is defined, and the type of a signal machine at the starting point of the front section is defined;
c2: temporary speed limit information package, defining the length of the effective section of the front temporary speed limit information, and defining the length of the temporary speed limit section
And C3: the interval reverse running information packet is used for defining the length of interval reverse running through a C3 packet aiming at a line occupying an inspection code by a track circuit during interval reverse running;
and C4: a large number turnout information packet defines the maximum allowable speed of the lateral passing of the train;
e68: the special section defines a bridge in front, the tunnel is used for prompting a driver to pay attention to the lookout, a split-phase area in front is defined, and the vehicle-mounted information is used for outputting split-phase control.
However, the above scheme too relies on the line data C1 packet in the historical transponder message data, and it is assumed that the message data received by the transponder BG1 does not have such a C1 packet, or the traffic signal type passing through is not predefined in the C1 packet, so that it is not known whether there is a side line possible in front of the train running, which makes it difficult to accurately determine whether to perform the operation of deleting the currently stored historical transponder message data. However, the embodiment of the application does not depend on the C1 packet in the transponder message data, but judges based on the track circuit code, so that the time for deleting the transponder message data can be more accurately met, the current running condition of the train is not affected, and the situation that wrong line data are used on a front line is avoided.
In the above, the embodiment of the application provides a method for deleting transponder message data in a vehicle-mounted part mode, in which the vehicle-mounted part mode is based on a transponder through which a train runs, the transponder message data is continuously received from the transponder, and the vehicle-mounted part is based on the train running on a track line, and can also receive low-frequency code information of the track circuit, so that according to the two aspects of data information received by the vehicle-mounted part, if the vehicle-mounted part judges that the front of the train is about to enter into a side line running according to the low-frequency code information, the stored transponder message data is judged to be deleted, and therefore, even if the message data provided by a certain transponder is missed due to ground faults and the like before entering into the side line position, the situation that the wrong transponder data is applied to a subsequent train running line can not occur.
Compared with the prior art, the technical problem that the existing scheme is insufficient for accurately judging whether the vehicle uses the wrong line data to run is solved, and the method for deleting the stored historical transponder message data is provided.
Further, for more detailed explanation, the embodiment of the present application further provides another method for deleting transponder message data in the vehicle-mounted part mode, as shown in fig. 3, and the following specific steps are provided for this embodiment of the present application:
201. and in the partial mode, based on the running of the train on the track line, receiving the low-frequency code information of the track circuit, and based on the passing transponder of the train, acquiring transponder message data from the transponder, wherein the transponder message data comprises a data packet defining the positive line data.
In the embodiment of the present application, the explanation of this step is referred to step 101, and is not repeated here.
202. And judging whether the vehicle-mounted meets the condition of going out of the partial mode.
203a, if it is determined that the vehicle meets the condition of going out of the partial mode bar, the operation of deleting the currently stored transponder message data is not required to be executed.
The scheme for deleting the stored historical transponder message data provided by the embodiment of the application is only suitable for the partial mode.
For example, for the full mode, its security mechanism is again different. For example, in the special handling of the full mode at the side track approach, if a transponder is lost, received in an abnormal condition, etc., during the passage of the train side track approach past the outboard track circuit section of the approach signal, the saved line data should be discarded to the partial mode and the maximum service brake triggered.
The embodiment of the present application makes a pre-determination using step 202 and continues to perform subsequent steps if still in the partial mode.
Illustratively, for the pre-determined requirements of step 202, the refinement implementation method is as follows:
judging scheme 1, wherein a C5 absolute parking packet in received transponder message data consistent with the direction brakes and parks, and after emergency braking is relieved manually, the vehicle-mounted exit part mode enters a standby mode;
judging scheme 2, receiving effective C1, E21 and E27, enabling the vehicle to have full mode driving capability and correctly receive the track circuit code, and enabling the vehicle to exit from the partial mode and enter into the full mode.
Wherein, C1, E21, E27 and C5 are all data packets in the transponder message data, and the information meaning of each data packet is as follows:
c1: the method comprises the steps of a track section information packet, a carrier frequency sent by a front track section to a vehicle is defined, the section length of each section is defined, and the type of a signal machine at the starting point of the front section is defined;
e21: line gradient, defining gradient information of a track line, ascending slope, or descending slope;
e27: the track speed, defining the allowable running speed of the track, such as starting from the D_static distance, and defining the maximum allowable speed V_static of the track;
c5: and the absolute parking information packet receives the information packet and outputs emergency braking on the vehicle to prohibit the train from passing.
Further, the embodiment of the present application provides a specific implementation method for performing validity judgment on each of the data packets C1, E21, E27, including the following steps:
1. vehicle-mounted judging whether the C1 packet is valid or not: judging that the acquired NID_BG information is valid and cannot be empty from the transponder message data; the decision on N_ITER in the C1 packet must be greater than 0. When the above two conditions are satisfied, the vehicle-mounted determines that the C1 pack is valid.
It should be noted that, after receiving the transponder message data, the vehicle-mounted device analyzes the transponder group and stores the analyzed different data packets into an overall structure variable; among these are global construct variables for the C1 packet, global construct variables for the E21 packet, global construct variables for the E27 packet, and global construct variables for the E5 packet.
In the packet header information frame of the transponder packet data, the number of bits of the variable nid_c is "10" and means "region number (high 7 bits=large region number, low 3 bits=partition number)", the number of bits of the variable nid_bg "is" 14 "and means" transponder identification number (high 6 bits=station number, low 8 bits=transponder number) ", and nid_bg is judged to be valid by judging that two fields nid_c and nid_bg in the packet header of the resolved transponder group are not 0 at the same time.
And in the transponder linked packet structure, the number of bits of the variable "n_iter" is "5" and means "the number of groups of linked transponders included".
2. The vehicle determines whether the E21 packet is valid: judging that the acquired NID_BG information is valid and cannot be empty from the transponder message data; the decision on N_ITER in E21 packet must be greater than 0. When the above two conditions are satisfied, the vehicle-mounted determines that the E21 packet is valid.
3. The vehicle determines whether the E27 packet is valid: judging that the acquired NID_BG information is valid and cannot be empty from the transponder message data; the decision on N_ITER in the E27 packet must be greater than 0. When the above two conditions are satisfied, the vehicle-mounted determines that the E27 pack is valid.
203b, if the vehicle-mounted is determined not to meet the condition of the partial mode, judging whether the front of the train is about to enter into side line operation according to the low-frequency code information.
In the embodiment of the application, the steps are specifically detailed as follows:
if the track circuit code received in the previous cycle is not Huang Huangshan and the track circuit code received in the current cycle is Huang Huangshan, it is determined that the side track operation is about to be entered in front of the train.
If the track circuit code received in the previous cycle is not yellow and the track circuit code received in the current cycle is Huang Huang, determining that the side line operation is about to be entered in front of the train.
Thus, for the track circuit code received in two adjacent periods, if the track circuit code is changed from a non-UU code or UUs code to a UU code or UUs code, it is determined that the front of the train is about to enter into side track operation.
204bc, if it is determined that the front of the train is about to enter into side running, judging whether the vehicle is about to enter into a full mode but does not have full mode driving capability.
204bd, if it is determined that the front of the train does not enter into the side line operation, in the process of continuing the operation of the train, after the vehicle-mounted vehicle receives new transponder message data from the next transponder, applying the new transponder message data to a subsequent operation line.
205, bce, if it is determined that the vehicle is about to be shifted to the full mode but has not yet had full mode driving capability, not executing the operation of deleting the currently stored transponder message data.
In the partial mode, there is a special case, as explained in connection with fig. 1, that for transponder message data received from transponder BG1, if the received data packets C1, E21, E27 and E5 are valid, but the vehicle has no full mode driving capability yet, for example, although C1 or E27 is valid, the vehicle still enters the data validation range defined by C1 or E27 respectively, for example, in fig. 1, if the definition is validated by an X-ray signal, the vehicle needs to be validated to go into full mode, and at this time the currently stored transponder message data should not be deleted, otherwise the vehicle cannot normally go into full mode.
Wherein E5 is a transponder link, which is used to link a transponder group that is expected to pass in front of the link, and defines the response (emergency braking, maximum service braking, no response) of the vehicle-mounted transponder after losing the linked transponder.
And, the vehicle-mounted determines whether the E5 packet is valid as follows: judging that the obtained E5 packet link information is effective from the transponder message information; the decision on N_ITER in E5 packet must be greater than 0. When the above two conditions are satisfied, the vehicle-mounted determines that the E5 packet is valid.
It should be noted that, this step 205bce is a special case, and is not negligible, otherwise it will affect the normal transition of the train into the full mode.
205bcf, if the situation that the vehicle is about to be shifted into the full mode does not exist, deleting the currently stored transponder message data.
Further, in the partial mode, if it is determined that the vehicle is not about to be shifted to the full mode, it should be considered that the error line data is applied to the subsequent operation line without receiving the message data provided by a certain transponder running therethrough, and thus the currently stored historical transponder message data should be deleted immediately before entering the side line position.
