Description
Technical Field

Background
Along with the development and research of railway train control technology, a large number of field verification tests need to be carried out, if tests are carried out on existing high-speed railway lines, particularly tests needing special transponder messages, in order to guarantee normal operation, the test can only be carried out by replacing a transponder at a skylight point, the test needs to be stopped before the skylight point is finished, the transponder messages are restored, and otherwise normal operation is influenced. The need to replace the transponder for each test is labor intensive, and testing only at skylight points increases the test cycle.
Meanwhile, in the process of modifying the existing line, if the transponder group needs to be added or modified, it is necessary to ensure that all the transponder groups are installed, if the transponder group is not installed or cannot work normally, that is, only one or active transponder LEU is installed on one transponder group or the active transponder LEU cannot work normally, when a train passes through the transponder group which is not installed, a fault reaction is performed, so that the train cannot normally analyze the information of the transponders passing through the road section, and the train running safety is affected.
The information of the experimental transponder and the information of the transponder to be installed are both error information for a normally running train, when the train passes through the transponder, the transponder is activated, and the transponder sends message information to the vehicle-mounted equipment. And the vehicle-mounted equipment receives the message information sent by the responder and analyzes and uses the message information. If the received message information contains unknown information packets or the information packets cannot be analyzed and used, fault parking can be caused in partial scenes, and the train running progress and the running safety can be seriously influenced. In order to reduce the installation work of the transponder without influencing the installation progress or the experimental progress of the transponder, the train is required to be capable of shielding specific transponder information and ensuring the normal running of the train.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, 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.
A transponder information identification method, as shown in fig. 1, comprising the steps of:
the method comprises the following steps: setting beacon mark in the responder message.
And adding a transponder beacon identifier to transponder messages needing shielding, such as experimental transponders, unmounted transponders and the like.
In an existing line, a transponder should contain a transponder message, and a group of transponders consists of 1 to 8 transponders. When all the responder messages in a group of responders are received by the train, the responder messages can be considered to be completely received, and the responder messages consist of message packet headers and information packets.
Specifically, the beacon is identified as a message packet variable, which is added to the transponder message.
In the transponder message, the beacon identifier and the transponder area number containing the beacon identifier are transponder identification information of the transponder to be ignored. The transponder identification information also comprises the effective time of the beacon identification, and the effective time of the beacon identification is timed by the vehicle-mounted equipment and is used when the vehicle-mounted equipment acquires the transponder message containing the beacon identification.
Step two: configuring transponder identification information containing a beacon identification in the vehicle-mounted equipment;
the transponder identification information is configured in the process of starting the train after being electrified, and is specifically stored in a ferroelectric memory of the vehicle-mounted equipment.
The transponder identification information is configured in two ways:
1. by inputting transponder identification information into the in-vehicle apparatus
When the beacon identifier is set in the original transponder message, the specific process of configuring the transponder identification information in the vehicle-mounted device is as follows: and inputting transponder area numbers to be identified, transponder beacon identifications corresponding to the area numbers and effective time of the beacon identifications into the vehicle-mounted equipment.
The area number of the responder is the same as the area number contained in the responder message to be identified; the beacon identification of the responder is the same as the beacon identification set in the responder message;
the valid time of the beacon identifier counts the time of the input of the transponder identification information until the valid time is over.
By adopting the ferroelectric memory of the vehicle-mounted equipment to store the transponder identification information, the effective time that the area number, the beacon identification and the information identification of the transponder can be still stored in the vehicle-mounted equipment after the power is off can be realized, so that the vehicle-mounted equipment can be continuously used after the power is on.
When the beacon mark is arranged in the original message of the transponder, the vehicle-mounted equipment allows a plurality of groups of transponder identification information needing to be identified to be input, and also allows a plurality of groups of transponder identification information to be deleted, so that the omission of the plurality of groups of transponders is supported in the running process of the train. The vehicle-mounted equipment realizes normal reading of the original message of the transponder by the vehicle-mounted equipment by removing the stored area number of the transponder, the beacon identifier and the effective time of the beacon identifier, namely after the transponder identification information in the vehicle-mounted equipment is removed, the vehicle-mounted equipment receives the original message of the transponder, obtains the message information according to a normal message processing program and does not neglect the message.
The operation of inputting the transponder identification information into the vehicle-mounted equipment relates to the functional operation of train safety, in the input process of the transponder identification information, the transponder identification information is sent to the vehicle-mounted host computer through the input interface, the vehicle-mounted host computer inverts the position of an information variable corresponding to the transponder identification information and then sends each variable inverted according to the position to the input interface for modification confirmation, the information is sent to the vehicle-mounted host computer after the input confirmation is carried out again, the vehicle-mounted host computer stores the transponder identification information after judging that the transponder identification information input twice is consistent, and in the subsequent use, the transponder identification information can be accurately changed by adopting the setting of variable inversion and repeated confirmation, and the error of information transmission is avoided.
Illustratively, the transponder identification information is: the method comprises the steps that an area number X1 of a transponder, a beacon identification X2 and beacon identification effective time 12h are input through an input interface, X1, X2 and X12 h are sequentially input through the input interface, a vehicle-mounted host transmits "- [ 12h ] - [ X2 ] - [ X ] 1' to the input interface after adopting reverse setting, and stores X1, X2 and X12 h in a ferroelectric memory after being confirmed again, and the information is used when a train receives a message of the transponder to be identified.
Because the area numbers of all groups of transponders are different and the identification information of each group of transponders is also different, the vehicle-mounted equipment can store a plurality of groups of transponder identification information and respectively neglects the messages which accord with the transponder identification information in the running process of the train.
2. Setting the transponder identification information in the identification information packet, setting the identification information packet in the demand transponder, receiving the identification information packet when the train passes through the demand transponder, and extracting the transponder identification information.
And adding a new information packet in the demand responder for the train to pass through, wherein the information packet is used as an identification information packet, and the beacon identification is arranged in the information packet. The identification information packet is used for identifying the information of the transponder to be ignored, which is positioned behind the demand transponder, and the beacon identifier set in the transponder message of the transponder to be ignored is the same as the beacon identifier in the identification information packet. The identification information packet also comprises other responder identification information and addition/deletion attribute information, wherein the other responder identification information is a responder area number and beacon identification effective time.
The responder area number is the responder area number of the responder to be ignored;
the beacon mark is a beacon mark arranged in a transponder message to be ignored;
the effective time of the beacon identification is the time when the train receives the identification information packet, and the effective time is up;
the add/delete attribute information facilitates the deletion or addition setting of the identification packet and the transponder identification information.
After the identification information packet is set, the vehicle-mounted equipment can confirm whether to use the identification information packet according to the driving requirement. Specifically, before the train runs, the identification information packet is set in the demand responder, if the vehicle-mounted equipment is configured to use the identification information packet, when the train passes through the demand responder, the vehicle-mounted equipment receives the identification information packet, further identifies the responder identification information in the identification information packet, and stores the responder identification information into the ferroelectric memory; if the vehicle-mounted equipment is configured not to use the identification information packet, the vehicle-mounted equipment ignores the identification information packet after receiving the identification information packet when the vehicle-mounted equipment passes through the demand responder.
In the running process of the train, demand information corresponding to the train can be configured according to the running demand, a required information packet can be stored in a demand responder, and the demand information can contain the road condition of the train passing subsequently. When the train is configured to use the demand information, the train receives the information sent by the demand responder and processes the information; when the train is configured not to use the demand information, the information is accepted and ignored. In the invention, the identification information packet is stored in the demand responder, and the train is configured to receive and process the identification information packet, otherwise, the identification information packet is ignored after being received.
When a train passes through a demand responder containing an identification information packet, if other message contents are set in the demand responder, the train can simultaneously receive the identification information packet and other messages when passing through the demand responder. If the train is configured not to use the identification information packet, the train ignores the identification information packet but continues to decode other messages, and if the train is configured to use the identification information packet, the train sequentially reads the identification information packet and other message contents.
Wherein, in the train running direction, the to-be-ignored transponder is arranged at a position behind the demand transponder and the train needs to pass through later.
If the train needs to identify multiple groups of transponders, the configuration modes of the transponder identification information can be used in a combined manner, for example, a beacon identification is set in an original message of the transponder by a part of the transponder to be ignored, and beacon identifications of other transponder groups to be ignored are set in a transponder identification information packet.
Step three: and the vehicle-mounted equipment identifies the transponder according to the transponder identification information and shields the information sent by the transponder.
When the train passes through the transponder to be ignored, the train can receive the transponder message containing the transponder identification information, and the vehicle-mounted equipment can call the transponder identification information stored in the train to compare with the received transponder message information: if the transponder identification information stored in the vehicle-mounted equipment is consistent with the received transponder message information, the received transponder message or information packet is a transponder message which needs to be ignored, and the vehicle-mounted equipment ignores the transponder message; if the transponder identification information stored in the vehicle-mounted equipment is inconsistent with the received transponder identification information, the received transponder message is not the transponder message which needs to be ignored, and the vehicle-mounted equipment can normally use the transponder message.
The in-vehicle device judging whether the stored transponder identification information is consistent with the received transponder identification information includes the following processes:
the beacon mark is arranged in the responder message to be ignored, and the train receives the responder message, acquires the area number and the beacon mark of the responder in the message and records the time for acquiring the message. And comparing the area number of the responder and the beacon identification in the message with the area number of the responder and the beacon identification stored in the vehicle-mounted equipment, judging whether the area number of the responder and the beacon identification are consistent, and judging whether the time for acquiring the message exceeds the effective time of the beacon identification.
And if the receiving time of the transponder message is within the effective time range of the beacon identification, ignoring the transponder message.
If any one of the area number and the beacon identification of the responder in the message is inconsistent with the vehicle-mounted storage information, ignoring the responder message; if the message receiving time recorded by the vehicle-mounted equipment exceeds the effective time of the beacon identification stored in the vehicle-mounted equipment, the vehicle-mounted equipment can still normally use the received transponder message even if the area number of the transponder in the message is consistent with the beacon identification.
When all the vehicle-mounted equipment does not need to ignore the responder message containing the beacon identifier, the identification information packet in the demand responder can be modified, and the responder area number and the beacon identifier stored in the vehicle-mounted equipment as well as the effective time information of the identifier are deleted.
The transponder that can ignore and the transponder that needs are distinguished through transponder identification information such as beacon sign, avoid often dismantling the transponder, all can not cause the influence to existing circuit in transponder group transformation and transponder group experimentation, guarantee the normal driving and the driving safety of train.
In the transponder information identification method, the transponder identification information in the vehicle-mounted equipment is configured in different modes, and the configuration mode of inputting the transponder identification information has high flexibility, so that the specific beacon-related information can be set or removed for a specific vehicle when a train is started, but when a large amount of beacon identification information needs to be set/removed, the safety risk of inputting errors easily exists. The mode of configuring the transponder identification information by the identification information packet can avoid the security risk of inputting errors, but the message information in the required transponder group needs to be changed, so that the flexibility is poor. Therefore, in the implementation process of the invention, the specific settings of the storage content, the installation place and the like of the transponder are ignored according to the needs, such as: the method comprises the steps that information content stored in a demand responder is more, the installation place is more complex, responder identification information such as beacon identification is directly input into vehicle-mounted equipment, and if the demand responder contains less information content and the installation place is simple, responder messages in the demand responder are modified, and identification information packets are added.
The invention also relates to a transponder identification system, as shown in fig. 2, comprising: the device comprises a beacon identifier setting module, a vehicle-mounted equipment input module and a vehicle-mounted equipment judgment module.
The beacon identification setting module is connected with the vehicle-mounted equipment input module, and the vehicle-mounted equipment input module is connected with the vehicle-mounted equipment judgment module.
The beacon mark setting module is used for setting beacon marks in responder information, and the responder information comprises responder message information and responder mark information packets.
Specifically, the beacon identifier is a message packet variable.
The beacon identification setting module sets the beacon identification in the message of the transponder to be ignored, and the beacon identification is a message packet variable.
In the transponder message, the beacon identifier and the transponder area number containing the beacon identifier are transponder identification information of the transponder to be ignored. The transponder identification information also comprises the effective time of the beacon identification, the effective time of the beacon identification is timed by the vehicle-mounted equipment, and the transponder identification information is called and used when the vehicle-mounted equipment acquires the transponder message containing the beacon identification.
The vehicle-mounted equipment input module is used for configuring the transponder identification information containing the beacon identification in the vehicle-mounted equipment.
The vehicle-mounted equipment input module is configured in the following two ways:
the vehicle-mounted equipment input module inputs the transponder identification information into the vehicle-mounted equipment;
and the vehicle-mounted equipment input module extracts the transponder identification information from the identification information packet to the vehicle-mounted equipment when the train acquires the identification information packet containing the transponder identification information.
The in-vehicle apparatus stores the transponder identification information into the ferroelectric memory.
The vehicle-mounted equipment input module inputs the transponder identification information into the vehicle-mounted equipment:
the vehicle-mounted equipment input module sequentially inputs the transponder area number, the transponder beacon identification and the effective time of the beacon identification in the transponder identification information into the vehicle-mounted equipment and stores the transponder area number, the transponder beacon identification and the effective time of the beacon identification.
The effective time of the beacon mark starts to time from the input of the transponder identification information into the vehicle-mounted equipment, and the timing range is the effective time of the beacon mark until the effective time is over.
The vehicle-mounted equipment input module allows a plurality of groups of transponder identification information to be identified to be input, and also allows a plurality of groups of transponder identification information to be deleted, so that the omission of a plurality of groups of transponders is supported in the running process of a train.
In the process that the input module of the vehicle-mounted equipment inputs the identification information of the responder, the position of an information variable corresponding to the identification information of the responder is inverted, then each variable is inverted according to the position and sent to the input module of the vehicle-mounted equipment for modification confirmation, the modification confirmation is carried out, the modification confirmation is sent to the vehicle-mounted host after the input confirmation of the input module of the vehicle-mounted equipment is carried out again, and the identification information of the responder is stored after the identification information of the responder input twice is judged to be consistent.
The vehicle-mounted equipment input module extracts the identification information of the transponder from the identification information packet into the vehicle-mounted equipment:

The responder area number is the responder area number of the responder to be ignored;
the beacon mark is a beacon mark arranged in a transponder message to be ignored;
the beacon mark effective time is the time when the train receives the mark information packet, and the beacon mark effective time is counted until the effective time is over.
If the vehicle-mounted equipment is configured not to use the identification information packet, the vehicle-mounted equipment ignores the identification information packet after receiving the identification information packet when the vehicle-mounted equipment passes through the demand responder.
And the vehicle-mounted equipment judgment module is used for identifying the responder according to the responder identification information and shielding the information sent by the responder.
When the train passes through the transponder to be ignored, the vehicle-mounted equipment judgment module can call the transponder identification information stored in the vehicle-mounted equipment judgment module to be matched with the received transponder message information:
