With reference to fig. 1 to 4, the present embodiment provides a method and a tool for generating and using an offline message of an active transponder, which are used in a train control center of a CTCS-2 level train control system.
The working principle is as follows:
the CTCS-2 level train control system comprises ground equipment and vehicle-mounted equipment. The ground equipment is shown in fig. 1, and includes a train control center, a temporary speed limit server, ground electronic equipment (LEU), an active transponder, and the like. The temporary speed limit server generates a temporary speed limit command and sends the temporary speed limit command to the column control center, and the column control center generates an active responder message according to the track section state information and the temporary speed limit command and sends the active responder message to the LEU. Active transponders are usually arranged at the station entry end and the station exit end and are connected to the LEU by a cable, and the LEU transmits the received active transponder messages to the active transponders by the cable. The active transponder is in a dormant state at ordinary times, when a train passes above the active transponder, the active transponder receives electromagnetic energy transmitted by the vehicle-mounted antenna, converts the electromagnetic energy into electric energy to enable a transmitting circuit in the active transponder to work, and sends messages of the active transponder to the train in a circulating and real-time mode until the electric energy disappears.
The method and tool provided by this embodiment pre-calculate routes within the administrative scope of the train control center according to different temporary speed limit positions and speed limit levels to generate multiple sets of static data including offline messages and index information. And then, the train control center calculates triggered index information according to the actually triggered route and speed limit level, and extracts the corresponding off-line message to output to the LEU for use.
As shown in fig. 2, this embodiment provides a method for generating an offline message of an active transponder, which is used in a train control center of a CTCS-2-level train control system, where the train control center includes retrievable basic line data, (where the basic line data includes a transponder position table, a route information table, a line speed table, and the like, and the basic line data in this embodiment refers to basic line data within a scope governed by the train control center), and includes the steps of:
s1, setting a responder retrieval type and an access retrieval type; wherein, the first and the second end of the pipe are connected with each other,
the transponder search type can be set to inbound transponders (JZ/FJZ), outbound transponders (CZ/FCZ) and the like;
the route search type may be set to various lateral pick-up routes of an inbound transponder, various lateral departure routes of an outbound transponder, or the like. Among them, the type of lateral pick-up approach of the inbound transponder generally includes: a lateral pick-up-1, as shown in fig. 4a, refers to a lateral pick-up approach without a straight stock departure condition for JZ access; a reverse lateral pick-up-1, as shown in fig. 4b, refers to a lateral pick-up approach with FJZ access and no straight stock departure condition; a lateral pick-up-2, as shown in fig. 4c, refers to a lateral pick-up approach with a forward straight run departure condition (exit from FJZ); a reverse lateral pick-up-2, as shown in fig. 4d, refers to a lateral pick-up approach with FJZ cut-in and forward straight run-out conditions (run-out from FJZ); a lateral pick-up-car-3, as shown in fig. 4e, refers to a lateral pick-up approach with a reverse straight stock departure condition (exit from JZ); the reverse lateral pick-up-3, as shown in fig. 4f, refers to a lateral pick-up approach with a reverse straight run departure condition (exit from JZ) for FJZ pick-up. The various types of lateral departure approaches for outbound transponders are generally similar to the various lateral pick-up approaches for inbound transponders described above.

if a conforming responder is searched, stopping traversal, and marking the responder as a target responder, namely, turning to the step S3 for subsequent processing;
if the traversing is finished and the corresponding responder is not searched, quitting;
s3, traversing the route information table of the basic route data according to the set route retrieval type and the target responder, and retrieving whether a matched route exists:

the quantity of the offline messages can be determined according to the V _ TSR value, and the formula is as follows:
the number of offline messages =1+ (V _ TSR-9+ 1) x 3;
the principle is as follows: aiming at a target route, 4 conditions of temporary speed limit positions need to be distinguished to generate an offline message, wherein the four conditions are as follows: (1) no temporary speed limit exists on a target access, (2) temporary speed limit exists on the target access and between a transponder and a signal machine, (3) temporary speed limit exists only on the target access, (4) temporary speed limit exists only between the transponder and the signal machine; according to the requirements of technical conditions of QCR 817-2021 column control centers, 1 item of offline message without speed limit on a marked road needs to be generated under the condition (1), and 1 item of offline message needs to be generated for each speed limit level under the conditions (2) - (4) in a speed limit interval of a target route; because the lowest temporary speed limit level of the CTCS-2 level train control system is 9 levels, and the highest speed limit level of the target access is V _ TSR level, the speed limit interval of the target access is 9 levels to V _ TSR levels, so that V _ TSR-9+1 offline messages need to be generated in each of the situations (2) - (4).

s422, generating (2) an offline message and corresponding index information under the condition that temporary speed limit exists on a target route and between a responder and an annunciator simultaneously based on the V _ TSR; the method comprises the following steps:
from speed level 9 to V _ TSR, generating 1 offline message in each speed level; generating corresponding index information which comprises a target route number and an index number, wherein the target route number is the number of the current target route, and the index number is 2- (V _ TSR-9+ 1) +1;
s423, based on the V _ TSR, generating (3) an offline message and corresponding index information only when the temporary speed limit exists on the target access; the method comprises the following steps:
from speed level 9 to V _ TSR, generating 1 offline message for each speed level; generating corresponding index information, including a target route number and an index number, wherein the target route number is the number of the current target route, and the index number is (V _ TSR-9+ 1) +2 to (V _ TSR-9+ 1) × 2+1;

s43, checking each offline message and index information; in particular to a method for preparing a high-performance nano-silver alloy,
and (4) checking each offline message and index information generated in the step (S42) according to the method in the prior art, and judging whether the offline messages and the index information are correct:
if yes, returning to the step S3, and continuing the route traversal from the previous pause traversal position;
otherwise, returning to step S41, and calculating and checking the current target route again.
