Description
Technical Field
The invention relates to a train control system, in particular to a processing method for improving the precautionary capacity of a CTCS-3 level train control system.
Background
The design specification of high-speed railway (TB10621-2014) specifies that the effective length of a departure line of the high-speed railway is 650m, the length of a platform is 450m, the length of a train is 430m, and a station departure signal machine through which a high-speed train passes is generally arranged at a position which is not less than 55m away from a police mark or not less than 50m away from the tip of the nearest opposite switch point. The general situation of the arrangement of the station track length, the platform, the outbound signal machine and the transponder group of the CTCS-3 level train control system is shown in figure 1.
And by combining the safety distance requirements of the CTCS-3 and the compatible CTCS-2 level train control system, the stop sign from the station to the departure line is generally arranged about 75m away from the outbound signal and about 20m away from the end of the station platform in standard arrangement. When the CTCS-3 vehicle-mounted equipment controls the vehicle, the distance between the mobile authorization EOA end point and the signal machine is generally 20-30m, and the distance between the mobile authorization EOA end point and the dangerous point DP alarm mark is 75-85 m.
An outbound transponder group 20m away from a train signal machine of a CTCS-3 level train control system station is characterized in that when an access path protected by the train signal machine is not established and the train signal machine is not opened, an active transponder in the transponder group is controlled by station train control center equipment TCC to send an absolute parking (CTCS-5) packet, a shunting danger (ETCS-132) packet and a visual driving danger (ETCS-137) packet.
According to technical conditions of CTCS-3 level train control vehicle-mounted equipment (TB/T3483-2017), triggering emergency braking to stop when the vehicle-mounted equipment of the CTCS-3 level train control system receives train dispatching danger messages (ETCS-132) and visual train dispatching danger messages (ETCS-137) in a visual train dispatching mode OS and a train dispatching mode SH; however, in the CTCS-3 level full monitoring mode FS and the guidance mode C0, the vehicle-mounted device does not respond to [ CTCS-5 ], [ ETCS-132 ], and [ ETCS-137 ]. If the train is falsely introduced into the signal machine due to reasons, the messages of [ CTCS-5 ], [ ETCS-132 ] and [ ETCS-137 ] cannot be output as the CTCS-2 level train control system because the messages of the FS and the C0 which are completely monitored by the CTCS-3 level train control system and the guidance mode are not identified, and a safety defense line for preventing the falsely introduced signal is omitted compared with the CTCS-2 level train control system.
For a station for running 17 marshalling motor train units by using an existing station track, the length of the 17 marshalling motor train units is close to 440m, and under the condition of maintaining the existing design specifications and equipment technical conditions, for an arrival-departure line with an effective length of 650m, a stop sign needs to be arranged at a position 20m away from a platform end, and then the tail of the vehicle cannot stop in the platform area by about 10 m.
Under the condition of not changing the effective length of the station track, one possible measure is to move the outbound signal machine outwards, so that the stop sign can be arranged within a range of 0-10m from the station platform end, and the tail of the vehicle can be ensured to enter the station platform area. According to the relevant definition of the ETCS (European train control system) requirement specification, the position of a physical danger point DP (warning mark) for stopping the train at the outbound signal machine is a post-turnout warning mark, and the train can not collide with other trains without rushing into the warning mark in principle. And (3) moving the outbound signal machine outwards, wherein the CTCS-3-level train control vehicle-mounted equipment does not have the capability of receiving the message output brake of the transponder, which is equivalent to reducing the distance from EOA to DP, namely reducing the safety protection allowance provided by the whole railway system for the train.
The length of the track circuit outside the signal machine meets the requirement of train control vehicle-mounted response time on one hand to realize the requirement of the minimum length of the track circuit and normal action of vehicle-mounted equipment, and is not greater than the distance between a parking mark and the signal machine leaving the station on the other hand to ensure that a train cannot break into the signal machine when the train normally parks; or the technical method that the induction loop is arranged outside the outbound signal machine and the induction loop sends the H code when the signal machine is not opened is adopted, the method changes the medium for sending the H code on the vehicle from the ground to the induction loop from a track circuit, and other principles are the same as the scheme. Although the technical means improve the safety protection capability of the train in the CTCS-3 level train control system complete monitoring mode FS, and trigger the braking function when the distance between the vehicle-mounted equipment and the DP is increased by a certain distance, the problem of the train intrusion protection function in the CTCS-3 level train control system CO mode is not solved; in addition, a ground track circuit or an induction loop needs to be added, so that the equipment investment and the maintenance workload are increased; when the track circuit equipment is in failure, the normal transportation is easily affected.

In the embodiment, the absolute stop message [ CTCS-5 ] packet configured in the outbound transponder group is fully utilized, and the CTCS-3-level train control vehicle-mounted equipment is newly added with the processing flow of the [ CTCS-5 ] message in the outbound transponder group under the FS mode and the CO mode, so that the train can send an emergency stop instruction according to the [ CTCS-5 ] message, an emergency brake is output when the train passes over an unopened train annunciator active transponder group, and the safety precaution capacity of the CTCS-3-level train control system on the fault of the railway station train annunciator is improved. In the embodiment, only the ATP vehicle-mounted equipment software of the CTCS-3 level train control is required to be modified, and the logic for identifying and processing the ground active transponder (CTCS-5) packet by the CTCS-3 level train control vehicle-mounted equipment in FS and CO modes is increased, so that the cost is low, and the practicability is high.
At the current CTCS-3 level train control system station, the outbound signal responder group is arranged 75m away from the dangerous point DP police mark, and the ground equipment can not be modified.
Referring to fig. 2, in the FS mode, the CTCS-3 train control onboard device determines whether the received outbound transponder group message includes [ ETCS-41 ], [ ETCS-42 ], [ ETCS-72 ], [ ETCS-79 ], and [ ETCS-131 ], and executes a corresponding instruction if the outbound transponder group message includes [ CTCS-5 ], and the onboard device continues to determine whether the outbound transponder group message includes the [ CTCS-5 ] message if the outbound transponder group message includes the [ CTCS-5 ] message and executes an emergency stop instruction, and of course, the logic processing flow between the onboard device and the outbound transponder group ends if the outbound transponder group message does not include the [ CTCS-5 ]. Referring to fig. 2, in the CO mode, the CTCS-3-level train control on-board device determines whether a received outbound transponder group message includes [ ETCS-41 ], [ ETCS-42 ], [ ETCS-79 ], and [ ETCS-131 ], and executes a corresponding instruction when the outbound transponder group message includes the [ CTCS-5 ] message, and if the outbound transponder group message includes the [ CTCS-5 ] message, the on-board device identifies and processes the message and executes an emergency stop instruction, and certainly, if the outbound transponder group message does not include the [ CTCS-5 ] message, a logic processing flow between the on-board device and the outbound transponder group is finished.
