Embodiment Construction

[0075] Transponder message format:

[0076] Before coding, the transponder message stores 830 bits of user information message, and the frame format of the message is shown in the attached drawing of the manual figure 2 : Among them, the user information package includes: (1) Transponder link [ETCS-5], see the accompanying drawing in the manual image 3 ;(2) Line slope [ETCS-21], see attached drawing Figure 4 ;(3) Line speed [ETCS-27], see the attached drawing of the manual Figure 5 ;(4) Grade conversion [ETCS-41], see the attached drawing of the manual Figure 6 ; (5) CTCS data [ETCS-44], see the accompanying drawings Figure 7 ;(6) Special section [ETCS-68], see attached drawing Figure 8 ; (7) Shunting hazard [ETCS-132], see the attached drawing of the manual Figure 9 ;(8) Track section [CTCS-1], see attached drawing Figure 10 ; (9) Temporary speed limit [CTCS-2], see the attached drawing of the manual Figure 11 ;(10) Interval reverse operation [CTCS-3], see at...

Abstract

A train control dynamic message coding method can reduce the message coding links in the design stage and save message storage space and omit part of the links of message management to promote the running efficiency of train. The technical proposal is that the method comprises the following steps of dynamic coding design and responder message processing; the dynamic coding design comprises the following steps in specific that the system is collocated with a datasheet; a station static datasheet, a route measurement table, a track sectional table, a responder location table and a long-short linked list are processed; based on the station route condition and responder location, the correspondence between the responder and the route is established and every responder is separately corresponding to difference route and forms circuit parameter packets according to the design principle; the parameter packets comprise a responder link packet, a circuit velocity packet, a circuit slope packet, a track sectional packet, a reverse operational packet, a large-sized switch packet and a shunting danger packet.

Description

technical field [0001] The invention belongs to the field of message methods in train control centers, in particular to a method of changing the static coding, storage, and selective transmission of existing train control centers into dynamic coding, which can reduce the number of message coding links in the design stage and save A dynamic message encoding method for a train control system that saves space for message storage and omits part of message management, thereby improving train operation efficiency. Background technique [0002] In the CTCS-2 train control system, the station train control center transmits message information to the balise in real time according to the route conditions and temporary speed limit conditions, and completes the information transmission between the train and the ground through the balise. Transponder messages are secure messages that are encrypted according to European transponder coding principles. [0003] At present, the commonly use...
