Problems solved by technology

The system transmits the ground information to the locomotive by sensing the information in the track circuit. Since there is only one-way information transmission from the ground to the locomotive, the ground cannot get information about the train's position, speed and running status.
At the same time, the train control instructions on the ground cannot be confirmed by the on-board equipment, and the reliability of its data transmission cannot be guaranteed, which will adversely affect the safe operation of the train
In addition, the track circuit used in the existing signal system will be affected by the length of the rail, ballast resistance, climate and surrounding environment, and the speed of information transmission, signal quality and information volume have relatively large limitations
Moreover, the system requires a lot of outdoor equipment and cables, and the workload of manual maintenance is quite large

Abstract

This invention discloses a method for safely transmitting sigal data of wireless locomotives including a wireless transmission channel structure and a safety transmission protocol, in which, the transmitting channels can be two modes of digital transmission broadcast stations and GSM-R: 1, since the data channel structure of the digital transmission broadcast stations is composed of a dynamic networking, a star structure, a mode of frequency alternation between stations and address selection, a transmission way and a communication protocol, it solves the problem of interference of same frequencies, conflict of transmission frames, locking the broadcast stations, signal covering, hand off and communication protocols, 2, based on the structure of the data transmission channel of the GSM-R digital mobile communication channel, the access way of loading and the ground devices and device interfaces, 3, related transmission protocol, 3-D control and signal response confirmation can secure the reliable and safe transmission.

Description

Technical field: [0001] The invention relates to a data transmission method, in particular to a method for transmitting data in a wireless channel mode in a railway locomotive signal system to realize safe transmission of locomotive signal data; it belongs to the field of railway signal technology. Background technique: [0002] The existing locomotive signaling system in our country is mainly a continuous or near-continuous signaling system based on the ground track circuit. The system transmits the ground information to the locomotive by sensing the information in the track circuit. Since there is only one-way information transmission from the ground to the locomotive, the ground cannot get information about the train's position, speed and running status. At the same time, the train control command on the ground cannot be confirmed by the on-board equipment, and the reliability of its data transmission cannot be guaranteed, which will adversely affect the safe operation of...
