Description

Technical Field

[0001] The invention relates to the technical field of railway traffic command and dispatch, in particular to a portable GSM-R handheld station functional number dispatching system. Background Art

[0002] During the operation of railway trains, communication signals play a very important role in the command and dispatch of trains, and have an important impact on the safe and orderly operation of trains. my country's high-speed railways use the CTCS-3 train control system (referred to as C3 train control system) to control trains. The system consists of on-board equipment, GSM-R network and ground equipment. As part of the train control system, the GSM-R network carries the transmission of the train control system and provides a two-way information exchange channel between the on-board equipment and the radio block center (RBC). The on-board equipment receives information such as driving permits, temporary speed limits and line parameters issued by the RBC through the GSM-R network; the RBC receives train dynamic information (such as train speed, position, etc.) transmitted by the on-board equipment through the GSM-R network. The train wireless dispatching telephone of China Railway is used by dispatchers and station attendants to dispatch and command train drivers and train drivers along the line. The stations along the railway are distributed in strips across the country. Each station is equipped with a low-power radio station and switching device, and the locomotive is equipped with a radio station and a control box. The dispatcher connects with the station radio (or fixed radio) through wired or wireless lines, and then the station radio (or fixed radio) connects with the locomotive radio within its field coverage area through a wireless channel, thus enabling communication between the dispatcher and the driver and between the station duty officer and the driver.

[0003] In the current railway communication system, station attendants are equipped with FAS dispatch desks and GSM-R handheld terminals, among which the FAS dispatch desk is mainly used to talk with train drivers, issue and adjust dispatch orders. Relatively speaking, the dispatching function of the GSM-R handheld terminal is not commonly used, and station attendants are not familiar with its operation. Similar situations also exist internationally. In this context, the present invention is at the forefront of research both at home and abroad, and the research focus at home and abroad is on improving the overall efficiency and user-friendliness of railway communication systems. At present, the international communication system is mainly integrated on the FAS dispatch desk commonly used by dispatchers, while the dispatching function of the GSM-R handheld terminal is less concerned. In order to further improve efficiency and ease of operation, the present invention aims to solve the problem that dispatchers are unfamiliar with the operation of the GSM-R handheld terminal, and improve the flexibility and ease of operation of the entire dispatching system.

[0004] Therefore, we have developed a new portable GSM-R handheld station functional number dispatching system. Summary of the invention
