Train tail information transmission system for train

Abstract

The invention provides a train tail information transmission system for a train. The system comprises a train head on-board module, a train tail on-board module and a ground train tail register server, wherein the train head on-board module is positioned at the head of the train; the train tail on-board module is positioned at the tail of the train; the ground train tail register server is communicated with the train head on-board module and the train tail on-board module through a WiMAX (Worldwide Interoperability for Microwave Access) network and is used for establishing a unique corresponding relation between the train head on-board module and the train tail on-board module before the train head on-board module and the train tail on-board module are communicated; and the train tail on-board module is used for acquiring train tail information and sending the train tail information to the train head on-board module through the WiMAX network. In the invention, the WiMAX network based on an OFDM/OFDMA (Orthogonal Frequency Division Multiplexing/Orthogonal Frequency Division Multiplexing Access) packet switching technology is applied to train tail information transmission for the first time, the problem that the effect of transmitting train tail wind pressure information traditionally by adopting a radio station is influenced by the train length can be solved, meanwhile, conditions for developing other train dedicated businesses at the tail of the train by utilizing the WiMAX network are created.

Description

technical field [0001] The invention relates to the field of network technology, and in particular to a train tail information transmission system. Background technique [0002] During the operation of railway trains in my country, the wind pressure value at the rear of the train is an important reference data for the safe operation of the train, especially in long and heavy-duty trains, whether the wind pressure information at the rear of the train is normal or not will directly affect the control of the train. motion effect. The current tail information transmission system uses a 400MHz+400KHz radio station to connect the traction locomotive query equipment and the wind pressure test equipment at the rear of the train one-to-one, so that the traction locomotive query equipment can obtain the wind pressure measured by the wind pressure test equipment in real time. pressure value. The train tail information transmission system is more effective for short-distance trains, bu...

Problems solved by technology

[0003] In order to overcome the defect that the tail information transmission system in the prior art cannot timely transmit the tail wind pressure information to the traction locomotive for long and heavy-duty trains, the present invention provides a kind of transmission of the tail information that is not affected by the length of the train and the running process of the train. Column Tail Information Transmission System Restricted by Medium Geographical Environment

[0005] The present invention applies the WiMAX network based on OFDM / OFDMA packet switching technology to the transmission of tail information for the first time, and can solve the problem that the traditional use of wireless stations to transmit wind pressure information at the tail of the train is affected by the length of the train. The development of other exclusive railway business at the rear of the train creates conditions
