Abstract: Based on 4G special network (station and train interaction network) and railway integrated information network, this paper studied the wireless interaction technology of station and train under the condition of mobile interconnection. Based on the wireless interaction technology, the railway luggage and parcel information system would have the conditions of network interconnection, data reasonable connection and infrastructure sharing with the railway passenger transport information system. Relying on the safety platform of China Railway, sharing the station and train interaction network with the railway ticketing and reservation system, the paper put forward the network architecture of wireless interaction of luggage and parcel system, clarified the content and frequency of data interaction, adopted the unified data interface specification and interface standard, and gave the interactive information security strategy. Through the business data interaction experiment of some train numbers and luggage and parcel handling points of Beijing Shanghai Railway Line, it is verified the feasibility of wireless interaction of station and train based on 4G special network, and improved the wireless interaction level of railway baggage information system to a certain extent.
