The product has passed the functional verification of various scenarios of fully automatic driving and the third-party safety assessment, and has met the technical requirements of GoA4, which is a new breakthrough in the field of fully automatic driving technology of rail transit. On the terminal equipment, Panda Information has added the currently popular intelligent customer service equipment for the north section of Nanjing Metro Line 7. Through self-service operation, passengers can realize human-computer dialogue, conduct ticket analysis, query, online payment, Internet refund, transaction query, etc., and also can query the online map, train operation time, ticket price list, station navigation, transfer query, metro business, metro surrounding information, etc. Further improve the metro experience and improve travel efficiency of Nanjing citizens.

On the one hand, a query machine system platform has been established in Nanjing Metro to provide data processing capability for Nanjing Metro query machine and other equipment; On the other hand, the new network standard of Nanjing Metro is adopted for construction. The new standard is upgraded from the original network standard, which greatly improves the real-time of data and is compatible with existing systems.
