1. A data processing method based on an automatic identification system, the method comprising:
receiving, by a virtual station container, a data request sent by a poller, wherein the virtual station container contains at least two virtual stations, and successively checking whether or not each virtual station in the virtual station container has to-be-sent data in a current timeslot, wherein any virtual station of the at least two virtual stations comprises a virtual timeslot allocation logic (TAL) device;
reading, when a first virtual station has to-be-sent data in the current timeslot, by the virtual station container, the to-be-sent data in the first virtual station, and sending the read data to a transmitter;
wherein the virtual station further comprises a navigation state cache (NSC) device corresponding to the virtual TAL device;
wherein reading, when the first virtual station has to-be-sent data in the current timeslot, by the virtual station container, the to-be-sent data in the first virtual station, and sending the read data to the transmitter comprises:
when a first virtual TAL device in the first virtual station has to-be-sent data in the current timeslot, sending, by the virtual station container, an identifier of the first virtual TAL device to the poller,
receiving, by the virtual station container, an instruction of reading data in a NSC device corresponding to the first virtual TAL device, wherein the instruction is sent by the poller, and
reading, by the virtual station container, the data in the NSC device according to the instruction, performing packet encoding on the data in the NSC device, and sending an encoded data packet to the transmitter.
