Abstract
The invention discloses an AIS (Automatic Identification System) dual-mode communication method and an AIS dual-mode communication terminals for ships and aims at the defect that the existing AIS terminal cannot meet the requirement on ships and shipping company safety supervision, production scheduling and information interaction. The AIS dual-mode communication method comprises the following steps that: a control module of a first AIS terminal transmits AIS data to a TDMA (Time Division Multiple Address) module and a CDMA (Code Division Multiple Access) module of the first AIS terminal; the TDMA module and the CDMA module of the first AIS terminal send the AIS data; and a TDMA module of a second AIS terminal receives the AIS data and transmits the AIS data to a control module of the second AIS terminal. According to the AIS dual-mode communication method and the AIS dual-mode communication terminals, the requirement on information interaction can be effectively met and the construction of a complete inland river navigation comprehensive information service platform has the technical effect of a communication network foundation.

The TDMA module at said the 2nd AIS terminal is given said AIS transfer of data the control module at the 2nd AIS terminal.
Further, said AIS data comprise the GPS information at an AIS terminal.
Further, the display module that the control module at a said AIS terminal drives an AIS terminal shows said AIS data,
The display module that the control module at said the 2nd AIS terminal drives the 2nd AIS terminal shows said AIS data.
In order to solve the problems of the technologies described above, the ship automatic identification system double-mode communication terminal comprises,
Control module is used to transmit the AIS data and gives TDMA module and CDMA module, and obtains the AIS data from said TDMA module,
The TDMA module is used for reception/transmission AIS data,
The CDMA module is used to send the AIS data.
Further, control module also is used to drive display module,
Said display module is used to show said AIS data.
Further, said CDMA module adopts USB interface to be connected with said control module.
Said CDMA module adopts WCDMA, CDMA2000 or TD-SCDMA standard to send the AIS data.
By on can know; The inventive method and terminal can realize that AIS possesses TDMA and CDMA ability to communicate simultaneously; Reach boats and ships and can realize automatic recognition function, can satisfy functions such as ship production scheduling and information interaction again, the AIS terminal has the characteristics of two kinds of communication networks simultaneously; Can effectively solve navigation safety and produce needs, make the construction of whole inland water transport integrated information service platform have the technique effect on communication network basis.
