Embodiment 1

[0021] This embodiment adopts a conventional software radio scheme, such as figure 1 As shown, the system includes: an antenna group 1, a radio frequency conversion group 2 connected to the antenna group 1, a high-speed data processing board 3 connected to the radio frequency conversion group 2, a microcomputer (workstation) data processing platform 4 connected to the high-speed data processing board 3 and a display Console 502 . Antenna group 1 is used to send and receive communication radio frequency signals and navigation radio frequency signals. Radio frequency conversion group 2 converts radio frequency signals received by antenna group 1 into intermediate frequency signals or converts intermediate frequency The data processing board 3 processes the intermediate frequency signal converted by the radio frequency conversion group 2, and after converting the analog / digital signal, the microcomputer (workstation) data processing platform 4 performs comprehensive processing of...

Embodiment 2

[0029] This embodiment adopts a virtual radio scheme, such as figure 2 As shown, the difference in Embodiment 1 is that the high-speed data processing board 3 only includes two bandwidth conversion A / D / A modules 301, and does not include the software radio application program set 303 integrated in the embedded operating system 3031; the microcomputer ( Workstation) The data processing platform 4 also includes a software radio application program set 402; the general operating system software 401 also includes a general bus interface 4011, and the rest of the parts are the same.

[0030] In the second embodiment, the digital signals respectively processed by the two bandwidth conversion A / D / A modules 301 are directly sent to the SDR application set 402 through the communication interface 406 under the control of the general operating system software 401 . The function realized by the software radio application program set 402 is the same as that of the software radio applicati...

Abstract

The invention discloses a software-radio-based intelligent bridge system for a ship. The system comprises an antenna group, a radio frequency conversion group connected with the antenna group, a high-speed data processing board connected with the radio frequency conversion group, a microcomputer data processing platform connected with the high-speed data processing board, and a display console, wherein the antenna group is used for transmitting and receiving a communication radio frequency signal and a navigation radio frequency signal; the radio frequency conversion group converts a radio frequency signal received by the antenna group into an intermediate frequency signal, or converts an intermediate frequency signal to be transmitted by the high-speed data processing board into the radio frequency signal; the high-speed data processing board processes the intermediate frequency signal converted by the radio frequency conversion group, and performs the conversion of an analogue/digital signal; the microcomputer data processing platform comprehensively processes navigation information according to the converted digital signal, and displays information required by a navigator and a manual operation instruction; and the high-speed data processing board is connected with the microcomputer data processing platform directly through a system bus. An external network connection mode adopted by the conventional integrated bridge system for the ship is replaced by a system bus mode, so that the execution efficiency of the system is high.

Description

technical field [0001] The invention belongs to the technical field of ship navigation and communication, in particular to a ship intelligent bridge system based on software radio. Background technique [0002] With the continuous advancement of science and technology, ship communication and navigation equipment has been developed rapidly, and various navigation aid technologies or systems such as VTS, GPS, ENC, ECDIS, and AIS have emerged one after another, providing mariners with a wealth of navigation aids. However, there are still some problems in the emergence and application of these navigation technologies: firstly, various navigation and navigation aid systems coexist and develop independently, making them difficult to be compatible with each other; These contents have increased the burden of ship driving, reduced the enthusiasm of mariners to use these systems and the effect of the system. [0003] In view of the above problems, an integrated bridge system for ship...
