Software-radio-based intelligent bridge system for ship

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...

Problems solved by technology

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 navigators to use these systems and the effect of the system

[0004] However, various navigation equipment, ship operation control equipment, and radar collision avoidance equipment in the ship's integrated bridge system are connected to the working machine as the display and control terminal through an external network. In the case of reducing the number of original various equipment on the bridge, the centralized display and centralized control achieved through simple integration of various equipment and higher-level comprehensive processing of bridge information have not reduced the number of various ships that the crew needs to master. the amount of bridge equipment, thus not reducing the burden on the ship's pilots
