Embodiment Construction

[0019] Such as figure 1 and Figure 5 The AIS-based active collision avoidance system for the Jianghai Bridge shown includes a navigation information processing unit, a data processing unit, and a voice signal sending unit that can exchange data with ships and ship traffic management systems. The data processing unit communicates with navigation information processing units respectively. The unit and the voice signal sending unit can complete data exchange; the navigation information processing unit includes four ship automatic identification systems, which are evenly installed on two main navigation piers or; the data processing unit is a digital signal processor with an improved Harvard architecture The voice signal sending unit is a VHF wireless phone with automatic answering function, which can send the voice signal generated by the independent Chinese speech synthesis module to the ship and ship traffic management system.

[0020] The navigation information processing un...

Abstract

The invention discloses an AIS based river and sea bridge active anti-collision system. The system comprises a navigation information processing unit, a data processing unit and a voice signal sending unit which can form data exchange with ships and a ship traffic management system, wherein the data processing unit can finish data exchange with the navigation information processing unit and the voice signal sending unit. According to the technical scheme, the navigation information processing unit is used for sending navigation main pier information to the ships, receiving ship information and transmitting the ship information to the data processing unit; the data processing unit operates according to the received ship information, analyzes the states of the ships and judges whether a collision risk exists in the ships or not, if the collision risk exists, the data processing unit timely sends a voice alarm to the voice signal sending unit, and if the collision risk does not exist, the data processing unit timely sends a voice prompt to the voice signal sending unit.

Description

technical field [0001] The invention relates to a bridge engineering anti-collision technology, in particular to an AIS-based active anti-collision system for Jianghai Bridge. Background technique [0002] With the rapid development of the national economy and transportation, on the one hand, the construction of large bridges across rivers and seas can relieve traffic pressure and promote land transportation; on the other hand, the tonnage and number of transportation ships can be increased to improve water transportation capacity. For water transport ships, the bridge becomes an artificial obstacle. Accidents of bridges hit by ships happen frequently, and bridge collapses caused by them are increasing day by day. The Yangtze River Bridge and the sea-crossing bridge have become the main arteries of my country's land transportation, and the problem of ship collision with the bridge is particularly prominent. [0003] From the records of ship collision accidents at home and ...
