Unattended bridge anti-collision early-warning device and method

Abstract

The invention discloses an unattended bridge anti-collision early-warning device and an unattended bridge anti-collision early-warning method. The unattended bridge anti-collision early-warning device comprises an AIS module, a radar water level sensor, a voice module, a VHF radio station, a power supply module, a wireless module and an information processing module. The unattended bridge anti-collision early-warning method comprises the steps of: installing a bridge anti-collision device in a navigation bridge opening or on an anti-collision pier of a bridge; setting an early-warning distance, wherein the early-warning distance can flexibly be set according to size of the bridge; acquiring and parsing AIS dynamic information and static information of all ships within the early-warning range; subjecting AIS English ship names to information processing for error correction, table look-up and translation, and translating the AIS English ship names into corresponding Chinese character ship names; and completing conversion of warning text information to audio information, and controlling the VHF radio station to transmit warning information. The method has the advantages of automatically completing the whole process, saving early-warning workload, overcoming the defects that traditional lamplight warning cannot function and even the VHF radio station requires excessive manual intervention in bad weather such as heavy rain and dense fog, and effectively reducing the risk of collision between a ship and the bridge.

Description

technical field [0001] The invention relates to the technical field of bridge active anti-collision protection, in particular to an unattended bridge anti-collision early warning device and method. Background technique [0002] With the rapid development of waterway traffic, the number of ships is increasing and the size of ships is increasing. The density of navigation in the bridge area is high, and the safety situation of navigation is extremely severe. Collision protection measures, the existing common means are: [0003] 1. Set up signs and navigation lights, and use LED warning signs, horn sound warnings and VHF radio cycle warnings. Although these methods are low in cost and simple, they cannot collect bridge water level information in real time. In severe weather such as heavy fog and rain When the vision is poor, it is easy to lose the protective effect. In addition, because the cab itself is noisy when the ship is sailing, the horn sound warning cannot transmit th...

Problems solved by technology

[0003] 1. Set up signs and navigation lights, and use LED warning signs, horn sound warnings and VHF radio cycle warnings. Although these methods are low in cost and simple, they cannot collect bridge water level information in real time. In severe weather such as heavy fog and rain When the vision is poor, it is easy to lose the protective effect. In addition, because the cab itself is noisy when the ship is sailing, the horn sound warning cannot transmit the alarm sound to the driver when the power is too small, and the power is too high, which will cause noise to the residents around the bridge. interference

Although the VHF radio can transmit the warning information to the driver, it cannot recognize the name of the ship and the movement of the ship, which will cause the driver to misunderstand. In addition, the loop playback will occupy more CH16 channels

[0004] 2. Use radar position-indicating signs to mark the navigable bridge hole, use VTS (Vessel Traffic Management System) to manually track and monitor ships 24 hours a day, and broadcast navigation warning prompts. This method cannot timely inform nearby navigation ships of the real-time water level information around the bridge, and Complex installation, high cost, frequent manual intervention, not feasible in the bridge area with heavy traffic
