System and method of anti-collision low false warning rate height-limiting early warning for inland river bridge

Abstract

The invention relates to a system and method of anti-collision low false warning rate height-limiting early warning for inland river bridges, which comprise a transmitting end of the height-limiting early warning system and a receiving end of the height-limiting early warning system. The transmitting end of the height-limiting early warning system comprises a synchronous control unit transmittingend, a short-distance monitoring radar and a laser opposite-emitting transmitting end, wherein the short-distance monitoring radar and the laser opposite-emitting transmitting end are respectively incommunication connection with the synchronous control unit transmitting end. The receiving end of the height-limiting early warning system comprises a synchronous control unit transmitting end, a laser opposite-emitting receiving end and an acousto-optic alarm, wherein the laser opposite-emitting receiving end and the acousto-optic alarm are respectively in communication connection with the synchronous control unit transmitting end. According to the ship navigation information of the ships which are about to pass through the bridges along the waterway monitored by the monitoring radar in realtime, the laser opposite-emitting end and the laser opposite-emitting receiving end are started to form an opposite-emitting light path, and when the opposite-emitting light path is shielded, a ship superelevation early warning is sent out through the acousto-optic alarm. According to the anti-collision low false warning rate height-limiting early warning system and the method for inland river bridges, an early warning alert and a capture recording can be carried out on the ship exceeding the limited height of the bridge, thereby the accident that the ship collides with the bridge due to superelevation can be prevented, and the false alarm rate is low.

Description

technical field [0001] The invention relates to a height limit early warning system and method for inland river bridges, in particular to an anti-collision low false alarm rate height limit early warning system and method for inland river bridges, belonging to the technical field of safety early warning. Background technique [0002] Inland waterway transportation is an important part of the comprehensive transportation system and the comprehensive utilization of water resources. The large number of bridges in inland waterways has brought certain obstacles and restrictions to waterway transportation. At the same time, the vigorous development of inland waterway transportation has also brought severe challenges to the safety of bridges. . Therefore, it is of great value and significance to study the safety and collision avoidance of bridges in inland rivers. [0003] Ship-bridge collision accidents caused by superelevation of ships account for a high proportion of bridge saf...

However, even if the multi-line shooting scheme is adopted, false alarms will still be generated due to birds or floating objects in the air during actual use.
