Alarm system for intelligently detecting entering of ship into bridge pier safety protection area

Abstract

The invention discloses an alarm system for intelligently detecting the entering of a ship into a bridge pier safety protection area, and the system comprises a ship detection sensor, a signal processing circuit, a central processor and an alarm, wherein the ship detection sensor is disposed on a bearing surface of a bridge pier and faces the water surface, and the ship detection sensor, the signal processing circuit, the central processor and the alarm are sequentially connected. The ship detection sensor is a big-power supersonic sensor, and comprises a transmitting unit and a receiving unit. The signal processing circuit comprises a transmitting control unit connected with the transmitting unit, and a signal extraction unit connected with the receiving unit. The transmitting control unit and the signal extraction unit are respectively connected with the central processor. The central processor is connected with the alarm through a detection signal output control unit. The system achieves the real-time detection of the ship entering into the bridge pier safety protection area, and timely gives an alarm to a bridge management department.

Description

technical field

[0001] The invention relates to the field of bridge pier safety protection, in particular to an intelligent detection ship entry alarm system in a bridge pier safety protection area. Background technique

[0002] The piers of the bridges erected on the Yangtze River, the Yellow River and other rivers are easily collided by ships driving in violation of regulations. When the bridge pier collided and the ship owner escaped with the boat, the bridge management department failed to detect the collision in time, and could not conduct a safety assessment of the collided pier in time, causing the bridge to operate with hidden dangers, which was very dangerous. In order to ensure the safety of the bridge, ships are prohibited from entering the protection area around the pier (the size of the protection area depends on the nature of the bridge) (the ship is very likely to collide when entering the protection area, which is regarded as a safety hazard ) to avoid colli...
