Abstract

The invention relates to a ship-borne positioning device, and belongs to the field of ship electronic technologies. An upper cover is installed at an end part of a main board, a circuit board with an emission unit is installed at end parts of bosses of the upper cover, and L-shaped metal substrates are installed on side walls of the bosses; a piezoelectric vibrator is formed by a main beam of the metal substrate and piezoelectric wafers spliced with the main beam, and a first exciter is formed by a secondary beam of the metal substrate, and a first mass block and a first magnet which are installed on the secondary beam; four sink troughs are symmetrically arranged at the upper end of a main body, and a cavity is arranged at the lower end of the main body; limit surfaces are arranged on side walls between each two adjacent sink troughs, a swing rod is welded with the center of the bottom wall of the main body, a second exciter is formed by the swing rod, and a first spring, a second mass block with a second magnet, a second spring, a third mass block, and a third spring which are sequentially sleeved on the swing rod from the top down, and like magnetic poles of the first and second magnets are installed close to each other; a coil is installed on the bottom wall of the main body, and the coil is placed below the first or second magnet. The ship-borne positioning devices has the advantages and characteristics of being strong in environmental adaptability, wide in effective band and large in capacity density, being capable of serving as an independent component to be embedded into a secret place of a ship body, and being safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of ship electronic applications, and in particular relates to a ship-mounted positioning device. Background technique [0002] The ship positioning and tracking system has been widely used on civil ships, providing a strong guarantee for the ship's navigation safety, timely rescue, and search after losing contact. However, the existing positioning and tracking systems are all based on engine power supply. Once an accident occurs on the ship and the engine and the entire power system fail, the positioning and tracking system will lose its proper function. In addition, the existing positioning and tracking systems are all external, and cannot work normally when the ship is wrecked and flooded, and the positioning system is easily shut down or destroyed after the ship is hijacked by criminals. Therefore, in order to ensure the safe and reliable operation of the ship positioning system, it is necessary to have ...
