Problems solved by technology

[0003] Large ship accommodation space and high requirements for safety lead to high cost of ships. In addition, due to the special environment of water surface transportation, repair and maintenance of ships are difficult and costly
Once a ship has an accident, such as a collision accident, not only the maintenance is time-consuming, but also brings great economic losses to the ship operator. Therefore, ship manufacturers have customized different safety alarm systems for the ship to call the police in time before a navigation crisis occurs.

Embodiment Construction

[0016] The embodiment of the step-by-step ship underwater distance warning device of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] During the sailing process of the ship, for the ship driver, the surface target is easy to find and avoid. On the contrary, the underwater target is far away from the line of sight, has high concealment, and the underwater situation is complex, and there are various targets that may appear , such as submarines, mines, schools of fish, sunken objects, landforms, etc., so the probability of collision is greater and the degree of danger is higher.

[0018] In order to fully understand the underwater situation under the ship, people use a variety of detection equipment to detect targets and restore landforms. These detection equipment include transducers, underwater ranging sensors and underwater cameras.

[0019] The so-called transducer is to emit sound waves to the bottom of the water, ...

Abstract

The invention relates to a graded progressive ship underwater distance alarm device. The alarm device comprises a threshold setting apparatus, a transducer and a control apparatus, wherein three water bottom distance thresholds are set by the threshold setting apparatus according to the descending order, the transducer measures and outputs the ship bottom target distance, the control apparatus is connected with the threshold setting apparatus and the transducer, and graded progressive ship underwater distance alarm can be achieved on the basis of the ship bottom target distance and the three water bottom distance thresholds. According to the graded progressive ship underwater distance alarm device, graded progressive alarm is carried out on the ship underwater distance, different alarm strategies are implemented according to specific ship underwater distance conditions, ship drivers are prevented from being excessively anxious while it is ensured that ships navigate safely, and the alarm effect on the ship underwater distance is effectively improved.

Description

technical field [0001] The invention relates to the field of underwater distance alarms, in particular to a hierarchical and progressive underwater distance alarm device for ships. Background technique [0002] Ships have irreplaceable advantages for water transportation. First of all, the ship has a large cargo capacity and low transportation cost. Secondly, the arrival time of the ship is relatively fixed, the voyage period is predictable, and the goods are transported on the water, which avoids frequent customs declarations between countries and saves the storage space of the goods. Dedicated warehouses. Therefore, even though the development of air and land transportation is fierce today, and the transportation speed and efficiency are higher than that of shipping, shipping still occupies a place in transportation. [0003] Large ship accommodation space and high requirements for safety lead to high cost of ships. In addition, due to the special environment of water su...
