Abstract

The sonar network has three parts, which are connected with each other by data cables. The former part consists of a computer and an interface box. The later part is a sound box network arranged in machine room and the third part includes transducers. The computer sends a sound request to sound box through network interface box. An ultrasonic signal is provided by transducers to the interior of the network. The sonar network box receives a response from the transducers and sends a message, back to the computer by the interface box.

Description

Network sound

Object of the invention

The present invention relates to a sonar of net, specifically for nets used in purse seine fishing in surface, which provides substantial novel features and Remarkable advantages compared to known media and used for the same purposes in the current state of the technique.

More particularly, the invention develops a system that provides information on the quantity and type of fish found inside the net, when the boat make a start, with very high resolution. The sectors in the This system can be used are: Tuna fishing vessels with object; Coastal vessels; Sardineros; and, in general, any boat that performs purse seine fishing.

Basically, the operation of the network Sonar Object of the invention is as follows. At any given time, from the computer that controls its operation makes a request of service to the Sonar, obtaining as a result an image, similar to some extent to a photograph, of the fish content in the inside the network.

Background and summary of the invention

It is known by everyone in general the fact that, in certain types of fishing, the use of some detection system that allows to know the content of the network used This is possible with the Probes, although these are not able to discriminate objects by size. In addition, the largest Efficiency of the Probes is achieved towards the bottom, when for the Surface fishing requires that the efficiency be lateral. By On the other hand there are also the Sonares. These provide information at a 360 degree angle, an unnecessary thing in the surface purse seine fishing, but that raises very Significant cost needed.

Taking into account the associated inconveniences to the systems currently used, the present invention It has been proposed as the main objective to provide a system through which effective solutions are provided to the raised problem, and by which the fact of avoiding having to face high costs for such an application concrete This objective has been fully achieved through the Network Sonar proposed by the invention, whose main features are included in the characterizing part of the attached claim 1.

In essence, the Sonar de Red proposed by the invention is likely to be mounted on a wafer in the boat hull, with lateral orientation and adapted to the route of the net in the start for fishing. It is able to discriminate 1 cm. at a distance of 1 km, making a true photograph of fish In addition, the application is fully automated, providing very accurate information on fishing in the inside the network. With all this, the end result is a product with an unbeatable relationship price quality.

Brief description of the drawings

This and other features and advantages of the invention, will become more clearly apparent from the detailed description that follows in a preferred way of embodiment, given by way of illustration only and not limiting, with reference to the accompanying drawings, in the that:

Figure 1 is a view showing a boat with the location of the boat (1) for transducers proposal.

Figure 2 is another view of the ship, in which the nozzle (1) is appreciated with the transducers (5), and the box network sonar (4).

And Figure 3 shows a scheme that summarizes the Network Sonar operation through the interaction of its various elements

Description of a preferred embodiment

As indicated above, the  detailed description of the invention will be carried out in what follows with the help of the attached drawings, through the which the same numerical references are used to designate the same or similar parts.

Thus, attending first to the representation of figure 1, a perspective of a boat with the nozzle (1) for the transducers welded to your helmet, specifically in its central part. This fact should not be understood as limiting in any way, since everything that it is said it is equally applicable in the case where the form of chosen realization be another.

Figure 2 shows another view of the ship, in which the nozzle (1) is appreciated with the transducers (5), and the network sonar box (4).

Centering the description in Figure 2, it You can see that it consists of three clearly differentiated parts. On the one hand, the computer (2) and the interface box (3); for another side, the network sonar box (4); and finally the boat (1), in which the transducers are located (5).

The computer (2) is located on the bridge of the boat, and from it the application is controlled and the results. The interface box (3) is installed so that it remains attached to the computer (2), and serves as a communication driver of the computer with the network sonar box (4), both for the Transmission as for reception.

The network sonar box (4) is located in the room of boat machines. It has connection with the interface box (3) using a data and power cable. At the same time, it has connection with transducers (5) placed on the wafer (1) by a power cable. This box consists of following elements:

one

source feeding (6);

2

control cards (7);

2

transducer trigger cards 8);

one

Data interface (9);

The operation process is the next:

Both the computer (2) and the sonar box mains (4) through the power supply (6) receive voltage from an AC outlet (10).

The nozzle (1) is installed welded on the part bottom of the ship's hull, and in it the transducers are located (5).

From the Computer (2) a request is made Sonar, which is collected, through the data interface (9), by the control cards (7). They process the signal, and decide which of the transducers (5) will be triggered. So the card corresponding control (7) sends a trigger signal to the trigger card (8) of the chosen transducer (5). The shot electrical sent by it becomes the transducer (5) in an ultrasonic signal, which travels into the network collecting information from the echoes created in the bodies with the found, which are reflected and picked up again by the transducer This signal is processed on the control card (7), and the result is sent through the data interface (9) to the computer (2), which is responsible for viewing it. This process is repeated continuously, allowing to obtain a photograph of the passage of fish within the network, and even save data from a start for later reproduction and study.

It is not considered necessary to make the content of this description for a subject matter expert can understand its scope and the advantages derived from the invention, as well as develop and implement the object of the same.

However, it should be understood that the invention has been described according to a preferred embodiment thereof, so which may be subject to change without implying any alteration of the basis of said invention, being able to affect such modifications to the shape, size and / or Manufacturing materials. These modifications could, in a future, assume the following extensions;

?

Increase in the number of side transducers to be placed on the boat, and display on the controller of the signals received by all of them at the same time, thus performing a simulation of the fish movement from different positions and angles. This will be necessary double the number of the different cards (7), (8), (9) of the network sonar box (4), and update the computer software (2).

?

Measuring the depth of the network while the long or extended network is taking place, in order to synchronize the descent of the network with the passage of fish inside it, thus optimizing the catch at prevent fish from escaping before closing the net. For it it will be necessary to update the computer software (2), as well as placement of depth sensors at the lower ends of the network, that will send information of the descent of this one. This information will be received by transducers (5) and interpreted by the computer (2).
