Description

Navigation system with external base control and self-guided beacon.

Technical field

Marinas, navigable areas, surveillance and port security, sea rescue and transportation of small goods

State of the art

Next, we pass a quick vision at various possibilities of using the navigation system with external control base and self-guided beacon and the state is analyzed of the technique of each one of them.

Sport ports

The state of the art analysis concludes that currently there is no suitable solution to solve the main problem that a passerby encounters when arriving at a little known port, to locate the berth that has been assigned by captaincy (for example through communication radio). Especially in marinas with high offers of mooring and high traffic of passing ships (sports, sailboats, motorboats and canoes cars ...) which in some ports are immense, the user (navigator) of passage, completely ignores the distribution of said port, and in search of mooring designated, by default can cause traffic congestion Maritime and accidents.

Currently, this operation of locating the docking site, in some ports it is done manually, indicating to the boats their place of mooring by means of the help of a operator waiting in that place. The inconvenience of this solution is among others the need to hire staff what increases maintenance costs.

It is known that some boats have of an apparatus called "plotter", which points to them in screen the possible route to take. This solution either It succeeds for technical and economic reasons.

Navigable areas

Currently navigation in zones navigable as for example in all types of navigable channels, bays, lakes, rivers, etc., is done with the help of letters nautical. The drawback of these letters is the need to have to update them periodically to reflect possible changes in depth, new obstacles, etc.

Port Surveillance and Security

Port surveillance, today, requires an operator in charge of performing said operations. This type of Surveillance is unreliable, uncomfortable, hard and dangerous.

Sea rescue

The maritime rescue device present in most of the coasts (especially Spanish) it is composed of a base port to cover a large area of territory. The drawback is among others the response time Very excessive in certain emergencies. It also endangers the life of the crew and the ship itself in some performances.

Small goods transport

Currently the transport of small merchandise, courier and mail service in those areas where there is a large group of islands (for example Islands Balearic Islands), is carried out using manned vessels. This type of transport demands increase in the number of ships, labor (crew), and consequently cost increase, expenses of fuel etc.

The navigation system with external base of self-guided control and beacon allows to avoid these inconveniences and precisely eliminate manned vessels, decrease the fuel consumption, improve the environment, etc.

Brief description of the present invention patent

The present invention patent, as expressed in the statement of this specification, refers to a navigation system with external control and beacon base self-guided representing a completely new solution. its movement is controlled from an external base unit of control.

The main objective of this Patent of Invention is to provide a guided floating artifact, that is a self-guided beacon to facilitate:

All this through a specific software.

Operation of the navigation system with external base of self-guided control and beacon

The different tasks to be performed by the navigation system have very different characteristics and they force to modify certain conformations in each case, according to the specific needs, although the basic scheme of operation It remains the same.

In any application for which it is used, the navigation system will be able to trace a trajectory defined by the user from an external control base equipped with specific software and a communications base that connects a location system (for example, GPS, GALILEO technology, etc.), positioning and monitoring with a pilot system Automatic boat and can correct possible deviations caused by sea currents, wind, etc.

Example of an embodiment of the invention

For a correct interpretation, a then a case of practical realization, by way of example, not limited, of the present Invention Patent, accompanied by the drawings Figure 1 (Schematic drawing of the self-guided beacon), Figure 2 (Rear view of the self-guided beacon), Figure 3 (View side of the self-guided beacon), Figure 4 (Example of operation), with which you can clearly justify your feasibility of manufacturing and application.

The navigation system with external base of self-guided control and beacon, described below as an example, It is intended to guide incoming vessels in a port, until its mooring.

Detailed description of the invention

As shown in figure 1, this beacon It would have the following main characteristics:

- Length: 1.52 m.

- Width: 1.05 m.

- Total Height: 2.03 m.

- Height from water plane: 1.90 m.

As can be seen in figure 1, the beacon It consists of a small door (1) for maintenance and repair electric

The base of the beacon is provided with some pins (2) to facilitate engine repairs, since this It will be housed inside and at the water level.

A ring (3) surrounds the beacon protection and at the same time help the operator to be able to take it out and put it afloat, either manually or mechanically, depending on the scale of it.

At the top you can distinguish the communication antenna (4) with a light pilot (5).

The beacon will be provided with an autopilot (8) housed inside, with hydraulic steering (6), a possible video camera (9) and placement area of first aid kit (10), as well as two floats (7) that guarantee its buoyancy and navigability.

Next, in Figure 2, it is shown to This example the rear view, where you can observe:

- The propeller (14)

- The helm (13)

- Hydraulic steering (6)

- Pins (2)

- Engine (11)

- Floats (7)

- Batteries (12)

It is also shown in Figure 3 (removing one of the floats), the arrangement of the rudder (13), provision of the propeller (14), arrangement where the motor is housed (11) and the batteries (12), hydraulic steering arrangement (6) and float (7).

The engine in this example should ensure a speed equal to or less than 3 knots inside port enclosures to overcome possible currents against, since the legislation of ports prohibits a speed greater than 3 knots within said enclosure.

Once the appropriate beacon has been described Below is a graph of how to use or operation of it.

It should be clarified that previously the enclosure port must be fully "parameterized" that is through multiple input-output waypoints in one  GPS that together with the software would be installed in the base external control

So each mooring number would have a number determined of waypoints of entry plus ones of exit, which would be transmitted to the beacon by communication external control beacon base. The beacon upon receipt the waypoints of said external control base, will put in engine and autopilot operation, which should be set towards these entry points, and go checking and completing one by one until reaching the last one, which would indicate the place of tie up

It cannot be said that the closer find the waypoints of each other, the smaller the deviation of the beacon

Once the berth of the The beacon must return to its place of origin, with the exit / return waypoints supplied by the base, without any trouble.

In Figure 4, a possible example of entry and exit of the beacon before the entry of a ship to port, where the black dots would be the entry waypoints until the mooring (numbered from 1 to 15), and marked on white-black would be the waypoints of exit until the base (numbered 16 to 30).

It is possible to say that the locations of the Waypoints would be multiple, depending on the possible entries and outputs depending on wind direction, congestion traffic, weather conditions, etc. being able to combine all in a simple / special input and simple / special output, etc.

Finally, it is not considered necessary to do more extend this description so that any subject matter expert understand the scope of the invention and the advantages thereof They derive. It is also understood that how many variables will be finishing and construction details do not alter, change or modify The essentiality of the invention.

The object of the Invention Patent, which is declared as new and of its own invention.
