ES2239493B1 - CONTROL AND SURVEILLANCE SYSTEM OF UNDERWATER ARCHAEOLOGICAL REMAINS AND WATER QUALITY. - Google Patents

Abstract

System for the control and surveillance of underwater archaeological remains and water quality, is a device composed of an underwater hydrophone (1) for detecting signals (A) integrated in a floating and watertight element (2) inside which are sensors and electronics. The hydrophone and the sensors provide predetermined data, which is transmitted by BLUETOOTH technology (B) to the reception center, which determines the alert on the presence of intruders (objects or people) or the state of contamination of the waters on the PECIO ( 3) or archaeological remains. The applications of the system solve the existing problem on the surveillance and control of the remains, instantly alerting of possible looters or intruders on them. At the same time, the analysis of the waters warns of possible pollutants that can harm the remains and the aquatic environment. It is a useful alternative for pollution alarm on beaches, ports, reservoirs, fish farms, rivers, etc. The self-protection system procedure makes it work flush with the water (4) or anchored to the bottom (5). From the bottom, the system acts in the same way of surveillance and in turn specifies the volume and thickness of a contaminating mass or foreign body on the surface, as well as its direction. The system can be automatically released from the wire (6) attached to the anchor (7) and be controlled by remote control, thus fulfilling a function of pursuing the intruder, be it an object or a contaminant.

Description

Control and surveillance system of remains underwater archaeological and water quality.

The invention falls within the technical sector of processes for the control and surveillance of remains underwater archaeological sites and the environment in which they are found: seas and rivers. Conjugating the determinants of different databases: acoustic, biological, informatics, communications and analytics.

The protection and dissemination of underwater archaeological remains is currently necessary and mandatory. UNESCO establishes this, but it is currently very difficult to meet the requirements of protection and public approach to them and, with the control and surveillance system, the proposed objectives are achieved. It watches to avoid theft, it watches over so that its visualization, in situ , is adequate, safe and not harmful.

In turn, monitor and control the state of the waters surrounding the wreck, which represents a remarkable technical advance that carries out the surveillance, control and security of the remains and people since the system gives us the necessary information on the state of the waters, their visibility, the currents, their quality.

The invention provides the solution to problems raised by the occupation of bulky appliances, which deteriorate the landscape and the environment near the coast where they combine the influx of bathers with sports activities, nautical, diving or fishing.

Due to its size it is very useful to be integrated in surveillance and control uses in ports and especially in its marshes where the spills of substances contaminants is difficult to control. A device placed in a Pantanal would detect in milliseconds the contamination of the Water. A device placed at the exit of an industry that pour into the river or sea would detect in the same way if the water spills contains substances that may endanger the health of the waters. Thus avoiding irreversible ecological tragedies.

The system monitors strange agents located on the archaeological remains: ships, people and agents pollutants, alerting the control post by alarm corresponding, which will have the capacity to register, control and management of alarm incidents.

The system is a floating and watertight element with sensors and electronics inside that is located in the center of the supervisory area. With energy subsystem.

Intrusion detection is carried out by aquatic hydrographer and pollutants with specific and determined microsensors for the different analysis.

The data transmission will be carried out with BLUETOOTH technology that allows reception in thousandths of seconds the alarm of intruders or pollutants.

Its reversible data collection system in the water surface and underwater bottom allows other non-existent applications. Theft is prevented in the first place, deterioration or accidental rupture providing it with an intelligent system of self-protection. His performance from the bottom underwater would be highly useful for detecting agent stains and thicknesses strange and harmful to the aquatic environment as well as the address of the same. For example an oil slick today today it can be viewed via satellite when it has already appeared and also your address. The new system would immediately detect the crude oil output in thousandths of seconds and the internal current e external of the waters.

Automatic release of the anchor system and its management by remote or robotic control makes the system have your application for maintenance moving on site tidy and also be very useful to chase the stranger, be this object or contaminating material.

Description of figure 1

The wreckage control and surveillance system archaeological and water quality is composed of an antenna underwater (1) that receives information from the hydrophone about the which is situated (2).

Hydrophone goes through power device or battery (3) and the device box (4) appearing after its bottom in the same higher proportion.

The device box contains a grid of water passage (5) for communication with internal sensors for its analysis.

Joins the bottom anchor (9), next to the wreck to be protected (8), by means of a high resistance wire (6) which contains a sensor (7).
