Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to the field of training of animals, particularly marine mammals. The device for educating or training of water, marine animals comprises a sensor element and an indicator (4, 5, 6). The sensor element is made in the form of sealed ultrasonic sensor. The sensor consists of emitting (2) and receiving (3) elements.

EFFECT: ability to control the animal's approach to the target without touching it, the definition of the animal's preferences in selection of signals, and its ability to differentiate the movements accurately.

Description

The present invention relates to devices for training animals, in particular marine mammals and other marine life.

It is known to use a pointer with a target at the end (the so-called "target"), which the animal must touch. On the other hand, various levers and pedals are known, the force from pressing the pedal is transmitted mechanically to turn on various signal indicators: ringing the bell (1), raising the flag, etc. (2, 3).

The disadvantage of such systems is that the animal must be in mechanical contact with the signaling device. Not always the animal can accurately touch the pedal.

The aim of the present invention is the ability to control the proximity of the animal to the target without touching it, to control the dynamics and degree of approximation of the animal to the target, to determine the preferences of the animal in the selection of signals, as well as its ability to fine differentiate movements.

This goal is achieved in that the target at the end of the target is made in the form of a sealed ultrasonic sensor, consisting of a radiating and receiving elements.

Possibility of implementation

The drawing shows the design of the target sensor and the communication circuit of the sensor with signaling devices.

The sensor consists of an electronic unit 1, including a generator of high-frequency oscillations, for example 4 MHz, which is connected via a cable to the radiating piezoceramic plate of the sensor 2. The receiving piezoceramic plate 3 is located at a certain angle to the radiating one. The signal from the receiving plate through the cable goes to the electronic unit, where it is amplified and further commutated with the signal device. As a signal device, a light signal source 4, an underwater speaker (speaker) 5 or an acoustic speaker 6 can be used.

When the animal approaches the target sensor, which is below the water level and generates high-frequency ultrasonic vibrations, the reflected signal from the animal’s body, for example, rostrum 7, is received, which is received by the receiving plate, amplified and then fed to the signal device as a Doppler sound frequency. When approaching and moving away from the target sensor or swaying the rostrum in front of it, the animal can create sounds of various modalities, heard both in air and under water.
