The device of protected voice radio control by the functions of an unmanned aerial vehicle

The utility model belongs to the field of analysis, synthesis, recognition and protection of speech control commands in systems of protected voice radio control. The most commonly used utility model will have in various versions the implementation of the device of protected voice radio control by the functions of an unmanned aerial vehicle (UAV) in conditions when it is necessary to exclude the possibility of interception of UAV control by unauthorized persons.

General Characteristics, Concept of Development

The utility model is based on the task of creating a device for protected voice radio control of UAV functions.
The set task is solved by the fact that the device of protected voice radio control by the functions of a UAV consisting of a microphone, an analog-to-digital converter (ADC), a voice command analysis unit, a semantic parameters selection unit, a semantic parameters comparison unit, a control signal formation unit, a UAV actuator and built-in radio transmitter and radio receiver, according to the useful model, additionally included a semantic substitution unit parameters, authentication parameter selection unit, authentication parameter substitution unit, voice command counter, authentication parameter comparison unit, authentication parameter database, voice command synthesis unit, and a solving device that, based on the results of authentication, allows or prohibits the transfer of the generated control signal to the UAV actuator.

Comparison with World Analogues, the Main Advantages of Development

None of the known patents in question contains means of the same purpose that allows to obtain the necessary technical result, namely, well-known remote voice control devices based on recognition without taking into account the voice characteristics of the spoken commands, do not use the voice differences of the subjects of control, and therefore do not carry out voice authentication to determine the access rights of the control entity and do not implement protection against the possibility of interception radio control of the actuator of the control object.
The device of protected voice radio control by UAV functions presented in this utility model is implemented in such a way that during the recognition of voice commands of the control entity, not only semantic, but also authentication parameters of these commands are determined, followed by their substitution and synthesis of voice commands with the initial meaning but with the parameters of authentication of each subsequent command sent to the radio in a pseudo-random way, which provides protection against the possibility of interception of radio control by UAV functions by unauthorized persons throughout the control session.
