Description

Unmanned aerial vehicle shouting switching system

Technical Field

The utility model relates to an audio frequency switches technical field, concretely relates to unmanned aerial vehicle shouts switched systems.

Background

With the continuous and deep research on unmanned aerial vehicles in China, the application range of the unmanned aerial vehicles is increasingly expanded, and the functions of the unmanned aerial vehicles are also increasingly powerful, so that the unmanned aerial vehicles have relevant applications such as military striking, monitoring, communication, surveying and mapping, disaster relief and the like.

Unmanned aerial vehicle and extend task load equipment etc. and have functions such as voice broadcast greatly, but this kind of equipment that has now does not possess the function of environment sound collection because voice broadcast's sound can influence the collection of environment sound.

SUMMERY OF THE UTILITY MODEL

The utility model provides an unmanned aerial vehicle shouts switched systems to solve among the prior art problem that the unmanned aerial vehicle product did not possess the function is collected to environmental sound.

In order to achieve the above object, the present invention provides the following technical solutions:

the utility model provides an unmanned aerial vehicle shouting switching system, including aerial execution end and ground control end through wireless signal communication, aerial execution end is including shouting switching module and wireless audio receiving module that set up on unmanned aerial vehicle, wireless audio receiving module connects shouting switching module, shouting switching module connects adapter and speaker; the wireless audio receiving module is used for receiving wireless audio signals sent by the ground control end and transmitting the wireless audio signals to the shouting switching module, so that the microphone works to switch the loudspeaker to work under the default condition through the shouting switching module.

As an optimized scheme of the utility model, the ground control end with wireless audio receiving module is two parts of talkbacking of intercom respectively.

As an optimized scheme of the utility model, shout switches module and includes that high level triggers analog switch and low level triggers analog switch.

As an optimized scheme of the utility model, the adapter triggers for the low level, just shout switches and is in the low level state under the module acquiescence, the speaker triggers for the high level.

As an optimized scheme of the utility model, the sound of speaker broadcast is the input the sound signal of intercom.

The utility model has the advantages of as follows:

after unmanned aerial vehicle's wireless audio frequency receiving module received the wireless audio signal that ground control end sent, it triggers to change into the high level by acquiescent low level through shouting the switching module and triggers, then close the adapter that triggers by the low level, open the speaker that triggers by the high level, the self-closing of adapter when realizing voice broadcast, and the low level that truns into acquiescent state after the speaker is reported triggers, the adapter continues work, therefore, realized the purpose as unmanned aerial vehicle's expansion module with the adapter.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below. It should be apparent that the drawings in the following description are merely exemplary, and that other embodiments can be derived from the drawings provided by those of ordinary skill in the art without inventive effort.

Fig. 1 is a schematic block diagram of a switching system provided by the present invention;

fig. 2 is a circuit diagram of a wireless audio receiving module according to an embodiment of the present invention.

Fig. 3 is a circuit diagram of the shouting switching module provided by the embodiment of the present invention.

Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, the utility model provides an unmanned aerial vehicle shouting switching system, including aerial execution end and the ground control end through wireless signal communication, aerial execution end is including shouting switching module and the wireless audio frequency receiving module of setting on unmanned aerial vehicle, the wireless audio frequency receiving module is connected the shouting switching module, shouting switching module connects adapter and speaker; the wireless audio receiving module is used for receiving wireless audio signals sent by the ground control end and transmitting the wireless audio signals to the shouting switching module, so that the microphone works to switch the loudspeaker to work under the default condition through the shouting switching module.

The ground control end and the wireless audio receiving module are two talkback parts of an interphone respectively and are used for sending wireless audio signals to the air execution end, and sound played by a loudspeaker is a sound signal input into the interphone; the shouting switching module comprises a high level trigger analog switch and a low level trigger analog switch, the sound pick-up is triggered by low level, the shouting switching module is in a low level state under the default condition, and the loudspeaker is triggered by high level.

As shown in fig. 2, the module 1 is a part of an intercom, that is, a wireless audio receiving module, and is configured to receive an audio signal sent from the ground, and the module 2 is a power amplifying module and is configured to amplify the audio signal.

As shown in fig. 3, the shouting switching module is mainly switched by the relay G6K, and after obtaining a high level generated after the wireless audio receiving module receives the audio signal, the relay G6K switches the output object and switches the sound pickup to the speaker.

The practical realization principle of the shouting switching system provided by the embodiment is as follows:

after wireless communication between a ground control end and an aerial execution end of the unmanned aerial vehicle is established; under the default condition, the unmanned aerial vehicle collects sound information of the surrounding environment through a sound pickup and stores the sound information; when the ground control end sends a wireless audio signal, the wireless audio receiving module of the aerial execution end receives the wireless audio signal and sends a high-level signal to the shouting switching module, and the shouting switching module closes the sound pick-up channel and opens the loudspeaker channel after receiving the high-level signal.

Wherein, the sound pick-up and the loudspeaker are two units which are independently arranged. The sound pick-up serves as a receiving unit (collecting unit) and the loudspeaker serves as an output unit, and the modes which are not operated simultaneously are set to avoid interference between the two units.

After unmanned aerial vehicle's wireless audio frequency receiving module received the wireless audio signal that ground control end sent, triggered by the low level of acquiescence through shouting the switching module and changes into the high level and trigger, then closes the adapter that triggers by the low level, opens the speaker that triggers by the high level, the self-closing of adapter when realizing voice broadcast, and the low level that truns into the default state after speaker broadcast triggers, and the adapter continues work.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
