Abstract
The utility model discloses a novel broadcast device, including bluetooth audio receiver, main control unit, audio frequency drive circuit, human infrared monitoring module, relay, supply socket. The utility model discloses an infrared detection technology can judge whether the user is using the broadcast device, when the user in the application range of broadcast device, when the broadcast device but was in normal operating conditions, main control unit will control relay operation, the power of automatic cutout broadcast device to practice thrift the zero loss of electric energy, realization electric energy. When the surrounding environment was dark, the smooth signal transmission that photo sensor will detect gave main control unit, and main control unit control light source drive circuit drive LED lamp throws light on, and it is more convenient to use.
Description
Technical field
This utility model relates to radio and television equipment technical field, particularly relates to a kind of novel public address system.
Background technology
Along with improving constantly of people's living standard, increasingly abundanter literature and art life, people also increasingly concern stereo set sing and speech problem, the tonequality of public address system and the appreciation level of effect is more and more higher.Public address system is the peripheral unit being widely used in multi-media player in recent years, its principle transmits signal mainly by the electric connection between public address system and multi-media player, thus, in order to reach to play the purpose of multimedia audio, it is provided that preferably ease of use.
But, existing public address system cannot judge whether user is currently in use public address system, when user leaves or forgets to close public address system power supply, will result in the wasting of resources, wastes substantial amounts of electric energy.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, designs a kind of novel public address system.
For reaching above-mentioned purpose, this utility model be the technical scheme is that
A kind of novel public address system, including the audio signal transmission that will receive to the Bluetooth audio receiver of master controller, master controller, this public address system of audio-signal-driven transmitted according to described master controller carries out the audio drive circuitry broadcast, also include for detecting the human body infrared monitoring modular whether user is currently in use, control signal according to master controller is cut off the electricity supply the relay of socket, supply socket, the described signal output part of human body infrared monitoring modular is connected with the signal input part of master controller, the signal output part of master controller is connected with the controlled end of relay, relay is connected with supply socket.
Further, also include for gathering surrounding luminance signal and luminance signal being transferred to the optical inductor of master controller, the light source driving circuit driving according to the control signal of master controller LED to be illuminated, LED.
Further, described master controller adopts STM32F103 single-chip microcomputer.
Further, described human body infrared monitoring modular adopts DYP-ME003 pyroelectric sensor.
Positive beneficial effect of the present utility model:
1, by infrared detection technique, this utility model can interpolate that whether user is currently in use public address system, when user is not within the scope of the use of public address system, when public address system is but in normal operating conditions, master controller will control the actuating of relay, automatically cut off the power supply of public address system, thus saves energy, realizing zero loss of electric energy.
2, when surrounding is dark, optical inductor is by the optical signal transmission that detects to master controller, and main controller controls light source driving circuit drives LED to be illuminated, and uses more convenient.
Accompanying drawing explanation
Fig. 1 is one of theory structure block diagram of the present utility model.
Fig. 2 is the two of theory structure block diagram of the present utility model.
Detailed description of the invention
Detailed description of the invention of the present utility model is illustrated below in conjunction with accompanying drawing.
Embodiment one, referring to Fig. 1, novel public address system of the present utility model, including the audio signal transmission that will receive to the Bluetooth audio receiver of master controller, master controller, this public address system of audio-signal-driven transmitted according to described master controller carries out the audio drive circuitry broadcast, also include for detecting the human body infrared monitoring modular whether user is currently in use, control signal according to master controller is cut off the electricity supply the relay of socket, supply socket, the described signal output part of human body infrared monitoring modular is connected with the signal input part of master controller, the signal output part of master controller is connected with the controlled end of relay, relay is connected with supply socket.
Described master controller adopts STM32F103 single-chip microcomputer.
Described human body infrared monitoring modular adopts DYP-ME003 pyroelectric sensor.
By human body infrared monitoring modular, this utility model can interpolate that whether user is currently in use public address system, when user is not within the scope of the use of public address system, when public address system is but in normal operating conditions, master controller will control the actuating of relay, automatically cut off the power supply of public address system, thus saves energy, realizing zero loss of electric energy.
Embodiment two, referring to Fig. 2, the present embodiment and embodiment one are different in that, also include for gathering surrounding luminance signal and luminance signal being transferred to the optical inductor of master controller, the light source driving circuit driving according to the control signal of master controller LED to be illuminated, LED, when surrounding is dark, optical inductor by the optical signal transmission that detects to master controller, main controller controls light source driving circuit drives LED to be illuminated, use more convenient, other detailed description of the invention are identical with embodiment one, specifically repeat no more.
Finally should be noted that: above example is only in order to illustrate that the technical solution of the utility model is not intended to limit；Although this utility model being described in detail with reference to preferred embodiment, those of ordinary skill in the field are to be understood that；Still detailed description of the invention of the present utility model can be modified or portion of techniques feature is carried out equivalent replacement；Without deviating from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that this utility model is claimed.
