Screen advertisement is replaced.
However, there is some drawbacks as follows for existing electronical display advertisement machine:
(1) as the content viewing of advertisement broadcasting can not select；
(2) key and remote controller operation, advertisement machine are typically all to be placed in relatively high position, and button operation is inconvenient；
(3) remote controler can be compared with remote-controlled operation, but remote controler is a lesser monomer, is easily lost.
Utility model content
The purpose of this utility model is to provide a kind of advertisement motherboard voice activated controls to solve in above-mentioned background technique
The problem of proposition.
To achieve the above object, the utility model provides the following technical solutions: a kind of advertisement motherboard voice activated control, packet
The power management module for whole system power supply is included, for acquiring voice instruction and ambient sound and being converted to analog signal
Microphone module, for analog signal to be converted to audio A/D conversion module of digital signal, for digital signal to be converted to
The audio D/A converter of analog signal, for the system processing module of all data processings of whole system, for responsible and wide area
The WIFI module of net and LAN connection, for playing the loudspeaker module of ad sound and for the aobvious of presenting advertising content
Display screen module, the system processing module include CPU processing module and cloud service module, and the audio A/D conversion module will
The digital audio of conversion is transferred in CPU processing module by I2S, the CPU processing module by voice instruct and environmental noise
It is pushed in cloud service module after separation and by WIFI module networking by voice instruction, the cloud service module instructs voice
Executing instruction for generating after matching again with the voice instructions match in its database is sent back at CPU by WIFI module networking
It manages in module, and the voice after parsing execution is instructed and is transferred in display panel module by LVDS interface by CPU processing module, institute
It states after audio D/A converter amplifies the analog signal that digital signal is converted to by audio-frequency amplifier and is transferred to loudspeaker module
In.
Preferably, the power management module is made of adapter and a PMIC integrated circuit.
Preferably, the microphone module includes that the matrix of 4 artificial capacitor microphone compositions is constituted.
Preferably, the audio A/D conversion module supports the ADC chip and a sound of 4 tunnel analog audio inputs by two
Frequency power amplifier chips are constituted.
Preferably, the CPU processing module is by 4 core A53 processor, 1 LPDDR3, an EMMC storage chip
And crystal oscillator is constituted.
Compared with prior art, the utility model has the beneficial effects that a kind of advertisement machine sound provided by the utility model
Control system be by acoustic control can switching over to the ad content in advertisement machine, select oneself to like wide for audience
Accuse content, with it is existing with the advertisement machine of remote controler compared with, the use of remote controler is eliminated, so as to avoid losing for remote controler
It loses, it is very easy to use.
Detailed description of the invention
Fig. 1 is the working principle diagram of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, a kind of embodiment provided by the utility model is as follows: a kind of advertisement motherboard acoustic control system
System, including the power management module powered for whole system, for acquiring voice instruction and ambient sound and being converted to simulation
The microphone module of signal is used for for analog signal to be converted to audio A/D conversion module of digital signal by digital signal
It is converted to the audio D/A converter of analog signal, for the system processing module of all data processings of whole system, for being responsible for
With the WIFI module of wide area network and LAN connection, for playing the loudspeaker module of ad sound and for showing in advertisement
The display panel module of appearance, the power management module are made of adapter and a PMIC integrated circuit, the microphone mould
Block includes that the matrix of 4 artificial capacitor microphone compositions is constituted, and the system processing module includes CPU processing module and cloud clothes
Business module, the CPU processing module is by a 4 core A53 processors, 1 LPDDR3, an EMMC storage chip and crystal
Oscillator is constituted, and the digital audio of conversion is transferred in CPU processing module by the audio A/D conversion module by I2S, described
Audio A/D conversion module supports the ADC chip of 4 tunnel analog audio inputs and an audio frequency power amplifier chip to constitute by two, described
