Abstract
The utility model discloses a kind of automatic frequency aligning U sections of wireless microphones, including main control chip, the main control chip is bi-directionally connected with bluetooth, UHF transmitting key and display screen respectively, UHF transmitting, which is also sampled with microphone, to be connected, the main control chip is also connect with indicator light, the bluetooth is bi-directionally connected with U sections of wireless transmitters, and it further includes battery and charge management module that the UHF transmitting, which is unidirectionally connected to U sections of wireless transmitters,.U sections of wireless microphones of the automatic frequency aligning realize U sections of wireless microphone automatic frequency alignings by bluetooth data transmission mode, while carrying out frequency error factor automatically, prevent co-channel interference.
Description
Technical field
The utility model belongs to microphone to frequency technical field, and in particular to a kind of automatic frequency aligning U sections of wireless microphones.
Background technique
Wireless microphone, if being by the pocket transmitter of cadre (can be in pocket, output power about 0.01W) and a concentration
Receiver composition, every pocket transmitter have a mutually different working frequency, concentrate receiver that can receive simultaneously respectively
The voice signal for the different operating frequency that the pocket transmitter in portion issues.It is adapted to the occasions such as stage dais.
Current wireless microphone does not have the function of automatic frequency aligning, and is easy the interference by miscellaneous frequency, inconvenient to use.
A kind of automatic frequency aligning U sections of wireless microphones are proposed thus.
Utility model content
The purpose of this utility model is to provide a kind of automatic frequency aligning U sections of wireless microphones, to solve above-mentioned background technique
The problem of middle proposition.
To achieve the above object, the utility model provides the following technical solutions: a kind of automatic frequency aligning U sections of wireless microphones,
Including main control chip, the main control chip is bi-directionally connected with bluetooth, UHF transmitting key and display screen respectively, and UHF transmitting is gone back and miaow
Head sampling connection, the main control chip are also connect with indicator light.
Preferably, the bluetooth is bi-directionally connected with U sections of wireless transmitters.
Preferably, the UHF transmitting is unidirectionally connected to U sections of wireless transmitters.
It preferably, further include battery and charge management module.
The technical effect and advantage of the utility model: U sections of wireless microphones of the automatic frequency aligning, by bluetooth data transmission side
Formula realizes U sections of wireless microphone automatic frequency alignings, while carrying out frequency error factor automatically, prevents co-channel interference.
Detailed description of the invention
Fig. 1 is the system block diagram of the utility model；
Fig. 2 is the work flow 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.
The utility model provides a kind of automatic frequency aligning U sections of wireless microphones as shown in Figure 1, including main control chip, institute
It states main control chip to be bi-directionally connected with bluetooth, UHF transmitting key and display screen respectively, UHF transmitting, which is also sampled with microphone, to be connected, described
Main control chip is also connect with indicator light, and the bluetooth is bi-directionally connected with U sections of wireless transmitters, and the UHF transmitting is unidirectionally connected to U
Section wireless transmitter.
The device further includes battery and charge management module.
Start as shown in Fig. 2, clicking, first initialization UHF and bluetooth, then Bluetooth transmission request is to frequency signal, judgement
Whether return correctly to frequency signal, if it is return is configured parameter to UHF module to frequency signal by main control chip,
It completes to frequency, if not then backing within Bluetooth transmission to frequency signal, while after main control chip completion is to frequency, judgement is
It is no to there is key to grab current UHF by force, Bluetooth transmission request is if it is returned to frequency signal, and no then automatic frequency aligning terminates.
Working principle: built Bluetooth module and wireless microphone module on receiving host and U sections of wireless transmitters pass through
U sections of bluetooth sending and receiving corresponding frequencies and address information, so that the U root module for controlling and receiving host automatically switches to U sections of wireless hairs
Emitter (including but do not limit wear wireless transmitter, waist hangs transmitter, handheld microphone etc.) corresponding frequency and address, in turn
It is automatically performed the process of corresponding wireless automatic frequency aligning, and the wireless microphone of receiving host is automatic in not connected upper transmitting
Interfering frequency is scanned, when the bluetooth module of transmitting is shaken hands with received bluetooth module, receiving end notice transmitting terminal evades interference
Frequency avoid co-channel interference to realize automatic frequency-hopping.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
