According to the anti-interference wireless doorbell of the utility model, through adopting two nRF24LE1 modules, namely, the nRF24LE1 emitting module and the nRF24LE1 receiving module, the wireless communication between the indoor unit and the outdoor unit can be realized; and the nRF24LE1 modules work in a 2.4-to-2.5GHZ ISM band, and there are as many as 125 frequency points, and therefore, interference can be avoided through changing frequencies, and the anti-interference wireless doorbell has extremely strong anti-interference ability.
Description
Technical field
The utility model belongs to the doorbell field, is specifically related to a kind of anti-interference wireless doorbell.
Background technology
Wireless doorbell claims wireless remote control doorbell or remote control doorbell again.Wireless doorbell is a class doorbell that utilizes civilian wireless technology (Zigbee, WIFI, bluetooth, 2.4G etc.) to develop.About 40 meters of general wireless doorbell effective propagation path.Adopt 2.4G frequency wireless transmission of video or voice signal in recent years, transmission range transmission range under barrier-free environment can reach 400 meters.Wireless doorbell does not need wiring, and simple and flexible is installed, and is bigger but transmission range is influenced by transmission range and site environment.
Along with social economy and science and technology development, the wireless device that uses in people's live and work is also more and more, and most of wireless device works in the 2.4GHZ frequency range, use the advantage person of being to use of this frequency range to need not licensing, easy to use and save cost, can avoid the interference of low-band signal and household electrical appliance simultaneously.But this frequency range has been converged the application of standard agreements such as bluetooth, Zigbee, WIFI, W-LAN, thereby its interference free performance is relatively poor.
The utility model content
The utility model provides a kind of anti-interference wireless doorbell at above-mentioned the deficiencies in the prior art; The interference free performance of this anti-interference wireless doorbell is better.
The utility model is achieved by the following technical solution:
A kind of anti-interference wireless doorbell comprises the off-premises station and the indoor set that link to each other with wireless mode; Described off-premises station comprises first primary processor, nRF24LE1 sending module and bell button module; The bell button module links to each other with first primary processor, and first primary processor links to each other with the nRF24LE1 sending module; Described indoor set comprises second primary processor, nRF24LE1 receiver module and audio-frequency module; The nRF24LE1 receiver module links to each other with second primary processor, and second primary processor links to each other with audio-frequency module; NRF24LE1 sending module and nRF24LE1 receiver module are by the wireless mode communication.
Further setting of the present utility model is that described audio-frequency module comprises recording submodule and playback submodule.
Further setting of the present utility model is that described off-premises station also comprises first microphone and first loudspeaker, and described first microphone all links to each other with first primary processor with first loudspeaker; Described indoor set also comprises second microphone and second loudspeaker, and described second microphone all links to each other with second primary processor with second loudspeaker.
