Description
Technical field
The utility model relates to a kind of repeater, refers to a kind of low-consumption wireless remote-controlled doorbell repeater especially.
Background technology
Existing household radio remote-controlled doorbell, is made up of reflector and receiver two parts usually.Reflector by coding circuit, modulation circuit, radio frequency transmitter circuitry and antenna four part form; Receiver is made up of antenna, radio-frequency (RF) receiving circuit, decoding circuit, music module circuit and loud speaker five part.Its modulation system generally adopts amplitude-shift keying (ASK) to modulate.By the constraint of device technical indicator and the country laws and regulations requirement to wireless device frequency range and power, the control range of wireless remote control doorbell reflector is limited, usual maximum distance is open field 300 meters, the out of contior reason of its reflector overlength distance is as follows: the rf modulated signal that reflector sends, increase along with distance is constantly declined, finally can be equal to or less than the white noise in the external world.When rf modulated signal after this crosses high attenuation and white noise are received by the receiver, if its power is still higher than the sensitivity of receiver, then receiver carries out demodulation, but the signal demodulated because be subject to extraneous white noise impact and with launch geocoding inconsistent, cannot the music module circuit working of trigger receptors, so doorbell sound can not be sent.Now, if there is more remote demand for control, existing wireless remote control doorbell cannot meet.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of novel low-consumption wireless remote-controlled doorbell repeater, to meet the demand of the farther control range of wireless remote control doorbell.
The technical solution of the utility model is achieved in that a kind of low-consumption wireless remote-controlled doorbell repeater, comprise reflector and receiver, it is characterized in that: also include the repeater with reflector and receiver wireless connections, this repeater comprises micro-control circuit, power circuit, receiving circuit and radiating circuit, power circuit respectively with micro-control circuit, receiving circuit and radiating circuit connect, micro-control circuit is also connected with holder and LED, receiving circuit is connected with the reception antenna for Received signal strength, radiating circuit is connected with the transmitting antenna for transmitting.
Be preferably, described reflector comprises coding circuit, modulation circuit, radio frequency transmitter circuitry and the first antenna, and coding circuit, modulation circuit, radio frequency transmitter circuitry and the first antenna connect successively along signal transmission direction.
Be preferably, described receiver comprises antenna, radio-frequency (RF) receiving circuit, decoding circuit, music module circuit and loud speaker, and antenna, radio-frequency (RF) receiving circuit, decoding circuit, music module circuit and loud speaker connect successively along signal transmission direction.
By adopting technique scheme, add repeater, and the holder in repeater effectively stores the rf modulated signal in reflector and transmits, make rf modulated signal through the transmission of intermediate station, effectively avoid rf modulated signal signal strength weakening in transmitting procedure, thus ensure that the requirement of long-distance transmissions.

Fig. 2 is transmitter circuit theory diagram in the utility model embodiment;
Fig. 3 is acceptor circuit theory diagram in the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Fig. 1-Fig. 3, the utility model discloses a kind of low-consumption wireless remote-controlled doorbell repeater, comprise reflector and receiver, in the utility model specific embodiment, also include the repeater with reflector and receiver wireless connections, this repeater comprises micro-control circuit 1, power circuit 2, receiving circuit 6 and radiating circuit 3, power circuit 2 respectively with micro-control circuit 1, receiving circuit 6 and radiating circuit 3 connect, micro-control circuit 1 is also connected with holder 5 and LED 4, receiving circuit 6 is connected with the reception antenna 7 for Received signal strength, radiating circuit 3 is connected with the transmitting antenna 8 for transmitting, wherein micro-control circuit 1 can detect power circuit 2 voltage, when voltage is lower than definite value time, triggering LED 4 is not stopped flicker by micro-control circuit 1, and repeater adopts low consumption circuit design, and all devices all have sleep pattern, and under sleep pattern, current drain is less than 1mA, reach 700uA, by micro-control circuit other circuit waken up and control with sleeping.
In the utility model specific embodiment, described reflector comprises coding circuit 11, modulation circuit 10, radio frequency transmitter circuitry 9 and the first antenna 20, and coding circuit 11, modulation circuit 10, radio frequency transmitter circuitry 9 and the first antenna 20 connect successively along signal transmission direction.
In the utility model specific embodiment, described receiver comprises antenna 12, radio-frequency (RF) receiving circuit 13, decoding circuit 14, music module circuit 15 and loud speaker 16, and antenna 12, radio-frequency (RF) receiving circuit 13, decoding circuit 14, music module circuit 15 and loud speaker 16 connect successively along signal transmission direction.
At this low-consumption wireless remote-controlled doorbell repeater in use, user can use multiple repeater simultaneously, just can realize controlling more at a distance.
By adopting technique scheme, add repeater, and the holder in repeater effectively stores the rf modulated signal in reflector and transmits, make rf modulated signal through the transmission of intermediate station, effectively avoid rf modulated signal signal strength weakening in transmitting procedure, thus ensure that the requirement of long-distance transmissions.
The operation principle of this low-consumption wireless remote-controlled doorbell repeater is as follows: first, and reflector carries out learning code with repeater and receiver respectively, the geocoding of repeater and receiver difference stored transmit device.During work, reflector sends the rf modulated signal with geocoding, repeater receives and this modulation signal of demodulation, obtain geocoding, if the geocoding received is identical with the geocoding stored, then repeater forwards this geocoding, send rf modulated signal by code modulated circuits and radio frequency transmitter circuitry to realize forwarding, receiver detects this rf modulated signal and after demodulation, if the geocoding demodulated is identical with the geocoding stored, then trigger music module circuit working, send doorbell sound.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
