It adjusts, and charges to signal integration circuit 6, when the output valve of signal integration circuit 6 reaches the wake-up electricity of MCU control circuit 3
When pressing U, the work of MCU control circuit 3 is simultaneously decoded the doorbell data-signal of the demodulation output of high-frequency reception module 2, MCU control
Circuit 3 processed matches decoded doorbell data-signal with the doorbell data-signal prestored, and successful match drives doorbell defeated
Circuit 4 out, doorbell output circuit 4 drive doorbell to work again, and matching is unsuccessful, and MCU control circuit 3 does not export doorbell data letter
Number；Eight not searched out in the preamble signal of Doorbell Launcher 1 such as high-frequency reception module 2 during the working time are continuous
Pulse signal when, high-frequency reception module 2 work 0.8ms, suspend mode 28ms, in this condition, the output of signal integration circuit 6
3 wake-up voltage U of MCU control circuit, 3 suspend mode of MCU control circuit is not achieved in voltage；Therefore, this wireless doorbell operation of receiver electricity
It flows small.
In the implementation case:
1, high-frequency model is worked with duty cycle mode, suspend mode is entered after working time t1=0.8mS, after dormancy time t2=28mS
It automatically waking up, high-frequency model running current is 3.8mA, and quiescent current is less than 1uA (ignoring), when from dormancy awakening
Starting current 2mA starts time 0.4mS；
2, integrating circuit average current is 0.03mA；
3, other part circuit circuits, such as MCU control circuit, doorbell output circuit are very low in standby mode operating current, can
It ignores.
The calculating formula of power consumption are as follows: (3.8mA*0.8mS+2mA*0.4mS)/(28mS+0.4mS+0.8mS)+0.03mA ≈
0.16mA。
It rings a doorbell and is launched device daily and triggers 5 times, each ring time 8 seconds, average operating current 100mA is counted when jingle bell
It calculates, if No. 5 alkaline battery active volumes reach 2000mAH, every batteries can be calculated and use number of days are as follows: number of days=
2000mAH/ (0.16mA*24H+100mA*8S*5/3600)=408 day can reach battery and use the longevity under operating condition as above
Life 1 year or more.
