The Acoustic control cradle circuit of the present invention can rock cradle by sound-detection and control, mitigate the negative of parent
Load promotes baby sleep, and can also detect whether child covers quilt, and child is avoided to catch a cold.
Specific embodiment with reference to embodiments is described in further detail the above of the present invention again.
But the scope that this should not be interpreted as to the above-mentioned theme of the present invention is only limitted to following example.Think not departing from the above-mentioned technology of the present invention
In the case of thinking, the various replacements or change made according to ordinary skill knowledge and customary means should all be included in this hair
In bright scope.
Description of the drawings
Fig. 1 is the circuit diagram of Acoustic control cradle circuit of the present invention.
Specific embodiment
The Acoustic control cradle circuit of the present invention as shown in Figure 1 has the sound being connected with the input terminal of the microcontroller U1 of 89C51 types
Tone detection circuit and the relay circuit being connected with the control terminal of microcontroller U1.The reset terminal of microcontroller U1 is connected with reset key
S4.The clock end of microcontroller U1 is connected with crystal oscillator Y1.Have in the sound detection circuit microphone MIC that is connected and
Cascade transistor circuit.There is the first triode Q1 that base stage is connected with the microphone MIC in transistor circuit is cascaded, the
The collector of the emitter ground connection GND of one triode Q1, the base stage of the second triode Q2 and the first triode Q1 meet power supply VCC,
Emitter ground connection GND, the collector of second triode Q2 connect the input terminal of the microcontroller U1.Have in relay circuit
The output terminal of the relay K being connected with the control terminal of the microcontroller U1, relay K are connected with the motor that control cradle shakes.
The setting port of microcontroller U1 switchs S2 and confirms switch S3 when being connected with added-time switch S1, subtracting, convenient for parent to shaking cradle
Time be configured, and shown by the display module DSP that the display output terminal of microcontroller U1 connects.Microphone
MIC for collecting the sound that child sends, if child groan cry or cry if sound it is larger, microphone MIC is by voice signal
Judged after reaching microcontroller U1 by microcontroller U1 according to the volume threshold (such as 40db) of setting, if it exceeds the threshold, single
Then closing relay K, startup motor shake cradle to piece machine U1.After volume is less than volume threshold, microcontroller U1 controls disconnect
Relay K stops shaking cradle.
In order to detect whether child covers quilt, the I/O ends of microcontroller U1 are also associated with ultrasonic output circuit, microcontroller
