The purpose of this utility model is to provide a kind of digital alarm clock by gesture induction control night-light, above-mentioned to solve
The problem of being proposed in background technology.
To achieve the above object, the utility model provides following technical scheme：It is a kind of that night-light is controlled by gesture induction
Digital alarm clock, including microprocessor, LCD display, photoreceptor and infrared emission, receiving interface, the output of the microprocessor
End and the input of LCD display are electrically connected with, and the input of the microprocessor and the output end of button are electrically connected with, described
The input electricity of the electric connection of the input of microprocessor and the output end of power supply, the photoreceptor output end and microprocessor
Property connection, the output end of the microprocessor and the input of night-light driver be electrically connected with, the infrared emission, receiving interface
It is electrically connected with microprocessor, the electric connection of the output end of the microprocessor and the input of loudspeaker.
It is preferred that, the microprocessor is MSP430F5438 process chips.
It is preferred that, the photoreceptor is the probe for being built-in with pyroelectric infrared sensor.
It is preferred that, the night-light driver is taken to be a kind of using common pulse-width modulation PWM chip combination peripheral circuit
Build the LED drive circuit of controllable silicon light modulation.
Technique effect of the present utility model and advantage：This controls the digital alarm clock of night-light by gesture induction, adds logical
Gesture induction is crossed opening/close night-light, use of the user at night is very easy to, the need for meeting market development.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is microcontroller circuit figure of the present utility model；
Fig. 3 is pyroelectric infrared sensor circuit diagram of the present utility model；
Fig. 4 is night-light drive circuit figure of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
The utility model provides a kind of digital alarm clock by gesture induction control night-light as Figure 1-4, including
Microprocessor, LCD display, photoreceptor and infrared emission, receiving interface, the output end and LCD display of the microprocessor
Input be electrically connected with, the output end of the input of the microprocessor and button is electrically connected with, the microprocessor it is defeated
Enter end and the electric connection of the output end of power supply, the input electric connection of the photoreceptor output end and microprocessor is described
The output end of microprocessor is electrically connected with the input of night-light driver, the infrared emission, receiving interface and microprocessor
It is electrically connected with, the electric connection of the output end of the microprocessor and the input of loudspeaker.
As shown in Fig. 2 microprocessor uses MSP430F5438 process chips, clock circuit frequency is 16MHz, by right
Chip carries out programming and burning, controls the collection and processing of whole strain signal.
As shown in figure 3, the photoreceptor is the probe for being built-in with pyroelectric infrared sensor, the probe uses chip
BISS0001 is equipped with pyroelectric infrared sensor KBS-6B and a small amount of outward element constitutes passive type infrared human body sensor, plus
Dress Fresnel Lenses substantially increases detection range, and human testing demand is met well.When human hand is passed from rpyroelectric infrared
Sensor by when, BISS0001 V0 mouths export a direct impulse, note that microprocessor driven night-light driver opens night-light.
As shown in figure 4, night-light driver is built to be a kind of using common pulse-width modulation PWM chip combination peripheral circuit
The LED drive circuit of controllable silicon light modulation, it maintains current compensation circuit by detecting the terminal voltages of R 1（That is input current）To control
Flow through the electric current for maintaining current compensation circuit.When input current is smaller, maintain to flow through larger electric current on current compensation circuit；
When input current is larger, current compensation circuit shut-off is maintained, maintains current compensation to ensure controllable silicon in the form of constant-current source
Maintain electric current.Adjusting control circuit includes comparator, R C charge-discharge circuits and gain circuitry.A knob row is selected in experiment
The controllable silicon dimmer that journey and copped wave angle are directly proportional, its minimum angle of flow is about 30 °.
Operation principle：The RF transmitter that the utility model is built in alarm clock outwards launches infrared ray at any time, meanwhile,
The infrared receiver being built in alarm clock also receives the infrared ray in the external world at any time；When the infrared light of transmitting is lived by stick shift,
Part infrared ray will be reflected back, and receiver is received after the infrared ray for returning and being emitted back towards and, and note that microprocessor opens night
Lamp.In order to save electricity consumption, the also built-in sensor devices of alarm clock, ambient light for detecting outside is infrared when there is visible ray
Transmitting, receiving module do not work；When in dark surrounds, infrared emission, receiving module are started working.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, this is not limited to
