In use, when gesture induction sensor 2 detects left and right gesture, interface is read by number and judges 5 He of amber light
Whether the actual condition value (WHITE, YELLOW) of white lamp 4 is all 0 (OFF state), if so, enabling 4 digital input value of white lamp be
1, i.e. white lamp 4 is lighted, and the actual condition value for recording white lamp 4 at this time is 1, realizes the arousal function of lamp.
When the working condition for carrying out white lamp 4 and amber light 5 differentiates, the two kinds of numbers of number and simulation for reading each lamp source are needed
Value.The number of white lamp 4 and amber light 5 is read respectively using the 4 of Arduino kernel control chips 1,7 two direct current input pins
State value, i.e. low and high level read simulation electricity of the white lamp 4 with amber light 5 respectively using~11 ,~10 two exchange input pins
It is pressed with valid value.When carrying out two lamp source working condition manipulations, using A1, two low and high level output pins of A2 carry out 2 lamp points
The bright control with extinguishing.The A4 of the low and high level delivery outlet SDA and Arduino kernel control chips 1 of gesture induction sensor 2 is defeated
Entrance is connected, and in actual operation, the judgement of gestures direction is carried out to carry out to A1, A2 poll tax on children by A4 mouthfuls of digital signals
Value operates to control the working condition of lamp.
When gesture induction sensor 2 detects left and right gesture, the virtual condition of amber light 5 and white lamp 4 is judged, if wherein one
A lamp actual condition value is 1 (illuminating state), then is 0 by its digital input value, i.e., extinguishes the lamp of this illuminating state, and record
The actual condition value of amber light 5 and white lamp 4 is all 0 at this time, realizes the extinguishing function of lamp.
When gesture induction sensor 2 detects gesture up and down, the actual condition value of amber light 5 and white lamp 4 is judged, if amber light
5 actual condition values are 1 (illuminating state) and the actual condition value of lamp 4 is 0 (OFF state) in vain, then to the pin data of amber light 5
Write-in value is 0, and the pin data write-in value of white lamp 4 is 1, that is, the light source for realizing amber light 5 to white lamp 4 switches.Record is yellow at this time
5 actual condition value of lamp is 0, and 4 actual condition value of white lamp is 1.If 4 actual condition value of white lamp is 1 (illuminating state), and amber light 5
Actual condition value is 0 (OFF state), then the pin data write-in value of dialogue lamp 4 is 0, and 5 pin data write-in value of amber light is
1, that is, the light source for realizing white lamp 4 to amber light 5 switches.4 actual condition value of white lamp is 0 to record at this time, and 5 actual condition value of amber light is 1,
Realize the function of switching lamp.
When hand is when distance is mobile, ultrasonic sensor 3 calculates distance by the time of back wave, and will be apart from conversion
At analog voltage, corresponding PWM wave is exported to the light source to work.Digital value on Arduino kernel control chips 1 is surveyed
Buret foot and the analogue value, which measure pin, can detect the 1 and 0 digital state value and voltage effective value of working condition light source.
Ultrasonic sensor 3 be delivery outlet ECHO and the Arduino kernel control chips 1 of pwm pulse~3 mouthfuls be connected
The average value for changing voltage with its PWM wave, controls the bright dark degree of lamp.The analog voltage delivery outlet DAC of ultrasonic sensor 3 with
The input ports A0 of Arduino kernel control chips 1 are connected.In actual operation, the analog voltage of A0 mouthfuls of inputs will be considered
Become the distinguishing rule to the actual working state of lamp for the effective voltage numerical value of lamp.
What is exported due to ultrasonic sensor 3 is PWM wave, the work that the pins of Arduino kernel control chips 1 is read out
The voltage when data that the analog voltage and digital voltage value of lamp source are read are end-of-pulsings, perseverance are 0, are not used as work shape
The judgement of state just considers the analog voltage for directly using ultrasonic wave to pass back as the foundation of lamp working condition.
Ultrasound must measure the conversion formula of time and actual range：
Wherein, s is hand at a distance from ultrasonic wave module, and t is the time difference for sending out and receiving the acoustic signals being reflected back,
340m/s is ultrasonic propagation velocity.
The analog voltage conversion formula that distance is exported with ultrasonic wave：
D=s*0.68 (v)
Wherein, D is the analog voltage of ultrasonic wave output, and s is hand at a distance from ultrasonic wave module.
The conversion formula of voltage effective value is：
Wherein, D is the analog voltage of ultrasonic wave output, and d is the voltage effective value of lamp.
It refers to shown in attached drawing 6, is found by testing inspection, during brightening this by very dark, brightness increases
Slowly, use feeling is influenced in use.To solve the problems, such as this, propose to press voltage value using the thought of non-uniform quantizing
Detect apart from Non-uniformed mapping at 4 parts, be segmented assignment in varing proportions.So that in the propagation process from 0-2.4v, hand
Gesture can realize brightness change largely to remote mobile smaller distance.
In conclusion the present invention realizes that the wake-up and extinguishing of lamp, upper and lower gesture realize that the light source of lamp is cut by left and right gesture
It changes, far and near gesture realizes the brightness regulation of lamp, is mainly used for study and work occasion, and light source is selected with white light to give tacit consent to light source,
Addition yellow light sources are provided in occasion of having a rest.
The foregoing is merely the preferred embodiment of the present invention, are not intended to limit the scope of the invention, every utilization
