Detailed description of the invention

Refer to Fig. 1～Fig. 5, Multifunctional intelligent desk lamp control circuit, including MCU module 1, power module 2, key-press module 3, bluetooth module 4, pyroelectricity module 5, LED drive module 6, mobile phone 7.The outfan of power module 2, the output of key-press module 3 End, the outfan input with MCU module 1 respectively of the outfan of bluetooth module 4, pyroelectricity module 5 are connected；MCU module 1 Outfan is connected with the input of LED drive module 6；Bluetooth module 4 and mobile phone 7 can set up wireless connections by bluetooth；Power supply The output of module 2 respectively with the power input of MCU module 1, the power input of key-press module 3, the power supply of pyroelectricity module 4 Input, the power input of bluetooth module 5, the power input of LED drive module 6 are connected.

MCU module 1 described in the design by Chip Microcomputer A tmega8, download program mouth, electric source filter circuit, reset circuit, Power supply indicator, crystal oscillating circuit form.In system, Chip Microcomputer A tmega8 is responsible for the input collection of system, program performs and output Refresh, and other various piece belongs to the peripheral circuit of single-chip microcomputer, for the properly functioning offer condition of single-chip microcomputer.Wherein, P2 Mouth, the electric source filter circuit of C4, C5 composition single-chip microcomputer, the reset electricity of R2, S1, C3 composition single-chip microcomputer is downloaded for Single Chip Microcomputer (SCM) program Road, the power supply indicator of R3, D2 composition MCU module, XT1, C6, C7 form single-chip microcomputer crystal oscillating circuit.

Power module 2 described in the design is by AC/DC module U4, LM7805 voltage stabilizing chip U2, REG1117-3.3V voltage stabilizing Chip U3 forms.Wherein the alternating current of the function time 220V of AC/DC module changes into the unidirectional current of 12V, carries to LED drive module For the DC source of 12V, meanwhile, the DC source of 12V is by after voltage stabilizing chip LM7805 and REG1117-3.3V, by unidirectional current Pressure will become 5V and 3.3V, and wherein MCU module, key-press module, pyroelectricity module are that 5V powers, and bluetooth module is that 3.3V powers.

Key-press module 3 described in the design is made up of 4 identical key circuits, and each circuit is upper by a 10K's Pull-up resistor and a self-recoverage button are constituted.Under normal circumstances, button is off, and now circuit output end is by pull-up Resistance is connected to VCC, is output as high level, and when the button is pressed, output port connects GND, is output as low level.Press for 4 A key circuit corresponding function respectively is: switch, mini light night, brightness adds, brightness subtracts.

What bluetooth module 4 described in the design and pyroelectricity module 5 used is all ready-made sensor, is SPP-C respectively Bluetooth module and HC-SR501 pyroelectric sensor, because this two parts sensor technology is the most highly developed, and module Volume is little, application is simple, applies ready-made sensor at this, can greatly reduce development difficulty.Wherein, SPP-C bluetooth module Connection with MCU module only need to can realize communication by serial ports, between HC-SR501 pyroelectric sensor and MCU module then Only needing an I/O can realize communication, when there being people's activity, I/O level is high, and when nobody's activity, I/O level is low.

LED drive module 6 described in the design, is made up of comparator and power amplifier two parts, wherein, and comparator electricity Route R8, RP1, U7 composition, power amplification circuit is made up of R9 and Q1.This circuit input end is that the forward of comparator LM358 is defeated Entering end, input signal is the road pwm signal that single-chip microcomputer produces, and the amplitude of pwm signal is first changed into 12V, then by comparison circuit LED bulb is directly driven after signal power being amplified by the power amplifier being made up of audion TIP142.By this Method controls LED bulb, both can reach the effect of light modulation, and can reach again the effect of eye protection.

Mobile phone 7 described in the design, indication is a being mounted with and the Android mobile phone of APP that this design is supporting, and APP has There is a following functions:

1. long bluetooth of pressing connects button, can eject connection equipment choice dialog box.

2. can set timing by stirring the thin code switch in the upper left corner, APP interface, the longest timing is 23:59, After mixing up timing, press the alarm clock in the upper right corner and i.e. can turn off the light function with the timing of firing platform lamp.

3. click on the power knob in APP interface and can change the current state of desk lamp, i.e. turn on light and become turning off the light, change of turning off the light For turning on light.

4. click on the moon shape button in APP interface, the sleep pattern of desk lamp can be started, i.e. when band lamp is closed, platform Lantern festival has detected whether that people is movable automatically, and in the case of having people's activity, desk lamp can be turned on light automatically.
