Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly and completely Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on this Embodiment in invention, the every other reality that those of ordinary skill in the art are obtained under not making creative work premise Execute example, broadly fall into the scope of protection of the invention.

Referring to Fig. 1～2, in the embodiment of the present invention, a kind of Internet of Things intelligence control system, including single-chip microcomputer U1, NAND gate Module II, microwave sounding module and photoelectric smoke detection module, described single-chip microcomputer U1 connects display module, keyboard mould respectively Block, NAND gate module I, NAND gate module II, watchdog module, power module, LED module, buzzer module, tight Call on urgently and make button module and GPRS module, NAND gate module I be also respectively connected with rpyroelectric infrared detecting module and microwave sounding Module, described NAND gate module II connects photoelectric smoke detection module, temperature sensing module and CO detecting module respectively；Institute Stating microwave sounding module and include antenna, resistance R1, electric capacity C1 and triode VT1, described antenna connects inductance L, electricity respectively Holding C1 and triode VT1 colelctor electrode, triode VT1 base stage connects the electric capacity C1 other end and potentiometer RP1 slide plate respectively, Triode VT1 emitter stage connects potentiometer RP1 one end, triode VT2 emitter stage and electric capacity C5 respectively, and potentiometer RP1 is another One end connects resistance R2, electric capacity C2, resistance R4, the electric capacity C5 other end and power supply VCC respectively, and the resistance R4 other end divides Not Lian Jie resistance R5, triode VT2 and output end vo, the resistance R5 other end respectively connecting triode VT2 base stage and electricity Holding C3, the electric capacity C3 other end connects the inductance L other end, the resistance R2 other end and the electric capacity C2 other end respectively；Described list Sheet machine U1 model is STC89C52；Described photoelectric smoke detection module uses infrared transmission module based on NE555；Described Temperature sensing module uses DS18B20；Described power module includes standby power supply module and direct power supply module.

The operation principle of the present invention is: refer to Fig. 1～2, once there be the emergencies such as people's burglary or breaking out of fire, Corresponding alarm detection module (rpyroelectric infrared detecting module, microwave sounding module, photoelectric smoke detection module, temperature Degree detecting module and CO detecting module) then send report to single-chip microcomputer U1 immediately by NAND gate module I and NAND gate module II Alert signal, single-chip microcomputer U1 receives the report for police service after signal, and GPRS module starts immediately, and remotely transmission alarm signal is to receiving terminal, If after unmanned releasing alert alert confirmation simultaneously is errorless after 50s, carrying out the acoustic scene (buzzer module) of event, light (LED mould Block) report to the police, and show corresponding dangerous situation information at display module, present system has probe failure warning function simultaneously, Avoid failing to report due to probe power down, report by mistake when breaking down, if it is determined that probe goes offline or is cut off, then sound and light alarm, Can go to release by the watchdog module trigger delay time (50s timer) when reporting to the police if there is false triggering, keyboard mould Block is used for arranging password and input password, only password correctly could manually release warning message.

Fig. 2 is operated according to Doppler effect: produced a fixing high-frequency signal (generally by local-oscillator circuit 400 800MHz), through aerial radiation to surrounding space, when having object of which movement in certain distance near antenna, high-frequency signal Will return to be received by the antenna again by passive movement object emission, make the frequency of oscillation of former oscillating circuit and signal amplitude produce change, This variable signal is integrated, amplify, compare etc. process after form control signal, deliver in single-chip microcomputer U1.

VT1 is produced from Induced Oscillation under the positive feedback effect of C1, and the frequency electromagnetic waves that vibration produces is empty by aerial radiation to surrounding Between, produce a three-dimensional microwave field in antenna surrounding, when there being object to move at this microwave field, object of which movement is reflected Electromagnetic wave is just received by the antenna, and makes the self-oscillatory amplitude of VT1 and frequency change, this change through by resistance R2 and The integrating circuit of electric capacity C3 composition becomes the voltage signal moved and fluctuate with object, and this voltage signal compares place through chip U1 After reason, produce and control high level, deliver in single-chip microcomputer U1.
