Embodiment
Key of the present invention is to have adopted first in the complete machine structure circuit of television set rpyroelectric infrared sensing element PIR to form an ambient condition observation circuit.This probe is a target to survey human body radiation, so be that infrared radiation about 10 μ m is very responsive to wavelength.To the sensitive for infrared radiation of human body, on the window that infrared-ray passes, be coated with special Fresnel filter for only on its structural design usually, make the interference of environment be subjected to the obvious control effect.Form a sphere by the Fresnel filter, form a lot of little forms, each form is exactly a monitoring direction.This transducer comprises the pyroelectricity element of at least two mutual serial or parallel connections, two electric polarization directions of this element are just in time opposite, ambient background radiation almost has identical effect to two pyroelectricity elements, makes its generation release electrical effect and cancels out each other, so the output of detector no signal.The people enters in the search coverage, and human infrared radiation focuses on by partial mirror, and is received by pyroelectricity unit, but two heat differences that pyroelectricity unit receives, and pyroelectricity is also different, can not offset, thereby judge have the people to enter through signal processing.Over against little form receive the infrared ray of human body emission, form a high potential.This time, internal circuit is output signal not when being in high potential or electronegative potential always, was judged as unmanned moving.When human body moved, the people disappeared from the detection range of a little form, arrive another little form, thereby the current potential that formed the little form of high potential originally drops to electronegative potential, forms a decline and prolongs, and sends a signal, thereby judged that the people is moving.So adopt above element to collect information exactly to ambient condition, and by after the back-end circuit processing signal that monitors being sent to the I/O port of the CPU in the television set, by image and the sound adjustment circuit 3 of after Control Software procedure identification in the television set CPU2 internal memory and the judgement adjustment signal being sent into television set, thus the intelligent management behind the enforcement man-machine communication to television set.This ambient condition supervisory circuit is made up of the ambient signal treatment circuit 1 of so highly sensitive pyroelectric infrared sensor PIR and design supporting with it.This signal processing circuit 1 should be by amplifying circuit 1A as being barricaded as with discrete component, voltage comparator circuit 1B and output signal match circuit 1C form at pyroelectric infrared sensor PIR polyphone in regular turn, pyroelectric infrared sensor PIR delivers to this circuit through voltage amplification with the infrared signal of the mobile human body that collected, more adaptive after the output of output circuit 1C is delivered to the I/O port input of television set CPU2, after software is judged, be converted into regulating command and send image and the sound adjustment circuit 3 of delivering to television set from the CPU2 corresponding port.
Fig. 2 has provided the embodiment of ambient condition observation circuit further, and the model that the red transducer of pyroelectricity adopts among this embodiment is the RE200B integrated circuit block.The ambient signal treatment circuit 1 that matches adopts the CS9803 integrated circuit (IC) chip, and this integrated circuit (IC) chip is 16 pin plastic packaging types.Inside is made up of system clock, two stage amplifer, voltage comparator, detector, timer, zero-crossing detector and output control circuit, meets the supporting requirement with pyroelectric infrared sensor RE200B fully.Integrated environment status monitoring circuit is then formed by infrared sensor RE200B and integrated circuit CS9803 and supporting peripheral Resistor-Capacitor Unit overlap joint thereof.Wherein the required standard operation voltage of infrared sensor RE200B is to be delivered to by the 4th pin of integrated circuit CS9803, the signal that infrared sensor RE200B is collected is delivered to the crus secunda of integrated package CS9803, amplify through this integrated package internal circuit two utmost point computings, window voltage relatively back is sent I/O port to television set CPU2 from signal output part the 11st pin.
More than designed circuit after television set enters normal operating conditions, promptly enter the start time-delay stage, infrared ray sensor RE200B adds electric preheating and promptly enters automatic detected state after 45 seconds.There is the people seeing TV in the room, then human body is sent out that the infrared ray of releasing will be detected and the signal that the signal that collects is converted into 1mv, 3-7HZ is sent into the CS9803 crus secunda, after two-stage is amplified comparison process by the I/O port of output circuit from high level of 11 pin output to television set CPU.In conjunction with start process, through software program be judged to be normally see tv state after CPU command adapted thereto port do not send regulation and control instruction, then by the time-delay after enter a sampling period.As the people behind the sleeping or signal of back infrared ray sensor RE200B collection of leaving away less than mobile human body, signal from 11 human hair combing wastes of CS9803 toward television set CPU corresponding port becomes and continues high or low level, and the signal of taking this moment is judged for the people through software and fallen asleep or left away.This moment, CPU did not send shutdown command immediately, but sent regulation and control instruction under software administration, made the image deepening of television set, and volume reduces, and waited for environment reaction, and then entered the next cycle sampling.If next periodic sampling comes to the same thing, then the circuit for regulating and controlling 4 of television set can make volume continue downward modulation under the cpu instruction of television set, until last closing television machine.The time cycle of regulation and control and sampling can be by software set, and is sleeping or come back to when watching TV in the room and can close above circuit in case of necessity with the hand adjustment control to return to normal rating state as the people, enters complete manual operation.Above circuit makes television function hommization more, and television set is under the intellectualized management, increases the service life and avoids unnecessary loss.
A function conversion circuit is set in the ambient condition observation circuit, and it can make function of the present invention further be expanded.Function conversion circuit is actually a power supply switch circuit, and a doubly-linked third gear mains switch K is arranged in the power circuit of environmental monitoring circuit more precisely.The ambient condition observation circuit did not have the power supply supply to quit work when it was in neutral position 1-1.This moment, television set entered fully artificial state of a control.When K switch forwards the 2-2 shelves to, the V in the television set
DDDC power supply loads, and the ambient condition observation circuit of being set up enters operating state, exports the mobile human body infrared signal that is collected to the CPU of television set.This moment, television set was in the human body induction control state, and owner can leave away arbitrarily or arbitrarily sleep, and the TV of needn't worrying to wake up from a sleep morning is still in work.When K switch was in 3-3 shelves state, we were referred to as anti-theft state.The V of this moment
DABe to be in the DC power supply that the CPU under the shutdown electricity-saving state draws, also claim holding state by television set.This moment, the ambient condition observation circuit was a dual power supply, the direct current V that draws except CPU under the holding state
DA, also provide independent current source BT for oneself for one in parallel outward, it is a rechargeable battery pack.In running order ambient condition observation circuit still can detect mobile human body by pyroelectric infrared sensor PIR at this moment and enter within doors, and with the signal that collects by 11 human hair combing wastes of CS9803 I/O port to television set CPU, this signal can start CPU, change operating state immediately over to by electricity-saving state, after CPU handles K switch state-detection and time-delay (in case owner drops in TV Room night), can judge after the robber enters the room and instruction can be sent, trigger television is opened, channel searching also progresses into the max volume state, the robber is played shake take the photograph effect.Television set CPU sends the work of instruction triggers warning circuit from the I/O port and sends chimes of doom when volume is enlarged to the limit, or the message that suffers people's invasion in the room passed to security personnel by other isolated plant or cause bedroom people's the vigilance of sleeping soundly, or reach master cellular phone and report to the police.
