Description
Technical field
The utility model belongs to home appliance technical field, especially a kind of intelligent electric cooker human body proximity induction detection system.
Background technology
Human body proximity sensor (human body motion monitor), also known as contactless proximity transducer, is desirable electronic switch quantity sensor.The feature such as proximity transducer has that long service life, reliable operation, repetitive positioning accuracy are high, mechanical wearing and tearing, no-spark, noiselessness, vibration resistance are strong.Therefore, the range of application of proximity transducer is increasingly extensive, and the development of himself and the speed of innovation are also extremely rapid.Proximity transducer mainly comprises following types:
Infrared human body is close to inductor.In consumption, industry and automotive field application, many electronic systems are benefited from contactless feedback.IR provides a best approach close to being sensed as the system needing inspected object to exist.Also can be used for detecting the motion in maximum three dimensions close to induction, or even gesture.Its advantage is that static object also can detect, but its shortcoming to be distance of reaction near; Need to increase infrared window, can have an impact to some product appearances.
The human body proximity inductor of pyroelectricity original paper composition, be made up of the components and parts such as optical filter, FET, infrared induction source (pyroelectricity element), biasing resistor, EMI electric capacity, the Main Function of optical filter only allows wavelength to pass through at the infrared ray (IR wavelength that human body sends) of about 10 μm, and light, sunshine and other radiation are filtered, to suppress extraneous interference.Infrared induction source is made up of the pyroelectricity element of two series connection or parallel connection usually, the electrode of these two pyroelectricity elements is contrary, ambient background radiation almost has identical effect to two pyroelectricity elements, and the pyroelectric effect making it produce is cancelled out each other, and output signal is close to zero.Once have in people's intrusion detection region, human infrared radiation by part mirror focusing, and is received by pyroelectricity element, because angle is different, the heat that two panels pyroelectricity element receives is different, and pyroelectricity energy is also different, can not offset completely, after treated processing of circuit, export control signal.Its advantage is that distance of reaction is far away, can accomplish 6 ~ 10m; Its shortcoming is only to detect mobile object, and needs to increase lens, can have an impact to product appearance.
Ultrasonic sensor is the sensor utilizing hyperacoustic characteristic to develop.Ultrasonic wave is the mechanical wave of a kind of vibration frequency higher than sound wave, is occurred to vibrate to produce by transducing wafer under the excitation of voltage, and it has, and frequency is high, wavelength is short, diffraction phenomenon is little, particularly good directionality, ray and the features such as direction propagation can be become.Ultrasonic wave is very large to the penetrating power of liquid, solid, and especially in the opaque solid of sunlight, it can penetrate the degree of depth of tens meters.Ultrasonic wave is encountered impurity or interface and can be produced significantly to reflect to form and be reflected into echo, encounters live animal physical efficiency and produces Doppler effect.Scales based on Ultrasonic characteristics development is " ultrasonic sensor ", is widely used in the aspects such as industry, national defence, biomedicine.Ultrasonic sensor detection range is far away, but detection angle is little.
Microwave radar sensor is based on Doppler technology principle, adopt microwave special microprocessor, plane induction antenna, not only detection sensitivity degree is high, investigative range is wide, and work is very reliable, generally not reporting by mistake, steady operation in the temperature range can spent-15 ~+60, is that the human body proximity sensor circuit of infrared ray, ultrasonic wave, pyroelectricity element composition is in the past incomparable.
Human body proximity responds to extensive use every field, but, home appliance is seldom applied, does not especially apply especially on electric cooker.In today of scientific and technological develop rapidly, intelligent, automation is rooted in the hearts of the people, and people thirst for the control of electric cooker more flexible, such as, when human body proximity electric cooker, can realize automatic backlight Presentation Function.
