The Main Function of optical filter is only to allow wavelength infrared ray (Infrared wavelength that human body sends) about 10 μm to pass through, and light, sunlight and other radiation is filtered, with the interference that suppression is extraneous.Infrared induction source is generally made up of two pyroelectricity elements in series or in parallel, the electrode of the two pyroelectricity element is contrary, ambient background radiation almost has identical effect to two pyroelectricity elements so that it is the pyroelectric effect of generation is cancelled out each other, and output signal is close to zero.In once having people's intrusion detection region, human infrared radiation is focused on by partial mirror, and is received by pyroelectricity element, owing to angle is different, the heat that two panels pyroelectricity element receives is different, and pyroelectricity energy is the most different, can not be completely counterbalanced by, after treated processing of circuit, export control signal.Pyroelectric effect is similar to piezoelectric effect, refers to cause the phenomenon of plane of crystal electric charge due to the change of temperature.Pyroelectric infrared sensor is made up of ceramic oxide or piezolectric crystal unit, electrode is made on two surfaces of element, when in the range of Sensor monitoring, temperature has the change of △ T, pyroelectric effect can produce electric charge △ Q on two electrodes, produces a faint voltage △ V the most between electrodes.Owing to its output impedance is high, a field effect transistor is had to carry out impedance transformation in the sensor.Produced by pyroelectric effect, electric charge △ Q can be combined by the ion in air and disappear, and i.e. when ambient temperature-stable is constant, △ T=O, sensor is without output.Human body or the bigger animal of volume have constant body temperature, general at 37 degree, so the infrared ray about specific wavelength 10 μm can be sent, when human body enters detection zone, because human body temperature and ambient temperature have difference, infrared ray about 10 μm of human-body emitting gathers on infrared induction source (pyroelectricity element) after being strengthened by Fresnel lens optical filter, infrared induction source will lose charge balance when receiving human infrared radiation, outwards discharge electric charge, and then produce △ T and △ T circuit to the periphery is exported, subsequent conditioning circuit just can produce execution signal after processing after testing.
Further: the drain electrode of described field effect transistor is provided with EMI electric capacity with ground end.On the one hand the magnitude of voltage that drain electrode export can be made close to constant, and it exports the impact being susceptible to magnetic disturbance.
Further: described fet gate is provided with biasing resistor with ground end.It is current signal owing to electrocaloric effect creates signal, so arranging a resistance by the grid of scene effect pipe with ground end, current signal can be converted into voltage signal, and the threshold values of its conducting can be regulated by the resistance of regulation biasing resistor, namely regulate the sensitivity of pyroelectric infrared sensor, simple in construction, it is easy to accomplish.
Further: described pedestal is additionally provided with grating sensor, described grating sensor is arranged towards described cutting die holder, and when one grating sensor is blocked, described pyroelectric sensor obtains electric work.Due to pyroelectric sensor, if to be continuously in the energy consumption that duty easily produces relatively big, and work long hours and affect this sensor service life, so carrying out pre-detection by grating sensor, it is ensured that using effect, plays the purpose of energy-conserving and environment-protective.
Further: described pyroelectric sensor has been also coupled to warning circuit, described warning circuit includes stand by lamp, and when described pyroelectric sensor detects biological thermal source, described stand by lamp works.By warning circuit and the design of stand by lamp, it is ensured that user can comparatively fast leave danger position.
Further: described grating sensor is coupled with indicating circuit, described indicating circuit includes display lamp, and when one grating is blocked, described display lamp works.By so arranging, it is ensured that operationally, display lamp plays reminding effect to pyroelectricity element.
In sum, this utility model is had the advantages that 1, be ensure that the safety of operator by pyroelectricity technology；2, relatively low use power consumption；3, interactivity is higher.
