Abstract
The invention relates to an inductive detection sensor which is capable of detecting different kinds of natural disastrous weathers timely and accurately (as is shown in drawing 1) and applicable to burglary prevention of apartments and walls at the same time. A system of the device includes two parts: a light emitting head (II) and a light receiving head (I).
Description
Patent of the present invention relates to that a kind of energy is timely, sensor [Fig. 1] is found out in the induction of the various disaster weather of accurate detection, and its also can be applicable to the antitheft of apartment and enclosure wall simultaneously, all more advanced than the performance of existing detection diastrous weather and burglary-resisting installation.Along with national economic development, the disaster loss that many industries cause diastrous weather is huge, in the urgent need to there being a kind of equipment that can promptly and accurately find out disaster scenarios it to be born, to take measures in time, and the generation being against any misfortune.The enclosure wall in apartment also an urgent demand has one accurately, and durable equipment is the antitheft increase safe reliability of resident family.
Patent of the present invention is for designing in this case, and this induction is found out sensor [Fig. 1] and is made up of light emitting head [two] and light-receiving head [].
Light emitting head (two) is to manage (two) part in (5) composition diagram by high frequency oscillator (6) with LED, and high-frequency signal is modulated in DC voltage, lights LED pipe.The frequency of high frequency oscillator can the arbitrary frequency from 20-200KHz form, and concrete data need depending on task.The photochromic of luminotron also needs depending on task.For example: should select 20-40KHz for antitheft frequency, photochromicly should select infrared light, concrete photochromicly determine according to service condition.
Light-receiving head (one) partly, is made up of optical male lens (2) and photosensitive tube (1), and optical male lens, the light modulated of light transmitting terminal, focus on photosensitive tube, and sensitivity is determined by the requirement of photosensitive tube number.
Light emitting head (two) must be on same center line by dress with light-receiving head (), and (3) (4) are dust-break glass.
Claims (6)
1. sensor [Fig. 1] is found out in the induction that all diastrous weathers are found out in an induction, it is characterized in that being made up of light emitting head (two) and light-receiving head () two parts, and its center must be on same center line.
2. according to described in claim 1, sensor [Fig. 1] is found out in induction, it is characterized in that, light emitting head (two) part is made up of high frequency oscillator (6) and LED pipe (5) again; Light-receiving head (one) part is made up of optical male lens (2) and photosensitive tube (5).
3. according to described in claim 2, light emitting head [two] part, it is characterized in that: the frequency of high frequency oscillator (6) is the arbitrary frequency composition in 20-200KHz, concrete data need depending on task, and the high frequency producing with this oscillator (6) is modulated the electric current of LED pipe (5).
4. according to smooth emitting head claimed in claim 2 [two] part, it is characterized in that, LED pipe (5) photochromic, can need determine according to task, for example: photochromicly should select infrared light for antitheft.
5. according to described in claim 2, light-receiving head [] part, is characterized in that: photosensitive tube [1] be placed on the focus of convex lens [2] and the distance less than focus on, be mainly to allow light pass through convex lens [2] optically focused gone up reception effect to photosensitive tube [1].
6. according to described in claim 2, light-receiving head [] part, is characterized in that: the quantity of photosensitive tube [1] is determined by the requirement of sensitivity.
