Abstract

The utility model discloses a multi-function sensor having a 360DEG omnibearing rotary sensing function and a self displacement sensing function. Integrating infrared shake sensing and omnibearing rotary driven pyroelectricity sensing organically, the sensor of the utility model provides a new sensing device for alarm systems increasingly and widely applied.

Description

Multi-function sensor

The utility model relates to sensing technology, more specifically to a kind of Multifunction Sensor that utilizes infrared sensing and shake sensing to realize the comprehensive sensing of rotation.

There are deficiencies such as alarm range is little, shortage self-protection ability in the infrared sensor of prior art, and for example, conventional passive infrared sensing has angle limitations, and does not possess the ability that detection sensor itself is subjected to displacement or is vibrated.

The purpose of this utility model is to provide a kind of and overcomes the multi-functional infrared sensor that prior art infrared sensor visual angle is limited and do not possess self-sensing function deficiency, but promptly the multi-functional infrared sensor that provides of the utility model not only the visual angle is big but also possess the ability that detection sensor itself is subjected to displacement or is vibrated.

The purpose of this utility model is to realize like this, construct a multi-functional infrared sensor and comprise base 1, place the column 2 on the base 1, be contained in the bearing 3 at column 2 tops, rotatably be connected the rotating head 4 of described column 2 tops by bearing 3, place described rotating head 4 tops to be used to drive the motor 5 of its rotation, the described rotating head 4 one ends sealing other end is open, the optical male lens 7 that an open end is provided with protective layer 6 and is arranged on protective layer 6 inboards, focal position at optical male lens 7 described in the described rotating head 4 is provided with a catoptron 8, and described column 2 is provided with a pyroelectric infrared-sensing module 9 that can receive from described catoptron 8 reflected infrareies; Described base 1 is a light tight sealing rectangular box, bottom surface middle position in this case is provided with infraluminescence pipe 10, and this case inner top surface inwall and described infraluminescence pipe 10 relative positions are provided with infrared receiving tube 11, be provided with the logical window 12 of its lead to the hole site and described infraluminescence pipe 10 and receiving tube 11 light in line by the end face closer locations in this case, the logical other parts of window 12 except through hole of this light can intercept infrared light and pass through; At the logical window 12 of described light and be equipped with sphere optical window 13 that the material by intercepting infrared light that also is provided with concave surface center up between the bottom surface of infraluminescence pipe 10 and has through hole makes and fit tightly the plated film plastic layer 14 of belt track groove together with sphere optical window 13, the home position of described sphere optical window 13 is provided with a smooth through hole, be processed with the loose slot that it is centered close to described smooth through hole on the described plated film plastic layer 14, on described sphere optical window 13 and plated film plastic layer 14, also place one can free-moving diameter greater than the shake steel ball 15 of described smooth through hole.

Multifunction Sensor of the present utility model is characterized in that the inwall of described round column 2 is provided with reflection horizon 16 all around.

Multi-functional infrared sensor of the present utility model is characterized in that the rail groove on the described plated film plastic layer 14 can be that a straight line distributes, and also can be that sigmoid curve distributes.

Implement multi-functional infrared sensor of the present utility model, thereby can expand sensing scope greatly by the 4 comprehensive 360 ° of rotations of electric rotating machine 5 driven in rotation, simultaneously owing to be provided with the infrared shake sensing that is located in the base, increased the function of sensor to self displacement or vibration perception.

In conjunction with the accompanying drawings and embodiments, the utility model is described in further detail, in the accompanying drawing:

Fig. 1 is the structural representation of the utility model Multifunction Sensor;

Fig. 2 is a kind of structural relation synoptic diagram of plated film plastic layer 14 and shake steel ball 15 in the utility model Multifunction Sensor base 1;

Fig. 3 is the another kind of structural relation synoptic diagram of plated film plastic layer 14 and shake steel ball 15 in the utility model Multifunction Sensor base 1;

Fig. 4 is the cut-open view of obtaining at central point direction straight line along movable rail among Fig. 2 and Fig. 3; And

Fig. 5 is along the cut-open view of obtaining at the straight line of central point direction perpendicular to movable rail among Fig. 2 and Fig. 3.

Referring to Fig. 1, because motor 5 driven in rotation 360 ° of comprehensive rotations of 4 dos, the infrared signal of any angle (for example human body invasion) but scioptics 7 answer module 9 through catoptrons 8 by rpyroelectric infrared and received, first output signal of sensor is provided by this module 9, owing to, overcome the limited deficiency in prior art sensor visual angle with moving Dai Jing.Again owing in sensor base 1, be provided with the shake sensing, promptly sensor not when displacement or shake infraluminescence pipe 10 just in time hidden during the through hole of the infrared light of sending out by sphere optical window 12 and make the output of infrared receiving tube 11 no signals by steel ball 15, when displacement of sensor own or shake, the steel ball 15 that is on sphere optical window 13 and plastic layer 14 through holes departs from through hole along track on the plastic layer 14, infraluminescence pipe 10 infrared light of sending out is received by infrared receiving tube 11, form second output signal of this sensor.

Fig. 2 and Fig. 3 are respectively two kinds of movable rail on the plated film plastic layer 14, this track length center be one with the relative through hole of spherical optical window 13 through holes.

Shown in Fig. 4,5, steel ball 15 pillows on the groove of plated film plastic layer and does not contact with light hole preventing that steel ball part injection light hole from forming intersection under the normal condition, thereby has improved sensitivity, and steel ball has not blocked light hole when being subjected to displacement or shake.
