As shown in Figures 3 to 5, which can use the materials such as timber, plastics, metal to be made.It includes first
Main body 1211 and the second main body 1212 being detachably connected with first main body 1211.By first main body 1211 and it is somebody's turn to do
Second main body 1212 is detachably connected to facilitate dismounting or installation second group sensor.The mounting bracket 10 include with this first
The second sensitive surface 1213 that sensitive surface 111 is set into set angle.Specifically, which is arranged on the second shell
On the side wall of body 12, then second sensitive surface 1213 is located on different faces from first sensitive surface 111 so that this first
Group sensor is different from the region that the second group sensor senses.
Second sensitive surface 1213 is equipped with limit light groove 122, and the width of the limit light groove 122 is less than the second group sensor
Sense angle；And the depth of the limit light groove 122 is more than its width, then it can limit the sensing angle of the second group sensor,
Reduce the monitoring area of the second group sensor.In the present embodiment, which is in rectangular-shape.Specifically, the limit light
Groove 122 is arranged in first main body 1211, and from the long side of first main body 1211 to another length of first main body 1211
Side extends.
Second sensitive surface 1213 be equipped be adapted with the optical lens sizes of the second group sensor and with the limit light
Second group of mounting hole 123 that groove 122 connects；Specifically, which is arranged in second housing 12, into one
Step ground, second group of mounting hole 123 are arranged in second main body 1212.First group of mounting hole 123 includes being disposed side by side on
The 3rd mounting hole 1231 and the 4th mounting hole 1232 in second sensitive surface 1213.3rd mounting hole 1231 and the 4th peace
Dress hole 1232 is arranged side by side in longitudinal direction.The aperture of 3rd mounting hole 1231 and the 4th mounting hole 1232 and first group of sensing
The diameter of the optical lens of device is roughly equal.In some other embodiment, the quantity of second group of mounting hole 123 is not limited to two
A, it can be for one, three, four or multiple.
Attachment device is equipped between first main body 1211 and second main body 1212；The attachment device includes being arranged on this
Screens 1241 on first main body, 1211 side and it is arranged on 1212 side of the second main body that screens 1241 is corresponding sets with this
The card bone 1242 put, in the present embodiment, the quantity of the screens 1241 can be two, be respectively distributed to 1211 phase of the first main body
To in two long sides of setting.Then accordingly, the quantity of the card bone is also two, and it is opposite to be separately positioned on the second main body 1212
In two long sides set.In some other embodiment, which may be provided on the side of the second main body 1212, should
Card bone 1242 may be provided in the first main body 1211.
For another example shown in Fig. 2, Fig. 4 and Fig. 5, in the present embodiment, between first main body 1211 and second main body 1212
It is additionally provided with the fixing device 125 for fixing first main body 1211 and second main body 1212.The fixing device includes being arranged on this
Card slot 1251 in first main body 1211 and the buckle 1252 being arranged in second main body 1212.By by the buckle 1252
Stick into the card slot 1251, it is ensured that first main body 1211 is fixed with second main body 1212.
The second group sensor is installed in the mounting bracket 10, is correspondingly arranged with the limit light groove 122, with formed with this
The second induction zone that one induction zone staggers.Specifically, the second group sensor be installed on second group of mounting hole in, and this second
The light of group sensor can be appeared by second group of mounting hole, due to limiting the limitation of light groove 122, the sensing angle of the first group of sensor
Sensing angle of the degree more than the second group sensor；And the monitoring area of first induction zone is more than the monitoring of second induction zone
Area.In the present embodiment, which can monitor the interior space, then the second induction zone institute monitoring range is confined to out
Entrance.
Further, which includes being separately positioned on the 3rd mounting hole 1231 and the 4th mounting hole
Identified in 1232 inlet whether someone disengaging the 3rd infrared sensor and the 4th infrared sensor.3rd infrared sensing
Device and the 4th infrared sensor can also be pyroelectric infrared sensors, and whether it can interpolate that human body disengaging at entrance
And the information for passing in and out human body is sent to control device.The transparent surface size of the optical lens of 3rd infrared sensor with this
The size of three mounting holes 1231 is of substantially equal；Then the section of the 3rd mounting hole 1231 is the printing opacity of the 3rd infrared sensor
Face, because limit light groove 122 limits, then actual transparent surface is less than the section of the 3rd mounting hole 1231.The light of 4th infrared sensor
Transparent surface size and the size of the 4th mounting hole 1232 for learning lens are of substantially equal；Then the section of the 4th mounting hole 1232 is
The transparent surface of 4th infrared sensor, because limit light groove 122 limits, then actual transparent surface is less than cutting for the 4th mounting hole 1232
Face.
By taking this is arranged on one existing room entrance there are formula control device as an example, there are the realization of formula control device for this
The method of intelligent control：When human body enters room, first, when human body reaches entrance, the 3rd infrared sensor and/or the 4th
Infrared sensor first receives infrared signal existing for human body, and sends the signal to control device；Secondly, when human body enters room
Between, the first infrared sensor and/or the second infrared sensor sense in space with the presence of human body again, then send infrared signal
To control device, control device judges that someone enters in space, and then control according to received two infrared signal sequencings
Indoor relevant device is opened.When human body withdraws from a room, first, when human body is gone on foot to entrance, first infrared sensor and/or
Second infrared sensor first receives human body presence signal, and infrared signal is sent to control device；Secondly, when human body arrives
Up at entrance, the 3rd infrared sensor and the 4th infrared sensor have received infrared signal existing for human body again, and
Infrared signal is sent to control device；Control device judges that someone leaves sky according to the sequencing of received infrared signal
Between, and then relevant device is closed in control room.
It should be understood that above example only expresses the preferred embodiment of the present invention, it describes more specific and detailed
Carefully, but the limitation to the scope of the claims of the present invention therefore can not be interpreted as；It should be pointed out that the common skill for this area
For art personnel, without departing from the inventive concept of the premise, above-mentioned technical characterstic can be freely combined, can also done
Go out several modifications and improvements, these belong to protection scope of the present invention；Therefore, it is all to be done with scope of the invention as claimed
