A kind of door body safety monitoring device
Technical field:
The present invention relates to stream of people's safety monitoring technology field, more specifically to a kind of door body safety monitoring device.
Background technology:
In order to monitor the amount of flow for the people for passing in and out doorframe, to convenient and safe management and stream of people's management, present mode one
As be to be irradiated by fixed infrared remote receiver and infrared transmitter, often pass through a people and count, but its position is solid
Surely it can not be adjusted so that it can not count the disengaging human body of different height, and effect is limited.
Invention content:
The purpose of the present invention is overcoming the deficiencies of the prior art and provide a kind of door body safety monitoring device, the infrared of it connects
Up and down adjustment can be synchronized by receiving device and infrared transmitter, be counted so as to the people to different height, be met not
Same statistical requirements.
The present invention solve the technical problem scheme be:
A kind of door body safety monitoring device, including doorframe, the top of the top plate of doorframe have a upper placed cavity, two of doorframe
The rear portion of side plate has side placed cavity, and vertical adjusting screw rod is equipped in the placed cavity of side, and the both ends of vertical adjusting screw rod are hinged
In two support plates, two support plates are fixed on the upper and lower part wall surface of the side plate of doorframe, and adjusting block is screwed onto vertically
In adjusting screw rod, it is fixed with infrared transmitter on an adjusting block, infrared remote receiver, infrared hair are fixed on another adjusting block
Double shafts are equipped in the vertical chute that emitter and infrared remote receiver sleeve have on the side plate of corresponding doorframe, in upper placed cavity
Two shafts of motor, double output shaft electric machines are equipped with output bevel gear wheel, and the top of two vertical adjusting screw rods passes through the branch on top
Fagging simultaneously stretches into placed cavity, and the tops of two vertical adjusting screw rods is fixed with drive bevel gear, output bevel gear wheel and corresponding
Drive bevel gear is meshed.
Wifi wireless modules are fixed in control mainboard in the infrared remote receiver, wifi wireless modules pass through no circuit
It is connected with local area network by device and the data sensed is conveyed to the control being connected with local area network by wireless router
End processed.
The both sides of the top plate of the doorframe are hinged with intermediate rotary shaft, and one end of intermediate rotary shaft passes through shaft coupling and double shaft electricity
The corresponding shaft of machine is connected, and the other end of intermediate rotary shaft is fixed with output bevel gear wheel.
The present invention protrusion effect be:
Compared with prior art, its infrared remote receiver and infrared transmitter can synchronize up and down adjustment, so as to
It is counted with the people to different height, meets different statistical requirements.
Description of the drawings:
Fig. 1 is the structural schematic diagram of the present invention;
Fig. 2 is the control principle of infrared remote receiver.
Specific implementation mode:
Embodiment is shown in as shown in Figure 1 to Figure 2, a kind of door body safety monitoring device, including doorframe 10, the top plate of doorframe 10
Top there is upper placed cavity 1, the rear portions of two side plates of doorframe 10 to have side placed cavity 2, are equipped in side placed cavity 2 perpendicular
Straight adjusting screw rod 3, the both ends of vertical adjusting screw rod 3 are hinged in two support plates 4, and two support plates 4 are fixed on doorframe 10
On the upper and lower part wall surface of side plate, adjusting block 5 is screwed onto in vertical adjusting screw rod 3, and infrared hair is fixed on an adjusting block 5
Emitter 6 is fixed with infrared remote receiver 7 on another adjusting block 5, and infrared transmitter 6 and 7 sleeve of infrared remote receiver are in corresponding door
Double output shaft electric machines 8 are equipped in the vertical chute 12 having on the side plate of frame 10, in upper placed cavity 1, two of double output shaft electric machines 8 turn
Axis is equipped with output bevel gear wheel 81, and the top of two vertical adjusting screw rods 3 passes through the support plate 4 on top and stretches into placed cavity 1,
The top of two vertical adjusting screw rods 3 is fixed with drive bevel gear 31,31 phase of output bevel gear wheel 81 and corresponding drive bevel gear
Engagement.
Further, wifi wireless modules are fixed in the control mainboard in the infrared remote receiver 7, wifi is wireless mould
Block is connected with local area network by wireless router 20 and the data sensed is conveyed to through wireless router 20 and office
The control terminal 30 that domain network is connected.
Further, the both sides of the top plate of the doorframe 10 are hinged with intermediate rotary shaft 11, and one end of intermediate rotary shaft 11 is logical
It crosses shaft coupling with the corresponding shaft of double output shaft electric machines 8 to be connected, the other end of intermediate rotary shaft 11 is fixed with output bevel gear wheel 81.
Operation principle:It is run by double output shaft electric machines 8, the rotation of output bevel gear wheel 81 may be implemented, to drive transmission to bore
Gear 31 rotates, and the synchronizing moving up and down of two adjusting blocks 5 thus may be implemented, and realizes and enters doorframe 10 to different height
People count, testing principle be infrared transmitter 6 by infrared emitting to infrared remote receiver 7, when 7 nothing of infrared remote receiver
I.e. explanation has personage to pass by when method receives infrared ray, i.e., signal is delivered to local area network by wifi wireless modules and will counted
Statistics is realized by the control terminal 30 that wireless router 20 is connected with local area network according to being conveyed to, and control terminal 30 can electricity
Brain, mobile phone etc., it is very convenient.
Finally, embodiment of above is merely to illustrate the present invention, and not limitation of the present invention, related technical field
Those of ordinary skill can also make a variety of changes and modification without departing from the spirit and scope of the present invention, therefore
All equivalent technical solutions also belong to scope of the invention, and scope of patent protection of the invention should be defined by the claims.
