Abstract
The utility model discloses an induction automatic door with the fast obstacle identifying function, comprising that the signal generated by an infrared probe is transmitted to the controlling motor of computer controller. A driving belt is driven by the motor, and is connected with a movable door through a lifting frame hung on the driving belt; a driving wheel is additionally provided with a photoimpact rotary detector. The photoimpact rotary detector is composed of a rotary toothed wheelarranged on the rotary shaft of the transmitting wheel, a light emitting diode and a phototriode. The utility model has the fast identifying function on the obstacle encountered by the automatic door, has simple structure, and can efficiently avoid the extrusion on the human body caused by the door.
Description
The utility model relates to the induction automatic door, relates in particular to the induction automatic door with quick obstacle recognition function.
Hotel, shop, bank street architecture thing gate, and hospital operating room, gates such as various sterile production workshop adopt the induction automatic door usually.It comprises that the signal that the infrared probe that is fixed on the doorframe produces passes to computer controller control motor, drag driving-belt by motor, again by hang on driving-belt suspension bracket with move the door link to each other, driving-belt joins with the drive that is fixed on the drive support, and drive is provided with turning cylinder, nut.Prior art existing problems: (1). the extruding problem.Pyroelectric infrared sensor has characteristics, and it just can produce signal when promptly human body moved, in case and human body is static, promptly the person who happens to be on hand for an errand is in its sensitive range A, the signal of probe also can disappear.At this moment, the controller misidentification is behaved and is left, and control gate is made closing movement.If the people is in the middle of the two fan doors, just can be squeezed.After the people is squeezed, motor rotation blockage, electric current can rise.Present automatic door knows to close the door by the conversion that detects this electric current just and is hampered, thereby reopens door.But this testing process is slower, often wants several seconds.Therefore all there is this problem in present induction door: promptly be between two fans and when motionless, can be subjected to the long period, the extruding of bigger power as the people.To children below six years old and pregnant woman, this extruding force usually makes people's astasia, or feels mild pain.
The purpose of this utility model provides a kind of extruded induction automatic door with quick obstacle recognition function of human body of avoiding.
The utility model is taked following measures in order to achieve the above object: have quick obstacle recognition function the induction automatic door it comprise that the signal that is produced by the infrared probe that is fixed on the doorframe passes to computer controller, the control motor, drag driving-belt by motor, again by hang on driving-belt suspension bracket with move the door link to each other, drive on driving-belt and the fixed conveyor wheel support joins, drive is provided with turning cylinder, nut, be provided with the photoimpact rotary detector at the drive place, it has the rotation toothed disc that is provided with on turning cylinder.Be located at the light that the light emitting diode that rotates toothed disc outer rim both sides sends and arrive phototriode through rotating the toothed disc inter-lobe clearance, the output pulse P that is obtained controls motor through computer controller, and the place is provided with protective casing at light emitting diode.
The utility model is simple in structure.The photoimpact rotary detector of being set up is made of light emitting diode, phototriode and rotation toothed disc.When toothed disc was rotated between two pipes, the light of luminous tube or quilt dish tooth blocked, or reach phototriode through the slit of tooth and between cog, thereby promptly produce a series of pulse signals at the phototriode place.Adopt the photoimpact rotary detector can avoid human body to be squeezed, in case door runs into the human body blocking, the umber of pulse of photodetector output reduces immediately, thereby in short time a few tens of milliseconds, people or object blocks are arranged immediately as can be known, controller is controlled the motor stall immediately, or counter-rotating, makes people or thing avoid extruding.
Describe in detail below in conjunction with accompanying drawing:
Fig. 1 is the induction automatic door lateral view with quick obstacle recognition function;
Fig. 2 is the induction automatic door structure schematic diagram with quick obstacle recognition function;
Fig. 3 is a photoimpact rotary detector structural representation;
Fig. 4 rotates the toothed disc structural representation.
Induction automatic door with quick obstacle recognition function is passed to computer controller 3 by the signal that the infrared probe 1 that is fixed on the doorframe 7 produces; control motor 2; drag driving-belt 4 by motor; again by hang on driving-belt suspension bracket 5 with move door and 6 link to each other; drive 15 on driving-belt and the fixed conveyor wheel support 18 joins; drive is provided with turning cylinder 16; nut 17; the drive place is provided with the photoimpact rotary detector; it has the rotation toothed disc 9 that is provided with on turning cylinder; be located at the light that the light emitting diode 11 that rotates toothed disc outer rim both sides sends and arrive phototriode 13 through rotating the toothed disc inter-lobe clearance; the output pulse P that is obtained controls motor through computer controller, is provided with protective casing 10 at the light emitting diode place.The photoimpact rotary detector can be to rotate toothed wheel and be located at the shape of a hoof photoelectric sensor that rotates the toothed wheel outer rim and constitutes rotating pulse generator and optical rotary encoder.
