Specific embodiment
Referring to Fig. 1, the protective device of the anti-elevator door folder passenger of the present invention, including inductive component 10 and controller 20,
The inductive component 10 is arranged on gate frame or car front standing pillar, and the inductive component 10 connects with 20 signal of controller
It connects.
Specifically, it can combine refering to Fig. 1 and Fig. 2, it is saturating that the inductive component 10 includes infra red sensor 11, Fresnel
Mirror 12 and light filtering window 13.The Fresnel Lenses 12 is arranged at the infrared signal sending and receiving mouth of the infra red sensor 11,
The light filtering window 13 is located on the infra red sensor 11.
The inductive component 10 of the present embodiment is connect, and the sense group by cable 14 with 20 signal of controller
Part 10 is preferably arranged on by a mounting bracket 15 on gate frame or car front standing pillar.
The making material of infra red sensor 11 can be different, and the infra red sensor 11 of the present embodiment is preferred
Ground is made of lead zirconate titanate.The present embodiment makes very thin thin slice using lead zirconat-titanato material, each plate sheet it is opposite two
An electrode is respectively drawn in face, and an equivalent small capacitances, the as infra red sensor of embodiment are then formed at electrode both ends
11.When infra red sensor 11 does not detect the infrared signal that human body radiation goes out, in the both ends polarization of capacitance
On the contrary, the equal positive and negative charge of electricity, and the polarity of the two capacitances is phase anti-series, so positive and negative charge mutually supports
Disappear, no current in circuit, infra red sensor 11 is without output.When infra red sensor 11 detects that mobile human body gives off
Infrared signal when, positive and negative charge cannot cancel out each other, and have electric current, 11 output signal of infra red sensor in circuit.
Since the normal body temperature of human body is 36-37.5 DEG C, i.e. 309-310.5K, the wavelength of the infrared ray of radiation is λ m=
2989/ (309-310.5)=9.67-9.62um, the wherein a length of 9.65um of cardiac wave, just fall in infrared sensor infrared ray responsive
The center of the response wave length of element 11, infra red sensor 11 perceive the infrared signal of human body generation, and pass through cable 14
Infrared signal is transmitted to controller 20.
Please refer to Fig. 3 and Fig. 4, the spy that L is the detection range of infra red sensor 11, H is infra red sensor 11
Survey height, H=L × sin α.If without using Fresnel Lenses 12, the detection range L of infra red sensor 11 matches less than 2 meters
After upper Fresnel Lenses 12, the detection range L of infra red sensor 11 can be less than 2 meters or more 10 meters.
Light filtering window 13 can effectively allow the infrared ray of human body radiation to pass through, and prevent sunlight, light etc. visible to the maximum extent
Infrared ray in light passes through, to avoid causing interference as possible.
Referring to Fig. 5, the guard method of anti-elevator door folder passenger of the present invention a kind of, includes the following steps：
S1. specified shutdown stroke distances D and specified human perception number X are preset in controller 20, if actual human body perceives
Number is Y；
The specified shutdown stroke distances D and specified human perception number X of setting can be according to circumstances adjusted, it usually can be by X
Value is 3.
When independent safety edge door is protected, the last stroke of elevator shutdown in D values GB 7588；
When photoelectric protection+safety edge protection, light curtain protection+safety edge protection, the protection of pure light curtain, D values GB
The last stroke of elevator shutdown adds 300mm ± 50mm again in 7588；300mm ± 50mm is used to sense the sensing of photoelectricity, light curtain in itself
Blind area.
S2. the infra red sensor 11 of inductive component 10 detects infrared signal, and the infrared signal detected is sent
To controller,
If the infrared signal falls into specified shutdown stroke distances D, this infrared signal is included in actual human body by controller 20
Perceive number Y；
If infrared signal Bu Men areas do not fall within specified shutdown stroke distances D, controller 20 is by this infrared signal
It is not included in actual human body and perceives number Y；
If S3. Y ＜ X, controller 20 controls elevator door automatic door-closing；
If Y >=X, controller 20 controls elevator door automatic door opening to the limit and to keep
And prompting is closed the door manually, is manually pressed by door close button, elevator door is closed the door at a slow speed；
Elevator door completely closes, then Y resets.
Relative to the prior art, the protective device of anti-elevator door of the invention folder passenger is by setting inductive component and control
Device, the human infrared signal detected by controller record infra red sensor, controls the enabling or shutdown of elevator door, solves
Elevator door protection device in the prior art of having determined is filled in the last stroke of elevator shutdown or using the protection of infrared electronic product class door
It acts on the problem of vulnerable in the sense blind area region put, and elevator door is avoided to clamp or crush passenger.The anti-elevator door of the present invention
The guard method of folder passenger has many advantages, such as to be quick on the draw, non-blind area, anti-pinch effect are good.
Embodiment described above only expresses the several embodiments of the present invention, and description is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that those of ordinary skill in the art are come
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Range.
