Abstract
The present invention relates to a kind of novel 3D light curtain structure, belong to elevator safety field.It includes gate, it is arranged on the correlation photoelectric sensor of gate side, it is arranged on the controller within gate and the link gear with controller, also include microwave sensor, microwave emitter it is additionally provided with on microwave sensor, microwave sensor is arranged on side door placement of foot on gate, and microwave remote sensor is connected with controller.After personnel enter into the induction range of microwave sensor, microwave remote sensor will be transmitted signal and be terminated, if do not left in personnel 3s by control linkage to controller, controller, or enter the coverage of correlation photoelectric sensor, then controller controls gate unlatching.Usefulness of the present invention is: add the scope of detection, adds the safety of light curtain, just can detect personnel in door zone position.Add the response time of a machine, can detect whether district of going out has people in advance, reduce the risk that boarding personnel are clamped by gate.
Description
Technical field:
The present invention relates to a kind of novel 3D light curtain structure, belong to elevator safety field.
Background technology:
Elevator light curtain is a kind of light wire type safety protector of elevator door, is scanned sedan-chair the most continuously by infrared emission tube
Door region, forms an intensive infrared ray protection light curtain.When any of which Ray Of Light is blocked, control system is the most defeated
Going out enabling signal, gate i.e. phase down also inverts unlatching, until elevator door can after passenger or obstacle leave warning region
Normal switching-off, thus reach safeguard protection purpose, so can avoid the generation of elevator folder people's accident.
The light curtain that elevator cage door uses now is all conventional correlation light curtain, and its light curtain resolution used is low, when gate exists
When closing entrance under door state, door machine fortune state response still has, when not coming, the probability crushed by gate.
Summary of the invention:
For above technical problem, the present invention relates to a kind of novel 3D light curtain structure, including gate, be arranged on the right of gate side
Penetrating photoelectric sensor, be connected with correlation electric transducer is arranged on the controller within gate and is connected for controlling with controller
The link gear of gate switch action, it is characterised in that: also include microwave sensor, microwave sensor is additionally provided with Microwave emission
Device, microwave sensor is arranged on side door placement of foot on gate, and microwave remote sensor is connected with controller.
In order to expand the induction range of microwave sensor and improve the inductive effects of microwave sensor, further, microwave
Downward-sloping relative to gate 30 °～60 ° of antenna.
In order to improve the recognition speed to personnel, further, microwave sensor is reflection-type microwave remote sensor.
After personnel enter into the induction range of microwave sensor, microwave remote sensor will transmit signal to controller, control
Device terminates by controlling linkage, if do not left in personnel 3s, or the coverage of entrance correlation photoelectric sensor,
Then controller controls gate unlatching.
Compared with prior art, usefulness of the present invention is: add the scope of detection, adds the safety of light curtain
Property, just can detect personnel in door zone position.Add the response time of a machine, can detect whether district of going out has in advance
People, reduces the risk that boarding personnel are clamped by gate.
Accompanying drawing illustrates:
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is 3D light curtain structural representation；
Fig. 2 is sensor mounting location schematic diagram；
Fig. 3 is microwave remote sensor detection range schematic diagram.
In figure: 1, microwave sensor；2, correlation photoelectric sensor；3, gate；4, controller；5, link gear.
Detailed description of the invention:
One novel 3D light curtain structure as shown in Figure 1, Figure 2 and Figure 3, including gate 3, is arranged on the correlation photoelectricity of gate side
Induction apparatus 2, be connected with correlation electric transducer 2 is arranged on the controller 4 within gate 3 and is connected for controlling with controller 4
The link gear 5 of gate switch action, it is characterised in that: also include microwave sensor 1, microwave sensor 1 is additionally provided with microwave
Agitator 7 and microwave antenna 8, microwave sensor 1 is arranged on side door placement of foot on gate 3, microwave remote sensor 1 and controller 4 phase
Even.
Whenever Elevator landing, microwave oscillator 7 works and launches microwave by microwave antenna 8, arrives elevator doorway when there being people
Time, microwave reflection goes back, and microwave sensor 1 will detect, controller 4 will control link gear 5 and interrupt the cut out of gate 3
Action, may turn on gate 3 if stayed on, and is possible not only to prevent erroneous judgement, it is also possible to control the action of gate 3 in advance, anti-
Only people is crushed, if correlation photoelectric sensor 2 has people in region being detected, will directly be turned by link gear 5 closing motion
For breakdown action, improve the security performance of light curtain structure further.
It is emphasized that: be the most only presently preferred embodiments of the present invention, not the present invention is made any in form
Restriction, any simple modification, equivalent variations and the modification that above example is made by every technical spirit according to the present invention,
All still fall within the range of technical solution of the present invention.
