Abstract
The invention discloses an anti-pinch control method of an elevator door. According to the method, an obstacle detection system combined by an infrared detection module and a microwave detection module detects an obstacle in an elevator door closing process, so that a detection accuracy rate can be effectively increased and a pinch accident of the elevator door can be avoided.
Description
Technical field
The present invention relates to elevator door field, particularly relate to the elevator door control method of a kind of anti-pinch people.
Background technology
People to the use of elevator today more and more frequently, the safety of elevator especially elevator door has become social question of common concern.In daily life, elevator accident happens occasionally, and the news of relevant elevator door folder people is also usually reported in media.Therefore, ensureing the safe and reliable of elevator door, is society problem merited attention.In prior art, infrared detection technique is often adopted to carry out obstacle detection at closing time to elevator.Only adopt the detection accuracy rate of single detective technology not high, easily produce alert and false dismissal phenomenon by mistake.
Summary of the invention
The object of this invention is to provide that a kind of to detect accuracy rate high, the elevator door control method of more safe and reliable anti-pinch people.
For reaching this object, the present invention by the following technical solutions:
An anti-pinch people's elevator door control method, operates according to following steps:
S1: elevator door stops at certain layer;
S2: elevator door is opened;
S3: elevator door leaves to maximum rear maintenance 2 seconds;
S4: elevator door starts to cut out;
S5: carry out obstacle detection, if detect obstacle, gets back to S3 step;
S6: if do not detect obstacle, elevator door cuts out.
Preferably, described step S5 adopts detection system for obstacle to carry out obstacle detection, and detection system for obstacle comprises infrared detection module, microwave sounding module, power supply and microprocessor.
Compared to the prior art, beneficial effect of the present invention is: two kinds of Detection Techniques be combined, compensate for the defect of single detective technology, can effectively avoid occurring elevator door folder people accident.
Accompanying drawing explanation
Fig. 1 is diagram of circuit of the present invention;
Fig. 2 is detection system for obstacle block diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, further illustrate technical scheme of the present invention by detailed description of the invention.
See Fig. 1, the elevator door control method of anti-pinch people of the present invention operates according to following steps:
S1: elevator door stops at certain layer;
S2: elevator door is opened;
S3: elevator door leaves to maximum rear maintenance 2 seconds;
S4: elevator door starts to cut out;
S5: carry out obstacle detection, if detect obstacle, gets back to S3 step;
S6: if do not detect obstacle, elevator door cuts out.
Preferably, described step S5 adopts detection system for obstacle to carry out obstacle detection, and detection system for obstacle comprises infrared detection module, microwave sounding module, power supply and microprocessor.
