Abstract
The invention discloses a kind of methods by foreign matter on current detecting elevator car door sill and hall door track.The electric current I of the door machine when the current sampling device in car door machine acquires elevator open and close door is set；The signal of acquisition is handled by the shaping modulate circuit of waveform, and digital signal is converted analog signals by analog-digital converter；The current I signal of time domain and frequency domain when being worked using digital signal extraction door machine；Various common operating modes are matched by time domain and the relevant information of frequency domain.The present invention is matched by detecting electric current I values in real time, by electric current I values with the pattern of setting, obtains on elevator car door sill and hall door track whether there is foreign matter, if so, obtaining loading level caused by current foreign matter, this method is simple and efficient reliable.
Description
Technical field：
The invention belongs to elevator door-motor detection technique field, more particularly to it is a kind of by current detecting elevator car door sill and
The method of foreign matter on hall door track.
Background technology：
Elevator faults, which have 80% or so, to be happened on door system, wherein it is exactly because in elevator car door to have prodigious ratio
Foreign matter has been accumulated on sill and the track of hall door.When being mixed into many sundries, such as cigarette butt, soil in the gate sill of compartment, hall door
Occur the foreign matters such as carbon deposit or dust on track, these easily cause elevator door cannot it is normally-open or close, sometimes can also close
People causes very bad social influence.
It is also very simple and clear although the reason of causing is very intuitive, to go directly to detect with relevant technology, by elevator
The limitation of physical space itself, special structure and cost, temporarily not yet or do not find also economic, practical, reliable and stable
Technology detects the foreign matter on compartment gate sill and hall door track.
Being disclosed in the information of the background technology part, it is only intended to increase understanding of the overall background of the invention, without answering
It has been the prior art well known to persons skilled in the art when being considered as recognizing or imply that the information is constituted in any form.
Invention content：
The purpose of the present invention is to provide a kind of sides by foreign matter on current detecting elevator car door sill and hall door track
Method solves the problems, such as long-term existence and cannot solve always to breach industry bottleneck.
To achieve the above object, the present invention provides one kind pass through it is different on current detecting elevator car door sill and hall door track
The method of object, step are：
(1) the electric current I of the door machine when the current sampling device in car door machine acquires elevator open and close door is set；
(2) signal of acquisition is handled by the shaping modulate circuit of waveform, and will be simulated by analog-digital converter
Signal is converted to digital signal；
(3) current I signal of time domain and frequency domain when digital signal extraction door machine being utilized to work；Pass through time domain and frequency domain
Relevant information matches operating mode, obtains on elevator car door sill and hall door track whether to have foreign matter.
Preferably, in technical solution, the operating mode in step (3) includes foreign pattern, have light load foreign matter pattern,
Middle load foreign matter pattern, heavy duty foreign matter pattern.
Compared with prior art, the present invention has the advantages that：
By detecting the abnormal current of motor, to realize the indirect detection to foreign matter, the object by elevator itself is solved
The problem of limitations such as reason space, structure and cost can not be directly detected.
Description of the drawings：
Fig. 1 is method flow schematic diagram of the present invention by foreign matter on current detecting elevator car door sill and hall door track.
Specific implementation mode：
The specific implementation mode of the present invention is described in detail below, it is to be understood that protection scope of the present invention is not
It is restricted by specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " comprising " or its change
It changes such as "comprising" or " including " etc. and will be understood to comprise stated element or component, and do not exclude other members
Part or other component parts.
As shown in Figure 1, a kind of method by foreign matter on current detecting elevator car door sill and hall door track, step
For：
(1) the electric current I of the door machine when the current sampling device in car door machine acquires elevator open and close door is set；
(2) signal of acquisition is handled by the shaping modulate circuit of waveform, and will be simulated by analog-digital converter
Signal is converted to digital signal；
(3) current I signal of time domain and frequency domain when digital signal extraction door machine being utilized to work；Pass through time domain and frequency domain
Relevant information come match foreign pattern, have in light load foreign matter pattern, middle load foreign matter pattern, heavy duty foreign matter pattern one
Kind, obtain on elevator car door sill and hall door track whether there is foreign matter.
The description of the aforementioned specific exemplary embodiment to the present invention is in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to the above instruction, can much be changed
And variation.The purpose of selecting and describing the exemplary embodiment is that explaining the specific principle of the present invention and its actually answering
With so that those skilled in the art can realize and utilize the present invention a variety of different exemplary implementation schemes and
Various chooses and changes.The scope of the present invention is intended to be limited by claims and its equivalents.
Claims (2)
1. a kind of method by foreign matter on current detecting elevator car door sill and hall door track, step are：
