Abstract
The invention discloses a method for automatically detecting potential safety hazards of a hoisting rope of an elevator. The method is characterized in that the condition of burrs on the hoisting rope is obtained by means of detecting a projected image of the hoisting rope in a light source, so that potential safety hazards due to breakage of the hoisting rope of the elevator are judged. By the aid of the method, whether the hoisting rope of the elevator has potential safety hazards or not can be detected, accordingly, the hoisting rope can be timely replaced conveniently, and safety of the elevator is improved.
Description
Technical field
The present invention relates to a kind of elevator rope potential safety hazard automatic testing method and device, belong to elevator safety technical field.
Background technology
Elevator rope is used wire rope conventionally, and it is widely used in elevator hoistways, and its state directly has influence on the safe operation of elevator.Because hoist ropes work is always in tightening the state of friction with elevator rope pulley, therefore inevitably will there is the hidden danger of fracture.Before hoist ropes fracture, conventionally there will be burr phenomena in various degree.If the burr situation of hoist ropes, the security that just can learn hoist ropes detected.
Summary of the invention
The object of the invention is: a kind of elevator rope potential safety hazard automatic testing method and device are provided.Whether the hoist ropes that it can detect elevator there is potential safety hazard, to change in time hoist ropes, hoisting elevator security.
Object of the present invention can realize by following technical proposal: a kind of elevator rope potential safety hazard automatic testing method, be characterized in: by detecting hoist ropes, at the projected image under light source, draw the burr situation on hoist ropes, thereby judge the fracture potential safety hazard of elevator rope.
In above-mentioned elevator rope potential safety hazard automatic testing method, utilize LASER Light Source to irradiate hoist ropes, after hoist ropes, use video camera to obtain the hatching pattern of hoist ropes, burr on hoist ropes can produce diffraction pattern, the hoist ropes shade that video camera is obtained is greater than the shade while there is no burr, thereby judges the fracture potential safety hazard of elevator rope.
In aforesaid elevator rope potential safety hazard automatic testing method, on the pattern that the diffraction pattern that described burr produces obtains by statistics video camera, the gray-scale value of each pixel draws, when the gray-scale value summation drawing is greater than threshold value, judge that the burr situation of hoist ropes exists fracture potential safety hazard to hoist ropes.Therefore diffraction pattern makes shadow region area obviously be greater than the simple view field's area of burr, gray-scale value summation detected when larger, can automatic decision go out to be that diffraction due to burr causes.
In aforesaid elevator rope potential safety hazard automatic testing method, translucent paper film is set before camera lens, make shade imaging on paper film, video camera obtains the hatching pattern on paper film, paper film filters light, thereby the hatching pattern contrast that video camera gets improves, avoided the impact of the loose look of laser on the gray-scale value of each pixel on statistics pattern.
Realize a kind of elevator rope potential safety hazard automatic detection device of said method, be characterized in: comprise that emergent light direction is over against the generating laser of hoist ropes, the rear of hoist ropes is provided with video camera, and generating laser, hoist ropes and video camera are successively point-blank; Video camera is connected with processor, and processor is connected with output device.
In aforesaid elevator rope potential safety hazard automatic detection device, between described hoist ropes and video camera, be provided with translucent paper film.
In aforesaid elevator rope potential safety hazard automatic detection device, described output device is display device or acoustic-optic alarm.
Compared with prior art, the burr that utilization of the present invention is thinner can produce diffraction phenomena under light source irradiates, and the diffraction pattern that diffraction produces just can become the indicator diagram that hoist ropes produces burr; Again in conjunction with the statistics of gray-scale value, just can draw whether jagged, and then the fracture potential safety hazard of judgement elevator rope.
Accompanying drawing explanation
Fig. 1 is the structural representation of apparatus of the present invention.
Mark in accompanying drawing: 1-hoist ropes, 2-generating laser, 3-video camera, 4-processor, 5-output device, 6-paper film.
Embodiment
Below in conjunction with embodiment, the present invention is further illustrated, but not as the foundation to the present invention's restriction.
Elevator rope potential safety hazard automatic testing method draws the burr situation on hoist ropes by detecting hoist ropes at the projected image under light source, thereby judges the fracture potential safety hazard of elevator rope.Utilize LASER Light Source to irradiate hoist ropes, after hoist ropes, use video camera to obtain the hatching pattern of hoist ropes, burr on hoist ropes can produce diffraction pattern, and the hoist ropes shade that video camera is obtained is greater than the shade while there is no burr, thereby judges the fracture potential safety hazard of elevator rope.On the pattern that the diffraction pattern that described burr produces obtains by statistics video camera, the gray-scale value of each pixel draws, when the gray-scale value summation drawing is greater than threshold value, judges that the burr situation of hoist ropes exists fracture potential safety hazard to hoist ropes.Translucent paper film is set before camera lens, make shade imaging on paper film, video camera obtains the hatching pattern on paper film, paper film filters light, thereby the hatching pattern contrast that video camera gets improves, avoided the impact of the loose look of laser on the gray-scale value of each pixel on statistics pattern.
An elevator rope potential safety hazard automatic detection device, as shown in Figure 1, comprises that emergent light direction is over against the generating laser 2 of hoist ropes 1, and the rear of hoist ropes 1 is provided with video camera 3, and generating laser 2, hoist ropes 1 and video camera 3 are successively point-blank; Video camera 3 is connected with processor 4, and processor 4 is connected with output device 5.Between described hoist ropes 1 and video camera 3, be provided with translucent paper film 6.Described output device 5 is display device or acoustic-optic alarm.
