Cabinet processed.
Further, the threshold value that described elevator control cabinet is preset includes first threshold and Second Threshold；
When the fracture of wire quantity in described pull rope designated length exceedes first threshold, described elevator control cabinet
Send pull rope and need the fault-signal of artificial repair and maintenance, but elevator still can be properly functioning；When described traction
When fracture of wire quantity in rope designated length exceedes Second Threshold, described elevator control cabinet report pull rope damages
Bad fault, elevator is out of service.
Further, described pull rope circuit wire detecting device be arranged on elevator traction sheave and directive wheel it
Between, described pull rope is through the probe within pull rope circuit wire detecting device.
The invention have the benefit that and automatically can examine conveniently by infrared imaging detection device
Survey the fracture of wire situation that appearance is coated with the pull rope of thermoplastic coating, and by detection device and electricity
The connection of ladder switch board, real time record pull rope fracture of wire quantity and corresponding circuit wire position, reduce
The repair and maintenance difficulty of elevator and cost of labor, repair and maintenance personnel can read the disconnected of pull rope as required
Silk quantity.In running process of elevator, elevator control cabinet can disconnected according to memorizer record in real time
Silk quantity, it is judged that the fracture of wire situation of pull rope is the need of carrying out artificial repair and maintenance detection or needs
More renew pull rope, and make and control operation accordingly, it is provided that the safety in utilization of pull rope,
Ensure elevator reliability service.

Fig. 2 is the scheme of installation of the elevator traction rope circuit wire detecting device of the embodiment of the present invention；
Fig. 3 is the elevator traction rope fracture of wire form of expression schematic diagram of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings and the present invention is described in further detail by specific embodiment.
As it is shown in figure 1, the control method of a kind of elevator traction rope fracture of wire detection, comprise the following steps:
S101. pull rope circuit wire detecting device detects the fracture of wire situation of pull rope in real time.
It should be noted that in this step, pull rope circuit wire detecting device uses infrared imaging inspection
Survey device, but infrared imaging detects the device that device simply can use, it is possible to use magnetic flux inspection
Survey device.Pull rope is generally circular, uses the structure of steel wire rope appearance coating thermoplastic coating,
Its fracture of wire form of expression is (as shown in Figure 3): when the tired bending of the steel wire rope 8 within pull rope
After impaired, part steel wire 7 there will be fracture of wire, under the frictional force effect of traction sheave, occurs disconnected
The steel wire 7 meeting Inner extrusion of silk, and poke thermoplastic coating 9, it is exposed to thermoplastic coating 9
Surface.The shape of cross section of infrared imaging detection device real time scan pull rope, detects whether it has
Fracture of wire situation.
S102. pull rope circuit wire detecting device detects that fracture of wire occurs in pull rope, sends fracture of wire letter in real time
Number give elevator control cabinet.
When fracture of wire occurs in the pull rope being coated with thermoplastic coating, its fracture of wire (steel wire) can be poked
Thermoplastic coating, changes pull rope shape of display on infrared imaging detection device, and then to electricity
Ladder switch board sends local flaw signal.
S103. elevator control cabinet reception local flaw signal, and record in memory: fracture of wire quantity, inspection
The survey time, the car location information that the detection time is corresponding.
After elevator control cabinet receives local flaw signal, its internal storage can record the fracture of wire of pull rope
The detection time that quantity is corresponding with often place's fracture of wire, meanwhile, elevator control cabinet, according to the detection time, is read
Take the car location information of the internal real time record of switch board, and write in memorizer, thus record leads
The accurate location of fracture of wire often located by messenger.
The positional information of car can be carried out by the rotary encoder through signals of elevator control cabinet real-time reception
Calculate gained, be a kind of position signalling that can read in real time.
S104. elevator control cabinet is according to the fracture of wire data of record in memorizer, automatically calculates each appointment
The fracture of wire quantity of length pull rope, and judge whether to exceed default threshold value, and control accordingly
Operation.
Pull rope fracture of wire quantity according to memorizer record and circuit wire position, elevator control cabinet can be according to
The hanging ratio of elevator, converses fracture of wire quantity total on each designated length pull rope, and sentences in real time
Whether disconnected its exceedes default threshold value.
The threshold value that elevator control cabinet is preset can be multiple value, if any first threshold 5 and Second Threshold
10。
If the total fracture of wire quantity on 1 meter of pull rope of described a certain designated length exceedes described default
First threshold 5, the most described elevator control cabinet sends pull rope and needs the fault-signal of artificial repair and maintenance, but electric
Ladder still can be properly functioning；
If the fracture of wire quantity on 1 meter of pull rope of described designated length exceedes described default Second Threshold
10, the most described elevator control cabinet report pull rope damage fault, elevator is out of service, wait to be replaced newly
Pull rope.
As in figure 2 it is shown, be the installation of the elevator traction rope circuit wire detecting device of the embodiment of the present invention
Schematic diagram.Circuit wire detecting device 3 is arranged between traction sheave 2 and directive wheel 6, pull rope 1 warp
Crossing the probe within circuit wire detecting device 3, circuit wire detecting device 3 is by holding wire 4 and elevator control
Cabinet 5 processed connects, can real-time Transmission pull rope local flaw signal to elevator control cabinet.
Above-described embodiment is used for illustrative purposes only, and not limitation of the present invention, relevant skill
The those of ordinary skill in art field, without departing from the spirit and scope of the present invention, also may be used
To make a variety of changes and modification, the technical scheme of the most all equivalents falls within scope of the invention,
The scope of patent protection of the present invention should be limited by each claim.
