Background
The elevator steel wire rope group is an important component which is used for connecting the elevator car and the counterweight and has the functions of traction and dragging, and plays an important role in the safe operation of the elevator. Because the steel wire ropes are gradually extended after being stressed and the extension amount of each steel wire rope is inconsistent, the tension borne by the steel wire ropes is uneven and the friction of the traction wheel grooves is inconsistent. If the problems are not timely processed, the steel wire rope group is damaged, the traction sheave is irregularly abraded, the elevator runs in a shaking mode, the elevator riding comfort is affected, the service life of relevant parts of the elevator is shortened, even the steel wire rope is separated from the groove in serious conditions, and serious potential safety hazards exist.
In the existing method for detecting and adjusting the tension borne by the steel wire ropes, after the tension of each steel wire rope is measured one by a spring scale in a well, a nut of an adjusting device at the end part of each steel wire rope is adjusted to tension or loosen a certain steel wire rope, so that the tension borne by all the steel wire ropes is consistent.
In 6 days 4 and 6 months 2020, the State market administration issues an opinion on further improvement of the maintenance mode of the elevator and adjustment of the trial operation of the elevator inspection and detection mode (Special No. 2020/56), and its attachment 3, requirement for the relaxation protection of A5.1.3 suspension devices in Elevator detection rules (trial implementation), "for an elevator in which the car is suspended on two suspension devices, the electrical safety device should be operated when one of the suspension devices is abnormally extended relatively". This electrical safety device can only move when the uneven atress of wire rope group reaches certain degree, and can lead to the elevator accident to stop the ladder and the accident of trapping after the action, does not possess early warning function in advance. The national institute of famous supervision is specially proposed in No. 2020 to 56: the method comprises the steps of ' popularizing ' the Internet of things and maintaining ', encouraging the popularization of the elevator to install a remote monitoring system based on the Internet of things, and adopting targeted offline field maintenance and maintenance by a maintenance unit according to real-time online inspection and monitoring maintenance conditions, so that the scientificity and effectiveness of maintenance are improved, and the safe operation of the elevator is guaranteed to the greatest extent. The utility model provides a this problem, send the early warning in advance when the distribution of wire rope group load changes, remind the dimension guarantor personnel in time to maintain to prevent the elevator because of the electrical safety device action bring to rest.

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.
As shown in fig. 1 and fig. 2, this embodiment provides an elevator wire rope stress state remote monitoring and early warning device, including video acquisition module, data processing module and the data transmission module that electricity is connected in proper order, and video acquisition module, data processing module and data transmission module install in same casing to form all-in-one 1. Because the machine room of the elevator is generally positioned at the top of the hoistway, the bearing beam 2, the traction sheave and the like are arranged in the machine room, and each steel wire rope 3 can be wound on the traction sheave of the machine room. The equipment adopts an integrated design, integrates three modules in the same shell to form a whole, and is fixed on the bearing beam 2 through the fixing device 5. The fixing device 5 may be a bolt fitted mounting plate or the like. Wherein, video acquisition module's camera is just to being located all wire rope group 3 of computer lab, gathers one of them side that the end is located two outsides of wire rope group 3 promptly, and the elevator is at the operation in-process, and wire rope group 3 all can be through gathering the dead ahead of end.
When the lift car of the elevator stops at each floor, flat layer marks are horizontally painted on the steel wire rope group opposite to the camera of the video acquisition module, the upper edge and the lower edge of the flat layer mark on each steel wire rope are horizontally aligned, and the flat layer mark lines on all the steel wire ropes are painted by white paint. The data processing module is used for comparing the flat layer marking image shot by the video acquisition module with the standard flat layer marking image stored by the data processing module and analyzing a jitter image when the steel wire rope group moves; and recognizing the conditions of uneven stress, abnormal relative elongation and groove shedding of the steel wire rope group, and sending the early warning information to the terminal equipment through the data transmission module. For easier viewing of the comparison results, standard flat layer markings are placed on all wire rope groups at the same place. The length of the mark on each steel wire rope is equal, and the upper edge and the lower edge are on the same horizontal line. When one or more steel wire ropes are subjected to uneven tension or abnormal relative elongation, the flat layer marks on partial steel wire ropes move relatively, so that straight lines formed by the upper edges and the lower edges of all the flat layer marks are staggered, comparison results are judged more easily, and judgment accuracy is improved.

as shown in fig. 3, the data processing module stores standard images of the flat marks such that the tension applied to each wire rope 3 is the same under normal conditions, and the top and bottom edges of all the flat marks in each image of the flat marks are horizontally aligned. If one or more steel wire ropes 3 are subjected to uneven tension or groove-disengaging faults, after the car stops at any landing, the flat-layer marked image shot by the video acquisition module is compared with the standard flat-layer marked image through the data processing module, and if the comparison result is consistent, the comparison result is normal. On the contrary, the upper and lower edges of the flat layer marks 4 on part of the steel wire rope 3 will move relatively, so that the upper and lower edges of all the flat layer marks 4 are dislocated, and the comparison result is abnormal. The shaking amplitude of each steel wire rope shot by the video acquisition module can reflect the load distribution state among the steel wire ropes, the shaking amplitude is relatively consistent and normal, and the shaking amplitude deviation value exceeds a certain range and is abnormal. After the data processing module identifies the abnormal stress state of the steel wire rope group, early warning information is generated and sent to the terminal equipment through the data transmission module.
