The wear of the contact surface of the elevator drive rope wheel will reduce the friction coefficient between it and the rope, increase the frequency of the occurrence of slipping, cause safety problems such as the brake failing to immediately stop the car, and on the other hand, the excessive wear of the rope groove will also cause a large error between the actual rotation radius of the elevator drive rope wheel and its nominal value, thereby causing the elevator control performance (such as the level precision) to be reduced. Therefore, it is necessary to detect the wear of the elevator drive rope wheel, so as to take appropriate measures according to the wear condition of the elevator drive rope wheel.

However, the detection method of the system is relatively simple, mainly relying on the signal feedback of the sensor, and cannot realize the accurate analysis and evaluation of the wear condition of the steel wire rope wheel.

However, due to the existence of surface debris, the precision is unreliable. In addition, most of the existing detection devices cannot adapt to the complex shape of the steel wire rope wheel surface, and are easily disturbed by environmental light during the detection process, resulting in inaccurate detection results.

[0034] The application will be further described in conjunction with the drawings and examples. It can be understood that the specific examples described are only used to explain the related application, and are not limited to the application. In addition, it should be noted that only the parts related to the application are shown in the drawings for ease of description.
[0035] It should be noted that the examples in the present application and the features in the examples can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in conjunction with the examples.
[0036] Please refer to Figures 1-2 The present application provides the following technical solutions:
[0037] Specifically, it refers to a steel wire rope wheel monitoring line structure light three-dimensional measurement device, which comprises a laser emitter 1, an industrial camera 2, a measured rope wheel 3 and a modular support device. According to tests, the installation at an angle of 30° can more comprehensively capture distorted laser lines, and the smaller the included angle between the two, the smaller the distance between them, which can better adapt to narrow spaces. The laser and the camera are installed at an angle of 30°, without the need to disassemble the rope wheel, and the installation is convenient. Therefore, the laser emitter 1 and the industrial camera 2 are installed on the modular support device at an angle of 30°.
[0038] The data transmission end of the industrial camera 2 is connected with a signal output device, the signal output device is connected with a signal receiving device, the output end of the signal receiving device is connected with a processor, and the processor 3 is integrated with five software modules, namely, an image preprocessing module, a light strip center extraction module, a template matching and displacement calculation module, an intelligent early warning and life prediction module, and a data storage and management module.
[0039] The technical scheme comprises the following steps:
[0040] The line laser projected by the laser emitter 1 covers the rope groove section of the rope wheel 3. Due to the geometric shape and surface characteristics of the rope groove, the light strip will be distorted at the rope groove. After the transmission instruction is issued, the industrial camera 2 starts to collect the distorted light strip images in real time, and finally transmits them to the processor.
[0041] The working sequence of the five software modules in the processor is as follows:
[0042] The image preprocessing module performs Gaussian filtering on the original image to suppress noise in the image, and then performs morphological closing operation, first inflation and then corrosion, fills the light strip broken area, and makes the light strip image more complete and smooth. Finally, according to the image gray scale statistical characteristics, the adaptive threshold is calculated and dynamic threshold segmentation is performed to separate the light strip area from the background, providing a clear image basis for subsequent light strip center extraction.
[0043] The light strip center extraction module is to analyze the preprocessed image, calculate the gray center of each pixel point by using the improved gray center method combined with cubic spline interpolation, obtain the center coordinates of the light strip, and realize sub-pixel level (0.1 pixel) center positioning. For the broken part of the light strip caused by the rope groove shielding, 3-order B-spline basis function is used for fitting connection to ensure the integrity and continuity of the light strip center line, so as to accurately reflect the actual profile of the rope groove.
[0044] The template matching and displacement calculation module first extracts the profile of the rope groove by using the Canny edge detection algorithm, calculates the curvature of the profile points, and selects the curvature extreme points as the key feature points of the rope groove. Then, the improved pyramid search algorithm is used for template matching. The normalized Manhattan distance is calculated at the top layer of the pyramid to quickly exclude non-target areas for pre-screening. The affine transformation model is introduced at the bottom layer to optimize the matching result, and the matching speed and accuracy are improved. Finally, combined with the calibration parameters of the camera and the laser plane, the pixel displacement amount is converted into physical displacement amount to obtain the wear amount of the rope groove and the deflection amount of the wheel body.
[0045] The intelligent early warning and life prediction module monitors the calculated rope groove wear and deflection in real time. When the wear exceeds the threshold value specified in GB / T31821-2015 standard or the deflection is greater than 0.1mm, the cloud alarm is triggered immediately, and the operation and maintenance personnel are reminded to take timely measures through local interface pop-up window, SMS notification and other ways. At the same time, the system stores the historical monitoring data in the InfluxDB time series database, generates the wear trend curve, deflection heat map and statistical summary by using Grafana, analyzes the wear data of the last 30 days by using the LSTM life prediction model, and outputs the remaining useful life (RUL) of the steel wire rope wheel. The prediction error is controlled to provide a scientific basis for equipment maintenance and replacement plan.
[0046] The data storage and management module stores and backs up the monitoring data, image data, alarm records and other information regularly, provides data query, statistics and report generation functions, and facilitates users to analyze and manage historical data, thereby providing data support for long-term maintenance and management of equipment.
[0047] The measuring device realizes real-time monitoring and early warning of the rope groove wear and the wheel body deflection through the deep integration of line structured light three-dimensional measurement, adaptive image processing algorithm and cloud data analysis, and non-contact detection technology to monitor the rope groove wear and the wheel body deflection of the steel wire rope wheel in real time, thereby solving the problems of low measurement accuracy and poor efficiency of traditional manual plug gauge and existing installation position and environmental interference.

The embedded plate 95 is arranged between the inner wall of the contraction cavity 92 and the outer surface of the limiting rod 93. A second tension spring 96 is movably arranged on the outer surface of the limiting rod 93. The tension strength of the second tension spring 96 is greater than the tension strength of the spring 812.
[0061] When the bolt 91 is fixed to the mounting shell 61, the limiting rod 93 is inserted into the limiting groove 94, so as to limit the tooth plate 810. When the gear 89 meshes with the tooth plate 810 to drive the tooth plate 810 to displace, the circular arc surface of the limiting groove 94 can extrude the limiting rod 93, so that the limiting rod 93 displaces to the side close to the bolt 91. At the same time, the second tension spring 96 is stretched under the force. When the tooth plate 810 stops displacing, the limiting rod 93 is displaced into the limiting groove 94 again under the pulling of the second tension spring 96. Since the tension strength of the second tension spring 96 is greater than the tension strength of the spring 812, when the spring 812 is stretched or extruded, the spring 812 cannot pull or push the piston 811 to displace, so that the laser emitter 1 or the industrial camera 2 cannot return after the angle adjustment, thereby ensuring the stability of the laser emitter 1 or the industrial camera 2 after the angle adjustment.
[0062] The support assembly 5 comprises a support column 51 which is detachably arranged on the lower surface of the mounting plate 4. The lower surface of the support column 51 is hingedly provided with a plurality of support legs 52. The bottom of the support column 51 is provided with an adjusting rod 54. The lower end of the adjusting rod 54 is rotatably connected with a bottom plate 55. The inner side surface of the support leg 52 and the outer surface of the bottom plate 55 are hingedly provided with a first rotating plate 56. The support column 51 is provided with an embedded cavity 53. The upper end of the adjusting rod 54 is provided with screw teeth. The upper end of the adjusting rod 54 is screwed into the embedded cavity 53.
[0063] In use, the adjusting rod 54 is twisted to displace upward under the transmission of the screw teeth. At the same time, the bottom plate 55 moves upward synchronously with the adjusting rod 54. At this time, the bottom plate 55 can form a pulling force on the first rotating plate 56. The first rotating plate 56 synchronously pulls the support leg 52 to displace inward, so that the support leg 52 is contracted. When the adjusting rod 54 is displaced downward, the bottom plate 55 forms a pushing force on the first rotating plate 56. The first rotating plate 56 synchronously pushes the support leg 52 to rotate outward, so that the support leg 52 can form a stable support effect. Therefore, the measuring device can be placed on the ground close to the rope pulley 3.
[0064] Further, the outer surface of the support column 51 is provided with a plurality of pressing plates 59, the surface of the support column 51 towards the pressing plates 59 is provided with sliding grooves 510, the inner side of the pressing plates 59 is provided with sliding rods 58, the other end of the sliding rods 58 extends into the sliding grooves 510 and slides in the sliding grooves 510, the upper end of the adjusting rod 54 is rotationally connected with a pressing plate 57, the outer surface of the support column 51 close to the pressing plates 59 is provided with extension grooves 511 which are in communication with the built-in cavity 53, the outer surface of the pressing plate 57 is hingedly connected with a plurality of second rotating plates 512, the other side of the second rotating plates 512 extends out of the outer side of the support column 51 through the extension grooves 511 and is hingedly connected with the pressing plates 59.
[0065] In use, when the bottom of the rope wheel 3 is not a channel for the downward extending steel wire rope, the adjusting rod 54 is controlled to displace upward, the pressing plate 57 is synchronously displaced upward with the adjusting rod 54, the pressing plate 57 will form a pushing force on the second rotating plates 512, at this time, the second rotating plates 512 push the pressing plates 59 to displace away from the support column 51, at the same time, the sliding rods 58 slide in the sliding grooves 510, so that the pressing plates 59 can press the inner wall of the channel, thus the measuring device can be installed in the channel at the bottom of the rope wheel 3, when the adjusting rod 54 is controlled to displace downward, the pressing plates 59 can be controlled to displace close to the support column 51, thus the measuring device can be taken out of the channel, by the above structure, the pressing plates 59 can be controlled to displace close to the support column 51 on the ground, the support assembly 5 is convenient to take, and when the measuring device is placed in the channel, the support legs 52 are controlled to displace inward, thus the support assembly 5 is not blocked, the use effect of the support assembly 5 is improved.
