The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0029] In one embodiment, if Figure 1 As shown, the traction rope detection device 100 includes an electromagnetic radiation emission module 101 and an electromagnetic radiation detection module 102 which are arranged opposite to each other.

[0030] The electromagnetic radiation transmitting module 101 is used to transmit electromagnetic radiation and pass the electromagnetic radiation through the traction rope. The electromagnetic radiation detection module 102 is used to detect the electromagnetic radiation emitted by the electromagnetic radiation transmitting module 101 and send a detection signal. The traction rope is arranged between the electromagnetic radiation transmitting module 101 and the electromagnetic radiation detection module 102. The traction rope is used to hoist the elevator and includes steel wire ropes, steel belts and other types. The electromagnetic radiation transmitting module 101 and the electromagnetic radiation detection module 102 can move synchronously with the traction rope in the same direction. In one embodiment, the electromagnetic radiation transmitting module 101 includes an X-ray emission source or a gamma-ray emission source, and the electromagnetic radiation detection module 102 includes a radiation detector.

[0031] Among them, X-rays and gamma rays are electromagnetic waves with extremely high frequency, extremely short wavelength and high energy. Due to their strong penetrating power, they can be used in industrial flaw detection. The radiation detector can be a FPD (Flat Panel Detector) or other detectors that can detect electromagnetic radiation.

[0032] Specifically, baffles can be provided on both sides of the electromagnetic radiation transmitting module 101 and the electromagnetic radiation detecting module 102 to prevent radiation from spilling out. To prevent the baffles from interfering with the operation of the traction rope, the baffles can be set to be retractable and fixed on the electromagnetic radiation transmitting module 101. During detection, the baffles are controlled to extend to the electromagnetic radiation detecting module 102, and retracted to the side of the electromagnetic radiation transmitting module 101 at other times.

[0033] In one embodiment, the traction rope detection device 100 further includes a lifting module 103, and the electromagnetic radiation emitting module 101 and the electromagnetic radiation detecting module 102 are both disposed on the lifting module 103. The lifting module 103 drives the electromagnetic radiation emitting module 101 and the electromagnetic radiation detecting module 102 to move synchronously with the traction rope in the same direction.

[0034] The lifting module 103 is specifically used to drive the electromagnetic radiation emitting module 101 and the electromagnetic radiation detecting module 102 to start from the target detection position in the elevator shaft when the elevator is running, and to run synchronously with the elevator's traction rope in the same direction, and after the running distance reaches a preset range, drive the electromagnetic radiation emitting module 101 and the electromagnetic radiation detecting module 102 to return to the target detection position in the elevator shaft. The preset range is the single effective detection length of the electromagnetic radiation detecting module 102. The lifting module 103 can be used to detect the damage status of the entire length of the traction rope at a limited height.

[0035] In one embodiment, the traction rope detection device 100 further includes an annular guide rail 104, which is arranged around the traction rope, and the lifting module 103 is movably arranged on the annular guide rail 104, thereby driving the electromagnetic radiation emission module 101 and the electromagnetic radiation detection module 102 to move around the traction rope.

[0036] Specifically, the lifting module 103 includes a lifting drive mechanism, a first lifting mechanism 103a and a second lifting mechanism 103b. The annular guide rail 104 includes a driving mechanism for driving the first lifting mechanism 103a and the second lifting mechanism 103b to rotate around the traction rope. The annular guide rail 104 is fixedly arranged in the elevator shaft, and the first lifting mechanism 103a and the second lifting mechanism 103b are respectively arranged on both sides of the traction rope; the first lifting mechanism 103a is provided with an electromagnetic radiation transmitting module 101, and the second lifting mechanism 103b is provided with an electromagnetic radiation detecting module 102.

[0037] The lifting drive mechanism is used to drive the electromagnetic radiation transmitting module 101 and the electromagnetic radiation detecting module 102 to move up and down on the first lifting mechanism 103a and the second lifting mechanism 103b. The first lifting mechanism 103a and the second lifting mechanism 103b can be specifically lifting guide rails. The preset range is the travel distance of the first lifting mechanism 103a and the second lifting mechanism 103b, and the target detection position is the travel end point of the first lifting mechanism 103a and the second lifting mechanism 103b.

[0038] The driving mechanism is connected to the first lifting mechanism 103a and the second lifting mechanism 103b respectively, and is used to drive the first lifting mechanism 103a and the second lifting mechanism 103b to move along the circular guide rail 104, so that the electromagnetic radiation transmitting module 101 and the electromagnetic radiation detecting module 102 move synchronously with the traction rope in the preset range in the direction of the elevator shaft. By moving the first lifting mechanism 103a and the second lifting mechanism 103b along the circular guide rail 104, the positions of the electromagnetic radiation transmitting module 101 and the electromagnetic radiation detecting module 102 relative to the traction rope are exchanged, so as to perform multi-directional and full-view detection of the traction rope.

[0039] The traction rope detection device 100 in this embodiment generates electromagnetic radiation through the electromagnetic radiation transmitting module 101, and the electromagnetic radiation detection module 102 receives the electromagnetic radiation and generates a detection signal of the traction rope, that is, the electromagnetic radiation is used to take images, so as to facilitate electromagnetic radiation detection of the damage state inside the traction rope. Since each electromagnetic radiation detection requires a certain exposure time, the electromagnetic radiation transmitting module 101 and the electromagnetic radiation detection module 102 are synchronized by the lifting module 103 to achieve a relatively static state with the traction rope during each electromagnetic radiation exposure process, so as to accurately obtain the traction rope image. It can also be used in the working process of the traction rope, so as to detect the damage state of the traction rope without affecting the operation of the elevator.

[0040] In one embodiment, if Figure 2 As shown, a traction rope detection system is provided, which includes the traction rope detection device 100 of any one of the above embodiments, a traction rope detection control device 200 and an image processing device 300.

[0041] The image processing device 300 is connected to the electromagnetic radiation detection module 102, and is used to receive the detection signal and determine the damage state recognition result of the traction rope according to the detection signal.

[0042] The traction rope detection control device 200 is connected to the traction rope detection device 100 and the image processing device 300 respectively; it is used to control the electromagnetic radiation emission module 101 and the electromagnetic radiation detection module 102 to run synchronously with the traction rope in the working state, and to obtain and output the damage state recognition result. Specifically, it is used to control the electromagnetic radiation emission module 101 and the electromagnetic radiation detection module 102 to run to the target detection position; if the elevator moves in the preset direction at the third running speed, the traction rope moves in the preset direction at the first running speed according to the traction ratio calculation, and synchronously controls the electromagnetic radiation emission module 101 and the electromagnetic radiation detection module 102 to move synchronously in the preset direction at the first running speed; while controlling the electromagnetic radiation emission module 101 and the electromagnetic radiation detection module 102 to move at the first running speed, the traction rope within the preset range is detected. After the detection is completed, the electromagnetic radiation emission module 101 and the electromagnetic radiation detection module 102 are controlled to run to the target detection position at the second running speed for the next detection.

[0043] In one of the embodiments, the traction rope detection system further includes a visible light image acquisition module.

[0044] The visible light image acquisition module is disposed on the electromagnetic radiation emission module 101 and connected to the traction rope detection control device 200 , and is controlled by the traction rope detection control device 200 to acquire and transmit the visible light image.

[0045] Specifically, the visible light image acquisition module includes a camera, and the traction rope detection control device 200 controls the camera to take pictures as needed. To make the structure simple, the visible light image acquisition module can be integrated on the electromagnetic radiation emission module 101.

[0046] The visible light image acquisition module can capture the state of the traction rope at a specific time as needed, thereby recording the state of the traction rope in the form of a visible light image.

[0047] In one embodiment, the image processing device 300 includes: an image conversion module 301 , an image processing module 302 , and a self-learning module 303 .

[0048] The image conversion module 301 is connected to the traction rope detection device 100, and is used to receive the detection signal and convert the detection signal into a digital signal.

[0049] In image processing, analog images record image brightness information through changes in the intensity of certain physical quantities (such as light, electricity, etc.). Digital images use digital arrays to express objective objects, which are essentially a collection of discrete sampling points, each of which has its own attributes. By converting analog images into digital images, the image of the traction rope is easier to process through the image processing module 302.

[0050] The image processing module 302 is connected to the image conversion module 301 and is used to process the digital signal into detection image information.

[0051] The image processing module 302 is specifically used to adjust the graphics, pixels, sharpness and splicing method of the image of the traction rope of the digital signal after analog-to-digital conversion, so that the presented image is closer to reality and easier to process.

[0052] The self-learning module 303 is connected to the image processing module 302 and the traction rope detection control device 200 respectively, and is used to determine the damage status recognition result of the traction rope based on the detection image information through the self-learning function recognition and judgment of the neural network algorithm, and finally transmit the damage status recognition result to the traction rope detection control device 200.

[0053] The self-learning module 303 learns through the preset artificial neural network learning criteria to improve the accuracy of the damage status recognition of the traction rope. Through the import of the database and learning based on certain rules, the traction rope detection system can distinguish the type and specific number of traction rope damage corresponding to the image, and make a grade assessment of the degree of damage according to relevant standards (enterprise standards, national standards, etc.) for reference by maintenance personnel. At the same time, the self-learning module 303 can also retrieve physical photos of any damaged area to determine surface damage. The self-learning module 303 is specifically implemented using existing technologies, which will not be repeated here.

[0054] In one embodiment, the image processing apparatus 300 further includes a data storage module 304 .

[0055] The data storage module 304 is connected to the image processing module 302 and the traction rope detection control device 200, respectively, and is used to store the detection image information. The traction rope detection control device 200 obtains the detection image information through the data storage module 304. The detection image information specifically includes the image data processed by the image processing module 302. By storing the detection image information of the traction rope, the historical damage of the traction rope can be recorded, and it is convenient to retrieve in subsequent detection.

[0056] In one embodiment, the traction rope detection system further includes an Internet of Things device 400 .

[0057] The Internet of Things device 400 is connected to the traction rope detection control device 200 and is used to send the damage status identification result to an external terminal.

[0058] The external terminal refers to a terminal device used to remotely or locally display the identification results of the damage status of the traction rope. The external terminal can also be used as a carrier for human-computer interaction for management personnel to obtain detection-related information and issue parameters and instructions. The parameters and instructions issued by the external terminal may include the detection time, detection times, damage judgment criteria of the traction rope, and processing logic of the traction rope detection.

[0059] In one of the embodiments, the traction rope detection system also includes an elevator control device 500; the elevator control device 500 is connected to the traction rope detection control device 200; and is used to send an elevator operation signal to the traction rope detection control device 200, and control the operation of the elevator according to the damage status identification result output by the traction rope detection control device 200.

[0060] Optionally, the elevator control device 500 can control the running speed of the elevator according to the detection requirements of the traction rope detection system, so that the traction rope and the electromagnetic radiation emission module 101 and the electromagnetic radiation detection module 102 can run synchronously. When the electromagnetic radiation emission module 101 and the electromagnetic radiation detection module 102 return to the fixed position in the elevator shaft, the running speed of the traction rope of the elevator is controlled so that the running distance of the traction rope reaches the preset range of the operation of the lifting module 103 in the electromagnetic radiation detection module 102, so that the adjacent parts of the traction rope can be continuously detected without stopping the elevator. And when damage is detected, the elevator is controlled to stop running for maintenance.

[0061] In one of the embodiments, the traction rope detection control device 200 can control the elevator to move at a third operating speed through the elevator control device 500, and the traction rope moves in the first direction at the first operating speed; the traction rope detection device 100 is controlled to capture and image the traction rope, and in each imaging process, the electromagnetic radiation emission module 101 and the electromagnetic radiation detection module 102 are controlled to move in the first direction at the first operating speed; the length of the traction rope that can be detected by the traction rope detection device 100 for each imaging is the first length, and the electromagnetic radiation emission module 101 and the electromagnetic radiation detection module 102 are controlled to move a first length relative to the traction rope in the length direction of the traction rope between two adjacent imaging shots.

[0062] In one embodiment, the traction rope detection control device 200 is used to control the electromagnetic radiation emission module 101 and the electromagnetic radiation detection module 102 to run from the first end point of the first lifting mechanism 103a and the second lifting mechanism 103b to the second end point at a first running speed and in a first direction during each imaging process.

[0063] In one embodiment, the traction rope detection control device 200 is used to control the electromagnetic radiation emission module 101 and the electromagnetic radiation detection module 102 to return from the second end point of the first lifting mechanism 103a and the second lifting mechanism 103b to the first end point at a second operating speed between two adjacent shooting images. When the electromagnetic radiation emission module 101 and the electromagnetic radiation detection module 102 return to the first end point, the traction rope moves a first length relative to the traction rope detection device 100. In this way, the reciprocating movement of the electromagnetic radiation emission module 101 and the electromagnetic radiation detection module 102 between the first end point and the second end point realizes the shooting of the entire length of the traction rope.

[0064] In one of the embodiments, the traction rope detection control device 200 is used to preset one of the first running speed, the second running speed, the third running speed, and the distance from the first end point to the second end point; based on the duration of each shooting imaging of the traction rope detection device 100, the first length and the elevator parameters, the other three of the first running speed, the second running speed, the third running speed, and the distance from the first end point to the second end point are calculated.

[0065] In one embodiment, the traction rope detection control device 200 is used to control the electromagnetic radiation emitting module 101 and the electromagnetic radiation detecting module 102 to rotate around the traction rope to different angles on the circular guide rail 104 after multiple shots and imaging, and to perform the next shot and imaging.

[0066] In one of the embodiments, the traction rope detection control device 200 is used to obtain the operating status information of the elevator through the elevator control device 500; based on the operating status information, determine whether the elevator meets the detection start condition; if so, control the elevator to run to the target detection position.

[0067] In one of the embodiments, the detection start condition includes: the current time period belongs to a preset detection time period, and the elevator is in an available state; wherein the elevator being in an available state means that the elevator is currently free of faults and the elevator has not received an operation instruction.

[0068] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
