Description

Technical Field

[0001] This application relates to the technical field of laser detection, and in particular to a method, system and terminal for detecting equipment deformation based on laser interferometry. Background Technology

[0002] Equipment deformation detection refers to the process of monitoring and analyzing the shape changes of mechanical equipment, structural components or other entities during use through various technical means.

[0003] In related technologies, equipment deformation detection mainly relies on workers using handheld measuring devices. Operators hold a laser rangefinder, aim at the point to be measured on the equipment, and trigger the measurement button. By comparing the distance data at different times, it can be analyzed whether the equipment has deformed.

[0004] Regarding the aforementioned technologies, using a handheld laser rangefinder for deformation detection often requires close-range detection. During this process, the equipment is very likely to be in operation, which could easily lead to personal injury or death. This results in low safety for equipment deformation detection and there is room for improvement. Summary of the Invention

[0005] To improve the safety of equipment deformation detection, this application provides a method, system, and terminal for equipment deformation detection based on laser interferometry.

[0006] Firstly, this application provides a method for detecting device deformation based on laser interferometry, employing the following technical solution:

[0007] Laser interferometry-based methods for detecting device deformation include:

[0008] Acquire the deformation detection trigger signal of the device;

[0009] The preset remote laser detection device is activated based on the deformation detection trigger signal, and the remote laser detection device is controlled to detect the equipment to generate equipment deformation detection parameters.

[0010] Obtain the non-deformation detection parameters of the equipment;

[0011] Determine whether the deformation detection parameters of the equipment meet the requirements for non-deformation detection parameters;

[0012] If the conditions are met, the remote laser detection device will continue to be controlled to detect the equipment in order to generate equipment deformation detection parameters;

[0013] If the parameters do not meet the requirements, the deformation detection parameters and non-deformation detection parameters of the equipment will be analyzed to determine the actual deformation parameters, and prompts will be given based on the actual deformation parameters.

[0014] By adopting the above technical solution, when the deformation detection trigger signal of the equipment is detected, the remote laser detection device is activated and the equipment is detected to obtain the equipment deformation detection parameters. After comparing the equipment deformation detection parameters with the non-deformation detection parameters, it is determined that the equipment has deformed. The actual deformation parameters are determined and a prompt is given, so that the operator does not need to approach the equipment for detection, thereby improving the safety of equipment deformation detection.

[0015] Optionally, the steps of controlling the remote laser inspection device to inspect the equipment to generate equipment deformation detection parameters include:

[0016] Obtain the device's startup and shutdown parameters;

[0017] Analyze the started parameters and preset device priority parameters to determine the started detection sequence;

[0018] Analyze the non-start parameters and device priority parameters to determine the non-start detection sequence;

[0019] Generate the actual detection order by associating the initiated and inactive detection sequences;

[0020] The remote laser inspection device is controlled according to the actual inspection sequence to inspect the equipment and generate equipment deformation detection parameters.

[0021] By adopting the above technical solution, the starting detection sequence is determined according to the starting parameters and equipment priority parameters, so that the higher priority equipment among the starting equipment is detected first. Then, the non-starting detection sequence is determined according to the non-starting parameters and equipment priority parameters. After the starting equipment is detected, the non-starting equipment is detected according to the equipment priority, so as to ensure the quality of the equipment in use and improve the accuracy and reliability of equipment deformation detection.

[0022] Optionally, the steps of controlling the remote laser inspection device to inspect the equipment according to the actual inspection sequence to generate equipment deformation inspection parameters include:

[0023] The actual testing equipment is obtained based on the actual testing sequence;

[0024] Obtain the occlusion status detection results of the actual testing equipment;

[0025] Determine whether the occlusion detection result meets the preset requirements for an unoccluded state;

[0026] If the conditions are met, the remote laser detection device will be controlled to detect the actual equipment according to the preset direct detection method to generate equipment deformation detection parameters;

[0027] If the conditions are not met, the remote laser detection device will be controlled to detect the actual equipment according to the preset reflection detection method to generate equipment deformation detection parameters.

[0028] By adopting the above technical solution, the occlusion detection results of the actual testing equipment are retrieved. When the occlusion detection results meet the requirements of the unoccluded state, it indicates that the detection point of the equipment is unobstructed. Therefore, the remote laser detection device is controlled according to the direct detection method to detect the actual testing equipment and obtain the equipment deformation detection parameters. When the results do not meet the requirements, it indicates that the detection point of the equipment is obstructed. Therefore, the remote laser detection device is controlled according to the reflection detection method to detect the actual testing equipment and obtain the equipment deformation detection parameters, thereby improving the accuracy and convenience of equipment deformation detection.

[0029] Optionally, the steps for obtaining the occlusion status detection results of the actual detection equipment include:

[0030] The laser detection parameters are determined based on the relationship between the actual detection equipment and the preset equipment detection parameters.

[0031] The remote laser detection device is controlled to perform preliminary detection on the actual detection equipment based on the laser detection parameters, so as to generate preliminary distance parameters;

[0032] Determine whether the preliminary distance parameters meet the requirements of the laser detection parameters;

[0033] If the conditions are met, the preset unoccluded result is defined as the occlusion state detection result.

[0034] If the condition is not met, an occlusion detection image is obtained based on the preliminary distance parameters;

[0035] The occlusion detection image is subjected to image segmentation and recognition analysis to determine the occlusion state detection result.

[0036] By adopting the above technical solution, after the remote laser detection device performs preliminary detection on the actual detection equipment and obtains preliminary distance parameters, if it is determined that the preliminary distance parameters do not meet the requirements of the laser detection parameters, an occlusion detection image is acquired based on the preliminary distance parameters, and the occlusion state detection result is determined based on the occlusion detection image, thereby improving the accuracy of determining the occlusion state detection result.

[0037] Optionally, the step of controlling a remote laser detection device to detect the actual equipment according to a preset direct-light detection method to generate equipment deformation detection parameters includes:

[0038] Obtain the displacement detection results and actual laser parameters of the actual detection equipment;

[0039] Determine whether the displacement detection results meet the preset requirements for a no-displacement state;

[0040] If the conditions are met, the remote laser detection device will be controlled to detect the actual equipment based on the actual laser parameters in order to generate equipment deformation detection parameters.

[0041] If not, obtain the actual displacement angle and displacement hypotenuse length of the actual testing equipment;

[0042] The actual displacement angle and the length of the hypotenuse are analyzed to determine the movement parameters;

[0043] The remote laser detection device is controlled to adjust its position based on the movement parameters, and is also controlled to detect the actual equipment based on the actual laser parameters to generate equipment deformation detection parameters.

[0044] By adopting the above technical solution, when the displacement detection result does not meet the requirements of the no-displacement state, it indicates that the actual detection equipment has been displaced, which may lead to inaccurate deformation detection. Therefore, the actual displacement angle and displacement hypotenuse length of the actual detection equipment are detected, and the movement parameters are calculated based on the two. This allows the remote laser detection device to be controlled to adjust its position according to the movement parameters. Then, the remote laser detection device is controlled to detect the actual detection equipment based on the actual laser parameters, thereby improving the accuracy of equipment deformation detection.

[0045] Optionally, the steps of controlling a remote laser detection device to detect the actual equipment according to a preset reflection detection method to generate equipment deformation detection parameters include:

[0046] Obtain the displacement detection results from the actual testing equipment;

[0047] Determine whether the displacement detection results meet the preset requirements for a no-displacement state;

[0048] If it does not meet the requirements, a prompt will be given based on the preset occlusion displacement prompt information;

[0049] If the conditions are met, the preset reflection device is activated, and the reflection device is controlled to assist the remote laser detection device in detecting the actual equipment to generate equipment deformation detection parameters.

[0050] By adopting the above technical solution, when the displacement detection result meets the requirement of no displacement, it indicates that although the equipment is blocked, no displacement has occurred, which meets the requirements of reflection detection. Therefore, the reflection device is activated and controlled to assist the remote laser detection device in detecting the actual equipment, thereby improving the convenience of equipment deformation detection.

[0051] Optionally, the steps of controlling the reflection device to assist the remote laser detection device in detecting the actual detection equipment to generate equipment deformation detection parameters include:

[0052] The reflection detection parameters are determined based on the relationship between the actual detection equipment and the preset equipment reflection parameters.

[0053] The position and angle of the reflection device are adjusted according to the reflection detection parameters.

[0054] The emission detection parameters are determined based on the relationship between the actual detection equipment and the preset equipment emission parameters.

[0055] Based on the emission detection parameters, the remote laser detection device is controlled to adjust the angle and emit a laser towards the reflecting device. The reflecting device then reflects the laser onto the actual detection equipment for detection, thereby generating equipment deformation detection parameters.

[0056] By adopting the above technical solution, the position and angle of the reflecting device are adjusted according to the reflection detection parameters, thereby ensuring that the reflecting device can accurately reflect the laser of the remote laser detection device around the obstruction onto the equipment. The remote laser detection device is then adjusted according to the emission detection parameters and emitted into the reflecting device, thereby improving the accuracy of equipment deformation detection.

[0057] Optionally, the steps for obtaining the displacement detection results of the actual detection equipment include:

[0058] Acquire displacement detection images from the actual detection equipment;

[0059] Image recognition analysis is performed on the displacement detection image and the preset coordinate system to determine the coordinates of the detected edges;

[0060] Determine whether the coordinates of the detected edge meet the preset requirements for displacement-free coordinates;

[0061] If the conditions are met, the preset no-displacement result will be defined as the displacement detection result.

[0062] If it does not meet the requirements, the preset displacement result will be defined as the displacement detection result.

[0063] By adopting the above technical solution, displacement detection images of actual detection equipment are acquired, and the coordinate system is mapped onto the displacement detection image to identify the detection edge coordinates. When the detection edge coordinates meet the requirements of no displacement coordinates, it indicates that the equipment has not been displaced, so the no displacement result is defined as the displacement detection result. When they do not meet the requirements, it indicates that the equipment has been displaced, so the displacement result is defined as the displacement detection result, thereby improving the accuracy of determining the displacement detection result.

[0064] Secondly, this application provides a device deformation detection system based on laser interferometry, which adopts the following technical solution:

[0065] A laser interferometry-based device deformation detection system includes:

[0066] The acquisition module is used to acquire the deformation detection trigger signal and the non-deformation detection parameters;

[0067] A memory for storing a program for a laser interferometry-based device deformation detection method as described in any of the preceding claims;

[0068] The processor and the program in the memory can be loaded and executed by the processor to implement the laser interferometry-based device deformation detection method as described in any of the above.

[0069] By adopting the above technical solution, the processor loads and executes the program of the laser interferometry-based equipment deformation detection method stored in the memory, and controls the acquisition module to acquire a series of data related to the laser interferometry-based equipment deformation detection. When the deformation detection trigger signal of the equipment is detected, the remote laser detection device starts and detects the equipment to obtain the equipment deformation detection parameters. After comparing the equipment deformation detection parameters with the no-deformation detection parameters, it is determined that the equipment has deformed. The actual deformation parameters are determined and a prompt is given, so that the operator does not need to approach the equipment for detection, thereby improving the safety of equipment deformation detection.

[0070] Thirdly, this application provides a smart terminal, which adopts the following technical solution:

[0071] A smart terminal includes a memory and a processor, wherein the memory stores a computer program that can be loaded by the processor and executed as described in any of the preceding claims, a laser interferometry-based device deformation detection method.

[0072] By adopting the above technical solution, the processor loads and executes the computer program for the equipment deformation detection method based on laser interferometry stored in the memory through the operation of the smart terminal. When the deformation detection trigger signal of the equipment is detected, the remote laser detection device starts and detects the equipment to obtain the equipment deformation detection parameters. After comparing the equipment deformation detection parameters with the no-deformation detection parameters, the actual deformation parameters are determined and a prompt is given when the equipment is deformed. This eliminates the need for operators to approach the equipment for detection, thereby improving the safety of equipment deformation detection.

[0073] In summary, this application includes at least one of the following beneficial technical effects:

[0074] 1. When a deformation detection trigger signal is detected, the remote laser detection device starts and detects the equipment to obtain the equipment deformation detection parameters. The equipment deformation detection parameters are then compared with the non-deformation detection parameters to determine when the equipment has deformed. The actual deformation parameters are determined and a prompt is given, thus eliminating the need for operators to approach the equipment for detection, thereby improving the safety of equipment deformation detection.

[0075] 2. By referencing the occlusion detection results of the actual testing equipment, if the occlusion detection results meet the requirements of an unoccluded state, it indicates that the detection point of the equipment is unobstructed. Therefore, the remote laser detection device is controlled according to the direct detection method to detect the actual testing equipment and obtain the equipment deformation detection parameters. If the results do not meet the requirements, it indicates that the detection point of the equipment is obstructed. Therefore, the remote laser detection device is controlled according to the reflection detection method to detect the actual testing equipment and obtain the equipment deformation detection parameters, thereby improving the accuracy and convenience of equipment deformation detection.

[0076] 3. When the displacement detection result does not meet the requirement of no displacement, it indicates that the actual detection equipment has been displaced, which may lead to inaccurate deformation detection. Therefore, the actual displacement angle and displacement hypotenuse length of the actual detection equipment are detected, and the movement parameters are calculated based on the two. The remote laser detection device is then controlled to adjust its position according to the movement parameters. The remote laser detection device is then controlled to detect the actual detection equipment based on the actual laser parameters, thereby improving the accuracy of equipment deformation detection.

[0087] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figures 1 to 10 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0088] This application discloses a device deformation detection method based on laser interferometry. Specifically, it discloses a processing terminal and a remote laser detection device. The processing terminal and the remote laser detection device are communicatively connected to achieve data interaction and control. When the processing terminal receives a device deformation detection trigger signal, it responds to the signal and controls the remote laser detection device to detect the device and generate device deformation detection parameters. The processing terminal compares the device deformation detection parameters with the non-deformation detection parameters. If the device deformation detection parameters do not meet the requirements of the non-deformation detection parameters, it indicates that the device has deformed. Therefore, the actual deformation parameters are determined based on the device deformation detection parameters and the non-deformation detection parameters, and a prompt is given based on the actual deformation parameters. This eliminates the need for personnel to approach the device for detection, thereby improving the safety of device deformation detection.

[0089] Reference Figure 1 This application discloses a device deformation detection method based on laser interferometry, including the following steps:

[0090] Step S100: Obtain the deformation detection trigger signal of the device.

[0091] The deformation detection trigger signal refers to the signal that starts deformation detection of the device. In one embodiment, it is input by the operator in the processing terminal; in another embodiment, the deformation detection trigger signal is activated by the processing terminal according to the time period.

[0092] Step S101: Activate the preset remote laser detection device according to the deformation detection trigger signal, and control the remote laser detection device to detect the equipment to generate equipment deformation detection parameters.

[0093] When the processing terminal receives a deformation detection trigger signal, it responds to the signal by activating the remote laser detection device and issuing commands to control the device to perform deformation detection on the equipment. The specific method is described in [reference needed]. Figure 2 This process provides data support for subsequent determination of whether the equipment has undergone deformation.

[0094] A remote laser inspection device is a device that uses a remote laser to detect the deformation of equipment. Based on the principle of light interference, it includes a light source, an interference system, and a data analysis system. The light source is usually a single-frequency or dual-frequency laser that provides stable coherent light. The interference system splits the beam into two parts: one part illuminates the equipment, and the other part serves as a reference beam. When the two beams re-merge, the phase difference caused by the path difference will form interference fringes on the detector. The data analysis system can accurately calculate the deformation characteristics of the equipment by analyzing the number and changes of the interference fringes.

[0095] Equipment deformation detection parameters refer to the distance parameters obtained by the remote laser detection device to detect the equipment, that is, the distance between the remote laser detection device and the point to be measured on the equipment.

[0096] Step S102: Obtain the non-deformation detection parameters of the device.

[0097] Among them, the non-deformation detection parameter refers to the distance between the remote laser detection device and the point to be measured on the equipment when the equipment has not undergone deformation. There are three types: one is the non-deformation detection parameter when the equipment has no displacement and no obstruction, which is the most standard value; another is the non-deformation detection parameter when the equipment has displacement and no obstruction, which is obtained by adding or subtracting the displacement amount from the standard value; and the last is the non-deformation detection parameter when the equipment has no displacement but obstruction, which is the sum of a direct path and a reflected path. The specific value is determined by the operator based on the distance between the remote laser detection device and the point to be measured, and the processing terminal selects and uses it according to the status of the equipment.

[0098] Step S103: Determine whether the deformation detection parameters of the equipment meet the requirements for non-deformation detection parameters.

[0099] The requirement for intangible deformation detection parameters is that they must be consistent with those for intangible deformation detection parameters. The processing terminal determines whether the equipment's deformation detection parameters are consistent with the intangible deformation detection parameters, thereby determining whether the distance between the remote laser detection device and the point to be measured on the equipment has changed.

[0100] Step S1031: If the condition is met, continue to control the remote laser detection device to detect the equipment to generate equipment deformation detection parameters.

[0101] If the processing terminal determines that the deformation detection parameters of the equipment are consistent with the non-deformation detection parameters, it indicates that the distance between the remote laser detection device and the point to be measured on the equipment has not changed, so the point to be measured has not deformed. Therefore, the remote laser detection device is controlled to continue to detect the equipment and obtain the deformation detection parameters of the equipment, so as to continuously monitor the deformation of the equipment.

[0102] Step S1032: If it does not meet the requirements, analyze the deformation detection parameters and the non-deformation detection parameters of the equipment to determine the actual deformation parameters, and provide a prompt based on the actual deformation parameters.

[0103] If the processing terminal determines that the deformation detection parameters and the non-deformation detection parameters of the equipment are inconsistent, it indicates that the detection points on the equipment have deformed. Therefore, after analyzing the deformation detection parameters and the non-deformation detection parameters, the actual deformation parameters are determined and the actual deformation parameters are used to provide a prompt, which facilitates maintenance by personnel.

[0104] Actual deformation parameters refer to the actual deformation that occurs in the equipment, which are obtained by interpolating the deformation detection parameters and the non-deformation detection parameters of the equipment using the processing terminal.

[0105] Reference Figure 2 The steps for controlling a remote laser inspection device to inspect equipment and generate equipment deformation detection parameters include:

[0106] Step S200: Obtain the device's startup parameters and non-startup parameters.

[0107] Among them, the started parameters refer to the parameters of the devices that have been started, and the unstarted parameters refer to the parameters of the devices that have not been started. The started devices send their device identifiers to the processing terminal to obtain the started parameters. The processing terminal identifies the devices that have not sent their device identifiers based on all device identifiers, thereby obtaining the unstarted parameters.

[0108] Step S201: Analyze the started parameters and preset device priority parameters to determine the started detection sequence.

[0109] Among them, the equipment priority parameter refers to the priority order of all equipment in deformation detection, which is determined by the operator according to the importance of the equipment and uploaded to the processing terminal.

[0110] The initiated detection order refers to the priority order in which deformation detection is performed on devices that have already been started. It is obtained by the processing terminal sorting the devices corresponding to the initiated parameters according to the device priority parameters.

[0111] Step S202: Analyze the non-start parameters and device priority parameters to determine the non-start detection sequence.

[0112] The "not started detection order" refers to the priority order of deformation detection in devices that have not been started. It is obtained by the processing terminal sorting the devices corresponding to the "not started" parameter according to the device priority parameter.

[0113] Step S203: Generate the actual detection sequence by associating the started and unstarted detection sequences.

[0114] The actual detection sequence refers to the actual order in which the remote laser detection device detects all equipment. It is obtained by the processing terminal placing the detected devices in the first position and the undetected devices in the last position.

[0115] Step S204: Control the remote laser detection device to detect the equipment according to the actual detection sequence to generate equipment deformation detection parameters.

[0116] After determining the actual testing sequence, the processing terminal controls the remote laser detection device to test each device according to the actual testing sequence, thereby obtaining the device deformation detection parameters. The specific method is described in [reference needed]. Figure 3 This process improves the reliability of deformation detection.

[0117] Reference Figure 3 The steps for controlling a remote laser inspection device to inspect the equipment according to the actual inspection sequence to generate equipment deformation inspection parameters include:

[0118] Step S300: Obtain the actual testing equipment based on the actual testing sequence.

[0119] The actual testing equipment refers to the equipment that the remote laser testing device is currently testing. The processing terminal selects the actual testing equipment one by one according to the equipment order corresponding to the actual testing sequence.

[0120] Step S301: Obtain the occlusion status detection results of the actual detection equipment.

[0121] The occlusion status detection result refers to the detection result of whether the detection point of the actual detection equipment is occluded by an obstacle, including two results: occluded and unoccluded. The specific method for obtaining this result is described in [reference needed]. Figure 4 The steps.

[0122] Step S302: Determine whether the occlusion state detection result meets the preset requirements for the unoccluded state.

[0123] Among them, the unobstructed state refers to the state in which the detection points of the equipment are not obstructed, and the requirement for the unobstructed state is to be consistent with the unobstructed state.

[0124] By processing the terminal to determine whether the state corresponding to the occlusion detection result is consistent with the unoccluded state, it can be determined whether there are obstacles in front of the detection point of the device that affect the remote laser detection device from detecting the detection point.

[0125] Step S3021: If the conditions are met, the remote laser detection device is controlled to detect the actual equipment according to the preset direct detection method to generate equipment deformation detection parameters.

[0126] If the processing terminal determines that the state corresponding to the occlusion detection result is consistent with the unoccluded state, it indicates that there is no obstacle obstructing the detection point of the device. Therefore, the device deformation detection parameters are obtained after the remote laser detection device is controlled to detect the actual detection device according to the direct detection method. The specific method is as follows: Figure 5 The steps.

[0127] The direct laser detection method refers to the method in which a remote laser detection device directly emits a laser beam to the detection point on the equipment for detection, and the data is stored in the processing terminal by the operator.

[0128] Step S3022: If it does not meet the requirements, then control the remote laser detection device to detect the actual detection equipment according to the preset reflection detection method to generate equipment deformation detection parameters.

[0129] If the processing terminal determines that the state corresponding to the occlusion detection result is inconsistent with the unoccluded state, it indicates that there is an obstacle obstructing the detection point of the device. Therefore, the remote laser detection device cannot accurately detect the deformation of the device through direct light. Instead, it uses a reflection detection method to control the remote laser detection device to detect the actual device and obtain the device deformation detection parameters. The specific method is described in [reference needed]. Figure 6 The steps.

[0130] Reference Figure 4 The steps for obtaining the occlusion status detection results of the actual detection equipment include:

[0131] Step S400: Determine the laser detection parameters based on the relationship between the actual detection equipment and the preset equipment detection parameters.

[0132] Among them, the equipment detection parameter relationship refers to the correspondence between the equipment and the laser detection parameters. Different equipment requires different directions, positions and distances for the laser emitted by the remote laser detection device. Therefore, the operator forms a mapping table by matching the direction, position and distance of the laser emitted by the equipment and the remote laser detection device one by one according to the actual situation of the equipment and the remote laser detection device.

[0133] Laser detection parameters refer to the position and direction of the laser emitted by the remote laser detection device to the equipment, which are obtained by the processing terminal by looking up the corresponding mapping table of equipment detection parameters based on the actual detection equipment.

[0134] Step S401: Control the remote laser detection device to perform preliminary detection on the actual detection equipment according to the laser detection parameters, so as to generate preliminary distance parameters.

[0135] In this process, after determining the laser detection parameters, the remote laser detection device is controlled to directly shine a laser on the actual detection equipment at the location corresponding to the laser detection parameters in the direction corresponding to the laser detection parameters, thereby obtaining preliminary distance parameters and providing data support for subsequent determination of whether the equipment is blocked.

[0136] Preliminary distance parameters refer to the distance values ​​obtained when a remote laser detection device performs its first detection on a point to be measured on the device at a standard position and orientation.

[0137] Step S402: Determine whether the preliminary distance parameters meet the requirements of the laser detection parameters.

[0138] The requirement for laser detection parameters refers to being within the error range of the laser distance specified in the laser detection parameters. The specific error range is determined by the operator based on the actual situation.

[0139] By processing the terminal to determine whether the preliminary distance parameters are within the error range of the laser distance in the laser detection parameters, it can be determined whether there may be obstacles at the detection point of the equipment.

[0140] Step S4021: If the condition is met, the preset unobstructed result is defined as the occlusion state detection result.

[0141] If the processing terminal determines that the preliminary distance parameter is within the error range of the laser distance in the laser detection parameter, it indicates that the preliminary detected distance is very close to the distance without deformation. At this time, there is no obstacle blocking the distance, so the unobstructed result is defined as the occlusion state detection result.

[0142] Unobstructed results refer to results where there are no obstacles obstructing the detection points of the equipment, and are stored in the processing terminal by the operator.

[0143] Step S4022: If it does not meet the requirements, then obtain the occlusion detection image based on the preliminary distance parameters.

[0144] If the processing terminal determines that the preliminary distance parameter is not within the error range of the laser distance in the laser detection parameter, it indicates that there is likely an obstacle in front of the detection point of the device. Therefore, the occlusion detection image is collected according to the preliminary distance parameter to provide data support for the subsequent determination of the occlusion status.

[0145] An occlusion detection image refers to an image of the location where an obstacle may exist. It is obtained by a movable image acquisition component on a remote laser detection device after moving a distance corresponding to the initial distance parameter.

[0146] Step S403: Perform image segmentation and recognition analysis on the occlusion detection image to determine the occlusion state detection result.

[0147] In this step, the occlusion state detection result is consistent with the occlusion state detection result in step S301. The processing terminal calls the occlusion detection image and inputs the occlusion detection image into the trained convolutional neural network for image recognition, thereby determining whether there is an obstacle in the image. If there is an obstacle, the occlusion result is defined as the occlusion state detection result; if there is no obstacle, the no-occlusion result is defined as the occlusion state detection result.

[0148] Reference Figure 5 The steps for controlling a remote laser detection device to detect actual equipment according to a preset direct-light detection method to generate equipment deformation detection parameters include:

[0149] Step S500: Obtain the displacement detection results and actual laser parameters of the actual detection equipment.

[0150] The displacement detection result refers to the detection result of whether the actual detection equipment has experienced displacement, including both displacement and no displacement. Specific detection methods are detailed in [reference needed]. Figure 8 The steps are as follows. The actual laser parameters in this step are actually the same as the laser detection parameters in step S400, and will not be described in detail here.

[0151] Step S501: Determine whether the displacement detection result meets the preset requirements for a no-displacement state.

[0152] Among them, the state of no displacement refers to the state in which the actual detection equipment has not been displaced, and the requirement of the state of no displacement is that it is consistent with the state of no displacement.

[0153] The processing terminal determines whether the displacement detection result is consistent with the state of no displacement, thereby determining whether the actual detection equipment has experienced displacement.

[0154] Step S5011: If the conditions are met, the remote laser detection device is controlled to detect the actual detection equipment according to the actual laser parameters to generate equipment deformation detection parameters.

[0155] If the processing terminal determines that the displacement detection result is consistent with the state of no displacement, it indicates that the actual detection equipment has not undergone displacement. Therefore, the remote laser detection device is controlled to emit a laser at the actual detection equipment at the position corresponding to the actual laser parameters and in the direction corresponding to the actual laser parameters, so as to obtain the deformation detection parameters of the equipment after detecting the actual detection equipment.

[0156] Step S5012: If not, obtain the actual displacement angle and displacement hypotenuse length of the actual detection equipment.

[0157] If the processing terminal determines that the displacement detection result is inconsistent with the no-displacement state, it indicates that the actual detection equipment has experienced displacement. Figure 9 Since the detection point has shifted from its original position, emitting the laser at the position corresponding to the actual laser parameters may lead to inaccurate detection. The remote laser detection device needs to be adjusted in at least one direction to ensure that the laser accurately illuminates the detection point. Therefore, the actual displacement angle and displacement slope length of the actual detection device are detected to provide data support for subsequent control of the remote laser detection device.

[0158] The actual displacement angle refers to the actual displacement angle of the detection equipment, as referenced. Figure 9 An industrial camera captures images above the actual inspection equipment, mapping the coordinate system onto the image. The angle between the contour of the inspection point and the baseline is identified. The angle is determined by calculating the trigonometric function of the angle by the quotient of the number of pixels on the two sides, and then finding the inverse function. The displacement hypotenuse length refers to the distance between a fixed point on the equipment and the inspection point, as shown in the reference... Figure 9 The processing terminal identifies the number of pixels between the fixed point and the detection point, and then multiplies the distance represented by the pixels by the number to obtain the actual length.

[0159] Step S502: Analyze the actual displacement angle and the length of the displacement hypotenuse to determine the movement parameters.

[0160] Among them, the movement parameters refer to the direction and distance that the remote laser detection device needs to adjust, as shown in the reference. Figure 9 The processing terminal determines the movement direction based on the actual displacement angle, calculates the cosine value based on the actual displacement angle, and then calculates the product of the cosine value and the length of the displacement hypotenuse to obtain the length of the mapping point of the detection point on the original contour after movement. Finally, the difference between the length of the displacement hypotenuse and the length of the mapping point is calculated to obtain the distance. Thus, the movement parameters are obtained by associating the direction and distance.

[0161] Step S503: Adjust the position of the remote laser detection device according to the movement parameters, and control the remote laser detection device to detect the actual detection equipment according to the actual laser parameters to generate equipment deformation detection parameters.

[0162] In this process, after determining the movement parameters, the processing terminal controls the remote laser detection device to adjust its position according to the direction and distance corresponding to the movement parameters, and emits lasers to the detection points of the actual detection equipment according to the direction corresponding to the actual laser parameters, thereby detecting the actual detection equipment and obtaining the equipment deformation detection parameters.

[0163] Reference Figure 6The steps for controlling a remote laser detection device to detect actual equipment according to a preset reflection detection method to generate equipment deformation detection parameters include:

[0164] Step S600: Obtain the displacement detection results of the actual detection equipment.

[0165] The displacement detection results in this step are consistent with those in step S500, and will not be described again here.

[0166] Step S601: Determine whether the displacement detection result meets the preset requirements for a no-displacement state.

[0167] The requirements for the no-displacement state in this step are the same as those in step S501, and will not be repeated here.

[0168] By processing the terminal to determine whether the displacement detection result is consistent with the state of no displacement, it can be determined whether the actual detection device that was blocked has been displaced.

[0169] Step S6011: If it does not meet the requirements, a prompt will be made according to the preset occlusion displacement prompt information.

[0170] If the processing terminal determines that the displacement detection result is inconsistent with the state of no displacement, it indicates that the actual detection equipment that was blocked has also moved. The remote laser detection device has a high difficulty in detecting the equipment. Therefore, it provides a prompt based on the obstruction displacement prompt information, so that personnel can remove the obstruction or adjust the actual detection equipment.

[0171] The obstruction displacement warning information refers to the information that the actual detection equipment is obstructed and has been displaced, and is stored in the processing terminal by the operator.

[0172] Step S6012: If the conditions are met, the preset reflection device is activated, and the reflection device is controlled to assist the remote laser detection device in detecting the actual detection equipment to generate equipment deformation detection parameters.

[0173] If the processing terminal determines that the displacement detection result is consistent with the no-displacement state, it indicates that the actual detection equipment that was blocked has not undergone displacement. The actual detection equipment can then be detected using a reflection method. Therefore, the reflection device is activated, and after controlling the reflection device to assist the remote laser detection device in detecting the actual detection equipment, the equipment deformation detection parameters are obtained. The specific method is described in [reference needed]. Figure 7 The steps.

[0174] A reflecting device is a device used to reflect laser light so that it bypasses obstructions and shines on the equipment. High reflectivity mirrors can be used.

[0175] Reference Figure 7The steps for controlling the reflection device to assist the remote laser detection device in detecting the actual detection equipment to generate equipment deformation detection parameters include:

[0176] Step S700: Determine the reflection detection parameters based on the actual detection equipment and the preset equipment reflection parameter relationship.

[0177] Among them, the equipment reflection parameter relationship refers to the correspondence between different equipment and reflection detection parameters. The midpoint position and extension direction between different equipment and the remote laser detection device are different. The operator forms a mapping table by matching the midpoint position and extension direction between different equipment and the remote laser detection device.

[0178] The reflection detection parameters refer to the position and direction of the reflected laser light from the remote laser detection device assisted by the reflection device. These parameters are obtained by the processing terminal by looking up the corresponding mapping table of the device reflection parameters based on the actual detection equipment.

[0179] Step S701: Adjust the position and angle of the reflection device according to the reflection detection parameters.

[0180] Among them, after obtaining the reflection detection parameters, refer to Figure 10 The reflector is adjusted to the position corresponding to the reflection detection parameters, which is the midpoint between the actual detection equipment and the remote laser detection device. This ensures that the reflector can reflect the laser around the obstruction. The angle is adjusted in the direction corresponding to the reflection detection parameters, which is the direction of the line connecting the actual detection equipment and the remote laser detection device. This ensures that the reflected laser can accurately illuminate the detection point.

[0181] Step S702: Determine the transmission detection parameters based on the relationship between the actual detection equipment and the preset equipment transmission parameters.

[0182] Among them, the equipment emission parameter relationship refers to the correspondence between different equipment and emission detection parameters. Different equipment requires the remote laser detection device to emit lasers to the reflection device at different positions and directions. The operator forms a mapping table by matching the different equipment with the position and direction of the emitted laser.

[0183] The emission detection parameters refer to the position and direction of the laser emitted by the remote laser detection device to the midpoint of the reflecting device, as referenced. Figure 10 The processing terminal finds the value in the mapping table corresponding to the device transmission parameter relationship based on the actual detection device.

[0184] Step S703: After adjusting the angle of the remote laser detection device according to the emission detection parameters, the laser is emitted towards the reflection device, and the reflection device reflects the laser onto the actual detection equipment for detection, so as to generate equipment deformation detection parameters.

[0185] After determining the emission detection parameters, the processing terminal adjusts the angle of the remote laser detection device according to the direction corresponding to the emission detection parameters. The position is actually consistent with the position of direct detection and does not change. After adjusting the angle, the remote laser detection device emits laser towards the reflection device. At this time, the reflection device reflects the laser to the detection point on the actual detection equipment, thereby obtaining the equipment deformation detection parameters after detecting the detection point of the actual detection equipment.

[0186] Reference Figure 8 The steps for obtaining displacement detection results from actual detection equipment include:

[0187] Step S800: Obtain the displacement detection image of the actual detection equipment.

[0188] Among them, displacement detection images refer to images of the actual detection equipment, which are captured by an industrial camera on top of the actual detection equipment.

[0189] Step S801: Perform image recognition analysis on the displacement detection image and the preset coordinate system to determine the coordinates of the detection edge.

[0190] Among them, the detection edge coordinates refer to the coordinates of the detected contour in the displacement detection image in the coordinate system. The processing terminal maps the coordinate system onto the displacement detection image, identifies the detected contour in the displacement detection image, and then identifies the coordinates of the corresponding contour to obtain the detection edge coordinates.

[0191] Step S802: Determine whether the coordinates of the detected edge meet the preset requirements for displacement-free coordinates.

[0192] Among them, the displacement-free coordinates refer to the coordinates of the detected edge when the equipment has not moved. The requirement for the displacement-free coordinates is that they are consistent with the displacement-free coordinates.

[0193] The processing terminal determines whether the coordinates of the detected edge are consistent with the coordinates without displacement, thereby determining whether the detected edge has shifted.

[0194] Step S8021: If the condition is met, the preset no displacement result is defined as the displacement detection result.

[0195] If the processing terminal determines that the coordinates of the detected edge are consistent with the coordinates of the non-displaced edge, it indicates that the detected edge has not shifted, and therefore the non-displaced result is defined as the displacement detection result.

[0196] A no-displacement result refers to a result where no displacement of the equipment occurs, which is stored in the processing terminal by the operator.

[0197] Step S8022: If it does not meet the requirements, the preset displacement result is defined as the displacement detection result.

[0198] If the processing terminal determines that the coordinates of the detected edge are inconsistent with the coordinates without displacement, it indicates that the detected edge has shifted. Therefore, the result with displacement is defined as the displacement detection result.

[0199] Displacement results refer to the results of equipment displacement, which are stored in the processing terminal by the operator.
