It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0047] In a core concept of an embodiment of the present invention, in terms of internal electrical data, a data correspondence between the car load weight and the magnetic buffer is established, and a data curve is generated by fitting according to the data correspondence. The data in the data curve is used as training metadata and input into the artificial intelligence model for training to obtain a trained artificial intelligence model.

The speed exceeding the threshold can be calculated based on the moving distance between the image pixels, and it can be judged whether the car speed is too high, and whether the appearance of the hardware device is damaged can be identified, further enhancing the detectability of the device appearance, and achieving the effect of detecting whether the appearance of the device is damaged.
[0048] Reference Figure 1 , a schematic diagram showing an embodiment of a maintenance control method for a home elevator according to an embodiment of the present invention is shown, wherein the home elevator includes an elevator car and a guide rail; a plurality of magnetic dampers are provided at different positions of the guide rail; and the method may specifically include the following steps:
[0049] Step S101: Acquire historical weight data of the elevator car;
[0050] In an embodiment of the present invention, the home elevator includes an elevator car and guide rails, and further includes a control device such as a controller. The control device can be connected to various systems of the home elevator, including a traction system, a guide system, a door system, a weight balancing system, and an electric traction system.
[0051] The guide system may include guide rails, which can be used to limit the freedom of movement of the car and counterweight, so that they can only move up and down along the guide rails. The guide system may also include components such as guide shoes and guide rail frames. In addition, the traction system may include traction wire ropes, guide pulleys, and return pulleys, which are mainly responsible for outputting and transmitting power to move the elevator up and down. The door system includes car doors, landing doors, door openers, and door locking devices, which are used to seal or open the car entrance.
[0052] The weight balancing system may include a counterweight and a weight compensation device. The weight balancing system can balance the weight of the car to ensure the normal operation of the elevator's traction transmission. The electric traction system is a system that cooperates with the traction system, which mainly includes a traction motor, a power supply system, a speed feedback device, and a motor speed regulating device. The traction motor is connected to the traction wire rope of the traction system to provide power for the up and down movement of the elevator. On the other hand, the control device can also be connected to devices such as a position display device, a control panel, and a floor selector to control the displayed information. In addition, the home elevator may also include other safety protection devices, such as a speed limiter, a safety clamp, a buffer, a magnetic damper, an end station protection device, a weight sensor, etc., and the embodiments of the present invention do not impose too many restrictions on this.
[0053] Specifically applied to an embodiment of the present invention, the home elevator includes an elevator car and a guide rail; a plurality of magnetic dampers are provided at different positions on the guide rail; further applied to an embodiment of the present invention, a plurality of cameras may be provided at different positions outside the elevator car or outside the guide rail frame;
[0054] The magnetic damper is used to slow down the descent of the elevator car. It can be a number of different induction coils, each of which is equipped with an electromagnet. The electromagnet generates a magnetic field, and the descending elevator car cuts the magnetic flux of the magnetic field. The historical magnetic flux passing through is changing, and the descending elevator car is subjected to electromagnetic damping, that is, it is subjected to upward resistance, which slows down the descent of the car.
[0055] In an embodiment of the present invention, historical weight data in the elevator car can be obtained, that is, the control device may include a storage device, which can store weight data carried on multiple elevator cars; that is, the historical weight data refers to the weight data carried on the elevator car within a preset time period in the past.
[0056] Step S102: obtaining the historical induced current and historical magnetic flux of the magnetic damper;
[0057] Further applied to the embodiments of the present invention, the historical induced current and historical magnetic flux of multiple magnetic dampers set at different positions of the guide rail can also be obtained; the historical induced current refers to the change in induced current generated when the magnetic damper is operating within a preset time period; the historical magnetic flux refers to the change in magnetic flux generated when the magnetic damper is operating within a preset time period; for example, the historical induced current can be: k1A, k2A, k3A, k4A, k5A, k6A, k7A, k8A, k9A; the historical magnetic flux can be: m1Wb, m2Wb, m3Wb, m4Wb, m5Wb, m7Wb, m8Wb, m9Wb, m10Wb.
[0058] Step S103: establishing a corresponding relationship between the historical weight data, the historical induced current, and the historical magnetic flux;
[0059] After the historical weight data, the historical induced current, and the historical magnetic flux are acquired, a corresponding relationship among the historical weight data, the historical induced current, and the historical magnetic flux may be further established.
[0060] In a specific example of an embodiment of the present invention, establishing the correspondence between the historical weight data, historical induced current and historical magnetic flux includes: obtaining weight current data corresponding to the historical weight data; establishing a first correspondence between the weight current and the historical induced current; and establishing a second correspondence between the weight current and the historical magnetic flux.
[0061] In an embodiment of the present invention, weight data can first be converted into weight current data; the weight current data is the current data generated by the weight sensor when the corresponding weight data is measured, and the two have a corresponding relationship. Converting weight data into current data can improve the efficiency of model training; in addition, a first corresponding relationship between weight current and historical induced current can be established, that is, the weight current of the weight sensor and the historical induced current of the magnetic damper at the same time can be summarized and associated; in addition, a second corresponding relationship between the weight current and the historical magnetic flux is also established, that is, the weight current of the weight sensor and the historical magnetic flux of the magnetic damper at the same time can be summarized and associated.
[0062] Step S104: generating a weight-current fitting curve for home elevator maintenance according to the corresponding relationship;
[0063] Specifically applied to the embodiment of the present invention, after obtaining the first corresponding relationship between the weight current and the historical induced current and the second corresponding relationship between the weight current and the historical magnetic flux, a weight current fitting curve for home elevator maintenance can be generated according to the above corresponding relationships. Specifically, generating the weight current fitting curve for home elevator maintenance according to the corresponding relationships includes:
[0064] Fitting the data in the first corresponding relationship according to the vertical and horizontal coordinates to generate a first weight-current fitting curve for home elevator maintenance;
[0065] The data in the second corresponding relationship is fitted according to the vertical and horizontal coordinates to generate a second weight-current fitting curve for home elevator maintenance.
[0066] Specifically, the weight current in the first corresponding relationship is taken as the X-axis and the historical induced current is taken as the Y-axis, and the first weight current fitting curve of the home elevator maintenance is generated by fitting; in addition, the weight current in the first corresponding relationship is taken as the X-axis and the historical magnetic flux is taken as the Y-axis, and the second weight current fitting curve of the home elevator maintenance is generated by fitting. The corresponding data is smoothed by fitting to improve the efficiency of the model input and output.
[0067] Regarding the fitting method, the embodiment of the present invention can also perform fitting through various methods such as linear regression, quadratic regression, nonlinear least squares fitting, spline interpolation, etc., and the embodiment of the present invention does not impose too many restrictions on this.
[0068] Step S105: establishing a specific model according to the plurality of weight-current fitting curves;
[0069] After obtaining the first weight current fitting curve and the second weight current fitting curve, a specific model is established based on the weight current fitting curve. The specific model is established based on multiple weight current fitting curves, including: extracting metadata corresponding to the first weight current fitting curve and the second weight current fitting curve, associating the metadata with historical fault information to form associated data, and converting the associated data into training set data; inputting the training set data into the artificial intelligence model for training to obtain a trained artificial intelligence model.
[0070] In actual application in the embodiments of the present invention, historical fault information may be fault information occurring in an elevator car, for example, "the elevator car stalled in a certain period of time" or "the elevator car stopped lifting or decreasing in a certain period of time"; the above historical fault information is combined with weight current, historical induced current or weight current, and historical magnetic flux to be associated as training set data. Furthermore, the specific model may include multiple neural network models, and the training set data is input into the artificial intelligence model for training, and the model parameters are adjusted until the iteration is completed to obtain a trained artificial intelligence model.
[0071] In an embodiment of the present invention, the loss function M of the artificial intelligence model is: Where N is the number of samples in the training set, φ is the magnetic flux in the training set, A is the mean of the induced current and weight current in the training set, and y i is the predicted value of sample i. By combining the loss function with the magnetic flux and current data, the accuracy of the function is effectively improved.
[0072] Regarding the type of neural network model, it can be multiple types of supervised neural network models, such as convolutional neural networks, recursive neural networks, etc., and an unsupervised neural network model can also be used to implement the functions of the embodiment of the present invention. It is only necessary to obtain the data to be input into the model. The unsupervised neural network model can include a K-means algorithm model, a hierarchical clustering algorithm model, a PCA principal component analysis model, etc. The embodiment of the present invention does not impose too many restrictions on this.
[0073] That is, in another embodiment, an unsupervised neural network model is used as the initial model, and data of multiple weight-current fitting curves are input into the unsupervised neural network model to obtain output first fault information, which can be predicted fault information.
[0074] Step S106: receiving a maintenance request for the elevator car and the guide rail, querying the specific model, obtaining first fault information, and determining the first fault information as a maintenance result;
[0075] Step S107: Output the inspection result.
[0076] Specifically applied to the embodiment of the present invention, after obtaining the trained artificial intelligence model and receiving the maintenance request for the elevator car and guide rail, the current car weight information and the corresponding induced current information, etc., can be input into the trained artificial intelligence model to predict the fault information, that is, to obtain the first fault information.
[0077] In an embodiment of the present invention, the elevator car and guide rails are provided with a plurality of cameras; the method further comprises: upon receiving a maintenance request for the elevator car and guide rails, obtaining a plurality of elevator images taken by the camera within a preset time period; performing abnormal feature comparison on the plurality of elevator images to obtain second fault information, and calculating a speed exceeding a threshold value based on the moving distance between image pixels, determining whether the car speed is too high, and identifying whether the appearance of the hardware device is damaged based on the image edge.
[0078] In actual application, the method also includes: matching the first fault information with the second fault information to obtain comprehensive fault information of the home elevator; that is, the comprehensive fault information can be a combination of predicted software fault information and hardware component appearance damage information. Finally, the maintenance result can be output. For example, the maintenance result can display: "The elevator may stall, please suspend use and contact professional maintenance personnel in time", or "A certain component of the elevator may be damaged, please contact professional maintenance personnel in time."
[0079] In an embodiment of the present invention, the home elevator includes an elevator car and a guide rail; a plurality of magnetic dampers are provided at different positions of the guide rail; the method includes: obtaining historical weight data in the elevator car; obtaining historical induced current and historical magnetic flux of the magnetic damper; establishing a correspondence between the historical weight data, historical induced current and historical magnetic flux; generating a weight current fitting curve for home elevator maintenance based on the correspondence; establishing a specific model based on multiple weight current fitting curves; receiving a maintenance request for the elevator car and guide rail, querying the specific model, obtaining first fault information, and determining the first fault information as the maintenance result; outputting the maintenance result; inputting the above-mentioned weight information and corresponding induced current information into the trained artificial intelligence model to predict fault information; being able to accurately predict elevator stall problems, improve the durability of elevator buffers, improve elevator quality control, and ensure the safety of carried users.
