[0056] The following reference Figure 1 This invention describes a method for monitoring the safe operation of an elevator based on power line carrier communication, provided by some embodiments of the present invention.

[0057] like Figure 1 As shown, one embodiment of the present invention provides a method for monitoring the safe operation of an elevator based on power line carrier, comprising: acquiring sample elevator data (including but not limited to basic attribute data, historical working data, historical fault data, historical maintenance data, historical monitoring data, etc. of the sample elevator), sample building data of the building in which the sample elevator is installed (including but not limited to building drawing data, building 3D point cloud data, building power supply data, building internal power consumption data, etc.), sample environmental data of the environment in which the sample elevator is located (including but not limited to temperature data, weather data, air humidity data, air circulation data, etc.), and sample user data of the users of the sample elevator (including but not limited to user basic information, user elevator usage habits, user elevator usage frequency, user elevator usage method, etc.).

[0058] Based on the sample elevator data, the sample building data, the sample environment data, and the sample user data, establish a first elevator monitoring model (the first elevator monitoring model includes, but is not limited to, determining the key components of the elevator to be monitored and the monitoring methods based on elevator type, elevator working status, building characteristics, environmental characteristics, user characteristics, etc.) and a first elevator data management model (the first elevator data management model includes, but is not limited to, data acquisition methods, data preprocessing methods, data encryption methods, data storage methods, data transmission methods, etc.).

[0059] The first monitoring data is obtained by monitoring the intelligent elevator according to the first elevator monitoring model;

[0060] The first monitoring data is managed according to the first elevator data management model.

[0061] It is understood that, in this embodiment, the steps of establishing the first elevator monitoring model and the first elevator data management model based on the sample elevator data, the sample building data, the sample environmental data, and the sample user data include:

[0062] Build a basic monitoring model;

[0063] The sample elevator data (including but not limited to basic attribute data, historical working data, historical fault data, historical maintenance data, historical monitoring data, etc.), sample building data (including but not limited to building drawing data, building 3D point cloud data, building power supply data, building internal power consumption data, etc.), sample environmental data (including but not limited to temperature data, weather data, air humidity data, air circulation data, etc.), and sample user data (including but not limited to user basic information, user elevator usage habits, user elevator usage frequency, user elevator usage methods, etc.) are cleaned and integrated to extract the features required for monitoring.

[0064] Using a basic monitoring model, based on domain knowledge and historical elevator fault data, the key features most relevant to elevator safe operation are selected from the features required for monitoring, including elevator type, elevator structure, elevator working status, building features, environmental features, and user features.

[0065] Using a basic monitoring model, we analyze vulnerable components and potential risks under different elevator types and user conditions to determine the target monitoring areas.

[0066] Using a basic monitoring model, determine the corresponding sensors / acquisition terminals and information acquisition / monitoring methods for different target locations;

[0067] Using a basic monitoring model and the association rule method, determine the optimal monitoring strategy under given conditions;

[0068] An improved monitoring model is obtained through the above learning and training.

[0069] Test data was used to verify the effectiveness of the improved monitoring model, and new data was used to continuously optimize the model, resulting in the first elevator monitoring model (this model, which integrates multi-source heterogeneous data, can realize the formulation of intelligent monitoring strategies for individual elevators).

[0070] Build a basic data management model;

[0071] Using a basic data management model, the optimal data collection method for different types of data is determined based on factors such as elevator structure, sensor acquisition terminal layout, and user usage.

[0072] Based on the basic data management model, a preprocessing workflow is designed according to the data format, acquisition frequency, etc., including operations such as cleaning, noise reduction, and synchronization.

[0073] By utilizing a basic data management model, and based on factors such as data sensitivity, environmental conditions, and regulatory requirements, appropriate encryption algorithms are selected to ensure the security of transmission and storage.

[0074] Using a basic data management model, and considering factors such as data type and access frequency, different data storage methods can be selected (such as relational databases or non-relational databases, local storage or server storage, distributed storage, etc.).

[0075] Using a basic data management model, determine the data transmission channel and transmission method based on network conditions, real-time requirements, etc.

[0076] The improved data management model is obtained through the above learning and training;

[0077] The effectiveness of the improved data management model was verified using test data, and the model was continuously optimized using new data to obtain the first elevator data management model.

[0078] Continuously optimize the data management model based on new data and environmental changes.

[0079] By building an intelligent data management model, the problem of managing massive amounts of heterogeneous data in elevator systems can be effectively solved.

[0080] The technical solution of this embodiment involves acquiring sample elevator data, sample building data of the building where the sample elevator is installed, sample environment data of the environment in which the sample elevator is located, and sample user data of the users of the sample elevator. Based on the sample elevator data, sample building data, sample environment data, and sample user data, a first elevator monitoring model and a first elevator data management model are established. The intelligent elevator is monitored using the first elevator monitoring model to obtain first monitoring data. The first monitoring data is then managed using the first elevator data management model. This invention not only provides intelligent, personalized, and accurate elevator monitoring solutions but also efficiently manages the monitoring data.

[0081] In some possible embodiments of the present invention, the step of monitoring the intelligent elevator according to the first elevator monitoring model to obtain the first monitoring data includes:

[0082] The system acquires the following data: first elevator data (including but not limited to basic attribute data, historical working data, historical fault data, historical maintenance data, historical monitoring data, etc. of the sample elevator), first building data of the building (including but not limited to building drawing data, building 3D point cloud data, building power supply data, building internal power consumption data, etc.), first environmental data of the environment (including but not limited to temperature data, weather data, air humidity data, air circulation data, etc.), and first user data of the smart elevator (including but not limited to user basic information, user elevator usage habits, user elevator usage frequency, user elevator usage method, etc.).

[0083] A first elevator monitoring scheme is determined from the first elevator monitoring model based on the first elevator data, the first building data, the first environmental data, and the first user data.

[0084] Based on the first elevator monitoring scheme, the first monitoring object (such as the target part), the first monitoring device (such as the sensor, the acquisition terminal, etc.) corresponding to the first monitoring object, and the first data monitoring method (such as determining different monitoring cycles, data acquisition methods, etc.) in the intelligent elevator are determined.

[0085] The first monitoring device is controlled to monitor the first monitoring object in the first data monitoring method to obtain the first monitoring data.

[0086] It is understandable that by acquiring current data related to the smart elevator and combining it with the first elevator monitoring model to determine the first elevator monitoring scheme, the accuracy and timeliness of the monitoring scheme can be guaranteed, thus improving monitoring efficiency.

[0087] In some possible embodiments of the present invention, the step of managing the first monitoring data according to the first elevator data management model includes:

[0088] Based on the first elevator data management model, determine the data type, data volume, data importance level, and data susceptibility to interference of the first monitoring data;

[0089] Based on the data type, data volume, data importance level, and data susceptibility to interference, determine the first data preprocessing method, first data encryption method, first data storage method, and first data transmission method corresponding to the first monitoring data;

[0090] The first monitoring data is managed according to the first data preprocessing method, the first data encryption method, the first data storage method, and the first data transmission method.

[0091] Understandably, in order to ensure efficient and accurate data management, in this embodiment, the data type, data volume, data importance level, and data susceptibility to interference of the first monitoring data are determined according to the first elevator data management model; a first data preprocessing method, a first data encryption method, a first data storage method, and a first data transmission method are determined according to the data type, the data volume, the data importance level, and the data susceptibility to interference of the first monitoring data; and the first monitoring data is managed according to the first data preprocessing method, the first data encryption method, the first data storage method, and the first data transmission method.

[0092] In some possible embodiments of the present invention, the step of managing the first monitoring data according to the first data preprocessing method, the first data encryption method, the first data storage method, and the first data transmission method includes:

[0093] The first monitoring data is cleaned and integrated according to the first preprocessing method, effective features are extracted, and a unified format analysis dataset is generated to obtain the second monitoring data.

[0094] The second monitoring data is labeled with data type tags, data importance level tags, and data susceptibility to interference tags to obtain the third monitoring data;

[0095] Based on the data type label, the data importance level label, and the data susceptibility to interference label, and according to the first encryption method, the corresponding encryption algorithm is selected to encrypt the third monitoring data to obtain the fourth monitoring data;

[0096] The fourth monitoring data is stored according to the first data storage method, and a first copy of the fourth monitoring data is created;

[0097] The first copy is transmitted according to the first data transmission method.

[0098] It is understandable that, in order to further improve the efficiency of data management, in this embodiment, the first data preprocessing method, the first data encryption method, the first data storage method, and the first data transmission method are used to manage the monitoring data.

[0099] In some possible embodiments of the present invention, the step of transmitting the first copy according to the first data transmission method includes:

[0100] Establish a data transmission channel status assessment model;

[0101] Based on the data transmission channel status evaluation model, the power line carrier communication channel is evaluated from several dimensions, including transmission rate, transmission stability, anti-interference, and security, to obtain first evaluation data; the first auxiliary communication channel is evaluated to obtain second evaluation data; and the second auxiliary communication channel is evaluated to obtain third evaluation data.

[0102] Based on the data type label, the data importance label, the data susceptibility to interference label, the first evaluation data, the second evaluation data, and the third evaluation data, the first copy is segmented, and a first data transmission channel is dynamically selected from the power line carrier communication channel, the first auxiliary communication channel, and the second auxiliary communication channel for data transmission.

[0103] Understandably, in order to ensure efficient and secure data transmission, in this embodiment, a data transmission channel status evaluation model is established. Based on the data transmission channel status evaluation model, a comprehensive weighting is performed on the power line carrier communication channel from several dimensions, including transmission rate, transmission stability, anti-interference, and security (the weighting coefficients can be dynamically adjusted according to the actual needs of data transmission) to obtain first evaluation data, second evaluation data for the first auxiliary communication channel, and third evaluation data for the second auxiliary communication channel.

[0104] Based on the data type label, the data importance level label, the data susceptibility label, the first evaluation data, the second evaluation data, and the third evaluation data, the first copy is segmented to obtain multiple data segmentation groups. These groups are divided according to one or more dimensions of the data type label, the data importance level label, and the data susceptibility label, and are matched with one of the first evaluation data, the second evaluation data, or the third evaluation data (i.e., matching the communication capability / security / stability, etc. of the communication channel corresponding to the evaluation data). A first data transmission channel is dynamically selected from the power line carrier communication channel, the first auxiliary communication channel, and the second auxiliary communication channel (for each data segmentation group) for data transmission.

[0105] In this embodiment, a data transmission channel status evaluation model can be established using the following method:

[0106] Select key indicators that can reflect the channel status, such as signal power, noise power, bit error rate, latency jitter, packet loss rate, etc.

[0107] Based on the quantitative range and importance of each key indicator, a scoring standard is established, that is, a score range is set for each key indicator.

[0108] By employing methods such as index weighting, grey evaluation, and neural networks, and combining the scores of various key indicators, an overall assessment value for the channel's status is obtained.

[0109] Based on the overall channel status assessment value, multiple status ranges for transmission quality are set, such as good, average, poor, and very poor.

[0110] A large amount of historical sample data was collected during the historical data transmission process. Machine learning methods were used to train and optimize the evaluation model so that it could dynamically adapt to changes in the communication environment, thus obtaining a data transmission channel status evaluation model.

[0111] In some possible embodiments of the present invention, corresponding control strategies can also be mapped according to different states of the data transmission channel, such as controlling power, changing the transmission rate, and selecting a backup channel.

[0112] In this embodiment, through scientific model design and big data-driven optimization, real-time monitoring and intelligent evaluation of power line carrier communication quality can be achieved.

[0113] In some possible embodiments of the present invention, the operation of evaluating the power line carrier communication channel to obtain first evaluation data includes:

[0114] According to preset rules, the original node, the first node, the second node, the third node, and the last node are determined on the power line carrier communication channel;

[0115] During the transmission of the same historical data, historical node monitoring data is obtained by monitoring the original node, the first node, the second node, the third node, and the last node, and the transmission status data at these nodes is obtained from the historical node monitoring data.

[0116] By comparing and analyzing the transmission status data, a data noise impact model for the power line carrier communication channel is established.

[0117] Based on the data transmission channel status assessment model and the data noise impact model, the power line carrier communication channel is comprehensively weighted from several dimensions, including transmission rate, transmission stability, anti-interference, and security, to obtain the first assessment data.

[0118] Understandably, in order to accurately evaluate power line carrier communication channels, the following methods can be used to set up various monitoring nodes for the power line carrier communication channel during data transmission:

[0119] Original node: Identify the data sources that need to be monitored inside the elevator, such as the equipment or sensors that acquire data on elevator operation status, alarm information, video surveillance, etc., and use them as the original node.

[0120] First node: A power line carrier modulation module is installed inside the elevator car. It collects data from the original node, modulates it into a power line carrier signal, and sends it to the power line. This module can be identified as the first node.

[0121] The second node: A power line carrier demodulation module can be installed in the power distribution box at the elevator entrance on each floor to obtain elevator monitoring data from the power line and demodulate the raw data, which is then used as the second node.

[0122] The third node: A centralized data receiving device is set up in the elevator machine room, which is connected to the power line carrier demodulation module corresponding to each power line and aggregates the monitoring data of elevators on each floor. This can be regarded as the third node.

[0123] The final node: The power line carrier signal receiving and parsing processing device in the monitoring center obtains the monitoring information of each elevator and each floor, serving as the final node for data transmission.

[0124] More relay nodes can be set up as needed to expand network coverage.

[0125] In this embodiment, by clearly defining the data generation source, transmission path, and processing endpoint, and setting up corresponding monitoring mechanisms, it is helpful to build a reliable power line carrier monitoring network, which can accurately evaluate the power line carrier communication channel and ensure the real-time transmission of elevator operation information.

[0126] In some possible embodiments of the present invention, the step of comparing and analyzing the transmission status data to establish a data noise impact model for the power line carrier communication channel includes:

[0127] Extract signal quality metrics (such as signal-to-noise ratio, bit error rate, phase-locked state, etc.) and environmental noise data (such as noise type, frequency range, amplitude, etc.) from the transmission status data of the channel.

[0128] Preprocessing such as correction, synchronization, and interpolation is performed on signal quality index data and environmental noise data to align them onto the same time series.

[0129] Statistical analysis methods, such as correlation coefficient analysis and regression analysis, are used to determine the correlation analysis results between signal quality index data and environmental noise data;

[0130] Based on the correlation analysis results, linear regression, nonlinear regression, neural network and other methods are used to establish a model of the impact of noise factors on channel quality indicators.

[0131] The model's effectiveness was verified using newly collected transmission status data and noise data. Based on the verification results, the model was optimized to obtain the data noise impact model.

[0132] This data-driven noise impact model can identify the root causes of power line carrier communication quality problems and guide noise reduction optimization measures.

[0133] In some possible embodiments of the present invention, the step of evaluating the power line carrier communication channel to obtain the first evaluation data by comprehensively weighting the data transmission channel status evaluation model and the data noise impact model from several dimensions such as transmission rate, transmission stability, anti-interference, and security includes:

[0134] Based on the quantitative indicators of various evaluation dimensions such as transmission rate, transmission stability, anti-interference, and security, the scoring range and standards are determined (e.g., a maximum score of 10 points).

[0135] Determine the weight of each evaluation dimension (e.g., transmission stability 50%, interference resistance 30%);

[0136] Based on the data transmission channel status assessment model and the data noise impact model, calculate the score result for each assessment dimension;

[0137] The scores for each evaluation dimension are weighted and summed according to the determined weights to obtain the comprehensive evaluation score of the power line carrier communication channel.

[0138] Based on the comprehensive evaluation score, the overall channel quality level is determined, and the channel quality level is determined when one of the following is the primary dimension: transmission rate, transmission stability, anti-interference, and security, and the others are secondary dimensions.

[0139] In this embodiment, by considering various influencing factors from multiple perspectives, a more comprehensive and accurate evaluation of power line carrier communication quality can be achieved.

[0140] It is understood that the method for evaluating the first auxiliary communication channel to obtain the second evaluation data and the method for evaluating the second auxiliary communication channel to obtain the third evaluation data are based on the same principle as the method in this embodiment. They are only adapted to the differences between the first or second auxiliary communication channel and the power line carrier communication channel (such as differences in transmission protocols). The present invention does not limit this.

[0141] In some possible embodiments of the present invention, it further includes:

[0142] When the power line carrier communication channel is performing a data transmission task, it obtains the load power requirements of the load powered by the power line carrier communication channel and the data transmission power requirements of the data transmitted through the power line carrier communication channel.

[0143] Based on the load power requirements and the data transmission power requirements, determine whether the power line carrier communication channel can simultaneously meet the load power requirements and data transmission requirements;

[0144] If the requirement cannot be met, the data transmission task of the power line carrier communication channel will be assigned to the first auxiliary communication channel or the second auxiliary communication channel.

[0145] It is understandable that power line carrier communication channels reuse power lines. When the power lines bear heavy power transmission loads, problems may arise in the execution of data transmission tasks. In this embodiment, when the power line carrier communication channel is performing a data transmission task, it obtains the load power requirements of the load powered by the power line carrier communication channel and the data transmission power requirements for data transmitted through the power line carrier communication channel. Based on the load power requirements and the data transmission power requirements, it determines whether the power line carrier communication channel can simultaneously meet the load power requirements and data transmission requirements. If it cannot, the data transmission task of the power line carrier communication channel is allocated to the first auxiliary communication channel or the second auxiliary communication channel, which can effectively reduce the pressure on the power line carrier communication channel and ensure its safety.

[0146] In some possible embodiments of the present invention, the step of segmenting the first copy according to the data type label, the data importance level label, the data susceptibility label, the first evaluation data, the second evaluation data, and the third evaluation data, and dynamically selecting a first data transmission channel from the power line carrier communication channel, the first auxiliary communication channel, and the second auxiliary communication channel for data transmission includes:

[0147] The first copy is grouped according to its importance level based on the data importance level label to obtain a data subset;
