Technical Field
[0001] This application relates to the field of signal transmission technology, specifically to a wireless signal transmission control method and system for an elevator. Background Technology
[0002] Elevators are primarily used in various high-rise and super high-rise buildings in cities. In traditional elevator applications, signals are transmitted from the ground end via a traveling cable. However, this method is unsuitable for elevators used in special environments, such as inclined rail elevators and elevators operating in high winds. Therefore, these elevators employ wireless signal transmission from the ground end. However, wireless signal transmission is susceptible to interference, resulting in poor signal transmission between the ground end and the elevator.
[0003] Therefore, how to reduce interference with wireless signal transmission during the application of elevators has become an urgent technical problem to be solved. Summary of the Invention

[0030] This application provides a wireless signal transmission control method for an elevator, applied in a server. (Refer to...) Figure 1 This document illustrates a flowchart of a wireless signal transmission control method for an elevator according to an embodiment of this application. The method includes steps S1-S5, as follows:
[0031] Step S1: Obtain the transmission performance score corresponding to each current wireless signal transmission scheme.
[0032] Specifically, in this technical solution, the current wireless signal transmission scheme includes the current video signal transmission scheme, the current telephone voice signal transmission scheme, and the current control signal transmission scheme.
[0033] Before obtaining the transmission performance scores for each current wireless signal transmission scheme, it is first necessary to evaluate the transmission quality of various types of signals.
[0034] For video signals, the transmission quality needs to be evaluated by considering factors such as resolution, frame rate, latency, and frame drop rate. For example, the magnitude of latency and frame drop rate affects the smoothness and reliability of the video.
[0035] For telephone voice signals, the transmission quality needs to be evaluated by considering metrics such as signal-to-noise ratio (SNR), latency, and packet loss rate. For example, the SNR directly affects the clarity of the call, while latency and packet loss rate affect the smoothness and reliability of the call.
[0036] For control signals, the transmission quality needs to be evaluated by considering indicators such as real-time performance, reliability, and accuracy.
[0037] After evaluating the transmission quality of various signals, it is necessary to calculate the corresponding transmission performance score based on the evaluation results. The following embodiments will describe in detail the specific steps for calculating the transmission performance score.
[0038] In one possible implementation, prior to step S1, the method further includes calculating a transmission performance score.
[0039] In one possible implementation, calculating the transmission performance score specifically includes the following steps:
[0040] Determine multiple first wireless signal transmission indicators corresponding to the current video signal transmission scheme, and obtain multiple first wireless signal transmission data based on the multiple first wireless signal transmission indicators.
[0041] Specifically, in this technical solution, for wireless signal transmission, especially video signal transmission, several key performance indicators directly affect transmission quality. These indicators include, but are not limited to, signal strength, bandwidth utilization, latency, frame drop rate, and signal stability. Determining and analyzing these indicators is crucial for evaluating the effectiveness of current video signal transmission solutions.
[0042] Next, the specific implementation steps involve obtaining multiple sets of initial wireless signal transmission data. This requires the use of specialized monitoring tools and analysis software to monitor the video signal transmission in real time. For example, network analyzers can be used to measure signal strength and bandwidth utilization, latency testing tools can be used to measure signal transmission time delay, and packet analysis tools can be used to monitor frame drop rate and signal stability. The data collected through these tools will provide quantified metrics for each indicator.
[0043] A first transmission score is obtained based on multiple first wireless signal transmission data.
[0044] Specifically, in this technical solution, the first step involves comprehensively analyzing and processing the data collected in the aforementioned steps regarding the first wireless signal transmission indicators, such as signal strength, bandwidth utilization, latency, frame drop rate, and signal stability. These indicators are typically quantified values that can be directly used to calculate scores. The score calculation requires a standardized method; for example, different weights can be assigned to each indicator based on its importance in the overall video transmission quality, and then a weighted average is calculated based on these weights for the actual measured values of each indicator. This weighting method not only ensures the accuracy of the score but also reflects the actual impact of each indicator on the video signal transmission quality.
[0045] Determine multiple second wireless signal transmission indicators corresponding to the current telephone voice signal transmission scheme, and obtain multiple second wireless signal transmission data based on the multiple second wireless signal transmission indicators.
[0046] Specifically, in this technical solution, this step involves accurately quantifying the transmission characteristics of telephone voice signals in order to objectively evaluate their performance. This includes, but is not limited to, collecting data on key performance indicators of the voice signal such as signal-to-noise ratio, latency, packet loss rate, and clarity. Precise measurement of these indicators can be achieved through various communication testing equipment and analysis software, which can monitor the quality of the voice signal in real time and provide quantitative data.
[0047] A second transmission score is obtained based on multiple second wireless signal transmission data.
[0048] Specifically, this technical solution first calculates and evaluates metrics such as latency and packet loss rate. This is achieved using various communication performance analysis tools to provide accurate measurements. Next, these metrics are converted into scores. This is done by setting performance thresholds for each metric and calculating a second transmission score based on the actual measured values' performance relative to these thresholds. For example, latency below a certain preset value results in a higher score, while high latency leads to a lower score.
[0049] Determine multiple third wireless signal transmission indicators corresponding to the current control signal transmission scheme, and obtain multiple third wireless signal transmission data based on these multiple third wireless signal transmission indicators.
[0050] Specifically, in this technical solution, control signals differ from video or audio signals. They typically require extremely high reliability and extremely low latency to ensure the accurate transmission of real-time control commands. Therefore, determining key performance indicators such as signal stability, response time, and packet loss rate, and evaluating the current control signal transmission scheme accordingly, is crucial for maintaining the normal operation of the entire system.
[0051] Next, the specific implementation steps involve obtaining multiple third-party wireless signal transmission data. Specialized monitoring tools and software are needed to monitor the transmission quality of the control signals in real time. These include using a network analyzer to assess signal stability, using latency testing instruments to measure the response time of the control signals, and using packet capture tools to monitor packet loss. These tools not only provide real-time data for various indicators but also accurately measure the performance of the control signal transmission.
[0052] A third transmission score is obtained based on multiple third-party wireless signal transmission data.
[0053] Specifically, this technical solution first quantifies key performance indicators such as signal stability, response time, and packet loss rate. This is achieved by using advanced data processing and analysis techniques, such as statistical analysis or machine learning algorithms, to extract meaningful information from the collected data. Each performance indicator is assigned a different weight based on its importance in control signal transmission, and a comprehensive third transmission score is calculated accordingly.
[0054] Based on the first transmission score, the second transmission score, and the third transmission score, a transmission performance score is calculated.
[0055] Specifically, in this technical solution, the performance of the entire wireless signal communication system is comprehensively evaluated by calculating a transmission effect score, including the transmission effects of video signals, telephone voice signals, and control signals.
[0056] In one possible implementation, a transmission performance score is calculated based on a first transmission score, a second transmission score, and a third transmission score, specifically including the following steps:
[0057] The transmission performance score is calculated using the following formula:
[0058] Y = αy1 + βy2 + γy3;
[0059] Where Y is the transmission performance score, y1 is the first transmission score, y2 is the second transmission score, y3 is the third transmission score, α is the first influence weight, β is the second influence weight, and γ is the third influence weight.
[0060] Specifically, in this technical solution, α + β + γ = 1. The values of the first influence weight, the second influence weight, and the third influence weight will be set based on the specific requirements and performance objectives of the system.
[0061] Step S2: When the transmission effect score is less than the preset transmission effect score, determine multiple environmental influencing factors.
[0062] Specifically, in this technical solution, when the transmission performance score is lower than a preset value, it indicates the presence of unfavorable environmental conditions that may interfere with or weaken the transmission of wireless signals to varying degrees. Therefore, it is necessary to identify these environmental factors to understand the reasons for poor transmission performance. These environmental factors include temperature, humidity, electromagnetic interference, wind force, and obstacle density.
[0063] Step S3: Obtain a comprehensive environmental impact score based on multiple environmental impact factors.
[0064] Specifically, in this technical solution, the server will comprehensively evaluate multiple environmental impact factors such as temperature, humidity, electromagnetic interference, wind force, and obstacle density to obtain a comprehensive environmental impact score.
[0065] In one possible implementation, step S3 specifically includes the following steps:
[0066] Acquire multiple temperature detection data, multiple humidity detection data, multiple electromagnetic interference detection data, multiple wind force detection data, and multiple obstacle densities within a preset time period.
[0067] Specifically, this technical solution first uses various sensors and monitoring devices to measure temperature, humidity, electromagnetic field strength, wind speed, and the density of potential physical obstacles in the environment. The collection of this data should cover the entire operational range of the transmission system to ensure a comprehensive assessment of the environmental impact.
[0068] For temperature, multiple temperature data points can be measured within a preset time period using a temperature sensor; for humidity, multiple humidity data points can be measured within a preset time period using a humidity sensor; for electromagnetic interference, multiple electromagnetic interference data points can be measured within a preset time period using an electromagnetic field strength measuring device; for wind, multiple wind force data points can be measured within a preset time period using devices such as anemometers; and for obstacle density, obstacle density data, including the number, size, and distribution of obstacles, can be collected within a preset time period using detection devices such as laser scanners and cameras.
[0069] The server will then acquire multiple temperature detection data, multiple humidity detection data, multiple electromagnetic interference detection data, multiple wind force detection data, and multiple obstacle density data within a preset time period. The preset time period is preferably the 30 minutes preceding the current time.
[0070] Multiple temperature measurement data are normalized to obtain normalized temperature values.
[0071] Specifically, in this technical solution, since the elevator's height changes during use, temperature measurement data from different locations may vary. For example, differences in height and sunlight conditions can affect the accurate assessment of temperature impact. Normalization transforms this data to a common standard scale, ensuring comparability and consistency between data. The server performs statistical analysis on the collected temperature data, identifying the data range, including the highest and lowest temperatures. Then, a normalization formula is applied to convert each temperature value into a value between 0 and 1. Normalized temperature value = (Actual temperature value - Lowest temperature) / (Highest temperature - Lowest temperature). Normalization is then applied to multiple humidity measurement data to obtain normalized humidity values.
[0072] Specifically, in this technical solution, because the elevator's height changes during use, humidity measurement data from different locations may vary, potentially affecting the accurate assessment of humidity impact. Normalization transforms this data to a common standard scale, ensuring comparability and consistency between data points. The server performs statistical analysis on the collected humidity data, identifying the data range, including the highest and lowest humidity levels. Then, a normalization formula is applied to convert each humidity value into a value between 0 and 1. Normalized humidity value = (Actual humidity value - Lowest humidity) / (Highest humidity - Lowest humidity).
[0073] Multiple electromagnetic interference detection data are normalized to obtain normalized electromagnetic interference values.
[0074] Specifically, in this technical solution, due to changes in height during elevator operation and the influence of other electronic equipment and power lines, electromagnetic interference (EMI) detection data may differ at different locations. These differences may affect the accurate assessment of EMI impact. Normalization transforms this data to a common standard scale, ensuring comparability and consistency between data. The server performs statistical analysis on the collected EMI data, identifying the data range, including the highest and lowest EMI values. Then, a normalization formula is applied to convert each EMI value into a value between 0 and 1. Normalized EMI value = (Actual EMI value - Lowest EMI value) / (Highest EMI value - Lowest EMI value).
[0075] Multiple wind force detection data are normalized to obtain normalized wind force values.
[0076] Specifically, in this technical solution, because the elevator's height changes during use, wind speed data from different locations may vary. Factors such as different heights and open spaces can affect the accurate assessment of wind impact. Normalization transforms this data to a common standard scale, ensuring comparability and consistency. The server performs statistical analysis on the collected wind data, identifying the data range, including the highest and lowest wind speed values. Then, a normalization formula is applied to convert each wind speed value into a value between 0 and 1. Normalized wind speed value = (Actual wind speed value - Lowest wind speed value) / (Highest wind speed value - Lowest wind speed value).
[0077] The densities of multiple obstacles are normalized to obtain normalized density values.
[0078] Specifically, in this technical solution, because the elevator's height changes during use, obstacle density detection data may differ at different locations. For example, the obstacle environment varies at different heights, and these differences may affect the accurate assessment of the impact on obstacle density. Normalization transforms this data to a common standard scale, ensuring comparability and consistency between data. The server performs statistical analysis on the collected obstacle density data, identifying the data range, including the highest and lowest obstacle density values. Then, a normalization formula is applied to convert each obstacle density value into a value between 0 and 1. Normalized obstacle density value = (Actual obstacle density value - Lowest obstacle density value) / (Highest obstacle density value - Lowest obstacle density value).
[0079] The comprehensive environmental impact score is calculated based on normalized temperature, normalized humidity, normalized electromagnetic interference, normalized wind speed, and normalized density values.
[0080] Specifically, in this technical solution, the server will calculate the comprehensive environmental impact score based on normalized temperature, normalized humidity, normalized electromagnetic interference, normalized wind speed, and normalized density values.
[0081] In one possible implementation, a comprehensive environmental impact score is calculated based on normalized temperature, normalized humidity, normalized electromagnetic interference, normalized wind speed, and normalized density values, specifically including the following steps:
[0082] The comprehensive environmental impact score is calculated using the following formula:
[0083]
[0084] Where X is the comprehensive environmental impact score, T is the normalized humidity value, H is the normalized electromagnetic interference value, E is the normalized electromagnetic interference value, W is the normalized wind speed value, O is the normalized density value, a is the first weighting factor, b is the second weighting factor, c is the third weighting factor, d is the fourth weighting factor, and w is the fifth weighting factor.
[0085] Specifically, in this technical solution, the transmission performance of wireless signals is affected not only by a single environmental factor but also by the combined effect of multiple factors. For example, high temperature and high humidity may jointly exacerbate signal attenuation, while increased electromagnetic interference and obstacle density may further reduce signal transmission efficiency. Therefore, by comprehensively considering the influence of these factors, the impact of the entire environment on wireless signal transmission can be assessed more accurately.
[0086] More specifically, the alun(1+T) part represents the effect of temperature on the wireless signal. Using the natural logarithm ln(1+T) on the temperature data is to simulate the nonlinear characteristics of the effect of temperature changes on the wireless signal. Since the effect of temperature on the wireless signal may increase significantly after a certain threshold, using a logarithmic function helps smooth out the effects of extreme values.
[0087] This section discusses the impact of humidity on wireless signals. It uses the square root function. This reflects the increasing trend of the impact of humidity changes on the signal, but the rate of increase in this impact slows down as humidity increases. It indicates that in high-humidity environments, the additional impact of each unit increase in humidity on the wireless signal gradually decreases.
[0088] ce -E This section represents the impact of electromagnetic interference on wireless signals. The exponential function e -E It is used to describe the negative impact of electromagnetic interference, that is, as electromagnetic interference increases, its interference effect on wireless signals increases exponentially.
[0089] dW 2 This section illustrates the impact of wind on wireless signals. The effect of wind is particularly significant for outdoor communications. Therefore, a square function W is used... 2 This reflects how the impact of wind on wireless signals increases dramatically with increasing wind speed.
[0090] The wsin(O) part represents the effect of obstacle density on the wireless signal. The sinusoidal function sin(O) is used to reflect the periodic or nonlinear effect of obstacles on the signal; for example, the signal may be more significantly affected under certain obstacle densities.
[0091] It should be noted that the values of the first, second, third, fourth, and fifth weighting factors will be set based on the specific requirements and performance goals of the system.
[0092] Step S4: Based on the transmission effect score and the comprehensive environmental impact score, adjust the current wireless signal communication scheme to obtain the adjusted wireless signal transmission scheme.
[0093] Specifically, in this technical solution, the server will comprehensively consider the transmission effect score and the comprehensive environmental impact score, and adjust the current wireless signal communication scheme to obtain an adjusted wireless signal transmission scheme.
[0094] In one possible implementation, step S4 specifically includes the following steps:
[0095] Based on the transmission performance score, calculate the first error rate between the transmission performance score and the preset transmission performance score.
[0096] Specifically, in this technical solution, by calculating the error rate between the current transmission effect and the preset standard, it is possible to quickly determine whether the actual performance of the signal transmission meets expectations, thereby determining whether further optimization or adjustment is needed. The first error rate = |(Current transmission effect score - Preset transmission effect score) / Preset transmission effect score| × 100%.
[0097] Based on the comprehensive environmental impact score, the second error rate between the comprehensive environmental impact score and the preset environmental impact score is calculated.
[0098] Specifically, in this technical solution, by calculating the second error rate, the actual impact of environmental conditions on transmission performance can be quantified, and it can be determined whether environmental adaptation adjustments to the signal transmission are necessary. Second error rate = |(Comprehensive environmental impact score - Preset environmental impact score) / Preset environmental impact score| × 100%.
[0099] When the first error rate and / or the second error rate are less than the preset error rate threshold, the current video signal transmission scheme is adjusted to obtain an adjusted video signal transmission scheme; the current telephone voice signal transmission scheme is adjusted to obtain an adjusted telephone voice signal transmission scheme; and the current control signal transmission scheme is adjusted to obtain an adjusted control signal transmission scheme.
[0100] Specifically, in this technical solution, the first step is to determine whether the current transmission scheme needs adjustment based on the first and second error rates calculated in the preceding steps. If either error rate exceeds a preset threshold, the direction and scope of adjustment need to be determined based on the specific circumstances of these scores.
[0101] In more detail, when video quality is low or high latency exists, it's necessary to increase bandwidth allocation; optimize or replace video compression coding techniques, using more efficient coding algorithms, such as H.265 instead of H.264. If latency is the primary issue, low-latency technologies and protocols should be used, and data buffering reduced to improve network processing capacity and speed. When video signal transmission is unstable, repeaters and amplifiers need to be added or optimized to increase signal coverage. This allows for adjustments to the current video signal transmission scheme, resulting in an optimized video signal transmission solution.
[0102] When voice is unclear or packet loss is high, the audio compression algorithm is adjusted to find a better balance between sound quality and bandwidth requirements. If packet loss is high, stronger error correction and retransmission mechanisms are implemented, and network configuration is optimized to reduce network congestion and ensure voice data packets are prioritized. When there is delay in the telephone voice signal, network paths and switching are minimized to reduce processing time in routers or switches. More efficient transmission protocols, such as VoIP optimization protocols, are used. This process adjusts the current telephone voice signal transmission scheme, resulting in an optimized telephone voice signal transmission scheme.
[0103] When control signals experience delays or loss, a higher-priority network channel is used for real-time control signals to ensure rapid transmission. Signal reliability is enhanced through error correction coding and fast retransmission strategies to reduce packet loss and errors. When control signal interference exists, a more interference-resistant frequency band, such as 5GHz instead of 2.4GHz, is used. More robust modulation techniques, such as OFDM, are employed to improve signal immunity to interference. This adjustment to the current control signal transmission scheme results in an optimized control signal transmission scheme.
[0104] Step S5: Control the wireless signal transmission of the elevator based on the adjusted wireless signal transmission scheme.
[0105] Specifically, in this technical solution, adjusting the wireless signal transmission scheme involves software configuration updates, network parameter adjustments, and physical equipment updates. For software configuration updates and network parameter adjustments, the server can directly perform real-time updates and adjustments. When new physical equipment needs to be installed, the server sends the adjustment method and the name of the equipment to be installed to the ground control terminal to notify management personnel to update the physical equipment in a timely manner, thereby optimizing the elevator's wireless signal transmission.
