Description

Technical Field

[0001] This application relates to the technical field of bridge inspection, and in particular to a cable tension monitoring method, system, terminal, and storage medium. Background Technology

[0002] A cable-stayed bridge is a type of bridge where the main girder is directly connected to the bridge towers by numerous cables. A cable-stayed bridge mainly consists of towers, a main girder, and stay cables. Because the cable tension in a cable-stayed bridge reflects the overall internal force state of the bridge, the cable tension must be measured regularly throughout the construction process for cable adjustment and alignment control.

[0003] In related technologies, the main methods for monitoring and testing the cable force of cable-stayed bridges include pressure gauge measurement, pressure sensor measurement, and vibration measurement. Currently, vibration measurement is commonly used. Vibration measurement involves using a high-sensitivity sensor attached to the cable to pick up the vibration signal of the cable under environmental vibration excitation. After filtering, amplification, and spectral analysis, the natural frequency of the cable is determined based on the spectrum, and then the cable force is determined based on the relationship between the natural frequency and the cable force.

[0004] However, the cable force measurement results are greatly affected by environmental factors such as cable sag, damper, boundary conditions, and temperature. Therefore, the cable force calculated by the general formula for cable force calculation will deviate from the actual cable force, thus affecting the cable adjustment strategy. Summary of the Invention

Whether to send a cable adjustment request is determined based on the reference cable force value and the real-time cable force value.

[0007] By adopting the above technical solution, after obtaining the current real-time cable force value and the real-time environment, the historical environment that is closest to the real-time environment is determined from historical data. Then, based on the historical cable force value corresponding to the historical environment and the design temperature, a reference cable force value can be determined. The reference cable force value is the cable force value in the calculated real-time environment. When the reference cable force value deviates from the real-time cable force value, it indicates that the cable force has changed due to environmental factors, and maintenance personnel need to be notified to adjust the cable. This method can determine changes in cable force values ​​without considering the accuracy of the measured cable force values, thereby determining whether cable adjustment is necessary.

Identify the historical temperature range that is most similar to the real-time temperature range and the historical illumination range that is most similar to the real-time illumination range within the same time period.

[0012] In a preferred embodiment, this application can be further configured such that: the step of determining whether to send a cable adjustment request based on the reference cable force value and the real-time cable force value includes: Calculate the deviation between the reference cable force value and the real-time cable force value; Whether to send a search request is determined based on the deviation value and the preset deviation threshold.

[0013] In a preferred embodiment, this application can be further configured such that determining whether to send a search request based on the deviation value and a preset deviation threshold includes: If the deviation value is less than the deviation threshold, no search request will be sent; If the deviation value reaches the deviation threshold, a search request is sent.

[0014] The second objective of this application is to provide a cable force monitoring system that can accurately determine changes in cable force values.

[0019] The fourth objective of this application is achieved through the following technical solution: A computer-readable storage medium storing a computer program that can be loaded by a processor and executed by any of the above-described cable force monitoring methods.

Detailed Implementation

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article, unless otherwise specified, generally indicates that the preceding and following related objects have an "or" relationship.

[0029] This application provides a cable tension monitoring method applied to the field of bridge inspection, primarily targeting cable-stayed bridges, to detect the cable tension on the cables. Measuring the cable tension is of great significance to the entire construction and maintenance process of cable-stayed bridges. For example, before installing the cables, the cable tension of each cable needs to be designed. It should be noted that since cable tension changes with cable temperature, the designed cable tension is the tension at a specific temperature. During cable installation, it is necessary to ensure that the cable tension reaches the designed tension. Because the cable tension of each cable is also affected by the tension of adjacent cables, after all cables are installed, the cable tension of each cable needs to be measured again, and then adjusted to ensure that the cable tension of each cable reaches the corresponding design value. Furthermore, because cables are exposed to the elements for a long time, they are also subject to wear and tear due to environmental factors, which leads to changes in cable tension. Therefore, it is necessary to measure the cable tension regularly to determine whether the tension has changed and whether cable adjustment is required.

[0030] Furthermore, to collect cable tension values ​​in real time, a through-type anchor gauge or cable tension gauge is typically installed on each cable. However, the time required to collect cable tension values ​​is as long as 1 to 2 days, and the daily temperature variation is relatively large, resulting in different cable tension values ​​measured at different times. Therefore, a terminal device or server with data processing capabilities is needed to process the cable tension values ​​to eliminate errors caused by temperature variations, thereby facilitating accurate determination of whether the cable tension has changed. The aforementioned terminal device or server is used to execute the cable tension monitoring method disclosed in this application.

[0031] The embodiments of this application will now be described in further detail with reference to the accompanying drawings.

[0032] The main process of the cable-driven method provided in this application is described below.

[0033] like Figure 1 As shown: Step S100: Obtain historical data.

[0034] Historical data includes the historical cable force value and historical environment at every moment within each measurement period. The measurement period is the time interval for collecting cable force values. The measurement time can be adjusted as needed, and measurements are taken annually, potentially multiple times a year. During each measurement, not only the cable force value at each moment is recorded, but also the measurement environment. Therefore, historical data includes the historical cable force value and historical environment at every moment of each previous measurement. The historical cable force value is the cable force value measured previously. The historical environment includes factors affecting temperature changes, such as temperature and light intensity. Since these are the environments at previous measurement times, they are referred to as historical temperature values ​​and historical light intensity, respectively.

[0035] Step S200: Obtain the original cable force value at the design temperature.

[0036] The design temperature is the temperature selected when considering the magnitude of cable force. During actual construction, both the design temperature and the original cable force value must be considered. That is, the cable force of the installed cables must reach the original cable force value at the design temperature.

[0037] Step S300: Obtain the real-time cable force value and real-time environment for the current measurement period.

[0038] The current measurement period is the measurement period for this measurement. The cable force value measured at each moment in this measurement is called the real-time cable force value, and the environment in which this measurement takes place is called the real-time environment. Similarly, the real-time environment also includes real-time temperature and real-time light intensity. Both real-time temperature and real-time light intensity are values ​​that change over time.

[0039] Step S400: Based on the matching degree between the real-time environment and the historical environment, determine the reference cable force value according to the historical data and the original cable force value.

[0040] Understandably, since multiple measurements have been taken in the past, there will always be one or more historical environments that are similar to the real-time environment in the historical data. A major factor affecting environmental changes is time, specifically the month to which the measurement period belongs. Environmental changes within the same measurement period are only likely to be similar when the months of two measurements are the same. Therefore, before determining the matching degree between the real-time and historical environments, historical data needs to be filtered based on the month of the measurement period. Furthermore, only when the historical environment with the highest matching degree to the real-time environment is determined will the historical cable force value measured under that historical environment have reference value for the real-time cable force value. Therefore, a reference cable force value can be determined based on the historical cable force values ​​and original cable force values ​​collected when the historical environment is similar to the real-time environment in the historical data. The reference cable force value is the cable force value of the cable with the original cable force value at the design temperature in the current real-time environment. In this application, the reference cable force value is obtained through calculation, not an actual collected value.

[0041] In order to determine the reference cable force value more accurately based on historical data and the original cable force value, further processing of the historical data is required when the historical data is acquired.

[0042] Optionally, the processing steps for historical data include the following: First, the historical data is classified according to the historical environment and measurement period, resulting in multiple data groups.

[0043] The purpose of classifying historical data is to group historical cable stress values ​​within measurement periods with similar historical environments into the same data group. Therefore, when classifying, it is first necessary to group historical cable stress values ​​within the same month of the measurement period into the same group, and then further divide them according to historical environment. Specifically, classification conditions can be preset. For example, a data group can be defined as follows: historical temperature values ​​within the first temperature range and historical light intensity within the first light intensity range for the 8:00-12:00 time period; another data group can be defined as follows: historical temperature values ​​within the first temperature range and historical light intensity within the second light intensity range for the 8:00-12:00 time period; another data group can be defined as follows: historical temperature values ​​within the second temperature range and historical light intensity within the third light intensity range for the 12:00-14:00 time period; and another data group can be defined as follows: historical temperature values ​​within the third temperature range and historical light intensity within the fourth light intensity range for the 14:00-20:00 time period. Specifically, multiple data groups can be obtained by combining the extreme values ​​of all historical temperature values, the extreme values ​​of historical light intensity, and the preset time periods, according to the above classification conditions.

[0044] Then, the data from multiple data sets were fitted separately to obtain the fitted curves.

[0045] This section uses the fitting process of a dataset as an example to explain in detail.

[0046] First, the measurement period is divided into multiple unit periods based on the historical temperature and historical light intensity at each moment. Then, the average historical cable force value within each unit period is calculated and recorded as the first cable force value. Next, the mode of the first cable force values ​​within the same unit period across all measurement periods is calculated and recorded as the second cable force value. Finally, a fitted curve is determined based on all second cable force values.

[0047] The method of dividing the measurement period into multiple unit periods is similar to the aforementioned preset time period, but the duration of each unit period is shorter than the preset time period to ensure that the changes in historical temperature and historical light intensity are relatively small within each unit period. Since the cable force value increases with rising temperature and decreases with falling temperature, the influence of temperature on the cable force can be eliminated by calculating the average historical cable force value within each unit period. When all the first cable force values ​​are obtained, the first cable force value with the highest probability of occurrence can be selected according to a normal distribution and recorded as the second cable force value to eliminate the influence of external factors. Thus, a fitting curve for a specific historical environment can be obtained based on all the second cable force values.

[0048] It is worth noting that since the fitting curve of the reference environment can reflect the change of cable force value over time, and the trend of cable force value change over time is constant, if there is a deviation between the corresponding cable force value and the original cable force value at the moment when the temperature is equal to the temperature involved in the fitting curve of the reference environment, the magnitude of the cable force value in the fitting curve can be adjusted according to the deviation value for correction.

[0049] Optionally, step S400 includes the following steps: Step S410: Determine the historical environment with the highest similarity to the real-time environment and denote it as the reference environment.

[0050] To calculate similarity more accurately, it can be done by time period.

[0051] Taking a single measurement as an example, the similarity between its historical and real-time environments is calculated as follows: First, the real-time temperature range and real-time illumination range for each unit time period are determined based on the real-time temperature and real-time illumination intensity. The real-time temperature range is defined by the minimum and maximum real-time temperature values ​​within that unit time period. The real-time illumination range is defined by the minimum and maximum real-time illumination intensity within that unit time period.

[0052] Then, based on the historical temperature and historical light intensity of each measurement period, the historical temperature range and historical light intensity range within each unit period are determined. The calculation method for the historical temperature range and historical light intensity range is the same as that for the real-time temperature range and real-time light intensity range.

[0053] Furthermore, the historical temperature range most similar to the real-time temperature range and the historical illumination range most similar to the real-time illumination range within the same time unit are identified. Specifically, the similarity for each time unit can be determined one by one, and the similarity is the average of the temperature similarity and illumination similarity. The temperature similarity is the ratio of the smaller of the maximum value of the historical temperature range and the maximum value of the real-time temperature range to the larger of the two maximum values. The illumination similarity is the ratio of the smaller of the maximum value of the historical intensity range and the maximum value of the real-time intensity range to the larger of the two maximum values. After calculating the similarity for all time units, the average value is calculated to obtain the final similarity.

[0054] Step S420: Determine the reference cable force value based on the fitting curve corresponding to the reference environment and the real-time cable force value.

[0055] After determining the reference environment, the data group to which the reference environment belongs can be identified, and then the corresponding fitted curve can be retrieved. Once a real-time cable force value is selected, the corresponding time point can be chosen from the corrected fitted curve to obtain the reference cable force value.

[0056] Step S500: Determine whether to send a cable adjustment request based on the reference cable force value and the real-time cable force value.

[0057] Specifically, the deviation between the reference cable force value and the real-time cable force value can be calculated, and then a cable adjustment request can be sent based on the deviation value and a preset deviation threshold. It's important to understand that a deviation between the reference and real-time cable force values ​​does not necessarily require adjustment; adjustment is only necessary when the deviation is excessively large. Therefore, a deviation threshold is set to determine whether adjustment is needed. If the deviation is less than the deviation threshold, no adjustment request is sent. If the deviation reaches the deviation threshold, an adjustment request is sent.

[0058] Of course, the deviation between the reference cable force value and the real-time cable force value can also be calculated by calculating the ratio of the reference cable force value to the real-time cable force value. The deviation threshold can be adjusted adaptively according to the actual situation.
