Description

Technical Field

[0001] The invention relates to the technical field of intelligent monitoring, and in particular to an intelligent monitoring and early warning system for a self-balancing cable-rod glass curtain wall. Background Art

[0002] Self-balancing cable-rod glass curtain wall is a prestressed self-balancing system composed of cables or rods and steel structures. It is widely used in the field of modern architecture, especially in commercial buildings, public buildings and office buildings. Self-balancing cable-rod glass curtain wall is mainly composed of cables or rods, steel structures and glass panels. The cables or rods are prestressed to form a self-balancing system, which effectively reduces the impact of external loads on the main structure. Among them, the rods and cables are prestressed by the pre-tensioning method. The prestress relies on its own structural balance, so that the load transferred to the main structure can be significantly reduced under the action of external loads.

[0003] The self-balancing cable-rod glass curtain wall achieves its stability and safety through the prestressed balance of the cable-rod and steel structure. However, under the influence of external factors such as wind pressure, temperature changes, earthquakes, etc., the curtain wall may move. If the displacement exceeds a certain limit, it may affect the overall structural safety and stability of the curtain wall. Therefore, through displacement monitoring and early warning, excessive displacement can be detected and prevented in time.

[0004] However, the monitoring methods for self-balancing cable-rod glass curtain walls on the market are relatively simple, generally using full coverage monitoring or random inspection monitoring. Both of the above methods cannot monitor the local displacement of the glass curtain wall in a timely manner. Once the local displacement exceeds the limit, the adverse effects caused by the falling of the glass are difficult to predict.

[0005] Therefore, there is an urgent need for a system that can monitor the displacement of local glass curtain walls and take into account the needs of real-time displacement monitoring and predictive analysis. Summary of the invention

[0006] The purpose of the present invention is to provide a self-balancing cable-rod glass curtain wall intelligent monitoring and early warning system to solve the above technical problems.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] A self-balancing cable-rod glass curtain wall intelligent monitoring and early warning system, comprising:

[0009] A laser emitting and reflecting device, which is arranged on the top of the glass curtain wall and includes a laser emitting end and a laser reflecting receiving port;

[0010] After the laser emitting end emits a laser beam downward, the laser beam is reflected upward by a reflecting device arranged at the bottom of the glass curtain wall and is received by a laser reflection receiving port;

[0011] The monitoring area division module is used to divide the glass curtain wall into multiple sub-monitoring areas at equal intervals, and each sub-monitoring area is equipped with a laser reflection and emission device;

[0012] A monitoring data acquisition module is used to collect laser signals from the laser reflection and emission device and convert them into electrical signals for recording;

[0013] A monitoring data processing module is used to digitally process the recorded electrical signals and extract information about the reflection path of the laser beam;

[0014] Analysis and judgment module, direct analysis unit and predictive analysis unit;

[0015] The direct analysis unit is used to judge whether the laser signal of the laser reflection and emission device is interrupted. If the laser signal is interrupted, it is judged that the displacement of the sub-monitoring area where the laser reflection and emission device is currently located exceeds the standard, and an alarm signal is generated. Otherwise, it is judged to be safe;

[0016] The prediction and analysis unit is used to analyze the displacement of the sub-monitoring area to be judged safe within a unit time, and predict whether there is a trend of displacement exceeding the standard in the current sub-monitoring area. If there is a trend of displacement exceeding the standard in the current sub-monitoring area, an early warning signal is generated, otherwise, no early warning signal is generated;

[0017] The early warning module is used to issue an alarm or early warning based on the results of the analysis and judgment module.

[0018] As a further technical solution, the system further includes a deflection adjustment module, which is installed on the top of the glass curtain wall and connected to the laser emitting end.

[0019] As a further technical solution, the process of analyzing the displacement of the sub-monitoring area in unit time for judging safety includes:

[0020] The initial emission laser beam path of the marking laser emission end is the standard path X0 and the laser beam emission angle α0;

[0021] The deflection adjustment module drives the laser emitting end to slowly deflect toward one side of the glass curtain wall until the emitted laser beam of the laser emitting end contacts the glass curtain wall and causes the signal to be interrupted, and the laser reflection receiving port cannot receive the laser beam. After marking the angle between the laser beam emission path and the standard path X0, the deflection adjustment module drives the laser emitting end to return to the initial position.

[0022] The time length is set for each interval, and the above process is repeated once, so as to obtain the angles α1, α2, ...α in turn. i , ..., α n ;

[0023] By formula:

[0024]

[0025] Calculate the fluctuation coefficient K of the current monitoring area q ;

[0026] Among them, n is the total number of times the angle is collected, i is the i-th time, is the reference coefficient, α max is the maximum value of the total number of times the included angle is collected, α min is the minimum value among the total number of times the included angle is collected;

[0027] The fluctuation coefficient K q and the preset fluctuation threshold K q0 contrast;

[0028] If K q -K q0 ≥0, it is judged that there is displacement fluctuation in the current monitoring area;

[0029] If K q -K q0 <0, it is judged that there is no displacement fluctuation in the current sub-monitoring area.

[0030] As a further technical solution, the process of analyzing the displacement of the sub-monitoring area in unit time for judging safety also includes:

[0031] Establish a coordinate system with time as the horizontal axis and angle as the vertical axis;

[0032] Set α1, α2, ...α i , ..., α n Draw the coordinate points in the coordinate system in sequence according to time:

[0033] Connect the adjacent coordinate points with smooth curves to get the actual change curve of the angle over time α j (t);

[0034] Change α1 to α n The interval between them is taken as a monitoring period and divided into y sub-periods;

[0035] By formula:

[0036]

[0037] Calculate the change coefficient K of the current monitoring area j ;

[0038] Wherein, j is the jth sub-period, ωj is the weight coefficient corresponding to the jth sub-period, t0 and t1 are the start time and end time of the sub-period respectively, and α1(t) represents the horizontal straight line passing through the coordinate point α1;

[0039] The coefficient of variation K j The preset change threshold K j0 contrast;

[0040] If K j -K j0 ≥0, it is judged that there is a high probability of displacement in the current sub-monitoring area;

[0041] If K j -K j0 <0, it is judged that the probability of displacement in the current sub-monitoring area is small.

[0042] As a further technical solution, the process of predicting whether there is a trend of displacement exceeding the standard in the current monitoring area is as follows:

[0043] By formula:

[0044]

[0045] Calculate the total displacement trend index K of the current monitoring area 总 ;

[0046] The displacement trend indicator K 总 and the preset displacement trend threshold K 阈 Compare;

[0047] If K 总 ≥K 阈 , it is judged that there is a trend of displacement exceeding the standard in the current sub-monitoring area;

[0048] Otherwise, it is judged that there is no trend of exceeding the displacement standard in the current sub-monitoring area.

[0049] As a further technical solution, the prediction and analysis unit also includes a process of determining whether the overall glass curtain wall has a tendency to exceed the displacement standard;

[0050] The sub-monitoring areas that are judged to have a displacement exceeding the standard trend are marked in red, the sub-monitoring areas where there are displacement exceeding the standard are marked in yellow, and the remaining sub-monitoring areas are marked in green;

[0051] Draw the marked color areas of the entire glass curtain wall on the standard specifications picture;

[0052] Get the center point A of each red area, the center point B of the yellow area, and the center point C of the green area;

[0053] Within the set circular range centered on each center point A, the influence coefficient of each center point A is calculated based on the number of center points B included and the straight-line distance between each center point B and the center point A. The influence coefficient of each center point A is used as the basis for judging the influence of the center point A.

[0054] If the influence of the center point A is large, the set circular range of the current center point A is doubled, otherwise, the set circular range of the current center point A is maintained;

[0055] By formula:

[0056]

[0057] Calculate the coverage range P;

[0058] Among them, S N is the area of ​​the circle around the Nth center point A, S 总 is the total area of ​​the glass curtain wall;

[0059] If P ≥ 1 / 3, it is judged that the overall glass curtain wall has a tendency of exceeding the displacement standard; otherwise, it is judged that the overall glass curtain wall does not have a tendency of exceeding the displacement standard.

[0060] As a further technical solution, the influence coefficient of each center point A is calculated as follows:

[0061]

[0062] Among them, Y A is the influence coefficient of the current center point A, M is the number of center points B included in the set circular range of the current center point A, L max L is the maximum straight-line distance between each center point B and the current center point A. min The minimum straight-line distance between each center point B and the current center point A.

[0063] As a further technical solution, the process of generating the priority alarm sequence in the early warning module is:

[0064] The red areas corresponding to each alarm signal are arranged in descending order according to the influence coefficient, which is used as the priority alarm order.

[0065] Beneficial effects of the present invention:

[0066] (1) In order to predict the trend of the sub-monitoring area that has not exceeded the limit displacement, the present invention sets a prediction analysis unit to analyze the displacement of the sub-monitoring area that is judged to be safe in unit time, and predict whether the current sub-monitoring area has a trend of exceeding the limit displacement. If the current sub-monitoring area has a trend of exceeding the limit displacement, an early warning signal is generated, otherwise, no early warning signal is generated; thereby achieving the dual effects of direct monitoring and prediction analysis of the glass curtain wall, so as to provide maintenance personnel with sufficient response time, and at the same time, it can also avoid the adverse effects caused by the displacement of the glass curtain wall as much as possible;

[0067] (2) The present invention first obtains the angle between the emission path of the initial laser beam and the emission path of the laser beam adjusted by the deflection adjustment module, and collects the angle data each time according to a predetermined frequency, so that the displacement of the glass curtain wall can be judged according to the change of the angle. Obviously, if the displacement is larger, the angle between the emission path of the laser beam adjusted by the deflection adjustment module each time and the initial path will be smaller; therefore, the displacement of the glass curtain wall in the current sub-monitoring area is directly reflected by the difference between the maximum and minimum values ​​in the historical angle data in the above technical solution, and then associated with the value calculated by the standard deviation formula to obtain a more accurate fluctuation coefficient of the current sub-monitoring area. Obviously, the larger the fluctuation coefficient, the greater the fluctuation of the displacement amplitude in the sub-monitoring area, and the easier it is to develop into a displacement exceeding the limit. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] The present invention will be further described below in conjunction with the accompanying drawings.

[0070] Figure 2 It is a system structure block diagram of the present invention. DETAILED DESCRIPTION

[0071] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0072] See also Figure 1-Figure 2 As shown, a self-balancing cable-rod glass curtain wall intelligent monitoring and early warning system comprises:

[0073] A laser emitting and reflecting device, which is arranged on the top of the glass curtain wall and includes a laser emitting end and a laser reflecting receiving port;

[0074] After the laser emitting end emits a laser beam downward, the laser beam is reflected upward by a reflecting device arranged at the bottom of the glass curtain wall and is received by a laser reflection receiving port;

[0075] The monitoring area division module is used to divide the glass curtain wall into multiple sub-monitoring areas at equal intervals, and each sub-monitoring area is equipped with a laser reflection and emission device;

[0076] A monitoring data acquisition module is used to collect laser signals from the laser reflection and emission device and convert them into electrical signals for recording;

[0077] A monitoring data processing module is used to digitally process the recorded electrical signals and extract information about the reflection path of the laser beam;

[0078] Analysis and judgment module, direct analysis unit and predictive analysis unit;

[0079] The direct analysis unit is used to judge whether the laser signal of the laser reflection and emission device is interrupted. If the laser signal is interrupted, it is judged that the displacement of the sub-monitoring area where the laser reflection and emission device is currently located exceeds the standard, and an alarm signal is generated. Otherwise, it is judged to be safe;

[0080] The prediction and analysis unit is used to analyze the displacement of the sub-monitoring area to be judged safe within a unit time, and predict whether there is a trend of displacement exceeding the standard in the current sub-monitoring area. If there is a trend of displacement exceeding the standard in the current sub-monitoring area, an early warning signal is generated, otherwise, no early warning signal is generated;

[0081] The early warning module is used to issue an alarm or early warning based on the results of the analysis and judgment module.

[0082] The laser emission and reflection device used in this embodiment is a prior art. The specific structural principle and actual installation are routine choices of technicians in this field and are determined in combination with actual needs. No further description is given here. The substantial difference between this embodiment and the prior art is that a laser emission and reflection device is used instead of a single laser emission device as the basis for monitoring the displacement of the glass curtain wall. The laser beam has the characteristics of high concentration and good directionality, and can maintain a high energy density over a long distance. The laser emission and reflection device guides the laser beam to the monitoring point through a reflector, which reduces the interference of the laser beam by the external environment such as dust and fog during the transmission process. At the same time, the laser emission and reflection device is usually connected to the monitoring data acquisition module, which can transmit and analyze the monitoring data in real time. For the alarm sub-monitoring area, it can be simply judged by whether the laser signal is interrupted, which reduces the recognition load brought by the maintenance personnel and improves the monitoring alarm efficiency.

[0083] Moreover, in order to make trend predictions for sub-monitoring areas that have not exceeded the displacement limit, a prediction and analysis unit is set up to analyze the displacement of the sub-monitoring areas that are judged to be safe within a unit time, and predict whether there is a trend of exceeding the displacement limit in the current sub-monitoring area. If there is a trend of exceeding the displacement limit in the current sub-monitoring area, an early warning signal is generated; otherwise, no early warning signal is generated; thereby achieving the dual effects of direct monitoring and predictive analysis of the glass curtain wall, so as to provide maintenance personnel with sufficient response time, and at the same time avoid the adverse effects caused by the displacement of the glass curtain wall as much as possible.

[0084] The system further includes a deflection adjustment module, which is mounted on the top of the glass curtain wall and connected to the laser emitting end. The deflection adjustment module is a rotary motor that can change the angle of the laser emitting end, and the laser reflection receiving port can receive the laser beam emitted within a certain deflection angle. This is a prior art and will not be described in detail here.

[0085] The process of analyzing the displacement per unit time of the sub-monitoring area for judging safety includes:

[0086] The initial emission laser beam path of the marking laser emission end is the standard path X0 and the laser beam emission angle α0;

[0087] The deflection adjustment module drives the laser emitting end to slowly deflect toward one side of the glass curtain wall until the emitted laser beam of the laser emitting end contacts the glass curtain wall and causes the signal to be interrupted, and the laser reflection receiving port cannot receive the laser beam. After marking the angle between the laser beam emission path and the standard path X0, the deflection adjustment module drives the laser emitting end to return to the initial position.

[0088] The time length is set for each interval, and the above process is repeated once, so as to obtain the angles α1, α2, ...α in turn. i , ..., α n ;

[0089] By formula:

[0090]

[0091] Calculate the fluctuation coefficient K of the current monitoring area q ;

[0092] Among them, n is the total number of times the angle is collected, i is the i-th time, is the reference coefficient, α max is the maximum value of the total number of times the included angle is collected, α min is the minimum value among the total number of times the included angle is collected;

[0093] The fluctuation coefficient K q and the preset fluctuation threshold K q0contrast;

[0094] If K q -K q0 ≥0, it is judged that there is displacement fluctuation in the current monitoring area;

[0095] If K q -K q0 <0, it is judged that there is no displacement fluctuation in the current sub-monitoring area.

[0096] In this embodiment, a method for analyzing the displacement of a sub-monitoring area for judging safety within a unit time is provided. Specifically, the angle between the emission path of the initial laser beam and the emission path of the laser beam adjusted by the deflection adjustment module is obtained, and the angle data of each time is collected at a predetermined frequency, so that the displacement of the glass curtain wall can be judged according to the change of the angle. Obviously, if the displacement is larger, the angle between the emission path of the laser beam adjusted by the deflection adjustment module each time and the initial path will be smaller; therefore, the displacement of the glass curtain wall in the current sub-monitoring area is directly reflected by the difference between the maximum value and the minimum value in the historical angle data in the above technical solution, and then compared with the standard deviation formula The calculated values ​​are associated to obtain a more accurate fluctuation coefficient Kq of the current sub-monitoring area. Obviously, the larger the fluctuation coefficient, the greater the displacement amplitude fluctuation in the sub-monitoring area, and the easier it is to develop into a displacement exceeding the limit.

[0097] The process of analyzing the displacement of the sub-monitoring area per unit time for judging safety also includes:

[0098] Establish a coordinate system with time as the horizontal axis and angle as the vertical axis;

[0099] Set α1, α2, ...α i , ..., α n Draw the coordinate points in the coordinate system in sequence according to time;

[0100] Connect the adjacent coordinate points with smooth curves to get the actual change curve of the angle over time α j (t);

[0101] Change α1 to α n The interval between them is taken as a monitoring period and divided into y sub-periods;

[0102] By formula:

[0103]

[0104] Calculate the change coefficient K of the current monitoring area j ;

[0105] Among them, j is the jth sub-period, ωj is the weight coefficient corresponding to the jth sub-period, t0 and t1 are the start time and end time of the sub-period respectively, and α1(t) represents the horizontal straight line passing through the coordinate point α1;

[0106] The coefficient of variation K j The preset change threshold K j0 contrast;

[0107] If K j -K j0 ≥0, it is judged that there is a high probability of displacement in the current sub-monitoring area;

[0108] If K j -K j0 <0, it is judged that the probability of displacement in the current sub-monitoring area is small.

[0109] In this embodiment, in order to improve the accuracy of predicting displacement trends, the cumulative change of the historical angle is given. Obviously, the larger the cumulative change, the greater the deviation of the displacement amplitude in the sub-monitoring area, and the easier it is to develop into a displacement exceeding the limit. Specifically, by dividing it into multiple sub-periods, the deviation of the angle change curve in each sub-period can be more accurately compared with the reference straight line, and then the deviation within a monitoring period is obtained by accumulation, and then the change coefficient of the current sub-monitoring area is obtained.

[0110] The process of predicting whether there is a trend of displacement exceeding the standard in the current monitoring area is as follows:

[0111] By formula:

[0112]

[0113] Calculate the total displacement trend index K of the current monitoring area 总 ;

[0114] The displacement trend indicator K 总 and the preset displacement trend threshold K 阈 Compare;

[0115] If K 总 ≥K 阈 , it is judged that there is a trend of displacement exceeding the standard in the current sub-monitoring area;

[0116] Otherwise, it is judged that there is no trend of exceeding the displacement standard in the current sub-monitoring area.

[0117] In this embodiment, a specific method for predicting whether there is a trend of displacement exceeding the standard in the current monitoring area is given, by formula The fluctuation coefficient and the variation coefficient are associated to establish a prediction model, so as to achieve the purpose of accurately predicting the displacement trend and improve the accuracy of the prediction.

[0118] The prediction and analysis unit also includes a process for determining whether the overall glass curtain wall has a tendency to exceed the displacement standard;

[0119] The sub-monitoring areas that are judged to have a displacement exceeding the standard trend are marked in red, the sub-monitoring areas where the displacement exceeds the standard are marked in yellow, and the remaining sub-monitoring areas are marked in green;

[0120] Draw the marked color areas of the entire glass curtain wall on the standard specifications picture;

[0121] Get the center point A of each red area, the center point B of the yellow area, and the center point C of the green area;

[0122] Within the set circular range centered on each center point A, the influence coefficient of each center point A is calculated based on the number of center points B included and the straight-line distance between each center point B and the center point A. The influence coefficient of each center point A is used as the basis for judging the influence of the center point A.

[0123] If the influence of the center point A is large, the set circular range of the current center point A is doubled, otherwise, the set circular range of the current center point A is maintained;

[0124] By formula:

[0125]

[0126] Calculate the coverage range P;

[0127] Among them, S N is the area of ​​the circle around the Nth center point A, S 总 is the total area of ​​the glass curtain wall;

[0128] If P ≥ 1 / 3, it is judged that the overall glass curtain wall has a tendency of exceeding the displacement standard; otherwise, it is judged that the overall glass curtain wall does not have a tendency of exceeding the displacement standard.

[0129] The influence coefficient of each center point A is calculated as follows:

[0130]

[0131] Among them, Y A is the influence coefficient of the current center point A, M is the number of center points B included in the set circular range of the current center point A, L max L is the maximum straight-line distance between each center point B and the current center point A. min The minimum straight-line distance between each center point B and the current center point A.

[0132] In this embodiment, a method for judging whether the overall glass curtain wall has a displacement exceeding standard trend is provided. Specifically, the sub-monitoring area judged to have a displacement exceeding standard trend is first marked as red, wherein the sub-monitoring area with displacement exceeding standard is marked as yellow, and the remaining sub-monitoring areas are marked as green areas. Then, the entire glass curtain wall is drawn on a picture of standard specifications according to the marked color areas, and the center point A of each red area, the center point B of the yellow area, and the center point C of the green area are obtained. Then, the influence coefficient is calculated according to a predetermined calculation rule. The influence coefficient can directly reflect the joint effect of the current red area on the surrounding area. If there are more green areas near the current red area, the farther the yellow area is from the red area, which means that the red area has a small influence on the nearby area, that is, the displacement exceeding limit area has a small influence on the surrounding area and does not form diffusion. Therefore, the influence coefficient can directly reflect whether the displacement exceeding limit area forms diffusion to the surrounding area and the size of the diffusion speed. The larger the influence coefficient, the larger the affected range, so the preset circular range is doubled, and then the current trend of the overall glass curtain wall is reflected by the area ratio.

[0133] The process of generating the priority alarm sequence in the early warning module is as follows:

[0134] The red areas corresponding to each alarm signal are arranged in descending order according to the influence coefficient, which is used as the priority alarm order.

[0135] It should be noted that the calculation formulas and various parameters involved in the calculation in the present invention have been dimensionally processed in advance, and the process of dimensionless processing is well known in the industry and will not be described here.

[0136] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
