[0074] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0075] In order to timely and effectively monitor the potential safety hazards caused by the settlement or deformation of the building structure, the following solutions are proposed.

[0076] Please refer to Figure 1As shown in the figure, the present invention provides a method for monitoring the operation safety of a building structure. First, step S1 can be executed to deploy optical positioning sensors and / or radio positioning sensors according to the building structure. Then, step S2 can be executed to obtain the deformation amount of the building structure based on the positioning values and relative position values of the optical positioning sensors and / or radio positioning sensors. Then, step S3 can be executed to obtain the displacement amount of the building structure based on the deformation amount of the building structure and the positioning values and relative position values of the optical positioning sensors and / or radio positioning sensors. Finally, step S4 can be executed to obtain the operation safety level of the building structure based on the deformation amount of the building structure and the displacement amount of the building structure. By obtaining the deformation amount and displacement amount of the building structure through optical positioning sensors and radio positioning sensors, and then obtaining the operation safety level of the building structure, which is automatically obtained by the sensors during this process, the problems of untimely operation safety and low automation degree of the building structure are solved.

[0077] In addition, the method for monitoring the operation safety of the building structure of the present invention can also set an information acquisition terminal. At the same time, an inclination sensor, a crack meter, and a static level are respectively installed at the corners, walls, roofs, and house foundations of the building structure. The inclination sensor is used to collect the inclination angle value of the building structure. The crack meter is used to collect the opening and closing degree of cracks or expansion joints in the building structure. Preferably, the crack needle adopts the OP-L-C series, and the crack needle is internally provided with a temperature sensor for synchronously measuring the temperature at the installation position and can also automatically perform real-time temperature compensation. The static level is used to measure the relative settlement values of each measuring point on the building structure. The inclination sensor, the crack meter, the static level, and the temperature sensor are respectively connected to the information acquisition terminal in a signal connection manner. The information acquisition terminal can receive the relevant electrical signals detected by the inclination sensor, the crack meter, the static level, and the temperature sensor.

[0078] Set a signal conversion terminal to convert the electrical signals of the information acquisition terminal into digital signals through the signal conversion terminal. Digital signals are convenient for analysis and long-distance transmission of data.

[0079] Set a transmission and communication terminal, which is responsible for forming communication and data transmission between the digital signals converted by the signal conversion terminal and the cloud platform. The data transmission method is through wired transmission or wireless transmission. Wired transmission sends data to the cloud platform and the cloud platform sends data down through optical fibers and network cables via a gateway. Wireless transmission mainly transmits data to the cloud platform and the cloud platform sends data down through 2G / 3G / 4G / 5G.

[0080] The cloud platform analyzes the received digital signal information. When the safety data indicators of the building structure are unqualified, it will send a warning message to the mobile terminal of the management personnel in the form of text messages or emails to remind the management personnel to timely conduct a safety assessment of the current state of the building structure.

[0081] The principle and effect of the above technical solution are as follows:

[0082] It can achieve 24-hour real-time monitoring, fully automated online monitoring of tilt sensors, crack gauges, static level gauges, etc. of building structures, and grasp the safety status of the overall construction / operation of the house in real time, and overall grasp the health and safety status of the house. When data anomalies occur, that is, when the safety data indicators of the building structure are unqualified, the cloud platform will trigger the corresponding alarm mechanism and send it to the management personnel in the form of text messages and emails in the first time, and can also notify users in the form of faxes, broadcasts, etc., so that the person in charge can know that there are abnormal situations on the site in the first time.

[0083] Please refer to Figure 2 As shown, in the above step S1, step S11 can be first executed to obtain the load-bearing, shear, tensile, and torsional stress parts of the building structure. Next, step S12 can be executed to deploy optical positioning sensors / or radio positioning sensors on the load-bearing, shear, tensile, and torsional stress parts of the building structure. Next, step S13 can be executed to deploy optical positioning sensors / or radio positioning sensors on other parts of the building structure except the load-bearing, shear, tensile, and torsional stress parts. Next, step S14 can be executed to obtain the types and positions of optical positioning sensors / or radio positioning sensors that are more sensitive to the deformation amount and displacement amount of the building structure under the state of the deformation amount and displacement amount of the same building structure. Finally, step S15 can be executed to increase the deployment of optical positioning sensors / or radio positioning sensors that are more sensitive to the deformation amount and displacement amount of the building structure at the positions of the optical positioning sensors / or radio positioning sensors that are more sensitive to the deformation amount and displacement amount of the building structure.

[0084] Please refer to Figure 3 As shown, in the above step S13, step S131 can be first executed to obtain the number of optical positioning sensors / or radio positioning sensors to be deployed on other parts of the building structure except the load-bearing, shear, tensile, and torsional stress parts. Next, step S132 can be executed to obtain the distance between each point in other parts of the building structure except the load-bearing, shear, tensile, and torsional stress parts and the load-bearing, shear, tensile, and torsional stress parts of the building structure. Finally, step S133 can be executed to deploy optical positioning sensors / or radio positioning sensors on other parts of the building structure except the load-bearing, shear, tensile, and torsional stress parts according to the distance between each point in other parts of the building structure except the load-bearing, shear, tensile, and torsional stress parts and the load-bearing, shear, tensile, and torsional stress parts of the building structure.

[0085] In the step of arranging optical positioning sensors and / or radio positioning sensors at other parts of the building structure except for the load-bearing, shear, tensile, and torsional stress-bearing parts according to the distance between each point at other parts of the building structure and the load-bearing, shear, tensile, and torsional stress-bearing parts of the building structure as described above, the integral of the distance between each point at other parts of the building structure and each point at the load-bearing, shear, tensile, and torsional stress-bearing parts of the building structure can be obtained first. Then, the step of arranging optical positioning sensors and / or radio positioning sensors at other parts of the building structure except for the load-bearing, shear, tensile, and torsional stress-bearing parts can be executed, so that the number of optical positioning sensors and / or radio positioning sensors arranged at other parts of the building structure except for the load-bearing, shear, tensile, and torsional stress-bearing parts is positively correlated with the integral of the distance between each point at other parts of the building structure and each point at the load-bearing, shear, tensile, and torsional stress-bearing parts of the building structure.

[0086] Please refer to Figure 4 As shown, in step S2 as described above, step S21 of obtaining the position of the optical positioning sensor in the building structure can be executed first. Next, step S22 of obtaining the position of the radio positioning sensor in the building structure can be executed. Next, step S23 of obtaining the relative position positioning history record between the optical positioning sensors can be executed. Next, step S24 of obtaining the absolute position positioning history record of the radio positioning sensor can be executed. Finally, step S25 of obtaining the deformation amount of the building structure based on the relative position positioning history record between the optical positioning sensors and the absolute position positioning history record of the radio positioning sensor can be executed.

[0087] In the step of obtaining the deformation amount of the building structure based on the relative position positioning history record between the optical positioning sensors and the absolute position positioning history record of the radio positioning sensor as described above, the low-precision deformation amount of the building structure can be obtained first based on the relative position positioning history record between the optical positioning sensors. Then, the step of correcting the low-precision deformation amount of the building structure based on the absolute position positioning history record of the radio positioning sensor to obtain the deformation amount of the building structure can be executed.

[0088] In the step of correcting the low-precision deformation amount of the building structure based on the absolute position positioning history record of the radio positioning sensor to obtain the deformation amount of the building structure as described above, the step of correlating the relative position positioning history record between the optical positioning sensors and the absolute position positioning history record of the radio positioning sensor according to the acquisition time can be executed first. Next, the step of correcting the low-precision deformation amount of the building structure based on the absolute position positioning history record of the radio positioning sensor that is correlated with each other according to the acquisition time to obtain the deformation amount of the building structure can be executed.

[0089] Please refer to Figure 5 As shown, in step S3, step S31 can be first executed to obtain the low-precision displacement of the building structure according to the positioning value of the radio positioning sensor. Next, step S32 can be executed to obtain the distance between the radio positioning sensors according to the optical positioning sensor. Finally, step S3 can be executed to correct the low-precision displacement of the building structure according to the distance between the radio positioning sensors obtained by the optical positioning sensor, and obtain the displacement of the building structure.

[0090] Please refer to Figure 6 As shown, in step S4, step S1 can be first executed to obtain the set operating safety level classification of the building structure. Next, step S42 can be executed to correspond the deformation amount of the building structure and the displacement amount of the building structure to the set operating safety level classification of the building structure. Finally, step S43 can be executed to obtain the operating safety level of the building structure according to the deformation amount of the building structure, the displacement amount of the building structure, and the set operating safety level classification of the building structure.

[0091] Preferably, the deformation amount of the building structure also includes the deformation amount of the foundation of the building structure. Stress sensors are arranged at different positions of the foundation of the building structure to detect the stress distribution in the foundation, and the detected stress distribution information of the foundation is transmitted to the control center of the cloud platform. The control center calculates the deformation amount of the foundation of the building structure through the following formula

[0092]

[0093] where S is the final deformation amount of the foundation, in millimeters, S' is the deformation amount of the foundation calculated by the layered summation method is the settlement calculation empirical coefficient, which can generally be determined according to the foundation settlement observation data and experience. When there is no regional experience, it can be taken in the range of 0.2 - 1.4 according to the requirements of the design code. n is the number of soil layers divided within the foundation deformation calculation depth, p o corresponds to the additional pressure value at the foundation bottom surface under the quasi-permanent combination of load effects, in kilopascals, p o is calculated by multiplying the load standard value per square meter by the floor height and then multiplying by the quasi-permanent coefficient, and the quasi-permanent coefficient generally takes a value of 0.7.

[0094] E si is the compression modulus of the i-th layer of soil under the foundation bottom surface, and should be calculated for the pressure section of the sum of the self-weight pressure and the additional pressure of the soil, in megapascals, z i 、z i-1 are the distances from the foundation bottom surface to the bottom surfaces of the i-th layer of soil and the i - 1-th layer of soil, in meters, a i 、a i-1Calculate the average additional stress coefficient within the range from the base surface calculation point to the bottom surface of the i-th layer of soil and the (i-1)-th layer of soil;

[0095] When considering the quasi-permanent combination of load effects, the additional pressure p at the base of the foundation o is calculated through the following formula:

[0096]

[0097] where p is the standard value of the load per square meter estimated, n is the number of floors, is the quasi-permanent coefficient, with a value of 0.7, h is the buried depth of the basement foundation, generally about 3.2 meters, and it may also be other values, and π is the weighted average unit weight of the soil;

[0098] In the above formula, the average additional stress coefficient is obtained through the following method: The foundation length l and foundation width b of the building structure foundation are obtained through an optical positioning sensor and / or a radio positioning sensor, as well as the vertical distance z from the calculation point to the base of the foundation. Then, the ratio l / b of the foundation length l to the foundation width b and the ratio z / b of the vertical distance z to the foundation width b are calculated respectively. The corresponding average additional stress coefficient is queried through Appendix K of Code for Design of Building Foundation GB50007. The relevant information in Appendix K of Code for Design of Building Foundation GB50007 can be pre-entered into the cloud platform in advance, and the cloud platform calculates and corresponds according to the detected data values by itself, so as to obtain the average additional stress coefficient;

[0099] The cloud platform compares the foundation deformation amount of the building structure obtained with the preset safe foundation deformation amount. When the foundation deformation amount of the building structure exceeds the range of the preset safe foundation deformation amount, the cloud platform sends a warning message to the mobile terminal of the management personnel in the form of a text message or an email, reminding the management personnel to conduct a safety assessment of the current state of the building structure in a timely manner.

[0100] The principle and technical effect of the above technical solution are as follows: It can relatively accurately calculate the foundation deformation amount of the building structure by combining the detected data information through the cloud platform. The deformation amount of the foundation has a crucial impact on the safety of the entire building structure. By comparing the calculated foundation deformation amount with the preset safe foundation deformation amount, it is judged whether the current foundation situation of the building structure is still within the safe range. If there are potential safety hazards, the management personnel will be notified in a timely manner for further investigation and assessment. If there are particularly dangerous situations, the residents can also be notified in a timely manner through broadcasts and other forms, so as to minimize the danger brought by the safety hazards of the building structure and improve the safety guarantee.

[0101] Please refer to Figure 7As shown, the present invention also provides a building structure operation safety monitoring system, which may include a plurality of optical positioning sensors 1, a plurality of radio positioning sensors 2, a planning unit 3, and a calculation unit 4. Among them, the planning unit 3 can be used to arrange optical positioning sensors and / or radio positioning sensors according to the building structure. The calculation unit 4 can be used to obtain the deformation amount of the building structure based on the positioning values and relative position values of the optical positioning sensors and / or radio positioning sensors. It can also be used to obtain the displacement amount of the building structure based on the deformation amount of the building structure, as well as the positioning values and relative position values of the optical positioning sensors and / or radio positioning sensors. It can also be used to obtain the operation safety level of the building structure based on the deformation amount of the building structure and the displacement amount of the building structure.

[0102] In summary, through the collaborative work among the optical positioning sensors, radio positioning sensors, planning unit, and calculation unit, the present invention realizes the automatic and rapid deformation and settlement monitoring of the building structure.
