DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] Embodiment 1: In Example 1, Figure 1 The implementation process of the building structure safety monitoring method provided by the embodiment of the present invention is shown and described in detail below: S100: Draw a wall structure diagram of a building and divide it into several independent areas, wherein the independent area consists of a target wall and several auxiliary walls, and the auxiliary walls are all connected to the target wall. Laser transmitters and receivers are respectively arranged on the target wall and the auxiliary walls, the laser transmitter is started, and the laser signal collected by the receiver is defined as a reference signal.

[0019] Draw a wall structure diagram of the building, and annotate the actual position, size, material and load-bearing function of each wall. Divide the wall structure diagram into multiple independent areas, each of which contains a target wall and several auxiliary walls, each of which is connected to the target wall, that is, the number of auxiliary walls is at least 1; deploy a laser transmitter on the target wall, and deploy a receiver on the auxiliary wall. The laser transmitter is responsible for emitting a laser beam, and the receiver is responsible for receiving the laser signal from the laser transmitter. By calculating the propagation time or signal strength of the laser signal from the transmitter to the receiver, the distance between the laser transmitter and the receiver can be obtained. While ensuring that the deployment positions of the laser transmitter and the receiver remain unchanged, the distance can be monitored to determine whether the target wall or the auxiliary wall is strained; in order to facilitate the subsequent processing of the laser signal, after starting the laser transmitter, the laser signal collected by the receiver is defined as the reference signal.

[0020] S200: Number the target wall, auxiliary wall, laser transmitter and receiver, create a sub-node consisting of a left node and a right node, migrate the reference signal to the sub-node, and synchronize the corresponding target wall and auxiliary wall numbers to the left node and the right node respectively, integrate all the sub-nodes, and construct a monitoring area corresponding to the independent area one by one.

[0021] According to the predetermined numbering rules, the target wall, auxiliary wall, laser transmitter and receiver are numbered, wherein the numbering rules are pre-established by the staff, the left node and the right node are mounted under the sub-node, the number of the target wall is transferred to the left node, and the number of the auxiliary wall is transferred to the right node; in addition, the number of the target wall can also be transferred to the right node, and the number of the auxiliary wall can be transferred to the left node. The transfer of the numbers is only to establish the corresponding relationship between the target wall and the auxiliary wall, and all the sub-nodes are hung down in the monitoring area.

[0022] For example, a wall A is randomly selected from the wall structure diagram, and its front view also includes three walls connected to the left, bottom and right of A. At this time, A is the target wall, and the other walls are auxiliary walls. Three groups of laser transmitters are arranged on A, and a receiver is installed on each auxiliary wall.

[0023] Create three child nodes A, B and C respectively. The left node of A's child node is the number of A, and the right node is the number of the left wall. The left node of B's ​​child node is the number of A, and the right node is the number of the lower wall. The left node of C's child node is the number of A, and the right node is the number of the right wall. All child nodes are migrated to the monitoring area.

[0024] S300: Based on a preset frequency, real-time signals are collected and uploaded to corresponding sub-nodes, and the number of sub-nodes in the monitoring area whose real-time signals are the same as the reference signals is counted. If the number is 0, the target wall in the monitoring area is defined as a strain wall, and the difference between the real-time signal and the reference signal is compared. The difference is input into a pre-built signal processing model, and the change value is output. The change value is filled into a preset template, a monitoring report is generated, and a label generated by the number of the target wall is inserted into the monitoring report.

[0025] According to the preset frequency, the receiver is used to collect the real-time signal of the laser transmitter, where the preset frequency can be once a day or once a week, and the real-time signal is uploaded to the corresponding sub-node.

[0026] The number of sub-nodes in the monitoring area whose real-time signals are the same as the reference signals is counted. If the number is 0, it means that the target wall has tilted or all the auxiliary walls have tilted. In either case, the difference between the real-time signals of each group of target walls and auxiliary walls is compared, and the difference is input into the signal processing model, where the signal processing model is a mathematical model that can analyze, process and interpret the laser signal during the wall strain monitoring process. It is mainly used to convert the change in the laser signal into a specific strain variable (i.e., the deformation variable of the wall). Furthermore, the signal processing model consists of a signal preprocessing layer, a calculation layer integrated with a phase ranging method, an error correction layer and an output layer.

[0027] The difference is input into the signal processing model, and the change is output. The change, the preset template and the target wall number are used to generate a monitoring report.

[0028] Continuing to elaborate on the example in S200, if the reference signal and the real-time signal in all subnodes in the monitoring area are different, it means that wall A is strained, and it is also possible that all the walls on the left, below and right of A are strained. At this time, by inputting the differences between all real-time signals and reference signals into the signal processing model, it is determined whether the output results are the same. If they are the same, it means that A is strained. Otherwise, it means that all the walls on the left, below and right of A are strained.

[0029] Embodiment 2: In Example 2, Figure 2 The implementation process of the building structure safety monitoring method provided by the embodiment of the present invention is shown. The step of "drawing a wall structure diagram of the building and dividing it into several independent areas" in the method is described in detail as follows: S101: Acquire the properties of the auxiliary wall, wherein the properties include at least: material, thickness and position.

[0030] S102: Based on the attributes, the priority of the auxiliary walls is configured, and independent areas are merged or re-divided.

[0031] According to the properties of the auxiliary wall, the priority of each auxiliary wall is determined, where the priority is used to characterize the difficulty of the auxiliary wall to be strained. The higher the priority, the easier it is for the auxiliary wall to be strained. When comparing the real-time signal and the reference signal, the auxiliary walls are compared in descending order of priority.

[0032] If the priority of the auxiliary wall is higher than that of the target wall, the auxiliary wall should continue to be segmented; for example, a wooden structure is connected to a concrete wall, and the wooden structure is more susceptible to strain. In this case, the wooden structure should also be used as the target wall for laser signal analysis.

[0033] Embodiment 3: In Example 3, Figure 2 The implementation process of the building structure safety monitoring method provided by an embodiment of the present invention is shown. The step of "defining the laser signal collected by the receiver as a reference signal" in the method is described in detail as follows: S103: Adding a time stamp to the reference signal and the real-time signal.

[0034] By adding a timestamp, it is convenient to record the laser signal changes of the target wall, thereby monitoring the wall strain in real time.

[0035] S104: Importing the reference signal and the real-time signal into a pre-built monitoring data set in chronological order.

[0036] The reference signal and the real-time signal are stored in chronological order to obtain a monitoring data set; the advantage of this is that historical data can be accumulated and danger signs can be identified in advance by observing the long-term trend of wall strain.

[0037] Embodiment 4: In Example 4, Figure 3 The implementation process of the building structure safety monitoring method provided by the embodiment of the present invention is shown. The step of "migrating the reference signal to the child node" in the method is described in detail as follows: S201: Traverse the influencing factors of the reference signal, wherein the influencing factors at least include: temperature and humidity, and integrate the influencing factors into the sub-node.

[0038] Determine the influencing factors of the reference signal; in actual monitoring, even if the target wall does not undergo strain, environmental changes may still cause deviations in the real-time signal. The real-time signal can be compensated by comparing the monitoring environment of the reference signal with the monitoring environment of the real-time signal to eliminate the deviation. The specific value of the compensation and the corresponding relationship between the monitoring environment should be determined in advance by the staff.

[0039] S202: Sort the sub-nodes in the monitoring area in descending order of priority.

[0040] In the monitoring area, the subnodes are sorted according to the priority of the auxiliary walls in the subnodes; the advantage of this is that the laser signal data of the walls that are more prone to strain can be processed preferentially.

[0041] Embodiment 5: In Example 5, Figure 4 The implementation process of the building structure safety monitoring method provided by the embodiment of the present invention is shown. The step of "counting the number of sub-nodes in the monitoring area whose real-time signals are the same as the reference signals" in the method is described in detail as follows: S301: Based on the sorting, all child nodes are compared in sequence; S302: If the real-time signal in the child node is the same as the reference signal, the corresponding child node is defined as a stable node, otherwise, it is defined as a changing node, and the number of all changing nodes and stable nodes in the monitoring area is counted.

[0042] According to the comparison results of the real-time signal and the reference signal of the sub-node, the sub-nodes are clustered into stable nodes and changing nodes. The stable node is used to characterize that the wall in the sub-node has not been strained, and the changing node is used to characterize that at least one wall in the sub-node has been strained.

[0043] Embodiment 6: In Example 6, different from Example 1, in this embodiment of the present invention, the method further includes: Constructing definition rules for the strain wall and integrating the definition rules into the monitoring area; The definition rules are: If the number of the stable nodes is 0, the target wall in the monitoring area is defined as a strain wall; If the number of the change nodes is 0, no definition is performed; If the number of the stable nodes and the number of the change nodes are not 0, the sub-nodes whose real-time signals are different from the reference signals are found in the monitoring area, and the auxiliary walls in the found sub-nodes are defined as strain walls.

[0044] In this embodiment, there is only one target wall and at least one auxiliary wall in a monitoring area. According to the number of stable nodes and change nodes in the monitoring area, the strain wall is determined and the number of the strain wall is found, wherein the strain wall is the wall that is tilted or cracked.

[0045] Embodiment 7: In Example 7, different from Example 1, in this embodiment of the present invention, the method further includes: Locating the deployment positions of the laser transmitter and receiver; Based on the change value, the strain trend of the wall is determined, and the deployment position is adjusted.

[0046] If strain is detected on the wall, record the strain trend of each wall. If the strain trend of a wall changes significantly, the deployment focus should be shifted to that wall to ensure that the tiny strain of the wall is captured in time.

The building structure safety monitoring system 1 comprises: The layout module 11 is used to draw a wall structure diagram of the building and divide it into several independent areas, wherein the independent area consists of a target wall and several auxiliary walls, and the auxiliary walls are all connected to the target wall.
