[0003] Current corrosion monitoring methods usually require inspectors to conduct periodic inspections, usually on-site visual inspections or using pitting and curve methods. Visual inspections require professional technicians to evaluate and cannot obtain accurate data and quantitative indicators. Secondly, pitting and curve methods are often based on a single data point on a single root and cannot accurately reflect the corrosion of the entire bolt ball grid.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] The present invention discloses a corrosion monitoring system for bolt ball grid rods, please refer to Figures 1 to 4In some embodiments, the corrosion monitoring system includes a corrosion sensor 1, an environmental monitoring device 2, a server 3 and a management terminal 4. The corrosion sensor 1 is installed in the bolt ball grid rod to sense the real-time environmental parameters inside the bolt ball grid rod. The corrosion situation inside the bolt ball grid rod can be calculated by reading the real-time environmental parameters of the corrosion sensor 1 and the basic material of the bolt ball grid rod through the corrosion sensor 1 installed in the bolt ball grid rod. The environmental monitoring device 2 is installed outside the bolt ball grid rod to sense the real-time environmental parameters outside the bolt ball grid rod. It can monitor the main weather factors including but not limited to temperature, humidity, wind pressure or precipitation in the area where the bolt ball grid rod is located. The server 3 is wirelessly connected to the corrosion sensor 1 and the environmental monitoring device 2, collects the data of the corrosion sensor 1 and the environmental monitoring device 2 and runs the internal corrosion monitoring and evaluation method to obtain the actual corrosion situation of the bolt ball grid rod, and combines the above weather factors with the corrosion situation obtained in the corrosion sensor 1, and compares it with the preset algorithm formed by the internal big data algorithm and deep learning to form a corrosion analysis report, so that the operator and the inspector can obtain the corrosion situation and analyze the cause of the corrosion in time. The management terminal 4 is wirelessly connected to the corrosion sensor 1 and the server 3. Specifically, the management terminal 4 can be an application in the mobile phone of the inspector or the manager. On the one hand, it can receive the data of the corrosion sensor 1 and the environmental monitoring device 2 through the server 3 to obtain more comprehensive data; on the other hand, it can also directly monitor the measurement data on the corrosion sensor 1, and can query and retrieve it in the application to ensure that the inspector can independently obtain the corrosion situation inside the bolt ball grid rod when it is necessary to exclude the influence of external environmental factors for analysis. In addition, the server 3 is also provided with an alarm system, which can send information to the management terminal 4 via email or text message when the corrosion is serious, so that the inspectors and operators can obtain the alarm information in time and carry out subsequent repairs or replacements.

[0024] Furthermore, the corrosion monitoring system also includes a server monitoring terminal 5, which is usually set at the unified management personnel of the bolt ball grid rods, and is used to analyze the corrosion status and manage the health status of the entire bolt ball grid rods. Since the bolt ball grid rods are usually not independently set, but are continuously connected by bolts to form a grid structure, they are not only affected by their own status and internal and external environmental factors, but also by the status of adjacent bolt ball grid rods. The server monitoring terminal 5 is wirelessly connected to multiple servers 3 and management terminals 4, receives and summarizes the data in multiple servers 3 and management terminals 4, analyzes the corrosion status and health status between each bolt ball grid rod, and avoids the spread of corrosion through the contact between the bolt ball grid rods, so that the corrosion status of the bolt ball grid rods is more serious than the corrosion status calculated by the corrosion sensor 1 and the environmental monitoring device 2, further ensuring the accuracy of the corrosion status analysis between the bolt ball grid rods, and at the same time making it easier for prosecutors to obtain historical corrosion status, ensuring the accuracy of the corrosion status analysis of the bolt ball grid rods, and improving the management personnel's control over the status of the entire bolt ball grid.

[0025] The present invention discloses a method for monitoring and evaluating corrosion of a bolt-ball grid rod, which runs in a server 3. In some embodiments, the method for monitoring and evaluating corrosion of a bolt-ball grid rod specifically includes:

[0026] Step S1: The real-time corrosion status value of the bolt ball grid rod is obtained through the preset corrosion sensor 1, and compared with the preset corrosion status value in the server 3 to obtain the corrosion degree grade.

[0027] Among them, the environmental data inside the bolt ball grid rod is collected by the corrosion sensor 1 preset inside the bolt ball grid rod, including but not limited to humidity, oxygen concentration, pressure and current data. And the real-time corrosion status value is calculated based on the environmental data obtained. In addition, the preset corrosion degree status value in the server 3 usually needs to be determined by comprehensively considering multiple factors, including but not limited to the external environmental conditions of the area where the bolt ball grid dry frame is located and the properties of the rod material itself. Through the combination of corrosion testing in the production process and historical corrosion maintenance experience of the same material, professionals set a series of preset corrosion degree status values ​​that meet the relevant national standards for construction and engineering. Therefore, by comparing the real-time corrosion state value with the preset corrosion degree state value, a corrosion risk level with a certain unified standard and accuracy can be obtained, which further ensures the accuracy of the entire corrosion monitoring and evaluation method for detecting the corrosion degree of the bolt ball grid rod.

[0028] Step S2: Obtain the real-time environmental parameters and the basic data of the bolt-ball grid members to calculate the environmental parameter impact value.

[0029] Since the bolt ball grid structure is often set outside the building, the influence of the external environment on the corrosion accounts for a large proportion. Therefore, in some application scenarios, the climate environment monitoring equipment (not shown) in the area accessed by the server 3 is used to obtain the real-time environmental parameters of the area where the bolt ball grid rod is located. At the same time, the basic data such as the material properties of the bolt ball grid rod are obtained, and it is combined with the real-time environmental parameters obtained by the climate environment monitoring equipment to obtain the environmental parameter impact value of the bolt ball grid rod of this material, so as to quantify the environmental factors and facilitate the subsequent continuous analysis.

[0030] Step S3: The corrosion risk level of the bolt-ball grid member is calculated by using the real-time corrosion state value and the environmental parameter influence value.

[0031] In some application scenarios, the corrosion risk level of the bolt-ball grid rods, that is, the service life of the bolt-ball grid rods, can be obtained based on the current real-time corrosion status value of the bolt-ball grid rods and combined with the current environmental parameter influence values ​​in the area. The corrosion monitoring and evaluation method is further used to realize the corrosion level analysis and subsequent service life analysis of the corresponding bolt-ball grid rods.

[0032] Step S4: Analyze the environmental parameter impact values ​​and corrosion risk level values ​​and generate an analysis report.

[0033] In some application scenarios, the external environment and the real-time corrosion degree are introduced, and the corresponding quantitative data are obtained to analyze the corrosion degree and service life of the entire bolt ball grid rod, so as to obtain a clearer and more accurate corrosion condition of the entire bolt ball grid. In addition, since the obtained real-time corrosion state value and environmental parameter impact value can be obtained in real time through the corrosion sensor 1 and the climate environment monitoring equipment, and analyzed in the server 3, the operator can also obtain it remotely through the management terminal, so that the corrosion monitoring of the bolt ball grid rod can be carried out according to actual needs or at a specific time, which greatly simplifies the corrosion monitoring cost for the bolt ball grid rod.

[0034] Furthermore, the real-time environmental parameters and the corrosion risk level are obtained to calculate the environmental parameter impact value, which specifically includes:

[0035] Step S21: Calculate the environmental parameter impact value through the formula: Q=kSE.

[0036] Among them, Q is the environmental parameter impact value, S is the corrosion risk level value of the bolt ball grid rod, and the value range of S is greater than or equal to 0 and less than or equal to 1. And when the value of S is closer to 1, the corrosion risk of the bolt ball grid rod is greater. E is a real-time environmental parameter, such as temperature, humidity, wind pressure, etc., which is directly obtained through climate and environmental monitoring equipment. k is the proportion of each type of real-time parameter. The type ratio of real-time environmental parameters can be matched according to the actual environment in the area and the material of the bolt ball grid rod to obtain a more accurate environmental parameter impact value, and further improve the accuracy of the corrosion monitoring and evaluation method for analyzing the degree of corrosion of the bolt ball grid rod and the subsequent service life.

[0037] The corrosion risk level is usually affected by the properties of the bolt-ball grid members and the external environment. In some application scenarios, the corrosion risk level of the bolt-ball grid members is calculated by obtaining the basic data of the bolt-ball grid members and the influence values ​​of environmental parameters, including:

[0038] By formula: J = aR SEi bP+cQ, calculate the corrosion risk value. Calculate the bolt ball grid member data separately

[0039] Among them, J is the corrosion risk value of the bolt ball grid rod, a, b, c are the corrosion influence factors, R SEi is the real-time corrosion status value. It is understandable that R SEi It is the result of dimensionless processing obtained by calculating the internal environment value of the bolt ball grid rod. P is the corrosion resistance grade of the bolt ball grid rod, which is determined according to the corrosion resistance grade of the material of the bolt ball grid rod. Among them, when the corrosion resistance grade of the steel is 0.1%, the value of P is 0.1; when the corrosion resistance grade of the steel is 0.2%, the value of P is 0.2... Normally, the corrosion resistance grade of the steel used as the bolt ball grid rod is 0.6%, and the value of P is 0.6.

[0040] Furthermore, the real-time corrosion status value needs to be calculated comprehensively based on the environmental parameters inside the bolt-ball grid rods. In addition, under the influence of temperature and humidity inside the bolt-ball grid rods, the bolt-ball grid rods will also produce electrochemical corrosion. Therefore, in some application scenarios:

[0041] By formula: R SEi=αP+βN+γM+δZ, calculate the real-time corrosion state value, wherein α, β, γ are respectively the preset humidity of the bolt ball grid rod, the oxygen concentration of the real-time environmental parameter and the pressure factor of the real-time environmental parameter, δ is the electrochemical factor of the bolt ball grid rod, α, β, γ, δ are usually preset proportion values, and α+β+γ+δ=1, and the corresponding proportion can be adjusted according to the material of the bolt ball grid rod itself and the actual measured internal environment value; P is the relative humidity in the bolt ball grid rod, which is obtained through the humidity collection end of the corrosion sensor 1; N is the oxygen concentration in the bolt ball grid rod, which is obtained through the oxygen concentration collection end of the corrosion sensor 1; M is the pressure in the bolt ball grid rod, which is obtained through the air pressure collection end of the corrosion sensor 1; Z is the current in the bolt ball grid rod, which is obtained through the current collection end of the corrosion sensor 1.

[0042] In other application scenarios, since the internal environment of the bolt ball grid rod is often fixed at the factory, and in order to simplify the calculation of the real-time corrosion state value and reduce the computing pressure in the server 3, the influence of electrochemical corrosion in the bolt ball grid rod is ignored. At this time, α, β, and γ are taken as 0.5, 0.3, and 0.2 respectively. Therefore, the calculation formula of the real-time corrosion state value is specifically expressed as: R SEi =0.5P+0.3N+0.2M.

[0043] It is understandable that after obtaining the real-time corrosion status value of the bolt ball grid rod, it is necessary to first judge the real-time corrosion status value to obtain the corrosion condition of the bolt ball grid rod in real time, and judge whether it needs to be replaced immediately or the next step of analysis is performed according to the corrosion condition. Therefore, in some application scenarios,

[0044] Step S101: Classify the corrosion status of the bolt ball grid rod into n levels according to the preset corrosion status value, including R1, R2, R3...R n Where n is a positive integer.

[0045] The corrosion risk levels include mild risk state, moderate risk state and severe risk state. Among them, when the corrosion risk level is in mild risk state, the corrosion of the bolt ball grid rods is relatively light, and the bolt ball grid rods can be rust-removed and anti-corrosion treated; when the corrosion risk level is in moderate risk state, the bolt ball grid rods can be painted; when the corrosion risk level is in severe risk state, the corrosion of the bolt ball grid rods is relatively serious, and human participation is required to judge and replace or stop using them according to the actual situation.

[0046] Furthermore, when the corrosion risk level is determined by using the correspondence between the corrosion state level and the real-time corrosion state value, it specifically includes:

[0047] Step S102: When the real-time corrosion state value is less than R1, the bolt ball grid rod is in a non-rusted state. At this time, the bolt ball grid rod does not need to be judged for corrosion risk level, and also does not need any treatment on the bolt ball grid rod. It can continue to be used and wait for subsequent inspection.

[0048] Step S103: When the real-time corrosion status value is greater than R n At this time, the bolt ball grid rods are in a serious rusted state. At this time, the bolt ball grid rods no longer need to be rusted and need to be stopped immediately to avoid serious accidents. At this time, the server 3 sends an early warning message to the management terminal 4 in real time to notify the management personnel and the operating personnel respectively.

[0049] Step S104: When the real-time corrosion status value is greater than R1 and less than R n At this time, the bolt ball grid rods are subjected to corrosion risk level judgment. At this time, the bolt ball grid rods obtained have some corrosion, and it is necessary to judge the corrosion risk level for them, and perform certain treatment on the bolt ball grid rods according to the corrosion risk level judgment results.

[0050] It is understandable that in actual use, the area where the bolt ball grid rods are located is geographically wide, and the installation height of the bolt ball grid rods, the greening of the surrounding areas, and the air environment are all different. Therefore, in some application scenarios, when the bolt ball grid rods are in some buildings with higher requirements, it also includes: obtaining local real-time environmental parameters through the environmental monitoring device 2, and calculating the actual corrosion risk degree value of the bolt ball grid rods with basic numerical values. Among them, the environmental detection device 2 is installed outside the bolt ball grid rod, and the local real-time environmental parameters are used to replace the real-time environmental parameters of the area obtained by the climate environment monitoring equipment connected to the server 3, and the actual corrosion risk degree value of the bolt ball grid rod is calculated, which further improves the accuracy of the corrosion monitoring and evaluation method in evaluating the corrosion state and service life of the bolt ball grid rods in a specific area.

[0051] Furthermore, the local real-time environmental parameters include the location environmental parameters of the bolt ball grid rod and the production location environmental parameters of the bolt ball grid rod. The local real-time environmental parameters are comprehensively analyzed on the server 3, the location environmental parameters and the production location environmental parameters are compared, and the ratio of the environmental parameters is adjusted in time, thereby improving the accuracy of the corrosion monitoring and evaluation method in evaluating the corrosion state and service life of the bolt ball grid rod in a specific area.

[0052] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
