[0080] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0081] Reference Figure 1 - Figure 4As shown, a tunnel shield machine condition monitoring method based on multi-source data includes:

[0082] Conduct on-site surveys on newly built tunnels and collect initial multi-source data of the tunnels, including initial environment information and initial stratum information of the tunnels.

[0083] Based on the analysis of the initial multi-source data of the tunnel, the initial environmental impact factors of the tunnel are obtained;

[0084] Obtaining initial multi-source data of the shield machine under the influence of initial environmental factors of the tunnel, the initial multi-source data of the shield machine includes initial mechanical state information of the shield machine, initial electrical state information of the shield machine and initial posture information of the shield machine;

[0085] Acquire the real-time instruction information of the shield machine and the real-time environmental influencing factors of the tunnel, and obtain the real-time multi-source data of the shield machine under the influence of the real-time environmental influencing factors of the tunnel;

[0086] Based on the analysis of the initial multi-source data and the real-time multi-source data of the shield machine, the shield machine working status alarm index is obtained;

[0087] The working status of the shield machine is evaluated based on the shield machine working status alarm index, and the status of the shield machine is optimized according to the evaluation result of the shield machine working status.

[0088] Specifically, the initial multi-source data of the tunnel are the environmental information and stratigraphic information of the newly built tunnel before the shield machine starts excavating, including the initial environment information of the tunnel and the initial stratigraphic information of the tunnel. The initial environment information of the tunnel is used to describe the climate, hydrology and other environmental conditions before the tunnel construction to ensure the accuracy of the safety measures during the shield machine excavation. The initial stratigraphic information of the tunnel is used to describe the thickness and strength of the soil and rock layers in the area where the tunnel is located to evaluate the impact of geological conditions on the excavation of the shield machine. The initial environmental impact factor of the tunnel is a comprehensive indicator of the impact of the climate inside and outside the newly built tunnel and the soil and rock inside the tunnel on the mechanical and electrical performance of the shield machine. The shield machine working status alarm index is a predictive indicator of possible failures of the shield machine during excavation.

[0089] Furthermore, the newly built tunnel is surveyed on site to collect initial multi-source data of the tunnel, including:

[0090] Acquire the planned area of ​​the new tunnel, and monitor the surface conditions and climate conditions within the planned area of ​​the new tunnel to obtain initial surface information and initial climate information;

[0091] Process the initial surface information and initial climate information to obtain the initial tunnel environment information;

[0092] A pressure sensor is set at the front end of the shield machine to monitor the soil index in front of the shield machine, and obtain the soil initial pressure parameter, soil initial moisture index, soil initial temperature index and soil initial hardness index;

[0093] Displacement sensors and stress sensors are installed on the tunnel wall to monitor the deformation of the tunnel wall and the stress of the tunnel structure, and the initial displacement parameters of the tunnel wall and the initial stress index of the tunnel structure are obtained;

[0094] Data processing is performed on soil initial pressure parameters, soil initial moisture index, soil initial temperature index, soil initial hardness index, tunnel wall initial displacement parameters and tunnel structure initial stress index to obtain tunnel initial stratum information;

[0095] The initial environment information and initial stratum information of the tunnel are integrated to obtain the initial multi-source data of the tunnel.

[0096] Specifically, the planning area for a new tunnel is an area within a certain range where the soil that requires a shield machine for excavation is located. The planned area needs to take into account the influence of surrounding buildings, trees, etc. Therefore, the initial surface information that needs to be considered includes the surface topography, land use, building distribution, underground facility location, and surface settlement and displacement. The initial climate information needs to consider regional precipitation, temperature, humidity and other information, which is helpful to evaluate groundwater level changes and their impact on construction. The temperature will affect the performance of the shield machine and construction materials, especially at extreme temperatures. Humidity affects the moisture content of the soil, which in turn affects the effectiveness of the excavation and support system.

[0097] Furthermore, based on the analysis of the initial multi-source data of the tunnel, the initial environmental impact factors of the tunnel are obtained, including:

[0098] Collecting tunnel historical multi-source data, processing the data in the tunnel historical multi-source data corresponding to the tunnel initial multi-source data, and obtaining tunnel historical environmental information and tunnel historical stratigraphic information;

[0099] Obtain historical fault information of shield machines, and perform fault tree analysis on historical fault information of shield machines and historical multi-source data of tunnels to obtain frequent fault information and multi-source data of common tunnels in different tunnel projects;

[0100] Conduct correlation analysis on the historical fault information of the shield machine and the multi-source data of the common tunnel to obtain the multi-source impact characteristic data of the tunnel;

[0101] Process the multi-source influence characteristic data of the tunnel, and determine the shield machine mechanical performance influence index and shield machine electrical performance influence index based on the tunnel historical environment information and tunnel historical stratum information;

[0102] Conduct data analysis on the shield machine mechanical performance impact index and shield machine electrical performance impact index to obtain the initial environmental impact factor of the tunnel;

[0103] Specifically, the shield machine mechanical performance impact index is a comprehensive indicator of the impact of the environment and strata in the area where the new tunnel is located on the shield machine's mechanical performance. The shield machine electrical performance impact index is a comprehensive indicator of the impact of the environment and strata in the area where the new tunnel is located on the shield machine's electrical performance. For example, extreme temperature (too high or too low) may affect the viscosity of the shield machine's hydraulic oil, causing the performance of the hydraulic system to deteriorate. High humidity environment may cause short circuits or corrosion of electrical equipment and control systems, affecting the reliability of the equipment. Different types of soil (such as clay, sand, pebbles, etc.) will have different effects on the shield machine's propulsion force, excavation speed and cutterhead wear.

[0104] The specific steps of performing fault tree analysis on the historical fault information of the shield machine and the historical multi-source data of the tunnel to obtain frequent fault information include:

[0105] S1: Collect historical data of failures of shield machines during tunnel excavation, including failure records of shield machines and various data during tunnel construction, such as equipment logs, maintenance records, environmental data, etc.

[0106] S2: Establish a fault tree model to decompose the fault event into more basic events and identify potential fault causes;

[0107] S3: Identify the frequency and pattern of various types of failures through statistical analysis;

[0108] S4: Identify the main factors that lead to frequent failures, such as equipment design defects, operating errors, environmental conditions, etc.

[0109] In step S2, the steps of establishing the fault tree model include:

[0110] S21: Identify the main problem or top-level event of the fault tree, such as "shield machine failure";

[0111] S22: Identify the main cause of the top-level event, such as "power system failure" or "hydraulic system problem";

[0112] S23: Further decompose the main fault cause into secondary events, for example, "power system failure" may be decomposed into "engine overheating" or "fuel supply problem";

[0113] S24: Use logic gates (AND, OR) to connect these events and describe the relationship between them. For example, if "engine overheating" and "fuel supply problem" can both cause "power system failure", connect them with an OR gate.

[0114] S25: Decompose secondary events into primary events, which are the most basic events that can be directly observed or recorded, such as "cooling system failure" or "fuel pump failure";

[0115] S26: Verify the accuracy and completeness of the fault tree model to ensure that all possible fault paths are covered and modified based on the actual data collected;

[0116] Among them, the calculation formula of the shield machine mechanical performance influence index is:

[0117] ;

[0118] In the formula, is the shield machine mechanical performance influence index, To adjust the scale factor of the formula, is the empirical coefficient of the influence of tunnel wall displacement parameters on the mechanical properties of the shield machine, is the empirical coefficient of the influence of tunnel structure stress index on the mechanical properties of shield machine, is the empirical coefficient of the influence of soil pressure parameters on the mechanical properties of the shield machine, is the empirical coefficient of the influence of soil hardness index on the mechanical properties of shield machine, is the empirical coefficient of the influence of soil temperature index on the mechanical properties of shield machine, is the empirical coefficient of the influence of soil moisture index on the mechanical properties of shield machine, For the Soil pressure parameters of the day, For the Soil hardness index of the day, For the Soil temperature index for the day, For the Soil moisture index for the day, For the The tunnel wall displacement parameters of the day, is the tunnel wall position parameter on the first day, and They are reference pressure, reference hardness, reference temperature and reference humidity respectively;

[0119] The calculation formula of the shield machine electrical performance impact index is:

[0120] ;

[0121] In the formula, is the shield machine electrical performance impact index, To adjust the scale factor of the formula, and are weight coefficients, , , , , and They are the soil pressure parameters, soil moisture index, soil temperature index, soil hardness index, tunnel wall position parameters and tunnel structure stress index of the newly built tunnel on the first day. For the Tunnel structure stress index of the day;

[0122] The calculation formula of the initial environmental impact factor of the tunnel is:

[0123] ;

[0124] In the formula, is the initial environmental impact factor of the tunnel, is a quadratic function, and There is a positive correlation.

[0125] It is understandable that the higher the values ​​of soil pressure parameters, soil moisture index, soil temperature index, etc. of the new tunnel that the shield machine needs to excavate, the greater the value of the shield machine's mechanical performance index. Because some specific mechanical parts of the shield machine, such as the cutterhead and other mechanical parts, will wear out over time during the excavation work, it is necessary to consider the total value of the soil pressure parameters, soil hardness index, etc. every day during the excavation period. The electrical components of the shield machine are not prone to wear and tear over time, and some electrical properties of the electrical components of the shield machine will gradually return to normal after the shield machine stops working, or even The environment inside the tunnel may improve the electrical performance of the shield machine. Therefore, only the difference between the soil pressure parameters, soil moisture index, etc. of the shield machine every day during the excavation period and the shield machine on the first day of work can be considered. The larger the absolute value of the difference, the greater the shield machine electrical performance impact index. However, the larger the absolute value of the difference between the tunnel wall position parameters and the tunnel structure stress index of each day during the excavation period and the shield machine on the first day of work, the smaller the shield machine electrical performance impact index, because the larger the absolute value of the difference between the tunnel wall position parameters and the tunnel structure stress index, the better its electrical performance will be, and it will not be easily affected by these data.

[0126] Furthermore, the initial multi-source data of the shield machine under the influence of the initial environmental impact factors of the tunnel are obtained, including:

[0127] Use monitoring equipment to obtain the mechanical status information of the shield machine foundation and the electrical status information of the shield machine foundation;

[0128] The mechanical state information of the shield machine foundation and the electrical state information of the shield machine foundation are evaluated respectively to obtain the mechanical state index of the shield machine foundation and the electrical state index of the shield machine foundation;

[0129] The shield machine foundation mechanical state index is associated with the shield machine mechanical performance influence index to obtain the shield machine initial mechanical state index;

[0130] The shield machine foundation electrical status index is associated with the shield machine electrical performance impact index to obtain the shield machine initial electrical status index;

[0131] Establish a three-dimensional coordinate system with the shield machine as the center point, and obtain the initial posture parameters of the shield machine;

[0132] The initial mechanical state index, initial electrical state index and initial attitude parameters of the shield machine are integrated and data processed to obtain the initial multi-source data of the shield machine.

[0133] Furthermore, the real-time instruction information of the shield machine and the real-time environmental influencing factors of the tunnel are obtained, and the real-time multi-source data of the shield machine under the influence of the real-time environmental influencing factors of the tunnel are obtained, including:

[0134] Collect real-time surface information and climate information, and process the data to obtain real-time tunnel environment information;

[0138] Correlate the tunnel real-time multi-source data and the tunnel initial environmental impact factor to obtain the tunnel real-time environmental impact factor;

[0139] Based on the real-time environmental impact factors, the initial posture information of the shield machine, the mechanical status information of the shield machine foundation and the electrical status information of the shield machine foundation, the real-time multi-source data of the tunnel shield machine is obtained.

[0140] Specifically, the tunnel real-time environmental impact factor is obtained by the tunnel real-time multi-source data and the tunnel initial environmental impact factor through the calculation formula of the tunnel initial environmental impact factor.

[0141] Furthermore, based on the analysis of the initial multi-source data of the shield machine and the real-time multi-source data of the shield machine, the shield machine working status alarm index is obtained, including:

[0142] Obtain the real-time mechanical status information and electrical status information of the shield machine from the real-time multi-source data of the shield machine;

[0143] Obtain the real-time mechanical state index of the shield machine and the real-time electrical state index of the shield machine in the real-time mechanical state information of the shield machine and the real-time electrical state information of the shield machine;

[0146] Based on the shield machine mechanical fault alarm value and the shield machine electrical fault alarm value, the shield machine working status alarm index is obtained.

[0147] Specifically, the shield machine basic mechanical condition index is a comprehensive indicator used to evaluate the operating status and health level of the shield machine. It reflects the overall working condition of the shield machine by comprehensively considering the performance, wear and working efficiency of multiple mechanical components, such as the degree of component wear, measuring the wear of key components such as the cutterhead, cutter, screw conveyor, including the wear rate and current wear amount, the propulsion speed of the shield machine, cutting efficiency and overall working efficiency, etc. The shield machine basic electrical condition index is used to evaluate the health and operating status of the shield machine electrical system. It comprehensively considers the performance and status of each component of the electrical system to reflect the reliability and efficiency of the overall electrical system, such as the health of electrical components, and evaluates the operating status and performance of electrical components such as motors, inverters, and controllers; Power supply stability, monitoring the stability and quality of power supply, such as voltage fluctuations and power outages.

[0148] Furthermore, the working state of the shield machine is evaluated based on the shield machine working state alarm index, and the state of the shield machine is optimized according to the evaluation result of the shield machine working state, including:

[0152] The shield machine working status assessment information is used as the shield machine working status assessment result to optimize the shield machine status.

[0153] Specifically, the shield machine working status alarm index can be obtained by setting the unit time according to the excavation period during the tunneling work of the tunnel shield machine. In order to ensure that the monitoring system analyzes the working status of the shield machine more accurately, the unit time can be set to one minute or shorter. Although this will increase the load of the unit operation system, when calculating the shield machine mechanical performance impact index, the shield machine electrical performance impact index and the tunnel real-time environmental impact factor, the number of times the monitoring module collects the initial multi-source data of the tunnel and the real-time data of the tunnel will increase. However, in a day, the real-time surface information and the real-time climate information usually do not change so quickly, especially the real-time surface information is difficult to change during tunnel construction. The number of times the monitoring module collects the initial multi-source data of the tunnel and the real-time data of the tunnel can be reduced, the load of the monitoring system can be reduced, and the efficiency of the monitoring system in analyzing the working status of the shield machine can be improved.

[0163] The tuning unit is used to optimize the state of the shield machine according to the evaluation result of the working state of the shield machine.
