Description

Technical Field

[0001] The present invention relates to the technical field of engineering surveying and mapping, and in particular to a tunnel surveying and mapping method, electronic equipment and system. Background Art

[0002] The common method for surveying and mapping tunnels is to use the infrared laser reflection principle to measure relative coordinates and convert absolute coordinates. If there are temporary obstructions in the surveying and mapping space (exhaust ducts, temporary earthworks, stepped steps, etc.), the surveying and mapping data will be distorted and require subsequent manual deduction or adjustment calculations, which will prevent the full use of the instrument's automatic surveying and scanning function to collect real-time data.

[0003] Specifically, the existing technical solutions require local surveying and mapping, manual statistics and summary, and the interference data needs to be eliminated in the case of local obstacles. Based on this, the tunnel over-excavation and under-excavation surveying and mapping has evolved into a local quality data spot check, which cannot be used as a relatively real tunnel over-excavation and under-excavation surveying and mapping data. The over-excavation depth is measured locally, and the average over-excavation value is roughly calculated. The arc length of the design curve is used as the long side of the rectangle, the average value of the local sampling data is used as the width, and the over-excavation area is calculated by multiplying the length by the width. The excavation advance distance is compared with the calculation and control of the tunnel over-excavation and under-excavation accuracy based on this. The accuracy and precision are relatively rough, resulting in low tunnel surveying and mapping accuracy. Summary of the invention

[0055] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 those skilled in the art without creative work are within the scope of protection of the present invention.

[0056] For the purpose of the following description, the professional terms involved in the embodiments of the present invention are described as follows:

[0057] Mileage: Based on the mileage of the surveying and mapping analysis platform, the instrument scans the data, corresponds to the standard mileage segment, removes the data in the overlapping mileages, and takes the data based on the system mileage segment;

[0058] Number of cycles: With the working surface as the first dimension, the starting mileage is set for each interval, and the cycle is automatically sorted and set. Manual adjustment is supported, and subsequent cycles are automatically adjusted;

[0059] Surrounding rock grade: select through the drop-down menu on the surveying and mapping equipment interface, including but not limited to I, II, III, IV, V, VI;

[0060] Excavation methods: including but not limited to full section, step method, core soil excavation method, CD excavation method, CRD excavation method, double side wall excavation method;

[0061] Allowable over-excavation area: set according to the needs of the construction company.

[0062] It should be noted that in the tunnel surveying method provided by the embodiment of the present invention, the current surveying data collected by the surveying equipment is the surveying data obtained by the current surveying cycle. During the tunnel construction process, multiple surveying cycles are required, and the current surveying data collected by each surveying cycle is used to analyze the current surveying results. Among them, the current surveying results include but are not limited to the over-break area, the maximum over-break area, and the like.

[0063] On the basis of obtaining the current surveying and mapping results, the current surveying and mapping data can also be used to analyze the construction status and obtain the current construction status. As mentioned above, multiple surveying and mapping cycles are required during the construction of the tunnel. The current construction status obtained in each surveying and mapping cycle is used to guide the construction strategy of the next surveying and mapping cycle, so as to adjust the construction strategy in a timely manner.

[0064] According to an embodiment of the present invention, an embodiment of a tunnel surveying method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0065] In this embodiment, a tunnel mapping method is provided, which can be used in electronic equipment, such as a mapping analysis platform, etc. Figure 1 is a flow chart of a tunnel mapping method according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0066] S11, obtaining current surveying and mapping data of each working face of the target tunnel and design data of each working face.

[0067] The working faces of the target tunnel include excavation, primary support, invert and secondary lining. The current surveying and mapping data of each working face is collected by using surveying and mapping equipment. For example, by setting the current surveying and mapping working face in the surveying and mapping equipment and starting the work of the surveying and mapping equipment, the current surveying and mapping data of the current surveying and mapping working face can be obtained. Specifically, in order to effectively control the over-excavation and under-excavation of the tunnel, the user sets the XYZ coordinate values ​​in the surveying and mapping equipment, that is, the longitudinal and transverse coordinates (x, y) of the section and the mileage coordinates (z) of the excavation excavation direction, and surveys the working faces in sequence, excavation surveying, primary support surveying, invert surveying, and secondary lining surveying. The surveying and mapping working faces are from larger radius to smaller radius in sequence. The surveying and mapping working face is selected, the number of section surveying and mapping points is set, the surveying and mapping cycle mileage is set, and the number of sections to be surveyed in the cycle is set. The surveying and mapping equipment automatically surveys and maps, thereby obtaining the current surveying and mapping data of each working face.

[0068] Before the construction of the target tunnel, a BIM model needs to be designed. Based on this, the electronic device can analyze the BIM model of the target tunnel to obtain the design data of each working surface. Alternatively, the design data of each working surface is obtained by the electronic device from other devices, and the source of the design data is not limited here.

[0069] S12, adjusting the preset distance inward based on the design data of each working surface to determine the static value surveying area.

[0070] Among them, the data of the static value surveying area is a preset value.

[0071] The preset distance is set according to actual needs. For example, considering the maximum undercut, the second lining is scaled down by 10 cm based on the minimum radius. For each working surface, the electronic equipment adjusts 10 cm inward based on its design data, and determines the area enclosed by the adjusted curve and the ground as the static value mapping area.

[0072] For the static value surveying area, in the subsequent calculation process of the surveying results, the corresponding value is a preset value, that is, a fixed value. During the excavation of the target tunnel, some temporary earthworks or temporary piled objects will inevitably appear, and these objects need to be removed when calculating the surveying results. Based on this, in this embodiment, by setting the value of the static value surveying area to a fixed value, the value will not change with the change of temporary objects in the tunnel, thereby avoiding the influence of the pile of temporary objects on the surveying results.

[0073] Figure 2 The schematic diagram of the current working surface displayed on the surveying and mapping interface is shown. The design curve of the current working surface is a regular semicircular arc on the outside. The current surveying and mapping curve obtained based on the current surveying and mapping data is an irregular line graph. The static value surveying and mapping area is obtained by adjusting the preset distance inward based on the design curve. Figure 2The area surrounded by the irregular line graph in the lower right corner can be considered as temporary piles in the tunnel. This part of the data needs to be removed in the subsequent calculation of the surveying and mapping results. Therefore, the concept of static value surveying interval is introduced in this embodiment, and the data in this interval is set to a preset value. Among them, a setting range of preset values ​​can be set in the electronic device, and the user adjusts the setting range according to actual needs to obtain the preset value corresponding to the current surveying and mapping work surface.

[0074] This step will be analyzed in detail below.

[0075] S13, performing surveying calculations based on the current surveying data and the data of the static value surveying area to determine the current surveying results of each working surface.

[0076] The electronic device uses the data of the static value surveying area to replace the values ​​in the corresponding area, that is, static value replacement, and then uses the current surveying data and the static value surveying area replaced with the preset value to perform surveying calculations to determine the current surveying results of the current working surface. For example, calculate the over-excavation area of ​​the current working surface, etc. The specific surveying results that need to be obtained are set according to actual needs, and there is no limitation on them here.

[0077] As for the calculation process of surveying and mapping results, which involves the calculation content of geometric analysis, there is no limitation on its calculation method again, and it can be set according to the actual situation.

[0078] This step will be analyzed in detail below.

[0079] The tunnel surveying method provided in this embodiment adjusts the preset distance inward based on the design data of each working surface, and sets the data of the static value surveying area to the preset value, so as to eliminate the influence of some factors such as exhaust pipes and eliminate the influence of temporary earthworks in the surveying area on the surveying results. By shrinking and setting the preset value, interference factors in the surveying area are automatically eliminated, thereby improving the accuracy of the current surveying results.

[0080] In this embodiment, a tunnel mapping method is provided, which can be used in electronic equipment, such as a mapping analysis platform, etc. Figure 3 is a flow chart of a tunnel mapping method according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0081] S21, obtaining current surveying and mapping data of each working face of the target tunnel and design data of each working face.

[0082] For details, please see Figure 1 S11 of the illustrated embodiment will not be described in detail here.

[0083] S22, adjusting the preset distance inward based on the design data of each working surface to determine the static value surveying area.

[0084] Among them, the data of the static value surveying area is a preset value.

[0085] Specifically, the design data includes a design curve, the current surveying and mapping data includes a current surveying and mapping curve, and the above S22 includes:

[0086] S221, adjusting the design curve of each working surface by a preset distance in the direction of the road surface dividing line to determine the static value dividing curve.

[0087] The electronic equipment determines the design curve of the working surface and the road surface dividing line, and adjusts the design curve to the direction of the road surface dividing line by a preset distance as a static value dividing curve.

[0088] For the area enclosed by the design curve, above the horizontal road surface baseline, the normal fixed value; individual temporary mutation values ​​(for example, emergency widening channels), only the current cycle statistics are performed, and no overall mean comparison is performed. For the arc length of the design curve, above the horizontal road surface baseline, the semi-circular arc, the normal fixed value; individual temporary mutation values ​​(for example, emergency widening channels), only the current cycle statistics are performed, referring to the semi-circular arc part above the horizontal road surface, and no overall mean comparison is performed.

[0089] S222, determining a static value surveying area based on an area formed by the static value boundary curve and the road surface boundary line.

[0090] Within the static curve, the horizontal line of the road surface is the downward line, and the area between these two lines is the static value surveying area. As long as the current surveying data of the surveying surface is measured under the condition of line of sight, the part within the static value surveying area can be calculated by using the preset value replacement principle to avoid the influence of exhaust pipes and temporary obstacles on the measurement results. In order to be suitable for multi-scenario applications, the horizontal road surface is used as the dividing line, and the part above the road surface and the part below the road surface can be used, so that both the design with inverted arch and the design without inverted arch can be used.

[0091] For example, taking the excavation working face as an example, the design face scale of the second lining is 10 cm (excavation, primary support, and second lining are all on its larger radius) as the static value boundary curve, and the measured curve area minus the static value boundary curve area is used to avoid the influence of the step method and the actual closed curve measured with obstacles. The full section, step, CR\CRD different methods, for segmented spraying and segmented measurement, all refer to the reference curve for comparison, and accumulate the statistics of different working faces of different times. The road surface horizontal line is used as the division and cutting of the upper and lower parts. The excavation, primary support, and second lining are all compared with the part above the horizontal road surface line, and the static value area of ​​the part above the horizontal line is deducted to form a circular fan. For the invert part, the static value of the part below the horizontal line is deducted. The invert part is fixed and easier to control. For some sections with good surrounding rock mileage, there is no invert and it is directly used as a horizontal roadbed surface.

[0092] S23, performing surveying calculations based on the current surveying data and the data of the static value surveying area to determine the current surveying results of each working surface.

[0093] Specifically, the above S23 includes:

[0094] S231, displaying the design curve, the current surveying curve and the static value surveying area on the surveying interface.

[0095] like Figure 4 As shown, the surveying and mapping interface includes a curve display area and a surveying and mapping result display area. The curve display area is used to display the design curve, the current surveying and mapping curve and the static value surveying and mapping area, and the surveying and mapping result display area is used to display the calculated surveying and mapping results.

[0096] exist Figure 4 In the surveying and mapping interface shown, the area beyond the design area is the over-excavation area; the hollowed-out area between the design curve and the static value surveying and mapping area is the under-excavation area; the area enclosed by the current surveying and mapping curve within the static value surveying and mapping area is the ignored area, because it is ignored within the static value surveying and mapping area and does not participate in the calculation of the under-excavation area.

[0097] S232, in response to the selection result of the surveying and mapping calculation area on the surveying and mapping interface, determining a target surveying and mapping calculation area.

[0098] The target surveying and calculating area includes the design curve, the current surveying and calculating curve and the static value surveying and calculating area.

[0099] The surveying and mapping interface is an interactive interface, on which the user makes selections, such as box selection, to obtain the target surveying and mapping calculation area. Figure 4 The area enclosed by the dotted frame in . After the dotted frame is formed by selection, the dotted frame is adjustable and can be adjusted according to actual needs.

[0100] When the user wants to ignore the calculation of various data in a certain area, a target surveying and calculation area can be set, and only the data in the data collection area will participate in the calculation. For example, click and hold the left mouse button on the surveying and mapping interface, and then drag a dotted rectangle. After releasing the mouse, the current various calculation results will be updated synchronously according to the current rectangular frame, static data collection range, etc. If you want to further adjust the size and position of the dotted box, move the mouse cursor to the 8 small squares around it. At this time, the cursor will deform and change the size by dragging. When the mouse moves to the inside of the dotted box, the cursor becomes a cross, and it supports dragging the entire dotted box to a new position.

[0101] like Figure 4 As shown in the figure, the over-excavation area at the bottom is ignored because it is not included in the rectangular frame. Figure 4 The area beyond the road dividing line in the lower left corner. At the same time, the large under-break area at the bottom before, because this area is in the static value surveying area, not only does it not participate in the area calculation at this time, but also the calculation of over-break and under-break is ignored. Specifically, ignore everything outside the dotted box (ignore the over-break and under-break of the measuring points outside the dotted box, ignore the area of ​​intersection with the design curve, and ignore the area of ​​intersection with the measured curve). The static value surveying area designed later only ignores the under-break of the measuring point, forms a graphical union with the measured curve, and ignores the under-break area. The static value surveying boundary line is set to avoid under-break outside the arc (if any measuring point falls within the static value arc) (the maximum under-break will not be lower than the preset distance); but the over-break phenomenon outside the arc needs to be counted. It is only in the static value surveying interval above the ground route, that is, above the horizontal axis, that is, the over-break and under-break of the ground of the measuring point, which are replaced by static and are not considered.

[0102] S233, extracting data within the target surveying and mapping calculation area and calculating the current surveying and mapping result based on the extracted data.

[0103] After determining the target surveying and calculating area, the electronic device extracts the data in this area, including the current surveying and calculating data in the target surveying and calculating area and the preset value of the static surveying and calculating area. Based on the extracted data, the electronic device calculates the current surveying and calculating result according to the corresponding calculation principle.

[0104] In some optional implementations, the above step S233 of calculating the current surveying and mapping result based on the extracted data includes:

[0105] (1) Calculate the first area based on the current surveying curve of each working surface within the target surveying calculation area.

[0106] (2) Calculate the current surveying result based on the first area and the preset value corresponding to the static value surveying area.

[0107] For each working surface, the electronic device uses the current surveying curve in the target surveying calculation area to calculate the area of ​​the area enclosed by the current surveying curve and the road surface dividing line to obtain the first area. After obtaining the first area, the electronic device combines the preset value corresponding to the static value surveying area. If the preset value is the area of ​​the static value surveying area, the electronic device uses the difference between the first area and the area of ​​the static value surveying area to determine the current surveying result. For the static value surveying area, the current surveying result is calculated directly using the preset value, which improves the reliability of the current surveying result.

[0108] Specifically, the final output of the current surveying and mapping results can be output in the form of reports:

[0109] For the excavation working face, the area enclosed by the measurement curve is calculated by taking the aggregate mean of the cycle segment, querying the report by mileage, taking the data source value within the corresponding mileage, and measuring the actual value of the fan-shaped section (above the horizontal line, deducting the reference static value) + reference static value; for the over-excavation area, compare the static value curve area, take the aggregate mean of the cycle segment, query the report by mileage, and take the data source value within the corresponding mileage; for the under-excavation area, compare the static value curve area, take the aggregate mean of the cycle segment, query the report by mileage, and take the data source value within the corresponding mileage; the maximum over-excavation is the maximum value; the maximum under-excavation is the maximum negative value; the linear over-excavation average is taken within the cycle, and the report is queried by mileage, taking the data source value within the corresponding mileage to meet the core data report output of the existing traditional business reports; the excavation volume above the road surface is the measurement curve area * excavation footage; the amount of detonators and the amount of blasting powder are obtained through input.

[0110] For the initial support working surface, the design area is a normal fixed value. For individual temporary mutation values ​​(for example, emergency widening channels), only the current cycle statistics are performed, and no overall mean comparison is performed; the fan area within the smaller radius of the design curve is a normal fixed value, which comes from the drawing. The design of the initial support is a circular fan, and this value refers to the fan part within the arc of the smaller radius to the horizontal line of the road surface; the design spraying concrete volume is the area of ​​the initial support design curve * footage; the curve area is measured and compared with the static value curve area, the aggregate mean is taken for the cycle segment, and the report is queried by mileage, and the data source value within the corresponding mileage is taken. Among them, the current surveying and mapping results also include the measurement of the required spraying concrete volume, the actual spraying concrete volume, the concrete ticket volume, the rebound volume, the rebound rate, the actual consumption / design spraying concrete volume, the required spraying concrete volume / design spraying concrete volume, the loss reduction coefficient, etc.

[0111] For the secondary lining working surface, the design area is a normal fixed value. For individual temporary mutation values ​​(for example, emergency widening channels), only the current cycle statistics are performed, and the overall mean is not compared with the design quantity, that is, the secondary lining design area * footage; the fan area within the smaller radius of the design curve is a normal fixed value, which comes from the drawing. The initial support of the design is a circular fan, and this value refers to the fan area within the smaller radius arc to the part above the road surface horizontal line; the design quantity is the secondary lining design area * cycle length; the curve area is measured and compared with the static value curve area, the cycle section takes the aggregate mean, and the report is queried by mileage, and the data source value within the corresponding mileage is taken. Among them, the current surveying and mapping results also include the measurement of the required secondary lining concrete volume, the concrete ticket volume, the actual consumption / designed secondary lining volume, the measurement of the required secondary lining concrete volume / designed secondary lining volume, and the loss reduction coefficient, etc.

[0112] For the invert working face, the design area is taken according to the cycle mileage. If the surrounding rock grade changes within the mileage, the invert scheme may be different; the design volume is the design invert area * footage; the measurement curve area can be averaged by the section; the excavation volume below the road surface is the measurement curve area * cycle length. Among them, the current surveying and mapping results also include the measurement of required concrete volume, concrete ticket volume, actual consumption / design volume, measurement of required concrete volume / design volume, and loss reduction coefficient, etc.

[0113] The tunnel surveying method provided in this embodiment determines the static value surveying area based on the road surface dividing line, that is, during the surveying and mapping calculation, the road surface dividing line is used to distinguish the part above the road surface and the part below the road surface, and the static value surveying area is clearly divided, thereby ensuring the reliability of the current surveying and mapping results determined subsequently. The design curve, the current surveying and mapping curve, and the static value surveying and mapping area are displayed on the surveying and mapping interface, which facilitates the accurate determination of the surveying and mapping calculation area. Within the accurate surveying and mapping calculation area, the corresponding data in the area can be extracted, thereby ensuring the accuracy of the extracted data.

[0114] In this embodiment, a tunnel mapping method is provided, which can be used in electronic equipment, such as a mapping analysis platform, etc. Figure 5 is a flow chart of a tunnel mapping method according to an embodiment of the present invention. Figure 5 As shown, the process includes the following steps:

[0115] S31, obtaining current surveying and mapping data of each working face of the target tunnel and design data of each working face.

[0116] S32, adjusting the preset distance inward based on the design data of each working surface to determine the static value surveying area.

[0117] Among them, the data of the static value surveying area is a preset value.

[0118] S33, performing surveying calculations based on the current surveying data and the data of the static value surveying area to determine the current surveying results of each working surface.

[0119] It should be noted that for detailed description of S31-S33, please refer to Figure 3 The description of S21-S23 of the illustrated embodiment will not be repeated here.

[0120] S34, analyzing the current surveying and mapping results of each working face to determine the current construction status of each working face.

[0121] For each working surface, the electronic device compares and analyzes the current surveying and mapping results with the design values ​​to obtain the current construction status of each working surface, wherein the current construction status includes but is not limited to the construction progress, the summary loss coefficient and the rebound coefficient.

[0122] In some optional implementations, the current surveying and mapping result includes an identifier of the current surveying and mapping position, and the above S34 includes:

[0123] (1) Extract the construction design value corresponding to the current surveying location based on the identification.

[0124] (2) Compare and analyze the construction design values ​​with the current surveying and mapping results to determine the current construction status of each working surface.

[0125] Specifically, the identification of the current surveying and mapping position can be identified by mileage and pile number, or by other forms of identification, which are not limited here. When the surveying and mapping equipment collects data for the current surveying and mapping position, the mileage and pile number of the current surveying and mapping position are recorded; accordingly, when designing the target tunnel, there are corresponding construction design values ​​corresponding to the mileage and pile number. Based on this, the electronic equipment can use the mileage and pile number to match the construction design value with the surveying and mapping value, so as to conduct subsequent comparative analysis and determine the current construction status of each working surface.

[0126] The current surveying and mapping results include the identification of the current surveying and mapping position, which can be used to extract the construction design value, and automatically realize the automatic comparison and analysis between the construction design value and the current surveying and mapping results, saving human resources and improving the efficiency and accuracy of the current construction status analysis.

[0127] For example, when the current surveying and construction results are output, the cycle and mileage statistics table is automatically output, and the situation of each cycle process can be effectively analyzed. Among them, the cycle and mileage statistics table provides query by cycle, or query by mileage. The statistical data displayed in the statistical table are but not limited to: over-excavation and under-excavation surveying and mapping big data; segmented analysis of excavation, primary support, invert and secondary lining; measurement of required concrete volume to accurately estimate the concrete consumption of the next cycle; actual consumption, that is, actual consumption of primary support invert, secondary lining and invert; design volume, that is, real-time tracking and calculation based on BIM model mileage; rebound volume, that is, instrument surveying and ticket verification; rebound rate; loss coefficient; comparison of longitudinal excavation plan, blasting powder consumption, and surrounding rock grade; comprehensive comparative analysis of unit excavation; output of intuitive economic and frugal data indicators.

[0128] S35, displaying the current construction status of each work surface on the construction analysis interface.

[0129] like Figure 6b As shown, the current construction status includes but is not limited to construction progress, main economic index curves, reasons for delay, and analysis of reasons for over-excavation and under-excavation, etc. By setting the design data reasonably, the measured data is truly collected and fed back, and the calculated data reflects the work effect in real time. Evaluation indicators include but are not limited to the allowable over-excavation area, the actual concrete consumption ratio, the man-hour saturation rate, and the comparison of the accumulated over-concrete consumption. Through these indicators, the management and process levels can be accurately evaluated, the trend of problem occurrence can be determined, and the laws behind the problems can be discovered.

[0130] In some optional implementations, the current construction status includes the current construction progress, and the above S35 includes:

[0131] (1) The progress of the construction design of the working surface is displayed in the progress area of ​​the construction analysis interface.

[0132] (2) The current construction progress is displayed superimposed on the construction design progress.

[0133] The construction design progress is a fixed value determined before construction. The current construction progress is unpredictable and is obtained through analysis of current surveying and mapping data. By superimposing the current construction progress on the construction design progress and comparing the current construction progress with the construction design progress, it is possible to determine whether the current construction progress is ahead of schedule or behind schedule, etc. By superimposing the current construction progress on the construction design progress, dynamic control and display of the construction progress can be achieved.

[0134] The tunnel surveying method provided in this embodiment can automatically derive the current construction status of each working face by analyzing the current surveying results of each working face, and display the current construction status on the construction analysis interface, so that users can intuitively understand the current construction status and adjust the construction strategy in time, thereby greatly saving the construction investment of the target tunnel. The tunnel surveying method mainly includes four parts, namely BIM design data, progress cycle dynamic control, instrument actual measurement and overall analysis. Among them, progress cycle dynamic control corresponds to the display analysis of the current construction progress mentioned above; instrument actual measurement corresponds to the current surveying data of the surveying instrument mentioned above; overall analysis corresponds to the output of various reports mentioned above, such as Figure 6a as well as Figure 6b shown.

[0150] The embodiment of the present invention also provides a tunnel mapping system, such as Fig. 9 As shown, it includes: a surveying and mapping device 10 and an electronic device 20, and the electronic device 20 is connected to the surveying and mapping device 10. The surveying and mapping device 10 is used to measure the current surveying and mapping data of each working surface of the target tunnel; the electronic device 20 is used to communicate with the surveying and mapping device 10. The surveying and mapping equipment includes but is not limited to a profiler, a total station, a three-dimensional scanner, a drone surveying and mapping, a three-arm trolley control system, and the like.

[0151] Specifically, surveying and mapping equipment is used for automatic surveying and mapping, and the mileage coordinate information is matched. When there is a surveying and mapping work surface, one outdoor measurement operation can be used to perform surveying and mapping operations on several different surveying and mapping work surfaces. With a network environment, the surveying and mapping data can be submitted to the electronic device with one click. The electronic device connects to the work point, surveying and mapping work surface, and mileage of the uploaded surveying and mapping data, automatically classifies and calculates statistics, automatically outputs relevant reports and core data, and summarizes the loss coefficient and rebound coefficient for the next cycle control. The electronic device accumulates experience values ​​and combines them with the current excavation surface to accurately calculate the planned material lifting volume for the next cycle.

[0152] The tunnel surveying and mapping system provided in this embodiment realizes automatic tunnel surveying and mapping, one-click upload, and automatic report generation. The core data of the report guides on-site production construction and business management and control, effectively controls the common problems of tunnel over-excavation and under-excavation, solves industry difficulties, improves the industry's average digitalization level and intelligent popularization, and brings significant economic benefits to the industry's tunnel over-excavation and under-excavation management.

[0153] As a specific application example of the surveying and mapping system, it includes:

[0154] (1) The drop-down selection of the surveying and mapping equipment can correspond to the tunnel work point information and ID given by the platform system;

[0155] (2) Input the Z mileage coordinates, X-axis deviation distance, and Y elevation value given by the total station at the surveying equipment installation point;

[0156] (3) The surveying and mapping equipment sets the working surface for surveying and mapping (excavation, primary support, invert, secondary lining), and imports the design curves of different working surfaces. The electronic equipment has model vector data and supports exporting the design curves to the surveying and mapping equipment, or the surveying and mapping equipment only transmits absolute coordinates, and the comparison calculations are all implemented in the electronic equipment.

[0157] For example, it is only necessary to make initialization settings for the tunnel project (work site, starting mileage, surrounding rock grade, excavation method), the number of cycles and current cycle tracking, which are management unit means, and are variables floating above the tunnel initialization information with mileage as the dominant information. In the future, it is only necessary to track the current cycle information, and the data information uploaded by the surveying and mapping equipment will be automatically matched to the corresponding mileage (the excavation method, surrounding rock grade, and design data corresponding to the mileage are all relatively fixed values, and the surrounding rock can be adjusted in time if it is temporarily different from the detection). The number of cycles and the specific starting mileage of the current cycle are management variables, similar to vernier calipers, which make unidirectional tracking adjustments on the relatively fixed tunnel information axis, and the subsequent cycles follow the linkage. In this way, tunnel initialization is concentrated on one-time maintenance at the beginning of the project, and the current cycle tracking and uploading of instruments and equipment on different working faces are summarized in the intermediate process. There is no need to do additional manual entry and reporting for other things. The logic is simple and clear, avoiding unclear business, no way to start operation, and unclear where to report and maintain. It is presented to customers with the simplest and clearest logic, which can realize the core value of informatization. Specifically, iterations can be performed based on the following steps: the first step is to realize centralized initialization of tunnel projects and optimize the existing architecture; the second step is to track the cyclic progress of the working face, first manually fill in and track the current progress, similar to a vernier caliper, sliding on the mileage information scale, and then consider connecting various types of excavation trolleys, secondary lining trolleys, arch hydraulic trestles, maintenance trolleys and other IoT tracking and positioning devices of the project; the third step is to gradually achieve the construction of tunnel entity models (local widening, drainage ditches, cable trenches, turning diameter changes), and the value and comparison of various design curves, and directly obtain data from the parametric model; the fourth step: the tunnel image progress tracking data is fed back to the parametric model to form an intuitive BI dashboard to understand the real-time progress of each working face of the tunnel and the comprehensive economic indicators;

[0158] (4) The surveying and mapping equipment can set the number of surveying and mapping nodes in the current section and the number of surveying and mapping sections in the depth direction (the denser the number of points and the greater the number of sections, the closer the measured volume quantities are to the real vector data);

[0159] (5) The surveying and mapping equipment automatically surveys and maps, and the corresponding mileage coordinate information is matched. When there is a surveying and mapping work surface, one outdoor actual measurement operation can be used to conduct surveying and mapping operations on several different surveying and mapping work surfaces. With a network environment, the surveying and mapping data can be submitted with one click. The electronic equipment connects to the work point, surveying and mapping work surface, and mileage of the uploaded surveying and mapping data, automatically classifies and calculates statistics, automatically outputs relevant reports and core data, summarizes the loss coefficient and rebound coefficient, etc. for the next cycle control, and the system accumulates experience values ​​and combines them with the current excavation surface to accurately calculate the planned material lifting volume for the next cycle.
