Description

Technical Field

[0001] The invention relates to the technical field of highway surveying, and in particular to a method and system for quickly digitizing and collecting field survey data for highway surveying. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Highway survey and design field investigation is the on-site investigation and measurement work carried out in the early stage of highway construction projects in order to obtain the field data such as topography, geology, hydrology, and transportation required for highway construction. Its purpose is to provide accurate and reliable basic data for highway design and ensure the feasibility and safety of highway construction. It generally includes multiple field investigation categories such as bridge and culvert investigation, route investigation, and demolition investigation. At present, the current status of the field is mostly recorded in paper records supplemented by taking photos, which cannot achieve rapid data collection.

[0004] For example, in the investigation of bridges, culverts and crossing projects, there are problems such as slow filling of survey forms, low efficiency in drawing river section diagrams / crossing road section diagrams and topographic and geological plane diagrams, and difficulty in timely viewing of longitudinal section design lines and longitudinal section ground lines within the specified mileage before and after the survey point.

[0005] For example, in tree compensation surveys, there are problems such as the inability to quickly and accurately obtain tree area and the difficulty in quickly and effectively counting the number of trees;

[0006] For example, in the investigation of special road sections, there is a problem that the scope of disposal of special road sections such as ponds and ditches is difficult to conveniently map and digitally record;

[0007] For example, in the survey of demolition of power, telecommunications and pipeline facilities, there is a problem that the pile numbers and offsets of the demolition range are difficult to quickly calculate and record.

[0008] In summary, the data collection efficiency of field investigations in highway survey and design is low and the degree of digitization is low. Summary of the invention

[0009] In order to solve the above problems, the present invention proposes a method and system for rapid digital acquisition of highway survey field investigation data, so as to realize rapid acquisition of highway survey field investigation data.

[0010] To achieve the above object, the present invention adopts the following technical solutions:

[0011] First, a method for rapid digital collection of highway survey field survey data is proposed, comprising the following steps:

[0012] Get the map scene, select the corresponding type of data survey form according to the survey point collection instructions;

[0013] Select the survey point location in the map scene, determine the survey point stake number, and add it to the corresponding data survey table;

[0014] Select the survey item in the data survey table, add the corresponding data to the data survey table, and display the survey point number and survey type information associated with the data survey table in the map scene;

[0015] Among them, the corresponding data is added to the data survey form, specifically:

[0016] For the survey field information that can be pre-acquired through the Weidi design parameter control file stored in the database, including but not limited to the project name, center pile number, span, span angle, etc., it is directly added to the corresponding data survey table;

[0017] For the survey field information that is not applicable to pre-acquisition through the Weidi design parameter control file, the actual survey data, the graphic data generated based on the actual survey data, and the map scene screenshots required for the survey items and the annotation information corresponding to the screenshots are added to the data survey form according to the survey items in the data survey form.

[0018] Furthermore, the survey items include river cross-section diagrams and intersecting road cross-section diagrams. According to the horizontal distance and elevation difference actually obtained, the corresponding cross-section diagrams and the attribute annotations of each line segment in the cross-section diagrams are generated and filled into the corresponding survey forms.

[0019] Furthermore, the survey items also include topographic and geological plan diagrams. By calling up the map scene and rotating it to a set orientation, and selecting a screenshot range, a screenshot of the required map scene is taken, and the screenshot is used as a topographic and geological plan diagram. Attribute information is annotated in the image and filled into the corresponding survey form.

[0020] Furthermore, the survey items also include the number of trees. The number of trees can be obtained directly through survey, or by calling up a map scene and drawing the tree range in the map scene. Based on the equal-area projection area calculation method, the number of trees of different types and corresponding diameter ranges can be obtained according to the horizontal spacing, vertical spacing and proportion of the trees, and filled in the corresponding survey form.

[0021] Furthermore, the survey items also include the scope of special road section treatment. By calling the map scene, the scope of the special road section and / or the scope of treatment of the special road section is drawn in the map scene, and the drawn scope is used as survey data and filled into the corresponding survey form.

[0022] Furthermore, the survey items also include the stake numbers and offsets of the starting and ending points of the demolition range of power, telecommunications and pipeline facilities. By calling up the map scene, the power, telecommunications and pipeline facilities in the map scene that need to be demolished due to highway construction are determined, and the coordinates of the demolition starting and ending points are obtained. Using the identification code of the current survey route, the stake numbers and offsets of the starting and ending points are automatically calculated through the latitude and longitude data files stored in the database, and filled in the corresponding survey form.

[0023] Furthermore, a prefabrication survey form for bridge and culvert intersection structures is generated according to the Weidi design parameter control file and some basic information is obtained, including the following steps:

[0024] According to the identification code corresponding to the current survey route, the associated bridge and culvert intersection structure information is obtained according to the Weidi design parameter control file, and the type of the bridge and culvert intersection structure prefabrication survey form to be added is determined according to the project type, structure information category and the keywords of the project name in the structure information;

[0025] According to the identification code, query the latitude and longitude project file to determine whether there is a chain break. If there is no chain break, the center pile number in the structure information is the real pile number. The longitude and latitude coordinates of the survey point corresponding to the prefabricated survey form are calculated according to the identification code and the center pile number of the structure information. If there is a chain break, the center pile number in the structure information is the broken chain pile number. The longitude and latitude coordinates of the survey point corresponding to the prefabricated survey form are calculated according to the identification code and the broken chain pile number.

[0026] Fill in the structural information associated with the survey form and the corresponding longitude and latitude coordinates of the survey points into the survey form of the corresponding type.

[0027] Furthermore, the survey items also include longitudinal section design lines and longitudinal section ground line displays, using the database to determine the identification code of the survey route corresponding to the survey point pile number, and querying the latitude and land project file based on the identification code to determine whether there is a broken link;

[0028] If there is no broken link, the survey point pile number is the real pile number. According to the real pile number and the set mileage length, the survey point design elevation, the survey point ground elevation, the real pile number of the ground line point, the ground line point design elevation and the ground line point ground elevation are determined based on the latitude and longitude data file stored in the database, and the longitudinal section design line, the longitudinal section ground line and the line segment intersecting the longitudinal section ground line and the longitudinal section design line are generated; the corresponding data and the generated drawings are added to the data survey table;

[0029] If there is a broken chain, the survey point pile number is the broken chain pile number. According to the broken chain pile number and the mileage length set before and after the survey point, the survey point design elevation, survey point ground elevation, ground line point broken chain pile number, ground line point design elevation and ground line point ground elevation are determined based on the latitude and longitude data file stored in the database, and the longitudinal section design line, longitudinal section ground line and the line segment intersecting the longitudinal section ground line and the longitudinal section design line are generated; the corresponding data and generated drawings are added to the data survey table.

[0030] Secondly, a fast digital acquisition system for highway survey field survey data is proposed, including:

[0031] The questionnaire generating unit is configured to: obtain a map scene, and select a corresponding type of data questionnaire according to a survey point collection instruction;

[0032] The survey data filling unit is configured to: select the survey point location in the map scene, determine the survey point stake number, and add it to the corresponding data survey table;

[0033] The survey data filling unit is further configured to: select survey items in the data survey table, add corresponding data to the data survey table, and display survey point pile numbers and survey type information associated with the data survey table in the map scene;

[0034] Among them, the corresponding data is added to the data survey form, specifically:

[0035] For the survey field information that can be pre-acquired through the Weidi design parameter control file stored in the database, including but not limited to the project name, center pile number, span, span angle, etc., it is directly added to the corresponding data survey table;

[0036] For the survey field information that is not applicable to pre-acquisition through the Weidi design parameter control file, the actual survey data, the graphic data generated based on the actual survey data, and the map scene screenshots required for the survey items and the annotation information corresponding to the screenshots are added to the data survey form according to the survey items in the data survey form.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] 1. Data preservation during the highway survey field investigation is realized in a digital way. When conducting the highway survey field investigation, the corresponding data survey form is called according to the obtained survey instructions. According to the survey items in the survey form, the preset survey field information data (such as the project name, center pile number, span, etc. of the bridge and culvert structure) is selected from the database and filled into the survey form. The missing data in the survey items are filled through actual survey activities. During the actual survey activities, according to the requirements of different survey items, the actual survey data, the graphic data generated according to the survey data, or the image data captured in the map scene and the corresponding annotation data are filled into the survey form. By filling in the survey form digitally, the efficiency of field investigators in collecting survey data is improved.

[0039] 2. By using the digital fast drawing method, the river section diagram and the intersecting road section diagram can be quickly drawn in the investigation of bridges, culverts and crossing projects by entering the horizontal distance, elevation difference and attributes, which improves the drawing efficiency and the degree of digitization.

[0040] 3. By taking screenshots and editing the map scenes, the rapid drawing of topographic and geological plan diagrams in bridge, culvert and intersection engineering surveys is achieved, saving drawing time.

[0041] 4. Through the rapid drawing and display method of longitudinal section design line and longitudinal section ground line, the rapid calculation of the height difference between the design line and the ground line at the survey point of bridges, culverts and intersection projects and the dynamic drawing of the longitudinal section design line and longitudinal section ground line within the specified mileage before and after the survey point are realized, which is convenient for field survey personnel to quickly and accurately determine the span, upper structure type, lower structure type, foundation type, maximum excavation depth of the intersecting road and other contents of the structure at the current survey point.

[0042] 5. By drawing the range of trees in the map scene and combining it with the equal-area projection area calculation method, the number of trees can be quickly counted.

[0043] Advantages of additional aspects of the present invention will be given in part in the following description, and in part will become obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] In the absence of conflict, the embodiments of the present invention and the features of the embodiments may be combined with each other.

[0057] Example 1

[0058] like Figure 1 As shown, a method for rapid digital collection of field survey data for highway surveying includes the following steps:

[0059] Get the map scene, select the corresponding type of data survey form according to the survey point collection instructions;

[0060] Select the survey point location in the map scene, determine the survey point stake number, and add it to the corresponding data survey table;

[0061] Select the survey item in the data survey table, add the corresponding data to the data survey table, and display the survey point number and survey type information associated with the data survey table in the map scene;

[0062] Among them, the corresponding data is added to the data survey form, specifically:

[0063] When the data to be added is the survey field information data pre-existing in the database, the database is used to determine the identification code of the survey route corresponding to the survey point pile number, the preset survey field information data related to the survey route is determined according to the identification code, the coordinates of the survey point in the survey route are determined, and the obtained coordinates together with the preset survey field information data are added to the data survey table;

[0064] When the data to be added is not the survey field information data pre-existing in the database, the actual survey data, the graphic data generated based on the actual survey data, and the map scene screenshots required for the survey items and the annotation information corresponding to the screenshots are added to the data survey table according to the survey items in the data survey table.

[0065] In this embodiment, the survey field information that can be pre-acquired through the latitude and longitude design parameter control file stored in the database, including but not limited to the project name, center pile number, span, span angle, etc., is directly added to the corresponding data survey table.

[0066] For the survey field information that is not applicable to pre-acquisition through the Weidi design parameter control file, the actual survey data, the graphic data generated based on the actual survey data, and the map scene screenshots required for the survey items and the annotation information corresponding to the screenshots are added to the data survey form according to the survey items in the data survey form.

[0067] The map scene contains multiple types of map data, and also contains highway design data. The above data is called layer data. During the field investigation of highway survey, different layer data are retrieved and displayed in the map scene according to different survey point collection instructions.

[0068] By obtaining the survey point pile number corresponding to the location of the collection terminal, the corresponding data survey table can be selected according to the survey point collection instruction, and the survey point pile number can be added to the data survey table for display. The collection terminal is a hardware platform that supports the operation of the method of this embodiment and has the function of obtaining location information, for example, it can be a tablet computer.

[0069] When the pile number obtained according to the positioning information of the acquisition terminal does not meet the requirements, you can change the pile number by clicking the survey point pile number change button in the data survey table and selecting the survey point in the map scene;

[0070] When you need to input survey data, you can enter the survey data of the survey point into the data survey form through the survey data input box in the data survey form; after the data survey form is saved, it will be displayed in the map scene with the survey point stake number and survey item (survey type information) as the name.

[0071] The basic data required for the field investigation of highway surveys include the layer data required for the field investigation and the basic data related to the field investigation route; among them, the layer data include image maps, highway overall route design maps, highway maps and highway topographic maps; the basic data related to the field investigation route are latitude and land data files, including project files (*.prj), plane curve data files (*.pm), longitudinal section design data files (*.zdm), longitudinal section ground line data files (*.dmx) and design parameter control files (*.ctr). Basic data are data related to survey and design. Through basic data, the preset survey field information data of bridges, culverts and intersection engineering structures can be obtained, including but not limited to the center pile number, project name, span and span angle, etc.

[0072] Combination Figure 2-Figure 8 , a method for rapid digital collection of highway survey field investigation data disclosed in this embodiment is described in detail.

[0073] In the specific implementation, it is allowed to modify the survey point stake number, specifically: call and display the map scene, select the survey point in the map scene to obtain the latitude and longitude coordinates of the selected survey point, or obtain the latitude and longitude coordinates of the survey point through real-time positioning of the acquisition terminal, and finally calculate the stake number of the survey point through the program, and add the stake number of the survey point to the data survey table.

[0074] The survey point collection instructions of this embodiment include but are not limited to bridge, culvert and intersection project collection instructions, tree compensation collection instructions, special road section collection instructions and demolition power, telecommunications and pipeline facilities collection instructions; among them, the bridge, culvert and intersection project collection instructions include bridge and culvert survey form collection instructions, intersection project survey form collection instructions, bridge and intersection project reconstruction and expansion survey form collection instructions and culvert reconstruction and expansion survey form collection instructions.

[0075] The types of data survey forms corresponding to the survey point collection instructions include but are not limited to the following:

[0076] The data survey form selected according to the bridge and culvert survey form collection instruction is the bridge and culvert survey form;

[0077] The data questionnaire screened according to the cross-engineering questionnaire collection instructions is the cross-engineering questionnaire;

[0078] The data survey form selected according to the survey form collection instruction for reconstruction and expansion of bridge crossing projects is the survey form for reconstruction and expansion of bridge crossing projects;

[0079] The data survey form selected according to the collection instruction of survey form for reconstruction and expansion of culverts is the survey form for reconstruction and expansion of culverts;

[0080] The data survey form selected according to the tree compensation collection instructions is the tree compensation data survey form;

[0081] The data survey form selected according to the special road section collection instruction is the special road section data survey form;

[0082] The data survey form selected according to the demolition power, telecommunications and pipeline facility collection instructions is the demolition power, telecommunications and pipeline facility data survey form.

[0083] Among them, the survey items in the bridge and culvert survey form, the intersection survey form, the reconstruction and expansion bridge intersection survey form and the reconstruction and expansion culvert survey form include the center pile number, project name, span and span angle, etc.;

[0084] For the above four data survey tables, the survey field information data preset in the database is first retrieved. When the preset survey field information data cannot meet the needs of the current survey item, the data obtained from the actual survey is filled into the survey table. For example, by retrieving the map scene, a point is selected in the displayed map scene, and the pile number of the selected point is filled into the corresponding survey table as the center pile number; by retrieving the project name selection interface, the corresponding project name is selected and filled into the survey table; by retrieving the span selection interface, the corresponding span is selected and filled into the survey table; the span angle is input and filled into the survey table. At the same time, the survey table generates corresponding drawings, patterns or lines based on the input data and fills them into the survey table.

[0085] The survey items of the bridge and culvert survey form, intersection project survey form, bridge intersection project survey form and culvert reconstruction and expansion survey form include river section diagrams and intersecting road section diagrams. By calling the section diagram data input interface, inputting the horizontal distance, elevation difference and attributes, the corresponding section diagram is generated in the drawing interface according to the horizontal distance and elevation difference, and the attributes of each line segment in the section diagram are annotated; the section diagram annotated with attributes is filled into the survey form.

[0086] The survey items of the bridge and culvert survey form, intersection project survey form, bridge and intersection project reconstruction and expansion survey form, and culvert reconstruction and expansion survey form also include topographic and geological plan diagrams. By calling up the diagram input interface, starting the screenshot function, calling up the map scene, and rotating the map scene to the set orientation, the required map scene can be screenshoted by selecting the screenshot range, and the screenshot can be used as a topographic and geological plan diagram and filled into the survey form.

[0087] The survey items in the tree compensation data survey form include tree species, tree quantity, tree range, tree diameter, horizontal spacing, vertical spacing and ratio; fill the tree species, tree diameter, horizontal spacing, vertical spacing and ratio into the tree compensation data survey form; by calling and displaying the map scene, drawing or selecting the tree range in the map scene, and filling the obtained tree range into the tree compensation data survey form to automatically calculate the number of trees; when the number of trees can be directly obtained on site, the number of trees can be directly filled into the survey form.

[0088] The survey items in the special road section data survey form include the special road section treatment scope. The special road section treatment scope is drawn by calling and displaying the map scene and clicking or moving the sampling points in the map scene. The obtained special road section treatment scope is filled into the special road section survey form.

[0089] The survey items in the survey form for demolished power, telecommunications and pipeline facilities data include the starting and ending pile numbers and offsets of the demolished facilities. The longitude and latitude coordinates of the starting and ending points of the demolished facilities are obtained by selecting points in the map scene or by equipment positioning. Then, the pile numbers and offsets of the starting and ending points of the demolished facilities are determined based on the latitude and longitude data files stored in the database, and filled in the survey form for demolished power, telecommunications and pipeline facilities.

[0090] There are four types of prefabrication survey forms for bridge and culvert intersection structures, namely: bridge and culvert survey form, intersection project survey form, reconstruction and expansion bridge intersection project survey form and reconstruction and expansion culvert survey form. If the project type is a new construction project, the types of prefabrication survey forms for bridge and culvert intersection structures include bridge and culvert survey form and intersection project survey form; if the project type is a reconstruction and expansion project, the types of prefabrication survey forms for bridge and culvert intersection structures include bridge and culvert survey form, intersection project survey form, reconstruction and expansion bridge intersection project survey form and reconstruction and expansion culvert survey form.

[0091] Specifically, generating a prefabrication survey form for bridge and culvert intersection structures according to the design parameter control file stored in the database includes the following steps:

[0092] According to the identification code corresponding to the current survey route, the structural information associated with the survey route is obtained according to the latitude and longitude design parameter control file stored in the database. The structural information includes two categories: bridge and culvert crossing structural information and culvert structural information. The specific content of the structural information includes the project name, center pile number, span, span angle, etc.

[0093] Determine the type of prefabrication survey form for bridge and culvert crossing structures to be added based on the project type, structure information category and keyword information in the project name;

[0094] According to the identification code, query the latitude and longitude project file to determine whether there is a chain break. If there is no chain break, the center pile number in the structure information is the real pile number. The longitude and latitude coordinates of the survey point corresponding to the prefabricated survey form are calculated according to the identification code and the center pile number of the structure information. If there is a chain break, the center pile number in the structure information is the broken chain pile number. The longitude and latitude coordinates of the survey point corresponding to the prefabricated survey form are calculated according to the identification code and the center pile number of the structure information.

[0095] Fill the structural information associated with the survey form and the latitude and longitude coordinates of the corresponding survey points into the survey form of the corresponding type.

[0096] If the project type corresponding to the current survey route is a new project, and the acquired structure information is bridge and culvert intersection structure information, and the keyword extracted from the project name in the bridge and culvert intersection structure information contains "separated interchange", the type of the bridge and culvert intersection structure prefabrication survey form is determined to be an intersection project survey form, and the bridge and culvert intersection structure information is pre-filled into the intersection project survey form; otherwise, the bridge and culvert intersection structure information is pre-filled into the bridge and culvert survey form.

[0097] If the project type corresponding to the current survey route is a new project, and the acquired structure information is culvert structure information, and the keyword extracted from the project name in the culvert structure information contains "overpass", it is determined that the type of the prefabrication survey form for bridge and culvert intersection structures is a cross-project survey form; the culvert structure information is pre-filled into the cross-project survey form, otherwise, the structure information is pre-filled into the bridge and culvert survey form.

[0098] If the project type corresponding to the current survey route is a reconstruction and expansion project, and the acquired structure information is bridge and culvert intersection structure information, and the keywords extracted from the project name in the bridge and culvert intersection structure information contain "new construction" and "separated interchange" but not "demolition and new construction", the type of the bridge and culvert intersection structure prefabrication survey form is determined to be an intersection project survey form, and the bridge and culvert intersection structure information is pre-filled into the intersection project survey form; when the keywords extracted from the project name in the bridge and culvert intersection structure information contain "new construction" but not "demolition and new construction" and "separated interchange", the type of the bridge and culvert intersection structure prefabrication survey form is determined to be a bridge and culvert survey form, and the bridge and culvert intersection structure information is pre-filled into the bridge and culvert survey form. If none of the above is met, the bridge and culvert intersection structure information is pre-filled into the reconstruction and expansion bridge intersection project survey form.

[0099] If the project type of the survey point is a renovation and expansion project, and the structure information obtained is culvert structure information, and the keywords extracted from the project name in the culvert structure information contain "new construction" and "overpass", but do not contain "demolition and new construction" and "reinforcement and utilization", the type of the prefabrication survey form for bridge and culvert intersection structures is determined to be a cross-project survey form, and the culvert structure information is pre-filled into the cross-project survey form; if the keywords extracted from the project name in the culvert structure information contain "new construction", but do not contain "overpass", "demolition and new construction" and "reinforcement and utilization", the prefabrication survey form type for bridge and culvert intersection structures is determined to be a cross-project survey form, and the culvert structure information is pre-filled into the cross-project survey form; ", determine the type of the prefabricated survey form for bridge-culvert intersection structures to be the bridge-culvert survey form, and pre-fill the bridge-culvert survey form with the culvert structure information; when the keyword extracted from the project name in the culvert structure information contains "overpass" and contains "demolition and new construction" or "reinforcement and utilization", determine the type of the prefabricated survey form for bridge-culvert intersection structures to be the reconstruction and expansion bridge intersection project survey form, and pre-fill the culvert structure information into the reconstruction and expansion bridge intersection project survey form; if none of the above is met, fill the culvert structure information into the reconstruction and expansion culvert survey form.

[0100] After determining the structural information of the survey route and the longitude and latitude coordinates of the survey points, the survey points are loaded and displayed in the map scene according to the type of prefabricated survey form for bridge, culvert and intersection structures, the structural information and the longitude and latitude coordinates of the survey points; the structural information is filled into the corresponding type of prefabricated survey form for bridge, culvert and intersection structures according to the project type corresponding to the survey route, the structural information category and the project name in the structural information, thereby eliminating the process of field investigators adding survey points and filling in structural information such as project name, center pile number, span, span angle, etc. at the field site, thereby improving the speed of filling in the content of the bridge, culvert and intersection project survey form.

[0101] like Figure 2As shown in the figure, during the investigation of bridges, culverts and intersections, after the ctr structure adding function is turned on, the ctr bridge, culvert and intersection structure database table and the ctr culvert structure database table are queried to obtain the structure information associated with the investigation route, including two categories of bridge, culvert and intersection structure information and culvert structure information. The specific content includes project name, center pile number, span and span angle. Then, according to the keywords in the project type, structure information category and project name field filled in when the project was created, it is determined which type of investigation form each structure information should be pre-filled into. Then, the latitude project file database table is queried, and the latitude project file associated with the investigation route is used to determine whether the route has a broken link. After that, according to the broken link judgment result, the corresponding method is selected to calculate and determine the longitude and latitude coordinates of the investigation point, and each structure information and the corresponding investigation form type and longitude and latitude coordinates of the investigation point are obtained. According to the longitude and latitude coordinates of the investigation point, the prefabricated investigation point loading method is called to load and display the investigation point in the map scene, and the investigation form automatic filling method is called to fill the structure information into the corresponding investigation form.

[0102] like Figure 3 As shown in the figure, during the investigation of bridges, culverts and crossing projects, in order to facilitate the field investigators to draw graphics, the field investigators can draw the river section diagram and the intersecting road section diagram by directly inputting the horizontal distance, height difference and attributes. Specifically, according to the acquisition instruction of the bridge and culvert survey form, after calling and displaying the bridge and culvert survey form, click the river section diagram or the intersecting road section diagram drawing button to call the section diagram data input interface; enter the horizontal distance, height difference and attributes in the section diagram data input interface; every time a set of horizontal distance and height difference is entered, a line segment will be drawn in the drawing interface according to the horizontal distance and height difference; and the length, height difference and attributes of the line segment will be displayed.

[0103] Preferably, the length of the line segment is displayed above the line segment. When the height difference is a negative value, the height difference is displayed on the left side of the line segment. When the height difference is a positive value, the height difference is displayed on the right side of the line segment. The actual meaning of each line segment can be marked through the attributes, such as cement road, dirt road, river ditch, etc. When the preset input box in the cross-section data input interface cannot meet the drawing requirements, a row of input boxes can be added through the add line function. When there is a problem with the drawn graphics, it can be undone through the undo function, or erased through the erase function. The entire row of input boxes and their filled contents can be deleted through the delete line function, and the graphics can be scaled through the zoom in and zoom out functions.

[0104] like Figure 4As shown, during the investigation of bridges, culverts and intersections, the topographic and geological plane diagram at the investigation point can be obtained by screenshot. Specifically, according to the acquisition instruction of the bridge, culvert and intersection survey form, after calling and displaying the bridge, culvert and intersection survey form, click the screenshot button of the topographic and geological plane diagram, call the map scene, and locate the survey point, automatically calculate the angle between the forward direction of the survey route to which the survey point belongs and the due north of the map scene, and rotate the map scene and the route design overall diagram according to the angle, so that the forward direction of the route turns to the due north of the map scene, and then select the screenshot range, and take a screenshot of the rotated map scene according to the selected screenshot range. After taking the screenshot, enter the screenshot editing interface, in which you can add the intersection angle, the type of the road being crossed, etc. to the screenshot, so as to complete the quick screenshot and editing of the topographic and geological plane diagram, and fill the screenshot as the topographic and geological plane diagram into the bridge, culvert and intersection survey form.

[0105] like Figure 5 As shown, during the investigation of bridges, culverts and crossing projects, after the longitudinal section design line and longitudinal section ground line drawing functions are turned on, the longitudinal section design line and longitudinal section ground line are drawn and displayed according to the pile number and design elevation required for drawing the longitudinal section design line, the pile number and ground elevation required for drawing the longitudinal section ground line, the design elevation of the survey point and the ground elevation of the survey point, and the design elevation, ground elevation and fill and cut height of the survey point are displayed.

[0106] Specifically, set the display buttons of the longitudinal section design line and the longitudinal section ground line in the data survey table. By clicking the display buttons of the longitudinal section design line and the longitudinal section ground line, the longitudinal section design line, the longitudinal section ground line and the vertical line intersecting the longitudinal section ground line and the longitudinal section design line at the survey point are generated and displayed. The identification code corresponding to the current survey route, the survey point stake number, the mileage length before and after the survey point to be drawn, and the horizontal and vertical scaling ratio are used as query parameters. First, query the latitude and land project file according to the identification code to determine whether there is a broken link:

[0107] If there is no broken link, the survey point pile number is the real pile number. According to the real pile number of the survey point and the set mileage length, the real pile number of the ground line point within the set mileage length before and after the survey point is queried from the longitudinal section ground line data;

[0108] According to the real stake number of the ground line point within the set mileage before and after the survey point, the ground elevation of the ground line point within the set mileage before and after the survey point is queried from the longitudinal section ground line data file, and the ground elevation of the obtained ground line point is processed by the linear interpolation method to obtain the ground elevation of the survey point;

[0109] According to the real stake number of the survey point and the real stake number of the ground line points within the set mileage before and after the survey point, the design elevation at the survey point and the design elevation at the ground line points are calculated through the longitudinal section design line data file;

[0110] Return the design elevation of the survey point, the ground elevation of the survey point, the real stake number of the ground line point, the design elevation of the ground line point and the ground elevation of the ground line point;

[0111] The design elevations of the ground line points are connected according to the order of the real pile numbers of the ground line points to obtain the longitudinal section design line; the ground elevations of the ground line points are connected according to the order of the real pile numbers of the ground line points to obtain the longitudinal section ground line; taking the real pile number position of the survey point on the horizontal coordinate axis as the starting point, a vertical ray is generated along the vertical coordinate axis direction, and the vertical ray intersects with the longitudinal section ground line and the longitudinal section design line to form a vertical line intersecting with the longitudinal section ground line and the longitudinal section design line.

[0112] The fill and cut height of the survey point is obtained by subtracting the ground elevation of the survey point from the design elevation of the survey point. The survey point pile number, design elevation, ground elevation and fill and cut height are displayed on the drawing page.

[0113] If there is a broken chain, the survey point pile number is the broken chain pile number. At this time, you need to convert the broken chain pile number of the survey point to the real pile number of the survey point.

[0114] According to the real stake number of the survey point and the set mileage length, the real stake number of the ground line point within the set mileage length before and after the survey point is queried from the longitudinal section ground line data;

[0115] According to the real stake number of the ground line point within the set mileage before and after the survey point, the ground elevation of the ground line point within the set mileage before and after the survey point is queried from the longitudinal section ground line data file, and the ground elevation of the obtained ground line point is processed by the linear interpolation method to obtain the ground elevation of the survey point;

[0116] According to the real stake number of the survey point and the real stake number of the ground line points within the set mileage before and after the survey point, the design elevation at the survey point and the design elevation at the ground line points are calculated according to the longitudinal section design line data file;

[0117] Convert the real stake number of the ground line point within the set mileage before and after the survey point into the broken chain stake number of the ground line point; return the design elevation of the survey point, the ground elevation of the survey point, the broken chain stake number of the ground line point, the design elevation of the ground line point and the ground elevation of the ground line point;

[0118] The design elevations of the ground line points are connected in the order of the broken chain pile numbers of the ground line points to obtain the longitudinal section design line; the ground elevations of the ground line points are connected in the order of the broken chain pile numbers of the ground line points to obtain the longitudinal section ground line; taking the broken chain pile number position of the survey point on the horizontal coordinate axis as the starting point, a vertical ray is drawn along the vertical coordinate axis direction, and the vertical ray intersects with the longitudinal section ground line and the longitudinal section design line, and is a vertical line intersecting with the longitudinal section ground line and the longitudinal section design line.

[0119] The fill and cut height of the survey point is obtained by subtracting the ground elevation of the survey point from the design elevation of the survey point. The broken chain pile number, design elevation, ground elevation and fill and cut height of the survey point are displayed on the drawing page.

[0120] Field survey personnel can not only conveniently check the fill and excavation height at the current survey point and learn the height difference between the design elevation and the ground elevation at the survey point, but also quickly check the longitudinal design line and the longitudinal ground line within the set mileage before and after the survey point, which is convenient for field survey personnel to quickly and accurately determine the span of the structure at the current survey point, the superstructure type, the substructure type, the foundation type, the maximum excavation depth of the intersecting road, and other contents.

[0121] like Figure 6 As shown, during the tree compensation investigation, if the number of trees in the corresponding diameter range of a certain type of trees can be directly counted, the actual number counted will be added to the corresponding data investigation table; if it cannot be directly counted, the tree range will be drawn in the map scene, and the tree area corresponding to the tree range will be calculated. The number of trees of different types and diameter ranges will be calculated based on the tree area, horizontal spacing, vertical spacing and ratio, and the results will be added to the corresponding data investigation table.

[0122] During the tree compensation investigation process, field investigators select or fill in the tree types in the tree compensation investigation form based on the actual conditions on site. If the number of trees in the corresponding diameter range of a certain type of tree can be directly counted, the actual number counted will be added to the investigation form. If it cannot be directly counted, the number of trees will be calculated by obtaining the tree range in the map scene.

[0123] Before obtaining the tree range, open the online image and topographic map layer in the map scene. According to the actual conditions of the trees in the field, the field investigators can obtain the tree range by drawing the tree range in the map scene. Calculating the number of trees by tree range is to calculate the number of trees by the tree area corresponding to the tree range, as well as the tree type, tree diameter, horizontal spacing, vertical spacing, and proportion. In order to obtain the accurate tree area, the equal area projection method is used to calculate the area of ​​the obtained tree range.

[0124] During the tree compensation survey, the number of trees is calculated according to the tree type and different diameter ranges. At present, the tree types are divided into large tree categories and small tree categories, and the diameter range is divided into four types: less than 6cm, 6-10cm, 11-20cm, and greater than 20cm. Four input boxes are set for the survey of trees of different types and different diameter ranges: horizontal spacing (m), vertical spacing (m), proportion (%), and number (trees). During the survey, if the number of trees of each tree type and the corresponding diameter range can be counted on site, the number of trees can be directly filled in; if the number of trees of each tree type and the corresponding diameter range cannot be counted on site, the tree range can be drawn in the map scene to automatically calculate the total area of ​​the tree range, and then the number of trees of each tree type and the corresponding diameter range is automatically calculated according to the filled-in tree type, tree diameter, horizontal spacing, vertical spacing and proportion (the proportion refers to the percentage of trees of different types and different diameter ranges in the total area of ​​the tree range), thereby generating a tree compensation survey form. The calculation formula for the number of trees within the corresponding diameter range of each tree type is: number of trees = tree area / horizontal spacing / vertical spacing*(proportion / 100).

[0125] Through the above steps, the range of different types of trees can be quickly obtained, the tree area can be accurately calculated, and the number of trees of different types and diameters can be quickly and automatically counted.

[0126] During the investigation of special sections, investigators will determine from online images or on-site conditions which ditch or pond is occupied by the designed route based on the conditions of the online images and the overall route design drawings, and then use the occupied area as the special section disposal area and draw it on the map scene.

[0127] like Figure 7 As shown in the figure, taking "pond" as the special road section treatment range drawing as an example, before drawing the special road section treatment range, open the online image, route design overall map and other layers in the map scene. According to the actual situation on site, the pond special road section treatment range is drawn in the map scene in combination with the online image and route design overall map. When drawing, you can add the pond special road section treatment range coordinate points by clicking in the map scene, or you can add the pond special road section treatment range coordinate points by collecting the coordinate points by the location of the mobile terminal device on site. The range coordinate points added by the two methods will be connected and drawn into lines in sequence and displayed in the map scene. The field investigators can see the drawn content in time. After the drawing is completed, the first range coordinate point and the last range coordinate point are automatically connected to form a closed surface. During the drawing process, you can cancel, drag, clear and other operations on the range coordinate points, which is convenient for editing and modifying the drawn content. The geographical location of the special road section treatment range coordinate points added during the drawing process is digitally recorded and saved in the form of longitude and latitude coordinates.

[0128] like Figure 8 As shown, during the survey of the demolished power, telecommunications and pipeline facilities, taking a section of poles and wires to be demolished as an example, the longitude and latitude coordinates of the starting and ending points of the poles and wires to be demolished can be obtained through the terminal equipment positioning method, or the starting and ending positions of the poles and wires to be demolished can be found in the map scene and the longitude and latitude coordinates of the starting and ending points of the poles and wires to be demolished can be obtained by clicking. After the longitude and latitude coordinates of the starting and ending points of the poles and wires to be demolished are obtained, the currently used survey route identification code and the obtained longitude and latitude coordinates are used as query parameters, and the stake number and offset of the starting and ending points of the poles and wires to be demolished are automatically calculated based on the basic data stored in the database, and the stake number and offset are automatically filled in the survey form for the demolished power, telecommunications and pipeline facilities.

[0129] In the investigation of bridges, culverts and intersections, the method of quickly generating prefabricated investigation forms for bridge, culvert and intersection structures through design parameter control files solves the problems of slow filling in of investigation forms and difficulty in quickly finding the investigation location in the investigation of bridges, culverts and intersections, and improves the efficiency of filling in investigation forms.

[0130] In the investigation of bridges, culverts and crossing projects, digital rapid drawing methods are used to quickly draw river section diagrams and intersecting road section diagrams by entering horizontal distances, elevation differences and attributes, thereby improving drawing efficiency and the degree of digitization.

[0131] In the investigation of bridges, culverts and intersection projects, by screenshotting and editing the map scene with online images and route design general drawings, the rapid drawing of topographic and geological plan diagrams was achieved, saving drawing time.

[0132] In the investigation of bridges, culverts and intersections, the rapid drawing and display method of longitudinal section design lines and longitudinal section ground lines enables the rapid calculation of the height difference between the design elevation and the ground elevation at the investigation point of bridges, culverts and intersections, as well as the dynamic drawing of longitudinal section design lines and longitudinal section ground lines within a specified mileage before and after the investigation point. This facilitates field investigators to quickly and accurately determine the span of the structure at the current investigation point, the type of superstructure, the type of substructure, the type of foundation, the maximum excavation depth of the intersecting road, and other contents.

[0133] In the tree compensation survey, the tree range is quickly obtained by drawing the tree range in the map scene; the tree area is accurately calculated by using the equal-area projection area calculation method; and the number of trees of different types and diameters is quickly counted by using the fast and automatic tree counting method.

[0134] In the investigation of special road sections, the treatment range of special road sections such as ponds and ditches is drawn by clicking and moving sampling points in the map scene, which realizes the rapid drawing of the treatment range of special road sections and the digital recording of geographic coordinates.

[0135] In the survey of demolished power, telecommunications and pipeline facilities, the longitude and latitude coordinates of the starting and ending points of the demolished section are quickly acquired through two methods: obtaining coordinates by positioning the terminal device and obtaining coordinates by clicking in the map scene. The pile number and offset calculation method is used to automatically calculate the pile number and offset of the starting and ending points of the demolished section.

[0144] Data preservation during highway survey field investigation is realized in a digital way. When conducting highway survey field investigation, the corresponding data survey form is called according to the obtained survey instructions. According to the survey items in the survey form, the preset survey field information data (such as the project name, center pile number, span, etc. of the bridge and culvert structure) is selected from the database and filled into the survey form.
