Description

Technical Field

[0001] The present invention relates to the technical field of geographic surveying and mapping methods, and in particular to an engineering surveying and mapping method suitable for cloud-based intelligent pre-arrangement. Background Art

[0002] Traditional transmission line design has a large workload and high work intensity in the field, and relies heavily on paper materials and on-site notes. Modern information technology is not widely used. During the construction drawing tower ranking stage, it is often necessary to conduct on-site surveys and positioning during the day, and to conduct internal work and finalize the drawings at night. If it is found that the line at a certain tower position needs to be modified during the evening finalization, the staff can only record the situation and then wait until the next day to re-survey and re-locate the location that needs to be modified. This will take a lot of time from problem discovery to problem handling, which greatly reduces the work efficiency of the entire process, so it needs to be technically upgraded. Summary of the Invention

[0003] The purpose of the present invention is to provide an engineering surveying and mapping method suitable for cloud-based intelligent pre-arrangement to solve the technical problems raised in the above-mentioned background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an engineering surveying and mapping method suitable for cloud-based intelligent pre-arrangement, comprising the following steps:

[0005] First, designers collect data on the locations that need to be surveyed through personal PC terminals. The personal PC terminals collect, load, and display the basic geographic information data used in transmission line design: image data, elevation data, thematic map data, and engineering survey data.

[0006] Secondly, in the second step, the designer imports the data collected in step S1 into the path statistical analysis module. The path statistical analysis module is an execution program installed in a personal PC terminal. During operation, the designer opens the path statistical analysis software through the portable personal PC terminal in step S1, and then modifies the path plan in real time on site to achieve the most ideal state for the selection of each pile position.

[0007] Next, in the third step, the designer uses the path statistics analysis module in step S2 to adjust the transmission line plan and direction. After the adjustment in step S2 is completed, the designer uses the personal PC terminal in step S1 to connect to the cloud intelligent server of the cloud PC terminal. The designer uses the server to start the cloud intelligent pre-scheduling and plan verification, and then guides the on-site personnel to make appropriate positioning.

[0008] Finally, in the fourth step, after the operations in steps S1, S2 and S3 are completed, the designer transmits the information back to the central database through the interactive module.

[0009] Preferably, the personal PC terminal includes a storage module, a multi-data loading module and an image data display module, and the storage module, the multi-data loading module and the image data display module are sequentially arranged and installed inside the personal PC terminal.

[0010] Preferably, the path statistical analysis module includes a path adjustment module, an information plotting module and a calculation module. The path statistical analysis module is composed of a combination of three functional aspects: the path adjustment module, the information plotting module and the calculation module.

[0011] Preferably, the cloud-based intelligent pre-scheduling and scheme verification module includes a cloud-based intelligent pre-scheduling module and a cross-span distance calculation module. The cloud-based intelligent pre-scheduling and scheme verification module completes the intelligent pre-scheduling and tower position adjustment scheme through the cloud-based intelligent pre-scheduling module. The cross-span distance calculation module assists design and survey personnel to quickly adjust the tower position and tower usage on site according to the results of calculation verification.

[0012] Preferably, the interaction module includes an information data extraction module, a line path data interaction module, a design result return module and an exploration data return module. The interaction module is constructed by combining the information data extraction module, the line path data interaction module, the design result return module and the exploration data return module.

[0013] Preferably, the information data extraction module is basic geographic information data. The information data extraction module is the part with the largest amount of data in the transmission line design work. The information data extraction module is equipped with an independent storage space for data storage.

[0014] Preferably, the line path data interaction module forms the final path design results according to the field survey situation, and realizes the sharing and interaction of path data between the mobile terminal and the PC terminal by establishing a standard line path interaction data package.

[0015] Preferably, the exploration data return module includes the device's own camera, microphone, data acquisition equipment and exploration data collection equipment. The exploration data return module binds the location attributes of these data using the GPS positioning function of the mobile terminal itself when collecting them.

[0016] Preferably, the calculation module is used by the design and survey personnel to perform relevant data calculation and statistical functions through the automatic calculation function of the mobile terminal device after adjusting the line path.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This engineering surveying method for cloud-based intelligent pre-scheduling allows designers to bring their personal PC terminals to the geographical location where the transmission line needs to be designed. Designers can then use portable mobile devices to modify the path plan in real time on-site, ensuring that each pile position is optimally selected. A cloud-based PC server then generates an intelligent pre-scheduling and tower position adjustment plan based on the intelligent design module to guide on-site personnel in proper positioning. Survey data, such as line selection data and elevation (DEM) data, are uploaded to the cloud-based PC server to generate a plan view. Based on this, intelligent pre-scheduling and tower position adjustment functions are performed. Office staff can perform preliminary ranking designs based on the path adjustment results, while field staff adjust and optimize pile positions based on the rankings. Finally, an interactive module transmits information back and forth, and upon returning to the office work environment, relevant data needs to be transmitted back to the PC for unified storage and management. This operating mode significantly reduces the need for path changes caused by unreasonable pile position settings, avoiding the waste caused by designers repeatedly visiting the site for surveys.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-3 The present invention provides a technical solution: an engineering surveying and mapping method suitable for cloud-based intelligent pre-arrangement, comprising the following steps:

[0024] First, designers collect data on the locations that need to be surveyed through personal PC terminals. The personal PC terminals collect, load, and display the basic geographic information data used in transmission line design: image data, elevation data, thematic map data, and engineering survey data.

[0025] Secondly, in the second step, the designer imports the data collected in step S1 into the path statistical analysis module. The path statistical analysis module is an execution program installed in a personal PC terminal. During operation, the designer opens the path statistical analysis software through the portable personal PC terminal in step S1, and then modifies the path plan in real time on site to achieve the most ideal state for the selection of each pile position.

[0026] Next, in the third step, the designer uses the path statistics analysis module in step S2 to adjust the transmission line plan and direction. After the adjustment in step S2 is completed, the designer uses the personal PC terminal in step S1 to connect to the cloud intelligent server of the cloud PC terminal. The designer uses the server to start the cloud intelligent pre-scheduling and plan verification, and then guides the on-site personnel to make appropriate positioning.

[0027] Finally, in the fourth step, after the operations in steps S1, S2 and S3 are completed, the designer transmits the information back to the central database through the interactive module.

[0028] The personal PC terminal includes a storage module, a multi-data loading module and an image data display module. The storage module, the multi-data loading module and the image data display module are sequentially arranged and installed inside the personal PC terminal. The storage module adopts multi-resolution pyramid storage, high-speed cache and GPU-assisted calculation. The multi-resolution pyramid uses a series of grids to represent the terrain of the same area. Adjacent grids use an even interval difference (usually an even number) to simulate terrains of different precisions through this "layering strategy". When displaying large-scale terrain, under certain conditions, using low-precision data instead of original data can greatly shorten data access time and improve display speed. In order to further improve data access time, a "quadtree block strategy" is used on each layer of grid to evenly divide a grid unit into four sub-units, and each sub-unit can be divided into four smaller parts. In this way, data read and write operations only need to access one tile unit, thereby greatly reducing the number of hard disk accesses and improving access efficiency.

[0029] The path statistical analysis module includes a path adjustment module, an information mapping module, and a calculation module. The path statistical analysis module is composed of the three functional aspects of the path adjustment module, the information mapping module, and the calculation module. The main task of the path adjustment module is to adjust and optimize the pile position. Design and survey personnel use mobile devices to quickly adjust the pile position based on the actual terrain conditions and the status of the crossing objects on site. Related design work includes: moving pile positions, adding pile positions, and deleting pile positions. Due to the use of smart mobile devices, the adjusted pile positions can be repositioned using the built-in GPS positioning module. The use of images and elevation data in the mobile device can provide various distance measurement functions when adjusting the pile position. When designing and surveying personnel for the information mapping module, they will take photos and videos of key areas (such as crossing objects and the terrain near the pile positions) during on-site inspections. In the past, it was usually necessary to carry special cameras to take pictures and manually upload them to a PC for annotation. After using smart mobile devices, the built-in camera function of the mobile device can be used to record and collect on-site photos and videos. At the same time, because smart mobile devices generally have GPS modules, photos collected on site can be automatically marked directly, greatly reducing the workload of manual editing. Relevant data can be stored on the mobile device and transmitted back to the PC. On the PC, it can be queried and retrieved according to the project route, and the corresponding geographical location can be browsed, making it easier to understand the on-site situation during office work.

[0030] The cloud-based intelligent pre-scheduling and scheme verification module includes a cloud-based intelligent pre-scheduling module and a cross-span distance calculation module. The cloud-based intelligent pre-scheduling and scheme verification module completes the intelligent pre-scheduling and tower position adjustment scheme through the cloud-based intelligent pre-scheduling module; the cross-span distance calculation module assists design and survey personnel in quickly adjusting the tower position and tower usage on site based on the calculation and verification results. In the transmission line cross-section diagram, the catenary formula is used to calculate the sag of the conductor and obtain the conductor sag diagram. Distance measurement and other means can be used to quickly verify whether the distance between the conductor and the ground and the cross-span meets the safety design requirements;

[0031] The interactive module includes an information data extraction module, a line path data interaction module, a design result return module, and an exploration data return module. The interactive module is constructed by combining the information data extraction module, the line path data interaction module, the design result return module, and the exploration data return module.

[0032] The basic geographic information data of the information data extraction module is the largest part of the data volume in the transmission line design work, and the information data extraction module is equipped with an independent storage space for data storage;

[0033] The route data interaction module forms the final route design results based on the field survey situation, and realizes the sharing and interaction of route data between the mobile terminal and the PC terminal by establishing a standard route interaction data package;

[0034] The exploration data return module includes the device's own camera, microphone, data acquisition equipment and exploration data collection equipment. The exploration data return module binds the location attributes of these data using the GPS positioning function of the mobile terminal itself when collecting them.

[0035] The calculation module allows designers and surveyors to automatically calculate and collect relevant data after making adjustments to the route. After adjusting the pile positions, the calculation module can immediately calculate the number of corner piles, the number of piles at tower locations, and the route's tortuosity coefficient, generating statistical reports. If the corridor data for this section includes thematic maps, it can also calculate intersections, crossings, contaminated areas, and other data closely related to engineering design. This real-time data provides accurate support and a basis for designers and surveyors to adjust the route.

[0036] In summary: Figure 1-3 As shown in the figure, when using this engineering surveying and mapping method suitable for cloud-based intelligent pre-scheduling, first, the designer takes a personal PC terminal to the geographical location where the transmission line needs to be designed. Then, the designer can use the portable mobile terminal device to modify the path plan in real time on site to achieve the most ideal state for the selection of each pile position. Then, the cloud PC server forms an intelligent pre-scheduling and tower position adjustment plan based on the intelligent design module to guide the on-site personnel to reasonably locate. The line selection data and elevation (DEM) data and other survey data are uploaded to the cloud PC server through the mobile terminal to generate a horizontal cross-section diagram. On this basis, the pole tower intelligent pre-scheduling and tower position adjustment functions are performed. The office staff can make a preliminary ranking design based on the path adjustment results, and the field staff adjust and optimize the pile positions according to the ranking situation. Finally, the interactive module transmits information back and forth. When returning to the office work environment, the relevant data needs to be transmitted back to the PC for unified storage and management. The above operation mode greatly reduces the path change work caused by unreasonable pile position setting and avoids the waste caused by designers repeatedly visiting the site for survey. This is the characteristic of the engineering surveying and mapping method suitable for cloud-based intelligent pre-scheduling.

[0037] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
