Description

Web-based real-time survey data management system {WEB-BASED REALTIME SURVEYING MANAGING SYSTEM}

The present invention relates to a web-based real-time survey data management system, and more particularly, to transmit the survey data from the survey terminal to the central control server to perform storage and management functions, and to transmit the survey data to the application platform in real time. The present invention relates to a survey data management system that completes a drawing but detects data errors and automatically searches for and provides reference data for surveying to provide a more convenient, systematic and reasonable survey process.

Surveying is an essential process that must be investigated in advance for construction and civil engineering, and there are various surveying methods depending on the type and purpose.

These surveys are usually performed in a remote, multi-organizational relationship, usually in the past, where the survey office prepares the basics and delivers the basic data to the survey manager, who then conducts a field survey to the survey office. It was designed to convey or require the necessary data.

However, according to this method, surveying personnel who are divided into a number of people or groups according to each surveying purpose can not only check the progress of the survey in real time, but also can not obtain the missing reference data on the fly. In many cases, they visited their offices and made requests, and when they wanted to carry out a subsequent project in addition to the current project, they often lost time due to ambiguous work order and management systems. The environment could not be modified.

In order to prevent this problem, various solutions for collecting and managing survey data using web-based or wired / wireless communication methods are published.

The survey method using the Korean Patent No. 438003 real-time survey system is a method for inspecting the suitability between the attribute table structure and the code definition structure by searching the database for attribute table and survey item code definition file corresponding to the survey facility from the database. 1 course; A second step of determining whether the table is a point facility table or a linear facility table using an attribute table and a code definition file if there is no abnormality by checking the suitability and displaying the table; A third step of executing a prestored survey software and connecting to a land surveying equipment or a GPS receiver to determine and receive a survey state of survey data; A fourth step of searching for necessary information in surveying data received from the land surveying equipment or GPS receiver and classifying it into information such as location information (X, Y, Z coordinate), azimuth, vertical angle, survey date and time of the surveying facility; A fifth step of additionally inputting attribute information related to the type, content, and material of a survey item into survey figure data by rotating a display direction of a numerical drawing among the survey data or executing an attribute information input window; And a sixth process of dividing the survey figure data based on a survey date and storing the data in a database. It is posted that the effect of inputting attribute information according to the defined attribute input table and code can pursue the systematic management of survey data.

However, the above technique is faithful to the role of transmitting or adding survey data unilaterally, but it does not have a means for correcting or pointing out errors, and at the same time, it does not provide reference data for surveying, thereby adding convenience to surveyors. There is not enough.

The drawing creation module 310 performs a function of automatically creating an AutoCad-based drawing, in particular, a digital topographical drawing, based on the received survey data, for example, a line (string) in survey data generated when surveying a road. The role of connecting the road through the connection of the attribute data consisting of a pole and the attribute data displayed as a point, such as a pole, can automatically perform the method of estimating the position of the adjacent poles according to the distance of the poles to create a drawing.

In addition, the drawing creation module 310 transmits the drawing made up to now to the central control server 200 to be stored and stored in the central control server 200 and to the survey terminal 100 even though the drawing is not necessarily completed. By providing a property that allows a surveying worker carrying the survey terminal 100 to quickly check the drawings created to date.

The layer conversion module 320 provides a function of collectively converting survey data having various forms into NGIS standard layers (eg, an electronic design guide and delivery guideline, based on the Ministry of Land, Transport and Maritime Affairs), that is, if the survey data is different from each other. In case of having a format, it performs a function to uniformly change the format to one standard.

The error correction request module 330 extracts the survey data and the survey data that are determined to be obvious errors or conflict with the survey data when creating a drawing or converting layers through the survey data through the above function. It performs a function of performing a re-measurement request to the survey terminal 100 that generated the survey data with errors via the control server 200.

That is, for example, when the first, second, third, and fourth attribute data are connected to the line segment when the road is created, when the second attribute data has absolutely wrong coordinates or unfamiliar attributes, the data may be easily created when the drawing is created. Since it is an error judgment, the survey terminal 100 measuring the second attribute data (which can identify the source of the specific survey data by the identifiers assigned to the survey data through the identifiers of the survey terminals) can request the survey again. It provides the ability to collect modified data quickly.

As described above, the basic function of the application platform 300 may provide a function for applying the survey data in a manner such as drawing creation, layer conversion, error data grasp, and correction request.
