Description

Mobile Geographical Information Input System and Method

The present invention relates to a mobile geographic information input system and a method thereof, and more particularly, it is revised in real time by the earthwork plan by passing the earthwork site geographic information to the server and analyzing it on the server and sharing it to the entire workplace. The present invention relates to a mobile geographic information input system and method that can identify revised earthwork plans and changed geographic information regardless of time and place.

In the conventional earthwork site management system, the site manager confirms various situations occurring at the site on the day of occurrence. Report the confirmed situation in the field office in Excel or Word. Such a site management system is a method of post-checking and counting the site situation. There is a one-day time difference between the situation and the alternative. In addition, although the information on the occurrence situation is stored as digital information, the situation that does not take advantage of the digital information that is easy to move and share.

Prior Art Documents Korean Patent Registration Nos. 10-1546708 and 10-1669029 disclose techniques such as earthworks measurement methods or digital map generation based on earthworks measurement data. The reason for creating earthworks digital map is to establish an efficient construction management plan using digital map.

In order to establish the earthwork plan, it is necessary to compare the actual topography with the plan drawings to calculate the amount of earthwork (filling amount and cutting amount) according to the location. Based on the calculated soil volume information, the operation plan of the equipment should be prepared. At this time, geographic information including ground information and terrain information is required.

Geotechnical information means the classification of soil and cancer. The amount of cut and fill is changed according to the relevant ground information. Therefore, the equipment operation plan may be changed or revised.

The topographical information means the surface shape of the earthworks site. Based on the terrain information, when constructing a construction plan, the movement route of construction equipment (excavator, dozer, wheel loader, truck) can be suggested, and the efficiency of the equipment can be improved under the machine guidance system. Based on information such as soil quality, slope and wetness of the construction site, the movement route can be suggested.

In addition, the earthworks site is a region where large and large equipment is installed, and the work area of each equipment is an area where movement is limited or risks exist. In addition, there are spaces in which workers and equipment on which various materials and subsidiary materials of equipment are loaded cannot move. Such hazardous or restricted areas should also be excluded from the movement of personnel and equipment.

Meanwhile, the recent earthwork equipment is semi-automated in operation, and excellent guidance systems are actively developed. In addition, the proliferation of high-performance personal mobile devices, including smart phones, has expanded, and most of the economically active adults have at least one mobile device.

However, at earthworks sites, few site managers still manually organize and enter geographic information for the site. Therefore, all workers can collect geographic information on site using mobile devices, and can update construction plan information including plan drawings based on shared system updated in real time and geographic information collected in real time. Development of input systems and methods is required.

First Example  action

Hereinafter, with reference to the accompanying drawings will be described in detail the operation of the preferred embodiment.

4 is a flowchart illustrating a method of operating a mobile geographic information input system according to an embodiment of the present invention.

First, the field agent 10 inputs the ground information 111 including the classification of soil and cancer into the input unit 110 provided in the mobile device 100 (S01). The ground information 111 may be input as standardized character information, or may be input as unstructured image information using the image obtaining unit 112. The ground information 111 inputted as the atypical image information may be reconstructed as standardized information by being identified online by another field agent 10 or another ground expert in the earthworks site.

In addition, when the ground information 111 is input, context information 113 of a corresponding region may be input together. The contextual information 113 may also be generated and input as image information using the standardized text information and the image acquisition unit 112.

The sensor unit 120 provided in the mobile device 100 generates the terrain information 120-1 (S02).

The terrain information 120-1 is shape information of the terrain including the location information 121-1 of the point where the ground information 111 and the situation information 113 are input. The ground information 111 and the situation information 113 should be matched with the location information of the point where the information is generated, that is, the location where the information is located. The location information 121-1 may be generated using the GPS sensor 121.

The location information 121-1 using the GPS sensor 121 provides two-dimensional information. However, in the earthworks site, the contents of each work such as cutting and fill work may be different depending on the work area. Therefore, the ground information 111 and the situation information 113 of the earthworks site should be matched with the three-dimensional location information.

The sensor unit 120 of the mobile device 100 may further include the altimeter 122 and the direction-posture sensor 123 to generate the 3D terrain information 120-1. The altimeter 122 may generate the altitude information 122-1 using a barometric pressure measurement method.

The geographic information 130-1 stored in the construction information and construction plan information 211 stored in the construction information-storing unit 210 is always kept up to date (S05).

The geographic information 130-1 generated by the mobile device 100 is generated by a plurality of field agents 10 at their respective work locations and transmitted to the server 200. The transmitted geographic information 130-1 is stored in the geographic information storage unit 220 of the server. The stored geographic information 130-1 may be changed / modified by new geographic information 130-1 transmitted by another field agent 10.

In addition, the construction plan information 211 may be input in advance by a specific manager in charge of the construction plan including the site manager. The construction plan information may include planning drawings or cut works, schedules for filling work, and information on expected movement routes of the earthworks. Construction plan information 211 may be established based on the ground information predicted before the start of earthworks. If the ground information 111 differs from the predicted ground information or the progress schedule is changed in the course of earthworks, the construction plan information may be changed / revised.

The terminal-control unit 160 receives the latest geographic information 130-1 and the construction plan information 211 from the server communication unit 230 and displays it on the display unit 150 (S06).

At this time, the mobile device 100 may receive the changed / revised construction plan information 211.

That is, the geographic information 130-1 of a specific point input through the field agent 10 or the mobile device 100 is collected by the server 200. The collected geographic information 130-1 is reproduced as three-dimensional geographic information for each location of the entire earthworks site. Based on the three-dimensional ground information of the entire earthwork site re-created in this way, the construction plan information 211 established initially is changed / revised to maintain the latest state. The on-site agent 10 can receive the construction plan information 211 changed / revised in this way, it is possible to immediately check the changes associated with his work.

In addition, each field agent 10 can not check the ground information 111 and the situation information 113 at different work points of the earthworks site. However, the field agent 10 can receive and confirm the three-dimensional geographic information for each location of the entire earthworks site collected from the server. The three-dimensional geographic information for each location of the earthworks site may be generated as a digital map as digitalized map information.
