Description

Total station of numerical map measuring ground feature with sea-level}

The present invention relates to a total station for geodetic surveying for level surveying. More specifically, geodetic surveying is performed by using coordinate information obtained by analyzing arithmetic averages of GPS signals received through a plurality of paths while directly moving the ground on which a feature is changed. The present invention relates to a total station for geodetic surveying for leveling, which improves the accuracy of coordinate information since the digital map is updated in real time.

Surveying or geodetic surveys are first performed for civil engineering, architectural design, and construction, and surveying determines the position between points by measuring the horizontal distance, elevation (level or level), and direction between one reference point and another adjacent reference point. It is common to refer to all activities that numerically indicate in the drawings.

A general level survey is a method of continuous surveying of levels from the ground reference point, which knows altitude or sea level, through the midpoint to the target point.

Leveling is to read the scales of staff (staffs, bars or scales) installed at the front and rear of the leveling instrument.The scales of the staffs installed at the rear reference point of the leveling instrument are read first, and then the scales of the staffs installed at the front target point. This method is used to measure the level of both points by calculating the difference between the readings of each reading and repeating this process to the final target point.

The staff installed at the front point in one of the level surveys are used as the rear point staff in the next step through the change of direction.

The staff who was installed at the forward point shall turn or rotate the scaled surface in the opposite direction so that the leveling instrument which has moved to the position of the next procedure may read the scale of the staff.

An operator is needed to repeat the process of installing and surveying the leveling device and staff continuously moving to the starting, intermediate and target points of the leveling survey.

Even when the level where the level of the indicator is to be measured is an area where the level of worker safety cannot be secured, the level of the indicator needs to be precisely measured.

As a level measurement by the prior art, there is a "level measurement method" according to Patent Registration No. 10-0648462 (Nov. 15, 2006).

1 is a conceptual diagram for explaining a leveling method according to an embodiment of the prior art.

Hereinafter, with reference to the accompanying drawings in detail the staff is installed at the point K by the worker and the leveling device is installed at the point I1 by the worker.

The leveling device at point I1 records the staff at point K as a backsight, moves the staff to point P1, records the survey as a display, and then moves to point I2.

The leveling device at point I2 records the staff at point P1 as a backsight, moves the staff to point P2, records the survey as a display, and then moves to point I3 until the level at point H is surveyed. .

The leveling method according to the prior art has the advantage of accurately measuring the level of the indicator, but the worker handling the leveling device and the staff must move directly from the reference point of the area where the level is to be surveyed to the target point.

The GPS signal received by the GPS receiver 840 in real time is supplied to the latitude analysis module 850, the longitude analysis module 860, the sea level analysis module 870, and the time analysis module 880, respectively.

The GPS receiver 840 removes noise and amplifies to a predetermined level when receiving the GPS signals broadcast by at least three GPS satellites 1100, and analyzes them with values of latitude, longitude, elevation, and time. The signal can be output in real time.

The latitude analysis module 850 analyzes the GPS signal input from the connected GPS receiver 840 and calculates and outputs latitude information of a place where the staff probot 1200 is currently located.

Real-time output of average latitude values with more than three times the accuracy.

The latitude value arithmetic operation performed by the arithmetic mean arithmetic unit 940 is as follows.

(1st latitude value + 2nd latitude value + 3rd latitude value) / 3 = Arithmetic mean computed latitude value

Equation is calculated by the corresponding algorithm, it is natural that the algorithm can be changed if the equation is changed, the following arithmetic mean calculation algorithm is applied in a similar manner will not be described again.

The hardness value averaging unit 950 analyzes each of the first to third hardness analysis modules 860 and receives the first to third hardness values of a place where the staff robot 1200 is currently located, and performs an arithmetic mean calculation process. The average hardness value with more than three times the accuracy is output in real time.

The arithmetic mean calculating unit 960 is analyzed from the first to third elevation analysis modules 870, respectively, and receives arithmetic mean calculations in real time by receiving all the first to third elevation values of the place where the staff robot 1200 is currently located. By processing, the average level above sea level is raised in real time.

The time value averaging unit 970 analyzes each of the first to third time analysis modules 880 and receives arithmetic averages of all of the first to third time values at the place where the staff robot 1200 is currently located. Arithmetic processing outputs an average time value of 3 times higher accuracy in real time.

Therefore, the GPS unit 1211 wirelessly receives the GPS signals through three paths, respectively, calculates and outputs coordinate information, and outputs an average coordinate value of three times higher accuracy by performing an arithmetic mean operation on the three coordinate information.

The survey control unit 1212 monitors and controls the overall functions of the staff robot 1200, and includes a GPS unit 1211, a storage unit 1213, a communication unit 1214, and first to fourth motor units 1221, 1222, and 1223. , And may be connected to the driving motor block 1220 for monitoring and control, and may control a camera unit not shown in the figure to capture a video image of the site.

The survey controller 1212 may operate by data stored in a storage unit and a program or downloaded data and a command signal received from the program or the total station server 1500.

A vertical forming unit 1232 formed of the supporting unit 1238; And
The plurality of support parts 1238 are fixedly installed on both sides of the central part, respectively, and the first to fourth motor parts 1221, 1222, 1223, and 1224 are fixed by using the fixing band 1225 and the fixing bolt 1226. It is made to include a frame portion 1239 fixed to each of the corners of the place and generally have a rectangular flat plate shape,
The GPS unit 1211 is connected to the first to third GPS antennas 810, 820, and 830, respectively, to receive a GPS signal from the GPS satellite 1100, and analyzed by latitude, longitude, elevation, and time. First to third GPS module units 910, 920, and 930 for outputting coordinate information of the first to third GPS modules;
A latitude value averaging unit 940 for inputting a latitude value analyzed from at least one selected from the first to third GPS module units 910, 920, and 930 and performing arithmetic mean calculation to output the latitude value;
A hardness value average calculation unit 950 for inputting a value of hardness analyzed from at least one selected from the first to third GPS module units 910, 920, and 930, and performing an arithmetic average calculation to output the hardness value;
A sea level value arithmetic unit 960 for inputting a value of the sea level analyzed from at least one selected from the first to third GPS module units 910, 920, and 930 and performing an arithmetic mean calculation to output the arithmetic mean; And
A time value average calculation unit 970 for inputting a value of time analyzed from at least one selected from the first to third GPS module units 910, 920, and 930, and performing an arithmetic average operation to output the calculated values; Total station for geodetic survey for leveling consisting of.
