Field of technology

The present invention provides a surveying system mounted on a vehicle, comprising: a GPS antenna (110) for receiving a satellite signal, and a GPS having software for processing a signal received from the GPS antenna to calculate, display, and store position coordinates of a measurement point. The GPS instrument 100 including the receiver 120 is integrally combined with the total station 200 in which the pen computer software is built, which measures, displays, and stores the position coordinates of the measurement points by measuring angles and distances. It is about a surveying system.

Prior art

Conventional surveys are classified into GPS surveys for measuring position by satellite and total station surveys for measuring azimuth and distance (inclined distance, horizontal angle, and altitude angle) by laser observation using optics, as shown in FIG. 4. Each of these devices is separate.

First, a description of GPS is as follows.

GPS consists of 24 GPS satellites over 20,000km, which allows an unlimited number of users to observe 4 or more satellites from any location on Earth, so there is a 95% chance that civil users will have a plane error of about 20m (2drms). You can calculate your position in the range: distance root mean square). In order to calculate the location using GPS, four basic information is calculated from the three-dimensional position of the GPS receiver and the error of the GPS receiver clock which is much more inaccurate than the atomic clocks such as Cesium and Rubydium mounted on the GPS satellite. Since all four unknowns have to be solved, the location must be calculated based on data from at least four GPS satellites. Each of the 24 GPS satellites used in this manner transmits a unique PRN (Pseudo Random Noise) code and information (navigation messages) such as satellite position coordinates to the carrier. There are two carriers used in this manner, L1 and L2. The frequencies are 1.575 GHz and 1.227 GHz, respectively. Civilians are allowed to receive only L1, and the military can receive both L1 and L2.

A new survey method that has been introduced since the late 1990s in the field of GPS surveying is the real time kinematic GPS positioning method. It is a technique that can calculate the precise distance between two points immediately after observation by using wireless radio communication to transfer the necessary part of data from one observation receiver to the other receiver. The accuracy is low, but the advantage is that the position can be measured in a short time in real time.

The GPS survey can be performed only in open areas where there are no obstacles on the surface such as buildings and forests, so that total station surveys are performed in areas where GPS surveying is not possible. In this case, in order to use the GPS survey results for total station surveying, it is necessary to calculate and input machine point coordinates.

This is because the position coordinates calculated as a result of GPS survey are three-dimensional geodetic coordinates expressed in longitude, latitude, and height, and must be converted to the current national coordinate system expressed in azimuth and distance in order to be used for total station surveying. Therefore, the process of inputting the coordinate transformation and the converted coordinates to the total station should be involved, and in this process, a high possibility of error due to a mistake of the operator and a problem of deterioration of work efficiency occurs.

In addition, separate GPS equipment and total station equipment are each provided, and in general, three or more persons are required to operate these equipments.

The object of the present invention created to solve the above problems is as follows.

First, it is an object of the present invention to provide an integrated surveying system in which the GPS equipment and the total station equipment are organically combined and integrated.

Secondly, another object of the present invention is to provide an integrated surveying system equipped with a moving means.

Third, another object of the present invention is to provide an integrated survey system that can produce a survey map, such as a topographic map or cadastral map using the survey results.

Fourthly, another object of the present invention is to provide an integrated survey system equipped with a communication modem capable of transmitting a survey result or a manufactured topographic map to a third place.

Technical composition of the present invention created to achieve the above object is as follows.

The present invention provides a survey system mounted on a vehicle, comprising: a GPS antenna (110) for receiving a satellite signal; And a GPS receiver (100) having software for processing the signal received from the GPS antenna to calculate, display and store the position coordinates of the measuring point. A total station 200 having built-in software for a pen computer for measuring, measuring angles and distances, calculating, displaying and storing position coordinates of measurement points; An adapter 250 for integrally coupling the central axis of the GPS antenna 110 with the central axis of the total station 200; And, connected to the GPS instrument 100 and the total station 200 by wire or wireless data transmission and reception is possible, conversion of the coordinate values measured by the GPS instrument 100 and the total station 200 and Work computer 300 that can be edited; including, wherein the adapter 250 is integrally fixed to the central portion of the handle portion 210 provided on the top of the total station 200 main body is projected upwards and the thread is formed It is fastened to the female screw formed on the lower end of the GPS antenna 110.

In this way, after installing the adapter 250 and processing the female screw on the lower end of the GPS antenna 110, when the female screw of the GPS antenna 110 is fastened to the adapter 250, the center axis of the GPS antenna 110 and the total station automatically. This will match.

Therefore, the coordinate values measured using the GPS instrument 100 can be converted and used as a mechanical point (coordinate of the position where the total station is installed) of the total station 200.

In addition, the cut portion 33 is covered with a glass or acrylic sheet of transparent material.

The reason for cutting off part of the trailer loading box 22 is because the center axis of the total station 200 installed in the trailer can be matched with the reference point of the ground by using the radar pointer system. In other words, it is possible to easily perform the collimation work to match the mechanical point of the total station 200 to the reference point on the surface.

Therefore, in order to use the total coordinates indicated by the longitude, latitude and height calculated as a result of GPS surveying to the total station surveying, the coordinate conversion task of automatically converting the coordinates to the current national coordinate system indicated by azimuth and distance can be executed automatically. Coordinate conversion and input work are unnecessary.

In addition, there is an effect that can be verified by comparing the results of the GPS survey and the results of the total station survey.

Such coordinate transformation work may be performed in the work computer 300, the software for the coordinate transformation is built in the GPS receiver 120, the work computer 300 from the GPS instrument 100 to convert the coordinate values May be received.

Work computer 300 may be embedded with a CAD program capable of creating and editing a survey map, such as a topographic map or cadastral map, using the position coordinate data received by the GPS instrument 100 and the total station 200.

When such a CAD program is embedded, data about position coordinates can be secured, and survey maps such as topographic maps and cadastral maps can be created in the field.
