The present invention relates to a positioning data acquisition system and method.

GPS (Global Positioning System) is a state-of-the-art satellite positioning system that provides accurate time information while providing the ability to grasp the three-dimensional position of the ground in real time.

Because GPS measurement can achieve higher accuracy and efficiency than existing surveying techniques, most of the basic surveying is done by using GPS, and the utilization rate is also increasing rapidly in public surveys and construction surveys. GPS positioning applications such as civil engineering / construction, archeology, transportation, leisure, navigation, as well as surveying applications are expanding widely.

However, GPS measurement requires a measuring device capable of precise coordinate calculation. Since such a device generally has a tripod and a main body together, it is difficult to carry and it is necessary to interlock with an additional device for accurate coordinate calculation. There is a problem that a lot of manpower is consumed.

Here, the operation display module may include: a display unit for outputting the position information generated by the position information generation module on a screen; And an operation unit having a switch for controlling generation of log data of the control module.

On the other hand, the positioning data collection system of the present invention comprises: one or more GPS satellites for transmitting position data; A virtual reference station server for generating correction data according to position data of the GPS satellite through GPS data collected from a plurality of GPS constant observation stations and a DGPS (Differential GPS) reference station; A communication terminal communicating with the virtual reference station server and receiving correction data; And a positioning data collecting device for measuring a heading azimuth angle and receiving position data and correction data from the communication terminal and the GPS satellite and generating position information through the measured azimuth angle, position data and correction data, The positioning data collection device can correct the position data received from the GPS satellite in real time through the correction data received from the communication terminal and generate position information including the corrected position data and the measured azimuth angle.

here, The virtual reference station server receives location data through the communication terminal, and analyzes the GPS data of the GPS constant observation station and the DGPS base station to generate correction data according to the location data.

On the other hand, the positioning data collecting method of the present invention is characterized in that: (a) the position information generating module receives position data from GPS satellites and transmits the correction data generated by the virtual reference station server for correcting the position data from the communication terminal Receiving; b) the position information generation module measures a heading azimuth angle, and generates position information through the heading azimuth, position data and correction data received by the communication module and the position information generation module; And c) generating log data according to the location information generated in the location information generation module by the control module.

Here, the receiving unit 122 may be provided in the form of a GPS antenna that receives a signal of the GPS satellite 200, and may be located at an upper portion of the frame 160 to minimize the reception rate of position data.

The azimuth measuring unit 124 may measure the heading direction of the positioning data collecting apparatus 100, that is, the moving direction when the vehicle is loaded on a person or a moving object.

The azimuth measurement unit 124 calculates the moving speed and the position to generate a resultant value. By receiving the correction data through the communication terminal 400 in a situation where the reception of the GPS satellite 200 is slow or the mobile communication network is unavailable, In this difficult situation, the position data of the positioning data collecting apparatus 100 may be replaced or used as correction data.

Here, the azimuth measuring unit 124 may be a gyro sensor, an accelerometer sensor, or the like so as to measure the moving inertia and the direction of the positioning data collecting apparatus 100 through yaw, roll, A sensor integrated IMU (Inertial measurement unit) can be used, and a Kalman filter algorithm can be used to calculate the travel speed and position.

The information generating unit 126 may generate positional information based on the position data of the GPS satellite 200, the correction data of the communication terminal 400, and the heading azimuth measured by the azimuth measuring unit 124. [

The information generating unit 126 corrects the position data of the GPS satellite 200 using the correction data received from the communication terminal 400 and outputs the corrected position data and the heading azimuth angle of the positioning data collecting apparatus 100 And generates location information including the location information.

Therefore, the control unit 136 can generate and store new log data through the log generating unit 132 by generating a control signal in accordance with the operation of the operation unit 144. When generation and recording of log data are not necessary, It is possible to prevent the above-described log data from being generated.

[

Here, the operation display module 140 may be provided in the form of a remote controller connected to the position information generation module 120 and the control module 130, respectively.

The power supply module 150 may supply power to the communication module 110, the location information generation module 120, and the control module 130.

Here, the power supply module 150 may be provided with a corresponding switch 152 connected to the power supply module 150 so as to separately supply or cut off power to each module, The power of the corresponding module can be controlled to be turned on / off or reset.

The frame 160 may fix each module and the receiver 122.

Here, the frame 160 can indirectly protect the positioning data collecting apparatus 100 from an external impact, and even when a separate backpack (not shown) or a cover for collecting or storing positioning data during movement is used, It is possible to prevent the positioning data collecting apparatus 100 from malfunctioning or malfunctioning by directly contacting the backpack or the cover.
