The displacement amounts of the X, Y, and Z axes of the structures 5 graphicized by the first to third graphic units 33 to 35 are provided to the Internet accessor through the image information output unit 36. The structure diagnosis information (displacement graph) as described above is provided to the visitor through the Internet under the control of the controller 37 when the visitor accesses the diagnosis information providing apparatus 3 through the Internet and requests the diagnosis information.

The accessor can connect to the control unit 37 of the diagnostic information providing apparatus 3 using a PC 6 capable of internet communication, and the control unit (7) using a wireless communication terminal 7 capable of wireless internet communication as another means. 37).

First, the reference coordinate setting device 1 is installed on land without a change in position as shown in FIG. 3, and the displacement coordinate measuring device 2 is installed on the structure 5 to be diagnosed. An example of the structure 5 is shown a large long bridge.

When the reference coordinate setting device 1 is installed on land as described above, and the displacement coordinate measuring device 2 is installed on the structure 5, the first receiver 12 of the reference coordinate setting device 1 is a satellite 4. The position information transmitted from the antenna is received through the satellite antenna 11, and the first X-axis, Y-axis, and Z-axis coordinate detectors 13 to 15 are X-axis, The reference coordinates for the Y and Z axes are detected, and the first wireless modem 16 wirelessly transmits the detected three-dimensional reference coordinates to the second wireless modem 29 of the displacement coordinate measuring apparatus 2.

At this time, the second X-axis, Y-axis, and Z-axis coordinate detection units 23 to 25 of the displacement coordinate measuring apparatus 2 are structure 5 as position information received from the satellite 4 through the second receiver 22. The structure 5 (long bridge) is detected in the up, down, left, and right directions when a strong wind blows or a vehicle, especially a vehicle with a large load, passes over the bridge. As shown in FIG. 5, the coordinates of the structure 5 detected by the second X, Y, and Z axis coordinate detectors 23 to 25 are shaken in the X, Y, and Z directions. To change.

On the other hand, the displacement coordinate calculation unit 26 of the displacement coordinate measuring device 2 is a reference coordinate for the X-axis, Y-axis, Z-axis supplied from the reference coordinate setting device 1 and the second coordinate detection unit (23 to 25) Comparing the coordinates for the structure (5) supplied from the to calculate the three-dimensional displacement of the structure (5), and transmits the result of the calculation to the diagnostic information providing apparatus (3) through the first communication module (27).

Herein, the operation of the displacement coordinate calculator 26 will be described. For example, assuming that the reference coordinate with respect to the Z axis is 5, the structure 5 provided by the second Z axis coordinate detector 25 according to a time change is described. ) Is 5.0, 5.2, 5.3, 4.9, 4.7, the Z-axis displacement of the structure 5 calculated by the displacement coordinate calculator 26 is calculated as 0, +0.2, +0.3, -0.1, -0.3 It is transmitted to the diagnostic information providing apparatus (3).

The displacement coordinate storage unit 32 of the diagnostic information providing apparatus 3 stores the displacement amount of the structure 5 transmitted from the displacement coordinate measuring apparatus 2 and input through the second communication module 31, The third to third graphics units 33 to 35 graph the displacements of the X, Y, and Z axes with respect to the structure 5 stored in the displacement coordinate storage unit 32 and supply them to the image information output unit 36. .

At this time, when a manager or other person who manages the structure 5 requests the diagnostic information about the structure 5 by connecting to the control unit 37 through the Internet, the control unit 37 outputs the image information output unit 36. To control the 3D displacement amount of the structure 5 graphed by the first to third graphic units 33 to 35 in real time to the accessor (manager or other person concerned) through the Internet.

At that time it is possible to determine the state of the structure (5) as well as to accurately determine whether or not the safety of the structure (5).

In addition, the present invention may not only provide a three-dimensional displacement graph for the structure 5 in real time through the Internet, but also may alert the safety of the structure 5 as a measured result.

That is, when the output value of the first to third graphic units 33 to 35 is monitored and the output value (displacement amount) is out of the preset tolerance range, a predetermined alarm signal is transmitted to the manager via the Internet to provide the structure (5). Is to warn you of safety.

However, this method has a measurable advantage in real time, but in this case, since it requires a large memory capacity to provide accurate resolution data, there is a problem that the system construction requires a lot of cost.

In other words, commercial GPS receivers track the carrier phase of satellites coming in through the GPS antenna, and the raw data received by the receiver alone cannot be accurately measured in a few or several centimeters. Displacement information of several to several centimeters can be obtained only by introducing a carrier-phase differential GPS method using the carrier phase of the mobile station's raw data. The capacity of the GPS raw data (mobile station) is about 24 megabytes per receiver when received in one health, the processing capacity is n * 24 megabytes per day when using n (n) receivers, the vibration displacement of the structure When data is received at 10 health or more in order to obtain information and precise GPS coordinates, the capacity is more than 10 times of 1 health and a large amount of communication equipment is required.

Therefore, the existing GPS structure displacement system method extracts the precision coordinates by processing the GPS or Altika (RTK) processing on the receiver, or by sending the coordinates of the reference station to the mobile station system using wireless communication. A communication device that accepts local PS coordinates and a computer capable of processing DGPS or RTK should be internal or external to the receiver, show only the coordinates of the mobile station, and use a wireless modem. There is a problem that is limited by the distance.

The present invention is intended to solve this problem, and an object of the present invention is to reduce the cost of system construction by eliminating the GPS measurement data in a post-processing manner rather than in real time, thereby reducing the cost of system construction and eliminating user access traffic. The purpose of this paper is to provide a method for extracting GPS displacement data using the Internet.

FIG. 11 is an enlarged graph of a portion of FIG. 10.

The present invention configured as described above receives the GPS raw data through the mobile station 40 and the reference station 50 as shown in FIG. 4 through the GPS receivers 42 and 52 so as to be connected to the Internet network through the Internet connection 43 and 53. do. The server 60 connects to the Internet connection unit 63 through the Internet network and recognizes the GS data through the mobile station 40 and the reference station 50 by the GS control unit 62.

The GPS control unit 62 performs the steps according to the flowchart of FIG. 7. Of course, the mobile station 40, the reference station 50, and the server 60 must designate an IP address to enable Internet access.

The server 60 processes the data of the mobile station 40 and the reference station 50 by the control action of the GPS control unit 62, and the processing is based on the data provided through the mobile station 40 and the reference station 50. It is checked by the GS control unit 62 via the IP whether it is a station or a mobile station (first step S1).

If it is determined that the data is the reference station, the GS control unit 62 divides the data into reference station data and stores them in the main storage medium 61 (S2-1). The reference station GCS precision coordinates are extracted (S2-2). The step (S2-2) of extracting the precise coordinates checks whether there is a request of the reference station PS raw data stored in the main storage medium 61 in the GS control unit 62 as shown in FIG. 8 (S2-21). If present, the precision post-processing operation of the GS data of the reference station 50 is performed (S2-22), and the network adjustment of the reference station PS data is performed according to the calculation (S2-23), and the reference station precision coordinates according to the network adjustment are calculated. Extracting and extracting to store in step S2-3 is performed (S2-24).

Subsequently to the step S2-2, the GS control unit 62 stores the reference station PS coordinates extracted value in the post-processing result storage medium 65 (S2-3). In synchronization with the mobile station, the corresponding reference station coordinates and raw data are extracted (S2-4), and the post-processing operation is performed in step S3-2.

The post-processing value in step S3-2 is stored in the post-processing result storage medium 65 in the mobile station GPS coordinates (S4). This stored value is extracted from the post-processing result storage medium of the mobile station and the reference station at the request of the user (S5-1), and then stored on the monitor 66 or the individual monitor of the user 71 in a desired form. To appear (S5-2).

The post-processing result is shown in FIG. 10 or 11 as shown in FIG. 10, and the computation process is performed to quantify the data so that the user can see it in a graphic form. You can exemplify what appears.

 In this case, for example, as shown in FIG. 10, the data of the mobile station 40 and the reference station 50 may be extracted at the same time so that a more accurate position change may be known. That is, in FIG. 11 in which FIG. 10 is enlarged, when the reference station 50 data is the displacement 1 (L1 + a) at the point of 25 seconds based on the reference displacement L1, the coordinate of the mobile station 40 is the displacement 2 (L1 + b), the displacement difference between the reference station and the mobile station can simply be determined by the displacement 3 (c). In other words, if the conventional method determines that the data of the reference station 50 is fixed and measures only the data of the mobile station, the conventional method determines that the displacement b has moved. Since the displacement (c) is extracted and the extracted precision coordinates are judged at regular intervals by the post-processing method, the mobile station and the reference station are coordinated and processed simultaneously while reducing the storage data, so that the absolute accurate displacement movement can be confirmed. .

In the present invention, when the control unit 62 determines that the data is a mobile station, the control unit 62 divides the data into mobile station data, stores the data in the main storage medium 61, and then sets the standard set by the control unit 62 (that is, the mobile station 40 and the reference station 50). This is because the standard for processing the data of the standard can be compared with each other when the standard is processed), but the data is collected by the time interval (for example, the average value of the moving data for 5 seconds), and the precision coordinates are extracted by the post-processing method (S2 -2), and stores in the post-processing result storage medium 65 and extracts the coordinates of the reference station at the user's request (S2-4).

Subsequently, the data extracted in the second step S2 is subjected to post-processing operation with the data through the mobile station (S3), so that the data value can be output to a separate post-processing result storage medium 65 as shown in FIG. 10 or 11. (4th step S4). Of course, the stored value may be stored in a file of a certain interval (monthly, weekly), or data may be linked to a file processed by a function so that different results may be flexibly displayed on the monitor 66 according to a user's function designation. .

Upon request of the user 71 to 7n, the server 60 uses its own content (for example, content that sets a display form according to the user's request when the server provides a main screen). The stored data of 65) is quickly recalled for loading (fifth step S5).

According to the present invention, when the mobile station 40 and the reference station 50 measure their respective data through a hub 45 and a 55 as shown in FIGS. 5 and 6, in this case, the data of each region in Bukhansan is measured. When configured to provide a more accurate data can be obtained. Meanwhile, as shown in FIG. 4, the mobile station 40 and the reference station 50 may be distributed and installed in this case (in this case, dispersed in Namsan, Bukhansan, Gwanaksan, etc.), which may provide more accurate GPS information of various regions. For example, the data for providing store only the result value in the post-processing result storage medium 65 so that the load traffic of the data due to the storage is reduced, so that a faster and more accurate service can be provided.

As described above, the present invention uses the method of providing the data of both the mobile station and the reference station to the server through the Internet network, so that the mobile station and the reference station do not need to store their own data. Since it does not require a storage medium, the installation cost of mobile station and reference station is reduced, so it can be installed in many places, so that more accurate information can be confirmed, thereby providing reliability.

In addition, the present invention is not a method of processing the data of the mobile station and the reference station in real time, but a data processing for a predetermined time by a post-processing method is stored separately in the post-processing result storage medium and provided to the user, to provide access and data It reduces the amount of traffic required to provide fast and accurate data.
