Referring to FIG. 1, the cadastral reference point monitoring system 100 includes a cadastral reference point 110, a cadastral reference point monitoring apparatus 120, and a cadastral reference point management server 130, which can be connected through a network.

The cadastral reference point 110 is a part of a cadastral reference point and measures the specific point according to surveying, waterway survey and measurement standards according to a specific law and displays it as coordinates in order to ensure accuracy of measurement and increase efficiency. Means the point used. The cadastral reference point 110 may provide a signal to the cadastral point monitoring apparatus 120 using Bluetooth low energy (BLE) communication with the antenna embedded in the bottom of the cover. In one embodiment, the cadastral reference point 110 may periodically transmit a beacon signal to the cadastral reference point monitoring device 120.

The cadastral reference point monitoring apparatus 120 corresponds to a portable computing apparatus that receives a signal of the cadastral reference point 110, and may be implemented, for example, as a smartphone or a notebook computer. In one embodiment, the cadastral reference point monitoring apparatus 120 can estimate the landing direction of the cadastral reference point 110 using the GPS signal and calculate the distance to the landing position of the cadastral reference point 110. [

2 is an exploded perspective view illustrating the structure of the cited reference point shown in Fig.

2, the cadastral reference point 110 includes a cover 210, a BLE beacon 220, a packaging nail 230a, an unpacking fixture 230b, and a body 240. As shown in FIG.

The cover 210 may be circularly coupled at the top of the cadastral reference point 110 to secure the BLE beacon 220. In one embodiment, the cover 210 may be detachable and releasable, which facilitates maintenance and management, such as battery replacement of the BLE beacon 220. In one embodiment, the cover 210 may couple the press antenna to its lower end to minimize the beacon signal that may be attenuated during the embedding process.

The BLE beacon 220 can be inserted inside the body 240 and includes a beacon cover 221, a PCB fixture 222, a BLE board 223 and a beacon case 224, . In one embodiment, the BLE board 223 may be coupled to a press antenna capable of transmitting a beacon signal to provide more precise location to the cadastral point monitoring device 120.

3 is a block diagram illustrating the cadastral reference point monitoring device 120 in FIG.

3, the cadastral reference point monitoring apparatus 120 includes a buried region guide unit 310, a beacon signal processing unit 320, a cadastral reference point distance calculation unit 330, a cadastral reference point abnormality notification unit 340, (350), a server communication unit (360), and a control unit (370).

The embedment area guide unit 310 detects the current position of the cadastral point monitoring apparatus 120 and guides the path to the cadastral landmark embedding area. The cadastral cadastral landing area may correspond to an area based on the position of the cadastral reference point 110, taking into account the signal error of the GPS (Global Positioning System). For example, As shown in FIG. The embedment area guide unit 310 can guide the surveyor or the manager from the current position estimated based on the GPS signal to the cadastral landmark embedding area.

In one embodiment, the embedment area guide unit 310 divides the screen of the cadastral reference point monitoring apparatus 120, arranges a map showing a route to a specific cadastral reference point 110 in a part thereof, And displays the captured image. For example, the embedment area guide unit 310 can arrange a map indicating the route to the cadastral reference point 110 at the top of the screen of the cadastral reference point monitoring apparatus 120, and arrange the capturing screen at the bottom of the screen. In one embodiment, the buried region guide portion 310 may overlay the visual guidance of the cadastral reference point 110 in a direction toward a particular cadastral reference point 110. For example, a visual guidance can be added as an arrow on the map screen, and clicking on the arrow shape can provide the remaining distance to the cadastral landmark embedding area.

The beacon signal processing unit 320 estimates the embedding direction of the cadastral reference point 110 using the GPS and searches for the BLE beacon 220 signal when entering the cadastral reference point embedment area. The beacon signal processing unit 320 may periodically receive the beacon signal from the BLE beacon 220 disposed in the curved depression area at the lower end of the cover 210 of the cadastral reference point 110 and may receive the beacon signal . In one embodiment, the beacon signal processing unit 320 may display the embedding direction of the cadastral reference point 110 estimated via GPS on a map and search for a predefined frequency region to detect the BLE beacon 220 signal. For example, when the beacon signal processing unit 320 approaches the specific cadastral reference point 110, the beacon signal processing unit 320 may detect the BLE beacon 220 signal based on the predefined frequency domain data.

When the BLE beacon 220 signal is detected, the cadastral reference point distance calculating unit 330 calculates the distance to the cadastral reference point 110 based on the reception intensity of the BLE beacon 220 signal.

In one embodiment, the cadastral reference point distance calculating unit 330 estimates the distance in the embedding direction of the estimated cadastral reference point 110 at the current position based on the RSSI (Received Singal Strength Indication) of the BLE beacon 220 signal The current position and the RSSI may be provided to the cadastral reference point management server 130. For example, the cadastral reference point distance calculation unit 330 determines that the lower the RSSI value is, the farther away from the cadastral reference point 110, and the higher the RSSI value, the closer the cadastral reference point 110 is.

In one embodiment, the cadastion point distance calculator 330 stores the position when the intensity of the signal of the BLE beacon 220 is reduced and then increases again in the moving process. If the number of the position is 3 or more, The position and orientation of the cadastral reference point 110 can be determined. The trilateration is a method of obtaining the relative position of an object using triangular geometry. In order to know the position of the object, the distance between two or more reference points, an object and each reference point is used. For example, when the reception intensity of the signal decreases and the number of increases is three or more, the cadastral reference point distance calculation unit 330 assigns the distance value estimated from the GPS coordinates of the corresponding position and the reception intensity of the signal to the trilateration algorithm The position of the cadastral reference point 110 can be determined.

If the reception strength of the BLE beacon 220 received at the current position is greater than or equal to the pre-stored reception strength at the corresponding position, the cadastral reference point abnormality notification unit 340 notifies the user of the possibility of position change or discharge possibility Can be informed. For example, when the difference between the pre-stored reception intensity at the current location and the reception intensity received from the current BLE beacon 220 is equal to or greater than a threshold value, the cadastral reference point error notification unit 340 determines that the cadastral reference point 110 is lost It is determined that the battery of the cadastral reference point 110 is discharged and the signal of the expected intensity can not be sent to the surveyor or manager. For example, the cadastral reference point error notification unit 340 may output sound and vibration to notify the surveyor or the manager of the abnormality of the cadastral reference point 110.

In addition, the cadastral reference point abnormality notifying unit 340 may receive the BLE beacon 220 received at the current position from the neighboring location preliminarily stored in the cadastral reference point management server 130 and the adjacent reception intensity at the corresponding position If there is a difference between the reception intensity and the threshold value or more, the user can be informed of the potential change of the cadastral reference point or the possibility of discharge. For example, the cadastral reference point error notification unit 340 searches for data at a position adjacent to the current position when there is no previously stored received intensity at the current position. The cadastral reference point abnormality unit 340 calculates the distance between the GPS signal at the adjacent position and the GPS signal at the current position and calculates the distance between the two positions based on the distance between the calculated reception intensity and the calculated two positions The reception intensity at the current position can be predicted. The cadastral reference point error notification unit 340 may detect that the corresponding cadastral reference point 110 has been lost or that the battery of the cadastral reference point 110 is in a state where the difference between the expected reception intensity and the reception intensity received from the current BLE beacon 220 is equal to or greater than the threshold, It is determined that the signal of the expected intensity can not be sent to the surveyor or the manager. For example, the cadastral reference point error notification unit 340 may output sound and vibration to notify the surveyor or the manager of the abnormality of the cadastral reference point 110.

The cadastral control point management unit 350 may provide the cadastral control point management server 130 with an image of the cadastral control point 110 so that the cadastral control point management server can monitor at which point the cadastral control point 110 is managed. In one embodiment, it is possible to receive from the cadastral reference point management server 130 that the management point of time of the specific cadastral reference point 110 has passed, and to provide the user with the location of the specific cadastral reference point 110. For example, the cadastral reference point management unit 350 provides a captured image to the cadastral reference point management server 130, and the cadastral reference point management server 130 determines the date of providing the captured image as a management date and stores the date. The cadastral control point management unit 350 can provide the user with a position for the cadastral control point 110 when the cadastral control point 110 having a management cycle of 6 months exceeds 6 months from the immediately preceding management day.

The server communication unit 360 can communicate with the cadastral reference point management server 130. The server communication unit 360 may provide the cadastral control point management server 130 with the current position of the user, the current RSSI and the cadastral control point 110 management image, The location of the cadastral reference point 110, and the management date of the cadastral reference point 110. [

The control unit 370 controls the overall operation of the cadastral point monitoring apparatus 120 and includes a buried region guide unit 310, a beacon signal processing unit 320, a cadastral reference point distance calculating unit 330, ), The cadastral reference point management unit 350, and the server communication unit 360. In one embodiment, the controller 370 may be implemented as a CPU of a smartphone and a notebook.

FIG. 4 is a view for explaining a result of estimating the distance of a cadastral reference point performed in the apparatus of FIG. 1, and FIG. 5 is a flowchart illustrating a cadastral reference point monitoring method performed by the apparatus of FIG.

Referring to FIG. 5, the cadastral reference point monitoring apparatus 120 detects the current position of the user to monitor the cadastral reference point 110 (step S510). Here, the cadastral reference point monitoring apparatus 120 can use the built-in GPS.

When the detection of the current position of the user is completed, the cadastral reference point monitoring apparatus 120 grasps the cadastral cadastral landing region and outputs a map guiding the cadastral landmark landing region to the cadastral landmark embedding region (step S520). The cadastral reference point monitoring apparatus 120 can overlay the map and the visual guidance in the direction of the cadastral reference point 110. [

The cadastral reference point monitoring apparatus 120 confirms whether or not the cadastral reference point monitoring apparatus 120 has reached the cadastral reference point landing region by using the GPS (step S522).

When the cadastion reference point monitoring apparatus 120 reaches the cadastral reference point landing region, the cadastion point monitoring apparatus 120 detects a signal of the BLE beacon 220 from the cadastral reference point 110 (step S530).

The cadastion reference point monitoring apparatus 120 estimates a distance in the embedding direction of the cadastral reference point 110 estimated at the current position based on the RSSI of the BLE beacon signal 220 (step S540).

4, the cadastral reference point monitoring apparatus 120 can output the RSSI distance value, the GPS distance value, and the position based on the scanned cadastral reference point, and can estimate the distance to the landing direction of the cadastral reference point 110 have.

5, the cadastral reference point monitoring apparatus 120 compares the stored RSSI reception strength provided from the cadastral reference point management server 130 with the estimated RSSI signal to check whether or not the threshold value of the reception intensity difference is exceeded (Step S542). When the threshold value is exceeded, the cadastral reference point monitoring apparatus 120 notifies the user of the possibility of the cadastral reference point 110 being abnormal (step S550).

The cadastion control point monitoring apparatus 120 receives the management date of the cadastral control point 110 in the landfill area from the cadastral control point management server 130 and checks whether the management point of time of the cadastral control point 110 in the landfill area has passed (Step S552).

When the cadastral reference point monitoring apparatus 120 confirms that the management point of time of the cadastral reference point 110 has been exceeded, it provides the user with the location of the cadastral reference point 110 (step S560).
