FIG. 3 is a view for explaining a road map generation process according to an embodiment of the present invention. FIG. 8 is a diagram for explaining a route map update and a route guidance process according to an embodiment.

Referring to FIG. 2, the work location guidance system may include a guide device 200 and one or more worker terminals 250.

The worker terminal 250 is a communication terminal for communicating with the guide device 200 and may be a portable device carried by an operator who performs work such as construction, welding, inspection, etc. in a plant such as a tablet PC or a smart phone.

The worker terminal 250 may perform processing such as scanning and interpreting the marker 310, receiving and displaying design data and road maps.

Specifically, the operator terminal 250 analyzes marker information embedded in the marker 310 by scanning the marker 310 (see FIG. 3) installed at each position in the plant, for example, (For example, a two-dimensional design drawing, a three-dimensional model, etc.) designated to correspond to the marker 310, and displays the received design data on the display unit.

Each marker 310 has marker information that allows the mounted position to be recognized. Accordingly, when the operator terminal 250 transmits the marker information to the guide device 200, the design data corresponding to the position where the marker 310 scanned from the guide device 200 is installed can be provided, By taking into consideration the displayed design data and the construction conditions already recognized, it is possible to easily grasp the work position to be visited.

When the operator selects an arbitrary object (for example, spool or the like) from the design data displayed on the display unit of the worker terminal 250, the operator scans the worker terminal 250 from the position of the marker 310 scanned by the operator, It may be set in advance so that the movement route is displayed.

The worker terminal 250 may be preset to transmit real-time position information to the guiding device 200, for example, with an inertia measurement unit (IMU) or with a built-in GPS module. Of course, the real-time position of the worker terminal 250 may be realized in real time in the guide device 200 in a manner such as triangulation, for example.

The operator terminal 250 may also receive the road map from the guide device 200 and display the received road map on the display unit in accordance with the transmitted marker information, as described later (FIGS. 3B and 3C) 4 (e)). The road map may include a node 320 and a connection line 330. The display of the operator terminal 250 may display only the node 320 or display the node 320 and the connection line 330 in advance Can be specified.

In addition, when the operator selects an arbitrary node 320 (see FIG. 3), a recommended route for moving from the position of the operator calculated by the guide device 200 to the selected node 320 is received and displayed on the display unit 3 (c) and 4 (f)).

The guide device 200 may include a storage unit 210, a design data management unit 212, a location management unit 214, a road map management unit 216, and a communication unit 218.

The storage unit 210 may store installation location information of the marker 310, design data corresponding to each location in the plant (e.g., two-dimensional design drawing, three-dimensional model, etc.) The route information, the route information, the route map, and the like generated by the route map management unit 216 in correspondence with the positional information of the worker terminal 250 in each space in the plant. Design data, node information, road map information, and the like may be stored and managed corresponding to the marker 310 installed at each location.

When the marker information is received from the worker terminal 250, the design data management unit 212 transmits the design data corresponding to the marker information (that is, the design data corresponding to the position in the plant where the worker is located) to the worker terminal 250 . For example, when the worker terminal 250 scans the marker 310 installed at the entrance to the third floor of the field management building, the design data management unit 212 uses the marker information to transmit the design data for the third floor of the field management building to the worker terminal 250). Here, the design data may include information on the mounting position of each marker.

The location management unit 214 generates location information of each worker terminal 250, which is changed in each space in the plant, in real time, and stores the generated location information in the storage unit 210. The real-time position of the worker terminal 250 may be transmitted in real time, for example, at the worker terminal 250, or may be real-time recognized by the position manager 214 using a technique such as triangulation.

When the marker information is received from the operator terminal 250 that scanned the marker 310 installed at each position in the plant, the position management unit 214 extracts the installation position information of the scanned marker 310 from the storage unit 210 Thereby correcting the real-time position information of the worker terminal 250. [ Accordingly, it is possible to eliminate a position measurement error that may be cumulatively generated in the process of moving the worker terminal 250.

The road map management unit 216 performs generation of the road map, update processing of the generated road map, and the like.

Specifically, the route map management unit 216 analyzes the change (i.e., position change) of the location information of each worker terminal 250 stored in the storage unit 210 according to a predetermined condition and generates node information and connection line information, respectively And stores it in the storage unit 210.

3 (a), when a plurality of operators move from the position 1 to the position 2 by each movement path, the road map management unit 216 determines whether or not the movement direction is changed over, for example, A position where the worker terminal 250 has stayed for a predetermined time or longer as a node 320 and information on the position of each node 320 as node information.

In addition, the route map management unit 216 specifies a route through which each worker travels between the two nodes 320 as a connection line 330 connecting the respective nodes 320, and transmits information about the specified travel route as connection line information Can be generated. Here, the movement path of the worker moving between the two nodes may vary, and correspondingly, there may be a plurality of connection lines.

The road map management unit 216 generates a road map using the node 320 and the connection line 330 stored in the storage unit 210 so as to overlap the predetermined number of times or more in each space in the plant ).

The generated road map is a representation of a path that is repeatedly moved when a plurality of workers move to respective working positions by a node 320 and a connecting line 330.

Therefore, as illustrated in FIG. 3 (b), not only the area where the floor construction is completed, but also the scaffold 120 such as a chieftain which is installed in the non-construction area 105 or temporarily installed on the exterior wall of the building, Each can be included in the road map. That is, the area A shown in FIG. 3 (b) can not constitute a moving path as a wall surface on the design data, but in the present construction situation, the building 120 constitutes a moving path as shown in FIG. 3 (a) It is included on the road map.

When the marker information is received from the worker terminal 250, the pathway management unit 216 may transmit a pathway map corresponding to the marker information to the worker terminal 250. The road map received by the worker terminal 250 may be previously displayed so as to be overlapped with the design data provided by the design data management unit 212 or displayed independently of each other according to the operation of the operator.

As illustrated in FIGS. 3 (b) and 3 (c), when the operator at position 1 is to move to position 2, the operator moves the node The node selection information is transmitted to the route guidance management unit 216. [ The route map management unit 216 calculates a recommended route between the location 1 corresponding to the received marker information (or the real-time location information of the worker terminal 250 stored in the storage unit 210) and the location 2 corresponding to the node selection information To the worker terminal 250. The recommended route can be calculated with the shortest distance, for example, using one or more nodes and connection lines in the route map.

Of course, the worker terminal 250, which has already received the design data and the road map, can calculate the recommended route from the current position of the worker terminal 250 to the node 320 selected by the worker using the road map, It is a matter of course.

The road map generated by the road map management unit 216 may be continuously updated so as to correspond to a change in the movement path of the workers according to the construction progress (i.e., the movement path of the worker terminal 250).

For example, when the work for the construction section 105 illustrated in FIG. 3 (a) is completed, the area A can not constitute a movement path as a wall surface as illustrated in FIG. 4 (d). However, if the route map is maintained as shown in FIG. 3 (b), if the operator at the location 1 selects the corresponding node 320 to move to the location 2, the route passing through the area A is presented to the worker terminal 250 as a recommended route Will be.

However, the operator can not proceed along the suggested route formed by the area A as the wall surface, and moves to the position 2 through the bypass path 410. At this time, the real time location change of the worker terminal 250 is recognized by the location management unit 214, and the route guidance management unit 216 can recognize the travel route of the worker. In this process, the road map management unit 216 may additionally generate the node 320 and the connection line 330 corresponding to the movement path of the operator.

For updating the generated route map, the route map management unit 216 can generate the contrast information by comparing the recommended route and the actual travel route of the worker terminal 250.

The contrast information may include, for example, a departure interval 420, a departure interval 420, a departure interval 420, and a departure interval 420 when the worker terminal 250 moves along the recommended route, But may instead include information about the bypass path 410, which is the moved path.

If the worker terminal 250 always moves using only the bypass 410 in some of the nodes included in the recommended route, the route map managing unit 216 may determine that the route connecting the corresponding nodes is more And the road map may be updated (see Fig. 3 (b) and Fig. 4 (e)). When the road map is updated, it is natural that the recommended route is presented using the updated road map for subsequent node selection information (see FIG. 4 (f)).

This is because, for example, the route guidance management section 216 has provided a recommended route of "Nodes A-B-C "; however, The nodes B to C are temporary sections through the construction 120 and the paths of the nodes B to D are completed and the construction of the nodes B to C is completed 120) may have been demolished.

The communication unit 218 communicates with each worker terminal 250 located in each space in the plant through a communication network for transmitting and receiving marker information, design data, road map, and the like.

FIG. 5 is a flowchart illustrating a process of generating a route map of a work location guidance method according to an embodiment of the present invention.

Referring to FIG. 5, in step 510, the guiding device 200 transmits design data corresponding to marker information to the worker terminal 250 that transmitted the marker information.

The marker 310 installed at each position in the plant includes information corresponding to the corresponding position to be installed. Accordingly, the operator terminal 250 can receive the design data corresponding to the corresponding position by transmitting the marker information analyzed by scanning the marker 310 to the guide device 200, and consider the provided design data and the construction status So that the movement path to the working position can be determined.

The guiding device 200 recognizes the connection line 330 (that is, the movement route) between the node 320 and each of the nodes 320 by referring to the real-time position change of the worker terminal 250 in step 520, The connection line information is generated and stored.

In step 530, when there is node information and connection line information stored in the storage unit 210 so as to overlap the predetermined number of times or more, the guide apparatus 200 uses the node information and the connection line information to generate a route map corresponding to the corresponding space in the plant . Of course, if the road map has already been generated, the road map may be updated using the node information and the link information.

FIG. 6 is a flowchart illustrating a process of providing a recommended route and updating a route map of the work location guidance method according to an embodiment of the present invention.

Referring to FIG. 6, in step 610, the guiding device 200 transmits the design data and the road map corresponding to the marker information to the worker terminal 250 that transmitted the marker information.

The road map received at the worker terminal 250 may be displayed so as to be overlapped with the design data according to the operation of the operator or may be preset to be displayed independently of each other. For example, a road map composed of the node 320 and the connection line 330 may be displayed on the display unit of the worker terminal 250 only when the node 320 is overlapped with the design data or when the node 320 and the connection line 330 are displayed All can be specified in advance to be superimposed on the design data.

In step 620, the guiding device 200 determines whether node selection information for any node in the road map (e.g., node aligned to match the job location) is received.

If the node selection information is received, the guiding device 200 calculates a recommended route for moving from the current position of the worker terminal 250 to the selected node, and transmits the recommended route to the worker terminal 250 in step 630.

The recommended route can be calculated with the shortest distance, for example, using one or more nodes and connection lines in the route map. The recommended route calculation may be performed by the operator terminal 250 itself using the received route map.

In step 640, the guiding device 200 refers to a change in the position of the worker terminal 250 and determines whether or not there is a departure section 420 deviating from the suggested recommended route.

If the departure interval 420 does not exist, the flow returns to step 620 to determine whether node selection information for any other node is received.

However, if the departure interval 420 exists, the guiding device 200 continuously calculates the departure interval 420 in the recommended routes calculated and previously calculated for the predetermined number of times to include the departure interval 420, . ≪ / RTI >

If it is not the continuous departure interval 420 for a predetermined number of times, the flow returns to step 620. [

However, if it is the predetermined departure interval 420 for a predetermined number of times, in step 660, the guiding device 200 recognizes that there is no more route connecting between the nodes corresponding to the departure interval 420, Update the map and save it.

In the above-described process, it is a matter of course that a change in the position of the worker terminal 250 is recognized, and a new node and a connection line for updating the road map may be additionally generated.

As described above, according to the present embodiment, when the marker 310 installed in the vicinity of the work space is scanned, design data corresponding to the position is provided, so that the worker can easily recognize the work position There is a feature that makes it possible. Also, in consideration of the design data and the construction status, a road map is accumulated by accumulating past travel paths in which a plurality of workers have moved to respective work positions, and guidance is provided to the operator using the generated road map, There is also a feature that an easy movement can be performed.

It is a matter of course that the above-described work position guiding method may be performed by an automated procedure in a time-series sequence by a software program or the like embedded in the digital processing apparatus. The codes and code segments that make up the program can be easily deduced by a computer programmer in the field. In addition, the program is stored in a computer readable medium, readable and executed by a computer, thereby implementing the method. The information storage medium includes a magnetic recording medium, an optical recording medium, and the like.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the following claims And changes may be made without departing from the spirit and scope of the invention.
