Call sharing system and call sharing method for construction work

1. A call sharing system for construction work, the call sharing system comprising:

an administrator terminal configured to display a working drawing of a construction site on an administrator screen and to transmit a work request signal including a work area designated on the working drawing;

a plurality of worker terminals configured to display the working drawing on each worker screen, each worker terminal being configured to receive the work request signal and to transmit a response signal in response to receiving the work request signal; and

a server configured to transmit and receive data between the administrator terminal and the worker terminals and to select a subset of worker terminals of the plurality of worker terminals for receiving the work request signal according to a work detail set by the administrator terminal in the work request signal,

wherein a first worker terminal of the plurality of worker terminal transmits a follow-up work request signal including a work request for follow-up work to be performed subsequently after a current work, and

a second worker terminal of the plurality of worker terminals receives the follow-up work request signal and transmits the response signal in response to the follow-up work request signal.

2. The call sharing system of claim 1 , wherein the administrator terminal stops transmitting the work request signal when the administrator terminal receives the response signal from a preset number of worker terminals of the plurality of worker terminals.

3. The call sharing system of claim 1 , wherein the server further includes a list of workers that classifies registered workers according to worker information, and the administrator terminal selectively transmits the work request signal according to the worker information.

4. The call sharing system of claim 3 , wherein the administrator terminal selectively transmits the work request signal according to construction machinery associated with the workers.

5. The call sharing system of claim 1 , wherein the server further include a field map, and

the administrator terminal overlays the working drawing and the field map, and displays the overlaid working drawing and field map on the administrator screen.

6. The call sharing system of claim 1 , wherein the administrator terminal displays worker information, a current location and a distance from the designated work area of the worker terminal on the administrator screen.

7. The call sharing system of claim 1 , wherein each worker terminal of the plurality of worker terminals displays worker information, a current location and a distance from the designated work area of other worker terminals of the plurality of worker terminals on the worker screen.

8. A method of call sharing for a construction work, the method comprising:

transmitting a work request signal including a work area designated on a working drawing of a construction site to a server through an administrator terminal;

selecting, by the server, based on a work detail set by the administrator terminal in the work request, a subset of worker terminals out of a plurality of worker terminals associated with the administrator terminal,;

transmitting the work request signal received through the server to a subset of worker terminals selected from the plurality of worker terminals according to the work detail; and

transmitting a response signal in response to the work request signal to the administrator terminal through worker terminals that received the work request signal,

wherein the method further comprises:

transmitting a follow-up work request signal including a work request for follow-up work to be performed subsequently after a current work to a second worker terminal of the plurality of worker terminals through a first worker terminal of the plurality of worker terminals that received the work request signal; and

transmitting the response signal in response to the follow-up work request signal to the administrator terminal and the first worker terminal through the second worker terminal.

9. The method of claim 8 , wherein the administrator terminal stops transmitting the work request signal when the administrator terminal receives the response signal from a preset number of worker terminals of the plurality of worker terminals.

10. The method of claim 8 , further comprising:

registering a group of workers including information about the workers on the construction site.

11. The method of claim 10 , wherein transmitting the work request signal to the subset of worker terminals includes selectively transmitting the work request signal according to construction machinery associated with the registered group of workers.

12. The method of claim 10 , further comprising:

displaying worker information, a current location and a distance from the designated work area of the worker terminals on an administrator screen of the administrator terminal.

13. The method of claim 10 , further comprising:

displaying worker information, a current location and a distance from the designated work area of the other worker terminal on a worker screen of the worker terminal.
