Abstract: A call sharing system for a construction work includes 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 the work request signal, and a server configured to transmit and receive data between the administrator terminal and the worker terminals and to select the worker terminals for receiving the work request signal according to a work detail.

Abstract: In a method of making work plans for construction machinery, information of the construction machinery at a work site is obtained. The information of the construction machinery is received via a wireless communication. The information of the construction machinery is displayed on a display portion of a server. A work plan of the construction machinery is created on the display portion of the server by using the information of the construction machinery and information stored in the server. The work plan is transmitted to the construction machinery.

Abstract: A control system for construction machinery includes 3D camera configured to recognize an object located around construction machinery and capture an image, a position information receiving device configured to obtain a reference coordinate corresponding to a position of the construction machinery, a data processing device configured to obtain a relative coordinate of the object relative to the construction machinery from the image and convert the relative coordinate based on the reference coordinate to obtain a three-dimensional coordinate, and a control device configured to display the image having the three-dimensional coordinate on a screen.

Abstract: In a method of making a work plan for construction machinery, construction site information including an orthographic image and work data are provided. A trench excavation work plan on the orthographic image is set based on the work data. The trench excavation work plan is configured to displays a work route line and a work position of construction machinery based on the work route line. The trench excavation work plan is transmitted to a worker terminal.
