Kind Code:
A1
Abstract:
The present invention relates to a light line system which relays bidirectional communication between a field worker working in the field and an outside worker working outside of the field and is installed to extend from the outside to the field so that the field worker can use the light line system when moving outside. The light line system comprises: a first communication unit for converting a voice input from a field worker into a relay signal, and converting a relay signal transmitted from an outside worker into a voice; a second communication unit for performing communication with the first communication unit; an external communication unit for performing processing to output a voice of a field worker, which has been transmitted from the second communication unit, and transmit a voice input from an outside worker to the second communication unit; a communication unit connected between the external communication unit and the second communication unit so as to transfer a signal; and a surrounding unit for surrounding the communication unit to prevent the communication unit from being exposed to the outside.
