UNDERWATER TWO WAY WIRELESS DATA COMMUNICATION SYSTEM AND METHOD THROUGH SENSING MINOR CHANGE OF LIGHT AMOUNT IN DIFFUSED LIGHT IN UNDERWATER TURBIDITY CONDITION

摘要

An object of the present invention is to secure high linearity by increasing light intensity with concentrated light at a light-emitting part, and to realize a data communication within an audible voice band in a underwater turbidity environment by sensing a minor change of environment brightness at a light-receiving part. For the purposes, the present invention discloses a underwater two way wireless data communication system by sensing a minor change of a light amount in diffused light in a underwater turbidity environment, comprising: a wireless data communication device including a light-receiving part connected to a microphone plug of a mobile communication terminal, and converting a light signal to an electrical signal, a comparator connected to an earphone plug of the mobile communication terminal, and converting a voice signal to an electrical signal and a light-emitting part receiving the electrical signal of the comparator and converting the electrical signal to a light signal; and a lighting support device providing light brighter than the light of the light-emitting part to at least a communication area between the wireless data communication device and another wireless data communication device having the same configuration as the wireless data communication device in a underwater communication between the wireless data communication device and the another wireless data communication device.;COPYRIGHT KIPO 2017
