1. A method for integrated online monitoring for a nuclear power plant from a remote location using an online integrated monitoring system including a monitoring data relay device, a diagnostic data relay device, and a local data acquisition device, the method comprising:
a first step of collecting machine monitoring data of a plurality of units in the nuclear power plant selectively by the local data acquisition device via the monitoring data relay device and
a second step of collecting machine diagnostic data of a plurality of units in the nuclear power plant selectively by the local data acquisition device via the diagnostic data relay device,
wherein the first step includes:
transmitting the machine monitoring data to the monitoring data relay device from a power plant monitoring system via a unidirectional communication cable, wherein the unidirectional communication cable, which enables physical unidirectional communication, is installed between the power plant monitoring system and the monitoring data relay device, and
wherein the second step includes:
transmitting, by the diagnostic data relay device, the machine diagnostic data to the local data acquisition device via an embedded unidirectional communication cable by transforming the machine diagnostic data into digital data, wherein the embedded unidirectional communication cable, which enables physical unidirectional communication, is in the diagnostic data relay device.
