Independence Enforced One-Way Communication System in Nuclear Power Plant

摘要

The specification relates to a control system in a nuclear power plant. The control system includes a safety device, a control monitor for generating a control signal for controlling the safety device, a channel control gateway for transmitting the control signal on a first channel configured for the security device, and an ESF-CCS soft control module (ESCM) for receiving the control signal generated from the control monitor and transmitting the control signal to the channel control gateway. The control signal is set to be mutually independent of a control signal on the second channel of another safety device. So, it is possible to enhance independence between the channels of safety devices.
