Ships boiler PLC control design For the ship with the boiler system's control, specially the large-scale boiler system's control which uses for the large-scale freighter or the oil tanker, has been the ships turbine technology and an automated technology important topic, because this control not only directly involves to the boiler operation efficiency potency, moreover relates the security which and the reliability it moves. Has not been able to satisfy the modern ships by the contact device air relay old generation control system primarily to be getting higher and higher to its boiler control, more and more complex request, this domain computerizes the potential by to the line, but applies programmable controller (PLC) which introduces in the current commercial run control domain gazes is also causes it to computerize is simplest and the reliable way. This article main introduction programmable controller (PLC) key job principle, Mitsubishi Corporation researches and develops the FX2N-32MRPLC programmable controller and the large-scale oil tanker boiler's canonical system, based on this to used FX2N-32MRPLC to control the large-scale ships oil-fired boiler to carry on the programming. And has used the PID control separately to the large-scale ships boiler's water level and the steam pressure. At the same time, to realize the communication, establishes the localized network.
