Chapter 18 - Programmable electronic systems

Abstract

This chapter discusses the application of programmable electronic system (PES) to power management systems. PES is becoming common on the modern ship. They are used for monitoring and control functions, varying in size and complexity from the load computer to an integrated machinery monitoring and cargo handling system that can be operated from the bridge. Many systems have been developed that are suitable for the applications on a ship and on the arduous environment onboard. PES is used on ships for: (1) continuous monitoring of the performance and condition of main engines; (2) power management systems; (3) tank gauging systems; (4) safety systems; and (5) dynamic positioning systems. A PES includes the sensors and/or actuators that are the direct interface to the plant being monitored/controlled and input and output modules that are required to interface the sensors and actuators to the programmable part of the system. There is likely to be an operator interface, an interface to access the program within the system, and interfaces to other programable systems.
