Research Of The Paralleling And Protection Unit Of Ship Power Station And Its Interactive Interface

With the rapid development of science and technology, the automatic level of modern ships has been also improved. Ship Power Station must provide modern ship stable and sustainable electricity is an important guarantee for the safe navigation of the ship, and directly affects on the vitality of the ship. As this result, it is particularly important for the Ship Power Station’s monitoring, controlling and process management. According to relevant information and technical specifications of Ship Power Station management, takes the existing paralleling and protection unit of Ship Power Station in laboratory as a reference base, uses the embedding technique, Based on multi-agent system for ship power station paralleling and protection unit and for the simulation study. The PPU of Ship Power Station interactive interface has been redesigned in use of LCD which is widely used in electronic products.This article describes the working principle and main function of Ship Power Station paralleling and protection unit briefly introduces acquisition circuit of relational signal, particularly describes the process of PPU’s parameter protection and self-motion paralleling function. It focuses on the working principle of the touch screen; it has a careful explain about the detection and coordinate calculation of touch point. It is also analyzed the advantages and disadvantages of different types of touch screens by horizontal comparison. It used STM32 microcontroller with ARM Corecx_M3 core as core processor, and embed μC/GUI system. It is finely explained how to transplant μC/GUI system into STM32 microcontroller. Redesigned the human-computer interaction interface of Ship Power Station PPU by using of a four wire resistive touch screen. Through simulation, it can basically achieved PPU’s related parameter setting and warning functions.
