【摘要】：当今对于石油等能源的需求日益增大,促使油船不断朝着大型化和超大型化方向进展,因此我们对油船锅炉的蒸发量的需求也越来越高,然而锅炉尺寸的增加并不显著。并且,在确保锅炉安全性的同时对其经济性的需求也日益提高,因此对锅炉的自动控制系统的需求也就越来越高。船舶锅炉主要用来生成蒸汽以加热货油、滑油以及驱动甲板机械等,大型油船的蒸发量大,蒸汽压力较高,其能否安全高效运行运行对船舶能否安全航行有重要影响。本论文研究的对象是大型油船锅炉,目标是完成锅炉水位自动控制、蒸汽压力自动控制以及锅炉燃烧时序控制与安全保护控制系统。本文针对现如今船舶锅炉自动化控制系统的需求,设计出基于STM32F107作为主控芯片的VLCC船舶锅炉控制系统,硬件板卡电路设计依据船舶锅炉控制系统的控制原理,选取Cortex-M3内核的处理器STM32F107,设计船舶锅炉水位、蒸汽压力、燃油温度、燃油压力等数据的采集电路,实现信号的输入输出功能;通过STM32F107实现对信号的处理并发出控制信号,控制燃油阀、给水阀、风门等执行机构。嵌入式软件程序设计包括实时操作系统μC/OSii的移植、硬件底层驱动设计、硬件端口规划、网络通信协议设计、船舶锅炉控制系统功能任务的设计,以及在触摸屏上的实现等。基于嵌入式的VLCC船舶锅炉自动控制系统具有消耗低、应用灵便、扩展性强等优点,控制系统可以完成模块化和网络化管理,对VLCC船舶锅炉控制系统的进一步研究与发展很有意义。
[Abstract]:The oil tanker has prompted increasing demand towards large-scale and ultra large scale development direction, so we for oil tanker boiler evaporation demand more and more is also high, but increase the boiler size is not significant. And, in ensuring the safety of the boiler and the economic benefit of demand to improve the automatic control system of boiler, so the demand is more and more high. Marine boiler is mainly used to generate steam for heating oil, lubricating oil and driving deck machinery, evaporation of a large oil tanker, the steam pressure is high, the safe and efficient operation of operation of the ship can have an important impact on safe navigation. The object of this this paper is a large oil tanker boiler, the goal is to complete the boiler water level automatic control, safety control and protection of combustion timing control system and steam pressure automatic control of boiler in this paper. Now marine boiler automatic control system requirements, design a control system of marine boiler VLCC STM32F107 as the main control chip based on the control principle, hardware circuit design of control system of marine boiler, selection of Cortex-M3 core processor STM32F107, the design of marine boiler, steam pressure, oil temperature, oil pressure data acquisition circuit. The input and output signal; through the STM32F107 to realize the signal processing and control signal, control valve, throttle valve, fuel, and other implementing agencies. Embedded software programming including the real-time operating system C/OSii transplant, hardware driver design, hardware port planning, network communication protocol design, control system design tasks marine boiler, as well as the realization of the touch on the screen. VLCC embedded marine boiler automatic control system is based on. Low power consumption, application flexibility, scalability, the control system can complete the modular and network management, it is of significance to further research and development of VLCC control system of marine boiler.
