嵌入式油水分离器控制模块的软硬件设计
|
摘要
鉴于在当前轮机模拟器中油水分离器控制模块缺少含油质量分数的仿真、报警记录和参数的存储以及人机交互界面的设计等功能,通过分析RWO油水分离器的工作原理和运行逻辑,提出一种新型嵌入式油水分离器仿真模块。根据模块的功能需求,选取STM32F103xx为主芯片,W5100为网络芯片,通过Altium Designer设计16DI8DO4AI印制电路板(printed circuit board,PCB)。进行嵌入式操作系统μC/OS-II的裁剪和移植,根据所使用的模块对板载外设库进行初始化,基于运行逻辑进行多任务程序设计。试验表明,嵌入式油水分离器控制模块能够实现含油质量分数的采集,适时触发含油量超限报警并同步更新报警信息和阀位,用TFT液晶屏能够实现对参数值和运行状态的实时显示。该模块具有很高的应用价值和良好的可扩展性。
For current marine engine room simulators,the oily water separator control module lacks the functions of the simulation of oil mass fraction,storage of alarm records and parameters,and design of human-machine interaction interface. In view of this,by analyzing the working principle and running logic of RWO oily water separator,a new embedded oily water separator simulation module is designed. According to functional requirements of the module,STM32 F103 xx is selected as the main chip,W5100 is selected as the network chip,and 16 DI8 DO4 AI PCB( printed circuit board) is designed by Altium Designer. Tailoring and transplanting embedded operating system μC/OS-II,the board support package is initialized based on the module used. Based on the running logic,the multi-tasking program is designed.Experiments show that,the embedded oily water separator control module can realize the collection of oil mass fraction,timely trigger the oil content high alarm,and synchronously update the alarm information and valve position,and implement the real-time display of parameter values and running status by TFTLCD screen. The module is of high application value and good scalability.
